Objectives. The purpose of this study was to explore generational differences in math/science enrollment and achievement among Mexican‐American students and the role of family and school contexts in these differences. Methods. We applied survey regression techniques to data from 12,020 adolescents in the National Longitudinal Study of Adolescent Health. Results. Native‐born Mexican‐American students had lower math/science enrollment than their peers, especially after differences in family and school contexts were taken into account. Mexican‐American immigrants had lower achievement when enrolled in such classes, but this was explained by their greater level of family and school disadvantages. Conclusions. Persistence and success in the math/science pipeline, a mechanism of social mobility in the modern economy, would likely be enhanced in the fast‐growing population of Mexican‐American students by improvements in family resources and school organization. 相似文献

Limited research exists about Spanish-speaking social workers that provide bilingual social work services. To date, studies have not exclusively focused on actual language competence of bilingual social workers or even their self-perceived language beliefs. This study reviews the results of a cross-sectional Internet-based survey exploring self-perceived Spanish language skills of bilingual social workers. The nationwide sample consisted of 321 participants who self-rated their self-efficacy Spanish language skills in relation to 5 social work competency categories. Results indicate that the language that participants reported speaking at home versus at work was significantly associated with the self-efficacy ratings. These associations along with implications for social work education are discussed. 相似文献

This qualitative study examines how Mexican American girls define and respond to partner infidelity. In-depth interviews with 24 Mexican American girls, ages 14–18, formed the basis of this study. Although girls variously defined cheating, the majority believed that girls should break up with boyfriends who are physically intimate with an outside partner. Yet, the girls’ real world experiences revealed a more nuanced understanding of how girls actually respond to partner infidelity. While most girls who had been cheated on immediately broke up with their partners, they were also quite likely to reconcile with them for a variety of reasons. Emotional and sexual health implications for relationship cycling---defined as breaking up, getting back together, and breaking up again---are discussed. 相似文献

The purpose of this qualitative study was to explore the role that friendship, trust, and love played in the courtship and marriages of eleven German heterosexual couples (twenty-two individuals, including three couples of mixed national heritage) who reported their marriages to be happy. A conceptual model is proposed of how the components of friendship, trust, and love (i.e., love experienced as emotion, behavior, and commitment) may form a foundation for happy German marriages. Identified themes inform suggestions for how these findings can be used by educators, practitioners, and clergy to support and strengthen German marriages. 相似文献

Over the last two decades, academic debates around neoliberalism in Latin America have shifted from evaluations of the drawbacks and virtues of the application of neoliberal policies for achieving socioeconomic development, towards discussions imagining and implementing alternatives. After thirty years of neoliberal reform, even neoliberal advocates have increasingly recognised the pernicious effects that the process of neoliberalization have had on people's lives. The fleeting left and centre-left moment brought renewed hopes and expectations of a post-neoliberal future. However, post-neoliberal states could not solve the contradictions of neoliberalism and told us much about its resilience and adaptability. This article offers an overview of the dynamics of neoliberalism's resilience and contestation in Latin America as treated by extant literature as a way to account for the politics of neoliberalism in the region, its rise and its current status. 相似文献

We consider the problem of allocating m commodities among n agents with single-peaked preferences. When m≥2 and n=2 any strategy-proof and efficient solution is dictatorial. We propose an extension of the Uniform Rule that (in the two-agents
case) is the only one that satisfies strategy-proofness, envy-freeness, and a weak requirement related to efficiency. Alternatively,
the envy-freeness property may be replaced by weak-anonymity.

Modern technologies are frequently used in order to deal with new genomic problems. For instance, the STRUCTURE software is usually employed for breed assignment based on genetic information. However, standard statistical techniques offer a number of valuable tools which can be successfully used for dealing with most problems. In this paper, we investigated the capability of microsatellite markers for individual identification and their potential use for breed assignment of individuals in seventy Lidia breed lines and breeders. Traditional binomial logistic regression is applied to each line and used to assign one individual to a particular line. In addition, the area under receiver operating curve (AUC) criterion is used to measure the capability of the microsatellite-based models to separate the groups. This method allows us to identify which microsatellite loci are related to each line. Overall, only one subject was misclassified or a 99.94% correct allocation. The minimum observed AUC was 0.986 with an average of 0.997. These results suggest that our method is competitive for animal allocation and has some interpretative advantages and a strong relationship with methods based on SNPs and related techniques. 相似文献

In response to the global financial crisis that started in August 2007, central banks provided extraordinary amounts of liquidity to the financial system. To investigate the effect of central bank liquidity facilities on term interbank lending rates near the start of the crisis, we estimate a six-factor arbitrage-free model of U.S. Treasury yields, financial corporate bond yields, and term interbank rates. This model can account for fluctuations in the term structure of credit and liquidity spreads observed in the data. A significant shift in model estimates after the announcement of the liquidity facilities suggests that these central bank actions did help lower the liquidity premium in term interbank rates. 相似文献

We compared the robustness of univariate and multivariate statistical procedures to control Type I error rates when the normality and homocedasticity assumptions were not fulfilled. The procedures we evaluated are the mixed model adjusted by means of the SAS Proc Mixed module, and Bootstrap-F approach, Brown–Forsythe multivariate approach, Welch–James multivariate approach, and Welch–James multivariate approach with robust estimators. The results suggest that the Kenward Roger, Brown–Forsythe, Welch–James, and Improved Generalized Aprroximate procedures satisfactorily kept Type I error rates within the nominal levels for both the main and interaction effects under most of the conditions assessed. 相似文献
