肿瘤干细胞起源与鉴定方法研究现状

CSC理论使人们对恶性肿瘤有了一个全新的认识,为临床治疗提供了一个全新视角。该理论改变目前以全部癌细胞为目标的药物治疗策略,将使治愈肿瘤成为可能。分离和鉴定CSC是CSC靶向治疗的第一步。本文就CSC的起源和鉴定方法做一简要综述。     

组织政治知觉对组织认同的影响及工作投入的中介作用

以300余名中国大陆制造业企业的员工为被试,运用问卷调查方法和分层回归分析对组织政治知觉、组织认同和工作投入的关系进行了探讨。结果发现：（1）组织政治知觉对工作投入和组织认同有直接的消极影响;（2）组织政治知觉通过组织认同的中介对工作投入有间接的消极影响;（3）在组织政治知觉的三个子维度中,只有薪酬与晋升子维度对工作投入和组织认同具有显著影响。     

Group identity,ethnic separatism and multiple out‐groups: The Basque case

Within the context of the Basque Country in Spain we examined how ethnic (Basque) and national (Spanish) identification relate to the evaluation of Spaniards, Basques, Andalusians and Catalans. On a sample of adolescent participants we tested a structural equation model which considered identity content (Basque separatism) as a mediator of the relationship between group identifications and group evaluations. While Spanish and Basque identification were associated with a positive evaluation of Spanish and Basque in‐groups, respectively, the evaluation of out‐groups that are relatively similar to the in‐group were not affected by identification. In contrast, dissimilar out‐groups tended to be evaluated more negatively by higher in‐group identifiers. Basque separatism mediated the negative relationship between Basque identification and the evaluation of Spaniards and of Andalusians as a prototypically Spanish subgroup. It is concluded that identification relates differently to the evaluation of different out‐groups, and that the ideological content of identity plays an important role in determining intergroup relations.

教师组织认同、工作满意感与情感承诺的关系

组织认同是社会认同的一种特殊形式,是与组织具有一致性或从属于组织的知觉。通过对545名教师施测Mael和Tetrick组织认同问卷、工作满意感问卷和情感承诺问卷,结果发现:(1)个体的组织认同水平能够正向的预测其工作满意感水平;(2)个体的组织认同水平能够正向的预测其情感承诺水平;(3)个体的工作满意感能够部分中介其组织认同对于情感承诺的预测作用。     

高校教师知识共享态度的相关研究

以151名高校教师为测查对象,采用“高校教师知识共享问卷”等研究工具,考察工作态度、组织特征等因素与高校教师知识共享态度之间的关系.结果发现:(1)文、理科教师之间在避损性共享和人际性共享上存在显著差异;(2)组织认同、工作满意度、知识特性和学科与避损性共享存在显著相关;(3)组织认同、工作满意度、工作意义、工作奉献、组织特性和学科与人际性共享存在显著相关.研究表明,理科教师的共享态度较文科教师更为积极;知识共享除了与工作态度有关之外,也与软硬件环境有关.     

The faultline activation process and the effects of activated faultlines on coalition formation,conflict, and group outcomes

This research examines the effects of group faultline activation on coalition formation, conflict, and group outcomes. We distinguish between dormant faultlines (potential faultlines based on demographic characteristics) and activated group faultlines (members actually perceive subgroups based on the demographic characteristics) and hypothesize that while dormant faultlines do not automatically turn into active group divisions, a group’s entitlement configuration can activate divisions among group members. Study 1 was a construct validity study to verify the psychometric properties of the activated group faultline measure and explain its connection to other process variables. In Studies 2 and 3, we tested our hypotheses and found that groups with activated faultlines were more likely to form coalitions, have high levels of group conflict, and lower levels of satisfaction and group performance than dormant faultline groups. Furthermore, team identification moderated the effects of activated faultlines on group processes such that a strong workgroup identity decreased the likelihood that activated faultlines led to coalition formation and conflict.     

Does identification predict community involvement? Exploring consequences of social identification among the Jewish minority in Poland

Previous research indicated that people who strongly identify with their own group are more involved in the group's actions. The current study examines the relation between three dimensions of group identification (affect, ties, centrality) and forms of community involvement among members of the Jewish minority in Poland. The strength of ingroup ties predicted involvement in the ethnic minority community. The link between identification and involvement was mediated by the cultural dominance. The reported study was the first quantitative survey of the Jewish community in post‐War Poland. Copyright © 2009 John Wiley & Sons, Ltd.     

声旁与笔画省略方式对形声字识别的影响

本研究通过两个实验,考察笔画省略方式和声旁对形声字识别的影响。实验一采用命名任务考察了声旁和三种笔画省略方式（省前、略后、不省）对左右结构形声字识别的影响。结果表明存在笔画顺序效应和声旁位置效应,并发现略后的笔画中有声旁,笔画顺序效应会消失。这说明声旁的作用抵消了笔画顺序效应,体现了声旁在形声字识别中的重要作用;实验二在实验一的基础上,采用上下结构的形声字,实验结果表现出了相同的趋势,且更加显著。     

Comments on Plantinga’s Argument of Transworld Identity

Plantinga’s conception of possible worlds is problematic in one sense: it relies on the prior idea of modality. His strategy for resolving the puzzle of transworld identity is significant in the metaphysical sense but fruitless in the epistemological sense because world-indexed properties cannot be used as effectively in epistemic practice as their counterparts, i.e., space- and time-indexed properties. His isolation of transworld identification from transworld identity is unconvincing. This paper argues that the intelligibility of modal discourse and reference is the essence of transworld identity. It is also proved that transworld identification is the epistemic ground of such intelligibility. Hence, the transworld identification problem is the epistemological foundation of the transworld identity problem, and there must be a comprehensive answer to the former.
