Action orientation overcomes the ego depletion effect

It has been consistently demonstrated that initial exertion of self‐control had negative influence on people's performance on subsequent self‐control tasks. This phenomenon is referred to as the ego depletion effect. Based on action control theory, the current research investigated whether the ego depletion effect could be moderated by individuals' action versus state orientation. Our results showed that only state‐oriented individuals exhibited ego depletion. For individuals with action orientation, however, their performance was not influenced by initial exertion of self‐control. The beneficial effect of action orientation against ego depletion in our experiment results from its facilitation for adapting to the depleting task.     

Exploring correlations between positive psychological resources and symptoms of psychological distress among hematological cancer patients: a cross-sectional study

Hematological cancer patients experience high levels of psychological distress during diagnoses and intensive treatments. The aim of the present study is to explore the effects of positive psychological resources on depressive and anxiety symptoms in hematological cancer patients. This survey was conducted in a hospital during the period from July 2013 to April 2014. A total of 300 inpatients were recruited and finally 227 of them completed the questionnaires. Questionnaires included demographic and clinical variables, the Center for Epidemiologic Studies Depression Scale, the Self-Rating Anxiety Scale, the Life Orientation Scale-Revised, the General Perceived Self-Efficacy Scale, and the Resilience Scale-14. Results showed that the prevalence of depressive and anxiety symptoms was 66.1 and 45.8%, respectively. Both optimism (β = ?.479, p < .001) and resilience (β = ?.174, p < .05) were negatively associated with depressive symptoms, and optimism (β = ?.393, p < .001) was negatively associated with anxiety symptoms. However, resilience (β = ?.133, p > .05) was not significantly associated with anxiety symptoms, and self-efficacy was not significantly associated with depressive (β = ?.032, p > .05) or anxiety symptoms (β = ?.055, p > .05). The results suggest that hematological cancer patients who possess high levels of positive psychological resources may have fewer symptoms of psychological distress. The findings indicate that enhancing positive psychological resources can be considered in developing intervention strategies for decreasing depressive and anxiety symptoms.     

Developmental dynamics between reading and math in elementary school

Reading and math attainment develop during elementary grades. Questions remain, though, about the co‐developmental nature of the relation between reading and math. This study examined dynamic, longitudinal pathways between reading and math in first through fourth grades. Participants of the study were 554 academically at‐risk children (M_age at the first assessment point = 6.57 years; SD = 0.38) from Texas Project Achieve. Children were assessed utilizing the Woodcock‐Johnson–III reading and math measures. Results from dynamic bivariate latent change score models indicated unidirectional longitudinal coupling effects from reading to math. Specifically, average and high levels of reading performance were associated with subsequent gains in math growth, in particular for below average performing children in math. In contrast, low levels of reading performance had negligible or no amplifying influences on change in math growth. The nature of the dynamics was replicated even when controlling for nonverbal cognitive abilities. Results demonstrated that good reading skills pave the way for children to develop their math skills. Such findings underscore the importance of considering reading performance in treating math difficulties.     

贝叶斯推理的三重加工心智模型

自二十世纪60年代Edwards首次用实验研究人类推理是否遵循贝叶斯规则以来,国内外贝叶斯推理研究取得了长足的发展,但也出现了一些困境:对影响贝叶斯推理的客体因素和主体因素研究未成体系,解释理论莫衷一是。未来的研究应该重新审视客体与主体的关系,系统整合和多角度分析影响贝叶斯推理的因素,尝试以三重加工心智模型解释人类贝叶斯推理行为,并对以往的解释理论进行融合,从而更好地揭示人类不确定性决策的本质。     

领导授权行为的形成机制

领导授权行为通常被视为一种积极的领导行为类型。组织中管理者在授权实施过程中扮演着重要角色, 然而管理者出于维护威权等目的, 不想赋予员工自主权或相应资源的现象大量存在。鉴于此, 越来越多的学者开始探索领导授权行为的影响因素, 但目前研究较为零散, 亟待整合。研究发现：(1)更多的学者强调领导授权行为并非一种稳定的领导风格, 而是领导对不同下属所采取的差异化授权行为; (2)领导授权行为的影响因素可以分为环境因素、领导者因素以及员工因素; (3)领导成员交换理论、信任理论、社会认知理论与授权风险视角是解释领导授权行为形成的重要理论/视角。此外, 基于情境领导理论、CIP领导模型(魅力型-意识形态型-务实型)以及追随理论, 提出了领导授权行为影响因素的未来研究方向。     

关于不可化归的多态式量词句的CCG探析

广义量词理论对英语中一些特定的量词句进行分析,把其中两个单态式量词合并成一个多态式量词。Keenan证明了这个多态式量词的意义不能化归为两个单态式量词的意义,即多态式量词的意义不能从两个单态式量词的标准意义推演出来。Keenan的研究是很有价值的,但本文尝试从另外的角度思考,对汉语类似的多态式量化句进行个案处理,采纳组合范畴语法针对自然语言表层结构的词汇主义方法,遵循部分表达式的意义决定整体表达式意义的组合原则,从两个单态式量词的非标准意义推演出整个多态式量词句的量化意义。     

模态逻辑的集合论语义与互模拟不变性

含有命题变元的非良基集合能够被看作解释模态语言的模型。任给非良基集合a,一个命题变元p在a上真当且仅当p属于a。命题联结词的解释与古典命题逻辑相同。一个公式3A在a上真当且仅当存在集合b属于a,使得A在b上是真的。在一个集合中,属于关系被看作可及关系。在这种思想下,我们可以定义从模态语言到一阶集合论语言的标准翻译。对任意模态公式A和集合变元x,可以递归定义一阶集合论语言的公式ST(A,x)。在关系语义学下,van Benthem刻画定理是说,在带有唯一的二元关系符号R的一阶语言中,任何一阶公式等价于某个模态公式的标准翻译当且仅当这个一阶公式在互模拟下保持不变。因此,模态语言是该一阶关系语言的互模拟不变片段。同样,我们可以在集合上定义互模拟关系,证明van Benthem刻画定理对于集合论语义和集合上的互模拟不变片段成立,即模态语言是一阶集合论语言的集合互模拟不变片段。     

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.
