Plastic stability of bimetals composed of Ti-based metallic glass composite and pure titanium

The plastic stability of bimetals composed of a Ti-based metallic glass composite (MGC) and a pure titanium (PT) under tension has been investigated. The results reveal that the plastic stability of the MGC/PT bimetal is strongly dependent on the thickness fraction of the MGC: when the thickness fraction of the MGC decreases to a critical value, a homogeneous plastic deformation occurs in the MGC/PT bimetals, i.e. the strain localization and necking of the MGC is effectively suppressed. This unique phenomenon is explained using the normalized strain-hardening rate, and the quantitative relationship between the normalized strain-hardening rate of the MGC/PT bimetals and the thickness fraction of the MGC is thereby established.     

关系密切程度以及思维方式和决策风格对风险偏好的影响

研究目的:探讨救援决策者与被救援者的关系密切程度以及思维方式与决策风格对风险偏好的影响。研究方法:实验一采用3(关系密切程度:高、中、低)×2(思维方式:直觉性、分析性)两因素混合实验设计,被试68名;实验二采用3(关系密切程度:高、中、低)×2(思维方式:直觉性、分析性)×2(决策风格:直觉型、分析型)三因素混合实验设计,被试93名。研究结果:(1)救援决策者与被救援者的关系密切程度越高,风险偏好越高;(2)直觉性和分析性思维方式之间的风险偏好无显著差异;(3)直觉型决策风格的风险偏好显著高于分析型;(4)关系密切程度与思维方式的交互作用显著,具体而言,采用直觉性思维方式时,关系密切程度的效应显著,关系密切程度越高,风险偏好越高;采用分析性思维方式时,关系密切程度的效应不显著。结论:直觉与风险偏好的关系更密切。面对关系亲密的被救援者,决策者采用直觉性思维方式时的风险偏好较高。     

西方哲学心智转向对心理学的影响

心智哲学是20世纪中末期西方哲学所发生的继语言(义)学转向和语用学转向之后的一次重要转向,它为心理学提供了新的元理论和方法论。(1)为心理学提供了"心智-语言-世界"新的世界观;(2)从哲学角度对人的心理进行了探讨,促进了哲学与心理学的结合并互哺;(3)促使人们对"人是什么"重新审视与理解;(4)引发了对以往心理学尤其是主流心理学的基石——身心二元论的质疑;(5)催生了第二代认知科学、活动主义、情境认知等新取向的兴起。它对心理学有很大启示:第一,人工智能、动物研究等研究是有限度的;第二,应重视身体的作用;第三,应重视人的意向性,注重隐喻分析;第四,应关注人的存在,尤其是生命的意义。     

高校教练家长式领导行为与运动员精神:有中介的调节效应

采用家长式领导行为问卷、运动价值观问卷、运动动机问卷和运动员精神问卷,对495名高校高水平运动员进行调查,以探讨教练家长式领导行为对高校高水平运动员的运动员精神的影响,及其内在的作用机制。结果表明:(1)家长式领导行为对运动员精神有显著的正向影响,运动动机在其中具有部分中介作用;(2)运动价值观在家长式领导行为与运动动机之间具有正向的调节作用,即运动价值观得分越高,这种正向关系也越强;(3)运动价值观对家长式领导行为与运动员精神关系的调节作用,是部分地通过运动动机为中介而产生。     

儿童状态社会创造性的跨文化研究:基于中美文化的比较

从中国和美国中部地区选取小学儿童236人,采用状态社会创造性开放问卷和教师领导方式结构式问卷考察了儿童状态社会创造性的文化差异及其与教师领导方式的关系。结果表明:(1)总体上,美国儿童在社会性问题解决中表现出较强的流畅性和变通性等创造性思维品质,但中国儿童表现出较强的适当性、有效性和冒险性等社会适应和人格状态;(2)状态社会创造性总体上存在着国别与年级之间的交互作用,美国的四年级儿童状态社会创造性得分显著高于五年级儿童;(3)教师领导方式的各个维度均不存在显著的预测作用。中美儿童的状态社会创造性既有相似之处又有不同之处。     

负面评价恐惧的性别差异:基于内隐和外显测量的比较

从内隐和外显两种角度探讨负面评价恐惧的性别差异。采用简式内隐联系测验(BIAT)和简明负面评价恐惧量表(BFNES)两种测量方法,实验共72名被试,每名被试先进行简式内隐联系测验,再完成简明负面评价恐惧量表,并借鉴不同方法对两种测量结果进行分析。结果发现:(1)被试的内隐负面评价恐惧与外显负面评价恐惧不存在显著相关,结果产生实验性分离;(2)负面评价恐惧不存在显著性别差异;(3)但有趣的是,不同性别被试内隐和外显负面评价恐惧的分离状况存在显著差异,其中男性的外显负面评价恐惧低于内隐负面评价恐惧,而女性的结果刚好相反,其外显负面评价恐惧高于内隐负面评价恐惧。这些结果表明被试的内隐和外显负面评价恐惧虽然不存在显著性别差异,但不同性别被试的内隐负面评价恐惧和外显负面评价恐惧内部存在不同的组合状况。     

Expressive writing promotes self‐reported physical,social and psychological health among Chinese undergraduates

The present study examines the efficacy of expressive writing among Chinese undergraduates. The sample comprised of 74 undergraduates enrolled in a 9‐week intervention (35 in experimental class vs. 39 in control class). The writing exercises were well‐embedded in an elective course for the two classes. The 46‐item simplified Chinese Self‐Rated Health Measurement Scale, which assesses psychological, physical and social health, was adopted to measure the outcome of this study. Baseline (second week) and post‐test (ninth week) scores were obtained during the classes. After the intervention on the eighth week, the self‐reported psychological, social and physical health of the experimental class improved. Psychological health obtained the maximum degree of improvement, followed by social and physical health. Furthermore, female participants gained more psychological improvement than males. These results demonstrated that the expressive writing approach could improve the physical, social and psychological health of Chinese undergraduates, and the method can be applied in university psychological consulting settings in Mainland China.     

The associations between parenting styles and proactive and reactive aggression in Hong Kong children and adolescents

Previous research suggests that reactive and proactive aggression may be differentially related to family contextual (e.g. parenting practices) factors. However, the existing research has focused largely on children and adolescents from Western countries, and no study has examined the parenting–aggression association using a parenting style measure sensitive to Asian culture. In this study parenting styles (i.e. warmth, control and guan/training) and proactive and reactive aggression were assessed in a large sample of school children in Hong Kong, China (N = 4,175, mean age = 11.75). We found that: (a) both low warmth (in boys only) and guan (i.e. high expectation and close supervision, in both boys and girls) were associated with elevated parent‐reported proactive aggression, (b) high restrictive control (i.e. dominating and rejecting) was associated with high reactive aggression (in both boys and girls) based on parent‐ or child‐report data, and with high proactive aggression (in boys only) based on parent‐report data, and (c) guan was also positively associated with parent‐reported reactive aggression. Findings provide more information about the Parenting Inventory using a large Asian sample, and extend existing research on familial correlates of different types of aggression.
