"顺天应人"的生态自然观与中国古典建筑

“顺天应人”是中国古代生态自然观的主要内容,一方面指人应该顺应自然规律,另一方面指人应该发挥主观能动性,改造自然环境,使之适应人的生存和生活。“顺天应人”的生态自然观对中国古典建筑观念产生了重要的影响,主要体现在“虽由人作、宛自天开”的建筑观和“因地制宜、因势利导”的建筑观方面。无论是顺天还是应人,目的都是使人与自然和谐共处、相得益彰,这对于现代生态伦理学和现代生态建筑学都是具有启发意义的。     

Encapsulated social perception of emotional expressions

In this paper I argue that the detection of emotional expressions is, in its early stages, informationally encapsulated. I clarify and defend such a view via the appeal to data from social perception on the visual processing of faces, bodies, facial and bodily expressions. Encapsulated social perception might exist alongside processes that are cognitively penetrated, and that have to do with recognition and categorization, and play a central evolutionary function in preparing early and rapid responses to the emotional stimuli.     

Item Response Theory with Estimation of the Latent Population Distribution Using Spline-Based Densities

The purpose of this paper is to introduce a new method for fitting item response theory models with the latent population distribution estimated from the data using splines. A spline-based density estimation system provides a flexible alternative to existing procedures that use a normal distribution, or a different functional form, for the population distribution. A simulation study shows that the new procedure is feasible in practice, and that when the latent distribution is not well approximated as normal, two-parameter logistic (2PL) item parameter estimates and expected a posteriori scores (EAPs) can be improved over what they would be with the normal model. An example with real data compares the new method and the extant empirical histogram approach.     

智力分布纵论

智力分布本是心理测量的一项重要内容,但众多心理测量教材往往对此论述不足。因此,本文详述有关智力分布的4个论题:(1)正确理解智商组别的组距和组限的表述;(2)4种智力中等标准之比较;(3)3种智力超常标准之比较;(4)如何计算智力分布类别的理论百分比。     

隐喻在文章语境中的理解--概念隐喻理论探讨

概念隐喻理论认为,语言系统中存在着广泛的隐喻一致性,人们对于隐喻的理解是通过将其匹配到基本的概念隐喻来进行的。但有研究者指出,除了一些新颖的隐喻,惯用隐喻的理解并不需要概念匹配。本研究认为,概念隐喻已经储存在长时记忆中,在文章语境中,无论惯用隐喻还是新颖隐喻的理解都可能产生概念匹配。三个实验支持了这一假设。实验一通过目标句的阅读反应时探讨不同文章版本下目标句的理解情况;实验二和实验三从事后与即时两方面对各种文章版本下的概念匹配情况进行比较。研究结果支持了概念隐喻理论。     

从医师的视角浅析医疗差错的辩证观

医疗差错是影响医疗安全的最重要因素。有效预防和正确处理医疗差错,需要以科学辩证的认识为前提。当前,我国医院管理实践在一定程度上缺乏对医疗差错的辩证认识,导致在处理上存在些许不足。本文从医师的视角,对如何辩证地认识医疗差错进行浅述。指出,医疗差错在相当程度上源于人的出错之天性和医学的复杂性,广泛存在于医疗实践中,发生具有必然性;虽然从表象上看,医疗差错的原因是局部的,但其本质的原因是系统性的;医疗差错是医疗安全系统运行状况的"指示灯",有助于及时地了解安全系统的薄弱环节,为完善和提升系统安全、提高医疗服务水平提供契机。     

文化冲突与价值碰撞:安乐死问题根源探究——兼及反思国内安乐死问题之讨论

20世纪80年代国内学术界及公众对安乐死问题的关注与讨论日渐升温,但总体上对安乐死作为问题的理解和把握仍显不足。安乐死作为一种临终生命处置方式而被争论不止,其缘起于西方文化系统中内在的冲突与价值碰撞,集中表现在:宗教文化、医学职业文化和政治文化领域。这三种文化各自内在的价值冲突与不同文化之间的相互碰撞造就了安乐死问题。     

Dynamics of choice: a tutorial

Choice may be defined as the allocation of behavior among activities. Since all activities take up time, choice is conveniently thought of as the allocation of time among activities, even if activities like pecking are most easily measured by counting. Since dynamics refers to change through time, the dynamics of choice refers to change of allocation through time. In the dynamics of choice, as in other dynamical systems that include feedback, change is away from perturbation and toward a steady state. Steady state or equilibrium is assessed on a longer time scale than change because change is only visible on a smaller time scale. When we compare laws of equilibrium, such as the matching law with laws of dynamics, two possibilities emerge. Self-similarity occurs when the same law can be seen across smaller time scales, with the result that the law at longer time scales may be understood as the expression of its application at smaller time scales. Reduction occurs when the dynamics at a small time scale are incommensurate with the dynamics at longer time scales. Then the process at the longer time scale is reduced to a qualitatively different process at the smaller time scale, as when choice is reduced to switching patterns. When reduction occurs, the dynamics at the longer time scale may be derived from the process at the smaller time scale, but not the other way around. Research at different time scales is facilitated by the molar view of behavior.     

A similarity-based smoothing approach to nondimensional item analysis

The probability that an examinee chooses a particular option within an item is estimated by averaging over the responses to that item of examinees with similar response patterns for the whole test. The approach does not presume any latent variable structure or any dimensionality. But simulated and actual data analyses are presented to show that when the responses are determined by a latent ability variable, this similarity-based smoothing procedure can reveal the dimensionality of ability very satisfactorily.The author wishes to acknowledge the support of the Natural Sciences and Engineering Research Council of Canada through grant A320, and to thank Educational Testing Service for making the data on the Advanced Placement Chemistry Exam available.
