Generalized type theorems in topological spaces with applications

In this work, some new generalized type theorems for generalized mappings with compactly open values are established in topological spaces without any convexity assumptions. As applications, a Ky Fan type matching theorem, fixed point theorem and coincidence theorem are obtained in topological spaces. These results generalize some known results from the recent literature.     

A class of estimators with estimated optimum values in sample surveys

Srivastava and Jhajj (1981) proposed a class of estimators for population mean of a character using auxiliary information and optimum values involving unknown parameters. From the practical point of view, their results have very little utility. In view of practical utility, we propose a class of estimators with estimated optimum values. Further, it is shown that the proposed class with estimated optimum values attains the same minimum mean square error of the class of estimators based on optimum values.     

Coherent multiperiod risk adjusted values and Bellman’s principle

Starting with a time-0 coherent risk measure defined for “value processes”, we also define risk measurement processes. Two other constructions of measurement processes are given in terms of sets of test probabilities. These latter constructions are identical and are related to the former construction when the sets fulfill a stability condition also met in multiperiod treatment of ambiguity as in decision-making. We finally deduce risk measurements for the final value of locked-in positions and repeat a warning concerning Tail-Value-at-Risk.     

基于经验估费的二阶段最优保险契约模型

经验估费是保险人通过调整保费来修匀保单组合的风险异质性的精算技术.由于缺少对投保人和保险人的价值判断的考虑,容易诱发投保人的"奖金饥渴症"等副作用.由保费和赔付构成的保险契约,抽象了投保人和保险人的博弈关系,反映了二者的行为偏好.为此,提出以契约调整为核心的经验估费系统,依托委托-代理理论,针对有无道德风险的情况构建分析模型,对照分析最优保险契约的性质.     

知识库中的空值初探

分析了空值环境下的三种类型的查询策略，以及Ｄａｔａｌｏｇ查询求值的Ｓｅｍｉ－Ｎａｖｉｅ算法，给出了一个从子目标关系空值特性导出头关系空值特性的一种方法，使改进后的Ｓｅｍｉ－Ｎａｉｖｅ算法能在带有空值的ＥＤＢ数据中对Ｄａｔａｌｏｇ查询进行正确求值。     

Biprobabilistic values for bicooperative games

The present paper introduces bicooperative games and develops some general values on the vector space of these games. First, we define biprobabilistic values for bicooperative games and observe in detail the axioms that characterize such values. Following the work of Weber [R.J. Weber, Probabilistic values for games, in: A.E. Roth (Ed.), The Shapley Value: Essays in Honor of Lloyd S. Shapley Cambridge University Press, Cambridge, 1988, pp. 101–119], these axioms are sequentially introduced observing the repercussions they have on the value expression. Moreover, compatible-order values are introduced and there is shown the relationship between these values and efficient values such that their components are biprobabilistic values.

论邓小平价值观的时代特色

分析了邓小平的价值观，认为其时代特色之一就是对毛泽东人民利益观的发展：对价值主体的升华；对价值标准的深化；对价值选择的丰富；对价值目标的发展。     

大学文化建设中的网络道德教育

网络的普及、信息高速公路的迅猛发展对大学生开阔视野、拓宽知识领域起到了积极的促进作用,但同时也冲击着青年学生的世界观、人生观、价值观和道德观。本文分析了网络道德教育在大学文化建设中的地位和作用,找出了加强大学生网络道德教育的措施。     

西部大学生道德意识与道德行为现状及相关性研究

本项研究对教育部重大攻关项目(2003—2006)"中国公民人文素质调查与对策研究"中,有关中国西部6个省市(广西、云南、贵州、四川、重庆、西藏)的高校大学本科生群体423名调查对象的道德意识与道德行为数据进行了统计和相关性分析,并与全国大学生群体样本1090人进行比较分析。针对西部地区大学生道德意识与道德行为存在的问题,提出了建议和对策。
