Inferences concerning interpersonal choices given anonymously

It may be difficult or impossible to make a reliable empirical investigation of an unknown network of interpersonal choices or contacts if these are in some respect sensitive for the individuals involved. We consider how choice data given anonymously can be used to reveal various features of the network. Using tools from statistical decision theory and information theory we can determine risks and capacities of disclosing choice data, the graph structure of choice data and its numbers of loops and mutuals. We give some general results, illustrate the combinatorial complexity of the problem and comment upon the computational difficulties.     

Optimal estimation of a finite population mean under generalized random permutation models

Employing certain generalized random permutation models and a general class of linear estimators of a finite population mean, it is shown that many of the conventional estimators are “optimal” in the sense of minimum average mean square error. Simple proofs are provided by using a well-known theorem on UMV estimation. The results also cover certain simple response error situations.     

Projective (2n,n,λ,1)-designs

A projective (2n,n,λ,1)-design is a set $\text{D}$ of n element subsets (called blocks) of a 2n-element set V having the properties that each element of V is a member of λ blocks and every two blocks have a non-empty intersection. This paper establishes existence and non-existence results for various projective (2n,n,λ,1)-designs and their subdesigns.     

Procedures for improving the mle for ordered binomial parameters

The problem is that of estimating the probabilities of m independent binomial random variables when their probabilities are known to be nondecreasing and the loss function is squared error. In the cases where the m.l.e. is inadmissible (essentially when the total number of trials is 7 or more) we present a method for modifying the m.l.e. to get a better estimator. The method requires a series of changes. At each step we alter the action taken by the m.l.e. on each of three, appropriately chosen, points in the sample space.     

Controlling health care costs: An evaluation of strategies

There has been much discussion about the factors underlying inflation in the health care sector and the means to moderate increases in health expenditures. This paper identifies various costcontainment strategies and synthesizes research findings that may be helpful in evaluating their effectiveness. The review demonstrates the complexity of the issues and relationships that must be confronted and understood in cost containment. The delivery system is shown to be not well-suited to improving efficiency and restraining health care expenditure. Any single strategy, whether it involves restructuring the market or more direct regulation, cannot in itself accomplish the combination of expenditure control and adequacy of services that is socially desirable. A number of mutually reinforcing strategies are required. Finally, more empirical and analytical information on incentives, provider and regulatory decisionmaking, costs of regulation, and the dynamics of negotiation, is essential for the design of an effective costcontainment program.     

A class of Shrunken estimators for normal mean

This paper presents a class of estimators for the mean of a normal population and determines the conditions on characterizing scalars under which the class of estimators uniformly dominates over the conventional sample mean according to the mean-square-error criterion.     

政治抱负和人文理想相融合的体育思想——纪念毛泽东诞辰110周年

从毛泽东体育思想的孕育和催生到他的<体育之研究>与"游泳"诗二首的发表,再到建国后毛泽东体育思想在全国的实践,都贯穿着一个中心思想,即他的政治抱负的施展和人文理想的追求是融为一体的.也是他作为一代著名政治家和领袖人物,其体育思想与他人相异之处.     

发展中国体育产业组织的理性思考

随着社会的进步,体育成为人们生活中必不可少的组成部分,由此形成了商机,出现了体育产业。根据产业组织理论,中国体育产业进入成长期,其市场结构、市场行为都不十分理想,因此,要抓住机遇,保护体育这一"幼稚产业",组建体育集团,培养体育产业管理人员,促进国内竞赛国际化,使中国体育产业走上健康发展之路。     

普通高校体育教学内容改革构想

普通高校体育教学内容在以“健康第一”及“终身健身”思想的指导下,改造竞技体育运动项目,吸取我国民族、民间传统体育,安排足够时间的体育与健康理论知识的传授。面向全体学生,调动其学习积极性,提高大学生身心健康水平与终身健身的意识。
