Research indicates that closeness of the father‐child bond following parental divorce is associated with better outcomes for children and adolescents. Unlike other investigations, this study takes a long‐term developmental approach to understanding stability and change in postdivorce father‐adolescent relationship closeness. Drawing on Add Health data (n = 483), we examine factors that explain (a) why some high‐quality father‐adolescent relationships remain the same after divorce whereas others decline, and (b) why some low‐quality relationships are stable following divorce whereas others improve. High mother‐offspring relationship quality and offspring feelings of well‐being prevented close father‐offspring relationships from deteriorating. Offspring’s childbearing and cohabitation following parental divorce increase closeness in father‐offspring relationships that were not close prior to divorce. Although a majority of offspring experienced a decline in closeness following divorce, results from this study show that some very close father‐offspring relationships are maintained and some poor relationships become closer. 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

This article shows how time works against parents with learningdifficulties in the child protection system and Children Actproceedings. The prevailing wisdom, embedded in policy and theliterature, is that delay in care cases is bad for the childand may jeopardize his or her future. This paper shows how thepressure to avoid delay might itself be harming some families,especially parents with learning difficulties. Drawing on interviewswith social work practitioners undertaken as part of a largerstudy, the authors describe the various forms of temporal discriminationthat impact on this group of disabled parents. They concludethat procedural time limits make it harder for parents withlearning difficulties to meet the standards and expectationsenforced by Childrens Services and the courts. 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
