A regression procedure, using survey data on individual's stated preferences for communities, is used to calculate an index of ‘quality of life’. The survey instrument is extraordinarily simple, asking only for limited information about the subset of communities most well-known to respondents. The index is based upon an assumption about the distribution of the errors individuals make in perceiving the true, underlying index. The index is computed from dummy variables and is shown to have nice properties, including invariance to data ordering and (with full information) constant and equal standard errors associated with relative interplace index values. The index is estimated for a case study of 52 Pennsylvania counties.  相似文献

Two studies are reported that provide additional validity evidence for the Students' Life Satisfaction Scale (SLSS: Huebner, 1991a). In the first study, evidence for the convergent validity of the SLSS is provided by significant negative correlations with measures of depression and loneliness and a significant positive correlation with a measure of self-esteem. Additionally, as evidence of discriminant validity, the SLSS failed to differentiate a normally achieving group of students from a group of at risk students. In the second study, the pattern of correlations between the SLSS, selected demographic variables, IQ scores, and a measure of teacher-reported school behavior problems provided evidence of cross-method convergent and discriminant validity. The SLSS was also able to differentiate a group of emotionally handicapped students from non-emotionally handicapped students. The implications of the findings for further study of the subjective well-being of children are discussed briefly.  相似文献

Human Well-Being in Chinese Cities   总被引:1,自引:0,他引:1  

Does human well-being vary substantially across regions within China and, if so, what forces have contributed to this variation? There are four macro-social change theories that shed light on this question: modernization theory, dependency/world-systems theory, state theory, and human ecology theory. No known study has examined all four theories simultaneously or used recent data. We fill this gap by reporting the results of a study examining the effects of industrialization, foreign penetration, state investment, and population growth (as well as several control variables) on the urban variation of three alternative forms of human well-being in China during the late 1980s. Results provide support for both state theory and human ecology theory, but they provide little or no support for modernization theory and dependency/world systems theory. Implications of the results are discussed.

As fertility differences in the United States diminish, population redistribution trends are increasingly dependent on migration. This research used newly developed county-level age-specific net migration estimates for the 1990s, supplemented with longitudinal age-specific migration data spanning the prior 40 years, to ascertain whether there are clear longitudinal trends in age-specific net migration and to determine if there is spatial clustering in the migration patterns. The analysis confirmed the continuation into the 1990s of distinct net migration "signature patterns" for most types of counties, although there was temporal variation in the overall volume of migration across the five decades. A spatial autocorrelation analysis revealed large, geographically contiguous regions of net in-migration (in particular, Florida and the Southwest) and geographically contiguous regions of net out-migration (the Great Plains, in particular) that persisted over time. Yet the patterns of spatial concentration and fragmentation over time in these migration data demonstrate the relevance of this "neighborhood" approach to understanding spatiotemporal change in migration.  相似文献

This study examines the changing effects of non-family activities on the age of transition to first marriage in four cohorts of individuals across 45 years in the Chitwan Valley, Nepal. The results indicate that school enrolment had a negative effect on both men's and women's marriage rates, while total years of schooling had a positive effect on men's marriage rates. Non-family employment experiences increased marriage rates for men only. Analysing the effects of schooling and employment over time suggests that school enrolment became a growing deterrent to marriage for both sexes, and that non-family employment became an increasingly desirable attribute in men. The results are consistent with changing views about sex roles and schooling over time in the region, as the roles of student and spouse became more distinct. The results also suggest an increasing integration of husbands in the non-family labour market.  相似文献

The 1980s and 1990s have been decades of quitegood economic growth in North America and muchof Western Europe. But how have the fruits ofgrowth been shared? This paper reviews changingincome distributions in the U.S., Germany and theNetherlands. These three countries may be takenas exemplars and leading economic performers in``the three worlds of welfare capitalism''(Esping-Andersen, 1990). The U.S. is a liberalwelfare-capitalist state, Germany a corporatiststate, and the Netherlands (less clearly) asocial democratic welfare-capitalist state. Thepaper focuses particularly on income changes inthe bottom, middle and top quintiles and takesa ten year period into account.Previous analyses have shown that labor andmarket income dispersion are increasing, withincreased returns to human capital. Thepotential impact of government through thetax-transfer system has been largely ignored.All three governments redistribute income fromthe rich to the poor. However, the paper showsthat only the Dutch government hasredistributed sufficiently to ensure that thebottom quintile has gained along with others.In Germany and the U.S. the poorest quintile wasconsiderably worse off in absolute terms at theend of the decade.than the beginning. TheGerman government somewhat counteracted thetrend towards greater income dispersion byredistributing to the poorest quintile, so theloss of market income was partly compensated. In the U.S. the impact of government on thepoorest quintile stayed about the same, so thisgroup ended up with about the same decrease indisposable income as market income.The U.S., Germany and the Netherlands are theonly three countries for which ten or moreconsecutive years of panel data are available.The data come from the PSID-GSOEP EquivalentFile 1980-97 and from a comparable fileconstructed from the Dutch SEP data.

Studies of neighborhoods can benefit from data and theoretical frameworks that allow them to examine the differences between neighborhoods and neighbors. Without this distinction, it is unclear if it is characteristics of the people or the place that are associated with individual outcomes. Using data from the Chitwan Valley Family Study, I explore the differences between neighbors and neighborhoods and their associations with marriage timing. I hypothesize three mechanisms whereby neighbors influence individuals: information sharing, social modeling, and sanctions and rewards among a close primary residential group. I explore three domains in which these mechanisms are likely to operate: education, media consumption, and attitudes. Results indicate that when neighbors have attitudes favoring later marriage and being single, marriage rates decrease, even when controlling for measures that describe the neighborhood’s access to important resources in the form of institutions and services.  相似文献

This paper estimates village-level models of the effects of population variables on the area devoted to upland crop production in Nang Rong district, Thailand. The expansion of upland crops is part of the growth of market agriculture in Nang Rong, and a correlate of deforestation in this setting, The results show that population density (measured as density of village settlement) negatively affects area in upland crops while population growth has a positive effect. Changes in land use associated with population change appear to radiate outward from nuclear village centers. As cash economies are established in rural settings, household formation requires a source of income as well as a subsistence stake. Growth in the population of households is a stronger predictor of the area in upland crops than growth in the number of persons.  相似文献
