Mechanically driven alloying forces in the fabrication of a Cr–Zr nanocomposite

A highly supersaturated nanocrystalline Cr–25?wt% Zr alloy has been prepared by mechanical alloying of elemental crystalline powders. High-purity powders of Cr and Zr were milled for up to 20?h. The development of the microstructure was investigated by X-ray diffraction (XRD) and scanning electron microscopy. XRD patterns confirmed complete alloying of the Zr and Cr. The contribution of grain boundaries, the chemical potential of a solute atom induced by dislocations, and the elastic strain energy arising from the different sizes of Cr and Zr atoms have been calculated. The alloy formation is discussed with respect to the thermodynamic conditions of the material. The role of internal strains and stored enthalpies by dislocations on solute atoms is the major mechanical driving force for alloying and this is critically assessed in this article.     

消费行为领域中的调节定向

调节定向理论(Higgins,1997)超越传统享乐主义动机,区分出“促进”和“预防”两种调节性动机系统,近年已成为消费行为领域的研究热点之一.调节定向影响着消费者购物决策整个过程,受被试因素(文化背景、自我建构)、刺激因素(信息框架、解释水平、非言语线索、商品属性)和情境因素(决策时间距离、任务操纵)的影响,通过直接作用、调节关联效应和调节匹配效应三种途径决定信息的说服效果,并且受到精细加工可能性的调节.管理者应特别注意具体营销情境中的调节定向,合理利用调节匹配效应.未来研究应关注调节投入理论、调节定向的前因变量以及同网络购物情境相结合,并探索如何削弱预防定向对营销的不利影响.     

The importance of social and ideal social dimensions in self‐congruity research

Chronic or situational self‐construal moderates the effects of four self‐congruity (SC) dimensions (i.e., actual, ideal, social, and ideal social) on brand evaluations. Past research has mainly focused on the actual and ideal SC effects; these effects have been found to be stronger than the social and ideal social SC effects. However, the findings of past research are based on samples from individualistic cultures. Individualists have a dominant independent self‐construal. We conduct two experiments to show that the social and ideal social SC effects are stronger than the actual and ideal SC effects for individuals with a dominant interdependent self‐construal. In Study 1, using samples from collectivistic cultures, four SC effects are compared. In Study 2, we examine how primed self‐construal, whether independent or interdependent, impacts the four SC effects. This research documents the importance of the social and ideal social dimensions in SC research.     

中学生职业兴趣的结构及其特点

参考国内外有关资料,设计适合我国中学生的职业兴趣测验。对309名在校中学生测查结果的因素分析表明,共存在六个因素,可以解释为现实型（R)、研究型 (I)、艺术型 (A)、社会型 (S)、经营型 (E)和常规型(C),这与霍兰德的六种职业类型一致。但六种兴趣之间的关系与霍兰德的职业六边形不完全一致。进一步的分析表明,初三以上的中学生的职业兴趣已出现明显分化。年级和性别因素对职业兴趣均有显著影响,年级与性别的交互作用不显著。     

中学生学业成就归因与学习动力的相关研究

用自编问卷对913名中学生学业成就归因和学习动力状况进行了调查,发现: (1)整体上看中学生较多使用内在原因和可控原因解释自己的学习成绩; (2)不同性别和不同年级学生有不同的归因倾向; (3)归因倾向与学习动力有明显联系,使用因子分析法得到“自挫因子”对学习动力有很大的消极影响。本文还就如何进行归因训练进行了讨论。     

诗歌与禅宗的会通观

作为一种抵达艺术与人生至境的独特修持方法，诗与禅秉持“悟”、“妙悟”而抵达般若妙境。禅宗不藉文字、否弃概念，通过对思维定势的消解而超越对立，以情尘意垢的遣除而洞见自性本心，其进入诗学领域，对诗歌发生的艺术思维与个体审美心理体验产生了深刻的影响，它自见本性、直指本心的超验意识，与文艺创造活动圆融、会通。     

张景岳医易学思想新论

张景岳医易学思想中的两个重要问题,一是关于外易与内易及其相互之间的关系;二是通过对神与机、鬼与神、升与降等范畴的论述,提出了一个医易学的心理平衡系统.这两点都是发前人所未发,值得进行深入探讨.     

医闹种类、特征、危害与成因对策研究

通过典型案例综合分析了“武攻式医闹”、“文攻式医闹”和“文武式医闹”的各自特征以及“多元化地发展”和“边打击边反弹”的总体特征,提出医闹成因分析需要对其滋生背景和盛行原因区分思考,在对其严重危害、滋生背景和盛行原因分别剖析的基础上,较系统地提出了根治对策.     

民间信仰遏制外来宗教渗透的个案研究

本文以闽西客家村庄涧村为个案,探究其民间信仰在维系农民生活理想、满足他们(特别是其中的弱势者)的心理需求等方面所发挥的功能,进而指出民间的传统信仰不仅在弘扬中华文化传统及缓解社会问题方面具有战略意义,而且对于遏制海外势力的宗教渗透和邪教的传播具有明显的作用。     

Stereotype activation is unintentional: Behavioural and event‐related potenials evidence

In this study, a priming Stroop paradigm was used to determine whether stereotype activation is unintentional. Priming conditions (priming/no‐priming) and the relationship between priming and target (consistent/inconsistent/no‐relation) were the independent variables; accuracy, reaction time and N400 amplitude were used as dependent variables. The reaction time revealed that stereotype activation is, to some extent, unintentional. Furthermore, the event‐related potenial (ERP) results showed that N400 amplitude was larger for inconsistent conditions than for consistent conditions. This result supported the notion that stereotype activation is an unintentional and automatic process.
