We find a strong positive raw correlation between black exposure to whites in their school district and the prevalence of later mixed-race (black-white) births, consistent with the literature on residential segregation and endogamy. However, that relationship is significantly attenuated by the addition of a few control variables, suggesting that individuals with higher propensities to have mixed-race births are more likely to live in desegregated school districts. We exploit quasi-random variation from court-ordered school desegregation to estimate causal effects of school desegregation on mixed-race childbearing, finding small to moderate effects that are largely statistically insignificant. Because the upward trend across cohorts in mixed-race childbearing was substantial, separating the effects of desegregation plans from secular cohort trends is difficult; results are sensitive to how we specify the cohort trends and to the inclusion of Chicago/Cook County in the sample. The fact that the addition of a few control variables substantially weakens the cross-sectional relationship between lower levels of school segregation and higher rates of mixed-race childbearing suggests that a substantial portion of the observed correlation is likely due to who chooses to live in places with desegregated schools. Researchers should be cautious about interpreting raw correlations between segregation—whether residential or school—and other outcomes as causal. Our results also point to the need to carefully explore specification of cohort effects in quasi-experimental designs for treatments where cumulative exposure is important.  相似文献

Abstract

This article investigates how discourses of ageing femininity are constructed and negotiated amongst females in Hip Hop. Through the analysis of narratives and imageries constructed within the music and videos of rap veteran Missy “Misdemeanour” Elliott, press responses to Missy’s work and comparative accounts of other prominent female rappers’ performative strategies, this article explores some of the ways that female artists are responding to socially gendered notions of ageing in Hip Hop. I argue that Hip Hop females are in some cases using Hip Hop as a vehicle for subverting age narratives that are commonly associated with ageing femininity. Murray Forman’s concept of “age-representing” is brought into dialogue with representations of ageing Hip Hop females to support this analysis. The writings of Ros Jennings and Abigail Gardner are also drawn on to form a supportive framework by offering comparative accounts of female ageing in other popular music sub-fields. This article aims to contribute to the growing feminist critique of ageing and popular music culture.  相似文献

Funding decisions to support vulnerable children are tied to child labour statistics, hence the importance of an accurate measurement. The author analyses whether the type of respondent plays an important role in explaining variations in child labour statistics. Using data from two sites in Tanzania, the analysis shows that “whom we ask” matters considerably when estimating the prevalence of child labour. The results suggest that prevalence increases by approximately 35 to 65 per cent when using child self‐reports rather than proxy reports. This bias affects 14 to 31 per cent of the sample, depending on the indicator. Discrepancies decrease as the child ages and increase if proxy attitudes demonstrate opposition to child labour.  相似文献

Limited research on parental well‐being by child age suggests that parents are better off with very young children despite intense time demands of caring for them. This study uses the American Time Use Survey Well‐Being Module (N = 18,124) to assess how parents feel in activities with children of different ages. Results show that parents are worse off with adolescent children relative to young children. Parents report the lowest levels of happiness with adolescents relative to younger children, and mothers report more stress and less meaning with adolescents. Controlling for contextual features of parenting including activity type, solo parenting, and restorative time does not fully account for the adolescent disadvantage in fathers' happiness or mothers' stress. This study highlights adolescence as a particularly difficult stage for parental well‐being and shows that mothers shoulder stress that fathers do not, even after accounting for differences in the context of their parenting activities.  相似文献

The Family Adaptability and Cohesion Scale (FACES) IV does not provide instructions about which family members respondents should think about while answering questions. This study examined which family members respondents thought about while completing the FACES IV, and if this changed measurement invariance and population heterogeneity of the measure. Using a sample of n = 511 individuals, a latent class analysis showed three distinct classes: Nuclear Family, Family of Origin, and All of the Above. The FACES IV demonstrated measurement invariance across classes on the majority of subscales; however, population heterogeneity tests suggested that the means and variances of the subscales varied across classes. The findings suggest further examination of how the measure functions with unique family constellations is warranted.  相似文献

Abstract

This article draws on oral histories from my PhD research to explore how six teenagers, now adults, remember their arrivals in Australia as child refugees from Bosnia. It examines their relationships with other people from Bosnia and the former Yugoslavia, including community groups, and how these relationships have changed over time. In examining these narratives, issues of intergenerational differences are highlighted, with interviewees positioning their experiences in relation to both their parents and their second-generation peers. Finally, it explores how former refugees maintain their relationships with family and friends in Bosnia, suggesting that these transnational connections provide them with as much familiarity and comfort as they do feelings of alienation.  相似文献

La mesure du travail des enfants est une entreprise difficile et incertaine, mais cruciale puisque le ciblage de l'aide en dépend. Dans ce contexte, l'auteure montre à partir de données tanzaniennes, et en utilisant deux définitions du travail des enfants, que le choix du répondant influe considérablement sur les chiffres obtenus, supérieurs de 35 à 65 pour cent quand ce sont les déclarations des enfants qui sont prises en compte plutôt que celles des adultes. Le biais touche 14 à 31 pour cent de l'échantillon. L'écart diminue avec l'âge de l'enfant et se creuse lorsque le répondant adulte est hostile au travail des enfants.  相似文献

In this article, we provide a wide-ranging review of recent research on leader individual differences. The review focuses specifically on the explosion of such research in the last decade. The first purpose of this review is to summarize and integrate various conceptual frameworks describing how leader attributes influence leader emergence and leader effectiveness. The second purpose is to provide a comprehensive review of empirical research on this relationship. Also, most prior reviews primarily examined leader personality traits; this review includes a broader array of leader attributes, including cognitive capacities, personality, motives and values, social skills, and knowledge and expertise. The final broad purpose of this paper is to review and integrate situational and contextual parameters into our conceptual framing of leader individual differences. Few, if any, prior reviews have systematically accounted for the critical role of such parameters in cuing, activating, or delimiting the effects of particular leader attributes. We do so in this article.  相似文献

Family formation changed dramatically over the 20th century in the United States. The impact of these changes on childbearing has primarily been studied in terms of nonmarital fertility. However, changes in family formation behavior also have implications for fertility within marriage. The authors used data from 10 fertility surveys to describe changes in the timing of marital childbearing from the 1940s through the 21st century for non‐Hispanic White and non‐Hispanic Black women. Based on harmonized data from the Integrated Fertility Survey Series, the results suggest increasing divergence in fertility timing for White women. A growing proportion of marriages begin with a premarital conception; at the same time, an increasing proportion of White women are postponing fertility within marriage. For Black women, marital fertility is increasingly postponed beyond the early years of marriage. Evaluating the sequencing of marriage and parenthood over time is critical to understanding the changing meaning of marriage.  相似文献

Studies across diverse national contexts reliably show that married men earn more than unmarried men, but the mechanisms responsible for this are still disputed. This article explores the male marriage wage premium from a new perspective, using longitudinal qualitative data from Russia (N = 94). Qualitative research is particularly suited to identifying underlying processes and, by analyzing men's accounts of the influence of their marital trajectories on their work, the authors were able to reexamine existing hypotheses and develop new ones. They propose 4 mechanisms that they hypothesize can influence men's work motivation and performance: premarital planning, 2 distinct “breadwinner” effects using expectancy and self determination theory, and monitoring by wives. They integrate these mechanisms within gender theory, arguing that the treatment aspect of the male marriage wage premium is an outcome of the “coproduction” of masculinity within marriage. Their recontextualization of existing theory also enables them to reveal weaknesses in the specialization hypothesis.  相似文献
