领悟社会支持在老年人的居住地情感认同和控制感之间的中介作用：一个纵向模型

本研究以281名老年人为研究对象,探讨了城市变迁中的老年人居住地情感认同、领悟社会支持和控制感的关系。研究使用居住地情感认同问卷、领悟社会支持问卷和控制感问卷为研究工具,采用每次间隔6个月,共3次的纵向追踪设计。结果发现：老年人的居住地情感认同可以正向预测领悟社会支持,老年人的领悟社会支持可以正向预测控制感,老年人的领悟社会支持在居住地情感认同和控制感之间起纵向中介作用。本研究结果揭示了城市老年居民的居住地情感认同对控制感的影响机制,也对提升城市老年居民的控制感具有一定的实践意义。     

元认知在画图表征策略和小学生数学问题解决能力中的中介作用

该研究采用自然实验和问卷调查法,对268名小学五年级学生进行画图表征策略训练,在此基础上根据策略学习情况筛选出掌握了该策略的218名学生,以这些学生为被试,探讨元认知在画图表征策略和小学生数学问题解决能力中的作用。结果表明:(1)策略学习后,小学生的画图表征策略水平和数学问题解决成绩均显著高于策略学习前。(2)画图表征策略通过元认知这一中介变量对小学生数学问题解决能力有显著的促进作用。     

对信息源的正向跟随倾向对决策效果的影响*

采用实验研究的方法,检验了二元选择情形下高准确率信息源(准确率x >50%)和低准确率信息源(准确率为1?x)对决策者预测效果的影响。尽管从逻辑上二者从准确率层面具有完全相等的信息价值,然而研究结果显示,决策者更倾向于采用正向跟随而非逆向跟随的方式处理来自信息源的信息。这导致低准确信息源的价值未能得以充分利用。学习和信息源的规范性对该信息处理倾向起到调节作用。     

Exaggerated grain growth and improved properties of Y1 Ba2 Cu3 O7-x by Pt addition

Abstract

Superconducting and mechanical properties of Y₁ Ba₂Cu₃ O₇ can be improved by the use of sintering aids. 0·2 wt% of finely divided laser-ablated platinum powder has been mixed with the parent material and produced a dense product with exaggerated grain growth and improved critical current density and Vickers hardness. At higher concentrations of platinum, while the mechanical properties are further improved, the increased density appeared to inhibit access of oxygen for the tetragonal to orthorhombic phase transition and the current density was reduced.     

论公共秩序——以奥林匹克赛事为例

人们通常将社会生活区分为公共生活、职业生活和私人生活三大领域,因而也就可以将社会生活秩序区分为公共生活秩序、职业生活秩序和私人生活秩序三种类型.     

Conceiving Possibility： Kierkegaard and Zhuangzi

This paper examines two notions of possibility conceived by Kierkegaard and Zhuangzi respectively. Kierkegaard conceives of it with appeals to the feeling of anxiety, while Zhuangzi deals with it in terms of a type of aesthetic feeling. Based on these distinctions, the paper goes further to explore two types of human existence as fostered by these two corresponding concepts of possibility. According to Kierkegaard, in order to maintain a connection with possibility, which would provide freedom to human existence, one must have faith in the redeemer bringing back possibility so that an individual human being might renew his or her choice ceaselessly. Zhuangzi, on the other hand, advises staying in the realm of nothingness and letting go of all things to avoid being trapped by the struggle of discerning between good and evil.     

北京市流动儿童自尊的发展特点及其与学业行为、师生关系的相关研究

以北京市1018名流动儿童和319名城市儿童为被试,用问卷法,考察北京市流动儿童自尊的发展特点,并探讨学业行为、师生关系对流动儿童自尊的影响.结果表明:(1)流动儿童的自尊发展水平存在显著的年级差异;(2)流动儿童的自尊发展水平显著低于城市儿童,两者在高分组(＞41)和低分组(＜28)所占比例分别为39.8%、60.2%和92.7%、7.3%,差异显著;(3)流动儿童的自尊发展水平存在显著的校际差异,混合公立学校流动儿童的自尊发展水平显著高于打工子弟学校的流动儿童;(4)流动儿童的自尊与学业行为、师生关系的各维度均有显著相关,学业行为中的学习效能感、学习自信心和师生关系中的低冲突性、支持性、关系满意度可以显著预测流动儿童的自尊发展水平.     

儒家传统荣辱观及其当代价值

荣辱观是一个人、一个民族、一个社会对于光荣与耻辱及其社会价值的根本看法和基本观点。光荣通常用以指称有益的、值得褒奖的人和事,耻辱通常用以指称有害的、需要贬斥的人和事。因此,荣辱观实质上也是一种道德评价的价值标准:光荣标示肯定的道德评价,即被指认为对于个人、民族、社会具有正价值;耻辱标示否定的道德评价,即被指认为对于个人、民族、社会具有负价值。恩格斯指出:“每个社会集团都有它自己的荣辱观。”[1]在存在利益差别和对立的社会中,这是完全符合事实的。荣辱观作为一种价值标准,归根到底总是以一定的社会利益为基础和出发…     

良心和启蒙:真善判断权问题

There were two prevailing sentiments in Europe after the Reformation: One opposing papal authority and one advocating individual freedom. This paper analyzes these two sentiments and finds that the concept of conscience is crucial in understanding them. The issue of conscience is about judging truth and good, and in initiating the Reformation, Martin Luther heavily appealed to his conscience while countering Catholic attacks. With the wide dispersal of the Reformation, Luther’s notion of conscience was well received among his supporters throughout Europe. Descartes later transformed Luther’s conscience into an epistemological being (the cogito), and argued that its existence was the only valid thing that survived his thorough skepticism — and as such is the foundation of human knowledge. Rousseau continued this line of thinking, which we call subjectivism, and re-employed the term conscience as a replacement for cogito, holding that conscience is the final authority in judging good and bad; that, as the starting point of human existence, it cannot be withheld from any human being; and that it therefore constitutes an inalienable human right. This paper argues that the Enlightenment was a subjectivist movement propelled by this conscience-cogito-conscience conceptualization, and that it sought to enlighten this inalienable conscience. __________ Translated from Qiushi xuekan 求是学刊 (Seeking Truth), 2008, (1): 47–54
