We estimate the size of the African American population in five-year age groups at census dates from 1930 to 1990 using a three-part strategy. For cohorts born after 1935, we follow the U.S. Census Bureau in using classical demographic analysis. To estimate the size of cohorts born before 1895, we use extinct-generation estimates. For remaining cohorts, we implement an age/period/cohort model of census counts. All approaches are applied to a data set in which the age distribution of deaths has been corrected for age misreporting. Results provide strong confirmation of the basic validity of Census Bureau estimates of census undercounts for African Americans while extending estimates to new cohorts and periods. Our estimates are less consistent with an historical series prepared by Coale and Rives (1973). 相似文献

We investigate the extent and implications of cohabitation and marriage among U.S. welfare recipients. An analysis of four data sets (the Current Population Survey, the National Survey of Families and Households, the Panel Study of Income Dynamics, and the National Longitudinal Survey of Youth) shows significant numbers of cohabitors among recipients of AFDC. An even more surprising finding is the large number of married women on welfare. We also report the results of a telephone survey of state AFDC agencies conducted to determine state rules governing cohabitation and marriage. The survey results indicate that, in a number of respects, AFDC rules encourage cohabitation. Finally, we conduct an analysis of the impact of AFDC rules on cohabitation, marriage, and single motherhood and find weak evidence in support of incentives to cohabit. 相似文献

In this article, I call for a phenomenological turn in educating white, pre-service teachers. As opposed to dominant pedagogical models which focus on changing one’s beliefs about race, phenomenology points toward the importance of pre-conceptual, pre-critical forms of racial embodiment. Here I draw upon recent work on the different between body image (beliefs about the body) and body schema (what the body can do). The worry is that existing forms of anti-oppressive education miss the centrality of the schema, and thus do not go far enough in uncovering the embodied, perceptual roots of racism. 相似文献

Research has established that being undocumented is a risk factor for mental and physical health conditions. Much of this work emphasizes undocumented immigrants’ chronic stress, yet key questions about pathways to health remain. The mere state of being undocumented is viewed as a general stressor, without considering actual levels of stress or identifying dimensions of documentation status that contribute to overall stress levels. Drawing on surveys and interviews with undocumented students at the University of California, we uncover the everyday manifestations of four dimensions of immigrant “illegality”: academic concerns, future concerns, financial concerns, and deportation concerns, and their association with reported stress levels and self-rated health. Survey data establish undocumented students’ high levels of stress and poorer health, in comparison to previous research on other national samples. In a structural equation model, we found academic and future concerns to be significantly associated with higher stress, which was in turn, associated with poorer self-rated health. Financial concerns were not associated with higher perceived stress but were directly associated with poorer self-rated health. Notably, deportation concerns did not have any significant independent associations with stress or health. We use our qualitative data to identify specific stressors embedded within these four dimensions. Our findings inform understandings of the health risks arising from documentation status. 相似文献

This article examines the tendencies of LGBT intergenerational theater projects. By engaging with ideas of queer time, temporal drag, and the pervasive heteronormative imagery of heritability and inheritance, this article explores the possibility that LGBT intergenerational projects may generate some of the problems they aim to challenge. Through the lens of queer time, the article describes the normativity generated in LGBT intergenerational theater projects as a form of restrictive interpellation. The article explores the temporal complexities at play in such theater productions as The Front Room, a specific LGBT intergenerational theater project performed in the United Kingdom in 2011. The article concludes by noting some ways in which intergenerational theater projects might seek to work through the embodiment of the historical quotidian as a mode of resistance to normativity’s recirculation. 相似文献

The measurement invariance of the Modern Homonegativity Scale (MHS) was examined among heterosexual female (n = 449) and male (n = 329) university students who were predominantly Mexican American. The MHS demonstrated full invariance of factor loadings and partial invariance of latent intercepts. At the latent mean level, heterosexual men compared to heterosexual women held more negative attitudes toward both gay men and lesbian women. There were no latent mean differences in attitudes toward gay men and lesbian women when rated by either heterosexual men or heterosexual women. The MHS can be used by heterosexual men and heterosexual women to assess their homonegativity. 相似文献

This study revisited the old research question of whether or not maternal employment would adversely affect children's development. We reframed the question by asking how a mother's temporal employment demands might be linked to child development. We used longitudinal data from a sample of 340 white, lower- to middle-class, dual-earner families living in the rural Midwest of the United States. The data were obtained from questionnaires and videotaped observations, and were informed by the mother, the father, the adolescent child, and a trained observer. As predicted, we found a strong relationship between a mother's temporal employment demands and work-family conflict, which was significantly associated with her emotional distress. A husband's egalitarian gender ideology was found to reduce the mother's emotional distress. Maternal distress was then negatively associated with nurturant and involved parenting, which in turn predicted a reduction in the adolescent child's emotional and behavioral problems over time. 相似文献
