Family conflict and intragroup marginalization as predictors of acculturative stress in Latino college students.

This study examined the impact of family conflict and intragroup marginalization on acculturative stress in 188 bicultural Latino college students. Results showed that low parental income, low acculturation, perceived family conflict, and perceived intragroup marginalization were related to higher acculturative stress for participants. Intragroup marginalization accounted for a statistically significant proportion of the variance in acculturative stress after all variables were controlled. The findings emphasize the need to recognize culture-specific stressors of college students. Implications for mental health providers are discussed.

Us without them: Evidence for an intragroup origin of positive in-group regard.

Four experiments examined whether group formation and positive in-group regard require interaggregate comparison as the in-group-requires-an-out-group assumption of the metacontrast principle implies. The authors fostered novel social aggregates with or without a contrasting aggregate with which members could compare and varied intra-aggregate factors (interaction or interdependence). Regardless of whether interaggregate comparison was feasible, the intra-aggregate factors increased the perceived entitativity of the aggregate and positive regard toward the aggregate (i.e., social attraction and cooperation among members). Mediation analyses were consistent with the possibility that the intra-aggregate factors promoted entitativity, which in turn promoted in-group regard. These data suggest that group formation and in-group regard have intragroup origins and do not require comparison with a contrasting social aggregate.

陕南农村的信息化差距与信息贫困

改革开放以来,中国追赶全球信息化浪潮的步伐不断加速,取得了令人瞩目的成就。但在中国的信息化进程中,东、西部地区差距正日益扩大。由于大众传播技术和手段的落后,陕南农民在信息革命和网络革命中被逐渐边缘化,形成21世纪新的信息贫困和知识贫困人口,造成经济贫困状态的长期持续。在西部反贫困战略中,大众传媒应有积极作为。

比较文学的基因焦虑感——从ICLA会议主题看比较文学学科的变化

从比较文学的基因焦虑感出发，结合ICLA会议主题，探讨了比较文学的基因焦虑感，提出比较文学的基因缺陷、基因扩增等新见解；结合当前在比较文学界出现的“文化热”以及比较文学中的文学研究被日益边缘化的残酷现实，提出比较文学研究可分为微观研究和宏观研究两大部类的新观点，以缓解比较文学的基因焦虑感，从而促进比较文学学科的发展。     

"Critical history of the acculturation psychology of assimilation, separation, integration, and marginalization": Correction to Rudmin (2003).

Reports an error in the original article by F. W. Rudmin (Review of General Psychology, 2003[Mar], Vol 7[1], pp. 3-37). Six errors in this article are described. Readers of the critical history are also directeced to the work of J. Berry (2003) in acculturation psychology. (The following abstract of this article originally appeared in record 2003-01663-002.) The psychology of intercultural adaptation was first discussed by Plato. Many modern enculturation theories claim that ethnic minorities (including aboriginal natives, immigrants, refugees, and sojourners) can favor either the dominant culture, or their own minority culture, or both, or neither. Between 1918 and 1984, 68 such theories showed varied and inconsistent terminology, poor citation of earlier research, conflicting and poorly tested predictions of acculturative stress, and lack of logic, for example, 2 cultures in contact logically allow 16 types of acculturation, not just 4. Logic explains why assimilation = negative chauvinism = marginality, why measures of incompatible acculturative attitudes can be positively correlated, and why bicultural integration and marginalisation are confounded constructs. There is no robust evidence that biculturalism is most adaptive. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Influence of long-term racial environmental composition on subjective well-being in African Americans.

Two studies (N=126, N=114) of African Americans supported a model predicting that more racially segregated life contexts are associated with feelings of acceptance by other in-group members and, to a lesser extent, rejection by outgroup members. In-group acceptance and out-group rejection in turn influenced identification with the in-group, which was a strong predictor of psychological well-being. Alternative models were not supported. Results suggest that environments that are segregated offer in-group support and acceptance, thereby protecting self-esteem against possible perils of rejection by a powerful out-group. Findings suggest that the improvement of intergroup relations should not be at the expense of intragroup relations. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

三级逆向供应链优化与协调研究

考虑由回收商、再制造商和零售商组成的三级逆向供应链系统。其中再制造商雇用回收商通过向消费者手中买回方式回收废旧产品,并将再制造产品通过零售商再次销售。研究了纯分散式决策模型、再制造商和零售商联盟决策模型、回收商和再制造商联盟决策模型、集中式决策模型4种结构下的逆向供应链优化问题,分别求得不同结构下的回收和销售价格以及回收数量和市场需求。主要的研究结果包括:三级逆向供应链中的双边效应体现为回收价格的降低、销售价格的提高,且此效应随供应链分散决策程度的增加而加剧。最后,设计了合同机制协调此三级供应链系统。     

The loyal member effect: On the preference for ingroup members who engage in exclusive relations with the ingroup.

The goal of this article was to investigate an indirect form of intergroup differentiation in children in the context of racial attitudes: the preference for ingroup members who interact positively with other ingroup members rather than with outgroup members. Study 1 confirmed this general hypothesis with preschool and 1st-grade children, demonstrating that respondents preferred the ingroup member who played only with other ingroup members, evaluated this child more positively, and felt more similar to him or her. Studies 2 and 3 tested the boundary conditions of the phenomenon. Study 4 analyzed developmental changes demonstrating that the effect is no longer observed among 9- to 11-year-old children. Overall, these studies suggest that engaging in positive interactions with the outgroup might have its costs in terms of a relative devaluation and rejection by one's peers. Results are discussed by stressing the importance of intragroup processes for the regulation of intergroup relations among very young children.
