Using longitudinal data from the Fragile Families and Child Well‐being Study (N = 1,162) and the National Evaluation of Welfare‐to‐Work Strategies (N = 1,308), we estimate associations between material and instrumental support available to low‐income mothers and young children’s socioemotional well‐being. In multivariate OLS models, we find mothers’ available support is negatively associated with children’s behavior problems and positively associated with prosocial behavior in both data sets; associations between available support and children’s internalizing and prosocial behaviors attenuate but remain robust in residualized change models. Overall, results support the hypothesis that the availability of a private safety net is positively associated with children’s socioemotional adjustment. 相似文献

During the twentieth century, trends in childlessness varied strongly across European countries while educational attainment grew continuously across them. Using census and large-scale survey data from 13 European countries, we investigated the relationship between these two factors among women born between 1916 and 1965. Up to the 1940 birth cohort, the share of women childless at age 40+ decreased universally. Afterwards, the trends diverged across countries. The results suggest that the overall trends were related mainly to changing rates of childlessness within educational groups and only marginally to changes in the educational composition of the population. Over time, childlessness levels of the medium-educated and high-educated became closer to those of the low-educated, but the difference in level between the two better educated groups remained stable in Western and Southern Europe and increased slightly in the East. 相似文献

Based on Dutch colonial registers (thombos), this paper reconstructs fertility for two districts in Ceylon, 1756–68. It overcomes challenges in data quality by establishing the outer bounds of plausible estimates in a series of scenarios. Among these, total fertility rates (TFRs) averaged 5.5 in one district, but only 2.7 in the other. These figures exclude the victims of infanticide, a custom noted in European travelogues between about 1660 and 1820. Sex ratios among children differed depending on the number of older siblings, and overall, 27?per cent of girls are missing in one district and 57?per cent in the other. There was little significant variation either in the TFR or the sex ratio by socio-economic status, suggesting that poverty was not a key factor in motivating infanticides. Instead, we argue that at least parts of Ceylon had a forward-looking culture of family planning in the eighteenth century, which was lost in subsequent decades. 相似文献

Research on the social determinants of health in developing countries is increasingly focusing on the importance of gender. Cardiovascular conditions such as hypertension are a growing concern in developing countries, where they are now the leading cause of death. Researchers have documented differences in hypertension between men and women, but the importance of gendered practices in shaping these differences has been left unexamined. Using national data from the India Human Development Survey 2005 (N = 101,593), this study assesses the moderating role of two salient and widespread gendered practices—women’s seclusion and decision-making power—on hypertension disparities between women and men. Both seclusion and low decision-making power are associated with increased odds of hypertension for women, but in the case of seclusion reduced hypertension for men. Results also show the gender gap in hypertension is exacerbated with women’s seclusion and low decision-making power. 相似文献

Using multi-level models, the analysis examines female employment and child stunting across 49 developing countries. At the country level, female labor force participation is not associated with malnutrition after controlling for economic development. At the individual level, a binary measure of employment is not significantly associated with malnutrition. However, a more nuanced measure of seven occupational categories shows that certain types of employment improve malnutrition. Professional, clerical, sales, and domestic jobs are associated with reduced stunting. These effects are only partially mediated by wealth, perhaps suggesting that some jobs may bring benefits to the household beyond the sheer acquisition of tangible resources. Agricultural jobs are associated with increased malnutrition. Manual labor and service work do not have an effect on malnutrition, compared to unemployment. Thus, women's employment is not necessarily a mechanism for empowerment and wellbeing. Not all jobs are created equal, and many of them do not confer the benefits that are typically associated with working outside the home. 相似文献

“Why I Can't Stand Out in Front of My House?”: Street‐Identified Black Youth and Young Adult's Negative Encounters With Police 下载免费PDF全文
This street participatory action research (Street PAR) study organized 15 residents to document street‐identified Black youth and adult's negative experiences with police in Wilmington, Delaware. Data were collected on mostly street‐identified Black men and women aged 18–35 in the forms of (1) 520 surveys, (2) 24 individual interviews, (3) four dual interviews, (4) three group interviews, and (5) extensive field observations. Forty‐two percent of survey participants reported being stopped by police in the last year. However, with the exception of being “stopped,” participants overall reported little negative contact with police at least within the past year. Chi‐square and ANOVA analyses suggest an interactional relationship exists between race, gender, and age on experiences with police. Younger Black men (18–21) were found to have the most negative contact with police. Analysis suggests a smaller, more hardened mostly male variant of the larger street community has had repeated contact with police. Qualitative analysis reveals at least two major themes: (1) disrespect and disdain for residents and (2) low motivation for working with police. Street PAR methodology was also found to be instrumental in working with local residents and the Wilmington Police Department to improve conditions between residents and police. 相似文献

Populism as a concept is elusive and has been connected to very different political movements. Generally, populism’s connotations are rather negative and the term is often used pejoratively in the academic field as well. However, Ernesto Laclau has approached populism by arguing that populist reason is a manifestation of political logic in which group identification – formed through various signifiers such as ‘the people’, which are articulated as part of an ‘equivalence chain’ – eventually establishes political agency as a totality. This paper uses Laclau’s articulation theory to analyse the public construction of contemporary populism in the Nordic countries of Sweden, Finland, Norway and Denmark. The analysis demonstrates that mainstream media frame populism rather negatively, although examples of the term’s positive identification with ‘the people’ are available, especially in the tabloid media. Thus, the positive identification behind the forming of populist movements clashes with the media discourse that prioritizes established journalistic views, practices and sources, making populism a ‘floating signifier’, that is, a concept that has several meanings which are contested in various public discourses. A general pattern in the construction of populism in Northern European multi-party democracies can be discerned, thus identifying the central role of nationalist and nativist identifications in contingent populist articulations. However, the differences between the Nordic countries emphasize a context-driven approach. 相似文献

The relationship between teen childbearing and depression has been extensively studied; however, little is known about how young women's own attitudes toward becoming pregnant shape this association. This study used data from the National Longitudinal Study of Adolescent Health to investigate whether the relationship between teen childbearing and adult depression is moderated by adolescent attitudes toward becoming pregnant. The results showed that although, on average, women who had first births between ages 16 and 19 experienced no more depressive symptoms in adulthood than women who had first births at age 20 or older, the relationship between teen childbearing and adult depression varied significantly based on adolescent pregnancy attitudes. When they had negative adolescent attitudes toward getting pregnant, teen mothers had similar levels of depression as adult mothers, but when they had positive adolescent pregnancy attitudes, teen mothers actually had fewer depressive symptoms than women with adult first births. 相似文献
