Background: Chemotherapy is crucial in the management of tumors, but challenges such as chemoresistance and adverse reactions frequently lead to therapeutic delays or even premature cessation. A growing body of research underscores a profound connection between the gut microbiota (GM) and cancer chemotherapy (CC). This paper aims to pinpoint highly influential publications and monitor the current landscape and evolving trends within the realm of GM/CC research. Methods: On October 1st, 2024, a comprehensive search for GM/CC publications spanning the past 20 years from 2004 to 2023 was conducted utilizing the Web of Science Core Collection (WoSCC). The scope encompassed both articles and reviews, and the data was subsequently extracted. To gain insights into the evolution and dynamics of this research field, we employed bibliometric analysis tools such as the Bibliometrix R package, VOSviewer, and Microsoft Excel to visualize and analyze various dimensions, including prominent journals, leading authors, esteemed institutions, contributing countries/regions, highly cited papers, and frequently occurring keywords. Results: A total of 888 papers were obtained. The number of publications about GM/CC studies has increased gradually. China and the United States published the largest number of papers. The INSERM was in the leading position in publishers. The most productive authors were Zitvogel L from France. Cancers had the largest number of papers. Citation analysis explained the historical evolution and breakthroughs in GM/CC research. Highly cited papers and common keywords illustrated the status and trends of GM/CC research. Four clusters were identified, and the hot topics included the role of the GM in the efficacy and toxicity of CC, the targeting of the GM to improve the outcome of CC, the mechanism by which the GM affects CC, and the correlation of the GM with carcinogenesis and cancer therapy. Metabolism, GM-derived metabolites, tumor microenvironment, immunity, intestinal barrier, tumor microbiota and Fusobacterium nucleatum may become the new hotspots and trends of GM/CC research. Conclusion: This study analyzed global publications and bibliometric characteristics of the links between GM and CC, identified highly cited papers in GM/CC, provided insight into the status, hotspots, and trends of global GM/CC research, and showed that the GM can be used to predict the efficacy and toxicity of CC and modifying the GM can improve the outcomes of chemotherapeutics, which may inform clinical researchers of future directions.

This study conducts an analysis of artificial intelligence (AI) and machine learning (ML) applications in natural disaster prediction using a scientometric approach. The Web of Science Core Collection served as the primary data source, yielding 38,456 records spanning from 2003 to 2022. The analysis concentrated on highly influential research, defined by papers garnering 100 or more citations, resulting in a final set of 1,637 publications. VOSviewer software facilitated the exploration of collaboration patterns among authors, institutions, and countries, along with the identification of emerging research topics and the most impactful articles. These highly cited papers were distributed across various sources (625). A total of 443,502 citations were counted, with an average of 270.92 citations per document. Interestingly, the average annual citation growth rate exhibited a negative trend (-1.02%), suggesting a potential shift in citation patterns over time. The average document age of 6.9 years indicates that the majority of the research is relatively recent. Collaboration emerges as a prominent feature within the field, with an average of 5.09 co-authors per document and 46.55% of collaborations being international. This underscores the collaborative nature inherent in research within this domain. Scholarly articles (1263) represent the predominant document type, followed by reviews (323), indicative of the field's solid foundation in peer-reviewed literature. The study's findings hold significant implications for future research and practical applications, identifying gaps in the literature and underscoring the necessity for further exploration in developing AI and ML models tailored to specific types of natural disasters, as well as assessing these models in real-world scenarios. International collaboration and interdisciplinary approaches are highlighted as pivotal components in advancing this critical field. While providing valuable insights, this approach acknowledges limitations associated with its focus on highly cited papers and a single database. Future research could address these limitations by incorporating additional databases, employing broader search criteria, and utilising alternative methodologies to attain a more comprehensive understanding of the evolving research landscape.

Purpose: Predicting highly cited papers can enable an evaluation of the potential of papers and the early detection and determination of academic achievement value. However, most highly cited paper prediction studies consider early citation information, so predicting highly cited papers by publication is challenging. Therefore, the authors propose a method for predicting early highly cited papers based on their own features. Design/methodology/approach: This research analyzed academic papers published in the Journal of the Association for Computing Machinery (ACM) from 2000 to 2013. Five types of features were extracted: paper features, journal features, author features, reference features and semantic features. Subsequently, the authors applied a deep neural network (DNN), support vector machine (SVM), decision tree (DT) and logistic regression (LGR), and they predicted highly cited papers 1–3 years after publication. Findings: Experimental results showed that early highly cited academic papers are predictable when they are first published. The authors' prediction models showed considerable performance. This study further confirmed that the features of references and authors play an important role in predicting early highly cited papers. In addition, the proportion of high-quality journal references has a more significant impact on prediction. Originality/value: Based on the available information at the time of publication, this study proposed an effective early highly cited paper prediction model. This study facilitates the early discovery and realization of the value of scientific and technological achievements. [ABSTRACT FROM AUTHOR]

Highly cited papers showcase high-quality research and encompass significant themes in the field. This study examined a total of 435 highly cited papers based on Essential Citation Indicators in the Web of Science (WoS) category of sport sciences with a bibliometric method. In particular, the bibliometric indicators of the highly cited papers including publication venues, authors, countries, institutions, and the top cited publications were presented and analyzed in detail. An Abstract corpus was constructed to help identify the most frequently explored topics. VOSviewer was employed to visualize the co-occurrence networks of keywords. The study revealed the trending information of important contributors at the levels of journals, authors, countries, and institutes. The top cited publications can be grouped into three categories: guidelines, recommendations based on systematic reviews, and evaluations. The most frequently explored topics based on the Abstract corpus and the most frequently used keywords from VOSviewer mapping overlap to a great extent. Specifically, topics such as meta-analysis, systematic review, sport-related concussion, sedentary behavior, football, rehabilitation, and osteoarthritis are among the most frequently mentioned. The results provide the most updated publication characteristics and hot topics of highly cited papers in sport sciences and offer insights for academic researchers in future research.

The primary objective of this paper was to provide insights into papers that garnered significant attention in news outlets. A sample of seventy academic papers, each with over 500 mentions in news outlets, was chosen for this study via Dimensions. Comprehensive data for each paper was extracted from diverse sources, encompassing the Journal Citation Report (JCR), Scopus, SCImago, Altmetric.com, as well as analyses of the titles and abstracts. Findings concerning the characteristics of these papers revealed that those highly referenced in news outlets tend to be predominantly published in open access within prestigious specialized journals, with a primary focus on medical and health-related topics. The majority of these papers have been published within the last three years, with each accumulating more than 100 citations in Scopus. Additionally, the results indicated that the number of authors and international collaboration does not exert a substantial influence on the frequency of news posts dedicated to highly mentioned papers in news outlets. However, the journal's impact factor, paper citation count, and the alignment of the paper's affiliation country with that of the news outlets displayed a notable correlation with the frequency of news posts pertaining to these papers. Based on the study's findings, it can be inferred that science journalists place higher emphasis on considerations such as proximity, prestige, timeliness, and relevance in their coverage, prioritizing these factors over other news values.

The research population includes 2747 highly-cited and hot papers of Iranian researchers indexed in Essential Scientific Indicators (ESI) and Web of Science (WoS) databases during 2010-2019. The research tool is an “advanced search” tool of the Web of Science database. For this purpose, first, articles related to Iran during 2010-2019 were extracted from the Web of Science database. By searching Iran, all the articles were retrieved. By limiting the search to highly cited articles and hot papers science scholars during 2010-2019 were extracted. Data was collected by Microsoft Excel software and analyzed by correlation and regression tests using SPSS (version 22) software. Findings: The largest number of scientific collaborations included the United States (534), China (449), and the United Kingdom (338). Findings showed the most collaborations in highly cited and hot articles published in 2018 and 2019. Also, the most collaborations in writing highly cited articles in the subject areas were engineering with 374 (33710 citations), Physics with 155 (26158), and clinical medicine with 154 (60397 citations); Furthermore, the most cooperation in writing hot articles in the subject areas of engineering with 18 (983 citations), materials science with 14 (253 citations), and clinical medicine with 12 (1686 citations). Findings showed that the number of highly cited articles with the cooperation of two countries was 566 (50266), for three countries it was 274 (24351), for more than 15 countries it was 226 (86575), and the number of hot papers with the cooperation of two countries was 22 (713), for more than 15 Country it was 19 (1914), for three countries it was 12 (339). Findings showed that a positive and significant relationship was observed between the number of international collaborations and the number of citations received (without self-citation) of highly cited and hot papers. Whenever the coefficient becomes significant in the regression model, it means that in the regression model, the predictor variable has an effect on the dependent variable. If the value of P is less than a, the coefficient is significant. The regression model on the research variables with the presence of the predictor variable (the number of highly cited articles). In general, the number of collaborations is presented as the most suitable model that explains the variance of the criterion variable (number of citations) and the test is positive and significant. The findings show that the relationship between countries' researchers' cooperation and the number of citations received by highly cited articles is a strong, positive, and significant predictor. Conclusion: Based on this, with the increase in cooperation, we see an increase in the number of cited articles by Iranian researchers. The results showed that there is a positive and significant relationship between the number of international collaborations of article researchers and the number of citations received.

Due to recent advances in communication systems, dielectric and magnetic ceramics (ferrites) are attractive for use in devices. Spinel-type ferrites were the first material utilized in microwave devices; however, yttrium iron garnet (YIG) has low dielectric losses and is exploited in many applications. Owing to its high Faraday rotation, YIG films are utilized in magneto-optical applications. This study intends to examine the research trends and scientific research progress on highly cited papers discussing YIG films published between 2012 and 2022 using a bibliometric method. A comprehensive review of 100 scientific papers about YIG was performed from the Scopus database. The assessment of these highly cited papers was highlighted based on the following factors: publication trends and performance, limitations/research gaps, keywords, sub-fields, methodology journal evaluations, document type evaluation, issues, difficulties, solutions, and applications as well as guiding future YIG research. The majority of publications (99%) comprise experimental analysis, whereas 1% provide a based state-of-the-art overview. Ninety-one percent of articles focused on magnetization characterization. This bibliometric survey indicates that YIG film research is an expanding and developing field. The results of the data analysis can be utilized to improve the researchers' understanding of YIG research and to encourage additional study in this area. [ABSTRACT FROM AUTHOR]

[Purpose / Signficance] The current competition of comprehensive national strength relies more on fundamental research, and highly cited papers have important significance in the evaluation and analysis of fundamental research. Revealing the differences between China and USA in leading basic research from the perspective of highly cited papers, we provide basic data support for national scientific research management decision-making and institution building. [Method / Process] Based on ESI highly cited papers of China and USA, this article uses bibliometric methods and Y index to analyze the specific features and differences of China and USA among three dimensions—trends of publication, country cooperation and institutional output.[Results / Conclusions] The study shows that: (1) Overall, the highly cited papers of China is 2.99 times that of the American highly cited papers, but the gap is narrowing yearly. At the same time, the low citation frequency and the low proportion of highly cited papers are still the shortcomings that limit Chinese international influence. (2) China and USA are closely cooperating with each other. USA dominates scientific research cooperation, as the proportion of first authors and corresponding authors and leading papers is significantly higher than that in China. (3) Chinese high-output institutions have obvious advantages of corresponding authors, but the output gap between institutions is large. And the American high-output institutions are evenly distributed, and they are characterized by deeper and broader international cooperation and inter-agency cooperation.

The study of ecosystem services (ES) is becoming increasingly popular, as it plays an important role in human wellbeing, economic growth, and livelihoods. The primary goal of this research is to investigate the global trend in ES research using a rigorous systematic review of highly cited articles. The articles for this study were extracted from Science Citation Index Expanded (SCI-E), Emerging Sources Citation Index (ESCI), and Social Sciences Citation Index (SSCI) databases of Web of Science Core Collection (WoSCC) covering the period from 2000 to 2020. This study was limited to SCI-E, ESCI, and SSCI databases of the Web of Science. The term "ecosystem service/s" has been used as a research term to filter the study sample and eliminate other databases from the analysis. A citation level equal to or greater than 200 was used to further filtration of articles. This query could restrict to 128 articles that are highly cited in the selected period. Bibliometric analysis results show that, according to the author's keywords, the "ecosystem service/s" keyword is highly connected to the "biodiversity", "valuation", "marine spatial planning", and "conservation planning". The U.S.A., Canada, China, France, and Australia are the leading countries in the cumulative number of highly cited articles and networks of co-authors. The U.S.A. is a strong contributor to ES research with China, Canada, and France. The most productive universities linked to the United States were the University of Minnesota, the University of California-Santa Barbara (UC Santa Barbara), and the Chinese Academy of Science. The most significant and compelling author is Halpern S Benjamin, who represents UC Santa Barbara. He has earned international recognition for a model he developed to analyze global data sets of anthropogenic drivers of ecological change in marine environments. The most accessed and studied fields in the ES are terrestrial, urban, and marine environments. [ABSTRACT FROM AUTHOR]

Due to recent advances in communication systems, dielectric and magnetic ceramics (ferrites) are attractive for use in devices. Spinel-type ferrites were the first material utilized in microwave devices; however, yttrium iron garnet (YIG) has low dielectric losses and is exploited in many applications. Owing to its high Faraday rotation, YIG films are utilized in magneto-optical applications. This study intends to examine the research trends and scientific research progress on highly cited papers discussing YIG films published between 2012 and 2022 using a bibliometric method. A comprehensive review of 100 scientific papers about YIG was performed from the Scopus database. The assessment of these highly cited papers was highlighted based on the following factors: publication trends and performance, limitations/research gaps, keywords, sub-fields, methodology journal evaluations, document type evaluation, issues, difficulties, solutions, and applications as well as guiding future YIG research. The majority of publications (99%) comprise experimental analysis, whereas 1% provide a based state-of-the-art overview. Ninety-one percent of articles focused on magnetization characterization. This bibliometric survey indicates that YIG film research is an expanding and developing field. The results of the data analysis can be utilized to improve the researchers’ understanding of YIG research and to encourage additional study in this area.

Child nutrition has always been a global concern. This study performed visual analysis of 1,398 child nutrition highly cited papers (HCPs) from 2009 to 2019. The purpose of the study was to evaluate and present the performances of authors, journals, countries, institutions, top cited papers; to explore the hot topics, prospects, and to propose the future research directions on child nutrition. We used bibliometric methods to conduct in-depth statistical analysis of HCPs on child nutrition, showing research progress, trends and hot spots. We included HCPs on child nutrition from the Science Citation Index-Expanded (SCI-E) database February 7, 2020. Two tools, CiteSpace and VOSviewer, were used to conduct the bibliometric analyses. The results showed that, since 2011, the number of HCPs on child nutrition has increased rapidly. The top three contributors in this field were the USA, the UK and Canada. However, the contribution of developing countries was very limited. Intestinal microflora, food allergy, overweight and obesity were the three major research hotspots in this field. Results of this study provide valuable references for ongoing child nutrition related research, which may be interesting and noteworthy to the researchers involved.

Objective To analyze the international scientific research collaboration network of coronavirus disease 2019（COVID-19），and provide reference for researchers to grasp the research status and explore collaborative paths in future. Methods The ESI highly cited papers on COVID-19，which were collected from the core collection of Web of Science，were divided into four stages according to the publication time，and the multivariate statistics and social network analysis were used to reveal the international research collaboration rate，team size，collaboration network characteristics and its evolution rule. Results Up to Apr 30，2021，a total of 3 794 ESI highly cited papers were initially collected. According to the literature screening criteria，3 715 papers were finally included in the current research. The overall international research collaboration rate reached 34.27%. Among the 10 countries with the highest number of papers published，China had the lowest research collaboration rate （34.53%） with other countries，and the rests were more than 50%.The collaboration rate between China and the United States showed a gradual downward trend in the four stages. The overall scientific research team size showed an upward trend in general. In the entire scientific research collaboration network，the second stage was the largest and the most compact one，Since then the network scale became shrinking，and the collaboration network had been gathering to the center. The core degree of China in the first stage was 0.741，indicating that China was at the core position. Since then the United States replaced China and became the core of the scientific research collaboration network，and England came in second. Conclusion The overall level of international scientific research collaboration of COVID-19 is high，and the collaboration network presents a trend of centripetal aggregation.The United States is still the core of the collaboration network.

Citation count fails to comprehensively and accurately portray the publication's impact, and the scientific impact is far more than what we see on the surface. This paper proposes a new impact indicator, the Contribution-Weighted Citation index, in which each citation is weighted from the perspective of the citing item. The method of weighting is based on ranking of the 'old' impact values of articles published in the same year and same field, and modifies the value of one citation from each publication positively or negatively. The idea of iteration is introduced into the calculation process for more accurate results. We empirically analysed 3,847,243 papers from the WoS database for the 1978–2017 period, including the fields of Mathematics, Physics, and Space Science. The experimental results show that the three variants of the new index proposed in this article show different characteristics in identifying article impact. Our new indicator in sine mode make articles more discrete, which helps distinguish between papers with similar citation count, while the arcsine mode is more helpful to identify high-citation-quality papers. In addition, we found the average citation quality of lowly cited papers fluctuates greatly, and some such papers have surprisingly high citation quality; for highly cited case, the average citation quality stabilizes in a certain range. This article has a positive role in identifying important publications and under-cited publications. [ABSTRACT FROM AUTHOR]

Highly cited papers are among the most commonly used indicators for measuring scientific excellence. The primary purpose of this study is to determine characteristics of highly cited papers authored or co-authored by Croatian researchers and to identify patterns of their national and cross-national collaboration. The Clarivate Analytics Web of Science Core Collection was used for collecting data. Data were filtered for the highly cited papers published in the 2008-2018 period. Half of 428 identified highly cited papers were published in only 18 journals. The distribution across subject areas showed a strong domination of the fields of physics and clinical medicine. The median number of authors per average paper was 30,5, while the same value in the case of Croatian authors was 2. Only 4% of the analysed papers were authored by Croatian researchers only. The national inter-institutional collaboration was marginal and mainly visible through joined collaboration with foreign institutions. European institutions are most frequently found among the authors' addresses. For a small country on the scientific periphery, international cooperation is a prerequisite not only for the publication of highly cited papers but also for acquiring additional research experience in mainstream scientific teams.

The objective of this study was to analyze the top papers from Organization of Islamic Cooperation (OIC) member countries covered in the Essential Science Indicators (ESI) database during 2010-2019. The findings of the study showed that 41 out of 57 OIC member states have published 7,369 highly cited papers and 249 hot papers. The leading countries based on the overall top papers produced were Saudi Arabia, followed by Iran, Turkey, Malaysia, Pakistan and Egypt. Iran was ranked first in terms of hot papers. When analysed by document type, all of the top papers were articles and published in the English language. The Lancet ranks among the top in terms of publishing OIC member countries' top papers, showing that it has a great academic influence producing highly cited papers and hot papers. The top five organizations producing top papers are all top universities in their country and they are also ranked globally. King Abdulaziz University contributed the most for both highly cited papers and hot papers. NANOFLUID was the most common keyword and core subject in highly cited papers, and the keyword MECHANICAL-PROPERTIES was the core subject identified in hot papers. Cluster 1 is the largest subject cluster of highly cited papers with the topic Nanotechnology and it is also the largest cluster of hot papers. [ABSTRACT FROM AUTHOR]

The purpose of this paper is to retrieve and study the highly cited papers as well as the correlation between the citation frequency and the download frequency of the 20 traditional Chinese medicine journals in China, in order to provide the guidance for improving the influence and academic quality of these journals. Bibliometric analyses were conducted on 1103 papers of 20 traditional Chinese medicine journals from 2011 to 2020 by retrieving for the China Academic Journal Network Publishing Database (CAJD) in China National Knowledge Infrastructure (CNKI). SPSS 17.0 software was used to analyze the correlation between the citation frequency and the download frequency via conducting regression fitting and establishing the mathematical models. The results showed that the total citations of the 1103 papers were 93051 times and the average citations were 84.36 times per paper. The total downloads of the 1103 papers were 2058442 times, and the average downloads were 1866.22 times per paper. China Journal of Chinese Materia Medica ranked first according to the number of papers, total citations and total downloads. The citations of Journal of Chinese Medicinal Materials ranked first based on the number of citations per paper. One of Li's paper had been cited the most (983 times). There were 629 (57.03%) papers whose first author was from universities. The scopes of the first authors were distributed in 29 regions and 2 special administrative regions (Macao, Hong Kong) in China. The authors from Beijing published 283 (25.66%) papers, ranking number one. The number of papers supported by funds was 882 (79.96%). The research results of correlation showed that the citation frequency and the download frequency of the highly cited papers had a highly positive correlation from both journal and paper level for whether the sample data of journals was normally distributed or nonnormally distributed. The correlation coefficients of the 20 journals at journal level and that at paper level were 0.9765 and 0.6677, respectively. The correlation was better at journal level than that at paper level, while the optimal regression fitting was all cubic polynomial. Among the 1103 papers, there were 684 (62.01%) research papers and 419 (37.99%) review papers. The main citation period of the top 15 papers was from the 2nd year to the 6th year after publication, accounting for 78.39%. Papers on clinical therapeutics research, papers on the pharmacological effects and its mechanism of traditional Chinese medicine, and papers on traditional Chinese medicine and natural medicine were the main source of the highly cited papers of the traditional Chinese medicine journals. Editors of the journals should focus on the above-mentioned research areas to select manuscripts for exploiting the excellent sources extensively, while paying attention to review papers, focusing on national major or key projects, paying attention to network spreading, stabilizing authors with quality services, in order to improve the influence and the academic quality of journals.

[Purpose/Significance] "The Belt and Road" is an initiative proposed by China in recent years to cooperate and develop a community with a shared future for mankind, which has been continuously highly concerned by all circles at home and abroad. From the perspective of the citation of highly cited papers, the academic exchange of countries along the Belt and Road initiative cam provide a quantitative reference for future international academic and technological exchanges, collaborative innovation and development. [Method/Process] Based on the highly cited papers among the countries along the "The Belt and Road" in the WoS database from 2013 to 2018, this paper constructed a reference matrix and analyzed the network structure, and drew a national citation network map for cluster division. Furthermore, it explored the current state of academic exchange along the "The Belt and Road" and the direction of Chinese academic output, and further analyzed the correlation between Chinese academic exchanges and trade cooperation with other 64 countries along the route. [Results/Conclusions] The research results show that the countries along "The Belt and Road" have close academic exchange and obvious "small world" characteristics. China is the core of academic exchange and the highly cited papers in many research directions in China are cited by many countries along "The Belt and Road". Besides, academic exchange and trade cooperation between China and countries along "The Belt and Road" are strongly related. [ABSTRACT FROM AUTHOR]

This paper presents a methodological proposal based on the identification of highly cited papers (HCPs) at domestic-level in the Spanish Public University System (SUPE), in order to find the most outstanding publications in the local context. The principal aim is to detect different activity and impact profiles among Spanish universities and differentiate those institutions that play a more significant role. To determine which and how many are the highly cited papers at the domestic level (HCP-DL) collected in the Web of Science, three citation thresholds (1, 5, and 10%) were established. Thematic classification in Incites/Essential Science Indicators areas is used. The results show a preponderance of HCPs in the field of Space Science, while the polytechnic universities have high visibility in the Computer Science area. It has been observed that the presence of HCPs in a given area is involved with universities specialized in teaching and research activities. In absolute terms, the big non-specialized universities are major producers of HCPs and hold the leading positions in our results. However, when efficiency is analyzed in relative terms, some small, specialized universities reveal themselves to be more efficient at producing HCPs (% of HCPs or citations per HCP). We think that this methodology, due to its simplicity, its ease of calculation, and the knowledge it provides, can be very useful to analyze the national systems of any country, in order to know the impact and visibility of the research carried out in its scientific institutions or research areas.

Background and Aims: We provide an overview and data visualization trends of orthopaedic research published by the Journal of Orthopedics (JOO) from 2013 to 2024., Methods: We used Scopus database to retrieve all articles published by the JOO from 2013 to 2024, as of 15.7.2024. Bibliometric analysis and visualization of the global orthopaedic literature were performed using Microsoft Excel and VOSviewer software to explore the research hotspots in this field in the past 12 years., Results: The 2074 publications covered in the JOO published between 2013 and 2024 were identified. The annual average and six-year cumulative publications depicted growth rates of 36.23 % and 147.99 %, respectively. Of the 80 global publications, the main participating countries were from Europe (n = 26), and Asia (n = 13). North America (37.37 %), Europe (34.89 %) and Asia (30.42 %) contributed a significant share of journal output. The most contributing countries were the USA, followed by the U.K., India, and Japan. The visualization and analysis of topical research trends reveal that the JOO covers almost the entire spectrum of orthopaedic research, with the most focus on the Knee (26.38 %), Hip (21.53 %), Shoulder (8.79 %) and Spine (7.09 %) and its subfields, such as arthroplasty (882 papers), surgery (192 papers), radiography (177 papers), osteoarthritis (166), pain (135 papers), fractures (133) and arthroscopy (70). The 68 (3.32 %) of the 2047 publications received 30 and above citations and together received 3466 citations, constituting 51.73 % share of total citations. The Hospital for Special Surgery (USA), and Singapore General Hospital were the most productive organizations, while the most impactful organizations were the University of Toledo Medical Center (USA), and Università degli Studi di Messina (Italy). The most productive authors were R. Vaishya (India), and J.A. Dubin (USA), whereas V. Filardi (Italy) and J.M. Newman (USA) were the most impactful authors of the JOO., Conclusion: The JOO is a destination for global orthopaedic research. It has progressively received an increasing number of manuscripts and depicted high annual average publication growth rates, besides witnessing an increase in the significant number of citations received. It has helped to improve the journal's ranking, impact and reputation., Competing Interests: We wish to confirm that none of the authors have any competing interest related to this manuscript. However, the Authors #1,2,3 are on the editorial board of the Journal of Orthopaedics, but will not have any role in the editorial review and decision making on this article., (© 2024 Professor P K Surendran Memorial Education Foundation.

This study aims to investigate Iran scientific production pre-revolutionary by 2016 with the emphasis on the conferences proceedings, highly cited and hot papers, and open access papers, in the light of the Law of Economic, Social, and Cultural Development Plan of Iran. Descriptive– analytical method used. To achieve research objectives data extracted from Clarivate Analytics (Thomson Reuters) using search strategy CU=IRAN. Analysis is based on conferences proceedings, highly cited and hot papers, and open access papers indexed in Web of Science during 1931- 2016. The findings showed that the conferences papers had a significant growth over time, and in general, before the Islamic Revolution, no conferences papers from Iran were registered in this database, and the growth of these articles was after the victory of the Islamic Revolution, so that from one conference paper in 1989 to 3529 articles in 2015 (and 502 papers for first seven months in 2016). Also, the status of highly cited and hot papers indicates that in general, these papers have been compiled from 1134 highly cited papers since 2006 and 45 are hot papers that have been registered in this database. On the other hand, the status of open access articles suggests that the researchers are more likely to welcome these articles. However, the significant growth of these articles dates back to the fourth decade, with 25813 open access papers, most of which are published in 2015 with 4502 papers. The findings showed that the annual compound growth of conference papers over the second period of the second development plan was 47.12%, which shows a decrease in the third plan (19.64%) with a negative growth of 8.38%. In the fourth plan, the growth rate of the articles of the conferences is 35.37% and represents 6.6% growth more than third plan. Between the fifth and fourth plans, we experience 18.82% of downtrend. There is no negative growth in the highly cited and hot papers between the second and the fifth plans, but the growth of these papers is not impressive. During the first to fifth plans, the development of open access articles has been significant, but the growth rate of a five-year plan is not prominent to another plan. In this regard, the findings showed that in the fifth development plan, we observed a decrease of 6.59% compared to the fourth plan. Although Iran has achieved a high status in terms of scientific quantity, it is necessary to pay more attention to applied quality research, in accordance with the Law of the Economic, Social, and Cultural Development Plan of Iran, and the responsible bodies and planners must prioritize this issue. With the efforts of the Iranian scholars and the necessary support in this regard, the influential presence of science and technology in the welfare of society is observed.

Purpose: As a pioneering and influential journal in the field of library and information science (LIS), the Journal of Documentation (JDoc) needs to be evaluated from a bibliometric perspective. This study aimed at conducting a bibliometric overview and visualization of the scientific output of JDoc from its inception in 1945–2018. Design/methodology/approach: In this bibliometric study, 2056 papers published in JDoc were analyzed. All needed data were extracted from Scopus in 9 July 2019 in CSV format. Bibliometric analyses were done in Microsoft Excel. Visualization was done by Vosviewer software and applying techniques such as co-citation, co-authorship and co-occurrence. As a limited altmetric study, JDoc highly mentioned papers and the rate of their presence in social media were extracted from Altmetric LLP, too. Findings: There was an increasing trend in published papers and received citations. Highly cited and most influential authors in JDoc are well-known in the field. However, the contributions of developing countries and their affiliated institutions to the journal were relatively low. This is true in case of author, country and institute co-authorship patterns. Highly frequent keywords and keyword co-occurrence patterns showed that the journal considered most topics related to LIS, including newly emerged ones. The authors and sources (generally journals) cited by JDoc are all prolific and influential ones. Originality/value: The results of this study can be beneficial to JDoc editorial team for decision making on its further development as well as helpful for researchers and practitioners interesting in LIS field to have better contact with and contributions to the journal.

International scientific collaboration, a fundamental phenomenon of science, has been studied from several perspectives for decades. In the spatial aspect of science, cities have generally been considered by their publication output or by their citation impact. Only a minority of scientometric studies focus on exploring collaboration patterns of cities. In this visualisation, we go beyond the well-known approaches and map international scientific collaboration patterns of the most prominent science hubs considering both the quantity and the impact of papers produced in the collaboration. The analysis involves 245 cities and the collaboration matrix contains a total number of 7718 international collaboration links. Results show that US–Europe co-publication links are more efficient in terms of producing highly cited papers than those international links that Asian cities have built in scientific collaboration.

This study aimed to investigate the topical areas and collaboration patterns of North Korean researchers. To conduct this study, bibliographic records of researchers affiliated with institutions in the city of Pyongyang for the years from 2002 to 2018 were retrieved from the Scopus database. The results showed disproportional levels of collaboration with China and the marginal level of research papers. North Korean researchers seemed to have worked on labor-intensive subject areas that have both civilian and military applications. The results implied that North Korea is only making modest levels of contributions to the global academic community. The increase in the number of international journal papers authored by North Korean researchers can be considered as a side benefit of maintaining a close relationship with China. The collaboration patterns of North Korea and China seemed to reflect China's engagement policy toward North Korea and the rapid rise of China's scientific research production in recent years. The results of this study should be taken into consideration in the design of national policies that tolerate or inhibit collaboration with North Korean researchers. [ABSTRACT FROM AUTHOR]
