李丽云因为丈夫拒签手术同意书而造成“一尸两命”的事件,“拒签”事件击中了医疗法规知情同意权在医疗实施过程中的软肋。如何保护病人的生命权、被救助权和手术权,如何让医院救死扶伤而没有后顾之忧,建议政府部门应该建立相应的“国家担保”制度,使病人得到最为及时有效的抢救和治疗。以免类似的悲剧再次发生。 相似文献

Over the history of the study of visual perception there has been great success at discovering countless visual illusions. There has been less success in organizing the overwhelming variety of illusions into empirical generalizations (much less explaining them all via a unifying theory). Here, this article shows that it is possible to systematically organize more than 50 kinds of illusion into a 7 × 4 matrix of 28 classes. In particular, this article demonstrates that (1) smaller sizes, (2) slower speeds, (3) greater luminance contrast, (4) farther distance, (5) lower eccentricity, (6) greater proximity to the vanishing point, and (7) greater proximity to the focus of expansion all tend to have similar perceptual effects, namely, to (A) increase perceived size, (B) increase perceived speed, (C) decrease perceived luminance contrast, and (D) decrease perceived distance. The detection of these empirical regularities was motivated by a hypothesis, called "perceiving the present," that the visual system possesses mechanisms for compensating neural delay during forward motion. This article shows how this hypothesis predicts the empirical regularity. 相似文献

中国背景下员工沉默的测量以及信任对其的影响 总被引:10,自引:0,他引:10
应用自行编制的员工沉默行为调查问卷,通过对928名被试的调查,对中国背景下员工沉默行为的结构维度进行了探讨。探索性因素分析结果表明,员工沉默由三个因素构成。三因素结构的结果在验证性因素分析中得到了证实。由此得到结论,员工沉默有三维结构:默许沉默、漠视沉默和防御沉默。以员工沉默的三个维度为因变量,以员工对上级和组织的信任为自变量进行回归分析,结果表明,员工对上级信任对员工沉默三个维度都有负面影响,而员工对组织信任对默许沉默和漠视沉默有负向影响,对防御沉默的影响并不显著 相似文献

This article takes on a perhaps impossible task: not only to reconstruct the core argument of Arthur Peacocke's program in science and religion but also to evaluate it in two major areas where it would seem to be vulnerable, namely, more recent developments in systems biology and the philosophy of mind. If his theory of hierarchies is to be successful, it must stand up to developments in these two areas and then be able to apply the results in a productive way to Christian theological reflection. Peacocke recognized that one's model of the mind‐body relation is crucial for one's position on the God‐world relation and divine action. Of the three models that he constructed, it turns out that only the third can serve as a viable model for theology if it is to be more than purely deistic or metaphorical. 相似文献

The late nineteenth century was not only a time in which religious faith was questioned in light of increasing claims of natural science. It is more accurate to see the familiar Victorian crisis of faith as but one aspect of a larger historical phenomenon, one in which the methods of both religion and science came under scrutiny. Among several examinations of the status of scientific knowledge in the waning decades of the century, the treatment of the subject by the German theologian Wilhelm Herrmann and philosopher Hans Vaihinger rejected its objective nature and denied that either scientists or theologians had access to the truth of nature. Although this stance regarding the nature of science, religion, and their relationship was limited to intellectuals in German society at the time, it foreshadowed developments in our own day in which the traditional search for truth has been problematized. 相似文献

In Islam, the acquisition of knowledge is a form of worship. But human achievement must be exercised in conformity with God's will. Warnings against feelings of superiority often are coupled with the command to remain within the confines of God's laws and limits. Because of the fear of arrogance and disregard of the balance created by God, any new knowledge or discovery must be applied with careful consideration to maintaining balance in the creation. Knowledge must be applied to ascertain equity and justice for all of humanity. Research in Islam must be linked to the broad ethical base set forth in the Qur'an and the Sunnah. Whether embryonic stem cell research or cloning is ethically acceptable in Islam depends on the benefits derived from such applications. What is most important for the scholars is to adhere to the concepts of compassion, mercy, and benefit to everyone. 相似文献

The winner's curse phenomenon refers to the fact that the winner in a common value auction, in order to actually win the auction, is likely to have overestimated the item's value and consequently is likely to gain less than expected and may even lose (i.e., it is said to be “cursed”). Past research, using the “Acquiring a company” task has shown that people do not overcome this bias even after they receive extensive feedback. We suggest that the persistence of the winner's curse is due to a combination of two factors: variability in the environment that leads to ambiguous feedback (i.e., choices and outcomes are only partially correlated) and the tendency of decision makers to learn adaptively. We show in an experiment that by reducing the variance in the feedback, performance can be significantly improved. Copyright © 2007 John Wiley & Sons, Ltd. 相似文献

运用情景模拟和角色扮演的方法,研究大学生对网瘾和作弊的责任归因结构及其应对策略。对416名被试的研究结果显示:(1)责任归因的心理结构是一个“责任推断→责任情感→责任行为”的一元结构模式。(2)我国大学生的责任推断过程与维纳的经典理论基本一致,但在行为应对策略上存在一定的文化差异。(3)大学生对网瘾和作弊的责任推断倾向明显并与情感体验基本保持一致,但与行为应对策略存在一定的冲突。(4)大学生在网瘾和作弊的责任推断、情感体验以及应对策略上存在一定差异。 相似文献

在多重系统理论研究基础上,运用即时反馈训练范式,以大学生为被试,考查相关维度数量对基于规则和信息整合两种结构的类别学习的影响.结果表明:(1)相关维度数量是影响类别学习的重要因素,基于规则单维度结构的学习显著优于信息整合结构和基于规则双维度结构的学习,基于规则双维度结构的学习与信息整合结构的学习没有显著差异.(2)反应策略受到规则复杂性的影响,当类别结构中隐含的规则比较简单时,学习者使用规则策略;当类别结构中隐含的规则比较复杂时,学习者难以掌握规则,就会使用相似性策略.研究结果支持"难度观",而不支持多重系统理论. 相似文献
