Multi-institutional authorship in genetics and high-energy physics

This study investigated the characteristics of multi-institutional authors and the academic impact of their articles in the fields of genetics and high-energy physics. The findings showed that the percentage of articles written by multi-institutional authors (87.3%) and the percentage of multi-institutional authors (27.8%) in genetics were higher than those (50.4% articles and 17.1% authors) in high-energy physics. Increasing trends were observed in the annual percentages of multi-institutional authors and their articles between 2008 and 2013 in both fields. Most multi-institutional authors were affiliated with two institutions. However, most multi-institutional authors in genetics were affiliated with two or more universities, whereas most multi-institutional authors in high-energy physics were affiliated with at least one university and one research institution. The academic impact of articles by multi-institutional authors was observed to be greater than that of other articles in high-energy physics (12.6 vs. 7.62 mean citations per article), and the opposite was observed in genetics (73.14 vs. 75.63 mean citations per article).
