The Scientific Contribution of Malaysia’s Researchers in the Field of Endodontics Based on Scopus Database: A Bibliometric Analysis

Bibliometric analyses of academic output are critical in assessing a country’s scientific performance and have ignited significant interest in recent days. However, no such study has been conducted in the field of dentistry, specifically endodontics, among Malaysia’s researchers. Hence, this study aimed to assess the publication output among researchers in Malaysia dedicating to endodontics based on the Scopus database and analyse the characteristics of selected articles as well as the publishing patterns. An electronic search based on the Scopus® database was performed from January 2001 to February 2021. Only English language articles with the first author’s affiliation from Malaysia were selected and the following parameters were extracted: title, authors, number of authors, affiliation, journal, year of publication, type of article, source, thematic categories, keywords, and number of citations. Data was analysed using Microsoft Excel software complemented by Pearson’s Chi-square and Pearson Correlation tests at 0.05 significance level. There were 119 articles included with the top-cited article received 69 citations. A total of 15 authors have 2 or more articles published, with the International Endodontic Journal published the most. Furthermore, more than half of the articles were published in Q1 and Q2 journals. Over the last two decades, there has been a substantial growth (P<0.05) in the number of articles and cumulative citations, with a significant correlation (P=0.038) between them. Besides, the Department of Conservative Dentistry and Universiti Sains Malaysia published the most articles, with the bulk of them being basic research on endodontic materials. In conclusion, the rise in scientific publications suggests an increasing interest in endodontics among Malaysia’s researchers.

Bibliometric Analysis of the Scientific Literature on Rheumatoid Arthritis-Associated Interstitial Lung Disease

Background. In recent years, the number of studies on rheumatoid arthritis-related interstitial lung disease (RA-ILD) has been increasing, which has led to many publications on this topic. Our purpose is to identify research trends in RA-ILD and analyze the most-cited RA-ILD-related high-quality scientific publications. Methods. All publications on RA-ILD in the Core Collection database of Web of Science were searched. The publication year, country, institution, total citations, and journal were extracted and analyzed. We used VOSviewer software or an online bibliometric analysis platform for cooccurrence analysis of the keywords, institutions, and countries involved. The 100 most frequently cited RA-ILD publications were analyzed. Results. In total, 596 publications related to RA-ILD were obtained. Over time, the frequency of RA-ILD publications has increased. Globally, the United States provides the most publications on RA-ILD ( n = 195 ). The institution with the highest publication output was the Mayo Clinic ( n = 43 ). The journal “Annals of the Rheumatic Diseases” published most with 93 articles and received 338 citations. A clinical description was the most common research topic in RA-ILD-related publications. Conclusions. In recent years, there has been an increasing number of studies on RA-ILD, and related publications have increased rapidly. This study is the first bibliometric study of RA-ILD-related publications. It can be used as a guide for clinicians and can help researchers choose research directions of interest in this field.

Generational differences in international research collaboration: A bibliometric study of Norwegian University staff

This paper addresses the relationship between age and international research collaboration. The main research question is: do younger researchers collaborate more internationally than their senior colleagues? A common assumption is that younger generations are generally more internationally oriented than older generations. On the other hand, senior researchers may have larger international networks compared to younger colleagues. The study is based on data for 5,600 Norwegian researchers and their publication output during a three-year period (44,000 publications). Two indicators for international collaboration are used: The share of researchers involved in international collaboration measured by co-authorship and the average proportion of publications with international collaboration per researcher. These indicators reflect two different dimensions of international collaboration. Although the findings are not consistent across age cohorts and indicators of internationalization, the overall trend is that international collaboration tends to decline with increasing age. This holds both at aggregate levels and within groups of academic positions. However, the generational differences are not very large, and other variables such as the field of research explain more of the differences observed at an individual level.

Mapping of the Research Output in Food Economics: A Scientometrics View of the Scopus Database

Since food is considered important in the world, the current study analyzed the characteristics of scientific publications based on several subtle indicators of scientometrics in the field of food economics for strengthening public health in the future. Accordingly, a total of 26306 publications from 1915 to 2021 are evaluated based on the Scopus database with the help of scientific tools such as Hitcite, Biblioshiny and VoS viewer. The results show that the resourcefulness experts are identified in terms of their publication only, that namely Drewnowski, Kesselheim. On the other hand, the author Popkini is considered as the key author rather than the above-said authors in terms of global citations. The similarity in the above context is that all the topmost authors belong to the USA. More importantly, the summary of citations in total publication output is revealed that a single paper is recorded the range of citations between 1042-2766, the 500 citations are recorded from the 64 papers, and 844 papers accounted with more than 100 citations.

Research Trends and Focus on the Deserts of Northern China: A Bibliometric Analysis During 1986–2020

With the economic progress and scientific development since the 1980s, research on deserts in China has advanced remarkably. Many research outputs have been published, especially in recent years. However, a systematic review and quantitative analysis of these publications has been lacking. Here, we conducted a comprehensive bibliometric analysis of the main deserts in China in order to characterize the trends and temporal changes in publications. Because the first publication was found in 1986, we searched all publications from 1986 to 2020. We found that annual publication output increased exponentially, especially after 2012, and that the Tengger Desert, the Taklimakan Desert, and the Horqin Sandy Land were the most intensively studied areas. Earth science, involving environmental science and ecology, geology, and agriculture were the major research fields. In addition, Journal of Arid Land, Chinese Science Bulletin, and Catena were the journals with the largest number of publications. The Chinese Academy of Sciences produced the largest number of publications, wherein, Li X R, Zhao X Y, and Zhang Y M were the three most productive authors. Noticeably, “climate change” has become a frequent topic since 2010, indicating that more attention has been paid to climate change and alleviating anthropogenic disturbances in desert areas in China. Although Chinese authors contributed the most publications, the average number of citations per publication for Chinese authors was relatively low. Our results highlight that authors should continue to improve the number of citations of their publications and pay more attention to the interactions between climate change and desertification in the deserts research of Northern China in the futures.

Bibliometric Analysis of Global Research Trends on Group Buying using Scopus Database

In this digital age, consumers have embraced online shopping, whereby the group buying (GB) strategy has been widely applied in online shopping. Therefore, it is noteworthy to decipher the global development trend of GB within the online platform. As such, this study evaluated the global research trends in GB based on publication output, co-authorship between authors and affiliated countries, as well as co-occurrence of author keywords. By deploying the bibliometric method on Scopus database, 349 journal articles published between 1957 and 2020 were retrieved. The results revealed that since 2011, the publications of GB began to increase rapidly, while the number of publications prior to 1999 was only 54, of which 38 were related to the medical field. Interestingly, researchers from China and the US contributed about 50% of the world's publications. Meanwhile, author keywords showed that vast research work had higher assertions with online GB (OGB) marketing and Internet technologies.

Bibliometric Analysis in the Field of Quantum Technology

The second quantum technological revolution started around 1980 with the control of single quantum particles and their interaction on an individual basis. These experimental achievements enabled physicists, engineers, and computer scientists to utilize long-known quantum features—especially superposition and entanglement of single quantum states—for a whole range of practical applications. We use a publication set of 54,598 papers from Web of Science, published between 1980 and 2018, to investigate the time development of four main subfields of quantum technology in terms of numbers and shares of publications, as well as the occurrence of topics and their relation to the 25 top contributing countries. Three successive time periods are distinguished in the analyses by their short doubling times in relation to the whole Web of Science. The periods can be characterized by the publication of pioneering works, the exploration of research topics, and the maturing of quantum technology, respectively. Compared to the USA, China’s contribution to the worldwide publication output is overproportionate, but not in the segment of highly cited papers.

More journal articles and fewer books: publication practices in the social sciences in the 2010’s

Over the past few years, the rate of journal article publication has increased in most academic disciplines - in some cases more than doubling in the past decade. While journal articles are the de facto currency of knowledge production in many science disciplines, social science scholars routinely publish books as well as journal articles. The social sciences have also undergone a rapid transformation towards more quantitative methodologies, thus representing a unique opportunity to study the increased rate of journal article publication in an area where books are also an important mode of dissemination. We studied the publishing activity of social sciences faculty members in 12 disciplines at 290 Ph.D. granting institutions in the United States between 2011 and 2019. In all disciplines, journal articles per person increased between 2011 and 2019 by between 3% and 64%, while books per person decreased by at least 31% and as much as 54%. Overall, early career researchers show the largest increase in rates of journal article production, while senior scholars show the greatest increase in participation in journal article production. Younger scholars appear to have greater publication output, while growing numbers of older scholars turn towards journal articles as a means of disseminating their work in the social sciences. We observe growing uniformity in the disciplinary literatures of the social sciences, which increasingly resemble the physical and biological sciences in terms of publication practices.

Bibliometric Analysis of Current Status on Bioremediation of Petroleum Contaminated Soils during 2000–2019

Petroleum contaminated soils have become a great concern worldwide. Bioremediation has been widely recognized as one of the most promising technologies and has played an important role in solving the issues of petroleum contaminated soils. In this study, a bibliometric analysis using VOSviewer based on Web of Science data was conducted to provide an overview on the field of bioremediation of petroleum contaminated soils. A total of 7575 articles were analyzed on various aspects of the publication characteristics, such as publication output, countries, institutions, journals, highly cited papers, and keywords. An evaluating indicator, h-index, was applied to characterize the publications. The pace of publishing in this field increased steadily over last 20 years. China accounted for the most publications (1476), followed by the United States (1032). The United States had the highest h-index (86) and also played a central role in the collaboration network among the most productive countries. The Chinese Academy of Sciences was the institution with the largest number of papers (347) and cooperative relations (52). Chemosphere was the most productive journal (360). Our findings indicate that the influence of developing countries has increased over the years, and researchers tend to publish articles in high-quality journals. At present, mainstream research is centered on biostimulation, bioaugmentation, and biosurfactant application. Combined pollution of petroleum hydrocarbons and heavy metals, microbial diversity monitoring, biosurfactant application, and biological combined remediation technology are considered future research hotspots.
