基于元认知的认知学习对动态能力影响的实证研究

通过实证研究勾勒出符合动态特征的元认知理论框架,提出构成元认知的6个要素,分别归为元认知策略、元认知调控和元认知知识三个维度.并借助结构方程模型重点分析了元认知、认知学习和动态能力的相关性,以及基于元认知的认知学习对动态能力演化的影响.     

LÉVY HIERARCHY IN WEAK SET THEORIES

We investigate the interactions of formula complexity in weak set theories with the axioms available there. In particular, we show that swapping bounded and unbounded quantification preserves formula complexity in presence of the axiom of foundation weakened to an arbitrary set base, while it does not if the axiom of foundation is further weakened to a proper class base. More attention is being paid to the necessary axioms employed in the positive results, than to the combinatorial strength of the positive results themselves.     

永党元贤《鼓山志》及其文献价值

元贤是清初具有强烈民族意识和气节的禅僧,他的<鼓山志>在清初编纂刊印以后,一直没有广为流通.清修<四库全书>仅有存目,未收全书,国家图书馆等处所收藏的此书均为残本.本文依据的<鼓山志>现藏于世界宗教研究所,为品相极佳的足本,最早被清初藏书家汪宪收藏,乾隆修<四库全书>时呈于朝廷,又辗转藏于八千卷楼、江苏省图书馆,后流传至民间.该书具有重要的版本价值,内中题记、钤印等亦极为珍贵.本文还考察了历代编修的鼓山寺志的内容和存佚情况,对元贤的流传和撰述时间进行了考证,并在标点校勘该书的基础上,与黄任的<鼓山志>的内容加以比较,指出元贤所编的<鼓山志>从内容、特色以及版本上都具有极为重要的文献价值.     

Differential roles for hippocampal areas CA1 and CA3 in the contextual encoding and retrieval of extinguished fear

Recent studies demonstrate that context-specific memory retrieval after extinction requires the hippocampus. However, the contribution of hippocampal subfields to the context-dependent expression of extinction is not known. In the present experiments, we examined the roles of areas CA1 and CA3 of the dorsal hippocampus in the context specificity of extinction. After pairing an auditory conditional stimulus (CS) with an aversive footshock (unconditional stimulus or US), rats received extinction sessions in which the CS was presented without the US. In Experiment 1, pretraining neurotoxic lesions in either CA1 or CA3 eliminated the context dependence of extinguished fear. In Experiment 2, lesions of CA1 or CA3 were made after extinction training. In this case, only CA1 lesions impaired the context dependence of extinction. Collectively, these results reveal that both hippocampal areas CA1 and CA3 contribute to the acquisition of context-dependent extinction, but that only area CA1 is required for contextual memory retrieval.     

Philosophy, the “unknown knowns,” and the public use of reason

There are not only true or false solutions, there are also false questions. The task of philosophy is not to provide answers or solutions, but to submit to critical analysis the questions themselves, to make us see how the very way we perceive a problem is an obstacle to its solution. This holds especially for today’s public debates on ecological threats, on lack of faith, on democracy and the “war on terror”, in which the “unknown knowns”, the silent presuppositions we are not aware of, determine our acts.     

医疗价格过度增长的管制原因分析

医疗服务的准公共产品特征说明医疗价格问题不能完全由市场来解决,政府必须对医疗价格进行管制。造成医疗价格高昂的原因是多样的和复杂的,基于对医疗价格的政府管制现状分析,认为对医疗价格的管制不善,是导致中国高昂医疗价格的原因之一,并且提出了对医疗价格进行管制的制度框架。     

从新行为主义到社会建构主义:班杜拉研究范式的转变

班杜拉的社会认知理论是一种关于人类学习和发展的社会建构主义的观点,标志着其研究范式的转变:从新行为主义到社会建构主义。本文根据社会建构主义的五条基本原则,对他的社会认知理论进行了分析,分析的结果表明其主要的理论原则、论点,以及心理学构想不仅与社会建构主义思想一致,还与关于人类活动的行为主义的观点相对立。因此,对班杜拉研究成果的准确解释于教学、科研和学术成就都具有决定性的意义。
