Interdisciplinarity as diversity in citation patterns among journals: Rao-Stirling diversity, relative variety, and the Gini coefficient
作者：
Highlights：
• We modify Rao-Stirling diversity so that “balance” and “variety” are measured independently.
• We test the new indicator (DIV) for the set of journals in the Journal Citation Reports.
• The new indicator correlates with Betweenness Centrality significantly more than Rao-Stirling diversity.
• “Dual-concept” diversity is unnecessarily confusing; the Gini index can be used for measuring “balance”.
• A routine for the measurement of the various operationalizations of diversity (in any data matrix or vector) is made available online.
