This paper presents the landscape of research on airborne microplastics and nanoplastics (MPs/NPs) according to the bibliometric analysis of 147 documents issued between 2015 and 2021, extracted from the Web of Science database. The publications on airborne MPs/NPs have increased rapidly from 2015 onwards, which is largely due to the existence of funding support. Science of the Total Environment is one of the prominent journals in publishing related papers. China, England, the USA, and European Countries have produced a significant output of airborne MP/NP research works, which is associated with the availability of funding agencies regionally or nationally. The research hotspot on the topic ranges from the transport of airborne MPs/NPs to their deposition in the terrestrial or aquatic environments, along with the contamination of samples by indoor MPs/NPs. Most of the publications are either research or review papers related to MPs/NPs. It is crucial to share the understanding of global plastic pollution and its unfavorable effects on humankind by promoting awareness of the existence and impact of MPs/NPs. Funding agencies are vital in boosting the research development of airborne MPs/NPs. Some countries that are lacking funding support were able to publish research findings related to the field of interest, however, with lesser research output. Without sufficient fundings, some impactful publications may not be able to carry a substantial impact in sharing the findings and discoveries with the mass public. [ABSTRACT FROM AUTHOR]

Granger causality provides a framework that uses predictability to identify causation between time series variables. This is important to policymakers for effective policy management and recommendations. Granger causality is recognized as the primary advance on the causation problem. The objective of this paper is to conduct a bibliometric analysis of Granger causality publications indexed in the Web of Science database. Harzing's Publish or Perish and VOSviewer were used for performance analysis and science mapping. The first paper indexed was published in 1981 and there has been an upward trend in the annual publication of Granger causality studies which are shifting towards the areas of environmental science, energy, and economics. Most of the publications are articles and proceeding papers under the areas of business economics, environmental science ecology, and neurosciences/neurology. China has the highest number of publications while the United States has the highest number of citations. England has the highest citation impact. This paper also constructed country co-authorship, co-analysis of cited references, cited sources, and cited authors, keyword co-occurrence, and keyword overlay visualization maps.

This research is an attempt to examine the recent status and development of scientific studies on the use of machine learning algorithms to model air pollution challenges. This study uses the Web of Science database as a primary search engine and covers over 900 highly peer-reviewed articles in the period 1990–2022. Papers published on these topics were evaluated using the VOSViewer and biblioshiny software to identify and visualize significant authors, key trends, nations, research publications, and journals working on these issues. The findings show that research grew exponentially after 2012. Based on the survey, "particulate matter" is the highly occurring keyword, followed by "prediction". Papers published by Chinese researchers have garnered the most citations (2421), followed by papers published in the United States of America (2256), and England (722). This study assists scholars, professionals, and global policymakers in understanding the current status of the research contribution on "air pollution and machine learning" as well as identifying the relevant areas for future research.

This work aims to present an overview of the factors, attributes or behaviour of entrepreneurial leadership research with a comprehensive bibliometric analysis. 1,594 articles, dated from 2000 to December 2020, were taken from the main Web of Science database collection and analysed with a bibliometric study using performance analysis and scientific mapping methods. To evaluate the importance, quality and impact of publications, indicators like productivity, citations or h-index were used to obtain an analysis of trends and advances on the most relevant publications, authors, journals and countries. Research was complemented by scientific mapping obtained through co-citations, bibliographic couplings, co-occurrences and co-authorships. The results show that the trend of publications has considerably increased since 2015, and the highest productivity was recorded in 2020. The USA and England are two of the most influential publishing countries, although the network analysis reveals cooperation with different countries. The most productive journal is Sustainability and the most influential is the Journal of Business Venturing. This systematic mapping of the field helps to illustrate the research evolution over time, identifies areas of current interest for use in theoretical and empirical frameworks, and provides a solid roadmap for future research. The keyword analysis reveals that the term “entrepreneurial leadership” started to be used in its own right from around 2018 on average. [ABSTRACT FROM AUTHOR]

Today, innovation that results from technological improvements and developments directly affects societies and social life. This interaction led to the emergence of the concept of social innovation. Social innovation is the process of developing and implementing effective solutions to social and environmental problems in order to support social progress. The aim of the study is to investigate the researches about the concept of social innovation, which has come to the fore in recent years, by using bibliometric analysis method. For this purpose, the Web of Science database is scanned using the concept of social innovation between 2010-2019 and a total of 579 publications are reached. Publications are visualized by VOSviewer mapping method. In the end of the analysis of these studies, it is seen that the most frequently used keyword is "social innovation", the most published and most co-authored author is Antonius Schröder, and the most cited author is Frances R. Westley. In addition, it is among the findings that Spain is the most broadcasting country (90 broadcasts) and England is the country with the most citation (915 citations). [ABSTRACT FROM AUTHOR]
