现代慈善事业及其在中国的发展 总被引:36,自引:2,他引:34
慈善事业是建立在社会捐献基础之上的民营社会性救助事业,是一种混合型分配方式。慈善事业以社会成员的善爱之心为道德基础,以贫富差别的存在为社会基础,以社会捐献为经济基础,以民营机构为组织基础,以捐献者的意愿为实施基础,以社会成员的普遍参与为发展基础。在阐述慈善事业的组织与运行机制的条件下,讨论了处理好慈善事业发展中的若干关系问题。提出中国不仅需要发展慈善事业,而且具备发展慈善事业的基本条件,目前的关键在于对慈善事业进行合理定位并进一步完善慈善法制等 相似文献

大学生成就需要、自尊水平与应对方式的相关研究 总被引:8,自引:0,他引:8
使用测量方法对312名大学生的成就需要、自尊水平和应对方式之间的关系进行了研究。结果发现,大学生总体上趋向于选择问题解决、求助等积极的应对方式而不是自责、退避等消极的应对方式。自尊水平的高低对每项应对方式的选择都有显著影响,而成就需要的高低只对问题解决应对方式有显著影响。除了求助方式外,其他应对方式均不存在性别差异。女大学生比男大学生更倾向于选择求助方式。 相似文献

已知创伤后应激障碍(posttraumatic stress disorder, PTSD)患者表现出HPA轴(hypothalamic-pituitary- adrenocortical axis)功能异常, 而皮质醇是反映PTSD患者HPA轴功能的重要生物标记。近期的研究结果提示, PTSD患者的皮质醇水平变化可能有明显的时间序列特征, 即应激事件发生后先升高, 后下降至正常水平之下。这一特征受到生物标记的时间特性, 患者病程, 应激源类型和强度, 伴生疾病等因素的干扰和掩蔽。未来研究应进一步采用长期追踪设计, 控制干扰因素的影响, 结合急性应激和慢性应激生物标记来综合验证PTSD患者皮质醇水平变化的时间序列特征|并利用该特征预测PTSD的发生、发展, 以便及时进行干预|考虑皮质醇的代谢、拮抗等机制, 结合多种生物标记综合评估、诊断PTSD患者的HPA轴功能活性。 相似文献

When do children acquire an understanding of knowledge and ignorance? We analyzed the early development of children’s spontaneous references to knowing and not knowing and conclude that 2-year-olds talk explicitly and cogently about their own knowledge as well as that of an interlocutor. Two-year-olds also admit their own ignorance. Moreover, consistent with their realization that an informant may know what they do not, 2-year-olds ask many information-seeking questions. Finally, we discuss children’s receptivity and skepticism, especially toward the counterintuitive claims of an adult. We conclude that children’s conception of knowledge and ignorance begins early but undergoes protracted refinement. 相似文献

Speakers respond more slowly when naming pictures presented with taboo (i.e., offensive/embarrassing) than with neutral distractor words in the picture–word interference paradigm. Over four experiments, we attempted to localize the processing stage at which this effect occurs during word production and determine whether it reflects the socially offensive/embarrassing nature of the stimuli. Experiment 1 demonstrated taboo interference at early stimulus onset asynchronies of ?150?ms and 0?ms although not at 150?ms. In Experiment 2, taboo distractors sharing initial phonemes with target picture names eliminated the interference effect. Using additive factors logic, Experiment 3 demonstrated that taboo interference and phonological facilitation effects do not interact, indicating that the two effects originate at different processing levels within the speech production system. In Experiment 4, interference was observed for masked taboo distractors, including those sharing initial phonemes with the target picture names, indicating that the effect cannot be attributed to a processing level involving responses in an output buffer. In two of the four experiments, the magnitude of the interference effect correlated significantly with arousal ratings of the taboo words. However, no significant correlations were found for either offensiveness or valence ratings. These findings are consistent with a locus for the taboo interference effect prior to the processing stage responsible for word form encoding. We propose a pre-lexical account in which taboo distractors capture attention at the expense of target picture processing due to their high arousal levels. 相似文献

The present study captures the dynamics of neural processing across positively contingent, negatively contingent, and noncontingent relations. In the setting of a hypothetical chat room conversation, participants rated the contingency of emotional response between two individuals. Event-related potentials (ERPs) were time-locked to the onset of each emotional event. Although each event alone was ambiguous regarding contingency, its neural response was characteristic of the overall contingent relation and the subsequent contingency rating. Very early displays of contingency modified the ERP anterior N1 (AN1) component amplitude. In contrast, the ERP selection negativity (SN) component amplitude seemed to be more sensitive to display properties than contingency. Our results point to the recruitment of early attentional processes for contingency judgement and highlight the efficiency of statistical information processing. 相似文献
