Relative Diversity Indices
Diversity indices are frequently applied in the form of ratios of absolute diversity to the maximum diversity possible. Regardless of whether the maximum diversity is defined to be limited by the number of species or by the number of individuals present, the resultant indices can be shown to possess mathematically undesirable qualities. All such indices, including equitability as measured by Pi...
متن کاملSamuel Stouffer and Relative Deprivation
This paper first offers a tribute to Samuel Stouffer (1900–1960), a major contributor to social psychology. He helped to establish probability surveys as a useful method for social science, led three major studies at midcentury, and introduced important new concepts and statistical methods. Thus, both conceptually and methodologically, he shaped modern social psychology. Second, the paper revit...
متن کاملRelative Deprivation and Intergroup Competition
Two experiments utilized a new experimental paradigm – the IPD-MD game – to study how relative deprivation at the group level affects intergroup competition. The IPD-MD game enables group members to make a costly contribution to either a within-group pool that benefits fellow in-group members, or a between-group pool, which, in addition harms out-group members. We found that when group members ...
متن کاملRelative Morse Indices, Fredholm Indices, and Group Velocities
We discuss Fredholm properties of the linearization of partial differential equations on cylindrical domains about travelling and modulated waves. We show that the Fredholm index of each such linearization is given by a relative Morse index which depends only on the asymptotic coefficients. Several strategies are outlined that help to compute relative Morse indices using crossing numbers of spa...
متن کاملInvestigating Modernism and Relative Deprivation in the Use of Cosmetics from the Students' Viewpoints
The main objective of this study was to investigate modernism and relative deprivation in girls` tendency in the use of cosmetics. Today, among the range of young girls we have seen excessive use of cosmetics and this requirement could make industry to become more sustainable. Existing theoretical literature and previous research claim to influence modern appliances as a social pattern that has...
