To gain insight into the trend of bacterial nanocellulose research, a bibliometric analysis was performed using the Science Citation Index Expanded database from 2005 to 2020. The study concentrated on the publication’s performance in terms of annual outputs and citations, mainstream journals, categories of the Web of Sciences, leading countries, prominent institutions, and trends in research. Current research priorities and future trends were analyzed after summarizing the most commonly used keywords extracted from words in the paper title analysis, authors’ keyword analysis, and KeyWords Plus. The findings revealed that the annual output in the form of scholarly articles on bacterial nanocellulose research steadily increased during the first quartile of the study period, followed by a very rapid increase in the last five-years of the study. Increasing mechanical strength would remain the main future focus of bacterial nanocellulose research to create its scope in different field of applications.

Blockchain technology has gained widespread utility, particularly in the field of finance due to the popularity of bitcoin. There are other areas such as energy trade and securities market, which have evolved due to blockchain. These fields are new and building regulations and architecture to enhance their functionality. There are studies on blockchain finance and this paper aims to summarize a few of the pathbreaking studies and guide future research in this field. This paper reviews 77 journal publications related to blockchain from 2018 to 2021 available in the Science Citation Index (SCI) and Social Science Citation Index (SSCI) database. The selected papers have been grouped into 10 categories. This overview indicates that research in blockchain finance needs to focus on developing better privacy and security mechanism as well as better regulations regarding financial transactions not only to benefit from “Initial Coin Offerings”, but also to diversify investor’s risk.

Abstract Objective The objective of this scoping review is to understand what is known in relation to geographical inequalities in COVID-19 mortality. Introduction: COVID-19 has occurred against a backdrop of existing social and economic inequalities in health. The impact of the pandemic has been examined across various intersections of health inequalities such as age, gender, ethnicity, and occupation. However, spatial inequalities have been less explored. Therefore, this review aims to identify and synthesise what is known on geographical inequalities in COVID-19 mortality globally. Inclusion criteria: Following standard scoping review methodology the inclusion criteria will be guided by Population, Concept, Context (PCC). Population: children and adults (all ages); Concept: Area-level inequalities in COVID-19 mortality; Context: any country, at any level (neighbourhood, town, city, municipality, region). Any published, peer-reviewed study written in English that focuses on all three elements of the PCC inclusion criteria will be included. Methods Searches will be conducted in (host sites given in parentheses) Medline (Ovid), Embase (Ovid), Science Citation Index Expanded and Social Science Citation Index (Web of Science) and limited to dates ranging from 1st January 2020 to December 31st 2021. Reference lists of all relevant papers will be searched for additional studies. All titles and abstracts will be screened in Rayyan. Primary studies focusing on COVID-19 mortality rates disaggregated by any measure of area-level deprivation will be selected for full text review. Data relating to study design, population, location, outcomes, and results by deprivation will be extracted using standardised extraction forms. Identified papers meeting the inclusion criteria will be tabulated, synthesised thematically and a narrative constructed to describe the evidence base of geographical inequalities in COVID-19 mortality.

Media fragmentation represents new challenges for product placement strategies to become an increasingly effective way to reach consumers and non-users. In this frame, this paper has been developed with three main objectives: (i) to carry on a performance analysis to measure the visibility/impact of the scientific product in product placement (most cited authors, journals, and themes), (ii) to visually present the scientific structure by topics of research in product placement as well as its evolution to identify future research lines, and (iii) to compare both objectives in generic journals and specific communication ones. To this end, the resources in the Web of Science Citation Index were used. Scimat software was applied on a sample of 694 indexed papers from 1992 to 2021 containing “product placement” with 8,521 global citations (176 of the papers were indexed in communication journals with 3,190 citations). Our results show that MEMORY is a key motor theme—the future of research tends to new themes in the communication field (i.e., ATTITUDES/BEHAVIORS or VIRTUAL). Three industries have been key: alcohol, tobacco, and food. This research adds value to previous analysis as long as we have included: (i) a multidisciplinary approach; (ii) an unfolded analysis focusing strictly on communication journals; and (iii) a longitudinal analysis to compare different periods showing dynamic scientific maps.

The purpose of this scientometric study is to analyze the multiple sclerosis research in Science Citation Index-Expanded from 1992 to 2019 in order to determine the top features, trends, and topics. Articles related to multiple sclerosis in the section of title, abstract, keywords, and KeyWords Plus were retrieved from the Science Citation Index-Expanded and analyzed based on various indicators and characteristics. There was a significant increase in the number of articles from 408 in 1992 to 2756 in 2019. A sum of 42,112 articles related to multiple sclerosis has been published in 3,032 journals, which were classified among the 131 Web of Science categories. The top two categories were clinical neurology and neurosciences. Multiple Sclerosis Journal published the most articles. Articles published in the Neurology journal also had the highest citation per publication. Most of the articles were in English, while 23 other languages were used in the articles. Articles in Japanese and English with 7 and 6.9 authors have a higher average of authors than articles in other languages. English language articles received more citations than articles in other languages. The frequency of used keywords in title, abstract, author keywords, and KeyWords Plus analysis showed that “Therapy”, “disability”, “neurodegeneration”, “demyelination” and “MRI” show an increasing trend in the multiple sclerosis articles. The result of this study can help the policy makers and researchers realize the panorama of multiple sclerosis research and design future research.

Purpose This paper aims to analyse the research contributions of the Kingdom of Saudi Arabia in the field of applied linguistics (AL) indexed in the Web of Science core collection for the period between 2011 and 2020. Design/methodology/approach The author searched key terms in the Social Science Citation Index and Science Citation Index Expanded categories that publish documents in AL. The author compiled the data, classified these documents according to their research focus and investigated different metrics such as keywords analysis, citation analysis, overseas collaboration and productivity over authors, institutions and sources by using VOSviewer and Excel sheet. Findings Results found that publications in Saudi Arabia have tremendously increased around three times in the years 2016–2020 than before. As unexpected, highly cited researchers, sources and institutions for the social science and arts and humanities disciplines were higher than the scientific disciplines that investigated linguistic issues such as neurology, audiology and computer science. The area of language teaching and learning was the most researched area in which the highly cited author, journals and keywords analysis metrics occurred within its scope. The highly cited articles were those that collaborated with the world contributing authors and acted as corresponding authors. Originality/value The study contributes to the body of literature of AL which shares other categories that investigated language as a central issue. The study provides a fine-grained picture about the research productivity of AL in scientific and social science categories in Saudi Arabia.

The article represents the bibliometric analysis of the documentary corpus devoted to studying the Semipalatinsk nuclear test site selected of the database Russian Science Citation Index. It shows the publication dynamics over a thirty-year period, the specific structure of the documentary corpus; revels that the documents are thematically structured as follows: research of the medical and biological consequences of radiation exposure (genetic consequences of ionizing radiation exposure; diseases induced by radiation exposure); assessment of the consequences of nuclear tests for the environment (environmental monitoring, radiation situation, pollution of separate environment elements), historical and socio-legal aspects of investigating the test site activity consequences.
