Objective: This study aimed to analyze the progression and trends of multimorbidity in the elderly in China and internationally from a bibliometric perspective, and compare their differences on hotspots and research fronts. Methods: Publications between January 2001 and August 2021 were retrieved from WOS and CNKI databases. Endnote 20 and VOSviewer 1.6.8 were used to summarize bibliometric features, including publication years, journals, and keywords, and the co-occurrence map of countries, institutions, and keywords was drawn. Results: 3857 research papers in English and 664 research papers in Chinese were included in this study. The development trends of multimorbidity in the elderly are fully synchronized in China and other countries. They were divided into germination period, development period, and prosperity period. Research literature in English was found to be mainly focused on public health, and the IF of the literature is high; In China, however, most research papers are in general medicine and geriatrics with fewer core journals. Co-occurrence analysis based on countries and institutions showed that the most productive areas were the United States, Canada, the United Kingdom, and Australia, while the Chinese researchers have made little contribution. The clustering analysis of high-frequency keywords in China and around the globe shows that the hotspots have shifted from individual multimorbidity to group multimorbidity management. Sorting out the top 10 highly cited articles and highly cited authors, Barnett, K’s article published in Lancet in 2012 is regarded as a milestone in the field. Conclusion: Multimorbidity in the elderly leads to more attention in the world. Although China lags behind global research the research fronts from disease-centered to patient-centered, and individual management to population management is consistent.

For researchers in the global South, international recognition in science arguably involves engaging with the norms, ideas, and people leading research activity in the global North. This article explores the relationship between international research collaboration and the publication activity of highly cited researchers in Brazil, a country that exerts regional leadership in scientific production in Latin America, but remains relatively peripheral to global science. This study examined the career trajectories and publication patterns of highly cited researchers based in Brazilian universities, using Web of Science and CV data. Our findings show a pattern of international mobility among the Brazilian highly cited researchers from the early stages of their careers. With few exceptions, engagement with the academic Anglosphere is central to their achievement of highly cited status, which is derived from co-authored publications with collaborators from the United States, the United Kingdom, and Australia in large teams.

Abstract Backgorund. While there has been a growth of research on health and the Syrian conflict, most such research covers Syrian refugees. There is limited information about the scope and focus of research on health and population inside Syria. While there are several systemtic and scoping literarure reviews of health of Syrian refugees, there has not been a sccoping review of research literature on health issues inside Syria. Methods. As part of a broader scoping review covering January 2011 to December 2019, we examined English-language conflict-related research papers that studied health issues inside Syria and focused on Syrians or those permanently resident in Syria. We classified research articles based on the major thematic areas studied. We abstracted bibliometric information, study characteristics, funding statements and reported key limitations and challenges of conducting research. To gain additional insights or data, we examined separately publications reporting field and operational activities as well as personal reflections and narrative accounts of first-hand experiences inside Syria. Results. Of 2,088 papers identified in the scoping review, 708 (34%) exclusively focus on health issues of Syrians inside Syria, of which 350 (49%) are conflict-related with. Of conflict-related publications, 89 (25%) are research papers. Annual volume of research increased over time, from one publication in 2013 to 27 publications in each of 2018 and 2019. Damascus is the most frequently studied governorate (n=33), followed by Aleppo (n=25). Papers used a wide range of research methodologies, primarily quantitative (n=68). The country of institutional affiliation(s) of first and last authors are Syria (n=30, 20 respectively), the United States (n=25, 19 respectively) or the United Kingdom (n=12, 10 respectively). Themes most covered were health status, health system and humanitarian assistance, response or needs (n=38, 32, 26 respectively). Thirty one publications presented field and operational activities and eight publications were reflections or first-hand personal accounts of experiences inside Syria. Authors encountered contextual, methodological and administrative challenges in doing research on health inside Syria. Conclusions. Although it is commonly stated that Syria is among the most documented of recent wars, our analysis shows that a relatively limited number of research studies focused on health or populations inside Syria have been published over the nine years of the conflict. Beyond the need to increase the volume of research, it is important to address the knowledge gaps identified in this review.

Potential Tool

Bibliometric analysis, a powerful tool for assessing trends in research output, was employed to analyze the evolution of hypertension research over a 20-year period. The analysis was based on 90 308 original articles and a citation analysis. The use of bibliometric as a potential tool for shaping research policy at the institution or country level was also explored. The number of published hypertension articles increased by 43.5% over the 20-year period. By contrast, the increase in the number of articles in all medical disciplines was 96%, and in the cardiovascular field was 64%. Of the 6 countries producing the largest number of articles, the United States was consistently the major contributor. There was a slight decrease from Japan, a slight increase from the United Kingdom, and relatively stable output from Germany and Italy over the study period. Output from China showed the strongest growth. The trends in Specialization Index and Category Normalized Citation Impact varied by country. In Russia, Poland, and Brazil, increases in output were greater for hypertension research than for medical research in general. The United Kingdom and Denmark had greater hypertension research output than the other countries. VOSviewer analysis showed an intensification of collaborations between countries and a shift, over 10 years, from 3 clusters towards 2 clusters. Such analysis may help to shape research policy at the country level and can be similarly performed for institutions. Historical changes in hypertension research can be monitored over decades if the same channels continue to be used for communication of scientific results.

Research activities and research output, in general, have increased, and keep increasing vastly, and so too is research on the polar regions including Svalbard in the Arctic. Major commercial publishers have built subscription-based services which present research literature for a fee. As Open Science and open access to literature and data is gaining momentum, there is a distinct need for powerful discovery tools that can harvest and present research literature and datasets in open access form - free of charge. Moreover, sharing of underlying data in open access form is becoming the new norm. So, to integrate research papers and datasets in the same search, helps speed up the discovery processes as well as fostering the transparency of research, and minimize duplication of fieldwork and experiments. Open Polar (https://openpolar.no/) is developed by UiT The Arctic University of Norway, and is a free to use discovery tool for open access publications and research data specifically targeting research output on the polar regions, across all subject areas, and irrespective of where the research originates. Through a carefully designed algorithm, Open Polar is extracting metadata (including URL to the landing page of the full text) from more than 4600 sources worldwide and making these accessible through a user-friendly search service - including an option to search via geolocations on a map, and with systematic search features. The algorithm used picks up relevant research located in the most remote content providers and sources. Thus, searching in Open Polar will result in records purely of relevance to the polar regions. In this contribution, we will present the many advantageous features of Open Polar, and show how Open Polar is supporting Open Science and research integrity-enhancing procedures, by enabling search and access to research data as well as research papers.

BACKGROUND Many previous papers have investigated most-cited articles or most productive authors in academics, but few have studied most-cited authors. Two challenges are faced in doing so, one of which is that some different authors will have the same name in the bibliometric data, and the second is that coauthors’ contributions are different in the article byline. No study has dealt with the matter of duplicate names in bibliometric data. Although betweenness centrality (BC) is one of the most popular degrees of density in social network analysis (SNA), few have applied the BC algorithm to interpret a network’s characteristics. A quantitative scheme must be used for calculating weighted author credits and then applying the metrics in comparison. OBJECTIVE This study aimed to apply the BC algorithm to examine possible identical names in a network and report the most-cited authors for a journal related to international mobile health (mHealth) research. METHODS We obtained 676 abstracts from Medline based on the keywords “JMIR mHealth and uHealth” (Journal) on June 30, 2018. The author names, countries/areas, and author-defined keywords were recorded. The BCs were then calculated for the following: (1) the most-cited authors displayed on Google Maps; (2) the geographical distribution of countries/areas for the first author; and (3) the keywords dispersed by BC and related to article topics in comparison on citation indices. Pajek software was used to yield the BC for each entity (or node). Bibliometric indices, including h-, g-, and x-indexes, the mean of core articles on g(Ag)=sum (citations on g-core/publications on g-core), and author impact factor (AIF), were applied. RESULTS We found that the most-cited author was Sherif M Badawy (from the United States), who had published six articles on JMIR mHealth and uHealth with high bibliometric indices (h=3; AIF=8.47; x=4.68; Ag=5.26). We also found that the two countries with the highest BC were the United States and the United Kingdom and that the two keyword clusters of mHealth and telemedicine earned the highest indices in comparison to other counterparts. All visual representations were successfully displayed on Google Maps. CONCLUSIONS The most cited authors were selected using the authorship-weighted scheme (AWS), and the keywords of mHealth and telemedicine were more highly cited than other counterparts. The results on Google Maps are novel and unique as knowledge concept maps for understanding the feature of a journal. The research approaches used in this study (ie, BC and AWS) can be applied to other bibliometric analyses in the future.

Abstract Background and purpose: The purpose of this study is to illustrate the evolution of cyberloafing research and identify the important papers in the development of cyberloafing knowledge. Methodology: We identify a total of 116 research papers from the Web of Science (WOS) database that were published in top journals during 1997-2019. We performed citation analysis, co-citation analysis, and main path analysis to identify the most influential authors, countries, and institutions in the development of cyberloafing research, and graphically map the relationships between them. Results: Cyberloafing research has progressed through three stages which we coin the emergent stage, the exploration stage, and the burgeoning stage. We also identify the relationships between articles and identify the distinct and significant knowledge streams, 16 influential papers that are seminal or highly sighted, and we identify the authors, institutions, and countries from which the research emerged. Researchers in the United States have produced the most research, followed by China, the United Kingdom, and Australia. The National University of Singapore produced the most research in our sample, and Vivian K. Lim of the National University of Singapore was the most influential author, anchored by her seminal piece on cyberloafing and organizational justice published in 2002. Conclusion: This study is, to our best knowledge, the first to examine the development of cyberloafing research using evidence-based analysis methods. It depicts the development of the cyberloafing literature and identifies significant streams that researchers can explore in the future. We conclude that future research should incorporate more direct measures of cyberloafing, examine individual consequences caused by too much cyberloafing, such as mental health.

Redistribution across individuals in a one-year-period framework is an empirically intensely studied question. However, a substantial share of annual redistribution might turn out to serve individual insurance in a longer perspective, reducing the level of actual redistribution across individuals. This paper investigates to what extent long-run redistribution diverges from annual redistribution in welfare states of different types. Exploiting panel data from the Cross-National Equivalent File (CNEF) for Australia, Germany, South Korea, Switzerland, the United Kingdom, and the United States, we find that welfare states like Germany that are assumed to engage in a high level of redistribution actually achieve relatively less redistribution between individuals in the long run than the United Kingdom or the United States. Regression results show that a higher share of elderly in a country is associated with more annual redistribution, but with less long-run redistribution between individuals. The results suggest that, in welfare states with aging populations, we might expect growing annual redistribution that, to a substantial extent, is in fact income smoothing for the elderly.

Background The COVID-19 pandemic, caused by the novel coronavirus SARS-CoV-2, has instigated immediate and massive worldwide research efforts. Rapid publication of research data may be desirable but also carries the risk of quality loss. Objective This analysis aimed to correlate the severity of the COVID-19 outbreak with its related scientific output per country. Methods All articles related to the COVID-19 pandemic were retrieved from Web of Science and analyzed using the web application SciPE (science performance evaluation), allowing for large data scientometric analyses of the global geographical distribution of scientific output. Results A total of 7185 publications, including 2592 articles, 2091 editorial materials, 2528 early access papers, 1479 letters, 633 reviews, and other contributions were extracted. The top 3 countries involved in COVID-19 research were the United States, China, and Italy. The confirmed COVID-19 cases or deaths per region correlated with scientific research output. The United States was most active in terms of collaborative efforts, sharing a significant amount of manuscript authorships with the United Kingdom, China, and Italy. The United States was China’s most frequent collaborative partner, followed by the United Kingdom. Conclusions The COVID-19 research landscape is rapidly developing and is driven by countries with a generally strong prepandemic research output but is also significantly affected by countries with a high prevalence of COVID-19 cases. Our findings indicate that the United States is leading international collaborative efforts.

Meta Analyses

Yoga research citations from 1948 to 2020 in PubMed were filtered and sorted in 10-year intervals to explore the occurrence and time frame of change in (1) the focus of research; (2) the number of randomized controlled trials (RCTs), systematic reviews (SRs), and meta-analyses (MAs); (3) health conditions researched for yoga as therapy; (4) journals with yoga research; and (5) the research on yoga from different countries. Publications on yoga between 1948 and 1970 (1.25%) focused on exceptional abilities of experienced yoga practitioners, apparently related to the spiritual goal of yoga; from 1971 to 2000 (6.87%), the focus was on yoga in health and therapy; and from 2001 to 2020 (91.88%), research publications on yoga increased and continued to focus on health and therapy, with fewer RCTs relative to the SRs and MAs on yoga in PubMed. Publications on yoga reported the following health conditions most often: from 1981 to 1990, (1) asthma, (2) stress, and (3) diabetes; from 1991 to 2000, (1) stress followed by (2) asthma, anxiety, and pain (all three with equal percentages); from 2001 to 2010, (1) depression, (2) stress, and (3) anxiety; and from 2011 to 2020, (1) stress, (2) depression, and (3) pain. The journals publishing research on yoga in PubMed have changed between 1971 and 2020 as follows: highly clinically relevant, broad-interest medical journals (1971 to 1990); journals relevant to mind-body interventions (1991 to 2000); and specialized journals for complementary and alternative medicine, particular branches of medicine, or research study designs (2001 to 2020). The highest yoga research output from 1971 to 1980 came from the United Kingdom (RCTs); from 1981 to 1990 the most research came from the United States (RCTs); from 1991 to 2000 the most research came from India (RCTs) and the United Kingdom (SRs); from 2001 to 2010 the most research came from the United States (RCTs, SRs) and the United Kingdom (MAs); and from 2011 to 2020 the most research came from the United States (RCTs, SRs, MAs). The trends in yoga research from this analysis reflect increased research related to yoga and health while suggesting areas for future research based on the strengths and gaps that have emerged.
