The general belief that Asian American adolescents are successful has led researchers to ignore variations in Asian adolescents’ academic success. Using samples of Chinese and Filipino adolescents drawn from the National Longitudinal Study of Adolescent Health, this study examined whether differences between these two groups in acculturation, parent–adolescent attachment, and parental school involvement could account for academic achievement differences. Results revealed that Chinese adolescents generally performed better in school than their Filipino counterparts. Factors that predicted academic achievement were ethnicity, acculturation, and parents’ academic involvement. An interaction was found between ethnicity and acculturation, indicating that acculturation is a predictor of academic performance among Filipino youth but not among Chinese youth. Cultural values in parent–adolescent attachment, acculturation, and parents’ school involvement are discussed. 相似文献

The objective of this study was to determine whether children's characteristics and/or institutional characteristics were predictors of severe punishments (including beatings) and/or frequency of punishments that children received from staff in Romanian institutions. The data was hierarchical with institutionalized children (N = 1391) nested within 44 institutions, and the measurement of punishments by the staff and frequency of punishments had a binary distribution. Thus, multilevel logistic regression models were used to examine the effects of individual and institutional level variables on reported punishments and to account for the clustering of the children within institutions. Two general patterns of results emerged. First, regarding individual level variables, it was found that: (1) amount of time spent by children in their current institutions had a significant effect on the probability of being punished by staff and the frequency of this punishment; (2) the probability of being punished was higher for boys than for girls; and (3) having no siblings in the institution increased the odds of being punished several times. Second, regarding institutional level variables: (4) being in placement centers for school-aged children with a traditional type of institutional organization increased the odds of severe punishment compared to a familial/mixed type. The results of the present study highlight the importance of understanding the consequences of institutionalization in a broader way, where children not only experienced early severe psychosocial deprivation as documented in other studies, but also high levels of severe punishments administered by institutional staff. 相似文献

Parental autonomy support has been related to positive adolescent outcomes, however, its relation to outcomes in collectivist cultural groups is unclear. This study examined relations of specific autonomy supportive behaviors and outcomes among 401 adolescents (Mage = 12.87) from the United States (N = 245) and collectivist-oriented Ghana (N = 156). It also examined whether adolescents’ self-construals moderated the relations of specific types of autonomy support with outcomes. Factor analyses indicated two types of autonomy support: perspective taking/open exchange and allowance of decision making/choice. In both countries, perspective taking/open exchange predicted positive outcomes, but decision making/choice only did so in the United States. With regard to moderation, the more independent adolescents’ self-construals, the stronger the relations of decision making/choice to parental controllingness and school engagement. 相似文献

While social difficulties in autism are well-established, questions remain regarding whether these represent challenges in acquiring or performing such skills, reduced social strengths, or a unique distribution across these domains (i.e., social profile). This study empirically derived social profiles of 211 autistic and non-autistic youth (Mage = 13.50; Autistic N = 150; Male N = 151; 85.3% White). Assessments occurred between 2016 and 2020. Results showed that autistic youth exhibit significantly more social acquisition and performance deficits and fewer strengths than nonautistic youth (ds = −.44 to .65). Performance deficits were most—and acquisition deficits least—prominent within autistic profiles, potentially implicating longstanding theoretical models of social difficulties in autism, and supporting new, idiographic approaches for conceptualizing, assessing, and treating social challenges. 相似文献

The blood-brain barrier (BBB) is a critical structure that serves as the gatekeeper between the central nervous system and the rest of the body. It is the responsibility of the BBB to facilitate the entry of required nutrients into the brain and to exclude potentially harmful compounds; however, this complex structure has remained difficult to model faithfully in vitro. Accurate in vitro models are necessary for understanding how the BBB forms and functions, as well as for evaluating drug and toxin penetration across the barrier. Many previous models have failed to support all the cell types involved in the BBB formation and/or lacked the flow-created shear forces needed for mature tight junction formation. To address these issues and to help establish a more faithful in vitro model of the BBB, we have designed and fabricated a microfluidic device that is comprised of both a vascular chamber and a brain chamber separated by a porous membrane. This design allows for cell-to-cell communication between endothelial cells, astrocytes, and pericytes and independent perfusion of both compartments separated by the membrane. This NeuroVascular Unit (NVU) represents approximately one-millionth of the human brain, and hence, has sufficient cell mass to support a breadth of analytical measurements. The NVU has been validated with both fluorescein isothiocyanate (FITC)-dextran diffusion and transendothelial electrical resistance. The NVU has enabled in vitro modeling of the BBB using all human cell types and sampling effluent from both sides of the barrier. 相似文献

In drawing from social role theory and the match-up hypothesis, the purpose of this study was to determine influential variables regarding the effectiveness of female athlete endorsers. A 2 (gender appropriate/gender inappropriate) × 2 (sport related product/non-sport related product) experiment was conducted with 296 participants from four different universities throughout the United States. Results indicated that type of sport had little effect on credibility measures. Further, the athlete's sport had no effect on athlete-product fit. The most important aspect relative to purchase intentions was the product being endorsed, not the sport in which the athlete competed. Results are discussed in terms of practical implications and theoretical considerations. 相似文献

Chinese leaders have attempted to alleviate international anxiety about its rise to global prominence describing its development as a ‘peaceful rise’ or ‘peaceful development’. Most recently, Chinese leaders have begun deploying a new term, the ‘New Style of Great Power Relations’ (新型大国关系). The purpose of this study is to examine the treatment of the ‘New Style of Great Power Relations’ as a political slogan within the Chinese media as a means to shape a geopolitical worldview among Chinese citizens and international actors. Researchers identified 541 articles from 25 different Chinese media sources selected to represent varying levels of government influence and editorial perspectives. This study found the concept primarily intended to engage the United States by stressing cooperative aspects of U.S.–China relations, but also challenges specific U.S. actions. Those U.S. policies challenged within the Chinese media are portrayed as inconsistent with the ‘new style’ concept’s principles. This forms a ‘rhetorical trap’, as it were for the United States, in that the framing of the discourse implicates U.S. intentions and policies as disingenuous unless the United States changes its policy stances. The essay examines the implications of the discourse for understanding Chinese political communication. 相似文献
