李哲 《管子学刊》2009,(4):10-13
《管子》在强调"以法治国"的同时,又推崇"守国之度,在饰四维"的德教思想,而且二者相互为用,共同服务于以君主为核心的国家统治,表现出了齐法家学派独特的治国经民理论。  相似文献

记叙文阅读中时间心理表征的建构:动态观还是静态观   总被引:1,自引:0,他引:1  
探讨读者在文本阅读中如何通过一系列展开事件的描述建构心理表征。实验一探讨在中间事件持续时间长/短条件下对首尾呼应句阅读时间和对探测词反应时间的影响;结果表明,读者对第一事件信息的获得受中间事件的持续时间长短的影响。实验二探讨当信息储存在长时工作记忆中时能否得出与实验一相一致的结果。结果发现,读者对第一事件信息的获得不受中间事件的持续时间长短的影响。实验三考察当用明确的时间副词来表明持续时间的长短时,连续性的事件是否还存在着时间距离效应。实验结果与实验二的相一致。整个研究结果表明,时间心理表征的建构是动态观还是静态观,主要取决于是否存在时间距离效应。  相似文献

研究从先验概率、概率表征、推理任务等方面探讨了经典贝叶斯推理研究中存在的不足,试图在"知识和试题双重模型"框架下,探索现实和标准贝叶斯试题的形式结构的同质性,结果表明:1)自然频次表征比百分比表征的贝叶斯推算题正确率高,这是因为试题的形式结构不同,与概率表征无关;2)贝叶斯判断题与贝叶斯推算题的试题形式结构存在显著差异;3)贝叶斯推算题中,概率词表征与其它两种表征的试题形式结构存在显著差异,其实质是贝叶斯判断。  相似文献

This study examined HIV/AIDS‐related stigma among Chinese service providers by comparing their personal attitudes toward people living with HIV/AIDS with their perception of social norms related to people living with HIV/AIDS. We randomly selected three provincial hospitals, four city/prefecture hospitals, 10 county hospitals, 18 township health clinics, and 54 village clinics from Yunnan, China. Doctors and nurses were randomly sampled proportionally to the doctor–nurse ratio of each hospital or clinic. Lab technicians were over‐sampled in order to include an adequate representation in the analysis. A total of 1,101 service providers participated in a voluntary, anonymous survey where demographic characteristics, individual attitude and perceived social norms toward people living with HIV/AIDS, discrimination intent at work, general prejudicial attitude and knowledge on HIV/AIDS were measured. A majority of the sample demonstrated a similarity between their personal views and what they thought most people in society believe. Multiple logistic regressions revealed that participants who were younger or reported personal contact with people living with HIV/AIDS were significantly more likely to report personal attitudes toward the population that were more liberal than their perceived social norms. Holding a more liberal personal attitude toward people living with HIV/AIDS than perceived social norms was significantly and negatively related to the level of discrimination intent at work, perceived discrimination at interpersonal level and the level of general prejudicial attitude toward people living with HIV/AIDS. Results underscored the importance of understanding social norms and personal attitudes in studying HIV‐related stigma and called for the incorporation of existing human capital into future HIV stigma reduction programs.  相似文献

Weber & Hsee (1998) proposed the “cushion effect” as an explanation of the higher risk taking observed in some East Asian samples, relative to Western samples. Yates, Lee, & Shinotsuka (1992 ) proposed that the overconfidence observed in most Asian countries, relative to Western countries, reflects differences in the number of arguments typically recruited in those countries. This study examined the 2 seemingly separated domains of research: risk taking and overconfidence. It compared individual and collective (both family and group) decisions among Chinese in Singapore. This permitted tests of both the cushion and the argument recruitment hypotheses. The overall results obtained no support for the cushion effect and partial support for the argument recruitment hypotheses.  相似文献

Cluster Analysis for Cognitive Diagnosis: Theory and Applications   总被引:3,自引:0,他引:3  
Latent class models for cognitive diagnosis often begin with specification of a matrix that indicates which attributes or skills are needed for each item. Then by imposing restrictions that take this into account, along with a theory governing how subjects interact with items, parametric formulations of item response functions are derived and fitted. Cluster analysis provides an alternative approach that does not require specifying an item response model, but does require an item-by-attribute matrix. After summarizing the data with a particular vector of sum-scores, K-means cluster analysis or hierarchical agglomerative cluster analysis can be applied with the purpose of clustering subjects who possess the same skills. Asymptotic classification accuracy results are given, along with simulations comparing effects of test length and method of clustering. An application to a language examination is provided to illustrate how the methods can be implemented in practice.  相似文献

This study examines the relation between maternal physical discipline and victimization by peers, as moderated by child aggression. The sample consisted of 211 Hong Kong Chinese children (98 boys, 113 girls; average age of 11.9). Physical discipline was assessed with a questionnaire completed by mothers, and victimization by peers and aggression were measured using a peer nomination inventory. Latent variable models revealed a moderately strong link between children’s experiences with maternal physical discipline and peer victimization, but this effect held only for children who were also high on aggression. These results highlight the interplay between harsh home environments and child aggression and their contributions to the child’s adjustment in the peer group.  相似文献

This fMRI study examined the neural correlates of the observed improvement in advantageous risk-taking behavior, as measured by the number of adjusted pumps in the Balloon Analogue Risk Task (BART), following a 60-day course of a Traditional Chinese Medicine (TCM) recipe, specifically designed to regulate impulsiveness in order to modulate risk-taking behavior. The 14 participants recruited for this study were randomly assigned to the experimental and control groups and the TCM recipe (Panax, 520 mg; Astragalus membranaceous Bunge, 520 mg; Masnetitum, 840 mg; Ostrea gigas Thumb, 470 mg; Thinleaf Milkwort Root Radix Polygalae, 450 mg; and Os Draconis, 470 mg) was administered, as a diet supplement, to the seven participants in the experimental group. The neural activity of the two groups was monitored by a 3T MRI scanner, before and after the 60-day treatment. Associated with the improved advantageous risk-taking behavior seen in the experimental group, significantly stronger blood oxygenation level dependent (BOLD) responses were observed in the bilateral dorsolateral prefrontal cortex (DLPFC), left putamen, left thalamus, right insula, and right anterior cingulate cortex (ACC), regions which have previously been reported as being involved in risk-taking decision making. The effect of the TCM in improving advantageous risk-taking decision making appears to have been related to the enhanced efficiency of the cognitive affective system, the PFC–ACC–insula–striatum network, which functions to inhibit impulsiveness, to sensitize reward-related information, and to allow the opportunity, during risk estimation, to evaluate potential gains and losses. The findings of this study suggest that interventions acting on factors modulating risk-taking decision making could have a beneficial effect in terms of optimizing risk-taking behavior.  相似文献

世界知识在句子理解中的整合时程   总被引:1,自引:0,他引:1  
Hagoort等(2004)应用背离范式发现世界知识和单词意义在句末的整合是同时进行的。本研究将背离信息提前到句首短语中,旨在探讨世界知识在句子阅读过程中被整合的时程特征。实验采用四词句子为材料,其中第二个词(目标词)含有单词意义或世界知识背离信息,记录并比较被试在阅读后三个词时诱发的脑电变化。结果发现:与正确句子比较,无论是单词意义背离还是世界知识背离,背离目标词均引发出经典的N400,二者在峰值时间和始潜时上无显著差异,但世界知识背离信息诱发的N400波幅值相对较小。句中的后继单词不再诱发类似的N400;但到句子结尾,两类含有背离信息句子的句末正常单词又诱发出类似N400的一个负波。结果提示,在句子理解过程中,世界知识的整合与单词意义的整合相似,可能是随着句子理解过程即时进行的,整合的结果不影响后继信息的加工;但到了句末,读者在对整个句子内容作真实性判断时会对先前进行过的整合再进行考察。  相似文献
