Online distance learning emerged as a solution to continue with teaching and learning during the COVID-19 pandemic, which led to more scholarly publications in the field. The current study critically analyzed the publications using a range of scientometric techniques. The journal article was the predominant form of publication, and collaborative research work was preferred by scholars in this domain. The most-cited articles were published primarily in interdisciplinary journals. Most of the papers (43.64%) used quantitative methods, followed by qualitative methods (13.33%), and mixed methods (9.09%). A large proportion of publications (33%) did not indicate a research methodology. Visualizations of research show that the field has focused largely on remote teaching as a new term to depict online distance learning but has also covered a wider spectrum of issues in relation to teaching and learning, with an emphasis on technologies for teaching and learning, assessment, teacher capacities, and institutional preparedness.

Purpose: This study is an attempt to evaluating the growth of scientific literature in the domain of coronavirus and Covid-19 pandemic research based on scientometric indicators: prolific countries and relative citation impact (RCI); influential institutions; author analysis and network, h-index and citation; DC (degree of collaboration), CC (collaboration coefficient), MCI (modified collaboration index) in the subject domain of coronavirus and Covid-19 research.Design/methodology/approach: The authors adopted approaches to obtain the literature data from Scopus database from 2000 to 2020 by conducting a systematic search using keywords related to the studied subject domain. In total, 15,297 numbers of records were considered for the literature analysis considering the real significant growth of this subject domain. This study presented the scientometric analysis of these publications. Furthermore, statistical correlations have been used to understand the collaboration pattern. Visualization tool VOSviewer is used to construct the co-author network.Findings: The present study found that 53.57% (8,195) of the research documents published on the open-access platform. Journal of Virology was found to be most preferred journal by the researcher producing around 839(5.48%) articles. USA and China dominate in the research output, and the University of Hong Kong has produced the highest number of research paper 547(3.58%). A significant portion of the research documents are published in the subject domain of medicine (49.70%), followed by immunology and microbiology (35.72%), and biochemistry, genetics and molecular biology subject domains (22.32%). There has been an unparalleled proliferation of publications on COVID-19 since January 2020 and also a significant distribution of research funds across the globe.Research limitations/implications: The study exclusively examines 15,297 research outputs which have been indexed in the Scopus database from 2000 to 2020 (till 01 April 2020). Thus, documents published in any other different channels and sources which are not covered in Scopus are excluded from the purview of research.Practical implications: It will be beneficial for researchers and practitioners worldwide for understanding the growth of scientific literature in the coronavirus and COVID-19 and identifying potential collaborator.Originality/value: Considering the global impact and social distress due to the outbreak of COVID-19 pandemic, this study is significant in the present scenario for identifying the growth of scientific literature in this field and evolving of this domain of research around the globe. The research results are useful to identify valuable research patterns from publications and of developments in the field of coronavirus and COVID-19.

This comprehensive study focuses on analyzing the growth of research in the domain of ocean acidification using various bibliometric methods. Datasets were retrieved from Scopus databases using keywords pertaining to the subjects, and detailed analysis was made to understand the growth of literature, publication trends, authorship pattern, keywords, country-wise distribution, and leading institutes working in the subject domain of ocean acidification. The resultant data show that a significant portion (37.83%) of the research documents are published in open-access journals. The finding shows that 76.06% of the total publication has published in the last seven years (2013–2019). In the year 2017, research in this subject reached its peak with the highest number of publications 697 (12.54%). The top 15 journals published around 34.04% (1,891) of the entire research documents. GEOMAR Helmholtz Center for Ocean Research Kiel, Germany, has produced the highest number of research papers (5.42%) followed by Alfred Wegener Institute, Helmholtz Center for Polar and Marine Research, Germany (4.66%), and National Oceanic and Atmospheric Administration, the USA, with 4.39% of research documents. It has been found that Biogeosciences published by European Geosciences Union is the most preferred journal by researchers for publishing their work followed by Plos One covering around 215 (3.87%) papers and Marine Ecology Progress Series of 166 (2.99%) articles. A significant portion of the research documents are published in the sub-subject domain of Agricultural and Biological Sciences (55.31%), followed by Environmental Science (42.03%) and Earth and Planetary Sciences subject domains (37.99%). There has been an unparalleled growth of ocean acidification research during the last decade.

The study examined the relationship between e-learning usage, creativity, e-learning utility and academic performance among undergraduate (UG) and postgraduate (PG) students at Banaras Hindu University (BHU), India. The data from 480 students were collected using a cross-sectional survey design. Pearson correlation analysis was performed in order to investigate the association between the variables. The results revealed a significant positive correlation between time of use and academic performance (r = 0.294, p < 0.01). However, there was no significant correlation between time of use and the usability of e-learning in the attainment of learning outcomes. Furthermore, there was a negative correlation between time of use and creativity (r = −0.170, p < 0.01). The results indicate that educators ought to promote consistent utilization of e-learning platforms to enhance scholarly achievements. However, learners should exercise prudence in their usage, as an over-reliance on these platforms may impede their creativity. This study contributes to the existing body of knowledge regarding the impacts of e-learning on students' academic performance and creativity. Additionally, it offers instructing professionals and students who make use of e-learning platforms information that might be helpful to them.

In this study, we aimed to evaluate the trends of the most cited articles on ocean acidification using bibliometric techniques and to provide oceanographers and marine scientists a practical guide in assessing the most influential studies published on this domain. Scopus database is used to extract the literature, and detailed analysis was carried out to identify trends and significant of these studies. The top cited article received 3,183 citations and the least received 201, with a mean of 462 citations. These 100 most-cited papers originated from 34 different countries. The USA ranked top with the highest number of publications followed by Germany and Australia. The top five journals (Science, PNAS, Global Change Biology, Marine Ecology Progress Series, Nature) hold 40% of these influential studies. The thematic cluster analysis showed a composite characteristic of the research domain. The study indicated that a limited of the works focus on impact of ocean acidification on food web that needs to be urgently addressed by the oceanographic community. The study of the carbonate system in coastal, oceanic, and estuaries waters, and its ecological and biogeochemical implications are the emerging areas that required attention for the sustainability and maintaining a healthy balance of the marine ecosystem.
