ABSTRACT
PurposeUsing science mapping analysis approach and co-word analysis, the present study explores and visualizes research fields and thematic evolution of the coronavirus. Based on this method, one can get a picture of the real content of the themes in the mentioned thematic area and identify the main minor and emerging themes.Design/methodology/approachThis study was conducted based on co-word science mapping analysis under a longitudinal study (from 1988 to 2020). The collection of documents in this study was further divided into three subperiods: 1988–1998, 1999–2009 and 2010–2020. In order to perform science mapping analysis based on co-word bibliographic networks, SciMAT was utilized as a bibliometric tool. Moreover, WoS, PubMed and Scopus bibliographic databases were used to download all records.FindingsIn this study, strategic diagrams were demonstrated for the coronavirus research for a chronological period to assess the most relevant themes. Each diagram depended on the sum of documents linked to each research topic. In the first period (1988–1998), the most centralizations were on virology and evaluation of coronavirus structure and its structural and nonstructural proteins. In the second period (1999–2009), with due attention to high population density in eastern Asia and the increasing number of people affected with the new generation of coronavirus (named severe acute respiratory syndrome virus or SARS virus), publications have been concentrated on "antiviral activity.” In the third period (2010–2020), there was a tendency to investigate clinical syndromes, and most of the publications and citations were about hot topics like "severe acute respiratory syndrome,” "coronavirus” and "respiratory tract disease.” Scientometric analysis of the field of coronavirus can be regarded as a roadmap for future research and policymaking in this important area.Originality/valueThe originality of this research can be considered in two ways. First, the strategic diagrams of coronavirus are drawn in four thematic areas including motor cluster, basic and transversal cluster, highly developed cluster and emerging and declining cluster. Second, COVID-19 is mentioned as a hot topic of research.
ABSTRACT
Recent interest in multiple sclerosis research warrants literature analysis to evaluate the current state of the discipline and new research domains. This bibliometric review summarised the research trends and analysed research areas in multiple sclerosis over the last decade. The documents containing the term 'multiple sclerosis' in the article title were retrieved from the Scopus database. We used Harzing's Publish or Perish and VOSviewer for citation analysis and data visualisation, respectively. We found a total of 18,003 articles published in journals in the English language between 2012 and 2021. The emerging keywords identified utilising the enhanced strategic diagram were 'covid-19', 'teriflunomide', 'clinical trial', 'microglia', 'b cells', 'myelin', 'brain', 'white matter', 'functional connectivity', 'pain', 'employment', 'health-related quality of life', 'meta-analysis' and 'comorbidity'. This study demonstrates the tremendous growth of multiple sclerosis literature worldwide, which is expected to grow more than double during the next decade especially in the identified emerging topics.

Purpose: Mobile payment (m-payment) has existed for over 25 years;however, there is no standard framework to guide scholars and practitioners in advancing m-payment research in the digital accelerated era. With this, this study aims to develop an m-payment framework and to analyse the evolution of m-payment research from 1997 to 2021. These were achieved by identifying the motor themes, basic and transversal themes, the emerging/declining themes and the highly developed but isolated themes. In addition, the publication trends of m-payment research were also identified. Design/methodology/approach: A total of 1,999 articles of m-payment were identified from the Scopus database and 8,125 keywords were grouped into 483 word groups for the co-word analysis. Thematic networks were generated based on density and centrality. Performance analysis was performed on the themes of the four quadrants in the strategic diagrams. The m-payment framework was then developed based on the evolution map and a practical guide was built from the framework. Findings: The m-payment framework consists of four dimensions, namely behaviour, technology, risk, and context. Some themes were declining while at the same time, m-payment remains strongly relevant and can stand the test of time. Several new themes have emerged in the 2013–2021 sub-periods. Research limitations/implications: This study is limited in that the study only investigates from the context of m-payment. Practical implications: This study has provided a research framework (i.e. the m-payment framework) with a practical guide for scholars and practitioners to refer to, thus enabling them to embark on future studies without any hassle. The m-payment framework was developed based on empirical data using science mapping analysis of 1,999 articles. Social implications: The proposed m-payment research framework contributes towards more understanding of m-payment ten, usage amongst consumers and thus will help to reduce the rate of COVID-19 infection because m-payment is a contactless payment. Hence, the study may help in creating a safer and healthier society amid the unprecedented pandemic. Originality/value: This study developed the m-payment framework based on empirical co-word analysis. A practical guide to extending the framework is also provided to guide the scholars and practitioners. Moreover, the evolution map for m-payment was created to understand the evolution of m-payment research. Practitioners may conduct market studies to unveil the factors that contribute to consumers' behaviours in m-payment in order to gain more understanding of the reasons behind their behaviours. © 2022, Emerald Publishing Limited.
