区间合作博弈的区间核心的研究

研究了区间合作博弈的区间核心,得出满足超可加性的2人区间合作博弈区间核心是存在的,并通过引入左、右博弈的概念,讨论了通过左、右博弈的核心来构造区间合作博弈区间核心的问题,举例说明了左、右博弈的核心可以非空而区间博弈核心可以为空。通过引入合于的概念,给出了通过左、右博弈的核心可构造区间核心的充要条件。讨论了区间核心为空时左、右博弈的核心的分离性,以及对具有非空区间核心的区间博弈进行压缩的问题,最后讨论了区间合作博弈区间核心计算问题,并用实例予以说明。     

The Role of the Statistician: Scientist or Shoe Clerk

A carnival game is described in which a player rolls eight dice or eight marbles into holes. To win, the player must obtain a favorable outcome on a number of plays. The probability distribution for the outcome of a single play is discussed. The distribution of a winning combination of outcomes is discussed and approximated. These probabilities show that the game is essentially unbeatable.     

从第29届奥运会看中国女排与比赛对手技术特征比较分析

对第29届奥运会上进入前四名的队伍的小组赛及淘汰赛阶段的比赛进行了统计。采用文献资料法、数理统计法、比较分析法,对中国女排及比赛对手的技术特征进行了比较研究。结果表明：发球得分方面与世界强队不存在显著性差异;不过在破攻方面与世界强队,仍存在着高度显著性差距;扣得分与被拦回上与世界强队不存在显著差距;但是在失误上存在着显著性差异。拦网基本上与巴西持平,与美国差距不大,稍优于古巴。一传总体效果上,中国队在一传到位、接发球及失误与巴西队存在着显著性差异;但在一传到位率上却不逊于巴西等强队;同时在垫球失误上,存在着高度显著性差异;在每局垫起能攻的次数上,平均每局比巴西约少3次。

Development of an Instrument for the Analysis of Problem Gambling Counselling Practice

This article provides an overview of the development and validation of a Counsellor Task Analysis (Problem Gambling) [CTA (PG)] instrument undertaken in order to document the activities of counsellors in problem gambling services. The CTA (PG) aims to provide a broad overview of the complexity of the counsellor's role; specify the range of tasks they perform; and document the relationship between the frequency of task performance and the counsellor's beliefs about the importance of the tasks performed. The CTA (PG) instrument addresses nine dimensions of practice activity through nine subscales, all of which demonstrate internal consistency. It appears to be a strong instrument in terms of its measurement error characteristics for recommending its use with counsellors engaged in the field of gambling. The CTA (PG) gives counsellors the opportunity to document their practice and theories in use when dealing with a problem gambler, a member of the problem gambler's family and the community at large. The psychometric findings reported in this article should be viewed as the preliminary results of an ongoing research effort and further psychometric testing is anticipated.     

不同水平马拉松运动员全程速度变化特征研究

采用文献资料和数理统计方法,对参加第29届奥运会的男女马拉松运动员比赛全程中每个5 km段落的平均速度进行了统计与分析.结果表明:男子国际健将从第6个段落开始,速度出现较大幅度下降;女子国际健将、男女健将和男女一级5个组别均从第7个段落开始,速度出现较大幅度下降.男子国际健将、男女健将和男女一级这5个组别,均表现出前半程速度高于后半程速度的特征;女子国际健将则表现出后半程速度略高于前半程速度的特征.女子国际健将组,除第1个段落的速度较低,与全程平均速度差距较大外,其他各段落的速度均接近全程平均速度,速度曲线平稳,全程跑节奏稳定,体现出"匀速跑"的特征.     

信号博弈及转轨时期商业银行信贷行为的理论解释

从信号博弈的角度解释经济转轨时期商业银行与企业之间的信贷行为，分析了转轨时期我为商业银行大量不良债权形成的微观机理；指出转轨时期的一些特殊因素使得信贷抵钾、担保等都难以成为企业对银行发出的有信息价值的信号，制度上的规定也使得信贷利率失去信号的作用。企业的信贷参与约束条件很容易得到满足，从而信贷博弈难以达成银行所期望的分离均衡。转轨时期银行的信贷参与约束条件也较容易达成，而后期较大的清算交易费用使得大量的不良债权滞留下来。     

ENDOGENOUS NETWORKS IN RANDOM POPULATION GAMES

Population learning in dynamic economies traditionally has been studied in contexts where payoff landscapes are smooth. Here, dynamic population games take place over “rugged” landscapes, where agents are uncertain about payoffs from bilateral interactions. Notably, individual payoffs from playing a binary action against everyone else are uniformly distributed over [0, 1]. This random population game leads the population to adapt over time, with agents updating both actions and partners. Agents evaluate payoffs associated to networks thanks to simple statistics of the distributions of payoffs associated to all combinations of actions performed by agents out of the interaction set. Simulations show that: (1) allowing for endogenous networks implies higher average payoff compared to static networks; (2) the statistics used to evaluate payoffs affect convergence to steady-state; and (3) for statistics MIN or MAX, the likelihood of efficient population learning strongly depends on whether agents are change-averse or not in discriminating between options delivering the same expected payoff.     

场外衍生品市场监管的演化博弈分析

金融危机使场外衍生品市场广受争议, 政府监管的缺失被认为是酿成灾难性后果的根源之一。从有限理性的角度出发, 运用演化博弈的分析框架, 对市场交易主体与政府监管主体之间的策略选择、演变轨迹及影响因素展开了讨论, 发现复制动态系统中存在5个局部均衡点, 并且在不同情形下趋向于不同的均衡点。依据模型的结论, 得出增强我国场外衍生品市场监管效率的对策建议, 包括加大监管强制效力、完善监管激励机制、降低监管成本支出、推动产品规范运行、健全市场自律机制等措施。
