Any complete preference structure without circuit admits an interval representation

This article proves that all complete preference structures where the strict preference relation (P) has no circuit admit a representation by intervals of the real line; the rule for deciding whether an interval is indifferent or preferred to another is less straightforward than for interval orders: strict preference is indeed compatible with a certain degree of overlapping of intervals, the allowed degree being specified by means of a so-called tolerance function.     

Three pseudo-paradoxes in ‘quantum’ decision theory: Apparent effects of observation on probability and utility

In quantum domains, the measurement (or observation) of one of a pair of complementary variables introduces an unavoidable uncertainty in the value of that variable's complement. Such uncertainties are negligible in Newtonian worlds, where observations can be made without appreciably disturbing the observed system. Hence, one would not expect that an observation of a non-quantum probabilistic outcome could affect a probability distribution over subsequently possible states, in a way that would conflict with classical probability calculations. This paper examines three problems in which observations appear to affect the probabilities and expected utilities of subsequent outcomes, in ways which may appear paradoxical. Deeper analysis of these problems reveals that the anomalies arise, not from paradox, but rather from faulty inferences drawn from the observations themselves. Thus the notion of quantum decision theory is disparaged.     

我国上市公司盈余管理行为的实证分析

我国证券市场存在较为严重的盈余管理现象.针对该现象,本文从盈余管理动机出发,分析我国上市公司盈余管理的行为特征.本文采用管理后盈余分布法,研究了我国上市公司2001年至2003年净资产收益率(ROE)的分布特征,发现我国上市公司仍然存在很强的盈余管理动机,而且我国上市公司盈余管理的行为受到政府监管的影响.最后,本文在实证研究的基础上提出了治理盈余管理的几点建议.     

网络时代农产品质量安全事件风险放大机制研究——基于价值累加理论的扎根分析

随着互联网的飞速发展,农产品质量安全事件借助网络媒体持续关联与聚合、发酵与扩散,极大地影响着公众的情感和态度,易引发集体非理性恐慌,网络时代信息扩散和迭代呈现全新特征和趋势,故加强农产品质量安全事件风险放大机制研究具有重要意义。基于斯梅尔塞的价值累加理论,结合“土坑酸菜”事件,利用Python技术获取媒体原始资料,对资料进行扎根编码分析,构建农产品质量安全事件风险放大机制模型。根据编码结果识别出农产品质量安全事件风险放大六大主范畴,包括结构性诱因、结构性紧张、一般化信念、(有效的)组织动员、社会控制、风险放大,将主范畴内容纳入价值累加理论六大因素中,分析表明农产品质量安全事件风险放大是以突发事件为分界点,分为前期蓄势、中期造势、紧急处理三个阶段,前期蓄势和中期造势阶段通过多轮循环相互反馈影响,最终放大农产品质量安全事件风险。在整个风险扩散过程中,网络是农产品质量安全事件风险的“社会放大站”,其加速了信息传播,强化了公众风险感知。本研究运用价值累加理论、基于宏观和微观整合层面,细化探究了网络时代农产品质量安全事件风险放大的完整过程机制,进一步完善了风险放大SARF研究框架,为相关研究做了有益补充。     

后现代主义教育视野下的师生观

后现代主义(postmodernism)是20世纪后半叶在西方社会流行的一种哲学、文化思潮。它脱胎于信息化后工业社会。后现代教育思想作为整个后现代思潮的一部分,它强调个人选择和参与,崇尚创造性、差异性、多样性、不确定性和建构性,主张教师与学生之间应建立一种平等的对话关系。这对我国当前的教育研究及教育改革,尤其是课堂教学改革具有一定的指导意义。     

面向人与自然和谐共生的环境党内法规的治理逻辑

建设面向人与自然和谐共生的中国式现代化,中国式法治化是必然要求,其中环境法治不可或缺。中国式的环境法治必然要重视党内法规的特殊法治和治理功能。可从着力发挥党内法规在环境法治中的特殊作用、统筹推进环境综合治理的规范功能、推动构建人类环境命运共同体的制度文明三方面,揭示出环境党内法规所秉持环境系统观、环境效能观、环境文明观的政理法理。环境党内法规有广义和狭义之分,环境党内法规所承载上述治理逻辑的规范样态,不仅包括符合《中国共产党党内法规制定条例》严格形式要件的狭义党内法规,也包括引领环境法治发展的环境政策、起到监督保障等作用的党内环境规范性文件。从环境党内法规的政治功能和规范效力来讲,将以决议、决定、意见、通知等为主要载体的环境政策视为广义的环境党内法规,符合新形势下环境党内法规体系构筑的核心要义。从目前党内法规体系的构成情况看,起到监督保障作用的党内环境规范性文件成为了主力军,但其数量庞杂又单线作战的实践困境使其亟需完善以形成治理合力。因此,应进一步探讨党的环境政策和党内环境规范性文件向狭义党内法规的有机转化,使狭义的环境党内法规成为环境党内法规体系的主体部分。广义视阈下的环境党内法规,在面向人与自然和谐共生的现代化中发挥着规范、治理与重塑的制度功能。环境党内法规通过将党的不成文的环境文明提炼转化为具有约束力的制度形态,从而使其获得长远的效能力和长期的执行力。环境党内法规通过为生态文明建设提供制度赋能,从而全面发挥其环境治理的政治效能、预防效能和发展效能。环境党内法规以党的领导为本质特征的政治结构为环境文明奠基、以人民为中心的人本理念为环境文明铸魂、以党规国法共治为保障的外部制度为环境文明塑形,使其实质上具备了打造人类环境文明新形态的重塑功能。需要注意的是,完备的环境党内法规体系对上述功能的系统发挥尤为重要,因此,面向人与自然和谐共生的环境党内法规,还有待进一步体系化完善。     

A global meaning of supply chain social sustainability

Abstract

The purpose of this research is to help reduce tensions in supply chain social sustainability (SCSS) decisions by providing a common global, contextual definition of social sustainability. This exploratory study utilised an inductive structured interview method to capture SCSS concept meanings. Those interviewed are from, have lived, and worked in developed economies, emerging economies and the base of the pyramid (BOP) economies. The results present a new global baseline definition of SCSS to inform theory and practice by finding that SCSS meanings differ not only between the different levels of economic development, but also within the levels as well. Culture, community and whether basic human needs are met all weigh into perspectives of what this concept is and should entail; a broad, contingent definition is most appropriate moving forward for sustainability planning and execution. Further research with stakeholders in more countries and communities is needed to validate our proposal.     

Reconciliation with the Utility of Chance by Elaborated Outcomes Destroys the Axiomatic Basis of Expected Utility Theory

Expected utility theory does not directly deal with the utility of chance. It has been suggested in the literature (Samuelson, 1952, Markowitz, 1959) that this can be remedied by an approach which explicitly models the emotional consequences which give rise to the utility of chance. We refer to this as the elaborated outcomes approach. It is argued that the elaborated outcomes approach destroys the possibility of deriving a representation theorem based on the usual axioms of expected utility theory. This is shown with the help of an example due to Markowitz. It turns out that the space of conceivable lotteries over elaborated outcomes is too narrow to permit the application of the axioms. Moreover it is shown that a representation theorem does not hold for the example.

"人力资本论"中的劳工迁移观分析

二战结束后,随着美国科技革命的展开和经济结构中服务业的崛起,美国从20世纪50年代开始出现了经济繁荣和社会失业率并行攀升的趋势。对此,以西奥德.舒尔茨为代表的经济学家通过实践和潜心研究,提出了颇有影响的人力资本论,其中关于劳工迁移的精辟论述具有很强的历史和现实性价值,但是,其中的局限性也十分突出,尤其是强调区域工资差异的论述似有以偏概全之嫌。无论是在理论上,还是近现代史上的跨国移民以及二战后美国以劳工为核心的人口流动,都证明了该理论中的局限性。
