ABSTRACT

The 2010 Patient Protection and Affordable Care Act (ACA) aimed to increase health insurance access for the over 47 million uninsured people in the U.S.A., among whom ethnoracial minorities had the highest uninsured rates before the ACA. Studies have shown that Latinos have had the greatest improvements in health coverage under the ACA, but many may be at a significant disadvantage, specifically due to their nativity and immigration status, as the ACA explicitly excludes unauthorised immigrants from most of its provisions. Using the 2015 Latino National Health and Immigration Survey, a nationally representative sample of Latinos (n?=?1493), we find that variation in health insurance access among Latinos can be traced to immigration status. This study finds no differences among U.S.-born versus foreign-born Latinos in the likelihood of being uninsured in 2015. However, among foreign-born Latinos, unauthorised immigrants are five times more likely than naturalised citizens to be uninsured and less likely to visit a primary care provider or clinic, even after controlling for other factors including language, income and education.  相似文献

This paper analyses the role of practices and representations of mobility in supporting particular kinds of gender orders. While scholarship has shown the various ways women are materially and symbolically ‘fixed’ in place, less attention has been paid to how discourses and practices of mobility interface with systems of gender differentiation more broadly. This work is based on a robust empirical base of 55 interviews, 90 h of participant observation and an analysis of museum displays in Kalgoorile, Western Australia, an iconic frontier mining town selected for this investigation as a site of strongly bifurcated gender discourses. Analysing our field data through the lens of feminist theory which problematizes gender binaries, we argue that while some narrations of gender mobilities serve to reinforce gender binaries, lived practices of movement can also destabilise (idealised) notions of gendered movement. This paper extends conceptual work by advancing understanding about the role of mobility within systems of gender differentiation, showing how lived practices of mobility are just as likely to challenge idealised patterns of gendered movement as they are to reinforce these patterns.  相似文献

Studying in-group affiliation preferences can be a valuable tool for understanding race relations in the contemporary United States. We draw on theories of social dominance and social identity to analyze racial attitudes, as measured by the Social Distance Scale, for a subset of black and white students at the University of Mississippi. While both black and white students expressed strong in-group preference, this preference was stronger for whites than for blacks, especially for white women presently affiliated or planning to affiliate with campus Greek organizations. Social dominance orientation, a measure describing whether social inequalities are accepted and justified, mediated the greater in-group preference of many whites, especially for intimate or high-power relationships. We discuss possible individual and institutional causes for the differences we observe, and we draw implications for understanding continued self-segregation both on- and off-campus in a society that implicitly, and sometimes explicitly, espouses “color-blind” ideals.  相似文献

We use data from the 2006 American Community Survey to examine race and ethnic differences in the effects of marital status and co-residence of the middle generation on the likelihood of poverty among grandfathers who have primary responsibility for co-resident grandchildren (N = 3,379). Logistic regression results indicate that race/ethnicity and household composition are significant predictors of poverty for grandfather caregivers: non-Hispanic white grandfathers, those who are married, and those with a co-resident middle generation are the least likely to be poor. The effects of race/ethnicity, marital status, and the presence of a middle generation are, however, contingent upon one another. Specifically, the negative effect of being married is lower among grandfathers who are Hispanic, African American, non-Hispanic, and non-Hispanics of other race/ethnic groups compared to whites. In addition, having a middle generation in the home has a larger negative effect on poverty for race/ethnic minority grandfathers than for non-Hispanic whites. Finally, the combined effects of marriage and a middle generation vary across race/ethnic group and are associated with lower chances of poverty among some groups compared with others. We use the theory of cumulative disadvantage to interpret these findings and suggest that race/ethnicity and household composition are synergistically related to economic resources for grandfather caregivers.  相似文献

We address a long hypothesized relationship between the proximity of individuals’ dwelling units and their kinship association. Better understanding this relationship is important because of its implications for contact and association among members of a society. In this paper, we use a unique dataset from Nang Rong, Thailand which contains dwelling unit locations (GPS) and saturated kinship networks of all individuals living in 51 agricultural villages. After presenting arguments for a relationship between individuals’ dwelling unit locations and their kinship relations as well as the particulars of our case study, we introduce the data and describe our analytic approach. We analyze how kinship – considered as both a system linking collections of individuals in an extended kinship network and as dyadic links between pairs of individuals – patterns the proximity of dwelling units in rural villages. The results show that in general, extended kin live closer to one another than do unrelated individuals. Further, the degree of relatedness between kin correlates with the distance between their dwelling units. Close kin are more likely to co-reside, a fact which drives much of the relationship between kinship relatedness and dwelling unit proximity within villages. There is nevertheless suggestive evidence of a relationship between kinship association and dwelling unit proximity among kin who do not live together.  相似文献

Multivariate genetic studies have revealed genetic correlations between antisocial behavior (ASB) and substance use (SU). However, ASB is heterogeneous, and it remains unclear whether all forms are similarly related to SU. The present study examines links between cannabis use, alcohol consumption, and aggressive and delinquent forms of ASB using a behavioral genetic approach. Participants were 1,688 adolescents (482 monozygotic twins, 852 dizygotic twins, and 354 nontwin siblings) aged 15–23 years old (M = 16.91), sampled from the community in the U.K. Multivariate model fitting revealed that the genetic components of alcohol consumption and cannabis use correlated with those of both aggression (.21 and .49, respectively) and delinquency (.35 and .69, respectively). Results suggest that both aggression and delinquency have genetic effects in common with alcohol consumption and cannabis use.  相似文献

The purpose of this study was to identify safe patient handling (SPH) curricular content in accredited occupational therapy and occupational therapy assistant programs in the United States of America. A survey was emailed to 155 accredited occupational therapy and 137 accredited occupational therapy assistant programs. With a 39% response rate, most programs addressed SPH curricula by including lectures and lab-based experiences with gait belts, slide boards, and manual transfers while stressing ‘safe’ body mechanics. There were limited responses regarding curricular-based hands-on experience, evaluation of sit-to-stand lifts, how to safely transfer bariatric persons, and information on “no-lift” policies. While occupational therapists have a central role in teaching SPH to caregivers, it is important to enhance SPH curricula to reduce exposure to musculoskeletal risk, thereby, increasing the health and safety of the occupational therapy workforce as well those whom the profession serves.  相似文献

Tax compliance in a between-subjects experiment was higher when the uncertainty about the occurrence of an audit was not resolved until three weeks after participants had filed their tax returns than in a control treatment with immediate uncertainty resolution. Results have important implications for experimental tax research where providing immediate feedback whether participants are audited is common practice.  相似文献
