We calculated population-level estimates of mortality, functional health, and active life expectancy for black and white adults living in a diverse set of 23 local areas in 1990, and nationwide. At age 16, life expectancy and active life expectancy vary across the local populations by as much as 28 and 25 years respectively. The relationship between population infirmity and longevity also varies. Rural residents outlive urban residents, but their additional years are primarily inactive. Among urban residents, those in more affluent areas outlive those in high-poverty areas. For both whites and blacks, these gains represent increases in active years. For whites alone they also reflect reductions in years spent in poor health. 相似文献

Forty‐nine mother‐infant dyads participated in the study. Mothers were observed during free play with their infants to assess their attention‐directing strategies. Infants were observed during the Bayley to assess their focused attention abilities. Assessments were made when infants were 10 and 18 months. Whereas consistently high levels of maintaining over time were modestly associated with better infant focused attention at 18 months, consistently high levels of redirecting were moderately associated with poorer infant focused attention at 18 months. Additionally, more focused attention was associated with higher Bayley scores at both ages. Although the direction of effects could not be determined, the findings suggest links between maternal attention‐directing strategies (maintaining and redirecting) during play and infant attentional abilities during problem solving. 相似文献

Abstract This research explores violent and property crime rates in nonmetropolitan counties. It is argued that crime rates are lower in these counties because of higher levels of social integration. We test the hypothesis that predictors of crime from social disorganization theory exert different effects on violent and property crimes at different levels of population change in nonmetropolitan counties. We use a spatial lag regression model to predict the 1989–1991 average violent and property crime rates for these counties, taken from the Uniform Crime Reports (UCR). The results show that a factor‐analyzed index of resource disadvantage (poverty rate, income inequality, unemployment, percent female‐headed households) has different effects on both violent and property crime at different levels of population change in nonmetropolitan counties. Contrary to expectations, we find that resource disadvantage exerts a greater positive effect on both violent and property crimes in nonmetropolitan counties that lost population between 1980 and 1990. Implications for theory and research are discussed. 相似文献

Abstract Urban and rural poverty researchers have been paying increased attention to the social context in which the poor are embedded. This paper argues that the scale, familiarity among social actors, and relatively bounded nature of poor rural communities offer unique advantages for understanding why poverty persists across generations in the same places. Rural sociologists can observe the social interaction associated with particular class and race relations, track the evolution of these patterns over time, and uncover the process through which the social class context perpetuates poverty and underdevelopment. Studies of poverty in rural Texas, rural Mississippi, and Appalachia are reviewed to illustrate how political economies that rely on low wages and extreme control over labor generate rigid stratification. This structure of inequality determines social interaction and the allocation of opportunities in rural communities, blocking upward mobility, and undermines investment and trust in social institutions, blocking development. 相似文献
