the micro-segregation in binary al-cu alloys containing 2.2, 3.7, and 4.8 wt.% copper was investigated by differential thermal analysis (dta) and numerical modeling. for this purpose, the alloys were melted using a dta furnace with the capability of quenching samples during solidification. the melted samples were cooled at 0.008 and 0.083 k/s and subsequently quenched from predetermined tempera...

This article investigates how the growth in income inequality from 1970 to 2000 affected patterns of income segregation along three dimensions: the spatial segregation of poverty and affluence, race-specific patterns of income segregation, and the geographic scale of income segregation. The evidence reveals a robust relationship between income inequality and income segregation, an effect that i...

In many sexually dimorphic mammals, adults tend to form single-sex groups ('social segregation'). It has been assumed that social segregation is simply a by-product of sex differences in habitat use ('habitat segregation'). I tested this assumption on red deer, Cervus elaphus, and feral soay sheep, Ovis aries, using data on group composition, habitat use and space use collected on the Scottish ...

We study workplace segregation in the United States using a unique matched employeremployee data set that we have created. We present measures of workplace segregation by education and language, and by race and ethnicity, and – since skill is often correlated with race and ethnicity – we assess the role of educationand language-related skill differentials in generating workplace segregation by ...

Meiotic cells tightly regulate the number and distribution of crossovers to promote accurate chromosome segregation. Yokoo and colleagues uncover a metazoan-specific, cyclin-like protein that is crucial for crossover formation. They utilize this protein's unique properties to explore a remarkable example of biological numerology, whereby nearly every meiotic cell in C. elegans makes precisely s...

Sexual segregation, or the differential use of space by males and females, is hypothesized to be a function of body size dimorphism. Sexual segregation can also manifest at small (social segregation) and large (habitat segregation) spatial scales for a variety of reasons. Furthermore, the connection between small- and large-scale sexual segregation has rarely been addressed. We studied a popula...
