Focal points in pure coordination games: An experimental investigation

This paper reports an experimental investigation of the hypothesis that in coordination games, players draw on shared concepts of salience to identify focal points on which they can coordinate. The experiment involves games in which equilibria can be distinguished from one another only in terms of the way strategies are labelled. The games are designed to test a number of specific hypotheses about the determinants of salience. These hypotheses are generally confirmed by the results of the experiment.     

从法律的角度看新公共管理

二十世纪七十年代末八十年代初首先启端于英美国家的新公共管理已经成为概括西方公共管理最新发展趋势的一个学术概念,并且在理论上和实践上得到了迅速发展.但是,新公共管理理论或者称之为新公共管理改革基本上都发生在英、美、澳、新西兰等盎格鲁-撒克逊体系的国家.本文试图从法学的角度找出其原因.英美法系和大陆法系之划分是法学中公认的法律分类法;而新公共管理中的核心思想是利用私法契约来提供公共服务.本文通过对两大法系和契约制度的分析,认为作为大陆法系的我国基于政治法律传统应该选择法治国家模式进行政府管理改革.     

A Test for Independence of Competing Risks with Discrete Failure Times

The identifiability problem in Competing Risks is well known. In particular, it implies that independent action or otherwise of the risks cannot be inferred from data alone. However, Crowder (1996) showed that, in the case of purely discrete failure times, an inference can be made. An algebraic criterion was derived which bears essentially on the independence in question. The condition was presented in a theoretical setting but it was pointed out that the quantities involved can be estimated from data and that, therefore, there is the potential to develop practical tests for the hypothesis of independence. It is the purpose of this paper to construct such a test. This revised version was published online in July 2006 with corrections to the Cover Date.     

TESTING HYPOTHESES ABOUT THE COMMON MEAN OF TWO NORMAL POPULATIONS

Three tests are considered concerning the common mean of two normal populations: (1) an F test based on a sample from one population, (2) a test based on the addition of the F statistics from independent samples from two popultions (proposed), and (3) a test based on the maximum of the F statistics from two independent samples from two populations. A condition under which test (2) is locally more powerful than test (1) is given. As the test statistic in test (2) does not follow a standard distribution, a formula for approximating the observed significance level is provided. A simulation study is used to compare the power of these tests.

从两类性别符号到标志设计

在日常生活中 ,同一概念在不同场合以不同的符号表达、展示。这些不同符号的形成、固定并非偶然 ,皆有根可寻 ,正是它们的根源造成了其特性、应用范围的差异。这些符号的形成及应用的思维方式为标志设计拓宽了道路。     

Testing hypotheses about the common mean of normal distributions

An overview of hypothesis testing for the common mean of independent normal distributions is given. The case of two populations is studied in detail. A number of different types of tests are studied. Among them are a test based on the maximum of the two available t-tests, Fisher's combined test, a test based on Graybill–Deal's estimator, an approximation to the likelihood ratio test, and some tests derived using some Bayesian considerations for improper priors along with intuitive considerations. Based on some theoretical findings and mostly based on a Monte Carlo study the conclusions are that for the most part the Bayes-intuitive type tests are superior and can be recommended. When the variances of the populations are close the approximate likelihood ratio test does best.     

现代日汉语言比较纲要(Ⅰ)

本文是从现代日、汉语言的异同点出发，对两种语言进行比较研究的纲要。这种比较不是两种语言共同点和不同点的全部，只是简要地就两种语言(侧重语法)的主要特点的比较。本文分Ⅰ、Ⅱ两部分，第1部分从18个方面比较了两种语言的共同点，第Ⅱ部分从15个方面比较了两种语言的不同点。
