通用考试系统开发现状及其解决方案

目前国内通用考试系统的开发与研究,主要存在的问题是通用性不强及其他信息系统的交互性不好。采用模块叠加和替换的方法,以XML作为各个模块间数据交互的标准,能较好解决通用性和交互性问题。     

Designing Experiments with Respect to 'Standardized' Optimality Criteria

We introduce a new class of `standardized' optimality criteria which depend on `standardized' covariances of the least squares estimators and provide an alternative to the commonly used criteria in design theory. Besides a nice statistical interpretation the new criteria satisfy an extremely useful invariance property which allows an easy calculation of optimal designs on many linearly transformed design spaces.

现代汉语规范化依据的定量分析

针对学界关于现代汉语规范化依据（基本原则）的分歧情况,选取有代表性的分析样本,在详细归纳规范化依据类型基础上,定量统计各类依据的使用情况,并引入＂在境＂和＂离境＂两个概念对统计数据做出定性分析,我们可以得出以下结论：基于理性原则的在境依据是规范化的基本依据,基于习性原则的离境依据只能作为一种参考。在现代汉语规范化过程中,应该将基于现实同一性在境分析的理性原则作为基本原则。     

Identification of Multiple Outliers in Logistic Regression

The use of logistic regression modeling has seen a great deal of attention in the literature in recent years. This includes all aspects of the logistic regression model including the identification of outliers. A variety of methods for the identification of outliers, such as the standardized Pearson residuals, are now available in the literature. These methods, however, are successful only if the data contain a single outlier. In the presence of multiple outliers in the data, which is often the case in practice, these methods fail to detect the outliers. This is due to the well-known problems of masking (false negative) and swamping (false positive) effects. In this article, we propose a new method for the identification of multiple outliers in logistic regression. We develop a generalized version of standardized Pearson residuals based on group deletion and then propose a technique for identifying multiple outliers. The performance of the proposed method is then investigated through several examples.     

中国公共服务标准化成效与困境——以民政标准化为例

作为实现公共服务均等化的重要手段和技术依据,中国民政标准化的标准制修定和实施层面均存在众多问题,对标准化、社会管理、公共服务标准化等概念进行界定,对以民政标准化为中心的中国公共服务标准化的发展和困境进行分析论证。研究认为,2005年以来中国民政标准化机构在国家层面形成了较为完善的工作体系,民政部制定的标准化政策在社会管理和公共服务领域开始普遍使用,结合实际完成制修订国家标准和行业标准并在全国民政社会服务领域普遍实施;在当前中国公共服务标准化存在困境的背景下,应加强政府等管理部门的标准化意识,提高标准化工作进程,均衡国家与行业标准使其能涵盖到民政的各个领域,还应完善民政标准化的组织和实施体系,健全民政等级评定、合格评定以及示范建设等方面的管理标准。     

Optimal designs for the Michaelis–Menten model with correlated observations

In this paper we investigate the problem of designing experiments for generalized least-squares analysis in the Michaelis–Menten model. We study the structure of exact D-optimal designs in a model with an autoregressive error structure. Explicit results for locally D-optimal designs are derived for the case where two observations can be taken per subject. Additionally standardized maximin D-optimal designs are obtained in this case. The results illustrate the enormous difficulties to find exact optimal designs explicitly for nonlinear regression models with correlated observations.     

Approximate variance formulas and asymptotic joint sampling distributions of standardized risk ratios in the presence of competing risks in cohort studies

The present paper is concerned with some results in cohort studies, in which the individuals in two study population are exposed simultaneously to several risks of death, which compete for their lives.

The morality experience of individuals in the two study populations is compared with respect to the morality experience of individuals in a well-defined and fixed population called the standard population.

Under some reasonable assumptions, not only simple variance formulas are-developed for the standardized risk ratio statistics (S[Rcirc]R_i) but also their joint asymptotic sampling distribution. It is demonstrated that these SRcirc;R_i's have asymptotically a multivariate normal distribtion corresponding to any given number of competing risks of death, These results are utilized to construct Scheffé-type and Sidak-type simultaneous confidence intervals for the SRR_i parameters which hold regardless of any covariance structure among the competing risks of death. The corresponding results for the cause-specific SMR and the externally standardized risk ratio parameters follow as special cases.

The present paper generalizes the available results in the literature in two directions, namely, to obtain simple variance formulas for the S[Rcirc]R_i, statistics and to treat the situation in the presence of competing risks to which individuals in a study are simultaneously exposed.

An empirical evaluation of these results is discussed in the last section utilizing some real cohort data from two recent occupational epidemiologic cohort studies.     

我国政务公开的实现途径研究

政务公开在我国行政管理体制改革和行政现代化进程中有着不可忽视的地位和作用.为了回应十六大报告提出的深化行政管理体制改革的要求,就必须解决政务公开推行过程中存在的许多不规范问题.本文主要从思想理念、法律依据、监督机制、技术手段和经验借鉴等五个方面对政务公开进一步的规范化发展作了构想,提出了一些建议性对策.
