    Reference citations should be accurate, complete, and presented in a consistent format. This study analyzed information provided to authors on preparing citations and references for manuscripts submitted to nursing journals (n = 209). Half of the journals used the American Psychological Association reference style. Slightly more than half provided examples of how to cite articles and books; there were fewer examples of citing websites and online journals. Suggestions on improving accuracy of references are discussed. PMID:29346137

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

    The paper reviews results of a research on literature cited in papers published in two most remarkable Yugoslav biomedical journals, Medicinski Pregled and Srpski arhiv za celokupno lekarstvo, in 1985 and 1992. The analysis included the following parameters: the amount of published papers, the quantity of cites out of the literature that has been used, frequency of citation of foreign and domestic literature as well as the quantity of self citations. According to the gathered results, foreign literature is remarkably more often cited than the domestic references, mostly in English, but the percentage of citing one's own papers is also high.

    There is an abundance of works published on severe traumatic brain injury (sTBI). Bibliometric analyses aim to provide a macroscopic view of research activities regarding sTBI and are helpful in determining the most impactful studies within this field. We performed a generalized search using the database of Web of Science, organized the references by the number of citations, and reviewed full length-articles for the top-100 most-cited articles on sTBI. The articles were classified according to focus. The top-100 articles were cited on average 326.4 times per paper. The Journal of Neurosurgery published the greatest number of top-100 cited articles (9 of 100). Authors from the United States published the majority (67%) of the most-cited articles. The most popular categories were "reviews and guidelines" and "etiology and epidemiology." The present study provides a cross-sectional summary of the 100 most-cited articles on sTBI, highlighting areas of research needing further investigation and development.

    Full Text Available This article aims to analyze motivations behind social sciences blog posts citing journal articles in order to find out whether blog citations of scholarly journal articles are good indicators for the societal impact of research. A random sample of 300 social sciences blog posts (out of 1,233 blog posts from ResearchBlogging published between 01/01/2012 to 18/06/2014 were subjected to content analysis. An existing categorization scheme was used and modified inductively. The 300 blog posts had 472 references including 424 journal articles from 269 different journals. Sixty-one (22.68% of all journals cited were from the category of social sciences and most of the journals with high frequency were highly cited general science journals such as PNAS and Science. Seventy-five percent of all journals were referenced only once. The average age of articles cited was 5.8 years. The most frequent (38, 12.67% motivation was to ‘neutrally presenting details of a study’. Overall, social science blogs were rather subject-oriented than article oriented. This means a considerable number of blog posts were not driven simply by writing about an article, instead bloggers tend to write about their subject of interest and use references to support their argument. The study shows the potential of blog citations as an altmetric measure and as a proxy for assessing the research impact.

Design – Field simulation (unobtrusive testing.Setting – Large public libraries in the United States and Canada.Subjects – Telephone reference staff of the 25 largest public libraries in the United States and Canada.Methods – The 2005 World Book Almanac was used to select the 25 largest (in terms of population served public libraries in Canada and the United States. Each system’s Web site was checked to locate the telephone number for reference service. For some systems it was necessary to call the general telephone number for the main library or the first branch listed on the Web site. Five ready reference test questions were developed from a list of questions that students in a graduate library and information science course had previously asked of public library telephone reference services. The selected questions in the order that they were asked were: 1. Can you tell me when Valentine’s Day is?2. Who is the current governor/premier (of the state/province where the library is located?3. What is the population of Montana?4. In which state is the Southern Poverty Law Center (SPLC located?5. What is the French word for “chiropractor”?The authors called each of the 25 libraries during five consecutive weeks at different times of the business day. Each week, one question was asked; once an answer was received, no clarification was requested and the call was ended. The study reports the results of 125 reference transactions. For this study, the following definitions were used to assess complete citation for each type of information resource:• For a Web site – the complete URL (title and sponsor of the site not required.• For a digital database – the database title and the title and year of the specific item (author, publisher, page number not required.• For a print resource – the title

    Full Text Available Abstract Background CITED proteins belong to a family of non-DNA-binding transcriptional co-regulators that are characterized by a conserved ED-rich domain at the C-terminus. This family of genes is involved in the regulation of a variety of transcriptional responses through interactions with the CBP/p300 integrators and various transcription factors. In fish, very little is known about the expression and functions of CITEDs. Results We have characterized two closely related but distinct CITED3 genes, gcCited3a and gcCited3b, from the hypoxia-tolerant grass carp. The deduced gcCITED3a and gcCITED3b proteins share 72% amino acid identity, and are highly similar to the CITED3 proteins of both chicken and Xenopus. Northern blot analysis indicates that the mRNA expression of gcCited3a and gcCited3b is strongly induced by hypoxia in the kidney and liver, respectively. Luciferase reporter assays demonstrated that both gene promoters are activated by gcHIF-1. Further, ChIP assays comparing normal and hypoxic conditions reveal differential in vivo binding of gcHIF-1 to both gene promoters in kidney and liver tissues. HRE-luciferase reporter assays demonstrated that both gcCITED3a and gcCITED3b proteins inhibit gcHIF-1 transcriptional activity, and GST pull-down assays confirmed that both proteins bind specifically to the CH1 domain of the grass carp p300 protein. Conclusion The grass carp gcCITED3a and gcCITED3b genes are differentially expressed and regulated in different fish organs in response to hypoxic stress. This is the first report demonstrating in vivo regulation of two closely-related CITED3 isogenes by HIF-1, as well as CITED3 regulation of HIF-1 transcriptional activity in fish. Overall, our findings suggest that unique molecular mechanisms operate through these two gcCITED3 isoforms that likely play an important regulatory role in the hypoxic response in the grass carp.

    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

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

    To identify and characterize the top-cited articles in the field of islet transplantation. 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. 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. 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.

    This study investigates the progress of highly cited research in China from 2001 to 2016 through the analysis of the Highly Cited database. The Highly Cited database, compiled by Clarivate Analytics, is comprised of the world's most influential researchers in the 22 Essential Science Indicator fields as catalogued by the Web of Science. The database is considered an international standard for the measurement of national and institutional highly cited research output. Overall, we found a consistent and substantial increase in Highly Cited Researchers from China during the timespan. The Chinese institutions with the most Highly Cited Researchers- the Chinese Academy of Sciences, Tsinghua University, Peking University, Zhejiang University, the University of Science and Technology of China, and BGI Shenzhen- are all top ten universities or primary government research institutions. Further evaluation of separate fields of research and government funding data from the National Natural Science Foundation of China revealed disproportionate growth efficiencies among the separate divisions of the National Natural Science Foundation. The most development occurred in the fields of Chemistry, Materials Sciences, and Engineering, whereas the least development occurred in Economics and Business, Health Sciences, and Life Sciences.

    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

    Physicists who search the literature on elementary particles know that the SLAC library's SPIRES-HEP database provides an essential tool. The database lists virtually every paper published or even preprinted in high energy physics over the past thirty years. The database connects preprint or eprint versions to articles published in journals or conference proceedings, providing access to all phases of the publication history. In addition, most papers have backward links to the papers they cite and forward links to the papers citing them. These citation linkages provide a very effective means of searching the literature on any topic of interest. In the past few years, SPIRES-HEP has been automatically harvesting reference citations from eprints, creating a web of links which indexes the literature in a quite thorough manner. As a byproduct of this citation linkage, SPIRES-HEP can easily search out the papers most highly cited by publications in high-energy physics. The list of papers with the most citations in a given year provides a snapshot of the hottest topics that have engaged the attention of theorists and experimenters. For the past several years, SPIRES-HEP has posted a scientific review of the year's top-cited papers. The whole collection of these reviews can be found on the Web at: http://www.slac.stanford.edu/library/topcites/. We have recently posted the topcite lists for the year 2000. These materials include a list of the papers with more than 100 citations in the past year, and a list of the paper with more than 1000 citations over the history of the SPIRES-HEP database

    The number of citations a publication receives can be used to show its impact on a field of study. It may indicate the educational interest in a given population or underline a perceived or real educational gap. This article identifies and characterizes the 100 top cited publications in radiologic journals as of May 2013. All clinical radiologic journals listed by Thomson Reuters Journal Citation Reports in 2011 were identified. A total of 46 journals were identified, and all articles published within these journals were analyzed for citation counts. The top 100 highly cited articles were recorded. The most frequently cited radiologic articles appeared in 9 of the 46 journals. These included 59 articles in Radiology, 17 in Journal of Nuclear Medicine, 9 in the American Journal of Roentgenology, 5 in the British Journal of Radiology, 4 in Investigative Radiology, 2 in American Journal of Neuroradiology, 2 in European Radiology, 2 in Radiologic Clinics of North America, 1 in the Seminars in Nuclear Medicine, and 1 in Pediatric Radiology. The citation values ranged from 422 to 7506 with a mean of 751. Publication dates ranged from 1967 to 2006 with the 5-year period between 1986 and 1990 accounting for the largest percentage of articles. The most frequently studied radiologic modality was magnetic resonance imaging (MRI; 28 articles), followed by vascular/interventional (19 articles) and nuclear medicine (13 articles). The central nervous system was the most frequently studied organ system (22 articles), followed by mixed organ systems (14 articles) and liver (12 articles). The top cited articles in radiologic journals span a wide range of imaging modalities, subspecialties, and organ systems. Topics that occurred frequently in the top 100 cited articles included contrast and radiopharmaceutical characterization, MRI of motion, percutaneous radiofrequency ablation in the liver and percutaneous vertebroplasty.

    Full Text Available Hepatoblastoma, the most common pediatric liver cancer, consists of epithelial mixed embryonal/fetal (EMEF and pure fetal histologic subtypes, with the latter exhibiting a more favorable prognosis. Few embryonal histology markers that yield insight into the biologic basis for this prognostic discrepancy exist. CBP/P-300 interacting transactivator 1 (CITED1, a transcriptional co-activator, is expressed in the self-renewing nephron progenitor population of the developing kidney and broadly in its malignant analog, Wilms tumor (WT. In this current study, CITED1 expression is detected in mouse embryonic liver initially on post-coitum day 10.5 (e10.5, begins to taper by e14.5, and is undetectable in e18.5 and adult livers. CITED1 expression is detected in regenerating murine hepatocytes following liver injury by partial hepatectomy and 3,5-diethoxycarbonyl-1,4-dihydrocollidine. Importantly, while CITED1 is undetectable in normal human adult livers, 36 of 41 (87.8% hepatoblastoma specimens express CITED1, where it is enriched in EMEF specimens compared to specimens of pure fetal histology. CITED1 overexpression in Hep293TT human hepatoblastoma cells induces cellular proliferation and upregulates the Wnt inhibitors Kringle containing transmembrane protein 1 (KREMEN1 and CXXC finger protein 4 (CXXC4. CITED1 mRNA expression correlates with expression of CXXC4 and KREMEN1 in clinical hepatoblastoma specimens. These data show that CITED1 is expressed during a defined time course of liver development and is no longer expressed in the adult liver but is upregulated in regenerating hepatocytes following liver injury. Moreover, as in WT, this embryonic marker is reexpressed in hepatoblastoma and correlates with embryonal histology. These findings identify CITED1 as a novel marker of hepatic progenitor cells that is re-expressed following liver injury and in embryonic liver tumors.

    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.

  6. Functional significance of SRJ domain mutations in CITED2.

    Directory of Open Access Journals (Sweden)

    Chiann-mun Chen

    Full Text Available CITED2 is a transcriptional co-activator with 3 conserved domains shared with other CITED family members and a unique Serine-Glycine Rich Junction (SRJ that is highly conserved in placental mammals. Loss of Cited2 in mice results in cardiac and aortic arch malformations, adrenal agenesis, neural tube and placental defects, and partially penetrant defects in left-right patterning. By screening 1126 sporadic congenital heart disease (CHD cases and 1227 controls, we identified 19 variants, including 5 unique non-synonymous sequence variations (N62S, R92G, T166N, G180-A187del and A187T in patients. Many of the CHD-specific variants identified in this and previous studies cluster in the SRJ domain. Transient transfection experiments show that T166N mutation impairs TFAP2 co-activation function and ES cell proliferation. We find that CITED2 is phosphorylated by MAPK1 in vitro at T166, and that MAPK1 activation enhances the coactivation function of CITED2 but not of CITED2-T166N. In order to investigate the functional significance in vivo, we generated a T166N mutation of mouse Cited2. We also used PhiC31 integrase-mediated cassette exchange to generate a Cited2 knock-in allele replacing the mouse Cited2 coding sequence with human CITED2 and with a mutant form deleting the entire SRJ domain. Mouse embryos expressing only CITED2-T166N or CITED2-SRJ-deleted alleles surprisingly show no morphological abnormalities, and mice are viable and fertile. These results indicate that the SRJ domain is dispensable for these functions of CITED2 in mice and that mutations clustering in the SRJ region are unlikely to be the sole cause of the malformations observed in patients with sporadic CHD. Our results also suggest that coding sequence mutations observed in case-control studies need validation using in vivo models and that predictions based on structural conservation and in vitro functional assays, or even in vivo global loss of function models, may be

    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.

    Citation analysis is the field of bibliometrics that uses citation data to evaluate the scientific recognition and the influential performance of a research article in the scientific community. The aim of this study was to conduct a bibliometric analysis of the top-cited articles pertaining to implant dentistry, to analyze the main characteristics, and to display the most interesting topics and evolutionary trends. The 100 top-cited articles published in "Dentistry, Oral Surgery, and Medicine" journals were identified using the Science Citation Index Database. The articles were further reviewed, and basic information was collected, including the number of citations, journals, authors, publication year, study design, level of evidence, and field of study. The highly cited articles in implant dentistry were cited between 199 and 2,229 times. The majority of them were published in four major journals: Clinical Oral Implants Research, International Journal of Oral & Maxillofacial Implants, Journal of Clinical Periodontology, and Journal of Periodontology. The publication year ranged from 1981 to 2009, with 45% published in a nine-year period (2001 to 2009). Publications from the United States (29%) were the most heavily cited, followed by those from Sweden (23%) and Switzerland (17%). The University of Göteborg from Sweden produced the highest number of publications (n = 19), followed by the University of Bern in Switzerland (n = 13). There was a predominance of clinical papers (n = 42), followed by reviews (n = 25), basic science research (n = 21), and proceedings papers (n = 12). Peri-implant tissue healing and health (24%), implant success/failures (19.2%), and biomechanical topics (16.8%) were the most common fields of study. Citation analysis in the field of implant dentistry reveals interesting information about the topics and trends negotiated by researchers and elucidates which characteristics are required for a paper to attain a "classic" status.

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

    The examination of top-cited studies is a useful method for identify and monitoring outstanding scientific research. The objective of this study was to identify and analyse the characteristics of the top 100 cited research studies on tuberculosis (TB) based on the Web of Knowledge. Overall, the top 100 cited studies were cited between 366 and 4443 times, and were published between 1995 and 2010, with the largest number of publications in 2003 and in 1995. Four studies were attributed to a single author and 10 to two authors; the number of authors exceeded six in 50 studies. Nine authors had more than one study as the first author and 18 authors had more than one study as the corresponding author. The United States contributed the largest number of studies, followed by the United Kingdom and France. The institutions with the largest number of articles were the Institut National de la Santé et de la Recherche Médicale in France and the University of California in the United States. The studies appeared in 35 journals, with 11 published in Science, followed by PNAS and NEJM. The majority of TB articles have been published in those medical journals with the highest impact factors, and are from the most industrialised countries.

    The purpose of this study was to use Web of Knowledge to determine which published arthroscopic surgery-related articles have been cited most frequently by other authors by ranking the 25 most cited articles. We furthermore wished to determine whether there is any difference between a categorical "journal-by-journal" analysis and an "all-database" analysis in arthroscopic surgery and whether such a search methodology would alter the results of previously published lists of "citation classics" in the field. We analyzed the characteristics of these articles to determine what qualities make an article important to this subspecialty of orthopaedic surgery. Web of Knowledge was searched on March 7, 2011, using the term "arthroscopy" for citations to articles related to arthroscopy in 61 orthopaedic journals and using the all-database function. Each of the 61 orthopaedic journals was searched separately for arthroscopy-related articles to determine the 25 most cited articles. An all-database search for arthroscopy-related articles was carried out and compared with a journal-by-journal search. Each article was reviewed for basic information including the type of article, authorship, institution, country, publishing journal, and year published. The number of citations ranged from 189 to 567 in a journal-by-journal search and from 214 to 1,869 in an all-database search. The 25 most cited articles on arthroscopic surgery were published in 11 journals: 8 orthopaedic journals and 3 journals from other specialties. The most cited article in arthroscopic orthopaedic surgery was published in The New England Journal of Medicine, which was not previously identified by a journal-by-journal search. An all-database search in Web of Knowledge gives a more in-depth methodology of determining the true citation ranking of articles. Among the top 25 most cited articles, autologous chondrocyte implantation/transplantation is currently the most cited and most popular topic in arthroscopic

    Blundell, Arthur G

    2007-03-01

    Foresters are currently confronted with a new challenge. For the first time a commonly traded timber species has been listed on the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). At the 12th Conference of the Parties in November 2002, countries voted 68 to 30 to place the premier timber species of Latin America, big-leaf mahogany (Swietenia macrophylla King [Meliaceae]), on CITES Appendix II. Under Appendix II regulations, trade in mahogany requires that exporting countries verify that each shipment was legally obtained and that its harvest was non-detrimental to the survival of the species. Unfortunately, implementation has been weak, in part because countries have yet to develop a common, pragmatic, cost-effective system to make the legal and non-detriment findings. This paper recommends what such a system might include.

    To characterize the 100 most-cited articles in medical imaging. The Scopus database was searched for citations to articles published in any of the 116 journals in the subject category "radiology, nuclear medicine, and medical imaging" at the Institute of Science Information Web of Science that the authors termed "imaging literature." Using the Scopus database, two authors searched electronic and print versions of these journals to determine the 100 most-cited articles. The following data were collected for each article: journal name, journal impact factor, number of authors, publication year, country in which the study was performed, department of all authors, article type, imaging modality, grant funding, and clinical subspecialty. Statistical and/or mathematic, magnetic resonance (MR) imaging technique, image processing and/or analysis and computer science, new imaging technique, and basic science articles were considered "preclinical." Using the Pearson correlation coefficient, the authors examined the relationship between journal impact factor and the number of top 100 cited articles included in the list. Most studies were classified as preclinical (n = 75). Fifty-eight of the 100 articles were neuroradiology articles. NeuroImage had the most highly cited articles (n = 22). MR imaging was the most commonly studied imaging modality (n = 69). The authors of 51 articles were from radiology departments. Most articles were published from 1990 to the present (n = 87). There was a statistically significant positive correlation between journal impact factor and the number of top 100 cited articles (r = 0.46, P < .001). Preclinical articles, primarily in the field of neurologic MR imaging, were highly represented in the top 100 cited articles in the medical imaging literature. © RSNA, 2013.

    Research has tremendously contributed to the developments in both practical and fundamental aspects of limb prosthetics. These advancements are reflected in scientific articles, particularly in the most cited papers. This article aimed to identify the 100 top-cited articles in the field of limb prosthetics and to investigate their main characteristics. Articles related to the field of limb prosthetics and published in the Web of Knowledge database of the Institute for Scientific Information (ISI) from the period of 1980 to 2012. The 100 most cited articles in limb prosthetics were selected based on the citation index report. All types of articles except for proceedings and letters were included in the study. The study design and level of evidence were determined using Sackett's initial rules of evidence. The level of evidence was categorized either as a systematic review or meta-analysis, randomized controlled trial, cohort study, case-control study, case series, expert opinion, or design and development. The top cited articles in prosthetics were published from 1980 to 2012 with a citation range of 11 to 90 times since publication. The mean citation rate was 24.43 (SD 16.7) times. Eighty-four percent of the articles were original publications and were most commonly prospective (76%) and case series studies (67%) that used human subjects (96%) providing level 4 evidence. Among the various fields, rehabilitation (47%), orthopedics (29%), and sport sciences (28%) were the most common fields of study. The study established that studies conducted in North America and were written in English had the highest citations. Top cited articles primarily dealt with lower limb prosthetics, specifically, on transtibial and transradial prosthetic limbs. Majority of the articles were experimental studies.

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

    Examination of top-cited articles is a tool that can help to identify and monitor outstanding scientific researches and landmark papers. We aimed to identify the 100 most cited published papers in peer-reviewed biomedical journals in the field of digestive diseases and to examine their characteristics. The Web of Science (including Science Citation Index) was searched for the most cited papers related to digestive diseases, published from 1955 to the present. The top 100 most cited articles were identified. The number of citations, countries, and institutions of origin, year of publication, study design, topic, and levels of evidence of the articles were noted and analyzed. The most top-cited articles had a mean of 1375 citations. These articles were published between 1978 and 2009 in 29 high-impact journals, with the New England Journal of Medicine (n = 22) topping the list. Of the 100 articles, 34 were clinical studies, 15 were review articles, and 34 were concerned basic science. These articles came from 18 countries, with the USA contributing most of the top-cited articles (n = 53). Eighty-seven institutions produced these 100 top-cited articles, led by the University of Barcelona (n = 4). Seven persons authored two or more of these top-cited articles. The mostly represented specialty was gastrointestinal oncology (n = 49). Our study can give a historical perspective on the scientific progress of digestive diseases, as well as allow for recognition of most important advances in this area and provide useful information to guide future researches. © 2015 Journal of Gastroenterology and Hepatology Foundation and Wiley Publishing Asia Pty Ltd.

  7. Are medical articles highlighting detailed statistics more cited?

    2015-06-01

    Full Text Available When conducting a literature review, it is natural to search for articles and read their abstracts in order to select papers to read fully. Hence, informative abstracts are important to ensure that research is read. The description of a paper's methods may help to give confidence that a study is of high quality. This article assesses whether medical articles that mention three statistical methods, each of which is arguably indicative of a more detailed statistical analysis than average, are more highly cited. The results show that medical articles mentioning Bonferroni corrections, bootstrapping and effect size tend to be 7%, 8% and 15% more highly ranked for citations than average, respectively. Although this is consistent with the hypothesis that mentioning more detailed statistical techniques generate more highly cited research, these techniques may also tend to be used in more highly cited areas of Medicine.

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

    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.

    1993-02-01

    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.

    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.

    The study aims to illustrate the impact of Spanish research in clinical decision making. To this end, we analysed the characteristics of the most significant Spanish publications cited in clinical practice guidelines (CPG) on mental health. We conducted a descriptive qualitative study on the characteristics of ten articles cited in Spanish CPG on mental health, and selected for their "scientific quality". We analysed the content of the articles on the basis of the following characteristics: topics, study design, research centres, scientific and practical relevance, type of funding, and area or influence of the reference to the content of the guidelines. Among the noteworthy studies, some basic science studies, which have examined the establishment of genetic associations in the pathogenesis of mental illness are included, and others on the effectiveness of educational interventions. The content of those latter had more influence on the GPC, because they were cited in the summary of the scientific evidence or in the recommendations. Some of the outstanding features in the selected articles are the sophisticated designs (experimental or analytical), and the number of study centres, especially in international collaborations. Debate or refutation of previous findings on controversial issues may have also contributed to the extensive citation of work. The inclusion of studies in the CPG is not a sufficient condition of "quality", but their description can be instructive for the design of future research or publications.

    Jouvet, Lionel; Conde, Dalia Amor; Stärk, Johanna

    The illegal international wildlife trade is a major threat to biodiversity by directly diminishing populations numbers. Additional threats are the potential introduction of invasive species and the spread of diseases, either due to intentional or accidental releases of confiscated animals...... of species under CITES is mainly based on the species extinction risk, on which export quotas are determined. Here we analyzed which species listed in CITES overlap with those listed as threated by human extraction under the IUCN Red List. Additionally, we assessed for how many species it is possible......, which can flag CITES and IUCN Specialist Groups (SSC) of possible important overlaps to consider. Moreover, with the connection to animal life history databases, and experts from the SSC it will be possible to obtain better data to estimate quotas. These will certainly promote a closer collaboration...

    into the maps as relationships become overt. Finally, the study discusses how high publication activity influences mapping results considerably. To counter this effect, we demonstrate the appropriateness of correcting data for main effects by use of an asymmetric proximity measure of odds ratios....... of the author's dual roles of citing and being cited in a reference network. We model a set of 31 authors and compare the results to a recent author co-citation study of Information Science. We find that multidimensional unfolding is a reliable and insightful technique for modelling authors' citing and cited...... dimensions simultaneously. The common space of citing and cited positions exemplify that some authors have substantial discrepancies between their citing behaviour and the way their works are used by peers in the set. Further, modelling mutual relationships as asymmetric brings more accuracy and nuances...

    2017-08-12

    To identify the 100 top-cited articles published in journals dedicated to acupuncture & moxibustion research and analyze their characteristics so as to explore its academic state. All the articles were collected from the China National Knowledge Infrastructure (CNKI, January 1, 1943 to December 25, 2016), Web of Science (January 1, 1950 to December 25, 2016), WANFANG Database (January 1, 1998 to December 25, 2016). The top-cited articles were selected and analyzed with regard to publication year, number of citations, journals, authors, country or region, institution, title, type and subject. One hundred and two articles were included, 43 Chinese articles and 59 English articles, cited between 146 and 505 times, and the average number of citation was 222. Of the 10 articles cited in the top 10, China and the United States had 4 articles respectively. These articles appeared in 44 journals, 24 articles in Chinese Acupuncture & Moxibustion , followed by 8 articles in Pain . All the articles belonged to 9 countries and regions, 47 articles from mainland China and 21 articles from the United State. Of the 14 institutes whose article number ranked at top 10, Tianjing University of TCM had 8 articles. The first authors published most papers were professor HAN Jisheng and Cherkin DC, each of whom had 4 articles. All the articles were categorized into basic science article (n=27), clinical research (n=33) and literature study (n=42). The main topics were pain diseases and brain impairment. This analysis of high cited articles reveals academic trends and directions of acupuncture and moxibustion. Acupuncture and moxibustion are more and more recognized by mainstream medicine in the world, but the academic dominance of China has been increasingly challenged by the United States, Germany and so on.

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

    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.

  2. Variations of CITED2 are associated with congenital heart disease (CHD in Chinese population.

    Full Text Available CITED2 was identified as a cardiac transcription factor which is essential to the heart development. Cited2-deficient mice showed cardiac malformations, adrenal agenesis and neural crest defects. To explore the potential impact of mutations in CITED2 on congenital heart disease (CHD in humans, we screened the coding region of CITED2 in a total of 700 Chinese people with congenital heart disease and 250 healthy individuals as controls. We found five potential disease-causing mutations, p.P140S, p.S183L, p.S196G, p.Ser161delAGC and p. Ser192_Gly193delAGCGGC. Two mammalian two-hybrid assays showed that the last four mutations significantly affected the interaction between p300CH1 and CITED2 or HIF1A. Further studies showed that four CITED2 mutations recovered the promoter activity of VEGF by decreasing its competitiveness with HIF1A for binding to p300CH1 and three mutations decreased the consociation of TFAP2C and CITED2 in the transactivation of PITX2C. Both VEGF and PITX2C play very important roles in cardiac development. In conclusion, we demonstrated that CITED2 has a potential causative impact on congenital heart disease.

    The number of citations an article receives is an important indication of its impact and contribution to the clinical world. There is a paucity of literature concerning top article citations in cardiology. The main objective of this investigation was to bridge this gap and to provide readers a practical guide in evaluating the cardiovascular literature. Scopus Library database was searched to determine the citations of all published cardiovascular articles. One hundred two journals were included in our investigation under the Institute of Science Information Web of Science subject category "cardiology, cardiovascular, and heart." We did not apply any time or study-type restriction in our search. The top 100 cited articles were selected and analyzed by 2 independent investigators. The journal with the highest number of top 100 cited articles was Circulation with 36, followed by 28 in the European Heart Journal. A statistically significant association was found between the journal impact factor and the number of top 100 cited articles (p journals such as The Lancet (n = 4) and The New England Journal of Medicine (n = 1) contributed only 5 articles to the list despite their extremely high impact factors. In conclusion, our analysis provides an insight on the citation frequency of top cited articles published in cardiovascular medicine to help recognize the quality of the works, discoveries, and the trends steering cardiology.

    2006-01-01

    Background A minority of scientific journals publishes the majority of scientific papers and receives the majority of citations. The extent of concentration of the most influential articles is less well known. Methods/Principal Findings The 100 most-cited papers in the last decade in each of 21 scientific fields were analyzed; fields were considered as ecosystems and their “species” (journal) diversity was evaluated. Only 9% of journals in Journal Citation Reports had published at least one such paper. Among this 9%, half of them had published only one such paper. The number of journals that had published a larger number of most-cited papers decreased exponentially according to a Lotka law. Except for three scientific fields, six journals accounted for 53 to 94 of the 100 most-cited papers in their field. With increasing average number of citations per paper (citation density) in a scientific field, concentration of the most-cited papers in a few journals became even more prominent (pjournals available in a scientific field. Multidisciplinary journals accounted for 24% of all most-cited papers, with large variability across fields. The concentration of most-cited papers in multidisciplinary journals was most prominent in fields with high citation density (correlation coefficient 0.70, pjournals had published fewer than eight of the 100 most-cited papers in eight scientific fields (none in two fields). Journals concentrating most-cited original articles often differed from those concentrating most-cited reviews. The concentration of the most-influential papers was stronger than the already prominent concentration of papers published and citations received. Conclusions Despite a plethora of available journals, the most influential papers are extremely concentrated in few journals, especially in fields with high citation density. Existing multidisciplinary journals publish selectively most-cited papers from fields with high citation density. PMID:17183679

    Background: Fatigue is an important aging mechanism in RPV and it must be contained to aging management working range. Purpose: In order to ensure the safety operation of nuclear power plants, as extension of RPV service time, it is necessary to assess the fatigue damage caused by actual operation transient. Methods: Based on monitoring data of actual operation during the past eleven years, refer to design transient, the statistic analysis for types and occurrence times of actual transient is carried out, at the same time, every transients are combined as different operation cycles and the temperature field and stress field of typical components are analyzed by FEM. Results: Based on these information, fatigue analysis and assessment are finished, if later-actual transients are similar with the previous transients, the calculation result shows that the ratio between maximum of cumulative usage factors and design calculation value is 0.4967 the design transients is conservative. Conclusions: Fatigue status of RPV could be assessed and traced quickly through fatigue status assessment method in this paper based on actual operational transient and assessment result would be a good reference for RPV aging management.

    2016-01-01

    Since 1993, The Knee Society has presented three annual awards recognizing the best research papers presented at the annual meetings. To date, no quantitative evaluation has determined whether the selection process identifies the most meritorious papers based on subsequent citations. In the absence of validation of this process, it is unclear whether the journal readership should view the award-winning papers as those with potentially greater impact for the specialty. (1) Are award papers cited both more than nonaward papers published in the same Knee Society proceedings issue of CORR(®) and more than all other knee research papers published in all issues of CORR(®) during any given year? (2) Does the award selection process identify potentially highly influential knee research? Subsequent citations for each award and nonaward paper published in The Knee Society proceedings issue for 2002 to 2008 were determined using the SCOPUS citation index. The citations for all papers on knee surgery published in CORR(®) during the same years were also determined. Mean citations for an award paper were statistically greater than for a nonaward paper: 86 (SD 95; median 55; 95% confidence interval [CI] of the mean, 44-128) versus 33 (SD 30; median 24; 95% CI of the mean, 28-37; p papers was also higher than for all other knee research papers published in nonproceedings issues of CORR(®): 86 (SD 95; median 55; 95% CI of the mean, 44-128) versus 30 (SD 31; median 20; 95% CI for the mean, 25-35; p papers were in the top five cited papers from the proceedings issue for the respective year versus 24 of the 190 (12.6%) of the nonaward papers (difference in the percentages is 41.9% and the 95% CI for the risk difference is 20.6%-63.3%; p paper was the most cited knee paper published in CORR(®). The selection process for The Knee Society scientific awards identifies potentially influential papers that are likely to be highly cited in future research articles about the knee. The

    The international wildlife trade is a key threat to biodiversity. Temporal genetic marketplace monitoring can determine if wildlife trade regulation efforts such as the Convention on International Trade in Endangered Species (CITES) are succeeding. Protected under CITES effective 1997, sturgeons and paddlefishes, the producers of black caviar, are flagship CITES species. We test whether CITES has limited the amount of fraudulent black caviar reaching the marketplace. Using mitochondrial DNA-based methods, we compare mislabeling in caviar and meat purchased in the New York City area pre and post CITES listing. Our recent sampling of this market reveals a decrease in mislabeled caviar (2006-2008; 10%; n = 90) compared to pre-CITES implementation (1995-1996; 19%; n = 95). Mislabeled caviar was found only in online purchase (n = 49 online/41 retail). Stricter controls on importing and exporting as per CITES policies may be having a positive conservation effect by limiting the amount of fraudulent caviar reaching the marketplace. Sturgeons and paddlefishes remain a conservation priority, however, due to continued overfishing and habitat degradation. Other marine and aquatic species stand to benefit from the international trade regulation that can result from CITES listing.

  15. Decay of references to Web sites in articles published in general medical journals: mainstream vs small journals.

    Science.gov (United States)

    Habibzadeh, P

    2013-01-01

    Over the last decade, Web sites (URLs) have been increasingly cited in scientific articles. However, the contents of the page of interest may change over the time. To investigate the trend of citation to URLs in five general medical journals since January 2006 to June 2013 and to compare the trends in mainstream journals with small journals. References of all original articles and review articles published between January 2006 and June 2013 in three regional journals - Archives of Iranian Medicine (AIM), Eastern Mediterranean Health Journal (EMHJ), and Journal of Postgraduate Medical Institute (JPMI) - and two mainstream journals - The Lancet and British Medical Journal (BMJ) - were reviewed. The references were checked to determine the frequency of citation to URLs as well as the rate of accessibility of the URLs cited. A total of 2822 articles was studied. Since January 2006 onward, the number of citations to URLs increased in the journals (doubling time ranged from 4.2 years in EMHJ to 13.9 years in AIM). Overall, the percentage of articles citing at least one URL has increased from 24% in 2006 to 48.5% in 2013. Accessibility to URLs decayed as the references got old (half life ranged from 2.2 years in EMHJ to 5.3 years in BMJ). The ratio of citation to URLs in the studied mainstream journals, as well as the ratio of URLs accessible were significantly (pjournals. URLs are increasingly cited, but their contents decay with time. The trend of citing and decaying URLs are different in mainstream journals compared to small medical journals. Decay of URL contents would jeopardize the accuracy of the references and thus, the body of evidence. One way to tackle this important obstacle is to archive URLs permanently.

    There are many characteristics can be used to identify a document which cover characteristics of the documents, cited documents, and citing documents This research explored the inherent structure of a document collection as one of main components of information retrieval system. The characteristics examined are: descriptors, references (cited documents), and citations (citing documents). Three independent variables were studied: co-descriptor, bibliographic coupling, and co-citation. A test collection was constructed by searching on a single descriptor i nformation retrieval i n the CD-ROM version of Education Resource Information Clearinghouse (ERIC), covering the period 1981 through 1985. Descriptors were extracted from ERIC; cited and citing documents associated with the test collection were derived from Social Sciences Citation Index (SSCI), covering the period 1981 through 1990. Three hypothesis were tested in this study, that are: (1) the higher the frequency of co-descriptors between documents, the higher the frequencies of their bibliographic coupling and co-citation; (2) the higher the frequency of bibliographic coupling between documents, the higher the frequencies of their co-citation and co-descriptors; and (3) the higher the frequency of co-citation between documents, the higher the frequencies of their co-descriptors and bibliographic coupling. The results showed that all of three hypothesis are supported statistically and there is a significant linear relationship among the observed variables. It is mean that there is a significant relationship among descriptors, references, and citation, so that it can be used to construct the inherent structure of document collection in order to improve information retrieval system performance

  18. Concentration of the most-cited papers in the scientific literature: analysis of journal ecosystems.

    2006-12-20

    A minority of scientific journals publishes the majority of scientific papers and receives the majority of citations. The extent of concentration of the most influential articles is less well known. The 100 most-cited papers in the last decade in each of 21 scientific fields were analyzed; fields were considered as ecosystems and their "species" (journal) diversity was evaluated. Only 9% of journals in Journal Citation Reports had published at least one such paper. Among this 9%, half of them had published only one such paper. The number of journals that had published a larger number of most-cited papers decreased exponentially according to a Lotka law. Except for three scientific fields, six journals accounted for 53 to 94 of the 100 most-cited papers in their field. With increasing average number of citations per paper (citation density) in a scientific field, concentration of the most-cited papers in a few journals became even more prominent (ppapers published or number of journals available in a scientific field. Multidisciplinary journals accounted for 24% of all most-cited papers, with large variability across fields. The concentration of most-cited papers in multidisciplinary journals was most prominent in fields with high citation density (correlation coefficient 0.70, ppapers in eight scientific fields (none in two fields). Journals concentrating most-cited original articles often differed from those concentrating most-cited reviews. The concentration of the most-influential papers was stronger than the already prominent concentration of papers published and citations received. Despite a plethora of available journals, the most influential papers are extremely concentrated in few journals, especially in fields with high citation density. Existing multidisciplinary journals publish selectively most-cited papers from fields with high citation density.

    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 articles, the most downloaded articles more frequently originated from the UK (8.7% vs 5.0%, p articles (46.0% vs 39.4%, p 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.

    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.

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

  2. Testing the effectiveness of an international conservation agreement: marketplace forensics and CITES caviar trade regulation.

    Full Text Available BACKGROUND: The international wildlife trade is a key threat to biodiversity. Temporal genetic marketplace monitoring can determine if wildlife trade regulation efforts such as the Convention on International Trade in Endangered Species (CITES are succeeding. Protected under CITES effective 1997, sturgeons and paddlefishes, the producers of black caviar, are flagship CITES species. METHODOLOGY/PRINCIPAL FINDINGS: We test whether CITES has limited the amount of fraudulent black caviar reaching the marketplace. Using mitochondrial DNA-based methods, we compare mislabeling in caviar and meat purchased in the New York City area pre and post CITES listing. Our recent sampling of this market reveals a decrease in mislabeled caviar (2006-2008; 10%; n = 90 compared to pre-CITES implementation (1995-1996; 19%; n = 95. Mislabeled caviar was found only in online purchase (n = 49 online/41 retail. CONCLUSIONS/SIGNIFICANCE: Stricter controls on importing and exporting as per CITES policies may be having a positive conservation effect by limiting the amount of fraudulent caviar reaching the marketplace. Sturgeons and paddlefishes remain a conservation priority, however, due to continued overfishing and habitat degradation. Other marine and aquatic species stand to benefit from the international trade regulation that can result from CITES listing.

    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.

  6. Is the Einstein de Sitter model actually ruled out?

    The standard model for cosmology which is now strongly favored is a flat model, dominated by a vacuum density term. However, the actual direct evidences for such term are limited, essentially based on the supernova probe, i.e. based on a standard candle hypothesis. Here I would like to point out that contrary to the general belief there is room for an Einstein de Sitter universe. Actually several independent measurements, not based on stellar reference, pointed towards a high matter density Universe, weakening the need for a cosmological constant

    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 .

    Our purpose was to identify the top 100 cited articles, which focused on CT colonography (CTC). This list could then be analysed to establish trends in CTC research while also identifying common characteristics of highly cited works. Web of Science search was used to create a database of scientific journals using our search terms. A total of 10,597 articles were returned from this search. Articles were included if they focused on diagnostic imaging, imaging technique, cost-effectiveness analysis, clinical use, patient preference or trends in CTC. Articles were ranked by citation count and screened by two attending radiologists. The following information was collected from each article: database citations, citations per year, year published, journal, authors, department affiliation, study type and design, statistical analysis, sample size, modality and topic. Citations for the top 100 articles ranged from 73 to 1179, and citations per year ranged from 4.5 to 84.21. Articles were published across 22 journals, most commonly Radiology (n = 37) and American Journal of Roentgenology (n = 19). Authors contributed from 1 to 20 articles. 19% of first authors were affiliated with a department other than radiology. Of the 100 articles, the most common topics were imaging technique (n = 40), diagnostic utility of imaging (n = 28) and clinical uses (n = 18). Our study provides intellectual milestones in CTC research, reflecting on the characteristics and quality of published literature. This work also provides the most influential references related to CTC and serves as a guide to the features of a citable paper in this field.

    Nowadays, publishing highly-cited papers is important for researchers and editors. In this evidence-based study, the factors influencing the citability of published papers in the field of medicine have been identified. 200 papers indexed in Scopus (in two groups: highly-cited and lowly-cited) with 100 papers in each were studied. Needed data were manually collected with a researcher-made checklist. Data analysis was done in SPSS using descriptive and inferential statistics. Variables such as journal IF, journal rank, journal subject quartile, the first/corresponding author's h-index, the number of documents produced by the first/corresponding author, SJR and SNIP had significantly positive correlation with paper citability (ppaper age, paper type, the number of references, the number of authors, indexing institute and journal kind had not any relationship with paper citability (p> .05). the factors affecting the citability are among indicators relating to authors, publishing journals and published papers. Determining the extent to which these factors influence the citability of a paper needs further large-scaled research. Authors and editors searching for high-citedness should consider these factors when authoring and publishing papers.

    The number of citations that an article has received reflects its impact on the scientific community. The purpose of our study was to identify and characterize the 51 most-cited articles in pediatric imaging. Based on the database of Journal Citation Reports, we selected 350 journals that were considered as potential outlets for pediatric imaging articles. The Web of Science search tools were used to identify the most-cited articles relevant to pediatric imaging within the selected journals. The 51 most-cited articles in pediatric imaging were published between 1952 and 2011, with 1980- 1989 and 2000-2009 producing 15 articles, each. The number of citations ranged from 576-124 and the number of annual citations ranged from 49.05-2.56. The majority of articles were published in pediatric and related journals (n=26), originated in the United States (n=23), were original articles (n=45), used MRI as imaging modality (n=27), and were concerned with the subspecialty of brain (n=34). University College London School of Medicine (n=6) and School of Medicine University of California (n=4) were the leading institutions and Reynolds EO (n=7) was the most voluminous author. Our study presents a detailed list and an analysis of the most-cited articles in the field of pediatric imaging, which provides an insight into historical developments and allows for recognition of the important advances in this field.

    Identification of highly cited articles based on the h-index and its properties is important for the evaluation of the past, present, and future of any research discipline. In this study, we aimed to identify the h-classic articles in orthodontics. One search on the Web of Science identified all articles from 2000 to 2015 in the 89 journals indexed by the 2015 InCites Journal Citation Reports in the scientific area "dentistry, oral surgery, and medicine." A second search was performed in the Web of Science using all mesh terms related to orthodontics. Then, we applied the h-classic method to select the recent articles with the greatest scientific impact in orthodontics. Eighty articles were considered as h-classic articles. They were published in 20 of the 89 dental journals of the 2015 InCites Journal Citation Reports list. Only 36 articles appeared in orthodontic journals: 23 in the American Journal of Orthodontics & Dentofacial Orthopedics (28.8%), 7 in The Angle Orthodontist (8.8%), and 6 in European Journal of Orthodontics (7.5%). Thirty-eight articles originated from Europe, 28 from the Americas, and 14 from the Middle East and Asia. More than half of fundamental orthodontic research is published in nonorthodontic journals showing that our field is currently limited, and interactions with other research fields should be sought to increase orthodontic research importance and appeal.

    To identify the 100 top-cited articles published in orthodontics journals and to analyze their characteristics to investigate the achievement and development of orthodontics research in past decades. The Institute for Scientific Information Web of Knowledge Database and the 2011 Journal Citation Report Science Editions were used to retrieve the 100 top-cited articles published in orthodontics journals since 1975. Some basic information was collected by the Analyze Tool on the Web of Science, including citation time, publication title, journal name, publication year, and country and institution of origin. A further study was then performed to determine authorship, article type, field of study, study design, and level of evidence. The 100 target articles were retrieved from three journals: American Journal of Orthodontics and Dentofacial Orthopedics (n  =  74), The Angle Orthodontist (n = 15), and European Journal of Orthodontics (n  =  11). Since 1975, the articles cited 89 to 545 times mainly originated from the United States, and the overwhelming majority of articles were clinical. The most common study design was case series; 40 articles were classified as level IV and 12 as level V evidence. The 100 top-cited articles in orthodontics are generally old articles, rarely possessing high-level evidence.

  17. Estimating Riparian and Agricultural Actual Evapotranspiration by Reference Evapotranspiration and MODIS Enhanced Vegetation Index

    Full Text Available Dryland river basins frequently support both irrigated agriculture and riparian vegetation and remote sensing methods are needed to monitor water use by both crops and natural vegetation in irrigation districts. We developed an algorithm for estimating actual evapotranspiration (ETa based on the Enhanced Vegetation Index (EVI from the Moderate Resolution Imaging Spectrometer (MODIS sensor on the EOS-1 Terra satellite and locally-derived measurements of reference crop ET (ETo. The algorithm was calibrated with five years of ETa data from three eddy covariance flux towers set in riparian plant associations on the upper San Pedro River, Arizona, supplemented with ETa data for alfalfa and cotton from the literature. The algorithm was based on an equation of the form ETa = ETo [a(1 − e−bEVI − c], where the term (1 − e−bEVI is derived from the Beer-Lambert Law to express light absorption by a canopy, with EVI replacing leaf area index as an estimate of the density of light-absorbing units. The resulting algorithm capably predicted ETa across riparian plants and crops (r2 = 0.73. It was then tested against water balance data for five irrigation districts and flux tower data for two riparian zones for which season-long or multi-year ETa data were available. Predictions were within 10% of measured results in each case, with a non-significant (P = 0.89 difference between mean measured and modeled ETa of 5.4% over all validation sites. Validation and calibration data sets were combined to present a final predictive equation for application across crops and riparian plant associations for monitoring individual irrigation districts or for conducting global water use assessments of mixed agricultural and riparian biomes.

  19. Structural and Functional Diversity of Plant Virus 3'-Cap-Independent Translation Enhancers (3'-CITEs).

    Science.gov (United States)

    Truniger, Verónica; Miras, Manuel; Aranda, Miguel A

    2017-01-01

    Most of the positive-strand RNA plant viruses lack the 5'-cap and/or the poly(A)-tail that act synergistically to stimulate canonical translation of cellular mRNAs. However, they have RNA elements in the 5'- or 3'-untranslated regions of their RNAs that are required for their cap-independent translation. Cap-independent translation enhancers (CITEs) have been identified in the genomic 3'-end of viruses belonging to the family Tombusviridae and the genus Luteovirus . Seven classes of 3'-CITEs have been described to date based on their different RNA structures. They generally control the efficient formation of the translation initiation complex by varying mechanisms. Some 3'-CITEs bind eukaryotic translation initiation factors, others ribosomal subunits, bridging these to the 5'-end by different mechanisms, often long-distance RNA-RNA interactions. As previously proposed and recently found in one case in nature, 3'-CITEs are functionally independent elements that are transferable through recombination between viral genomes, leading to potential advantages for virus multiplication. In this review, the knowledge on 3'-CITEs and their functioning is updated. We also suggest that there is local structural conservation in the regions interacting with eIF4E of 3'-CITEs belonging to different classes.

    The highest cited papers published in a journal provide a snapshot of the clinical practice and research in that specialty and/or region. The aim of this study was to determine the highest cited papers published in Neurology India and analyze their attributes. This study was a citation analysis of all papers published in Neurology India since online archiving commenced in 1993. All papers published in Neurology India between the years 1993-2014 were listed. The number of times each paper had been cited up till the time of performing this study was determined by performing a Google Scholar search. Published papers were then ranked on the basis of total times cited since publication and the annual citation rate. Statistical Techniques: Simple counts and percentages were used to report most results. The mean citations received by papers in various categories were compared using the Student's t-test or a one-way analysis of variance, as appropriate. All analyses were carried out on SAS University Edition (SAS/STAT®, SAS Institute Inc, NC, USA) and graphs were generated on MS Excel 2016. The top papers on the total citations and annual citation rate rank lists pertained to basic neuroscience research. The highest cited paper overall had received 139 citations. About a quarter of the papers published had never been cited at all. The major themes represented were vascular diseases and infections. The highest cited papers reflect the diseases that are of major concern in India. Certain domains such as trauma, allied neurosciences, and basic neuroscience research were underrepresented.

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

    Purpose  The number of citations that an article has received reflects its impact on a particular research area. The aim of this study was to identify the 100 most-cited articles focused on ultrasound (US) imaging and to analyze the characteristics of these articles. Methods  We determined the 100 most-cited articles on US imaging via the Web of Science database, using the search term. The following parameters were used to analyze the characteristics of the 100 most-cited articles: publication year, journal, journal impact factor, number of citations and annual citations, authors, department, institution, country, type of article, and topic. Results  The number of citations for the 100 most-cited articles ranged from 1849 to 341 (median: 442.0) and the number of annual citations ranged from 108.0 to 8.1 (median: 22.1). The majority of articles were published in 1990 - 1999 (39 %), published in radiology journals (20 %), originated in the United States (45 %), were clinical observation studies (67 %), and dealt with the vessels (35 %). The Department of Internal Medicine at the University of California and the Research Institute of Public Health at the University of Kuopio (n = 4 each) were the leading institutions and Salonen JT and Salonen R (n = 4 each) were the most prolific authors. Conclusion  Our study presents a detailed list and analysis of the 100 most-cited US articles, which provides a unique insight into the historical development in this field. © Georg Thieme Verlag KG Stuttgart · New York.

    To analyze the highly cited malaria papers published in Chinese journals from 2006 to 2013, so as to provide the evidence for formulating the plan of selecting topics to the journal editors. The published articles related to malaria included in CNKI and Wanfang medical network from 2006 to 2013 were collected, and the highly cited papers were selected according to the citation frequency calculated by Price's formula. Then the characteristics of the highly cited papers were analyzed. From 2006 to 2013, a total of 1 976 published papers related to malaria were searched in Chinese journals and 98 papers of them were selected as highly cited papers. In the highly cited papers, 18 papers were published in China Tropical Medicine , and 16 and 15 papers were published in Chinese Journal of Parasitology and Parasitic Diseases and Chinese Journal of Schistosomiasis Control , respectively; and original articles accounted for 42.86%; the first authors of these papers were from 44 institutions, and 40.91% of them were from centers for disease control and prevention (CDCs); a percentage of 22.45% of the highly cited papers received fund programs, and most of them were national or provincial funds. The research hotspots were focused on the epidemiology and control, and epidemic situation of malaria. The highly cited papers related to malaria are mainly from CDCs and research institutions, and the related journals could use this information to chose topics and solicit contributions to improve their influence.

    The field of bioethics is constantly evolving. To investigate trends in the field of bioethics, we conducted a quantitative analysis of the top-cited articles in bioethical journals over the past 40 years. Retrospective quantitative study of the 20 most cited bioethics articles published each year from 1975 to 2014 were conducted. Article samples were selected from a list of the most relevant 100 journals in the field of bioethics. In total, 800 top-cited articles between 1975 and 2014 in the domain of bioethics were retrieved and analysed. More than half of them were composed by single authors, but multiauthorship became more prevalent with time. The majority (84.5%) of these highly cited articles originated from the USA (65.3%), UK or Canada, though the proportion of other countries increased in recent years. Almost half (44.6%) of the highly cited articles belonged to the subfield of clinical ethics , but other subfields such as research ethics , public health ethics and neuroethics became more prominent. Overall, the distribution of Thesaurus keywords and subfields became more diverse over time, and the number of journals publishing top-cited articles doubled. Furthermore, the empirical ethics approach increased over time in our sample of top-cited articles. In sum, the forefront of bioethics is getting more diversified, collaborative and international. The presumed 'mainstream' becomes less dominant over time, as more highly cited articles come from new subfields, discuss new topics, use more Bioethics Thesaurus keywords, more authors participate and more countries other than the USA contribute to bioethics journals.

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

    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.

    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.

    Stroke is a disastrous disease and a major health burden worldwide, especially in Korea. Hemorrhagic stroke (HS) accounts for approximately 20% of all the types of strokes. It is important to be able to evaluate stroke diagnoses and evolving treatments. We aimed to identify the top-100 cited articles and assess a paradigm shift that occurred in the field of HS. We searched all articles that had been cited more than 100 times using the Web of Science citation search tool during January 2016. Among a total of 2,651 articles, we identified the top-100 cited articles on HS. The number of citations for the articles analyzed in this study ranged from 1,746 to 211, and the number of annual citations ranged from 125.6 to 5.5. Most of the articles that were published in Stroke (35%) and Journal of Neurosurgery (22%), originated in the United States (n = 56), were original articles (64%), and dealt with the natural history or etiology (n = 37) and vasospasm in subarachnoid hemorrhage (n = 8). We analyzed the top-100 cited articles in the field of HS based on citation rates. The results provide a unique perspective on historical and academic developments in this field. © 2017 S.

    Aberrant epidermal growth factor (EGF) receptor (EGFR) signaling contributes to neoplastic initiation and progression in lung. Mutated EGFR has become as an important therapeutic target in lung cancer, whereas targeted treatment is not available for wild-type EGFR or its ligands. In this study, we found that heparin-binding (HB)-EGF, a member of the EGF family, was highly expressed in a subset of lung cancer, proliferation of which was dependent on HB-EGF signaling. Silencing of HB-EGF with RNA interference inhibited cell cycle progression in lung cancer cells. We observed that, upon HB-EGF induction, CITED4 was induced through a signal transducer and activator of transcription 3 (STAT3)-dependent pathway, regulating cell proliferation. CITED4 interacted with MYC and potentiated MYC-mediated transactivation of the CCND1 promoter, leading to cell cycle progression. Correlation analysis revealed that HB-EGF and CITED4 were significantly positively associated in primary lung tumors, and expression of HB-EGF predicted a poor survival outcome in patients. In vitro and in vivo experiments revealed that pharmacological inhibition of HB-EGF with CRM197 significantly attenuated tumor cell growth. Thus, CITED4 functions as a molecular switch in HB-EGF-induced growth control, and HB-EGF provides a novel therapeutic target for lung cancer intervention.

    2017-01-01

    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.

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

    2014-03-01

    Access to scientific knowledge in the context of CITES is a crucial issue. The effectiveness of the text is indeed largely based on adequate scientific knowledge of CITES species. This is a major challenge: more than 30,000 species and 178 member states are involved. The issue of expertise, however, is not really addressed by the Convention. The question was left to the consideration of the COP. Therefore, the COP has created two ad hoc scientific committees: the Plants Committee and the Animals Committee, conferring upon them an ambitious mandate. The article addresses some important issues at stake which are linked to institutional questions, as well as the mixed record after twenty-five years of practice.

    Ioannidis, John P A

    2010-12-01

    University leaders aim to protect, shape, and promote the missions of their institutions. I evaluated whether top highly cited scientists are likely to occupy these positions. Of the current leaders of 96 U.S. high research activity universities, only 6 presidents or chancellors were found among the 4009 U.S. scientists listed in the ISIHighlyCited.com database. Of the current leaders of 77 UK universities, only 2 vice-chancellors were found among the 483 UK scientists listed in the same database. In a sample of 100 top-cited clinical medicine scientists and 100 top-cited biology and biochemistry scientists, only 1 and 1, respectively, had served at any time as president of a university. Among the leaders of 25 U.S. universities with the highest citation volumes, only 12 had doctoral degrees in life, natural, physical or computer sciences, and 5 of these 12 had a Hirsch citation index m < 1.0. The participation of highly cited scientists in the top leadership of universities is limited. This could have consequences for the research and overall mission of universities.

  3. Pitfalls of CITES Implementation in Nepal: A Policy Gap Analysis

    2012-08-01

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

    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.

    Full Text Available The study analysed the clauses of the integral citations to identify the functional roles of the cited author[1] used by EFL postgraduates. The Systemic Functional Linguistics (SFL was adopted in analysing the clauses qualitatively. A purposeful sampling was utilized in choosing the literature review of 20 PhD theses in Information Technology and Applied Linguistics at a public Malaysian university. In terms of the interpersonal meanings, the cited author functions as a ‘Subject’, a ‘Complement’, and an ‘Adjunct’. For the  experiential meanings, the cited author has functions based on the processes types used in each clause, including an ‘Actor’ and a ‘Goal’ with material processes, a ‘Senser’ and a ‘Phenomenon’ with mental processes, a ‘Sayer’ and a ‘Verbiage’ with verbal processes, a ‘Behaver’ with behavioural processes, a ‘Carrier’, a ‘ Carrier: Possessor’, an ‘Attribute’, a ‘Token’, and a ‘Value’ with relational processes, and an ‘Agent: Attributor’ with causative processes. Other functions related to the Circumstantial under the experiential meanings involved an ‘Agent’, a ‘Location (Place’, a ‘Manner: Comparison’, an ‘Accompaniment’ and a ‘Matter’. Field and tenor affected the role of the cited author; field’s effect was demonstrated by using a higher number of the cited author’s roles in the Applied Linguistics, whereas tenor’s influence was illustrated in assigning similar roles to the cited author in the Applied Linguistics and Information Technology. These results extend the findings of previous studies, help students in using citations in academic writing, and present more outputs about citations that can be employed pedagogically.

    Point-of-care ultrasound (POCUS) has been a rapidly growing and broadly used modality in recent decades. The purpose of this study was to determine how POCUS is incorporated into clinical medicine by analyzing trends of use in the published literature. POCUS-related publications were retrieved from the Web of Science (WoS) database. The search results were ranked according to the number of times an article was cited during three time frames and average annual number of citations. Of the top 100 most cited publications in the four rankings, information regarding the publication journal, publication year, first author's nationality, field of POCUS application, and number of times the article was cited was recorded for trend analysis. A total of 7860 POCUS-related publications were retrieved, and publications related to POCUS increased from 8 in 1990 to 754 in 2016. The top 148 cited publications from the four ranking groups were included in this study. Trauma was the leading application field in which POCUS was studied prior to 2001. After 2004, thorax, cardiovascular, and procedure-guidance were the leading fields in POCUS research. >79% (118/148) of the top-cited publications were conducted by authors in the United States, Italy, and France. The majority of publications were published in critical care medicine and emergency medicine journals. In recent years, publications relating to POCUS have increased. POCUS-related research has mainly been performed in thorax, cardiovascular, and procedure-guidance ultrasonography fields, replacing trauma as the major field in which POCUS was previously studied.

    In patients with atherosclerotic complications of diabetes, impaired neovascularization of ischemic tissue in the myocardium and lower limb limits the ability of these tissues to compensate for poor perfusion. We identified 10 novel insulin-regulated genes, among them Adm, Cited2 and Ctgf, which...... were downregulated in endothelial cells by insulin through FoxO1. CITED2, which was downregulated by insulin by up to 54%, is an important negative regulator of hypoxia-inducible factor (HIF) and impaired HIF signaling is a key mechanism underlying the impairment of angiogenesis in diabetes. Consistent...... with impairment of vascular insulin action, CITED2 was increased in cardiac endothelial cells from mice with diet-induced obesity and from db/db mice and was 3.8-fold higher in arterial tissue from patients with type 2 diabetes than non-diabetic controls.

    CITED2 gene is an important cardiac transcription factor that plays a fundamental role in the formation and development of embryonic cardiovascular. Previous studies have showed that knock-out of CITED2 in mice might result in various cardiac malformations. However, the mechanisms of CITED2 mutation on congenital heart disease (CHD) in Chinese Tibetan population are still poorly understood. In the present study, 187 unrelated Tibetan patients with CHD and 200 unrelated Tibetan healthy controls were screened for variants in the CITED2 gene; we subsequently identified one potential disease-causing mutation p.G143A in a 6-year-old girl with PDA and functional analyses of the mutation were carried out. Our study showed that the novel mutation of CITED2 significantly enhanced the expression activity of vascular endothelial growth factor (VEGF) under the role of co-receptor hypoxia inducible factor 1-aipha (HIF-1A), which is closely related with embryonic cardiac development. As a result, CITED2 gene mutation may play a significant role in the development of pediatric congenital heart disease.

    Full Text Available Most of the positive-strand RNA plant viruses lack the 5′-cap and/or the poly(A-tail that act synergistically to stimulate canonical translation of cellular mRNAs. However, they have RNA elements in the 5′- or 3′-untranslated regions of their RNAs that are required for their cap-independent translation. Cap-independent translation enhancers (CITEs have been identified in the genomic 3′-end of viruses belonging to the family Tombusviridae and the genus Luteovirus. Seven classes of 3′-CITEs have been described to date based on their different RNA structures. They generally control the efficient formation of the translation initiation complex by varying mechanisms. Some 3′-CITEs bind eukaryotic translation initiation factors, others ribosomal subunits, bridging these to the 5′-end by different mechanisms, often long-distance RNA–RNA interactions. As previously proposed and recently found in one case in nature, 3′-CITEs are functionally independent elements that are transferable through recombination between viral genomes, leading to potential advantages for virus multiplication. In this review, the knowledge on 3′-CITEs and their functioning is updated. We also suggest that there is local structural conservation in the regions interacting with eIF4E of 3′-CITEs belonging to different classes.

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

    Science.gov (United States)

    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.

  1. Use of population viability analysis to evaluate CITES trade-management options for threatened marine fishes.

    Curtis, Janelle M R; Vincent, Amanda C J

    2008-10-01

    Achieving multiple conservation objectives can be challenging, particularly under high uncertainty. Having agreed to limit seahorse (Hippocampus) exports to sustainable levels, signatories to the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) were offered the option of a single 10-cm minimum size limit (MSL) as an interim management measure for all Hippocampus species (> or =34). Although diverse stakeholders supported the recommended MSL, its biological and socioeconomic implications were not assessed quantitatively. We combined population viability analysis, model sensitivity analysis, and economic information to evaluate the trade-off between conservation threat to and long-term cumulative income from these exploited marine fishes of high conservation concern. We used the European long-snouted seahorse (Hippocampus guttulatus) as a representative species to compare the performance of MSLs set at alternative biological reference points. Our sensitivity analyses showed that in most of our scenarios, setting the MSL just above size at maturity (9.7 cm in H. guttulatus) would not prevent exploited populations from becoming listed as vulnerable. By contrast, the relative risk of decline and extinction were almost halved--at a cost of only a 5.6% reduction in long-term catches--by increasing the MSL to the size reached after at least one full reproductive season. On the basis of our analysis, a precautionary increase in the MSL could be compatible with sustaining fishers' livelihoods and international trade. Such management tactics that aid species conservation and have minimal effects on long term catch trends may help bolster the case for CITES trade management of other valuable marine fishes.

    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.

    Spinal deformity is a condition that has been recognized for many millennia. There have been major advances in the treatment of spinal deformity in recent years and studies outlining new ideas can inspire others to further advance the speciality. The number of citations a paper receives may indicate the influence of that paper. It is therefore important that we evaluate and analyze the most cited works in our field. The aim of this study is to identify the 100 most cited papers relevant to spinal deformity surgery in the literature. A search through the Thomson Reuters Web of Science™ for citations related to spinal deformity surgery was performed. The number of citations, mean citation number (total number citations/years since publication), journal, authors, year of publication and country of origin of the top 100 papers was recorded. The top 100 papers were cited a combined 17,646 times, ranging from 453 to 112. The majority of papers originated from the United States (71) and were published in 20 different journals. The decade 1990-1999 was the most prolific, with 36 of the 100 papers published during this time. Papers pertaining to the management of scoliosis (49) were the most common. This study identifies the top 100 most cited papers in the field of spinal deformity surgery. While citation is not a specific marker of the scientific quality of a paper, it is a surrogate for the influence a paper has had on the orthopedic community. This list of papers provides an invaluable resource for both those in training and those actively practicing and involved in the further development of spinal deformity surgery.

    The emergence of advanced IT and cloud services has beneficially supported the information-intensive tourism industry, simultaneously caused extreme competitions in attracting customers through building efficient service platforms. On response, numerous nations have implemented cloud platforms to provide value-added sightseeing information and personal intelligent service experiences. Despite these efforts, customers' actual perspectives have yet been sufficiently understood. To bridge the gap, this study attempts to investigate what aspects of tourism cloud services actually delight customers' satisfaction and loyalty. 336 valid survey questionnaire answers were analyzed using structural equation modeling method. The results prove positive impacts of function quality, enjoyment, multiple visual aids, and information quality on customers' satisfaction as well as of enjoyment and satisfaction on use loyalty. The findings hope to provide helpful references of customer use behaviors for enhancing cloud service quality in order to achieve better organizational competitiveness.

    Elsevier’s recently launched citation metric CiteScore enables comprehensive, transparent, and current evaluation of a journal’s performance. For an editorial office, insight into a journal’s impact over time is of great value when making important decisions regarding the journal’s future. A 2016 update of CiteScore index values for Acta Dermatovenerologica Alpina, Pannonica et Adri- atica (Acta Dermatovenerol APA) showed a slight decrease in the CiteScore index value from 1.18 in 2015 to 0.96 in 2016. Acta Dermatovenerol APA can still be considered the principal journal in the field of dermatology and sexually transmitted infections in our region, with almost half of the articles published between 2013 and 2015 cited at least once in 2016. Acta Dermatovenerol APA performed well in both categories listed because it ranked 67th out of 121 journals in the category Dermatology (44th percentile) and 175th out of 250 journals in the category Infectious Diseases (30th percentile).

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

    Parker, John N; Lortie, Christopher; Allesina, Stefano

    2010-10-01

    In science, a relatively small pool of researchers garners a disproportionally large number of citations. Still, very little is known about the social characteristics of highly cited scientists. This is unfortunate as these researchers wield a disproportional impact on their fields, and the study of highly cited scientists can enhance our understanding of the conditions which foster highly cited work, the systematic social inequalities which exist in science, and scientific careers more generally. This study provides information on this understudied subject by examining the social characteristics and opinions of the 0.1% most cited environmental scientists and ecologists. Overall, the social characteristics of these researchers tend to reflect broader patterns of inequality in the global scientific community. However, while the social characteristics of these researchers mirror those of other scientific elites in important ways, they differ in others, revealing findings which are both novel and surprising, perhaps indicating multiple pathways to becoming highly cited.

    Endovascular interventions for intracranial aneurysms have evolved substantially over the past several decades. A citation rank list is used to measure the scientific and/or clinical impact of an article. Our objective was to identify and analyze the characteristics of the 100 most cited articles in the field of endovascular therapy for intracranial aneurysms. We performed a retrospective bibliometric analysis between July and August 2017. Articles were searched on the Science Citation Index Expanded database using Web of Science in order to identify the most cited articles in the endovascular therapy of intracranial aneurysms since 1945. Using selected key terms ('intracranial aneurysm', 'aneurysm', 'aneurysmal subarachnoid', 'endovascular', 'coiling', 'stent-assisted', 'balloon-assisted', 'flow-diversion') yielded a total of 16 314 articles. The top 100 articles were identified and analyzed to extract relevant information, including citation count, authorship, article type, subject matter, institution, country of origin, and year of publication. Citations for the top 100 articles ranged from 133 to 1832. All articles were cited an average of 27 times per year. There were 45 prospective studies, including 7 level-II randomized controlled trials. Most articles were published in the 2000s (n=53), and the majority constituted level III or level IV evidence. Half of the top 100 articles arose from the USA. This study provides a comprehensive overview of the most cited articles in the endovascular management of intracranial aneurysms. It recognizes the contributions made by key authors and institutions, providing an important framework to an enhanced understanding of the evidence behind the endovascular treatment of aneurysms. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

  17. Comparing the characteristics of highly cited titles and highly alted titles

    Energy Technology Data Exchange (ETDEWEB)

    Didegah, F.; Bowman, T.D.; Bowman, S.; Hartley, J.

    2016-07-01

    This study examines differences in the types of titles for articles that show high altmetric activity (highly alted articles) versus highly cited articles. This work expands on previous research on document titles in combination with a grounded theory approach to develop a codebook in which articles were manually coded based on 11 characteristics. The results show that there are differences and similarities in titles across many of the examined characteristics; highly cited titles and highly mentioned titles on Wikipedia have some similar characteristics such as they have the the highest percentage of substantive words; in addition, there are no or very few titles referencing outside or with humor/lightness on both platforms. Twitter and Facebook also showed some similarities having the highest percentage of humorous/light titles and lowest percentage of substantive words in their titles. (Author)

    The actual implementations in guaranteeing the reliability of NDE systems applied in service inspections in nuclear power plants will be presented. The difference between the American PDI (Performance Demonstration Initiative) which is based on blind trials and the European ENIQ (European Network for Inspection Qualification) approach which is based on a mixed procedure of physical modeling, experience data and test experiments will be discussed. The ROC (Receiver Operating Characteristic) has been adapted from the signal detection theory to NDE problems at BAM to be used for basic investigations and for the validation of new exceptional NDE systems where modeling and reference to standards is not yet possible. Examples of application will be shown and critical discussed especially concerning the influence of the grading unit raster

  19. Cited2 Regulates Neocortical Layer II/III Generation and Somatosensory Callosal Projection Neuron Development and Connectivity.

    The neocortex contains hundreds to thousands of distinct subtypes of precisely connected neurons, allowing it to perform remarkably complex tasks of high-level cognition. Callosal projection neurons (CPN) connect the cerebral hemispheres via the corpus callosum, integrating cortical information and playing key roles in associative cognition. CPN are a strikingly diverse set of neuronal subpopulations, and development of this diversity requires precise control by a complex, interactive set of molecular effectors. We have found that the transcriptional coregulator Cited2 regulates and refines two stages of CPN development. Cited2 is expressed broadly by progenitors in the embryonic day 15.5 subventricular zone, during the peak of superficial layer CPN birth, with a progressive postmitotic refinement in expression, becoming restricted to CPN of the somatosensory cortex postnatally. We generated progenitor-stage and postmitotic forebrain-specific Cited2 conditional knock-out mice, using the Emx1-Cre and NEX-Cre mouse lines, respectively. We demonstrate that Cited2 functions in progenitors, but is not necessary postmitotically, to regulate both (1) broad generation of layer II/III CPN and (2) acquisition of precise area-specific molecular identity and axonal/dendritic connectivity of somatosensory CPN. This novel CPN subtype-specific and area-specific control from progenitor action of Cited2 adds yet another layer of complexity to the multistage developmental regulation of neocortical development. This study identifies Cited2 as a novel subtype-specific and area-specific control over development of distinct subpopulations within the broad population of callosal projection neurons (CPN), whose axons connect the two cerebral hemispheres via the corpus callosum (CC). Currently, how the remarkable diversity of CPN subtypes is specified, and how they differentiate to form highly precise and specific circuits, are largely unknown. We found that Cited2 functions within

    Background and purpose: Protein synthesis rates are greatly reduced under hypoxic conditions as a consequence of an overall inhibition of mRNA translation. Certain specific mRNA species have the ability to escape this general translational repression. At the cellular level this results in differential protein expression during hypoxic conditions. The objective of this study was to characterize the translational regulation of the postulated HIF-1α antagonist Cited2. Materials and methods: DU145 prostate carcinoma cells and mouse embryonic fibroblasts with a homozygous knock-in mutation for eIF2α (S51A) or wild-type eIF2α were exposed to severe hypoxia after which both total mRNA and efficiently translated mRNA were isolated. Quantitative RT-PCR was used to measure and compare changes in transcription (total mRNA) with changes in translation (efficiently translated mRNA fraction). Results: We show using HIF-1α null MEF cells that transcriptional induction of Cited2 during hypoxia is dependent on HIF-1α. Although global mRNA translation is inhibited during hypoxia Cited2 mRNA remains efficiently translated. An evolutionary conserved upstream open reading frame (uORF) in the 5'UTR of Cited2 did not stimulate translation in an eIF2α dependent manner during hypoxia. Conclusions: Selective translation Cited2 by an eIF2α independent mechanism establishes a link between translation and HIF-1 dependent transcription during hypoxia

    The advent of social networking sites has facilitated the dissemination of scientific research. This article aims to investigate the presence of Iranian highly cited clinicians in social networking sites. This is a scientometrics study. Essential Science Indicator (ESI) was searched for Iranian highly cited papers in clinical medicine during November-December 2015. Then, the authors of the papers were checked and a list of authors was obtained. In the second phase, the authors' names were searched in the selected social networking sites (ResearchGate [RG], Academia, Mendeley, LinkedIn). The total citations and h-index in Scopus were also gathered. Fifty-five highly cited papers were retrieved. A total of 107 authors participated in writing these papers. RG was the most popular (64.5%) and LinkedIn and Academia were in 2 nd and 3 rd places. None of the authors of highly cited papers were subscribed to Mendeley. A positive direct relationship was observed between visibility at social networking sites with citation and h-index rate. A significant relationship was observed between the RG score, citations, reads indicators in RG, and citation numbers and there was a significant relationship between the number of document indicator in Academia and the citation numbers. It seems putting the papers in social networking sites can influence the citation rate. We recommend all scientists to be present at social networking sites to have better chance of visibility and also citation.

  3. Citing a Data Repository: A Case Study of the Protein Data Bank.

    The Protein Data Bank (PDB) is the worldwide repository of 3D structures of proteins, nucleic acids and complex assemblies. The PDB's large corpus of data (> 100,000 structures) and related citations provide a well-organized and extensive test set for developing and understanding data citation and access metrics. In this paper, we present a systematic investigation of how authors cite PDB as a data repository. We describe a novel metric based on information cascade constructed by exploring the citation network to measure influence between competing works and apply that to analyze different data citation practices to PDB. Based on this new metric, we found that the original publication of RCSB PDB in the year 2000 continues to attract most citations though many follow-up updates were published. None of these follow-up publications by members of the wwPDB organization can compete with the original publication in terms of citations and influence. Meanwhile, authors increasingly choose to use URLs of PDB in the text instead of citing PDB papers, leading to disruption of the growth of the literature citations. A comparison of data usage statistics and paper citations shows that PDB Web access is highly correlated with URL mentions in the text. The results reveal the trend of how authors cite a biomedical data repository and may provide useful insight of how to measure the impact of a data repository.

    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

In this paper, we present a methodology that uses such reference models as a starting point for a top-down integration of enterprise applications. The re-engineered models of legacy systems are individually linked via cross-mapping specifications to the forward-engineered reference model's specification. The actual linking of reference and legacy models is done with a methodology for connecting (new business objects with (old legacy systems.

    Full Text Available Nowadays, three most popular citation databases are Web of Science (WoS, Scopus and Google Scholar (GS. In contrast to WoS and Scopus, GS is freely accessible. Comparing the three citation databases, WoS and Scopus have precisely defined and published criteria for selection of sources and papers from these sources. Google’s policy is quite non-transparent. In recent times, however, scientists have been increasingly citing data from GS in addition to data on presence and citations in databases WoS and Scopus. In the conclusion of a comparative analysis of number of citations of papers published in the Croatian Medical Journal in 2005 and 2006 according to the three citation databases, it is emphasized that GS may serve as an alternative bibliometric measure of citation frequency (Šember et al. 2010. An investigation of the number of citations for scientists from the fields of library and information sciences for the period 1996–2005, according to the three mentioned citation databases, has shown, among other things, that citations collected by GS are very useful. They are not of the same quality and significance as those from WoS and Scopus, but they point at a broader international echo of the cited papers than results obtained using WoS and Scopus (Meho, Yang 2007.

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

    2010-02-01

    The term "citation classic" has been used in reference to an article that has been cited more than 400 times. The purpose of this study is to identify such articles that pertain to clinical neurosurgery. A list of search phrases relating to neurosurgery was compiled. A topic search was performed using the Institute for Scientific Information Web of Science for phrases. Articles with more than 400 citations were identified, and nonclinical articles were omitted. The journals, year of publication, topics, and study types were analyzed. There were 106 articles with more than 400 citations relating to clinical neurosurgery. These articles appeared in 28 different journals, with more than half appearing in the Journal of Neurosurgery or the New England Journal of Medicine. Fifty-three articles were published since 1990. There were 38 articles on cerebrovascular disease, 21 on stereotactic and functional neurosurgery, 21 on neurooncology, 19 on trauma, 4 on nontraumatic spine, 2 on CSF pathologies, and 1 on infection. There were 29 randomized trials, of which 86% appeared in the New England Journal of Medicine, Lancet, or the Journal of the American Medical Association, and half concerned the prevention or treatment of stroke. In addition, there were 16 prospective studies, 15 classification or grading systems, and 7 reviews. The remaining 39 articles were case series, case reports, or technical notes. More than half of the citation classics identified in this study have been published in the past 20 years. Case series, classifications, and reviews appeared more frequently in neurosurgical journals, while randomized controlled trials tended to be published in general medical journals.

    1993-01-01

    In this paper the performance of Model Reference Adaptive Control (MRAC) is studied in numerical simulations and verified experimentally with the objective of understanding how differences between the plant and the reference model affect the control effort. MRAC is applied analytically and experimentally to a single degree of freedom system and analytically to a MIMO system with controlled differences between the model and the plant. It is shown that the control effort is sensitive to differences between the plant and the reference model. The effects of increased damping in the reference model are considered, and it is shown that requiring the controller to provide increased damping actually decreases the required control effort when differences between the plant and reference model exist. This result is useful because one of the first attempts to counteract the increased control effort due to differences between the plant and reference model might be to require less damping, however, this would actually increase the control effort. Optimization of weighting matrices is shown to help reduce the increase in required control effort. However, it was found that eventually the optimization resulted in a design that required an extremely high sampling rate for successful realization.

    We developed a standardized cost estimation method for occupational health (OH) services. The purpose of this study was to set reference OH services costs and to conduct OH services cost management assessments in two workplaces by comparing actual OH services costs with the reference costs. Data were obtained from retrospective analyses of OH services costs regarding 15 OH activities over a 1-year period in three manufacturing workplaces. We set the reference OH services costs in one of the three locations and compared OH services costs of each of the two other workplaces with the reference costs. The total reference OH services cost was 176,654 Japanese yen (JPY) per employee. The personnel cost for OH staff to conduct OH services was JPY 47,993, and the personnel cost for non-OH staff was JPY 38,699. The personnel cost for receipt of OH services-opportunity cost-was JPY 19,747, expense was JPY 25,512, depreciation expense was 34,849, and outsourcing cost was JPY 9,854. We compared actual OH services costs from two workplaces (the total OH services costs were JPY 182,151 and JPY 238,023) with the reference costs according to OH activity. The actual costs were different from the reference costs, especially in the case of personnel cost for non-OH staff, expense, and depreciation expense. Using our cost estimation tool, it is helpful to compare actual OH services cost data with reference cost data. The outcomes help employers make informed decisions regarding investment in OH services.

    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

    Full Text Available A review of the top-cited articles in a scientific discipline can identify areas of research that are well established and those in need of further development, and may, as a result, inform and direct future research efforts. Our objective was to identify and characterize the top-cited articles in traumatic brain injury (TBI. We used publically available software to identify the 50 TBI articles with the most lifetime citations, and the 50 TBI articles with the highest annual citation rates. A total of 73 articles were included in this review, with 27 of the 50 papers with the highest annual citation rates common to the cohort of 50 articles with the most lifetime citations. All papers were categorized by their primary topic or focus, namely: predictor of outcome, pathology/natural history, treatment, guidelines and consensus statements, epidemiology, assessment measures, or experimental model of TBI. The mean year of publication of the articles with the most lifetime citations and highest annual citation rates was, respectively, 1990 ± 14.9 years and 2003 ± 6.7 years. The 50 articles with the most lifetime citations typically studied predictors of outcome (34.0%, 17/50 and were specific to severe TBI (38.0%, 19/50. In contrast, the most common subject of papers with the highest annual citation rates was treatment of brain injury (22.0%, 11/50, and these papers most frequently investigated mild TBI (36.0%, 18/50. These findings suggest an intensified focus on mild TBI, which is perhaps a response to the dedicated attention these injuries are currently receiving in the context of sports and war, and because of their increasing incidence in developing nations. Our findings also indicate increased focus on treatment of TBI, possibly due to the limited efficacy of current interventions for TBI. This review provides a cross-sectional summary of some of the most influential articles in TBI, and a bibliometric examination of the current status of TBI

    Orthopedic sports medicine continues to evolve, owing much of its clinical management and practice to rigorous academic research. In this review, we identify and describe the top 100 cited articles in clinical sports medicine and recognize the authors and institutions driving the research. We collected articles (excluding basic science, animal, and cadaveric studies) from the 25 highest-impact sports medicine journals and analyzed them by number of citations, journal, publication date, institution, country, topic, and author. Mean number of citations was 408 (range, 229-1629). The articles were published in 7 journals, most in the 1980s to 2000s, and represented 15 countries. Thirty topics were addressed, with a heavy emphasis on anterior cruciate ligament injury and reconstruction, knee rating systems, rotator cuff reconstruction, and chondrocyte transplantation. The 3 most cited articles, by Insall and colleagues, Constant and Murley, and Tegner and Lysholm, addressed a knee, a shoulder, and another knee rating system, respectively. Several authors contributed multiple articles. The Hospital for Special Surgery and the University of Bern contributed the most articles (5 each). This study provides a comprehensive list of the past century's major academic contributions to sports medicine. Residents and fellows may use this list to guide their scholarly investigations.

    To assess whether there is a preference for international journal citation to the detriment of national ones in ten Brazilian medical journals, in two different periods. All references in the articles published in Arquivos Brasileiros de Oftalmologia, Revista Brasileira de Cirurgia Cardiovascular, Revista da Associação Médica Brasileira, São Paulo Medical Journal, Arquivos Brasileiros de Endocrinologia e Metabologia, Clinics, Jornal Brasileiro de Pneumologia, Revista da Sociedade Brasileira de Medicina Tropical, Revista Brasileira de Psiquiatria e Acta Ortopédica Brasileira in the years 2011 and 2007 were analyzed, assessing the number of articles published in national and international journals. A total of 36,125 references from 1,462 articles published in the 10 aforementioned journals were analyzed. Of the total number, 4.242 (11.74%) were from Brazilian journals. There was no significant difference between the two analyzed periods. A total of 453 (30,98%) of the articles studied non-cited brazilian papers,and 81 (5.54%) articles had more Brazilian than international references. Of total references analyzed, 11.74% were related to articles published in Brazilian journals. This number, when compared to the percentage of Brazilian articles published in the medical area, demonstrates a good number of citations of national articles. Copyright © 2012 Elsevier Editora Ltda.

    2016-12-01

    Full Text Available The main objective of this paper is to identify and define the core characteristics of the set of highly-cited documents in Google Scholar (document types, language, free availability, sources, and number of versions, on the hypothesis that the wide coverage of this search engine may provide a different portrait of these documents with respect to that offered by traditional bibliographic databases. To do this, a query per year was carried out from 1950 to 2013 identifying the top 1,000 documents retrieved from Google Scholar and obtaining a final sample of 64,000 documents, of which 40% provided a free link to full-text. The results obtained show that the average highly-cited document is a journal or book article (62% of the top 1% most cited documents of the sample, written in English (92.5% of all documents and available online in PDF format (86.0% of all documents. Yet, the existence of errors should be noted, especially when detecting duplicates and linking citations properly. Nonetheless, the fact that the study focused on highly cited papers minimizes the effects of these limitations. Given the high presence of books and, to a lesser extent, of other document types (such as proceedings or reports, the present research concludes that the Google Scholar data offer an original and different vision of the most influential academic documents (measured from the perspective of their citation count, a set composed not only of strictly scientific material (journal articles but also of academic material in its broadest sense.

    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.

    The citations received by a scientific publication have been used as a proxy measurement of scientific quality and in ranking researchers. Although these practices have been observed in several institutes, careful assessment of top-cited articles may provide more insight into exploring their characteristics. The aim of this study was to analyze the top-cited articles in medical education identified by Azer 2015 and explore the characteristics of these articles that can provide insight into their assessment. The most frequently cited articles identified by searching the Web of Science under the category "Education, Scientific Discipline" were included in the analysis. The following issues were further analyzed: 1) comparing the mean yearly citations received by articles published before the year 2000 and those published after, 2) assessing whether there was a correlation between the number of grants, number of authors, number of institutes, or number of countries involved and the number of citations received, 3) assessing the number of female representation in authorship, 4) assessing the representation of none-medical staff in the authorship, and 5) exploring any association between top authors identified and those who were awarded the Karolinska Institutet Prize for research in medical education. Although there was no correlation between the number of citations and the number of years since publications, the mean number of citations received by articles published before the year 2000 varied from zero to 18.2 ± 16.6, whereas for those published after the year 2000 the mean varied from 2.0 ± 2.1 to 35.3 ± 26.8. No correlation was found between the number of citations obtained and number of grants, number of authors, number of institutes, or number of countries involved. Females comprised 50% of the total number of authors. However, no correlation was found between the number of females in authorship and the number of citations obtained. Similarly, the number of

    The project on the Reference Korean was initiated in 1980. Physical data have been compiled for 21,406 Korean people, corresponding to 0.05% of total Korean population. All the data were divided into small groups according to the age and sex. Internal organ mass data are cited from a report previously prepared the Chungham National University. The mass of Korean organs is similar to that of Japanese, but the weights of liver and pancreas were different with those of Japanese. This might be caused by the difference of the criterion of weighing methods but not by the real difference. (author)

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

The MRCs have been maintained for three decades, largely as a volunteer effort by a global network of curators at more than a dozen institutions (Fig.1, Table 1. They were originallyintended to provide a permanent micropaleontological archive for the DSDP; however, as their geographic and stratigraphic coverage has increased they have become increasingly valuable for research and teaching. This article describes the MRCs and their current usage, identifi es the need to maintain and improve the accuracy of the microfossil taxonomy upon which most DSDP and ODP geochronologyis based, and cites the potential for the future use of the MRCs by the Integrated Ocean Drilling Program (IODP.

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

    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.

    Objective To identify the 50 top-cited spine articles from mainland China and to analyze their main characteristics. Methods Web of Science was used to identify the 50 top-cited spine articles from mainland China in 27 spine-related journals. The title, year of publication, number of citations, journal, anatomic focus, subspecialty, evidence level, city, institution and author were recorded. Results The top 50 articles had 29-122 citations and were published in 11 English-language journals; most (32) were published in the 2000s. The journal Spine had the largest number of articles and The Lancet had the highest impact factor. The lumber spine was the most discussed anatomic area (18). Degenerative spine disease was the most common subspecialty topic (22). Most articles were clinical studies (29); the others were basic research (21). Level IV was the most common evidence level (17). Conclusions This list indicates the most influential articles from mainland China in the global spine research community. Identification of these articles provides insights into the trends in spine care in mainland China and the historical contributions of researchers from mainland China to the international spine research field.

    Even though citation analysis has several limitations, it is a commonly used tool to determine the impact of scientific articles in different research fields. The study aims to identify and systematically review the 100 most cited articles in the field of visceral surgery focusing on papers that modified therapeutic concepts and influenced the surgeons' decision making. The 100 most cited clinical articles in visceral surgery were identified using Journal Citation Reports and Science Citation Index Expanded of the Web of Science (Thomson Reuters, Philadelphia, Pa., USA). Data for characterization of the articles were determined: Number of citations, research topic, journal, publication time, authorship, country of origin, type of article and level of evidence if reasonable. The 100 most cited articles were published in 17 journals; 72 articles were found in the 3 journals: New England Journal of Medicine (38), Annals of Surgery (21) and Lancet (13). The oldest article was published in 1908 in Annals of Surgery (ranked 76th) and the most recent in 2012 in Lancet (65th). Eighty articles were published between 1990 and 2010. The number of citations ranged from 667 to 4,666 (median 925). The leading country of origin was the United States with 39 articles, followed by articles originating from more than one country (30). There were 45 interventional studies (27 randomized controlled trials), 32 observational studies, 19 reviews and 4 guidelines, definitions or classifications. The level of evidence was low (IV) in 42 articles and high in 35 articles (Ia or Ib). A high number of citations did not reflect a high level of evidence. The topics and research questions of the identified articles covered a large area of visceral surgery. Some of the milestones in visceral surgery were identified. The high impact measured by citations did not reflect a high quality of research (level of evidence) in a considerable number of publications. © 2016 S. Karger AG, Basel.

  2. Actualism and Fictional Characters

    Full Text Available http://dx.doi.org/10.5007/1808-1711.2016v20n1p61 In what follows, I present only part of a program that consists in developing a version of actualism as an adequate framework for the metaphysics of intentionality. I will try to accommodate in that framework suggestions found in Kripke’s works and some positions developed by Amie Thomasson. What should we change if we accept “fictional entities” in the domain of the actual world? Actualism is the thesis that everything that exists belongs to the domain of the actual world and that there are no possibilia. I shall defend that there are abstract artefacts, like fictional characters, and institutions. My argument could be seen as a version of Moore’s paradox: it is paradoxical to say: “I made (created it, but I do not believe it exists”. Moreover, there are true sentences about them. I will examine what it means to include abstract artefacts in the domain of the actual world. I favour a use of “exist” that includes beings with no concrete occupation of tri-dimensional space; to exist, it is enough to have been introduced at some moment in history. Abstract artefacts, like fictional characters, exist in that sense. I argue that it is important to distinguish two perspectives (internal and external in order to clarify the kind of knowledge we have of fictional characters. However, their existence presupposes a relation of dependence to a material basis and the mental activities of many people.

We studied the most cited journals, the signatures index, the type of document referred, the publication language, the distribution of geographical origin, and obsolescence and readiness index. We took into account all types of documents with the exception of Communications to Congresses. 345 articles were published at Nutr Hosp, containing 8,113 bibliographic references, with a median of 18, a maximum of 136 and minimum of 0 BR per article. The mean (rate of publications per published article during the specified period) is 23.52 (95% IC 20.93-26.10) and the mean at 5% is 20.66 per article. The 25th and 75th percentiles are 6 and 32, respectively, the interquartile interval being 26 BR per document. The semi-period of Burton and Kebler is 7 years and the Price Index is 38.18%. The bibliographic references, the consumption of information, of the articles published at Nutrición Hospitalaria present parameters similar to other journals on health science. However, good data on obsolescence are observed, which reveal the good validity of most of the references studied.

    Communication of critical results from diagnostic procedures between caregivers is a Joint Commission national patient safety goal. Evaluating critical result communication often requires manual analysis of voluminous data, especially when reviewing unstructured textual results of radiologic findings. Information retrieval (IR) tools can facilitate this process by enabling automated retrieval of radiology reports that cite critical imaging findings. However, IR tools that have been developed for one disease or imaging modality often need substantial reconfiguration before they can be utilized for another disease entity. THIS PAPER: 1) describes the process of customizing two Natural Language Processing (NLP) and Information Retrieval/Extraction applications - an open-source toolkit, A Nearly New Information Extraction system (ANNIE); and an application developed in-house, Information for Searching Content with an Ontology-Utilizing Toolkit (iSCOUT) - to illustrate the varying levels of customization required for different disease entities and; 2) evaluates each application's performance in identifying and retrieving radiology reports citing critical imaging findings for three distinct diseases, pulmonary nodule, pneumothorax, and pulmonary embolus. Both applications can be utilized for retrieval. iSCOUT and ANNIE had precision values between 0.90-0.98 and recall values between 0.79 and 0.94. ANNIE had consistently higher precision but required more customization. Understanding the customizations involved in utilizing NLP applications for various diseases will enable users to select the most suitable tool for specific tasks.

  12. The top-cited articles in medical education: a bibliometric analysis.

    2015-08-01

    To identify and examine the characteristics of the 50 top-cited articles in medical education. Two searches were conducted in the Web of Knowledge database in March 2014: a search of medical education journals in the category "Education, Scientific Discipline" (List A) and a keyword search across all journals (List B). Articles identified were reviewed for citation count, country of origin, article type, journal, authors, and publication year. Both lists included 56 articles, not 50, because articles with the same absolute number of citations shared the same rank. The majority of List A articles were published in Academic Medicine (34; 60.7%) and Medical Education (16; 28.6%). In List B, 27 articles (48.2%) were published in medical education journals, 19 (33.9%) in general medicine and surgery journals, and 10 (17.9%) in higher education and educational psychology journals. Twenty-six articles were included in both lists, with different rankings. Reviews and articles constituted the majority of articles; there were only 8 research papers in List A and 13 in List B. Articles mainly originated from the United States, Canada, the Netherlands, and the United Kingdom. The majority were published from 1979 to 2007. There was no correlation between year and citation count. The finding that over half of List B articles were published in nonmedical education journals is consistent with medical education's integrated nature and subspecialty breadth. Twenty of these articles were among their respective non-medical-education journals' 50 top-cited papers, showing that medical education articles can compete with subject-based articles.

    Whenever gene expression is being examined, it is essential that a normalization process is carried out to eliminate non-biological variations. The use of reference genes, such as glyceraldehyde-3-phosphate dehydrogenase, actin, and ribosomal protein genes, is the usual method of choice for normalizing gene expression. Although reference genes are used to normalize target gene expression, a major problem is that the stability of these genes differs among tissues, developmental stages, species, and responses to abiotic factors. Therefore, the use and validation of multiple reference genes are required. This review discusses the reasons that why RT-qPCR has become the preferred method for validating results of gene expression profiles, the use of specific and non-specific dyes and the importance of use of primers and probes for qPCR as well as to discuss several statistical algorithms developed to help the validation of potential reference genes. The conflicts arising in the use of classical reference genes in gene normalization and their replacement with novel references are also discussed by citing the high stability and low stability of classical and novel reference genes under various biotic and abiotic experimental conditions by employing various methods applied for the reference genes amplification.

    Full Text Available Reproducibility and reusability of research results is an important concern in scientific communication and science policy. A foundational element of reproducibility and reusability is the open and persistently available presentation of research data. However, many common approaches for primary data publication in use today do not achieve sufficient long-term robustness, openness, accessibility or uniformity. Nor do they permit comprehensive exploitation by modern Web technologies. This has led to several authoritative studies recommending uniform direct citation of data archived in persistent repositories. Data are to be considered as first-class scholarly objects, and treated similarly in many ways to cited and archived scientific and scholarly literature. Here we briefly review the most current and widely agreed set of principle-based recommendations for scholarly data citation, the Joint Declaration of Data Citation Principles (JDDCP. We then present a framework for operationalizing the JDDCP; and a set of initial recommendations on identifier schemes, identifier resolution behavior, required metadata elements, and best practices for realizing programmatic machine actionability of cited data. The main target audience for the common implementation guidelines in this article consists of publishers, scholarly organizations, and persistent data repositories, including technical staff members in these organizations. But ordinary researchers can also benefit from these recommendations.

    2010-01-01

    The actual nuclear R and D issues require new technologies and continuous progress in order to find adequate and effective solutions in sustained and increasing energy demand. The current tendency in energy consumption and occurring of large consumers, especially from Asian countries, imposes finding new means for energy clean, large scale and sustained production. NPPs reliability and availability were permanently monitored and improved; in the mean time the safety of the nuclear energy production was under surveillance. Corresponding development of the new technologies and discovery of improved materials and adequate technological processes offers the possibilities for appropriate implementation and use of them in the NPPs systems configuration and functioning/operation. The modern technologies and scientific discoveries, also the international cooperation, offer the opportunities to brake the actual barriers in order to cumulate and use advanced energy production processes in finding new energy sources and to build improved, reliable and safety power plants. The monitoring systems, intelligent sensors and intelligent SSCs, nanotechnologies and and modern and intelligent materials constitute the main reasons in improvement of the NPPs systems configuration and processes. The paper presents: - The state of the art in the level of actual and useful technologies for nuclear power systems development; - The actual technological limits that need to be over passed for NPPs systems improvements; - The main systems that need improvement and reconfiguration for actual NPPs development and increase in efficient operation, appropriate availability and total safety; - The actual energy production issues; - The key arguments in sustaining the R and D new NPPs systems development; - Future trends in NPPs development; - The limitations in industrial processes knowledge and use.

    This review covers the available literature concerning ground-disposed wastes and effluents of a potential oil shale industry. Ground disposal has been proposed for essentially all of the solid and liquid wastes produced (Pfeffer, 1974). Since an oil shale industry is not actually in operation, the review is anticipatory in nature. The section, Oil Shale Technology, provides essential background for interpreting the literature on potential shale oil wastes and the topics are treated more completely in the section entitled Environmental Aspects of the Potential Disposal of Oil Shale Wastes to Ground. The first section of the annotated bibliography cites literature concerning potential oil shale wastes and the second section cites literature concerning oil shale technology. Each section contains references arranged historically by year. An index is provided.

    2014-05-01

    The most-cited papers (MCPs) are likely those that impressed researchers and had profound influence on clinical practice or future developments in the related scientific field. This study was conducted to explore a bibliometric approach to assess where the oncology-related MCPs have been published in. The source of the data presented in this study was provided by using the InCitesTM, Web of Science, Thomson Reuters Database (2013). It contained any journal indexed by ISI between 1979 and 2013. The term MCPs arbitrarily defined as equal or more than 100 citations. A total of 565 publications were cited equal or more than 100 times. They were published in 79 different journals (64 oncology, 12 medicine, and 3 science), led by the Journal of Clinical Oncology (n = 76; 13.5%) and Cancer Research (n = 66; 11.7%) followed by Oncogene (n = 46; 8.1%), Nature Reviews Cancer (n = 41; 7.3%), and Cancer (n = 37; 6.5%). Moreover, the journal categories with the MCPs were the Oncology with 495 articles (87.6%), followed by the Medicine with 60 (10.6%) articles. However, the numbers of journals related to Science (n = 10; 1.8%) were the least. The MCPs were cited a total of 118,531 times. The citations ranged from 100 to 1,790, and the median number was 149. The total numbers of MCPs were the most prominent for the journals, the New England Journal of Medicine (median 398), Lancet (median 213), and Nature Reviews Cancer (median 210). In other side, the counts of MCPs were the highest for the Science and Medicine-categorized journals (median 212.5 and 192.5 citations, respectively). The MCPs categorized as Oncology were the least cited (median 145). The median number of MCPs per year was 18.7 with range 4.1-858.5. The annual most valuable MCPs were also published in the journal Nature Reviews Cancer (median 42) and the New England Journal of Medicine (median 38.7). Likewise, the numbers of MCPs were the highest for the Science-categorized journals (median

    2003-01-01

    This report presents the work that followed the CSSX model development completed in FY2002. The developed cesium and potassium extraction model was based on extraction data obtained from simple aqueous media. It was tested to ensure the validity of the prediction for the cesium extraction from actual waste. Compositions of the actual tank waste were obtained from the Savannah River Site personnel and were used to prepare defined simulants and to predict cesium distribution ratios using the model. It was therefore possible to compare the cesium distribution ratios obtained from the actual waste, the simulant, and the predicted values. It was determined that the predicted values agree with the measured values for the simulants. Predicted values also agreed, with three exceptions, with measured values for the tank wastes. Discrepancies were attributed in part to the uncertainty in the cation/anion balance in the actual waste composition, but likely more so to the uncertainty in the potassium concentration in the waste, given the demonstrated large competing effect of this metal on cesium extraction. It was demonstrated that the upper limit for the potassium concentration in the feed ought to not exceed 0.05 M in order to maintain suitable cesium distribution ratios

    A bibliometric analysis was completed of peer-reviewed literature from 1991-2015, written by American occupational therapists, to examine US high impact scholarship with "occupational therapy" and "occupational therapist(s)" used as keywords to search journal articles' publication title, abstract, author details, and keywords. Results included 1,889 journal articles from 1991-2015 published by American occupational therapists as first or corresponding author. Sixty-nine articles attained a TotalCitation 2015 ≥ 50 and 151 attained a Citation 2015 ≥ 5 indicating that they were the most highly cited literature produced in this period. Although the majority (58%) of this literature was published in occupational therapy-specific journals, 41% was published in interdisciplinary journals. Results illustrate that the volume of highly cited American occupational therapy peer-reviewed literature has grown over the last two decades. There is need for the profession to strategize methods to enhance the publication metrics of occupational therapy-specific journals to reduce the loss of high quality publications to external periodicals.

  12. Should we build more large dams? The actual costs of hydropower megaproject development

    International Nuclear Information System (INIS)

    Ansar, Atif; Flyvbjerg, Bent; Budzier, Alexander; Lunn, Daniel

    2014-01-01

    A brisk building boom of hydropower mega-dams is underway from China to Brazil. Whether benefits of new dams will outweigh costs remains unresolved despite contentious debates. We investigate this question with the “outside view” or “reference class forecasting” based on literature on decision-making under uncertainty in psychology. We find overwhelming evidence that budgets are systematically biased below actual costs of large hydropower dams—excluding inflation, substantial debt servicing, environmental, and social costs. Using the largest and most reliable reference data of its kind and multilevel statistical techniques applied to large dams for the first time, we were successful in fitting parsimonious models to predict cost and schedule overruns. The outside view suggests that in most countries large hydropower dams will be too costly in absolute terms and take too long to build to deliver a positive risk-adjusted return unless suitable risk management measures outlined in this paper can be affordably provided. Policymakers, particularly in developing countries, are advised to prefer agile energy alternatives that can be built over shorter time horizons to energy megaprojects. - Highlights: • We investigate ex post outcomes of schedule and cost estimates of hydropower dams. • We use the “outside view” based on Kahneman and Tversky's research in psychology. • Estimates are systematically and severely biased below actual values. • Projects that take longer have greater cost overruns; bigger projects take longer. • Uplift required to de-bias systematic cost underestimation for large dams is +99%

    2015-05-15

    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.

    To identify and analyse the 100 most cited papers on stress in nurses published in nursing journals. The number of citations an article receives is an index of its impact on the scientific community. An analysis of the most cited articles on stress in nursing would allow us to identify the most important articles and to obtain information about this area of knowledge. A retrospective bibliometric analysis. In 2016, 111 journals belonging to the "nursing" category were identified in the Science and Social Science Citation Index. A search was performed of the Science Core Collection Website for articles on stress published in these journals. The topic, type of article, publishing journal, countries and institutions of origin and year of publication were extracted from the articles. The impact factor, immediacy index, journal country and publisher and h index were collected from the Institute for Scientific Information. The citation density, citation tendency and Bradford's law were calculated. They identified articles were mostly empirical quantitative studies with a transversal design, published from 1975 - 2011 in 23 journals. They were signed by 233 authors, most of whom are English-speaking from the USA and UK. The core distribution of the publications comprises a single journal, the Journal of Advanced Nursing. The study of stress in nursing has shown increased visibility and recognition each decade. The most recent articles have the highest number of citations, are the highest in rank and have the higher citation densities. © 2018 John Wiley & Sons Ltd.

  16. Hypochondria as an actual neurosis.

    Science.gov (United States)

    Nissen, Bernd

    2017-09-27

    Freud defined hypochondria as an actual neurosis. In this paper the actual neurosis will be interpreted as unbound traumatic elements which threaten the self. In severe hypochondria, breakdowns have occurred, as outlined by Winnicott. The nameless traumatic elements of the breakdown have been encapsulated. The moment these encapsulated elements are liberated, an actual dynamic takes place which threatens the self with annihilation. Projective identification is not possible because no idea of containment exists. The self tries to evacuate these elements projectively, thus triggering a disintegrative regression. However, the object of this projection, which becomes a malign introject, is felt to remove the remaining psychical elements, forcing the worthless residue back into the self. In a final re-introjection, the self is threatened by unintegration. To save the self, these elements are displaced into an organ which becomes hypochondriacal, an autistoid object, protecting itself against unintegration and decomposition. An autistoid dynamic develops between the hypochondriac organ, the ego and the introject. Two short clinical vignettes illustrate the regressive dynamical and metapsychological considerations.

    2012-01-01

    Objective: Safety issues in magnetic resonance imaging (MRI) are important, especially in fetal MRI. However, since basic data with respect of the effective exposure time in fetal MRI are not available, this study aimed to determine the actual imaging time during a fetal MRI study. Methods: 100 fetal MRI studies of singleton pregnancies performed on a 1.5 T system were analysed with respect to study duration (from starting the survey scan until the end of study), the number of sequences acquired, and the actual imaging time, which was calculated by adding up scan time of each sequence. Furthermore, each sequence type was analysed regarding the number of acquisitions, specific absorption rates (SAR), and duration. Results: Mean study duration was 34.6 min (range: 14–58 min; standard deviation (SD): 9.7 min), the average number of sequences acquired was 26.6 (range: 11–44, SD: 6.6). Actual scan time averaged 11.4 min (range: 4–19 min, SD: 4.0 min). Ultrafast T2-weighted and steady-state free-precession sequences accounted for 62.3% of actual scan time, and were distributed over the whole duration of the study. Conclusion: Actual imaging time only accounts for 33% of total study time and is not continuous. The remaining time is consumed by the preparation phases of the scanner, and is spent with planning sequences and the eventual repositioning of the coil and/or pregnant woman. These data may help to more accurately estimate the exposure to radiofrequency deposition and noise during fetal MRI studies.

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

    The Hirsch index or h-index is widely used to quantify the impact of an individual's scientific research output, determining the highest number h of a scientist's papers that received at least h citations. Several variants of the index have been proposed in order to give more or less preference to highly cited papers. I analyse the citation records of 26 physicists discussing various suggestions, in particular A, e, f, g, h(2), h_w, h_T, \\hbar, m, {\\pi}, R, s, t, w, and maxprod. The total number of all and of all cited publications as well as the highest and the average number of citations are also compared. Advantages and disadvantages of these indices and indicators are discussed. Correlation coefficients are determined quantifying which indices and indicators yield similar and which yield more deviating rankings of the 26 datasets. For 6 datasets the determination of the indices and indicators is visualized.

  1. Counting Highly Cited Papers for University Research Assessment: Conceptual and Technical Issues

    Science.gov (United States)

    Rodríguez-Navarro, Alonso

    2012-01-01

    A Kuhnian approach to research assessment requires us to consider that the important scientific breakthroughs that drive scientific progress are infrequent and that the progress of science does not depend on normal research. Consequently, indicators of research performance based on the total number of papers do not accurately measure scientific progress. Similarly, those universities with the best reputations in terms of scientific progress differ widely from other universities in terms of the scale of investments made in research and in the higher concentrations of outstanding scientists present, but less so in terms of the total number of papers or citations. This study argues that indicators for the 1% high-citation tail of the citation distribution reveal the contribution of universities to the progress of science and provide quantifiable justification for the large investments in research made by elite research universities. In this tail, which follows a power low, the number of the less frequent and highly cited important breakthroughs can be predicted from the frequencies of papers in the upper part of the tail. This study quantifies the false impression of excellence produced by multinational papers, and by other types of papers that do not contribute to the progress of science. Many of these papers are concentrated in and dominate lists of highly cited papers, especially in lower-ranked universities. The h-index obscures the differences between higher- and lower-ranked universities because the proportion of h-core papers in the 1% high-citation tail is not proportional to the value of the h-index.

  2. Establishing Local Reference Dose Values and Optimisation Strategies

    2000-01-01

    The revised EC Patient Directive 97/43 EURATOM introduces the concepts of clinical audit, diagnostic reference levels and optimisation of radiation protection in diagnostic radiology. The application of reference dose levels in practice involves the establishment of reference dose values as actual measurable operational quantities. These values should then form part of an ongoing optimisation and audit programme against which routine performance can be compared. The CEC Quality Criteria for Radiographic Images provides guidance reference dose values against which local performance can be compared. In many cases these values can be improved upon quite considerably. This paper presents the results of a local initiative in the North West of the UK aimed at establishing local reference dose values for a number of major hospital sites. The purpose of this initiative is to establish a foundation for both optimisation strategies and clinical audit as an ongoing and routine practice. The paper presents results from an ongoing trial involving patient dose measurements for several radiological examinations upon the sites. The results of an attempt to establish local reference dose values from measured dose values and to employ them in optimisation strategies are presented. In particular emphasis is placed on the routine quality control programmes necessary to underpin this strategy including the effective data management of results from such programmes and how they can be employed to optimisation practices.

    The paper describes a regular events CITES consisting of young scientists school and international conference as a tool for training and professional growth. The events address the most pressing issues of application of information-computational technologies in environmental sciences and young scientists’ training, diminishing a gap between university graduates’ skill and concurrent challenges. The viability of the approach to the CITES organization is proved by the fact that single event organized in 2001 turned into a series, quite a few young participants successfully defended their PhD thesis and a number of researchers became Doctors of Science during these years. Young researchers from Russia and foreign countries show undiminishing interest to these events.

  4. Increasing the Reliability of Circulation Model Validation: Quantifying Drifter Slip to See how Currents are Actually Moving

    2016-02-01

    Ocean circulation forecasts can help answer questions regarding larval dispersal, passive movement of injured sea animals, oil spill mitigation, and search and rescue efforts. Circulation forecasts are often validated with GPS-tracked drifter paths, but how accurately do these drifters actually move with ocean currents? Drifters are not only moved by water, but are also forced by wind and waves acting on the exposed buoy and transmitter; this imperfect movement is referred to as drifter slip. The quantification and further understanding of drifter slip will allow scientists to differentiate between drifter imperfections and actual computer model error when comparing trajectory forecasts with actual drifter tracks. This will avoid falsely accrediting all discrepancies between a trajectory forecast and an actual drifter track to computer model error. During multiple deployments of drifters in Nantucket Sound and using observed wind and wave data, we attempt to quantify the slip of drifters developed by the Northeast Fisheries Science Center's (NEFSC) Student Drifters Program. While similar studies have been conducted previously, very few have directly attached current meters to drifters to quantify drifter slip. Furthermore, none have quantified slip of NEFSC drifters relative to the oceanographic-standard "CODE" drifter. The NEFSC drifter archive has over 1000 drifter tracks primarily off the New England coast. With a better understanding of NEFSC drifter slip, modelers can reliably use these tracks for model validation.

    Lafferty, Kevin D.; Suchanek, Tom

    2016-01-01

    “Food Web Complexity and Species Diversity” (Paine 1966) is the most-cited empirical article published in the American Naturalist. In short, Paine removed predatory sea stars (Pisaster ochraceus) from the rocky intertidal and watched the key prey species, mussels (Mytilus californianus), crowd out seven subordinate primary space-holding species. However, because these mussels are a foundational species, they provide three-dimensional habitat for over 300 associated species inhabiting the mussel beds; thus, removing sea stars significantly increases community-wide diversity. In any case, most ecologists cite Paine (1966) to support a statement that predators increase diversity by interfering with competition. Although detractors remained skeptical of top-down effects and keystone concepts, the paradigm that predation increases diversity spread. By 1991, “Food Web Complexity and Species Diversity” was considered a classic ecological paper, and after 50 years it continues to influence ecological theory and conservation biology.

    The status of citations can reflect the impact of a paper and its contribution to surgical practice. The aim of our study was to identify and review the 100 most-cited papers in general thoracic surgery. Relevant papers on general thoracic surgery were searched through Thomson Reuters Web of Science in the last week of November 2017. Results were returned in descending order of total citations. Their titles and abstracts were reviewed to identify whether they met our inclusion criteria by two thoracic surgeons independently. Characteristics of the first 100 papers, including title, journal name, country, first author, year of publication, total citations, citations in latest 5 years and average citation per year (ACY) were extracted and analyzed. Of the 100 papers, the mean number of citations was 322 with a range from 184 to 921. 19 journals published the papers from 1956 to 2012. Annals of Surgery had the largest number (29), followed by Journal of Thoracic and Cardiovascular Surgery (22) and Annals of Thoracic Surgery (21). The majority of the papers were published in 2000s (48) and originated from United States of America (62). There were 65 retrospective studies, 13 RCTs and 11 prospective studies. Orringer MB and Grillo HC contributed 4 first-author articles respectively. There were 53 papers on esophagus, 36 on lung, 6 on pleura and 5 on trachea. Our study identified the most-cited papers in the past several decades and offered insights into the development and advances of general thoracic surgery. It can help us understand the evidential basis of clinical decision-making today in the area. Copyright © 2018. Published by Elsevier Ltd.

  10. Prospect theory, reference points, and health decisions

    Directory of Open Access Journals (Sweden)

    2008-02-01

    Full Text Available In preventative health decisions, such as the decision to undergo an invasive screening test or treatment, people may be deterred from selecting the test because its perceived disutility relative to not testing is greater than the utility associated with prevention of possible disease. The prospect theory editing operation, by which a decision maker's reference point is determined, can have important effects on the disutility of the test. On the basis of the prospect theory value function, this paper develops two approaches to reducing disutility by directing the decision maker's attention to either (actual past or (expected future losses that result in shifted reference points. After providing a graphical description of the approaches and a mathematical proof of the direction of their effect on judgment, we briefly illustrate the potential value of these approaches with examples from qualitative research on prostate cancer treatment decisions.

  11. Association between imagined and actual functional reach (FR): a comparison of young and older adults.

    Recent studies indicate that the ability to mentally represent action using motor imagery declines with advanced age (>64 years). As the ability to represent action declines, the elderly may experience increasing difficulty with movement planning and execution. Here, we determined the association between estimation of reach via use of motor imagery and actual FR. Young adults (M=22 years) and older adults (M=66 years) estimated reach while standing with targets randomly presented in peripersonal (within actual reach) and extrapersonal (beyond reach) space. Imagined responses were compared to the individual's scaled maximum reach. FR, also while standing, was assessed using the standardized Functional Reach Test (FRT). Results for total score estimation accuracy showed that there was no difference for age; however, results for mean bias and distribution of error revealed that the older group underestimated while the younger group overestimated. In reference to FR, younger adults outperformed older adults (30 versus 14in.) and most prominent, only the younger group showed a significant relationship between estimation and FR. In addition to gaining insight to the effects of advanced age on the ability to mentally represent action and its association with movement execution, these results although preliminary, may have clinical implications based on the question of whether motor imagery training could improve movement estimations and how that might affect actual reach.

    Mrs. Wilson has made a genuine effort to include in this bibliography every significant reference to avian cholera since Louis Pasteur's articles appeared in 1880, although she recognizes the likelihood that a few have been overlooked. New listings have been added throughout 1978, but comprehensive coverage of the literature cannot be claimed beyond June of that year.Textbook accounts, because they are generally summaries of work published elsewhere, are excluded. Papers dealing primarily with the biology of Pasteurella multocida, as opposed to the disease it induces in birds, are also excluded, unless they report information of diagnostic usefulness. Short abstracts are not included unless the journals in which they are published are more widely available than those in which the complete articles appear or they are English summaries of foreign language articles.In compiling this bibliography, Mrs. Wilson has made extensive use of Biological Abstracts, the Pesticide Documentation Bulletin, and printouts generated by Bibliographic Retrieval Services, Inc. The "Literature Cited" sections of textbooks and journal articles pertinent to the subject were sources of many additional references. Regardless of the origin of the citation, its accuracy was confirmed by comparison with the original publication, except in those few instances (marked with an asterisk) when the journal was not on the shelves of the libraries accessible to us.The author will be grateful to users of the bibliography who point out errors or omissions.Wayne I.

    Full Text Available In the current age, the increased need for the restoration of forest ecosystems necessitates a better understanding of natural processes. Forest stands that are affected only by natural processes and disturbances can serve as references and controls for comparison with cut or otherwise managed forests. Such a comparison may help us determine, whether our sylvicultural practices actually pursue the goal of sustainable development. It is also important to use uniform terminology across the world to facilitate sharing of experiences and results. Creating reference and control stands in every ecoregion will provide a rich scientific basis for comparison with managed forests and allow us to design and apply restoration methods more effectively.

    Early pain and persistent parietal disorders remains a major unresolved problem in thoracic surgery. Thoracotomy and the use of multiple ports in most Video Assisted Thoracic Surgery (VATS) procedures are the major cause of this persistent pain. For the last decade, a few publications describing the use of either single incision VATS and cervical thoracic approaches have been reported without significant results in comparison with current used techniques. Intercostals compression during surgery and early after by intercostals chest tube placement, are probably the major cause of postoperative pain. Flexible endoscope is currently used in several surgeries and will take more and more importance in our daily use in thoracic surgery. Instrument flexibility allows its use through minimally invasive approaches and offers a very interesting intra-thoracic navigation. We describe here the first use in France of a flexible endoscope in thoracic surgery through a single cervical incision to perform simultaneous exploration and biopsies of the mediastinum and right pleura using the original approach of Cervical Incision Thoracic Endoscopic Surgery (CITES).

    To describe patterns of prosthesis wear and perceived prosthetic usefulness in adult acquired upper-limb amputees (ULAs). To describe prosthetic skills in activities of daily life (ADL) and the actual use of prostheses in the performance of ADL tasks. To estimate the influence of prosthetic skills on actual prosthesis use and the influence of background factors on prosthetic skills and actual prosthesis use. Cross-sectional study analysing population-based questionnaire data (n = 224) and data from interviews and clinical testing in a referred/convenience sample of prosthesis-wearing ULAs (n = 50). Effects were analysed using linear regression. 80.8% wore prostheses. 90.3% reported their most worn prosthesis as useful. Prosthetic usefulness profiles varied with prosthetic type. Despite demonstrating good prosthetic skills, the amputees reported actual prosthesis use in only about half of the ADL tasks performed in everyday life. In unilateral amputees, increased actual use was associated with sufficient prosthetic training and with the use of myoelectric vs cosmetic prostheses, regardless of amputation level. Prosthetic skills did not affect actual prosthesis use. No background factors showed significant effect on prosthetic skills. Most major ULAs wear prostheses. Individualised prosthetic training and fitting of myoelectric rather than passive prostheses may increase actual prosthesis use in ADL.

    2015-09-04

    To determine whether pharmaceutical advertisement claims targeting health professionals were supported by the randomised controlled trials (RCTs) cited in the advertisements, and to assess the risk of bias in those trials. Pharmaceutical advertisements were obtained from New Zealand Doctor and Pharmacy Today for the period July 2013 to June 2014. All claims made regarding efficacy, safety, and indications were identified and RCTs cited to substantiate these claims were examined. A claim was defined as supported by an RCT if the conclusions drawn in the paper were consistent with the claim. The quality of the RCT was assessed separately, using the Cochrane Risk of Bias Assessment Tool. In 25 (19%) of the 133 instances in which an RCT was cited, the published paper did not support the promotional claim. Moreover, there were only 10 (8%) instances in which the claim was supported by an RCT with a low risk of bias. Of the 78 cited RCTs, only 14% had a low risk of bias, while 49% had an unclear risk and 37% had a high risk. A high proportion of advertisements failed to meet New Zealand regulatory requirements that claims "are valid and have been substantiated".

    The degree to which consumers expect foods to satisfy hunger, referred to as expected satiation, has been reported to predict food intake. Yet this relationship has not been established precisely, at a quantitative level. We sought to explore this relationship in detail by determining whether expected satiation predicts the actual intake of semi-solid desserts. Two separate experiments were performed: the first used variations of a given food (eight apple purées), while the second involved a panel of different foods within a given category (eight desserts). Both experiments studied the consumption of two products assigned to volunteers based on their individual liking and expected satiation ratings, given ad libitum at the end of a standardised meal. A linear model was used to find predictors of food intake and included expected satiation scores, palatability scores, BMI, age, sex, TFEQ-R, TFEQ-D, water consumption during the meal, reported frequency of eating desserts, and reported frequency of consuming tested products as explanatory variables. Expected satiation was a significant predictor of actual food intake in both experiments (apple purée: F(1,97) = 18.60, P desserts: F(1,106) = 9.05, P desserts, on group and on individual level. Our results confirm the importance of expected satiation as a predictor of subsequent food intake, but highlight the need to study individual consumption behaviour and preferences in order to fully understand the role of expected satiation.

  1. In search of educational efficiency: 30 years of Medical Education's top-cited articles.

    Academic journals represent shared spaces wherein the significance of thematic areas, methodologies and paradigms are debated and shaped through collective engagement. By studying journals in their historical and cultural contexts, the academic community can gain insight into the ways in which authors and audiences propose, develop, harness, revise and discard research subjects, methodologies and practices. Thirty top-cited articles published in Medical Education between 1986 and 2014 were analysed in a two-step process. First, a descriptive classification of articles allowed us to quantify the frequency of content areas over the time span studied. Secondly, a discourse analysis was conducted to identify the continuities, disruptions and tensions within the three most prominent content areas. The top-cited articles in Medical Education focused on three major areas of interest: problem-based learning, simulation and assessment. In each of these areas of interest, we noted a tension between the desire to produce and apply standardised tools, and the recognition that the contexts of medical education are highly variable and influenced by political and financial considerations. The general preoccupation with achieving efficiency may paradoxically jeopardise the ability of medical schools to address the contextual needs of students, teachers and patients. Understanding the topics of interest for a journal's scholarly audience and how these topics are discursively positioned, provides important information for researchers in deciding how they wish to engage with the field, as well as for educators as they assess the relevance of educational products for their local contexts. © 2017 John Wiley & Sons Ltd and The Association for the Study of Medical Education.

    To evaluate the methodologic quality and relevance of references in pharmaceutical advertisements in the Canadian Medical Association Journal (CMAJ). Analytic study. All 114 references cited in the first 22 distinct pharmaceutical advertisements in volume 146 of CMAJ. Mean methodologic quality score (modified from the 6-point scale used to assess articles in the American College of Physicians' Journal Club) and mean relevance score (based on a new 5-point scale) for all references in each advertisement. Twenty of the 22 companies responded, sending 78 (90%) of the 87 references requested. The mean methodologic quality score was 58% (95% confidence limits [CL] 51% and 65%) and the mean relevance score 76% (95% CL 72% and 80%). The two mean scores were statistically lower than the acceptable score of 80% (p e., other than reports of clinical trials). Half of the advertisements had a methodologic quality score of less than 65%, but only five had a relevance score of less than 65%. Although the relevance of most of the references was within minimal acceptable limits, the methodologic quality was often unacceptable. Because advertisements are an important part of pharmaceutical marketing and education, we suggest that companies develop written standards for their advertisements and monitor their advertisements for adherence to these standards. We also suggest that the Pharmaceutical Advertising Advisory Board develop more stringent guidelines for advertising and that it enforce these guidelines in a consistent, rigorous fashion.

  3. Are the Most Highly Cited Articles the Ones that are the Most Downloaded? A Bibliometric Study of IRRODL

    Full Text Available Publication of research, innovation, challenges and successes is of critical importance to the evolution of more effective distance education programming. Publication in peer reviewed journal format is the most prestigious and the most widespread form of dissemination in education and most other disciplines, thus the importance of understanding what is published and its impact on both researchers and practitioners. In this article we identify and classify the leading articles in arguably the leading peer reviewed journals in this discipline. The journal The International Review of Research in Open and Distance Learning (IRRODL is a peer reviewed academic journal that has been published since 2000. The journal has published between 3 and 6 issues annually with between 50 and 111 research articles per volume. In order to assess the general and the particular impact of highly cited articles this work describes the main bibliometric indicators of the IRRODL journal and these are compared with the total galley views in all formats, PDF, HTML, EPUB and MP3, that IRRODL publishes. In addition to identifying characteristics of the most widely cited articles this research determines if there is a correlation between the articles most highly cited by other publishing researchers and the number of views, indicating interest from both practitioners and research communities. The results show a significant and positive relationship between the total number of citations and the number of views received by articles published in the journal, indicating the impact of the journal extends beyond active publishers to practitioner consumers.

    El trabajo tiene por finalidad poner en tensión las categorías de psicosis ordinaria y neurosis actuales. En primer lugar, se procede a examinar ambas categorías para luego establecer sus puntos de coincidencia y disidencia. Se concluye que la categoría de neurosis actual propuesta por Freud, es una posible expresión de lo que en la actualidad se llama psicosis ordinaria.

  6. Plant's sterilization rule for fertile women cited.

    Science.gov (United States)

    1979-01-01

    The American Cyanamid Corporation has been cited by the Occupational Safety and Health Administration (OSHA) for violating federal law by requiring female employees of childbearing age to be sterilized in order to continue working in areas of the plant where they would be exposed to high levels of airborne lead. High levels of airborne lead can cause damage to workers' reproductive systems and be responsible for birth defects in fetuses. The OSHA charged that American Cyanamid's policy constituted a "willful violation" of the 1970 Occupational Safety and Health Act. The Act requires employers to provide employment that is free from recognized hazards likely to cause death or physical harm. According to OSHA, the Act does not allow an employer to eliminate the hazard by compelling employees to choose between losing their jobs and undergoing sterilization. The reproductive health of workers is considered a valid part of OSHA's regulatory concern. The citation, which carries a $10,000 fine, grew out of a complaint that was filed by the Oil, Chemical and Atomic Workers Union on behalf of 5 female workers working in the lead pigment division of the company's Willow Island, West Virginia plant. The 5 employees alleged that they had themselves sterilized to avoid being transferred to other and possibly lower paying janitorial jobs or losing thier jobs completely. The company is appealing the citation. The union has also filed a complaint with the Equal Employment Opportunity Commission charging American Cyanamid with sex discrimination, since only the women workers are at risk of being transferred to lower paying jobs.

    An examination of actual HIV vaccine trials can contribute to an understanding of motivators for participation in these studies. Analysis of these motivators reveals that they can be categorized as social and personal benefits. Social benefits are generally altruistic, whereas personal benefits are psychological, physical, and financial. In this systematic review, the authors performed a literature search for actual preventive HIV vaccine trials reporting motivators to participation. Of studies conducted in the Organization for Economic Co-operation and Development (OECD) countries, the authors retrieved 12 studies reporting on social benefits and seven reporting on personal benefits. From the non-OECD countries, nine studies reported on social benefits and eight studies on personal benefits. Social benefits were most frequently described on macroscopic, altruistic levels. Personal benefits were most frequently psychological in nature. Rates of participation were compared between the OECD and the non-OECD countries. Knowledge of actual motivators in specific countries and regions can help target recruitment in various types of actual HIV vaccine trials.

  8. From Excessive Journal Self-Cites to Citation Stacking: Analysis of Journal Self-Citation Kinetics in Search for Journals, Which Boost Their Scientometric Indicators.

    Bibliometric indicators increasingly affect careers, funding, and reputation of individuals, their institutions and journals themselves. In contrast to author self-citations, little is known about kinetics of journal self-citations. Here we hypothesized that they may show a generalizable pattern within particular research fields or across multiple fields. We thus analyzed self-cites to 60 journals from three research fields (multidisciplinary sciences, parasitology, and information science). We also hypothesized that the kinetics of journal self-citations and citations received from other journals of the same publisher may differ from foreign citations. We analyzed the journals published the American Association for the Advancement of Science, Nature Publishing Group, and Editura Academiei Române. We found that although the kinetics of journal self-cites is generally faster compared to foreign cites, it shows some field-specific characteristics. Particularly in information science journals, the initial increase in a share of journal self-citations during post-publication year 0 was completely absent. Self-promoting journal self-citations of top-tier journals have rather indirect but negligible direct effects on bibliometric indicators, affecting just the immediacy index and marginally increasing the impact factor itself as long as the affected journals are well established in their fields. In contrast, other forms of journal self-citations and citation stacking may severely affect the impact factor, or other citation-based indices. We identified here a network consisting of three Romanian physics journals Proceedings of the Romanian Academy, Series A, Romanian Journal of Physics, and Romanian Reports in Physics, which displayed low to moderate ratio of journal self-citations, but which multiplied recently their impact factors, and were mutually responsible for 55.9%, 64.7% and 63.3% of citations within the impact factor calculation window to the three journals

    2007-11-01

    The objective with this report is to describe all the waste and the waste package that is expected to be deposited in SFR 1 at the time of closure. The report will form the basis for the release calculation in the safety analysis for SFR 1. Three different scenarios are explored in this report; the waste inventory is based on an estimated operational lifetime of the Swedish nuclear power plants of 50 and 60 years and that closure of the SFR 1 repository will take place in 2040 or 2050 respectively. The third scenario is where the repository is full (one part where the activity adds up to 1016 Bq and one part where the repository is considered full regarding volume). In the report, data about geometries, weights, materials, chemicals and radionuclide are given. No chemotoxic material has been identified in the waste. The inventory is estimated using the Prosit-interface which extracts information from the Triumf database. The inventory is based on so called 'waste types' and the waste types' 'reference waste package'. The reference waste package combined with a prognosis of the number of waste packages to be delivered to SFR 1 gives the final waste inventory for SFR 1. All reference waste packages are thoroughly described in the appendices of this report. The reference waste packages are as far as possible based on actual experiences and measurements. The radionuclide inventory is also based on actual measurements. The inventory is based on measurements of 60 Co and 137 Cs in waste packages and on measurements of 239 Pu and 240 Pu in reactor water. Other nuclides in the inventory are calculated with correlation factors

    2017-03-01

    In December 2016, Elsevier launched a new tool that helps measure the citation impact of academic journals, called the CiteScore index. The CiteScore index values for 2015 confirmed the status of Acta Dermatovenerologica Alpina, Pannonica et Adriatica (Acta Dermatovenerol APA) as the leading journal in dermatology and sexually transmitted infections in the region. Sixty-five articles published in Acta Dermatovenerol APA from 2012 to 2014 received a total of 77 citations in 2015, resulting in a CiteScore index value of 1.18 for the journal. More than half of the articles published from 2012 to 2014 received at least one citation in 2015. Acta Dermatovenerol APA performed well in all three categories listed because it is ranked 384th out of 1,549 journals in the category General Medicine (75th percentile), 53rd out of 122 journals in the category Dermatology (56th percentile), and 142nd out of 246 journals in the category Infectious Diseases (42nd percentile).

  11. How Serious of a Problem is Staff Turnover in Substance Abuse Treatment? A Longitudinal Study of Actual Turnover1

    Eby, Lillian T.; Burk, Hannah; Maher, Charleen P.

    2010-01-01

    In the substance abuse treatment field, the annual turnover rate is cited as being anywhere between 19 and 50 percent (Johnson & Roman, 2002; Gallon, Gabriel, & Knudsen, 2003; Knudsen et al., 2003; McLellan et al., 2003). However, no research to date has evaluated these claims by tracking turnover longitudinally using organizational turnover data from substance abuse treatment centers. This research presents the results of a longitudinal study designed to systematically examine actual turnover among counselors and clinical supervisors. Twenty-seven geographically dispersed treatment organizations, serving a wide range of clients in the public and private sector, provided data for the study over a two year time span (2008–2009). The annual turnover rate was 33.2% for counselors and 23.4% for clinical supervisors. For both groups the majority of turnover was voluntary (employee-initiated). Specific reasons for turnover were largely consistent across the two groups, with the most common reason being a new job or new opportunity. The findings are discussed in terms of the unique employment context of substance abuse treatment. Practical recommendations are also discussed to help stem the tide of turnover in the field of substance abuse treatment. PMID:20675097

    Full Text Available This study is meant to examine the relationships of several antecedents of actual purchase of herbal product in Malaysia. Actual purchase is considered to have a vital link to a business success. The study identified eight antecedents of consumer actual purchase such as intention, attitude, social influence, product safety and culture belief. A total of 473 respondents (about 82% completed and returned the questionnaire. A seven point Likert scale was used to measure responses. The data were analyzed using Partial Least Squares (PLS path modeling. The path coefficient results supported the direct influence of intention, attitude, social influence and product safety on actual buying. Moreover, the findings reveal that attitude, social influence, product safety, and culture belief also influenced buying intention.

    Dancers are highly susceptible to musculoskeletal injuries and frequently require interaction with medical professionals. While many dancers have a finely tuned awareness of their bodies, their knowledge of the fundamentals of human anatomy is not uniform. There is a paucity of literature on the benefits of human anatomy education in dancers, though it seems intuitive that there should be a relationship. The purpose of this study was to assess dancers' perceived and actual knowledge of basic musculoskeletal anatomy and its relationship to function. Adult dancers at the undergraduate, pre-professional, and professional levels were surveyed through an anonymous online questionnaire. Questions included demographic information, dance techniques studied, anatomy training, and injury history. Subjects rated their perceived knowledge of anatomy and were tested with 15 multiple-choice questions on basic musculoskeletal anatomy. Four hundred seventy-five surveys were completed. Ordinal regression showed a correlation of perceived to actual knowledge of anatomy (p < 0.001). Factors that correlated with increases in both perceived and actual knowledge of anatomy included having taken an anatomy course of any type (p < 0.001) and increased age (p ≤ 0.001). Years of dance training and professional dancer status both significantly correlated with increased knowledge of anatomy (p < 0.001) but not perceived knowledge. Chi-square analysis showed that dancers with training in either modern or jazz dance had a significantly higher perceived, but not actual, knowledge when compared to those without training in those styles of dance (p < 0.001 and p = 0.011, respectively). In conclusion, dancers generally scored well on questions pertaining to basic musculoskeletal anatomy, and their perception correlated with their actual knowledge of anatomy. Factors that contribute to dancers' knowledge of anatomy include age, years of experience, professional dancer status, and anatomy training.

  15. Criticality reference benchmark calculations for burnup credit using spent fuel isotopics

    Bowman, S.M.

    1991-04-01

    To date, criticality analyses performed in support of the certification of spent fuel casks in the United States do not take credit for the reactivity reduction that results from burnup. By taking credit for the fuel burnup, commonly referred to as ''burnup credit,'' the fuel loading capacity of these casks can be increased. One of the difficulties in implementing burnup credit in criticality analyses is that there have been no critical experiments performed with spent fuel which can be used for computer code validation. In lieu of that, a reference problem set of fresh fuel critical experiments which model various conditions typical of light water reactor (LWR) transportation and storage casks has been identified and used in the validation of SCALE-4. This report documents the use of this same problem set to perform spent fuel criticality benchmark calculations by replacing the actual fresh fuel isotopics from the experiments with six different sets of calculated spent fuel isotopics. The SCALE-4 modules SAS2H and CSAS4 were used to perform the analyses. These calculations do not model actual critical experiments. The calculated k-effectives are not supposed to equal unity and will vary depending on the initial enrichment and burnup of the calculated spent fuel isotopics. 12 refs., 11 tabs

    In scientific circles, the reference is the information that is necessary to the reader in identifying and finding used sources. The basic rule when listing the sources used is that references must be accurate, complete and should be consistently applied. On the other hand, quoting implies verbatim written or verbal repetition of parts of the text or words written by others that can be checked in original. Authors of every new scientific article need to explain how their study or research fits with previous one in the same or similar fields. A typical article in the health sciences refers to approximately 20-30 other articles published in peer reviewed journals, cite once or hundreds times. Citations typically appear in two formats: a) as in-text citations where the sources of information are briefly identified in the text; or b) in the reference list at the end of the publication (book chapter, manuscript, article, etc.) that provides full bibliographic information for each source. Group of publishers met in Vancouver in 1978 and decided to prescribe uniform technical propositions for publication. Adopted in the 1979 by the National Library of Medicine in Bethesda, then the International Committee of Medical Journals Editors (ICMJE), whose review in 1982 entered the official application by 300 international biomedical journals. Authors writing articles for publication in biomedical publications used predominantly citation styles: Vancouver style, Harward style, PubMed style, ICMJE, APA, etc. The paper gives examples of all of these styles of citation to the authors in order to facilitate their applications. Also in this paper is given the review about the problem of plagiarism which becomes more common in the writing of scientific and technical articles in biomedicine. PMID:24167381

    Brueckl, R.; Grunert, S.; Rosemeyer, B.

    1986-01-01

    The method developed by Rippstein and Mueller allows a mathematically exact determination of the femoral neck-shaft angle (CCD) and the angle of torsion (AT); already at a deviation of 5-10 0 from the prescribed position of the patient considerable errors (up to more than 15 0 ) may occur. For this reason two alternative methods are cited and described in detail: a) the cinematographic determination of the CCD- and AT-angle according to Schwetlick, and b) the combination of the determination of the AT-angle in exterior rotation according to Rogers and an anteroposterior roentgenogram of the pelvis and hips in interior rotation of the size of the AT-angle. Both methods are also mathematically exact, however, in addition almost independent from minor deviations in the position of the patient. It is advisable to apply one of the cited methods in cases of high AT-angle values (>>30 0 ), in cases where the placing of the patient is difficult and where the determination of the angles would require a major therapeutic measurement.

    Acute kidney injury (AKI) is a major global health issue, associated with poor short-term and long-term outcomes. Research on AKI is increasing with numerous articles published. However, the quantity and quality of research production in the field of AKI is unclear. To analyse the characteristics of the most cited articles on AKI and to provide information about achievements and developments in AKI, we searched the Science Citation Index Expanded for citations of AKI articles. For the top 100 most frequently cited articles (T100), we evaluated the number of citations, publication time, province of origin, journal, impact factor, topic or subspecialty of the research, and publication type. The T100 articles ranged from a maximum of 1971 citations to a minimum of 215 citations (median 302 citations). T100 articles were published from 1951 to 2011, with most articles published in the 2000s (n=77), especially the 5-year period from 2002 to 2006 (n=51). The publications appeared in 30 journals, predominantly in the general medical journals, led by New England Journal of Medicine (n=17), followed by expert medical journals, led by the Journal of the American Society of Nephrology (n=16) and Kidney International (n=16). The majority (83.7%) of T100 articles were published by teams involving ≥3 authors. T100 articles originated from 15 countries, led by the USA (n=81) followed by Italy (n=9). Among the T100 articles, 69 were clinical research, 25 were basic science, 21 were reviews, 5 were meta-analyses and 3 were clinical guidelines. Most clinical articles (55%) included patients with any cause of AKI, followed by the specific causes of contrast-induced AKI (25%) and cardiac surgery-induced AKI (15%). This study provides a historical perspective on the scientific progress on AKI, and highlights areas of research requiring further investigations and developments.

  2. Electrodermal responses to implied versus actual violence on television.

    1998-01-01

    The electrodermal response (EDR) of children watching a violent show was measured. Particular attention was paid to the type of violence (actual or implied) that prompted an EDR. In addition, the impact of the auditory component (sounds associated with violence) of the show was evaluated. Implied violent stimuli, such as the villain's face, elicited the strongest EDR. The elements that elicited the weakest responses were the actual violent stimuli, such as stabbing. The background noise and voices of the sound track enhanced the total number of EDRs. The results suggest that implied violence may elicit more fear (as measured by EDRs) than actual violence does and that sounds alone contribute significantly to the emotional response to television violence. One should not, therefore, categorically assume that a show with mostly actual violence evokes less fear than one with mostly implied violence.

    To assess whether a correlation exists between newsworthiness (Altmetric score) and scientific impact markers, such as citation analysis, impact factors, and levels of evidence. The top five most cited articles for the year 2014 and 2015 from the top 10 ranking urology journals (Scientific Impact Group) were identified. The top 50 articles each in 2014 and 2015 were identified from Altmetric support based on media activity (Media Impact Group). We determined the number of citations that these articles received in the scientific literature, and calculated correlations between citations with Altmetric scores. In the Scientific Impact Group, the mean number of citations per article was 37.6, and the most highly cited articles were oncology guidelines. The mean Altmetric score in these articles was 14.8. There was a weak positive correlation between citations and Altmetric score (r s = 0.35, 95% confidence interval 0.16-0.52, P scientifically rigorous, or that this audience places greater value on different subjects than the scientific community. © 2017 The Authors BJU International © 2017 BJU International Published by John Wiley & Sons Ltd.

  5. Analysis of the interacting partners eIF4F and 3'-CITE required for Melon necrotic spot virus cap-independent translation.

    2017-06-01

    We have shown previously that the translation of Melon necrotic spot virus (MNSV, family Tombusviridae, genus Carmovirus) RNAs is controlled by a 3'-cap-independent translation enhancer (CITE), which is genetically and functionally dependent on the eukaryotic translation initiation factor (eIF) 4E. Here, we describe structural and functional analyses of the MNSV-Mα5 3'-CITE and its translation initiation factor partner. We first mapped the minimal 3'-CITE (Ma5TE) to a 45-nucleotide sequence, which consists of a stem-loop structure with two internal loops, similar to other I-shaped 3'-CITEs. UV crosslinking, followed by gel retardation assays, indicated that Ma5TE interacts in vitro with the complex formed by eIF4E + eIF4G 980-1159 (eIF4F p20 ), but not with each subunit alone or with eIF4E + eIF4G 1003-1092 , suggesting binding either through interaction with eIF4E following a conformational change induced by its binding to eIF4G 980-1159 , or through a double interaction with eIF4E and eIF4G 980-1159 . Critical residues for this interaction reside in an internal bulge of Ma5TE, so that their mutation abolished binding to eIF4E + eIF4G 1003-1092 and cap-independent translation. We also developed an in vivo system to test the effect of mutations in eIF4E in Ma5TE-driven cap-independent translation, showing that conserved amino acids in a positively charged RNA-binding motif around amino acid position 228, implicated in eIF4E-eIF4G binding or belonging to the cap-recognition pocket, are essential for cap-independent translation controlled by Ma5TE, and thus for the multiplication of MNSV. © 2016 BSPP AND JOHN WILEY & SONS LTD.

  6. How to actualize potential: a bioecological approach to talent development.

    Ceci, Stephen J; Williams-Ceci, Sterling; Williams, Wendy M

    2016-08-01

    Bioecological theory posits three interacting principles to explain developmental outcomes such as fluctuating achievement levels and changing heritability coefficients. Here, we apply the theory to the domain of talent development, by reviewing short-term and long-term cognitive interventions. We argue that macro-level analyses of cultural practices (e.g., matrilineal inheritance and property ownership) and national systems of education are consistent with the bioecological theory; when the findings from these analyses are unpacked, the engines that drive them are so-called proximal processes. This finding has implications for the design and delivery of instruction and the development of talent. We argue that talent is fostered by the same three bioecological mechanisms that explain the actualization of genetic potential. We conclude by discussing several self-descriptions and personal narratives by gifted students in which they spontaneously refer to these bioecological mechanisms in their own talent-development processes. Similar testimonials have been documented by historic talent researchers such as Benjamin Bloom, noting the importance of continual adjustments in feedback. © 2016 New York Academy of Sciences.

    2016-06-01

    Full Text Available This study examined a collaborative inquiry process, facilitated by university faculty in an elementary school, intended to develop a research community, foster knowledge mobilization, and enhance student engagement. The Collaborative Inquiry Team in Education (CITE initiative consisted of five school-based sessions that included videos, discussions, and the completion of a research action plan. Data collection and analysis involved sessions’ transcripts, feedback from participants, documents such as brainstorming charts, and student artifacts. Findings indicate that the collaborative inquiry process with enablers of time, flexibility, and support from university faculty increased educators’ research acumen and student engagement in classrooms. The CITE initiative is an effective example of applied education research and knowledge mobilization with the inclusion of faculty and technological support, innovative resources, and the co-construction of new understandings.

    Full Text Available This paper presents the analysis of all references made by articles published at the four major Brazilian tourism journals. A total of 28,767 references in the 1,254 articles published since the first volume of each journal until the end of 2014. References were analyzed with respect to their type (journal, book, thesis, conference paper and others, place of publishing (Brazil or other countries and authorship. For the references of scientific articles, the names of these specific vehicles were identified. The results indicate the most cited authors, books, articles and journals. Impact factors of journals and the h-index of Hirsch (2005 of authors were also estimated. Moreover, techniques of social network analysis were applied to the representation of the relationships between authors and journals, besides estimating complex centrality indexes for these agents. The results also indicate some tendencies of change in the actual scenario arising from the strengthening of new authors and journals.

    Slimming cactus (Hoodia), found only in southwestern Africa, is a well-known herbal product for losing weight. Consequently, Hoodia extracts are sought-after worldwide despite a CITES Appendix II status. The failure to eradicate illegal trade is due to problems with detecting and identifying Hoodia using morphological and chemical characters. Our aim was to evaluate the potential of molecular identification of Hoodia based on DNA barcoding. Screening of nrITS1 and psbA-trnH DNA sequences from 26 accessions of Ceropegieae resulted in successful identification, while conventional chemical profiling using DLI-MS led to inaccurate detection and identification of Hoodia. The presence of Hoodia in herbal products was also successfully established using DNA sequences. A validation procedure of our DNA barcoding protocol demonstrated its robustness to changes in PCR conditions. We conclude that DNA barcoding is an effective tool for Hoodia detection and identification which can contribute to preventing illegal trade. © 2013 American Academy of Forensic Sciences.

    Citation analysis is a recognized scientometric method of classifying cited articles according to the frequency of which they have been referenced. The total number of citations an article receives is considered to reflect it's significance among it's peers. Until now, a bibliometric analysis has never been performed in the specialty of craniofacial anomalies and craniofacial surgery. This citation analysis generates an extensive list of the 50 most influential papers in this developing field. Journals specializing in craniofacial surgery, maxillofacial surgery, plastic surgery, neurosurgery, genetics and pediatrics were searched to demonstrate which articles have cultivated the specialty within the past 55 years. The results show an intriguing compilation of papers which outline the fundamental knowledge of craniofacial anomalies and the developments of surgical techniques to manage these patients. This citation analysis provides a summation of the current most popular trends in craniofacial literature. These esteemed papers aid to direct our decision making today within this specialty.

    2011-02-01

    We validate the use of archiving Internet references by comparing the accessibility of published uniform resource locators (URLs) with corresponding archived URLs over time. We scanned the "Articles in Press" section in Annals of Emergency Medicine from March 2009 through June 2010 for Internet references in research articles. If an Internet reference produced the authors' expected content, the Web page was archived with WebCite (http://www.webcitation.org). Because the archived Web page does not change, we compared it with the original URL to determine whether the original Web page had changed. We attempted to access each original URL and archived Web site URL at 3-month intervals from the time of online publication during an 18-month study period. Once a URL no longer existed or failed to contain the original authors' expected content, it was excluded from further study. The number of original URLs and archived URLs that remained accessible over time was totaled and compared. A total of 121 articles were reviewed and 144 Internet references were found within 55 articles. Of the original URLs, 15% (21/144; 95% confidence interval [CI] 9% to 21%) were inaccessible at publication. During the 18-month observation period, there was no loss of archived URLs (apart from the 4% [5/123; 95% CI 2% to 9%] that could not be archived), whereas 35% (49/139) of the original URLs were lost (46% loss; 95% CI 33% to 61% by the Kaplan-Meier method; difference between curves PWeb page at publication can help preserve the authors' expected information.

    2009-07-01

    Full Text Available The International Business Environment (IBE has been argued to be the essential context for international business (IB studies and the distinguishing factor from other management studies and studies of large enterprises. Two content analysis show that many papers published in top tier IB journals either lack reference to any dimension of the IBE or tend to be uni-or bi-dimensional when addressing the IBE; it is not a surprise that the cultural dimension is the most often used. We suggest that: (a there is need to developed more uni-and multi-dimensional environmental constructs; (ba more holistic view of the IBE provides richer insights on the actual complexity underlying IB research. Future studiesthat provide more comprehensive models of the IBE that overcome the usual broad classifications of the internationalenvironment as undefined and uncontrollable factors are warranted to advance conceptual and empirical research.

    2017-01-01

    Reference electrode standardization technique (REST) has been increasingly acknowledged and applied as a re-reference technique to transform an actual multi-channels recordings to approximately zero reference ones in electroencephalography/event-related potentials (EEG/ERPs) community around the world in recent years. However, a more easy-to-use toolbox for re-referencing scalp EEG data to zero reference is still lacking. Here, we have therefore developed two open-source MATLAB toolboxes for REST of scalp EEG. One version of REST is closely integrated into EEGLAB, which is a popular MATLAB toolbox for processing the EEG data; and another is a batch version to make it more convenient and efficient for experienced users. Both of them are designed to provide an easy-to-use for novice researchers and flexibility for experienced researchers. All versions of the REST toolboxes can be freely downloaded at http://www.neuro.uestc.edu.cn/rest/Down.html, and the detailed information including publications, comments and documents on REST can also be found from this website. An example of usage is given with comparative results of REST and average reference. We hope these user-friendly REST toolboxes could make the relatively novel technique of REST easier to study, especially for applications in various EEG studies.

  15. Classification of CITES-listed and other neotropical Meliaceae wood images using convolutional neural networks.

    2018-01-01

    The current state-of-the-art for field wood identification to combat illegal logging relies on experienced practitioners using hand lenses, specialized identification keys, atlases of woods, and field manuals. Accumulation of this expertise is time-consuming and access to training is relatively rare compared to the international demand for field wood identification. A reliable, consistent and cost effective field screening method is necessary for effective global scale enforcement of international treaties such as the Convention on the International Trade in Endagered Species (CITES) or national laws (e.g. the US Lacey Act) governing timber trade and imports. We present highly effective computer vision classification models, based on deep convolutional neural networks, trained via transfer learning, to identify the woods of 10 neotropical species in the family Meliaceae, including CITES-listed Swietenia macrophylla , Swietenia mahagoni , Cedrela fissilis , and Cedrela odorata . We build and evaluate models to classify the 10 woods at the species and genus levels, with image-level model accuracy ranging from 87.4 to 97.5%, with the strongest performance by the genus-level model. Misclassified images are attributed to classes consistent with traditional wood anatomical results, and our species-level accuracy greatly exceeds the resolution of traditional wood identification. The end-to-end trained image classifiers that we present discriminate the woods based on digital images of the transverse surface of solid wood blocks, which are surfaces and images that can be prepared and captured in the field. Hence this work represents a strong proof-of-concept for using computer vision and convolutional neural networks to develop practical models for field screening timber and wood products to combat illegal logging.

    Full Text Available Attribute selection is one of the steps before patent clustering. Various attributes can be used for clustering. In this study, the effect of using citation and citation title words, respectively, in form of bibliographic coupling and citation title words sharing, were measured and compared with each other, as patent attributes. This study was done in an experimental method, on a collection of 717 US Patent cited in the patents belong to 977/774 subclass of US Patent Classification. Fuzzy C-means was used for patent clustering and extended BCubed precision and extended BCubed recall were used as evaluation measure. The results showed that the clustering produced by bibliographic coupling had better performance than clustering used citation title words and existence of cluster structure were in a wider range of exhaustivity than citation title words.

    2001-06-01

    The objective with this report is to describe all the waste and the waste package that is expected to be deposited in SFR-1 at the time of closure. This report is a part of the SAFE project (Safety Assessment of Final Repository for Radioactive Operational Waste), i.e. the renewed safety assessment of SFR-1. The accounted waste inventory has been used as input to the release calculation that has been performed in the SAFE project. The waste inventory is based on an estimated operational lifetime of the Swedish nuclear power plants of 40 years and that closure of the SFR repository will happen in 2030. In the report, data about geometries, weights, materials, chemicals and radionuclide are given. No chemo toxic material has been identified in the waste. The inventory is based on so called waste types and the waste types reference waste package. The reference waste package combined with a prognosis of the number of waste packages to the year 2030 gives the final waste inventory for SFR-1. All reference waste packages are thoroughly described in the appendices of this report. The reference waste packages are as far as possible based on actual experiences and measurements. The radionuclide inventory is also based on actual measurements. The inventory is based on measurements of 60 Co and 137 Cs in waste packages and on measurements 239 Pu and 240 Pu in reactor water. Other nuclides in the inventory are calculated with correlation factors. In the SAFE project's prerequisites it was said that one realistic and one conservative (pessimistic) inventory should be produced. The conservative one should then be used for the release calculations. In this report one realistic and one conservative radionuclide inventory is presented. The conservative one adds up to 10 16 Bq. Regarding materials there is only one inventory given since it is not certain what is a conservative assumption

    Weight reduction that corresponds with lifestyle modification is difficult to foster. The theory of planned behaviour has been actively cited in explaining health-related behaviour. This review evaluated the application of the theory of planned behaviour to weight-loss behaviour. Among the three reviewed papers, cross-sectional survey designs and subjective outcome measurements were commonly applied. All of the studies recruited obese female adults as participants, limiting the generalisability of the studies' findings. The theory of planned behaviour can be effectively applied in weight-reduction programmes targeting female obese patients. This review confirmed critiques citing the limitations of experimental studies, the subjective measurement of behaviour and short follow-up periods.

    Maslow's need hierarchy and model of the self-actualizing personality are reviewed and criticized. The definition of self-actualization is found to be confusing, and the gratification of all needs is concluded to be insufficient to explain self-actualization. Therefore the theory is reconstructed on the basis of a second-order, cognitive-systemic framework. A hierarchy of basic needs is derived from the urgency of perturbations which an autonomous system must compensate in order to maintain i...

    Citation classics have been published in many fields of medicine; however, none have focused on interventional cardiology. The goal of this study was to identify the top 100 articles in the field of interventional cardiology and highlight their important trends and characteristics. The Scopus database was used by 2 independent reviewers to extract the top 100 articles using a variety of keywords. We found articles published between 1953 and 2012. Majority (n = 78) of the top 100 articles were published between 1996 and 2010, and the United States was affiliated with the highest number of articles in our list (n = 68). Over half (n = 54) the articles were funded. Private funding was correlated with higher citations (p = 0.036). A third (n = 33) of the papers had authors with conflicts of interest; however, conflict of interest had no effect on citations (p = 0.837). Majority (n = 57) of the articles studied coronary angioplasty and stenting; followed by coronary angiography (n = 14). Women were underrepresented, with only 11 female first authors in the top 100 papers, and only 1 female in the list of top authors who had 5 or more publications. In conclusion, the following features define the typical highly cited article in interventional cardiology-a clinical trial conducted in the United States, which studies angioplasty, and has been published relatively recently in a high-impact journal by a male first author.

    2013-01-01

    The present study examined the correspondence between perceived and actual social discrimination of overweight people. In total, 77 first-year students provided self-ratings about their height, weight, and perceived social inclusion. To capture actual social inclusion, each participant nominated those fellow students (a) she/he likes and dislikes and (b) about whom she/he is likely to hear social news. Students with lower Body Mass Index (BMI) felt socially included, irrespective of their actual social inclusion. In contrast, students with higher BMI felt socially included depending on the degree of their actual social inclusion. Specifically, their felt social inclusion accurately reflected whether they were actually liked/disliked, but only when they were part of social news. When not part of social news, they also showed insensitivity to their actual social inclusion status. Thus, students with a lower BMI tended to be insensitive, while students with a higher BMI showed a differential sensitivity to actual social discrimination.

    Full Text Available The Five-Factor Model of personality, which includes dimensions energy, agreeableness, conscientiousness, emotional stability, and openness, gained a growing acceptance by personality researchers. In the present study the actual personality characteristics of physical educators and the personality profile of an ideal (according to subjective evaluations of experts physical educator were investigated. The aim of the study was to examine differences between profiles of actual and preferred personality characteristics and to present differences in personality characteristics between male and female physical educators of different ages. The study included 76 (40 male, 36 female 24 to 58 year-old physical educators (mean age 39.7 years. 34 experts from the field of sport, physical education, and kinesiology evaluated the preferred personality structure of an ideal physical educator. The Big Five Observer (BFO was used to assess actual and preferred personality structures. These results show that the actual personality profile of physical educators is described with all five moderately high dimensions, which is relatively congruent with the social type from Holland's typology, characteristic of educators. In comparison with participants, an ideal physical educator should have equally expressed agreeableness, while other four dimensions should be highly expressed. Gender differences in energy and agreeableness (women have higher results in both dimensions were found significant. No significant age differences in the personality structure were obtained by a cross-sectional comparison.

    Adaptation of working environment (social, organizational, physical and physical) should assure higher level of workers' availability and consequently higher level of workers' performance. A special theoretical model for description of connections between environmental factors, human availability and performance was developed and validated. The central part of the model is evaluations of human actual availability in the real working situation or fitness for duties self-estimation. The model was tested in different working environments. On the numerous (2000) workers, standardized values and critical limits for an availability questionnaire were defined. Standardized method was used in identification of the most important impact of environmental factors. Identified problems were eliminated by investments in the organization in modification of selection and training procedures in humanization of working .environment. For workers with behavioural and health problems individual consultancy was offered. The described method is a tool for identification of impacts. In combination with behavioural analyses and mathematical analyses of connections, it offers possibilities to keep adequate level of human availability and fitness for duty in each real working situation. The model should be a tool for achieving adequate level of nuclear safety by keeping the adequate level of workers' availability and fitness for duty. For each individual worker possibility for estimation of level of actual fitness for duty is possible. Effects of prolonged work and additional tasks should be evaluated. Evaluations of health status effects and ageing are possible on the individual level. (author)

  7. Are Soil Pollution Risks Established by Governments the Same as Actual Risks?

    International Nuclear Information System (INIS)

    Reijnders, L.

    2010-01-01

    Though soil pollution policies in North America and the European Union increasingly use risk-based standards, the construction and application of such standards are often deficient in taking account of actual risks. Standards refer to total concentrations of substances and not to the biologically available amount. A number of countries neglect -background exposure, and assumptions regarding routes of exposure to soil pollution can be very different and at variance with empirical data. Recent dose-effect studies are neglected in a number of cases. The application of standards does not take account of the overall risk of soil pollution but rather leads to the decision whether or not there is violation of at least one standard for a specified (group of) substance(s). Standards for soil pollutants are often based on the assumption that only effect addition can occur, whereas dose addition, antagonism and synergism, and indirect effects may in fact apply. Several remedies for current shortcomings are proposed

    The Plastic Surgery In-Service Training Exam is a knowledge assessment tool widely used during plastic surgery training in the United States. This study analyzed literature supporting correct answer choices to determine highest yield sources, journal publication lag, and journal impact factors. Digital syllabi of 10 consecutive Plastic Surgery In-Service Training Exam administrations (2006 to 2015) were reviewed. The most-referenced articles, journals, and textbooks were determined. Mean journal impact factor and publication lag were calculated and differences were elucidated by section. Two thousand questions and 5386 references were analyzed. From 2006 to 2015, the percentage of journal citations increased, whereas textbook references decreased (p < 0.001). Plastic and Reconstructive Surgery was cited with greatest frequency (38.5 percent), followed by Clinics in Plastic Surgery (5.6 percent), Journal of Hand Surgery (American volume) (5.1 percent), and Annals of Plastic Surgery (3.8 percent). There was a trend toward less publication lag over the study period (p = 0.05), with a mean publication lag of 9.1 ± 9.0 years for all journal articles. Mean journal impact factor was 2.3 ± 4.3 and lowest for the hand and lower extremity section (1.7 ± 2.8; p < 0.001). The highest yield textbooks were elucidated by section. Plastic surgery faculty and residents may use these data to facilitate knowledge acquisition during residency.

    This report presents the results of questionnaire survey for actual conditions of radiation therapy, which was conducted with the aim of establishing the standardization of radiation therapy techniques. Questionnaires were sent to 100 facilities in Japan, and 86 of these answered, consisting of 62 university hospitals, 2 national hospitals, 14 cancer centers, 4 prefectural or municipal hospitals, and 4 other hospitals. In addition to electron beam therapy, the following typical diseases for radiation therapy were selected as standard irradiation models: cancers of the larynx, esophagus, breast, and uterine cervix, and malignant lymphomas. According to these models, questionnaire results are analyzed in terms of the following four items: (1) irradiation procedures, (2) energy used for radiotherapy, (3) the depth for calculating target absorption doses, and (4) points for displaying target absorption doses.

    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.

It is associated with adverse perinatal outcomes such as premature delivery and stillbirth. Mild OC is defined as SBA levels of 10-39 mumol\\/l, and severe OC is defined by levels >40 mumol\\/l. SBA levels in normal pregnancy have not been investigated. We aimed to establish reference values for SBA in healthy pregnant women across different trimesters of pregnancy. Design Cross-sectional analysis of SBA levels. Setting A large tertiary referral university teaching maternity hospital. Population Healthy pregnant women with a singleton pregnancy and a body mass index (BMI) < 40, excluding women with significant alcohol intake, history of liver disease, prior cholecystectomy and OC. Methods Cross-sectional analysis of SBA levels at 12, 20, 28 and 36 weeks of gestation, and on days 1-3 postpartum. Main outcome measures SBA levels in mumol\\/l. Results A total of 219 women attending for antenatal care were recruited, and SBA levels were assayed at 12, 20, 28 and 36 weeks of gestation, and up to 72 hours postpartum (n = 44-49 cases at each stage). The majority were white European women, with a median age of 30 years (range 17-46 years) and median BMI of 25 (range 18-38). Values of SBA ranged from 0.3 to 9.8 mumol\\/l in 216 women, with only three measurements outside this range. There were no significant changes throughout pregnancy. Conclusions SBA values in uncomplicated pregnancies are consistent, regardless of gestation, and are not elevated in pregnancy. The current reference values for the diagnosis of OC appear to be appropriate.

  14. Bacteriophage prehistory: Is or is not Hankin, 1896, a phage reference?

    We identified 30 actual or presumptive "bacteriophage" references dating between the years 1895 and 1917 and have further explored one of the oldest: Hankin's 1896 study of a bactericidal action associated with the waters of the Ganges and Jumna rivers in India. As Hankin's work took place approximately 20 years prior to the actual discovery of bacteriophages, no claims were made as to a possible phage nature of the phenomenon. Here we suggest that it may be imprudent to assume nevertheless that it represents an early observation of phagemediated bactericidal activity. Our principal argument is that the antibacterial aspect of these river waters was able to retain full potency following "heating" for one-half hour in hermetically sealed tubes, where heating in "open" tubes resulted in loss of antibacterial activity. We also suggest that environmental phage counts would have had to have been unusually high-greater than 10(6)/ml impacting a single host strain-to achieve the rates of bacterial loss that Hankin observed.

    CITES is a 35-year-old convention with a current total of 175 signatories, or parties. It regulates international trade in live specimens and products of more than 30,000 animal and plant species under three different trade regimes. CITES has clearly proved its importance for nature conservation, but its regulations often are difficult to implement and enforce, leading to unacceptably high levels of unsustainable and illegal trade in many wildlife species. There are ways, however, to improve the situation and to make compliance with CITES regulations both easier and more attractive. Copyright © 2011 Central Police University.

  16. How serious of a problem is staff turnover in substance abuse treatment? A longitudinal study of actual turnover.

    In the substance abuse treatment field, the annual turnover rate is cited as being anywhere between 19% and 50% (J.A. Johnson & P.M. Roman, 2002; S.L. Gallon, R.M. Gabriel, J.R.W. Knudsen, 2003; H.K. Knudsen, J.A. Johnson, & P.M. Roman, 2003; A.T. McLellan, D. Carise, & H.D. Kleber, 2003). However, no research to date has evaluated these claims by tracking turnover longitudinally using organizational turnover data from substance abuse treatment centers. This research presents the results of a longitudinal study designed to systematically examine actual turnover among counselors and clinical supervisors. Twenty-seven geographically dispersed treatment organizations, serving a wide range of clients in the public and private sector, provided data for the study over a 2-year time span (2008-2009). The annual turnover rate was 33.2% for counselors and 23.4% for clinical supervisors. For both groups, the majority of turnover was voluntary (employee-initiated). Specific reasons for turnover were largely consistent across the two groups, with the most common reason being a new job or new opportunity. The findings are discussed in terms of the unique employment context of substance abuse treatment. Practical recommendations are also discussed to help stem the tide of turnover in the field of substance abuse treatment. Copyright (c) 2010 Elsevier Inc. All rights reserved.

  17. Changes in the referent body location and configuration may underlie human gait, as confirmed by findings of multi-muscle activity minimizations and phase resetting.

    Locomotion is presumably guided by feed-forward shifts in the referent body location in the desired direction in the environment. We propose that the difference between the actual and the referent body locations is transmitted to neurons that virtually diminish this difference by appropriately changing the referent body configuration, i.e. the body posture at which muscles reach their recruitment thresholds. Muscles are activated depending on the gap between the actual and the referent body configurations resulting in a step being made to minimize this gap. This hypothesis implies that the actual and the referent leg configurations can match each other at certain phases of the gait cycle, resulting in minimization of leg muscle activity. We found several leg configurations at which EMG minima occurred, both during forward and backward gait. It was also found that the set of limb configurations associated with EMG minima can be changed by modifying the pattern of forward and backward gait. Our hypothesis predicts that, in response to perturbations of gait, the rate of shifts in the referent body location can temporarily be changed to avoid falling. The rate influences the phase of rhythmic limb movements during gait. Therefore, following the change in the rate of the referent body location, the whole gait pattern, for all four limbs, will irreversibly be shifted in time (long-lasting and global phase resetting) with only transient changes in the gait speed, swing and stance timing and cycle duration. Aside from transient changes in the duration of the swing and/or stance phase in response to perturbation, few previous studies have documented long-lasting and global phase resetting of human gait in response to perturbation. Such resetting was a robust finding in our study. By confirming the notion that feed-forward changes in the referent body location and configuration underlie human locomotion, this study solves the classical problem in the relationship between

    As an important technology for shortening the construction period and reducing the cost of nuclear power project, modular technology has become one of the development orientations of the third generation nuclear power plant. Taking CPR1000 nuclear power reactor as reference plant and drawing on advanced foreign technology of modularization, the overall concept design has been completed with the help of the self-developed 3D modular design system. On this basis, a typical detailed design work has been carried out so as to verify the feasibility of technology. Besides, an analysis on implementation of modular technology has been made from two aspects (procurement and construction), and the feasibility of research results in actual project has been evaluated. It provides references for the promotion of self-reliant modular technology in nuclear power project in China. (authors)

  19. Actual heating energy savings in thermally renovated Dutch dwellings

    The register of the Dutch social housing stock was analysed, containing 300.000 dwellings, renovated between 2010 and 2013. The main objective was twofold: to evaluate the performance gap in these dwellings before and after the renovation and to establish what renovation measures achieve the highest reduction of consumption, particularly in practice (actual savings). The results showed large performance gaps in dwellings with low R and high U values, local heating systems, changes from a non-condensing into a condensing boiler and upgrades to a natural ventilation system. Regarding the actual effectiveness of renovation measures, replacement of old gas boilers with more efficient ones yields the highest energy reduction, followed by deep improvements of windows. Installing mechanical ventilation yields a small reduction compared to other measures, but still much larger than theoretically expected. The paper shows once more that the calculation method currently in use cannot be considered accurate if compared to actual consumption. The study demonstrated that unrealistic theoretical efficiencies of heating systems and insulation values are causing a part of the performance gap. Nowadays, large datasets of buildings thermal performance and actual consumption offer an opportunity to improve these misconceptions. - Highlights: • Performance gap is lower in more efficient buildings. • Replacements of gas boilers – the most energy reduction among renovation measures. • Replacing the ventilation system yields a much larger reduction than expected. • How well are the standard values of the calculation methods defined? • Provide large public building performance databases including actual use data.

    Routine blood tests are an integral part of clinical medicine and in interpreting blood test results clinicians have two broad options. (1) Dichotomise the blood tests into normal/abnormal or (2) use the actual values and overlook the reference values. We refer to these as the "binary" and the "non-binary" strategy respectively. We investigate which strategy is better at predicting the risk of death in hospital based on seven routinely undertaken blood tests (albumin, creatinine, haemoglobin, potassium, sodium, urea, and white blood cell count) using tree models to implement the two strategies. A retrospective database study of emergency admissions to an acute hospital during April 2009 to March 2010, involving 10,050 emergency admissions with routine blood tests undertaken within 24 hours of admission. We compared the area under the Receiver Operating Characteristics (ROC) curve for predicting in-hospital mortality using the binary and non-binary strategy. The mortality rate was 6.98% (701/10050). The mean predicted risk of death in those who died was significantly (p-value non-binary strategy (risk = 0.222 95%CI: 0.194 to 0.251), representing a risk difference of 28.74 deaths in the deceased patients (n = 701). The binary strategy had a significantly (p-value non-binary strategy (0.853 95% CI: 0.840 to 0.867). Similar results were obtained using data from another hospital. Dichotomising routine blood test results is less accurate in predicting in-hospital mortality than using actual test values because it underestimates the risk of death in patients who died. Further research into the use of actual blood test values in clinical decision making is required especially as the infrastructure to implement this potentially promising strategy already exists in most hospitals.

    A number of organic and inorganic exchangers are being developed and evaluated for cesium removal from Hanford tank wastes. The exchangers of interest that are investigated in this work include powdered (IONSIV reg-sign IE-910; referred to as IE-910) and engineered (IONSIV reg-sign IE-911; referred to as IE-911) forms of the crystalline silico-titanate (CST) inorganic sorbent developed by Sandia National Laboratories (SNL)/Texas A and M and prepared by UOP; a phenol-formaldehyde (CS-100) resin developed by Rohm and Haas; a resorcinol-formaldehyde (R-F) polymer developed at the Westinghouse Savannah River Company (WSRC) and produced by Boulder Scientific; an inorganic zeolite exchanger produced by UOP (IONSIV reg-sign TIE-96; referred to as TIE-96); an inorganic sodium titanate produced by Allied Signal/Texas A and M (NaTi); and a macrocyclic organic resin developed and produced by IBC Advanced Technologies (SuperLig reg-sign 644; referred to as SL-644). Several of these materials are still under development and may not be in the optimal form. The work described in this report involves the direct comparison of the ion exchange materials for the pretreatment of actual and simulated Hanford tank waste. Data on the performance of all of the exchangers with simulated and actual double shell slurry feed (DSSF) is included. The DSSF waste is a mixture of the supernate from tanks 101-AW (70%), 106-AP (20%) and 102-AP (10%). The comparative parameters include radionuclide removal efficiency under a variety of conditions and material properties (e.g., bed density and percent removable water). Cesium and strontium distribution (K d ), lambda (λ = K d x ρ b ), and decontamination factors (DF) are compared as a function of exchanger contact duration, solution composition (Na and Cs concentration), exchanger/waste phase ratio, and multiple sequential contacts

    Residential thermostats have been a key element in controlling heating and cooling systems for over sixty years. However, today's modern programmable thermostats (PTs) are complicated and difficult for users to understand, leading to errors in operation and wasted energy. Four separate tests of usability were conducted in preparation for a larger study. These tests included personal interviews, an on-line survey, photographing actual thermostat settings, and measurements of ability to accomplish four tasks related to effective use of a PT. The interviews revealed that many occupants used the PT as an on-off switch and most demonstrated little knowledge of how to operate it. The on-line survey found that 89% of the respondents rarely or never used the PT to set a weekday or weekend program. The photographic survey (in low income homes) found that only 30% of the PTs were actually programmed. In the usability test, we found that we could quantify the difference in usability of two PTs as measured in time to accomplish tasks. Users accomplished the tasks in consistently shorter times with the touchscreen unit than with buttons. None of these studies are representative of the entire population of users but, together, they illustrate the importance of improving user interfaces in PTs.

    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.

  12. Cesium ion exchange using actual waste: Column size considerations

    International Nuclear Information System (INIS)

    Brooks, K.P.

    1996-04-01

    It is presently planned to remove cesium from Hanford tank waste supernates and sludge wash solutions using ion exchange. To support the development of a cesium ion exchange process, laboratory experiments produced column breakthrough curves using wastes simulants in 200 mL columns. To verify the validity of the simulant tests, column runs with actual supernatants are being planned. The purpose of these actual waste tests is two-fold. First, the tests will verify that use of the simulant accurately reflects the equilibrium and rate behavior of the resin compared to actual wastes. Batch tests and column tests will be used to compare equilibrium behaviors and rate behaviors, respectively. Second, the tests will assist in clarifying the negative interactions between the actual waste and the ion exchange resin, which cannot be effectively tested with simulant. Such interactions include organic fouling of the resin and salt precipitation in the column. These effects may affect the shape of the column breakthrough curve. The reduction in column size also may change the shape of the curve, making the individual effects even more difficult to sort out. To simplify the evaluation, the changes due to column size must be either understood or eliminated. This report describes the determination of the column size for actual waste testing that best minimizes the effect of scale-down. This evaluation will provide a theoretical basis for the dimensions of the column. Experimental testing is still required before the final decision can be made. This evaluation will be confined to the study of CS-100 and R-F resins with NCAW simulant and to a limited extent DSSF waste simulant. Only the cesium loading phase has been considered

    Full Text Available The aim of this study was to know and understand the re-actualization of bale banjar function in Denpasar City. This study was conducted due to the imbalance between the assumptions and current reality. The data sources of this study were some bale banjar-s in Denpasar City, related informants, and previous research findings. All data were collected using observation, interviews, and literature studies techniques and were analyzed using sociocultural evolution, community rationalization, and commodification theories. The research findings showed that re-actualization of bale banjar function in Denpasar City happened due to the high demand of economic space of capitalist economy and the changes of local society’s way of thinking; re-actualization of bale banjar’s form in Denpasar City could be seen from the changes in style and appearance of the spaces that are now widely designed into two floors. The society used the upper floors as a gathering place and the lower floors are rented as a center of economic activity; re-actualization of bale banjar function in Denpasar City had the implications on the way of thinking, the conception of bale banjar form and function and material culture such as the weakening of social relations among krama banjar.

  16. The environmental cost of a reference withdrawal from surface waters: Definition and geography

    Soligno, Irene; Ridolfi, Luca; Laio, Francesco

    2017-12-01

    World freshwater ecosystems are significantly deteriorating at a faster rate than other ecosystems. Water withdrawals are recognized as one of the main drivers of growing water stress in river basins worldwide. Over the years, much effort has been devoted to quantify water withdrawals at a global scale; however, comparisons are not simple because the uneven spatiotemporal distribution of surface water resources entails that the same amount of consumed water does not have the same environmental cost in different times or places. In order to account for this spatiotemporal heterogeneity, this work proposes a novel index to assess the environmental cost of a withdrawal from a generic river section. The index depends on (i) the environmental relevance of the impacted fluvial ecosystem (e.g., bed-load transport capacity, width of the riparian belt, biodiversity richness) and (ii) the downstream river network affected by the water withdrawal. The environmental cost has been estimated in each and every river section worldwide considering a reference withdrawal. Being referred to a unitary reference withdrawal that can occur in any river section worldwide, our results can be suitably arranged for describing any scenario of surface water consumption (i.e., as the superposition of the actual pattern of withdrawals). The index aims to support the interpretation of the volumetric measure of surface water withdrawal with a perspective that takes into account the fluvial system where the withdrawal actually occurs. The application of the index highlights the river regions where withdrawals can cause higher environmental costs, with the challenge of weighting each water withdrawal considering the responsibilities that it has on downstream freshwater ecosystems.

    Mental chronometry, commonly used to evaluate motor imagery ability, measures the imagined time required for movements. Previous studies investigating mental chronometry of walking have investigated healthy older adults. However, mental chronometry in frail older adults has not yet been clarified. To investigate temporal characteristics of imagined and actual walking in frail older adults. We investigated the time required for imagined and actual walking along three walkways of different widths [width(s): 50, 25, 15 cm × length: 5 m] in 29 frail older adults and 20 young adults. Imagined walking was measured with mental chronometry. We observed significantly longer imagined and actual walking times along walkways of 50, 25, and 15 cm width in frail older adults compared with young adults. Moreover, temporal differences (absolute error) between imagined and actual walking were significantly greater in frail older adults than in young adults along walkways with a width of 25 and 15 cm. Furthermore, we observed significant differences in temporal differences (constant error) between frail older adults and young adults for walkways with a width of 25 and 15 cm. Frail older adults tended to underestimate actual walking time in imagined walking trials. Our results suggest that walkways of different widths may be a useful tool to evaluate age-related changes in imagined and actual walking in frail older adults.

  18. Missing citations due to exact reference matching: Analysis of a random sample from WoS. Are publications from peripheral countries disadvantaged?

    Energy Technology Data Exchange (ETDEWEB)

    Donner, P.

    2016-07-01

    Citation counts of scientific research contributions are one fundamental data in scientometrics. Accuracy and completeness of citation links are therefore crucial data quality issues (Moed, 2005, Ch. 13). However, despite the known flaws of reference matching algorithms, usually no attempts are made to incorporate uncertainty about citation counts into indicators. This study is a step towards that goal. Particular attention is paid to the question whether publications from countries not using basic Latin script are differently affected by missed citations. The proprietary reference matching procedure of Web of Science (WoS) is based on (near) exact agreement of cited reference data (normalized during processing) to the target papers bibliographical data. Consequently, the procedure has near-optimal precision but incomplete recall - it is known to miss some slightly inaccurate reference links (Olensky, 2015). However, there has been no attempt so far to estimate the rate of missed citations by a principled method for a random sample. For this study a simple random sample of WoS source papers was drawn and it was attempted to find all reference strings of WoS indexed documents that refer to them, in particular inexact matches. The objective is to give a statistical estimate of the proportion of missed citations and to describe the relationship of the number of found citations to the number of missed citations, i.e. the conditional error distribution. The empirical error distribution is statistically analyzed and modelled. (Author)

The most influential consideration for referral was the scientific merit of the study, followed by patient benefit. Contextual factors and physician compensation were identified as the least important reasons pediatricians refer patients to research. Analyses also revealed significant relationships between referrals made and percentage of time spent in research activities.Conclusions: Pediatricians may be more likely to refer their patients to clinical research studies when they believe the purpose of the study is meaningful to patients as well as to future patient populations. In addition, characteristics of the individual pediatricians may play an important role in actual referral behavior.Keywords: recruitment, clinical research, adolescent research, pediatrician attitudes

    Full Text Available The article is dedicated to the research of youth subculture members’ self-actualization (role-playing movement as an example. It describes certain characteristics of role-players’ self-actualization, its structure, and also its gender and age specific features. It has been proven that the level of self-actualization of the members of the role-playing movement is higher than of the people who are not interested in it and that taking part in role-playing games is a more significant factor for the self-actualization of the personality than the gender and age of the players.

    Children's perception of their own motor competence is an important correlate of their actual motor competence. The current study is the first to examine this association in British children and the first to use both product and process measures of actual motor competence. A total of 258 children (139 boys and 119 girls; aged 4 to 7 years, Mean = 5.6, SD = .96) completed measures of self-perceived motor competence using the Pictorial Scale for Perceived Movement Competence in Young Children. Children were classified as "Low," "Medium," or "High" perceived competence based on tertile analysis. Actual motor competence was assessed with the Test of Gross Motor Development-2 (a process measure) and a composite of 10-m sprint run time, standing long jump distance, and 1-kg seated medicine ball throw (collectively, a product measure). Data for process and product measures were analyzed using a 2 (sex) × 3 (high, medium, low perceived competence) analysis of covariance, with body mass index, calculated from height and mass, and age controlled. Boys obtained significantly higher scores than girls for both the process ( p = .044) and product ( p = .001) measures of actual motor competence. Boys had significantly ( p = .04) higher scores for perceived competence compared to girls. Compared to children classified as medium and high self-perceived competence, children classified as low self-perceived competence had lower process ( p = .001) and product scores (i.e., medium, p = .009 and high, p = .0001) of actual motor competence. Age ( p = .0001) and body mass index ( p = .0001) were significantly associated with product motor competence. Strategies to enhance actual motor competence may benefit children's self-perceived motor competence.

    Aim To assess the impact of the generic reference pricing (GRP) system on the prices and cost of medicines in Slovenia approximately 8 years after its introduction in 2003 and before the implementation of the therapeutic reference pricing system. Methods A retrospective study of all medicines (N = 789) included in the GRP system on January 31, 2012 was performed. Medicine prices and cost were analyzed between January 31, 2012 and December 31, 2013 after every update (N = 11) of the maximum reimbursable price (MRP) and were compared to the price and cost on January 31, 2012 (index date). Time trends of different types of medicine prices (maximum allowed price, MRP, and actual wholesale price) were graphically analyzed, and actual wholesale price adjustments to the MRP changes and the budget impact of the GRP were assessed. Results In the 2-year study period, the long-term performance of the GRP system was associated with an approximate 45% decrease in the average MRP or an approximate 20% cost reduction. For each MRP update period, the GRP reduced the cost based on the maximum allowed price for approximately 30%. The wholesale price adjustments were mostly made for medicines priced above the MRP and reduced patients’ out-of-pocket cost. Conclusions In the long term, the GRP system effectively reduced medicine prices and the cost of reimbursed products. PMID:29740992

  6. [Assessment of actual benefits of new drugs by the Transparency Committee].

    Le Jeunne, C

    2008-01-01

    When a drug has been granted a marketing authorization, if the pharmaceutical company wants it to be covered by the National Health Insurance, the company has to submit a file with all the studies concerning the drug, especially drug-drug comparative studies, to be assessed by the Transparency Committee. Drugs are assessed on two criteria: actual or expected benefit (AB) and improvement in actual benefit (IAB). Actual benefit mainly takes into account the severity of the disease concerned, the level of efficacy relative to known side effects (risk-benefit ratio), and the place the drug is intended to take in the therapeutic strategy. At the end of the assessment, AB is considered as important, moderate, poor or insufficient (to justify inclusion of the drug on the list of products to be reimbursed). After actual benefit is determined, improvement of actual benefit is assessed, comparing the estimated benefit of this drug with one of drugs with the same indication that is already reimbursed, to assess whether this drug will improve the patient's disease. This can be assessed by direct comparison (two drugs compared in the same clinical trial) or by indirect comparison (separate studies with the same design). There are four levels of added value, from I (major improvement) to IV (minor improvement). Level V represents no improvement. This second assessment is always relative to another drug. It never provides an absolute score. However, IAB is very important for pharmaceutical companies, because it is a fundamental criterion to determine the price of the drug, which is discussed with the Economic Committee of Health Products in a final phase. Actual benefit and improvement in actual benefit are allocated for each indication of a drug.

    This paper describes the use of certified reference materials to monitor the long-term quality of radiochemical separations. The practical limitations which determine the actual design of the quality control are discussed. The hypothesis that the high yield of the radiochemical separation will be constant with time has been checked and validated for the elements Zn, Fe, Co, Cd, Mo and to a lesser extent for W and Th using NBS SRM 1577A, BCR CRM 274 and IAEA RM A-11. This validation could not be made for the elements Cr, Au, and Ag. Especially for Cr there is a serious lack of appropiate certified reference materials. (orig.)

    The reference source system is a key factor to ensure the successful location of the satellite interference source. Currently, the traditional system used a mechanical rotating antenna which leaded to the disadvantages of slow rotation and high failure-rate, which seriously restricted the system’s positioning-timeliness and became its obvious weaknesses. In this paper, a multi-beam antenna scheme based on the horn array was proposed as a reference source for the satellite interference location, which was used as an alternative to the traditional reference source antenna. The new scheme has designed a small circularly polarized horn antenna as an element and proposed a multi-beamforming algorithm based on planar array. Moreover, the simulation analysis of horn antenna pattern, multi-beam forming algorithm and simulated satellite link cross-ambiguity calculation have been carried out respectively. Finally, cross-ambiguity calculation of the traditional reference source system has also been tested. The comparison between the results of computer simulation and the actual test results shows that the scheme is scientific and feasible, obviously superior to the traditional reference source system.

    Full Text Available The article considers the issues of a personality’s self-realization and self-actualization under current educational standards required in the time of impetuous development in informative technologies. The practical aspect of the article describes self-realization and self-actualization of a person as their social and useful activity, interdiscipline approach, it is characterised by interdependence of an individual and their social environment apart with the self-realization of a personality in educational process. Evidently, being a substantial ca-tegory of vital «self-assertion», it should be thought over in categories of self-actualization and self-realization. So, self-realization is considered to be a social process which continues all conscientious life. In pedagogics of our country, labour and professional activity were the spheres of self-actualization therefore, it should be taken into account external factors for self-realization and self-actualization of a person. If socio-pedagogic conditions presuppose having good teachers, what conditions should be created in an individual’s micro-groups and in particular, in the family and kind of values shoud an individual get through the process of socialization. Thus, technological project of self-realization of a personality has to assume that there is the strive for self-perfection and interrelation of ways of self-realization, self-education, and adaptation. The correlation of these ways in a specific educational field is the purpose of the article.

    Full Text Available The present studies address two criticisms of the theory of evolved sex differences in jealousy: (a that the sex difference in jealousy emerges only in response to hypothetical infidelity scenarios, and (b that the sex difference emerges only using forced-choice measures. In two separate studies, one a paper-and-pencil survey with a student sample and the other a web-based survey targeting a non-student sample, men and women showed significant sex differences in jealousy in response to actual infidelity experiences; men experienced more jealousy in response to the sexual aspects of an actual infidelity, whereas women experienced more jealousy in response to the emotional aspects of the infidelity. Sex differences emerged using both continuous measures of jealousy as well as the traditional forced-choice measure. Overall, our results demonstrate that sex differences in jealousy are not limited to responses to hypothetical infidelity scenarios; they also emerge in response to actual infidelity experiences.

    Chlorpyrifos is an anticholinesterase organophosphate insecticide widely used in Argentina in the production of food derived from animal, fruit and horticultural origin and is reported as a residue within these products. Local reference values for acetyl and butyrylcholinesterase were determined in Aberdeen Angus bovine and cross bred cattle (n = 25), a requirement to be able to evaluate toxicity of commercial organophosphate and carbamate formulations. The activity of cholinesterase enzymes presented an overall mean of 2,183.00 ± 485.6 IU L -1 for erythrocyte acetylcholinesterase and 203.1 ± 42.06 IU L -1 for plasma butyrylcholinesterase, which are used as reference values for meat steers within a system of intensive production in a semi-arid region. The toxic potential of chlorpyrifos in steers of the same breeds (n = 12) was assessed applying chlorpyrifos 15.00% Tipertox® in a single therapeutic dose of 7.50 mg kg -1 by topical route. Prior to application and then on day 1 and day 21 post-application, both blood cholinesterases, serum chlorpyrifos concentration by ultra-high resolution liquid chromatography with mass detector, analysis of blood counts, total proteins, liver enzymes, urea and creatinine were evaluated. The mean plasma concentration of chlorpyrifos was 27.90 ug L -1 at 24 h. The findings indicate that the therapeutic treatment of castrated male bovines treated with chlorpyrifos, applied by pour-on according to the manufacturer's instructions, does not cause changes in the variables evaluated.

    The brain can use multiple reference frames to code line orientation, including head-, object-, and gravity-centered references. If these frames change orientation, their representations must be updated to keep register with actual line orientation. We tested this internal updating during head rotation in roll, exploiting the rod-and-frame effect: The illusory tilt of a vertical line surrounded by a tilted visual frame. If line orientation is stored relative to gravity, these distortions should also affect the updating process. Alternatively, if coding is head- or frame-centered, updating errors should be related to the changes in their orientation. Ten subjects were instructed to memorize the orientation of a briefly flashed line, surrounded by a tilted visual frame, then rotate their head, and subsequently judge the orientation of a second line relative to the memorized first while the frame was upright. Results showed that updating errors were mostly related to the amount of subjective distortion of gravity at both the initial and final head orientation, rather than to the amount of intervening head rotation. In some subjects, a smaller part of the updating error was also related to the change of visual frame orientation. We conclude that the brain relies primarily on a gravity-based reference to remember line orientation during head roll.

  17. Weight Loss Composition is One-Fourth Fat-Free Mass: A Critical Review and Critique of This Widely Cited Rule

    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

    The article traces the sources of the three most widespread quotations attributed to Freud "What does Woman want?", "To love and to work" (summarizing what a psychological healthy person should be able to do well), and "Sometimes a cigar is just a cigar". The first could have been spoken by Freud pretty much as we have it. The second was possibly said by Freud, in some form vaguely resembling the currently cited version. The third most probably did not come from him in any form.

    Full Text Available Roaming reference service was pursued as a way to address declining reference statistics. The service was staffed by librarians armed with iPads over a period of six months during the 2010-2011 academic year. Transactional statistics were collected in relation to query type (Research, Facilitative or Technology, location and approach (librarian to patron, patron to librarian or via chat widget. Overall, roaming reference resulted in an additional 228 reference questions, 67% (n=153 of which were research related. Two iterations of the service were implemented, roaming reference as a standalone service (Fall 2010 and roaming reference integrated with traditional reference desk duties (Winter 2011. The results demonstrate that although the Weller Library’s reference transactions are declining annually, they are not disappearing. For a roaming reference service to succeed, it must be a standalone service provided in addition to traditional reference services. The integration of the two reference models (roaming reference and reference desk resulted in a 56% decline in the total number of roaming reference questions from the previous term. The simple act of roaming has the potential to reinvigorate reference services as a whole, forcing librarians outside their comfort zones, allowing them to reach patrons at their point of need.

  2. From preferred to actual mate characteristics: the case of human body shape.

    Directory of Open Access Journals (Sweden)

    Alexandre Courtiol

    Full Text Available The way individuals pair to produce reproductive units is a major factor determining evolution. This process is complex because it is determined not only by individual mating preferences, but also by numerous other factors such as competition between mates. Consequently, preferred and actual characteristics of mates obtained should differ, but this has rarely been addressed. We simultaneously measured mating preferences for stature, body mass, and body mass index, and recorded corresponding actual partner's characteristics for 116 human couples from France. Results show that preferred and actual partner's characteristics differ for male judges, but not for females. In addition, while the correlation between all preferred and actual partner's characteristics appeared to be weak for female judges, it was strong for males: while men prefer women slimmer than their actual partner, those who prefer the slimmest women also have partners who are slimmer than average. This study therefore suggests that the influences of preferences on pair formation can be sex-specific. It also illustrates that this process can lead to unexpected results on the real influences of mating preferences: traits considered as highly influencing attractiveness do not necessarily have a strong influence on the actual pairing, the reverse being also possible.

    2001-01-01

    This work was performed to investigate the actual exposure levels of the patients submitted to fluoroscopic procedures in diagnostic radiology. The data will be useful for a baseline in the establishment of local reference levels for fluoroscopic procedures, as recommended by the European Commission and IAEA. At present time there are no internationally accepted definitions for references levels for fluoroscopic complex procedures. Dose-area product (DAP) meters were employed in a pilot survey expressing the radiation exposures in terms of this quantity. This class of instrumentation has not yet been employed in Brazil. Parameters recorded were radiographic technique, fluoroscopy time, number of images, fluoroscopic and radiographic field sizes and DAPs. For fluoroscopy practice, a reference parameters set is recommended, instead of one diagnostic reference level. High patient exposures were found, calling for joined actions of health authorities, physicians, medical physicists, technicians and manufacturers. Monitoring of patient exposure, optimizing the radiation protection and establishing quantitative assessments of the exposition to the population in Brazil in this kind of procedure is important.

    2008-01-01

    This study provides an overview of the research performance of major European countries in the field Oncology, the most important journals in which they published their research articles, and the most important academic institutions publishing them. The analysis was based on Thomson Scientific's Web of Science (WoS) and calculated bibliometric indicators of publication activity and actual citation impact. Studying the time period 2000-2006, it gives an update of earlier studies, but at the same time it expands their methodologies, using a broader definition of the field, calculating indicators of actual citation impact, and analysing new and policy relevant aspects. Findings suggest that the emergence of Asian countries in the field Oncology has displaced European articles more strongly than articles from the USA; that oncologists who have published their articles in important, more general journals or in journals covering other specialties, rather than in their own specialist journals, have generated a relatively high actual citation impact; and that universities from Germany, and--to a lesser extent--those from Italy, the Netherlands, UK, and Sweden, dominate a ranking of European universities based on number of articles in oncology. The outcomes illustrate that different bibliometric methodologies may lead to different outcomes, and that outcomes should be interpreted with care.

Synergies were analyzed at the thumb-virtual finger (VF) level (VF is an imaginary digit with the mechanical action equivalent to that of the four actual fingers) and at the individual finger level. The subjects performed very quick vertical movements of a handle into a target. A load could be attached off-center to provide a pronation or supination torque. In a few trials, the handle was unexpectedly fixed to the table and the digits slipped off the sensors. In such trials, the hand stopped at a higher vertical position and rotated into pronation or supination depending on the expected torque. The aperture showed non-monotonic changes with a large, fast decrease and further increase, ending up with a smaller distance between the thumb and the fingers as compared to unperturbed trials. Multi-digit synergies were quantified using indices of co-variation between digit forces and moments of force across unperturbed trials. Prior to the lifting action, high synergy indices were observed at the individual finger level while modest indices were observed at the thumb-VF level. During the lifting action, the synergies at the individual finger level disappeared while the synergy indices became higher at the thumb-VF level. The results support the basic premise that, within a given task, setting a referent configuration may be described with a few referent values of variables that influence the equilibrium state, to which the system is attracted. Moreover, the referent configuration hypothesis can help interpret the data related to the trade-off between synergies at different hierarchical levels.

    Abt, Helmut A.

    2018-07-01

    Of 4000 papers published in astronomy and in physics in the past 40 years, 40.3%, and 23.4%, respectively, have not been cited (referenced). However, if we limit this to the final research papers (excluding announcements, book reviews, proposals for funding, and observing time, obituaries, etc.), the fractions are 1.4% and 1.5%, respectively. So virtually all the papers in these two sciences are useful. These data also tell us that the productivities of astronomers peak at age 40.4 years. and that 43.0% were published after the age of 50 years. For physicists, the peak occurs at 36.6 years. and only 33.7% were published after the age of 50 years. Therefore physicists peak about four years earlier than astronomers and they produce 9% fewer citations after the age of 50 years.

    1993-01-01

    We analyzed 105 case reports published in The Journal of the Korean Radiological Society between 1975 and 1985. The objectives of this studies were to find out (1) whether those case reports were truly original or not as far as domestic publications were concerned and (2) whether their citations of domestic literatures were correct. In two papers, we found previous reports published already in the domestic journal in spite of the authors' claim as their 'first case reports'. In 105 case reports, only 94 references were cited while 151 omitted. It is concluded that a case report must include a statement to authentically clarify whether similar report had been previously published through meticulous review of published literatures. We also recommend to computerize the index of domestic literatures

    2018-05-01

    Full Text Available Background: Draft and complete genome sequences from bacteria are key tools to understand genetic determinants involved in pathogenesis in several disease models. Piscirickettsia salmonis is a Gram-negative bacterium responsible for the Salmon Rickettsial Syndrome (SRS, a bacterial disease that threatens the sustainability of the Chilean salmon industry. In previous reports, complete and draft genome sequences have been generated and annotated. However, the lack of transcriptome data underestimates the genetic potential, does not provide information about transcriptional units and contributes to disseminate annotation errors. Results: Here we present the draft genome and transcriptome sequences of four P. salmonis strains. We have identified the transcriptional architecture of previously characterized virulence factors and trait-specific genes associated to cation uptake, metal efflux, antibiotic resistance, secretion systems and other virulence factors. Conclusions: This data has provided a refined genome annotation and also new insights on the transcriptional structures and coding potential of this fish pathogen.How to cite: Millar AD, Tapia P, Gomez FA, et al.

  17. Choice of reference measurements affects quantification of long diffusion time behaviour using stimulated echoes.

    To demonstrate how reference data affect the quantification of the apparent diffusion coefficient (ADC) in long diffusion time measurements with diffusion-weighted stimulated echo acquisition mode (DW-STEAM) measurements, and to present a modification to avoid contribution from crusher gradients in DW-STEAM. For DW-STEAM, reference measurements at long diffusion times have significant b 0 value, because b = 0 cannot be achieved in practice as a result of the need for signal spoiling. Two strategies for acquiring reference data over a range of diffusion times were considered: constant diffusion weighting (fixed-b 0 ) and constant gradient area (fixed-q 0 ). Fixed-b 0 and fixed-q 0 were compared using signal calculations for systems with one and two diffusion coefficients, and experimentally using data from postmortem human corpus callosum samples. Calculations of biexponential diffusion decay show that the ADC is underestimated for reference images with b > 0, which can induce an apparent time-dependence for fixed-q 0 . Restricted systems were also found to be affected. Experimentally, the exaggeration of the diffusion time-dependent effect under fixed-q 0 versus fixed-b 0 was in a range predicted theoretically, accounting for 62% (longitudinal) and 35% (radial) of the time dependence observed in white matter. Variation in the b-value of reference measurements in DW-STEAM can induce artificial diffusion time dependence in ADC, even in the absence of restriction.

    2018-01-01

    Full Text Available Smartphone usage has been continuously increasing in recent years. In addition, Android devices are widely used in our daily life, becoming the most attractive target for hackers. Therefore, malware analysis of Android platform is in urgent demand. Static analysis and dynamic analysis methods are two classical approaches. However, they also have some drawbacks. Motivated by this, we present Demadroid, a framework to implement the detection of Android malware. We obtain the dynamic information to build Object Reference Graph and propose λ-VF2 algorithm for graph matching. Extensive experiments show that Demadroid can efficiently identify the malicious features of malware. Furthermore, the system can effectively resist obfuscated attacks and the variants of known malware to meet the demand for actual use.

  19. Clicks versus Citations: Click Count as a Metric in High Energy Physics Publishing

    Energy Technology Data Exchange (ETDEWEB)

    Bitton, Ayelet; /UC, San Diego /SLAC

    2011-06-22

    High-energy physicists worldwide rely on online resources such as SPIRES and arXiv to perform gather research and share their own publications. SPIRES is a tool designed to search the literature within high-energy physics, while arXiv provides the actual full-text documents of this literature. In high-energy physics, papers are often ranked according to the number of citations they acquire - meaning the number of times a later paper references the original. This paper investigates the correlation between the number of times a paper is clicked in order to be downloaded and the number of citations it receives following the click. It explores how physicists truly read what they cite.

    Full Text Available Using the InCites tool of Thomson Reuters, this study compares normalized citation impact values calculated for China, Japan, France, Germany, United States, and the UK throughout the time period from 1981 to 2010. InCites offers a unique opportunity to study the normalized citation impacts of countries using (i a long publication window (1981 to 2010, (ii a differentiation in (broad or more narrow subject areas, and (iii allowing for the use of statistical procedures in order to obtain an insightful investigation of national citation trends across the years. Using four broad categories, our results show significantly increasing trends in citation impact values for France, the UK, and especially Germany across the last thirty years in all areas. The citation impact of papers from China is still at a relatively low level (mostly below the world average, but the country follows an increasing trend line. The USA exhibits a stable pattern of high citation impact values across the years. With small impact differences between the publication years, the US trend is increasing in engineering and technology but decreasing in medical and health sciences as well as in agricultural sciences. Similar to the USA, Japan follows increasing as well as decreasing trends in different subject areas, but the variability across the years is small. In most of the years, papers from Japan perform below or approximately at the world average in each subject area.

  2. Report of the reference designs study group on the superconducting super collider

    International Nuclear Information System (INIS)

    1984-01-01

    In December, 1983, the directors of the US high energy accelerator laboratories chartered the National SSC Reference Designs Study to review in detail the technical and economic feasibility of various options for creating the Superconducting Super Collider (SSC) facility, a 20 TeV on 20 TeV proton-proton collider having a luminosity up to 10 33 cm -2 sec -1 . The primary objective of the study was to help the DOE, the high energy physics community, and the scientific community as a whole to decide how best to proceed with SSC R and D directed toward improving the cost effectiveness of applicable accelerator technology. We have concluded that the basic principles of design used successfully for existing accelerators can be conservatively extended to a proton collider having the SSC primary specifications of energy and luminosity. Furthermore, each of the three reference magnet styles studied could serve as the foundation for an SSC facility meeting these specifications. A vigorous R and D program of approximately three years duration will be required to refine the cost estimates for the magnets, to determine their actual performance, to determine their manufacturability and reliability, and to develop cost-effective methods for their assembly and quality assurance. It is anticipated that the magnet options can be narrowed to a single one during an early phase of the R and D program. An important R and D goal will be to produce, using mass-production methods, a significant number of magnets of the chosen style. These magnets would then be thoroughly tested under conditions simulating actual accelerator operations

    Purpose : Authors tried to enhance the safety and accuracy of radiosurgery by verifying stereotactic target point in actual treatment position prior to irradiation. Materials and Methods : Before the actual treatment, several sections of anthropomorphic head phantom were used to create a condition of unknown coordinated of the target point. A film was sand witched between the phantom sections and punctured by sharp needle tip. The tip of the needle represented the target point. The head phantom was fixed to the stereotactic ring and CT scan was done with CT localizer attached to the ring. After the CT scanning, the stereotactic coordinates of the target point were determined. The head phantom was secured to accelerator's treatment couch and the movement of laser isocenter to the stereotactic coordinates determined by CT scanning was performed using target positioner. Accelerator's anteroposterior and lateral portal films were taken using angiographic localizers. The stereotactic coordinates determined by analysis of portal films were compared with the stereotactic coordinates previously determined by CT scanning. Following the correction of discrepancy, the head phantom was irradiated using a stereotactic technique of several arcs. After the irradiation, the film which was sand witched between the phantom sections was developed and the degree of coincidence between the center of the radiation distribution with the target point represented by the hole in the film was measured. In the treatment of actual patients, the way of determining the stereotactic coordinates with CT localizers and angiographic localizers between two sets of coordinates, we proceeded to the irradiation of the actual patient. Results : In the phantom study, the agreement between the center of the radiation distribution and the localized target point was very good. By measuring optical density profiles of the sand witched film along axes that intersected the target point, authors could confirm

  6. Optimizing personalized normative feedback: the use of gender-specific referents.

    2007-03-01

    Many brief interventions include personalized normative feedback (PNF) using gender-specific or gender-neutral referents. Several theories suggest that information pertaining to more socially proximal referents should have greater influence on one's behavior compared with more socially distal referents. The current research evaluated whether gender specificity of the normative referent employed in PNF related to intervention efficacy. Following baseline assessment, 185 college students (45.2% women) were randomly assigned to one of three intervention conditions: gender-specific feedback, gender-neutral feedback, or assessment-only control. Immediately after completing measures of perceived norms, alcohol consumption, and gender identity, participants in the gender-neutral and gender-specific intervention conditions were provided with computerized information detailing their own drinking behavior, their perceptions of student drinking, and actual student drinking. After a 1-month follow-up, the results indicated that normative feedback was effective in changing perceived norms and reducing alcohol consumption for both intervention groups for women and men. The results provide support, however, for changes in perceived gender-specific norms as a mediator of the effects of normative feedback on reduced drinking behavior for women only. Additionally, gender-specific feedback was found to be more effective for women higher in gender identity, relative to the gender-neutral feedback. A post-assessment follow-up telephone survey administered to assess potential demand characteristics corroborated the intervention effects. Results extend previous research documenting efficacy of computer delivered PNF. Gender specificity and gender identity appear to be important elements to consider for PNF intervention efficacy for women.

    In recent years, many infrastructures have been deteriorating. In order to maintain sustainability of those infrastructures which have significant influence on social lifelines, economical and rational maintenance management should be carried out to evaluate the life cycle cost (LCC). The development of structural health monitoring systems, such as deriving evaluation techniques for the field structural condition of existing structures and identification techniques for the significant engineering properties of new structures, can be considered as the first step in resolving the above problem. New innovative evaluation methods need to be devised to identify the deterioration of infrastructures, e.g. steel tendons, cables in cable-stayed bridges and strands embedded in pre- or post-tensioned concrete structures. One of the possible solutions that show 'AtoE' characteristics, i.e., (a)ccuracy, (b)enefit, (c)ompendiousness, (d)urability and (e)ase of operation, elasto-magnetic (EM) actual stress sensory technology utilizing the sensitivity of incremental magnetic permeability to stress change, has been developed. Numerous verification tests on various steel materials have been conducted. By comparing with load cell, strain gage and other sensory technology measurement results, the actual stresses of steel tendons in a pre-stressed concrete structure at the following stages have been thoroughly investigated: (i) pre-stress change due to set-loss (anchorage slippage) at the tendon fixation stage; (ii) pre-stress change due to the tendon relaxation stage; (iii) concrete creep and shrinkage at the long term pre-stressing stage; (iv) pre-stress change in the cyclic fatigue loading stage; and (v) pre-stress change due to the re-pre-stress setting stage. As the result of this testing, it is confirmed that EM sensory technology enables one to measure actual stress in steel wire, strands and steel bars precisely without destroying the polyethylene covering sheath and enables

    Pair formation, acquiring a mate to form a reproductive unit, is a complex process. Mating preferences are a step in this process. However, due to constraining factors such as availability of mates, rival competition, and mutual mate choice, preferred characteristics may not be realised in the actual partner. People value height in their partner and we investigated to what extent preferences for height are realised in actual couples. We used data from the Millennium Cohort Study (UK) and compared the distribution of height difference in actual couples to simulations of random mating to test how established mate preferences map on to actual mating patterns. In line with mate preferences, we found evidence for: (i) assortative mating (r = .18), (ii) the male-taller norm, and, for the first time, (iii) for the male-not-too-tall norm. Couples where the male partner was shorter, or over 25 cm taller than the female partner, occurred at lower frequency in actual couples than expected by chance, but the magnitude of these effects was modest. We also investigated another preference rule, namely that short women (and tall men) prefer large height differences with their partner, whereas tall women (and short men) prefer small height differences. These patterns were also observed in our population, although the strengths of these associations were weaker than previously reported strength of preferences. We conclude that while preferences for partner height generally translate into actual pairing, they do so only modestly.

    2015-01-01

    We compared imagined versus actual affective and behavioral responses to witnessing a homophobic slur. Participants (N = 72) witnessed a confederate using a homophobic slur, imagined the same scenario, or were not exposed to the slur. Those who imagined hearing the slur reported significantly higher levels of negative affect than those who actually witnessed the slur, and nearly one half of them reported that they would confront the slur, whereas no participants who actually heard the slur confronted it. These findings reveal a discrepancy between imagined and real responses to homophobic remarks, and they have implications for the likelihood that heterosexuals will actually confront homophobic remarks.

    The island of Madagascar is a key hot spot for the genus Euphorbia, with at least 170 native species, almost all endemic. Threatened by habitat loss and illegal collection of wild plants, nearly all Malagasy Euphorbia are listed in CITES Appendices I and II. The absence of a reliable taxonomic revision makes it particularly difficult to identify these plants, even when fertile, and thereby compromises the application of CITES regulations. DNA barcoding, which can facilitate species-level identification irrespective of developmental stage and the presence of flowers or fruits, may be a promising tool for monitoring and controlling trade involving threatened species. In this study, we test the potential value of barcoding on 41 Euphorbia species representative of the genus in Madagascar, using the two widely adopted core barcode markers (matK and rbcL), along with two additional DNA regions, nuclear internal transcribed spacer (ITS) and the chloroplastic intergenic spacer psbA-trnH. For each marker and for selected marker combinations, inter- and intraspecific distance estimates and species discrimination rates are calculated. Results using just the 'official' barcoding markers yield overlapping inter- and intraspecific ranges and species discrimination rates below 60%. When ITS is used, whether alone or in combination with the core markers, species discrimination increases to nearly 100%, whereas the addition of psbA-trnH produces less satisfactory results. This study, the first ever to test barcoding on the large, commercially important genus Euphorbia shows that this method could be developed into a powerful identification tool and thereby contribute to more effective application of CITES regulations. © 2012 Blackwell Publishing Ltd.

    The purpose of this study was to investigate the difference between the radiographic gutta-percha terminus and the actual gutta-percha terminus of human molars by comparing radiographic obturation results with actual obturation results. Forty maxillary palatal roots and 50 mandibular distal roots were randomly selected from a population of 540. They were then mounted in stone and radiographed. Conventional endodontic therapy was completed using stainless-steel K files and lateral condensation. Each radiographic gutta-percha terminus was evaluated under 4.5x magnification by three examiners following the completion of root canal therapy. These results were recorded. Each tooth was then removed from its mounting, and the actual gutta-percha terminus was evaluated under 4.5x magnification. These results were recorded and compared to the radiographic gutta-percha terminus results. In all 90 teeth examined, the actual gutta-percha terminus was equal to or longer than the radiographic gutta-percha terminus. In the 50 mandibular distal roots, the actual gutta-percha terminus averaged 0.645 mm longer than the radiographic gutta-percha terminus. In the 40 maxillary palatal roots, this difference measured 0.6375 mm.

  14. Exaggerating Accessible Differences: When Gender Stereotypes Overestimate Actual Group Differences.

    Science.gov (United States)

    Eyal, Tal; Epley, Nicholas

    2017-09-01

    Stereotypes are often presumed to exaggerate group differences, but empirical evidence is mixed. We suggest exaggeration is moderated by the accessibility of specific stereotype content. In particular, because the most accessible stereotype contents are attributes perceived to differ between groups, those attributes are most likely to exaggerate actual group differences due to regression to the mean. We tested this hypothesis using a highly accessible gender stereotype: that women are more socially sensitive than men. We confirmed that the most accessible stereotype content involves attributes perceived to differ between groups (pretest), and that these stereotypes contain some accuracy but significantly exaggerate actual gender differences (Experiment 1). We observe less exaggeration when judging less accessible stereotype content (Experiment 2), or when judging individual men and women (Experiment 3). Considering the accessibility of specific stereotype content may explain when stereotypes exaggerate actual group differences and when they do not.

    PP and L has been monitoring temperatures in the Susquehanna SES reactor building with digital temperature recorders since 1986. In early 1990, data from four representative areas was analyzed to determine the temperature in each area which would produce the same rate of degradation as the distribution of actual temperatures recorded over about 40 months. From these effective average temperatures, qualified life multipliers were determined for activation energies in the range of 0.5 to 1.5 and those multipliers were used to estimate new qualified lives and the number of replacements which might be saved during the life of the plant. The results indicate that pursuing a program of determining EQ qualified lives from actual temperatures, rather than maximum design basis temperatures, will provide a substantial payback in reduced EQ driven maintenance

    A number of highway controlled shipments of radioactive materials have been made over the past several years. An excellent example showing the variability of actual routes is the transfer of 45 shipments between the Three Mile Island reactor in Pennsylvania and Scoville, Idaho in 1982 and 1983. Six different routes varying between 2273 and 2483 miles were used. Approximately 75% of these shipments followed a common route which passed through ten Urbanized Areas, defined by the Census Bureau as having a population exceeding 100,000 people. Other routes, while shorter in distance, passed through as many as 14 Urbanized Areas. Routes predicted by the Oak Ridge routing model did not exactly duplicate actual routes used. However, the analysis shows that the routing model does make a good estimate of transportation routes actually chosen by shippers of radioactive materials. In actual practice, a number of factors (weather, road conditions, driver preference, etc.) influence the actual route taken. 5 refs., 1 fig., 1 tab

    Full Text Available This study aimed at analyzing Iranian EFL teachers’ beliefs toward classroom management and the relationship between teachers’ beliefs and their actual practices of classroom management in regard with individual variables such as gender, education degree, and teaching experience. The data were collected using a behavior and instructional management scale inventory and direct class observation through a researcher made classroom management observation checklist. The findings showed that EFL teachers favored interactionalist orientation on behavior and instructional management dimensions. Findings also indicated that male teachers were not significantly different from females in terms of the relationship between their beliefs and actual practices. However, there was a significant relationship between teachers’ beliefs and their actual practices of classroom management among less experienced teachers. It was further found that increase in teachers’ educational level led to decrease in discrepancy between their beliefs and actual practices.

    Reference genes, often referred to as housekeeping genes (HKGs), are frequently used to normalize gene expression data based on the assumption that they are expressed at a constant level in the cells. However, several studies have shown that there may be a large variability in the gene expression levels of HKGs in various cell types. In a previous study, employing human embryonic stem cells (hESCs) subjected to spontaneous differentiation, we observed that the expression of commonly used HKG varied to a degree that rendered them inappropriate to use as reference genes under those experimental settings. Here we present a substantially extended study of the HKG signature in human pluripotent stem cells (hPSC), including nine global gene expression datasets from both hESC and human induced pluripotent stem cells, obtained during directed differentiation toward endoderm-, mesoderm-, and ectoderm derivatives. Sets of stably expressed genes were compiled, and a handful of genes (e.g., EID2, ZNF324B, CAPN10, and RABEP2) were identified as generally applicable reference genes in hPSCs across all cell lines and experimental conditions. The stability in gene expression profiles was confirmed by reverse transcription quantitative PCR analysis. Taken together, the current results suggest that differentiating hPSCs have a distinct HKG signature, which in some aspects is different from somatic cell types, and underscore the necessity to validate the stability of reference genes under the actual experimental setup used. In addition, the novel putative HKGs identified in this study can preferentially be used for normalization of gene expression data obtained from differentiating hPSCs.

    Full Text Available Remote sensing can assist in improving the estimation of the geographical distribution of evapotranspiration, and consequently water demand in large cultivated areas for irrigation purposes and sustainable water resources management. In the direction of these objectives, the daily actual evapotranspiration was calculated in this study during the summer season of 2001 over the Thessaly plain in Greece, a wide irrigated area of great agricultural importance. Three different methods were adapted and applied: the remotesensing methods by Granger (2000 and Carlson and Buffum (1989 that use satellite data in conjunction with ground meteorological measurements and an adapted FAO (Food and Agriculture Organisation Penman-Monteith method (Allen at al. 1998, which was selected to be the reference method. The satellite data were used in conjunction with ground data collected on the three closest meteorological stations. All three methods, exploit visible channels 1 and 2 and infrared channels 4 and 5 of NOAA-AVHRR (National Oceanic and Atmospheric Administration - Advanced Very High Resolution Radiometer sensor images to calculate albedo and NDVI (Normalised Difference Vegetation Index, as well as surface temperatures. The FAO Penman-Monteith and the Granger method have used exclusively NOAA-15 satellite images to obtain mean surface temperatures. For the Carlson-Buffum method a combination of NOAA-14 and ΝΟΑΑ-15 satellite images was used, since the average rate of surface temperature rise during the morning was required. The resulting estimations show that both the Carlson-Buffum and Granger methods follow in general the variations of the reference FAO Penman-Monteith method. Both methods have potential for estimating the spatial distribution of evapotranspiration, whereby the degree of the relative agreement with the reference FAO Penman-Monteith method depends on the crop growth stage. In particular, the Carlson- Buffum

    Recently, an applicability of wavelet transform for estimation of moderator temperature coefficient was shown in numerical simulations. The basic concept of the wavelet transform is to eliminate noise in the measured signals. The concept is similar to that of Fourier transform method in which the analyzed reactivity component is divided by the analyzed component of relevant parameter. In order to apply the method to analyze measured data in actual PWRs, we carried out numerical simulations on the data that were more similar to actual data and proposed a method for estimation of moderator temperature coefficient using the wavelet transform. In the numerical simulations we obtained moderator temperature coefficients with the relative error of less than 4%. Based on this result we applied this method to analyze measured data in actual PWRs and the results have proved that the method is applicable for estimation of moderator temperature coefficients in the actual PWRs. It is expected that this method can reduce the required data length during the measurement. We expect to expand the applicability of this method to estimate the other reactivity coefficients with the data of short transient. (author)

    2013-09-01

    Type T thermocouples are commonly used in industrial measurement applications due to their accuracy relative to other thermocouple types, low cost, and the ready availability of measurement equipment. Type T thermocouples are very effective when used in differential measurements, as there is no cold junction compensation necessary for the connections to the measurement equipment. Type T's published accuracy specifications result in its frequent use in low temperature applications. An examination of over 328 samples from a number of manufacturers has been completed for this investigation. Samples were compared to a Standard Platinum Resistance Thermometer (SPRT) at the LN2 boiling point along with four other standardized measurement points using a characterized ice point reference, low-thermal EMF scanner and an 8.5 digit multimeter, and the data compiled and analyzed. The test points were approximately -196 °C, -75 °C, 0 °C, +100 °C, and +200 °C. These data show an anomaly in the conformance to the reference functions where the reference functions meet at 0 °C. Additionally, in the temperature region between -100 °C to -200 °C, a positive offset of up to 5.4 °C exists between the reference function equations published in the ASTM E230-06 for the nitrogen point and the measured response of the actual wire. This paper will examine the historical and technological reasons for this anomaly in the both the ASTM and IEC reference functions. At the request of the author and the Proceedings Editor the above article has been replaced with a corrected version. The original PDF file supplied to AIP Publishing contained several figures with missing information/characters—caused by processes used to generate the PDF file.

    Perception of peer behaviors is an important predictor of actual risk behaviors among youth. However, we lack understanding of peer influence through social media and of actual and perceived peer behavior concordance. The purpose of this research is to document the relationship between individual perception of and actual peer sexual risk behavior using online social networks. The data are a result of a secondary analysis of baseline self-reported and peer-reported sexual risk behavior from a cluster randomized trial including 1,029 persons from 162 virtual networks. Individuals (seeds) recruited up to three friends who then recruited additional friends, extending three waves from the seed. ANOVA models compared network means of actual participant behavior across categories of perceived behavior. Concordance varied between reported and perceived behavior, with higher concordance between perceived and reported condom use, multiple partners, concurrent partners, sexual pressure, and drug and alcohol use during sex. Individuals significantly over-reported risk and under-reported protective peer behaviors related to sex.

    The reference system classification represents a basic stage in the organization of the European reliability data system (ERDS) for light-water reactors, a project actually in development at the Joint Research Centre, Ispra. This project is concerned with operational reliability data collection from the various ''national'' data banks, and centralization in a European reliability data system, so improving the significance of the resulting reliability evaluations. In the framework of the ERDS project, the reference system classification provides a LWR functional break-down and represents a plant-unique identification in the process of homogenization of event-data coming from the various ''national'' organizations. The report, after a brief description of the main objectives of the ERDS project, reviews the criteria followed in the elaboration of the reference system classification; then the detailed classification is presented. The nuclear power station is subdivided in about 180 systems. To each system a sheet is associated, containing: a comprehensive description of system-functions and boundaries; a descritpion of the plant operating mode, linked to the various system functions; a list of the main interface system; and finally, a list of the main components, including type and safety classification

    As a critical component of the energy and water cycle, terrestrial actual evapotranspiration (ET) can be influenced by many factors. This study was mainly devoted to providing accurate and continuous estimations of actual ET for the Tibetan Plateau (TP) and analyzing the effects of its impact factors. In this study, summer observational data from the Coordinated Enhanced Observing Period (CEOP) Asia-Australia Monsoon Project (CAMP) on the Tibetan Plateau (CAMP/Tibet) for 2003 to 2004 was selected to determine actual ET and investigate its relationship with energy, hydrological, and dynamical parameters. Multiple-layer air temperature, relative humidity, net radiation flux, wind speed, precipitation, and soil moisture were used to estimate actual ET. The regression model simulation results were validated with independent data retrieved using the combinatory method. The results suggested that significant correlations exist between actual ET and hydro-meteorological parameters in the surface layer of the Nagqu river basin, among which the most important factors are energy-related elements (net radiation flux and air temperature). The results also suggested that how ET is eventually affected by precipitation and two-layer wind speed difference depends on whether their positive or negative feedback processes have a more important role. The multivariate linear regression method provided reliable estimations of actual ET; thus, 6-parameter simplified schemes and 14-parameter regular schemes were established.

    The National Oceanic and Atmospheric Administration (NOAA) provides daily reference evapotranspiration (ETref) maps for the contiguous United States using climatic data from North American Land Data Assimilation System (NLDAS). This data provides large-scale spatial representation of ETref, which is essential for regional scale water resources management. Data used in the development of NOAA daily ETref maps are derived from observations over surfaces that are different from short (grass — ETos) or tall (alfalfa — ETrs) reference crops, often in nonagricultural settings, which carries an unknown discrepancy between assumed and actual conditions. In this study, NOAA daily ETos and ETrs maps were evaluated for accuracy, using observed data from the Texas High Plains Evapotranspiration (TXHPET) network. Daily ETos, ETrs and the climatic data (air temperature, wind speed, and solar radiation) used for calculating ETref were extracted from the NOAA maps for TXHPET locations and compared against ground measurements on reference grass surfaces. NOAA ETrefmaps generally overestimated the TXHPET observations (1.4 and 2.2 mm/day ETos and ETrs, respectively), which may be attributed to errors in the NLDAS modeled air temperature and wind speed, to which reference ETref is most sensitive. Therefore, a bias correction to NLDAS modeled air temperature and wind speed data, or adjustment to the resulting NOAA ETref, may be needed to improve the accuracy of NOAA ETref maps.

  9. Reference-free ground truth metric for metal artifact evaluation in CT images

    2011-01-01

    Purpose: In computed tomography (CT), metal objects in the region of interest introduce data inconsistencies during acquisition. Reconstructing these data results in an image with star shaped artifacts induced by the metal inconsistencies. To enhance image quality, the influence of the metal objects can be reduced by different metal artifact reduction (MAR) strategies. For an adequate evaluation of new MAR approaches a ground truth reference data set is needed. In technical evaluations, where phantoms can be measured with and without metal inserts, ground truth data can easily be obtained by a second reference data acquisition. Obviously, this is not possible for clinical data. Here, an alternative evaluation method is presented without the need of an additionally acquired reference data set. Methods: The proposed metric is based on an inherent ground truth for metal artifacts as well as MAR methods comparison, where no reference information in terms of a second acquisition is needed. The method is based on the forward projection of a reconstructed image, which is compared to the actually measured projection data. Results: The new evaluation technique is performed on phantom and on clinical CT data with and without MAR. The metric results are then compared with methods using a reference data set as well as an expert-based classification. It is shown that the new approach is an adequate quantification technique for artifact strength in reconstructed metal or MAR CT images. Conclusions: The presented method works solely on the original projection data itself, which yields some advantages compared to distance measures in image domain using two data sets. Beside this, no parameters have to be manually chosen. The new metric is a useful evaluation alternative when no reference data are available.

    Tenure security plays an important role in farm households' investment, land renting and other decisions. Recent literature distinguishes between actual farmland tenure security (i.e. farm households' actual control of farmland) and perceived farmland tenure security (i.e. farm households' subjective understanding of their farmland tenure situation and expectation regarding government enforcement and equality of the law). However little is known on what factors influence the actual and perceived farmland tenure security in rural China. Theoretically, actual farmland tenure security is related to village self-governance as a major informal governance rule in rural China. Both economic efficiency and equity considerations are likely to play a role in the distribution of land and its tenure security. Household perceptions of farmland tenure security depend not only on the actual farmland tenure security in a village, but may also be affected by households' investment in and ability of changing social rules. Our study examines what factors contribute to differences in actual and perceived farmland tenure security between different villages and farm households in different regions of China. Applying probit models to the data collected from 1,485 households in 124 villages in Jiangsu, Jiangxi, Liaoning and Chongqing, we find that development of farmland rental market and degree of self-governance of a village have positive impacts, and development of labour market has a negative effect on actual farmland tenure security. Household perceptions of tenure security depend not only on actual farmland tenure security and on households' investment in and ability of changing social rules, but also on risk preferences of households. This finding has interesting policy implications for future land reforms in rural China.

En primer lugar, se describe la comunidad de usuarios a nivel global, focalizando en el uso actual que el software ha alcanzado en Argentina: la cantidad de implementaciones disponibles, su evolución, el tipo, tamaño y variedad de los desarrollos existentes, así como su aplicación a la gestión de repositorios digitales de ciencia y tecnología en el ámbito de las instituciones científicas, tecnológicas y de educación superior en Argentina. En segundo lugar, se detallan las acciones llevadas a cabo a partir de la creación del Centro Nacional de Promoción de Greenstone en Argentina en 2009. Datos recabados en encuestas realizadas permitieron observar que las razones predominantes para elegir esta plataforma fueron, entre otras, su facilidad de instalación y configuración, su bajo nivel de requerimiento tecnológico, la generalizada escasez de recursos humanos dedicados a esta actividad, y la complejidad que presentaban los softwares alternativos existentes en ese momento. A lo largo de estos 8 años, tanto los repositorios digitales como los sistemas que los soportan evolucionaron drásticamente, modificando el escenario actual. Paralelamente, en 2016 la nueva versión mayor de Greenstone implementó una reingeniería completa del software para su adaptación a las tecnologías en uso: XML, XSLT, Web-services y Java. Como consecuencia de esto, la comunidad de desarrollo local se plantea nuevos desafíos para la migración de las bibliotecas digitales y repositorios implementados con versiones anteriores.

    The Appalachian basin contains abundant coal and petroleum resources that have been studied and extracted for at least 150 years. In this volume, U.S. Geological Survey (USGS) scientists describe the geologic framework and geochemical character of the fossil-fuel resources of the central and southern Appalachian basin. Separate subchapters (some previously published) contain geologic cross sections; seismic profiles; burial history models; assessments of Carboniferous coalbed methane and Devonian shale gas; distribution information for oil, gas, and coal fields; data on the geochemistry of natural gas and oil; and the fossil-fuel production history of the basin. Although each chapter and subchapter includes references cited, many historical or other important references on Appalachian basin and global fossil-fuel science were omitted because they were not directly applicable to the chapters.

    2010-01-01

    The flexible structure of photonic crystal fibre not only offers novel optical properties but also brings some difficulties in keeping the fibre structure in the fabrication process which inevitably cause the optical properties of the resulting fibre to deviate from the designed properties. Therefore, a method of evaluating the optical properties of the actual fibre is necessary for the purpose of application. Up to now, the methods employed to measure the properties of the actual photonic crystal fibre often require long fibre samples or complex expensive equipments. To our knowledge, there are few studies of modeling an actual photonic crystal fibre and evaluating its properties rapidly. In this paper, a novel method, based on the combination model of digital image processing and the finite element method, is proposed to rapidly model the optical properties of the actual photonic crystal fibre. Two kinds of photonic crystal fibres made by Crystal Fiber A/S are modeled. It is confirmed from numerical results that the proposed method is simple, rapid and accurate for evaluating the optical properties of the actual photonic crystal fibre without requiring complex equipment.

    Full Text Available This paper aims at to present the essence and the role of economic education related to the natural movement of a functioning market economy in the Romanian actuality. We understand education as an important form of social consciousness in the sense of bipolarity, namely as the premise and the effect at a dynamic microeconomic and macroeconomic level. In this dynamic movement, economic education appears more and more visibly as a new factor of production or as a new dimension of human capital. In our approach we consider several theoretical and methodological axes that allow us to reveal the interdependence of education to the economic and social development, from an emulative or frantic perspective. In this way we treat the evolution of complex phenomena of economic education in terms of public policy, highlighting the need to intensify the decision-making efforts of management and execution, consistent pursuing to link the causes with the effects of economic education in the Romanian actuality.

    Objective To identify the top-cited articles in gastroenterology and hepatology, and analyse their characteristics. Methods Two searches were conducted in the Science Citation Index Expanded database; a search of 69 journals under the category ‘Gastroenterology and Hepatology’ (list A) and a keyword search of all journals (list B). The search results were analysed and the inter-rater coefficient of agreement between evaluators was measured using Cohen κ. Results The number of citations varied from 1049 to 2959 in list A and from 1929 to 5500 in list B. In both lists, the majority of articles were research papers. No significant correlations were found between the number of citations and the number of years since publication (R2=0.00992, p=0.473 and R2=0.00202, p=0.757, respectively). However, the mean number of citations of papers published before the year 2000 was lower than those published after 2000 (36.70±19.31 vs 106.03±39.22). No correlation was found between number of authors and the number of citations (R2=0.04352, p=0.130), but strong correlations were found between the number of institutes involved or number of countries and the number of citations (R2=0.275, particles were not only published in highly ranked journals specialising in Gastroenterology and Hepatology but also in 14 journals not specialised in this field. The number of citations correlated with the number of institutes and the number of countries involved but not with the number of grants received or the number of authors. Females were under-represented in the authorship. PMID:26857105

    Medical students have to process a large amount of information during the first years of their study, which has to be retained over long periods of nonuse. Therefore, it would be beneficial when knowledge is gained in a way that promotes long-term retention. Paper-and-pencil drawings for the uptake of form-function relationships of basic tissues has been a teaching tool for a long time, but now seems to be redundant with virtual microscopy on computer-screens and printers everywhere. Several studies claimed that, apart from learning from pictures, actual drawing of images significantly improved knowledge retention. However, these studies applied only immediate post-tests. We investigated the effects of actual drawing of histological images, using randomized cross-over design and different retention periods. The first part of the study concerned esophageal and tracheal epithelium, with 384 medical and biomedical sciences students randomly assigned to either the drawing or the nondrawing group. For the second part of the study, concerning heart muscle cells, students from the previous drawing group were now assigned to the nondrawing group and vice versa. One, four, and six weeks after the experimental intervention, the students were given a free recall test and a questionnaire or drawing exercise, to determine the amount of knowledge retention. The data from this study showed that knowledge retention was significantly improved in the drawing groups compared with the nondrawing groups, even after four or six weeks. This suggests that actual drawing of histological images can be used as a tool to improve long-term knowledge retention. © 2015 American Association of Anatomists.

    The need for transplants continues to exceed organ and tissue donor availability. Although recent surgical advances have resulted in successful transplants using very small pediatric donors, including neonates, the actual practice of neonatal organ donation after circulatory determination of death (DCDD) remains uncommon. To describe the percentage of neonates potentially eligible for DCDD, including those who underwent successful donation, and reasons for ineligibility in those who did not in a single neonatal intensive care unit (NICU). We obtained data from the Children's Hospital Neonatal Database and Intermountain Donor Services (IDS) organ procurement records. The 136 deaths that occurred in the NICU of the Primary Children's Hospital, Salt Lake City, Utah, from January 1, 2010, through May 7, 2013, were reviewed retrospectively from January 12 through July 1, 2014, to determine potential eligibility for DCDD as determined by IDS minimum eligibility criteria (requirement of life-sustaining interventions and weight >2 kg). For patients who did not undergo DCDD, we reviewed records to determine the reasons for ineligibility. Potential eligibility for DCDD among neonates who died in the study NICU. Of 136 deaths in the NICU, 60 (44.1%) met criteria for DCDD; however, fewer than 10% were referred appropriately to the regional organ procurement organization for evaluation. Forty-five neonates (33.1%) ultimately died within 90 minutes of withdrawal of life-sustaining interventions and thus would have been eligible for organ donation based on warm ischemic time. The most common causes of death among the 60 potentially eligible neonatal donors were neonatal encephalopathy (n = 17) and multiple congenital anomalies (n = 14). Nonreferral or late referral by the medical team was the most frequent reason for donor ineligibility, including 49 neonates (36.0%). Overall, only 4 neonates (2.9%) underwent successful DCDD. Although almost half of all neonatal deaths

    It is important to estimate accurately a water balance in watershed for proposing a reuse of water resources and a proper settlement of water utilization. Evapotranspiration (ET) is an important factor of water balance. Therefore, it is needed to estimate accurately the actual ET. The objective of this study is to estimate accurately monthly actual ET in Yoshii, Asahi, and Takahashi River watersheds in Okayama prefecture from 1999 to 2000. The monthly actual ET was calculated by a Morton and a modified Brutsaert and Stricker (B&S) method, using Automated Meteorological Data Acquisition Systems (AMeDAS) in the basin. The actual ET was estimated using land covers which were classified in 11 categories. The land covers includes the effects of albedo. The actual ET was related to the elevation at each AMeDAS station. Using this relationship, the actual ET at the 1 or 5 km grid-interval mesh in the basin was calculated, and finally, the distribution of actual ET was mapped. The monthly ET estimated by the modified B&S method were smaller than that by Morton method which showed a same tendency as the Penman potential ET (PET). The annual values of Morton"fs ET, modified B&S"fs ET, and PET were estimated as 796, 645, and 800 mm, respectively. The ET by the modified B&S was larger in hilly and mountainous areas than in settlement or city. In general, it was a reasonable result because city or settlement areas were covered with concrete and asphalt and the ET was controlled.

For this study, we analyzed the current principle of managerial accounting to an entity in the studied area, in order to emphasize the need of organizing and implementing a modern accounting management to control the cost and increase the performance of the entities in this area, starting from the premise that there are sufficient similarities between entities in the field. The research has highlighted the fact that, nowadays, the cost calculation is organized using traditional methods, which focus on the monthly determination of the actual unit cost per product (semi-fabric and that it is necessary to organize and implement a managerial accounting, based on the use of a modern method, namely the standard cost method combined with cost centre method. The major implications of the proposed system for the researched field are the monthly calculation of actual costs per cost centres, the calculation of the actual cost per product, as the final cost carrier, to be performed over longer periods of time, usually, quarterly.

    2002-12-01

    Out of the concept of neurasthenia, the main non-psychotic diagnosis of nineteenth-century psychiatry besides hysteria, and on the basis of psychophysiological problems of his own, self-diagnosed as neurasthenia, Freud developed the notion of 'actual neurosis', a 'contentless psychic state' manifested by various somatic symptoms and a depressive mood, which he attributed to a chemical factor associated with aberrant sexual practices and in particular masturbation. Rejected by post-Freudian analysts as such along with the diagnosis of neurasthenia, the concept of 'actual neurosis' has survived under various theoretical schemes that seek to explain psychosomatic illness and somatisation, in general, with its concomitant poverty of affects and dearth of fantasy life. In more recent years, the concept of 'actual neurosis' has resurfaced under the label of chronic fatigue syndrome, a medical entity thought to be an immunological deficiency, while in psychoanalysis Freud's idea of a contentless mental state has been replaced by that of unconscious fantasy and symbolisation at a pre-genital or pre-verbal level.

    1991-01-01

    In support of a continuing program of systematic evaluation of nuclear structure data, the National Nuclear Data Center maintains a complete computer file of references to the nuclear physics literature. Each reference is tagged by a keyword string, which indicates the kinds of data contained in the article. This master file of Nuclear Structure References (NSR) contains complete keyword indexes to literature published since 1969, with partial indexing of older references. Any reader who finds errors in the keyword descriptions is urged to report them to the National Nuclear Data Center so that the master NSR file can be corrected. In 1966, the first collection of Recent References was published as a separate issue of Nuclear Data Sheets. Every four months since 1970, a similar indexed bibliography to new nuclear experiments has been prepared from additions to the NSR file and published. Beginning in 1978, Recent References was cumulated annually, with the third issue completely superseding the two issues previously published during a given year. Due to publication policy changes, cumulation of Recent Reference was discontinued in 1986. The volume and issue number of all the cumulative issues published to date are given. NNDC will continue to respond to individual requests for special bibliographies on nuclear physics topics, in addition to those easily obtained from Recent References. If the required information is available from the keyword string, a reference list can be prepared automatically from the computer files. This service can be provided on request, in exchange for the timely communication of new nuclear physics results (e.g., preprints). A current copy of the NSR file may also be obtained in a standard format on magnetic tape from NNDC. Requests for special searches of the NSR file may also be directed to the National Nuclear Data Center

  19. Report of the Reference Designs Study Group on the superconducting super collider

    International Nuclear Information System (INIS)

    1984-05-01

    The study was based on three different styles of superconducting magnets, each emphasizing a different configuration aimed at sharply decreasing the cost of producing the needed magnet system below that achievable with existing designs. In the study three key areas were addressed: technical feasibility; economic feasibility; and identification of specific R and D needs. Primary emphasis was on estimating the cost range within which SSC construction can confidently be expected to fall. In doing this, attention was focused on the cost of creating the collider itself. The costs of research equipment, preconstruction R and D, and possible site acquisition are not included in this study. The report of the Reference Designs Study is meant neither as a proposal for SSC construction, nor as a site preference statement. We have concluded that the basic principles of design used successfully for existing accelerators can be conservatively extended to a proton collider having the SSC primary specifications of energy and luminosity. Furthermore, each of the three reference magnet styles studied could serve as the foundation for an SSC facility meeting these specifications. A vigorous R and D program of approximately three years duration will be required to refine the cost estimates for the magnets, to determine their actual performance, to determine their manufacturability and reliability, and to develop cost-effective methods for their assembly and quality assurance. It is anticipted that the magnet options can be narrowed to a single one during an early phase of the R and D program. An important R and D goal will be to produce, using mass-production methods, a significant number of magnets of the chosen style. These magnets would then be thoroughly tested under conditions simulating actual accelerator operations

  2. Theoretical vs. actual energy consumption of labelled dwellings in the Netherlands: Discrepancies and policy implications

    2013-01-01

    In Europe, the Energy Performance of Buildings Directive (EPBD) provides for compulsory energy performance certification (labelling) for all existing dwellings. In the Netherlands, a labelling scheme was introduced in 2008. Certificates contain the energy label of the dwelling and corresponding theoretical gas and electricity consumption, calculated based on the dwellings physical characteristics, its heating, ventilation and cooling systems and standard use characteristics. This paper reports on a large-scale study of around 200,000 dwellings comparing labels and theoretical energy use with data on actual energy use. The study shows that dwellings with a low energy label actually consume much less energy than predicted by the label, but on the other hand, energy-efficient dwellings consume more than predicted. In practice, policy targets are set according to the theoretical rather than the actual consumptions of the building stock. In line with identified discrepancies, the study shows that whereas most energy reduction targets can be met according to the theoretical energy consumption of the dwelling stock, the future actual energy reduction potential is much lower and fails to meet most of the current energy reduction targets. - Highlights: ► Actual gas consumption in Dutch dwellings is lower than the theoretical. ► In the dwellings with label A–B, theoretical gas consumption is lower than actual gas consumption. ► In less efficient dwellings, theoretical gas consumption is much higher than the actual. ► Most current energy reduction targets are unachievable if modelled with actual instead of theoretical energy consumption

    With a mandatory labeling scheme for GM food in Europe since 2004 measuring actual consumer choice in practice has become possible. Anticipating Europeans negative attitude toward GM food, the labeling was enforced to allow consumers to make an informed choice. We studied consumers actual purchase behavior of GM food products and compared this with their attitude and behavioral intention for buying GM food. We found that despite a majority of consumers voicing a negative attitude toward GM food over 50% of our European respondents stated that they did not actively avoid the purchase of GM food and 6% actually purchased one of the few available GM labeled food products in the period between September 2006 and October 2007. Our results imply that a voiced negative attitude of consumers in responses to questionnaires about their intentions is not a reliable guide for what they actually do in supermarkets. We conclude that the assumption of a negative attitude with regard to GM food is at least in part construed.

  4. Actual and theoretical gas consumption in Dutch dwellings: What causes the differences?

    2013-01-01

    Energy labels in buildings are awarded based on theoretical gas and electricity consumption based on dwelling's physical characteristics. Prior to this research, a large-scale study was conducted in The Netherlands comparing theoretical energy use with data on actual energy use revealing substantial discrepancies (Majcen et al., 2013). This study uses identical energy label data, supplemented with additional data sources in order to reveal how different parameters influence theoretical and actual consumptions gas and electricity. Analysis is conducted through descriptive statistics and regression analysis. Regression analysis explained far less of the variation in the actual consumption than in the theoretical and has shown that variables such as floor area, ownership type, salary and the value of the house, which predicted a high degree of change in actual gas consumption, were insignificant (ownership, salary, value) or had a minor impact on theoretical consumption (floor area). Since some possibly fundamental variables were unavailable for regression analysis, we also conducted a sensitivity study of theoretical gas consumption. It showed that average indoor temperature, ventilation rate and accuracy of U-value have a large influence on the theoretical gas consumption; whereas the number of occupants and internal heat load have a rather limited impact. - Highlights: • Floor area, ownership, salary and value predict the change in actual gas use well. • Mentioned variables are insignificant or have small impact on theoretical use. • Energy consumption of less energy efficient systems is overestimated. • Accurate model assumptions and inspections would reduce the discrepancies. • Big discrepancies stem from misassumption of temperature, heated floor area, U values

    International trade of several Dalbergia wood species is regulated by The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). In order to supplement morphological identification of these species, a rapid chemical method of analysis was developed. Using Direct Analysis in Real Time (DART) ionization coupled with Time-of-Flight (TOF) Mass Spectrometry (MS), selected Dalbergia and common trade species were analyzed. Each of the 13 wood species was classified using principal component analysis and linear discriminant analysis (LDA). These statistical data clusters served as reliable anchors for species identification of unknowns. Analysis of 20 or more samples from the 13 species studied in this research indicates that the DART-TOFMS results are reproducible. Statistical analysis of the most abundant ions gave good classifications that were useful for identifying unknown wood samples. DART-TOFMS and LDA analysis of 13 species of selected timber samples and the statistical classification allowed for the correct assignment of unknown wood samples. This method is rapid and can be useful when anatomical identification is difficult but needed in order to support CITES enforcement. Published 2012. This article is a US Government work and is in the public domain in the USA.

    2017-01-01

    When raindrops impact on the surface of a piezoelectric beam, strain energy produced by the impinging raindrop will be converted to harvestable electrical energy by the piezoelectric layers in a cantilever beam. The novelty of this study is to investigate the performance of the harvester in actual rain and provide practical insights on implementation. The influences of rain parameters such as rain rate, rainfall depth, raindrop count, and drop size distribution (DSD) are discussed in this study. The raindrops accumulated on the surface of the piezoelectric beam will form a water layer. It is described using added mass coefficient in this study. In an actual rain experiment, a piezoelectric beam with surface area of 0.0018 m 2 is able to produce 2076 μJ of energy over a duration of 301 min. The energy generation of a raindrop impact piezoelectric energy harvester is highly dependent on the rain rate. Due to the inconsistency of the energy generation, the piezoelectric energy harvester would require an integration of suitable energy storage device for continuous operation. Nevertheless, this work shows the feasibility of harvesting raindrop energy using a piezoelectric beam. - Highlights: • The performance of a piezoelectric rain energy harvester is tested in actual rain. • The energy generation is highly dependent on the rain rate. • Practical insights on the implementation of the harvester are discussed. • A total energy of 2076 μJ is generated over a duration of 301 min.

    The relationship between actual and perceived object control competence (ball skills) and the contribution to young children's physical activity is not known. Cross sectional study. The Test Gross Motor Development-2 assessed actual object control competence and a modified version of the Pictorial Scale of Perceived Competence and Social Acceptance for Young Children assessed perceived object control competence. Moderate- to vigorous-intensity physical activity was measured via accelerometry. Three mixed regression models were performed: (i) object control competence as the predictor and the outcome as perceived object control, (ii) perceived object control competence as the predictor and the outcome moderate to vigorous physical activity and (iii) actual object control as the predictor and the outcome moderate to vigorous physical activity. Models adjusted for school clustering, monitor wear time, sex and age. Interactions between respective predictor variables and sex were performed if warranted. A total of 102 children (56% boys, 44% girls) aged 4-8 years (M 6.3, SD 0.92) completed assessments. Girls had lower perceived and actual object control competence and were less active than boys. Actual object control competence was positively associated with perceived object control competence (B=0.11, t(96)=2.25, pperceived object control competence (p=0.827) were associated with moderate to vigorous physical activity. Young children's perceived ball skill abilities appear to relate to actual competence; however, these measures were not associated with physical activity. In older children, object control skill is associated with physical activity so targeting young children's object control skills is an intervention priority. Crown Copyright © 2014.

    Full Text Available Introduction. This study investigated unmonitored referrals in a nationwide, collaborative chat reference service. Specifically, it examined the extent to which questions are referred, the types of questions that are more likely to be referred than others, and the level of user satisfaction with the referrals in the collaborative chat reference service. Method. The data analysed for this study were 420 chat reference transaction transcripts along with corresponding online survey questionnaires submitted by the service users. Both sets of data were collected from an electronic archive of a southeastern state public library system that has participated in 24/7 Reference of the Metropolitan Cooperative Library System (MCLS. Results. Referrals in the collaborative chat reference service comprised approximately 30% of the total transactions. Circulation-related questions were the most often referred among all question types, possibly because of the inability of 'outside' librarians to access patron accounts. Most importantly, user satisfaction with referrals was found to be significantly lower than that of completed answers. Conclusion. The findings of this study addressed the importance of distinguishing two types of referrals: the expert research referrals conducive to collaborative virtual reference services; and the re-directional local referrals that increase unnecessary question traffic, thereby being detrimental to effective use of collaborative reference. Continuing efforts to conceptualize referrals in multiple dimensions are anticipated to fully grasp complex phenomena underlying referrals.

  11. Effect of reference conditions on flow rate, modifier fraction and retention in supercritical fluid chromatography.

    When using compressible mobile phases such as fluidic CO2, the density, the volumetric flow rates and volumetric fractions are pressure dependent. The pressure and temperature definition of these volumetric parameters (referred to as the reference conditions) may alter between systems, manufacturers and operating conditions. A supercritical fluid chromatography system was modified to operate in two modes with different definition of the eluent delivery parameters, referred to as fixed and variable mode. For the variable mode, the volumetric parameters are defined with reference to the pump operating pressure and actual pump head temperature. These conditions may vary when, e.g. changing the column length, permeability, flow rate, etc. and are thus variable reference conditions. For the fixed mode, the reference conditions were set at 150bar and 30°C, resulting in a mass flow rate and mass fraction of modifier definition which is independent of the operation conditions. For the variable mode, the mass flow rate of carbon dioxide increases with system pump operating pressure, decreasing the fraction of modifier. Comparing the void times and retention factor shows that the deviation between the two modes is almost independent of modifier percentage, but depends on the operating pressure. Recalculating the set volumetric fraction of modifier to the mass fraction results in the same retention behaviour for both modes. This shows that retention in SFC can be best modelled using the mass fraction of modifier. The fixed mode also simplifies method scaling as it only requires matching average column pressure.

Two searches were conducted in the Science Citation Index Expanded database; a search of 69 journals under the category 'Gastroenterology and Hepatology' (list A) and a keyword search of all journals (list B). The search results were analysed and the inter-rater coefficient of agreement between evaluators was measured using Cohen κ. The number of citations varied from 1049 to 2959 in list A and from 1929 to 5500 in list B. In both lists, the majority of articles were research papers. No significant correlations were found between the number of citations and the number of years since publication (R(2)=0.00992, p=0.473 and R(2)=0.00202, p=0.757, respectively). However, the mean number of citations of papers published before the year 2000 was lower than those published after 2000 (36.70 ± 19.31 vs 106.03 ± 39.22). No correlation was found between number of authors and the number of citations (R(2)=0.04352, p=0.130), but strong correlations were found between the number of institutes involved or number of countries and the number of citations (R(2)=0.275, pGastroenterology and Hepatology but also in 14 journals not specialised in this field. The number of citations correlated with the number of institutes and the number of countries involved but not with the number of grants received or the number of authors.

    Job satisfaction is essential for physicians' well-being and patient care. The work ethic of long days and hard work that has been advocated for decades is acknowledged as a threat for physicians' job satisfaction, well-being, and patient safety. Our aim was to determine the actual and preferred job size of physicians and to investigate how these and the differences between them influence physicians' job satisfaction. Data were retrieved from a larger, longitudinal study among physicians starting medical training at Groningen University in 1982/83/92/93 (N = 597). Data from 506 participants (85%) were available for this study. We used regression analysis to investigate the influence of job size on physicians' job satisfaction (13 aspects) and ANOVA to examine differences in job satisfaction between physicians wishing to retain, reduce or increase job size. The majority of the respondents (57%) had an actual job size less than 1.0 FTE. More than 80% of all respondents preferred not to work full-time in the future. Respondents' average actual and preferred job sizes were .85 FTE and .81 FTE, respectively. On average, respondents who wished to work less (35% of respondents) preferred a job size reduction of 0.18 FTE and those who wished to work more (12%) preferred an increase in job size of 0.16 FTE. Job size influenced satisfaction with balance work-private hours most (β = -.351). Physicians who preferred larger job sizes were - compared to the other groups of physicians - least satisfied with professional accomplishments. A considerable group of physicians reported a gap between actual and preferred job size. Realizing physicians' preferences as to job size will hardly affect total workforce, but may greatly benefit individual physicians as well as their patients and society. Therefore, it seems time for a shift in work ethic.

    2012-10-01

    From citation rates for over 85,000 articles published between 1950 and 2004 in 56 psychology journals, we identified a total of 500 behavioral cognitive psychology articles that ranked in the top 0.6% in each half-decade, in terms of their mean citations per year using the Web of Science. Thirty nine percent [corrected] of these articles were produced by 78 authors who authored three or more of them, and more than half were published by only five journals.The mean number of cites per year and the total number of citations necessary for an article to achieve various percentile rankings are reported for each journal. The mean number of citations necessary for an article published within each half-decade to rank at any given percentile has steadily increased from 1950 to 2004. Of the articles that we surveyed, 11% had zero total citations, and 35% received fewer than four total citations. Citations for post-1994 articles ranking in the 50th-75th and 90th-95th percentiles have generally continued to grow across each of their 3-year postpublication bins. For pre-1995 articles ranking in the 50th-75th and 90th-95th percentiles, citations peaked in the 4- to 6- or 7- to 9-year postpublication bins and decreased linearly thereafter, until asymptoting. In contrast, for the top-500 articles, (a) for pre-1980 articles, citations grew and peaked 10-18-year postpublication bins, and after a slight decrease began to linearly increase again; (b) for post-1979 articles, citations have continually increased across years in a nearly linear fashion. We also report changes in topics covered by the top-cited articles over the decades.

    This study presents a reference-free fatigue crack detection technique using nonlinear ultrasonic modulation. When low frequency (LF) and high frequency (HF) inputs generated by two surface-mounted lead zirconate titanate (PZT) transducers are applied to a structure, the presence of a fatigue crack can provide a mechanism for nonlinear ultrasonic modulation and create spectral sidebands around the frequency of the HF signal. The crack-induced spectral sidebands are isolated using a combination of linear response subtraction (LRS), synchronous demodulation (SD) and continuous wavelet transform (CWT) filtering. Then, a sequential outlier analysis is performed on the extracted sidebands to identify the crack presence without referring any baseline data obtained from the intact condition of the structure. Finally, the robustness of the proposed technique is demonstrated using actual test data obtained from simple aluminum plate and complex aircraft fitting-lug specimens under varying temperature and loading variations.

  19. The relationship between UT reported size and actual size of the defects in rotor forgings

    2003-01-01

    In order to evaluate the reliability of rotor forgings, it is very important to know the actual size of the defects in the rotor forgings. The determination of the defect size requires the accurate non-destructive measurement. However, there may be some differences between the reported size with the ultrasonic non-destructive testing method and the actual size of defects. These differences may be a severe cause of errors in evaluation of rotor forgings. So, the calculated size with 'Master Curve' considering safety factor, which is usually larger than the reported size, has been used in evaluation of rotor forgings. The relation between the EFBH (Equivalent Flat Bottom Hole) size measured by non-destructive method and the actual size by destructive method in many rotors manufactured at Doosan was investigated. In this investigation 'Master Curve' compensating the differences between UT reported size and actual size of defects in our rotor forgings was obtainable. The applicability of this 'Master Curve' as a way of calculating the actual defect size was also investigated. For the evaluation of rotor forgings, it is expected that this 'Master Curve' may be used to determine the accurate actual size of defects.

  3. Histochemistry in Biology and Medicine: A Message From the Citing Journals

    Science.gov (United States)

    2015-01-01

    Especially in recent years, biomedical research has taken advantage of the progress in several disciplines, among which microscopy and histochemistry. To assess the influence of histochemistry in the biomedical field, the articles published during the period 2011-2015 have been selected from different databases and grouped by subject categories. As expected, biological and biomedical studies where histochemistry has been used as a major experimental approach include a wide range of basic and applied researches on both humans and other animal or plant organisms. To better understand the impact of histochemical publications onto the different biological and medical disciplines, it was useful to look at the journals where the articles published in a multidisciplinary journal of histochemistry have been cited: it was observed that, in the five-years period considered, 20% only of the citations were in histochemical periodicals, the remaining ones being in journals of Cell & Tissue biology, general and experimental Medicine, Oncology, Biochemistry & Molecular biology, Neurobiology, Anatomy & Morphology, Pharmacology & Toxicology, Reproductive biology, Veterinary sciences, Physiology, Endocrinology, Tissue engineering & Biomaterials, as well as in multidisciplinary journals. It is easy to foresee that also in the future the histochemical journals will be an attended forum for basic and applied scientists in the biomedical field. It will be crucial that these journals be open to an audience as varied as possible, publishing articles on the application of refined techniques to very different experimental models: this will stimulate non-histochemist scientists to approach histochemistry whose application horizon could expand to novel and possibly exclusive subjects.

    Busch, Fredric N

    2017-01-01

    In psychoanalytic theory, the importance of actual neuroses-considered to be devoid of psychic content-diminished as Freud and subsequent analysts focused on unconscious intrapsychic conflict. This paper explores the relationship between actual neurotic and unrepresented states, which are believed to be best addressed through attention to countertransference, intersubjectivity, and enactments rather than interpretation of intrapsychic conflict. Models suggesting how actual neurotic states and symbolized intrapsychic conflict may interact with each other and environmental stressors are described. Symbolizing actual neurotic states and establishing meaningful linkages between somatic/affective experiences and intrapsychic conflict are viewed as necessary for effective treatment of many disorders. © 2017 The Psychoanalytic Quarterly, Inc.

    Full Text Available The journal is fundamental to formal scholarly communication. This research reports highlights and preliminary findings from an empirical study of scholarly electronic journals. The purpose of the research is to assess the impact of electronic journals (e-journals on scholarly communication, by measuring the extent to which they are being cited in the literature, both print and electronic. The intent is to provide a snapshot of the impact e-journals were having on scholarly communication at a given point in time, roughly the end of 1995. This study provides one measure of that impact, specifically on the formal, as opposed to informal, communication process. The study also examines the forms in which scholars cite e-journals, the accuracy and completeness of citations to e-journals, and practical difficulties faced by scholars and researchers who wish to retrieve e-journals through the networks.

    Full Text Available Abstract Background Journal advertising is used by pharmaceutical companies to disseminate medicine information to doctors. The quality of claims, references and the presentation of risk results in Australia and the US has been questioned in several studies. No recent evidence is available on the quality of claims, references and the presentation of risk results in journal advertising in Australia and the US and no Malaysian data have been published. The aim of this study was to compare the quality of claims, references and the presentation of risk results in journal advertising in these three countries. Methods A consecutive sample of 85 unique advertisements from each country was selected from journal advertising published between January 2004 to December 2006. Claims, references and the presentation of risk results in medical journal advertising were compared between the three countries. Results Less than one-third of the claims were unambiguous claims (Australia, 30%, Malaysia 17%, US, 23%. In Malaysia significantly less unambiguous claims were provided than in Australia and the US (P Conclusions The majority of claims were vague suggesting poor quality of claims in journal advertising in these three countries. Evidence from a randomized controlled trial, systematic review or meta- analysis was commonly cited to support claims. However, the more frequent use of data that have not been published and independently reviewed in the US compared to Australia and Malaysia raises questions on the quality of references in the US. The use of relative rather than absolute benefits may overemphasize the benefit of medicines which may leave doctors susceptible to misinterpreting information.

    With the growing focus on continuous professional development, demands placed on nurses to uphold nursing competence have been increasing. This study examined how nurses with different lengths of clinical experience perceived the relationship between their actual competence and the competence they felt was demanded of them, and how this relationship was related to their turnover intentions. Survey questionnaires were distributed to 1,377 nurses, of whom 765 returned usable completed forms. The results showed that across all the groups of clinical experience, nurses perceived the demanded competence levels to be higher than their actual competence levels. However, turnover intentions were not related to nurses' perceptions of demanded competence and were negatively related to perceptions of actual competence. The levels of competence demanded should not be considered as threats for nurses. Improving nurses' competence may reduce their turnover intentions.

    Poor Medicare knowledge is associated with worse health outcomes, especially in low-income patients. We examined the association of health literacy and cognition with actual and perceived Medicare knowledge in a sample of inner-city older adults. We conducted a cross-sectional analysis of data on 336 adults ages 65 years and older with Medicare coverage recruited from senior centers and low-income housing facilities in Manhattan, New York. Actual Medicare knowledge was determined by a summary score of 9 true/false questions about the Medicare program and perceived Medicare knowledge with a single item. Validated measures were used to assess health literacy and general cognition. Among respondents, 63.1% had high actual Medicare knowledge, and 36.0% believed that they knew what they needed to know about Medicare. Actual and perceived Medicare knowledge were poorly correlated (r = -.01, p > .05). In multivariable models, low health literacy was significantly associated with actual Medicare knowledge (β = -8.30, SE = 2.71, p information about the Medicare program and diminish their ability to make fully informed choices.

    This study is the first to compare the accuracy of self-reported with actual monetary outcomes of online fixed odds sports betting, live action sports betting, and online casino gambling at the individual level of analysis. Subscribers to bwin.party digital entertainment's online gambling service volunteered to respond to the Brief Bio-Social Gambling Screen and questions about their estimated gambling results on specific games for the last 3 or 12 months. We compared the estimated results of each subscriber with his or her actual betting results data. On average, between 34% and 40% of the participants expressed a favorable distortion of their gambling outcomes (i.e., they underestimated losses or overestimated gains) depending on the time period and game. The size of the discrepancy between actual and self-reported results was consistently associated with the self-reported presence of gambling-related problems. However, the specific direction of the reported discrepancy (i.e., favorable vs. unfavorable bias) was not associated with gambling-related problems.

    Full Text Available This study reviews the potential of tablet technology for teaching and learning. In autumn 2012, we conducted a focused survey comprising quantitative and qualitative questions with Finnish teachers (N = 171, from 54 schools. We focused on perceived pedagogical opportunities and the actualized pedagogical potential of tablets at schools. The survey results indicate that the actual usefulness of tablets in schools was significantly less than what teachers perceived as the pedagogical potential. However, the results demonstrate the positive impact these devices are having on teaching and learning, as well as prompting changes in pedagogical perspectives. Teachers stated that tablets can diversify and enhance teaching and learning in many ways, particularly in supporting learners’ motivation and independent learning, and promoting engaging teaching methods. Nevertheless, teachers voiced concern that the student-to-device ratio at the moment is too low, thus serving as a barrier to widespread use of tablets.

    Pair formation, acquiring a mate to form a reproductive unit, is a complex process. Mating preferences are a step in this process. However, due to constraining factors such as availability of mates, rival competition, and mutual mate choice, preferred characteristics may not be realised in the actual partner. People value height in their partner and we investigated to what extent preferences for height are realised in actual couples. We used data from the Millennium Cohort Study (UK) and comp...

    Full Text Available Bibliometrics deals with the quantitative analysis of some distinct characteristics (i.e. authorship, subject, publication information, and cited sources of publications or documents. The process of scientific communication in various fields can be investigated using bibliometric data obtained in such studies. This paper analyzes the bibliometric features of 100 master’s and doctoral dissertations completed at the Department of Library Science of Hacettepe University between 1974 and 2002. An average dissertation was 171 pages long and contained 70 citations. Doctoral dissertations were twice as long as master’s dissertations (275 pages as opposed to 142 pages. Similarly, the average number of citations in a doctoral dissertation was 2.5 times higher than that of a master’s dissertation. Monographs received half of all citations (7019 while journals did 42%, dissertations and electronic publications 3% each, and “other” documents such as unpublished manuscripts 2%. The Türk Kütüphaneciliği (the journal Turkish Librarianship, Resmî Gazete (Official Gazette, College & Research Libraries, Library Trends, Library Journal, Journal of the American Society for Information Science and Unesco Bulletin for Libraries were among the most frequently cited journals. Articles that appeared in the top four and top 38 journals received 32% and 67% of all citations, respectively. The distribution of citations to foreign journals fits the Bradford’s Law of Scattering. The mean half-life of sources cited in dissertations was 9 years. Sources cited in master’s dissertations were younger than those of doctoral dissertations. The great majority of cited resources in dissertations had single authorship. Findings obtained in this study can be used to evaluate the library collections as well as to develop a core journals list in librarianship.

    The main purpose of this study is to present a calculating procedure for the components of the radiation balance - actual, long-wave and net radiation calculation, using the sunshine duration and the standard meteorological information, through a previously prepared program product.To calculate the actual solar radiation using the total cloudiness only, an empirical regression model has been developed. The results of the coefficient of correlation R(0.75-0.88), respectively for the spring and summer periods (March-May; June-August) show the adequacy of the chosen model. The verification of the model on the independent experimental material prove that the approach that authors suggested, can be successfully applied to the calculation of the actual radiation of the current place

  17. Actual preferences for EV households in Denmark and Sweden

    Jensen, Anders Fjendbo; Haustein, Sonja; Cherchi, Elisabetta

    , as the EV market is still quite immature in most countries, lack of data on EV users is a common problem for researchers. Data on EV purchase and use have thus often been collected by means of data from intentional statements (see e.g. Bühler et al. 2014), stated preferences (see e.g. Bunch et al. 1993......; Hidrue et al. 2011; Jensen et al. 2014) and EV vehicle trials (Golob & Gould 1998; Franke & Krems 2013; Jensen et al. 2014). While such studies have provided important insight into various areas of the EV market, the fact that the results are not based on actual behaviour means that they are subject...... to a high degree of uncertainty. Being the global EV market forerunner, Norway has a better foundation for studying the EV market based on actual EV owners. On these grounds, Klöckner et al. (2013), studied differences in car use between EV and conventional vehicle (CV) users. Also in Norway, Mersky et al...

    The ASSESS Neutralization module (Neutralization) is part of the Analytic System and Software for Evaluation of Safeguards and Security (ASSESS), a vulnerability assessment tool. Neutralization models a fire fight between security inspectors (SIs) and adversaries. This paper reports that a comparison has been made between actual outcomes of police and small military engagements and the results predicted by the Neutralization module for similar scenarios. The results of this comparison show a surprising correlation between predicted outcomes (based on numbers of combatants, weapon types, and exposures, etc.) and the actual outcomes of the engagements analyzed. The importance of this analysis is that given the defenders have intelligence on actual adversary characteristics or are protecting against a design basis threat, defense capabilities can be evaluated before an engagement. Results could then be used to develop a favorable probability of a desired outcome. For example, law enforcement agencies are frequently able to compile the number of criminals, types of weaponry, willingness to use force, etc., from analysis of crime scenes

    Weight reduction that corresponds with lifestyle modification is difficult to foster. The theory of planned behaviour has been actively cited in explaining health-related behaviour. This review evaluated the application of the theory of planned behaviour to weight-loss behaviour. Among the three reviewed papers, cross-sectional survey designs and subjective outcome measurements were commonly applied. All of the studies recruited obese female adults as participants, limiting the generalisabili...

    Given that children with low movement skill competence engage in less physical activity, it is important to understand how children's perceptions relate to actual movement competence. This study examined relationships between (i) children's self-perception and objective assessments of their movement skills (object control and locomotor) and (ii) parents' perceptions of the children's movement skills and objective assessment. Children's skill perceptions were assessed using the Pictorial Scale of Perceived Movement Skill Competence for Young Children. Parent perceptions of their child's skills were assessed using a modified version of this instrument. The Test of Gross Motor Development-2nd edition assessed children's skills objectively. Participants were 136 Australian children (51% boys; M=6.5 yr., SD=1.1) and 133 parents. Regression analyses (by sex) examined the relationship between perceptions and children's scores for actual skilled performance. Boys' perceptions were associated with their actual object control ability. Parents accurately perceived boys' object control ability and girls' locomotor ability, but not the reverse. This suggests interventions aiming to improve children's movement skills could target parents and be designed to teach parents how to recognize good and poor skill performance in their children.

    Quantifying the preferred transition speed (PTS) from walking to running has provided insight into the underlying mechanics of locomotion. The dynamic similarity hypothesis suggests that the PTS should occur at the same Froude number across gravitational environments. In normal Earth gravity, the PTS occurs at a Froude number of 0.5 in adult humans, but previous reports found the PTS occurred at Froude numbers greater than 0.5 in simulated lunar gravity. Our purpose was to (1) determine the Froude number at the PTS in actual lunar gravity during parabolic flight and (2) compare it with the Froude number at the PTS in simulated lunar gravity during overhead suspension. We observed that Froude numbers at the PTS in actual lunar gravity (1.39±0.45) and simulated lunar gravity (1.11±0.26) were much greater than 0.5. Froude numbers at the PTS above 1.0 suggest that the use of the inverted pendulum model may not necessarily be valid in actual lunar gravity and that earlier findings in simulated reduced gravity are more accurate than previously thought. © 2014.

    To determine the associations between young children's actual and perceived object control and locomotor skills and physical activity and whether associations differ by sex. Cross sectional study. A total of 136 children consented. Children had actual skill (Test of Gross Motor Development-2), perceived skill (Pictorial Scale of Perceived Movement Skill Competence for Young Children), and moderate- to vigorous-intensity physical activity (MVPA) (accelerometers) assessed. Independent t-tests assessed sex differences. A regression (with MVPA as the outcome) was performed with all predictor variables (i.e. Actual Object Control, Actual Locomotor, Perceived Object Control, and Perceived Locomotor). Model 2 also adjusted for age, sex, accelerometer wear time and whether the child was from an English speaking background. Interaction terms between the respective actual or perceived skill factor and sex were added to assess sex differences. Analyses were conducted on 109 children (59 boys, 50 girls; mean age=6.5 years, SD=1.0). Boys had higher actual and perceived object control skill and were more active by an average of 19min per day. There were no sex differences in locomotor skills. There were no associations between skill factors and MVPA, except for girls, where locomotor skill was a significant predictor of MVPA (B=3.66, p=0.016). Actual rather than perceived skill competence was more important to MVPA in this sample. Locomotor skill competence may be more important than object control skill competence for girls as they may engage in types of physical activity that do not require object control mastery.

    Full Text Available Abstract Background In most phase I oncology trials, it is often stated that the dose increments follow a “modified-Fibonacci sequence”. This term, however, is vague. Methods To better characterize this sequence, we reviewed 81 phase I trials based on this concept. Results Out of 198 phase I oncology trials, 81 (41% are based on modified-Fibonacci series. Actual incremental ratios varied in a large range from 0.80 to 2.08. The median of actual increments was about 2.00, 1.50, 1.33, 1.33, 1.33, 1.33, 1.30, 1.35…. The “modified Fibonacci-sequence” gathers heterogeneous variation of the genuine sequence, which does not tend to a constant number at higher dose-levels. Conclusion This confusing term should be avoided.

    Introduction: Johnson Space Center (JSC) offers two extensive libraries that contain journals, research literature and electronic resources. Searching capabilities are available to those individuals residing onsite or through a librarian s search. Many individuals have rich collections of references, but no mechanisms to share reference libraries across researchers, projects, or directorates exist. Likewise, information regarding which references are provided to which individuals is not available, resulting in duplicate requests, redundant labor costs and associated copying fees. In addition, this tends to limit collaboration between colleagues and promotes the establishment of individual, unshared silos of information The Integrated Medical Model (IMM) team has utilized a centralized reference management tool during the development, test, and operational phases of this project. The Enterprise Reference Library project expands the capabilities developed for IMM to address the above issues and enhance collaboration across JSC. Method: After significant market analysis for a multi-user reference management tool, no available commercial tool was found to meet this need, so a software program was built around a commercial tool, Reference Manager 12 by The Thomson Corporation. A use case approach guided the requirements development phase. The premise of the design is that individuals use their own reference management software and export to SharePoint when their library is incorporated into the Enterprise Reference Library. This results in a searchable user-specific library application. An accompanying share folder will warehouse the electronic full-text articles, which allows the global user community to access full -text articles. Discussion: An enterprise reference library solution can provide a multidisciplinary collection of full text articles. This approach improves efficiency in obtaining and storing reference material while greatly reducing labor, purchasing and

    We report dynamic changes in the priorities for strategic risks faced by international water utilities over a 10year period, as cited by managers responsible for managing them. A content analysis of interviews with three cohorts of risk managers in the water sector was undertaken. Interviews probed the focus risk managers' were giving to strategic risks within utilities, as well as specific questions on risk analysis tools (2005); risk management cultures (2011) and the integration of risk management with corporate decision-making (2015). The coding frequency of strategic (business, enterprise, corporate) risk terms from 18 structured interviews (2005) and 28 semi-structured interviews (12 in 2011; 16 in 2015) was used to appraise changes in the perceived importance of strategic risks within the sector. The aggregated coding frequency across the study period, and changes in the frequency of strategic risks cited at three interview periods identified infrastructure assets as the most significant risk over the period and suggests an emergence of extrinsic risk over time. Extended interviews with three utility risk managers (2016) from the UK, Canada and the US were then used to contextualise the findings. This research supports the ongoing focus on infrastructure resilience and the increasing prevalence of extrinsic risk within the water sector, as reported by the insurance sector and by water research organisations. The extended interviews provided insight into how strategic risks are now driving the implementation agenda within utilities, and into how utilities can secure tangible business value from proactive risk governance. Strategic external risks affecting the sector are on the rise, involve more players and are less controllable from within a utility's own organisational boundaries. Proportionate risk management processes and structures provide oversight and assurance, whilst allowing a focus on the tangible business value that comes from managing strategic

    retrospective study examined the OR turnaround data of 875 elective surgery cases scheduled at the Marienhospital, Vechta, Germany, between July and October 2014. The frequency distributions of planned and actual OR turnaround times were compared and correlations between turnaround times and various factors were established, including the time of day of the procedure, patient age and the planned duration of the surgery. Results: There was a significant difference between mean planned and actual OR turnaround times (0.32 versus 0.64 hours; P <0.001. In addition, significant correlations were noted between actual OR turnaround times and the time of day of the surgery, patient age, actual duration of the procedure and staffing changes affecting the surgeon or the medical specialty of the surgery (P <0.001 each. The quotient of actual/planned OR turnaround times ranged from 1.733–3.000. Conclusion: Significant discrepancies between planned and actual OR turnaround times were noted during the study period. Such findings may be potentially used in future studies to establish a tool to improve OR planning, measure OR management performance and enable benchmarking.

    For the calculation of the parasite resistance of an airplane, a knowledge of the resistance of the individual structural and accessory parts is necessary. The most reliable basis for this is given by tests with actual airplane parts at airspeeds which occur in practice. The data given here relate to the landing gear of a Siemanms-Schuckert DI airplane; the landing gear of a 'Luftfahrzeug-Gesellschaft' airplane (type Roland Dlla); landing gear of a 'Flugzeugbau Friedrichshafen' G airplane; a machine gun, and the exhaust manifold of a 269 HP engine.
