厌而避额外之“利”；喜而趋额外之“害”

趋利避害是生物的本能。《管子·禁藏》云：夫凡人之情, 见利莫能勿就, 见害莫能勿避。“两利相权取其重, 两害相权取其轻”是规范性决策理论的一基本原则。本研究以金钱作为奖赏或惩罚刺激, 检验人们能否理性地遵循“价值最大化”原则。在实验中, 主试以检查硬币生产年代的数目为由, 让被试逐枚地感受两个金钱序列：10元硬币序列(由20枚五角硬币组成)和10.3元硬币序列(由20枚五角硬币和3枚一角硬币组成),随后评定获得(或损失)各金钱序列的高兴(或不高兴)程度, 并从中选择一金钱序列(与硬币等值的金钱)作为其奖赏(或惩罚)。实验为2 (3枚一角硬币在序列首vs. 3枚一角硬币在序列尾)´2(先检查10元硬币序列vs. 先检查10.3元硬币序列)´2(损失vs. 获得)三因素设计, 每种条件随机分配15名商学院学生被试。结果表明, 被试倾向选择获益少(10元)和损失多(-10.3元)的金钱序列; 且获益大(10.3元)时高兴程度小, 损失小(-10元)时不高兴程度大。这一结果意味着：“聊”并不胜于“无”,反而是“无”胜于“聊”。其中, 伴随着违背价值最大化原则所产生的情感亦有悖逻辑。负性情感的引发一般有其“逻辑正确”的原因(如, 无惠而不乐); 而引发本研究负性情感的原因实属“逻辑错误”(如, 惠多而不乐)。这种不曾被定义而类似于“冤”的情感不仅见于个人,也见于民族、国家间的持续交往, 值得进一步研究。     

On the equivalence between elimination-by-aspects and generalised extreme value models of choice behaviour

Elimination-by-aspects and generalised extreme value offer competing paradigms for the representation of a common behaviour, that of individual discrete choice. Observing certain consistencies in their mathematical structure, several eminent authors have commented on the degree of equivalence between the two paradigms. Most contributions to this debate have, however, been less than definitive. More fundamentally, the contributions lack consensus. We advance the debate by establishing formal mathematical conditions under which three-alternative tree models from the two paradigms are exactly equivalent. We then extend our analysis to consider more general models, showing that equivalence can be established for general tree models, but not for cross-nested models.     

VIRTUAL REALITY,ONTOLOGY, AND VALUE

Abstract: This article raises the question of how the ontological status of virtual objects bears on their intrinsic value. If virtual objects are unreal or less real than physical objects, does it mean that they will have less intrinsic value? If they have intrinsic value, what are the explanations for this value, and how do they relate to the ontological status of the virtual objects? First, the article reviews recent work concerning the ontological status of virtual reality and virtual objects. Second, it argues that in some cases the ontological status of virtual objects does undermine the value placed in them, in that the objects can fail to have the properties that ground the value attributions made to them, while in other cases their ontological status is not important. Finally, the article relates the grounding of value attributions to philosophical theories of value, in particular, perfectionism and hedonism.     

Taxicab Correspondence Analysis

Taxicab correspondence analysis is based on the taxicab singular value decomposition of a contingency table, and it shares some similar properties with correspondence analysis. It is more robust than the ordinary correspondence analysis, because it gives uniform weights to all the points. The visual map constructed by taxicab correspondence analysis has a larger sweep and clearer perspective than the map obtained by correspondence analysis. Two examples are provided. This research was financed by the Natural Sciences and Engineering Research Council of Canada. The author thanks Serge Vienneau for his help regarding the graphical displays, and also thanks the editor, associate editor, and two reviewers for their constructive comments.     

关于医学人文教学几个问题的认识

文化素质教育与人文教育有联系,但也有区别;对人文精神的理解,存在东方与西方、传统与现在的差异;人文精神的核心是人是一切的根本,人的生命、思想、理想应当受到关爱和尊重;人文精神或人文主义包括理念层次和实践层次;人文精神是一种普世价值而主要不是意识形态;人文知识不等于人文素养,医学人文教育的目标是提升学生对生命的尊重与关爱;医学人文教育应当渗透到医学专业教育之中。     

医学高新技术在现代医患关系中扮演的角色

医学高新技术在现代医患关系中扮演着重要的角色,然而在缺乏有效的政府监管、医院与医生逐利行为及社会不良导向等因素下,其自身的角色发生了异化。通过对异化现象、产生原因及采取措施等方面的分析,明确其正确的价值取向,以促进医患关系的健康、和谐发展。     

Is that all there is?

I take issue with two suggestions of Joel Feinberg's: first, that it is incoherent to suppose that human life as such is absurd, and, second, that a particular human life may be absurd and yet saved from being tragic by being fulfilled. I also argue that human life as such may well be absurd and I consider various responses to this.     

Development of the Japanese Version of the Achievement Emotions Questionnaire – Elementary School (AEQ-ES-J)1,2

The purpose of this study was to develop and validate a Japanese version of the Achievement Emotions Questionnaire – Elementary School (AEQ-ES), which assesses enjoyment, anxiety, and boredom experienced by elementary school students within the settings of attending class, doing homework, and taking tests. Japanese elementary school students (n = 863 for the first survey; n = 332 for the second survey) participated in the questionnaire survey. The results showed that the psychometric properties of the Japanese AEQ-ES were comparable to those of the original version. Moreover, the results showed that students' achievement emotions were associated with their control and value appraisals, as well as their academic motivation, learning strategies, academic performance, and support from teachers. These results indicated that the Japanese version of the AEQ-ES was a good measure of elementary school students' emotions and supported the propositions of the control–value theory of achievement emotions.     

男性择偶策略改变的前提：自感配偶价值提高

研究分为问卷调查与实验研究两部分。首先,40名女性和33名男性完成有关自感配偶价值评价（SPMV）和择偶偏爱策略的问卷调查,问卷调查结果是实验研究中数据分析的基线。其次,第二部分实验开始后,被试会得到实验者编造的他人潜在择偶对象的积极正面评价,其目的在于提高被试的SPMV。可以假设,男性的SPMV与随意性行为的认同或追求有正相关,男性SPMV的提高将会更加偏爱短期的性策略;女性SPMV与随意性行为不存在相关,女性SPMV的提高不会改变女性的性策略。研究结果显示,SPMV高基线水平的男性更加认可随意性行为,男性SPMV的提高与短期策略选择的增加有关。另外,SPMV提高,而不是一般自尊的提高,与择偶策略的改变具有相关。本研究结果没有证实,与长期稳定的性关系相比,SPMV的基线水平或是提高与女性对随意性行为的认同或追求之间存在相关     

How to turn a hawk into a dove and vice versa: Interactions between emotions and goals in a give-some dilemma game

The present study investigated emotional influences on behavior in a one-shot, simultaneous, give-some dilemma game. In accordance with functional perspectives on the role of discrete emotions, we found fear to reduce, and guilt to increase levels of cooperation. Moreover, we showed individual differences in the effect of induced emotional states. Specifically, results indicated that inducing fear reduced cooperation only for individuals with a pro-social value orientation, and that guilt induction increased cooperation only for individuals with a pro-self value orientation. We also established that both social value orientations could be adequately described in terms of differences in chronically accessible goals (as assessed by value-importance ratings). These results, therefore, seem to support our hypothesis that individual differences in the behavioral consequences of induced emotional states are related to variation in chronic accessibility of general goals associated with a particular emotional state.
