Recent research identifies stochastic dominance as critical for understanding the relationship between network structure and diffusion. This paper introduces the concept of stochastic dominance, explains the theory linking stochastic dominance and diffusion, and applies this theory to a number of diffusion studies in the literature. The paper illustrates how the theory connects observations fro...

One of the first patterns noticed by geneticists was that mutations are almost always recessive to their wild-type alleles. Several explanations of this striking pattern have been offered. The two most influential are Fisher's theory--which argues that dominance results from natural selection against recurring deleterious mutations--and Wright's theory--which argues that dominance results from ...

By incorporating both majorization theory and stochastic dominance theory, this paper presents a general theory and a unifying framework for determining the diversification preferences of risk-averse investors and conditions under which they would unanimously judge a particular asset to be superior. In particular, we develop a theory for comparing the preferences of different convex combination...

Dominance constraints for nite tree structures are widely used in several areas of computational linguistics including syntax, semantics, and discourse. In this paper, we investigate algorithmic and complexity questions for dominance constraints and their rst-order theory. We present two NP algorithms for solving dominance constraints, which have been implemented in the concurrent constraint pr...

The modeling of complex risk situations imposes the existence of multiple ways to represent the risk and compare the risk situations between them. In probabilistic models, risk is described by random variables and risk situations are compared by stochastic dominance. In possibilistic or credibilistic models, risk is represented by fuzzy variables. This paper concerns three indicators of dominan...

Three theories of apical dominance, direct, diversion, and indirect, were proposed in the 1930s to explain how auxin synthesized in the shoot apex might inhibit axillary bud outgrowth, and thus shoot branching. The direct and diversion theories of apical dominance have been investigated in detail, and they are replaced with the current auxin transport canalization and second messenger theories,...

This chapter reviews the last 15 years of research inspired by social dominance theory, a general theory of societal group-based inequality. In doing so, we sketch the broad outlines of the theory and discuss some of the controversies surrounding it, such as the ‘‘invariance hypothesis’’ regarding gender differences in social dominance orientation (SDO) and the effect of social context on the e...
