权力和地位对自利行为的影响及其机制

权力和地位对自利行为的影响不同。权力能够降低认知性观点采择水平,进而使个体更加关注自身利益;地位能够提升认知性观点采择水平,进而使个体推测他人思想与感受,考虑他人利益。然而,权力和地位通过认知性观点采择对自利行为的影响可能受到情境性质的调节。今后的研究应该对这些关系和解释进行验证,探索共情性关心的中介作用,以及权力和地位影响认知性观点采择的调节变量;探究权力和地位拥有者对群体内、外他人的自利行为差异;探讨权力和地位的交互作用对自利行为的影响。     

Assessment of Differential Rater Functioning in Latent Classes with New Mixture Facets Models

Multifaceted data are very common in the human sciences. For example, test takers' responses to essay items are marked by raters. If multifaceted data are analyzed with standard facets models, it is assumed there is no interaction between facets. In reality, an interaction between facets can occur, referred to as differential facet functioning. A special case of differential facet functioning is the interaction between ratees and raters, referred to as differential rater functioning (DRF). In existing DRF studies, the group membership of ratees is known, such as gender or ethnicity. However, DRF may occur when the group membership is unknown (latent) and thus has to be estimated from data. To solve this problem, in this study, we developed a new mixture facets model to assess DRF when the group membership is latent and we provided two empirical examples to demonstrate its applications. A series of simulations were also conducted to evaluate the performance of the new model in the DRF assessment in the Bayesian framework. Results supported the use of the mixture facets model because all parameters were recovered fairly well, and the more data there were, the better the parameter recovery.     

Tower of London: What Level of Planning Does it Measure?

We examined which of two levels of planning, namely action and operations planning, are involved in Tower of London (TOL). One hundred nine university students (79 females; mean age = 20.81 years) from China were assessed on measures of action planning (Crack the Code), operations planning (Planned Connections, Planned Codes, Matching Numbers), and on TOL. The results of factor analysis showed first that TOL, scored as total number of correct responses, had a split loading on action and operations planning. TOL, scored as first move time, loaded on the same action planning factor represented by Crack the Code first move time. These findings suggest that different TOL scores may capture different levels of planning. The implications of these findings especially for clinical diagnosis and rehabilitation are briefly discussed.     

运动技能水平与躯体感觉输入对运动表象的影响

运动表象质量与运动技能水平有关,运动表象质量随着运动技能水平的提高而上升。器械使用可使人脑产生可塑性改变,使用者会将器械纳入身体图式。然而,两者影响运动表象的神经心理机制还不清楚。本研究采用功能性磁共振成像探析篮球运动员与新手在不同持球条件下表象投篮时脑功能活动的差异。结果表明运动员表象质量较好,镜像神经系统激活高于新手;持球条件下运动员表象质量显著高于不持球条件下,镜像神经系统激活程度显著低于不持球条件下。研究说明持器械可以显著提高运动员的表象质量,器械使用带来镜像神经系统的可塑性变化。     

New polytypes of long-period stacking ordered structures in a near-equilibrium Mg97Zn1Y2 alloy

By atomic-scale high-angle annular dark-field scanning transmission electron microscopy, the long-period stacking ordered (LPSO) structures in a near-equilibrium Mg₉₇Zn₁Y₂ (at.%) alloy have been characterised. In addition to 18R and 14H, new polytypes of LPSO structures are analysed and determined as 60R, 78R, 26H, 96R, 38H, 40H, 108H and 246R. All of these LPSO structures feature AB′C′A building blocks with two Mg layers and three Mg layers sandwiched between them. The Bravais lattices and space groups of new polytypes of LPSO structures were easily determined via the newly introduced method. A structural relationship between the LPSOs is proposed.     

贫富群体心理融合中的“道德突显现象”

目的:以中国传统的财富观和刻板印象内容模型为理论基础,采用实验法,探讨道德、热情和能力在贫富心理融合中的作用。方法:613名社会人士参加了实验,两个实验分别操作了穷人和富人身份。结果:无论对穷人还是富人的心理融合,道德、热情和能力三个因素对心理融合的主效应都显著,且道德因素的效应值最大。这表明,人们对贫富群体的心理融合存在"道德突显效应",即道德因素在人们对穷人和富人的心理融合过程中起到重要作用。     

事必躬亲还是权力共享？内隐追随理论视角下的领导者授权行为研究

本文基于内隐追随理论,探讨了领导者的积极追随原型与追随者的积极追随特质的匹配情形如何形塑领导者的授权行为。基于广东省2家食品企业的226份上下级配对数据,采用多项式回归和响应面分析技术发现：当追随者的积极追随特质与领导者的积极追随原型相匹配时,追随者能够成为领导者的“意中人”。面对“意中人”,领导者将展现更多的授权行为。在匹配情况下,高-高匹配时的领导者授权行为高于低-低匹配的情形。     

贝施特和智顗论"恶"的宗教价值--兼谈宗教中的"善恶"观念

谈"善"论"恶"是宗教中的永恒话题,但宗教中的"善恶"并非仅仅是伦理学意义上的善恶,而是包括宗教修持意义上的"善恶".一般而言,"善"是有助于宗教修持的,但是贝施特和智顗却分别站在犹太教和中国佛教天台宗的立场揭示了"恶"对于宗教修持的积极作用,阐明了"恶"的宗教价值,尽管他们所说的"恶"的内涵不同.其中贝施特主张"恶"中分有"善"的神性,通过"恶"可以回归上帝;智顗主张"恶"中本具"善"的"实相",通过观"恶"的"烦恼心"可以达到解脱.可以说,在"恶"的宗教价值这个问题上,贝施特和智顗进行了一次跨宗教的对话.

中医院市场定位的两难选择及其对策

中医院的市场定位处于两难选择之中:中医药技术的潜在优势与现实局限性的矛盾、中医院管理者的价值取向与现实窘况的矛盾、中医院发展历史沉淀与市场竞争的矛盾、政府的中医药政策自身存在的矛盾等。这些矛盾涉及多方行为和利益主体,必须深化改革,以实现中医院的良性发展。
