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 ...

the theory of urban ecology is based on explaining urban spatial structure, studying and describing the reciprocal relationship between human societies in the urban areas and the environment, as well as analyzing the circumstances of urban population segregation and production of everyday life spaces. to study and explain urban ecological structure of mashhad, the case study of the article, we ...

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...

It is a matter of debate whether free school choice should lead to higher or lower levels segregation. We investigate how opportunities affect segregation utilizing geocoded Swedish population register data with information on 13 cohorts ninth graders. find that local strongly the sorting students across schools based parents’ country birth and level education. An increase in number leads net s...

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...

Inappropriate handling and disposal practices of healthcare waste (HCW) at healthcare centers are significantly increasing health and environmental hazards. This paper summarizes the existing situation of HCW handling and management practices at healthcare facilities in Kodagu district (India). This study was conducted for a period of six months using well-designed checklists along with field o...

a cytogenetical study on 13 alfalfa (medicago sativa) cultivars available in iranian forest and rangelands genebank was performed in order to obtain basic information on the variability in chiasma frequency/distribution, chromosome association and segregation. such cytogenetic information is useful for planning hybridization programs. cluster analysis of meiotic data and ordination of cultivars...
