城市弱势群体伦理关系现状的调查分析

在当今中国社会的伦理范型由传统到现代的转型过程中,社会弱势群体的伦理观念、道德风尚的转变是一个重要方面.本文基于问卷调查和理论分析,认为目前城市中社会弱势群体的伦理关系基本延续了"传统",但伦理关系的"性质"则趋向于"现代".在此基础上,着重探讨了弱势群体与其他群体、与社会发生伦理冲突的潜在风险及其产生的原因,并提出了相应的伦理对策.

Mixture Factor Analysis for Approximating a Nonnormally Distributed Continuous Latent Factor With Continuous and Dichotomous Observed Variables

Mixture factor analysis is examined as a means of flexibly estimating nonnormally distributed continuous latent factors in the presence of both continuous and dichotomous observed variables. A simulation study compares mixture factor analysis with normal maximum likelihood (ML) latent factor modeling. Different results emerge for continuous versus dichotomous outcomes. For dichotomous outcomes, normal ML path estimates have bias that worsens as latent factor skew/kurtosis increases and does not diminish as sample size increases, whereas the mixture factor analysis model produces nearly unbiased estimators as sample sizes increase (500 and greater) and offers near nominal coverage probability. For continuous outcome variables, both methods produce factor loading estimates with minimal bias regardless of latent factor skew, but the mixture factor analysis is more efficient. The method is demonstrated using data motivated by a study on youth with cystic fibrosis examining predictors of treatment adherence. In summary, mixture factor analysis provides improvements over normal ML estimation in the presence of skewed/kurtotic latent factors, but due to variability in the estimator relating the latent factor to dichotomous outcomes and computational issues, the improvements were only fully realized, in this study, at larger sample sizes (500 and greater).     

Relative Leader–Member Exchange Within Team Contexts: How and when Social Comparison Impacts Individual Effectiveness

A multilevel model was developed to examine how and when a focal individual's leader–member exchange (LMX) relative to the LMXs of coworkers within the team (relative LMX, or RLMX) influences individual in‐role performance, organizational citizenship behavior (OCB), and job satisfaction. Results, based on a sample of 275 leader–member dyads within 35 teams of a beverage company, largely supported the hypotheses. Specifically, using multilevel polynomial regression analyses, the results showed that self‐efficacy partially mediated the relationship between RLMX and in‐role performance and job satisfaction, and fully mediated the relationship between RLMX and OCB. Furthermore, the results demonstrated that team identification attenuated RLMX's direct effect on self‐efficacy, and indirect effects on in‐role performance and OCB and team supportive behavior attenuated RLMX's direct effect on self‐efficacy and indirect effect on in‐role performance.     

老年非小细胞肺癌治疗中存在的问题

肺癌已成为危害人类健康和导致死亡的最主要疾病,其中一半以上发生在老年人,且大部分为确诊时已为晚期,针对这些患者的诊断和治疗还存在很多误区,因多病并发所致的诊断延误、因恐惧所致的逃避、以及因对药物的过度依赖而对患者心理因素的忽视等,致使部分老年肺癌患者不能及时得到合理的治疗,值得引起临床医师的重视.     

Effects of a ‘Learn to Think’ intervention programme on primary school students

Background. Methods for teaching thinking may be described as out‐of‐context or infusion. Both approaches have potential to raise students’ general cognitive processing ability and so raise academic achievement, but each has disadvantages. Aims. To describe and evaluate a theory‐based learn to think (LTT) curriculum for primary school students, which draws on the strengths of both out‐of‐context and infusion approaches. Sample. One‐hundred and sixty‐six students in three classes of Grade 1 (6+ years old), Grade 2 (7+ years old), and Grade 3 (8+ years old) in a primary school in Shanxi province, China, randomly ascribed to experimental (90) and control (76) groups. Methods. All students were pre‐tested for non‐verbal intelligence and academic achievement. Experimental students followed the LTT curriculum (one activity every 2 weeks) for 4 school years. All were post‐tested on three occasions for thinking ability and four times for academic achievement. Results. Grade 1 and Grade 2 students showed effects of LTT from 1 year after their start and increasing: on thinking ability d= .78–1.45; on Chinese d= .68–1.07; on maths .58–.87. Grade 3 students showed effects from 6 months after their start: on thinking ability .90–1.37; Chinese .77–1.32; maths .65–1.29. The effects were concentrated in students in the middle band of initial ability. Conclusions. A curriculum for teaching thinking based on a structured theoretical model that combines elements of out‐of‐context and infusion methods has been shown to have long‐term far transfer effects on students’ thinking ability and academic achievement. More work is needed to meet the needs of a wider range of abilities.     

成就目标：理论、应用及研究趋势

成就目标理论是当前教育领域有关学生成就动机最为活跃的研究热点之一。20世纪中后期Weiner在整合动机理论和归因理论的基础上提出了成就目标理论。之后,Dweck等学者对成就目标的概念、分类及动机模式进行了大量研究。成就目标理论具有很好的发展前景,并在学校教育、体育运动和生涯发展等领域得到广泛的应用。未来研究应强调成就目标的动态性与多维性,注重成就目标的性别差异和社会期许效应,运用多元化方法以提高成就目标研究的外部效度,拓宽研究对象以增强成就目标的应用性研究,更加关注情绪情感与成就目标之间的关系。
