Evolutionary Applications, 2019 Natural selection is inherently a multivariate phenomenon. The selection pressure on size (natural and artificial) and the age at which selection occurs is likely to induce evolutionary changes in growth rates across the entire life history. However, the

Mate selection—A selection for a handicap
Journal of Theoretical Biology, 1975 It is suggested that characters which develop through mate preference confer handicaps on the selected individuals in their survival. These handicaps are of use to the selecting sex since they test the quality of the mate. The size of characters selected in this way serve as marks of quality.

Measuring Selectivity-Corrected Gender Wage Gaps in the EU [PDF]
We investigate different techniques to assess the gender pay gap in five EU countries (France, Germany, Italy, Spain and United Kingdom), focusing on self-selection into market work.

A Selectivity Model for Fragmented Relations: Applied in Information Retrieval [PDF]
, 2004 New application domains cause today's database sizes to grow rapidly, posing great demands on technology. Data fragmentation facilitates techniques (like distribution, parallelization, and main-memory computing) meeting these demands. Also, fragmentation

An Unexpected Role of Local Selectivity in Social Promotion
A selection process and a hierarchical promotion system in a dynamic model are considered as in Harrington (1998) and Garcia-Martinez (2010), where agents are "climbing the pyramid" in a rank-order contest based on the "up or out" policy.

Understanding the chiral selectivity of gold nanotubes
, 2012 Based on first principles calculations, we show that both cohesive energy and string tension dictate the chiral selectivity of Au nanotubes (AuNTs). Moreover, they are linearly correlated with a new parameter that represents the bending degree of AuNTs ...
