Diversity and Interdisciplinarity:
How Can One Distinguish and Recombine Disparity, Variety, and Balance? 
<https://arxiv.org/abs/1803.09317>
>The dilemma which remained unsolved using Rao-Stirling diversity, 
>namely of how variety and balance can be combined into "dual concept 
>diversity" (Stirling, 1998, pp. 48f.) can be clarified by using Nijssen 
>et al.'s (1998) argument that the Gini coefficient is a perfect 
>indicator of balance. However, the Gini coefficient is not an indicator 
>of variety; this latter term can be operationalized independently as 
>relative variety. The three components of diversity--variety, balance, 
>and disparity--can thus be clearly distinguished and independently 
>operationalized as measures varying between zero and one. The new 
>diversity indicator ranges with more resolving power in the empirical 
>case.
