Quantifying aerosol mixing state with entropy and diversity measures

“…Other important research questions include 120 the sources of diversity (Tsimring et al, 1996;De'ath, 2012), extensions of diversity to include a concept of species distance Chao et al (2010); Leinster and Cobbold (2012);Feoli (2012);Scheiner (2012), and techniques for measuring diversity (Chao and Shen, 2003;Schmera and Podani, 2013;125 Gotelli and Chao, 2013), despite the well-known difficulties in estimating entropy in an unbiased fashion (Harris, 1975;Paninski, 2003). Beyond ecology, the study of diversity is also important in economics (Garrison and Paulson, 1973;Hannah and Kay, 1977;Attaran and Zwick, 1989;Malizia 130 and Ke, 1993;Drucker, 2013), immunology (Tsimring et al, 1996), neuroscience (Panzeri and Treves, 1996;Strong et al, 1998), and genetics (Innan et al, 1999;Rosenberg et al, 2002;Falush et al, 2007). This paper is organized as follows.…”

Is diversification a Strategic Advantage? The Example of Automotive Components in the Czech Republic

“…The level of diversifi cation can be measured by a wide range of statistical tools. Entropy, for instance, is a useful measure for examining industrial diversity either among regions or for a particular region over time (Attaran, 1989). Many studies apply the opposite approach by measuring the level of industry or portfolio concentration and thus deriving the reverse value of its diversifi cation.…”

Conflict and Conflict Management with Interdependent Instruments and Asymmetric Stakes, (The Good-Cop and the Bad-Cop Game)

“…Entropy has been also proposed as a measure of competitiveness and diversification in market structure: see Attaran and Zwick (1989) and Horowitz and Horowitz (1968). 10 The form adopted here is the one presented in Campiglio (1999), ch.4, andLiossatos (2005).…”
