Fitting in: Group effects and the evolution of fundamentalism

We provide an evolutionary model of conflict based on dyadic interactions within and between individuals drawn from a society containing fundamentalists and “others.” Thus, the paper presents an asymmetric game representation of group effects. Fundamentalist control of society is inversely related to the degree of social stratification, and fundamentalists’ intolerance of others. If, however, fundamentalism can be feigned (by displaying certain traits), then fundamentalists must balance their intolerance and insularity to take power. The model provides a novel means for distinguishing democratic versus open societies. This leads to a central result characterizing how fair and open societies can peacefully contravene fundamentalism.     

北京田径竞技实力分析

运用文献资料和数理统计等方法,对北京历届全运田径竞技特征进行全面分析和研究。结果显示:在第6—10届全运会田径竞技中,北京田径竞技实力较弱,田径水平的发展与其整体竞技水平不相称;跳高、铅球、110米栏、400米和4×400米为其优势项目,但全运制胜项目只有跳高,提示北京必须对田径项目予以重视并加快其发展速度。     

网络游戏政策的作用机制

网络游戏作为信息产业的重要组成部分在我国的发展迅速。它在给厂商带来了收益的同时,也带来了一些社会问题。为此,政府相继出台了一些政策进行规范。由于网络游戏的特殊性,对这些政策效果的分析就显得尤为重要。只有通过对相关各方行为的分析,我们才能为网络游戏的健康发展提出配套的解决方案。     

An Empirical Comparison of Probabilistic Coalition Structure Theories in 3-Person Sidepayment Games

This article reports a comparative test of the central-union theory vis-à-vis several other game-theoretic solution concepts in 3-person sidepayment games. Based on a laboratory experiment, this comparison utilizes nine games in characteristic function form. The solution concepts under test include the equal excess model, the Myerson–Shapley solution, the kernel, and two variants of the central-union theory (CU-1 and CU-2). With regard to the player's payoffs, results show that the CU-1, CU-2, kernel, and equal excess theories have essentially equal predictive accuracy and that all of these are more accurate than Myerson–Shapley. When the solution concepts are extended and coalition structure probability predictions are incorporated in the test, one version of the central-union theory (CU-2) is overall more accurate than the other solutions.     

论儿童游戏的生活本质

游戏之所以是儿童的生活 ,这绝不仅仅是因为游戏的活动自然地占据了儿童大部分的活动时间 ,抑或儿童大部分活动的发生和进行都是以游戏的形式或心态。在根本上 ,这是因为游戏的实质就是儿童的生活。游戏不仅产生并发展于生活 ,更为重要的是游戏赋予儿童以童年的生活、有灵性的生活。因此 ,游戏之于早期教育的价值就是使教育向儿童有灵性的生活回归     

薪酬管理中不公平事件受益人的控制博弈分析

把博弈论的知识应用到企业薪酬管理中,通过建立一个两人零和博弈模型,分析企业薪酬管理中对不公平事件受益人在不同情况下应采取的最优策略,得出了不公平事件发生时,企业应该在何时检查和控制的一个定量标准,以减少不公平事件的发生,维护和激励员工的工作积极性。     

解释制度的两个因素：功能和深层结构

在经济学、人类学与社会学领域．解释制度的因素主要有两类。即功能的因素和深层结构的因素。这两类因素可以结合起来形成完整的解释框架。即面对具体的制度现象．我们首先从功能的角度和深层结构的角度寻找解释这一制度的一般化因素,然后再建立博弈模型．以便在这两类一般化因素与需要解释的特殊制度现象之间建立逻辑联系。

An Efficient Dynamic Mechanism

This paper constructs an efficient, budget‐balanced, Bayesian incentive‐compatible mechanism for a general dynamic environment with quasilinear payoffs in which agents observe private information and decisions are made over countably many periods. First, under the assumption of “private values” (other agents' private information does not directly affect an agent's payoffs), we construct an efficient, ex post incentive‐compatible mechanism, which is not budget‐balanced. Second, under the assumption of “independent types” (the distribution of each agent's private information is not directly affected by other agents' private information), we show how the budget can be balanced without compromising agents' incentives. Finally, we show that the mechanism can be made self‐enforcing when agents are sufficiently patient and the induced stochastic process over types is an ergodic finite Markov chain.     

电子游戏性别刻板印象广告的消费者反应研究

随着电子游戏市场的发展,女性玩家逐渐成为游戏公司不容忽视的消费群体。然而,电子游戏广告中的性别刻板印象并未随之减少。通过使用带有性别刻板印象广告的问卷与没有性别刻板印象广告的问卷,分别调研消费者对电子游戏性别刻板印象广告的反应。采用描述统计分析、相关性分析、多元线性回归分析以及协变量的变异数分析等统计研究方法对调研数据进行解析,结果表明：消费者对于没有性别刻板印象的广告反应优于有性别刻板印象的广告。游戏广告创作需与电子游戏发展趋势相匹配,通过减少电子游戏广告中的性别刻板印象来提高消费者的情绪愉悦程度、降低消费者的广告批判态度。
