Cautious Expected Utility and the Certainty Effect

Many violations of the independence axiom of expected utility can be traced to subjects' attraction to risk‐free prospects. The key axiom in this paper, negative certainty independence ([Dillenberger, 2010]), formalizes this tendency. Our main result is a utility representation of all preferences over monetary lotteries that satisfy negative certainty independence together with basic rationality postulates. Such preferences can be represented as if the agent were unsure of how to evaluate a given lottery p; instead, she has in mind a set of possible utility functions over outcomes and displays a cautious behavior: she computes the certainty equivalent of p with respect to each possible function in the set and picks the smallest one. The set of utilities is unique in a well defined sense. We show that our representation can also be derived from a “cautious” completion of an incomplete preference relation.     

职业学院和师范学院大学生自我意识发展的比较研究

为了深入了解职业院校和师范院校大学生自我意识的发展特点,本研究运用《自我意识量表》对两类两所学校664名大学生进行调查。结果发现：（1）两种院校大学生的自我意识水平总体上都处于中等,但两个维度之间发展不平衡,公众自我维度的得分显著高于内在自我维度;（2）女生在公众自我维度上显著高于男生,年龄为18岁及以下的学生在自我意识总分上显著低于其他年龄的学生;（3）师范院校大学生在公众自我维度上的得分显著高于职业院校大学生。     

行政补偿立法思考

行政赔偿在行政领域起到了重要作用,目前获得行政赔偿的必要条件之一是行政主体违法行使职权,从行政相对人的角度考虑,在是否违法问题上大费周章没有必要,进一步从行政赔偿法是救济法的本质出发,优先考虑行政相对人的权益,将有关行政补偿内容纳入行政赔偿法律体系框架之中。     

新冠肺炎疫情下对完善快递末端配送体系建设的思考——以重庆市为例

自新冠肺炎疫情发生以来,快递业为应急救援物资和人民群众日常基本生活物资运输和寄递服务、畅通经济循环、满足民生需要等方面做出了重要贡献,为疫情防控提供了强有力的支撑;但同时也暴露出了一些问题,集中体现在末端配送体系不健全、末端收投不畅等方面。在对电子商务和快递业发展现状进行分析的基础上,对快递末端配送的主要模式和发展趋势进行了论述,结合重庆市的实际情况,分析了其末端配送存在的不足,并从公共服务平台搭建、智能化无接触式配送构建、乡村快递服务网络完善、快递员队伍建设等方面提出了对策建议,以助推重庆经济社会高质量发展。

Exploring the relation between maternal mind‐mindedness and children’s symbolic play: A longitudinal study from 6 to 18 months

Relations between mothers’ mind‐mindedness (appropriate attunement to their infants’ internal states) at 6 and 12 months and infants’ early symbolic play during infant–mother pretense at 12 and 18 months were investigated in a sample of 43 mothers and infants. Mothers’ appropriate mind‐related comments were associated with average level, length, complexity, and maturity level of symbolic play. Specific sub‐categories of appropriate mind‐related comments were identified as independent predictors of children's symbolic play. Appropriate comments about desires and cognitions at 6 months were associated with average level and length of episodes, as well as with maturity level of symbolic play at 12 months. Longitudinal stability in the appropriateness and content of mothers’ mind‐related comments was also investigated. The results are discussed in terms of the proposal that attunement to specific types of internal state should vary as a function of infant age in order to index mind‐mindedness.

远海岛礁冷链物流体系优化模型及其集成算法

为研究远海岛礁渔获冷链物流的运行方案,本文选择了岛礁冷库储存中转和海上直接收购等两种不同的渔获运输方式,同时考虑了中转冷库选址、中转运输和直接收购船舶配备、航线配置、在渔场停留时间和渔获运输损耗等诸多复杂问题,构建了远海冷链物流体系组合优化模型。求解时,提出了一种以遗传算法（GA）为外部框架,以改进的模拟植物生长算法（PGSA）为内部模块,通过信息传递实现内外连接交互的集成算法。最后,以我国南海远海岛礁及渔场为实例进行分析,取得了较好效果。通过与传统遗传算法对比,本文优化结果、稳定性及计算速度等均有明显提高,从而证明了本文所建模型与算法的合理性和有效性。

显性教育与隐性教育并举增强“基础”课教学实效性

提高"思想道德修养与法律基础"课教学实效性是全社会、高校和"基础"课教师共同关心的重要问题。将显性教育与隐性教育并举,是一条行之有效的途径。显性教育要确立"以学生为本"的理念,拓展教学内容给予学生足够的现实关怀,丰富教学方式以提升学生的精神境界,改进考核方式以培养学生的自我教育能力。开展隐性教育要注重发挥教师自身的人格力量,以个性影响个性;虚功实做,在细节上关爱学生;充分利用现代新媒体,以正能量陶铸学生。
