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.     

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。     

平台权力法律关系的理论构造与规范控制

平台运营方、双方或多方用户间形成的平台权力法律关系的非对称性是导致互联网平台上诸多问题发生的根源。平台权力是平台权力法律关系的决定性要素,其本质是平台基于“看门人”地位、纵向整合能力和信息不对称的优势而获得的社会权力。平台权力的存在,使得平台权力法律关系在内部构造（平台权力关系）中表现为平台对用户的支配关系;用户条款的存在,使得这种支配关系在外部构造（平台法律关系）中被转化并确认为一种平等的合同关系。应当承认用户条款的社区公约地位,加强以用户条款为核心的、由平台与用户共同参与的平台自治,规范平台权力的行使,对用户条款进行备案审查并制定示范性文本。     

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.     

Emotion Regulation in Low-income Preschoolers

The present study was concerned with identifying the causes of low-income preschoolers' negative emotions and their most common regulation responses. The relations of family socialization practices and temperament to the children's emotion regulation skills were also examined. Ninety predominantly minority low-income preschoolers (46 boys) and their mothers participated. During visits to the children's preschools, observers watched for expressions of anger and sadness, and recorded the causes of the displays and the children's reactions. Mothers reported on their emotion socialization and discipline practices and their children's temperament. Although the children expressed more anger than sadness, they used more constructive reactions in response to sadness and more non-constructive reactions in response to anger. Maternal reports of appropriate family emotion were associated with low levels of non-constructive regulation responses to anger and sadness whereas reports of inconsistent parental discipline were generally associated with non-constructive regulation responses. All in all, the findings of this study are in accord with findings on middle-income children and indicate that low- and middle-income children are more alike than different with regard to the regulation of negative emotion in the peer environment.     

"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。     

皮亚杰的道德责任发生论及其教育意蕴

皮亚杰首次利用实验方法,从个体心理发展的微观角度,揭示了儿童的道德责任的发生过程和机制。道德责任是个体社会化的产物,经历了由他律的客观责任向自律的主观责任的进化。真正的道德责任产生于协作。皮亚杰的道德责任发生论对道德教育理论与实践的启示是:道德教育必须以自由为基础,充分利用学生的自主活动,才能教会学生负责。     

从动态顺应看《李尔王》的三种译本

Jef Verschueren的语用综论观下的顺应论的动态性认为,语言选择过程的动态顺应可以从三个方面得到体现:时间顺应、语境的顺应和语言线性结构的灵活变化。以该理论对《李尔王》三个不同时期的译本进行分析,指出翻译标准应该被不断地重新阐释以顺应不同时间、不同语境和不同交际目的。     

上市公司ESG信息强制性披露：制度优势、法理基础与实现路径

随着ESG投资的兴起,上市公司ESG信息应否强制性披露成为全球主要资本市场的重要议题。ESG信息强制性披露有降低信息成本和提高信息质量的制度优势,但我国选择该模式并将其制度化的法理基础及实现路径还有待探讨。社会系统论视角下风险规制的需要和证券法中信息“重大性”标准的适用可成为ESG信息强制性披露的正当性基础。ESG信息强制性披露制度的构建,可在将重要ESG信息解释为证券法框架下重大信息的基础上,通过证监会制定基本原则、证券交易所设计具体规则形成结构化披露规则体系;宜区分以满足投资者决策需要为中心的ESG理念和以关照利益相关者诉求为核心的公司社会责任理念,分两步建立ESG信息披露框架和标准;充分考虑上市公司合规成本,推行渐进式实现方案。
