A subjectivist approach to consecutive conflict

An easily applied approach is developed to provide one participant in a sequence of conflicts with an optimal strategy. A goal of this article is to demonstrate that it is mathematically feasible to incorporate a decision maker's subjective distributions over the effects his actions will have on the outcomes of future conflicts. Unlike many other approaches, the model of this article does not restrict the beliefs that the participant is allowed to express. The participant, not the decision theorist, decides on what is relevent. Model assumptions required for updating rules, such as Bayesian updating, are not required unless they really are appropriate for the situation.Thanks are due to J. B. Kadane for suggesting the problem and for many helpful discussions.     

法律保护公民性权利的应然分析

在人类社会进入到以张扬个人权利为核心的现代社会,性权利沦为性秩序的牺牲品的年代应渐成历史;揭开婚姻囚禁性权利的面纱也并非难事。从性秩序走向性权利的过程对法律的诉求自然会越来越高。揭开公民性权利长期以来被遮蔽的面纱,尊重并切实保护公民的性权利,使其从应然走向实然,从伦理走向法律,在法律的自由空间最大限度地实现自身的彻底解放应是法律不得不挑起的重担。     

从和谐管理理论到和谐社会的机制分析

面对多元化的社会冲突与构建和谐社会的大背景,在回顾和谐管理理论的基础上,构造了一个在复杂多变环境下基于智能体的心理偏好和行为模式的和谐机制,指出智能体心理偏好和行为模式变化有一定的滞后性,和谐管理就是要改造和实现一定的心理偏好和行为模式;构建社会主义和谐社会,应该实现社会智能体“以人为本”心理偏好和行为模式。     

信息不对称与人的经济行为

信息不对称及其经济效应是信息经济学研究的中心问题,本文依据信息经济学和行为科学理论,从现实经济生活出发,系统地阐述了信息不对称的内涵,论证了信息不对称的必然性,探讨了信息不对称条件下交易双方的经济行为,提出了信息不对称条件下卖方(或代理方)违规败德行为的函数式,最后讨论了信息不对称造成的经济后果,提出了解决这一问题的思路。     

消费活动伦理意蕴探析

消费不仅是一种经济行为,它还具有伦理意义。消费活动与社会道德状况密切相关。消费心理总是一定的人生观、价值观和幸福观的体现,反映一个阶级或时代的道德风貌;消费行为总是对社会产生一定的道德后果;消费方式总是影响着一定阶级或时代的道德风尚。因而,我们应提高精神文化消费,养成科学、文明、健康的合理消费方式和艰苦创业的良好精神风貌,不断弘扬倡俭崇实的良好社会风尚。     

产品设计的行为导向模式研究

长久以来,用器物文化规范社会秩序,引导人们行为都是社会发展的主题。但随着工业化大生产和以追求销售为目的的商业设计的出现,产品设计的行为导向问题受到了忽略。该文从研究日常行为,引导积极的行为,克服不良行为,创造新行为,形成设计文化,实现行为导向功能的可持续发展等方面对生活中常见的一些产品设计进行了实例分析。以探究如何设计产品来引导积极的行为、情感效应和避免消极的负面行为的发生。     

Pathways between education and health: a causal modelling approach

Summary.  The association of poor education and poor health has been consistently observed in many studies and in various countries. Thus far, studies examining the mechanisms underlying this association have looked at only a limited set of potential pathways. This study simultaneously examines six distinctive pathways, which have been hypothesized to link education and health and found support from previous studies. A causal analysis of education and health was performed using structural equation models. Data were used from six phases of the National Child Development Study, which is based on following up an initial sample of 17416 children who were born in 1958. The association between education and health appears to be explained by a combination of mechanisms: adolescent health and adult health behaviours for men and women, adult social class among men and parental social class among women. We conclude that improvements in population educational attainment may not automatically lead to improvements in population health, and that health policies for improving health and reducing health inequalities need to target specific causal pathways.
