分析在急危重症患者中签署知情不同意的原因,探讨对策.选择我院2010年6月1日~2011年12月30日在ICU抢救已出院归档的急危重症患者家属签署的600份知情同意书中52份不同意的病例进行分析总结.52份病例的知情同意书签字不同意,原因多方面.知情不同意是患者或家属的权力,如何保障更好行使此权利,同时保障其健康是医务人员努力的目标,也需要对出现的问题进一步探讨.  相似文献

Since the 1980s, the so‐called “new six‐theory” (Dissipative structure theory, Synergetics theory, Catastrophe theory, Chaos theory, Fractal theory, and Hypercycle theory), different from the traditional “systems theory,” “information theory,” and “cybernetics theory” (the “old three theory") has been introduced into China. With it, Laszlo's systems philosophy has been given close attention by Chinese scholars. The main elements of this work are analyzed in terms of the publication and research of Laszlo's work on systems philosophy, and more specifically on systems philosophy and the theory of knowledge, systems philosophy and general evolution theory, systems philosophy and the theory of value, and systems philosophy and metaphysics.  相似文献

Although laughter plays an essential part in emotional vocal communication, little is known about the acoustical correlates that encode different emotional dimensions. In this study we examined the acoustical structure of laughter sounds differing along four emotional dimensions: arousal, dominance, sender's valence, and receiver-directed valence. Correlation of 43 acoustic parameters with individual emotional dimensions revealed that each emotional dimension was associated with a number of vocal cues. Common patterns of cues were found with emotional expression in speech, supporting the hypothesis of a common underlying mechanism for the vocal expression of emotions.  相似文献

惯用语是比喻性语言的一种。语义分解性的作用是惯用语理解机制争论的焦点。通过语义启动任务, 探究了汉语动宾结构的惯用语和偏正结构的惯用语的意义理解模式, 揭示语义分解性在短的SOA (300 ms)和长的SOA (800 ms)下的作用。结果发现, 语义分解性独立地影响惯用语的意义激活:当SOA短时, 语义高分解的两类惯用语均表现出显著的字面义激活效应; 当SOA长时, 语义低分解的偏正结构的惯用语的意义激活的正确率优势明显。同时, 两类惯用语的语义分解性不同导致了语义激活启动效应的差异:当SOA短时, 语义低分解的动宾结构的惯用语存在两种意义的激活效应, 语义高分解的动宾结构的惯用语和偏正结构的惯用语存在字面义的激活效应; 当SOA长时, 语义低分解的动宾结构的惯用语存在两种意义的激活效应, 语义高分解的偏正结构的惯用语存在比喻义的激活效应。研究证实语义分解性在惯用语加工早期即发挥作用, 在加工晚期, 语义高分解的动宾结构的惯用语的多种意义同时激活削弱了两种意义的启动优势。整个研究结果支持惯用语理解的混合表征模型和层级显性意义假说。  相似文献

Numerous studies of organized activities have found that participation is associated with a range of positive outcomes; however, findings from recent randomized trials have been more mixed. Understanding youth's psychological experiences of program involvement – their cognitive and emotional reaction to and participation in activities – may be key to understanding the influence of organized activities. Hierarchical linear modeling was used to investigate correlates of youth belonging and cognitive engagement in a sample of 1160 youth in 123 program offerings in 66 sites. Results revealed that intensity (frequency) of exposure positively predicted belonging and cognitive engagement; however, duration was negatively associated with cognitive engagement. The staff practice of providing a welcoming atmosphere predicted belonging; whereas provision of active skill-building predicted cognitive engagement. These relations were found to vary across content type.  相似文献

Brain imaging studies provide strong evidence for the involvement of the human mirror system during the observation of complex movements, depending on the individual's motor expertise. Here, we ask the question whether motor expertise not only affects perception while observing movements, but also benefits perception while solving mental rotation tasks. Specifically, motor expertise should only influence the performance in mental body rotation tasks (MBRT) with left-right judgment, evoking a perspective transformation, whereas motor expertise should not affect the MBRT with same-different judgment, evoking an object-related transformation. Participants with and without motor expertise for rotational movements were tested in these two conditions in the MBRT. Results showed that motor experience selectively affected performance in the MBRT with the left-right judgment, but not with same-different judgment. More precisely, motor expertise only benefited performance when human figures were presented in (for non-experts) unfamiliar, upside-down body orientations.  相似文献

People constantly have to make efficient use of their limited cognitive resources. Recently, T. Mussweiler and K. Epstude (2009) demonstrated that comparative thinking simplifies information processing and increases the efficiency of judgment. However, there are different types of comparative thinking. While comparing 2 entities, people may focus on either similarities or dissimilarities between target and standard. The authors propose that these 2 comparative thinking styles differ in their efficiency. Specifically, the authors hypothesize that comparisons with a focus on similarities lead to more focused information processing and faster judgments than comparisons with a dissimilarity focus. In line with these hypotheses, the authors demonstrate that participants are indeed faster at judging the similarity of 2 stimuli (Study 1) and that they search for less target information in a comparative judgment task (Study 2) if they focus on similarities rather than dissimilarities. Focusing on similarities thus appears to be the more efficient comparative thinking style.  相似文献

Purpose  

This study seeks to examine how perceived organizational instrumentality (the extent to which employees believe that OCB contributes to the functionality and effectiveness of their work unit or organization) and perceived individual instrumentality (the extent to which employees believe that OCB is important to their own interests) relate to employee engagement in OCB and how these perceptions mediate the effects of leadership on OCB.  相似文献

Depressive disorders in childhood are not easily identifiable as distinct nosologic entities because of high comorbidity and developmental specificities of their appearance. Psychopathologic developments show that early recognition and prevention of depressive disturbances have a high relevance in health care. In the following article the authors present the basic principles of the psychoanalytic short-term therapy (PaKT) for the treatment of affective disturbances and emotional symptoms in childhood which they worked out as therapy guidelines in form of a manual.  相似文献
