A CONTINUOUSLY ADAPTIVE RANK TEST FOR SHIFT IN LOCATION

This paper considers the problem of testing for shift in location when the symmetry of the underlying distribution is in doubt. Various adaptive test procedures have been suggested in the literature; they are mainly based on a preliminary test or measure of asymmetry, and then choosing between the sign or the Wilcoxon tests accordingly. However, as this paper demonstrates, there are some disadvantages with such procedures. This paper develops a test that does not suffer from such disadvantages. The proposed test is based on modifying the Wilcoxon scores according to the evidence of asymmetry of the distribution present in the data as indicated by the magnitude of the P‐value from a preliminary test of symmetry. A simulation study investigates and compares the performance of the proposed test and other known adaptive procedures in terms of power and attainment of the nominal size. The performance of a suitable bootstrap procedure for the situation under consideration is also studied. In most cases under consideration, the proposed test is found to be superior to the other tests.     

A discussion on ‘Detection of intrusions in information systems by sequential change-point methods’ by Tartakovsky, Rozovskii, Blažek, and Kim

Tartakovsky et al. provide us with, and should be thanked for, an illuminating introduction to the problems of detecting intrusions and other denial of services attacks, and a thorough discussion and analysis of the relevance of CUSUM-based change detection algorithms for this purpose.This discussion mainly addresses three issues: introducing a minimum change magnitude, adaptation and tuning of CUSUM algorithms, and processing binary quantized data. The influence of the adaptation in the NP-CUSUM algorithm on its performances is questioned.     

论我国独立董事的产生机制及其权责匹配

目前我国上市公司的独立董事只是公司治理的"花瓶"。他们不但没有起到应有的作用,反而加大了公司治理成本。其原因在于这些独立董事不独立、不懂事、无实权。我国独立董事制度应从独立董事的功能定位、产生程序和权责匹配入手,保证他们的独立性,增强物质和精神激励,发挥他们的积极作用。     

论物权法中征收与征用的区别及其价值

征收与征用原本是行政法学的概念，但若干时间以来未能对其内涵和区别作出较为透彻的理论解释。《物权法》第一次对征收、征用作出较为科学的法律规定，从而对征收与征用作了明确的区分。正确把握征收与征用的异同，对于制定不同于征用的科学的征收程序、对于被征收人获得足额的事先补偿、对于社会公平正义的实现具有积极的现实意义。

Localizing ruptures in block stochastic systems

Summary In the present paper, rupture detection in a possibly complex stochastic system is enhanced by means of a procedure for localizing the actual rupture among various possible sources. A general model is considered which includes a variety oflinear and non-linear innovation based models. The proposed localizing multiple comparison procedure satisfiescoherence andconsonance and, for a wide class of models, strongly controls the familywise error i.e. the various type I error probabilities involved. The first order autoregressive optimal control model is considered as a popular example. Montecarlo simulations are performed to evaluate asymptotic approximations and diagnostic performances by means of mean time of delay and mean time between false alarms. Some conjectures are then given on the possible structure of these indicators.     

排污权交易制度的行政法思考

作为一项新兴的环境行政规制手段,排污权交易制度需要接受现代行政法上法律保留原则的约束,其顺利推行应具备信息公开、听取意见和说明理由等程序要件。排污权交易实施后政府的重新规制应重视行政登记、行政合同等事后监督型和非权力性规制方式的运用。     

地方政府行政审批程序中存在的问题及对策

为适应加入世贸组织后政府职能的转变 ,目前从中央到地方都在进行行政审批制度的改革 ,但主要集中在减少审批项目 ,缩小审批范围 ,而对审批程序的规范相对薄弱。针对这种情况 ,我们采用了问卷调查与深度访谈的形式 ,对国内一些主要城市的 60多家企业和有关审批部门 ,就行政审批程序方面存在的问题及原因进行了调研分析 ,提出了解决问题的对策建议。可以预见 ,我国行政审批制度改革发展方向必然进一步深化为行政审批程序的合法化、科学化、效能化     

A Bayesian predictive approach to determining the number of components in a mixture distribution

This paper describes a Bayesian approach to mixture modelling and a method based on predictive distribution to determine the number of components in the mixtures. The implementation is done through the use of the Gibbs sampler. The method is described through the mixtures of normal and gamma distributions. Analysis is presented in one simulated and one real data example. The Bayesian results are then compared with the likelihood approach for the two examples.     

对人民调解原则作为民事诉讼基本原则的质疑

人民调解原则在 1982年的民事诉讼法 (试行 )以及 1991年修改后的民事诉讼法中均被规定为民事诉讼法的基本原则。通过对人民调解历史发展脉络的梳理 ,以人民调解与民事诉讼基本原则属性的一一比照和阐述人民调解原则作为民事诉讼法原则同法院调解原则的重叠和冲突 ,并展望了人民调解未来的发展趋势。
