Using historical census microdata, we present a unique analysis of racial and gender disparities in destination selection and an exploration of hypotheses regarding tied migration in the historical context of the Great Migration. Black migrants were more likely to move to metropolitan areas and central cities throughout the period, while white migrants were more likely to locate in nonmetropolitan and farm destinations. Gender differences were largely dependent on marital status. Consistent with the "tied-migration" thesis, married women had destination outcomes that were similar to those of men, whereas single women had a greater propensity to reside in metropolitan locations where economic opportunities for women were more plentiful.  相似文献

The 1990 Public Use Micro Sample is used to analyze the relationship between immigration and outmigration of the native born in New York City. The study population is limited to native born males who lived in the five boroughs in 1985. The relationship between immigration and the probability of various kinds of moves is assessed using logistic regression. Results suggest that immigration has an insignificant effect on migratory behavior, with the exception of inter-borough migration. Unlike prior work, this study examines a single metro area, and does not limit itself to inter-state migration. These results are consistent with more recent work (Card 2001; Kritz et al. 2001), which has failed to find a positive labor market level effect of immigration on native migratory behavior. The inter-borough finding is consistent with the occurrence of voluntary residential segregation within the city, in which the native born move away from areas of immigrant concentration but do not leave the labor market, yet there is no direct evidence that this process occurred.  相似文献

Evidence of group differences in reproductive control and access to reproductive health care suggests the continued existence of "stratified reproduction" in the United States. Women of color are overrepresented among people with infertility but are underrepresented among those who receive medical services. The authors employ path analysis to uncover mechanisms accounting for these differences among black, Hispanic, Asian, and non-Hispanic white women using a probability-based sample of 2,162 U.S. women. Black and Hispanic women are less likely to receive services than other women. The enabling conditions of income, education, and private insurance partially mediate the relationship between race-ethnicity and receipt of services but do not fully account for the association at all levels of service. For black and Hispanic women, social cues, enabling conditions, and predisposing conditions contribute to disparities in receipt of services. Most of the association between race-ethnicity and service receipt is indirect rather than direct.  相似文献

Patterns and predictors of center-based early care and education (ECE) of children in foster care were examined. Participants included 192 pre-Kindergarten age children in foster care. Foster parents reported demographics, ECE and other service use. Foster care history data was abstracted from case files. High rates of attendance in ECE prior to Kindergarten, including Head Start, other center-based ECE, or both were found. Children who attended Head Start were younger when first placed in foster care. Children who attended other center-based ECE services were more likely to live with kinship foster parents and foster families with higher incomes. Latent class analysis of ECE quantity, quality, type, and duration revealed three patterns: part-time Head Start, part-time other ECE, and full-time mixed ECE. Child and foster family characteristics predicted these patterns, illustrating distinct groups with potential implications for the development of children in foster care.  相似文献

This study examined the relative contributions of the three forms of childhood family violence exposure on physical intimate partner violence (IPV) victimization among recent robbery victims and tested a gender-matching modeling prediction for IPV risk. Data from a sample of 103 male and 93 female victims of a robbery were analyzed to investigate the effects of exposure to childhood physical abuse (CPA), childhood sexual abuse (CSA), and witnessing parental violence on the likelihood of IPV in adulthood. As expected, witnessing parental violence was associated with a 2.4-fold increase in IPV for both men and women. Neither CPA nor CSA was significantly associated with IPV after accounting for the effect of witnessing parental violence. There was support for the gender-matching hypothesis with men more likely to report IPV if they had witnessed mother-to-father violence and women more likely to report IPV if they had witnessed father-to-mother violence. Witnessing parental violence is strongly associated with risk for IPV victimization, particularly when the victim is the same-gender parent. Future directions and clinical implications are discussed.  相似文献

This study examines whether employment status and workplace accommodations are associated with perceived well‐being among workers with disabilities. Data from the 2006 Participation and Activity Limitation Survey conducted by Statistics Canada were used to test the relationship between employment status, receipt of workplace accommodations and well‐being. Findings indicated that fully utilized permanent employees showed greater life satisfaction and less perceived disability‐related discrimination than either temporary workers or permanent workers who were underemployed. These findings support the theory that inadequate employment is associated with deleterious effects on employee well‐being due to inferior need fulfilment and reduced social status. Workplace accommodations were associated with higher levels of well‐being for all workers with disabilities and helped to mitigate the negative effects of temporary status and underemployment. These findings supported the theoretical extension of main effect and buffering models of workplace stress to the prediction of perceived workplace discrimination.  相似文献

Overcoming biases and misconceptions in ecological studies   总被引:2,自引:1,他引:1  
The aggregate data study design provides an alternative group level analysis to ecological studies in the estimation of individual level health risks. An aggregate model is derived by aggregating a plausible individual level relative rate model within groups, such that population-based disease rates are modelled as functions of individual level covariate data. We apply an aggregate data method to a series of fictitious examples from a review paper by Greenland and Robins which illustrated the problems that can arise when using the results of ecological studies to make inference about individual health risks. We use simulated data based on their examples to demonstrate that the aggregate data approach can address many of the sources of bias that are inherent in typical ecological analyses, even though the limited between-region covariate variation in these examples reduces the efficiency of the aggregate study. The aggregate method has the potential to estimate exposure effects of interest in the presence of non-linearity, confounding at individual and group levels, effect modification, classical measurement error in the exposure and non-differential misclassification in the confounder.  相似文献

Research on families in the middle and later years came into its own during the 1990s, documenting the complexity, malleability, and variety of older family connections. We examined 908 articles on family gerontology topics, observing 4 trends: Conceptually, an appreciation for pluralism and resilience as individuals and families age is apparent. Theoretically, life course, feminist, socioemotional selectivity, and family solidarity theories are increasingly applied to intergenerational family relations. Methodologically, new interest in qualitative methods for studying diverse groups has improved the depth with which aging studies can account for variability in old age; new quantitative methodologies have allowed greater sophistication in dealing with longitudinal data. Substantively, there is greater understanding of family caregiving, social support, parent‐child relationships, marital transitions, and grandparenting relationships. The field is poised to take even greater risks in fulfilling the promise of studying linked lives over time.  相似文献
