人际信任的自我削弱与熟人社会变迁

接续阶层分化的研究路径,从农民互惠博弈内生视角出发,构建"人际信任-熟人社会"的分析框架,以揭示熟人社会变迁的微观动力机制。研究认为,小农经济的生产形态与农耕文明时期低社会生产力水平以致农民长期面临生存威胁之间的张力,催生了广布于乡村社会的互惠网络,农民人际信任的自我增强与经济互助及道德声誉制度的自我实施相互作用,生成并维系传统熟人社会及其发展。市场性的输入以经济分化和农民离村为着力点打破了这一继替格局。农民摆脱生存威胁后,其互惠付出意愿降低,进而影响博弈双方的行为选择。当信任的自我削弱使农民的制度化信念发生质变时,熟人社会逐步解体趋势难以逆转。流动性社会中,基于连接性社会网络建立新型农村社区,是乡村社会发展的重要方向。     

Coherent decision analysis with inseparable probabilities and utilities

This article explores the extent to which a decision maker's probabilities can be measured separately from his/her utilities by observing his/her acceptance of small monetary gambles. Only a partial separation is achieved: the acceptable gambles are partitioned into a set of belief gambles, which reveals probabilities distorted by marginal utilities for money, and a set of preference gambles, which reveals utilities reciprocally distorted by marginal utilities for money. However, the information in these gambles still enables us to solve the decision maker's problem: his/her utility-maximizing decision is the one that avoids arbitrage (i.e., incoherence or Dutch books).

在线双向拍卖中的不完全信息博弈仿真研究

双向拍卖机制能较好地解决在线拍卖中如何有效利用网络资源、减轻网络负荷的问题,而构造双向拍卖的报价模型和策略是其重要内容之一。从实验经济学方法的角度,构造了在线双向拍卖中不完全信息博弈下存在的贝叶斯—纳什均衡并求解,通过计算机仿真详细分析了该模型的特点和可行性,为高效利用网络资源、提高在线拍卖效率提供了可行的思路。     

高校体育社团社会责任对成员组织公民行为的影响——心理契约、组织认同的序列中介作用

为考察高校体育社团社会责任对社团成员组织公民行为的影响,以及心理契约和组织认同在它们之间的多重中介作用,采用问卷法对高校体育社团成员进行调查的结果发现:高校体育社团社会责任能够正向预测组织公民行为,心理契约与组织认同在社会责任与组织公民行为中间起中介作用。高校体育社团社会责任通过4条路径影响组织公民行为:直接作用,心理契约、组织认同的中介作用,心理契约和组织认同的序列中介作用。构建的多重中介模型在一定程度上解释了高校体育社团社会责任对社团成员组织公民行为的影响机制。研究结果表明,高校体育社团重视社会责任有助于提高社团成员心理契约和组织认同,进而提高社团成员组织公民行为。     

传统幼儿游戏在农村幼儿数学教育活动中的应用与价值

游戏是幼儿的天性,是幼儿成长发展的需要。幼儿园教育要以游戏为基本活动,寓教育于幼儿的生活、游戏活动中。农村有得天独厚的自然条件,有丰厚的传统幼儿游戏资源,将这些传统游戏应用于幼儿数学教育活动,达成幼儿数学认知目标,是将幼儿数学教育寓幼儿游戏活动路径的有益探索,在农村幼儿园现有条件下有重要的实践意义和理论价值。     

An empirical Bayes' procedure for ranking players in Ryder Cup golf

We describe a model to obtain strengths and rankings of players appearing in golf's Ryder Cup. Obtaining rankings is complicated because of two reasons. First, competitors do not compete on an equal number of occasions, with some competitors appearing too infrequently for their ranking to be estimated with any degree of certainty, and second, different competitors experience different levels of volatility in results. Our approach is to assume the competitor strengths are drawn from some common distribution. For small numbers of competitors, as is the case here, we fit the model using Monte-Carlo integration. Results suggest there is very little difference between the top performing players, though Scotland's Colin Montgomerie is estimated as the strongest Ryder Cup player.

Forms of gambling,gambling involvement and problem gambling: evidence from a Swedish population survey

The purpose of this study was to explore the association between problem gambling (PG) and participation in different forms of gambling in order to elucidate relationships between PG, gambling involvement and gambling intensity. Using data from the first wave of the Swedish Longitudinal Gambling Study (Swelogs) (n = 4,991), the study tested four hypotheses, namely that (1) some forms of gambling are more closely associated with PG than other forms; (2) high gambling involvement is associated with PG; (3) gambling involvement is positively associated with the intensity of gambling; and (4) the relationship between gambling involvement and PG is influenced by the specific forms of gambling in which individuals participate. All four hypotheses were supported. More specifically, the study found that while many PGs regularly participate in multiple forms of gambling, half of PGs participate regularly in only one or two forms of gambling. The study concluded that some forms of gambling are more closely associated with problem gambling than other forms, and that gambling policy and regulation, as well as the development of responsible gambling initiatives, should focus on these forms.
