This review has two purposes. First, we document the body of knowledge that has accumulated in Educational Management, Administration & Leadership over its five decades of publication. Second, we seek to identify the distinctive contributions of Educational Management, Administration & Leadership as a research journal in educational leadership and management. The review employed the bibliometric method in order to analyze the forms of corpus of 1438 articles published in Educational Management, Administration & Leadership between 1972 and the end of 2020. Bibliometric analyses used to document and assess the Educational Management, Administration & Leadership corpus included descriptive statistics, document citation and co-citation analysis, author co-citation analysis and keyword analysis. The review found that articles authored outside the UK have continued to grow as a proportion of the journal’s annual volume, thereby strengthening Educational Management, Administration & Leadership’s status as an ‘international educational leadership journal’. Document and keyword analyses found that ‘leadership’ has supplanted ‘administration’ and ‘management’ as the dominant driver in Educational Management, Administration & Leadership content since 2012. These analyses further affirmed the continuing strength of the journal’s conceptual contributions to the literature as well as its publication of a significant set of papers on shared forms of leadership. The review highlighted two areas for Educational Management, Administration & Leadership’s future development: further enhancing its citation impact and managing the growth of its international contributions.

Global Trends in Immunotherapy Research on Breast Cancer over the Past 10 Years.

In recent years, many studies have focused on the host immune system and its relationship with tumor progression in a variety of solid tumors, including breast cancer. This study investigates recent trends of immunotherapy research in breast cancer and compares the contributions of research from different regions, institutions, and authors. A search of breast cancer and immunotherapy studies that were published between 2010 and 2019—with different keyword combinations—was performed in the Web of Science database. Bibliometric data were collected for analysis. VOSviewer software was used to generate a figure for the keyword's co-occurrence network, so as to implement network visualization analysis. A total of 1,041 publications were identified. The United States and China contributed to approximately 50% of the publications, 336 and 208, respectively. Both countries drove the increase in publications after 2015. A paper entitled “Pembrolizumab in patients with advanced triple-negative breast cancer: Phase IB KEYNOTE-012 Study” that was published in the Journal of Clinical Oncology by Nanda et al. was the most cited (715 citations). The keywords found in this research were grouped into four clusters: “mechanism,” “vaccination,” “PD-L1,” and “chemotherapy.” The terms “tumor-infiltrating lymphocytes” and “PD-1/PD-L1” are among the latest hotspots, which mostly appeared in 2017. Author keyword analysis revealed that recent trends in breast cancer immunotherapy focus on the triple-negative breast cancer subtype and PD-1/PD-L1 immune checkpoint pathway and inhibitors. This study analyzed global trends in immunotherapy research on breast cancer over the past 10 years and provided insight into the features and research hotspots of the articles in this issue.

Academic Review and Perspectives on Robotic Exoskeletons.

Since the first robotic exoskeleton was developed in 1960, this research field has attracted much interest from both the academic and industrial communities resulting in scientific publications, prototype developments and commercialized products. In this article, to document the progress in and current status of this field, we performed a bibliometric analysis. This analysis evaluated the publications in the field of robotic exoskeletons from 1990 to July 2019 that were retrieved from the Science Citation Index Expanded database. The bibliometric analyses were presented in terms of author keywords, year, country, institution, journal, author, and the citation. Results show that currently the United States has taken the leading position in this field and has built the largest collaborative network with other countries. The Massachusetts Institute of Technology (MIT) made the greatest contribution to the field of robotic exoskeleton investigations in terms of the number of publications, average citations per publication and the h-index. In addition, the Journal of NeuroEngineering and Rehabilitation ranks first among the top 20 academic journals in terms of the number of publications related to robotic exoskeletons during the period investigated. Author keyword analysis indicates that most research has focused on rehabilitation robotics. Biomedical engineering, rehabilitation and the neurosciences are the most common disciplines conducting research in this area according to the Web of Science (WoS). Our study comprehensively assesses the current research status and collaboration network of robotic exoskeletons, thus helping researchers steer their projects or locate potential collaborators.

Past and emerging topics related to electronic waste management: top countries, trends, and perspectives.

A bibliometric analysis was performed to assess historical and recent research trends regarding e-waste studies from 1998 to 2018. Documents related to e-waste were identified from the Clarivate Analytics Web of Science© (WoS) database, and a total of 3311 academic articles was retrieved. The analysis was performed from four main aspects: (1) publication activity by year, by WoS category, and by geographic distribution; (2) journals; (3) most-cited papers; and (4) top 10 countries and author keyword analysis. The number of publications concerning e-waste issues has increased substantially over the last 20years, especially in the environmental science category, and more than a third of the publications were produced in China (1181 records). Waste Management and Environmental Science & Technology were the most sought-after journals for disseminating the results. Studies related to "e-waste flow analysis," "recycling," "recovery of precious metals," and "risk assessment of recycling areas" have been the most common for several years. The analysis of keywords suggested that there are many topics on electronic waste and that each country has presented a different focus of research. Overall, the bibliometric analysis proved to be an efficient tool with which to monitor historical and current research trends and to evaluate the sheer volume of currently existing scientific literature on e-waste topics.

An author keyword analysis for mapping Sport Sciences.

Scientific production has increased exponentially in recent years. It is necessary to find methodological strategies for understanding holistic or macro views of the major research trends developed in specific fields. Data mining is a useful technique to address this task. In particular, our study presents a global analysis of the information generated during last decades in the Sport Sciences Category (SSC) included in the Web of Science database. An analysis of the frequency of appearance and the dynamics of the Author Keywords (AKs) has been made for the last thirty years. Likewise, the network of co-occurrences established between words and the survival time of new words that have appeared since 2001 has also been analysed. One of the main findings of our research is the identification of six large thematic clusters in the SSC. There are also two major terms that coexist ('REHABILITATION' and 'EXERCISE') and show a high frequency of appearance, as well as a key behaviour in the calculated co-occurrence networks. Another significant finding is that AKs are mostly accepted in the SSC since there has been high percentage of new terms during 2001–2006, although they have a low survival period. These results support a multidisciplinary perspective within the Sport Sciences field of study and a colonization of the field by rehabilitation according to our AK analysis.

Webometric Analysis of Linkages between Environment Related Researchers and Institutes in Sri Lanka

Every scientist, research Institute and all research publications are connected to one another by means of affiliations, co-authorships and citations. The objective of the present study was to visualize linkages among researchers and institutes in environment related publications in Sri Lanka, aiming to identify special patterns and trends. This Webometric and Bibliometric study had three main sections: co-citation analysis, co-authorship analysis, and hyperlink analysis. In addition, an author keyword analysis and a co-citation analysis was conducted to identify different areas within the environmental science field and their relative popularity. The analysis was conducted using data gathered from the abstract and citation database “Scopus”, which were published during the 10-year time period from 2006 to 2015.VOSviever was used to generate maps. Gathered data revealed that a total of 10,367 authors were involved in environment related publications. It has been observed that even though the study was conducted using Sri Lankan publications, collaboration between foreign and domestic scientists was higher than Sri Lankan scientists themselves. From subject related linkages within environment related publications, the study revealed 24 different subject areas of interest among scientists based on author keyword analysis and co-citation analysis. Out of that 13.3% and 11.9% of the publications are related to ‘Ecology’ and ‘Agriculture’ respectively. It was found that 45 institutes were involved in environment related publications. Analysis revealed that 42.0% of total citation links (Citation Analysis) and 30.9% of total co-authorship links (Co-authorship Analysis) belong to the University of Peradeniya. Citation analysis of authors revealed 3,116 authors (30.1%) with at least one citation link, and 7,251 (69.9%) authors with zero citation links. Highest (10.1%) non-domestic citation links were with United States scientists. Followed by India (6.5%) and Australia (6.3%).Hyperlink analysis revealed a low connectivity between institute web domains with only 11 out of 45 domains that contain more than 10 outgoing ‘url citations’ to one another. It was evident that the research output in subject areas such as Wildlife Management, Climate Change and Waste Management are much lower in comparison. These institutes and researchers need to keep a much higher web activity and connectivity in order to obtain a better online visibility.

A bibliometric analysis of eutrophication literatures: an expanding and shifting focus.

This paper examined the eutrophication literatures from 1998 to 2015 using bibliometric techniques basing on the database of Science Citation Index. Bibliometric techniques, social network analysis, and mapping knowledge domains in this paper were used. The results revealed that article was the most used document type accounting for 94.79% (14,006) of the records. With the rapid development of eutrophication domain after 2004, the annual article publishing amount also grew notably in each country, with the list of US tops. International cooperation was not enough to compare with that between institutions. An author keyword analysis showed that "phosphorus," "nutrients," "nitrogen," "water quality," "phytoplankton," and "sediment" were the most popular keywords. And it was also found that climate change, life cycle assessment, and chlorophyll a appear with high frequency in recent years, indicating that the eutrophication mechanism analysis might turn from uni-factor microresearch to multi-factor macroresearch, and the eutrophication management research tends to be whole-process management research. In addition, the future focuses of research directions, including (1) eutrophication and its ecosystem response, (2) eutrophication management, (3) eutrophication and climate change interactions, (4) eutrophication monitoring and forecast, and (5) ecological restoration of eutrophication. These findings are useful for the future endeavor of eutrophication academic research.

Mapping of drinking water research: A bibliometric analysis of research output during 1992–2011

A bibliometric analysis based on the Science Citation Index Expanded from the Web of Science was carried out to provide insights into research activities and tendencies of the global drinking water from 1992 to 2011. Study emphases included performance of publication covering annual outputs, mainstream journals, Web of Science categories, leading countries, institutions, research tendencies and hotspots. The results indicated that annual output of the related scientific articles increased steadily. Water Research, Environmental Science & Technology, and Journal American Water Works Association were the three most common journals in drinking water research. The USA took a leading position out of 168 countries/territories, followed by Japan and Germany. A summary of the most frequently used keywords obtained from words in paper title analysis, author keyword analysis and KeyWords Plus analysis provided the clues to discover the current research emphases. The mainstream research related to drinking water was water treatment methods and the related contaminants. Disinfection process and consequent disinfection by-products attracted much attention. Ozonation and chlorination in disinfection, and adsorption were common techniques and are getting popular. Commonly researched drinking water contaminants concerned arsenic, nitrate, fluoride, lead, and cadmium, and pharmaceuticals emerged as the frequently studied contaminants in recent years. Disease caused by contaminants strongly promoted the development of related research.
