Endogamy in scientific journals: analysis of authorship links in articles from journals in Santa Catarina

Authorship SCIMAGO INSTITUTIONS RANKINGS

ABSTRACT

Introduction: This research addresses authorial endogamy in journals affiliated with universities in Santa Catarina, Brazil.

Objectives: The general objective is to investigate authorial endogamy in scientific journals published by universities in Santa Catarina. The specific objectives are: a) to identify the average rate of authorial endogamy by publishing institution; b) to analyze endogamy rates by evaluation stratum; c) to relate endogamy rates to journal indexing; and d) to discuss endogamy rates concerning the areas of knowledge defined by CAPES.

Methodology: The research is exploratory and descriptive, with a quantitative approach, utilizing bibliographic and documentary techniques. The study sample consists of 117 journal titles. The institutional affiliations of the authors of the following types of documents were analyzed: essays, review articles, research articles, and data articles published in these journals in 2023. The analyzed variables included: the number of articles, the number of articles with endogenous authorship, the journal’s year of creation, its CAPES Qualis ranking, and its presence in indexing databases such as SciELO, SCOPUS, WoS, and DOAJ.

Results: The average endogamy rate in universities in Santa Catarina is 15%, but four institutions exceed this value: UNIARP (21.43%), UNIVILLE (22.73%), UNC (39.07%), and UNESC (54%). Regarding journal rankings, most titles fall within stratum A, totaling 62 journals (53%).

Conclusion: Tolerance for endogamy is related to the field of knowledge and the profile of the journal, as well as the organizational culture of its editors and editorial team members, who establish the journal’s guidelines and define its evaluation criteria.
