Mexican American youth are at greater risk of school failure than their peers. To identify factors that may contribute to
academic success in this population, this study examined the prospective relationships from 5th grade to 7th grade of family
(i.e., human capital [a parent with at least a high school education], residential stability, academically and occupationally
positive family role models, and family structure) and individual characteristics (i.e., externalizing symptoms, bilingualism,
gender, and immigrant status) to the academic performance of 749 Mexican American early adolescents (average age = 10.4 years
and 48.7% were girls in 5th grade) from economically and culturally diverse families as these youth made the transition to
junior high school. Results indicated that while controlling for prior academic performance, human capital and positive family
role models assessed when adolescents were in 5th grade positively related to academic performance in 7th grade. Further,
being a girl also was related to greater 7th grade academic success, whereas externalizing symptoms were negatively related
to 7th grade academic performance. No other variables in the model were significantly and prospectively related to 7th grade
academic performance. Implications for future research and interventions are discussed. 相似文献

Experiences with perceived discrimination (e.g., perceptions of being treated unfairly due to race or ethnicity) are expected to impact negatively youths’ prosocial development. However, resilience often occurs in light of such experiences through cultural factors. The current longitudinal study examined the influence of perceived discrimination on the emergence of Mexican American adolescents’ later prosocial tendencies, and examined the mediating role of Mexican American values (e.g., familism, respect, and religiosity). Participants included 749 adolescents (49 % female) interviewed at 5th, 7th, and 10th grade. Results of the current study suggested that, although perceived discrimination was associated negatively with some types of prosocial tendencies (e.g., compliant, emotional, and dire) and related positively to public prosocial helping, the associations were mediated by youths’ Mexican American values. Directions for future research are presented and practical implications for promoting adolescents’ resilience are discussed. 相似文献

The ‘pinkification’ of breast cancer culture in recent years conflates women’s empowerment with the celebration of hyperfemininity. Consistent with this trend, reconstructive surgery post-mastectomy is increasingly normalised: restoring the breasts is to restore ‘lost’ femininity. Contextualised within the pressures of this normalisation, our article explores how women who decide against breast reconstruction negotiate their non-normative ‘flat’ bodies. We examine women’s posts in a breast cancer forum about their refusals of breast reconstruction. Using thematic and feminist post-structuralist analyses, we suggest that although health and body acceptance discourses enable resistance to embodied femininity norms, pressures to conform permeate practices related to appearance. Clothes and prosthetic breasts enabled forum participants to pass as ‘healthy’, ‘whole’, and ‘recovered’. The study’s findings emphasise the limitations to agency and resistance that emanate from the ways constraining gender discourses infiltrate every aspect of a woman’s life. In line with a critical awareness approach to breast cancer education, we discuss the possibilities of resistance afforded by the safe spaces of online communities. 相似文献

Although several literature reviews have been published on public service motivation (PSM), none of them focused solely on Africa. Adopting a systematic review of the literature, we analyse articles on PSM scholarship in Africa published between 2005 and 2017. We found that authors in African PSM is consistently increasing with their research published in highly ranked peer-reviewed journals. The antecedents and consequences of African PSM are similar to those of Western countries. Finally, respondents of African PSM scholarship are skewed towards “managerist” and students’ perspective. We proposed agenda for African PSM research with four key interest areas. 相似文献

Much of the prior work on General Strain Theory (GST) has focused on how strain and negative emotions interrelate to produce
criminal—especially violent—activity. Very little research has extended GST to examine other types of non-criminal, negative
behavior, such as self-harming behaviors associated with disordered eating, a traditionally female-specific self-directed
outcome. Using a sample of 338 young adults (54% female, 95% white), this article applies GST to disordered eating by examining
how strain and negative emotions relate to this particular outcome across gender. Findings indicate that two types of strain
measures predict depressive symptoms among males and females, that inequitable strainful experiences relate to disordered
eating among females but not males, that depressive symptoms but not anger increase disordered eating for both males and females,
and that membership in Greek organizations (sororities or fraternities) is associated with disordered eating but only for
males. Implications for theory and directions for future research are highlighted. 相似文献

This paper examines some of the constitutional aspects of the ‘Future of Europe’ reform process in the light of interactions between German and ‘European’ federalism. Many aspects of the traditions of German federalism and German post-war constitutionalism have been influential, if not to say formative, for the evolution of the EU. These aspects are set out as a frame for the paper, before more detailed analysis of the constitutional process and a particular focus on the division of competences. The constitutional outcome reveals clear German ‘fingerprints’, though that finding needs to be balanced by a recognition of the constitutional debate as multi-perspectival, involving all member states both separately and collectively. 相似文献

The specific historical basis for the development of capitalism in England — and not in France — is traced to the unique structure of English manorial lordship. It is the absence from English lordship of seigneurie banale ‐ the specific political form of parcellised sovereignty that figured centrally in the development of Continental feudalism ‐ that accounts for the peculiarly ‘economic’ turn taken in the development of English class relations of surplus extraction. In France, by contrast, the distinctly ‘political’ tenor of subsequent social development can equally specifically be traced to the central role of seigneurie banale in the fundamental class relations of feudalism. 相似文献
