The current study examined the unique effects of cumulative sociodemographic risk and immigrant-related stress on mental health symptoms among Mexican-origin immigrant parents and their school-age children. Further, this study tested whether the effects of cumulative sociodemographic risk and immigrant-related stress on child mental health were mediated by parent mental health. Participants included 104 Mexican-origin immigrant families. Families in the study had a child between the ages of 6 and 10 (Mage = 8.39; 61% female). Data were collected across three time points spaced 6 months apart. Immigrant-related stress was found to predict parent mental health, which in turn predicted child mental health. Cumulative sociodemographic risk did not predict parent or child mental health. Mental health symptoms generally decreased over time, but for children, change in mental health symptoms depended on parent mental health symptoms. Given the high levels of mental health symptoms among Mexican-origin parents and children, reducing a context of stress and promoting mental health interventions for Mexican-origin immigrants is critical.  相似文献

Much scholarship on mediated representations of race and gender claims that contemporary texts are examples of post-race and post-feminism, effectively communicating that our society is past the eras of inequality of races and sexes. Yet, many scholars have also argued that such representations are not so straightforward. Extending the work of this latter group of scholars, we call this tension refraction, a term we define as representational practices that draw attention to, or magnify, innate oppositions and inconsistencies in mediated representations surrounding identity markers. Through a case study of the first three seasons of the television series Scandal, we find multiple examples of refraction, as the protagonist Olivia Pope simultaneously embodies and critiques specific race/gender tropes. This ultimately depoliticizes issues of race and gender by simultaneously calling attention to, and drawing attention away from, those issues.  相似文献

A national survey with 876 responses examined whether political consumerism is related to religious factors including beliefs about gay marriage, if the Bible is the literal word of God, religiosity or social capital, altruism or civic engagement, cognitive engagement, and the use of political social and digital media. Results suggest religious factors may be important in political consumption, with political consumers less likely to believe the Bible is the literal word of God, suggesting they perceive self-direction regarding their religious beliefs. Political consumers may exhibit universalism by participating in altruistic activities such as volunteering to help the poor, homeless and elderly. However, given their lack of support for gay marriage, traditional religious teachings may supersede universalism for certain social justice issues.  相似文献

People regularly rely on user-generated contributions to websites to inform their opinions about people, companies, organizations, and products. This study examines how two website affordances uniquely affect the evaluation of user-generated content. Specifically, an experiment was conducted that varied whether a website (a) affords profile owners the ability to delete user-generated contributions or (b) verifies the identity of users who post evaluations of profile owners. The results suggest that although deleting user-generated content is viewed as more problematic, both forms of information control independently affect how viewers evaluate a website and the content it hosts. The findings help establish the conditions under which certain forms of information control differentially produce uncertainty and mistrust and thus have direct implications for warranting theory.  相似文献

Family-friendly benefits are intended to help mothers balance rather than juggle work and family. Prior research assumes that family-friendly benefits have a similar effect on mothers’ persistence in full-time work across parity. However, there is evidence that the transitions to first-time and second-time motherhood are qualitatively, as well as quantitatively, different experiences. Using the National Longitudinal Survey of Youth (NLSY79), we investigate women’s labor force status (full-time, part-time, and not working) after both parity transitions among women who were working in the labor force full-time prior to the birth of their first child. We find that mothers often persist in the same labor force status after the birth of their second child that they held after the birth of their first child, but there is wide variability in labor force and parity pathways. In addition, a wider array of family-friendly benefits is associated with second-time mothers’ full-time work than first-time mothers.  相似文献

There has been an increasing interest in urban forests and the levels of biodiversity they contain. Currently there are no spatially explicit maps of tree species richness in urban areas. This research tests and identifies GIS and remote sensing metrics (climate, area, productivity, three-dimensional structure) hypothesized to be associated with species richness in native forests and identifies methods that can be applied to predict and map tree species richness in cities. We quantified tree species richness, floristic composition, and structure in 28 1-ha plots in the city of Los Angeles. Climate and remote sensing metrics from high-resolution aerial imagery (10 cm), QuickBird (60 cm), Landsat (30 m), MODIS (250 m), and airborne lidar (2 m) were collected for each plot. There were 1208 individual stems and 108 trees identified to species. Species richness ranged from 2 to 31 species per ha and averaged 17 species per ha. Tree canopy cover from QuickBird explained the highest portion of variance (54%) in tree species richness followed by NDVI from Landsat (42%). Tree species richness can be higher in residential urban forests than native forests in the United States. Spatially explicit species richness maps at 1 ha can be created and tested for cities in order to identify both hotspots and coldspots of tree species richness and changes in species richness over time.  相似文献
