Ethnic and mainstream social connectedness, perceived racial discrimination, and posttraumatic stress symptoms

Carter (2007) proposed the notion of race-based traumatic stress and argued that experiences of racial discrimination can be viewed as a type of trauma. In a sample of 383 Chinese international students at 2 predominantly White midwestern universities, the present results supported this notion and found that perceived racial discrimination predicted posttraumatic stress symptoms over and above perceived general stress. Furthermore, Berry (1997) proposed an acculturation framework and recommended that researchers advance the literature by examining the moderation effects on the association between racial discrimination and outcomes. The present results supported the moderation effect for Ethnic SC (i.e., social connectedness in the ethnic community), but not for Mainstream SC (i.e., social connectedness in mainstream society). A simple effects analysis indicated that a high Ethnic SC weakened the strength of the association between perceived racial discrimination and posttraumatic stress symptoms more than a low Ethnic SC. Moreover, although Mainstream SC failed to be a moderator, Mainstream SC was significantly associated with less perceived general stress, less perceived racial discrimination, and less posttraumatic stress symptoms.     

The Concerns about Counseling Racial Minority Clients scale

The purpose of this study was to develop and validate the Concerns about Counseling Racial Minority Clients (CCRMC) scale among counselor trainees. Sample 1 was used for an exploratory factor analysis and confirmatory factor analysis. Four factors were identified, Managing Cultural Differences (α = .82), Offending or Hurting Clients (α = .87), Biased Thoughts and Behaviors (α = .81), and Client Perceptions (α = .77). The coefficient alpha for the CCRMC was .90. The results support the validity of the scale. The scores on the CCRMC and its subscales have positive associations with fear of negative evaluation from others (r = .19 to .40) and negative associations with general counseling self-efficacy (r = -.30 to -.46) and multicultural intervention self-efficacy (r = -.30 to -.64). The CCRMC significantly predicted fear of negative evaluation, session management self-efficacy, and multicultural intervention self-efficacy over and above multicultural social desirability. The validity evidence was not different between White and minority graduate trainees. In Sample 2, the estimated 1-week test-retest reliabilities ranged from .75 to .96 for the CCRMC and its four subscales.     

CAML—Maximum likelihood consensus analysis

Consensus analysis enables estimation of individual differences in competencies and response tendencies when answer keys to dichotomous forced-choice questions are unknown. CAML, a set of functions written in R, implements maximum likelihood estimation for the general Condorcet model that underlies consensus analysis. CAML avoids problems of alternative approaches that have often rendered consensus analysis impractical or unfeasible in the past. It provides (1) measures of model fit, (2) a measure of consensus, (3) point and interval estimates of competencies and response tendencies, and (4) an estimate of the unknown answer key. The present article describes the general Condorcet model, the CAML algorithms, and the handling of the software. In addition, the validity of CAML results is tested in a recognition memory study using selective experimental manipulations of the parameters. The results show that CAML works very well in practice and provides valid estimates of competencies, response tendencies, and answer keys.     

初中流动儿童的内隐群体偏爱、社会支持及其对学校适应的影响

以群体偏爱的IAT测验为实验材料,结合社会支持和学校适应问卷,考察初中流动儿童在内隐群体偏爱、社会支持上与本地儿童之间的差异,并探讨这两种变量对流动儿童学校适应的影响.结果表明：（1）流动儿童存在内隐外群体偏爱,对自身所属群体表现出内隐的消极认同;本地儿童存在内隐内群体偏爱,对流动儿童具有内隐的消极认知;（2）流动儿童在父亲、教师以及同性朋友的社会支持上显著差于本地儿童;（3）在对流动儿童学校适应的影响上,社会支持的主效应显著,内隐群体偏爱和社会支持的交互作用显著;高内隐群体偏爱组中,高社会支持流动儿童的学校适应优于低社会支持儿童.     

The Relationships Between Family Financial Stress,Mental Health Problems,Child Rearing Practice,and School Involvement Among Taiwanese Parents with School-Aged Children

This study examined the relationships between family financial stress, mental health problems, child rearing practice, and school involvement using a sample of 431 parents with children in grades 1–4 from one elementary school in a rural area of Taiwan. Financial stress was hypothesized to be associated with parental mental health problems, which in turn were expected to be linked to poorer child rearing practice and less parental involvement in school. Structural equation models were constructed and tested in a stepwise manner. Results showed that financial stress was significantly associated with higher mental health problems, poorer child rearing effort, and decreased parental school involvement while parents’ mental health problems were not significantly associated with their child rearing efforts or involvement in school. These findings suggest that the impact of family financial stress on Taiwanese parents’ child rearing practice is largely direct rather than mediated through their mental health problems.     

Preferential Semantics using Non-smooth Preference Relations

This paper studies the properties of eight semantic consequence relations defined from a Tarski-logic L and a preference relation ? . They are equivalent to Shoham’s so-called preferential entailment for smooth model structures, but avoid certain problems of the latter in non-smooth configurations. Each of the logics can be characterized in terms of what we call multi-selection semantics. After discussing this type of semantics, we focus on some concrete proposals from the literature, checking a number of meta-theoretic properties and elaborating on their intuitive motivation. As it turns out, many of their meta-properties only hold in case ? is transitive. To tackle this problem, we propose slight modifications of each of the systems, showing the resulting logics to behave better at the intuitive level and in metatheoretic terms, for arbitrary ? .     

道德型领导者得到了什么？道德型领导、团队平均领导-部属交换及领导者收益

道德型领导是新近提出的一种领导理论,大量研究证实这种领导方式会对员工和组织带来积极影响。然而,在领导过程中处于主体地位的领导者从中获得了什么收益却较少受到关注。以50个工作团队的248名员工为研究对象,本研究基于社会交换理论考察了道德型领导与个体层次和团队层次上领导者收益的关系及其作用过程。跨层次分析结果表明：(1)道德型领导对个体层次的员工对领导的认知信任和情感信任,以及团队层次的团队绩效和领导者绩效均有显著正向作用;(2)团队平均领导-部属交换中介了道德型领导与下属对领导者的认知信任、情感信任以及团队绩效的关系,但在道德型领导与领导者绩效关系间无显著中介作用。本文揭示了道德型领导者在领导过程中获得的“收益”以及团队层次社会交换的中介作用,为道德型领导和团队社会交换的研究提供了启示。     

The Trophy Effect

By extending a typical endowment effect experiment with the possibility of winning the endowment in a real effort contest, we found two reinforcing effects that led to a complete market failure. Subjects who won the item in the effortful competition had a very high willingness to accept (trophy winner effect). By contrast, subjects who were not successful had an extremely low willingness to pay for the same item (trophy loser effect). We disentangle different components of these effects and investigate the underlying emotional responses. Further, we analyze the duration of the effects and discuss economic implications.

A conceptualisation of task dimensions affecting escalation of commitment

People frequently continue an investment despite a negative outcome or sunk cost. Such irrational persistence in a losing course of action has been termed escalation of commitment. Although several explanations of escalation of commitment have been proposed, none of them accounts for all determinants that have been empirically demonstrated. Based on a review of previous research, a conceptualisation is introduced of how escalation of commitment is affected by 4 task dimensions: type and nontransparency of decision goal, nontransparency of sunk costs, time course of sunk costs, and accountability. A more inclusive theory that subsumes escalation of commitment is offered as an alternative that may be developed to account for the effects of the task dimensions.     

非数量视觉特征对数量感知的影响

以往许多研究探讨了各种视觉特征对数量判断任务的影响,但得出了不一致的结论.本研究依据信号检测论原理对刺激特征影响数量判断的方式进行考察.结果发现:刺激大小、形状和分布均匀度等因素可影响数量判断的反应标准,但不会影响辨别力;刺激聚集或组块会直接对数量判断的辨别力产生影响.结果表明,不同刺激特征对数量判断的影响方式存在差异.一方面,人类具有从刺激特征中直接抽取数量信息进行认知比较的能力;另一方面,刺激点聚集或组块可以直接影响被试的数量感知.此外,我们还推测,组块是通过改变客体表征的方式来影响数量感知的.
