A content analysis by bibliometry of the first ten years of the International Journal of Paleopathology

Sex estimation research trends in forensic anthropology between 2000 and 2022 in five prominent journals

In forensic anthropology, osteological sex estimation methods are continuously reevaluated and updated to improve classification accuracies. Therefore, to gain a comprehensive understanding of recent trends in sex estimation research in forensic anthropology, a content analysis of articles published between 2000 and 2022 in Forensic Science International, the Journal of Forensic Sciences, the International Journal of Legal Medicine, the American Journal of Biological Anthropology, and Forensic Anthropology, was performed. The main goals of this content analysis were to (1) examine trends in metric versus morphological research, (2) examine which areas of the skeleton have been explored, (3) examine which skeletal collections and population affinities have been most frequently utilized, and (4) determine which statistical methods were commonly implemented. A total of 440 articles were coded utilizing MAXQDA and the resulting codes were exported for analysis. Statistical analyses were conducted utilizing the Cochran-Armitage and Jonckheere-Terpstra tests for trends, as well as Fisher-Freeman-Halton tests. The results demonstrate that sex estimation research published in these journals has prioritized metric over morphological methods. Further, the most utilized skeletal regions continue to be the skull and pelvis, while the most popular classification statistics continue to be discriminant function analysis and logistic regression. This study also demonstrates that a substantial portion of research has been conducted utilizing U.S. and Europe-based collections and limited populations. Based on these results, future sex estimation research must continue exploring the use of long bones and other postcranial elements, testing newer methods of analysis, as well as developing population-inclusive methods.

The role of case studies in recent paleopathological literature: An argument for continuing relevance

OBJECTIVE

To critically examine the role that case studies play in recent paleopathological literature, by evaluating their frequency of publication, academic impact, and the public engagement they generate.

MATERIALS

Articles published in International Journal of Paleopathology between 2011 and 2018 (N = 377).

METHODS

Articles were coded as case studies, population studies, methodological studies, or reviews. Case studies were coded as cultural practices, differential diagnosis, historical, or methodological/theoretical. We utilized bibliometric analysis to assess academic impact and altmetric analysis to evaluate public engagement.

RESULTS

Case studies continue to be the most frequently published, but least frequently cited, article type. There are no significant differences in public engagement data between article types. Methodological/theoretical case studies have the most academic impact. Differential diagnosis case studies have the least academic impact and generate the least public engagement.

CONCLUSIONS

The case study genre includes a variety of approaches, some of which hold significant potential for contributing to the discipline of paleopathology and beyond.

SIGNIFICANCE

This study updates Mays' (2012b) citation analysis, pioneers the use of altmetric data to analyze public engagement with paleopathological publications, and identifies less productive approaches and areas of heightened relevance in the case study genre.

LIMITATIONS

Publications in only one journal were analyzed. Only one source was utilized for citation data (Google Scholar) and one source for altmetric data (PlumX).

SUGGESTIONS FOR FUTURE RESEARCH

Expanding the granular analysis of case studies piloted here to additional journals and/or citation indexes to enlarge the sample size and provide keener insights.
