Over the last 20 years, policymaking related to immigrant populations has increasingly been conducted at the state-level. State immigrant polices may influence immigrant poverty by determining immigrants’ level of access to social, economic, political, and health resources and by shaping the social environment. Further, these immigrant policies may shape the stratification between citizens and noncitizens, potentially contributing to distinct patterns of disparities in poverty by both citizenship and race/ethnicity. To assess the relationship between immigrant policy and socioeconomic stratification of immigrants across citizenship status and race/ethnicity in the U.S., we combined data from the 2014 American Community Survey and a measure of level of inclusion of state immigrant policies. We estimated fixed-effects logistic regressions to test the associations between poverty and the interaction of level of inclusiveness, citizenship, and race/ethnicity, controlling for state- and individual-level characteristics. Results showed that there are significant disparities in poverty by citizenship status and race/ethnicity. Asian/Pacific Islander (API) noncitizens experienced lower levels of poverty in states with higher levels of inclusion. Both Latino and API citizens experienced lower levels of poverty in states with higher versus lower levels of inclusion. Among Latinos, the gap in poverty rates between noncitizens and citizens is larger in more inclusive than less inclusive ones, suggesting that the potential positive impact of more inclusive environments does not necessarily translate to the most vulnerable Latino group. The level of inclusion was not associated with differences among Whites and Blacks. Findings suggest that states with more inclusive immigrant policies may foster environments that advance the economic well-being of API noncitizens, as well as API and Latino citizens.  相似文献

Eating pathology is generally considered to affect females during adolescence and early adulthood. However, in recent years, there has been an increased recognition that disordered eating occurs in middle-aged and elderly women and that the presentation is similar to that of eating disorders in younger women. In the research presented here, results of an Internet survey of older adult women (N = 245; aged 60–90 years) indicate that the factors significantly associated with eating pathology—perfectionism, depression, and sociocultural pressures to be thin—closely parallel those reported for both younger and middle-aged women.  相似文献

How did Rational Choice Theory (RCT), traditionally rejected by sociologists for its economic individualism, rise rapidly in the 1980s and the 1990s to theoretical and institutional prominence within sociology? Drawing on Frickel and Gross’ (American Sociological Association, 70(2):204–232 2005) framework for the emergence of scientific/intellectual movements (SIMs), we argue that RCT rose to prominence in sociology in conjunction with: 1) high status actors’ criticism of the previously dominant paradigm, structural functionalism; 2) favorable structural conditions that provided entrepreneurial access to key resources; 3) proliferation through micromobilization contexts; and 4) the ability of those espousing RCT for sociology to draw on dominant cultural motifs outside of academia. The rise of RCT in American sociology provides a case study for how scientific/intellectual movements can find an audience in academic contexts that are predisposed to oppose them.  相似文献

In reviewing peer-leader feedback within Multi-Source Feedback programs, the group aggregate agreement (GAA) method is contrasted with self-other agreement (SOA). Past research (Markham, Smith, et al., 2014) has demonstrated convergence problems with GAA for groups of peer raters. To evaluate dyadic convergence, we used the Benchmarks data to investigate two derailment factors (Building & Mending Relationships and Interpersonal Problems) for 4607 peers describing 1505 focal respondents. For high-agreement dyads, the rtotal = ? 0.66** with 88% of the combined variance and covariance based on dyadic averages converging as whole units. Only 50% of all dyads demonstrated this type of high convergence. For low agreement dyads, the matching correlation (rtotal = ? 0.56**) was almost exclusively a function of within-dyad divergence with only 4% stemming from between-dyad sources. Research implications for evaluating SOA under these agreement conditions are highlighted. Practitioner applications for using an entity-based visualization of dyads also are prototyped and discussed.  相似文献

Young, rural Black men are disproportionately affected by sexually transmitted infections (STIs), a consequence, in part, of multiple sexual partnerships. We conducted a prospective study that examined the influence of masculinity ideology on changes in numbers of sexual partners in this population. We focused on a set of high-risk attitudes termed reputational masculinity. Community disadvantage during young adulthood was examined as a risk factor for reputational masculinity ideology, and vocational commitment was examined as a potential protective factor. The sample included 505 African American men ages 19 to 22 from high-poverty rural communities. Men reported their numbers of sexual partners during the past three months, masculinity ideology, community disadvantage, and vocational commitment. Follow-up data were collected 18 months after baseline assessment. Negative binomial modeling was used to test study hypotheses. Results indicated that community disadvantage was associated with increases in reputational masculinity during early adulthood, which in turn were linked to increases in numbers of sexual partners. Vocational commitment interacted with reputational masculinity to forecast numbers of sexual partners, attenuating the influence of reputational masculinity. Reputational masculinity and promotion of engagement with the workplace may be important targets for interventions designed to reduce sexual risk behavior.  相似文献

Conventionally, a ridge parameter is estimated as a function of regression parameters based on ordinary least squares. In this article, we proposed an iterative procedure instead of the one-step or conventional ridge method. Additionally, we construct an indicator that measures the potential degree of improvement in mean squared error when ridge estimates are employed. Simulations show that our methods are appropriate for a wide class of non linear models including generalized linear models and proportional hazards (PHs) regressions. The method is applied to a PH regression with highly collinear covariates in a cancer recurrence study.  相似文献

Many scholars argue that the persistence of son preference in China is driven by greater anticipated old‐age support from sons than from daughters and the absence of formal financial mechanisms for families to save for retirement. The introduction of a voluntary old‐age pension program in rural China in the 1990s presents the opportunity to examine (1) whether parents with sons are less likely to participate in pension plans and (2) whether providing access to pension plans affects parental sex‐selection decisions. Consistent with the first hypothesis, we find that parents with sons are less likely to participate in the pension program and have less financial savings for retirement. Consistent with the second hypothesis, we find that an increase in county‐level pension program availability is associated with a slower increase in the sex ratio at birth.  相似文献
