Causal attribution for interfirm contract violation: a comparative study of Chinese and American commercial arbitrators

In this study, the authors examined differences between Chinese and American commercial arbitrators. They predicted and found that Chinese arbitrators make higher awards for interfirm contract violations than Americans. This difference is partially explained by differences in attributions. Prior theory suggests, and the authors found, that the Chinese tend to have more internal attributions for events when observing group actions. When evidence provided to arbitrators is mixed (evidence is provided for both internal and external attributions), Chinese-American differences in awards become even stronger.

对低危前列腺癌治疗策略的再认识及思考

前列腺癌被认为是老年男性中最常见的恶性肿瘤.近年来,PSA筛查技术的广泛使用提高了前列腺癌的检出率.但许多低危的非致命性的前列腺癌患者却承受着过度治疗所带来的毒副反应风险.作者就当前用于减少低危前列腺癌过度治疗的新策略进行描述,如观察等待和主动监测策略,并指出癌症的过度治疗是很普遍的现象.未来需要发展更多的对恶性肿瘤进行最优治疗的策略.     

普通高中实施选修课的心理认可度及其影响因素——基于宁波市教师与学生群体的调查分析

以宁波市三种类型六所普通中学为样本,以学生群体和教师群体为对象,采用问卷评定法,以心理认可度为指标,探讨了普通中学师生对于实施选修课制度的主观评价及其相关因素.结果发现：整体而言,学生和任课教师对宁波市普通高中实施选修课的心理认可度较高;存在的主要问题,是学生对选修课学习效果的认可度较低,而教师对学校开展选修课的教学条件的认可度较低,且认为实施选修课制度的外部阻力较大;特色类和融通类学校落实选修课制度的观念性阻力较大;中老年教师对开设选修课的适应性较低.进一步完善选修课制度,需要从教师、学校和政府三个方面形成合力,共同推动旨在促进学生个性化发展的选修课制度的健康发展.     

基于双眼视差探讨深度知觉信息对背景线索效应的影响

背景线索效应是由重复场景导致搜索效率提高的现象。以往研究发现三维场景下能获得背景线索效应,但对三维场景下深度知觉线索信息如何影响空间场景提供有效线索引导注意仍缺乏实证研究。本研究以矩阵刺激为材料,通过设置不同的刺激项目水平数探讨深度知觉线索对背景线索效应的影响模式。结果发现:(1)在场景布局由较少项目构成时,深度知觉线索提供目标与刺激项目的有效联结,获得背景线索效应;(2)当刺激项目水平达到一定程度时,深度知觉线索增加了背景线索任务的搜索难度,干扰了重复场景中的背景信息对注意的指导性加工,背景线索效应消失。研究结果为三维场景下深度信息对空间场景中注意引导加工的影响提供了证据。     

The Data Envelopment Analysis and Equal Weights/Minimax Methods of Composite Social Indicator Construction: a Methodological Study of Data Sensitivity and Robustness

In the construction of composite or summary social indicators/indices, a recurrent methodological issue pertains to how to weight each of the quality-of-life/well-being components of the indices. Two methods of composite index construction that have been widely applied empirically in recent decades are Data Envelopment Analysis (DEA), which is based on an optimization principle, and the equal weights/minimax (EW/MM) method, which has been shown to have minimax statistical properties in the sense that it minimizes maximum possible disagreements among individuals on weights. This paper applies both of these methods to two empirical datasets of social indicators: 1) data on 25 well-being indicators used in the construction of state-level Child and Youth Well-being Indices for each of the 50 U.S. states, and 2) data on indicators of life expectancy, educational attainment, and income used in the construction of the United Nations Human Development Programme’s Human Development Index (HDI) for 188 countries. In these empirical contexts, we study issues of measurement sensitivity of the EW/MM and DEA methods to the numbers of indictors used in the construction of the composite indices and corresponding issues of robustness. We find that the DEA method is more sensitive to the numbers of component indicators than the EW/MM method. In addition, the composite indicators formed by the EW/MM and DEA methods become more similar as the numbers of indicators in the composites decreases. We also apply Chance-Constrained DEA method to reclassify countries in the HDI dataset by levels of human development. The resulting human development groupings of the DEA composite indices have a large overlap with those of the HDI in the Human Development Reports, which are based on fixed cut-off points derived from the quartiles of distributions of the HDI component indicators.

     

留守儿童心理虐待与攻击行为：心理弹性和人际敏感的链式中介作用

为探究留守儿童心理虐待与攻击行为之间相关关系,采用修订后的儿童心理虐待量表、留守儿童心理弹性问卷、SCL-90中的人际关系敏感分量表和Buss-Perry攻击行为量表对754名留守儿童进行调查。结果发现：（1）心理虐待对留守儿童心理弹性具有显著负向预测作用,对人际敏感和攻击行为具有显著正向预测作用。（2）心理弹性和人际敏感分别在心理虐待与攻击行为之间起到部分中介作用。（3）心理弹性和人际敏感在心理虐待与攻击行为之间起到链式中介作用。
