Prior to World War II, the median age at marriage for white men was later than that for African American men. Since World War II, African American men have, on average, married later than white men. A discrete-time hazard model using data from the National Survey of Families and Households was analyzed to explain this racial cross-over in men’s timing of marriage. Dramatic increases in the educational attainment of African American parents and the large movement of African Americans out of the South brought about the racial cross-over in the timing of marriage. Increased enrollment in higher education among African American men also contributed to the racial cross-over in the timing of marriage. Although lack of full-time employment and military service delayed marriage, these factors did not contribute to the racial cross-over. 相似文献

The ‘child’ in child welfare/protection is seen as a dependent waif and an object of interest, on whose behalf adults speak and act. An alternative perspective has argued for child‐centredness, and includes concepts of child liberation, rights and citizenship. Policymakers and practitioners who may accept the underlying principles may be concerned about the appropriateness and applicability of such principles in relation to practice with children and their parents in child welfare/protection cases. This paper discusses a conceptual framework for research that aims to explore participatory and child‐centred professional practice by critically evaluating and developing, for professional practice, the practical meanings of ‘participatory’ and ‘children as citizens’. We do not present research outcomes based on empirical data; instead, we present our conceptual framework as the first stage of research in progress into participatory and child‐centred professional practice. 相似文献

This article deals with the effects of globalization on individual life courses and employment careers and the resulting changes in patterns of social inequality in modern societies. Empirically, we draw back to results from the international research project GLOBALIFE which studied the effects of globalization on modern life courses for the first time. The results show that the effects of globalization on individual life courses show marked differentiation with regards to specific life course phases: while especially the employment of mid-career men remained considerably stable under globalization, the careers of young adults, mid-career women as well as late-career workers underwent significant alterations. At the same time, results from the GLOABLIFE study indicate that the changes induced by globalization have not yet led to identical results at the national level. Globalization appears to be differentially filtered by deeply embedded and path-dependent national institutions. These “institutional packages” entail variable forms of labour market “flexibilisation” which themselves differentially shape patterns of social inequality in modern societies: While Scandinavian countries have largely succeeded in limiting an increase in social inequality under globalization through active public welfare engagement, globalization has led to a significant amplification of social inequalities in other regime types, either between labour market insiders and outsiders (in conservative and Southern European countries) or between individuals with different human capital resources (in liberal countries). 相似文献

To develop a quantitative exposure‐response relationship between concentrations and durations of inhaled diesel engine exhaust (DEE) and increases in lung cancer risks, we examined the role of temporal factors in modifying the estimated effects of exposure to DEE on lung cancer mortality and characterized risk by mine type in the Diesel Exhaust in Miners Study (DEMS) cohort, which followed 12,315 workers through December 1997. We analyzed the data using parametric functions based on concepts of multistage carcinogenesis to directly estimate the hazard functions associated with estimated exposure to a surrogate marker of DEE, respirable elemental carbon (REC). The REC‐associated risk of lung cancer mortality in DEMS is driven by increased risk in only one of four mine types (limestone), with statistically significant heterogeneity by mine type and no significant exposure‐response relationship after removal of the limestone mine workers. Temporal factors, such as duration of exposure, play an important role in determining the risk of lung cancer mortality following exposure to REC, and the relative risk declines after exposure to REC stops. There is evidence of effect modification of risk by attained age. The modifying impact of temporal factors and effect modification by age should be addressed in any quantitative risk assessment (QRA) of DEE. Until there is a better understanding of why the risk appears to be confined to a single mine type, data from DEMS cannot reliably be used for QRA. 相似文献

Under what conditions do sexual pleasure and desire get addressed in news coverage of sexual health issues like female genital cutting (FGC) and male circumcision (MC)? In this study we employed an embodied ethnosexuality approach to analyze sexual themes in 1,902 items published from 1985 to 2009 in 13 U.S. and 8 English newspapers and news magazines. Journalists' discussions of sexual pleasure, desire, control, problems, and practices differed in quantity and quality depending on the practice and nation to which they pertained. News coverage in both nations presented FGC as impeding female sexual pleasure, desire, and activity in ways that reinforce (hetero)sexist understandings of sexuality. The English press depicted MC as diminishing male sexuality, whereas U.S. papers showed it as enhancing male sexuality. These patterns are influenced by, and serve to reinforce, cultural norms of embodiment and ethnosexual boundaries based on gender, race, and nationality. They may, in turn, shape public understandings of FGC and MC as social problems. 相似文献

Urban plant biodiversity is influenced by both the physical environment and attitudes and preferences of urban residents for specific plant types. Urban residents are assumed to be disconnected from their immediate environment, and cultural and societal factors have been emphasized over environmental factors in studies of landscaping choices. However, we postulate that local climatic and environmental factors can also affect preferences for plant attributes. Therefore, spatial and temporal patterns in urban tree biodiversity may be driven not only by the direct effect of environmental variables on plant function, but also by the effect of environmental variables on attitudes toward trees and associated choices about which types of trees to plant. Here, we tested the relative effects of socio-economic and local environmental factors on preferences toward tree attributes in five counties in southern California in and surrounding Los Angeles, based on 1,029 household surveys. We found that local environmental factors have as strong an effect on preferences for tree attributes as socio-economic factors. Specifically, people located in hotter climates (average maximum temperature 25.1 °C) were more likely to value shade trees than those located in cooler regions (23.1 °C). Additionally, people located in desert areas were less likely to consider trees to be important in their city compared with people located in naturally forested areas. Overall, our research demonstrates the inherent connections between local environmental factors and perceptions of nature, even in large modern cities. Accounting for these factors can contribute to the growing interest in understanding patterns of urban biodiversity. 相似文献

The Protestant work ethic (PWE), the belief that hard work leads to success, is a quintessentially American belief. The present research addresses a critical gap in psychological research on PWE: can a single, large-scale sociopolitical event (government's response to Hurricane Katrina) produce changes in PWE? We review evidence showing that the salience of Katrina led to a reduction in African Americans' (not European Americans') endorsement of PWE and that this result appears explained by African Americans' greater belief in the government's inadequate response to Katrina victims, who were predominately African American. The implications of differential endorsement of PWE for future expectations of societal treatment, motivation to pursue important goals, and willingness to endorse structural corrections of inequality are discussed. 相似文献

This study examines the association between work-related insecurity and health, with a focus on how this relationship is moderated by social location (gender, age and race). Drawing on longitudinal data from a Canadian labour market survey (1999–2004) the findings show that certain groups have a higher prevalence of exposure to certain types of work-related insecurity including (among others) low earnings, poor job mobility and the absence of union protection. Results from regression analyses indicate that the negative health impact of work-related insecurity is also unevenly distributed across different social locations. In some cases, older age and visible minority status significantly elevated the health risk posed by work-related insecurity. The implications of these findings are discussed in terms of major shifts in the demographic composition of the labour market due to workforce ageing and the increased participation of women and visible minorities. 相似文献
