Differences in Collaboration Patterns across Discipline, Career Stage, and Gender
Fig 2
Gender differences in the propensity to co-author with prior collaborators.
Probability distribution of the fraction of total coauthors who are repeated for all females (orange) and males (purple) in the dataset with at least 10 publications. We exclude single-author publications. Orange and purple lines are kernel density estimation of the distributions for females and males with bandwidth given by Scott’s Rule [34]. We obtain p-values for the validity of the null hypothesis that the samples were drawn from the same distribution using the Kolmogorov-Smirnov test. For all disciplines, we find , where
and
are the average fr of the female and male faculty, respectively. Females have fr smaller than those of males, suggesting that, except for materials science, female faculty have a lower propensity than male faculty to repeat collaborations. Data for this figure are in S2 Data.
