Paradigm shift in Education Sector amidst COVID-19 to improve Online Engagement

The study aims to identify social, intellectual and conceptual structures along with key areas, contributors, current dynamics and suggest future research directions in the field of engagement with e-learning systems. An objective analysis of a sample of 358 articles taken from the Web of Science database, supported by subjective assessments based on the research focused on the integration of management into e-learning domain. Citations and PageRank metrics were used to identify the most influential papers along with most influential authors. To understand the intellectual structure of the research area, a co-citation network was developed. The study may help to explore effective ways of delivering education during a crisis, while also taking a sustainable approach to the promotion of education through online methods. By understanding the behavior of learners towards various forms of content delivery, policy makers at national level can develop a framework to implement it nationwide.

The Structure and Dynamics of Modern United States Federal Case Law

The structure and dynamics of modern United States Federal Case Law are examined here. The analyses utilize large-scale network analysis tools, natural language processing techniques, and information theory to examine all the federal opinions in the Court Listener database, containing approximately 1.3 million judicial opinions and 11.4 million citations. The analyses are focused on modern United States Federal Case Law, as cases in the Court Listener database range from approximately 1926–2020 and include most Federal jurisdictions. We examine the data set from a structural perspective using the citation network, overall and by time and space (jurisdiction). In addition to citation structure, we examine the dataset from a topical and information theoretic perspective, again, overall and by time and space.

Responsible Research and Innovation (RRI): Scientometric Analysis

Innovation and research in various fields should be done responsibly. In the last years, there is this responsibility towards different stakeholders. One of the most important stakeholders are the community and the society. In this context, the concept of social responsibility and social innovation has become very widespread. The purpose of this study was scientometric analysis of concepts in the field of responsible innovation and responsible research. R software has been used to achieve this purpose. In this study, by analyzing the information extracted from related articles (572 articles from Web of Science), the new concept of RRI and the network of researchers in this regard have been identified and analyzed. In this study, based on a systematic literature review (SLR) and scientometric methods, the evolution of the concept of “Responsible Research” and “Responsible Innovation” in the literature is investigated. Also, the selected articles identified by the SLR method from different textual dimensions regarding journals, collaboration network, co-citation network, collaboration worldmap, historical direct citation network, and emergence of new concepts are analyzed. The results of this study indicate the development of related concepts in the literature in recent years and indicate the need for further studies in this regard.

Citation Network Study on the Use of New Technologies in Neurorehabilitation

New technologies in neurorehabilitation is a wide concept that intends to find solutions for individual and collective needs through technical systems. Analysis through citation networks is used to search scientific literature related to a specific topic. On the one hand, the main countries, institutions, and authors researching this topic have been identified, as well as their evolution over time. On the other hand, the links between the authors, the countries, and the topics under research have been analyzed. The publications analysis was performed through the Web of Science database using the search terms “new technolog*,” “neurorehabilitation,” “physical therapy*,” and “occupational therapy*.” The selected interval of publication was from 1992 to December 2020. The results were analyzed using CitNetExplorer software. After a Web of Science search, a total of 454 publications and 135 citation networks were found, 1992 being the first year of publication. An exponential increase was detected from the year 2009. The largest number was detected in 2020. The main areas are rehabilitation and neurosciences and neurology. The most cited article was from Perry et al. in 2007, with a citation index of 460. The analysis of the top 20 most cited articles shows that most approach the use of robotic devices and brain–computer interface systems. In conclusion, the main theme was found to be the use of robotic devices to address neuromuscular rehabilitation goals and brain–computer interfaces and their applications in neurorehabilitation.

Mapping research on family business in tourism and hospitality: a bibliometric analysis

PurposeThis study aims to map the development of research on family business in tourism and hospitality and provides insights into the key contributors, key areas and current dynamics, and suggests future research directions in the field.Design/methodology/approachThis study uses the Web of Science (WoS) database to identify the 124 articles published in the theme. The study uses bibliometric indicators such as the co-citation network, word co-occurrence network to analyze the publication and citation structure using Science of Science (Sci2), OpenRefine, and Gephi.FindingsThe top authors, top journals and major themes are recognized using bibliometric techniques. The study identifies six keyword clusters: entrepreneurship, innovation, and empirical collaborating with tourism, hospitality, and family business. The country-wise collaboration indicates the lack of research in the eastern hemisphere of the world. The co-authorship shows studies shared among individuals of a few organizations. The trends from bibliographic coupling depict the evolution of research.Research limitations/implicationsThe scope of data collection for the network analysis is limited to the WoS. Incorporating papers from other databases might provide different network structures and insights.Originality/valueThe study is the first of its kind in the theme of family businesses in tourism and hospitality and will contribute to the literature by identifying future research directions.

Global mapping of research trends on antibacterial activity of green silver nanoparticles

Over the years, the quest for antibacterial agents from green nanoparticles has attracted great attention due to the global rise in the prevalence of multi-drug resistant bacteria. Although several studies on the antibacterial activity of plant-mediated silver nanoparticles have been documented, no bibliometric studies on the subject have been reported to date. As a result, the present study aimed to assess the global research trends on the antibacterial activity of green silver nanoparticles from 2000 to 2020. In the present study, we explored Science Citation Index Expanded (SCIE) to extract research articles written in English on the subject within the specified period. Two hundred and sixty-nine (269) eligible research articles were included in the bibliometric analysis and R-package “bibliometrix” was used to analyse the documents for annual scientific publications, authors’ impact, most relevant institutions, countries productivity, frequent words, co-occurrence network, co-citation network and authors/institutions/countries collaboration networks. Based on the analysis, the top three (3) authors, journals, institutions and countries were Kumar V (n = 5), Zangeneh MM (n = 5) and Oh BT (n = 4); King Saud University, Banaras Hindu University and Islamic Azad University; Journal of Cluster Science (n = 10), Applied Organometallic Chemistry (n = 8) and Microbial Pathogenesis (n = 8); India, Iran, and Korea. The study findings highlighted the gaps in a research collaboration that negate productivity. Therefore, we are optimitic that this study would enlighten researchers in the field about the research lapses and the need for research collaboration in future studies.
