There is an exponential speed-up in the number of lines of the quantified propositional sequent calculus over Substitution
Frege Systems, if one considers proofs as trees. Whether this is true also for the number of symbols, is still an open problem.

The important role of hope in the author's thinking is acknowledged. While natural theology is important in its proper place, Christian theology centers on the God and Father of our Lord Jesus Christ. Its discourse will need to avail itself of the power of symbol. 相似文献

The brain and immune system form a bidirectional communication network in which the immune system operates as a sense organ to provide the brain with information about infection and injury, thereby allowing the brain to coordinate a defense. Activated immune cells release proteins called cytokines, which signal the brain by both blood and neural routes. Information that reaches the brain across this sensory channel produces large changes in neural activity, behavior, mood, and cognitive functioning. Appreciation of the functioning of this network may illuminate poorly understood aspects of stress, depression, and intraindividual variability in behavior, mood, and cognition. 相似文献

The REMBRANDT system for multicriteria decision analysis consists of both the multiplicative variant of the AHP (which employs a method of pairwise comparative judgements by a decision maker to arrive at final impact scores for the alternatives under consideration) and SMART, the simple multiattribute rating technique (which utilizes direct rating of alternatives to achieve final impact scores). This paper examines the effect of imprecision or uncertainty in the decision maker's pairwise judgements or ratings of alternatives by expressing each pairwise judgement or rating as a probability distribution, and the structure of REMBRANDT's component models is exploited to derive interval judgements or interval ratings of the alternatives’ final impact scores. These interval judgements or interval ratings can be used to determine the probability of rank reversal amongst alternatives, i.e. to assess the stability of the final impact score vector. © 1998 John Wiley & Sons, Ltd. 相似文献

Late in the 2016 U.S. Presidential primary, Donald Trump attacked Hillary Clinton for playing the “woman’s card.” Theories of system justification suggest that attitudes about gender, particularly endorsement of hostile and benevolent sexism, likely shaped reactions to this campaign attack. Using a set of two studies, we find that hostile sexists exposed to the attack showed increased support for Trump and decreased support for Clinton. Benevolent sexists, however, reacted to Trump’s statements with increased support for Clinton, consistent with benevolent sexism’s focus on protecting women (Study 1). We further found that the woman card attack produced distinct emotional reactions among those with low and high levels of hostile and benevolent sexism. The attack also increased political participation among hostile sexists (Study 2). Our results offer new insights into the role of sexism in the 2016 presidential contest and further the discipline’s understanding of the gendered dimension of negative campaigning. 相似文献

A widespread view in the philosophy of mind and action holds that intentions are propositional attitudes. Call this view ‘Propositionalism about Intention’. The key alternative holds that intentions have acts, or do-ables, as their contents. Propositionalism is typically accepted by default, rather than argued for in any detail. By appealing to a key metaphysical constraint on any account of intention, I argue that on the contrary, it is the Do-ables View which deserves the status of the default position, and Propositionalism which bears the burden of proof. I go on to show that this burden has not been met in the literature. 相似文献

The current study aimed to extend the understanding of the early development of spontaneous facial reactions toward observed facial expressions. Forty-six 9- to 10-month-old infants observed video clips of dynamic human facial expressions that were artificially created with morphing technology. The infants’ facial responses were recorded, and the movements of the facial action unit 12 (e.g., lip-corner raising, associated with happiness) and facial action unit 4 (e.g., brow-lowering, associated with anger) were visually evaluated by multiple naïve raters. Results showed that (1) infants make congruent, observable facial responses to facial expressions, and (2) these specific facial responses are enhanced during repeated observation of the same emotional expressions. These results suggest the presence of observable congruent facial responses in the first year of life, and that they appear to be influenced by contextual information, such as the repetition of presentation of the target emotional expressions. 相似文献

大脑中线电极诱发的μ抑制波(包括α和β频段)是人类镜像系统活动的电生理指标。尽管音乐情绪表现被认为是通过模仿个体的心理状态来实现的, 但是尚未有研究探讨人类镜像系统与音乐情绪加工的关系。本研究通过EEG技术, 采用跨通道情绪启动范式, 探究人类镜像系统是否参与和弦情绪的自动加工。愉悦或不愉悦的和弦启动情绪一致与不一致的目标面孔。行为结果显示, 被试对情绪一致面孔的反应显著快于情绪不一致面孔的反应。EEG结果显示, 在听觉刺激出现后的500~650 ms之间, 与情绪一致条件相比, 情绪不一致条件诱发了β频段的去同步化。在听觉刺激出现后的300~450 ms, 无论是情绪一致, 还是不一致条件, 都诱发了α频段的去同步化。源分析结果显示, μ抑制波主要出现在人类镜像系统的相关脑区。这些结果表明, 音乐情绪的自动加工与人类镜像系统的活动密切相关。 相似文献
