Recent conflicting findings raise the issue of whether observed differences in levels of psychological distress of 1st and later borns are a function of their contemporary social situation, or of basic personality defect in 1 or the other group. Hypotheses which might explain conflicting findings are derived from Schachter's work: among Ss exposed to stressors, 1st borns will show more symptoms...

The risks and returns associated with different choices of electricity generation technology cannot properly be considered in isolation. The paper considers their impact on an investing company, using Mean-Variance Portfolio (MVP) theory to identify optimal generation portfolios in liberalised electricity markets characterised by fuel, CO2, and electricity price risk. The paper demonstrates the...

This study analyses the affectivity of social disgust behind oppressive exclusion minorities, such as forced institutionalisation vagrants in modern Korean society. is divided into two forms: ‘infected vagrants’ during Japanese occupation and ‘vagrants themselves’ developmental state. In both cases, visible power apparatus minorities was socially legitimised by effective use politics purificati...

Social isolation is a potent but little understood risk factor for morbidity and mortality, and its negative consequences are most profound among the elderly, the poor, and minorities, some of the fastest growing segments of the U.S. population. A steadily increasing number of people are living alone and are therefore more likely to experience social isolation. We discuss four mechanisms--attra...

SIGNIFICANCE Social and demographic changes have led to an increased prevalence of loneliness and social isolation in modern society. Recent Advances: Population-based studies have demonstrated that both objective social isolation and the perception of social isolation (loneliness) are correlated with a higher risk of mortality and that both are clearly risk factors for cardiovascular disease (...

Stress is a major risk factor in the onset of several neuropsychiatric disorders including anxiety and depression. Although several studies have shown that social isolation stress during postweaning period induces behavioral and brain molecular changes, the effects of social isolation on behavior during adulthood have been less characterized. Aim of this work was to investigate the relationship...

Exposure to stress during puberty can lead to long-term behavioral alterations in adult rodents coincident with sex steroid hormone-dependent brain remodeling and reorganization. Social isolation is a stress for social animals like mice, but little is known about the effects of such stress during adolescence on later reproductive behaviors. The present study examined sexual behavior of ovariect...

New cells are added in the brains of all adult vertebrates, but fishes have some of the greatest potential for neurogenesis and gliogenesis among all taxa, partly due to their indeterminate growth. Little is known, however, about how social interactions influence cell proliferation in the brain of these fishes that comprise the largest group of vertebrates. We used 5-bromo-2'-deoxyuridine (BrdU...
