积分循环赛在学校篮球竞赛中的应用研究

为了在学校篮球竞赛中引入积分循环赛，文章针对棋类积分编排存在的三个方面问题，通过采用每轮比赛排名作为配对排序的条件，并对棋类积分编排方法进行了一定的简化移植，经过多次试验性编排，运用电子表格技术设计出了一整套篮球积分编排方法。这种方法可实际运用于篮球积分循环赛的手工编排，并能为实现计算机篮球积分编排提供理论依据。     

Asymptotically optimal estimation of smooth functionals for interval censoring, part 1

Estimation in the interval censoring model is considered. A class of smooth functionals is introduced, of which the mean is an example. The asymptotic information lower bound for such functionals can be represented as an inner product of two functions. In case 1, i.e. one observation time per unobservable event time, both functions can be given explicitly. We mainly consider case 2, with two observation times for each unobservable event time, in the situation that the observation times can not become arbitrarily close to each other. For case 2, one of the functions in the inner product can only be given implicitly as solution to a Fredholm integral equation. We study properties of this solution and, in a sequel to this paper, prove that the nonparametric maximum likelihood estimator of the functional asymptotically reaches the information lower bound.

城市的更新、改造是社会发展的必然 ,如何通过现状调查、分析、研讨 ,找出城市建设的症结 ,使城市趋于完美是城市建设者的历史使命。但现实中 ,片面追求经济效益 ,发旧城改造之财 ,只能使城市变成“崭新的旧城” ,只有按城市发展的固有规律去完善城市的整体功能才是旧城改造的发展方向。     

Polyhedral Combinatorics in Combinatorial Optimization

Polyhedral combinatorics is a subarea of combinatorial optimization of increasing practical importance. It deals with the application of the theory of linear systems and linear algebra to combinatorial problems. The paper is not intended as a survey on polyhedral combinatorics but it reviews some of the main concepts and proof techniques.

中期财务报告准则的比较研究

为提高上市公司会计信息质量，更好地保护投资者利益，2001年11月，财政部发布了《企业会计准则——中期财务报告》。鉴于美国是实行中期报告制度最早的国家，其制度也相对完善，本文拟将我国中期财务报准则同美国的相关准则及国际会计准则IAS34作粗浅的比较分析。通过比较分析，借鉴国外准则之长处，有利于推动我国中期报告理论和实务的发展。

Modelling of repairable systems with various degrees of repair

The availability of a stochastic repairable system depends on the failure behaviour and on repair strategies. In this paper, we deal with a general repair model for a system using auxiliary counting processes and corresponding intensities which include various degrees of repair (between minimal repair and perfect repair). For determining the model parameters we need estimators depending on failure times and repair times: maximum likelihood (ML) estimator and Bayes estimators are considered. Special results are obtained by the use of Weibull-type intensities and random observation times.     

Measuring Inequalities without Linearity in Envy: Choquet Integrals for Symmetric Capacities

The (generalized) Gini indices rely on the social welfare function of a decision maker who behaves in accordance with Yaari's model, with a function f that transforms frequencies. This SWF can also be represented as the weighted sum of the welfare of all the possible coalitions in the society, where the welfare of a coalition is defined as the income of the worst-off member of that coalition. We provide a set of axioms (Ak) and prove that the three following statements are equivalent: (i) the decision maker respects (Ak), (ii) f is a polynomial of degree k, (iii) the weight of all coalitions with more than k members is equal to zero.
