试论强化纪检监察部门信访监督的法律意识

党中央、国务院在《关于加强新时期信访工作的意见》中从三个方面给信访工作作了科学的定位。根据这个定位,纪检监察部门的信访监督至少拥有九个途径,与党委政府信访部门的监督存在六方面的不同。至于如何强化纪检监察部门信访监督的法律意识,就必须做到用法律的眼光审视每一起信访件,以法律的视角保护好信访监督人的合法权益,用法律的理念去构建动态的信访监督信用体系,用法律思维审视信访"泛作为"和"不作为"情况。     

A simulation study on power comparisons for group sequential tests of non-parametric statistics

In this article, a group sequential test (GST) of non-parametric statistics for survival data is briefly reviewed. An asymptotic joint distribution of the test statistics, obtained after each interim analysis, is given to illustrate the applicability of the critical values of the GST procedures. It should be noted that censored observations are generally seen in survival data. Therefore, if one makes power calculations irrespective of censoring, reliable results may not be achieved, due to the lack of information about the censoring structure. A wide simulation study, covering different censoring rates and tied observations, is conducted to make the power comparisons under various scenarios. The simulation results are interpreted and compared with the results obtained by using power analysis and sample size (PASS) software.     

A survey of permutation tests for censored survival data

The present paper surveys tests with censored sur-vival data for 2-and k-samples and for association by a framework which classifies them into complete or restric-ted permutation tests and into tests based on U-or Savage-scores. The formulae of the resulting twelve tests are briefly described for quick reference. Some of the tests have been applied frequently in the past as the tests by Mantel, Breslow or Gehan; others have been developed rather recently, partly by the author. The concluding discussion presents the results of a simulation study, clarifying similarities and differences of the restricted and complete permutation approach, and deals with rela-tive efficiencies of the two scoring systems.     

乡土世界中的女性悲歌——萧红小说中底层女性的生存悲剧

崛起于30年代的萧红就像一颗灿烂耀眼的新星在中国现代文坛上大放异彩。在她的文学创作中，是从女性的生育苦难和爱情、婚姻悲剧三方面来展现北方农村底层妇女的生存悲剧，从而阐释出女性在男权话语系统下的卑下地位。而这种别具风格的叙说方式与萧红自身的生命体验有着极其密切的联系。     

Semiparametric median residual life model and inference

For randomly censored data, the authors propose a general class of semiparametric median residual life models. They incorporate covariates in a generalized linear form while leaving the baseline median residual life function completely unspecified. Despite the non‐identifiability of the survival function for a given median residual life function, a simple and natural procedure is proposed to estimate the regression parameters and the baseline median residual life function. The authors derive the asymptotic properties for the estimators, and demonstrate the numerical performance of the proposed method through simulation studies. The median residual life model can be easily generalized to model other quantiles, and the estimation method can also be applied to the mean residual life model.

On the moment generating functions for integer valued random variables

Abstract

In this note, we give explicit expressions of moment generating functions for integer valued random variables in both univariate and multivariate cases, which extend the results obtained by Nadarajah and Mitov [Communications in Statistics–Theory and Methods, 32, 2003, 47–60] and more recently by Chakraborti, Jardim and Epprecht [The American Statistician, 2017], Kwong and Nadarajah [Communications in Statistics–Theory and Methods, 2017]. Some examples are also discussed.     

农村人口流迁动因研究评说

关于乡—城人口流迁的动因,历来为国内外学者所重视,研究成果颇多。那么迄今为止,都有哪些关于人口流迁动因的理论和观点?这些理论和观点能否完全解释20世纪80年代中后期中国的农村人口流迁现象?这些众多的理论和观点可以概括为三种:第一,宏观社会结构影响说;第二,生存与发展困境说;第三,劳动力剩余说。这三派观点各自都在自己所限定的范围内从一般意义上较为可信地解释了农村人口流迁的原因,但是由于方法论上的整体主义与个体主义的矛盾等原因,这些观点又有其局限性,因此,我们在借鉴这些观点解释20世纪80年代中后期以来中国农民的流迁动因的时候,应持审慎的态度。     

Errors in inspection and grading distributional aspects ofscreening and merarchal screening

Continuing the studies of Johnson et al (1980) and Johnson and Kotz (1981), further distributions arising from models of errors in inspection and grading of samples from finite, possibly stratified lots are obtained. Screening, and hierarchal screening forms of inspection are also considered, and the effects of errors on the advantages of these techniques assessed.
