基于不对称信息的医患关系演化路径及对策研究

医患关系是医疗活动中最基本的关系,直接关系到患者感知下的公立医院公益性的实现,然而近年来医患矛盾频发,医患关系成为了人们关注的热点问题。根据医患之间信息不对称的特点以及医患双方策略行为相互作用的动态性特点构建了医患博弈模型,应用演化博弈思想分析医患双方策略选择的动态演化趋势和路径,并探析对这些演化趋势起重要影响作用的因素,最后提出医患关系改善的建议以期能对当前医患关系恶化的演化趋势起到及时干预的作用。     

Reconciliation Between Muslims and Christians

“A Common Word Between Us,” an open letter from Muslim scholars to Christian leaders, is the most developed effort at Muslim‐Christian reconciliation to date. Endorsed by well‐known Muslim scholars from diverse sects and backgrounds, the letter emphasizes the central role of love of God and the Golden Rule in both religions and cites the catastrophic consequences of conflict. The signatories frame a norm of interreligious covenant for constructive collaborations, present their argument as an authoritative Islamic position, and effectively reject the clash‐of‐civilizations narrative. Using game‐theory models to articulate strategic challenges facing interreligious initiatives, this essay argues that a norm of interreligious covenant can potentially produce successful collective action in situations resembling both coordination and prisoner's dilemma games, depending on the success of norm entrepreneurship.     

The effects of music on time perception and performance of a driving game

Cassidy, G.G. & MacDonald, R.A.R. (2010). The effects of music on time perception and performance of a driving game. Scandinavian Journal of Psychology 51, 455–464. There is an established and growing body of evidence highlighting that music can influence behavior across a range of diverse domains ( Miell, MacDonald, & Hargreaves 2005 ). One area of interest is the monitoring of “internal timing mechanisms”, with features such as tempo, liking, perceived affective nature and everyday listening contexts implicated as important ( North & Hargreaves, 2008 ). The current study addresses these issues by comparing the effects of self‐selected and experimenter‐selected music (fast and slow) on actual and perceived performance of a driving game activity. Seventy participants completed three laps of a driving game in seven sound conditions: (1) silence; (2) car sounds; (3) car sounds with self‐selected music, and car sounds with experimenter‐selected music; (4) high‐arousal (70 bpm); (5) high‐arousal (130 bpm); (6) low‐arousal (70 bpm); and (7) low‐arousal (130 bpm) music. Six performance measures (time, accuracy, speed, and retrospective perception of these), and four experience measures (perceived distraction, liking, appropriateness and enjoyment) were taken. Exposure to self‐selected music resulted in overestimation of elapsed time and inaccuracy, while benefiting accuracy and experience. In contrast, exposure to experimenter‐selected music resulted in poorest performance and experience. Increasing the tempo of experimenter‐selected music resulted in faster performance and increased inaccuracy for high‐arousal music, but did not impact experience. It is suggested that personal meaning and subjective associations connected to self‐selected music promoted increased engagement with the activity, overriding detrimental effects attributed to unfamiliar, less liked and less appropriate experimenter‐selected music.     

健康投资与政府宏观卫生政策取向的经济学分析

在整体方面,经济学认为健康是劳动力与资本,是社会经济体系中最主要的生产要素;在个体方面,经济学认为健康是人力资本,是能提高消费者满足程度的耐久资本品。健康人力资本通过改善个体在劳动市场的表现,提高个人收入,并作为一种投资促进了经济增长。对我国健康投资的重点领域及政府职责作了相关政策建议。     

负性情绪抑制对社会决策行为的影响

利用心理生理实验法, 通过将情绪抑制操作引入最后通牒博弈实验范式, 探讨负性情绪抑制的主观情绪体验、生理反应及其对社会决策行为的影响。以40名大学生为被试, 采用MP150型16导生理记录仪记录皮肤电反应和心率。实验为2 (组别：情绪抑制组、自然观看组) × 2 (性别：男、女) × 2 (博弈对手：人、计算机) × 4 (分配方案：￥5：￥5、￥7：￥3、￥8：￥2、￥9：￥1)的混合设计, 其中组别和性别为被试间因素, 博弈对手和分配方案为被试内因素。结果发现：(1)对负性情绪进行抑制没有减少被试相应的主观体验, 情绪抑制使皮肤电反应性增强; (2)负性情绪抑制的主观体验和生理反应不存在性别差异; (3)在面对不公平的分配方案时, 情绪抑制组被试比自然观看组更倾向于拒绝接受。结果表明在最后通牒博弈中,情绪抑制影响回应者的行为反应,使他们更倾向于做出不理智的决策。     

从"对象"到"看"--维特根斯坦语言观的一个转变

本文试图从“对象”和“看”这两个概念出发来讨论维特根斯坦语言观的一个转变,在此讨论中,维特根斯坦有关“对象”和“看”的论述被置于其前后期思想的大背景中来加以考察。文章首先考察了维特根斯坦前期思想在“对象”这个概念上所面临的困难与错误,这种困难与错误构成了对其前期图像论语言观的挑战。接着,文章考察了维特根斯坦对图画所做的分析,认为图画的要点不在于它所指称的对象,而在于它如何被看,而如何被看实际上是“看”这个词的如何被使用。在此考察中,其后期游戏论的语言观得到了探讨。     

Overlap in Facebook Profiles Reflects Relationship Closeness

We assessed the association between self-reported Inclusion of Other in the Self (IOS) and Facebook overlap. Ninety-two participants completed online measures of IOS and investment model constructs. Researchers then recorded Facebook data from participants’ profile pages. Results from multilevel models revealed that IOS predicted Facebook overlap. Furthermore, Facebook overlap was associated with commitment and investment in ways comparable to self-reported IOS. These findings suggest that overlap in Facebook profiles can be used to measure relationship closeness.     

The Advantage of Democratic Peer Punishment in Sustaining Cooperation within Groups

In social dilemma situations, individuals benefit from uncooperative behavior while exploiting resources of the collective. One prominent solution to prevent uncooperative behavior and to increase cooperation is to establish a system of costly peer punishment, that is, the possibility for every individual involved in the dilemma to impose costly punishment on interaction partners. However, recent research revealed that, in contrast to a situation without punishment, peer punishment is inefficient and maladaptive in the sense that the total payoff is reduced and punishment of cooperative individuals (i.e., antisocial punishment) is possible. In the present work, we propose that a system of democratic peer punishment, that is, direct and equal participation of each individual in the punishment decision‐making process with punishment only executed when a majority has voted for its execution, can address the shortcomings of a peer punishment system. Using iterated public goods games, we show higher cooperation levels, higher total payoffs, and reduced executed punishment in the democratic compared with a peer punishment system. Moreover, we document that fairness perceptions, satisfaction, and interpersonal trust are increased in the democratic punishment system. Implications for how cooperation and democratic punishment systems may evolve are discussed. Copyright © 2018 John Wiley & Sons, Ltd.     

The rich get richer,the poor get even: Perceived socioeconomic position influences micro‐social distributions of wealth

Economic inequality has a robust negative effect on a range of important societal outcomes, including health, wellbeing, and education. Yet, it remains insufficiently understood why, how, and by whom unequal systems tend to be perpetuated. In two studies we examine whether psychological mindsets adopted by the wealthy and the poor in their micro‐social transactions act to perpetuate or challenge inequality. We hypothesized that occupying a wealthier socioeconomic position promotes the pursuit of self‐interest and contributes to inequality maintenance; poorer socioeconomic position, on the other hand, should promote the pursuit of fairness and equality restoration. In Study 1, participants completed an ultimatum game as proposers after being primed to believe they are wealthier or poorer, offering money to either poor or wealthy responders. As expected, the wealthy pursued their self‐interest and the net effect of this behavior contributes to the maintenance of inequality. Conversely, the poor pursued fairness and the net effect of this behavior challenges inequality. In Study 2, participants were responders deciding whether to accept or reject unfair distributions. Compared to the wealthier, the poorer challenged inequality by rejecting unequal offers. The links between micro‐social processes and macro‐societal inequality are discussed.
