Ranked set sampling with unequal samples for skew distributions

A ranked set sampling procedure with unequal samples for positively skew distributions (RSSUS) is proposed and used to estimate the population mean. The estimators based on RSSUS are compared with the estimators based on ranked set sampling (RSS) and median ranked set sampling (MRSS) procedures. It is observed that the relative precisions of the estimators based on RSSUS are higher than those of the estimators based on RSS and MRSS procedures.     

论公诉案件被害人上诉权的功能

我国现行刑事诉讼法虽确定了公诉案件被害人诉讼当事人的主体地位,但没有赋予其上诉权.本文认为被害人上诉权具有纠错、防错功能,安抚、说服功能,平衡利益关系功能,保障司法终局性和权威性功能以及维护司法统一适用等功能,被害人上诉权的功能决定了赋予被害人上诉权之必要性.     

行政诉讼结构再认识

诉讼目的内在动机与价值追求造就了诉讼结构必然成为诉讼法学研究对象的逻辑结果。行政诉讼作为我国三大诉讼之一,有其独特的价值追求实现方式,由于参加行政诉讼的主体的前在特别地位殊差,使得重新剖析和认识行政诉讼结构,成为行政诉讼领域首先要梳理的争点。     

论自由心证及其公开

自由心证制度在当今世界各国得到普遍的适用。作为证据制度的重要内容,心证本身的含义、内容及表现形式,比之于传统的秘密自由心证都存在本质不同。现代心证最主要的特点就在于其抛弃了传统心证的秘密性,而成为一个开放和公开的体系,使得自由心证制度具有更强的生命力。     

Asymptotics for Statistical Treatment Rules

This paper develops asymptotic optimality theory for statistical treatment rules in smooth parametric and semiparametric models. Manski (2000, 2002, 2004) and Dehejia (2005) have argued that the problem of choosing treatments to maximize social welfare is distinct from the point estimation and hypothesis testing problems usually considered in the treatment effects literature, and advocate formal analysis of decision procedures that map empirical data into treatment choices. We develop large‐sample approximations to statistical treatment assignment problems using the limits of experiments framework. We then consider some different loss functions and derive treatment assignment rules that are asymptotically optimal under average and minmax risk criteria.     

Efficiency Bounds for Missing Data Models With Semiparametric Restrictions

This paper shows that the semiparametric efficiency bound for a parameter identified by an unconditional moment restriction with data missing at random (MAR) coincides with that of a particular augmented moment condition problem. The augmented system consists of the inverse probability weighted (IPW) original moment restriction and an additional conditional moment restriction which exhausts all other implications of the MAR assumption. The paper also investigates the value of additional semiparametric restrictions on the conditional expectation function (CEF) of the original moment function given always observed covariates. In the program evaluation context, for example, such restrictions are implied by semiparametric models for the potential outcome CEFs given baseline covariates. The efficiency bound associated with this model is shown to also coincide with that of a particular moment condition problem. Some implications of these results for estimation are briefly discussed.     

我国有效辩护制度审视与展望

被追诉人的自我辩护权和获得律师辩护权是其最重要的两项刑事诉讼权利。有效辩护制度的建立则是被追诉人辩护权保障的关键。我国刑事诉讼法修正前的辩护制度广受质疑,修正后的刑诉法虽允许被追诉人在侦查阶段即可获得律师辩护,扩大了辩护律师和被追诉人的诉讼权利范围并强化了相应保障措施,但这些修正内容的落实仍有许多悬而未决的问题。此次修改能否建立我国的有效辩护制度,尚待进一步观察。     

论公民的预算参与权及其实现

公民的预算参与权是公民通过各种合法的途径与方式参与预算事务的权利。确立并保障公民预算参与权的实现,不仅有助于公民参政议政,促进预算公平,实现人民主权,而且可以有效启动权利对权力的监督制约,推动民主的发展。目前,我国对于公民预算参与权的保障不仅法律体系不完善,而且参与途径缺失,救济渠道不畅。因而公民预算参与权在我国的实现,不仅需要健全相关立法,而且需要完善参与途径,疏通救济渠道。     

论大学生网瘾心理过程机理及心理行为矫治方法

大学生普遍具有四种主要网络心理需求,即网络求知心理需求、网络娱乐心理需求、网络交际心理需求和网络性心理需求。大学生与中学生网瘾心理过程机理大体相同,但也存在一定的特性差异。大学生网瘾是大学生心理需求异化而导致的恶性网络行为,其致瘾机理是一个从"异化"到"恶化"的过程。针对网瘾的心理过程机理,采取三种"心理—行为"方法——心理矫治法、行为干预法及行为规范法,能有效矫治大学生网瘾行为。
