佛教与传统法律的关系在学界一直受到关注,从宏观到微观的专题研究也取得了越来越丰富的成果。这些成果对二者的关系从静态描述到动态发展阐述,从单向性影响到双向性互动,从大传统到小传统,从历史现象到现实意义,各个领域都有了一定的积累。在进一步的研究中,规范分析方法的运用、民间文本的重视和司法领域的关注,是取得新突破的有效途径。  相似文献

Considerable evidence indicates that the noradrenergic system of the basolateral amygdala (BLA) participates in the consolidation of various types of emotionally arousing memories. We previously reported that administration of an anesthetic-dose of sevoflurane immediately after continuous multiple-trail inhibition avoidance (CMIA) training impaired memory consolidation. This experiment investigated whether posttraining noradrenergic activation of the BLA is sufficient to reverse the memory impairing effect of sevoflurane. Adult male Sprague-Dawley rats received bilateral injections of norepinephrine (NE 0.3, 1.0, or 3.0 μg/0.5 μl) or normal saline (NS 0.5 μl) immediately after training in a CMIA paradigm. Subsequently, the rats were exposed to sevoflurane (2% inspired) or air for 2h. Norepinephrine produced a dose-dependent enhancement of memory consolidation on a 24-h retention test. The highest dose of NE tested (3.0 μg/0.5 μl) blocked sevoflurane-induced impairment of memory consolidation and reversed the inhibitory effect of sevoflurane on activity-regulated cytoskeletal protein (Arc) expression in the hippocampus 2h after training. These findings provide evidence that the mechanism mediating the memory-impairing effect of sevoflurane involves a network interaction between the BLA noradrenergic system and modulation of Arc protein expression in the hippocampus.  相似文献

This study examined the concordance between parental and youth's perceptions regarding open communication in their families and its association with youth's psychosocial adjustment. The relative importance of parental and adolescents' perceptions of open family communication in relation to youth's psychosocial adjustment was also investigated. Participants were 336 parent-youth dyads from inner-city low-income communities in an eastern city in the United States. Both parental and youth's perceptions of open communication in the family were categorized into "high" and "low" groups using a median split in scores. Four parent-youth concordance groups (i.e. high-high, high-low, low-high and low-low) were derived based on the combination of the levels of parental and youth's perceptions. Parental and youth's perceptions about open communication were modestly correlated (r = 0.129, p < 0.05). The level of concordance differed by youth gender with male adolescents and their parents being more likely to perceive lower levels of open communication (i.e. "low-low") than females and their parents (32% versus 19%, p < 0.05). In general, youth demonstrated poorer psychosocial adjustment if they perceived a lower level of open communication between them and their parents, independent of the level of their parents' perceptions (e.g. "high" or "low"). The findings suggest an important role of adolescents' own perceptions of the openness of the family communication in relation to adolescent psychosocial adjustment. Developmentally and gender appropriate intervention programs are needed to improve the openness of parent-adolescent communication, to help both parents and youth to recognize the significant preventive role of open communication in the family, especially, the socioeconomically disadvantaged families.  相似文献

A scandal can evoke public outrage when it is widely publicized and involves an individual who is perceived to have a high level of cultural representativeness. Two experiments showed that when the scandalous target's moral character was highlighted, emotional responses towards the target were least negative when the scandal was widely circulated and when the target was seen as a representative of his culture. These results suggest that when a cultural symbol is implicated in a widely‐circulated scandal, the negative emotions directed towards the scandalous individual can be alleviated when the public remains confident in his or her commitment to morality.  相似文献

In this article, we introduce a software package that applies a corpus-based algorithm to derive semantic representations of words. The algorithm relies on analyses of contextual information extracted from a text corpus—specifically, analyses of word co-occurrences in a large-scale electronic database of text. Here, a target word is represented as the combination of the average of all words preceding the target and all words following it in a text corpus. The semantic representation of the target words can be further processed by a self-organizing map (SOM; Kohonen, Self-organizing maps, 2001), an unsupervised neural network model that provides efficient data extraction and representation. Due to its topography-preserving features, the SOM projects the statistical structure of the context onto a 2-D space, such that words with similar meanings cluster together, forming groups that correspond to lexically meaningful categories. Such a representation system has its applications in a variety of contexts, including computational modeling of language acquisition and processing. In this report, we present specific examples from two languages (English and Chinese) to demonstrate how the method is applied to extract the semantic representations of words.  相似文献

心理契约破坏是个体对组织未能履行其在心理契约中应承担责任的认知评价。文章首先结合以往研究探讨了心理契约破坏与相应结果变量的关系,然后探讨了调节变量的作用,最后从被试群体、研究方法及理论模型的构建上对未来研究进行了展望。  相似文献

部分线索效应指让学习者学习一系列材料,在随后的测试阶段,给学习者提供先前学习的部分材料作为提取线索,让学习者回忆剩余的材料,其回忆成绩反而比没有提取线索时回忆成绩差。该效应的经典理论模型主要有组织干扰假说和提取抑制假说。由于它们有许多分歧之处,最近提出的双机制解释试图将二者融合,显示了诸多优势,但同时也存在一些缺陷。对双机制解释的进一步探索应侧重于确定组织干扰的量、探讨部分线索相对持久抑制作用的过程、界定组织干扰假说和提取抑制假说的关系,此外对部分线索效应在实际学习生活中的检验也很重要。  相似文献

摘要:Dweck研究提出,通过蕴含特定能力观的故事和表扬可以形成儿童相应的能力和目标取向。作者认为,随着儿童能力的自我意识发展,干预会产生不同的效果。本研究以3-9年级885名学生为被试,采取“天分”、“努力”、“无关”三组故事和“聪明”、“努力”、“潜能”、“不表扬”四种评价方式进行能力观干预,将目标得分变化作为干预效果的指标。实验结果显示了年龄和干预方式的交互作用效应,在一定程度上支持了Dweck的研究结论,验证并丰富了作者关于能力观干预发展性效应的设想。  相似文献

采用经济信心问卷、生涯自我效能感量表、总体主观幸福感量表、贝克焦虑和抑郁量表,对237名大学生进行调查,考察大学生经济信心对其心理健康的影响,以及生涯自我效能感在两者之间可能的中介作用。结果表明,经济信心与生涯自我效能感和主观幸福感呈显著的正相关,与抑郁显著负相关,生涯自我效能感与主观幸福感显著正相关,与焦虑、抑郁显著负相关。大学生经济信心对其主观幸福感和抑郁具有显著的预测作用。大学生生涯自我效能感在经济信心与主观幸福感之间起到部分中介作用,其在经济信心和抑郁之间起到完全中介作用。此外,大学生生涯自我效能感传递了经济信心对焦虑的间接影响。  相似文献
