Why do racial differences in many indicators of mental and emotional well-being show inconsistent patterns? We propose that mental and emotional well-being are influenced by aspects of the social context, including experiences of unfair treatment and the concentration of households with incomes below the poverty level, and that differential exposure to these factors influences racial differences in mental well-being. We analyze the reporting of psychological distress and life satisfaction in a multistage area probability sample of 1,139 African American and white residents of the Detroit metropolitan area aged 18 and older. Both psychological distress and life satisfaction are significantly associated with exposure to unfair treatment and with the proportion of households in the census block group that were below the poverty level. Racial differences in psychological distress and life satisfaction were eliminated or reversed once differentials in the percent of households living below the poverty line and exposure to unfair treatment were accounted for. These findings contribute to a growing body of evidence that "race" effects operate through multiple pathways that include race-based residential segregation and its attendant economic disinvestment at the community level, and interpersonal experiences of unfair treatment.  相似文献

This article describes a framework which attempts to identify R & D new product decision criteria in depth. Recommendations of attributes and measurement yardsticks, and examples of goal values, are difficult to provide since there is little support in this literature. For this reason, the major contribution of the framework is in the treatment of the attributes, yardsticks and goal values as a decision-making system. Attributes, yardsticks and goal values were chosen to complement each other and to describe a content picture.  相似文献

Following initial geological assessments, Poland was identified as having one of the largest reserves of unconventional natural gas in the European Union. The Poles, seeking to diversify their energy sources, met the news with tremendous fanfare. However, shale gas development often requires voluminous speculative activity before the gas can be successfully extracted – an activity which has been rare in Poland, where a lack of critical infrastructure coupled with bureaucratic red tape in the permission process has led to slow growth in exploration activities. This article examines the current situation in Poland's unconventional gas and oil development.  相似文献

This study examines the relationships between and among economic hardship, mothers’ depressive symptoms, nonresident fathers’ parenting, mothers’ parenting and mastery, and their children’s behavioral and cognitive development in poor African American single-mother families. Informed by stress-coping and family process theoretical perspectives, this study estimates the effects of nonresident fathers’ parenting and maternal mastery on child developmental outcomes. Analyses use the first three waves of longitudinal data from a subsample of single, African American and noncohabiting mothers with low income in the Fragile Families and Child Wellbeing Study. Results suggest that nonresident fathers’ parenting is indirectly associated with children’s behavior problems and cognitive development transmitted through mothers’ parenting and mastery. Maternal mastery is also found to be one of the most influential predictors of both developmental outcomes of children. Policy and practice implications of these findings are discussed.  相似文献

Research on gender in psychology has increasingly affirmed diversity in gender, with recognition of binary and nonbinary transgender experiences. However, gender has been presumed to be cisgender (congruent with sex) and binary (either male or female) in classical developmental theories. In response, this review engages in a critical analysis of classical gender development theory informed by findings about gender from research on transgender identities. Under analysis was the concept of gender self-categorization in classical theories of gender development including cognitive developmental theory, developmental gender schema theory, and social cognitive theory. Novel theoretical approaches are then outlined to situate recent advancements alongside classical theory. Conclusions are then drawn with brief recommendations for research methods that aim to include binary and nonbinary transgender participants. Drawing on the findings of this review it has been shown that gender self-categorization is often implicitly presumed to be cisgender identification. To overcome this bias, it is suggested that greater attention to specific gender self-categorization mechanisms are needed to open opportunities to include transgender experiences.  相似文献

Early screening for language problems is a priority given the importance of language for success in school and interpersonal relationships. The paucity of reliable behavioral instruments for this age group prompted the development of a new touchscreen language screener for 2-year-olds that relies on language comprehension. Developmental literature guided selection of age-appropriate markers of language disorder risk that are culturally and dialectally neutral and could be reliably assessed. Items extend beyond products of linguistic knowledge (vocabulary and syntax) and tap the process by which children learn language, also known as fast mapping. After piloting an extensive set of items (139), two phases of testing with over 500 children aged 2; 0–2; 11 were conducted to choose the final 40-item set. Rasch analysis was used to select the best fitting and least redundant items. Norms were created based on 270 children. Sufficient test-retest reliability, Cronbach's alpha, and convergent validity with the MB-CDI and PPVT are reported. This quick behavioral measure of language capabilities could support research studies and facilitate the early detection of language problems.  相似文献
