Bibliometric indices are a widely used measure of research impact. The aim of the current study was to identify and characterise the top one hundred most-cited research articles in the topic of chronotype research. A search of the Thomson Reuters Web of Science database returned 974 eligible articles (published between 1990 and 2016). Citations for the 100 most-cited articles ranged between 438 and 29. The most represented journal was Chronobiology International (n = 30). Nearly 50% of articles originated in Germany and the U.S. The bibliometrics reported identify key publications and provide insight into trends within the topic of chronotype research.

Bibliometrics is a science which evaluates the impact of the scientific work of a journal or of an author, using mathematical and statistical tools. Impact Factor (IF) is the first bibliometric parameter created, and after it many others have been progressively conceived in order to go beyond its limits. Currently bibliometric indexes are used for academic purposes, among them to evaluate the eligibility of a researcher to compete for the National Scientific Qualification, in order to access to competitive exams to become professor. Aim of this study is to identify the most relevant bibliometric indexes and to summarized their characteristics. A revision of bibliometric indexes as been conducted, starting from the classic ones and completing with the most recent ones. The two most used bibliometric indexes are the IF, which measures the scientific impact of a periodical and bases on Web of Science citation database, and the h-index, which measures the impact of the scientific work of a researcher, basing on Scopus database. Besides them other indexes have been created more recently, such as the SCImago Journal Rank Indicator (SJR), the Source Normalised Impact per Paper (SNIP) and the CiteScore index. They are all based on Scopus database and evaluate, in different ways, the citational impact of a periodic. The i10-index instead is provided from Google Scholar database and allows to evaluate the impact of the scientific production of a researcher. Recently two softwares have been introduced: the first one, Publish or Perish, allows to evaluate the scientific work of a researcher, through the assessment of many indexes; the second one, Altmetric, measure the use in the Web of the academic papers, instead of measuring citations, by means of alternative metrics respect to the traditional ones. Each analized index shows advantages but also criticalities. Therefore the combined use of more than one indexes, citational and not, should be preferred, in order to correctly evaluate the work of reserchers and to finally improve the quality and the development of scientific research.

Social media, defined as interactive Web applications, have been on the rise globally, particularly among adults. The objective of this study was to investigate the trend of the literature related to the most used social network worldwide (i.e. Facebook, Twitter, LinkedIn, Snapchat, and Instagram) in the field of psychology. Specifically, this study will assess the growth in publications, citation analysis, international collaboration, author productivity, emerging topics and the mapping of frequent terms in publications pertaining to social media in the field of psychology. Publications related to social media in the field of psychology published between 2004 and 2014 were obtained from the Web of Science. The records extracted were analysed for bibliometric characteristics such as the growth in publications, citation analysis, international collaboration, emerging topics and the mapping of frequent terms in publications pertaining to social media in the field of psychology. VOSviewer v.1.6.5 was used to construct scientific maps. Overall, 959 publications were retrieved during the period between 2004 and 2015. The number of research publications in social media in the field of psychology showed a steady upward growth. Publications from the USA accounted for 57.14% of the total publications and the highest h -index (48).The most common document type was research articles (873; 91.03%). Over 99.06% of the publications were published in English. Computers in Human Behavior was the most prolific journal. The University of Wisconsin - Madison ranked first in terms of the total publications (n = 39). A visualisation analysis showed that personality psychology, experimental psychology, psychological risk factors, and developmental psychology were continual concerns of the research. This is the first study reporting the global trends in the research related to social media in the psychology field. Based on the raw data from the Web of Science, publication characteristics such as quality and quantity were assessed using bibliometric techniques over 12 years. The USA and its institutions play a dominant role in this topic. The most preferred topics related to social media in psychology are personality psychology, experimental psychology, psychological risk factors, and developmental psychology.

The National Minimum Dataset for Social Care (NMDS-SC) has provided detailed data since 2006 on the workforce for adult social care services in England. In 2012, the organisation responsible for the data set commissioned an evaluation into the impact of the data set on researchers and policymakers. Discusses how a novel wide-ranging bibliometric approach, complemented by interviews of key informants, demonstrated the developing impact of the data set. The evaluation comprised web metrics to assess NMDS-SC-related traffic on relevant websites; bibliometrics to assess the use of NMDS-SC data in scholarly publications and grey literature; telephone interviews with 12 key users of the data set; and an online survey completed by 24 key users of the data set. A theoretical framework for research impact was used. The web metrics demonstrated increase in traffic on the relevant pages of the organisation's website. There were references to the data set in 175 separate publications (15% from academic journals, 50% as policy/practice reports and 35% as media communications. Interviews evidenced many impacts, for example provision of robust data for secondary analysis that challenged conventional views about the social care workforce. Bibliometrics plus interviews provided a rounded picture of the data set's impact. © 2013 The authors. Health Information and Libraries Journal © 2013 Health Libraries Group.

On the bibliometric coordinates of four different research fields in Geography.

PubMed

Gorraiz, Juan; Gumpenberger, Christian; Glade, Thomas

This study is a bibliometric analysis of the highly complex research discipline Geography. In order to identify the most popular and most cited publication channels, to reveal publication strategies, and to analyse the discipline's coverage within publications, the three main data sources for citation analyses, namely Web of Science, Scopus and Google Scholar, have been utilized. This study is based on publication data collected for four individual evaluation exercises performed at the University of Vienna and related to four different subfields: Geoecology, Social and Economic Geography, Demography and Population Geography, and Economic Geography. The results show very heterogeneous and individual publication strategies, even in the same research fields. Monographs, journal articles and book chapters are the most cited document types. Differences between research fields more related to the natural sciences than to the social sciences are clearly visible, but less considerable when taking into account the higher number of co-authors. General publication strategies seem to be established for both natural science and social sciences, however, with significant differences. While in natural science mainly publications in international peer-reviewed scientific journals matter, the focus in social sciences is rather on book chapters, reports and monographs. Although an "iceberg citation model" is suggested, citation analyses for monographs, book chapters and reports should be conducted separately and should include complementary data sources, such as Google Scholar, in order to enhance the coverage and to improve the quality of the visibility and impact analyses. This is particularly important for social sciences related research within Geography.

Background Bibliometrics is defined as the use of statistical methods in the analysis of a body of literature to reveal the historical development of subject fields and patterns of authorship, publication, and use. Our objective was to characterize Spanish scientific output in Dentistry through the analysis of Web of Science database in a 20-year period. By means of a bibliometric study documents were statistically analyzed using indicators that showed quantitative and qualitative aspects of the production. Specifically, time course of the scientific production within the time span was analysed, as were the journals where the article was published and the categories of Journal Citation Reports (JCR) in which they belong, thematic areas, authorship, and finally authors and institutions with the highest production in Spain. Material and Methods By means of the design of a specific search strategy previously described in the scientific literature, we recovered all citable documents about Dentistry signed by Spanish researchers and included in the WoS database between 1993 and 2012. Results A total of 3006 documents fulfilled the search criteria, of which 2449 (81.5%) were published in journals within the category Dentistry Oral Surgery and Medicine and 557 (18.5%) within other categories of the JCR. During the four quinquenniums studied, the production increased quantitatively (8.6-fold) and qualitatively. Finally, the universities of Granada and Complutense of Madrid were the institutions with the highest production and most prolific authors. Conclusions The Spanish dental production sharply increased in the last two decades, reaching quantitative and qualitative levels similar to those of the other medical specialties in the country. Key words:Dental research, dentistry, publications, Journal impact factor, bibliometrics, biomedical research, Spanish dental production. PMID:26827056

One way to initiate the reconstruction of molecular circuits is by using automated text-mining techniques. Developing more efficient methods for such reconstruction is a topic of active research, and those methods are typically included by bioinformaticians in pipelines used to mine and curate large literature datasets. Nevertheless, experimental biologists have a limited number of available user-friendly tools that use text-mining for network reconstruction and require no programming skills to use. One of these tools is Biblio-MetReS. Originally, this tool permitted an on-the-fly analysis of documents contained in a number of web-based literature databases to identify co-occurrence of proteins/genes. This approach ensured results that were always up-to-date with the latest live version of the databases. However, this 'up-to-dateness' came at the cost of large execution times. Here we report an evolution of the application Biblio-MetReS that permits constructing co-occurrence networks for genes, GO processes, Pathways, or any combination of the three types of entities and graphically represent those entities. We show that the performance of Biblio-MetReS in identifying gene co-occurrence is as least as good as that of other comparable applications (STRING and iHOP). In addition, we also show that the identification of GO processes is on par to that reported in the latest BioCreAtIvE challenge. Finally, we also report the implementation of a new strategy that combines on-the-fly analysis of new documents with preprocessed information from documents that were encountered in previous analyses. This combination simultaneously decreases program run time and maintains 'up-to-dateness' of the results. http://metres.udl.cat/index.php/downloads, metres.cmb@gmail.com.

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

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.

The aim of this study is to review the features, benefits and limitations of the new scientific evaluation products derived from Google Scholar, such as Google Scholar Metrics and Google Scholar Citations, as well as the h-index, which is the standard bibliometric indicator adopted by these services. The study also outlines the potential of this new database as a source for studies in Biomedicine, and compares the h-index obtained by the most relevant journals and researchers in the field of intensive care medicine, based on data extracted from the Web of Science, Scopus and Google Scholar. Results show that although the average h-index values in Google Scholar are almost 30% higher than those obtained in Web of Science, and about 15% higher than those collected by Scopus, there are no substantial changes in the rankings generated from one data source or the other. Despite some technical problems, it is concluded that Google Scholar is a valid tool for researchers in Health Sciences, both for purposes of information retrieval and for the computation of bibliometric indicators.

[The long pilgrimage of Spanish biomedical journals toward excellence. Who helps? Quality, impact and research merit].

Alfonso, Fernando

2010-03-01

Biomedical journals must adhere to strict standards of editorial quality. In a globalized academic scenario, biomedical journals must compete firstly to publish the most relevant original research and secondly to obtain the broadest possible visibility and the widest dissemination of their scientific contents. The cornerstone of the scientific process is still the peer-review system but additional quality criteria should be met. Recently access to medical information has been revolutionized by electronic editions. Bibliometric databases such as MEDLINE, the ISI Web of Science and Scopus offer comprehensive online information on medical literature. Classically, the prestige of biomedical journals has been measured by their impact factor but, recently, other indicators such as SCImago SJR or the Eigenfactor are emerging as alternative indices of a journal's quality. Assessing the scholarly impact of research and the merits of individual scientists remains a major challenge. Allocation of authorship credit also remains controversial. Furthermore, in our Kafkaesque world, we prefer to count rather than read the articles we judge. Quantitative publication metrics (research output) and citations analyses (scientific influence) are key determinants of the scientific success of individual investigators. However, academia is embracing new objective indicators (such as the "h" index) to evaluate scholarly merit. The present review discusses some editorial issues affecting biomedical journals, currently available bibliometric databases, bibliometric indices of journal quality and, finally, indicators of research performance and scientific success.

Objectives To compare H index scores for healthcare researchers returned by Google Scholar, Web of Science and Scopus databases, and to assess whether a researcher's age, country of institutional affiliation and physician status influences calculations. Subjects and Methods One hundred and ninety-five Nobel laureates in Physiology and Medicine from 1901 to 2009 were considered. Year of first and last publications, total publications and citation counts, and the H index for each laureate were calculated from each database. Cronbach's alpha statistics was used to measure the reliability of H index scores between the databases. Laureate characteristic influence on the H index was analysed using linear regression. Results There was no concordance between the databases when considering the number of publications and citations count per laureate. The H index was the most reliably calculated bibliometric across the three databases (Cronbach's alpha = 0.900). All databases returned significantly higher H index scores for younger laureates (p < 0.0001). Google Scholar and Web of Science returned significantly higher H index for physician laureates (p = 0.025 and p = 0.029, respectively). Country of institutional affiliation did not influence the H index in any database. Conclusion The H index appeared to be the most consistently calculated bibliometric between the databases for Nobel laureates in Physiology and Medicine. Researcher-specific characteristics constituted an important component of objective research assessment. The findings of this study call to question the choice of current and future academic performance databases. PMID:22964880

Does an expert-based evaluation allow us to go beyond the Impact Factor? Experiences from building a ranking of national journals in Poland.

PubMed

Kulczycki, Emanuel; Rozkosz, Ewa A

2017-01-01

This article discusses the Polish Journal Ranking, which is used in the research evaluation system in Poland. In 2015, the ranking, which represents all disciplines, allocated 17,437 journals into three lists: A, B, and C. The B list constitutes a ranking of Polish journals that are indexed neither in the Web of Science nor the European Reference Index for the Humanities. This ranking was built by evaluating journals in three dimensions: formal, bibliometric, and expert-based. We have analysed data on 2035 Polish journals from the B list. Our study aims to determine how an expert-based evaluation influenced the results of final evaluation. In our study, we used structural equation modelling, which is regression based, and we designed three pairs of theoretical models for three fields of science: (1) humanities, (2) social sciences, and (3) engineering, natural sciences, and medical sciences. Each pair consisted of the full model and the reduced model (i.e., the model without the expert-based evaluation). Our analysis revealed that the multidimensional evaluation of local journals should not rely only on the bibliometric indicators, which are based on the Web of Science or Scopus. Moreover, we have shown that the expert-based evaluation plays a major role in all fields of science. We conclude with recommendations that the formal evaluation should be reduced to verifiable parameters and that the expert-based evaluation should be based on common guidelines for the experts.

Web 2.0 applications in medicine: trends and topics in the literature.

Boudry, Christophe

2015-04-01

The World Wide Web has changed research habits, and these changes were further expanded when "Web 2.0" became popular in 2005. Bibliometrics is a helpful tool used for describing patterns of publication, for interpreting progression over time, and the geographical distribution of research in a given field. Few studies employing bibliometrics, however, have been carried out on the correlative nature of scientific literature and Web 2.0. The aim of this bibliometric analysis was to provide an overview of Web 2.0 implications in the biomedical literature. The objectives were to assess the growth rate of literature, key journals, authors, and country contributions, and to evaluate whether the various Web 2.0 applications were expressed within this biomedical literature, and if so, how. A specific query with keywords chosen to be representative of Web 2.0 applications was built for the PubMed database. Articles related to Web 2.0 were downloaded in Extensible Markup Language (XML) and were processed through developed hypertext preprocessor (PHP) scripts, then imported to Microsoft Excel 2010 for data processing. A total of 1347 articles were included in this study. The number of articles related to Web 2.0 has been increasing from 2002 to 2012 (average annual growth rate was 106.3% with a maximum of 333% in 2005). The United States was by far the predominant country for authors, with 514 articles (54.0%; 514/952). The second and third most productive countries were the United Kingdom and Australia, with 87 (9.1%; 87/952) and 44 articles (4.6%; 44/952), respectively. Distribution of number of articles per author showed that the core population of researchers working on Web 2.0 in the medical field could be estimated at approximately 75. In total, 614 journals were identified during this analysis. Using Bradford's law, 27 core journals were identified, among which three (Studies in Health Technology and Informatics, Journal of Medical Internet Research, and Nucleic Acids Research) produced more than 35 articles related to Web 2.0 over the period studied. A total of 274 words in the field of Web 2.0 were found after manual sorting of the 15,878 words appearing in title and abstract fields for articles. Word frequency analysis reveals "blog" as the most recurrent, followed by "wiki", "Web 2.0", "social media", "Facebook", "social networks", "blogger", "cloud computing", "Twitter", and "blogging". All categories of Web 2.0 applications were found, indicating the successful integration of Web 2.0 into the biomedical field. This study shows that the biomedical community is engaged in the use of Web 2.0 and confirms its high level of interest in these tools. Therefore, changes in the ways researchers use information seem to be far from over.

Current bibliometric analyses of the evolving trends in research scope category across different time periods using the H-classics method in implantology are considerably limited. The purpose of this study was to identify the classic articles in implantology to analyse bibliometric characteristics and associated factors in implantology for the past four decades. H-Classics in implantology were identified within four time periods between 1977 and 2016, based on the h-index from the Scopus ® database. For each article, the principal bibliometric parameters of authorship, geographic origin, country origin, and institute origin, collaboration, centralisation, article type, scope of study and other associated factors were analysed in four time periods. A significant increase in mean numbers of authors per H-Classics was found across time. Both Europe and North America were the most productive region/country and steadily dominated this field in each time period. Collaborations of author, internationally and inter-institutionally had significantly increased across time. A significant decentralisation in authorships, institutes and journals was noted in past four decades. The journal of Clinical Oral Implant Researches has raised its importance for almost 30 years (1987-2016). Research on Complications, peri-implant infection/pathology/therapy had been increasing in production throughout each period. This is the first study to evaluate research trends in implantology in the past 40 years using the H-classics method, which through analysing via principle bibliometric characteristics reflected a historical perspective on evolutionary mainstream in the field. Prominence of research regarding complications may forecast innovative advancements in future. © 2018 John Wiley & Sons Ltd.

Sterken, C.

2011-07-01

The main theme of this paper is truthful communication of scientific results. Therefore, concepts of truth, error, quality and value are elaborated. The following bibliometric parameters are explained: the journal impact factor, the journal cited half-life, and the journal immediacy index, as well as paper counts, citation rates, citation index and the Hirsch index. These bibliometric indices and indicators are illustrated with examples derived from bibliometric analyses of the astronomical literature. Scientific misconduct in the broadest sense is discussed by category: researcher misconduct, author misconduct, referee and grant-reviewer misconduct. But also publisher misconduct, editorial misconduct and mismanagement, and research supervisor misbehavior are dealt with. The overall signatures of scientific misconduct are focused on, as well as the causes and the cures. This is followed by a Section devoted to whistleblowing. The biases of bibliometric indices, and the use and abuse of bibliometrics are illustrated. Moreover, suggestions for remediating the present defective system of bibliometric measurement and evaluation are worked out. Finally, the hopes and concerns of our students - either expressed during or after the lectures, or through subsequent private contacts - are passed on.

Bibliometric analysis on global Behçet disease publications during 1980-2014: is there a Silk Road in the literature?

Behçet disease (BD) is a chronic and multisystemic vasculitis characterized with recurrent oral and genital ulcers, uveitis, arthritis and skin manifestations. The highest prevalence of the disease has been reported in regions historically involved in the Silk Road routes. We aimed to analyse Behçet literature and evaluate whether there is a concordance between ancient Silk Road regions and the distribution of publication productivity. The bibliometric analysis of the publications published during 1980-2014 using Thomson Reuters Web of Science database was performed. We generated infographics of productivity and also analysed the correlations among economical productivities, technological advancement levels and humanity index and productivity performances of 78 countries in Behçet literature. Turkey ranked first in Behçet literature with 1837 articles followed by Japan and the USA. Turkey, Tunisia and Israel occupied the first three places in productivity. Significant correlations were noted between 2014 gross economic and technological indices and publication numbers of the countries. We found that European countries had high productivity, although they had low prevalence of BD.

Objective The present study seeks to extend previous bibliometric studies on eating disorders (EDs) by including a time-dependent analysis of the growth and evolution of multi-author collaborations and their correlation with ED publication trends from 1980 to 2014 (35 years). Methods Using standardized practices, we searched Web of Science (WoS) Core Collection (WoSCC) (indexes: Science Citation Index-Expanded [SCIE], & Social Science Citation Index [SSCI]) and Scopus (areas: Health Sciences, Life Sciences, & Social Sciences and Humanities) to identify a large sample of articles related to EDs. We then submitted our sample of articles to bibliometric and graph theory analyses to identify co-authorship and social network patterns. Results We present a large number of detailed findings, including a clear pattern of scientific growth measured as number of publications per five-year period or quinquennium (Q), a tremendous increase in the number of authors attracted by the ED subject, and a very high and steady growth in collaborative work. Conclusions We inferred that the noted publication growth was likely driven by the noted increase in the number of new authors per Q. Social network analyses suggested that collaborations within ED follow patters of interaction that are similar to well established and recognized disciplines, as indicated by the presence of a “giant cluster”, high cluster density, and the replication of the “small world” phenomenon—the principle that we are all linked by short chains of acquaintances.

Ho, Yuh-Shan; Hartley, James

2016-11-01

Who today are the most highly cited psychologists listed in the Web of Science? This paper reports answers to this question by using the Science Citation Index Expanded to find out. This index covers over 280,350 documents in the Psychology category of the Web of Science from 1900 to 2013 and lists the most highly cited papers published between 1927 and 2012. For example, in 2013, an article published by Jacob Cohen in 1992 obtained (1) the highest ranking with 1,068 citations, (2) the highest for total citations per year, and (3) was ranked 3rd for the total number of citations since publication by 2013. New technology thus provides a seismic shift in the ways that we can obtain and analyse data like these. Indeed, the results for the top 10 articles indicate that practical and methodological papers now receive more citations than the more theoretical papers usually found in earlier surveys. © 2015 The British Psychological Society.

Trends in gel dosimetry: Preliminary bibliometric overview of active growth areas, research trends and hot topics from Gore’s 1984 paper onwards

Baldock, C.

2017-05-01

John Gore’s seminal 1984 paper on gel dosimetry spawned a vibrant research field ranging from fundamental science through to clinical applications. A preliminary bibliometric study was undertaken of the gel dosimetry family of publications inspired by, and resulting from, Gore’s original 1984 paper to determine active growth areas, research trends and hot topics from Gore’s paper up to and including 2016. Themes and trends of the gel dosimetry research field were bibliometrically explored by way of co-occurrence term maps using the titles and abstracts text corpora from the Web of Science database for all relevant papers from 1984 to 2016. Visualisation of similarities was used by way of the VOSviewer visualisation tool to generate cluster maps of gel dosimetry knowledge domains and the associated citation impact of topics within the domains. Heat maps were then generated to assist in the understanding of active growth areas, research trends, and emerging and hot topics in gel dosimetry.

The objective of this paper is to provide a detailed evaluation of type 2 diabetes mellitus research output from 1951-2012, using large-scale data analysis, bibliometric indicators and density-equalizing mapping. Data were retrieved from the Science Citation Index Expanded database, one of the seven curated databases within Web of Science. Using Boolean operators "OR", "AND" and "NOT", a search strategy was developed to estimate the total number of published items. Only studies with an English abstract were eligible. Type 1 diabetes and gestational diabetes items were excluded. Specific software developed for the database analysed the data. Information including titles, authors’ affiliations and publication years were extracted from all files and exported to excel. Density-equalizing mapping was conducted as described by Groenberg-Kloft et al, 2008. A total of 24,783 items were published and cited 476,002 times. The greatest number of outputs were published in 2010 (n=2,139). The United States contributed 28.8% to the overall output, followed by the United Kingdom (8.2%) and Japan (7.7%). Bilateral cooperation was most common between the United States and United Kingdom (n=237). Harvard University produced 2% of all publications, followed by the University of California (1.1%). The leading journals were Diabetes, Diabetologia and Diabetes Care and they contributed 9.3%, 7.3% and 4.0% of the research yield, respectively. In conclusion, the volume of research is rising in parallel with the increasing global burden of disease due to type 2 diabetes mellitus. Bibliometrics analysis provides useful information to scientists and funding agencies involved in the development and implementation of research strategies to address global health issues.

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.

The bibliometric analysis of production and impact of documents by knowledge area is a quantitative and qualitative indicator of research activity in this field. The aim of this article is to determine the contribution of Spanish research institutions in Infectious Diseases and Microbiology in recent years. Documents published in the journals included in the categories "Infectious Diseases" and "Microbiology" of the Web of Science (Science Citation Index Expanded) of the ISI Web of Knowledge from the year 2000-2013 were analysed. In Infectious Diseases, Spain ranked fourth worldwide, and contributed 5.7% of the 233,771 documents published in this specialty. In Microbiology, Spain was in sixth place with a production rate of 5.8% of the 149,269 documents of this category. The Spanish production increased over the study period, both in Infectious Diseases and Microbiology, from 325 and 619 documents in 2000 to 756 and 1245 documents in 2013, with a growth rate of 131% and 45.8%, respectively. The journal with the largest number of documents published was Enfermedades Infecciosas y Microbiología Clínica, with 8.6% and 8.2% of papers published in the categories of Infectious Diseases and Microbiology, respectively, and was the result of international collaborations, especially with institutions in the United States. The "index h" was 116 and 139 in Infectious Diseases and Microbiology, placing Spain in fifth place in both categories within countries of the European Union. In recent years, Spanish research in Infectious Diseases and Microbiology has reached a good level of production and international visibility, reaching a global leadership position. Copyright © 2015.

The aim of the study was to quantify the scientific productivity of researchers, organizations, and regions in Spain that publish articles on implantology in dental journals indexed in Journal Citation Reports. A search was conducted among the core collection of Thomson Reuters' Web of Science database, on the basis of its broad thematic and geographic coverage of health sciences. The search identified original articles - the main vehicle for the dissemination of research results. The search was conducted in July 2016, applying the truncated search term 'implant*' to locate original articles on implantology and its derivative forms. The search was conducted within the topic field (title, keywords and abstract) and two inclusion criteria were applied: documents denominated as articles were included; and articles categorized as Web of Science Medicine Dentistry and Oral Surgery. Finally only articles for which one of the participating organizations was located in Spain were selected. The final search identified a total of 774 records. The period 1988 to 2015 saw an exponential growth in scientific production, especially during the last 10 years. Clinical Oral Implants Research and Medicina Oral Patologia Oral y Cirugia Bucal (Oral Medicine, Oral Pathology, and Oral Surgery) were the most productive journals. Collaborative networks among authors and among institutions increased and this increase was related to the improving quality of the publications. Bibliometric analysis revealed a significant growth in the quantity and quality of Spanish implantology literature. Most key bibliometric indicators demonstrated upward trends. Key words: Bibliometric analysis, publication, keywords, implantology, implant.

Citation metrics and h indices differ using different bibliometric databases. We compiled the number of publications, number of citations, h index and year since the first publication from 340 soil researchers from all over the world. On average, Google Scholar has the highest h index, number of publications and citations per researcher, and the Web of Science the lowest. The number of papers in Google Scholar is on average 2.3 times higher and the number of citations is 1.9 times higher compared to the data in the Web of Science. Scopus metrics are slightly higher than that of the Web of Science. The h index in Google Scholar is on average 1.4 times larger than Web of Science, and the h index in Scopus is on average 1.1 times larger than Web of Science. Over time, the metrics increase in all three databases but fastest in Google Scholar. The h index of an individual soil scientist is about 0.7 times the number of years since his/her first publication. There is a large difference between the number of citations, number of publications and the h index using the three databases. From this analysis it can be concluded that the choice of the database affects widely-used citation and evaluation metrics but that bibliometric transfer functions exist to relate the metrics from these three databases. We also investigated the relationship between journal’s impact factor and Google Scholar’s h5-index. The h5-index is a better measure of a journal’s citation than the 2 or 5 year window impact factor. PMID:24167778

Neural regeneration following nerve injury is an emerging field that attracts extending interests all over the world. To use bibliometric indexes to track studies focusing on neural regeneration, and to investigate the relationships among geographic origin, countries and institutes, keywords in the published articles, and especially focus on the region distribution, institution distribution, as well as collaborations in Chinese papers indexed in the Web of Science. A list of neural regeneration studies was generated by searching the database of the Web of Science-Expanded using the term "Neural Regenera*". Inclusive criteria: (1) articles in the field of neural regeneration; (2) fundamental research on animals, clinical trials and case reports; (3) article types: article, review, proceedings paper, note, letter, editorial material, discussion, book chapter; (4) year of publication: 2003-2012; and (5) citation database: Science Citation Index-Expanded. Exclusive criteria: (1) articles requiring manual searching or with access only by telephone; (2) unpublished articles; and (3) corrections. A total of 4 893 papers were retrieved from the Web of Science published between 2003 and 2012. The papers covered 65 countries or regions, of which the United States ranked first with 1 691 papers. The most relevant papers were in the neurosciences and cell biology, and the keyword "stem cell" was the most frequent. In recent years, China showed a great increase in the number of papers. Over the entire 10 years, there were 922 Chinese papers, with Jilin University ranking first with 58 articles. Chinese papers were published in connection with many countries, including the United States, Japan, and the United Kingdom. Among the connections, the papers published by the Chinese and the American are 107, with the highest rate. With regard to funding, 689 articles were funded from various projects, occupying 74.72% of the total amount. In these projects, National Foundation and Science and Technology programs were the majority. Our bibliometric analysis provides a historical perspective on the progress of neural regeneration research. At present, the number of articles addressing neural regeneration is increasing rapidly; however, through analysis of citations it is clear that there is a long way to go to improve the academic quality.

The development and utilization of biomass energy can help to change the ways of energy production and consumption and establish a sustainable energy system that can effectively promote the development of the national economy and strengthen the protection of the environment. Here,we perform a bibliometric analysis of 9514 literature reports in the Web of Science Core Collection searched with the key words "Biomass energy" and "Environment*" date from 1998 to 2017; hot topics in the research and development of biomass energy utilization, as well as the status and development trends of biomass energy utilization and the environment, were analyzed based on content analysis and bibliometrics. The interaction between biomass energy and the environment began to become a major concern as the research progressively deepened. This work is of great significance for the development and utilization of biomass energy to put forward specific suggestions and strategies based on the analysis and demonstration of relationships and interactions between biomass energy utilization and environment. It is also useful to researchers for selecting the future research topics. Copyright © 2018 Elsevier B.V. All rights reserved.

Eigenfactor score and alternative bibliometrics surpass the impact factor in a 2-years ahead annual-citation calculation: a linear mixed design model analysis of Radiology, Nuclear Medicine and Medical Imaging journals.

2018-03-05

Because we believe the journal selection before a manuscript submission deserves further investigation in each medical specialty, we aimed to evaluate the predictive ability of seven bibliometrics in the Radiology, Nuclear Medicine and Medical Imaging category of the Web of Knowledge to calculate total citations over a 7-year period. A linear mixed effects design using random slopes and intercepts were performed on bibliometrics corresponding to 124 journals from 2007 to 2011, with their corresponding citations from 2009 to 2013, which appeared in the Journal Citations Report Science Edition. The Eigenfactor Score, Article Influence Score, Cited Half-life, 5-years impact factor and Number of Articles are significant predictors of 2-year-ahead total citations (p ≤ 0.010 for all variables). The impact factor and Immediacy Index are not significant predictors. There was a significant global effect size (R 2  = 0.934; p < 0.001), which yielded a total variance of 93.4%. Our findings support researchers' decision to stop the misuse of IF alone to evaluate journals. Radiologists and other researchers should review journal's bibliometrics for their decision-making during the manuscript submission phase. A re-ranking of journals using Eigenfactor Score, Article Influence Score, and Cited Half-life provides a better assessment of their significance and importance in particular disciplines.

To determine yearly (phase 1) and cumulative (phase 2) publication records of pharmaceutical science faculty members at research-intensive colleges and schools of pharmacy. The publication records of pharmaceutical science faculty members at research-intensive colleges and schools of pharmacy were searched on Web of Science. Fifty colleges and schools of pharmacy were randomly chosen for a search of 1,042 individual faculty members' publications per year from 2005 to 2009. A stratified random sample of 120 faculty members also was chosen, and cumulative publication counts were recorded and bibliometric indices calculated. The median number of publications per year was 2 (range, 0-34). Overall, 22% of faculty members had no publications in any given year, but the number was highly variable depending on the faculty members' colleges or schools of pharmacy. Bibliometric indices were higher for medicinal chemistry and pharmaceutics, with pharmacology ranking third and social and administrative sciences fourth. Higher bibliometric indices were also observed for institution status (ie, public vs private) and academic rank (discipline chairperson vs non-chairperson and professor vs junior faculty member) (p<0.01 for each). The median number of cumulative publications per faculty member was 34 (range, 0-370). Significant differences exist in yearly and cumulative publication rates for faculty members and bibliometric indices among pharmaceutical science disciplines and academic ranks within research-intensive colleges and schools of pharmacy. These data may be important for benchmarking purposes.

Bibliometrics: The best available information?

PubMed

Klein, Waldo C; Bloom, Martin

2005-01-01

This commentary raises significant cautions related to inherent shortcomings in the use of bibliographic analytic technology, and in particular its use in substantive decision making around promotion and tenure. Questions are raised concerning the continued use of scholarly energy for bibliometric analysis of subtly different settings. The recommendation is offered that future efforts in bibliometrics must target methods to reduce methodological shortcomings. These include clarifying the metric used to count sole/multiple authorship, and to evaluate the"merit" of manuscripts as well as journals in which they appear. Finally, the fundamental meaning of the information produced in these analyses (i.e., the validity of the measure) must be clearly presented in order for it to be credibly used.

The aim of this study was to characterize the scientific production of Italian Oral Surgery professionals by evaluating different bibliometric indices. The bibliometric evaluation was conducted on the Scopus Database upon all the Active Members joining three important Italian scientific societies in Oral Surgery (SIdCO, SIO, and SICOI). The scientific production was analysed by considering the number of total publications, number of total citations, h-index, and hc-index. Moreover, the overall sample was divided into two groups (Academics and Not Academics), according to the fact the professionals had or not a university position, and then into sub-groups according to the different career lengths. Statistical analyses were performed to compare the scientific productivity amongst groups. For all the considered parameters a lack of homogeneity between groups was reported, and significantly greater mean values were recorded for the Academics compared to the Not Academics Group. Moreover, the h-index values increased more regularly as the career length progressed than the hc-index values, even if the last seemed to be less variable. h- and hc-indices are both stable bibliometric parameters, but as the hc-index values are related not only to the number of citation but also to their age, it seems to be less influenced by the authors' career length. Bibliometric analysis of the scientific production in dentistry may facilitate the recognition of factors that may further enhance research activity and clinical performance and be useful for a comparative assessment of authors or research groups in terms of quality and quantity of the scientific production.

The use of rigorous scientific methods has contributed towards developing scientific articles of excellent methodological quality. This has made it possible to promote their citation and increase the impact factor. Brazilian periodicals have had to adapt to certain quality standards demanded by these indexing organizations, such as the content and the number of original articles published in each issue. This study aimed to evaluate the methodological adequacy of two Brazilian periodicals within the field of cardiology that are indexed in several databases and freely accessible through the Scientific Electronic Library Online (SciELO), and which are now indexed by the Web of Science (Institute for Scientific Information, ISI). Descriptive study at Brazilian Cochrane Center. All the published articles were evaluated according to merit assessment (content) and form assessment (performance). Ninety-six percent of the articles analyzed presented study designs that were adequate for answering the objectives. These two Brazilian periodicals within the field of cardiology published methodologically adequate articles, since they followed the quality standards. Thus, these periodicals can be considered both for consultation and as vehicles for publishing future articles. For further analyses, it is essential to apply other indicators of scientific activity such as bibliometrics, which evaluates quantitative aspects of the production, dissemination and use of information, and scientometrics, which is also concerned with the development of science policies, within which it is often superimposed on bibliometrics.

Purpose We aimed to investigate association between bibliometric parameters, reporting and methodological quality of vascular and endovascular surgery randomised controlled trials. Methods The most recent 75 and oldest 75 randomised controlled trials published in leading journals over a 10-year period were identified. The reporting quality was analysed using the CONSORT statement, and methodological quality with the Intercollegiate Guidelines Network checklist. We used exploratory univariate and multivariable linear regression analysis to investigate associations. Findings Bibliometric parameters such as type of journal, study design reported in title, number of pages; external funding, industry sponsoring and number of citations are associated with reporting quality. Moreover, parameters such as type of journal, subject area and study design reported in title are associated with methodological quality. Conclusions The bibliometric parameters of randomised controlled trials may be independent predictors for their reporting and methodological quality. Moreover, the reporting quality of randomised controlled trials is associated with their methodological quality and vice versa.

SU-E-I-98: PET/CT's Most-Cited 50 Articles since 2000: A Bibliometric Analysis of Classics.

PubMed

Sayed, G

2012-06-01

Despite its relatively recent introduction to clinical practice, PET/CT has gained wide acceptance both in diagnostic and therapeutic applications. Scientific publication in PET/CT has also experienced significant development since its introduction. Bibliometric analyses allow an understanding of how this publication trend has developed at an aggregated level. Citation analysis is one of the most widely used bibliometric tools of scientometrics. Analysis of classics, defined as an articles with 100 or more citations, is common in the biomedical sciences as it reflects an article's influence in its professional and scientific community. Our objective was to identify the 50 most frequently cited classic articles in PET/CT in the past 10 years. The 50 most-cited PET/CT articles were identified by searching ISI's Web of Knowledge and Pubmed databases for all related publications from 2000 through 2010. Articles were evaluated for several characteristics such as author(s), institution, country of origin, publication year, type, and number of citations. An unadjusted categorical analysis was performed to compare all articles published in the search period. The search yielded a cumulative total of 22,554 entries for the publication period, of which 15,943 were original research articles. The 50 most-cited articles were identified from the latter sum and selected out of 73 classics. The number of citations for the top 50 classics ranged from 114 to 700. PET/CT classics appeared in three general and 12 core journals. The majority of the classics were in oncologic applications of PET/CT (62%). Articles related to diagnostic topics were 6%.

Bibliometrics, the statistical analysis of written publications, is an increasingly popular approach to the assessment of scientific activity. Bibliometrics allows researchers to assess the impact of a field, or research area, and has been used to make decisions regarding research funding. Through bibliometric analysis, we hypothesized that a bibliometric analysis of difficult airway research would demonstrate a growth in authors and articles over time. Using the Web of Science (WoS) and Scopus databases, we conducted a search of published manuscripts on the difficult airway from January 1981 to December 2013. After removal of duplicates, we identified 2412 articles. We then analyzed the articles as a group to assess indicators of productivity, collaboration, and impact over this time period. We found an increase in productivity over the study period, with 37 manuscripts published between 1981 and 1990, and 1268 between 2001 and 2010 (P < .001). The difficult airway papers growth rate was bigger than that of anesthesiology research in general, with CAGR (cumulative average growth rate) since 1999 for difficult airway >9% for both WoS and Scopus, and CAGR for anesthesiology as a whole =0.64% in WoS, and =3.30% in Scopus. Furthermore, we found a positive correlation between the number of papers published per author and the number of coauthored manuscripts (P < .001). We also found an increase in the number of coauthored manuscripts, in international cooperation between institutions, and in the number of citations for each manuscript. For any author, we also identified a positive relationship between the number of citations per manuscript and the number of papers published (P < .001). We found a greater increase over time in the number of difficult airway manuscripts than for anesthesiology research overall. We found that collaboration between authors increases their impact, and that an increase in collaboration increases citation rates. Publishing in English and in certain journals, and collaborating with certain authors and institutions, increases the visibility of manuscripts published on this subject.

Identifying research lines is essential to understand the knowledge structure of a scientific domain. The aim of this study was to identify the main research topics of within the domain of public health, in the Revista Española de Saslud Pública during 2006-2015. Original articles included in the Social Sciences Citation Index (SSCI) database, available online through the Web of Science (WoS), were selected. The analysis units used were the keywords, KeyWords Plus (KW+), extracted automatically by SSCI. With KW+ obtained bibliometric, maps were created using a methodology based on the combination of co-word analysis, co-word analysis, clustering techniques and visualization techniques. We analyzed 512 documents, of which 176 KW+ were obtained with a frequency greater than or equal to 3. The results were bidimensional bibliometric maps with thematic groupings of KW+, representing the main research fronts: i) epidemiology, risk control programs disease and, in general, service organization and health policies; ii) infectious diseases, principally HIV; iii) a progressive increase in several lines interrelated with cardiovascular diseases (CVD); iv) a line multidimensional dedicated to different aspects associated to the quality of life related to health (HRQoL); and v) an emerging line linked to binge drinking. For the multidisciplinary and multidimensional nature of public health, the construction of bibliometric maps is an appropriate methodology to understand the knowledge structure of this scientific domain.

MacMaster, Frank P; Swansburg, Rose; Rittenbach, Katherine

2017-08-01

Bibliometrics play an increasingly critical role in the assessment of faculty for promotion and merit increases. Bibliometrics is the statistical analysis of publications, aimed at evaluating their impact. The objective of this study is to describe h-index and citation benchmarks in academic psychiatry. Faculty lists were acquired from online resources for all academic departments of psychiatry listed as having residency training programs in Canada (as of June 2016). Potential authors were then searched on Web of Science (Thomson Reuters) for their corresponding h-index and total number of citations. The sample included 1683 faculty members in academic psychiatry departments. Restricted to those with a rank of assistant, associate, or full professor resulted in 1601 faculty members (assistant = 911, associate = 387, full = 303). h-index and total citations differed significantly by academic rank. Both were highest in the full professor rank, followed by associate, then assistant. The range in each, however, was large. This study provides the initial benchmarks for the h-index and total citations in academic psychiatry. Regardless of any controversies or criticisms of bibliometrics, they are increasingly influencing promotion, merit increases, and grant support. As such, benchmarking by specialties is needed in order to provide needed context.

In recent years, bibliometric science has been frequently applied in the development and evaluation of scientific research. This work presents a bibliometric analysis for the research work performed in the field of geodesy "science of the measurement and mapping of the earth surface including its external gravity field". The objective of this work is to present a complete overview of the generated research on this field to assemble and study the most important publications occurred during the past seven years. The analysis was performed including the SCOPUS and WEB OF SCIENCE databases for all the geodetic scientific articles published between 2000 and 2006. The search profile was designed considering a strategy to seek for titles and article descriptors using the terms geodesy and geodetic and some other terms associated with the topics: geodetic surfaces, vertical measurements, reference systems and frames, modern space-geodetic techniques and satellite missions. Some preliminary results had been achieved specifically Bradford law of distribution for journals and education institutes, and Lotka's law for authors that also includes the cooperation between countries in terms of writing together scientific articles. In the particular case of distributions, the model suggested by Egghe (2002) was adopted for determining the cores.

The aim of this study was to examine the publication characteristics and development of Journal of Advanced Nursing during its 40-year history. Bibliometric studies of single journals have been performed, but to the best of our knowledge, bibliometric analysis and bibliometric mapping have not yet been used to analyse the literature production of the Journal of Advanced Nursing. Using descriptive bibliometrics, we studied the dynamics and trend patterns of literature production and identified document types and the most prolific authors, papers, institutions and countries. Bibliometric mapping was used to visualize the content of published articles and determine the most prolific research terms and themes published in Journal of Advanced Nursing and their evolution through time. We were also interested in determining whether there were any 'Sleeping Beauties' among the articles published in the journal. The study revealed a positive trend in literature production, although recently, the number of articles published in Journal of Advanced Nursing has slightly decreased. The most productive institutions are from the United Kingdom, which ranks in the highest place in terms of successful publishing in the journal. Thematic analysis showed that the most prolific themes corresponded to the basic aims and scope of the journal. Journal of Advanced Nursing contributes to advances in nursing research, practice and education as well as the quality of health care, teamwork and family care, with an emphasis on knowledge transfer and partnership between various healthcare professionals. © 2017 John Wiley & Sons Ltd.

The JID is a major resource for publishing dermatologic research. Here we document bibliometric systems that permit detailed analysis of JID’s relative scientific quality. We provide an overview of metrics employed by ISI Thomson Reuters Web of Knowledge and Elsevier’s open-access Scopus to measure JID’s comparative performance. We list JID’s 50 most cited articles between 1986 and 2010 and summarize the six most cited papers published during this period. We conclude by showing how selected cited papers have influenced research in the JID subcategories of immunology/infection and photobiology during this period. JID has thrived as the strength of its editorial leadership and the quality of dermatologic science have grown apace. PMID:22330274

Although bibliometric analysis affords significant insight into the progression and distribution of information within a particular research field, detailed longitudinal studies of this type are rare within the field of nursing. This study aimed to investigate, from a bibliometric perspective, the progression and trends of core international nursing journals over the longest possible time period. A detailed bibliometric analysis was undertaken among 7 core international nursing periodicals using custom historical data sourced from the Thomson Reuters Journal Citation Reports®. In the 32 years between 1977 and 2008, the number of citations received by these 7 journals increased over 700%. A sustained and statistically significant (p<0.001) 3-fold increase was also observed in the average impact factor score during this period. Statistical analysis revealed that all periodicals experienced significant (p<0.001) improvements in their impact factors over time, with gains ranging from approximately 2- to 78-fold. Overall, this study provides one of the most comprehensive, longitudinal bibliometric analyses ever conducted in the field of nursing. Impressive and continual impact factor gains suggest that published nursing research is being increasingly seen, heard and cited in the international academic community.

2015-01-01

To explore the scientific output on transsexuality in the Spanish biomedical literature between 1973 and 2011, through bibliometric and content analyses. We carried out a descriptive, cross-sectional study of Spanish biomedical articles on transsexuality published between 1973 and 2011. The data sources consisted of Índice Médico Español and ISOC-Ciencias Sociales y Humanidades. Bibliometric and content analyses were performed. A total of 65 papers were analyzed. Knowledge on transsexuality in Spain began to appear in medical journals between 1973 and 1984. A decade of intense productivity began in 1996 and the number of journals publishing articles on transsexuality multiplied in the following years. Until 2006, the year with the most biomedical productivity, biomedical discourses reproduced representations of transsexuality anchored in biological determinism. From 2008-2011, professionals writing on the topic incorporated feminist theories and social perspectives in their discourses. In the last quarter of the twentieth century, the dominant medical discourse considered manifestations of transsexual people from a biologist perspective that conceives transsexuality as a configuration mismatch between sex and gender. The emergence of new identity categories and medical reflection from non-essentialist and non-normative gender perspectives has improved the clinical management of transsexuality.

In this paper, the results of a bibliometric and visual analysis of geo-ontology research articles collected from the Web of Science (WOS) database between 1999 and 2014 are presented. The numbers of national institutions and published papers are visualized and a global research heat map is drawn, illustrating an overview of global geo-ontology research. In addition, we present a chord diagram of countries and perform a visual cluster analysis of a knowledge co-citation network of references, disclosing potential academic communities and identifying key points, main research areas, and future research trends. The International Journal of Geographical Information Science, Progress in Human Geography, and Computers & Geosciences are the most active journals. The USA makes the largest contributions to geo-ontology research by virtue of its highest numbers of independent and collaborative papers, and its dominance was also confirmed in the country chord diagram. The majority of institutions are in the USA, Western Europe, and Eastern Asia. Wuhan University, University of Munster, and the Chinese Academy of Sciences are notable geo-ontology institutions. Keywords such as "Semantic Web," "GIS," and "space" have attracted a great deal of attention. "Semantic granularity in ontology-driven geographic information systems, "Ontologies in support of activities in geographical space" and "A translation approach to portable ontology specifications" have the highest cited centrality. Geographical space, computer-human interaction, and ontology cognition are the three main research areas of geo-ontology. The semantic mismatch between the producers and users of ontology data as well as error propagation in interdisciplinary and cross-linguistic data reuse needs to be solved. In addition, the development of geo-ontology modeling primitives based on OWL (Web Ontology Language）and finding methods to automatically rework data in Semantic Web are needed. Furthermore, the topological relations between geographical entities still require further study.

A growing burden of gunshot injuries demands evidence-based ballistic trauma management. No comprehensive systematic overview of the current knowledge is available to date. This study aims to identify and analyze the most influential publications in the field of orthopedic ballistic trauma research. All databases available in the Thomson Reuters Web of Knowledge were searched to conduct this bibliometrical study. The most cited orthopedic ballistic trauma articles published between 1950 and 2015 were identified by use of a multi-step approach. Publications with ten citations and more were analyzed for citations, journal, authorship, geographic origin, area of research, anatomical site, study type, study category, and level of evidence. Citations of the 128 included studies ranged from 113 to 10. These were published in fifty different journals between 1953 and 2011. Most publications (n=106; 83%) originated from the USA, were retrospective (n=85; 66.4%), level IV studies (n=90; 70.3%), reported on spinal gunshot injuries (n=49; 38.33%) and were published between 1980 and 2000 (n=111; 86.7%). This bibliometric study provides the first comprehensive overview of influential publications in the field of orthopedic ballistic trauma research. More prospective studies and high-quality systematic reviews are needed. Centres with a high burden of gunshot injuries from the developing world need to share their experience in form of international publications, to provide a more comprehensive picture of the global gun-related orthopedic injury burden. bibliometric analysis: level III.

Several methods are available to evaluate and compare medical journals. The most popular is the journal Impact Factor, derived from averaging counts of citations to articles. Ingwersen adapted this method to assess the attractiveness of Web sites, defining the external Web Impact Factor (WIF) to be the number of external pages containing a link to a given Web site. This paper applies the WIF to 43 medical informatics societies' Web sites using advanced search engine queries to obtain the necessary link counts. The WIF was compared to the number of publications available in the Medline bibliographic database in medical informatics in these 43 countries. Between these two metrics, the observed Pearson correlation was 0.952 (p < 0.01) and the Spearman rank correlation was 0.548 (p < 0.01) showing in both cases a positive and strong significant correlation. The WIF of medicalm informatics society's Web site is statistically related to national productivity and discrepancies can be used to indicate countries where there are either weak medical informatics associations, or ones that do not make optimal use of the Web.

The objective of this study is to report on research production and publications on health inequalities through a bibliometric analysis covering publications from 1966 to 2014 and a content analysis of the 25 most-cited papers. A database of 49,294 references was compiled from the search engine Web of Science. The first article appears in 1966 and deals with equality and civil rights in the United States and the elimination of racial discrimination in access to medical care. By 2003, the term disparity has gained in prominence relative to the term inequality which was initially elected by the researchers. Marmot's 1991 article is one of the five papers with the largest number of citations and contributes to the central perspective of social determinants of health and the British influence on the international status of research on social inequalities of health.

Recently a new buzzword has slowly but surely emerged, namely the Internet of Things (IoT). The importance of IoT is identified worldwide both by organisations and governments and the scientific community with an incremental number of publications during the last few years. IoT in Health is one of the main pillars of this evolution, but limited research has been performed on future visions and trends. Thus, in this study we investigate the longitudinal trends of Internet of Things in Health through bibliometrics and use of text mining. Seven hundred seventy eight (778) articles were retrieved form The Web of Science database from 1998 to 2016. The publications are grouped into thirty (30) clusters based on abstract text analysis resulting into some eight (8) trends of IoT in Health. Research in this field is obviously obtaining a worldwide character with specific trends, which are worth delineating to be in favour of some areas.

(a) peer-reviewed published articles on stem cell transplantation for treating Duchenne muscular dystrophy indexed in Web of Science; (b) original research articles, reviews, meeting abstracts, proceedings papers, book chapters, editorial material, and news items; and (c) publication between 2002 and 2011. (a) articles that required manual searching or telephone access; (b) documents that were not published in the public domain; and (c) corrected papers. (1) Annual publication output; (2) distribution according to subject areas; (3) distribution according to journals; (4) distribution according to country; (5) distribution according to institution; (6) distribution according to institution in China; (7) distribution according to institution that cooperated with Chinese institutions; (8) top-cited articles from 2002 to 2006; (9) top-cited articles from 2007 to 2011. A total of 318 publications on stem cell transplantation for treating Duchenne muscular dystrophy were retrieved from Web of Science from 2002 to 2011, of which almost half derived from American authors and institutes. The number of publications has gradually increased over the past 10 years. Most papers appeared in journals with a focus on gene and molecular research, such as Molecular Therapy, Neuromuscular Disorders, and PLoS One. The 10 most-cited papers from 2002 to 2006 were mostly about different kinds of stem cell transplantation for muscle regeneration, while the 10 most-cited papers from 2007 to 2011 were mostly about new techniques of stem cell transplantation for treating Duchenne muscular dystrophy. The publications on stem cell transplantation for treating Duchenne muscular dystrophy were relatively few. It also needs more research to confirm that stem cell therapy is a reliable treatment for Duchenne muscular dystrophy.

To identify global trends in research on spinal cord injury-induced neurogenic bladder, through a bibliometric analysis using the Web of Science. We performed a bibliometric analysis of studies on spinal cord injury-induced neurogenic bladder using the Web of Science. Data retrieval was performed using key words "spinal cord injury", "spinal injury", "neurogenic bladder", "neuropathic bladder", "neurogenic lower urinary tract dysfunction", "neurogenic voiding dysfunction", "neurogenic urination disorder" and "neurogenic vesicourethral dysfunction". (a) published peer-reviewed articles on spinal cord injury-induced neurogenic bladder indexed in the Web of Science; (b) type of articles: original research articles and reviews; (c) year of publication: no limitation. (a) articles that required manual searching or telephone access; (b) Corrected papers and book chapters. (1) Annual publication output; (2) distribution according to journals; (3) distribution according to subject areas; (4) distribution according to country; (5) distribution according to institution; and (6) top cited publications. There were 646 research articles addressing spinal cord injury-induced neurogenic bladder in the Web of Science. Research on spinal cord injury-induced neurogenic bladder was found in the Science Citation Index-Expanded as of 1946. The United States, Ireland and Switzerland were the three major countries contributing to studies in spinal cord injury-induced neurogenic bladder in the 1970s. However, in the 1990s, the United States, the United Kingdom, the Netherlands, Germany and Japan published more papers on spinal cord injury-induced neurogenic bladder than Switzerland, and Ireland fell off the top ten countries list. In this century, the United States ranks first in spinal cord injury-induced neurogenic bladder studies, followed by France, the United Kingdom, Germany, Switzerland and Japan. Subject categories including urology, nephrology and clinical neurology, as well as rehabilitation, are represented in spinal cord injury-induced neurogenic bladder studies. From our analysis of the literature and research trends, we conclude that spinal cord injury-induced neurogenic bladder is a hot topic that will continue to generate considerable research interest in the future.

BACKGROUND: Facial paralysis is defined as severe or complete loss of facial muscle motor function. OBJECTIVE: The study was undertaken to explore a bibliometric approach to quantitatively assess the research on clinical treatment of facial paralysis using rehabilitation, physiotherapy and acupuncture using Web of Science from 1992 to 2011. DESIGN: Bibliometric approach. DATA RETRIEVAL: A bibliometric analysis based on the publications on Web of Science was performed using key words such as “facial paralysis”, “rehabilitation”, “physiotherapy” and “acupuncture”. INCLUSIVE CRITERIA: (1) Research articles on the clinical treatment of facial paralysis using acupuncture or physiotherapy (e.g. exercise, electro-stimulation) and other rehabilitation methods; (2) researches on human and animal fundamentals, clinical trials and case reports; (3) Article types: article, review, proceedings paper, note, letter, editorial material, discussion, book chapter. (4) Publication year: 1992–2011 inclusive. Exclusion criteria: (1) Articles on the causes and diagnosis on facial paralysis; (2) Type of articles: correction; (3) Articles from following databases: all databases related to social science and chemical databases in Web of Science. MAIN OUTCOME MEASURES: (1) Overall number of publications; (2) number of publications annually; (3) number of citations received annually; (4) top cited paper; (5) subject categories of publication; (6) the number of countries in which the article is published; (7) distribution of output in journals. RESULTS: Overall population stands at 3 543 research articles addressing the clinical treatment of facial paralysis in Web of Science during the study period. There is also a markedly increase in the number of publications on the subject “facial paralysis treatments using rehabilitation” during the first decade of the 21st century, except in 2004 and 2006 when there are perceptible drops in the number of articles published. The only other year during the study period saw such a drop is 1993. Specifically, there are 192 published articles on facial paralysis treated by rehabilitation in the past two decades, far more than the output of physiotherapy treatment. Physiotherapy treatment scored only 25 articles including acupuncture treatment, with over 80% of these written by Chinese researchers and clinicians. Ranked by regions, USA is by far the most productive country in terms of the number of publications on facial paralysis rehabilitation and physiotherapy research. Seeing from another angle, the journals that focus on otolaryngology published the most number of articles in rehabilitation and physiotherapy studies, whereas most acupuncture studies on facial paralysis were published in the alternative and complementary medicine journals. CONCLUSION: Study of facial paralysis remains an area of active investigation and innovation. Further clinical studies in humans addressing the use of growth factors or stem cells continue to successful facial nerve regeneration. PMID:25767492

Physiotherapy treatment scored only 25 articles including acupuncture treatment, with over 80% of these written by Chinese researchers and clinicians. Ranked by regions, USA is by far the most productive country in terms of the number of publications on facial paralysis rehabilitation and physiotherapy research. Seeing from another angle, the journals that focus on otolaryngology published the most number of articles in rehabilitation and physiotherapy studies, whereas most acupuncture studies on facial paralysis were published in the alternative and complementary medicine journals. Study of facial paralysis remains an area of active investigation and innovation. Further clinical studies in humans addressing the use of growth factors or stem cells continue to successful facial nerve regeneration.

Bibliometric analysis is a research method used in library and information science to evaluate research performance. It applies quantitative and statistical analyses to describe patterns observed in a set of publications and can help identify previous, current, and future research trends or focus. To better guide our institutional strategic plan in cancer population science, we conducted bibliometric analysis on publications of investigators currently funded by either Division of Cancer Preventions (DCP) or Division of Cancer Control and Population Science (DCCPS) at National Cancer Institute. We applied two topic modeling techniques: author topic modeling (AT) and dynamic topic modeling (DTM). Our initial results show that AT can address reasonably the issues related to investigators' research interests, research topic distributions and popularities. In compensation, DTM can address the evolving trend of each topic by displaying the proportion changes of key words, which is consistent with the changes of MeSH headings.

The objective is to automatically identify trends in Fetal Medicine over the past 10 years through a bibliometric analysis of articles published in Prenatal Diagnosis, using text mining techniques. We processed 2,423 full-text articles published in Prenatal Diagnosis between 2006 and 2015. We extracted salient terms, calculated their frequencies over time, and established evolution profiles for terms, from which we derived falling, stable, and rising trends. We identified 618 terms with a falling trend, 2,142 stable terms, and 839 terms with a rising trend. Terms with increasing frequencies include those related to statistics and medical study design. The most recent of these terms reflect the new opportunities of next- generation sequencing. Many terms related to cytogenetics exhibit a falling trend. A bibliometric analysis based on text mining effectively supports identification of trends over time. This scalable approach is complementary to analyses based on metadata or expert opinion.

The overall aim of the present study was to compare the coverage of existing research funding information for articles indexed in Scopus, Web of Science, and PubMed databases. The numbers of articles with funding information published in 2015 were identified in the three selected databases and compared using bibliometric analysis of a sample of twenty-eight prestigious medical journals. Frequency analysis of the number of articles with funding information showed statistically significant differences between Scopus, Web of Science, and PubMed databases. The largest proportion of articles with funding information was found in Web of Science (29.0%), followed by PubMed (14.6%) and Scopus (7.7%). The results show that coverage of funding information differs significantly among Scopus, Web of Science, and PubMed databases in a sample of the same medical journals. Moreover, we found that, currently, funding data in PubMed is more difficult to obtain and analyze compared with that in the other two databases.

Reducing nutrition-related health problems in Arab countries requires an understanding of the performance of Arab countries in the field of nutrition and dietetics research. Assessment of research activity from a particular country or region could be achieved through bibliometric analysis. This study was carried out to investigate research activity in "nutrition and dietetics" in Arab countries. Original and review articles published from Arab countries in "nutrition and dietetics" Web of Science category up until 2012 were retrieved and analyzed using the ISI Web of Science database. The total number of documents published in "nutrition and dietetics" category from Arab countries was 2062. This constitutes 1% of worldwide research activity in the field. Annual research productivity showed a significant increase after 2005. Approximately 60% of published documents originated from three Arab countries, particularly Egypt, Kingdom of Saudi Arabia, and Tunisia. However, Kuwait has the highest research productivity per million inhabitants. Main research areas of published documents were in "Food Science/Technology" and "Chemistry" which constituted 75% of published documents compared with 25% for worldwide documents in nutrition and dietetics. A total of 329 (15.96%) nutrition - related diabetes or obesity or cancer documents were published from Arab countries compared with 21% for worldwide published documents. Interest in nutrition and dietetics research is relatively recent in Arab countries. Focus of nutrition research is mainly toward food technology and chemistry with lesser activity toward nutrition-related health research. International cooperation in nutrition research will definitely help Arab researchers in implementing nutrition research that will lead to better national policies regarding nutrition.

According to the data of CAJCCR in 2002 to 2007 and Chinese Citation Database in 2001 to 2007. The impact factor (IF), non-self-citing impact factor, total cited frequency, cited articles, immediacy index, rate of fund papers, web immediacy download rate, average value of h index were analysed and the non-self-citing rate, h(2)/n, high cited articles were calculated. In addition, the results of cited by cole databases at home and abroad. The average value of IF and cited frequency of 13 kinds of ophthalmological periodicals were 0.3940 and 657 respectively in 2001 to 2006, which were higher than that of D part of CAJCCR. The periodicals which the five indexes of IF, non-self-citing impact factor, total cited frequency, the non-self-citing rate, immediacy index, rate of fund papers, web immediacy download rate, average value of h index and h(2)/n, high cited articles were Top 5 and cited by five or more than five kinds of the cole databases at home and abroad were Chinese Journal of Ophthalmology, Chinese Journal of Ocular Fundus Diseases, Practical Chinese Journal of Ophthalmology and Chinese Journal of Optometry & Ophthalmology. Most of indexes of Chinese Journal of Ophthalmology were the first. There are big difference between the 13 kinds of ophthalmological periodicals. The qualities of some ophthalmological periodicals should be improved.

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

Casey, Máire-Caitlín; Kerin, Michael J.

2015-01-01

Background. Every new scientific field can be traced back to a single, seminal publication. Therefore, a bibliometric analysis can yield significant insights into the history and potential future of a research field. This year marks 21 years since that first ground-breaking microRNA (miRNA) publication. Here, we make the case that the miRNA field is mature, utilising bibliometrics. Methods. Utilising the Web of Science™ (WoS) database publication and citation information, we charted the history of miRNA-related publications, describing and dissecting contributions by publication type (plus category, pay-per-view or open access), journal (highlighting dominant journals), by country, citations and languages. Results. We found that the United States of America (USA) publishes the most miRNA papers, followed by China and Germany. Significantly, publications attributed to the USA also receive the most citations per publication, followed by a close grouping of England, Germany and France. We also describe the relevance and acceptance of the miRNA field to different research areas, through its uptake in areas from oncology to plant sciences. Exploring the recent momentous change in publishing, we find that although pay-per view articles vastly out-number open-access articles, the citation rate of pay-per-view articles is currently less than double that of open-access. Conclusions. We believe the trends described here represent the typical evolution of a research field. By analysing publications, citations and distribution patterns, key moments in the evolution of this research area are recognised, indicating the maturation of the miRNA field and providing guidance for future research endeavours.

Researchers are increasingly using on line social networks to promote their work. Some authors have suggested that measuring social media activity can predict the impact of a primary study (i.e., whether or not an article will be highly cited). However, the influence of variables such as scientific quality, research disclosures, and journal characteristics on systematic reviews and meta-analyses has not yet been assessed. The present study aims to describe the effect of complex interactions between bibliometric factors and social media activity on the impact of systematic reviews and meta-analyses about psoriasis (PROSPERO 2016: CRD42016053181). Methodological quality was assessed using the Assessing the Methodological Quality of Systematic Reviews (AMSTAR) tool. Altmetrics, which consider Twitter, Facebook, and Google+ mention counts as well as Mendeley and SCOPUS readers, and corresponding article citation counts from Google Scholar were obtained for each article. Metadata and journal-related bibliometric indices were also obtained. One-hundred and sixty-four reviews with available altmetrics information were included in the final multifactorial analysis, which showed that social media and impact factor have less effect than Mendeley and SCOPUS readers on the number of cites that appear in Google Scholar. Although a journal's impact factor predicted the number of tweets (OR, 1.202; 95% CI, 1.087-1.049), the years of publication and the number of Mendeley readers predicted the number of citations in Google Scholar (OR, 1.033; 95% CI, 1.018-1.329). Finally, methodological quality was related neither with bibliometric influence nor social media activity for systematic reviews. In conclusion, there seems to be a lack of connectivity between scientific quality, social media activity, and article usage, thus predicting scientific success based on these variables may be inappropriate in the particular case of systematic reviews.

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

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

2016-01-01

We aimed to analyze the global scientific output of regulatory T-cell (Treg) research and built a model to qualitatively and quantitatively evaluate publications from 2000 to 2015. Data were obtained from the Web of Science Core Collection (WoSCC) of Thomson Reuters on January 1, 2016. The bibliometric method and Citespace III were used to analyze authors, journals, publication outputs, institutions, countries, research areas, research hotspots, and trends. In total, we identified 35,741 publications on Treg research from 2000 to 2015, and observed that the annual publication rate increased with time. The Journal of Immunology published the highest number of articles, the leading country was the USA, and the leading institute was Harvard University. Sakaguchi, Hori, Fontenot, and Wang were the top authors in Treg research. Immunology accounted for the highest number of publications, followed by oncology, experimental medicine, cell biology, and hematology. Keyword analysis indicated that autoimmunity, inflammation, cytokine, gene expression, foxp3, and immunotherapy were the research hotspots, whereas autoimmune inflammation, gene therapy, granzyme B, RORγt, and th17 were the frontiers of Treg research. This bibliometric analysis revealed that Treg-related studies are still research hotspots, and that Treg-related clinical therapies are the research frontiers; however, further study and collaborations are needed worldwide. Overall, our findings provide valuable information for the editors of immunology journals to identify new perspectives and shape future research directions. PMID:27611317

In the absence of a governance framework for climate engineering technologies such as solar radiation management (SRM), the practices of scientific research and intellectual property acquisition can de facto shape the development of the field. It is therefore important to make visible emerging patterns of research and patenting, which we suggest can effectively be done using bibliometric methods. We explore the challenges in defining the boundary of climate engineering, and set out the research strategy taken in this study. A dataset of 825 scientific publications on climate engineering between 1971 and 2013 was identified, including 193 on SRM; these are analysed in terms of trends, institutions, authors and funders. For our patent dataset, we identified 143 first filings directly or indirectly related to climate engineering technologies—of which 28 were related to SRM technologies—linked to 910 family members. We analyse the main patterns discerned in patent trends, applicants and inventors. We compare our own findings with those of an earlier bibliometric study of climate engineering, and show how our method is consistent with the need for transparency and repeatability, and the need to adjust the method as the field develops. We conclude that bibliometric monitoring techniques can play an important role in the anticipatory governance of climate engineering. PMID:25404683

Autoimmunology is a super-specialty of immunology specifically dealing with autoimmune disorders. To assess the extant literature concerning autoimmune disorders, bibliometric and scientometric analyses (namely, research topics/keywords co-occurrence, journal co-citation, citations, and scientific output trends - both crude and normalized, authors network, leading authors, countries, and organizations analysis) were carried out using open-source software, namely, VOSviewer and SciCurve. A corpus of 169,519 articles containing the keyword "autoimmunity" was utilized, selecting PubMed/MEDLINE as bibliographic thesaurus. Journals specifically devoted to autoimmune disorders were six and covered approximately 4.15% of the entire scientific production. Compared with all the corpus (from 1946 on), these specialized journals have been established relatively few decades ago. Top countries were the United States, Japan, Germany, United Kingdom, Italy, China, France, Canada, Australia, and Israel. Trending topics are represented by the role of microRNAs (miRNAs) in the ethiopathogenesis of autoimmune disorders, contributions of genetics and of epigenetic modifications, role of vitamins, management during pregnancy and the impact of gender. New subsets of immune cells have been extensively investigated, with a focus on interleukin production and release and on Th17 cells. Autoimmunology is emerging as a new discipline within immunology, with its own bibliometric properties, an identified scientific community and specifically devoted journals.

A bibliometric analysis based on the Science Citation Index Expanded from the Web of Science was carried out to provide insights into research activities and tendencies of the global drinking water from 1992 to 2011. Study emphases included performance of publication covering annual outputs, mainstream journals, Web of Science categories, leading countries, institutions, research tendencies and hotspots. The results indicated that annual output of the related scientific articles increased steadily. Water Research, Environmental Science & Technology, and Journal American Water Works Association were the three most common journals in drinking water research. The USA took a leading position out of 168 countries/territories, followed by Japan and Germany. A summary of the most frequently used keywords obtained from words in paper title analysis, author keyword analysis and KeyWords Plus analysis provided the clues to discover the current research emphases. The mainstream research related to drinking water was water treatment methods and the related contaminants. Disinfection process and consequent disinfection by-products attracted much attention. Ozonation and chlorination in disinfection, and adsorption were common techniques and are getting popular. Commonly researched drinking water contaminants concerned arsenic, nitrate, fluoride, lead, and cadmium, and pharmaceuticals emerged as the frequently studied contaminants in recent years. Disease caused by contaminants strongly promoted the development of related research. Copyright © 2012 Elsevier B.V. All rights reserved.

Environmental psychology is an interdisciplinary field that focuses on the interplay between individuals and their built and natural environments. Great progress has been made in the areas of environmental psychology by researchers form many countries. However, a thorough quantitative analysis to the emergent research trends and topics has not been found. To reveal the research characteristics and status on Environmental Psychology, 853 related papers from Web of Science core collection were analysed by CiteSpace II. The results show that: (1) the domain of Environmental Psychology was started in 1960s and showed a low growth over the past half century, which reaches a historical peak in 2017. Gifford, USA and the Journal of Environmental Psychology top the list of contributing authors, country and publication respectively. (2) "Environmental Psychology" is the most frequently keywords and has the longest span of the bursts. "ambient scent", "recycling", "children as outsiders" and "ambient temperature" are the top four largest clusters, which are the popular research topics in the domain of environmental psychology.

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

Capturing citation activity in three health sciences departments: a comparison study of Scopus and Web of Science.

Sarkozy, Alexandra; Slyman, Alison; Wu, Wendy

2015-01-01

Scopus and Web of Science are the two major citation databases that collect and disseminate bibliometric statistics about research articles, journals, institutions, and individual authors. Liaison librarians are now regularly called upon to utilize these databases to assist faculty in finding citation activity on their published works for tenure and promotion, grant applications, and more. But questions about the accuracy, scope, and coverage of these tools deserve closer scrutiny. Discrepancies in citation capture led to a systematic study on how Scopus and Web of Science compared in a real-life situation encountered by liaisons: comparing three different disciplines at a medical school and nursing program. How many articles would each database retrieve for each faculty member using the author-searching tools provided? How many cited references for each faculty member would each tool generate? Results demonstrated troubling differences in publication and citation activity capture between Scopus and Web of Science. Implications for librarians are discussed.

The purpose of this study was to identify the 100 top-cited articles in the radiology of trauma, analyze the resulting database to understand factors resulting in highly cited works, and establish trends in trauma imaging. An initial database was created via a Web of Science (WOS) search of all scientific journals using the search terms "trauma" and either "radiology" or a diagnostic modality. Articles were ranked by citation count and screened by two attending radiologists plus a tiebreaker for appropriateness. The following information was collected from each article: WOS all database citations, year, journal, authors, department affiliation, study type and design, sample size, imaging modality, subspecialty, organ, and topic. Citations for the top 100 articles ranged from 82-252, and citations per year ranged from 2.6-37.2. A plurality of articles were published in the 1990s (n = 45) and 1980s (n = 31). Articles were published across 24 journals, most commonly Radiology (n = 31) and Journal of Trauma-Injury, Infection, and Critical Care (n = 28). Articles had an average of five authors and 35 % of first authors were affiliated with a department other than radiology. Forty-six articles had sample sizes of 100 or fewer. Computed tomography (CT) was the most common modality (n = 67), followed by magnetic resonance (MR; n = 22), and X-ray (XR; n = 11). Neuroradiology (n = 48) and abdominal radiology (n = 36) were the most common subspecialties. The 100 top-cited articles in the radiology of trauma are diverse. Subspecialty bibliometric analyses identify the most influential articles of a particular field, providing more implications to clinical radiologists, trainees, researchers, editors, and reviewers than radiology-wide lists.

Bibliometric tools can be used to identify the authors, topics and research institutions that have made the greatest impact in a field of medicine. The aim of this research was to analyse military trauma publications over the last 16 years of armed conflict in order to highlight the most important lessons that have translated into civilian practice and military doctrine as well as identify emerging areas of importance. A systematic search of research published between January 2000 and December 2016 was conducted using the Thompson Reuters Web of Science database. Both primary evidence and review publications were included. Results were categorised according to relevance and topic and the 30 most cited publications were reviewed in full. The h-index, impact factors, citation counts and citation analysis were used to evaluate results. A plateau in the number of annual publications on military trauma was found, as was a shift away from publications on wound and mortality epidemiology to publications on traumatic brain injury (TBI), neurosurgery or blast injury to the head. Extensive collaboration networks exist between highly contributing authors and institutions, but less collaboration between authors from different countries. The USA produced the majority of recent publications, followed by the UK, Germany and Israel. In recent years, the number of publications on TBI, neurosurgery or blast injury to the head has increased. It is likely that the lessons of recent conflicts will continue to influence civilian medical practice, particularly regarding the long-term effects of blast-related TBI. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

To identify global research trends of stem cell transplantation for treating Parkinson's disease using a bibliometric analysis of the Web of Science. We performed a bibliometric analysis of data retrievals for stem cell transplantation for treating Parkinson's disease from 2002 to 2011 using the Web of Science. (a) peer-reviewed articles on stem cell transplantation for treating Parkinson's disease which were published and indexed in the Web of Science; (b) type of articles: original research articles, reviews, meeting abstracts, proceedings papers, book chapters, editorial material and news items; (c) year of publication: 2002-2011. (a) articles that required manual searching or telephone access; (b) we excluded documents that were not published in the public domain; (c) we excluded a number of corrected papers from the total number of articles. (1) Type of literature; (2) annual publication output; (3) distribution according to journals; (4) distribution according to subject areas; (5) distribution according to country; (6) distribution according to institution; (7) comparison of countries that published the most papers on stem cell transplantation from different cell sources for treating Parkinson's disease; (8) comparison of institutions that published the most papers on stem cell transplantation from different cell sources for treating Parkinson's disease in the Web of Science from 2002 to 2011; (9) comparison of studies on stem cell transplantation from different cell sources for treating Parkinson's disease. In total, 1 062 studies on stem cell transplantation for treating Parkinson's disease appeared in the Web of Science from 2002 to 2011, almost one third of which were from American authors and institutes. The number of studies on stem cell transplantation for treating Parkinson's disease had gradually increased over the past 10 years. Papers on stem cell transplantation for treating Parkinson's disease appeared in journals such as Stem Cells and Experimental Neurology. Although the United States published more articles addressing neural stem cell and embryonic stem cell transplantation for treating Parkinson's disease, China ranked first for articles published on bone marrow mesenchymal stem cell transplantation for treating Parkinson's disease. From our analysis of the literature and research trends, we found that stem cell transplantation for treating Parkinson's disease may offer further benefits in regenerative medicine.

There is a paucity of information about the oral and maxillofacial cytology-related articles published in a cytology journal. Journal of Cytology (JOC) is the official publication of Indian Academy of Cytologists. This study aimed to audit the oral and maxillofacial cytology-related articles published in JOC from 2007 to 2015 over a 9-year period. Bibliometric analysis of issues of JOC from 2007 to 2015 was performed using web-based search. The articles published were analyzed for type of article and individual topic of oral and maxillofacial cytology. The articles published were also checked for authorship trends. Of the total 93 published articles related to oral and maxillofacial cytology, original articles (43) and case reports (33) contribute the major share. The highest number of oral and maxillofacial cytology-related articles was published in 2014 with 17 articles and the least published year was 2010 with three articles. Among the oral and maxillofacial cytology-related articles published in JOC, diseases of salivary gland (26) followed by oral exfoliated cells (17), soft tissue tumors (7), round cell tumors (6) and spindle cell neoplasms (5) form the major attraction of the contributors. The largest numbers of published articles related to oral and maxillofacial cytology were received from Postgraduate Institute of Medical Education and Research, Chandigarh (5), and Jawaharlal Nehru Medical College, Aligarh (5). This paper may be considered as a baseline study for the bibliometric information regarding oral and maxillofacial cytology-related articles published in India.

This study aimed at exploring the citation parameters of contact lenses articles published in the Ophthalmology thematic category of the Journal Citation Reports (JCR). The Thompson Reuters Web of Science database was accessed to record bibliometric information and citation parameters of all journals listed under the Ophthalmology area of the 2011 JCR edition, including the journals with main publication interests in the contact lens field. In addition, the same database was used to unveil all contact lens-related articles published in 2011 in the same thematic area, whereupon differences in citation parameters between those articles published in contact lens and non-contact lens-related journals were explored. Significant differences in some bibliometric indicators such as half-life and overall citation count were found between contact lens-related journals (shorter half-life and fewer citations) and the median values for the Ophthalmology thematic area of the JCR. Visual examination of all Ophthalmology journals uncovered a total of 156 contact lens-related articles, published in 28 different journals, with 27 articles each for Contact Lens & Anterior Eye, Eye & Contact Lens, and Optometry and Vision Science. Significant differences in citation parameters were encountered between those articles published in contact lens and non-contact lens source journals. These findings, which disclosed contact lenses to be a fertile area of research, may be of interest to researchers and institutions. Differences in bibliometric indicators are of relevance to avoid unwanted bias when conducting between- and within-discipline comparisons of articles, journals, and researchers.

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.

We conducted a comprehensive bibliometrics analysis to calculate the H, G, M, A and R indicators for all Iranian biomedical research centers (IBRCs) from the output of ISI Web of Science (WoS) and Scopus between 1991 and 2010. We compared the research performance of the research centers according to these indicators. This was a cross-sectional and descriptive-analytical study, conducted on 104 Iranian biomedical research centers between August and September 2011. We collected our data through Scopus and WoS. Pearson correlation coefficient between the scientometrics indicators was calculated using SPSS, version 16. The mean values of all indicators were higher in Scopus than in WoS. Drug Applied Research Center of Tabriz University of Medical Sciences had the highest number of publications in both WoS and Scopus databases. This research center along with Royan Institute received the highest number of citations in both Scopus and WoS, respectively. The highest correlation was seen between G and R (.998) in WoS and between G and R (.990) in Scopus. Furthermore, the highest overlap of the 10 top IBRCs was between G and H in WoS (100%) and between G-R (90%) and H-R (90%) in Scopus. Research centers affiliated to the top ranked Iranian medical universities obtained a better position with respect to the studied scientometrics indicators. All aforementioned indicators are important for ranking bibliometrics studies as they refer to different attributes of scientific output and citation aspects.

This study aims to make a bibliometric analysis of the studies on breast reduction (BR) between the years 1980 and 2016 and identify important studies through trend topics as well as active authors, countries, universities, scientific journals, and citation and co-citation analyses about BR. Although BR looks like one of the cosmetic surgeries performed in order to restore the woman's appearance, in fact it is a reconstructive surgery that eliminates back pain, stance disorder, headache, shoulder pain, back and cervical disk hernia, difficulty in breathing, hollowness caused by bra straps, hygiene problems under breasts (e.g., rash or fungal infections), and limitations in some daily activities. However, the related literature has little information about the publications on this issue. Bibliometric analysis was performed by downloading all the documents published between 1980 and 2016 from Thomson Reuters Web of Science (WoS; Thomson Reuters, New York, NY, USA), using the keywords including "breast reduction", "gigantomastia", "reduction mammaplasty", and "reduction mammoplasty". There was a total of 1427 publications in the WoS database. Of these publications, 869 (60.90%) were research articles. The top three research areas of these publications were surgery with 1178 (82.55%) publications, oncology with 78 (5.47%) publications, and obstetrics gynecology with 67 (4.70%) publications. The top three countries that contributed to the literature most were the USA (515), England (147), and Turkey (83), respectively; the top university that contributed most was Harvard University, and the top two authors who contributed most were Drew PJ and Iwuagwu OC (13; 0.91%). The top-cited publication was "A Simplified Vertical Reduction Mammaplasty: Shortening the Learning Curve" written by Hall-Findlay, EJ in 1999. The journals with top numbers of publications were Plastic and Reconstructive Surgery (483; 33.85%), Annals of Plastic Surgery (164; 11.50%) and Aesthetic Plastic Surgery (147; 10.30%) respectively. Despite the fact that the BR literature is contributed by developed countries, developing countries, particularly Turkey and Brazil, also had significant contributions to the literature. This journal requires that authors assign a level of evidence to each article.

Bibliometric analysis of scientific performance within a country or speciality, facilitate the recognition of factors that may further enhance research activity and performance. Our aim was to illicit the current state of Irelands orthopaedic research output in terms of quantity and quality. We performed a retrospective bibliometric analysis of all Irish orthopaedic publications over the past 5 years, in the top 20 peer-reviewed orthopaedic journals. Utilising the MEDLINE database, each journal was evaluated for articles that were published over the study period. Reviews, editorials, reports and letters were excluded. Each article abstract was analysed for research content, and country of origin. A nation's mean IF was defined by multiplying each journal's IF by the number of articles. Publications per million (PmP) was calculated by dividing the total number of publications by the population of each country. We analysed a total of 25,595 article abstracts. Ireland contributed 109 articles in total (0.42% of all articles), however ranking according to population per million was 10th worldwide. Ireland ranked 18th worldwide in relation to mean impact factor, which was 2.91 over the study period. Ireland published in 16 of the top 20 journals, 9 of these were of European origin, and 1 of the top 5 was of American origin. In total, 61 Irish articles were assignable to clinical orthopaedic units. Clinical based studies (randomised controlled trials, observational, and epidemiology/bibliometric articles) and research based studies (In vivo, In vitro, and biomechanical) numbered 76 (69.7%) and 33 (30.2%) articles, respectively. This study provides a novel overview of current Irish orthopaedic related research, and how our standards translate to the worldwide orthopaedic community. In order to maintain our publication productivity, academic research should continue to be encouraged at post graduate level.

The article presents a survey of Russian researchers' synchronous international scientific mobility as an element of the global system of scientific labor market. Synchronous international scientific mobility is a simultaneous holding of scientific positions in institutions located in different countries. The study explores bibliometric data from the Web of Science Core Collection and socio-economic indicators for 56 countries. In order to examine international scientific mobility, we use a method of affiliations. The paper introduces a model of synchronous international scientific mobility. It enables to specify country's involvement in the international division of scientific labor. Synchronous international scientific mobility is a modern form of the international division of labor in science. It encompasses various forms of part-time, temporary and remote employment of scientists. The analysis reveals the distribution of Russian authors in the space of affiliations, and directions of upward/downward international scientific mobility. The bibliometric characteristics of mobile authors are isomorphic to those of receiver country authors. Synchronous international scientific mobility of Russian authors is determined by differences in scientific impacts between receiver and donor countries.

Lemont B. Kier: a bibliometric exploration of his scientific production and its use.

PubMed

Restrepo, Guillermo; Llanos, Eugenio J; Silva, Adriana E

2013-12-01

We thought an appropriate way to celebrate the seminal contribution of Kier is to explore his influence on science, looking for the impact of his research through the citation of his scientific production. From a bibliometric approach the impact of Kier's work is addressed as an individual within a community. Reviewing data from his curriculum vitae, as well as from the ISI Web of Knowledge (ISI), his role within the scientific community is established and the way his scientific results circulate is studied. His curriculum vitae is explored emphasising the approaches he used in his research activities and the social ties with other actors of the community. The circulation of Kier's publications in the ISI is studied as a means for spreading and installing his discourse within the community. The citation patterns found not only show the usage of Kier's scientific results, but also open the possibility to identify some characteristics of this discursive community, such as a common vocabulary and common research goals. The results show an interdisciplinary research work that consolidates a scientific community on the topic of drug discovery.

To analyze the use of the h-index as a measure of the bibliometric impact of Brazilian researchers' scientific publications. The scientific production of Brazilian CNPq 1-A researchers in the areas of public health, immunology and medicine were compared. The mean h-index of the groups of researchers in each area were estimated and nonparametric Kruskal Wallis test and multiple comparisons Behrens-Fisher test were used to compare the differences. The h-index means were higher in the area of Immunology than in Public Health and Medicine when the Web of Science base was used. However, this difference disappears when the comparison is made using Scopus or Google Scholar. The emergence of Google Scholar brings a new level to discussions on the measure of the bibliometric impact of scientific publications. Areas with strong professional components, in which knowledge is produced and must also be published in the native language, vis-a-vis its dissemination to the international community, necessarily have a standard of scientific publications and citations different from areas exclusively or predominantly academic and they are best captured by Google Scholar.

The purpose of this study was to investigate the correlation between quantitative measures of academic productivity and academic rank among full-time academic plastic surgeons. Bibliometric indices were computed for all full-time academic plastic surgeons in the United States. The primary study variable was academic rank. Bibliometric predictors included the Hirsch index, I-10 index, number of publications, number of citations, and highest number of citations for a single publication. Descriptive, bivariate, and correlation analyses were computed. Multiple comparisons testing was used to calculate adjusted associations for subgroups. For all analyses, a value of p < 0.05 was considered significant. The cohort consisted of 607 plastic surgeons across 91 Accreditation Council for Graduate Medical Education-approved programs. Of them, 4.1 percent were instructors/lecturers, 43.7 percent were assistant professors, 22.1 percent were associate professors, 25.7 percent were professors, and 4.4 percent were endowed professors. Mean values were as follows: Hirsch index, 10.2 ± 9.0; I-10 index, 17.2 ± 10.2; total number of publications, 45.5 ± 69.4; total number of citations, 725.0 ± 1448.8; and highest number of citations for a single work, 117.8 ± 262.4. Correlation analyses revealed strong associations of the Hirsch index, I-10 index, number of publications, and number of citations with academic rank (rs = 0.62 to 0.64; p < 0.001). Academic rank in plastic surgery is strongly correlated with several quantitative metrics of research productivity. Although academic promotion is the result of success in multiple different areas, bibliometric measures may be useful adjuncts for assessment of research productivity.

Evaluative bibliometrics uses advanced techniques to assess the impact of scholarly work in the context of other scientific work and usually compares the relative scientific contributions of research groups or institutions. Using publications from the National Institute of Allergy and Infectious Diseases (NIAID) HIV/AIDS extramural clinical trials networks, we assessed the presence, performance, and impact of papers published in 2006–2008. Through this approach, we sought to expand traditional bibliometric analyses beyond citation counts to include normative comparisons across journals and fields, visualization of co-authorship across the networks, and assess the inclusion of publications in reviews and syntheses. Specifically, we examined the research output of the networks in terms of the a) presence of papers in the scientific journal hierarchy ranked on the basis of journal influence measures, b) performance of publications on traditional bibliometric measures, and c) impact of publications in comparisons with similar publications worldwide, adjusted for journals and fields. We also examined collaboration and interdisciplinarity across the initiative, through network analysis and modeling of co-authorship patterns. Finally, we explored the uptake of network produced publications in research reviews and syntheses. Overall, the results suggest the networks are producing highly recognized work, engaging in extensive interdisciplinary collaborations, and having an impact across several areas of HIV-related science. The strengths and limitations of the approach for evaluation and monitoring research initiatives are discussed. PMID:21394198

Bibliometric indicators and analyses of clinical research articles can help to quantify the scientific production of hospitals and institutions and identify their main areas of research. The aim of this study was to draw up a bibliometric map of clinical research in dermatology by Spanish hospitals and institutions through an analysis of quantitative, qualitative, and topic-based variables. Bibliometric study of clinical research articles that met the inclusion criteria and had a definitive publication date between 2005 and 2014 in PubMed or Embase in which the corresponding author's affiliation was a Spanish dermatology department or institution. Barcelona and Madrid were the provinces with the highest number of articles and citations. The centers with the most articles and citations were Hospital Clínic and Instituto Valenciano de Oncología. Those 2 hospitals also produced the highest number of articles on the most common research topic identified: melanoma. Because the articles were selected on the basis of the affiliation of the corresponding author to a Spanish dermatology center, this analysis does not include collaborative studies or clinical research studies led by nondermatology centers. We have created a bibliometric map of clinical dermatology research in Spain that shows the distribution of scientific production and the main areas of research by province and hospital/institution. This map could be useful for education and research purposes. Copyright © 2017 AEDV. Publicado por Elsevier España, S.L.U. All rights reserved.

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.

Quantitative data are lacking on the profile of published research in aromatherapy. The objective of the study was to investigate the profile of original and review articles under the topic aromatherapy using bibliometric analysis. Articles on aromatherapy, published between 1995 and 2014, were retrieved from the Science Citation Index-Expanded database from the Web of Science. The records extracted were analyzed for citation characteristics, including the distribution of publication years, languages, countries or regions, journals, articles, and authors using HistCite 12.03.17. VOSviewer v.1.61 was used to construct bibliometric diagrams. A total of 549 original and review articles, published in 287 different peer-reviewed journals by 1888 authors, were identified. There was a steady increase in the number of published articles from 1995 to 2014. The majority of the articles was written in English (95.8%) and the United States was the leading country in the total number of published articles (n = 107, 19.5%) Journal of Alternative and Complementary Medicine published the greatest number of articles on the topic (n = 31, 5.6%). The article that received the greatest number of citations was published in Complementary Therapies in Medicine. Visualization analysis based on co-occurrences of words in the title and abstract revealed three clusters of research topics, including essential oil, intervention, and complementary medicine. This study provided a systematic overview of productivity and visibility of research work in aromatherapy and the findings could be used for organizing and prioritizing future research efforts in aromatherapy research.

Background: There is a paucity of information about the oral and maxillofacial cytology-related articles published in a cytology journal. Journal of Cytology (JOC) is the official publication of Indian Academy of Cytologists. Objective: This study aimed to audit the oral and maxillofacial cytology-related articles published in JOC from 2007 to 2015 over a 9-year period. Materials and Methods: Bibliometric analysis of issues of JOC from 2007 to 2015 was performed using web-based search. The articles published were analyzed for type of article and individual topic of oral and maxillofacial cytology. The articles published were also checked for authorship trends. Results: Of the total 93 published articles related to oral and maxillofacial cytology, original articles (43) and case reports (33) contribute the major share. The highest number of oral and maxillofacial cytology-related articles was published in 2014 with 17 articles and the least published year was 2010 with three articles. Among the oral and maxillofacial cytology-related articles published in JOC, diseases of salivary gland (26) followed by oral exfoliated cells (17), soft tissue tumors (7), round cell tumors (6) and spindle cell neoplasms (5) form the major attraction of the contributors. The largest numbers of published articles related to oral and maxillofacial cytology were received from Postgraduate Institute of Medical Education and Research, Chandigarh (5), and Jawaharlal Nehru Medical College, Aligarh (5). Conclusion: This paper may be considered as a baseline study for the bibliometric information regarding oral and maxillofacial cytology-related articles published in India. PMID:29731569

Background: We conducted a comprehensive bibliometrics analysis to calculate the H, G, M, A and R indicators for all Iranian biomedical research centers (IBRCs) from the output of ISI Web of Science (WoS) and Scopus between 1991 and 2010. We compared the research performance of the research centers according to these indicators. Methods: This was a cross-sectional and descriptive-analytical study, conducted on 104 Iranian biomedical research centers between August and September 2011. We collected our data through Scopus and WoS. Pearson correlation coefficient between the scientometrics indicators was calculated using SPSS, version 16. Results: The mean values of all indicators were higher in Scopus than in WoS. Drug Applied Research Center of Tabriz University of Medical Sciences had the highest number of publications in both WoS and Scopus databases. This research center along with Royan Institute received the highest number of citations in both Scopus and WoS, respectively. The highest correlation was seen between G and R (.998) in WoS and between G and R (.990) in Scopus. Furthermore, the highest overlap of the 10 top IBRCs was between G and H in WoS (100%) and between G-R (90%) and H-R (90%) in Scopus. Conclusion: Research centers affiliated to the top ranked Iranian medical universities obtained a better position with respect to the studied scientometrics indicators. All aforementioned indicators are important for ranking bibliometrics studies as they refer to different attributes of scientific output and citation aspects. PMID:26478875

Scholastic productivity has previously been shown to be positively associated with National Institute of Health (NIH) grants and industry funding. This study examines whether society, industry, or federal funding contributes toward academic productivity as measured by scholastic output of academic plastic surgeons. Institution Web sites were used to acquire academic attributes of full-time academic plastic surgeons. The Center for Medicare and Medicaid Services Open Payment database, NIH reporter, the Plastic Surgery Foundation (PSF), and American Association of Plastic Surgeons (AAPS) Web sites were accessed for funding and endowment details. Bibliometric data of each surgeon were then collected via Scopus to ascertain strengths of association with each source. Multiple linear regression analysis was used to identify significant contributors to high scholastic output. We identified 935 academic plastic surgeons with 94 (10.1%), 24 (2.6%), 724 (77.4%), and 62 (6.6%) receiving funding from PSF, AAPS, industry, and NIH, respectively. There were positive correlations in receiving NIH, PSF, and/or AAPS funding (P < 0.001), whereas industry funding was found to negatively associate with PSF (r = -0.75, P = 0.022) grants. The NIH R award was consistently found to be the most predictive of academic output across bibliometrics, followed by the AAPS academic scholarship award. Conventional measures of academic seniority remained predictive across all measures used. Our study demonstrates for the first time interactions between industry, federal, and association funding. The NIH R award was the strongest determinant of high scholastic productivity. Recognition through AAPS academic scholarships seemed to associate with subsequent success in NIH funding.

A bibliometric analysis. The aim of this article was to study bibliometric changes over the last 30 years of Spine. These trends are important regarding academic publication productivity. Inflation in authorship number and other bibliometric variables has been described in the scientific literature. The issue of author gender is taking on increasing importance, as efforts are being made to close the gender gap. From 1985 to 2015, 10-year incremental data for several bibliometric variables were collected, including author gender. Standard bivariate statistical analyses were performed. Trends over time were assessed by the Cochran linear trend. A P < 0.05 was considered statistically significant. Inclusion criteria were met for 1566 manuscripts. The majority of the manuscripts were from North America (51.2%), Europe (25.2%), and Asia (20.8%). The number of manuscripts, authors, countries, pages, and references all increased from 1985 to 2015. There was a slight increase in female first authors over time (17.5% to 18.4%, P = 0.048). There was no gender change over time for corresponding authors (14.3% to 14.0%, P = 0.29). There was an 88% increase in the percentage of female first authors having male corresponding authors (P = 0.00004), and a 123% increase in male first authors having female corresponding authors (P = 0.0002). The 14% to 18% of female authors in Spine is higher than the ∼5% female membership of the Scoliosis Research Society and North American Spine Society. Manuscripts in Spine over the past 30 years have shown a significant increase in the number of authors, collaborating institutions and countries, printed pages, references, and number of times each manuscript was cited. There has been a mild increase in female first authorship, but none in corresponding authorship. Increases in female authorship will likely require recruitment of more females into the discipline rather than providing females in the discipline with authorship opportunities. N/A.

Database tomography (DT) is a textual database analysis system consisting of two major components: (1) algorithms for extracting multiword phrase frequencies and phrase proximities (physical closeness of the multiword technical phrases) from any type of large textual database, to augment (2) interpretative capabilities of the expert human analyst. DT was used to derive technical intelligence from a fullerenes database derived from the Science Citation Index and the Engineering Compendex. Phrase frequency analysis by the technical domain experts provided the pervasive technical themes of the fullerenes database, and phrase proximity analysis provided the relationships among the pervasive technical themes. Bibliometric analysis of the fullerenes literature supplemented the DT results with author/journal/institution publication and citation data. Comparisons of fullerenes results with past analyses of similarly structured near-earth space, chemistry, hypersonic/supersonic flow, aircraft, and ship hydrodynamics databases are made. One important finding is that many of the normalized bibliometric distribution functions are extremely consistent across these diverse technical domains and could reasonably be expected to apply to broader chemical topics than fullerenes that span multiple structural classes. Finally, lessons learned about integrating the technical domain experts with the data mining tools are presented.

To conduct the bibliometric analysis of the Journal of the College of Physicians and Surgeons Pakistan (JCPSP) from 2012 to 2014. The prime objectives of this report were to determine the number and percentage of articles by year, authorship pattern, gender and geographical affiliation, ranking by subject and citation analysis. A data collection instrument was developed as bibliometric form. The data was analysed using the Microsoft Excel spread sheet. Editorials and letters to editors were excluded. There were 1106 total research documents, including 721 original articles and 385 case reports. A rapid increase in number of articles per year was noticed, more original papers than case reports. Majority of the authors were male. The contribution of Balochistan and Khyber Pakhtunkhwa was less than the other provinces. JCPSP was the most cited document in the reference list of the research documents. The scholars of Khyber Pakhtunkhwa and Balochistan and female researchers should give more attention in writing quality articles eligible for consideration at this Journal. It is also suggested that writers should be compelled to address such fields of medical sciences as neurology, nephrology, anatomy and pharmacology, while writing original articles and case reports.

With global spend on cancer research from the public sector now in excess of 14 billion euro, as well as the increasing burden of disease in market economies and low-middle income countries through changing demographics (ageing and population growth) cancer is now one of the most complex and global public policy issues. Using novel bibliometrics we have sought to investigate changes in research activity (total output), relative commitment and collaborations between countries/regions with similar healthcare and population and development parameters - United Kingdom, France, Germany, Canada and Sweden - to assess the utility of this policy research approach by analysing two different cohorts (1995-1999 and 2000-2004) to study the impact of changes on research publications as a surrogate for overall research activity.

Bibliometrics is defined as the study of statistical and mathematical methods used to quantitatively analyze scientific literature. The application of bibliometrics in neurosurgery is in its infancy. The authors calculate a number of publication productivity measures for almost all academic neurosurgeons and departments within the US. The h-index, g-index, m-quotient, and contemporary h-index (hc-index) were calculated for 1225 academic neurosurgeons in 99 (of 101) programs listed by the Accreditation Council for Graduate Medical Education in January 2013. Three currently available citation databases were used: Google Scholar, Scopus, and Web of Science. Bibliometric profiles were created for each surgeon. Comparisons based on academic rank (that is, chairperson, professor, associate, assistant, and instructor), sex, and subspecialties were performed. Departments were ranked based on the summation of individual faculty h-indices. Calculations were carried out from January to February 2013. The median h-index, g-index, hc-index, and m-quotient were 11, 20, 8, and 0.62, respectively. All indices demonstrated a positive relationship with increasing academic rank (p < 0.001). The median h-index was 11 for males (n = 1144) and 8 for females (n = 81). The h-index, g-index and hc-index significantly varied by sex (p < 0.001). However, when corrected for academic rank, this difference was no longer significant. There was no difference in the m-quotient by sex. Neurosurgeons with subspecialties in functional/epilepsy, peripheral nerve, radiosurgery, neuro-oncology/skull base, and vascular have the highest median h-indices; general, pediatric, and spine neurosurgeons have the lowest median h-indices. By summing the manually calculated Scopus h-indices of all individuals within a department, the top 5 programs for publication productivity are University of California, San Francisco; Barrow Neurological Institute; Johns Hopkins University; University of Pittsburgh; and University of California, Los Angeles. This study represents the most detailed publication analysis of academic neurosurgeons and their programs to date. The results for the metrics presented should be viewed as benchmarks for comparison purposes. It is our hope that organized neurosurgery will adopt and continue to refine bibliometric profiling of individuals and departments.

A bibliometric study was carried out to ascertain the volume and impact of scientific literature published on second-generation antipsychotic drugs (SGAs) in Singapore from 1997 to 2011. A search of the EMBASE and MEDLINE databases was performed to identify articles originating from Singapore that included the descriptors 'atypic* antipsychotic*', 'second-generation antipsychotic*', 'clozapine', 'risperidone', 'olanzapine', 'ziprasidone', 'quetiapine', 'sertindole', 'aripiprazole', 'paliperidone', 'amisulpride', 'zotepine', 'asenapine', 'iloperidone', 'lurasidone', 'perospirone' and 'blonanserin' in the article titles. Certain bibliometric indicators of production and dispersion (e.g. Price's Law on the increase of scientific literature, and Bradford's Law) were applied, and the participation index of various countries was calculated. The bibliometric data was also correlated with some social and health data from Singapore, such as the total per capita expenditure on health and gross domestic expenditure on research and development. From 1997 to 2011, a total of 51 articles on SGAs in Singapore were published. Our results suggested non-fulfilment of Price's Law (r = 0.0648 after exponential adjustment vs. r = 0.2140 after linear adjustment). The most widely studied drugs were clozapine (21 articles), risperidone (16 articles) and olanzapine (8 articles). Division into Bradford zones yielded a nucleus occupied by the Journal of Clinical Psychopharmacology (6 articles) and the Singapore Medical Journal(4 articles). The analysed material was published in a total of 30 journals, with the majority from six journals. Four of these six journals have an impact factor greater than 2. Publications on SGAs in Singapore are still too few to confirm an exponential growth of scientific literature.

Examining the Predictive Validity of NIH Peer Review Scores

Lindner, Mark D.; Nakamura, Richard K.

2015-01-01

The predictive validity of peer review at the National Institutes of Health (NIH) has not yet been demonstrated empirically. It might be assumed that the most efficient and expedient test of the predictive validity of NIH peer review would be an examination of the correlation between percentile scores from peer review and bibliometric indices of the publications produced from funded projects. The present study used a large dataset to examine the rationale for such a study, to determine if it would satisfy the requirements for a test of predictive validity. The results show significant restriction of range in the applications selected for funding. Furthermore, those few applications that are funded with slightly worse peer review scores are not selected at random or representative of other applications in the same range. The funding institutes also negotiate with applicants to address issues identified during peer review. Therefore, the peer review scores assigned to the submitted applications, especially for those few funded applications with slightly worse peer review scores, do not reflect the changed and improved projects that are eventually funded. In addition, citation metrics by themselves are not valid or appropriate measures of scientific impact. The use of bibliometric indices on their own to measure scientific impact would likely increase the inefficiencies and problems with replicability already largely attributed to the current over-emphasis on bibliometric indices. Therefore, retrospective analyses of the correlation between percentile scores from peer review and bibliometric indices of the publications resulting from funded grant applications are not valid tests of the predictive validity of peer review at the NIH.

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

To evaluate by bibliometric and thematic analysis the scientific literature on omega-3 fatty acids indexed in international databases on health sciences and to establish a comparative base for future analysis. Searches were conducted with the descriptor (MeSH, as Major Topic) "Fatty Acids, Omega-3" from the first date available until December 31, 2010. Databases consulted: MEDLINE (via PubMed), EMBASE, ISI Web of Knowledge, CINAHL and LILACS. The most common type of document was originals articles. Obsolescence was set at 5 years. The geographical distribution of authors who appear as first author was EEUU and the articles were written predominantly in English. The study population was 90.98% (95% CI 89.25 to 92.71) adult humans. The documents were classified into 59 subject areas and the most studied topic 16.24% (95% CI 14.4 to 18.04) associated with omega-3, was cardiovascular disease. This study indicates that the scientific literature on omega-3 fatty acids is a full force area of knowledge. The Anglo-Saxon institutions dominate the scientific production and it is mainly oriented to the study of cardiovascular disease.

Despite the current global trend of reduction in the morbidity and mortality of neglected diseases, dengue's incidence has increased and occurrence areas have expanded. Dengue also persists as a scientific and technological challenge since there is no effective treatment, vaccine, vector control or public health intervention. Combining bibliometrics and social network analysis methods can support the mapping of dengue research and development (R&D) activities worldwide. The aim of this paper is to map the scientific scenario related to dengue research worldwide. We use scientific publication data from Web of Science Core Collection - articles indexed in Science Citation Index Expanded (SCI-EXPANDED) - and combine bibliometrics and social network analysis techniques to identify the most relevant journals, scientific references, research areas, countries and research organisations in the dengue scientific landscape. Our results show a significant increase of dengue publications over time; tropical medicine and virology as the most frequent research areas and biochemistry and molecular biology as the most central area in the network; USA and Brazil as the most productive countries; and Mahidol University and Fundação Oswaldo Cruz as the main research organisations and the Centres for Disease Control and Prevention as the most central organisation in the collaboration network. Our findings can be used to strengthen a global knowledge platform guiding policy, planning and funding decisions as well as to providing directions to researchers and institutions. So that, by offering to the scientific community, policy makers and public health practitioners a mapping of the dengue scientific landscape, this paper has aimed to contribute to upcoming debates, decision-making and planning on dengue R&D and public health strategies worldwide.

Quantitative, qualitative, and innovative application of bibliometric research performance indicators to anatomy and radiology research and education can enhance cross-fertilization between the two disciplines. We aim to use these indicators to identify long-term trends in dissemination of publications in neuroimaging anatomy (including both productivity and citation rates), which has subjectively waned in prestige during recent years. We examined publications over the last 40 years in two neuroradiological journals, AJNR and Neuroradiology, and selected and categorized all neuroimaging anatomy research articles according to theme and type. We studied trends in their citation activity over time, and mathematically analyzed these trends for 1977, 1987, and 1997 publications. We created a novel metric, "citation half-life at 10 years postpublication" (CHL-10), and used this to examine trends in the skew of citation numbers for anatomy articles each year. We identified 367 anatomy articles amongst a total of 18,110 in these journals: 74.2% were original articles, with study of normal anatomy being the commonest theme (46.7%). We recorded a mean of 18.03 citations for each anatomy article, 35% higher than for general neuroradiology articles. Graphs summarizing the rise (upslope) in citation rates after publication revealed similar trends spanning two decades. CHL-10 trends demonstrated that more recently published anatomy articles were likely to take longer to reach peak citation rate. Bibliometric analysis suggests that anatomical research in neuroradiology is not languishing. This novel analytical approach can be applied to other aspects of neuroimaging research, and within other subspecialties in radiology and anatomy, and also to foster anatomical education. © 2014 Wiley Periodicals, Inc.

Breast cancer is the most common form of cancer among women, with an estimated 194,280 new cases diagnosed in the United States in 2009 alone. The primary aim of this work was to provide an in-depth evaluation of research yield in breast cancer from 1945 to 2008, using large-scale data analysis, the employment of bibliometric indicators of production and quality, and density-equalizing mapping. Data were retrieved from the Web of Science (WOS) Science Citation Expanded database; this was searched using the Boolean operator, 'OR', with different terms related to breast cancer, including "breast cancer", "mammary ductal carcinoma" and "breast tumour". Data were then extracted from each file, transferred to Excel charts and visualised as diagrams. Mapping was performed as described by Groneberg-Kloft et al. in 2008. A total of 180,126 breast cancer-associated items were produced over the study period; these had been cited 4,136,224 times. The United States returned the greatest level of output (n = 77,101), followed by the UK (n = 18,357) and Germany (n = 12,529). International cooperation peaked in 2008, with 3,127 entries produced as a result; relationships between the United States and other countries formed the basis for the 10 most common forms of bilateral cooperation. Publications from nations with high levels of international cooperation were associated with greater average citation rates. A total of 4,096 journals published at least one item on breast cancer, although the top 50 most prolific titles together accounted for over 43% (77,517/180,126) of the total output. Breast cancer-associated research output continues to increase annually. In an era when bibliometric indicators are increasingly being employed in performance assessment, these findings should provide useful information for those tasked with improving that performance.

Objectives The aim of this study is to compare the quantity and quality of scientific publications in transplantation fields that were written by researchers from Mainland China, Japan, South Korea and Taiwan in the East Asia region. Settings East Asia. Participants and outcome measures Articles except editorials, conference abstracts, letters, news and corrections published in 25 transplantation journals from 2006 to 2015 were screened with the Web of Science database. The number of total and annual articles, article types (study design and transplantation site), impact factor, citations and articles in the high-impact journals was determined to assess the quantity and quality of transplantation research from East Asia. The correlation of socioeconomic factors and annual publications was also analysed. Results From 2006 to 2015, there were 47 141 articles published in transplantation journals, of which researchers from Japan published 3694 articles, followed by Mainland China, South Korea and Taiwan with 2778, 1643 and 951 articles, respectively. Similar trends were observed in accumulated impact factor, accumulated citations, articles in the high-impact journals and articles on transplantation site. Publications from Japan had the highest average impact factor and citation, while those from Mainland China had the lowest. Additionally, in terms of study design, authors from Mainland China contributed to most clinical trials and randomised controlled trials, but authors from Japan contributed to most case reports. The annual numbers of articles from Mainland China and South Korea increased linearly (p<0.05), but those from Japan and Taiwan remained stable for the period studied. The annual numbers of articles from Mainland China and South Korea were positively correlated with gross domestic product (p<0.05). Conclusions Transplantation research productivity in East Asia is highly skewed, with gross domestic product having a significant positive correlation. Mainland China still lags far behind Japan in most bibliometric indicators; thus, there is vast room for improvement. PMID:27489154

The number of citations a scientific article receives provides a good indication of its impact within any given field. This bibliometric analysis aimed to identify the 100 most cited articles in Emergency Abdominal Surgery (EAS), to highlight key areas of interest and identify those that have most significantly shaped contemporary clinical practice in this newly evolving surgical specialty. This is of increasing relevance as concerns grow regarding the variable and suboptimal outcomes in Emergency General Surgery. The Thomson Reuters Web of Science database was used to search using the terms [Emergency AND Abdom* AND Surg*] to identify all English language, full manuscripts. Results were ranked according to citation number. The top 100 articles were further analysed by subject, author, journal, year of publication, institution, and country of origin. The median (range) citation number of the top 100 out of 7433 eligible papers was 131 (1569-97). The most cited paper (by Goldman et al., Massachusetts General Hospital, New England Journal of Medicine; 1569 citations) focused on cardiac risk stratification in non-cardiac surgery. The Journal of Trauma, Injury, Infection and Critical Care published the most papers and received most citations (n = 19; 2954 citations. The majority of papers were published by centres in the USA (n = 52; 9422 citations), followed by the UK (n = 13; 1816 citations). The most common topics of publication concerned abdominal aneurysm management (n = 26) and emergency gastrointestinal surgery (n = 26). Vascular surgery, risk assessment and gastrointestinal surgery were the areas of focus for 59% of the contemporary most cited emergency abdominal surgery manuscripts. By providing the most influential references this work serves as a guide to what makes a citable emergency surgery paper. Crown Copyright © 2016. Published by Elsevier Ltd. All rights reserved.

Background Electronic health (eHealth) and mobile health (mHealth) approaches to address low physical activity levels, sedentary behavior, and unhealthy diets have received significant research attention. However, attempts to systematically map the entirety of the research field are lacking. This gap can be filled with a bibliometric study, where publication-specific data such as citations, journals, authors, and keywords are used to provide a systematic overview of a specific field. Such analyses will help researchers better position their work. Objective The objective of this review was to use bibliometric data to provide an overview of the eHealth and mHealth research field related to physical activity, sedentary behavior, and diet. Methods The Web of Science (WoS) Core Collection was searched to retrieve all existing and highly cited (as defined by WoS) physical activity, sedentary behavior, and diet related eHealth and mHealth research papers published in English between January 1, 2000 and December 31, 2016. Retrieved titles were screened for eligibility, using the abstract and full-text where needed. We described publication trends over time, which included journals, authors, and countries of eligible papers, as well as their keywords and subject categories. Citations of eligible papers were compared with those expected based on published data. Additionally, we described highly-cited papers of the field (ie, top ranked 1%). Results The search identified 4805 hits, of which 1712 (including 42 highly-cited papers) were included in the analyses. Publication output increased on an average of 26% per year since 2000, with 49.00% (839/1712) of papers being published between 2014 and 2016. Overall and throughout the years, eHealth and mHealth papers related to physical activity, sedentary behavior, and diet received more citations than expected compared with papers in the same WoS subject categories. The Journal of Medical Internet Research published most papers in the field (9.58%, 164/1712). Most papers originated from high-income countries (96.90%, 1659/1717), in particular the United States (48.83%, 836/1712). Most papers were trials and studied physical activity. Beginning in 2013, research on Generation 2 technologies (eg, smartphones, wearables) sharply increased, while research on Generation 1 (eg, text messages) technologies increased at a reduced pace. Reviews accounted for 20 of the 42 highly-cited papers (n=19 systematic reviews). Social media, smartphone apps, and wearable activity trackers used to encourage physical activity, less sedentary behavior, and/or healthy eating were the focus of 14 highly-cited papers. Conclusions This study highlighted the rapid growth of the eHealth and mHealth physical activity, sedentary behavior, and diet research field, emphasized the sizeable contribution of research from high-income countries, and pointed to the increased research interest in Generation 2 technologies. It is expected that the field will grow and diversify further and that reviews and research on most recent technologies will continue to strongly impact the field. PMID:29669703

Background. Bibliometrics are an essential aspect of measuring academic and organizational performance. Aim. This review seeks to describe methods for measuring bibliometrics, identify the strengths and limitations of methodologies, outline strategies for interpretation, summarise evaluation of nursing and midwifery performance, identify implications for metric of evaluation, and specify the implications for nursing and midwifery and implications of social networking for bibliometrics and measures of individual performance. Method. A review of electronic databases CINAHL, Medline, and Scopus was undertaken using search terms such as bibliometrics, nursing, and midwifery. The reference lists of retrieved articles and Internet sources and social media platforms were also examined. Results. A number of well-established, formal ways of assessment have been identified, including h- and c-indices. Changes in publication practices and the use of the Internet have challenged traditional metrics of influence. Moreover, measuring impact beyond citation metrics is an increasing focus, with social media representing newer ways of establishing performance and impact. Conclusions. Even though a number of measures exist, no single bibliometric measure is perfect. Therefore, multiple approaches to evaluation are recommended. However, bibliometric approaches should not be the only measures upon which academic and scholarly performance are evaluated. PMID:24550691

Olfactory ensheathing cell (OEC) transplantation is a promising new approach for the treatment of spinal cord injury (SCI), and an increasing number of scientific publications are devoted to this treatment strategy. This bibliometric analysis was conducted to assess global research trends in OEC transplantation for SCI. All of the data in this study originate from the Web of Science maintained by the Institute for Scientific Information, USA, and includes SCI-EXPANDED, SSCI, A&HCI, CPCI-S, CPCI-SSH, BKCI-S, BKCI-SSH, CCR-EXPANDED and IC. The Institute for Scientific Information's Web of Science was searched using the keywords "olfactory ensheathing cells" or "OECs" or "olfactory ensheathing glia" or "OEG" or "olfactory ensheathing glial cells" or "OEGs" and "spinal cord injury" or "SCI" or "spinal injury" or "spinal transection" for literature published from January 1898 to May 2012. Original articles, reviews, proceedings papers and meeting abstracts, book chapters and editorial materials on OEC transplantation for SCI were included. Simultaneously, unpublished literature and literature for which manual information retrieval was required were excluded. ALL SELECTED LITERATURES ADDRESSING OEC TRANSPLANTATION FOR SCI WERE EVALUATED IN THE FOLLOWING ASPECTS: publication year, document type, language, author, institution, times cited, Web of Science category, core source title, countries/territories and funding agency. In the Web of Science published by the Institute for Scientific Information, the earliest literature record was in April, 1995. Four hundred and fourteen publications addressing OEC transplantation for SCI were added to the data library in the past 18 years, with an annually increasing trend. Of 415 records, 405 publications were in English. Two hundred and fifty-nine articles ranked first in the distribution of document type, followed by 141 reviews. Thirty articles and 20 reviews, cited more than 55 times by the date the publication data were downloaded by us, can be regarded as the most classical references. The journal Experimental Neurology published the most literature (32 records), followed by Glia. The United States had the most literature, followed by China. In addition, Yale University was the most productive institution in the world, while The Second Military Medical University contributed the most in China. The journal Experimental Neurology published the most OEC transplantation literature in the United States, while Neural Regeneration Research published the most in China. This analysis provides insight into the current state and trends in OEC transplantation for SCI research. Furthermore, we anticipate that this analysis will help encourage international cooperation and teamwork on OEC transplantation for SCI to facilitate the development of more effective treatments for SCI.

INTRODUCTION A bibliometric study was carried out to ascertain the volume and impact of scientific literature published on second-generation antipsychotic drugs (SGAs) in Singapore from 1997 to 2011. METHODS A search of the EMBASE and MEDLINE databases was performed to identify articles originating from Singapore that included the descriptors ‘atypic* antipsychotic*’, ‘second-generation antipsychotic*’, ‘clozapine’, ‘risperidone’, ‘olanzapine’, ‘ziprasidone’, ‘quetiapine’, ‘sertindole’, ‘aripiprazole’, ‘paliperidone’, ‘amisulpride’, ‘zotepine’, ‘asenapine’, ‘iloperidone’, ‘lurasidone’, ‘perospirone’ and ‘blonanserin’ in the article titles. Certain bibliometric indicators of production and dispersion (e.g. Price's Law on the increase of scientific literature, and Bradford's Law) were applied, and the participation index of various countries was calculated. The bibliometric data was also correlated with some social and health data from Singapore, such as the total per capita expenditure on health and gross domestic expenditure on research and development. RESULTS From 1997 to 2011, a total of 51 articles on SGAs in Singapore were published. Our results suggested non-fulfilment of Price's Law (r = 0.0648 after exponential adjustment vs. r = 0.2140 after linear adjustment). The most widely studied drugs were clozapine (21 articles), risperidone (16 articles) and olanzapine (8 articles). Division into Bradford zones yielded a nucleus occupied by the Journal of Clinical Psychopharmacology (6 articles) and the Singapore Medical Journal (4 articles). The analysed material was published in a total of 30 journals, with the majority from six journals. Four of these six journals have an impact factor greater than 2. CONCLUSION Publications on SGAs in Singapore are still too few to confirm an exponential growth of scientific literature. PMID:24452974

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

We have explored the collaborative network of the current American Society for Mass Spectrometry (ASMS) membership using bibliometric methods. The analysis shows that 4249 members are connected in a single, large, co-authorship graph, including the majority of the most published authors in the field of mass spectrometry. The map reveals topographical differences between university groups and national laboratories, and that the co-authors with the strongest links have long worked together at the same location. We have collected and summarized information on the geographical distribution of members, showing a high coverage of active researchers in North America and Western Europe. Looking at research fields, we could also identify a number of new or `hot' topics among ASMS members.

2018-01-01

We performed a MeSH term-based bibliometric analysis aiming to assess the publication trends of EAACI journals, namely Allergy, Pediatric Allergy and Immunology (PAI) (from 1990 to 2015) and Clinical and Translational Allergy (CTA) (from its inception in 2011 to 2015). We also aimed to discuss the impact of the creation of CTA in the publication topics of Allergy and PAI. We analysed a total of 1973 articles and 23,660 MeSH terms. Most MeSH terms in the three journals fell in the category of "basic immunology and molecular biology" (BIMB). During the studied period, we observed an increase in the proportion of MeSH terms on BIMB, and a decreasing proportion of terms on allergic rhinitis and aeroallergens. The observed changes in Allergy and PAI publication topics hint at a possible impact from CTA creation.

While research activities on osteoporosis grow constantly, no concise description of the global research architecture exists. Hence, we aim to analyze and depict the world-wide scientific output on osteoporosis combining bibliometric tools, density-equalizing mapping projections and gender analysis. Using the NewQIS platform, we analyzed all osteoporosis-related publications authored from 1900 to 2012 and indexed by the Web of Science. Bibliometric details were analyzed related to quantitative and semi-qualitative aspects. The majority of 57 453 identified publications were original research articles. The USA and Western Europe dominated the field regarding cooperation activity, publication and citation performance. Asia, Africa and South America played a minimal role. Gender analysis revealed a dominance of male scientists in almost all countries except Brazil. Although the scientific performance on osteoporosis is increasing world-wide, a significant disparity in terms of research output was visible between developed and low-income countries. This finding is particularly concerning since epidemiologic evaluations of future osteoporosis prevalences predict enormous challenges for the health-care systems in low-resource countries. Hence, our study underscores the need to address these disparities by fostering future research endeavors in these nations with the aim to successfully prevent a growing global burden related to osteoporosis.

To analyze multi-source data including publications and patents, and try to draw the whole landscape of the research and development community in the field of gene therapy for breast cancer. Publications and patents were collected from the Web of science and databases of the five major patent offices of the world, respectively. Bibliometric methodologies and technology are used to investigate publications/patents, their contents and relationships. A total of 2,043 items published and 947 patents from 1994 to 2013 including "gene therapy for breast cancer" were retrieved. The top five countries in global publication share were USA, China, Germany, Japan and England. On the other hand, USA, Australia, England, South Korea and Japan were the main producers of patents. The universities and enterprises of USA had the highest amount of publication and patents. Adenovirus- and retrovirus-based gene therapies and small interfering RNA (siRNA) interference therapies were the main topics both in publications and patents. The above results show that global research in the field of gene therapy for breast cancer is increasing and the main participants in this field are USA and Canada in North America, China, Japan and South Korea in Asia, and England, Germany, and Italy in Europe. Also, this article demonstrates the usefulness of bibliometrics to address key evaluation questions and define future areas of research.

Protected Designation of Origin (PDO), Protected Geographical Indication (PGI) and Traditional Speciality Guaranteed (TSG): A bibiliometric analysis.

2018-01-01

Despite the importance of the literature on food quality labels in the European Union (PDO, PGI and TSG), our search did not find any review joining the various research topics on this subject. This study aims therefore to consolidate the state of academic research in this field, and so the methodological option was to elaborate a bibliometric analysis resorting to the term co-occurrence technique. Analysis was made of 501 articles on the ISI Web of Science database, covering publications up to 2016. The results of the bibliometric analysis allowed identification of four clusters: "Protected Geographical Indication", "Certification of Olive Oil and Cultivars", "Certification of Cheese and Milk" and "Certification and Chemical Composition". Unlike the other clusters, where the PDO label predominates, the "Protected Geographical Indication" cluster covers the study of PGI products, highlighting analysis of consumer behaviour in relation to this type of product. The focus of studies in the "Certification of Olive Oil and Cultivars" cluster and the "Certification of Cheese and Milk" cluster is the development of authentication methods for certified traditional products. In the "Certification and Chemical Composition" cluster, standing out is analysis of the profiles of fatty acids present in this type of product. Copyright © 2017 Elsevier Ltd. All rights reserved.

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

Cullen, John G

2016-04-01

This article aims to contribute to the growing field of spirituality and nursing management by analysing bibliographic data on peer-reviewed research in the field. Articles on spirituality and nursing management often claim that these fields have grown over the past two decades. This article gathers empirical evidence to test these claims. Bibliometric data on peer-reviewed research articles on nursing, nursing management, spirituality and religion in the Social Sciences Citation Index were analysed to ascertain general trends in publication and citation. The data support claims that research activity and interest in both spirituality and religion in the field of nursing have grown steeply over recent years, and continue to accelerate. The research identified spirituality as a beneficial variable in management, training and/or care scenarios. Critical studies of nursing management spiritual initiatives could add considerably to the growing body of research and theory in this field. It is essential that nurse managers be equipped to foster not only a broader understanding of the variety of faith traditions found in a multi-cultural society, but also to develop an understanding of the ways in which individuals engage in spiritual practice outside traditional religious settings. © 2015 John Wiley & Sons Ltd.

To analyze the 2007 citation count of articles published by the Croatian Medical Journal in 2005-2006 based on data from the Web of Science, Scopus, and Google Scholar. Web of Science and Scopus were searched for the articles published in 2005-2006. As all articles returned by Scopus were included in Web of Science, the latter list was the sample for further analysis. Total citation counts for each article on the list were retrieved from Web of Science, Scopus, and Google Scholar. The overlap and unique citations were compared and analyzed. Proportions were compared using chi(2)-test. Google Scholar returned the greatest proportion of articles with citations (45%), followed by Scopus (42%), and Web of Science (38%). Almost a half (49%) of articles had no citations and 11% had an equal number of identical citations in all 3 databases. The greatest overlap was found between Web of Science and Scopus (54%), followed by Scopus and Google Scholar (51%), and Web of Science and Google Scholar (44%). The greatest number of unique citations was found by Google Scholar (n=86). The majority of these citations (64%) came from journals, followed by books and PhD theses. Approximately 55% of all citing documents were full-text resources in open access. The language of citing documents was mostly English, but as many as 25 citing documents (29%) were in Chinese. Google Scholar shares a total of 42% citations returned by two others, more influential, bibliographic resources. The list of unique citations in Google Scholar is predominantly journal based, but these journals are mainly of local character. Citations received by internationally recognized medical journals are crucial for increasing the visibility of small medical journals but Google Scholar may serve as an alternative bibliometric tool for an orientational citation insight.

2013-01-01

For a number of years ongoing bibliographies of various JPL missions (AIRS, ASTER, Cassini, GRACE, Earth Science, Mars Exploration Rovers (Spirit & Opportunity)) have been compiled by the JPL Library. Mission specific bibliographies are compiled by the Library and sent to mission scientists and managers in the form of regular (usually quarterly) updates. Charts showing publications by years are periodically provided to the ASTER, Cassini, and GRACE missions for supporting Senior Review/ongoing funding requests, and upon other occasions as a measure of the impact of the missions. Basically the Web of Science, Compendex, sometimes Inspec, GeoRef and Aerospace databases are searched for the mission name in the title, abstract, and assigned keywords. All get coded for journal publications that are refereed publications.

Alternatives to the impact factor.

To explore alternative bibliometric markers to the well-established journal impact factor. The bibliometric evolution of a leading ENT journal over a six year period is discussed with critical analysis of a predetermined set of bibliometric alternatives to the journal impact factor. Retrospective review of the bibliometric performance of Clinical Otolaryngology over a six year period. The results of the study reveal that Clinical Otolaryngology has made steady bibliometric progress when the impact factor (IF) is considered with a gradual increase in impact factor from 1.098 in 2006 to a peak of 2.393 in 2011. Self-citation rates reported by the Journal Citation Report (JCR) demonstrated a significant decline during 2007 with a reported self-citation rate of 0%. The SCImago Journal Rank (SJR) database however recorded a self-citation rate of 67. Independent evaluation demonstrated a 56 self-citations during this period. The percentage of review articles published remained stable during the period in question. A lagged association between the number of review manuscripts and the IF failed to demonstrate any significant correlation (r = -0.19). Comparison between the IF and the Eigen factor (EF) as well as the SJR yielded negative correlation (r = -0.46) and (r = -0.35) respectively. The Article Influence score (AIS) and Source Normalised Impact per Paper (SNIP) were the only bibliometric alternatives to demonstrate a positive correlation when compared to the IF (r = 0.94) and (r = 0.66) respectively. The necessity of bibliometric markers cannot be called into question however the most widely employed of these, the journal impact factor has come under increased scrutiny of late. Despite some of the advantages offered by novel bibliometric markers, these do not necessarily compare favourably to the IF with regards to bibliometric performance. The only two markers to demonstrate a positive correlation when compared to the IF were the AI score and SNIP which would suggest that these are potential alternatives to the IF and have the added advantage that they are open access.

Substance use disorders in Arab countries: research activity and bibliometric analysis

PubMed Central

2014-01-01

Background Substance use disorders, which include substance abuse and substance dependence, are present in all regions of the world including Middle Eastern Arab countries. Bibliometric analysis is an increasingly used tool for research assessment. The main objective of this study was to assess research productivity in the field of substance use disorders in Arab countries using bibliometric indicators. Methodology Original or review research articles authored or co-authored by investigators from Arab countries about substance use disorders during the period 1900 – 2013 were retrieved using the ISI Web of Science database. Research activity was assessed by analyzing the annual research productivity, contribution of each Arab country, names of journals, citations, and types of abused substances. Results Four hundred and thirteen documents in substance use disorders were retrieved. Annual research productivity was low but showed a significant increase in the last few years. In terms of quantity, Kingdom of Saudi Arabia (83 documents) ranked first in research about substance use disorders while Lebanon (17.4 documents per million) ranked first in terms of number of documents published per million inhabitants. Retrieved documents were found in different journal titles and categories, mostly in Drug and Alcohol Dependence Journal. Authors from USA appeared in 117 documents published by investigators from Arab countries. Citation analysis of retrieved documents showed that the average citation per document was 10.76 and the h - index was 35. The majority of retrieved documents were about tobacco and smoking (175 documents) field while alcohol consumption and abuse research was the least with 69 documents. Conclusion The results obtained suggest that research in this field was largely neglected in the past. However, recent research interest was observed. Research output on tobacco and smoking was relatively high compared to other substances of abuse like illicit drugs and medicinal agents. Governmental funding for academics and mental health graduate programs to do research in the field of substance use disorders is highly recommended. PMID:25148888

Bibliometrics is a set of methods used to study or measure texts and information. While bibliometric methods are most often used in the field of library and information science, bibliometrics variables have wide applications in other areas. One popular bibliometric variable is Garfield's Impact Factor (IF). IF is used to explore the impact of a given field, the impact of a set of researchers, or the impact of a particular paper. This variable is used to assess academic output and it is believed to affect adversely the traditional approach and assessment of scientific research. In our country, the members of the evaluation committees of intensive research institutions, e.g. the National Scientific and Technical Research Council (CONICET) use IF to assess the quality of research. This article revises the exponential growth of bibliometrics and attempts to expose the overall dissatisfaction with the analytical quality of IF. Such dissatisfaction is expressed in the number of investigations attempting to obtain a better variable of improved analytical quality.

Visibility of medical informatics regarding bibliometric indices and databases

PubMed Central

2011-01-01

Background The quantitative study of the publication output (bibliometrics) deeply influences how scientific work is perceived (bibliometric visibility). Recently, new bibliometric indices and databases have been established, which may change the visibility of disciplines, institutions and individuals. This study examines the effects of the new indices on the visibility of Medical Informatics. Methods By objective criteria, three sets of journals are chosen, two representing Medical Informatics and a third addressing Internal Medicine as a benchmark. The availability of index data (index coverage) and the aggregate scores of these corpora are compared for journal-related (Journal impact factor, Eigenfactor metrics, SCImago journal rank) and author-related indices (Hirsch-index, Egghes G-index). Correlation analysis compares the dependence of author-related indices. Results The bibliometric visibility depended on the research focus and the citation database: Scopus covers more journals relevant for Medical Informatics than ISI/Thomson Reuters. Journals focused on Medical Informatics' methodology were negatively affected by the Eigenfactor metrics, while the visibility profited from an interdisciplinary research focus. The correlation between Hirsch-indices computed on citation databases and the Internet was strong. Conclusions The visibility of smaller technology-oriented disciplines like Medical Informatics is changed by the new bibliometric indices and databases possibly leading to suitably changed publication strategies. Freely accessible author-related indices enable an easy and adequate individual assessment. PMID:21496230

Scientific publication in academic literature is a key venue in which the U.S. Department of Defense's Global Emerging Infections Surveillance and Response System (GEIS) program disseminates infectious disease surveillance data. Bibliometric analyses are tools to evaluate scientific productivity and impact of published research, yet are not routinely used for disease surveillance. Our objective was to incorporate bibliometric indicators to measure scientific productivity and impact of GEIS-funded infectious disease surveillance, and assess their utility in the management of the GEIS surveillance program. Metrics on GEIS program scientific publications, project funding, and countries of collaborating institutions from project years 2006 to 2012 were abstracted from annual reports and program databases and organized by the six surveillance priority focus areas: respiratory infections, gastrointestinal infections, febrile and vector-borne infections, antimicrobial resistance, sexually transmitted infections, and capacity building and outbreak response. Scientific productivity was defined as the number of scientific publications in peer-reviewed literature derived from GEIS-funded projects. Impact was defined as the number of citations of a GEIS-funded publication by other peer-reviewed publications, and the Thomson Reuters 2-year journal impact factor. Indicators were retrieved from the Web of Science and Journal Citation Report. To determine the global network of international collaborations between GEIS partners, countries were organized by the locations of collaborating institutions. Between 2006 and 2012, GEIS distributed approximately US $330 million to support 921 total projects. On average, GEIS funded 132 projects (range 96-160) with $47 million (range $43 million-$53 million), annually. The predominant surveillance focus areas were respiratory infections with 317 (34.4%) projects and $225 million, and febrile and vector-borne infections with 274 (29.8%) projects and $45 million. The number of annual respiratory infections-related projects peaked in 2006 and 2009. The number of febrile and vector-borne infections projects increased from 29 projects in 2006 to 58 in 2012. There were 651 articles published in 147 different peer-reviewed journals, with an average Thomson Reuters 2-year journal impact factor of 4.2 (range 0.3-53.5). On average, 93 articles were published per year (range 67-117) with $510,000 per publication. Febrile and vector-borne, respiratory, and gastrointestinal infections had 287, 167, and 73 articles published, respectively. Of the 651 articles published, 585 (89.9%) articles were cited at least once (range 1-1,045). Institutions from 90 countries located in all six World Health Organization regions collaborated with surveillance projects. These findings summarize the GEIS-funded surveillance portfolio between 2006 and 2012, and demonstrate the scientific productivity and impact of the program in each of the six disease surveillance priority focus areas. GEIS might benefit from further financial investment in both the febrile and vector-borne and sexually transmitted infections surveillance priority focus areas and increasing peer-reviewed publications of surveillance data derived from respiratory infections projects. Bibliometric indicators are useful to measure scientific productivity and impact in surveillance systems; and this methodology can be utilized as a management tool to assess future changes to GEIS surveillance priorities. Additional metrics should be developed when peer-reviewed literature is not used to disseminate noteworthy accomplishments. Reprint & Copyright © 2017 Association of Military Surgeons of the U.S.

2014-01-01

Background: Article characteristics and trends have been elucidated for other physical therapy-focused journals using content and bibliometric analysis. These findings are important for assessing the current state of a journal and for guiding future publication of research. To date, these analyses have not been performed for the Journal of Manual & Manipulative Therapy (JMMT). Objective: To describe content and trends for articles published in JMMT over a 20-year period (1993–2012). Methods: Journal articles were coded using previously-established domains (article type, participant type, research design, study purpose, and clinical condition). Total publications and proportion of publications based on domain were described. Articles specific to manual therapy intervention were examined and compared to data from other physical therapy-focused journals. Impact by citation and author was examined using bibliometric software. Results: Journal of Manual & Manipulative Therapy was found to have a recent acceleration in the number of articles published annually. Over time, topical reviews have decreased in favor of research reports. However, rigorous study designs have represented only a small portion of total journal content, and case reports have maintained a consistent publication presence. Manual therapy intervention articles in JMMT are predominantly case designs, however are similar in characteristics to manual therapy intervention articles published in other physical therapy-focused journals. For JMMT articles overall and manual therapy intervention articles across journals, young to middle-aged symptomatic adults with low back and/or neck pain were the most common study participants. Discussion: Increases in the number of papers and a move toward research reports were observed in JMMT over the 20-year period. Considerations for the future were outlined, including the publication of articles with more rigorous research designs. Manual therapy research for adolescents and older adults and for upper and lower extremity conditions should also be considered as priorities for the future. PMID:25395826

The aim of this study is to compare the quantity and quality of scientific publications in transplantation fields that were written by researchers from Mainland China, Japan, South Korea and Taiwan in the East Asia region. East Asia. Articles except editorials, conference abstracts, letters, news and corrections published in 25 transplantation journals from 2006 to 2015 were screened with the Web of Science database. The number of total and annual articles, article types (study design and transplantation site), impact factor, citations and articles in the high-impact journals was determined to assess the quantity and quality of transplantation research from East Asia. The correlation of socioeconomic factors and annual publications was also analysed. From 2006 to 2015, there were 47 141 articles published in transplantation journals, of which researchers from Japan published 3694 articles, followed by Mainland China, South Korea and Taiwan with 2778, 1643 and 951 articles, respectively. Similar trends were observed in accumulated impact factor, accumulated citations, articles in the high-impact journals and articles on transplantation site. Publications from Japan had the highest average impact factor and citation, while those from Mainland China had the lowest. Additionally, in terms of study design, authors from Mainland China contributed to most clinical trials and randomised controlled trials, but authors from Japan contributed to most case reports. The annual numbers of articles from Mainland China and South Korea increased linearly (p<0.05), but those from Japan and Taiwan remained stable for the period studied. The annual numbers of articles from Mainland China and South Korea were positively correlated with gross domestic product (p<0.05). Transplantation research productivity in East Asia is highly skewed, with gross domestic product having a significant positive correlation. Mainland China still lags far behind Japan in most bibliometric indicators; thus, there is vast room for improvement. Published by the BMJ Publishing Group Limited.

2015-01-01

Background The European & Developing Countries Clinical Trials Partnership (EDCTP) is a partnership of European and sub-Saharan African countries that aims to accelerate the development of medical interventions against poverty-related diseases (PRDs). A bibliometric analysis was conducted to 1) measure research output from European and African researchers on PRDs, 2) describe collaboration patterns, and 3) assess the citation impact of clinical research funded by EDCTP. Methodology/Principal Findings Disease-specific research publications were identified in Thomson Reuters Web of Science using search terms in titles, abstracts and keywords. Publication data, including citation counts, were extracted for 2003–2011. Analyses including output, share of global papers, normalised citation impact (NCI), and geographical distribution are presented. Data are presented as five-year moving averages. European EDCTP member countries accounted for ~33% of global research output in PRDs and sub-Saharan African countries for ~10% (2007–2011). Both regions contributed more to the global research output in malaria (43.4% and 22.2%, respectively). The overall number of PRD papers from sub-Saharan Africa increased markedly (>47%) since 2003, particularly for HIV/AIDS (102%) and tuberculosis (TB) (81%), and principally involving Southern and East Africa. For 2007–2011, European and sub-Saharan African research collaboration on PRDs was highly cited compared with the world average (NCI in brackets): HIV/AIDS 1.62 (NCI: 1.16), TB 2.11 (NCI: 1.06), malaria 1.81 (NCI: 1.22), and neglected infectious diseases 1.34 (NCI: 0.97). The NCI of EDCTP-funded papers for 2003–2011 was exceptionally high for HIV/AIDS (3.24), TB (4.08) and HIV/TB co-infection (5.10) compared with global research benchmarks (1.14, 1.05 and 1.35, respectively). Conclusions The volume and citation impact of papers from sub-Saharan Africa has increased since 2003, as has collaborative research between Europe and sub-Saharan Africa. >90% of publications from EDCTP-funded research were published in high-impact journals and are highly cited. These findings corroborate the benefit of collaborative research on PRDs. PMID:26262756

To investigate the distribution and hot spots of literatures on headache by bibliometric analysis in order to provide reference for further study. Literatures that contained headache or migraine in text words published in 2011 in PubMed databases (www.ncbi.nlm.nih.gov/Pubmed) were searched. Journals, countries and subjects were bibliometrically analysed. There were 3683 papers involved to headache published in PubMed in 2011, of which 1527 papers were on headache research. The number of papers on headache research published by USA was the most followed by Italy and Germany (USA 23.25%, Italy 10.74%, Germany 5.83%). The mainly studied subjects were therapy (29.60%), pathophysiology (18.66%) and etiology (16.31%). 14.86% papers published in Cephalalgia, which is one of the most important journals, reported negative results. The emphasis of headache research was on migraine. Therapy, pathophysiology and etiology were the hot spot. Literatures with negative result attracted authors to give the more attention.

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

A bibliometric analysis based on the Science Citation Index Expanded from Web of Science was carried out to provide insights into research activities and trends of the environmental monitoring from 1993 to 2012. Study emphases covered publication outputs, language, categories, journals, countries/territories, institutions, words, and hot issues. The results indicated that the annual output of environmental monitoring publications increased steadily. The environmental sciences and analytical chemistry were the two most common categories. Environmental Monitoring and Assessment published the most articles. The USA and the UK ranked in the top two in terms of all five indicators. The U.S. Environmental Protection Agency took the leading position of the institutions in terms of publication output. The synthesized analysis by words in title, author keywords, and KeyWords Plus provided important clues for hot issues. Researchers paid more attention on water environment monitoring than other environmental factors. The contaminants including organic contaminants, heavy metal, and radiation were most common research focuses, and the organic contaminants and heavy metal of the degree of concern were gradually rising. Sensor and biosensor played an important role in the field of environmental monitoring devices. In addition to conventional device detection method, the remote sensing, GIS, and wireless sensor networks were the mainstream environmental monitoring methods. The international organization, social awareness, and the countries' positive and effective political and policies promoted the published articles.

2017-02-01

A bibliometric analysis was conducted to examine the progress and future research trends of non-point source (NPS) pollution during the years 1991-2015 based on the Science Citation Index Expanded (SCI-Expanded) of Web of Science (WoS). The publications referencing NPS pollution were analyzed including the following aspects: document type, publication language, publication output and characteristics, subject category, source journal, distribution of country and institution, author keywords, etc. The results indicate that the study of NPS pollution demonstrated a sharply increasing trend since 1991. Article and English were the most commonly used document type and language. Environmental sciences and ecology, water resources, and engineering were the top three subject categories. Water science and technology ranked first in distribution of journal, followed by Science of the total environment and Environmental Monitoring and Assessment. The USA took a leading position in both quantity and quality, playing an important role in the research field of NPS pollution, followed by the UK and China. The most productive institution was the Chinese Academy of Sciences (Chinese Acad Sci), followed by Beijing Normal University and US Department of Agriculture's Agricultural Research Service (USDA ARS). The analysis of author keywords indicates that the major hotspots of NPS pollution from 1991 to 2015 contained "water," "model," "agriculture," "nitrogen," "phosphorus," etc. The results provide a comprehensive understanding of NPS pollution research and help readers to establish the future research directions.

The Accreditation Council for Graduate Medical Education (ACGME) Common Program Requirements state that faculty must establish and maintain an environment of inquiry and scholarship. Bibliometrics, the statistical analysis of written publications, assesses scientific productivity and impact. The goal of this study was to understand the state of scholarship at Pediatric Surgery training programs. Following IRB approval, Scopus was used to generate bibliometric profiles for US Pediatric Surgery training programs and faculty. Statistical analyses were performed. Information was obtained for 430 surgeons (105 female) from 48 US training programs. The mean lifetime h-index/surgeon for programs was 14.4 +/- 4.7 (6 programs above 1 SD, 9 programs below 1 SD). The mean 5-yearh-index/surgeon for programs was 3.92 +/- 1.5 (7 programs above 1 SD, 8 programs below 1 SD). Programs accredited after 2000 had a lower lifetime h-index than those accredited before 2000 (p=0.0378). Female surgeons had a lower lifetime h-index (p<0.0001), 5-yearh-index (p=0.0049), and m-quotient (p<0.0001) compared to males. Mean lifetime h-index increased with academic rank (p<0.0001), with no gender differences beyond the assistant professor rank (p=NS). Variability was identified based on institution, gender, and rank. This information can be used for benchmarking the academic productivity of faculty and programs and as an adjunct in promotion/tenure decisions. Original Research. n/a. Copyright © 2018 Elsevier Inc.

Motivation Measures in Sport: A Critical Review and Bibliometric Analysis.

PubMed

Clancy, Rachel B; Herring, Matthew P; Campbell, Mark J

2017-01-01

Motivation is widely-researched, in both sport psychology and other fields. As rigorous measurement is essential to understanding this latent construct, a critical appraisal of measurement instruments is needed. Thus, the purpose of this review was to evaluate the six most highly cited motivation measures in sport. Peer-reviewed articles published prior to August 2016 were searched to identify the six most highly cited motivation questionnaires in sport: Sport Motivation Scale (SMS), Intrinsic Motivation Inventory (IMI), Situational Motivational Scale (SIMS), Perceptions of Success Questionnaire (POSQ), Behavioural Regulation in Sport Questionnaire (BRSQ), and Task and Ego Orientation in Sport Questionnaire (TEOSQ). The questionnaires were then evaluated and discussed in four sections: Development, Reliability, Correlates, and Summary. Bibliometric data were also calculated (average weighted impact factor) and assessed (e.g., citations per year) to evaluate the impact of the use of each questionnaire. Despite some variance in their psychometric properties, conceptualization, structure, and utility, the six questionnaires are psychometrically strong instruments for quantifying motivation that are widely supported in the literature. Bibliometric analyses suggested that the IMI ranks first and the SMS ranks sixth according to the average weighted impact factors of their original publications. Consideration of each questionnaire's psychometric strengths/limitations, and conceptualization of motivation in the context of specific research questions should guide researchers in selecting the most appropriate instrument to measure motivation in sport. The average weighted impact factor of each questionnaire is a useful value to consider as well. With these points in mind, recommendations are provided.

Measuring Individual Performance with Comprehensive Bibliometric Reports as an Alternative to h-Index Values

PubMed Central

2018-01-01

The h-index is frequently used to measure the performance of single scientists in Korea (and beyond). No single indicator alone, however, is able to provide a stable and complete assessment of performance. The Stata command bibrep.ado is introduced which automatically produces bibliometric reports for single researchers (senior researchers working in the natural or life sciences). The user of the command receives a comprehensive bibliometric report which can be used in research evaluation instead of the h-index. PMID:29713257

Electronic health (eHealth) and mobile health (mHealth) approaches to address low physical activity levels, sedentary behavior, and unhealthy diets have received significant research attention. However, attempts to systematically map the entirety of the research field are lacking. This gap can be filled with a bibliometric study, where publication-specific data such as citations, journals, authors, and keywords are used to provide a systematic overview of a specific field. Such analyses will help researchers better position their work. The objective of this review was to use bibliometric data to provide an overview of the eHealth and mHealth research field related to physical activity, sedentary behavior, and diet. The Web of Science (WoS) Core Collection was searched to retrieve all existing and highly cited (as defined by WoS) physical activity, sedentary behavior, and diet related eHealth and mHealth research papers published in English between January 1, 2000 and December 31, 2016. Retrieved titles were screened for eligibility, using the abstract and full-text where needed. We described publication trends over time, which included journals, authors, and countries of eligible papers, as well as their keywords and subject categories. Citations of eligible papers were compared with those expected based on published data. Additionally, we described highly-cited papers of the field (ie, top ranked 1%). The search identified 4805 hits, of which 1712 (including 42 highly-cited papers) were included in the analyses. Publication output increased on an average of 26% per year since 2000, with 49.00% (839/1712) of papers being published between 2014 and 2016. Overall and throughout the years, eHealth and mHealth papers related to physical activity, sedentary behavior, and diet received more citations than expected compared with papers in the same WoS subject categories. The Journal of Medical Internet Research published most papers in the field (9.58%, 164/1712). Most papers originated from high-income countries (96.90%, 1659/1717), in particular the United States (48.83%, 836/1712). Most papers were trials and studied physical activity. Beginning in 2013, research on Generation 2 technologies (eg, smartphones, wearables) sharply increased, while research on Generation 1 (eg, text messages) technologies increased at a reduced pace. Reviews accounted for 20 of the 42 highly-cited papers (n=19 systematic reviews). Social media, smartphone apps, and wearable activity trackers used to encourage physical activity, less sedentary behavior, and/or healthy eating were the focus of 14 highly-cited papers. This study highlighted the rapid growth of the eHealth and mHealth physical activity, sedentary behavior, and diet research field, emphasized the sizeable contribution of research from high-income countries, and pointed to the increased research interest in Generation 2 technologies. It is expected that the field will grow and diversify further and that reviews and research on most recent technologies will continue to strongly impact the field. ©Andre Matthias Müller, Carol A Maher, Corneel Vandelanotte, Melanie Hingle, Anouk Middelweerd, Michael L Lopez, Ann DeSmet, Camille E Short, Nicole Nathan, Melinda J Hutchesson, Louise Poppe, Catherine B Woods, Susan L Williams, Petra A Wark.

Aim To analyze the 2007 citation count of articles published by the Croatian Medical Journal in 2005-2006 based on data from the Web of Science, Scopus, and Google Scholar. Methods Web of Science and Scopus were searched for the articles published in 2005-2006. As all articles returned by Scopus were included in Web of Science, the latter list was the sample for further analysis. Total citation counts for each article on the list were retrieved from Web of Science, Scopus, and Google Scholar. The overlap and unique citations were compared and analyzed. Proportions were compared using χ2-test. Results Google Scholar returned the greatest proportion of articles with citations (45%), followed by Scopus (42%), and Web of Science (38%). Almost a half (49%) of articles had no citations and 11% had an equal number of identical citations in all 3 databases. The greatest overlap was found between Web of Science and Scopus (54%), followed by Scopus and Google Scholar (51%), and Web of Science and Google Scholar (44%). The greatest number of unique citations was found by Google Scholar (n = 86). The majority of these citations (64%) came from journals, followed by books and PhD theses. Approximately 55% of all citing documents were full-text resources in open access. The language of citing documents was mostly English, but as many as 25 citing documents (29%) were in Chinese. Conclusion Google Scholar shares a total of 42% citations returned by two others, more influential, bibliographic resources. The list of unique citations in Google Scholar is predominantly journal based, but these journals are mainly of local character. Citations received by internationally recognized medical journals are crucial for increasing the visibility of small medical journals but Google Scholar may serve as an alternative bibliometric tool for an orientational citation insight.

Modern bibliographic databases provide the basis for scientific research and its evaluation. While their content and structure differ substantially, there exist only informal notions on their reliability. Here we compare the topological consistency of citation networks extracted from six popular bibliographic databases including Web of Science, CiteSeer and arXiv.org. The networks are assessed through a rich set of local and global graph statistics. We first reveal statistically significant inconsistencies between some of the databases with respect to individual statistics. For example, the introduced field bow-tie decomposition of DBLP Computer Science Bibliography substantially differs from the rest due to the coverage of the database, while the citation information within arXiv.org is the most exhaustive. Finally, we compare the databases over multiple graph statistics using the critical difference diagram. The citation topology of DBLP Computer Science Bibliography is the least consistent with the rest, while, not surprisingly, Web of Science is significantly more reliable from the perspective of consistency. This work can serve either as a reference for scholars in bibliometrics and scientometrics or a scientific evaluation guideline for governments and research agencies. PMID:25263231

Many articles have been published on pituitary adenomas. Bibliometric analyses are helpful for determining the most impactful studies within a field. To identify the top 100 most-cited articles on pituitary adenomas using the bibliometric analysis method. We searched the Thomson Reuters Web of Science on March 31, 2018. Articles were listed in descending order by the total citation (TC) number, and the most-cited articles on pituitary adenomas were identified and analyzed. The most-cited articles were published between 1970 and 2014, with 1999 as the most prolific year. Growth hormone-secreting pituitary adenoma was the most commonly studied tumor subtype (43%), and in clinical studies, treatment options and follow-up were the most important research focuses (62%). The average number of TCs was 326, and the average number of annual citations (ACs) was 17. More review articles were published in the last decade, and the average number of ACs was higher for this decade than for previous decades. Twenty-one articles were recognized as "Citation Classics" with a TC number>400. Twenty-five journals published the top 100 works; the Journal of Clinical Endocrinology and Metabolism published the most articles (25%). The most articles (43%) were published in the United States. S. Melmed authored the greatest number of publications (14%). Departments of Medicine (32%) and Endocrinology (32%) contributed to the largest number of articles. This study identified the research focuses and trends regarding pituitary adenoma and provides key references for investigators in guiding future pituitary adenoma research.

To identify global research trends of muscle-derived stem cells (MDSCs) using a bibliometric analysis of the Web of Science, Research Portfolio Online Reporting Tools of the National Institutes of Health (NIH), and the Clinical Trials registry database (ClinicalTrials.gov). We performed a bibliometric analysis of data retrievals for MDSCs from 2002 to 2011 using the Web of Science, NIH, and ClinicalTrials.gov. (1) Web of Science: (a) peer-reviewed articles on MDSCs that were published and indexed in the Web of Science. (b) Type of articles: original research articles, reviews, meeting abstracts, proceedings papers, book chapters, editorial material and news items. (c) Year of publication: 2002-2011. (d) Citation databases: Science Citation Index-Expanded (SCI-E), 1899-present; Conference Proceedings Citation Index-Science (CPCI-S), 1991-present; Book Citation Index-Science (BKCI-S), 2005-present. (2) NIH: (a) Projects on MDSCs supported by the NIH. (b) Fiscal year: 1988-present. (3) ClinicalTrials.gov: All clinical trials relating to MDSCs were searched in this database. (1) Web of Science: (a) Articles that required manual searching or telephone access. (b) We excluded documents that were not published in the public domain. (c) We excluded a number of corrected papers from the total number of articles. (d) We excluded articles from the following databases: Social Sciences Citation Index (SSCI), 1898-present; Arts & Humanities Citation Index (A&HCI), 1975-present; Conference Proceedings Citation Index - Social Science & Humanities (CPCI-SSH), 1991-present; Book Citation Index - Social Sciences & Humanities (BKCI-SSH), 2005-present; Current Chemical Reactions (CCR-EXPANDED), 1985-present; Index Chemicus (IC), 1993-present. (2) NIH: (a) We excluded publications related to MDSCs that were supported by the NIH. (b) We limited the keyword search to studies that included MDSCs within the title or abstract. (3) ClinicalTrials.gov: (a) We excluded clinical trials that were not in the ClinicalTrials.gov database. (b) We excluded clinical trials that dealt with stem cells other than MDSCs in the ClinicalTrials.gov database. (1) Type of literature; (2) annual publication output; (3) distribution according to journals; (4) distribution according to country; (5) distribution according to institution; (6) top cited authors over the last 10 years; (7) projects financially supported by the NIH; and (8) clinical trials registered. (1) In all, 802 studies on MDSCs appeared in the Web of Science from 2002 to 2011, almost half of which derived from American authors and institutes. The number of studies on MDSCs has gradually increased over the past 10 years. Most papers on MDSCs appeared in journals with a particular focus on cell biology research, such as Experimental Cell Research, Journal of Cell Science, and PLoS One. (2) Eight MDSC research projects have received over US$6 billion in funding from the NIH. The current project led by Dr. Johnny Huard of the University of Pittsburgh-"Muscle-Based Tissue Engineering to Improve Bone Healing"-is supported by the NIH. Dr. Huard has been the most productive and top-cited author in the field of gene therapy and adult stem cell research in the Web of Science over last 10 years. (3) On ClinicalTrials.gov, "Muscle Derived Cell Therapy for Bladder Exstrophy Epispadias Induced Incontinence" Phase 1 is registered and sponsored by Johns Hopkins University and has been led by Dr. John P. Gearhart since November 2009. From our analysis of the literature and research trends, we found that MDSCs may offer further benefits in regenerative medicine.

To assess Australian health and medical research (HMR) investment returns by measuring the trends in HMR expenditure and PubMed publications by Australian authors. Bibliometric analysis collating Australian HMR expenditure reported by the Australian Institute of Health and Welfare and Australian HMR publications indexed in PubMed. Similar methods were applied to data from the United Kingdom and New Zealand. From financial year 2000/01 through 2011/12, HMR investment increased by 232% from $1.49 to $4.94 billion (current prices adjusted for inflation), while PubMed publications increased by 123% from 10,696 to 23,818. The average HMR investment required for a single PubMed publication rose by 49% from $139,304 in 2000/01 to $207,364 in 2011/12. Quality analyses showed an increase in systematic reviews, cohort studies and clinical trials, and a decrease in publications in PubMed's core clinical journal collection. Comparisons with New Zealand and the United Kingdom showed that Australia has had the greatest overall percentage increase in gross publication numbers and publications per capita. Our analyses confirm that increased HMR expenditure is associated with an increase in HMR publications in PubMed. Tracking HMR investment outcomes using this method could be useful for future policy and funding decisions at a federal and specific institution level. © 2015 Public Health Association of Australia.

Although cited reference studies are common in the library and information science literature, they are rarely performed in non-academic institutions or in the atmospheric and oceanic sciences. In this paper, we analyze over 400,000 cited references made by authors affiliated with the National Oceanic and Atmospheric Administration between 2009 and 2013. Our results suggest that these methods can be applied to research libraries in a variety of institutions, that the results of analyses performed at one institution may not be applicable to other institutions, and that cited reference analyses should be periodically updated to reflect changes in authors’ referencing behavior.

Bibliometric studies are increasingly being used for research assessments. Bibliometric indicators involve the application of statistical methods to scientific publications to obtain the bibliographics for each journal. The main objective of this study was to conduct a bibliometric evaluation of Human & Experimental Toxicology retrieved from the Scopus database. This study obtained data from Scopus published from 1 January 2003 till 31 December 2012. The keywords entered in Scopus to accomplish the objective of this study were 'Human', 'Experimental' and 'Toxicology' as 'Source Title'. Research productivity was evaluated based on a methodology developed and used in other bibliometric studies by analysing (a) total and trends in Human & Experimental Toxicology contributions in research between 2003 and 2012; (b) Human & Experimental Toxicology authorship patterns and productivity; (c) collaboration patterns; and (d) the citations received by the publications. There were 1229 research articles published in Human & Experimental Toxicology. Of the articles included, 947 (77.1%) were original articles and 104 (8.5%) were review articles. The Hirsch-index of the retrieved documents was 35. The largest number of publications in Human & Experimental Toxicology was from the United States (19.6%), followed by India (12.8%) and Turkey (10.9%). The total number of citations was 9119, with a median (interquartile range) of 3 (1-9) in 6797 documents. The highest median (interquartile range) number of citations was 8 (2.7-12.7) for France, followed by 7.5 (2-22.5) for Iran and 6 (3-13.5) for the United Kingdom. The country most often citing articles that were published in Human & Experimental Toxicology was the United States, which made citations in 1508 documents, followed by India with citations in 792 documents. The documents in Human & Experimental Toxicology focus principally on original data, with very few review articles. Review articles tend to have higher citation rates than original articles, and hence, the editors and authors of Human & Experimental Toxicology might usefully promote the submission of reviews in the future to improve the impact of the journal.

There is a paucity of information about the oral pathology related articles published in a pathology journal. This study aimed to audit the oral pathology related articles published in Iranian Journal of Pathology (Iran J Pathol) from 2006 to 2015. Bibliometric analysis of issues of Iran J Pathol from 2006 to 2015 was performed using web-based search. The articles published were analyzed for type of article and individual topic of oral pathology. The articles published were also checked for authorship trends. Out of the total 49 published articles related to oral pathology, case reports (21) and original articles (18) contributed the major share. The highest number of oral pathology related articles was published in 2011, 2014 and 2015 with 8 articles each and the least published year was 2012 with 1 article. Among the oral pathology related articles published, spindle cell neoplasms (7) followed by salivary gland tumors (5), jaw tumors (4), oral granulomatous conditions (4), lymphomas (4), oral cancer (3) and odontogenic cysts (3) form the major attraction of the contributors. The largest numbers of published articles related to oral pathology were received from Tehran University of Medical Sciences; Tehran (7) followed by Mashhad University of Medical Sciences, Mashhad (6) and Shahid Beheshti University of Medical Sciences, Tehran (5). This paper may be considered as a baseline study for the bibliometric information regarding oral pathology related articles published in a pathology journal.

Research on dissociative seizures: A bibliometric analysis and visualization of the scientific landscape.

2018-06-01

Dissociative seizures are a common and often elusive differential diagnosis in epilepsy centers. Considering their high prevalence, long diagnostic delays, and disappointing rates of treatment response, scientific research dedicated to dissociative seizures is surprisingly scarce. In order to chart the scientific landscape of dissociative seizures and to visualize thematic clusters and trends in research, a comprehensive bibliometric analysis was performed. The Web of Science database was examined to identify relevant English language documents from the last half-century. A total of 1751 documents with titles referring to dissociative seizures were identified. Automated textual analysis of all titles and abstracts revealed that research clusters around three major topics: differential diagnosis in epilepsy centers, management and treatment, and psychopathology. Time analysis of term networks revealed that the focus of clinical research has moved from diagnostic procedures to treatment approaches. Furthermore, interest within etiological research is shifting from an emphasis on early life trauma and personality traits to the role of anxiety and emotion regulation. With respect to individual contributing authors, a relatively small network of prolific scientists with a remarkable degree of collaboration emerges. By mapping relevant publications, it becomes evident that dissociative seizures still represent a subject mostly within the realm of neurology and epileptology, with a tendency to settle in the latter domain. This analysis sheds light on an important niche subject and highlights trends in research focus and output. Copyright © 2018 Elsevier Inc. All rights reserved.

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.

Background: There is a paucity of information about the oral pathology related articles published in a pathology journal. This study aimed to audit the oral pathology related articles published in Iranian Journal of Pathology (Iran J Pathol) from 2006 to 2015. Methods: Bibliometric analysis of issues of Iran J Pathol from 2006 to 2015 was performed using web-based search. The articles published were analyzed for type of article and individual topic of oral pathology. The articles published were also checked for authorship trends. Results: Out of the total 49 published articles related to oral pathology, case reports (21) and original articles (18) contributed the major share. The highest number of oral pathology related articles was published in 2011, 2014 and 2015 with 8 articles each and the least published year was 2012 with 1 article. Among the oral pathology related articles published, spindle cell neoplasms (7) followed by salivary gland tumors (5), jaw tumors (4), oral granulomatous conditions (4), lymphomas (4), oral cancer (3) and odontogenic cysts (3) form the major attraction of the contributors. The largest numbers of published articles related to oral pathology were received from Tehran University of Medical Sciences; Tehran (7) followed by Mashhad University of Medical Sciences, Mashhad (6) and Shahid Beheshti University of Medical Sciences, Tehran (5). Conclusion: This paper may be considered as a baseline study for the bibliometric information regarding oral pathology related articles published in a pathology journal. PMID:27799973

[Psychotherapy research in the German-speaking community--a bibliometric analysis of three journals].

Psychotherapy research has often been considered a neglected topic in clinical psychology, psychosomatic medicine, and psychiatry because of its massive organizational and financial demands. However, it is unclear whether this assumption actually reflects the research activities in the field. We conducted a bibliometric analysis of the annual volumes for 2008 and 2009 of three clinical journals published in German. All publications referring to facets of psychotherapy research were analysed. About 30% of the publications dealt with issues of psychotherapy research. Outcome and process studies were about equally distributed. Process research frequently focused on patient variables as outcome predictors. Outcome studies most often presented effectiveness studies with rather small sample sizes. Psychotherapy research is a well-represented and multifaceted field in the German speaking research community. However, the traditional distinction between efficacy and process research among the various schools of psychotherapy research may be hampering further developments in this branch. The government-funded research networks may turn out to be promising approaches to overcoming some of the obstacles of classic psychotherapy research.

Infectious diseases research in a low-income country like Afghanistan is important. In this study an internet-based database Pubmed was used for bibliometric analysis of infectious diseases research activity. Research publications entries in PubMed were analysed according to number of publications, topic, publication type, and country of investigators. Between 2002-2011, 226 (77.7%) publications with the following research topics were identified: respiratory infections 3 (1.3%); parasites 8 (3.5%); diarrhoea 10 (4.4%); tuberculosis 10 (4.4%); human immunodeficiency virus (HIV) 11 (4.9%); multi-drug resistant bacteria (MDR) 18 (8.0%); polio 31 (13.7%); leishmania 31 (13.7%); malaria 46 (20.4%). From 2002-2011, 11 (4.9%) publications were basic science laboratory-based research studies. Between 2002-2011, 8 (3.5%) publications from Afghan institutions were identified. In conclusion, the internet-based database Pubmed can be consulted to collect data for guidance of infectious diseases research activity of low-income countries. The presented data suggest that infectious diseases research in Afghanistan is limited for respiratory infections research, has few studies conducted by Afghan institutions, and limited laboratory-based research contributions.

2017-01-01

A bibliometric analysis based on Scopus database was performed to identify the global research trends related to Supported Ionic Liquid Membranes (SILMs) during the time period from 1995 to 2015. This work tries to improve the understanding of the most relevant research topics and applications. The results from the analysis reveal that only after 2005 the research efforts focused on SILMs became significant, since the references found before that year are scarce. The most important research works on the four main application groups for SILMs defined in this work (carbon dioxide separation, other gas phase separations, pervaporation and liquid phase separations) were summarized in this paper. Carbon dioxide separation appeared as the application that has received by far the most attention according to the research trends during the analysed period. Comments about other significant applications that are gaining attention, such as the employment of SILMs in analytical tasks or their consideration for the production of fuel cells, have been included.

2012-01-01

To design a conceptual model on the transference of public health research results at the local, context level. Using systems thinking concepts, a soft systems approach (SSM) was used to analyse and solve what was perceived as a problem situation related to the transference of research results within Honduras public health system. A bibliometric analysis was also conducted to enrich the problem situation. Six root definitions were defined and modeled as relevant to the expressed problem situation. This led to the development of the conceptual model. The model obtained identified four levels of resolution as derived from the human activities involved in the transference of research results: 1) those of the researchers; 2) the information/documentation professionals; 3) health staff; and 4) the population/society. These actors/ clients and their activities were essential to the functioning of the model since they represent what the model is and does. SSM helped to design the conceptual model. The bibliometric analysis was relevant to construct the rich image of the problem situation.

Sleeping beauties in psychology: comparisons of "hits" and "missed signals" in psychological journals.

PubMed

Lange, Lydia L

2005-05-01

Scientific publications tend to be forgotten quickly. A few works, however, are still cited 100 years and more after their publication. The author used bibliometric methods to compare "hits" (works noticed by the scientific community soon after their publication) with "missed signals" (works that went unnoticed until much later) by investigating 2 psychological journals founded in the 1890s: Zeitschrift für Psychologie and Psychological Review. All articles that were published in either of these journals up to 1920 and cited more than 25 times in the Web of Science up to the year 2000 were considered for inclusion in the analysis. It emerged that hits corresponded more closely to the focus of scientific attention at the time of the publications than missed signals.

Bibliometrics as weapons of mass citation.

PubMed

Molinié, Antoinette; Bodenhausen, Geoffrey

2010-01-01

The allocation of resources for research is increasingly based on so-called 'bibliometrics'. Scientists are now deemed to be successful on the sole condition that their work be abundantly cited. This world-wide trend appears to enjoy support not only by granting agencies (whose task is obviously simplified by extensive recourse to bibliometrics), but also by the scientists themselves (who seem to enjoy their status of celebrities). This trend appears to be fraught with dangers, particularly in the area of social sciences, where bibliometrics are less developed, and where monographs (which are not taken into account in citation indexes) are often more important than articles published in journals. We argue in favour of a return to the values of 'real science', in analogy to the much-promised return to a 'real economy'. While economists may strive towards a more objective evaluation of the prospects of a company, a market, or an industrial sector, we scientists can only base our appraisal on a responsible practice of peer review. Since we fear that decision-takers of granting agencies such as the FNRS, CTI, EPFL, ETHZ, ANR, CNRS, NIH, NSF, DOE, etc. will be too busy to read our humble paper in Chimia, we appeal to scientists of all countries and disciplines to unite against the tyranny of bibliometrics.

2015-01-01

We have carried out a bibliometric study about the international scientific publications on clozapine. We have used the EMBASE and MEDLINE databases, and we applied bibliometric indicators of production, as Price’s Law on the increase of scientific literature. We also calculated the participation index (PI) of the different countries. The bibliometric data have also been correlated with some social and health data from the 12 most productive countries in biomedicine and health sciences. In addition, 5607 original documents dealing with clozapine, published between 1970 and 2013, were downloaded. Our results state non-fulfilment of Price’s Law, with scientific production on clozapine showing linear growth (r = 0.8691, vs. r = 0.8478 after exponential adjustment). Seven of the 12 journals with the highest numbers of publications on clozapine have an Impact Factor > 2. Among the countries generating clozapine research, the most prominent is the USA (PI = 24.32), followed by the UK (PI = 6.27) and Germany (PI = 5.40). The differences among countries on clozapine research are significantly related to economic variables linked to research. The scientific interest in clozapine remains remarkable, although after the application of bibliometric indicators of production, a saturation point is evident in the growth of scientific literature on this topic.

Plikus, Maksim V; Zhang, Zina; Chuong, Cheng-Ming

2006-01-01

Background Understanding research activity within any given biomedical field is important. Search outputs generated by MEDLINE/PubMed are not well classified and require lengthy manual citation analysis. Automation of citation analytics can be very useful and timesaving for both novices and experts. Results PubFocus web server automates analysis of MEDLINE/PubMed search queries by enriching them with two widely used human factor-based bibliometric indicators of publication quality: journal impact factor and volume of forward references. In addition to providing basic volumetric statistics, PubFocus also prioritizes citations and evaluates authors' impact on the field of search. PubFocus also analyses presence and occurrence of biomedical key terms within citations by utilizing controlled vocabularies. Conclusion We have developed citations' prioritisation algorithm based on journal impact factor, forward referencing volume, referencing dynamics, and author's contribution level. It can be applied either to the primary set of PubMed search results or to the subsets of these results identified through key terms from controlled biomedical vocabularies and ontologies. NCI (National Cancer Institute) thesaurus and MGD (Mouse Genome Database) mammalian gene orthology have been implemented for key terms analytics. PubFocus provides a scalable platform for the integration of multiple available ontology databases. PubFocus analytics can be adapted for input sources of biomedical citations other than PubMed.

2014-01-01

For patients suffering from rare diseases it is often hard to find an expert clinician. Existing registries rely on manual registration procedures and cannot easily be kept up to date. A prototype data collection system for discovering experts on rare diseases using MEDLINE has been successfully deployed. Initial manual analyses demonstrate proof of concept and deliver promising results. Examining the associations between authors, diseases and MeSH-Terms is expected to open up a variety of possibilities beyond expert discovery.

The relationship between metrics, such as the h-index, and the ability of researchers to generate funding has not been previously investigated in neurosurgery. This study was performed to determine whether a correlation exists between bibliometrics and National Institutes of Health (NIH) funding data among academic neurosurgeons. The h-index, m-quotient, g-index, and contemporary h-index were determined for 1225 academic neurosurgeons from 99 (of 101) departments. Two databases were used to create the citation profiles, Google Scholar and Scopus. The NIH Research Portfolio Online Reporting Tools Expenditures and Reports tool was accessed to obtain career grant funding amount, grant number, year of first grant award, and calendar year of grant funding. Of the 1225 academic neurosurgeons, 182 (15%) had at least 1 grant with a fully reported NIH award profile. Bibliometric indices were all significantly higher for those with NIH funding compared to those without NIH funding (P < .001). The contemporary h-index was found to be significantly predictive of NIH funding (P < .001). All bibliometric indices were significantly associated with the total number of grants, total award amount, year of first grant, and duration of grants in calendar years (bivariate correlation, P < .001) except for the association of m-quotient with year of first grant (P = .184). Bibliometric indices are higher for those with NIH funding compared to those without, but only the contemporary h-index was shown to be predictive of NIH funding. Among neurosurgeons with NIH funding, higher bibliometric scores were associated with greater total amount of funding, number of grants, duration of grants, and earlier acquisition of their first grant.

2014-06-01

Open access (OA) publications have changed the paradigm of dissemination of scientific research. Their benefits to low-income countries underline their value; however, critics question exorbitant publication fees as well as their effect on the peer review process and research quality. This study reports on the prevalence of OA publishing in orthopaedic research and compares benchmark citation indices as well as evidence quality derived from OA journals with conventional subscription based orthopaedic journals. All 63 orthopaedic journals listed in ISI's Web of Knowledge Journal Citation Report (JCR) were examined. Bibliometric data attributed to each journal for the year 2012 was acquired from the JCR. Studies that fulfilled the criteria of level I evidence were identified for each journal within PubMed. Individual journal websites were reviewed to identify their open access policy. A total of 38 (60.3 %) journals did not offer any form of OA publishing; however, 20 (31.7 %) hybrid journals were identified which offered authors the choice to publish their work as OA if a publication fee was paid. Only five (8 %) journals published all their articles as OA. There was variability amongst the different publication fees for OA articles. Journals that published OA articles did not differ from subscription based journals on the basis of 2012 impact factor, citation number, self citation proportion or the volume of level I evidence published (p > 0.05). OA journals are present in orthopaedic research, though in small numbers. Over a third of orthopaedic journals catalogued in the ISI Web of Knowledge JCR® are hybrid journals that provide authors with the opportunity to publish their articles as OA after a publication fee is paid. This study suggests equivalent importance and quality of articles between OA and subscription based orthopaedic journals based on bibliometric data and the volume of level I evidence produced. Orthopaedic researchers must recognize the potential benefits of OA publishing and its emerging presence within the field. Further examination and consensus is required in orthopaedic research to generate an OA system that is robustly regulated and maintains research quality.

Mapping patient safety: a large-scale literature review using bibliometric visualisation techniques.

Rodrigues, S P; van Eck, N J; Waltman, L; Jansen, F W

2014-03-13

The amount of scientific literature available is often overwhelming, making it difficult for researchers to have a good overview of the literature and to see relations between different developments. Visualisation techniques based on bibliometric data are helpful in obtaining an overview of the literature on complex research topics, and have been applied here to the topic of patient safety (PS). On the basis of title words and citation relations, publications in the period 2000-2010 related to PS were identified in the Scopus bibliographic database. A visualisation of the most frequently cited PS publications was produced based on direct and indirect citation relations between publications. Terms were extracted from titles and abstracts of the publications, and a visualisation of the most important terms was created. The main PS-related topics studied in the literature were identified using a technique for clustering publications and terms. A total of 8480 publications were identified, of which the 1462 most frequently cited ones were included in the visualisation. The publications were clustered into 19 clusters, which were grouped into three categories: (1) magnitude of PS problems (42% of all included publications); (2) PS risk factors (31%) and (3) implementation of solutions (19%). In the visualisation of PS-related terms, five clusters were identified: (1) medication; (2) measuring harm; (3) PS culture; (4) physician; (5) training, education and communication. Both analysis at publication and term level indicate an increasing focus on risk factors. A bibliometric visualisation approach makes it possible to analyse large amounts of literature. This approach is very useful for improving one's understanding of a complex research topic such as PS and for suggesting new research directions or alternative research priorities. For PS research, the approach suggests that more research on implementing PS improvement initiatives might be needed.

Using bibliometrics, we analyzed the research status of immune checkpoint blockade (ICB, a popular tumor immunotherapy method represented by antibodies targeted CTLA-4 and PD-1/PD-L1) in tumor immunotherapy in China during the past 2 decades. Articles in Science Citation Index Expanded (SCI-EXPANDED), patents in Thomson Innovation, and drugs in Cortellis Competitive Intelligence in the field of ICB for tumor immunotherapy from 1996 to 2015 were the subjects of bibliometric analysis. Using database-attached software and Excel, quantitative analyses were performed including examination of the number of documents, citation frequency, h-index, key projects, quantity of publications, public patents, and status of new drug research. The number of publications from 1996 to 2015 in the field of ICB for tumor immunotherapy that came out of China was 380, which was 14.3% of the total publications worldwide and was second only to that of the USA. In the past decade, China has rapidly increased the number of publications and patents in this field. However, indicators of publication influence, such as citation frequency and h-index, were far behind other advanced countries. In addition, the total number of patents in China was much lower than that of the USA. China has introduced 5 drugs for ICB that are being developed for the healthcare market. Tumor immunotherapy research such as ICB in China has developed rapidly with increasing influence in the last 2 decades. However, there is still a relatively large gap compared with the USA. It is expected that China will have greater influence on tumor immunotherapy research in the near future.

Babineau, Matthew; Fischer, Christopher; Volz, Kathryn; Sanchez, Leon D

2014-05-01

The number of publications and how often these have been cited play a role in academic promotion. Bibliometrics that attempt to quantify the relative impact of scholarly work have been proposed. The h-index is defined as the number (h) of publications for an individual that have been cited at least h times. We calculated the h-index and number of publications for academic emergency physicians at the rank of professor. We accessed the Society for Academic Emergency Medicine professor list in January of 2012. We calculated the number of publications through Web of Science and PubMed and the h-index using Google scholar and Web of Science. We identified 299 professors of emergency medicine. The number of professors per institution ranged from 1 to 13. Median h-index in Web of Science was 11 (interquartile range [IQR] 6-17, range 0-51), in Google Scholar median h-index was 14 (IQR 9-22, range 0-63) The median number of publications reported in Web of Science was 36 (IQR 18-73, range 0-359. Total number of publications had a high correlation with the h-index (r=0.884). The h-index is only a partial measure of academic productivity. As a measure of the impact of an individual's publications it can provide a simple way to compare and measure academic progress and provide a metric that can be used when evaluating a person for academic promotion. Calculation of the h-index can provide a way to track academic progress and impact. [West J Emerg Med. 2014;15(3):290-292.].

2016-01-01

The study of scientific production is a good indicator of the progress in research and knowledge generation. Bibliometrics is a scientific discipline that uses a set of indicators to quantitatively express the bibliographic characteristics of scientific publications. The scientific literature on the epidemiology of intestinal parasites in Argentina is scattered in numerous sources, hindering access and visibility to the scientific community. Our purpose was to perform a quantitative, bibliometric study of the scientific literature on intestinal parasites in humans in Argentina published in the period 1985-2014. This bibliometric analysis showed an increase in the number of articles on intestinal parasites in humans in Argentina published over the past 30 years. Those articles showed a collaboration index similar to that of the literature, with a high index of institutionality for national institutions and a very low one for international collaboration. The original articles were published in scientific journals in the American Continent, Europe and Asia. The use of bibliometric indicators can provide a solid tool for the diagnosis and survey of the research on epidemiology of intestinal parasites and contributes to the dissemination and visibility of information on the scientific production developed in Argentina.

2017-10-25

Background Bibliometric science employs statistical and quantitative analyses to analyse the scholarly impact and characteristics of publications within a research field. The present study was initiated to analyse and quantify the 100 most often cited papers in glaucoma research. Materials and Methods The databases of the Institute for Scientific Information were utilised for the identification of articles published from 1900 to December 2016. All glaucoma articles were identified that had been published in 109 relevant journals and which had been cited at least 200 times. The top 100 articles were selected for further analysis of authorship, source journal, number of citations, citation rate, geographic origin, article type, and level of evidence. Results The publication dates of the 100 most often cited articles ranged from 1966 to 2011, with the greatest number of articles published in the 1990s. Citations per article ranged from 258 to 1908. All articles were published in 18 of the 109 journals. The leading countries of origin were the U. S. A., followed by the U. K. The study focussed on two main clinical articles (diagnostics; epidemiology) and basic research articles. The number of citations per article was greatest for articles published in the 2000s. Most articles provided level III evidence, followed by levels I and II. Conclusion The majority of the most cited articles were published in three of the top-ranked journals. Most clinical articles dealt with epidemiology and diagnostics. Individuals who authored multiple articles in the list often focussed on one of these two areas. Most studies were conducted in the U. S. A. and presented level III clinical outcomes. This indicates that even studies with small case series or cohort studies can attract attention.

"Publish or Perish" as citation metrics used to analyze scientific output in the humanities: International case studies in economics, geography, social sciences, philosophy, and history.

Baneyx, Audrey

2008-01-01

Traditionally, the most commonly used source of bibliometric data is the Thomson ISI Web of Knowledge, in particular the (Social) Science Citation Index and the Journal Citation Reports, which provide the yearly Journal Impact Factors. This database used for the evaluation of researchers is not advantageous in the humanities, mainly because books, conference papers, and non-English journals, which are an important part of scientific activity, are not (well) covered. This paper presents the use of an alternative source of data, Google Scholar, and its benefits in calculating citation metrics in the humanities. Because of its broader range of data sources, the use of Google Scholar generally results in more comprehensive citation coverage in the humanities. This presentation compares and analyzes some international case studies with ISI Web of Knowledge and Google Scholar. The fields of economics, geography, social sciences, philosophy, and history are focused on to illustrate the differences of results between these two databases.

We used bibliometric analysis methodology in the expanded Science Citation Index to identify highly-cited electrocardiogram (ECG)-related articles with total citations (TC2012) exceeding 100 from the publication year to 2012. Web of Science search tools were used to identify the highly-cited articles. The aspects analyzed for highly cited publications included effect of time on citation analysis, journals and Web of Science categories, number of authors per publication, originating institutions and countries, total citation and total citation per year life cycles of articles (C2012) and research hotspots. Results showed that a total of 467 electrocardiogram-related publications were regarded as the highly-cited publications. TC2012 ranged from 101 to 2879, with 215 as the average number of citations. No highly-cited publications have emerged yet during the first two years of the present 2010 Decade. All 11 countries and institutions originating highly-cited ECG-related publications were developed countries, USA in 9 of them. Four subject categories were identified as hotspots by total citations TC2012 and C2012: atrial fibrillation, long QT syndrome, angina and myocardial infarction, and risk factor analysis and health evaluation.

A comprehensive review of National research policy papers issued over the past 6 years was carried out. A set of problems concerning the quality of predicted values of some bibliometric indicators reflecting the level of research performance and publication activity that were declared in governmental documents was discussed. Basic metrics of scientific performance that should be required to achieve the goals declared in the recent governmental policy papers including President's Executive Order No 599 of May 7, 2012 (increasing the share of Russian researchers' publications in the total number of publications in international scientific journals indexed in the Web of Science up to 2.44% in 2015). Taking into account the current structure of modern global science in which papers in biomedical subjects make up for approximately one third of the total world scientific output, it becomes obvious how difficult is the governmental task set up to the researchers--to double the number of journal publications indexed in Web of Science in the short-term period of the nearest three years. The priorities and reasonable goal-oriented efforts to meet the targets are proposed in the paper.

The aim of this study was to quantify changes in the national contributions to research related to posttraumatic stress disorder (PTSD) from 1983 through 2002. Using the Web of Science database (Thomson Scientific, Philadelphia, PA), we classified articles according to the year of publication and the country of the authors. The number of publishing countries increased from 7 between 1983 and 1987 to 39 between 1998 and 2002. Meanwhile, the U.S. output share declined from 87.6% in the first period to 62.4%. Although the number of countries publishing on PTSD has steadily increased, research is still dominated qualitatively and quantitatively by developed countries. These findings suggest a growing international acceptance of this diagnostic category. However, the immaturity of PTSD research is demonstrated by the concentration of publications in a few countries.

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

2016-11-01

The number of citations an article receives has been used as a marker of its influence within a surgical specialty. Currently, there is limited citation analysis in oral and maxillofacial trauma surgery. The purpose of this study was to determine the 100 most cited articles in facial trauma surgery and their characteristics. Articles were identified from the Science Citation Index of the Institute for Scientific Information using the Thomson Reuters Web of Science search engine. All articles until 2015 were included. Then, the 100 most cited articles were assessed for title, author, journal, country of origin, and number of citations. A citation index (number of citations received per year) also was calculated. The 100 most cited articles in facial trauma received 9,933 citations (range, 66 to 297). They were published from 1942 through 2008, with 1990 through 1999 being the commonest decade. Articles were cited on average 4.6 times per year. Articles were published in 28 different journals, with impact factors ranging from 0.94 to 35.3. Most articles were observational research studies. These findings reflect the attention that articles have received during the past half century in oral and maxillofacial trauma research, shedding light on often-read articles in this field. In addition to current bibliometric indices, it could provide a useful evidence base for facial surgeons, represent key educational material for aspiring trainees, and be used to help guide future research efforts.

Background Inappropriate use of drugs is commonly observed in health care system throughout the world especially in developing countries. The consequences of irrational use of drugs are enormous for patients and communities. Proper interventions would have important financial and public health benefits. Several studies have been performed about rational use of drugs in Iran. Objective The objective of this study was to assess scientific output on rational use of drugs in Iran using a bibliometric analysis of publications. Methods A systematic search was conducted for finding all papers (English and Persian) using Pubmed, Web of Science, Google Scholar, CINAHL, Proquest, International Pharmaceutical Abstract and Persian databases including SID, Iran Medex and MagIran. Retrieved articles were categorized by research topics and year of publication. Impact Factor of the journals, citation analysis of first authors, most cited topics and average citations per item were analyzed. Results A total of 668 articles were retrieved from all search engines after excluding irrelevant, 466 articles were included in the review. Number of publications increased dramatically after 2001(more than 10 times). Evaluation of prescribing pattern (15%), self-medication (11.3%) and adverse drug reaction (9.1%) were among the most studied topics. From the total of 165 journals, 60 of them had Impact factors and 125 articles were published in these journals. Antimicrobial resistance and adverse drug reaction were the most cited topic. Conclusions Publication of articles on rational use of drugs research in Iran has undergone an important increase during last decade. Further analysis of research outputs is necessary to achieve rational use of medicines goal. PMID:24155848

The aim of this study was to perform a bibliometric analysis of EPI-SCAN and IBERPOC studies using the Science Citation Index and Scopus databases, and to determine the overall impact with the impact of smoking on IBERPOC as a secondary objective. A general searching was conducted in Science Citation Index-Expanded through the Web of Science (WoS) (Thomson Reuters) platform and Scopus on 23 March 2015. The search strategy included the terms "iberpoc" OR "episcan" was performed on 15 October 2015. A total of 24 publications were obtained; 13 from IBERPOC study (9 on "COPD" and 4 for "tobacco"), with 11 from the EPI-SCAN (All COPD) study. A total of 841 WoS citations were obtained (445 IBERPOC [99 of tobacco]), and 1,442 from Scopus (963 IBERPOC [144 tobacco]). The theme "tobacco" contributed with 22.24% and 14.95% of total citations in WoS and Scopus, respectively to the IBERPOC study. It was found that Scopus citations were newer, and a similar impact from both WoS studies was detected, although the IBERPOC impact was greater in Scopus. Collaborative networks of institutions and authors of both studies were identified. There is an important productivity and impact of both studies. Scopus citations are newer than those in WoS. The "tobacco" variable added IBERPOC impact and visibility. There was high density, accessibility, and cohesion in collaborative networks of both studies.

The scientific contributions (publications) and international influence (citations) from authors providing the palliative care (PC)-related literature has a limited number of bibliometric reports. We aimed to analyze PC-related literature using the Institute for Scientific Information Web of Science (WoS) database. WoS database was used to retrieve publications with the following key words with title: "palliative care" OR "End of Life care" OR "terminal care.". The statistical analysis of the documents published during 2001 to 2016 was performed. The quantity and quality of research were assessed by the number of total publications and citation analysis. In addition, we also analyzed whether there were possible correlations between publication and socioeconomic factors. The total research output was 6273 articles for PC. There was a 3-fold increase in the number of publications during the period and strong correlation between the year and number of PC-related publications ( R 2 = .96). The United States took a leading position in PC research (2448, 39.0%). The highest average citations was reported for the Norway (21.8). Australia had gained the highest productive ability in PC research (24.9 of articles per million populations). The annual impact factor rose progressively with time and increased 1.13 to 2.24 from 2003 to 2016. The number of publications correlated with gross domestic product ( r = .74; P < .001). The United States and United Kingdom contributed most of the publications, but some East Asian countries also had a great performance. According to the socioeconomic factors, the publication capacity of top 20 countries is correlated with their economic scale.

Smith, Derek R; Hazelton, Michael

2008-12-01

Bibliometric research has risen in popularity during recent years and an increasing number of investigations now have examined the nursing literature. Our article provides a comprehensive overview of citation-based research in the nursing profession, as well as a discussion of bibliometrics, journal impact factors, and international publishing trends. The debate on evidence-based practice and its potential influence and relevance for nursing scholars is also covered. Although journal performance indicators are, no doubt, important for the contemporary nursing academic, it is the core research skills and attributes that nursing scholars, academics, and educators will need to consider more carefully in future if the next generation of professional nurse researchers is to truly flourish.

Tracking the emergence of synthetic biology.

Shapira, Philip; Kwon, Seokbeom; Youtie, Jan

2017-01-01

Synthetic biology is an emerging domain that combines biological and engineering concepts and which has seen rapid growth in research, innovation, and policy interest in recent years. This paper contributes to efforts to delineate this emerging domain by presenting a newly constructed bibliometric definition of synthetic biology. Our approach is dimensioned from a core set of papers in synthetic biology, using procedures to obtain benchmark synthetic biology publication records, extract keywords from these benchmark records, and refine the keywords, supplemented with articles published in dedicated synthetic biology journals. We compare our search strategy with other recent bibliometric approaches to define synthetic biology, using a common source of publication data for the period from 2000 to 2015. The paper details the rapid growth and international spread of research in synthetic biology in recent years, demonstrates that diverse research disciplines are contributing to the multidisciplinary development of synthetic biology research, and visualizes this by profiling synthetic biology research on the map of science. We further show the roles of a relatively concentrated set of research sponsors in funding the growth and trajectories of synthetic biology. In addition to discussing these analyses, the paper notes limitations and suggests lines for further work.

Over the past two decades, the use of telemedicine as a way to provide medical services has grown as communication technologies advance and patients seek more convenient ways to receive care. Because developments within this field are still rapidly evolving, identifying trends within telemedicine literature is an important task to help delineate future directions of telemedicine research. In this study, we analyzed 7960 telemedicine-related publication records found in the Science Citations Index - Expanded database between 1993 and 2012. Bibliometric analyses revealed that while the total growth in telemedicine literature has been significant in the last twenty years, the publication activity per country and over time has been variable. While the United States led the world in the cumulative number of telemedicine publications, Norway ranked highest when we ordered countries by publications per capita. We also saw that the growth in the number of publications per year has been inconsistent over the past two decades. Our results identified that neuroscience neurology and nursing as two fields of research in telemedicine that have seen considerable growth in interest in this field, and are poised to be the focus of research activity in the near future.

To perform a bibliometric analysis of theses and dissertations on prematurity in the Capes database from 1987 to 2009. This is a descriptive study that used the bibliometric approach for the production of indicators of scientific production. Operationally, the methodology was developed in four steps: 1) construction of the theoretical framework; 2) data collection sourced from the abstracts of theses and dissertations available in the Capes Thesis Database which presented the issue of prematurity in the period 1987 to 2009; 3) organization, processing and construction of bibliometric indicators; 4) analysis and interpretation of results. Increase in the scientific literature on prematurity during the period 1987 to 2009; production is represented mostly by dissertations; the institution that received prominence was the Universidade de São Paulo. The studies are directed toward the low birth weight and very low birth weight preterm newborn, encompassing the social, biological and multifactorial causes of prematurity. There is a qualified, diverse and substantial scientific literature on prematurity developed in various graduate programs of higher education institutions in Brazil.

Bibliometric analysis of literature on female genital mutilation: (1930 - 2015).

Sweileh, Waleed M

2016-10-10

Female genital mutilation/cutting (FGM/C) is a common harmful traditional practice in many communities in Africa and to a lesser extent in Middle East and other regions in the world. In order to better understand publishing on this topic, we conducted a bibliometric study on FGM/C. Bibliometric analyses can be used as an indicator of the extent of interaction of researchers, health authorities, and communities with a particular health issue. Scopus database was used to retrieve data on FGM/C. Keywords used were "female genital mutilation", "female genital circumcision", "female genital cutting" and "female circumcision". Specifically, the number of publications, top productive countries and institutions, highly cited articles, citation analysis, co-authorships, international collaboration, role of African countries, top active authors, and journals involved in publishing articles on FGM/C were reviewed and analyzed. We indirectly assessed the impact of publications using total number of citations received, average number of citations per article, Hirsch-index, percentage of highly cited articles, and journal's impact factor. One thousand and thirty-five publications on FGM/C were retrieved. The h-index of retrieved articles was 37. A steep rise in number of publications was noticed in mid-1990s and again in 2012. More than half of retrieved articles were published from 2006 - 2015. A total of 65 countries contributed. The top ten productive countries included ones from Northern America, Europe and Africa. Nigeria and Egypt were the most active African countries in FGM/C publications. At least nine African academic institutions were actively involved on FGM/C publications. Articles on FGM/C that received the highest number of citations were those that focused on negative physical and psychosexual consequences of FGM/C. Journal topic areas were obstetrics/gynecology, public health, and psychological sociology. Collaboration between African and European countries on FGM/C research was evident. Bibliometric analysis reveals that research publications on FGM/C have been increasing since the l970s, with collaboration between African and Western countries, and articles are being published in higher impact journals, not only obstetrics, but also public health and social sciences. FGM/C research can be helpful to international health agencies and governments not only to document negative outcomes, but also to identify best practices, and to note gaps in implementation and practice.

Bibliometrics are a set of methods, which can be used to analyze academic literature quantitatively and its changes over time. The objectives of this study were 1) to evaluate trends related to academic performance of dental journals from 2003 to 2012 using bibliometric indices, and 2) monitor the changes of the five dental journals with the highest and lowest impact factor (IF) published in 2003. Data for the subject category "Dentistry, Oral Surgery & Medicine" was retrieved from the Journal Citation Reports (JCR) published from 2003 to 2012. Linear regressions analysis was used to determine statistical trends over the years with each bibliometric indicator as the dependent variable and the JCR year as the predictor variable. Statistically significant rise in the total number of dental journals, the number of all articles with the steepest rise observed for research articles, the number of citations and the aggregate IF was observed from 2003 to 2012. The analysis of the five top and five bottom-tire dental journals revealed a rise in IF however, with a wide variation in relation to the magnitude of this rise. Although the IF of the top five journals remained relatively constant, the percentile ranks of the four lowest ranking journals in 2003 increased significantly with the sharpest rise being noted for the British Journal of Oral & Maxillofacial Surgery. This study revealed significant growth of dental literature in absolute terms, as well as upward trends for most of the citation-based bibliometric indices from 2003 to 2012. PMID:25781486

Biblio-MetReS: A bibliometric network reconstruction application and server

PubMed Central

2011-01-01

Background Reconstruction of genes and/or protein networks from automated analysis of the literature is one of the current targets of text mining in biomedical research. Some user-friendly tools already perform this analysis on precompiled databases of abstracts of scientific papers. Other tools allow expert users to elaborate and analyze the full content of a corpus of scientific documents. However, to our knowledge, no user friendly tool that simultaneously analyzes the latest set of scientific documents available on line and reconstructs the set of genes referenced in those documents is available. Results This article presents such a tool, Biblio-MetReS, and compares its functioning and results to those of other user-friendly applications (iHOP, STRING) that are widely used. Under similar conditions, Biblio-MetReS creates networks that are comparable to those of other user friendly tools. Furthermore, analysis of full text documents provides more complete reconstructions than those that result from using only the abstract of the document. Conclusions Literature-based automated network reconstruction is still far from providing complete reconstructions of molecular networks. However, its value as an auxiliary tool is high and it will increase as standards for reporting biological entities and relationships become more widely accepted and enforced. Biblio-MetReS is an application that can be downloaded from http://metres.udl.cat/. It provides an easy to use environment for researchers to reconstruct their networks of interest from an always up to date set of scientific documents. PMID:21975133

Ismail, Sharif; Nason, Edward; Marjanovic, Sonja; Grant, Jonathan

2012-01-01

Abstract Bibliometric analysis is an increasingly important part of a broader “toolbox” of evaluation methods available to research and development (R&D) policymakers to support decision-making. In the US, UK and Australia, for example, there is evidence of gradual convergence over the past ten years towards a model of university research assessment and ranking incorporating the use of bibliometric measures. In Britain, the Department of Health (England) has shown growing interest in using bibliometric analysis to support prospective R&D decision-making, and has engaged RAND Europe's expertise in this area through a number of exercises since 2005. These range from the macro-level selection of potentially high impact institutions, to micro-level selection of high impact individuals for the National Institute for Health Research's faculty of researchers. The aim of this study is to create an accessible, “beginner's guide” to bibliometric theory and application in the area of health R&D decision-making. The study also aims to identify future directions and possible next steps in this area, based on RAND Europe's work with the Department of Health to date. It is targeted at a range of audiences, and will be of interest to health and biomedical researchers, as well as R&D decision-makers in the UK and elsewhere. The study was completed with funding support from RAND Europe's Health R&D Policy Research Unit with the Department of Health. PMID:28083218

Research productivity plays a significant role in academic promotions. Currently, various bibliometric measures utilizing citation counts are used to judge an author's work. With increasing numbers of journals, numbers of open access publications, ease of online submission, and expedited indexing of accepted manuscripts, it is plausible that an author could influence his/her own bibliometric measures through self-citation. The purpose of this study was to determine the impact of self-citation in academic plastic surgery. A cohort of full-time academic plastic surgeons was identified from 9 U.S. plastic surgery training programs. For all included faculty, academic rank was retrieved from department/division websites, and bibliometric measures were assessed using a subscription bibliographic citation database (Scopus, Reed Elsevier, London, UK). Bibliometric measures included the Hirsch index (h-index, the number of publications h which are cited ≥ h times), total number of publications, and total number of citations. The h-index and total number of citations were collected with and without self-citations. Percent changes in the h-index and total citations were calculated after removal of self-citations and compared across academic ranks and levels of research productivity (total publications, h-index, and total citations). The study cohort consisted of 169 full-time academic plastic surgeons. The h-index and total citations experienced decreases of 2.8 ± 5.0% (P < 0.0001) and 4.5 ± 4.6% (P < 0.0001), respectively, after correction for self-citation. More than half of the cohort (n = 113, 67%) did not experience a change in the h-index after removal of self-citations. These decreases did not vary across academic rank. Surgeons who self-cited at rates greater than 5% were 9.8 times more likely (95% confidence interval, 4.5-21.9; P < 0.001) to have their h-index change as a result of self-citation (after adjusting for academic rank). There were weak correlations between percent decreases in the h-index and total citations and various biblimoteric measures (total publications, h-index, total citations; r < 0.32). Self-citation has a minor impact on common bibliometric measures in academic plastic surgery. The influence of self-citation is consistent across academic ranks and increasing levels of bibliometric measures, suggesting that authors are not manipulating the system with increasing experience.

We conducted a bibliometric and content analysis of research on health inequalities produced in Latin American and Caribbean countries. In our bibliometric analysis (n = 576), we used indexed material published between 1971 and 2000. The content analysis (n = 269) covered the period 1971 to 1995 and included unpublished material. We found recent rapid growth in overall output. Brazil, Chile, and Mexico contributed mostly empirical research, while Ecuador and Argentina produced more conceptual studies. We found, in the literature reviewed, a relative neglect of gender, race, and ethnicity issues. We also found remarkable diversity in research designs, however, along with strong consideration of ecological and ethnographic methods absent in other research traditions. PMID:14652329

Fishing for gaps in science: a bibliographic analysis of Brazilian freshwater ichthyology from 1986 to 2005.

PubMed

Azevedo, P G; Mesquita, F O; Young, R J

2010-06-01

To investigate Brazilian freshwater ichthyology, from 1986 to 2005, a bibliometric analysis was conducted using abstracts downloaded from The Web of Science database searching for the keywords 'fish', 'pisces', 'teleostei' and the address field having the word 'Brazil'. The results of this study showed that Brazilian freshwater ichthyology publications have been increasing during the study period. This process is a consequence of a series of investments that the Brazilian Government has made. Furthermore, data analyses identified scientific areas where there was a lack of scientific knowledge (e.g. studies of species threatened with extinction and certain hydrologic basins). Research institutions from the north-east and northern region of Brazil had the lowest participation in scientific productivity, which was a reflection of their regions poorer economic situation. This study showed that scientific productivity in Brazilian ichthyology was a direct reflection of state investment in research. Furthermore, data in this study follow expected statistical probabilities, for example, fishes from the most diverse families were the most studied. Thus, the study shows that great progress has been made by Brazilian ichthyologists in the last 20 years; however, due to the mega diversity of fishes in Brazil, much remains to be done if many species are to become known to science and to be saved from extinction. This it seems will depend on continued and further investment by Brazilian Government funding agencies, as Brazilian ichthyologists have demonstrated their capacity to generate high quality information about their study species.

To identify global research trends in the use of nerve conduits for peripheral nerve injury repair. Numerous basic and clinical studies on nerve conduits for peripheral nerve injury repair were performed between 2002-2011. We performed a bibliometric analysis of the institutions, authors, and hot topics in the field, from the Web of Science, using the key words peripheral nerve and conduit or tube. peer-reviewed published articles on nerve conduits for peripheral nerve injury repair, indexed in the Web of Science; original research articles, reviews, meeting abstracts, proceedings papers, book chapters, editorial material, and news items. articles requiring manual searching or telephone access; documents not published in the public domain; and several corrected papers. (a) Annual publication output; (b) publication type; (c) publication by research field; (d) publication by journal; (e) publication by funding agency; (f) publication by author; (g) publication by country and institution; (h) publications by institution in China; (i) most-cited papers. A total of 793 publications on the use of nerve conduits for peripheral nerve injury repair were retrieved from the Web of Science between 2002-2011. The number of publications gradually increased over the 10-year study period. Articles constituted the main type of publication. The most prolific journals were Biomaterials, Microsurgery, and Journal of Biomedical Materials Research Part A. The National Natural Science Foundation of China supported 27 papers, more than any other funding agency. Of the 793 publications, almost half came from American and Chinese authors and institutions. Nerve conduits have been studied extensively for peripheral nerve regeneration; however, many problems remain in this field, which are difficult for researchers to reach a consensus.

Santin, Dirce M; Vanz, Samile A S; Stumpf, Ida R C

2016-03-01

This article analyzes the existing collaboration networks in the Brazilian scientific output in Evolutionary Biology, considering articles published during the period from 2000 to 2012 in journals indexed by Web of Science. The methodology integrates bibliometric techniques and Social Network Analysis resources to describe the growth of Brazilian scientific output and understand the levels, dynamics and structure of collaboration between authors, institutions and countries. The results unveil an enhancement and consolidation of collaborative relationships over time and suggest the existence of key institutions and authors, whose influence on research is expressed by the variety and intensity of the relationships established in the co-authorship of articles. International collaboration, present in more than half of the publications, is highly significant and unusual in Brazilian science. The situation indicates the internationalization of scientific output and the ability of the field to take part in the science produced by the international scientific community.

2018-06-01

This article provides an overview and synthesis of the 100 most cited healthcare simulation publications to provide insight into the articles that have shaped current knowledge and practice. Searches of the Scopus and Web of Science databases were conducted in July 2017. Most articles were concerned with medical education and training (86%) and were most often published in surgical journals (33%). Manikins (20%), standardized patients (16%), inanimate part-task trainers (16%), fully simulated environments (17%), and virtual reality part-task trainers (14%) were the most commonly featured types of simulators. Healthcare simulation research has matured and grown during the preceding decades. There has been a move away from research questions focused on "does simulation work?" to an assessment of the conditions under which simulation is most effective. It is hoped that providing an overview of highly cited works will help identify topics for further research.

2012-02-01

This paper provides a map of the scientific productivity of authors affiliated to a Spanish institution and who have addressed one of the most important current topics in schizophrenia: The study of cognitive performance. A search of the Web of Science yielded 125 articles that met the inclusion criteria. In order to provide a comprehensive overview of scientific productivity, we examine several bibliometric indicators, concerning both productivity and impact or visibility. The analysis also focuses on qualitative aspects of key theoretical importance, such as the kinds of cognitive functions that are most often assessed and the tests most widely used to evaluate them in clinical practice. The study shows that interest in the subject of cognitive function in schizophrenia has increased considerably in Spain since the beginning of this century. The results also highlight the need to standardize the type of tests to be used in the cognitive assessment of patients with schizophrenia.

A bibliometric study of peer-reviewed scientific publications on atypical antipsychotic drugs (AADs) from Italy is herein presented. We selected the documents from Scopus database. We applied several bibliometric indicators of production and dispersion, including Price’s Law about the increase of scientific literature, and Bradford’s Law. We also calculated the participation index across different countries. The bibliometric data have also been correlated with some social and health data sourcing in Italy, such as total per capita expenditure on health and gross domestic expenditure. A total of 2949 original documents were published within the period 1972-2015. Our results state fulfilment of Price’s Law, with scientific production showing exponential growth (r=0.901, as against an r=0.838 after linear adjustment). The drugs most widely studied were clozapine (257 documents), risperidone (179), and olanzapine (172). Stratification into Bradford zones yielded a nucleus represented by the Journal of Clinical Psychopharmacology and Rivista di Psichiatria (58 articles, each one). A total of 1091 different journals were evaluated. The publications on AADs in Italy have undergone exponential growth over the studied period, which is in line with the progressively burgeoning on novel AAD releases. No evidence of saturation point was observed.

Bibliometrics involves the statistical analysis of the publications in a specific discipline or subject area. A bibliometric analysis of the occupational therapy refereed literature is needed. A bibliometric analysis was completed of the occupational therapy literature from 1991-2014, indexed in the Science Citation Index-Expanded or the Social Sciences Citation Index. Publications were searched by title, abstract, keywords, and KeyWords Plus. Total number of article citations, citations per journal, and contributions per country, individual authors, and institution were calculated. 5,315 occupational therapy articles were published in 821 journals. It appears that there is a citation window of an approximate 10-year period between the time of publication and the peak number of citations an article receives. The top three most highly cited articles were published in Developmental Medicine and Child Neurology, JAMA, and Lancet. AJOT, BJOT and AOTJ published the largest number of occupational therapy articles with the United States, Australia, and Canada producing the highest number of publications. McMaster University, the University of Queensland, and the University of Toronto were the institutions that published the largest number of occupational therapy journal articles. The occupational therapy literature is growing and the frequency of article citation is increasing.

Citation analysis is an established bibliometric method which catalogues papers according to the number of times they have been referenced. It is believed that the total number of citations an article receives reflects its importance among its peers. Never before has a bibliometric analysis been performed in the area of Cleft Lip and Palate. Our citation analysis creates a comprehensive list of the 50 most influential papers in this field. Journals specializing in Cleft Palate, Craniofacial, Plastic Surgery, Maxillofacial Surgery, Aesthetics and Radiology were searched to establish which articles most enriched the specialty over the past 70 years. The results show an interesting collection of papers which reveal developing trends in surgical techniques. These landmark papers mould and influence management and decision-making today.

Progressive and self-limiting neurodegenerative disorders in Africa: a new prominent field of research led by South Africa but without strong health policy.

Poreau, Brice

2016-01-01

Neurodegenerative disorders are involved in mortality and morbidity of every country. A high prevalence is estimated in Africa. Neurodegenerative disorders are defined by a progressive or self-limiting alteration of neurons implied in specific functional and anatomical functions. It encompasses a various range of clinical disorders from self-limiting to progressive. Focus on public health policies and scientific research is needed to understand the mechanisms to reduce this high prevalence. We use bibliometrics and mapping tools to explore the area studies and countries involved in scientific research on neurodegenerative disorders in Africa. We used two databases: Web of Science and Pubmed. We analyzed the journals, most cited articles, authors, publication years, organizations, funding agencies, countries and keywords in Web of Science Core collection database and publication years and Medical Subject Headings in Pubmed database. We mapped the data using VOSviewer. We accessed 44 articles published between 1975 and 2014 in Web of Science Core collection Database and 669 from Pubmed database. The majority of which were after 2006. The main countries involved in research on neurodegenerative disorders in Africa the USA, the United Kingdom, France and South Africa representing the main network collaboration. Clinical neurology and Genetics hereditary are the main Web of Science categories whereas Neurosciences and Biochemistry and Molecular Biology are the main Web of Science categories for the general search "neurodegenerative disorders" not restrained to Africa. This is confirmed by Medical Subject Headings analysis from Pubmed with one more area study: Treatment. Neurodegenerative disorders research is leaded by South Africa with a network involving the USA, the UK, as well as African countries such Zambia. The chief field that emerged was on patient and hereditary as well as treatment. Public health policies were lacking fields in research whereas prevalence is estimated to be important in every country. New 17 sustainable development goals of the United Nations could help in this way.

AIM. Bibliometric analysis of neuropaediatrics articles published in Revista de Neurologia and Anales de Pediatria between 2000 and 2009. MATERIALS AND METHODS. We selected neuropaediatrics articles published in two journal during the last decade (n = 1,085). We investigated authorship, topic and bibliography, to calculate indices of isolation, Price, collaboration, productivity, transience and self-citations. Analyze citations received by Web of Knowledge (WOK): articles cited, sometimes cited and h-index. RESULTS. 1,085 articles were analyzed, 255 published in Anales de Pediatria (9.4% of the total in that period) and 830 in Revista de Neurologia (21.7% total). The collaboration index was 4.3. The 89.7% of the authors were medical care (96% hospital staff, 0,8% of primary care staff and 2.9% of both). The 11.9% ??of the articles were collaborative between regions and the 26% came from foreign centers. The originals were 29.8% (80.8% descriptive observational studies, analytical 18.3% and 0.8% clinical trials). The most frequent topics were paroxysmal disorders (15.9%) and developmental, learning and behavioral disorders (15%). The average number of citations per article was 27.6, with an isolation rate of 13.4% and a Price index of 41.7%. The profile of the articles published in both journals is different, finding significant differences in almost all parameters analyzed. According WOK, the 255 items of Anales de Pediatria have received 40 citations and h-index of 3 and the 830 Revista de Neurologia 2,234 citations with h-index of 13. CONCLUSIONS. There are differences in the pediatric neurology publications between the two magazines with more international projection of Revista de Neurologia.

The aim of this study was to assess the scientific output of Spanish universities that offer a bachelor's degree in dentistry through the use of various bibliometric indicators. A total of 21 universities offered a bachelor's degree in dentistry in academic year 2016-2017. The search for papers published by authors associated with these institutions was carried out using the selection of journals listed in the Journal Citation Reports (JCR) and the Web of Knowledge database for the period 1986-2017. On the basis of these data, we determined the output, the h-, g- and hg-indexes, the most productive authors, international collaborations, and the most relevant journals. Public universities obtained better results than private universities. The University of Valencia was ranked first, followed by the Complutense University of Madrid and the University of Granada. The most productive author was José Vicente Bagán, but the author with the highest h-index was Mariano Sanz and Manuel Toledado. The universities with the greatest output and highest citation rates had more international collaborations. The most developed fields in Spanish universities were Oral surgery, Oral medicine and Dental materials. The universities had different models of production. At universities such as Barcelona or Valencia, the production was focused on very few departments and authors. At the other extreme, the University of Granada had various sources of research and authors, which meant that its output and citation rate could increase more. University faculties must provide suitable academic and research training, and therefore must be assessed using objective criteria and bibliometric tools. Although the number of university schools and faculties that teach dentistry has increased, and particularly the number of private universities, there is no correlation between their quality and output and the number of places offered on their courses.

Health research is one mechanism to improve population-level health and should generally match the health needs of populations. However, there have been limited data to assess the trends in national-level cardiovascular research output, even as cardiovascular disease [CVD] has become the leading cause of morbidity and mortality worldwide. We performed a time trends analysis of cardiovascular research publications (1999-2008) downloaded from Web of Knowledge using a iteratively-tested cardiovascular bibliometric filter with >90% precision and recall. We evaluated cardiovascular research publications, five-year running actual citation indices [ACIs], and degree of international collaboration measured through the ratio of the fractional count of addresses from one country against all addresses for each publication. Global cardiovascular publication volume increased from 40 661 publications in 1999 to 55 284 publications in 2008, which represents a 36% increase. The proportion of cardiovascular publications from high-income, Organization for Economic Cooperation and Development [OECD] countries declined from 93% to 84% of the total share over the study period. High-income, OECD countries generally had higher fractional counts, which suggest less international collaboration, than lower income countries from 1999-2008. There was an inverse relationship between cardiovascular publications and age-standardized CVD morbidity and mortality rates, but a direct, curvilinear relationship between cardiovascular publications and Human Development Index from 1999-2008. Cardiovascular health research output has increased substantially in the past decade, with a greater share of citations being published from low- and middle-income countries. However, low- and middle-income countries with the higher burdens of cardiovascular disease continue to have lower research output than high-income countries, and thus require targeted research investments to improve cardiovascular health.

Abstract Objective: A comprehensive bibliometric analysis was conducted on publications for yoga therapy research in clinical populations. Methods: Major electronic databases were searched for articles in all languages published between 1967 and 2013. Databases included PubMed, PsychInfo, MEDLINE, IndMed, Indian Citation Index, Index Medicus for South-East Asia Region, Web of Knowledge, Embase, EBSCO, and Google Scholar. Nonindexed journals were searched manually. Key search words included yoga, yoga therapy, pranayama, asana. All studies met the definition of a clinical trial. All styles of yoga were included. The authors extracted the data. Results: A total of 486 articles met the inclusion criteria and were published in 217 different peer-reviewed journals from 29 different countries on 28,080 study participants. The primary result observed is the three-fold increase in number of publications seen in the last 10 years, inclusive of all study designs. Overall, 45% of the studies published were randomized controlled trials, 18% were controlled studies, and 37% were uncontrolled studies. Most publications originated from India (n=258), followed by the United States (n=122) and Canada (n=13). The top three disorders addressed by yoga interventions were mental health, cardiovascular disease, and respiratory disease. Conclusion: A surge in publications on yoga to mitigate disease-related symptoms in clinical populations has occurred despite challenges facing the field of yoga research, which include standardization and limitations in funding, time, and resources. The population at large has observed a parallel surge in the use of yoga outside of clinical practice. The use of yoga as a complementary therapy in clinical practice may lead to health benefits beyond traditional treatment alone; however, to effect changes in health care policy, more high-quality, evidence-based research is needed.

To study the temporal evolution of the bibliometric indices of internists with established research experience in order to predict the future behavior of researchers and to assess whether output focused on a specific area of internal medicine helps obtain greater visibility than in general internal medicine. We analyzed a representative group of members of the Spanish Society of Internal Medicine (SEMI) based on data obtained from the Web of Science. As an indicator of productivity, we analyzed the number of articles published. As impact indicators, we studied the impact factor (IF), the number of citations and the h-index. We analyzed 42 internists, with a mean experience of 30 years and a total of 6655 publications. The mean (SD) number of studies was 158 (96), the number of citations was 2,850 (2,865), the IF was 711 (549) and the h-index was 25 (11). These figures were higher for the specialist internists than for the general internists. There was a good relationship between the impact and productivity indicators (R(2)=.61-.89) and a poor relationship between these indicators and the years of experience (R(2)=.13-.19). The temporal evolution of these indicators for each individual researcher and for all researchers as a whole was adjusted to a second-degree polynomial model, with the h-index having the highest R(2) values. The h-index is the factor that had the best adjustment and least variability and could therefore help predict the future scientific output and impact of internists. The specialist researchers achieved greater visibility than the general internists. Copyright © 2015 Elsevier España, S.L.U. y Sociedad Española de Medicina Interna (SEMI). All rights reserved.

Spinal tuberculosis is the most common form of skeletal tuberculosis. However, there were limited data to evaluate the trend of spinal tuberculosis research. This study aims to investigate the trend of spinal tuberculosis research and compare the contribution of research from different countries and authors. Spinal tuberculosis-related publications from 1994 to 2015 were retrieved from the Web of Science database. Excel 2013, GraphPad Prism 5, and VOSviewer software were used to analyze the search results for number of publications, cited frequency, H-index, and country contributions. A total of 1558 papers were identified and were cited 16,152 times as of January 25, 2016. The United States accounted for 15.1% of the articles, 22.3% of the citations, and the highest H-index (33). China ranked third in total number of articles, fifth in citation frequency (815), and ranked seventh in H-index (13). The journal Spine (IF 2.297) had the highest number of publications. The author Jain A.K. has published the most papers in this field (20). The article titled "Tuberculosis of the spine: Controversies and a new challenge" was the most popular article and cited a total of 1138 times. The keyword "disease" was mentioned the most for 118 times and the word "bone fusion" was the latest hotspot by 2015. Literature growth in spinal tuberculosis is slowly expanding. Although publications from China are increasing, the quality of the articles still requires improvements. Meanwhile, the United States continues to be the largest contributor in the field of spinal tuberculosis. According to our bibliometric study, bone fusion may be an emerging topic within spinal tuberculosis research and is something that should be closely observed.

h-Index has been proposed as a useful bibliometric measure for quantifying research productivity. In this current study, we analyzed h-indices of editorial board members of Radiology journals and tested the hypothesis that editorial board members of Radiology journals with higher impact factors (IF) have higher h-indices. Sixty-two Radiology journals with IF >1 were included. Editorial board members were identified using the journals' websites. Editors' affiliations and research fields of interest were used to distinguish investigators with similar names. Bibliometric indices including number of publications, total citations, citations per publication, and h-index for each editorial board member were obtained using the Web of Science database. Chi-square or Wilcoxon rank-sum tests were used to test for differences in bibliographic measures or demographics between groups. Among the editorial boards of 62 journals, the median [interquartile range] board h-index was 26 [18, 31] and had 36 [17, 56] members. The median journal IF was 2.27 [1.74, 3.31]. We identified a total of 2204 distinct editors; they had a median [interquartile range] h-index of 23 [13, 35], 120 [58, 215] total publications, 1938 [682, 4634] total citations, and an average of 15.7 [9.96, 24.8] citations per publication. The boards of journals with IF above the median had significantly higher h-indices (P = .002), total publications (P = .01), and total and average citations (both any [P = .003, .009] and nonself-citations [P = .001, .002]) than journals below the median. Our data indicate that board members of Radiology journals with higher IF have greater h-indices compared to lower IF journals. Copyright © 2017 The Association of University Radiologists.

2011-11-10

While environmental research addresses scientific questions of possible societal relevance, it is unclear to what degree research focuses on environmental chemicals in need of documentation for risk assessment purposes. In a bibliometric analysis, we used SciFinder to extract Chemical Abstract Service (CAS) numbers for chemicals addressed by publications in the 78 major environmental science journals during 2000-2009. The Web of Science was used to conduct title searches to determine long-term trends for prominent substances and substances considered in need of research attention. The 119,636 journal articles found had 760,056 CAS number links during 2000-2009. The top-20 environmental chemicals consisted of metals, (chlorinated) biphenyls, polyaromatic hydrocarbons, benzene, and ethanol and contributed 12% toward the total number of links- Each of the top-20 substances was covered by 2,000-10,000 articles during the decade. The numbers for the 10-year period were similar to the total numbers of pre-2000 articles on the same chemicals. However, substances considered a high priority from a regulatory viewpoint, due to lack of documentation, showed very low publication rates. The persistence in the scientific literature of the top-20 chemicals was only weakly related to their publication in journals with a high impact factor, but some substances achieved high citation rates. The persistence of some environmental chemicals in the scientific literature may be due to a 'Matthew' principle of maintaining prominence for the very reason of having been well researched. Such bias detracts from the societal needs for documentation on less well known environmental hazards, and it may also impact negatively on the potentials for innovation and discovery in research.

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

Objectives A bibliometric analysis of the UK National Institute for Health Research (NIHR) Health Technology Assessment (HTA) monographs and their related journal articles by: (1) exploring the differences in citations to the HTA monographs in Google Scholar (GS), Scopus and Web of Science (WoS), and (2) comparing Scopus citations to the monographs with their related journal articles. Setting A study of 111 HTA monographs published in 2010 and 2011, and their external journal articles. Main outcome measures Citations to the monographs in GS, Scopus and WoS, and to their external journal articles in Scopus. Results The number of citations varied among the three databases, with GS having the highest and WoS the lowest; however, the citation-based rankings among the databases were highly correlated. Overall, 56% of monographs had a related publication, with the highest proportion for primary research (76%) and lowest for evidence syntheses (43%). There was a large variation in how the monographs were cited, compared to journal articles, resulting in more frequent problems, with unlinked citations in Scopus and WoS. When comparing differences in the number of citations between monograph publications with their related journal articles from the same project, we found that monographs received more citations than their journal articles for evidence syntheses and methodology projects; by contrast, journal articles related to primary research monographs were more highly cited than their monograph. Conclusions The numbers of citations to the HTA monographs differed considerably between the databases, but were highly correlated. When a HTA monograph had a journal article from the same study, there were more citations to the journal article for primary research, but more to the monographs for evidence syntheses. Citations to the related journal articles were more reliably recorded than citations to the HTA monographs. PMID:25694457

To identify the 100 most cited papers in cataract surgery, we performed a comprehensive bibliometric analysis basing on the literature search on the Thomson Reuters Web of Knowledge. The number of citations, including the total citations, latest 5y citations and average citation number per year (ACY), authorship, year of publication, major topics, journal of publication, country and institution of origin of each paper were recorded and then analyzed. Pearson's correlation analysis was conducted to evaluate the correlation between the published year and the number of citations. The correlation between journal's impact factor (IF) and number of citations was assessed as well. The most cited paper was the classic paper done by the European Society of Cataract & Refractive Surgeons (ESCRS) group. This paper focused on the topic of endophthalmitis. Not only the most cited papers originated from the USA, but also some American institutions like Johns Hopkins University, Harvard Medical School, etc. had the most citations. Pearson's correlation analysis indicated that the latest 5y citations and ACY were significantly related with the published year (5y citations: r =0.615, P <0.001; ACY: r =0.657, P <0.001), whereas no association between the total number of citations and published year was found ( r =0.045). Moreover, the IFs of journals were found to have no significant effect on the number of total citations. To our knowledge, this is the first study on the most influential papers in cataract surgery after a comprehensive research of relevant literatures. The present work may provide us concise information concerning the development history of cataract surgery over the past 66y.

A bibliometric analysis based on the Science Citation Index-Expanded (SCI-Expanded) database from the Web of Science was performed to review urban heat island (UHI) research from 1991 to 2015 and statistically assess its developments, trends, and directions. In total, 1822 papers published in 352 journals over the past 25 years were analyzed for scientific output; citations; subject categories; major journals; outstanding keywords; and leading countries, institutions, authors, and research collaborations. The number of UHI-related publications has continuously increased since 1991. Meteorology atmospheric sciences, environmental sciences, and construction building technology were the three most frequent subject categories. Building and Environment, International Journal of Climatology, and Theoretical and Applied Climatology were the three most popular publishing journals. The USA and China were the two leading countries in UHI research, contributing 49.56% of the total articles. Chinese Academy of Science, Arizona State University, and China Meteorological Administration published the most UHI articles. Weng QH and Santamouris M were the two most prolific authors. Author keywords were classified into four major groups: (1) research methods and indicators, e.g., remote sensing, field measurement, and models; (2) generation factors, e.g., impervious urban surfaces, urban geometry, waste heat, vegetation, and pollutants; (3) environmental effects, e.g., urban climate, heat wave, ecology, and pollution; and (4) mitigation and adaption strategies, e.g., roof technology cooling, reflective cooling, vegetation cooling, and urban geometry cooling. A comparative analysis of popular issues revealed that UHI determination (intensity, heat source, supporting techniques) remains the central topic, whereas UHI impacts and mitigation strategies are becoming the popular issues that will receive increasing scientific attention in the future. Modeling will continue to be the leading research method, and remote sensing will be used more widely. Additionally, a combination of remote sensing and field measurements with models is expected.

The Matthew effect in environmental science publication: A bibliometric analysis of chemical substances in journal articles

PubMed Central

2011-01-01

Background While environmental research addresses scientific questions of possible societal relevance, it is unclear to what degree research focuses on environmental chemicals in need of documentation for risk assessment purposes. Methods In a bibliometric analysis, we used SciFinder to extract Chemical Abstract Service (CAS) numbers for chemicals addressed by publications in the 78 major environmental science journals during 2000-2009. The Web of Science was used to conduct title searches to determine long-term trends for prominent substances and substances considered in need of research attention. Results The 119,636 journal articles found had 760,056 CAS number links during 2000-2009. The top-20 environmental chemicals consisted of metals, (chlorinated) biphenyls, polyaromatic hydrocarbons, benzene, and ethanol and contributed 12% toward the total number of links- Each of the top-20 substances was covered by 2,000-10,000 articles during the decade. The numbers for the 10-year period were similar to the total numbers of pre-2000 articles on the same chemicals. However, substances considered a high priority from a regulatory viewpoint, due to lack of documentation, showed very low publication rates. The persistence in the scientific literature of the top-20 chemicals was only weakly related to their publication in journals with a high impact factor, but some substances achieved high citation rates. Conclusions The persistence of some environmental chemicals in the scientific literature may be due to a 'Matthew' principle of maintaining prominence for the very reason of having been well researched. Such bias detracts from the societal needs for documentation on less well known environmental hazards, and it may also impact negatively on the potentials for innovation and discovery in research.

To assess HIV/AIDS research productivity in the 27 countries of the European Union (EU), and the structural level factors associated with levels of HIV/AIDS research productivity. A bibliometric analysis was conducted with systematic search methods used to locate HIV/AIDS research publications (period of 1 January 2002 to 31 December 2011; search databases: MEDLINE (Ovid, PubMed), EMBASE, ISI-Thomson Web of Science; no language restrictions). The publication rate (number of HIV/AIDS research publications per million population in 10 years) and the rate of articles published in HIV/AIDS journals and selected journals with moderate to very high (IF ≥3) 5-year impact factors were used as markers for HIV research productivity. A negative binomial regression model was fitted to assess the impact of structural level factors (sociodemographic, health, HIV prevalence and research/development indicators) associated with the variation in HIV research productivity. The total numbers of HIV/AIDS research publications in 2002-2011 by country ranged from 7 to 9128 (median 319). The median publication rate (per million population in 10 years) was 45 (range 5-150) for all publications. Across all countries, 16% of the HIV/AIDS research was published in HIV/AIDS journals and 7% in selected journals with IF ≥3. Indicators describing economic (gross domestic product), demographic (size of the population) and epidemiological (HIV prevalence) conditions as well as overall scientific activity (total research output) in a country were positively associated with HIV research productivity. HIV research productivity varies noticeably across EU countries, and this variation is associated with recognisable structural factors. Published by the BMJ Publishing Group Limited.

2017-12-01

The objective of our study was to investigate radiology manuscript characteristics that influence citation rate, capturing features of manuscript construction that are discrete from study design. Consecutive articles published from January 2004 to June 2004 were collected from the six major radiology journals with the highest impact factors: Radiology (impact factor, 5.076), Investigative Radiology (2.320), American Journal of Neuroradiology (AJNR) (2.384), RadioGraphics (2.494), European Radiology (2.364), and American Journal of Roentgenology (2.406). The citation count for these articles was retrieved from the Web of Science, and 29 article characteristics were tabulated manually. A point-biserial correlation, Spearman rank-order correlation, and multiple regression model were performed to predict citation number from the collected variables. A total of 703 articles-211 published in Radiology, 48 in Investigative Radiology, 106 in AJNR, 52 in RadioGraphics, 129 in European Radiology, and 157 in AJR-were evaluated. Punctuation was included in the title in 55% of the articles and had the highest statistically significant positive correlation to citation rate (point-biserial correlation coefficient [r pb ] = 0.85, p < 0.05). Open access status provided a low-magnitude, but significant, correlation to citation rate (r pb = 0.140, p < 0.001). The following variables created a significant multiple regression model to predict citation count (p < 0.005, R 2 = 0.186): study findings in the title, abstract word count, abstract character count, total number of words, country of origin, and all authors in the field of radiology. Using bibliometric knowledge, authors can craft a title, abstract, and text that may enhance visibility and citation count over what they would otherwise experience.

A scholar's h-index is defined as the number of h papers published, each of which has been cited at least h times. We hypothesized that the h-index strongly correlates with the academic rank of surgical oncologists. We utilized the National Cancer Institute (NCI) website to identify NCI-designated Comprehensive Cancer Centers (CCC) and Doximity to identify the 50 highest-ranked general surgery residency programs with surgical oncology divisions. Demographic data of respective academic surgical oncologists were collected from departmental websites and Grantome. Bibliometric data were obtained from Web of Science. We identified 544 surgical oncologists from 64 programs. Increased h-index was associated with academic rank (p < 0.001), male gender (p < 0.001), number of National Institutes of Health (NIH) grants (p < 0.001), and affiliation with an NCI CCC (p = 0.018) but not number of additional degrees (p = 0.661) or Doximity ranking (p = 0.102). H-index was a stronger predictor of academic rank (r = 0.648) than total publications (r = 0.585) or citations (r = 0.450). This is the first report to assess the h-index within academic surgical oncology. H-index is a bibliometric predictor of academic rank that correlates with NIH grant funding and NCI CCC affiliation. We also highlight a previously unexpected and unappreciated gender disparity in the academic productivity of US surgical oncologists. When academic rank was accounted for, female surgical oncologists had lower h-indices compared with their male colleagues. Evaluation of the etiologies of this gender disparity is needed to address barriers to academic productivity faced by female surgical oncologists as they progress through their careers.

We analyzed the scientific production of members of the Spanish Society of Vascular and Interventional Radiology (SERVEI) from 2010 to 2015. We retrospectively analyzed the indexed scientific productivity of all SERVEI members for the last 6 years as measured by bibliometric indexes. Different databases were used (e.g., PubMed, Scopus, Web of Knowledge) to retrieve the total number of publications, number of citations, and h-index. Every article was assigned the impact factor of its publication year and its corresponding quartile according to Journal Citation Reports. The relationships between all of these parameters and the Spanish region, the gender and age of the interventional radiologists (IRs), and their connection to the university environment were also studied. A total of 519 scientific articles from 247 SERVEI members working in 118 Spanish hospitals were included, an average of 0.3 articles per interventionist/year. Most of the manuscripts were published in impact journals (52.2%) and placed in the lowest quartile (Q4). Navarre, Aragon, and Catalonia were the regions with the highest publication rate during the period studied (1.7, 0.92, and 0.6 publications per interventionist/year, respectively). Only 57 articles (12.6%) were published in 11 of the 125 journals under the category of Radiology, Nuclear Medicine, and Medical Imaging according to JCR. The scientific production of the Spanish IRs in the last 6 years is difficult to interpret. However, more than 50% of IRs published one article in the last 6 years. Finally, it would be advisable to repeat this study over a period of time in order to compare.

AIM To identify the 100 most cited papers in cataract surgery, we performed a comprehensive bibliometric analysis basing on the literature search on the Thomson Reuters Web of Knowledge. METHODS The number of citations, including the total citations, latest 5y citations and average citation number per year (ACY), authorship, year of publication, major topics, journal of publication, country and institution of origin of each paper were recorded and then analyzed. Pearson's correlation analysis was conducted to evaluate the correlation between the published year and the number of citations. The correlation between journal's impact factor (IF) and number of citations was assessed as well. RESULTS The most cited paper was the classic paper done by the European Society of Cataract & Refractive Surgeons (ESCRS) group. This paper focused on the topic of endophthalmitis. Not only the most cited papers originated from the USA, but also some American institutions like Johns Hopkins University, Harvard Medical School, etc. had the most citations. Pearson's correlation analysis indicated that the latest 5y citations and ACY were significantly related with the published year (5y citations: r=0.615, P<0.001; ACY: r=0.657, P<0.001), whereas no association between the total number of citations and published year was found (r=0.045). Moreover, the IFs of journals were found to have no significant effect on the number of total citations. CONCLUSION To our knowledge, this is the first study on the most influential papers in cataract surgery after a comprehensive research of relevant literatures. The present work may provide us concise information concerning the development history of cataract surgery over the past 66y. PMID:29062780

The information value of early career productivity in mathematics: a ROC analysis of prediction errors in bibliometricly informed decision making.

PubMed

Lindahl, Jonas; Danell, Rickard

The aim of this study was to provide a framework to evaluate bibliometric indicators as decision support tools from a decision making perspective and to examine the information value of early career publication rate as a predictor of future productivity. We used ROC analysis to evaluate a bibliometric indicator as a tool for binary decision making. The dataset consisted of 451 early career researchers in the mathematical sub-field of number theory. We investigated the effect of three different definitions of top performance groups-top 10, top 25, and top 50 %; the consequences of using different thresholds in the prediction models; and the added prediction value of information on early career research collaboration and publications in prestige journals. We conclude that early career performance productivity has an information value in all tested decision scenarios, but future performance is more predictable if the definition of a high performance group is more exclusive. Estimated optimal decision thresholds using the Youden index indicated that the top 10 % decision scenario should use 7 articles, the top 25 % scenario should use 7 articles, and the top 50 % should use 5 articles to minimize prediction errors. A comparative analysis between the decision thresholds provided by the Youden index which take consequences into consideration and a method commonly used in evaluative bibliometrics which do not take consequences into consideration when determining decision thresholds, indicated that differences are trivial for the top 25 and the 50 % groups. However, a statistically significant difference between the methods was found for the top 10 % group. Information on early career collaboration and publication strategies did not add any prediction value to the bibliometric indicator publication rate in any of the models. The key contributions of this research is the focus on consequences in terms of prediction errors and the notion of transforming uncertainty into risk when we are choosing decision thresholds in bibliometricly informed decision making. The significance of our results are discussed from the point of view of a science policy and management.

We investigated the inter-rater reliability of Web of Science (WoS) and Scopus when calculating the h-index of 25 senior scientists in the Clinical Epidemiology Program of the Ottawa Hospital Research Institute. Bibliometric information and the h-indices for the subjects were computed by four raters using the automatic calculators in WoS and Scopus. Correlation and agreement between ratings was assessed using Spearman's correlation coefficient and a Bland-Altman plot, respectively. Data could not be gathered from Google Scholar due to feasibility constraints. The Spearman's rank correlation between the h-index of scientists calculated with WoS was 0.81 (95% CI 0.72-0.92) and with Scopus was 0.95 (95% CI 0.92-0.99). The Bland-Altman plot showed no significant rater bias in WoS and Scopus; however, the agreement between ratings is higher in Scopus compared to WoS. Our results showed a stronger relationship and increased agreement between raters when calculating the h-index of a scientist using Scopus compared to WoS. The higher inter-rater reliability and simple user interface used in Scopus may render it the more effective database when calculating the h-index of senior scientists in epidemiology. © 2016 Health Libraries Group.

Trends in nursing ethics research: Mapping the literature production.

Blažun Vošner, Helena; Železnik, Danica; Kokol, Peter; Vošner, Janez; Završnik, Jernej

2017-12-01

There have been a number of debates in the field of nursing ethics. Researchers have focused on various aspects of nursing ethics, such as professional ethics, professional, nursing and ethical values. Within this research, a variety of literature reviews have been conducted, but to the best of our knowledge, bibliometric mapping has not yet been used. This article aims to analyse the production of literature within nursing ethics research. In order to examine publishing patterns, we focused on publishing dynamics, prolific research entities and the most-cited articles. We additionally visualised the content of the literature using a novel mixed-method approach, combining bibliometric analysis and mapping with thematic analysis. Ethical considerations: In our study, ethical review was not required. A total of 1416 information sources were found in the Scopus database. Overall, literature production has increased; however, in recent years, the quantity of published material has begun to decrease. The most prolific countries are the United States, the United Kingdom and Canada, and the most prolific source titles are Nursing Ethics, Journal of Advanced Nursing and Nursing Times. Lately, research in the field of nursing ethics has been focused more on life care (providing for the basic needs of older residents), moral distress and community nursing. The dynamics of research literature production showed an exponential rise in the number of published information sources - a rise which started in the period between 1974 and 1998. Since that period, the trend has stabilised, which might indicate that nursing ethics research is starting a transition to a mature phase. The innovative use of bibliometric analysis and mapping, together with thematic analysis, is a useful tool for analysis of research production in the field of nursing ethics. The results presented can be an excellent starting point for literature reviews and more exhaustive data, information and knowledge seeking.

Bibliometric studies are increasingly being used for research assessment by involving the application of statistical methods to scientific publications to obtain the bibliographics for each country. The main objective of this study was to analyse the research productivity originating from 13 Middle Eastern Arab (MEA) countries with articles published in toxicology journals. Data from January 1, 2003 till December 31, 2012 were searched for documents with specific words in the toxicology field as a "source title" in any one of the 13 MEA countries. Research productivity was evaluated based on a methodology developed and used in other bibliometric studies. Research productivity was adjusted to the national population and nominal gross domestic product (GDP) per capita. Documents (n = 1,240) were retrieved from 73 international peer-reviewed toxicology journals. The h-index of the retrieved documents was 39. Of the 73 journal titles, 52 (69.9%) have their IF listed in the ISI Journal Citation Reports 2012; 198 documents (16.0%) were published in journals that had no official IF. After adjusting for economy and population power, Egypt (193.6), Palestine (18.1), Kingdom of Saudi Arabia (KSA) (13.0), and Jordan (11.5) had the highest research productivity. Countries with large economies, such as the Kuwait, United Arab Emirates (UAE), and Oman, tended to rank relatively low after adjustment of GDP. The total number of citations at the time of data analysis (August 4, 2013) was 10,991, with a median (interquartile range) of 4 (1-11). MEA collaborated more with countries in the MEA regions (16.7%), especially KSA, Egypt, and UAE, followed by Europe (14.4%), especially with the United Kingdom and Germany. The present data show a promising rise and a good start for toxicology research activity in toxicology journals in the Arab world. Research output is low in some countries, which can be improved by investing in more international and national collaborative research projects in the field of toxicology.

Mapping patient safety: a large-scale literature review using bibliometric visualisation techniques

2014-01-01

Background The amount of scientific literature available is often overwhelming, making it difficult for researchers to have a good overview of the literature and to see relations between different developments. Visualisation techniques based on bibliometric data are helpful in obtaining an overview of the literature on complex research topics, and have been applied here to the topic of patient safety (PS). Methods On the basis of title words and citation relations, publications in the period 2000–2010 related to PS were identified in the Scopus bibliographic database. A visualisation of the most frequently cited PS publications was produced based on direct and indirect citation relations between publications. Terms were extracted from titles and abstracts of the publications, and a visualisation of the most important terms was created. The main PS-related topics studied in the literature were identified using a technique for clustering publications and terms. Results A total of 8480 publications were identified, of which the 1462 most frequently cited ones were included in the visualisation. The publications were clustered into 19 clusters, which were grouped into three categories: (1) magnitude of PS problems (42% of all included publications); (2) PS risk factors (31%) and (3) implementation of solutions (19%). In the visualisation of PS-related terms, five clusters were identified: (1) medication; (2) measuring harm; (3) PS culture; (4) physician; (5) training, education and communication. Both analysis at publication and term level indicate an increasing focus on risk factors. Conclusions A bibliometric visualisation approach makes it possible to analyse large amounts of literature. This approach is very useful for improving one's understanding of a complex research topic such as PS and for suggesting new research directions or alternative research priorities. For PS research, the approach suggests that more research on implementing PS improvement initiatives might be needed. PMID:24625640

DNA Damage Repair System in Plants: A Worldwide Research Update.

PubMed

Gimenez, Estela; Manzano-Agugliaro, Francisco

2017-10-30

Living organisms are usually exposed to various DNA damaging agents so the mechanisms to detect and repair diverse DNA lesions have developed in all organisms with the result of maintaining genome integrity. Defects in DNA repair machinery contribute to cancer, certain diseases, and aging. Therefore, conserving the genomic sequence in organisms is key for the perpetuation of life. The machinery of DNA damage repair (DDR) in prokaryotes and eukaryotes is similar. Plants also share mechanisms for DNA repair with animals, although they differ in other important details. Plants have, surprisingly, been less investigated than other living organisms in this context, despite the fact that numerous lethal mutations in animals are viable in plants. In this manuscript, a worldwide bibliometric analysis of DDR systems and DDR research in plants was made. A comparison between both subjects was accomplished. The bibliometric analyses prove that the first study about DDR systems in plants (1987) was published thirteen years later than that for other living organisms (1975). Despite the increase in the number of papers about DDR mechanisms in plants in recent decades, nowadays the number of articles published each year about DDR systems in plants only represents 10% of the total number of articles about DDR. The DDR research field was done by 74 countries while the number of countries involved in the DDR & Plant field is 44. This indicates the great influence that DDR research in the plant field currently has, worldwide. As expected, the percentage of studies published about DDR systems in plants has increased in the subject area of agricultural and biological sciences and has diminished in medicine with respect to DDR studies in other living organisms. In short, bibliometric results highlight the current interest in DDR research in plants among DDR studies and can open new perspectives in the research field of DNA damage repair.

Bibliometrics refers to the collection and measurement of publishing and citation data configurations with the goal of quantifying the influence of scholarly activities. Advantages of bibliometrics include the generation of quantitative indicators of impact, productivity, quality and collaboration. Those parties who benefit from the results of bibliometric analysis include researchers, educators, journal publishers, employers and research funding bodies. A bibliometric analysis was completed of peer-reviewed literature from 1991 to 2015, written by Australian occupational therapists (who were able to be identified as such), and indexed in the Science Citation Index-Expanded (SCI-Expanded) or the Social Sciences Citation Index (SSCI) databases. "Occupational therapy" and "occupational therapist(s)" were used as keywords to search journal articles' publication title, abstract, author details, keywords and KeyWord Plus. Between 1991 and 2015, 752 peer-reviewed journal articles were published by Australian occupational therapy authors. On average, those articles had 3.7 authors, 35 references, and were nine pages in length. The top four journals in which Australian occupational therapists published were Australian Occupational Therapy Journal, British Journal of Occupational Therapy, American Journal of Occupational Therapy, and Physical and Occupational Therapy in Paediatrics. The four Australian institutions that generated the largest number of occupational therapy articles were the University of Queensland, University of Sydney, La Trobe University, and Monash University. The top four countries with whom Australian authors collaborated in manuscript writing were the United Kingdom, United States, Canada and Sweden. The volume of occupational therapy peer-reviewed literature has grown over the last two decades. Australian authors have and continue to make significant contributions to the occupational therapy body of knowledge nationally and internationally. © 2018 Occupational Therapy Australia.

Information and communication technology is developing rapidly and it is incorporated in many health care processes, but in spite of that fact we can still notice that nursing informatics competencies had received limited attention in basic nursing education curricula in Europe and especially in Eastern European countries. The purpose of the present paper is to present the results of a bibliometric analysis of the nursing informatics competencies scientific literature production. We applied the bibliometrics analysis to the corpus of 332 papers found in SCOPUS, related to nursing informatics competencies. The results showed that there is a positive trend in the number of published papers per year, indicating the increased research interest in nursing informatics competencies. Despite the fact that the first paper was published in Denmark, the most prolific country regarding the research in nursing informatics competencies is United States as are their institutions and authors.

Novel bibliometric indexes (commonly known as altmetrics) are gaining interest within the scientific community and might represent an important alternative measure of research quality and output. We evaluate how these new metrics correlate with established bibliometric indexes such as the impact factor (IF), currently used as a measure of scientific production as well as a criterion for scientific research funding, and how they might be helpful in assessing the impact of research. We calculated altmetrics scores for all the articles published at our institution during a single year and examined the correlation between altmetrics scores and IFs as a measure of research quality and impact in all departments. For all articles from the various departments published in a single year, the altmetrics score and the sum of all IFs showed a strong and significant correlation (Spearman's rho 0.88). The correlation was significant also when the major components of altmetrics, including Facebook, Twitter and Mendeley, were analyzed. The implementation of altmetrics has been found to be easy and effective at both the researcher and librarian levels. The novel bibliographic index altmetrics is consistent and reliable and can complement or be considered a valid alternative to standard bibliometric indexes to benchmark output and quality of research for academic and funding purposes.

It has been argued that science and society are in the midst of a far-reaching renegotiation of the social contract between science and society, with society becoming a far more active partner in the creation of knowledge. On the one hand, new forms of knowledge production are emerging, and on the other, both science and society are experiencing a rapid acceleration in new forms of knowledge utilization. Concomitantly since the Second World War, the science underpinning the knowledge utilization field has had exponential growth. Few in-depth examinations of this field exist, and no comprehensive analyses have used bibliometric methods. Using bibliometric analysis, specifically first author co-citation analysis, our group undertook a domain analysis of the knowledge utilization field, tracing its historical development between 1945 and 2004. Our purposes were to map the historical development of knowledge utilization as a field, and to identify the changing intellectual structure of its scientific domains. We analyzed more than 5,000 articles using citation data drawn from the Web of Science. Search terms were combinations of knowledge, research, evidence, guidelines, ideas, science, innovation, technology, information theory and use, utilization, and uptake. We provide an overview of the intellectual structure and how it changed over six decades. The field does not become large enough to represent with a co-citation map until the mid-1960s. Our findings demonstrate vigorous growth from the mid-1960s through 2004, as well as the emergence of specialized domains reflecting distinct collectives of intellectual activity and thought. Until the mid-1980s, the major domains were focused on innovation diffusion, technology transfer, and knowledge utilization. Beginning slowly in the mid-1980s and then growing rapidly, a fourth scientific domain, evidence-based medicine, emerged. The field is dominated in all decades by one individual, Everett Rogers, and by one paradigm, innovation diffusion. We conclude that the received view that social science disciplines are in a state where no accepted set of principles or theories guide research (i.e., that they are pre-paradigmatic) could not be supported for this field. Second, we document the emergence of a new domain within the knowledge utilization field, evidence-based medicine. Third, we conclude that Everett Rogers was the dominant figure in the field and, until the emergence of evidence-based medicine, his representation of the general diffusion model was the dominant paradigm in the field.

Evidence-based practice is a foundation to clinical excellence. However there remains little evidence on the characteristics of authors who contribute to the evidence-base and whether these have changed over time. The purpose of this study was to explore these characteristics by undertaking a bibliometric analysis to explore publication and authorship characteristics in a leading sub-speciality orthopaedic journal (The Knee) over a 20-year period. All articles published in The Knee in 1996, 2006 and 2016 were identified. For each article, data collected included: highest academic award; profession; gender; continent of first and last author; total number of authors; the level of evidence; and funding source. We analysed temporal changes in these variables using appropriate statistical models. A total of 413 papers were analysed. Between 1996 to 2016 there has been a significant increase in the overall number of authors, the number of paper submitted from Asia, the proportion of Level 1 or 2 tiered evidence, the proportion of people with Bachelor or Master-level degrees as their highest level of educational award and the proportion of non-medically qualified authors (P<0.001). From 2006 to 2016 there was a significant increase in the proportion of articles whose first author was female (P=0.03), but no significant change in the number of females as last author (P=0.43). The findings indicate that there have been changes in publication and authorship characteristics in this sub-speciality orthopaedic journal during the past 20years. This provides encouraging indication of greater diversification and internationalisation of orthopaedic research. Copyright © 2018 Elsevier B.V. All rights reserved.

Packer, Abel Laerte

2015-07-01

This report presents a set of bibliometric indicators and statistics which explain the high level of production of articles on research in public and collective health in Brazil which are published in the main nationally edited journals in the field. The predominance of publications in the Portuguese language by Brazilian authors results in a lower impact in terms of citations received as measured by the bibliometric indexes Scimago/Scopus and JCR/WoS. These bibliometric indexes are used to measure the production and performance of research and journals. Nevertheless, the performance of these same journals stands out in SciELO, and is competitive internationally in the broader context of Google Scholar Metrics. The challenge faced by journals in Brazil is developing and applying editorial policies for the valuation of research with a national focus, and its internationalization.

This study uses several bibliometric indices to explore the temporal course of publication trends regarding the bilingual advantage in executive control over a ten-year window. These indices include the number of published papers, numbers of citations, and the journal impact factor. According to the information available in their abstracts, studies were classified into one of four categories: supporting, ambiguous towards, not mentioning, or challenging the bilingual advantage. Results show that the number of papers challenging the bilingual advantage increased notably in 2014 and 2015. Both the average impact factor and the accumulated citations as of June 2016 were equivalent between categories. However, of the studies published in 2014, those that challenge the bilingual advantage accumulated more citations in June 2016 than those supporting it. Our findings offer evidence-based bibliometric information about the current state of the literature and suggest a change in publication trends regarding the literature on the bilingual advantage.

The Journal of Psychology: Interdisciplinary and Applied is a leading international journal in psychology dating back to 1935. This study examines its publications since its creation utilizing a bibliometric analysis. The primary objective is to provide a complete overview of the key factors affecting the journal. This analysis includes such key issues as the publication and citation structure of the journal, its most cited articles, and the leading authors, institutions, and countries referenced in the journal. The work uses the Scopus database to classify the bibliographic material. Additionally, the analysis provides a graphical mapping of the bibliographic data by using visualization of similarities viewer software. This software uses several bibliometric techniques including co-citation, bibliographic coupling and co-occurrence of keywords. The Journal of Psychology is strongly connected to most of the current leading journals in psychology, and currently has a 5-year impact factor of 1.77 (Thomson Reuters, 2015 Journal Citation Reports).

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.

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

PubMed

Jones, Teresa H; Hanney, Steve

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

Recently, significant contributions to the study of endocrinology and metabolism have been made. The national contribution, however, has not been reported. The aim of this study was to assess national efforts in the field of endocrinology and metabolism. A Web of Science search was performed using subject categories "endocrinology & metabolism" to identify articles published from 2010 to 2014. The total and per capita numbers of articles and citations were analysed for different countries. A total of 79,394 articles were published on endocrinology and metabolism from 2010 to 2014. Most were published in North America, East Asia, and Europe. The majority (82.28%) were reported by authors in high-income countries, 17.64% were published in middle-income countries, and only 0.08% were published in low-income countries. Authors in the United States published the most articles (27.38%), followed by China (7.22%), Italy (5.70%), the United Kingdom (5.6%), and Japan (5.54%). Articles published by authors in the United States had the most citations (260,934). A positive correlation was found between the number of publications and population/gross domestic product (GDP; p < 0.01). When normalised to population size, the ranking for the most publications was Denmark, Sweden, and the Netherlands; when normalised to GDP, the ranking was Denmark, Greece, and the Netherlands. The majority of endocrinology and metabolism articles were published by authors from high-income countries with few from low-income countries. The United States was the most productive country. However, when population size and GDP were considered, some European countries were ranked higher.

Spectrophotometric Analysis of Phenolic Compounds in Grapes and Wines.

2017-05-24

Phenolic compounds are of crucial importance for red wine color and mouthfeel attributes. A large number of enzymatic and chemical reactions involving phenolic compounds take place during winemaking and aging. Despite the large number of published analytical methods for phenolic analyses, the values obtained may vary considerably. In addition, the existing scientific knowledge needs to be updated, but also critically evaluated and simplified for newcomers and wine industry partners. The most used and widely cited spectrophotometric methods for grape and wine phenolic analysis were identified through a bibliometric search using the Science Citation Index-Expanded (SCIE) database accessed through the Web of Science (WOS) platform from Thompson Reuters. The selection of spectrophotometry was based on its ease of use as a routine analytical technique. On the basis of the number of citations, as well as the advantages and disadvantages reported, the modified Somers assay appears as a multistep, simple, and robust procedure that provides a good estimation of the state of the anthocyanins equilibria. Precipitation methods for total tannin levels have also been identified as preferred protocols for these types of compounds. Good reported correlations between methods (methylcellulose precipitable vs bovine serum albumin) and between these and perceived red wine astringency, in combination with the adaptation to high-throughput format, make them suitable for routine analysis. The bovine serum albumin tannin assay also allows for the estimation of the anthocyanins content with the measurement of small and large polymeric pigments. Finally, the measurement of wine color using the CIELab space approach is also suggested as the protocol of choice as it provides good insight into the wine's color properties.

Systems thinking in public health: a bibliographic contribution to a meta-narrative review.

PubMed

Chughtai, Saad; Blanchet, Karl

2017-05-01

Research across the formal, natural and social sciences has greatly expanded our knowledge about complex systems in recent decades, informing a broadly inclusive, cross-disciplinary conceptual framework referred to as Systems Thinking (ST). Its use in public health is rapidly increasing, although there remains a poor understanding of how these ideas have been imported, adapted and elaborated by public health research networks worldwide. This review employed a mixed methods approach to narrate the development of ST in public health. Tabulated results from a literature search of the Web of Science Core Collection database were used to perform a bibliometric analysis and literature review. Annual publication counts and citation scores were used to analyse trends and identify popular and potential 'landmark' publications. Citation network and co-authorship network diagrams were analysed to identify groups of articles and researchers in various network roles. Our search string related to 763 publications. Filtering excluded 208 publications while citation tracing identified 2 texts. The final 557 publications were analysed, revealing a near-exponential growth in literature over recent years. Half of all articles were published after 2010 with almost a fifth (17.8%) published in 2014. Bibliographic analysis identified five distinct citation and co-authorship groups homophilous by common geography, research focus, inspiration or institutional affiliation. As a loosely related set of sciences, many public health researchers have developed different aspects of ST based on their underlying perspective. Early studies were inspired by Management-related literature, while later groups adopted a broadly inclusive understanding which incorporated related Systems sciences and approaches. ST is an increasingly popular subject of discussion within public health although its understanding and approaches remain unclear. Briefly tracing the introduction and development of these ideas and author groups in public health literature may provide clarity and opportunities for further learning, research and development. © The Author 2017.

Objective Acupuncture has become popular and widely practiced in many countries around the world. Despite the large amount of acupuncture-related literature that has been published, broader trends in the prevalence and scope of acupuncture research remain underexplored. The current study quantitatively analyzes trends in acupuncture research publications in the past 20 years. Methods A bibliometric approach was used to search PubMed for all acupuncture-related research articles including clinical and animal studies. Inclusion criteria were articles published between 1995 and 2014 with sufficient information for bibliometric analyses. Rates and patterns of acupuncture publication within the 20 year observational period were estimated, and compared with broader publication rates in biomedicine. Identified eligible publications were further analyzed with respect to study type/design, clinical condition addressed, country of origin, and journal impact factor. Results A total of 13,320 acupuncture-related publications were identified using our search strategy and eligibility criteria. Regression analyses indicated an exponential growth in publications over the past two decades, with a mean annual growth rate of 10.7%. This compares to a mean annual growth rate of 4.5% in biomedicine. A striking trend was an observed increase in the proportion of randomized clinical trials (RCTs), from 7.4% in 1995 to 20.3% in 2014, exceeding the 4.5% proportional growth of RCTs in biomedicine. Over the 20 year period, pain was consistently the most common focus of acupuncture research (37.9% of publications). Other top rankings with respect to medical focus were arthritis, neoplasms/cancer, pregnancy or labor, mood disorders, stroke, nausea/vomiting, sleep, and paralysis/palsy. Acupuncture research was conducted in 60 countries, with the top 3 contributors being China (47.4%), United States (17.5%), and United Kingdom (8.2%). Retrieved articles were published mostly in complementary and alternative medicine (CAM) journals with impact factors ranging between 0.7 and 2.8 in the top 20 journals, followed by journals specializing in neuroscience, pain, anesthesia/analgesia, internal medicine and comprehensive fields. Conclusion Acupuncture research has grown markedly in the past two decades, with a 2-fold higher growth rate than for biomedical research overall. Both the increases in the proportion of RCTs and the impact factor of journals support that the quality of published research has improved. While pain was a consistently dominant research focus, other topics gained more attention during this time period. These findings provide a context for analyzing strengths and gaps in the current state of acupuncture research, and for informing a comprehensive strategy for further advancing the field.

Acceptance and Commitment Therapy (ACT) has been demonstrated to be effective in reducing depressive symptoms. However, little is known how and for whom therapeutic change occurs, specifically in web-based interventions. This study focuses on the mediators, moderators and predictors of change during a web-based ACT intervention. Data from 236 adults from the general population with mild to moderate depressive symptoms, randomized to either web-based ACT (n = 82) or one of two control conditions (web-based Expressive Writing (EW; n = 67) and a waiting list (n = 87)), were analysed. Single and multiple mediation analyses, and exploratory linear regression analyses were performed using PROCESS and linear regression analyses, to examine mediators, moderators and predictors on pre- to post- and follow-up treatment change of depressive symptoms. The treatment effect of ACT versus the waiting list was mediated by psychological flexibility and two mindfulness facets. The treatment effect of ACT versus EW was not significantly mediated. The moderator analyses demonstrated that the effects of web-based ACT did not vary according to baseline patient characteristics when compared to both control groups. However, higher baseline depressive symptoms and positive mental health and lower baseline anxiety were identified as predictors of outcome across all conditions. Similar results are found for follow-up. The findings of this study corroborate the evidence that psychological flexibility and mindfulness are distinct process mechanisms that mediate the effects of web-based ACT intervention. The results indicate that there are no restrictions to the allocation of web-based ACT intervention and that web-based ACT can work for different subpopulations. Netherlands Trial Register NTR2736 .

[Congresses of the Spanish Association of Pediatrics: bibliometric analysis as a springboard for debate].

González de Dios, J; Paredes Cencillo, C

Congresses are periodic meetings that are required to make known and discuss advances in the various fields of medicine. Bibliometric indicators are important tools used to determine the quality of scientific publications. However, this type of study is infrequently performed in free communications of congresses. A bibliometric study of all the free communications published in the congresses of the Spanish Association of Pediatrics over 4 years, divided in two periods (1996-1997 and 2000-2001) (n = 2677) was performed. Bibliometric indicators were classified into quantitative (productivity), qualitative (statistical accessibility) and scientific evidence. Quantitative indicators: There were 928 free communications in 1996, 681 in 1997, 560 in 2000, and 508 in 2001. Eighty-eight percent were in poster format and 87 % were in structured format. There was a median of six authors per communication. The main subject areas were infectology, neonatology, hemato-oncology, neurology and endocrinology. Ninety-five per cent of communications were signed by hospitals with a marked contribution by hospitals in Andalusia and Madrid. Qualitative indicators: Statistical accessibility < 2 in 86 % and > 7 in 2.9 %. Scientific evidence indicators: The quality of scientific evidence was good in only 1 % and was average in 9 %, since 90 % of all the studies were descriptive (mainly clinical cases). Evidence-based methodological concepts were used in only 1.9 %. Compared with 1996-1997, in 2000-2001 there were fewer communications, more posters, and more structured communications, as well as greater statistical accessibility and better scientific evidence indicators, but these differences were not statistically significant. Bibliometric study of the congresses of the Spanish Association of Pediatrics is a good starting point to analyze the quality of pediatric meetings and discuss possible solutions: a rigorous scientific committee with quality criteria, more analytical and/or experimental studies and fewer descriptive studies (especially clinical cases); restricting the number of authors per communication, greater collaboration with epidemiologists and/or biostatisticians, and favoring structured communications would also improve quality.

Associations Between NIH Funding and Advanced Bibliometric Indices Among Radiological Investigators.

Rosenkrantz, Andrew B; Jiang, Anthony

2016-06-01

Whereas data support the h index (reflecting both publications and citations) as an indicator of academic productivity, other advanced bibliometric indices aiming to address shortcomings of the h index remain poorly studied. Our objective was to compare the associations between bibliometric indices and total National Institutes of Health (NIH) grant funding among investigators within U.S. academic radiology departments. NIH grant funding amounts for 400 NIH-funded investigators within radiology departments were obtained from Blue Ridge Institute for Medical Research. Investigators' publications and associated citations were identified using Scopus. Indices computed for each investigator included: publication count, citation count, h index, i-10 index, hc index (h index adjusted for recency of publications), m quotient (h index adjusted for career duration), and e index and g index (both account for highly cited articles). Spearman correlations were performed between indices and funding. Multivariable linear regression was performed to identify significant independent predictors of funding. For MD investigators: the indices exhibited no-to-weak correlations with funding (r = 0.173-0.387); m quotient exhibited the largest correlation and was the only significant (albeit weak) independent predictor of funding (P = 0.011). For PhD investigators: correlation with funding was weak for m quotient (r = 0.323), although moderate for other indices (r = 0.518-0.568); publication count exhibited highest correlation; publication count (P < 0.001) and hc index (P = 0.024) were significant independent predictors of funding. Bibliometric indices were more strongly associated with grant funding for PhD than for MD radiology investigators, with publication count exhibiting the strongest association in the latter group. Time-weighted adjustments, as reflected by the m quotient and hc index, may improve efforts to predict funding using bibliometrics. Copyright © 2016 The Association of University Radiologists.

Pitt, Catherine; Goodman, Catherine; Hanson, Kara

2016-02-01

We present a bibliometric analysis of recently published full economic evaluations of health interventions and reflect critically on the implications of our findings for this growing field. We created a database drawing on 14 health, economic, and/or general literature databases for articles published between 1 January 2012 and 3 May 2014 and identified 2844 economic evaluations meeting our criteria. We present findings regarding the sensitivity, specificity, and added value of searches in the different databases. We examine the distribution of publications between countries, regions, and health areas studied and compare the relative volume of research with disease burden. We analyse authors' country and institutional affiliations, journals and journal type, language, and type of economic evaluation conducted. More than 1200 economic evaluations were published annually, of which 4% addressed low-income countries, 4% lower-middle-income countries, 14% upper-middle-income countries, and 83% high-income countries. Across country income levels, 53, 54, 86, and 100% of articles, respectively, included an author based in a country within the income level studied. Biomedical journals published 74% of economic evaluations. The volume of research across health areas correlates more closely with disease burden in high-income than in low-income and middle-income countries. Our findings provide an empirical basis for further study on methods, research prioritization, and capacity development in health economic evaluation. © 2016 The Authors.

Miwa, Sayaka; Ando, Satoko

Research fronts analysis identifies emerging areas of research through observing co-clustering in highly-cited papers. This article introduces the concept of research fronts analysis, explains its methodology and provides case examples. It also demonstrates developing research fronts in Japan by looking at the past winners of Thomson Reuters Research Fronts Awards. Research front analysis is currently being used by the Japanese government to determine new trends in science and technology. Information professionals can also utilize this bibliometric as a research evaluation tool.

The effectiveness of the practice of correction and republication in the biomedical literature

Peterson, Gabriel M

2010-01-01

Objective: This research measures the effectiveness of the practice of correction and republication of invalidated articles in the biomedical literature by analyzing the rate of citation of the flawed and corrected versions of scholarly articles over time. If the practice of correction and republication is effective, then the incidence of citation of flawed versions should diminish over time and increased incidence of citation of the republication should be observed. Methods: This is a bibliometric study using citation analysis and statistical analysis of pairs of flawed and corrected articles in MEDLINE and Web of Science. Results: The difference between citation levels of flawed originals and corrected republications does not approach statistical significance until eight to twelve years post-republication. Results showed substantial variability among bibliographic sources in their provision of authoritative bibliographic information. Conclusions: Correction and republication is a marginally effective biblioremediative practice. The data suggest that inappropriate citation behavior may be partly attributable to author ignorance.

Total Ankle Arthroplasty (TAA) is a relatively new and evolving field in Foot and Ankle surgery. We conducted a citation analysis to identify the characteristics of the top 50 most cited articles on total ankle arthroplasty. Using the Web of Science database and the search strategy total ankle arthroplasty OR total ankle replacement , we identified 2445 articles. After filtering for relevant articles, the top 50 cited articles on total ankle arthroplasty were retrieved for descriptive and statistical analysis. The publication years ranged from 1979 to 2013. USA was the most productive country in terms of research output, followed by the UK. Though citation analysis has its flaws, this is a comprehensive list of the top 50 articles significantly impacting literature on total ankle arthroplasty. Based on our study, we conclude that there is marked deficiency of high level articles with respect to the number of citations and future researches need to cater to this question to produce high quality studies.

The editors of Nutrición Hospitalaria (Nutr Hosp) analyze the journal from its foundation in 1979 to the present time, on occasion of the first publication of its impact factorby Journal Citation Reports (JCR). The actions taken along this thirty year period are described, including its incorporation to multiple web databases, the Open Access policy of the journal, its progressive internationality, and the bibliometric analysis made in 1999. A figure with the journal citation trends is included. Nutr Hosp, included in the "Nutrition & Dietetics" group of JCR, is in the position 42/59, i.e. in the third quartile. Among the Spanish journals included in JCR,Nutr Hosp is located in the 14/37 position. A few considerations are made related to the economical aspects of the journal, the number of articles received so far, the articles expected in the future, the rejection rate and the language (Spanish or English) in which Nutr Hosp should be published.

Research productivity assessment is increasingly relevant for allocation of research funds. On one hand, this assessment is challenging because it involves both qualitative and quantitative analysis of several characteristics, most of them subjective in nature. On the other hand, current tools and academic social networks make bibliometric data web-available to everyone for free. Those tools, especially when combined with other data, are able to create a rich environment from which information on research productivity can be extracted. In this context, our work aims at characterizing the Brazilian Computer Science graduate programs and the relationship among themselves. We (i) present views of the programs from different perspectives, (ii) rank the programs according to each perspective and a combination of them, (iii) show correlation between assessment metrics, (iv) discuss how programs relate to another, and (v) infer aspects that boost programs' research productivity. The results indicate that programs with a higher insertion in the coauthorship network topology also possess a higher research productivity between 2004 and 2009.

The paper explores the current state of generalist search education in library schools and considers that foundation in respect to the Medical Library Association's statement on expert searching. Syllabi from courses with significant searching components were examined from ten of the top library schools, as determined by the U.S. News & World Report rankings. Mixed methods were used, but primarily quantitative bibliometric methods were used. The educational focus in these searching components was on understanding the generalist searching resources and typical users and on performing a reflective search through application of search strategies, controlled vocabulary, and logic appropriate to the search tool. There is a growing emphasis on Web-based search tools and a movement away from traditional set-based searching and toward free-text search strategies. While a core set of authors is used in these courses, no core set of readings is used. While library schools provide a strong foundation, future medical librarians still need to take courses that introduce them to the resources, settings, and users associated with medical libraries. In addition, as more emphasis is placed on Web-based search tools and free-text searching, instructors of the specialist medical informatics courses will need to focus on teaching traditional search methods appropriate for common tools in the medical domain.

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

Disseminating information derived from systematic reviews is a fundamental step for translating evidence into practice. To determine which features of dermatological SR are associated with systematic review dissemination, using citation rates as an indicator. Dermatological systematic reviews published between 2008 and 2012 were obtained from Scopus, the ISI Web of Sciences and the Cochrane Skin Group. Bibliometric data of every systematic review were collected and analyzed. A total of 320 systematic reviews were analyzed. Univariable analysis showed that the journal impact factor, number of authors, and total references cited were positively associated with the number of citations. There was a significant difference in the median number of citations with regard to the corresponding author's country, type of skin disease, type of funding, and presence of international collaboration. Cochrane reviews were significantly associated with a lower number of citations. Multivariable analysis found that the number of authors, number of references cited and the corresponding author from United Kingdom were independently correlated with many citations. Cochrane systematic reviews tended to be independently associated with a lower number of citations. Citation number to systematic reviews may be improving by increasing the number of authors, especially collaborative authors, and the number of cited references. The reasons for the association of Cochrane SRs with fewer citations should be addressed in future studies.

The aim of this study was to map an academic hospital's nursing contributions to the literature using bibliometric methods. Nurse executives continue to search for ways to share knowledge gained in the clinical setting. Manuscripts from clinical nurses must increase to advance the science of nursing practice and nursing administration. A search of electronic databases and curriculum vitae provided bibliographic data for University of Colorado Hospital (UCH) nurses from 1990 to 2012. Bibliometric techniques were used for publication counts and citation analysis. A review of the infrastructure supporting scholarly work was undertaken. A total of 191 journal articles, 9 books, 103 book chapters, 5 manuals, and 46 manual chapters were published by UCH nurses. Author productivity steadily increased. Citation analysis indicated that the works published were used by others. The h-index for UCH authors was 25. The hospital culture, interdisciplinary practice, and the role of the research nurse scientists had an impact on study results.

Rational analyses of information foraging on the web.

2005-05-06

This article describes rational analyses and cognitive models of Web users developed within information foraging theory. This is done by following the rational analysis methodology of (a) characterizing the problems posed by the environment, (b) developing rational analyses of behavioral solutions to those problems, and (c) developing cognitive models that approach the realization of those solutions. Navigation choice is modeled as a random utility model that uses spreading activation mechanisms that link proximal cues (information scent) that occur in Web browsers to internal user goals. Web-site leaving is modeled as an ongoing assessment by the Web user of the expected benefits of continuing at a Web site as opposed to going elsewhere. These cost-benefit assessments are also based on spreading activation models of information scent. Evaluations include a computational model of Web user behavior called Scent-Based Navigation and Information Foraging in the ACT Architecture, and the Law of Surfing, which characterizes the empirical distribution of the length of paths of visitors at a Web site. 2005 Lawrence Erlbaum Associates, Inc.

Ebola virus disease (hereafter EVD or Ebola) has a high fatality rate. The devastating effects of the current epidemic of Ebola in West Africa have put the global health response in acute focus. In response, the World Health Organization (WHO) has declared the Ebola outbreak in West Africa as a "Public Health Emergency of International Concern". A small proportion of scientific literature is dedicated to Ebola research. To identify global research trends in Ebola research, the Institute for Scientific Information (ISI) Web of Science™ database was used to search for data, which encompassed original articles published from 1900 to 2013. The keyword "Ebola" was used to identify articles for the purposes of this review. In order to include all published items, the database was searched using the Basic Search method. The earliest record of literature about Ebola indexed in the Web of Science is from 1977. A total of 2477 publications on Ebola, published between 1977 and 2014 (with the number of publications increasing annually), were retrieved from the database. Original research articles (n = 1623, 65.5%) were the most common type of publication. Almost all (96.5%) of the literature in this field was in English. The USA had the highest scientific output and greatest number of funding agencies. Journal of Virology published 239 papers on Ebola, followed by Journal of Infectious Diseases and Virology, which published 113 and 99 papers, respectively. A total of 1911 papers on Ebola were cited 61,477 times. This analysis identified the current state of research and trends in studies about Ebola between 1977 and 2014. Our bibliometric analysis provides a historical perspective on the progress in Ebola research.

The Top 50 Articles on Minimally Invasive Spine Surgery.

2017-04-01

Bibliometric study of current literature. To catalog the most important minimally invasive spine (MIS) surgery articles using the amount of citations as a marker of relevance. MIS surgery is a relatively new tool used by spinal surgeons. There is a dynamic and evolving field of research related to MIS techniques, clinical outcomes, and basic science research. To date, there is no comprehensive review of the most cited articles related to MIS surgery. A systematic search was performed over three widely used literature databases: Web of Science, Scopus, and Google Scholar. There were four searches performed using the terms "minimally invasive spine surgery," "endoscopic spine surgery," "percutaneous spinal surgery," and "lateral interbody surgery." The amount of citations included was averaged amongst the three databases to rank each article. The query of the three databases was performed in November 2015. Fifty articles were selected based upon the amount of citations each averaged amongst the three databases. The most cited article was titled "Extreme Lateral Interbody Fusion (XLIF): a novel surgical technique for anterior lumbar interbody fusion" by Ozgur et al and was credited with 447, 239, and 279 citations in Google Scholar, Web of Science, and Scopus, respectively. Citations ranged from 27 to 239 for Web of Science, 60 to 279 for Scopus, and 104 to 462 for Google Scholar. There was a large variety of articles written spanning over 14 different topics with the majority dealing with clinical outcomes related to MIS surgery. The majority of the most cited articles were level III and level IV studies. This is likely due to the relatively recent nature of technological advances in the field. Furthermore level I and level II studies are required in MIS surgery in the years ahead. 5.

INTRODUCTION: The present study was motivated by the need to systematically assess the research productivity of the Heart Institute (InCor), Medical School of the University of São Paulo, Brazil. OBJECTIVE: To explore methodology for the assessment of institutional scientific research productivity. MATERIALS AND METHODS: Bibliometric indicators based on searches for author affiliation of original scientific articles or reviews published in journals indexed in the databases Web of Science, MEDLINE, EMBASE, LILACS and SciELO from January 2000 to December 2003 were used in this study. The retrieved records were analyzed according to the index parameters of the journals and modes of access. The number of citations was used to calculate the institutional impact factor. RESULTS: Out of 1253 records retrieved from the five databases, 604 original articles and reviews were analyzed; of these, 246 (41%) articles were published in national journals and 221 (90%) of those were in journals with free online access through SciELO or their own websites. Of the 358 articles published in international journals, 333 (93%) had controlled online access and 223 (67%) were available through the Capes Portal of Journals. The average impact of each article for InCor was 2.224 in the period studied. CONCLUSION: A simple and practical methodology to evaluate the scientific production of health research institutions includes searches in the LILACS database for national journals and in MEDLINE and the Web of Science for international journals. The institutional impact factor of articles indexed in the Web of Science may serve as a measure by which to assess and review the scientific productivity of a research institution. PMID:19578662

Objective We have carried out a bibliometric study on the scientific publications in relation to atypical or second-generation antipsychotic drugs (SGAs) in South Korea. Methods With the EMBASE and MEDLINE databases, we selected those publications made in South Korea whose title included the descriptors atypic* (atypical*) antipsychotic*, second-generation antipsychotic*, clozapine, risperidone, olanzapine, ziprasidone, quetiapine, sertindole, aripiprazole, paliperidone, amisulpride, zotepine, asenapine, iloperidone, lurasidone, perospirone and blonanserin. We applied some bibliometric indicators of paper production and dispersion with Price's law and Bradford's law, respectively. We also calculated the participation index (PI) of the different countries, and correlated the bibliometric data with some social and health data from Korea (such as total per capita expenditure on health and gross domestic expenditure on research and development). Results We collected 326 original papers published between 1993 and 2011. Our results state fulfilment of fulfilled Price's law, with scientific production on SGAs showing exponential growth (correlation coefficient r=0.8978, as against an r=0.8149 after linear adjustment). The most widely studied drugs were risperidone (91 papers), aripiprazole (77), olanzapine (53), and clozapine (43). Division into Bradford zones yielded a nucleus occupied by the Progress in Neuro-Psychopharmacology and Biological Psychiatry (36 articles). A total of 86 different journals were published, with 4 of the first 10 used journals having an impact factor being greater than 4. Conclusion The publications on SGAs in South Korea have undergone exponential growth over the studied period, without evidence of reaching a saturation point. PMID:23482954

The study presents the bibliometric analysis of the Spanish scientific output in biomedicine during 1996-2004. This is the last edition of a series of bibliometric studies aimed to characterize the Spanish scientific performance in biomedicine. The analysis was restricted to citable documents for which simple and composite bibliometric indicators were obtained at different aggregation levels: fields, autonomous regions, institutional sectors and research centres. The documents were selected according to the Journal Citation Reports, and were assigned to affiliation centres following an integer counting scheme after an exhaustive normalization of the affiliation addresses. Compared to the period 1994-2002, research activity in biomedicine grew as much as Spain: 8.9% in the number of documents; 22.5% citations; 12.5% citation per document average and 27.2% international cooperation. Besides, biomedicine showed the highest citation per document average compared to other major fields. International cooperation in biomedicine (27.2%) reached the European average. The documents published in international cooperation account for the half of citations to documents in biomedicine. The number of documents and citations belonging to the clinic medicine subfield and to the health sector showed the highest growth. In general, these results reproduce the tendencies described in prior studies. The documents in biomedicine showed a highly asymmetric distribution among institutional sectors, autonomous regions, scientific fields and research centres. The remarkably increase in the output of clinical medicine field and in the health sector could be the consequence of important science policy actions undertaken in these areas in the last years.

The "Mendel syndrome" in science: durability of scientific literature and its effects on bibliometric analysis of individual scientists.

2011-10-01

The obsolescence and "durability" of scientific literature have been important elements of debate during many years, especially regarding the proper calculation of bibliometric indicators. The effects of "delayed recognition" on impact indicators have importance and are of interest not only to bibliometricians but also among research managers and scientists themselves. It has been suggested that the "Mendel syndrome" is a potential drawback when assessing individual researchers through impact measures. If publications from particular researchers need more time than "normal" to be properly acknowledged by their colleagues, the impact of these researchers may be underestimated with common citation windows. In this paper, we answer the question whether the bibliometric indicators for scientists can be significantly affected by the Mendel syndrome. Applying a methodology developed previously for the classification of papers according to their durability (Costas et al., J Am Soc Inf Sci Technol 61(8):1564-1581, 2010a; J Am Soc Inf Sci Technol 61(2):329-339, 2010b), the scientific production of 1,064 researchers working at the Spanish Council for Scientific Research (CSIC) in three different research areas has been analyzed. Cases of potential "Mendel syndrome" are rarely found among researchers and these cases do not significantly outperform the impact of researchers with a standard pattern of reception in their citations. The analysis of durability could be included as a parameter for the consideration of the citation windows used in the bibliometric analysis of individuals.

Given the well documented undesired impacts of HIV/AIDS globally, there is a need to create a statistical inventory of research output on HIV/AIDS. This need is particularly important for a country such as Lesotho, whose HIV/AIDS prevalence is one of the highest globally. Research on HIV/AIDS in sub-Saharan Africa continues to trail behind that of other regions, especially those of the developed countries. Lesotho, a sub-Saharan country, is a developing country with lower research output in this area when longitudinally compared to other countries. This study reviewed the volume and scope of the general research output on HIV/AIDS in Lesotho and assessed the coverage of the national research agenda on HIV/AIDS, making recourse to statistical principles. A bibliometric review of studies on HIV/AIDS retrieved from the SCOPUS and PubMed databases, published within the 30-year period between 1985 and 2016, was conducted. The focus of each of the studies was analysed and the studies were cross-matched with the national research agenda in accordance with bibliometric methodologies. In total, 1280 studies comprising 1181 (92.3%) journal articles, 91 (7.1%) books and 8 (0.6%) conference proceedings were retrieved. By proportion, estimation of burden of infection (40.7%) had the highest research volume, while basic (5.5%) and preventive measures (24.4%) and national planning (29.4%) had the lowest. Out of the total studies retrieved, only 516 (40.3%) matched the national research agenda. Research on maternal and child health quality of care, viral load point-of-care devices, and infant point-of-care diagnosis had hardly any publications in the high priority research category of the agenda. Notwithstanding a considerable research output on HIV/AIDS for Lesotho, there is insufficient coverage of the national research agenda in this research area. The major research gaps on general research output are in basic and preventive measures as well as national planning. There is also a need to increase targeted funding for HIV/AIDS research to appropriately address the most compelling gaps and national needs.

A bibliometric analysis of toxicology research productivity in Middle Eastern Arab countries during a 10-year period (2003–2012)

PubMed Central

2014-01-01

Background Bibliometric studies are increasingly being used for research assessment by involving the application of statistical methods to scientific publications to obtain the bibliographics for each country. The main objective of this study was to analyse the research productivity originating from 13 Middle Eastern Arab (MEA) countries with articles published in toxicology journals. Methods Data from January 1, 2003 till December 31, 2012 were searched for documents with specific words in the toxicology field as a “source title” in any one of the 13 MEA countries. Research productivity was evaluated based on a methodology developed and used in other bibliometric studies. Research productivity was adjusted to the national population and nominal gross domestic product (GDP) per capita. Results Documents (n = 1,240) were retrieved from 73 international peer-reviewed toxicology journals. The h-index of the retrieved documents was 39. Of the 73 journal titles, 52 (69.9%) have their IF listed in the ISI Journal Citation Reports 2012; 198 documents (16.0%) were published in journals that had no official IF. After adjusting for economy and population power, Egypt (193.6), Palestine (18.1), Kingdom of Saudi Arabia (KSA) (13.0), and Jordan (11.5) had the highest research productivity. Countries with large economies, such as the Kuwait, United Arab Emirates (UAE), and Oman, tended to rank relatively low after adjustment of GDP. The total number of citations at the time of data analysis (August 4, 2013) was 10,991, with a median (interquartile range) of 4 (1–11). MEA collaborated more with countries in the MEA regions (16.7%), especially KSA, Egypt, and UAE, followed by Europe (14.4%), especially with the United Kingdom and Germany. Conclusions The present data show a promising rise and a good start for toxicology research activity in toxicology journals in the Arab world. Research output is low in some countries, which can be improved by investing in more international and national collaborative research projects in the field of toxicology. PMID:24443999

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

The Internet has become an established source of health information for people seeking health information. In recent years, research on the health information seeking behavior of Internet users has become an increasingly important scholarly focus. However, there have been no long-term bibliometric studies to date on Internet health information seeking behavior. The purpose of this study was to map publication trends and explore research hot spots of Internet health information seeking behavior. A bibliometric analysis based on PubMed was conducted to investigate the publication trends of research on Internet health information seeking behavior. For the included publications, the annual publication number, the distribution of countries, authors, languages, journals, and annual distribution of highly frequent major MeSH (Medical Subject Headings) terms were determined. Furthermore, co-word biclustering analysis of highly frequent major MeSH terms was utilized to detect the hot spots in this field. A total of 533 publications were included. The research output was gradually increasing. There were five authors who published four or more articles individually. A total of 271 included publications (50.8%) were written by authors from the United States, and 516 of the 533 articles (96.8%) were published in English. The eight most active journals published 34.1% (182/533) of the publications on this topic. Ten research hot spots were found: (1) behavior of Internet health information seeking about HIV infection or sexually transmitted diseases, (2) Internet health information seeking behavior of students, (3) behavior of Internet health information seeking via mobile phone and its apps, (4) physicians' utilization of Internet medical resources, (5) utilization of social media by parents, (6) Internet health information seeking behavior of patients with cancer (mainly breast cancer), (7) trust in or satisfaction with Web-based health information by consumers, (8) interaction between Internet utilization and physician-patient communication or relationship, (9) preference and computer literacy of people using search engines or other Web-based systems, and (10) attitude of people (especially adolescents) when seeking health information via the Internet. The 10 major research hot spots could provide some hints for researchers when launching new projects. The output of research on Internet health information seeking behavior is gradually increasing. Compared to the United States, the relatively small number of publications indexed by PubMed from other developed and developing countries indicates to some extent that the field might be still underdeveloped in many countries. More studies on Internet health information seeking behavior could give some references for health information providers.

Web Crawling has acquired tremendous significance in recent times and it is aptly associated with the substantial development of the World Wide Web. Web Search Engines face new challenges due to the availability of vast amounts of web documents, thus making the retrieved results less applicable to the analysers. However, recently, Web Crawling solely focuses on obtaining the links of the corresponding documents. Today, there exist various algorithms and software which are used to crawl links from the web which has to be further processed for future use, thereby increasing the overload of the analyser. This paper concentrates on crawling the links and retrieving all information associated with them to facilitate easy processing for other uses. In this paper, firstly the links are crawled from the specified uniform resource locator (URL) using a modified version of Depth First Search Algorithm which allows for complete hierarchical scanning of corresponding web links. The links are then accessed via the source code and its metadata such as title, keywords, and description are extracted. This content is very essential for any type of analyser work to be carried on the Big Data obtained as a result of Web Crawling.

Sales, Gabriele; Calura, Enrica; Martini, Paolo; Romualdi, Chiara

2013-01-01

Graphite web is a novel web tool for pathway analyses and network visualization for gene expression data of both microarray and RNA-seq experiments. Several pathway analyses have been proposed either in the univariate or in the global and multivariate context to tackle the complexity and the interpretation of expression results. These methods can be further divided into ‘topological’ and ‘non-topological’ methods according to their ability to gain power from pathway topology. Biological pathways are, in fact, not only gene lists but can be represented through a network where genes and connections are, respectively, nodes and edges. To this day, the most used approaches are non-topological and univariate although they miss the relationship among genes. On the contrary, topological and multivariate approaches are more powerful, but difficult to be used by researchers without bioinformatic skills. Here we present Graphite web, the first public web server for pathway analysis on gene expression data that combines topological and multivariate pathway analyses with an efficient system of interactive network visualizations for easy results interpretation. Specifically, Graphite web implements five different gene set analyses on three model organisms and two pathway databases. Graphite Web is freely available at http://graphiteweb.bio.unipd.it/.

The quality of systematic reviews and meta-analyses on psoriasis, a chronic inflammatory skin disease that severely impairs quality of life and is associated with high costs, remains unknown. To assess the methodological quality of systematic reviews published on psoriasis. After a comprehensive search in MEDLINE, Embase and the Cochrane Database (PROSPERO: CDR42016041611), the quality of studies was assessed by two raters using the Assessment of Multiple Systematic Reviews (AMSTAR) tool. Article metadata and journal-related bibliometric indices were also obtained. Systematic reviews were classified as low (0-4), moderate (5-8) or high (9-11) quality. A prediction model for methodological quality was fitted using principal component and multivariate ordinal logistic regression analyses. We classified 220 studies as high (17·2%), moderate (55·0%) or low (27·8%) quality. Lower compliance rates were found for AMSTAR question (Q)5 (list of studies provided, 11·4%), Q10 (publication bias assessed, 27·7%), Q4 (status of publication included, 39·5%) and Q1 (a priori design provided, 40·9%). Factors such as meta-analysis inclusion [odds ratio (OR) 6·22; 95% confidence interval (CI) 2·78-14·86], funding by academic institutions (OR 2·90, 95% CI 1·11-7·89), Article Influence score (OR 2·14, 95% CI 1·05-6·67), 5-year impact factor (OR 1·34, 95% CI 1·02-1·40) and article page count (OR 1·08, 95% CI 1·02-1·15) significantly predicted higher quality. A high number of authors with a conflict of interest (OR 0·90, 95% CI 0·82-0·99) was significantly associated with lower quality. The methodological quality of systematic reviews published about psoriasis remains suboptimal. The type of funding sources and author conflicts may compromise study quality, increasing the risk of bias. © 2017 British Association of Dermatologists.

To provide an in-depth evaluation of research yield in laryngeal cancer from 1945 to 2010, using large-scale data analysis, employment of bibliometric indicators of production and quality, and density equalizing mapping. Bibliometic analysis incorporating the Web of Science Database. The search strategy employed was as follows; "TS = ((Laryngeal Neoplasm$) OR (Larynx Neoplasm$) OR (Larynx Cancer$) OR (Laryngeal Cancer$))." Author and journal data and cooperation networks were computed following analysis of combinations of countries and institutions that registered cooperation during the study period. Mapping was performed as described by Groneberg-Kloft in 2004. A total of 8,658 items relating to laryngeal cancer were published over the study period, accounting for 139,700 citations. The United States was the most prolific country, accounting for 28.83% (n = 2,496) of total output. Other prolific nations included Italy (n = 794) and Germany (n = 792). There were 973 items published as a consequence of international cooperation; this practice increased steadily over time and accounted for 15.58% (88 of 565) of output in 2010. There were 1,073 different journals publishing articles on laryngeal cancer, although the top 20 (1.8%) most prolific titles were together responsible for more than 43% of the total output; these were led by Laryngoscope (n = 368) and Head and Neck, Journal of the Scientific Specialties (n = 364). A total of 24,682 authors contributed to the literature on laryngeal cancer; the leading author by output was Alfio Ferlito (n = 120); Carlo La Vecchia recorded the highest h-index (h = 32). This work represents the first attempt to provide quantitative and qualitative analysis of laryngeal cancer research output, whilst in tandem identifying the key bibliometric benchmarks to which those involved in the production of that output might aspire.

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.

The number of citations that a research paper receives can be used as a measure of its scientific impact. The objective of this study was to identify and to examine the characteristics of top 100 cited articles in the field of Medical Informatics based on data acquired from the Thomson Reuters' Web of Science (WOS) in October, 2016. The data was collected using two procedures: first we included articles published in the 24 journals listed in the "Medical Informatics" category; second, we retrieved articles using the key words: "informatics", "medical informatics", "biomedical informatics", "clinical informatics" and "health informatics". After removing duplicate records, articles were ranked by the number of citations they received. When the 100 top cited articles had been identified, we collected the following information for each record: all WOS database citations, year of publication, journal, author names, authors' affiliation, country of origin and topics indexed for each record. Citations for the top 100 articles ranged from 346 to 7875, and citations per year ranged from 11.12 to 525. The majority of articles were published in the 2000s (n=43) and 1990s (n=38). Articles were published across 10 journals, most commonly Statistics in medicine (n=71) and Medical decision making (n=28). The articles had an average of 2.47 authors. Statistics and biostatistics modeling was the most common topic (n=71), followed by artificial intelligence (n=12), and medical errors (n=3), other topics included data mining, diagnosis, bioinformatics, information retrieval, and medical imaging. Our bibliometric analysis illustrated a historical perspective on the progress of scientific research on Medical Informatics. Moreover, the findings of the current study provide an insight on the frequency of citations for top cited articles published in Medical Informatics as well as quality of the works, journals, and the trends steering Medical Informatics.

2017-01-01

Background The aim of this study was to assess the scientific output of Spanish universities that offer a bachelor’s degree in dentistry through the use of various bibliometric indicators. Material and Methods A total of 21 universities offered a bachelor’s degree in dentistry in academic year 2016-2017. The search for papers published by authors associated with these institutions was carried out using the selection of journals listed in the Journal Citation Reports (JCR) and the Web of Knowledge database for the period 1986-2017. On the basis of these data, we determined the output, the h-, g- and hg-indexes, the most productive authors, international collaborations, and the most relevant journals. Results Public universities obtained better results than private universities. The University of Valencia was ranked first, followed by the Complutense University of Madrid and the University of Granada. The most productive author was José Vicente Bagán, but the author with the highest h-index was Mariano Sanz and Manuel Toledado. The universities with the greatest output and highest citation rates had more international collaborations. The most developed fields in Spanish universities were Oral surgery, Oral medicine and Dental materials. The universities had different models of production. At universities such as Barcelona or Valencia, the production was focused on very few departments and authors. At the other extreme, the University of Granada had various sources of research and authors, which meant that its output and citation rate could increase more. Conclusions University faculties must provide suitable academic and research training, and therefore must be assessed using objective criteria and bibliometric tools. Although the number of university schools and faculties that teach dentistry has increased, and particularly the number of private universities, there is no correlation between their quality and output and the number of places offered on their courses. Key words:Dentistry, h-index, impact factor, universities, Spain. PMID:28624836

Background Cardiovascular research output and citations of publications from Africa have historically been low yet may be increasing. However, data from the continent are limited. Methods and Results To evaluate the cardiovascular research output and citations from 52 African countries between 1999 and 2008, we created a bibliometric filter to capture cardiovascular research articles published in the Web of Knowledge based on specialist journals and title words. Two coauthors with expertise in cardiovascular medicine tested and refined this filter to achieve >90% precision and recall. We matched retrieved records with their associated citation reports and calculated the running 5‐year citation count postpublication, including the year of publication. Publications from Africa were identified by author addresses. South Africa published 872 cardiovascular research papers, Egypt 393, Tunisia 264, and Nigeria 192 between 1999 and 2008. The number of publications increased over the time period for a small number of countries (range 0.1 to 4.8 more publications per year by fractional count). Most countries' citations were low (<50), but citations were greatest for South Africa (7063), Egypt (2557), Tunisia (903), and Nigeria (540). The same countries had the greatest annual increase in 5‐year citation index values: 65 (95% CI: 30, 99) for South Africa, 46 (34, 58) for Egypt, 22 (15, 28) for Tunisia, and 8 (2, 14) for Nigeria. The burden of cardiovascular disease had a weak and inconsistent relationship to cardiovascular publications (r2=0.07, P=0.05). Greater gross domestic product was associated with more cardiovascular publications in 2008 (r2=0.53, P<0.0001). Conclusions The increases in cardiovascular research outputs from Africa are concentrated in a few countries. The reasons for regional differences in research outputs require further investigation, particularly relative to competing disease burdens. Higher prioritization of cardiovascular research funding from African countries is warranted. PMID:25836056

Introduction Diabetes Mellitus (DM) is a huge burden for human health. Recent studies show the close relationship between DM and T cells. We investigated the trend in DM and T cells research. Methods Using the Web of Science database, we searched the publications on DM and T cells in 1997–2016, and studied the source data using bibliometric methodology. Excel 2016, GraphPad Prism 5, and VOSviewer software were used to analyze the publication trend in DM and T cells research. Results We found a total of 1077 publications with 38109 citations up to January 23, 2017. The highest contribution came from the United States, with 48.38% of the publications, 61.44% of the citations and the highest H-index (74). China had the 5th place for total publications, but ranked 11th both for citation frequency (604) and H-index (13). The inflection point of the global DM and T cells publications was in 2000. Journal of Immunology published the most related articles (164). Santamaria P. was the leading scholar in this field with the most publications (35). The keywords “regulatory T cell” and “autoimmune diabetes” were mentioned more than 300 times. Furthermore, type 2 (T2)DM, T cell immunoglobulin and mucin domain (TIM) and obesity are becoming popular research topics in this field. Conclusion The quantity of publications on DM and T cells grew rapidly around year 2000, but has relatively decreased recently. The United States had the leading position in global research. There was a discrepancy between productivity and quality of publications from China. Latest progress is most likely first published by the Journal of Immunology. Santamaria P., Roep B.O. and Peakman M. were the pioneer scholars in this field. Most researchers have focused on “regulatory T cell” and “autoimmune diabetes” research. In future, T2DM, TIM and obesity may be the popular areas. PMID:28926600

A bibliometric analysis of the UK National Institute for Health Research (NIHR) Health Technology Assessment (HTA) monographs and their related journal articles by: (1) exploring the differences in citations to the HTA monographs in Google Scholar (GS), Scopus and Web of Science (WoS), and (2) comparing Scopus citations to the monographs with their related journal articles. A study of 111 HTA monographs published in 2010 and 2011, and their external journal articles. Citations to the monographs in GS, Scopus and WoS, and to their external journal articles in Scopus. The number of citations varied among the three databases, with GS having the highest and WoS the lowest; however, the citation-based rankings among the databases were highly correlated. Overall, 56% of monographs had a related publication, with the highest proportion for primary research (76%) and lowest for evidence syntheses (43%). There was a large variation in how the monographs were cited, compared to journal articles, resulting in more frequent problems, with unlinked citations in Scopus and WoS. When comparing differences in the number of citations between monograph publications with their related journal articles from the same project, we found that monographs received more citations than their journal articles for evidence syntheses and methodology projects; by contrast, journal articles related to primary research monographs were more highly cited than their monograph. The numbers of citations to the HTA monographs differed considerably between the databases, but were highly correlated. When a HTA monograph had a journal article from the same study, there were more citations to the journal article for primary research, but more to the monographs for evidence syntheses. Citations to the related journal articles were more reliably recorded than citations to the HTA monographs. Published by the BMJ Publishing Group Limited.

Human space exploration (HSE) is an interdisciplinary field composed of a range of subjects that have developed dramatically over the last few decades. This paper investigates the intellectual structure of HSE research with a focus on human related factors. A bibliometric approach with quantitative analytical techniques is applied to study the development and growth of the research. This study retrieves 1921 papers on HSE related to human factors from the year 1990 to the year 2016 from Web of Science and constructs a critical citation network composed of 336 papers. Edge-betweenness-based clustering is used to classify the citation network into twelve distinct research clusters based on four research themes: "biological risks from space radiation," "health and performance during long-duration spaceflight," "program and in-situ resources for HSE missions," and "habitat and life support systems in the space environment." These research themes are also similar to the classification results of a co-occurrence analysis on keywords for a total of 1921 papers. Papers with high centrality scores are identified as important papers in terms of knowledge flow. Moreover, the intermediary role of papers in exchanging knowledge between HSE sub-areas is identified using brokerage analysis. The key-route main path highlights the theoretical development trajectories. Due to the recent dramatic increase in investment by international governments and the private sector, the theoretical development trajectories of key research themes have been expanding from furthering scientific and technical knowledge to include various social and economic issues, thus encouraging massive public participation. This study contributes to an understanding of research trends and popular issues in the field of HSE by introducing a powerful way of determining major research themes and development trajectories. This study will help researchers seek the underlying knowledge diffusion flow from multifaceted aspects to establish future research directions.

Media Effects: Theory and Research.

This review analyzes trends and commonalities among prominent theories of media effects. On the basis of exemplary meta-analyses of media effects and bibliometric studies of well-cited theories, we identify and discuss five features of media effects theories as well as their empirical support. Each of these features specifies the conditions under which media may produce effects on certain types of individuals. Our review ends with a discussion of media effects in newer media environments. This includes theories of computer-mediated communication, the development of which appears to share a similar pattern of reformulation from unidirectional, receiver-oriented views, to theories that recognize the transactional nature of communication. We conclude by outlining challenges and promising avenues for future research.

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

Compilation and network analyses of cambrian food webs.

Dunne, Jennifer A; Williams, Richard J; Martinez, Neo D; Wood, Rachel A; Erwin, Douglas H

2008-04-29

A rich body of empirically grounded theory has developed about food webs--the networks of feeding relationships among species within habitats. However, detailed food-web data and analyses are lacking for ancient ecosystems, largely because of the low resolution of taxa coupled with uncertain and incomplete information about feeding interactions. These impediments appear insurmountable for most fossil assemblages; however, a few assemblages with excellent soft-body preservation across trophic levels are candidates for food-web data compilation and topological analysis. Here we present plausible, detailed food webs for the Chengjiang and Burgess Shale assemblages from the Cambrian Period. Analyses of degree distributions and other structural network properties, including sensitivity analyses of the effects of uncertainty associated with Cambrian diet designations, suggest that these early Paleozoic communities share remarkably similar topology with modern food webs. Observed regularities reflect a systematic dependence of structure on the numbers of taxa and links in a web. Most aspects of Cambrian food-web structure are well-characterized by a simple "niche model," which was developed for modern food webs and takes into account this scale dependence. However, a few aspects of topology differ between the ancient and recent webs: longer path lengths between species and more species in feeding loops in the earlier Chengjiang web, and higher variability in the number of links per species for both Cambrian webs. Our results are relatively insensitive to the exclusion of low-certainty or random links. The many similarities between Cambrian and recent food webs point toward surprisingly strong and enduring constraints on the organization of complex feeding interactions among metazoan species. The few differences could reflect a transition to more strongly integrated and constrained trophic organization within ecosystems following the rapid diversification of species, body plans, and trophic roles during the Cambrian radiation. More research is needed to explore the generality of food-web structure through deep time and across habitats, especially to investigate potential mechanisms that could give rise to similar structure, as well as any differences.

[Confusing the confused: thoughts on impact factor, h(irsch) index, Q value, and other cofactors that influence the researcher's happiness].

2009-06-30

The need to evaluate curricula for sponsorship for research projects or professional promotion, has led to the search for tools that allow an objective valuation. However, the total number papers published, or citations of articles of a particular author, or the impact factor of the Journal where they are published are inadequate indicators for the evaluation of the quality and productivity of researchers. The h index, proposed by Hirsch, categorises the papers according to the number of citations per article. This tool appears to lack the limitations of other bibliometric tools but is less useful for non English-speaking authors. To propose and debate the usefulness of the existing bibliometric indicators and tools for the evaluation and categorization of researchers and scientific journals. Search for papers on bibliometric tools. There are some hot spots in the debate on the national and international evaluation of researchers' productivity and quality of scientific journals. Opinions on impact factors and h index have been discussed. The positive discrimination, using the Q value, is proposed as an alternative for the evaluation of Spanish and Iberoamerican researchers. It is very important de-mystify the importance of bibliometric indicators. The impact factor is useful for evaluating journals from the same scientific area but not for the evaluation of researchers' curricula. For the comparison of curricula from two or more researchers, we must use the h index or the proposed Q value. the latter allows positive discrimination of the task for Spanish and Iberoamerican researchers.

Bibliometrics is defined as the study of statistical and mathematical methods used to quantitatively analyze scientific literature. The application of bibliometrics in neurosurgery continues to evolve. To calculate a number of publication productivity measures for almost all neurosurgical residents and departments within North America. These measures were correlated with survey results on the educational environment within residency programs. During May to June 2017, data were collected from departmental websites and Scopus to compose a bibliometric database of neurosurgical residents and residency programs. Data related to authorship value and study content were collected on all articles published by residents. A survey of residency program research and educational environment was administered to program directors and coordinators; results were compared with resident academic productivity. The median number of publications in residency was 3; median h-index and Resident index were 1 and 0.17 during residency, respectively. There was a statistically significant difference in academic productivity among male neurosurgical residents compared with females. The majority of articles published were tier 1 clinical articles. Residency program research support was significantly associated with increased resident productivity (P < .001). Scholarly activity requirements were not associated with increased resident academic productivity. This study represents the most comprehensive bibliometric assessment of neurosurgical resident academic productivity during training to date. New benchmarks for individual and department academic productivity are provided. A supportive research environment for neurosurgical residents is associated with increased academic productivity, but a scholarly activity requirement was, surprisingly, not shown to have a positive effect.

Harmonic Allocation of Authorship Credit: Source-Level Correction of Bibliometric Bias Assures Accurate Publication and Citation Analysis

PubMed Central

Hagen, Nils T.

2008-01-01

Authorship credit for multi-authored scientific publications is routinely allocated either by issuing full publication credit repeatedly to all coauthors, or by dividing one credit equally among all coauthors. The ensuing inflationary and equalizing biases distort derived bibliometric measures of merit by systematically benefiting secondary authors at the expense of primary authors. Here I show how harmonic counting, which allocates credit according to authorship rank and the number of coauthors, provides simultaneous source-level correction for both biases as well as accommodating further decoding of byline information. I also demonstrate large and erratic effects of counting bias on the original h-index, and show how the harmonic version of the h-index provides unbiased bibliometric ranking of scientific merit while retaining the original's essential simplicity, transparency and intended fairness. Harmonic decoding of byline information resolves the conundrum of authorship credit allocation by providing a simple recipe for source-level correction of inflationary and equalizing bias. Harmonic counting could also offer unrivalled accuracy in automated assessments of scientific productivity, impact and achievement. PMID:19107201

Web Search Studies: Multidisciplinary Perspectives on Web Search Engines

NASA Astrophysics Data System (ADS)

Zimmer, Michael

Perhaps the most significant tool of our internet age is the web search engine, providing a powerful interface for accessing the vast amount of information available on the world wide web and beyond. While still in its infancy compared to the knowledge tools that precede it - such as the dictionary or encyclopedia - the impact of web search engines on society and culture has already received considerable attention from a variety of academic disciplines and perspectives. This article aims to organize a meta-discipline of “web search studies,” centered around a nucleus of major research on web search engines from five key perspectives: technical foundations and evaluations; transaction log analyses; user studies; political, ethical, and cultural critiques; and legal and policy analyses.

To analyse the institutionalisation of nutrition sciences in Spain in the second half of the twentieth century, and evaluate the activities of the journal Anales de Bromatología. Descriptive bibliometric study of the original articles. Full names of the authors and the complete article title were recorded. Using key words, each article was assigned by consensus of the researchers to a single main subject in accordance with the thirteen subject areas addressed by the Spanish Society of Bromatology in its meetings. An analysis was conducted of the distribution and trends of general productivity indicators and their characteristics. A total of 917 original articles were published, with a mean of 20.8 papers/year. The subjects for which the highest percentage of articles was recorded were foreign substances in foods, foods of plant origin and nutrition. A total of 874 authors contributed, with a collaboration rate of 2.43 and a transience rate of 70.1%. Distribution of the number of authors per article was close to that indicated by Lotka's law of scientific productivity. The top twelve producers, predominantly women, participated in 49.9% of the articles published. The journal showed low productivity and was of an endogamous nature, with a predominance of authors related to the School of Bromatology in the Faculty of Pharmacy, at the Complutense University. The subjects addressed reflected the demands of the nutrition transition in Spain.

Patient-centred care has been advocated as a key component of high-quality patient care, yet its meanings and related actions have been difficult to ascertain. To map the use of different terms related to the process of giving patients a starring role in their own care and clarify the possible boundaries between terms that are often mixed. A literature search was conducted using different electronic databases. All records containing the search terms 'patient engagement', 'patient activation', 'patient empowerment', 'patient involvement', 'patient adherence', 'patient compliance' and 'patient participation' were collected. Identified literature was then analysed using the Statistical Package for Social Science (SPSS). The number of yearly publications, most productive countries, cross-concepts articles and various scientific fields dealing with the multidisciplinary concepts were identified. Overall, 58 987 papers were analysed. Correspondence analysis revealed three temporal trends. The first period (2002-2004) focused on compliance and adherence, the second period (2006-2009) focused on the relationship between participation and involvement, and the third one (2010-2013) emphasized empowerment. Patient activation and patient engagement followed the temporal development trend connected to the 'immediate future'. The bibliometric trend suggests that the role of patient in the health-care system is changing. In the last years, the patient was viewed as a passive receptor of medical prescription. To date, the need to consider patients as active partners of health-care planning and delivery is growing. In particular, the term patient engagement appears promising, not only for its increasing growth of interest in the scholarly debate, but also because it offers a broader and better systemic conceptualization of the patients' role in the fruition of health care. To build a shared vocabulary of terms and concepts related to the active role of patients in the health-care process may be envisaged as the first operative step towards a concrete innovation of health-care organizations and systems. © 2014 The Authors Health Expectations Published by John Wiley & Sons Ltd.

Considerable time and resources are allocated to carry out qualitative research. The purpose of our study was to evaluate the availability of qualitative research on women's health screening and assess its influence on screening practice guidelines in the United States, Canada, and the United Kingdom. Medline, CINHAL, and WEB of Science databases were used to identify the availability of qualitative research conducted in the past 15 years on 3 different women's health screening topics: cervical cancer screening, breast cancer screening, and prenatal first-trimester screening. Key national practice guidelines on women's health screening were selected using the National Guideline Clearinghouse web site. Bibliometric analysis was used to determine the frequency of qualitative references cited in the guidelines. A total of 272 qualitative research papers on women's health screening was identified: 109 on cervical cancer screening, 104 on breast cancer screening, and 59 on prenatal first-trimester screening. The qualitative studies focused on health care provider perspectives as well as ethical, ethnographic, psychological, and social issues surrounding screening. Fifteen national clinical practice guidelines on women's health screening were identified. A total of 943 references was cited, only 2 of which comprised of qualitative research cited by only 1 clinical practice guideline. Although there is considerable qualitative research that has been carried out on women's health screening, its incorporation into clinical practice guidelines is minimal. Further exploration of the disconnect between the two is important for enhancing knowledge translation of qualitative research within clinical practice. Copyright © 2014 Mosby, Inc.

Quantitative bibliometric measurements of research activity are frequently used, e.g. for evaluating applicants for academic positions. The purpose of this investigation is to assess research activity within the medical speciality of Clinical Biochemistry by comparing it with a matched control group from other medical specialities in Denmark. A list of all physicians registered in Denmark (23,127 persons) was drawn from the database "Laeger.dk". Of these, 5,202 were generalists (not included) while 11,691 were from other specialities. Of the 126 specialists from Clinical Biochemistry, 57 fulfilled the inclusion criteria. Each of these 57 was matched according to medical title with two randomly chosen specialists from other specialities, totaling 114. Using Medline and the Web of Science, the number of publications and the number of citations were then ascertained. 25% of the 11,691 specialists held a PhD degree or doctoral degree, DMSci, (Clinical Biochemistry: 61%). The 171 specialists included in the study had 9,823 papers in Medline and 10,140 papers in the Web of Science. The number of Medline papers per specialist was 71 for Clinical Biochemistry compared to 51 for the control group. The number of citations per specialist was 1,844 for Clinical Biochemistry compared to 816 for the control group. The top ten H-indices (of which 8 were in Clinical Biochemistry) ranged from 30 to 69. Both the number of papers and the number of citations were higher for Clinical Biochemistry than for the control group. The difference was most pronounced among professors.

The fifth Millennium Development Goal formulated by the WHO in 2000 aimed to reduce global maternal mortality by 75% in 2015. We studied the extent to which medical research has supported this by studying maternal mortality. We performed a bibliometric analysis of the literature on maternal mortality and of the development of this literature over time. We searched for publications on maternal mortality in the Web of Science database in the period 1994-2013. We visualised the subjects of these publications using a term map showing the most significant terms occurring in the titles and abstracts of publications on maternal mortality. We identified 3794 publications on maternal mortality in Web of Science. The annual number increased from 87 in 1994 to 397 in 2013. The largest number of maternal mortality publications was found in the field of Obstetrics and Gynecology, followed by the Public, Environmental, and Occupational Health field (increase from 1994 until 2013 of 300% and 700%, respectively). In both fields, the number of maternal mortality publications has increased at a much higher rate than the overall number of publications in the field. In line with the focus of the fifth Millennium Development Goal on reducing maternal mortality, during the past 20 years, there has been a steady increase in the amount of attention paid to maternal mortality in the medical literature. This is largely driven by an increase, mainly in recent years, in public health research on maternal mortality. © 2015 John Wiley & Sons Ltd.

We present GobyWeb, a web-based system that facilitates the management and analysis of high-throughput sequencing (HTS) projects. The software provides integrated support for a broad set of HTS analyses and offers a simple plugin extension mechanism. Analyses currently supported include quantification of gene expression for messenger and small RNA sequencing, estimation of DNA methylation (i.e., reduced bisulfite sequencing and whole genome methyl-seq), or the detection of pathogens in sequenced data. In contrast to previous analysis pipelines developed for analysis of HTS data, GobyWeb requires significantly less storage space, runs analyses efficiently on a parallel grid, scales gracefully to process tens or hundreds of multi-gigabyte samples, yet can be used effectively by researchers who are comfortable using a web browser. We conducted performance evaluations of the software and found it to either outperform or have similar performance to analysis programs developed for specialized analyses of HTS data. We found that most biologists who took a one-hour GobyWeb training session were readily able to analyze RNA-Seq data with state of the art analysis tools. GobyWeb can be obtained at http://gobyweb.campagnelab.org and is freely available for non-commercial use. GobyWeb plugins are distributed in source code and licensed under the open source LGPL3 license to facilitate code inspection, reuse and independent extensions http://github.com/CampagneLaboratory/gobyweb2-plugins.

DMINDA (DNA motif identification and analyses) is an integrated web server for DNA motif identification and analyses, which is accessible at http://csbl.bmb.uga.edu/DMINDA/. This web site is freely available to all users and there is no login requirement. This server provides a suite of cis-regulatory motif analysis functions on DNA sequences, which are important to elucidation of the mechanisms of transcriptional regulation: (i) de novo motif finding for a given set of promoter sequences along with statistical scores for the predicted motifs derived based on information extracted from a control set, (ii) scanning motif instances of a query motif in provided genomic sequences, (iii) motif comparison and clustering of identified motifs, and (iv) co-occurrence analyses of query motifs in given promoter sequences. The server is powered by a backend computer cluster with over 150 computing nodes, and is particularly useful for motif prediction and analyses in prokaryotic genomes. We believe that DMINDA, as a new and comprehensive web server for cis-regulatory motif finding and analyses, will benefit the genomic research community in general and prokaryotic genome researchers in particular.

What Is Bibliometrics and Why Should You Care?

McBurney, Melissa K.; Novak, Pamela L.

When we help an author publish a book or journal article, is that the end of the job? Viewed in the aggregate, a company's publications represent one of its greatest business assets. Can professionals in the information and communication fields help their company understand the return on its investment in publishing? The field of bibliometrics studies publication patterns by using quantitative analysis and statistics. Bibliometrics can be either descriptive, such as looking at how many articles your organization has published, or evaluative, such as using citation analysis to look at how those articles influenced subsequent research by others. Counting publicationsmore » can be useful for doing some comparisons, but citation analysis allows you to look at the impact those articles have had on others by determining how often they are cited. Citation analysis can also show what journals, organizations, and even countries have high impact in different fields of research. The Institute for Scientific Information (ISI) has been a leader in the citation analysis field since 1961, when ISI published the first Science Citation Index. Pacific Northwest National Laboratory has been using data from ISI for both descriptive and evaluative purposes. This data is used to track what the researchers at the Laboratory are writing and then comparing research groups within the organization over a period of years to identify trends and opportunities. PNNL has also used citation analysis to explore what organizations and academic institutions are doing research in certain fields for partnering opportunities. We have realized that the electronic system PNNL uses to approve and track its publications contains very valuable bibliometric data that can be used to make decisions about business directions for the company.« less

Nitazoxanide is a member of a new class of drug, thiazolides, and it was discovered in 1984 with antimicrobial activity effect against anaerobic bacteria, Hepatitis virus, protozoa, and helminths. A bibliometric study on four databases (1984-2016) - Medline, Scopus, LILACS, and SciELO - characterizing the global scientific production of nitazoxanide. We determined the quantity, quality (number of citations), and types of studies developed by each country, characterizing them by years, international cooperation, development, place of publication, authors (with its H-index), and groups with higher impact. There were 512 articles in Medline - the higher scientific production is from the USA (19.71%), Switzerland (7.51%), and Mexico (7.27%). There were 1,440 articles in Scopus - from the USA (8.98%), Mexico (2.13%), and India (1.65%). There were 405 articles in LILACS - from Mexico (4.69%), the USA (4.2%), and Peru (2.47%). There were 47 articles in SciELO - from Brazil (34.04%), Venezuela (21.28%), and Colombia (14.89%). The H-index of nitazoxanide is 75 - the USA (26), Egypt (12), and Canada (10) were the countries contributing more with that. Nitazoxanide research has been highly important. Nevertheless, it is relatively limited when compared with other drugs. Its research has been led by the USA, as revealed in this bibliometric assessment. Although some developing countries, where it is used especially for protozoa and helminths, probably have its influence, and this explains the fact that Mexico and India, among others, are the top countries in the scientific production of this anti-infective agent. This bibliometric study evidenced a relatively low number of publications, however, it has been increased in recent years.

Publications are an important tool to measure one's success and achievement in academia. They can help propel a career forward and move one into a position of leadership. The overall purpose of this study was to investigate changes in bibliometric variables, authorship, and collaboration trends in the Journal of Orthopaedic Research (JOR®), since its inception in 1983. A bibliometric analysis was completed for all manuscripts meeting the inclusion criteria (638), which were published throughout the inaugural year plus one representative year of each decade. Several parameters were investigated including numbers of manuscripts, authors, collaborating institutions/countries, references, pages, and citations; region of origin and gender of authors over time and by region were main focuses. Significant increases over time were observed in all bibliometric variables analyzed except in the number of pages and citations. There was an approximate 27% point increase for both female first and corresponding authors from 1983 to 2015. While this is most likely due to the increase in the number of women that have entered the field over time, similar increases in the percentage of women holding positions on the JOR editorial board or in leadership positions within in the field may have also contributed to improvements in gender parity. Understanding changes in publishing characteristics over time, by region, and by gender are critical, especially with the rising demands of publishing in academia. JOR has seen increase in most variables analyzed, including improvements in authorship by women in the field of orthopaedic research. © 2018 Orthopaedic Research Society.

Does bibliometric research confer legitimacy to research assessment practice? A sociological study of reputational control, 1972-2016

PubMed Central

Jappe, Arlette; Pithan, David

2018-01-01

The use of bibliometric measures in the evaluation of research has increased considerably based on expertise from the growing research field of evaluative citation analysis (ECA). However, mounting criticism of such metrics suggests that the professionalization of bibliometric expertise remains contested. This paper investigates why impact metrics, such as the journal impact factor and the h-index, proliferate even though their legitimacy as a means of professional research assessment is questioned. Our analysis is informed by two relevant sociological theories: Andrew Abbott’s theory of professions and Richard Whitley’s theory of scientific work. These complementary concepts are connected in order to demonstrate that ECA has failed so far to provide scientific authority for professional research assessment. This argument is based on an empirical investigation of the extent of reputational control in the relevant research area. Using three measures of reputational control that are computed from longitudinal inter-organizational networks in ECA (1972–2016), we show that peripheral and isolated actors contribute the same number of novel bibliometric indicators as central actors. In addition, the share of newcomers to the academic sector has remained high. These findings demonstrate that recent methodological debates in ECA have not been accompanied by the formation of an intellectual field in the sociological sense of a reputational organization. Therefore, we conclude that a growing gap exists between an academic sector with little capacity for collective action and increasing demand for routine performance assessment by research organizations and funding agencies. This gap has been filled by database providers. By selecting and distributing research metrics, these commercial providers have gained a powerful role in defining de-facto standards of research excellence without being challenged by expert authority.

We aimed to identify and analyze the characteristics of the 100 most highly-cited papers in the research field of deep brain stimulation (DBS). The Web of Science was searched for highly-cited papers related to DBS research. The number of citations, countries, institutions of origin, year of publication, and research area were noted and analyzed. The 100 most highly-cited articles had a mean of 304.15 citations. These accrued an average of 25.39 citations a year. The most represented target by far was the subthalamic nucleus (STN). These articles were published in 46 high-impact journals, with Brain (n = 10) topping the list. These articles came from 11 countries, with the USA contributing the most highly-cited articles (n = 29); however, it was the University of Toronto (n = 13) in Canada that was the institution with the most highly-cited studies. This study identified the 100 most highly-cited studies and highlighted a historical perspective on the progress in the field of DBS. These findings allow for the recognition of the most influential reports and provide useful information that can indicate areas requiring further investigation.

An analysis of scientific bibliographic productivity using the Hirsch h-index, information from the Institute of Scientific Information database and the Curriculum Lattes (CNPq, Brazil) was performed at the Faculdade de Filosofia, Ciências e Letras de Ribeirão Preto, Universidade de São Paulo (FFCLRP-USP) that has four departments in natural, biological and social sciences. Bibliometric evaluations of undergraduate programs showed a better performance of the departments of Chemistry (P < 0.001) and Biology (P < 0.001) when compared to the departments of Physics and Mathematics and Psychology and Education. We also analyzed the scientific output of the six graduate programs of FFCLRP: Psychology, Psychobiology, Chemistry, Physics Applied to Medicine and Biology, Comparative Biology, and Entomology. The graduate program in Psychology presented a lower h-index (P < 0.001) and had fewer papers indexed by the ISI web of science (P < 0.001) when compared to the other graduate programs. The poorer performance of the Psychology program may be associated with the limited coverage by the Thompson Institute of Scientific Information database.

This article aims to understand the global and longitudinal trends of research on Panax ginseng . We used bibliometrics to analyze 3974 papers collected from the Web of Science TM Core Collection database during 1959-2016. The number of publications showed a steady growth before 2000 and exponentially increased in stage III (2000-2016, about 86% of the papers were published). Research on P. ginseng was conducted in 64 countries, mainly in Asia; in particular, 41% and 28% of the publications were from South Korea and China, respectively. The institutions from South Korea and China had high publication output and close cooperation and provided the majority of financial support. All top 10 authors and four of the top 20 journals in terms of number of publications originated from South Korea. The leading research subjects were pharmacology (39%), plant science (26%), and integrative complementary medicine (19%). The hotspot of P. ginseng research transformed from basic science to application, and multidisciplinary sciences will play a substantial role in the future. This study provides a comprehensive analysis to elucidate the global distribution, collaboration patterns, and research trends in the P. ginseng domain.

In this study, university-industry collaborations in China and the USA are analyzed in terms of co-authored publications indexed in the Web of Science (WoS). Results show a wide gap between China and the USA: Chinese universities are much less active in collaborations with industry in terms of either publication productivity or collaboration intensity. In selecting local and foreign industrial partners, however, more variation exists among Chinese universities than among US universities. The US system is domestically oriented more than that of China. In the USA, the intensity of university-industry collaboration is determined by research quality, whereas in China this is not the case. In both China and the USA, distance is not critical for the establishment of domestic university-industry collaboration. A high correlation is found between productivity indicators including total publications and university-industry co-authored publications. However, the productivity indicators are less correlated with the intensity of university-industry collaboration. Large research universities with strong ties to domestic industry play critical roles in both national publication systems.

2017-01-01

Introduction The 2014/2015 West African Ebola Virus Disease (EVD) outbreak attracted global attention. Numerous opinions claimed that the global response was impaired, in part because, the EVD research was neglected, although quantitative or qualitative studies did not exist. Our objective was to analyse how the EVD research landscape evolved by exploring the existing research network and its communities before and during the outbreak in West Africa. Methods/ Principal findings Social network analysis (SNA) was used to analyse collaborations between institutions named by co-authors as affiliations in publications on EVD. Bibliometric data of publications on EVD between 1976 and 2015 was collected from Thomson Reuters’ Web of Science Core Collection (WoS). Freely available software was used for network analysis at a global-level and for 10-year periods. The networks are presented as undirected-weighted graphs. Rankings by degree and betweenness were calculated to identify central and powerful network positions; modularity function was used to identify research communities. Overall 4,587 publications were identified, of which 2,528 were original research articles. Those yielded 1,644 authors’ affiliated institutions and 9,907 connections for co-authorship network construction. The majority of institutions were from the USA, Canada and Europe. Collaborations with research partners on the African continent did exist, but less frequently. Around six highly connected organisations in the network were identified with powerful and broker positions. Network characteristics varied widely among the 10-year periods and evolved from 30 to 1,489 institutions and 60 to 9,176 connections respectively. Most influential actors are from public or governmental institutions whereas private sector actors, in particular the pharmaceutical industry, are largely absent. Conclusion/ Significance Research output on EVD has increased over time and surged during the 2014/2015 outbreak. The overall EVD research network is organised around a few key actors, signalling a concentration of expertise but leaving room for increased cooperation with other institutions especially from affected countries. Finding innovative ways to maintain support for these pivotal actors while steering the global EVD research network towards an agenda driven by agreed, prioritized needs and finding ways to better integrate currently peripheral and newer expertise may accelerate the translation of research into the development of necessary live saving products for EVD ahead of the next outbreak.

The 2014/2015 West African Ebola Virus Disease (EVD) outbreak attracted global attention. Numerous opinions claimed that the global response was impaired, in part because, the EVD research was neglected, although quantitative or qualitative studies did not exist. Our objective was to analyse how the EVD research landscape evolved by exploring the existing research network and its communities before and during the outbreak in West Africa. Social network analysis (SNA) was used to analyse collaborations between institutions named by co-authors as affiliations in publications on EVD. Bibliometric data of publications on EVD between 1976 and 2015 was collected from Thomson Reuters' Web of Science Core Collection (WoS). Freely available software was used for network analysis at a global-level and for 10-year periods. The networks are presented as undirected-weighted graphs.

Epidemiology and the reporting characteristics of systematic reviews (SRs) and meta-analyses (MAs) are well known. However, no study has analyzed the influence of protocol features on the probability that a study's results will be finally reported, thereby indirectly assessing the reporting bias of International Prospective Register of Systematic Reviews (PROSPERO) registration records. The objective of this study is to explore which factors are associated with a higher probability that results derived from a non-Cochrane PROSPERO registration record for a systematic review will be finally reported as an original article in a scientific journal. The PROSPERO repository will be web scraped to automatically and iteratively obtain all completed non-Cochrane registration records stored from February 2011 to December 2017. Downloaded records will be screened, and those with less than 90% fulfilled or are duplicated (i.e., those sharing titles and reviewers) will be excluded. Manual and human-supervised automatic methods will be used for data extraction, depending on the data source (fields of PROSPERO registration records, bibliometric databases, etc.). Records will be classified into published, discontinued, and abandoned review subgroups. All articles derived from published reviews will be obtained through multiple parallel searches using the full protocol "title" and/or "list reviewers" in MEDLINE/PubMed databases and Google Scholar. Reviewer, author, article, and journal metadata will be obtained using different sources. R and Python programming and analysis languages will be used to describe the datasets; perform text mining, machine learning, and deep learning analyses; and visualize the data. We will report the study according to the recommendations for meta-epidemiological studies adapted from the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement for SRs and MAs. This meta-epidemiological study will explore, for the first time, characteristics of PROSPERO records that may be associated with the publication of a completed systematic review. The evidence may help to improve review workflow performance in terms of research topic selection, decision-making regarding team selection, planning relationships with funding sources, implementing literature search strategies, and efficient data extraction and analysis. We expect to make our results, datasets, and R and Python code scripts publicly available during the third quarter of 2018.

Influenza virus vaccine (IVV) is a promising research domain that is closely related to global health matters, which has been acknowledged not only by scientists and technology developers, but also by policy-makers. Meanwhile, patents encompass valuable technological information and reflect the latest technological inventions as well as the innovative capability of a nation. However, little research has examined this up-and-coming research field using patent bibliometric method. Thus, this paper (a) designs the technology classification system and search strategy for the identification of IVV; and (b) presents a longitudinal analysis of the global IVV development based on the European Patent Office (EPO) patents. Bibliometric analysis is used to rank countries, institutions, inventors and technology subfields contributing to IVV technical progress. The results show that the global trends of IVV are a multi-developing feature of variety but an uneven technical resource distribution. Although the synthetic peptide vaccine is a comparatively young field, it already demonstrates the powerful vitality and the enormous development space. With the worldwide competition increasing, all nations especially China should be looking to increase devotion, enhance capability and regard effectiveness of technological innovation.

Imbalances in female career promotion are believed to be strong in the field of academic science. A primary parameter to analyze gender inequalities is the gender authoring in scientific publications. Since the presently available data on gender distribution is largely limited to underpowered studies, we here develop a new approach to analyze authors' genders in large bibliometric databases. A SQL-Server based multiuser software suite was developed that serves as an integrative tool for analyzing bibliometric data with a special emphasis on gender and topographical analysis. The presented system allows seamless integration, inspection, modification, evaluation and visualization of bibliometric data. By providing an adaptive and almost fully automatic integration and analysis process, the inter-individual variability of analysis is kept at a low level. Depending on the scientific question, the system enables the user to perform a scientometric analysis including its visualization within a short period of time. In summary, a new software suite for analyzing gender representations in scientific articles was established. The system is suitable for the comparative analysis of scientific structures on the level of continents, countries, cities, city regions, institutions, research fields and journals.

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

To identify global research trends of follicle and melanocyte stem cells, and their application in neuroscience. We performed a bibliometric analysis of studies from 2002 to 2011 on follicle and melanocyte stem cells, and their application in neuroscience, which were retrieved from the Web of Science, using the key words follicle stem cell or melanocyte stem cell, and neural, neuro or nerve. (a) peer-reviewed published articles on follicle and melanocyte stem cells, and their application in neuroscience, which were indexed in the Web of Science; (b) original research articles, reviews, meeting abstracts, proceedings papers, book chapters, editorial material, and news items. (a) articles that required manual searching or telephone access; (b) documents that were not published in the public domain; and (c) a number of corrected papers from the total number of articles. (1) Distribution of publications on follicle and melanocyte stem cells by years, journals, countries, institutions, institutions in China, and most cited papers. (2) Distribution of publications on the application of follicle and melanocyte stem cells in neuroscience by years, journals, countries, institutions, and most cited papers. Of the 348 publications from 2002 to 2011 on follicle and melanocyte stem cells, which were retrieved from the Web of Science, more than half were from American authors and institutes. The most prolific institutions in China for publication of papers on follicle and melanocyte stem cells were the Fourth Military Medical University and Third Military Medical University. The most prolific journals for publication of papers on follicle and melanocyte stem cells were the Journal of Investigative Dermatology, Pigment Cell & Melanoma Research. Of the 63 publications from 2002 to 2011 on the application of follicle and melanocyte stem cells in neuroscience, which were retrieved from the Web of Science, more than half were from American authors and institutes, and no papers were from Chinese authors and institutes. The most prolific journals for publication of papers on the application of follicle and melanocyte stem cells in neuroscience were the Journal of Investigative Dermatology, Pigment Cell & Melanoma Research. Based on our analysis of the literature and research trends, we found that follicle stem cells might offer further benefits in neural regenerative medicine.

To identify global research trends in three therapies for children with cerebral palsy. We performed a bibliometric analysis of studies on therapies for children with cerebral palsy from 2002 to 2011 retrieved from Web of Science. (a) peer-reviewed published articles on botulinum toxin, constraint-induced movement therapy, or acupuncture for children with cerebral palsy indexed in Web of Science; (b) original research articles, reviews, meeting abstracts, proceedings papers, book chapters, editorial material, and news items; and (c) publication between 2002 and 2011. (a) articles that required manual searching or telephone access; (b) documents that were not published in the public domain; and (c) a number of corrected papers from the total number of articles. (1) Number of publications on the three therapies; (2) annual publication output, distribution by journals, distribution by institution, and top-cited articles on botulinum toxin; (3) annual publication output, distribution by journal, distribution by institution, and top-cited articles on constraint-induced movement therapy; (4) annual publication, distribution by journal, distribution by institution, and top-cited articles on acupuncture. This analysis, based on Web of Science articles, identified several research trends in studies published over the past 10 years of three therapies for children with cerebral palsy. More articles on botulinum toxin for treating children with cerebral palsy were published than the articles regarding constraint-induced movement therapy or acupuncture. The numbers of publications increased over the 10-year study period. Most papers appeared in journals with a focus on neurology, such as Developmental Medicine and Child Neurology and Journal of Child Neurology. Research institutes publishing on botulinum toxin treatments for this population are mostly in the Netherlands, the United States of America, and Australia; those publishing on constraint-induced movement therapy are mostly in Australia and the United States of America; and those publishing on acupuncture are mostly in China, Sweden and the United States of America. Analysis of literature and research trends indicated that there was no one specific therapy to cure cerebral palsy. Further studies are still necessary.

Aspirin resistance can be defined as the inability of the usual dose of aspirin medication to produce its antithrombotic effect. Patients with diabetes or cardiovascular disease are at higher risk of stroke, myocardial infarction or cardiovascular death due to aspirin resistance. The aim of this bibliometric study was to identify and analyse the status and trends of aspirin resistance research production at global level through publications indexed in the Scopus database; this will shed new light on future research trends and help researchers predict dynamic direction of research. Literature search using the Scopus database was conducted to assess publications related to aspirin resistance. The selected publications included the terms related to aspirin resistance in the title, abstract or keywords. The searching was accomplished on 20 March 2016 and can be considered to include all publications up to 31 December 2015. Global cumulative publication output on aspirin resistance consists of 986 papers during 1990-2015. Among the 986 documents, 19 (1.9%) were published before 2000, 567 (57.5%) were published from 2000 to 2009 and 400 (40.6%) were published from 2010 to 2015, with peak of publications on this topic in 2008. The leading country in the field of aspirin resistance was the United States, which had the greatest counts of independent articles (165) and international collaboration articles (44). Turkey was in the second rank with 78 articles, followed by Italy (68), the UK (62) and Poland (60). The total number of citations for all documents was 26,342, and the average citations per document were 26.7. The h-index for all aspirin resistance publications was 82. This study presents the results of the first bibliometric study (including quantitative and qualitative analysis) of scientific publications in the field of aspirin renitence at global level. Aspirin resistance-related researches have notably increased in the last years, especially from 2000 to 2015. The United States is the most prolific country, not only in research quantity but also in quality. Furthermore, Turkey and European countries provided more research related to aspirin resistance than other regions such as the developing countries. © 2017 Nordic Association for the Publication of BCPT (former Nordic Pharmacological Society).

Mapping Publication Trends and Identifying Hot Spots of Research on Internet Health Information Seeking Behavior: A Quantitative and Co-Word Biclustering Analysis

Background The Internet has become an established source of health information for people seeking health information. In recent years, research on the health information seeking behavior of Internet users has become an increasingly important scholarly focus. However, there have been no long-term bibliometric studies to date on Internet health information seeking behavior. Objective The purpose of this study was to map publication trends and explore research hot spots of Internet health information seeking behavior. Methods A bibliometric analysis based on PubMed was conducted to investigate the publication trends of research on Internet health information seeking behavior. For the included publications, the annual publication number, the distribution of countries, authors, languages, journals, and annual distribution of highly frequent major MeSH (Medical Subject Headings) terms were determined. Furthermore, co-word biclustering analysis of highly frequent major MeSH terms was utilized to detect the hot spots in this field. Results A total of 533 publications were included. The research output was gradually increasing. There were five authors who published four or more articles individually. A total of 271 included publications (50.8%) were written by authors from the United States, and 516 of the 533 articles (96.8%) were published in English. The eight most active journals published 34.1% (182/533) of the publications on this topic. Ten research hot spots were found: (1) behavior of Internet health information seeking about HIV infection or sexually transmitted diseases, (2) Internet health information seeking behavior of students, (3) behavior of Internet health information seeking via mobile phone and its apps, (4) physicians’ utilization of Internet medical resources, (5) utilization of social media by parents, (6) Internet health information seeking behavior of patients with cancer (mainly breast cancer), (7) trust in or satisfaction with Web-based health information by consumers, (8) interaction between Internet utilization and physician-patient communication or relationship, (9) preference and computer literacy of people using search engines or other Web-based systems, and (10) attitude of people (especially adolescents) when seeking health information via the Internet. Conclusions The 10 major research hot spots could provide some hints for researchers when launching new projects. The output of research on Internet health information seeking behavior is gradually increasing. Compared to the United States, the relatively small number of publications indexed by PubMed from other developed and developing countries indicates to some extent that the field might be still underdeveloped in many countries. More studies on Internet health information seeking behavior could give some references for health information providers. PMID:25830358

To identify whether regional differences exist in gender disparities in scholarly productivity and faculty rank among academic otolaryngologists. Academic otolaryngologists' bibliometric data analyses. Online faculty listings from 98 otolaryngology departments were organized by gender, academic rank, fellowship training status, and institutional location. The Scopus database was used to assess bibliometrics of these otolaryngologists, including the h-index, number of publications, and publication experience. Analysis included 1127 otolaryngologists, 916 men (81.3%) and 211 women (18.7%). Female faculty comprised 15.4% in the Midwest, 18.8% in the Northeast, 21.3% in the South, and 19.0% in the West (P = .44). Overall, men obtained significantly higher senior academic ranks (associate professor or professor) compared to women (59.8% vs. 40.2%, P < .0001). Regional gender differences in senior faculty were found in the South (59.8% men vs. 37.3% women, P = .0003) and Northeast (56.4% men vs. 24.1% women, P < .0001) with concomitant gender differences in scholarly impact, as measured by the h-index (South, P = .0003; Northeast, P = .0001). Among geographic subdivisions, female representation at senior ranks was lowest in the Mid-Atlantic (22.0%), New England (30.8%), and West South Central (33.3%), while highest in Pacific (60.0%) and Mountain (71.4%) regions. No regional gender differences were found in fellowship training patterns (P-values > .05). Gender disparities in academic rank and scholarly productivity exist most notably in the Northeast, where women in otolaryngology are most underrepresented relative to men at senior academic ranks and in scholarly productivity.

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

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

DMINDA (DNA motif identification and analyses) is an integrated web server for DNA motif identification and analyses, which is accessible at http://csbl.bmb.uga.edu/DMINDA/. This web site is freely available to all users and there is no login requirement. This server provides a suite of cis-regulatory motif analysis functions on DNA sequences, which are important to elucidation of the mechanisms of transcriptional regulation: (i) de novo motif finding for a given set of promoter sequences along with statistical scores for the predicted motifs derived based on information extracted from a control set, (ii) scanning motif instances of a query motif in provided genomic sequences, (iii) motif comparison and clustering of identified motifs, and (iv) co-occurrence analyses of query motifs in given promoter sequences. The server is powered by a backend computer cluster with over 150 computing nodes, and is particularly useful for motif prediction and analyses in prokaryotic genomes. We believe that DMINDA, as a new and comprehensive web server for cis-regulatory motif finding and analyses, will benefit the genomic research community in general and prokaryotic genome researchers in particular. © The Author(s) 2014.

The aim of the study was to analyze the 100 most cited publications with Turkish origin in the Web of Science Otorhinolaryngology (ORL) journals. The Web of Science database was searched in terms of citations for publications originating from Turkey in ORL journals since 1983. After the identification of the 100 most cited articles, analysis was performed for the first author, institution, city, publication type, subject related to subspecialty, and journals having the most cited articles. Moreover, the number of ORL publications and citations of countries was determined in descending order using the same database. A total of 3948 ORL articles with Turkish origin was identified. The number of citations was 181 for the first and 28 for the last in the 100 most cited articles. As there was more than one article with 28 citations, 101 articles were analyzed. The number of the articles was 76, 22, and 3 for the university, education/research, and state hospitals, respectively. Hacettepe University, Ankara Numune Hospital, and Gazi University were the three leading institutions having the most cited articles, and Ankara was the first city. While 98 of 101 articles were original research, the number of case reports and review articles were 2 and 1, respectively. Thirty-five articles were related to otology, 23 to pediatric ORL, 20 to rhinology and head and neck surgery, and 3 to facial plastic surgery. Laryngoscope, Otolaryngology-Head and Neck Surgery, and International Journal of Pediatric Otorhinolaryngology were the leading 3 journals with the most cited articles coming from Turkey. The evaluation of countries revealed that Turkey was among the first 10 countries in terms of number of ORL articles but fell behind for the number of citations. This bibliometric study is the first one regarding the contribution of Turkish authors and institutions to ORL literature. Similar studies might be periodically repeated to determine national development in the field of ORL and place of Turkey in the world.

Bibliometrics for Social Validation.

PubMed

Hicks, Daniel J

2016-01-01

This paper introduces a bibliometric, citation network-based method for assessing the social validation of novel research, and applies this method to the development of high-throughput toxicology research at the US Environmental Protection Agency. Social validation refers to the acceptance of novel research methods by a relevant scientific community; it is formally independent of the technical validation of methods, and is frequently studied in history, philosophy, and social studies of science using qualitative methods. The quantitative methods introduced here find that high-throughput toxicology methods are spread throughout a large and well-connected research community, which suggests high social validation. Further assessment of social validation involving mixed qualitative and quantitative methods are discussed in the conclusion.

Background: The field of child and adolescent psychiatry lags behind adult psychiatry significantly. In recent years, it has witnessed a significant increase in the publication of journals and articles. This study provides a detailed bibliometric analysis of articles published from 1980 to 2016, in the top seven journals of child and adolescent psychiatry. Methods: Using the Web of Science core collection, we selected 9,719 research papers published in seven psychiatric journals from 1980 to 2016. We utilized the Web of Science Analytics tool and Network Analysis Interface for Literature Studies (NAILS) Project scripts to delineate the general trends of publication in these journals. Then, co-citation analysis and hierarchical cluster analysis was performed using CiteSpace to map important papers, landmark theories and foci of research in child and adolescent psychiatry. Results: The field of child and adolescent psychiatry has experienced an increasing trend in research, which was reflected in the results of this study. Hierarchical cluster analysis revealed that the research foci in psychiatry were primarily studies related to the design of psychometric instruments, checklists, taxonomy, attention deficit hyperactivity disorder (ADHD), depression, PTSD, social phobia, and psychopharmacology. Moreover, several landmark studies, including the validation of a child behavior checklist, Ainsworth's empirical evidence of Bowlby's attachment theory, and adult outcomes of childhood dysregulation were published. This study also reports rapid expansion and innovation in research areas in the field of child and adolescent psychiatry from 1980-2016. Conclusions: Rapid expansion and innovation in research areas in the field of child and adolescent psychiatry has been observed, from 1980 to 2016. PMID:28944045

This paper shows how the Rao-Stirling diversity index may be extensively used for positioning and comparing institutions interdisciplinary practices. Two decompositions of this index make it possible to explore different components of the diversity of the cited references in a corpus of publications. The paper aims at demonstrating how these bibliometric tools can be used for comparing institutions in a research field by highlighting collaboration orientations and institutions strategies. To make the method available and easy to use for indicator users, this paper first recalls a previous result on the decomposition of the Rao-Stirling index into multidisciplinarity and interdisciplinarity components, then proposes a new decomposition to further explore the profile of research collaborations and finally presents an application to Neuroscience research in French universities.

Background: It might be difficult for clinicians and scientists to identify comprehensively the major research topics given the large number of publications. A bibliometric report that identifies the most-cited articles within the body of the relevant literature may provide insight and guidance for readers toward scientific topics that are considered important for researchers and all relevant workers of academia. To our knowledge, there is a lack of an overall evaluation of the most-cited articles and hence of a comprehensive review of major research topics in neuroscience. The present study was therefore proposed to analyze and characterize the 100 most-cited articles in neuroscience. Methods: Based on data provided from Web of Science, the 100 most-cited articles relevant to neuroscience were identified and characterized. Information was extracted for each included article to assess for the publication year, journal published, impact factor, adjusted impact factor, citation count (total, normalized, and adjusted), reference list, authorship and article type. Results: The total citation count for the 100 most-cited articles ranged from 7,326 to 2,138 (mean 3087.0) and the normalized citation count ranged from 0.163 to 0.007 (mean 0.054). The majority of the 100 articles were research articles (67%) and published from 1996 to 2000 (30%). The author and journal with the largest share of these 100 articles were Stephen M. Smith (n = 6) and Science (n = 13) respectively. Among the 100 most-cited articles, 37 were interlinked via citations of one another, and they could be classified into five major topics, four of which were scientific topics, namely neurological disorders, prefrontal cortex/emotion/reward, brain network, and brain mapping. The remaining topic was methodology. Interestingly 41 out of 63 of the rest, non-interlinked articles could also be categorized under the above five topics. Adjusted journal impact factor among these 100 articles did not appear to be associated with the corresponding adjusted citation count. Conclusion: The current study compiles a comprehensive list and analysis of the 100 most-cited articles relevant to neuroscience that enables the comprehensive identification and recognition of the most important and relevant research topics concerned.

Bibliometric analysis is increasingly employed as a useful tool to assess the quantity and quality of research performance. The specific goal of the current study was to evaluate the performance of research output originating from Arab world and published in international Integrative and Complementary Medicine (ICM) journals. Original scientific publications and reviews from the 22 Arab countries that were published in 22 international peer-reviewed ICM journals during all previous years up to December 31(st) 2013, were screened using the Web of Science databases. Five hundred and ninety-one documents were retrieved from 19 ICM journals. The h-index of the set of papers under study was 47. The highest h-index was 27 for Morocco, 21 for Jordan, followed by 19 for each Kingdom of Saudi Arabia (KSA), and Egypt, and the lowest h-index was 1 for each of Comoros, Qatar, and Syrian Arab Republic. No data related to ICM were published from Djibouti, and Mauritania. After adjusting for economy and population power, Somalia (89), Morocco (32.5), Egypt (31.1), Yemen (21.4), and Palestine (21.2) had the highest research productivity. The total number of citations was 9,466, with an average citation of 16 per document. The study identified 262 (44.3 %) documents with 39 countries in Arab-foreign country collaborations. Arab authors collaborated most with countries in Europe (24.2 %), followed by countries in the Asia-Pacific region (9.8 %). Scientific research output in the ICM field in the Arab world region is increasing. Most of publications from Arab world in ICM filed were driven by societal use of medicinal plants and herbs. Search for new therapies from available low cost medicinal plants in Arab world has motivated many researchers in academia and pharmaceutical industry. Further investigation is required to support these findings in a wider journal as well as to improve research output in the field of ICM from Arab world region by investing in more national and international collaborative research project.

The objectives of this bibliometric analysis of the scientific literature were to describe the research subjects and the international collaborations in the field of research on infectious diseases in livestock animals including fishes and honeybees. It was based on articles published worldwide from 2006 through 2013. The source of data was the Web of Science, Core collection(®) and only papers fully written in English were considered. Queries were built that combined 130 descriptors related to animal species and 1213 descriptors related to diseases and pathogens. To refine and assess the accuracy of the extracted database, supplementary filters were applied to discard non-specific terms and neighbouring topics, and numerous tests were carried out on samples. For pathogens, annotation was done using a thematic terminology established to link each disease with its corresponding pathogen, which was in turn classified according to its family. A total of 62,754 articles were published in this field during this 8-year period. The average annual growth rate of the number of papers was 5%. This represents the reference data to which we compared the average annual growth rate of articles produced in each of the sub-categories that we defined. Thirty-seven percent of the papers were dedicated to ruminant diseases. Poultry, pigs and fishes were covered by respectively 21, 13 and 14% of the total. Thirty-seven percent of papers concerned bacteria, 33% viruses, 19% parasites, 2% prions, the remaining being multi-pathogens. Research on virology, especially on pigs and poultry, is increasing faster than the average. There also is increasing interest in monogastric species, fish and bees. The average annual growth rate for Asia was 10%, which is high compared to 3% for Europe and 2% for the Americas, indicating that Asia is currently playing a leading role in this field. There is a well established network of international collaborations. For 75% of the papers, the co-authors were from the same country, for 10%, they were from different countries on the same continent, and for 15%, they were from different continents. The annual growth rate of papers representing international collaborations generally is increasing more quickly than the overall average.

This study aimed to evaluate the quantity and quality of articles from different countries involving arthroscopy to investigate the characteristics of worldwide research productivity. Web of Science was searched for arthroscopy articles published between 1999 and 2013. The numbers of articles and citations were analyzed to assess the contributions of different countries. Publication activity was adjusted by country population and gross domestic product (GDP). A total of 12,553 articles were published worldwide. The time trend for the number of articles showed an increase of 2.27-fold between 1999 and 2013. North America, Western Europe, and Eastern Asia were the most productive areas. High-income countries published 90.86% of the articles; middle-income countries, 9.11%; and lower-income countries, only 0.02%. The United States published the most articles (35.40%), followed by Germany (9.53%), the United Kingdom (6.80%), the Republic of Korea (5.45%), and Japan (4.76%), and had the highest total citations (78,161). However, Sweden had the highest mean citations (35.56), followed by Switzerland (23.39) and the Netherlands (18.90). There were positive correlations between the number of publications and population/GDP (P < .01). When normalized to population, Switzerland ranked the highest, followed by Finland and Sweden. When adjusted by GDP, the Republic of Korea ranked first, followed by Finland and Turkey. The number of publications on arthroscopy increased significantly from 1999 to 2013, with a more than 2-fold increase in volume. The United States was the most productive country as measured by total publications, but when adjusted for population, Switzerland published the highest number of articles, followed by Finland and Sweden. When publications were adjusted for GDP, the Republic of Korea ranked first, with Finland second and Turkey third. Bibliometric analysis allows us to understand contributions of different world regions in scientific research in the field of arthroscopy and gives insight into the quantity and quality of articles related to arthroscopy.

Measuring the Value of Research Data: A Citation Analysis of Oceanographic Data Sets

PubMed Central

Belter, Christopher W.

2014-01-01

Evaluation of scientific research is becoming increasingly reliant on publication-based bibliometric indicators, which may result in the devaluation of other scientific activities - such as data curation – that do not necessarily result in the production of scientific publications. This issue may undermine the movement to openly share and cite data sets in scientific publications because researchers are unlikely to devote the effort necessary to curate their research data if they are unlikely to receive credit for doing so. This analysis attempts to demonstrate the bibliometric impact of properly curated and openly accessible data sets by attempting to generate citation counts for three data sets archived at the National Oceanographic Data Center. My findings suggest that all three data sets are highly cited, with estimated citation counts in most cases higher than 99% of all the journal articles published in Oceanography during the same years. I also find that methods of citing and referring to these data sets in scientific publications are highly inconsistent, despite the fact that a formal citation format is suggested for each data set. These findings have important implications for developing a data citation format, encouraging researchers to properly curate their research data, and evaluating the bibliometric impact of individuals and institutions.

Journals are currently assessed and ranked using a number of different quantitative performance metrics. To compare and correlate the publication metrics of English-language occupational therapy journals published in 2015. Bibliometric data was sourced for 14 English-language occupational therapy journals including the Journal Citations Report (JCR) 2-year impact factor (IF), Eigenfactor Score (EFS), Article Influence Score (AIS), Scopus Source Normalized Impact per Paper (SNIP), Scopus Citescore, and SCImago Journal Rank (SJR) score. The JCR, Scopus, and SJR 2015 bibliometric data were correlated. The top six English-language occupational therapy journals in relation to JCR IF, EFS, AIS, SNIP, Citescore, SJR score, and SJR IIF were AJOT, AOTJ, POPT, CJOT, SJOT, and BJOT. JCR IF, EFS, JCR AIS, SNIP, Citescore, SJR score and SJR IIF were all significantly correlated with coefficients ranging from 0.751 to 0.961 (p < 0.05; p < 0.01). The calculated SJR IIF was on average 0.335 larger than the JCR IFs reported. The findings indicate that the range of available bibliometric measures should be used collectively to yield a more comprehensive assessment of journal and article rankings rather than the singular use of IF scores that currently and frequently occurs in many jurisdictions.

The quality and quantity of published research papers are important in both scientific and technology fields. Although there are several bibliometric studies based on citation analysis, very few have focused on research related to Traditional Chinese Medicine in China. The bibliometric method used in this study included the following focuses: publication outputs for each year, paper type, language of publication, distribution of internationally collaborative countries, sources of funding, authorization number, distribution of institutes regarding collaborative publications, research fields, distribution of outputs in journals, citation, data, and h-index. A total of 3809 papers published from 1995 to 2012 were extracted from the science citation index (SCI). The cumulative number of papers from all six universities is constantly increasing. The United States attained the dominant position regarding complementary and alternative medicine research. The Chinese Academy of Sciences was the greatest participator in collaborative efforts. Research field analysis showed that the research mainly focused on pharmacology pharmacy, chemistry, integrative complementary medicine, plant sciences, and biochemistry molecular biology. The Shanghai University of Chinese Medicine had the most citations. In recent years, in terms of SCI papers, the six Traditional Chinese Medicine universities studied here have made great advances in scientific research.

The monosialoganglioside (GM1) is a popular topic of research but the bibliometric analysis of GM1 over the decades in Science Citation Index-Expanded (SCI-E) remains poorly understood. To identify the global research and to improve the understanding of research trends in the GM1 field from 1942 to 2011. A bibliometric study. We performed a bibliometric analysis based on the SCI-E published by the Institute of Scientific Information. Articles closely related to GM1 were included. Exclusive criteria: (1) Articles related to gangliosidosis, disialo-ganglioside, trisialo-ganglioside or ganglioside GQIb. (2) Document types such as meeting abstracts, reviews, proceedings papers, notes, and letters. (1) Type of publication output; (2) number of author outputs; (3) distribution of output in subject categories; (4) publication distribution of countries; (5) distribution of output in journals, and (6) distribution of citations in each decade. During 1942 to 2011, there were 10 126 papers on GM1 that were added to the SCI. Articles (8 004) were the most frequently used document type comprising 79.0%, followed by meeting abstracts, reviews and proceedings papers. Research on GM1 could be found in the SCI from 1942, it was developed in the 1970s, greatly increased in the 1980s, and reached a peak in the 1990s, and it was slightly decreased in 2000. The distribution of subject categories showed that GM1 research covered both clinical and basic science research. The USA, Japan, and Germany were the three most productive countries, and the publication numbers in the USA were highest in all decades. The Journal of Biological Chemistry, Journal of Neurochemistry and Biochemistry were core subject journals in GM1 studies in each decade. This study highlights the topics in GM1 research that are being published around the world.

HOW TO EVALUATE SCIENTIFIC PRODUCTION.

PubMed

Antunes, Alberto Azoubel

2015-01-01

To conduct a critical analysis of the two main bibliometric indexes used by science: the impact factor and the H index. Research was conducted on PubMed using the keywords: impact factor, Bibliometrics and H index. The citations of articles tend to follow a curve in which the articles published in a given year increase sharply to a peak occurring between two and six years after its publication. From this peak citations decline over time. The analysis of the scientific merit should not be based on only in bibliometric measure, but in the association of various parameters. The impact factor and the H index is mainly based on the number of citations of scientific papers, and this parameter, although important, should not be used alone, nor overvalued in the evaluation of teaching merit. Realizar análise crítica dos dois principais índices bibliométricos utilizados pela ciência: o fator de impacto e o índice H. Foi realizada pesquisa no Pubmed utilizando as palavras-chave: impact factor, bibliometrics, H index. As citações dos artigos tendem a seguir uma curva em que os artigos publicados em determinado ano aumentam agudamente para um pico que ocorre entre dois e seis anos após sua publicação. A partir deste pico, as citações declinam ao longo do tempo. A análise do mérito científico não deve ser baseada em apenas uma medida bibliométrica, mas em associação de medidas. O FI e o índice H se baseiam fundamentalmente no número de citações dos artigos científicos, e este parâmetro, apesar de importante, não deve ser utilizado sozinho e tampouco supervalorizado na avaliação do mérito docente.

Partial adherence in Internet smoking cessation interventions presents treatment and evaluation challenges. Increasing adherence may improve outcomes. To present smoking outcomes from an Internet randomized trial of two strategies to encourage adherence to tobacco dependence treatment components: (i) a social network (SN) strategy to integrate smokers into an online community and (ii) free nicotine replacement therapy (NRT). In addition to intent-to-treat analyses, we used novel statistical methods to distinguish the impact of treatment assignment from treatment utilization. A total of 5,290 current smokers on a cessation website (WEB) were randomized to WEB, WEB + SN, WEB + NRT, or WEB + SN + NRT. The main outcome was 30-day point prevalence abstinence at 3 and 9 months post-randomization. Adherence measures included self-reported medication use (meds), and website metrics of skills training (sk) and community use (comm). Inverse Probability of Retention Weighting and Inverse Probability of Treatment Weighting jointly addressed dropout and treatment selection. Propensity weights were used to calculate Average Treatment effects on the Treated. Treatment assignment analyses showed no effects on abstinence for either adherence strategy. Abstinence rates were 25.7%-32.2% among participants that used all three treatment components (sk+comm +meds).Treatment utilization analyses revealed that among such participants, sk+comm+meds yielded large percentage point increases in 3-month abstinence rates over sk alone across arms: WEB = 20.6 (95% CI = 10.8, 30.4), WEB + SN = 19.2 (95% CI = 11.1, 27.3), WEB + NRT = 13.1 (95% CI = 4.1, 22.0), and WEB + SN + NRT = 20.0 (95% CI = 12.2, 27.7). Novel propensity weighting approaches can serve as a model for establishing efficacy of Internet interventions and yield important insights about mechanisms. NCT01544153.

Catastrophic flooding is responsible for more loss of life and damages to property than any other natural hazard. Recently developed flood inundation mapping technologies make it possible to view the extent and depth of flooding on the land surface over the Internet; however, by themselves these technologies are unable to provide estimates of losses to property and infrastructure. The Federal Emergency Management Agency's (FEMA's) HAZUS-MH software is extensively used to conduct flood loss analyses in the United States, providing a nationwide database of population and infrastructure at risk. Unfortunately, HAZUS-MH requires a dedicated Geographic Information System (GIS) workstation and a trained operator, and analyses are not adapted for convenient delivery over the Web. This article describes a cooperative effort by the US Geological Survey (USGS) and FEMA to make HAZUS-MH output GIS and Web compatible and to integrate these data with digital flood inundation maps in USGS's newly developed Inundation Mapping Web Portal. By running the computationally intensive HAZUS-MH flood analyses offline and converting the output to a Web-GIS compatible format, detailed estimates of flood losses can now be delivered to anyone with Internet access, thus dramatically increasing the availability of these forecasts to local emergency planners and first responders.

Toxicology in Malaysia has experienced rapid development and made great progress in education and research in conjunction with economic development in Malaysia over the past two decades. The main objectives of this study were to analyse the research originating from Malaysia and published in toxicology journals and to examine the authorship pattern and the citations retrieved from the Scopus database. Data from 1 January 2003 till 31 December 2012 were searched for documents with specific words in the toxicology field as a 'source title' and Malaysia as an affiliation country. Research productivity was evaluated based on a methodology we developed and used in other bibliometric studies by analysing: (a) total and trends of contributions in toxicology fields between 2003 and 2012; (b) Malaysian authorship pattern and productivity; (c) collaboration patterns; (d) journals in which Malaysian researchers publish; (e) the classification of journals to Institute for Scientific Information (ISI) or non-ISI; (f) impact factors (IFs) of all publications; and (g) citations received by the publications. In total, 290 documents were retrieved from 55 international peer-reviewed toxicology journals. The quantity of publication increased by around 10-fold from 2003 to 2012. The h-index of the retrieved documents was 20. Of the 55 journal titles, 42 (76.4%) have their IF listed in the journal citation reports 2012. Forty-two documents (14.5%) were published in journals that had no official IF. The total number of citations, at the time of manuscript writing (5 August 2013), was 1707, with a median (interquartile range) of 3 (0-7). Malaysia collaborated mostly with countries in the Asia-Pacific regions (18.3%), especially India and Japan, followed by the Middle East and Africa (10.0%), especially Palestine and Yemen. The present data show a promising rise and a good start for toxicology research activity in Malaysia. The sharing of relevant research questions by developed and developing countries can lead to research opportunities in the field of toxicology. © The Author(s) 2014.

2009-02-01

A data monitoring committee (DMC) is often employed to assess trial progress and review safety data and efficacy endpoints throughout a trail. Interim analyses performed for the DMC should use data that are as complete and verified as possible. Such analyses are complicated when data verification involves subjective study endpoints or requires clinical expertise to determine each subject's status with respect to the study endpoint. Therefore, procedures are needed to obtain adjudicated data for interim analyses in an efficient manner. In the past, methods for handling such data included using locally reported results as surrogate endpoints, adjusting analysis methods for unadjudicated data, or simply performing the adjudication as rapidly as possible. These methods all have inadequacies that make their sole usage suboptimal. For a study of prophylaxis for invasive candidiasis, adjudication of both study eligibility criteria and clinical endpoints prior to two interim analyses was required. Because the study was expected to enroll at a moderate rate and the sponsor required adjudicated endpoints to be used for interim analyses, an efficient process for adjudication was required. We created a web-based endpoint adjudication system (WebEAS) that allows for expedited review by the endpoint adjudication committee (EAC). This system automatically identifies when a subject's data are complete, creates a subject profile from the study data, and assigns EAC reviewers. The reviewers use the WebEAS to review the subject profile and submit their completed review form. The WebEAS then compares the reviews, assigns an additional review as a tiebreaker if needed, and stores the adjudicated data. The study for which this system was originally built was administratively closed after 10 months with only 38 subjects enrolled. The adjudication process was finalized and the WebEAS system activated prior to study closure. Some website accessibility issues presented initially. However, once these issues were resolved, the reviewers found the system user-friendly and easy to navigate. Web-based data adjudication depends upon expeditious data collection and verification. Further, ability to use web-based technologies, in addition to clinical expertise, must be considered in selecting EAC members. The automated nature of this system makes it a practical mechanism for ensuring timely endpoint adjudication. The authors believe a similar approach could be useful for handling endpoint adjudication for future clinical trials.

Geoprocessing of large gridded data according to overlap with irregular landscape features is common to many large-scale ecological analyses. The geoknife R package was created to facilitate reproducible analyses of gridded datasets found on the U.S. Geological Survey Geo Data Portal web application or elsewhere, using a web-enabled workflow that eliminates the need to download and store large datasets that are reliably hosted on the Internet. The package provides access to several data subset and summarization algorithms that are available on remote web processing servers. Outputs from geoknife include spatial and temporal data subsets, spatially-averaged time series values filtered by user-specified areas of interest, and categorical coverage fractions for various land-use types.

The use and misuse of journal metrics and other citation indicators.

Pendlebury, David A

2009-01-01

This article reviews the nature and use of the journal impact factor and other common bibliometric measures for assessing research in the sciences and social sciences based on data compiled by Thomson Reuters. Journal impact factors are frequently misused to assess the influence of individual papers and authors, but such uses were never intended. Thomson Reuters also employs other measures of journal influence, which are contrasted with the impact factor. Finally, the author comments on the proper use of citation data in general, often as a supplement to peer review. This review may help government policymakers, university administrators, and individual researchers become better acquainted with the potential benefits and limitations of bibliometrics in the evaluation of research.

"-Omics" systems sciences are at the epicenter of personalized medicine and public health, and drivers of knowledge-based biotechnology innovation. Bioinformatics, a core component of omics research, is one of the disciplines that first employed Free/Libre Open Source Software (FLOSS), and thus provided a fertile ground for its further development. Understanding the use and characteristics of FLOSS deployed in the omics field is valuable for future innovation strategies, policy and funding priorities. We conducted a bibliometric, longitudinal study of the use of FLOSS in sepsis omics research from 2011 to 2015 in the United States, EU-28 and China. Because sepsis is an interdisciplinary field at the intersection of multiple omics technologies and medical specialties, it was chosen as a model innovation ecosystem for this empirical analysis, which used publicly available data. Despite development of and competition from proprietary commercial software, scholars in omics continue to employ FLOSS routinely, and independent of the type of omics technology they work with. The number of articles using FLOSS increased significantly over time in the EU-28, as opposed to the United States and China (R = 0.96, p = 0.004). Furthermore, in an era where sharing of knowledge is being strongly advocated and promoted by public agencies and social institutions, we discuss possible correlations between the use of FLOSS and various funding sources in omics research. These observations and analyses provide new insights into the use of FLOSS in sepsis omics research across three (supra)national regions. Further benchmarking studies are warranted for FLOSS trends in other omics fields and geographical settings. These could, in time, lead to the development of new composite innovation and technology use metrics in omics systems sciences and bioinformatics communities.

The practice of evidence-based medicine involves integrating the latest best available evidence into patient care decisions. Yet, critical barriers exist for clinicians' retrieval of evidence that is relevant for a particular patient from primary sources such as randomized controlled trials and meta-analyses. To help address those barriers, we investigated machine learning algorithms that find clinical studies with high clinical impact from PubMed®. Our machine learning algorithms use a variety of features including bibliometric features (e.g., citation count), social media attention, journal impact factors, and citation metadata. The algorithms were developed and evaluated with a gold standard composed of 502 high impact clinical studies that are referenced in 11 clinical evidence-based guidelines on the treatment of various diseases. We tested the following hypotheses: (1) our high impact classifier outperforms a state-of-the-art classifier based on citation metadata and citation terms, and PubMed's® relevance sort algorithm; and (2) the performance of our high impact classifier does not decrease significantly after removing proprietary features such as citation count. The mean top 20 precision of our high impact classifier was 34% versus 11% for the state-of-the-art classifier and 4% for PubMed's® relevance sort (p=0.009); and the performance of our high impact classifier did not decrease significantly after removing proprietary features (mean top 20 precision=34% vs. 36%; p=0.085). The high impact classifier, using features such as bibliometrics, social media attention and MEDLINE® metadata, outperformed previous approaches and is a promising alternative to identifying high impact studies for clinical decision support.

2016-08-24

Collaboration between Sub-Saharan African researchers is important for the generation and transfer of health technology assessment (HTA) evidence, in order to support priority-setting in health. The objective of this analysis was to evaluate collaboration patterns between countries. We conducted a rapid evidence assessment that included a random sample of health economic evaluations carried out in 20 countries (Angola, Botswana, Congo, Lesotho, Madagascar, Malawi, Mauritius, Mozambique, Namibia, Seychelles, South Africa, Swaziland, Tanzania, Zambia, Zimbabwe, Ghana, Kenya, Nigeria, Ethiopia, Uganda). We conducted bibliometric network analysis based on all first authors with a Sub-Saharan African academic affiliation and their co-authored publications ("network-articles"). Then we produced a connection map of collaboration patterns among Sub-Saharan African researchers, reflecting the number of network-articles and the country of affiliation of the main co-authors. The sample of 119 economic evaluations mostly related to treatments of communicable diseases, in particular HIV/AIDS (42/119, 35.29 %) and malaria (26/119, 21.85 %). The 39 first authors from Sub-Saharan African institutions together co-authored 729 network-articles. The network analysis showed weak collaboration between health economic researchers in Sub-Saharan Africa, with researchers being more likely to collaborate with Europe and North America than with other African countries. South Africa stood out as producing the highest number of health economic evaluations and collaborations. The development and evaluation of HTA research networks in Sub-Saharan Africa should be supported, with South Africa central to any such efforts. Organizations and institutions from high income countries interested in supporting priority setting in Sub-Saharan Africa should include promoting collaboration as part of their agendas, in order to take advantage of the potential transferability of results and methods of the available health economic analyses in Africa and internationally.

In recent years, the literature associated with healthcare big data has grown rapidly, but few studies have used bibliometrics and a visualization approach to conduct deep mining and reveal a panorama of the healthcare big data field. To explore the foundational knowledge and research hotspots of big data research in the field of healthcare informatics, this study conducted a series of bibliometric analyses on the related literature, including papers' production trends in the field and the trend of each paper's co-author number, the distribution of core institutions and countries, the core literature distribution, the related information of prolific authors and innovation paths in the field, a keyword co-occurrence analysis, and research hotspots and trends for the future. By conducting a literature content analysis and structure analysis, we found the following: (a) In the early stage, researchers from the United States, the People's Republic of China, the United Kingdom, and Germany made the most contributions to the literature associated with healthcare big data research and the innovation path in this field. (b) The innovation path in healthcare big data consists of three stages: the disease early detection, diagnosis, treatment, and prognosis phase, the life and health promotion phase, and the nursing phase. (c) Research hotspots are mainly concentrated in three dimensions: the disease dimension (e.g., epidemiology, breast cancer, obesity, and diabetes), the technical dimension (e.g., data mining and machine learning), and the health service dimension (e.g., customized service and elderly nursing). This study will provide scholars in the healthcare informatics community with panoramic knowledge of healthcare big data research, as well as research hotspots and future research directions.

Abstract Purpose: Using bibliometrics, we analyzed the research status of immune checkpoint blockade (ICB, a popular tumor immunotherapy method represented by antibodies targeted CTLA-4 and PD-1/PD-L1) in tumor immunotherapy in China during the past 2 decades. Methods: Articles in Science Citation Index Expanded (SCI-EXPANDED), patents in Thomson Innovation, and drugs in Cortellis Competitive Intelligence in the field of ICB for tumor immunotherapy from 1996 to 2015 were the subjects of bibliometric analysis. Using database-attached software and Excel, quantitative analyses were performed including examination of the number of documents, citation frequency, h-index, key projects, quantity of publications, public patents, and status of new drug research. Results: The number of publications from 1996 to 2015 in the field of ICB for tumor immunotherapy that came out of China was 380, which was 14.3% of the total publications worldwide and was second only to that of the USA. In the past decade, China has rapidly increased the number of publications and patents in this field. However, indicators of publication influence, such as citation frequency and h-index, were far behind other advanced countries. In addition, the total number of patents in China was much lower than that of the USA. China has introduced 5 drugs for ICB that are being developed for the healthcare market. Conclusion: Tumor immunotherapy research such as ICB in China has developed rapidly with increasing influence in the last 2 decades. However, there is still a relatively large gap compared with the USA. It is expected that China will have greater influence on tumor immunotherapy research in the near future. PMID:29642147

Tissue engineering is defined as a multidisciplinary scientific discipline with the main objective to develop artificial bioengineered living tissues in order to regenerate damaged or lost tissues. Since its appearance in 1988, tissue engineering has globally spreaded in order to improve current therapeutical approaches, entailing a revolution in clinical practice. The aim of this study is to analyze global research trends on tissue engineering publications in order to realize the scenario of tissue engineering research from 1991 to 2016 by using document retrieval from Web of Science database and bibliometric analysis. Document type, language, source title, authorship, countries and filiation centers and citation count were evaluated in 31,859 documents. Obtained results suggest a great multidisciplinary role of tissue engineering due to a wide spectrum -up to 51- of scientific research areas identified in the corpus of literature, being predominant technological disciplines as Material Sciences or Engineering, followed by biological and biomedical areas, as Cell Biology, Biotechnology or Biochemistry. Distribution of authorship, journals and countries revealed a clear imbalance in which a minority is responsible of a majority of documents. Such imbalance is notorious in authorship, where a 0.3% of authors are involved in the half of the whole production.

to characterize the scientific contribution nursing has made regarding coverage, universal access and equity in health, and to understand this production in terms of subjects and objects of study. this was cross-sectional, documentary research; the units of analysis were 97 journals and 410 documents, retrieved from the Web of Science in the category, "nursing". Descriptors associated to coverage, access and equity in health, and the Mesh thesaurus, were applied. We used bibliometric laws and indicators, and analyzed the most important articles according to amount of citations and collaboration. the document retrieval allowed for 25 years of observation of production, an institutional and an international collaboration of 31% and 7%, respectively. The mean number of coauthors per article was 3.5, with a transience rate of 93%. The visibility index was 67.7%, and 24.6% of production was concentrated in four core journals. A review from the nursing category with 286 citations, and a Brazilian author who was the most productive, are issues worth highlighting. the nursing collective should strengthen future research on the subject, defining lines and sub-lines of research, increasing internationalization and building it with the joint participation of the academy and nursing community.

Contemporary psychology and women: A gender analysis of the scientific production.

González-Álvarez, Julio; Cervera-Crespo, Teresa

Despite important advances made in recent decades, women are still underrepresented in science (less than 30% of authorships). This study presents a bibliometric analysis of all the Psychology articles published in 2009 included in the Web of Science database (Thomson Reuters) in order to examine the contribution of women in contemporary Psychology, their pattern of research collaboration, the scientific content and the scientific impact from a gender perspective. From a total of 90,067 authorships, gender could be identified in 74,413 (82.6%) of them, being 40,782 (54.8%) male authorships and 33,631 (45.2%) female authorships. These data corresponded to 24,477 (49.9%) individual men and 24,553 (50.1%) women, respectively. Therefore, Psychology presents gender parity in the number of authors, and a gender asymmetry in the number of authorships that it is much lower than in science in general and other specific scientific fields. In relative terms, women tend to be concentrated in the first position of the authorship by-line and much less in the last (senior) position. This double pattern suggests that age probably plays a role in (partly) explaining the slight gender disparity of authorships. © 2017 International Union of Psychological Science.

Citations to articles published in academic journals represent a proxy for influence in bibliometrics. To measure the journal impact factor for Progress in Transplantation over time and to also identify related journals indexed in transplantation and surgery. Data from Journal Citation Reports (ISI web of science) were used to rank Progress in Transplantation compared to peer journals using journal impact and journal relatedness measures. Social network analysis was used to measure relationships between pairs of journals in Progress in Transplantation's relatedness network. Journal impact factor and journal relatedness. Data from 2010 through 2015 indicate the average journal article in PIT was cited 0.87 times (standard deviation [SD] = 0.12) and this estimate was stable over time. Progress in Transplantation most often cited American Journal of Transplantation, Transplantation, American Journal of Kidney Diseases, and Liver Transplantation. In terms of cited data, the journal was most often referenced by Clinical Transplantation, Transplant International, and Current Opinion in Organ Transplantation. The journal is listed both in surgery and transplantation categories of Journal Citation Reports and its impact factors over time fare better with surgery journals than with transplant journals. Network data using betweenness centrality indicate Progress in Transplantation links transplantation-focused journals and journals indexed in health sciences categories.

The study of science at the individual scholar level requires the disambiguation of author names. The creation of author's publication oeuvres involves matching the list of unique author names to names used in publication databases. Despite recent progress in the development of unique author identifiers, e.g., ORCID, VIVO, or DAI, author disambiguation remains a key problem when it comes to large-scale bibliometric analysis using data from multiple databases. This study introduces and tests a new methodology called seed + expand for semi-automatic bibliographic data collection for a given set of individual authors. Specifically, we identify the oeuvre of a set of Dutch full professors during the period 1980-2011. In particular, we combine author records from a Dutch National Research Information System (NARCIS) with publication records from the Web of Science. Starting with an initial list of 8,378 names, we identify 'seed publications' for each author using five different approaches. Subsequently, we 'expand' the set of publications in three different approaches. The different approaches are compared and resulting oeuvres are evaluated on precision and recall using a 'gold standard' dataset of authors for which verified publications in the period 2001-2010 are available.

The analytical approach to the work was inspired by previous work by the same team to measure and predict the scientific prominence of terms and entities within specific research domains. The goal was to create tools that could assist domain-knowledgeable analysts in investigating the history and path of technological developments in general, with a focus on analyzing step-function changes in performance,more » or “breakthroughs,” in particular. The text-analytics platform developed during this project was dubbed Helios. The project relied on computational methods for analyzing large corpora of technical documents. For this project we ingested technical documents from the following sources into Helios: Thomson Scientific Web of Science (papers), the U.S. Patent & Trademark Office (patents), the U.S. Department of Energy (technical documents), the U.S. National Science Foundation (project funding summaries), and a hand curated set of full-text documents from Thomson Scientific and other sources.« less

There is a paucity of information about the relationship of forensic odontology with various dental specialties in the articles published in the Journal of Forensic Odonto-Stomatology. This study aimed to find the relationship of forensic odontology with various dental specialties in the articles published in the Journal of Forensic Odonto-Stomatology from 2005 to 2012 over an 8-year period. Bibliometric analysis was performed using web-based search during December 2013. Out of the total 97 published articles, the maximum number of published articles were related to oral medicine and radiology (20) and community dentistry (20), followed by orthodontics (18), prosthodontics (15), and oral pathology and microbiology (8), pedodontics (7), oral and maxillofacial surgery (4) and conservative dentistry and endodontics (3). Among the articles published in Journal of Forensic Odonto-Stomatology, mass disasters (10) and bite mark analysis (10), followed by sexual dimorphism (8) and dental fraud and malpractice (8), followed by craniofacial superimposition (6) and identification (6) form the major attraction of the contributors. This paper has tried to evaluate the new working classification proposed for forensic odontology based on its relationship with other dental specialties.

Discrete Lognormal Model as an Unbiased Quantitative Measure of Scientific Performance Based on Empirical Citation Data

2013-03-01

Assessing the career performance of scientists has become essential to modern science. Bibliometric indicators, like the h-index are becoming more and more decisive in evaluating grants and approving publication of articles. However, many of the more used indicators can be manipulated or falsified by publishing with very prolific researchers or self-citing papers with a certain number of citations, for instance. Accounting for these factors is possible but it introduces unwanted complexity that drives us further from the purpose of the indicator: to represent in a clear way the prestige and importance of a given scientist. Here we try to overcome this challenge. We used Thompson Reuter's Web of Science database and analyzed all the papers published until 2000 by ~1500 researchers in the top 30 departments of seven scientific fields. We find that over 97% of them have a citation distribution that is consistent with a discrete lognormal model. This suggests that our model can be used to accurately predict the performance of a researcher. Furthermore, this predictor does not depend on the individual number of publications and is not easily ``gamed'' on. The authors acknowledge support from FCT Portugal, and NSF grants

ABSTRACTThis study analyzed and assessed publication trends in articles on "disaster medicine," using scientometric analysis. Data were obtained from the Web of Science Core Collection (WoSCC) of Thomson Reuters on March 27, 2017. A total of 564 publications on disaster medicine were identified. There was a mild increase in the number of articles on disaster medicine from 2008 (n=55) to 2016 (n=83). Disaster Medicine and Public Health Preparedness published the most articles, the majority of articles were published in the United States, and the leading institute was Tohoku University. F. Della Corte, M. D. Christian, and P. L. Ingrassia were the top authors on the topic, and the field of public health generated the most publications. Terms analysis indicated that emergency medicine, public health, disaster preparedness, natural disasters, medicine, and management were the research hotspots, whereas Hurricane Katrina, mechanical ventilation, occupational medicine, intensive care, and European journals represented the frontiers of disaster medicine research. Overall, our analysis revealed that disaster medicine studies are closely related to other medical fields and provides researchers and policy-makers in this area with new insight into the hotspots and dynamic directions.

The Amazon region has been part of climate change debates for decades, yet attention to its social and health dimensions has been limited. This paper assesses literature on the social and health dimensions of climate change in the Amazon. A conceptual framework underscores multiple stresses and exposures created by interactions between climate change and local social-environmental conditions. Using the Thomson-Reuter Web of Science, this study bibliometrically assessed the overall literature on climate change in the Amazon, including Physical Sciences, Social Sciences, Anthropology, Environmental Science/Ecology and Public, Environmental/Occupational Health. From this assessment, a relevant sub-sample was selected and complemented with literature from the Brazilian database SciELO. This sample discusses three dimensions of climate change impacts in the region: livelihood changes, vector-borne diseases and microbial proliferation, and respiratory diseases. This analysis elucidates imbalance and disconnect between ecological, physical and social and health dimensions of climate change and between continental and regional climate analysis, and sub-regional and local levels. Work on the social and health implications of climate change in the Amazon falls significantly behind other research areas, limiting reliable information for analytical models and for Amazonian policy-makers and society at large. Collaborative research is called for.

Measuring Scholastic Production by Dermatopathologists Using the H-Index: A Cross-Sectional Study.

PubMed

Fraga, Garth R

2018-06-01

Academic advancement in dermatopathology requires evidence of scientific production. The H-index is a useful bibliometric for measuring scientific production because it weights both volume and impact of an individual's scholastic production. The H-index distribution among academic dermatopathologists is unknown. In this cross-sectional study of 299 dermatopathologists with academic appointments in North America, H-index, publication counts, and citation counts were retrieved from Thomas Reuters Web of Science. Analytic statistics were performed to identify best predictors of academic rank and cutoff points between academic ranks. The H-index was a superior predictor of overall academic rank than publication or citation counts. The median H-index for assistant, associate, and full professors was 4, 6, and 11, respectively. H-index cutoff scores of 8 and 10 favored associate and full professor rank, respectively. These data provide benchmarks for dermatopathologists to gauge their scientific productivity against that of their peers. Although advancement decisions will depend on a careful examination of the scope and impact of a candidate's work, assistant professors of dermatopathology with H-index scores of >7 and associate professors of dermatopathology with H-index scores of >9 may wish to consider application for promotion.

Technologies that are set to increase the productivity of agricultural practices require more and more data. Nevertheless, farming data is also being increasingly cheap to collect and maintain. Bulk of data that are collected by the sensors and samples need to be analysed in an efficient and transparent manner. Web technologies have long being used to develop applications that can assist the farmers and managers. However until recently, analysing the data in an online environment has not been an easy task especially in the eyes of data analysts. This barrier is now overcome by the availability of new application programming interfaces that can provide real-time web based data analysis. In this paper developing a prototype web based application for data analysis using new facilities in R statistical package and its web development facility, Shiny is explored. The pros and cons of this type of data analysis environment for precision farming are enumerated and future directions in web application development for agricultural data are discussed.

The current structure of key actors involved in research on land and soil degradation

Land and soil conservation topics, the final mandate of the United Convention to Combat desertification in drylands, have been diagnosed as still suffering from a lack of guidance. On the contrary, climate change and biodiversity issues -the other two big subjects of the Rio Conventions- seem to progress and may benefit from the advice of international panels. Arguably the weakness of policy measures and hence the application of scientific knowledge by land users and stakeholders could be the expression of an inadequate research organization and a lack of ability to channel their findings. In order to better understand the size, breadth and depth of the scientific communities involved in providing advice to this convention and to other bodies, this study explores the corpus of international publications dealing with land and/or with soils. A database of several thousands records including a significant part of the literature published so far was performed using the Web of Science and other socio-economic databases such as FRANCIS and CAIRN. We extracted hidden information using bibliometric methods and data mining applied to these scientific publications to map the key actors (laboratories, teams, institutions) involved in research on land and on soils. Several filters were applied to the databases in combination with the word "desertification". The further use of Tetralogie software merges databases, analyses similarities and differences between keywords, disciplines, authors and regions and identifies obvious clusters. Assessing their commonalities and differences, the visualisation of links and gaps between scientists, organisations, policymakers and other stakeholders is possible. The interpretation of the 'clouds' of disciplines, keywords, and techniques will enhance the understanding of interconnections between them; ultimately this will allow diagnosing some of their strengths and weaknesses. This may help explain why land and soil degradation remains a serious global problem that lacks sufficient attention. We hope that this study will contribute to clarify the scientific landscape at stake to remediate possible weaknesses in the future.

Contemporary Cuban Physics Through Scientific Publications: An Insider’s View

Altshuler, Ernesto

In a previous paper, the author reached some conclusions on the tendencies of the publications by Cuban physicists in international journals (Altshuler, Rev Cub Fís 22(2):173-182, 2005) and called for a systematic bibliometric study of the subject. Such a study has now been undertaken (a contribution to this volume entitled "Physics in Cuba from the Perspective of Bibliometrics" by Werner Marx and Manuel Cardona, referred to in this paper as Marx and Cardona) and supports the main conclusions of the former work. The scenario of Cuban physics since 1995 has been conditioned by two main facts interacting in a nontrivial way: the serious material shortages affecting local physics laboratories and bibliographic resources, and an increase in the country's international collaboration. As a positive result, the total volume of Cuban publications in international physics journals has increased since 1995, perhaps reaching a peak around the year 2000, while the number of citations of Cuban papers and the impact of the journals in which they were published have continued to increase since the mid-1990s. Theoretical work produced by physicists from a number of Cuban institutions in international collaborations strongly contribute to those numbers. In the last years, international publications suggest a `self-organized' opening of Cuban physics towards interdisciplinary subjects, which is increasing the `bibliometric visibility' of autochthonous experimental work.

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

Objective To identify the elite of authors about the subject adherence to antiretroviral therapy; to identify the journals turned to publishing articles about adherence to antiretroviral therapy; and to identify and analyze the most commonly used words in abstracts of articles about adherence to antiretroviral therapy. Method A bibliometric study conducted through the Scopus base. We used articles published between 1996 and 2014, after application of the eligibility criteria, there were composed the sample with 24 articles. The data were analyzed descriptively. Were used the laws of bibliometric (Lotka, Bradford and Zipf) and the conceptual cloud map of words, through the program Cmap tools. Results Lotka’s Law identified the 5 authors more productive (46% of the total published). Bradford is impaired in this study. Concerning Zipf, 3 zones were determined, 31.47% of the words with in the first zone, 26.46% in the second and 42.06% in the third. In the conceptual map, the words/factors that positively and negatively influence adherence were emphasized, among them the need for more research in the health services. Conclusion There are few publications about the accession to antiretroviral therapy, and the scientific production is in the process of maturation. One can infer that the theme researched is not yet an obsolete topic. It should be noted that the Bibliometric was a relevant statistic tool to generate information about the publications about the antiretroviral therapy. PMID:28979571

Digital Presence of Norwegian Scholars on Academic Network Sites—Where and Who Are They?

2015-01-01

The use of academic profiling sites is becoming more common, and emerging technologies boost researchers’ visibility and exchange of ideas. In our study we compared profiles at five different profiling sites. These five sites are ResearchGate, Academia.edu, Google Scholar Citations, ResearcherID and ORCID. The data set is enriched by demographic information including age, gender, position and affiliation, which are provided by the national CRIS-system in Norway. We find that approximately 37% of researchers at the University of Bergen have at least one profile, the prevalence being highest (> 40%) for members at the Faculty of Psychology and the Faculty of Social Sciences. Across all disciplines, ResearchGate is the most widely used platform. However, within Faculty of Humanities, Academia.edu is the preferred one. Researchers are reluctant to maintain multiple profiles, and there is little overlap between different services. Age turns out to be a poor indicator for presence in the investigated profiling sites, women are underrepresented and professors together with PhD students are the most likely profile holders. We next investigated the correlation between bibliometric measures, such as publications and citations, and user activities, such as downloads and followers. We find different bibliometric indicators to correlate strongly within individual platforms and across platforms. There is however less agreement between the traditional bibliometric and social activity indicators. PMID:26565408

A Bibliometric Analysis of Climate Engineering Research

2013-12-01

The past five years have seen a dramatic increase in the number of media and scientific publications on the topic of climate engineering, or geoengineering, and some scientists are increasingly calling for more research on climate engineering as a possible supplement to climate change mitigation and adaptation strategies. In this context, understanding the current state of climate engineering research can help inform policy discussions and guide future research directions. Bibliometric analysis - the quantitative analysis of publications - is particularly applicable to fields with large bodies of literature that are difficult to summarize by traditional review methods. The multidisciplinary nature of the published literature on climate engineering makes it an ideal candidate for bibliometric analysis. Publications on climate engineering are found to be relatively recent (more than half of all articles during 1988-2011 were published since 2008), include a higher than average percentage of non-research articles (30% compared with 8-15% in related scientific disciplines), and be predominately produced by countries located in the Northern Hemisphere and speaking English. The majority of this literature focuses on land-based methods of carbon sequestration, ocean iron fertilization, and solar radiation management and is produced with little collaboration among research groups. This study provides a summary of existing publications on climate engineering, a perspective on the scientific underpinnings of the global dialogue on climate engineering, and a baseline for quantitatively monitoring the development of climate engineering research in the future.

To find out the prevalence of quality trust marks present in websites and to analyse the quality of these websites displaying trust marks compared with those that do not display them, in order to put forward these trust marks as a quality indicator. Cross-sectional study. Internet. Websites on vaccines. Using "vacunas OR vaccines" as key words, the features of 40 web pages were analysed. These web pages were selected from the page results of two search engines, Google and Yahoo! Based on a total of 9 criteria, the average score of criteria fulfilled was 7 (95% CI 3.96-10.04) points for the web pages offered by Yahoo! and 7.3 (95% CI 3.86-10.74) offered by Google. Amongst web pages offered by Yahoo!, there were three with clearly inaccurate information, while there were four in the pages offered by Google. Trust marks were displayed in 20% and 30% medical web pages, respectively, and their presence reached statistical significance (P=0.033) when fulfilling the quality criteria compared with web pages where trust marks were not displayed. A wide variety of web pages was obtained by search engines and a large number of them with useless information. Although the websites analysed had a good quality, between 15% and 20% showed inaccurate information. Websites where trust marks were displayed had more quality than those that did not display one and none of them were included amongst those where inaccurate information was found.

The bibliometrics of atmospheric environment

NASA Astrophysics Data System (ADS)

Brimblecombe, Peter; Grossi, Carlota M.

Bibliometric analysis is an important tool in the management of a journal. SCOPUS output is used to assess the increase in the quantity of material in Atmospheric Environment and stylistic changes in the way authors choose words and punctuation in titles and assemble their reference lists. Citation analysis is used to consider the impact factor of the journal, but perhaps more importantly the way in which it reflects the importance authors give to papers published in Atmospheric Environment. The impact factor of Atmospheric Environment (2.549 for 2007) from the Journal Citation Reports suggests it performs well within the atmospheric sciences, but it conceals the long term value authors place on papers appearing in the journal. Reference lists show that a fifth come through citing papers more than a decade old.

Bibliometry is a quantitative statistical technique to measure levels of production and dissemination of knowledge, as well as a useful tool to track the development of an scientific area. The valuation of production required for recognition of researchers and magazines is accomplished through tools called bibliometricindexes, divided into quality indicators and scientific impact. Initially developed for monographs of statistical measures especially in libraries, today bibliometrics is mainly used to evaluate productivity of authors and citation repercussion. However, these tools have limitations and sometimes provoke controversies about indiscriminate application, leading to the development of newer indexes. It is important to know the most common search indexes and use it properly even acknowledging its limitations as it has a direct impact in their daily practice, reputation and funds achievement.

Hirt, Julian; Buhtz, Christian; Mersdorf, Benedikt; Meyer, Gabriele

2018-02-01

Background: The frequency of publications by nursing scientists from the German-speaking area in journals with a high impact factor is an indicator for participation of the discipline in the international discourse. Previous publication analyses focused on nursing science journals only and regularly found an underrepresentation of experimental studies and clinical topics. Aim: To identify and analyse the number of publications by nursing scientists from Germany, Austria and German-speaking Switzerland in international high impact journals. Method: The Journal Citation Reports were used to identify nursing relevant categories of journals in which the highest 10 % of the years 2010 to 2014 were selected according to the 5-year Impact Factor. Inclusion of publications and data extraction were carried out by two independent persons. Results: 106939 publications from 126 journals were screened; 100 publications were identified with 229 contributions by 114 nursing scientists. 42 % of studies are observational and 11 % are experimental. The majority of studies are clinically oriented (55 %). More than 50 % have been published in the past two years. Conclusions: The number of publications by nursing scientists from the German-speaking countries in High Impact Journals is low. There is an increase throughout the observation period. In opposite to former analyses a higher proportion of clinical research has been found.

The writing of a thesis has 2 main objectives: the appropriate training to be a good researcher and the publication of the first original research work. This study attempted to check this statement applied to theses in Otolaryngology by analysing the variation in the authors' publications. We used the database TESEO to obtain the data relative to Otolaryngology theses in Spain published between 1993 and 2003. We found the publications of each author by using de programme "Publish or Perish" and we analysed the variations in their work in 3 periods (prior to, around and after thesis publication). The publications, the citations and the parameters analysed all increased in the second and third periods (around and after) with regard to the first period. However, there were no significant differences in some of them in the first 2 periods. The elaboration of a thesis in Otolaryngology increased the scientific production of its author. Almost a third of the authors did not publish any work. There was a significant increase in all the parameters studied and the bibliometric indices between the period before thesis publication and the around and after thesis periods.

Service substitution is an important research topic in the fields of Web services and service-oriented computing. This work presents a novel method to analyse and substitute Web services. A new concept, called a Service Cluster Net Unit, is proposed based on Web service clusters. A service cluster is converted into a Service Cluster Net Unit. Then it is used to analyse whether the services in the cluster can satisfy some service requests. Meanwhile, the substitution methods of an atomic service and a composite service are proposed. The correctness of the proposed method is proved, and the effectiveness is shown and compared with the state-of-the-art method via an experiment. It can be readily applied to e-commerce service substitution to meet the business automation needs.

The transition of a large-scale quality improvement initiative: a bibliometric analysis of the Productive Ward: Releasing Time to Care programme.

To examine the literature related to a large-scale quality improvement initiative, the 'Productive Ward: Releasing Time to Care', providing a bibliometric profile that tracks the level of interest and scale of roll-out and adoption, discussing the implications for sustainability. Productive Ward: Releasing Time to Care (aka Productive Ward) is probably one of the most ambitious quality improvement efforts engaged by the UK-NHS. Politically and financially supported, its main driver was the NHS Institute for Innovation and Improvement. The NHS institute closed in early 2013 leaving a void of resources, knowledge and expertise. UK roll-out of the initiative is well established and has arguably peaked. International interest in the initiative however continues to develop. A comprehensive literature review was undertaken to identify the literature related to the Productive Ward and its implementation (January 2006-June 2013). A bibliometric analysis examined/reviewed the trends and identified/measured interest, spread and uptake. Overall distribution patterns identify a declining trend of interest, with reduced numbers of grey literature and evaluation publications. However, detailed examination of the data shows no reduction in peer-reviewed outputs. There is some evidence that international uptake of the initiative continues to generate publications and create interest. Sustaining this initiative in the UK will require re-energising, a new focus and financing. The transition period created by the closure of its creator may well contribute to further reduced levels of interest and publication outputs in the UK. However, international implementation, evaluation and associated publications could serve to attract professional/academic interest in this well-established, positively reported, quality improvement initiative. This paper provides nurses and ward teams involved in quality improvement programmes with a detailed, current-state, examination and analysis of the Productive Ward literature, highlighting the bibliometric patterns of this large-scale, international, quality improvement programme. It serves to disseminate updated publication information to those in clinical practice who are involved in Productive Ward or a similar quality improvement initiative. © 2014 John Wiley & Sons Ltd.

Evaluation of unique identifiers used as keys to match identical publications in Pure and SciVal - a case study from health science.

Unique identifiers (UID) are seen as an effective key to match identical publications across databases or identify duplicates in a database. The objective of the present study is to investigate how well UIDs work as match keys in the integration between Pure and SciVal, based on a case with publications from the health sciences. We evaluate the matching process based on information about coverage, precision, and characteristics of publications matched versus not matched with UIDs as the match keys. We analyze this information to detect errors, if any, in the matching process. As an example we also briefly discuss how publication sets formed by using UIDs as the match keys may affect the bibliometric indicators number of publications, number of citations, and the average number of citations per publication.  The objective is addressed in a literature review and a case study. The literature review shows that only a few studies evaluate how well UIDs work as a match key. From the literature we identify four error types: Duplicate digital object identifiers (DOI), incorrect DOIs in reference lists and databases, DOIs not registered by the database where a bibliometric analysis is performed, and erroneous optical or special character recognition. The case study explores the use of UIDs in the integration between the databases Pure and SciVal. Specifically journal publications in English are matched between the two databases. We find all error types except erroneous optical or special character recognition in our publication sets. In particular the duplicate DOIs constitute a problem for the calculation of bibliometric indicators as both keeping the duplicates to improve the reliability of citation counts and deleting them to improve the reliability of publication counts will distort the calculation of average number of citations per publication. The use of UIDs as a match key in citation linking is implemented in many settings, and the availability of UIDs may become critical for the inclusion of a publication or a database in a bibliometric analysis.

Fragment-based drug discovery (FBDD) is a highly interdisciplinary field, rich in ideas integrated from pharmaceutical sciences, chemistry, biology, and physics, among others. To enrich our understanding of the development of the field, we used bibliometric techniques to analyze 3642 publications in FBDD, complementing accounts by key practitioners. Mapping its core papers, we found the transfer of knowledge from academia to industry. Co-authorship analysis showed that university-industry collaboration has grown over time. Moreover, we show how ideas from other scientific disciplines have been integrated into the FBDD paradigm. Keyword analysis showed that the field is organized into four interconnected practices: library design, fragment screening, computational methods, and optimization. This study highlights the importance of interactions among various individuals and institutions from diverse disciplines in newly emerging scientific fields. Copyright © 2018.

Using a bibliometric approach an analysis was made of the scientific publications of Spanish investigators in the area of optometry, from 1974 until 2013. The EMBASE database was used for this study, employing optomtr*, optic*, visual, vision, eye*, and ophthalm* as search terms. The most common bibliometric indicators were applied for the selected publications. The number of published articles retrieved for Spain from 1974-2013 was 1,055. The growth of publications was more exponential (R=0.93) than linear (R= 0.71). The doubling time of scientific production was 3.63 years. The level of productivity primarily corresponded to small producers (Transience index of 64%). The collaboration index was 4.4 authors per paper. The majority of the output was generated in academic settings (62.27%). The Bradford core was formed by four journals, in which Optometry and Vision Science accounted for the majority of publications, with 11.85%. Research in the area of optometry in Spain is in a phase of exponential growth, containing a high level of transient authors, which may indicate either a low productivity or the presence of investigators from other related fields that have published in a sporadic manner in this area. A small number of research groups are responsible for producing the majority of articles, primarily in an academic setting. There is a high concentration of publications in a few journals.

A bibliometric analysis was conducted to evaluate groundwater research from different perspectives in the period 1993-2012 based on the Science Citation Index-Expanded (SCIE) database. The bibliometric analysis summarizes output, categorical, geographical, and institutional patterns, as well as research hotspots in global groundwater studies. Groundwater research experienced notable growth in the past two decades. ;Environmental sciences;, ;water resources; and ;multidisciplinary geosciences; were the three major subject categories. The Journal of Hydrology published the largest number of groundwater-related publications in the surveyed period. Major author clusters and research regions are located in the United States, Western Europe, Eastern and Southern Asia, and Eastern Australia. The United States was a leading contributor to global groundwater research with the largest number of independent and collaborative papers, its dominance affirmed by housing 12 of the top 20 most active institutions reporting groundwater-related research. The US Geological Survey, the Chinese Academy of Sciences, and the USDA Agricultural Research Service were the three institutions with the largest number of groundwater-related publications. A keywords analysis revealed that groundwater quality and contamination, effective research technologies, and treatment technologies for water-quality improvement were the main research areas in the study period. Several keywords such as ;arsenic;, ;climate change;, ;fluoride;, ;groundwater management;, ;hydrogeochemistry;, ;uncertainty;, ;numerical modeling;, ;seawater intrusion;, ;adsorption;, ;remote sensing;, ;land use;, ;USA;(as study site), and ;water supply; received dramatically increased attention during the study period, possibly signaling future research trends.

The governments and organizations responsible for scientific policies try to encourage equality of gender, among their priorities that of obtaining equal participation and full integration of women in all aspects of the scientific profession. The study analyzes the scientific production of women in the areas of Psychiatry by means of the bibliometric study of the papers published in ACTAS ESPANOLAS DE PSIQUIATRIA. A total of 458 papers published from 1999- 2006 period were downloaded from the Science Citation Index-Expanded database, these including original research papers, review articles and clinical cases. A bibliometric study broken down by gender was carried out to determine the existence or inequalities between men and women regarding scientific productivity, type of document, order of author signatures, on the institutional and geographical level. The papers were published by 1,194 different authors. The gender of 977 authors was identified, 587 (60.08%) men and 390 (39.92%) women. The percentage of women authorship has risen from 29.92% in 1999 to 38.86% in 2006. A total of 42.92% of authors having one published article were women, while (those with more than nine articles) only accounted for 33%. Bibliometric studies on scientific activity provide essential information to promote gender equality. An annual increase over 1% in the number of female authors in the journal has been observed, which if it continues will lead to a parity in coming years.

Career development tips for today's nursing academic: bibliometrics, altmetrics and social media.

Smith, Derek R; Watson, Roger

2016-11-01

A discussion of bibliometrics, altmetrics and social media for the contemporary nursing scholar and academic researcher. Today's nursing academic faces myriad challenges in balancing their daily life and, in recent years, academic survival has been increasingly challenged by the various research assessment exercises that evaluate the performance of knowledge institutions. As such, it is essential that today's nursing academic keep up to date with the core competencies needed for survival in a modern research career, particularly the intersecting triad of bibliometrics, altmetrics and social media. Discussion paper. Published literature and relevant websites. The rise of social media and altmetrics has important implications for contemporary nursing scholars who publish their research. Some fundamental questions when choosing a journal might be 'does it have a Twitter and/or Facebook site, or a blog (or all three)'; and 'does it have any other presence on social media, such as LinkedIn, Wikipedia, YouTube, ResearchGate and so on?' Another consequence of embracing social media is that individual academics should also develop their own strategies for promoting and disseminating their work as widely as possible. The rising importance of social media and altmetrics can no longer be ignored, and today's nursing academic now has another facet to consider in their scholarly activities. Despite the changing nature of research dissemination, however, it is still important to recognize the undoubted value of established knowledge dissemination routes (that being the peer-reviewed publication). © 2016 John Wiley & Sons Ltd.

There is a recognized challenge in analyzing traditional Chinese medicine formulas because of their complex chemical compositions. The application of modern analytical techniques such as high-performance liquid chromatography coupled with a tandem mass spectrometry has improved the characterization of various compounds from traditional Chinese medicine formulas significantly. This study aims to conduct a bibliometric analysis to recognize the overall trend of high-performance liquid chromatography coupled with tandem mass spectrometry approaches in the analysis of traditional Chinese medicine formulas, its significance and possible underlying interactions between individual herbs in these formulas. Electronic databases were searched systematically, and the identified studies were collected and analyzed using Microsoft Access 2010, Graph Pad 5.0 software and Ucinet software package. 338 publications between 1997 and 2015 were identified, and analyzed in terms of annual growth and accumulated publications, top journals, forms of traditional Chinese medicine preparations and highly studied formulas and single herbs, as well as social network analysis of single herbs. There is a significant increase trend in using high-performance liquid chromatography coupled with tandem mass spectrometry related techniques in analysis of commonly used forms of traditional Chinese medicine formulas in the last 3 years. Stringent quality control is of great significance for the modernization and globalization of traditional Chinese medicine, and this bibliometric analysis provided the first and comprehensive summary within this field. © 2016 WILEY-VCH Verlag GmbH & Co.

This bibliometric review profiles the focus, dissemination, and impact of genomic nursing science articles from 2010 to 2014. Data-based genomic nursing articles by nursing authors and articles by non-nurse principal investigators funded by the National Institute of Nursing Research were categorized into the Genomic Nursing Science Blueprint nursing areas. Bibliometric content analysis was used. A total of 197 articles met the inclusion criteria. Of these, 60.3% were on biologic plausibility, 12.1% on client self-management, 11.1% on decision making or decision support, 8.1% on family, and 4.0% on communication, with the remaining 4.0% of articles focused on other topics. Few (11.6%) addressed healthcare disparities in the study purpose. Thirty-four references (17.2%) were cited 10 or more times. Research-based genomic nursing science articles are in the discovery phase of inquiry. All topics were investigated in more than one country. Healthcare disparities were addressed in few studies. Research findings from interdisciplinary teams were disseminated beyond nursing audiences, with findings addressing biologic discovery, decision making or support, and family being cited most frequently. Gaps in the reviewed articles included cross-cutting themes, ethics, and clinical utility. Interdisciplinary research is needed to document clinical and system outcomes of genomic nursing science implementation in health care. Although the review identifies areas that are encountered in clinical practice, relevance to practice will depend on evaluation of findings and subsequent development of clinical guidelines. © 2016 Sigma Theta Tau International.

SIGAPS is a bibliometric score that aims at making an inventory, evaluating and promoting scientific publications of hospitals that perform research. It has become a major stake in France since it is one of the most important components of the MERRI (Mission Training, Research, Reference and Innovation) founding of hospitals. This score is based on the points attributed to the authors of articles published in journals indexed in Medline, according to the rank of the authors and the Impact Factor of the journal. to compare the reliability of the score when applying different way of computing it, and different weights for the rank or the Impact Factor. we computed the scores of all the physicians of a University Hospital, using the rules that are actually applied at the national level. We then used 4 different scenarios, with different weight given to the rank of authors or the Impact Factor. We compared the scores obtained by each author according to the different scenarios with the Spearman's rank and Pearson's correlation coefficients. The score is not significantly affected when no points are given to the fourth authors and above, when the last author get more points or to change the points according to the Impact Factor of the journal. The different scenarios do not lead to significant changes for the physicians' scores, and therefore for the cumulated score of the hospital. Despite the well known limits of bibliometric indicators, the SIGAPS score appears reliable to compare the hospitals for founding decisions.

Molecular biology has expanded the horizons of anaesthesia during the last 20 years and has led to an increase of basic science articles that are published in the specialised anaesthetic journals or originate in anaesthetic institutions. We searched for and analysed the specific features, such as year of publication, publishing journal, and country of origin, of all such molecular biology articles stored in the MEDLINE database during the period 1986-2002. We identified 1265 original articles that used molecular biology techniques; 223 (18%) of these articles were published in anaesthetic journals and 1042 (82%) articles in 556 other biomedical journals. While in the late 1980s only a few molecular biology articles were published each year by anaesthetic institutions, worldwide this number reached approximately 200 basic science articles by the end of 2002. The USA clearly dominates the field of anaesthesia with respect to molecular biology research with 839 (66%) such articles.

This descriptive study evaluated behavioral and social science research on sport for 1993 through 2008, examined the characteristics of sport research, and identified mainstream issues appearing during these 16 years. Based on the Social Science Citation Index (SSCI) database from 1993 to 2008, 7,655 articles referring to sport or sports were available. The publication analyses showed that 13 core journals published the most articles in the behavioral sciences of sport. By analyzing all titles, author keywords, and KeyWords Plus, the results showed that physical education, athlete performance, and sports participation were the mainstream issues of sport research in the 16-year study period. The words adolescent, youth, and children frequently appeared, indicating that the emphasis of sport research focused on these participant groups. This bibliometric study reviewed global sports research in SSCI, and described certain patterns or trends in prior research on sport.

Biomedical scientific research in the Netherlands has a good reputation worldwide. Quantitatively, the university medical centres (UMCs) deliver about 40 % of the total number of scientific publications of this research. Analysis of the bibliometric output data of the UMCs shows that their research is highly cited. These output-based analyses also indicate the high impact of cardiovascular scientific research in these centres, illustrating the strength of this research in the Netherlands. A set of six joint national cardiovascular research topics selected by the UMCs can be recognised. At the top are heart failure, rhythm disorder research and atherosclerosis. National collaboration of top scientists in consortia in these three areas is successful in acquiring funding of large-scale programs. Our observations suggest that funding national consortia of experts focused on a few selected research topics may increase the international competitiveness of cardiovascular research in the Netherlands.

Parasites permeate trophic webs with their often complex life cycles, but few studies have included parasitism in food web analyses. Here we provide a highly resolved food web from the pelagic zone of a subarctic lake and explore how the incorporation of parasites alters the topology of the web. 2. Parasites used hosts at all trophic levels and increased both food-chain lengths and the total number of trophic levels. Their inclusion in the network analyses more than doubled the number of links and resulted in an increase in important food-web characteristics such as linkage density and connectance. 3. More than half of the parasite taxa were trophically transmitted, exploiting hosts at multiple trophic levels and thus increasing the degree of omnivory in the trophic web. 4. For trophically transmitted parasites, the number of parasite-host links exhibited a positive correlation with the linkage density of the host species, whereas no such relationship was seen for nontrophically transmitted parasites. Our findings suggest that the linkage density of free-living species affects their exposure to trophically transmitted parasites, which may be more likely to adopt highly connected species as hosts during the evolution of complex life cycles. 5. The study supports a prominent role for parasites in ecological networks and demonstrates that their incorporation may substantially alter considerations of food-web structure and functioning. ?? 2009 British Ecological Society.

There are increasing opportunities for nurses to engage in continuing learning via the Internet; hence, it is important to explore nurses' attitudes toward web-based continuing learning. This paper explores 267 Taiwanese clinical nurses' attitudes toward web-based continuing learning. In addition, the role of the nurses' Internet self-efficacy in their attitudes is investigated. This study utilizes two questionnaires to respectively survey the nurses' Internet self-efficacy and their attitudes toward web-based continuing learning. In particular, the Internet Self-efficacy Survey includes two scales: 'Basic self-efficacy' (the perceived confidence of using basic Internet functions, such as the confidence in using a web browser or searching for online information) and 'Advanced self-efficacy' (the perceived confidence of using advanced Internet functions, such as the confidence in online discussion or making online payments). Exploratory factor analyses indicated adequate reliability and validity of the two questionnaires. The regression analyses revealed that both nurses' basic and advanced Internet self-efficacy can positively explain the perceived usefulness, ease of use and friendly feeling when using web-based continuing learning environments, whereas nurses' advanced Internet self-efficacy was the only predictor to explain how they intend to use web-based continuing learning environments more.

OBJECTIVE To characterize the integration of phytotherapy in primary health care in Brazil. METHODS Journal articles and theses and dissertations were searched for in the following databases: SciELO, Lilacs, PubMed, Scopus, Web of Science and Theses Portal Capes, between January 1988 and March 2013. We analyzed 53 original studies on actions, programs, acceptance and use of phytotherapy and medicinal plants in the Brazilian Unified Health System. Bibliometric data, characteristics of the actions/programs, places and subjects involved and type and focus of the selected studies were analyzed. RESULTS Between 2003 and 2013, there was an increase in publications in different areas of knowledge, compared with the 1990-2002 period. The objectives and actions of programs involving the integration of phytotherapy into primary health care varied: including other treatment options, reduce costs, reviving traditional knowledge, preserving biodiversity, promoting social development and stimulating inter-sectorial actions. CONCLUSIONS Over the past 25 years, there was a small increase in scientific production on actions/programs developed in primary care. Including phytotherapy in primary care services encourages interaction between health care users and professionals. It also contributes to the socialization of scientific research and the development of a critical vision about the use of phytotherapy and plant medicine, not only on the part of professionals but also of the population.

To undertake a critical review describing key strategies supporting development of participatory research (PR) teams to engage partners for creation and translation of action-oriented knowledge. Sources are four leading PR practitioners identified via bibliometric analysis. Authors' publications were identified in January 1995-October 2009 in PubMed, Embase, ISI Web of Science and CAB databases, and books. Works were limited to those with a process description describing a research project and practitioners were first, second, third, or last author. Adapting and applying the "Reliability Tested Guidelines for Assessing Participatory Research Projects" to retained records identified five key strategies: developing advisory committees of researchers and intended research users; developing research agreements; using formal and informal group facilitation techniques; hiring co-researchers/partners from community; and ensuring frequent communication. Other less frequently mentioned strategies were also identified. This review is the first time these guidelines were used to identify key strategies supporting PR projects. They proved effective at identifying and evaluating engagement strategies as reported by completed research projects. Adapting these guidelines identified gaps where the tool was unable to assess fundamental PR elements of power dynamics, equity of resources, and member turnover. Our resulting template serves as a new tool to measure partnerships.

The goal of our study was to compile a list of the top 100 most-cited articles in stroke imaging literature across all peer-reviewed scientific journals. These articles were then analyzed to identify current trends in stroke imaging research and determine the characteristics of highly-cited articles. A database of the top 100 most-cited articles was created using Scopus and Web of Science. Articles were reviewed for applicability by 2 fellowship-trained radiologists with over 10 years of combined experience in neuroimaging. The following information was collected from each article: Article Title, Scopus Citations, Year of Publication, Journal, Journal Impact Factor, Authors, Number of Institutions, Country of Origin, Study Topic, Study Design, and Sample Size. Citations for the top 100 most-cited articles ranged from 159-810, and citations per year ranged from 5.7-516.0. Most of articles were published between 1996 and 2000 (n = 43). Articles were published across 18 journals, most commonly in Stroke (n = 40). Magnetic resonance imaging was the focus in 46 articles, computed tomogrphy in 16, and functional magnetic resonance imaging in 10. The most common study topic is prognostic use of an imaging modality (n = 27). Our study helps to characterize the field and identify the characteristics of most-cited articles.
