初中一,二年级学生的亲子冲突

本研究选取北京市两所普通中学１９２名初一和初二学生为被试,通过学生对８个方面亲子冲突的评价,探讨初中生亲子冲突的特点。研究发现,（１）初中生早期的亲子冲突处于较低水平;（２）与母亲的冲突多于与父亲的冲突,女生尤其如此;（３）多数亲子冲突随年级而增加;（４）在多数冲突上,男生与父母的冲突多于女生;（５）亲子冲突最多的三个方面为日常生活安排、学业和家务,而冲突最少的为隐私。     

Bayesian Factor Analysis as a Variable-Selection Problem: Alternative Priors and Consequences

Factor analysis is a popular statistical technique for multivariate data analysis. Developments in the structural equation modeling framework have enabled the use of hybrid confirmatory/exploratory approaches in which factor-loading structures can be explored relatively flexibly within a confirmatory factor analysis (CFA) framework. Recently, Muthén & Asparouhov proposed a Bayesian structural equation modeling (BSEM) approach to explore the presence of cross loadings in CFA models. We show that the issue of determining factor-loading patterns may be formulated as a Bayesian variable selection problem in which Muthén and Asparouhov's approach can be regarded as a BSEM approach with ridge regression prior (BSEM-RP). We propose another Bayesian approach, denoted herein as the Bayesian structural equation modeling with spike-and-slab prior (BSEM-SSP), which serves as a one-stage alternative to the BSEM-RP. We review the theoretical advantages and disadvantages of both approaches and compare their empirical performance relative to two modification indices-based approaches and exploratory factor analysis with target rotation. A teacher stress scale data set is used to demonstrate our approach.     

Acculturation,Economic Stress,Social Relationships and School Satisfaction Among Migrant Children in Urban China

Rural to urban migration has become a prominent phenomenon in China. In linking migration to children’s school trajectories, this mixed-methods study explored a range of cultural and contextual factors that contribute to Chinese children’s school wellbeing in the migratory process. The key variables included acculturative attitudes, economic stress, and relationships with family, teachers and peers. The study drew upon survey data from a sample of 301 Chinese migrant students (4th–9th grade) together with in-depth interviews involving ten selected students focusing on how migrant children’s school happiness and productivity are influenced by acculturation, economic hardship, and social relationships. The quantitative analysis indicated the critical role of integrative states in promoting school satisfaction and achievement. Migrant children with better social relations scored higher levels of hope, which in turn contributed to better school outcomes. Contrary to previous findings, economic stress did not hinder school outcomes for these Chinese migrant children, but appeared to act as a positive motivational factor for pursing academic success. The qualitative analysis echoed the quantitative findings, and provided further explanations for the complexity and particularity of these phenomena.     

Culture and the Structure of Affect: A Bifactor Modeling Approach

This paper tested the impact of culture on the basic structure of affect. It examined positive affect and negative affect at three levels of activation in the U.S. and China. It used a well-suited tool, the bifactor model, to separate the common variance shared by all types of affect from the variance unique to each. The findings indicate that the structure of affect is different cross-culturally. In the U.S., the most fundamental dimension is defined by moderate activation of positive affect and negative affect, which is the largely bipolar dimension of pleasure-displeasure, whereas in China, it is defined by moderate activation of positive affect only, which is pleasure. In both cultures, negative affect across levels of activation forms another important dimension. Beyond these basic dimensions, secondary dimensions are also identified in both cultures: high activation positive affect, low activation positive affect, and low activation negative affect. They form relatively weak unique factors, independent of the two basic dimensions, suggesting that they are largely mixtures of the basic dimensions.     

Work-to-Life Spillover Effect of Leader–Member Exchange in Groups: The Moderating Role of Group Power Distance and Employee Political Skill

While prior studies have focused on the effect of leader–member exchange (LMX), representing a dyadic differentiated exchange relationship between a leader and followers, on employees’ job-related outcomes, how LMX at the group level influences one’s life domain has been ignored. The present study shifted attention to the relationship between LMX mean and employee life satisfaction as well as the boundary conditions. Using a sample of 471 employees from 53 groups and hierarchical linear modeling, we examined the cross-level main effect of LMX mean on life satisfaction and the moderation of group power distance and individual political skill. The results revealed that LMX mean had a work-to-life spillover effect on employee life satisfaction. Employee political skill positively moderated the relationship between LMX mean and life satisfaction, whereas group power distance negatively moderated the relation. Theoretical and practical implications were further discussed.     

Criminal law,multicultural jurisdictions and cultural evidence

This article investigates whether providing minority groups with power over criminal law can create injustices that target lesbians, gays and bisexuals within those groups. In order to carry out the task of evaluating to what extent providing power over criminal law to minority groups can result in negative consequences for lesbian, gay and bisexual individuals, this paper assesses the work of Ayelet Shachar. I contend that her model leaves lesbians, gays and bisexuals within minorities vulnerable because her division of jurisdictions collapses when put into practice; additionally, her principles do not provide normative guidance for avoiding jurisdictions that criminalise homosexuality, and that protect lesbian, gay and bisexual individuals from violence. This rejection of transformative accommodation, however, does not mean that cultural evidence is irrelevant for criminal procedures. Rather, I assert that cultural evidence is relevant for trials and including it does not jeopardise the interests of lesbian, gay and bisexual individuals.     

Differences in the micromechanical properties of dendrites and interdendritic regions in superalloys

Statistical analysis of white-light interferometry (WLI) experiments performed on Ni-based single-crystal superalloys (SX) have revealed a different height distribution between the dendritic cores (DCs) and the interdendritic regions (IRs) of the polished samples. The micromechanical property difference is largely ascribed to the uneven distribution of the alloying elements. In this context, possible reasons for this difference are discussed by comparing with different experiment results obtained by previous researchers, and a proposal forecasting the hardness ratio of IRs/DCs is put forward.
