RESUMEN

As Western societies become more ethnically and culturally diverse, understanding the acculturation of immigrant youth is essential for fostering social cohesion. How the cultural identity formation of ethnic minority adolescents relates to their academic, social, and psychological adjustment is an important and as yet unresolved research question. This study examined to what extent identifying with the heritage and/or host culture is an individual resource or risk factor for the adjustment of immigrant youth in Germany. A random sample of 15-17-year-olds (N = 1992; Mage_w1 = 15.3 years, SD = 0.64; 44.5% girls; 44.7% students with immigrant background) was assessed twice: at the end of 9th and 10th grade. Academic performance and three dimensions of social/psychological adjustment (school attachment, self-esteem, and life satisfaction) were examined. Results showed that biculturalism was the modal identification pattern. Contrary to expectations, cultural identification did not differ systematically with perceived distance from the majority culture. Multivariate structural equation modeling revealed that both heritage and host identification can be developmental resources, but that their effects are dependent on the dimension of adjustment; biculturalism only proved to be a cumulative resource for school attachment. The domain specificity of the findings challenges the generalization claims of predominant acculturation theories.

RESUMEN

What drives socioeconomic success within a society? This study analyzes how late childhood intelligence, parental socioeconomic background, and gender relate to multiple dimensions of adult socioeconomic success (i.e., education, occupational status, and income). A particular focus is placed on education, which is considered as both an indicator of socioeconomic success and a mediator of the relationships with the other dimensions. Randomly sampled participants (N = 5,292) in a German prospective longitudinal study were assessed for the first time at age 12 years in 1991 and for the last time as adults in 2009-10. Comparison of the effects of childhood intelligence and parental socioeconomic background revealed childhood intelligence to be the more powerful predictor of the 3 dimensions of later adult socioeconomic success. Education was the strongest predictor of both later adult occupational status and later adult income, and mediated most of the effects of childhood intelligence and parental socioeconomic background on later adult occupational status and later adult income. A gender income gap was apparent, with men reporting higher income, even when childhood factors and education were controlled. Education barely mediated any gender differences, but family-related structural factors (i.e., working part time and having children) explained much of the gender gap in income.

RESUMEN

Based on theories of social-cognitive development, the present study investigated the yet unknown social structure that underlies the concept of empathy in adolescence. A total of 3.159 seventh graders (13.67 years, 56% girls) from 166 school classes participated by providing information on empathy, related psychosocial factors, and friendship patterns. Social network analyses were used to measure a comprehensive representation of adolescents' social environment by covering individual, group, class, and school characteristics. Multilevel models revealed that individual characteristics as well as contextual factors predict adolescents' level of empathy. Findings indicate that empathy is mirrored in the social structure of adolescents supporting the hypothesis that social demands, which continuously grow with the amount of embeddedness, shape their social understanding.

RESUMEN

This article examines the development of social and ethnic disparities in academic achievement in elementary schooling. It investigated whether reading and mathematics development in 136 mixed-ability classes shows path-dependent processes of cumulative advantage (Matthew effects) from Grades 4 to 6 (Grade 4 mean age = 10.62, SD = 0.57) resulting in growing inequality. Status-dependent processes of cumulative advantage, their interaction with path-dependent processes, and consequences for the degree of social and ethnic inequality are examined. Two complementary methods for analyzing multilevel data are used: growth curve and quasi-simplex models. No evidence for a Matthew effect was found in either domain. A compensation effect emerged for reading, to the benefit of ethnic minorities. A fan-spread effect was found for mathematics, partly attributable to status-dependent processes of cumulative advantage.

RESUMEN

Chlamydia pneumoniae infection has been associated with chronic obstructive airway disease (COPD), asthma, and atherosclerosis. Inflammation and airway remodeling in asthma and COPD result in subepithelial fibrosis that is characterized by the deposition of interstitial collagens and fibronectin. The progression of atherosclerosis is also accompanied by an increased production of interstitial collagens in the intima. As shown by reverse transcription-PCR and immunoblotting, infection of human fibroblasts and smooth muscle cells by C. pneumoniae TW-183 downregulated the expression of type I and III collagen and fibronectin, whereas the level of type IV collagen remained unchanged. Conditioned medium from infected fibroblasts as well as epithelial WISH cells also reduced the expression of interstitial collagens and fibronectin in uninfected cells. In experiments using blocking antibodies, beta interferon was found to contribute to the inhibitory effects of conditioned medium collected from infected fibroblasts. In contrast, downregulation of matrix protein expression by conditioned medium from epithelial cells was caused by interleukin-1alpha, which was not secreted from fibroblasts following chlamydial infection. C. pneumoniae-mediated inhibition of collagen and fibronectin expression was diminished following transfection of fibroblasts with specific small interfering RNA targeting the transcription factor CCAAT/enhancer-binding protein beta. The downregulation of interstitial collagens and fibronectin by the Chlamydia-induced host cell cytokine response may modulate tissue remodeling processes in airway diseases. In atherosclerosis the inhibition of collagen synthesis by C. pneumoniae infection may promote plaque vulnerability, thereby increasing the risk of plaque rupture.

RESUMEN

The authors examine the directionality of effects between global self-esteem, domain-specific academic self-concepts, and academic achievement. Special emphasis is placed on learning environments as potential moderators of the direction of these effects. According to the meritocracy principle presented here, so-called bottom-up effects (i.e., self-esteem is influenced by academic self-concept) are more pronounced in meritocratic learning environments than in ego-protective learning environments. This hypothesis was examined using a three-wave cross-lagged panel design with a large sample of 7th graders from East and West Germany, a total of 5,648 students who were tested shortly after German reunification. Reciprocal effects were found between self-esteem, academic self-concept, and academic achievement. In conformance with the meritocracy principle, support for bottom-up effects was stronger in the meritocratic learning environment.

RESUMEN

Relations between multiple dimensions of self-concept, personality (Big Five), well-being, and academic outcomes (school grades, test scores, coursework selection) for a large (N=4,475) sample of German adolescents support the construct validity of a well-defined, multidimensional set of self-concept factors in relation to personality factors, and vice versa. Confirmatory factor analysis of a German adaptation of the Self Description Questionnaire III demonstrated 17 a priori, reasonably independent self-concept factors (M correlation=.14; SD=.17) that had a highly differentiated pattern of relations with the personality factors and academic outcomes. Consistent with theory and previous research, math and verbal self-concepts were negatively related to each other, and this extreme domain specificity was reflected in the systematic and substantial relations with academic criteria measures. Self-esteem, Big Five, and well-being factors explained only small amounts of variance in academic outcomes and support for their incremental validity after controlling for specific self-concept factors was weak.

RESUMEN

Reciprocal effects models of longitudinal data show that academic self-concept is both a cause and an effect of achievement. In this study this model was extended to juxtapose self-concept with academic interest. Based on longitudinal data from 2 nationally representative samples of German 7th-grade students (Study 1: N = 5,649, M age = 13.4; Study 2: N = 2,264, M age = 13.7 years), prior self-concept significantly affected subsequent math interest, school grades, and standardized test scores, whereas prior math interest had only a small effect on subsequent math self-concept. Despite stereotypic gender differences in means, linkages relating these constructs were invariant over gender. These results demonstrate the positive effects of academic self-concept on a variety of academic outcomes and integrate self-concept with the developmental motivation literature.

RESUMEN

Chlamydia pneumoniae may modulate the proliferation of smooth muscle cells (SMC) in atherosclerotic plaques. Conditioned medium from C. pneumoniae-infected SMC decreased the proliferation of uninfected SMC. Treatment of infected cells with the cyclooxygenase-2 inhibitor NS-398 [N-[2-(cyclohexyloxy)-4-nitrophenyl]-methanesulfonamide] suppressed the up-regulation of prostaglandin E(2) (PGE(2)) and abolished the antimitogenic effect of conditioned medium, suggesting that C. pneumoniae can decrease SMC proliferation via stimulation of PGE(2) synthesis.
