    Publication trends in micro-CT endodontic research: a bibliometric analysis over a 25-year period.
    U Aksoy, M Küçük, M A Versiani, K Orhan.
      AIM: To conduct a bibliographic analysis of the research studies published in Endodontics using microcomputed tomography (micro-CT) as an analytical tool over a 25-year period.METHODOLOGY: The Web of Science electronic database was accessed and an advanced search using strict criteria was undertaken from January 1995 to June 2020 for studies in the field of Endodontics that used micro-CT as an analytical tool. A further search was conducted between January and August of 2020 for a combination of specific terms and descriptors. For each selected article, the following parameters were recorded: field of the study, analysed specimen, publication title and year, authorship, journal of publication, institution and country of origin, collaborating institutions and countries, and number of citations. The acquired data were analysed using descriptive statistics and graphical mappings.
    RESULTS: The screening process identified 877 relevant articles that were classified into 30 thematic categories. The main fields of research were root canal preparation (23.8%), root canal anatomy (17.4%), canal filling (9.2%), root canal retreatment (7.0%). The most productive half-decade comprised the period of 2015-2019 (n=513; 58.5%), with the highest number of articles published in 2019 (n=146; 16.6%). The authors who lead the list as first authors were G De-Deus, A Keleş, F Paqué, MA Versiani, and Y Gu, respectively, while Versiani was the most productive (n=51). The leading countries regarding the number of studies were Brazil, China and Turkey with 236, 130 and 65 publications, respectively. The University of São Paulo (n=90; 10.3%) followed by Wuhan University (n=37; 4.2%) and the University of Zurich (n=18; 2.1%) were the prominent contributors by producing the largest number of articles, while the University of Zurich was the most cited institution. The selected studies were published in 140 scientific journals, but the Journal of Endodontics and International Endodontic Journal accounted for almost 50% of the publications.
    CONCLUSION: This bibliometric analysis portrayed an original and comprehensive view on the progress and trends of the use of micro-CT technology in endodontic research, and enabled a deep understanding of the development process in this field over the last 25 years.

    Artificial Intelligence in Various Medical Fields With Emphasis on Radiology: Statistical Evaluation of the Literature.
    Emre Pakdemirli, Urszula Wegner.
      Background Artificial intelligence (AI) has significantly impacted numerous medical specialties with high emphasis on radiology. Associated novel diagnostic methods have become a rapidly emerging hot topic, and it is essential to provide insights into quantitative analysis of the growing literature. Purpose The purpose of this study is to highlight future academic trends, identify potential research gaps, and analyze scientific landscape of AI in the field of medicine. The main aim is to explore comprehensive dataset over a 46-year period in terms of publication type, publication citation, country of origin, institution, and medical specialty. Material and Methods The Web of Science database was searched from 1975 to 2020, and publications on AI were explored. Both original research reports and review articles were included in comprehensive bibliometric analysis. Descriptive statistics were calculated, and numerous variables were applied, namely year of publication, institution, type of publication, specialty area, country of origin, and citation numbers, and the Kruskal-Wallis analysis of variance was used. Results A total of 117,974 relevant citations were retrieved, of which 83,979 original research and review articles were retained for analysis. Not surprisingly, the largest proportion of citations were from the United States (23%, n = 19,180) followed by China, Spain, England, and Germany. The number of citations was relatively consistent during the 1970s and emerging gradually during the 1980s. However, ongoing scientific trend positively evolved, and the numbers started to grow significantly in the 1990s and demonstrated continuous increasing wave since then. The most frequently represented key medical specialties were oncology, radiology, neuroradiology, and ophthalmology. Overall, no major statistical difference was found between these four domains (p = 0.753). Conclusions In summary, research on AI-powered technologies in the medical domain was at early stage in the 1970s. However, associated deep learning algorithms significantly attracted and revolutionized the scientific community with subsequent evolution of research and exponential growth of multidisciplinary publications since that time. Work in this field has impacted radiology as an area of predominant interest and has been led by institutions in the United States, Spain, France, China, and England. The bibliometric study reported herein can provide a broad overview and valuable guidance to help medical researchers gain insights into key points and trace the global trends regarding the status of AI research in medicine, particularly in radiology and other relevant multispecialty areas.

    Miguel Barboza-Palomino, Gonzalo Salas, Maribel Vega-Arce, Tomás Caycho-Rodríguez, José Ventura-León, Pablo E Flores-Kanter, Edwin Salas-Blas, Manuel Landa-Barzola, Wilson López-López.
      BACKGROUND: This study presents a bibliometric analysis of Psicothema as a commemoration for its 30 years of publishing (1989-2018).METHODS: A year-, sex-, and publication language-based analysis of the journal's characteristics was carried out based on the sample of 2,396 publications. Based on that data, Lotka's law was assessed, Lawani and Subramanyam indices and cooperation networks were estimated, the Pratt index was calculated, the concentration of papers according to thematic areas and research methods was described, and citations and impact indicators were obtained according to the original articles indexed in Web of Science (1993-2018).
    RESULTS: The results indicated greater participation by male authors, increased publication in English, compliance with Lotka's law, and a greater inter-institutional contribution in recent decades. There was a higher percentage of methodology/psychometrics-related work, and most of these publications used quantitative methods. The impact factor and the amount of citations reached its peak in 2018.
    CONCLUSION: The characteristics of Psicothema, which is a model of scientific communication of psychology in the international context, are discussed in this study.

    Turki Elarjani, Othman T Almutairi, Modhi A Alhussinan, Mohammed Bafaquh, Abdulrahman Y Alturki.
      Background: The basilar artery (BA) is one of the most critical vessels that supply blood to the brain stem, cerebellum, and parts of the cerebral hemispheres. Many studies on the BA from neurobiological, clinical, and experimental perspectives exist. This bibliometric study was aimed at identifying the most-cited articles related to the BA in different disciplines.Methods: A title-specific search was carried out using the Scopus database, and the top 100 most-cited articles were collected and analyzed. Article- and cytometric-based parameters were established for the literature review.
    Results: The top 100 articles have an accumulative citation count of 13,595, with an average of 135.95 citations per paper. The publication dates range from 1946 to 2015, with the most productive years being those in the 1990s. Experimental studies are the most frequent category, followed by endovascular ones. The top-cited article has received a total of 435 citations, with 18.12 citations per year. The United States of America has contributed the most to the top 100 cited articles. The lead research institution was the University of Bern, and the most contributing journal was the Journal of Neurosurgery.
    Conclusion: A bibliometric analysis of BA researches revealed landmark papers and trends over the years, such as on the introduction of endovascular management in basilar aneurysm and occlusion. The highly cited articles in multi-disciplinary areas related to the BA may help develop future novel ideas for research in the laboratory and translational fields.

    Michele Lastella, Aamir Raoof Memon, Grace E Vincent.
      This study examined sleep research in athletes published between 1966 and 2019, through a bibliometric analysis of research output in the Scopus database. Following a robust assessment of titles, the bibliometric indicators of productivity for studies included in the final analysis were: Distribution of publications and citations (excluding self-citations), top ten active journals, countries, institutions and authors, single- and multi-country collaboration, and 25 top-cited papers. Out of the 1015 papers, 313 were included in the final analysis. The majority of the papers were research articles (n = 259; 82.8%) and published in English (n = 295; 94.3%). From 2011, there was a dramatic increase in papers published (n = 257; 82.1%) and citations (n = 3538; 91.0%). The number of collaborations increased after 2001, with papers published through international (n = 81; 25.9%) and national (n = 192; 61.3%) collaboration. Australia was the most prolific country in terms of number of publications (n = 97; 31.0%), and citations (n = 1529; 15.8%). In conclusion, after the beginning of the twenty-first century, the scientific production on sleep research in athletes has seen significant growth in publication and citation output. Future research should focus on interventions to improve sleep in athletes.

    Bibliometric and Visualization Analysis of Human Coronaviruses: Prospects and Implications for COVID-19 Research.
    Ziqin Deng, Junsheng Chen, Ting Wang.
      Human coronaviruses, which can cause a range of infectious diseases, have been studied for nearly 60 years. The field has gained renewed interest from researchers around the world due to the COVID-19 outbreak in late 2019. Despite a large amount of research, little is known about the knowledge structure and developing trends of this topic. Here, we apply bibliometric analysis along with visualization tools to analyze 15,207 publications related to human coronavirus from the Scopus database, using indicators on publication and citation, journal, country or territory, affiliation and international cooperation, author, and keyword co-occurrence cluster. The results show that research on human coronavirus is dominated by SARS-CoV. Although there have been many publications, only 626 publications (4.1% of total) have more than 100 citations. The top 20 journals with most publications account for 20.6% of total publications and 41% of total citations. In addition to the United States and some European countries, many Asian and African countries are involved in this research, with China holding an important position in this area. Leading researchers from various fields of human coronavirus research are listed to facilitate collaboration and promote effective disease prevention and control. The keywords co-occurrence analysis reveals that the research focus on virology, public health, drugs and other hotspot fields, and uncovers changes in the direction of coronavirus research. The research map on human coronavirus obtained by our analysis are expected to help researchers to efficiently and effectively explore COVID-19.

    Trending Literature in Spinal Tuberculosis: Bibliographic Analysis of Top 250 Cited Articles.
    Muthu Sathish, Ramakrishnan Eswar.
      BACKGROUND: This bibliographic analysis aims to identify the top 250 cited articles on spinal tuberculosis (TB) and report on their impact on the spinal field.METHODS: All databases included in the Thomson Reuters Web of Science were searched for publications on spinal TB. The most cited articles published between 1950 and 2019, with the main focus on orthopaedic surgery, were identified using a multistep approach, and a total of 250 articles were included and analyzed for title, year of publication, total citations, citations in 2019, citation density, article age, journal, first author, senior author, geographic origin, and level of evidence.
    RESULTS: The number of citations ranged from 31 to 257, with an average of 65.38. Studies were published from 31 different countries and published in 83 different journals. The top 3 countries, India, United States, and China published a total of 57.8% (n = 145) of all articles. Indian and Chinese researchers seem to be the most resourceful, as 17 of the 31 (54.8%) prospective studies were conducted by them. African centers produced only 3.2% (n = 8) of all included articles. Only 3.2% (n = 8) were of Level 1 evidence on the subject. A total of 37.8% (n = 95) were on diagnosis, while 46.6% (n = 117) dealt with surgery, and only 15.1% (n = 38) were about conservative management. Anil K Jain followed by S Rajasekaran were the most published authors on the subject.
    CONCLUSIONS: Indian and Chinese researchers dominate evidence in spinal TB. Regions with high disease burden, such as Africa, do not contribute their data to the literature. Though these are the top cited articles in the subject, their level of evidence needs improvement for better impact of their results.

    Publications in Integrative and Complementary Medicine: A Ten-Year Bibliometric Survey in the Field of ICM.
    Zuoqi Ding, Furong Li.
      Background: This article aims to analyze the research status of integrative complementary medicine (ICM) and features of highly cited papers in the field to provide reference of the future development of ICM.Methods: Publications in the field of ICM from 2009 to 2018 were retrieved from the Web of Science Core Collection. The top 20 countries/territories, institutions, journals, keywords of highly cited and noncited papers, and characteristics of essential science indicator (ESI) papers, as well as open access (OA) and non-OA papers, were analyzed.
    Results: Mainland China had the largest number of ICM publications. The top 20 journals published a total of 31667 papers in 2009-2018, which represented 92.9% of all publications. Keywords of highly cited and noncited papers point to different research directions. 48 ESI highly cited/hot papers were identified, most of which are related to phytochemistry. Furthermore, the average citation rate (percentage of publications that have been cited one or more times) of OA papers was lower than that of total papers and non-OA papers.
    Conclusions: China leads in number of publications; however, publication quality in ICM field requires improvement. A few journals accounted for more than half of number of publications and citations, which are important for the development of ICM. Many of the keywords in ICM noncited publications pointed towards broad meaning that poorly reflect the exact research content. Most highly cited ICM studies focused on the identification and evaluation of plant active components. OA may not be an effective approach to increase paper citations in the field of ICM.

    Research Trends and Hotspot Analysis of Conjunctival Bacteria Based on CiteSpace Software.
    Zhenyu Wang, Chen Huang, Xuemin Li.
      Objective: To sort out the literature related to conjunctival bacteria and summarize research hotspots and trends of this field.Materials and Methods: The relevant literature data from 1900 to 2019 was retrieved from the Web of Science Core Collection database. After manual selection, each document record includes title, author, keywords, abstract, year, organization, and citation. We imported the downloaded data into CiteSpace V (version 5.5R2) to draw the knowledge map and conduct cooperative network analysis, discipline and journal analysis, cluster analysis, and burst keyword analysis.
    Results: After manual screening, there were 285 relevant papers published in the last 28 years (from 1991 to 2019), and the number is increasing year by year. The publications of conjunctival bacteria were dedicated by 1381 authors of 451 institutions in 56 countries/regions. The United States dominates this field (82 literatures), followed by Germany (23 literatures) and Japan (23 literatures). Overall, most cited papers were published with a focus on molecular biology, genetics, nursing, and toxicology. Most papers fall into the category of ophthalmology, veterinary sciences, and pharmacology and pharmacy. The only organized cluster is the "postantibiotic effect," and the top 5 keywords with the strongest citation bursts include "postoperative endophthalmiti(s)," "infectious keratoconjunctiviti(s)," "conjunctiviti(s)," "resistance," and "diversity".
    Conclusion: The global field of conjunctival bacteria has expanded in the last 28 years. The United States contributes most. However, there are little cooperation among authors and institutions. Overall, this bibliometric study organized one cluster, "postantibiotic effect", and identified the top 5 hotspots in conjunctival bacteria research: "postoperative endophthalmiti(s)," "infectious keratoconjunctiviti(s)," "conjunctiviti(s)," "resistance," and "diversity". Thus, further research focuses on these topics that may be more helpful to prevent ocular infection and improve prophylaxis strategies to bring a benefit to patients in the near future.

    The state of nursing research from 2000 to 2019: A global analysis.
    Su Yanbing, Liu Hua, Liu Chao, Wang Fenglan, Duan Zhiguang.
      AIM: This study aims to present a general bibliometric overview of the development status of global nursing research from 2000 to 2019.DESIGN: A longitudinal bibliometric analysis of nursing research was conducted.
    METHODS: Nursing research publications (N = 88,665) were obtained from Web of Science. Bibliometric method was used to map the output and citation impact trends of countries/regions, institutions, disciplines, and journals and analyse the research collaboration among countries/regions and institutions.
    RESULTS: The global paper output in nursing research increased steadily over the past two decades and it varied in different countries/regions with the USA being far ahead of the others. The paper output and cross-border collaboration are mainly distributed in several developed countries like the USA, the UK, Australia, and Canada. The University of Pennsylvania, Harvard University, University of Toronto, and University of North Carolina at Chapel Hill have high academic influence in the field of nursing. Increasing attention from academic fields has been paid to research on nursing. Journal of Advanced Nursing is the most prolific and most cited journal in nursing field.
    CONCLUSION: Nursing research has developed steadily over the last two decades. Both the scientific output and research collaboration are disproportionally distributed between high-income countries/regions and low- and middle-income countries/regions. Most research and collaboration have taken place in a few developed countries across North America, Europe, and Oceania.
    IMPACT: The study highlighted the need for policy makers and funding agencies, especially those from low- and middle-income countries/regions, to allocate research funding that supports the nursing higher education and international cooperation so as to promote the development of high-quality nursing research in those countries/regions. At the same time, researchers from non-English-speaking countries/regions should attach more importance to publishing papers in English, strengthening the academic exchanges with international nursing colleagues and better integrating into the international academic community.

      PURPOSE: This bibliometric analysis maps the landscape of knowledge syntheses in medical education. It provides scholars with a roadmap for understanding where the field has been and where it might go in the future, thereby informing research and educational practice. In particular, this analysis details the venues in which knowledge syntheses are published, the types of syntheses conducted, citation rates they produce, and altmetric attention they garner.METHOD: In 2020, the authors conducted a bibliometric analysis of knowledge syntheses published in 14 core medical education journals from 1999 to 2019. To characterize the studies, metadata were extracted from PubMed, Web of Science, Altmetrics Explorer, and Unpaywall.
    RESULTS: The authors analyzed 963 knowledge syntheses representing 3.1% of the total articles published (n = 30,597). On average, 45.9 knowledge syntheses were published annually (SD = 35.85, median = 33), and there was an overall 2620% increase in the number of knowledge syntheses published from 1999 to 2019. The journals each published, on average, a total of 68.8 knowledge syntheses (SD = 67.2, median = 41) with Medical Education publishing the most (n = 189; 19%). Twenty-one types of knowledge synthesis were identified, the most prevalent being systematic reviews (n = 341; 35.4%) and scoping reviews (n = 88; 9.1%). Knowledge syntheses were cited an average of 53.80 times (SD = 107.12, median = 19) and received a mean Altmetric Attention Score of 14.12 (SD = 37.59, median = 6).
    CONCLUSIONS: There has been considerable growth in knowledge syntheses in medical education over the past 20 years, contributing to medical education's evidence base. Beyond this increase in volume, researchers have introduced methodological diversity in these publications, and the community has taken to social media to share knowledge syntheses. Implications for the field, including the impact of synthesis types and their relationship to knowledge translation, are discussed.

    Contribution of Pathologists in Leading Clinical Cancer Research Through Interdisciplinary Collaboration in Saudi Arabia.
    Moataz Muwar, Alaa Samkari, Majed Alghamdi.
      Background Interdisciplinary collaboration is often the key to advance cancer research. This research collaboration is frequently observed between oncologists and pathologists. While clinical cancer research is often led by oncologists, the leading role of pathologists is likely limited to laboratory-based and preclinical research. Therefore, the magnitude and characteristics of clinical studies led by pathologists is largely unknown. Objectives The objective of our study was to assess the quantity and quality of clinical cancer-related publications led by Saudi pathologists over a 10-year period. Methods A PubMed search was conducted between January 2008 and December 2017 to extract all published clinical articles regarding cancer by at least one Saudi pathologist with the collaboration of other cancer specialists. Information about articles and authors were collected. The level of evidence (LOE) was independently assessed by two authors. Two five-year periods (2008 - 2012 and 2013 - 2017) were compared using the relevant parameters. Results A total of 127 publications met our inclusion criteria and were included. Review articles (27%) were the most common type of publication. There were no experimental studies. The LOE was III and IV in 59.1% and 40.9% of the included publications, respectively. Comparing the two five-year periods, the number of publications (p < 0.001), publications in international journals (p = 0.004), and international collaborations (p < 0.001) increased in the second period. The LOE and journal impact factor were the same in the two periods. Conclusions The pathologist-led clinical cancer research in Saudi Arabia increased over time. Despite the observed increase in international collaboration and publications in international journals, the LOE was low (III/IV) and did not change over time.

    Cross-sectional analysis of bibliometrics and altmetrics: comparing the impact of qualitative and quantitative articles in the British Medical Journal.
    Helene Retrouvey, Fiona Webster, Toni Zhong, Anna R Gagliardi, Nancy N Baxter.
      OBJECTIVES: In comparison to quantitative research, the impact of qualitative articles in the medical literature has been questioned by the BMJ; to explore this, we compared the impact of quantitative and qualitative articles published in BMJ.DESIGN: Cross-sectional survey.
    SETTING: Articles published in the BMJ between 2007 and 2017.
    MAIN OUTCOME MEASURES: Bibliometric and altmetric measures of research impact were collected using Web of Science, Google Scholar, Scopus, Plum Analytics and ProQuest Altmetric. Bibliometric measures consisted of citation numbers, field weighted citation impact and citation percentile. Altmetric measures consisted of article usage, captures, mentions, readers, altmetric attention score and score percentile. Scores were compared using the Wilcoxon Rank-sum test.
    RESULTS: We screened a total of 7777 articles and identified 42 qualitative articles. Each qualitative article was matched to 3 quantitative articles published during the same year (126 quantitative articles). Citation numbers were not statistically different between the two research types; the median number of citations (google scholar) per quantitative article was 62 (IQR 38-111) versus 58 (IQR 36-85) per qualitative article (p=0.47). Using Plum Analytics, qualitative articles were found to have a significantly higher usage, with a median of 984 (IQR 581-1351) versus 379 (IQR 177-763) for quantitative (p<0.001). The Altmetric Attention Score was higher for quantitative articles at 16 (IQR 7-37) versus qualitative articles at 9 (IQR 5-23, p=0.05), as was the Altmetric Score percentile 93 (IQR 87-96) versus 88 (IQR 76-95; p=0.02).
    CONCLUSION: Qualitative and quantitative articles published in the BMJ between 2007 and 2017 both have a high impact. No article type was consistently superior in terms of bibliometric or altmetric measures, suggesting that type of article is not the major driver of impact.

    Speaking across boundaries to explore the potential for interdisciplinarity in ecosystem services knowledge production.
    Marleen S Schutter, Christina C Hicks.
      Conservation is likely to be most successful if it draws on knowledge from across the natural and social sciences. The ecosystem services concept has been termed a boundary object, facilitating the development of such interdisciplinary knowledge through a common platform for researchers, policy makers, and practitioners. However, critique of the concept has focused on narrow disciplinary framings that counteract its original interdisciplinary aspirations. A question that remains is to what extent these critiques are reflected in a (lack of) disciplinary diversity within the field. Here, we ask 1) where is knowledge on ecosystem services produced? 2) how interdisciplinary is this knowledge? And, 3) which disciplines facilitate the greatest disciplinary integration? We define interdisciplinarity as the extent to which published research draws on knowledge that crosses disciplinary borders, and use citations as a quantitative indicator of communication among disciplines- based on journal classification. We use diversity, richness, and hetero-citation as measures of interdisciplinarity, and betweenness centrality for disciplinary integration. We find that the field of ecosystem services research has matured and grown to publish more articles, across more disciplines, in an increasingly dense network of citations; however, this growth has not been mirrored by an increase in the diversity or richness of citation patterns. Hetero-citation scores, or out-of-group citations, for Arts, Humanities, Social Sciences and Law (AHSSL) are lower than would be expected, although they are beginning to bridge the gap with Science, Technology, Engineering and Mathematics (STEM). Ultimately, a small number of productive disciplines are central to supporting disciplinary integration. However, opportunities exist for conservation practice to draw on a broader field of research, to realise the potential that the diverse body of knowledge of interdisciplinary work offers. Impact statement: Ecosystem services holds promise in conservation settings, but STEM disciplines dominate, despite increased involvement of AHSSL disciplines. This article is protected by copyright.

    Citations Network Analysis of Vision and Sport.
    Henrique Nascimento, Clara Martinez-Perez, Cristina Alvarez-Peregrina, Miguel Ángel Sánchez-Tena.
      Background: Sports vision is a relatively new specialty, which has attracted particular interest in recent years from trainers and athletes, who are looking at ways of improving their visual skills to attain better performance on the field of play. The objective of this study was to use citation networks to analyze the relationships between the different publications and authors, as well as to identify the different areas of research and determine the most cited publication. Methods: The search for publications was carried out in the Web of Science database, using the terms "sport", "vision", and "eye" for the period between 1911 and August 2020. The publication analysis was performed using the Citation Network Explorer and CiteSpace software. Results: In total, 635 publications and 801 citations were found across the network, with 2019 being the year with the highest number of publications. The most cited publication was published in 2002 by Williams et al. By using the clustering functionality, four groups covering the different research areas in this field were found: ocular lesion, visual training methods and efficiency, visual fixation training, and concussions. Conclusions: The citation network offers an objective and comprehensive analysis of the main papers on sports vision.

    Gender (Im)balance in Citation Practices in Cognitive Neuroscience.
    Jacqueline M Fulvio, Ileri Akinnola, Bradley R Postle.
      In the field of neuroscience, despite the fact that the proportion of peer-reviewed publications authored by women has increased in recent decades, the proportion of citations of women-led publications has not seen a commensurate increase: In five broad-scope journals, citations of articles first- and/or last-authored by women have been shown to be fewer than would be expected if gender was not a factor in citation decisions [Dworkin, J. D., Linn, K. A., Teich, E. G., Zurn, P., Shinohara, R. T., & Bassett, D. S. The extent and drivers of gender imbalance in neuroscience reference lists. Nature Neuroscience, 23, 918-926, 2020]. Given the important implications that such underrepresentation may have on the careers of women researchers, it is important to determine whether this same trend is true in subdisciplines of the field, where interventions might be more targeted. Here, we report the results of an extension of the analyses carried out by Dworkin et al. (2020) to citation patterns in the Journal of Cognitive Neuroscience. The results indicate that the underrepresentation of women-led publications in reference sections is also characteristic of articles published in Journal of Cognitive Neuroscience over the past decade. Furthermore, this pattern of citation imbalances is present regardless of author gender, implicating systemic factors. These results contribute to the growing body of evidence that intentional action is needed to address inequities in the way that we carry out and communicate our science.

    Medical thesis publication and academic productivity of pediatric residents at the Medical University of Marseille: Associated factors and evolution over 20 years.
    I Brunod, N Rességuier, A Fabre.
      BACKGROUND: In many countries, as in France, medical training is not complete until the defense of a thesis, based on a research project; however, the publication of research work is not mandatory. This study investigated the evolution of the publication pattern of pediatric residents and identified the possible factors associated with an increased productivity, by investigating both thesis and non-thesis-related publications.MATERIALS AND METHODS: We conducted a retrospective cohort study of pediatric residents who graduated from the Medical University of Marseille in France over a 20-year period (1996-2015). Their theses were retrieved from the French database of university theses (SUDOC). Their publications were collated by scanning the PubMed and Google Scholar databases. Non-thesis-related publications were included up to 1 year after the medical thesis defense and medical thesis publications were included without date limits. For each thesis or publication, the resident's characteristics, the supervisor's characteristics, the thesis characteristics, and bibliometric features were retrieved.
    RESULTS: Out of the 148 graduated residents, 110 (74%) published articles (thesis-related article with no publication deadline and non-thesis-related articles with a publication deadline of up to 1 year postgraduation): 76 residents (51%) published their medical thesis and 88 residents (60%) published at least one non-thesis-related article. In multivariate analysis, publishing the thesis was significantly associated with a shorter dissertation length (43 vs. 84 pages [median]; p=0.009**) and with a thesis supervisor more experienced in supervising theses (P=0.01**). The thesis publication rate increased significantly over the years (P=0.005**), with the number of theses published tripling. Dissertation length significantly decreased over the years (linear slope=-4.13 pages/year; P<0.0001***). In multivariate analysis, the number of publications per resident was significantly higher when the resident had also completed a scientific thesis (β=1.62; P=0.007**), when he or she had published more papers during the post-residency period (β=0.40; P<0.0001***) and when he or she graduated at an older age (β=0.24; P=0.04*).
    CONCLUSION: The thesis publication rate of pediatric residents has improved significantly in 20 years; however, these results are from a single-center study. Publishing the thesis was significantly associated with shorter dissertation length and a more experienced thesis supervisor.

    Adherence to the Strengthening the Reporting of Observational Studies in Epidemiology Statement in Observational Studies Published in Iranian Medical Journals.
    Soheila Shaghaghian, Behrooz Astaneh.
      Background: Although much medical knowledge comes from observational research, such studies are more prone to confounding and bias than others. This study was conducted to evaluate the adherence of the observational studies published in Iranian medical journals to the STROBE (strengthening the reporting of observational studies in epidemiology) statement.Methods: In this cross-sectional study, we selected 150 articles of Iranian medical journals, using multistage sampling from Aug 2016 to Jun 2017. The reported items of the STROBE statement in the articles was determined and considered as the adherence of the articles to the statement. The adherence of the articles with different characteristics was compared.
    Results: The adherence of the articles to the statement varied from 24% to 68% with a mean score of 48%±9%. The lowest mean scores were found in the Result (36%) and Method (49%) sections. The adherence was significantly better in the articles published in the journals indexed in PubMed or Web of Knowledge (ISI) databases (P<0.001) and those written by cooperation of the authors from other countries (P=0.044).
    Conclusion: The evaluated articles in our study had not adequately reported the items recommended by the STROBE statement. This indicates deficiency in key elements for readers to assess the validity and applicability of a study.

    Will the increase in publication volumes "dilute" prestigious journals' impact factors? A trend analysis of the FT50 journals.
    Tenghao Zhang.
      In the wake of the unprecedented global scientific output boom, are top-tier journals such as the FT50 journals following suit? If these prestigious journals consistently increase their publication volumes, will their impact factors be affected? Drawing on the Mann-Kendall trend test method, this study analysed time series trends of the FT50 journals' annual publication volumes and impact factor ratios (IFR) over a 15 year period. The results indicate that half of the FT50 journals have consistently increased their publication volumes over the years. Although to increase publication volumes is riskier than to stay put, it has a significantly higher probability of increasing the IFR, and therefore keeping pace with other top journals. However, the expanding of publication volumes must be carried out cautiously, as the study also finds that growing too fast may lead to opposite effects.

    Gender representation in pediatric ophthalmology: an analysis of trends over a decade.
    Meghana Kalavar, Arjun Watane, Marissa M Patel, Jayanth Sridhar, Kara M Cavuoto.
      PURPOSE: To assess trends in gender representation in pediatric ophthalmology.METHODS: In this retrospective study, the names of oral and poster presenters at the American Association for Pediatric Ophthalmology and Strabismus (AAPOS) annual meetings and the first and last authors of articles published in Journal of AAPOS (J AAPOS) from 2011 to 2019 were recorded. The gender of presenters and authors was determined with the aid of an online gender tool in conjunction with a comprehensive internet search.
    RESULTS: A total of 2,633 presentations, and 2,777 authors were included. Over the study period, female representation in both conferences and journal authorship increased (P > 0.01 and P = 0.01 resp.). Overall, women comprised 44% of oral presentations and 57% of poster presentations at the annual meetings. Of publications in J AAPOS, women comprised 47% of first authors and 38% of last authors. The gender of the first author did not correlate with the gender of the last author (P = 0.9). Conference roles that had the greatest gender disparities were named lecture speakers (27% female vs 73% male [P = 0.01]) and program committee members (34% female vs 66% male [P > 0.01]).
    CONCLUSIONS: Over the last decade, there has been an increase in representation of women at both AAPOS conferences and authorship in J AAPOS. Gender disparities persist in higher-visibility positions.

    Publishing Characteristics of Foot and Ankle Research Over a 15-Year Time Interval: A Review of The Journal of Bone & Joint Surgery from 2004 to 2018.
    Bradley K Alexander, James W Hicks, Abhinav Agarwal, Benjamin B Cage, Spaulding F Solar, Aaradhana J Jha, Gerald McGwin, Ashish Shah.
      BACKGROUND: As the foot and ankle subspecialty continues to grow in orthopaedics, trends in published literature provide valuable insights to help understand and strengthen the field. The current study evaluates the changes in the characteristics of foot and ankle articles in The Journal of Bone & Joint Surgery (American Volume) (JBJS-A) from 2004 to 2018.METHODS: Foot and ankle-related articles in JBJS-A from 2004 to 2018 were identified and categorized by type of study, level of evidence, number of authors, academic degree(s) of the first and last authors, male and female authorship, number of citations, number of references, region of publication, and use of patient-reported outcomes (PROs).
    RESULTS: A total of 336 foot and ankle articles from 2004 to 2018 were reviewed. The type of study published has changed over time, with more clinical therapeutic evidence and less case reports. The level of evidence grades, as rated by JBJS-A and objective evaluators, have increased over the past 15 years. The total number of authors per article has increased, and female authorship has increased significantly. The number of references per article has increased, and the number of citations per year has decreased. The field of foot and ankle surgery has seen an increase in global publications.
    CONCLUSIONS: The results of this study suggest that the foot and ankle literature that has been published in JBJS-A has continued to increase in quality and diversity over the past 15 years.

    Clara Martinez-Perez, Cristina Alvarez-Peregrina, Cesar Villa-Collar, Miguel Ángel Sánchez-Tena.
      BACKGROUND: The first outbreaks of the new coronavirus disease, named COVID-19, occurred at the end of December 2019. This disease spread quickly around the world, with the United States, Brazil and Mexico being the countries the most severely affected. This study aims to analyze the relationship between different publications and their authors through citation networks, as well as to identify the research areas and determine which publication has been the most cited.METHODS: The search for publications was carried out through the Web of Science database using terms such as "COVID-19" and "SARS-CoV-2" for the period between January and July 2020. The Citation Network Explorer software was used for publication analysis.
    RESULTS: A total of 14,335 publications were found with 42,374 citations generated in the network, with June being the month with the largest number of publications. The most cited publication was "Clinical Characteristics of Coronavirus Disease 2019 in China" by Guan et al., published in April 2020. Nine groups comprising different research areas in this field, including clinical course, psychology, treatment and epidemiology, were found using the clustering functionality.
    CONCLUSIONS: The citation network offers an objective and comprehensive analysis of the main papers on COVID-19 and SARS-CoV-2.

    Publishing trends in the field of urgent care medicine from 2000 to 2020: A bibliometric analysis.
    Lauren A McNickle, Kevin C Chiang, Elise M McNulty, Robert P Olympia.
      BACKGROUND: With a steady rise in the number of urgent care centers in the United States and the establishment of urgent care medicine as a specialty, research in the field is likely to emerge.OBJECTIVES: To perform a bibliometric analysis of published studies in the field of urgent care medicine over the past two decades.
    METHODS: A comprehensive literature review was conducted, including original and review articles pertaining to urgent care medicine published 2000-2020. Data abstracted from each article included publication year, journal, research study design, study population, clinical relevance (clinical or non-clinical), and study topics.
    RESULTS: A total of 144 publications from 94 peer-reviewed journals were analyzed. There has been a steady increase in the annual number of publications from 2010 to 2019. The most common study designs were retrospective (55.5%), study specific (24.3%), prospective (15.3%), and quality improvement (4.9%). Adults were the most frequently identified study population (33.3%), followed by pediatrics (18%), and both adults and pediatrics (16.7%). Publications were categorized as clinical (48.6%) and non-clinical (51.4%). The most common research topics were urgent care utilization [n = 34, 23.6%; especially effectiveness (n = 9) and disease based (n = 7)], diagnostic testing [(n = 20, 13.9%; especially HIV (n = 7) and sexually transmitted infections (n = 6)], and antibiotic stewardship (n = 17, 11.8%).
    CONCLUSION: Based on our sample, published research in the field of urgent care medicine has evolved. By describing current trends, we hope that clinicians and researchers continue to advance the field by developing high quality research, including prospective, multi-institutional/center studies involving both clinical and non-clinical topics.

    Citations of Murray Sidman's work in JEAB: Evidence of a long and large contribution.
    Anita Li, Hugo Curiel, Alan Poling.
      We examined citations of Murray Sidman's publications in the Journal of the Experimental Analysis of Behavior from the journal's inception in 1958 through May 2020. On average, he was cited 35.6 times per year. The rate of citation did not change substantially across time and the cumulative citation count was 2,212. His 10 publications cited most often deal with behavior-analytic research methods, stimulus equivalence, and unsignaled free-operant (or Sidman) avoidance. Our data provide clear evidence of the breadth and depth of Sidman's influence on the experimental analysis of behavior across 7 decades. His contributions were both exceptional and praiseworthy and his legacy will long endure.

    Publishing in English is associated with an increase of the impact factor of Brazilian biodiversity journals.
    Juan C S Abad, Raony M Alencar, Ben H Marimon, Beatriz Marimon, Adelmo C C Silva, Halina Jancoski, Renan S Rezende, EstevÃo Alves-Silva.
      English is the lingua franca for scientific communication, but some journals, especially in developing countries, still publish non-English studies. A shift towards publishing in English may promote internationalization and more visibility of scientific journals. Here we compared quality indexes between Brazilian journals that have always published in English and journals that have published in languages other than English. We also investigated whether a temporal shift towards publishing in English led to elevated quality measures. Our analyses covered 16 Brazilian biodiversity journals and accounted for 12640 papers published since 2007. The mean impact factor was on average 55% higher in journals that have published consistently in English, compared to the so-called multilanguage journals. The proportion of publications in English increased to nearly three times the original value in multilanguage journals between 2007 and 2016, and the impact factor tripled during this period. At the same time, the Qualis-Capes classifications (B1-B2-B3) tended to fall. Publishing in English can be a first step to increased visibility, and this is particularly important for biodiversity journals, since Brazilian ecosystems are considered of interest to the international scientific community and nature conservation.

    Measuring the quality of scientific references in Wikipedia: an analysis of more than 115M citations to over 800,000 scientific articles.
    Joshua M Nicholson, Ashish Uppala, Matthias Sieber, Peter Grabitz, Milo Mordaunt, Sean C Rife.
      Wikipedia is a widely used online reference work which cites hundreds of thousands of scientific articles across its entries. The quality of these citations has not been previously measured, and such measurements have a bearing on the reliability and quality of the scientific portions of this reference work. Using a novel technique, a massive database of qualitatively described citations, and machine learning algorithms, we analyzed 1,923,575 Wikipedia articles which cited a total of 824,298 scientific articles in our database, and found that most scientific articles cited by Wikipedia articles are uncited or untested by subsequent studies, and the remainder show a wide variability in contradicting or supporting evidence. Additionally, we analyzed 51,804,643 scientific articles from journals indexed in the Web of Science and found that similarly most were uncited or untested by subsequent studies, while the remainder show a wide variability in contradicting or supporting evidence.

    Trends of women's authorship in an Iranian medical journal from 1999 to 2019.
    Amrollah Shamsi, Emad Behboudi, Mostafa Barghi, Hadiseh Heidari.
      Author's gender is a potential factor in scientific publications. We evaluated the trends of authorship gender by focusing on women in an Iranian medical journal and followed two aims: A) Mapping gender trends in authorship positions; B) Drawing the patterns among authors. Our results showed that between 1999 and 2019, the role of women as first author was 26.7% and 54.9% (p < 0.05); as last authors 33.3% and 37.3% and as corresponding author 23.3% and 36.7%, respectively. Despite progresses made by women, they were not significantly successful as corresponding and last authors. Further researchers around the world can have similar focus and be useful in making decisions for equality issues.

      This study quantitatively investigated the scientific progress of walkability research landscape and its future prospects using bibliometric indicators to highlight the research hotspots. The results accentuated multifaceted nature of walkability research landscape with a strong association towards public health disciplines. Keyword co-occurrence analysis emphasized that majority of the walkability studies centred on the interactions between walking and other three main factors such as built environment attributes, transportation and obesity. Based on the identified research hotspots, a brief state-of-the-art review of walkability studies was presented. Future prospects based on the unexplored research gaps within the hotspots were also discussed. High correlation (r = 0.99, p < 0.05) between annual publications and citation counts demonstrated the significance of walkability studies to the contemporary scientific community. Being one of the comprehensive studies to evaluate the historic trajectory of walkability research landscape, the findings were expected to accelerate a comprehensive understanding of the walkability research domain that will assist future research direction.

    International collaboration in Brazilian science: financing and impact.
    Concepta McManus, Abilio Afonso Baeta Neves, Andrea Queiroz Maranhão, Antonio Gomes Souza Filho, Jaime Martins Santana.
      The study of international collaborations can help in understanding the benefits of such relationships and aid in developing national financing policies. In this paper, the international collaboration of Brazilian scientists was studied using SciVal® and Incites® database, looking at its effect on the universities, financing agencies and different areas of knowledge and research topic clusters. Cluster and principal component analyses of scientometric data were carried out. While the results confirmed known knowledge that international collaboration increases impact, this study shows that Brazilian researchers are contributing to prominent research topics worldwide, in all areas of knowledge. This finding is contrary to several points of view that identify Brazil as a regional and not an international partner in science. Important also to note the impact of Brazilian authors in international collaboration that is well above the world mean. The collaboration of Brazil with foreign partners brings benefits for both sides, creating the opportunity of Brazilian research access to financing from international agencies. Increases in measures of impact are also seen for both sides. Foreign partners likewise benefit from higher impact factors in the same topic cluster, when collaborating with Brazilian partners. Publishing open access in high impact journals is fundamental for maintaining Brazilian science at the forefront.

    Characteristics of Heart Failure Trials Associated With Under-Representation of Women as Lead Authors.
    Sera Whitelaw, Lehana Thabane, Mamas A Mamas, Nosheen Reza, Khadijah Breathett, Pamela S Douglas, Harriette G C Van Spall.
      BACKGROUND: Clinical trials change practice in cardiology, and leading them requires research training, mentorship, sponsorship, and networking. Women report challenges in obtaining these opportunities.OBJECTIVES: The purpose of this review was to evaluate temporal trends in representation of women as authors in heart failure (HF) randomized controlled trials (RCTs) published in high-impact medical journals and explore RCT characteristics associated with women as lead authors.
    METHODS: We searched MEDLINE, EMBASE, and CINAHL for HF RCTs published in journals with an impact factor ≥10 between January 1, 2000, and May 7, 2019. We assessed temporal trends in the gender distribution of authors, and used multivariable logistic regression to determine characteristics associated with women as lead authors.
    RESULTS: We identified 10,596 unique articles, of which 403 RCTs met inclusion criteria. Women represented 15.6% (95% confidence interval [CI]: 12.2% to 19.6%), 12.9% (95% CI: 9.8% to 16.6%), and 11.4% (95% CI: 8.5% to 14.9%) of lead, senior, and corresponding authors, respectively. The proportion of women authors has not changed over time. Women had lower odds of lead authorship in RCTs that were multicenter (odds ratio [OR]: 0.58; 95% CI: 0.18 to 0.96; p = 0.037), were coordinated in North America (OR: 0.21; 95% CI: 0.08 to 0.70; p = 0.011) or Europe (OR: 0.33; 95% CI: 0.09 to 0.91; p = 0.039), tested drug interventions (OR: 0.42; 95% CI: 0.16 to 0.97; p = 0.043), or had men as the senior author (OR: 0.50; 95% CI: 0.21 to 0.93; p = 0.043).
    CONCLUSIONS: Women are under-represented as authors of HF RCTs, with no change in temporal trends. Women had lower odds of lead authorship in RCTs that were multicenter, were coordinated in North America or Europe, tested drug interventions, or had men as senior authors.

    Multilayer network approach to modeling authorship influence on citation dynamics in physics journals.
    Vahan Nanumyan, Christoph Gote, Frank Schweitzer.
      We provide a general framework to model the growth of networks consisting of different coupled layers. Our aim is to estimate the impact of one such layer on the dynamics of the others. As an application, we study a scientometric network, where one layer consists of publications as nodes and citations as links, whereas the second layer represents the authors. This allows us to address the question of how characteristics of authors, such as their number of publications or number of previous coauthors, impacts the citation dynamics of a new publication. To test different hypotheses about this impact, our model combines citation constituents and social constituents in different ways. We then evaluate their performance in reproducing the citation dynamics in nine different physics journals. For this, we develop a general method for statistical parameter estimation and model selection that is applicable to growing multilayer networks. It takes both the parameter errors and the model complexity into account and is computationally efficient and scalable to large networks.

    Publication Trends in Pediatric Dentistry Journal: A 20-year Bibliometric Analysis (1999-2018).
    Lisa Ohta, Brigitte O'Brien, Hannah Knight, Jilen Patel, Robert P Anthonappa.
      Purpose: The purpose of this study was to assess the trends and evidence typology published in the journal Pediatric Dentistry over the last two decades (1999 to 2018). Methods: All articles from Pediatric Dentistry published between 1999 to 2018 were reviewed manually. Articles were assessed by topic, study design, level of evidence, source of funding, and country of origin. Letters to the editor, editorials, abstracts, short communications, practice guidelines, technical papers, and organization-related communications were excluded from the analysis. Results: A total of 1,311 papers from Pediatric Dentistry were included for the final analysis. Across the 20 years, cariology (12.7 percent) was the most published topic, followed by restorative dentistry (10.6 percent) and systemic diseases (9.4 percent). The quality of evidence varied from level Ia (1.0 percent), level Ib (9.7 percent), level IIa (1.1 percent), level IIb (15.0 percent), level IIc (5.0 percent), and level III (50.1 percent). Forty-three different countries contributed to this publication history, with the USA, UK, and Brazil accounting for over half of the articles. Conclusion: There has been an increase in both the quantity and quality of evidence published in Pediatric Dentistry articles between 1999 and 2018 versus the previous three decades (1969 to 1998).

    Update on the global neurosurgery movement: A systematic review of international vernacular, research trends, and authorship.
    Rosemary T Behmer Hansen, Ryan A Behmer Hansen, Virginia A Behmer, Justin Gold, Nicole Silva, Arjun Dubey, Anil Nanda.
      In 2015, key global and neurosurgical organizations increased collaboration to improve neurosurgical care access, delivery, and outcomes, particularly in low- to middle-income countries (LMICs); sparking what has been termed the global neurosurgery movement. The authors sought to assess trends in usage of the term 'global neurosurgery' in academic literature with particular focus on author affiliations, world regions most frequently discussed, and topics of research performed. A PubMed search for articles indexed as 'global neurosurgery' was completed yielding 277 articles which met inclusion criteria. It was found that over time, use of the term 'global neurosurgery' has increased, with increasing growth notable starting in the year 2008 and continuing into October 2019. Statistical comparisons showed authors with affiliated global neurosurgery centers were more likely to publish studies related to the continent of Africa (47.4% vs 15.9%, p < 0.001), and less likely to focus on countries in Asia (2.6% vs 20.9%, p = 0.023). Use of the term 'global neurosurgery' in the article abstract/title/keywords was associated with focus on LMICs (18.6% vs. 5.1%, p = 0.006). Use of the term 'global neurosurgery' was associated with workforce and capacity as research topics (41.9% vs 22.6%, p = 0.036). While fairly new, the global neurosurgery movement has seen a rapid increase in publications utilizing the term 'global neurosurgery.' Articles frequently have focused on collaborative, targeted workforce capacity building in LMICs. We encourage the development of more global neurosurgery academic centers, especially in non-USA countries, to continue this momentum.

    Maria Zulfiqar, Kiran Khurshid, Courtney C Moreno, Sabeena Jalal, Asra Nayab, Silvia D Chang, Sayani Sejal Khara, Faisal Khosa.
      BACKGROUND: Gender disparity exists in nearly every medical specialty, particularly in leadership roles and academia. Radiology is not exempt from this phenomenon, with women making up less than a third of radiology residents in the United States (US). This can have long-lasting effects on the career progression of female radiologists. Our search did not reveal any study on gender composition in academic abdominal radiology.PURPOSE: To evaluate the academic productivity and career advancement of female academic abdominal radiology faculty in the United States and Canada.
    MATERIALS AND METHODS: Parameters of academic achievement were measured, including the number of citations and publications, years of research, as well as H-index. Information regarding academic and leadership ranking among academic abdominal radiologists in the United States and Canada was also analyzed.
    RESULTS: In academic abdominal radiology, there were fewer females than males (34.9% vs 65.1%; p-value 0.256). Among the female radiologists, the greatest proportion held the rank of assistant professor (40%). Female representation decreased with increasing rank. Females had a lower H-index than males (P-value = 0.0066) and significantly fewer years of research than males (P-value = 0.0243).
    CONCLUSION: Male predominance in academic abdominal radiology is similar to many other medical specialties, and encompasses senior faculty rank, leadership roles and research productivity.

    Sex-Based Reporting of Common Musculoskeletal Conditions.
    Kelly Stumpff, Morgan Hadley, Karsen Corn, Kim Templeton.
      Introduction: Sex- and gender-based differences affect all aspects of health and disease, including musculoskeletal conditions. However, it is unknown how often authors publish outcomes of common conditions based on sex. We reviewed the frequency with which articles in orthopedic journals published sex-specific outcomes with regard to a condition with known sex-based differences and one in which differences are less known. Materials and Methods: Articles that reported original clinical studies from four high-impact orthopedic journals were reviewed: Journal of Bone and Joint Surgery (JBJS), Clinical Orthopedics and Related Research (CORR), American Journal of Sports Medicine (AJSM), and Journal of Arthroplasty (JOA). JBJS and CORR were reviewed as journals intended for a general audience, while AJSM and JOA were included as subspecialty journals. Analysis of data based on sex beyond the statement of how many men and women were included was designated as successfully reporting sex-specific outcomes. The gender of authors was assessed for impact on reporting. Results: Sex-specific outcomes were reported in 24%-29% of articles regarding rotator cuff pathology and in 32%-40% of publications concerning knee osteoarthritis. There was a trend toward more publications with sex-specific outcomes in knee osteoarthritis (p = 0.0562). No significant changes in rates of reporting were noted over time. Articles listing a woman as the first or last author were significantly more likely to report results based on sex. Conclusions: While there was a trend for sex-specific outcomes to be reported more often in knee osteoarthritis, the level of reporting was still low. Reporting based on sex was higher if a woman was the first or last author. To improve care for all patients, sex-specific outcomes should be reported across all orthopedic conditions by all researchers.

    Stakeholder engagement for innovation management and entrepreneurial development: A meta-analysis.
    S M Riad Shams, Demetris Vrontis, Ranjan Chaudhuri, Gitesh Chavan, Michael R Czinkota.
      This paper reviews contemporary studies in entrepreneurship literature related to innovation management (IM), stakeholder engagement (SE), and entrepreneurial development (ED), using bibliometric techniques and longitudinal statistical analysis of 1059 articles published in the Journal of Business Research (JBR) and other relevant business and management journals indexed in Scopus from 1974 until July 2020. We have employed a structured literature review and meta-analysis to explore the emerging research patterns in prospective observational studies encompassing the field of ED, SE, and IM. Our findings suggest that dynamics of the interaction of SE, IM, and ED are shaping the scholarship of academic research in entrepreneurship. Our meta-analysis reaffirms that contemporary research conducted at the intersection of SE, IM, and ED indicates the consolidation of these tenets in future research in entrepreneurship leading to an integrative view. Finally, we present future research directions at the intersection of SE, IM, and ED for entrepreneurship research.

    Climate change: Does international research fulfill global demands and necessities?
    Doris Klingelhöfer, Ruth Müller, Markus Braun, Dörthe Brüggmann, David A Groneberg.
      Background: Climate change is safe to be one of the biggest challenges of mankind. Human activities, especially the combustion of fossil fuels, contribute to the increase of greenhouse gases in the atmosphere and thus to the pace of climate change. The effects of climate change are already being felt, and the resulting damage will most likely be enormous worldwide. Because global impacts vary widely and will lead to very different national vulnerability to climate impacts, each country, depending on its economic background, has different options to ward off negative impacts. Decisions have to be made to mitigate climate consequences according to the preparedness and the vulnerability of countries against the presumed impacts. This requires a profound scientific basis. To provide sound background information, a bibliometric study was conducted to present global research on climate change using established and specific parameters. Bibliometric standard parameters, established socioeconomic values, and climate change specific indices were used for the analyses. This allowed us to provide an overall picture of the global research pattern not only in terms of general aspects, but also in terms of climate change impacts, its effects and regional differences. For this purpose, we choose representative indices, such as the CO2 emissions for the responsibility of countries, the global climate risk index as a combination value for the different types of damage that countries can expect, the increase in sea level as a specific parameter as a measure of the huge global environmental impacts, and the readiness and vulnerability index for the different circumstances of individual countries under which climate change will take place. We hope to have thus made a comprehensive and representative selection of specific parameters that is sufficient to map the global research landscape. We have supplemented the methodology accordingly.Results: In terms of absolute publication numbers, the USA was the leading country, followed by the UK, and China in 3rd place. The steep rise in Chinese publication numbers over time came into view, while their citation numbers are relatively low. Scandinavian countries were leading regarding their publication numbers related to CO2 emission and socioeconomic indices. Only three developing countries stand out in all analyses: Costa Rica, the Fiji Atoll, and Zimbabwe, although it is here that the climate impact will be greatest. A positive correlation between countries' preparedness for the impacts of climate change and their publication numbers could be shown, while the correlation between countries' vulnerability and their publication numbers was negative.
    Conclusions: We could show that there exists an inequity between national research efforts according to the publication output and the demands and necessities of countries related to their socioeconomic status. This inequity calls for a rethink, a different approach, and a different policy to improve countries' preparedness and mitigation capacity, which requires the inclusion of the most affected regions of the world in a strengthened international cooperation network.

    Presence of Social Media Mentions for Vascular Surgery Publications is Associated with an Increased Number of Literature Citations.
    Marvin Chau, Shayann Ramedani, Tonya King, Faisal Aziz.
      OBJECTIVES: The past two decades have seen a vast expansion of social media to all aspects of our lives. Scholars and journals are steadily increasing their social media presence to reach a wider audience. We aimed to compare social media mentions (SMs) of vascular surgery publications and their impact on the literature citations (LCs) for them.METHODS: One hundred and sixty-nine articles from 3 renowned vascular surgery journals (JVS, AVS, and EJVES) in October 2018 were collected. All three journals are published by the same publisher (Elsevier). SMs were tracked using Altmetric Bookmarklet for Twitter and Facebook mentions. The LCs were evaluated with Scopus and Google Scholar. The number of citations was compared between those with and without any social media mentions, as well as among the three journals, using nonparametric Kruskal-Wallis tests. The percentage of articles with SMs was compared among the three journals with a Chi-square test. The relationship between numbers of SMs and LCs was assessed using the Spearman rank correlation coefficient, and reported with 95% confidence intervals. Statistical significance was assigned at P<0.05.
    RESULTS: Out of the 169 articles examined, 51 (30.2%) articles had a presence regarding Social Media usage. JVS has both Twitter and Facebook presence. AVS and EJVES only have Twitter accounts. JVS had the highest total number of citations, number of LCs per manuscript, and SMs per manuscript. There was a significant difference in the median (Q1, Q3) number of total google citations between those papers with and without social media mentions (8.0 (3.0,17.0) vs. 3.0 (0.0,8.0), respectively, Kruskal-Wallis p<0.001). Similarly, there was a significant difference in the median number of total Scopus citations between those papers with and without social media mentions (5.0 (2.0,13.0) vs. 2.0 (0.0,6.0), respectively, Kruskal-Wallis p<0.001). Articles that had a social media mention showed a 2.7- fold increase in median total citations in Google and a 2.5-fold increase in median total citations in Scopus. The Spearman correlation coefficients to determine the relationship between the absolute number of SMs and LCs revealed positive but weak correlation, largely driven by the majority of articles with no social media mentions. There was not a significant difference in the median number of citations among the three journals, either by Google (p=0.22) or Scopus (p=0.08), nor was there a significant difference in the percentage of articles with SMs among the journals (p=0.36).
    CONCLUSIONS: The presence of SMs for vascular surgery publications, especially clinical science articles is associated with a significantly increased number of median LCs over three years after publication. The three journals did not differ with respect to median number of citations or percentage of articles with SMs.
