The 100 Leading Contributors to English-Language Gerontological Journals: An International Study of Scholarly Impact

The two aims of this study were to: 1) identify the 100 most impactful contributors to English-language gerontological journals, and 2) map their respective disciplinary affiliations to help illuminate the perspectives shaping gerontological discourse. Toward that end, we conducted a secondary data analysis of a publicly available database of the world's leading scientists. After extracting all scientists in the gerontological category, we rank ordered them according to a composite measure of scholarly impact that controls for self-citations and author order while also calculating other bibliometric statistics. Disciplinary affiliations were assigned based upon the Classification of Instructional Programs codes developed by the National Center for Education Statistics at the United States Department of Education. The results reveal the mean contributor to the gerontological literature published 241.15 (SD = 203.95) papers and - after correcting for self-citations - had an h-index of 50.05 (SD = 25.00), and an hm-index 23.67 (SD = 7.50). A diverse array of professional affiliations characterized the contributors with a plurality being located in the health professions category, followed by the biological and biomedical science, and social sciences categories. The results reveal that gerontology is home to some of the world's leading scientists. Leveraging their expertise can help advance the field's collective knowledge development.

Identifying the Leading Global Contributors to Scholarship in Religion Journals: A Bibliometric Study

This study identified the 100 most impactful global contributors to religion journals and mapped their respective disciplinary affiliations. To conduct this investigation, we performed a secondary data analysis of a Scopus-derived database featuring the world's leading scientists. The mean contributor published 51.93 papers, had an h-index of 13.57, and an hm-index 11.50. Most contributors were located in the USA with the most common disciplinary affiliations being religion, non-specialized (n = 22), sociology, non-specialized (n = 21), sociology of religion (n = 20), and theology (n = 11). The results reveal that religion discourse is populated by some of the leading scholars in the world. Leveraging their expertise can help advance the field's knowledge development.
