Simultaneous decomposition of the variance by sources and subgroups – new insights

There are two types of decompositions: of linear combinations of random variables into contributions of individual variables (sources) and associations between them, and of populations into contributions of their subpopulations. Simultaneous treatment of the two types is called for, which takes into account the correlations between sources within subpopulations and between subpopulation means. The expected values of the subcomponents are derived and their sensitivity to correlations among sources within groups and among source group means is conducted. An example is provided, in which the correlations contribute 20--25% to total variability. This additional information is hidden when decompositions are not simultaneous.     

政府应急处理中的人权保障——以比例原则为视角

作为我国行政应急管理的基本法,《突发事件应对法》通过构建紧急状态下国家和公民活动规则的基本原则与框架,尊重和保持非常时期下的宪法民主制度和公民权利,从而维系宪法保障人权的基本价值。有效处理突发事件要求政府在紧急状态中享有应急特权,而应急权的行使当然应以比例原则来加以规制。我国的《突发事件应对法》对比例原则进行了明确规定,通过其合理适用,比例原则将有力促进政府应急处置权与公民权利之间的平衡,实现法治国家在紧急状态下的人权保障。     

法院如何回应民意:一种法学方法论上的解决方案

围绕司法与民意的讨论,目前各界存在原因认知、概念认知、价值认知上的观点错位,影响民众对司法回应的肯定.作为法律适用机关的法院在回应民意上具有不同于政治机关的特点,必须以一种理性、中立的态度审慎地回应民意,做到有理有节、有所为有所不为.在回应过程中,应当根据民意的特点着重处理法意与民意、社会民意与权力意志之间的矛盾冲突关系,为此,必须在回应民意的时机选择与方法操作上遵循司法活动的基本规律.通过认定疑难案件的程序操作,使得外在的民意得以稳定化,以程序阻隔"舆论暴力";通过法律论证的操作,以普遍化、一致性与融贯性三原则检验与提升民意本身的合理性程度,以方法压缩个人恣意.法院的回应是对成熟且理性的民意的回应,建立在个案基础上的回应能逐步挽回民众对法院的信任.     

Increasing Vocal Variability in Children with Autism Using a Lag Schedule of Reinforcement

Variability has been demonstrated to be an operant dimension of behavior (Neuringer, 2002; Page & Neuringer, 1985). Recently, lag schedules have been used to demonstrate operant variability of verbal behavior in persons with a diagnosis of autism (e.g., Lee, McComas, & Jawor, 2002). The current study evaluated the effects of a Lag 1 schedule on the vocal variability of 2 nonverbal children with a diagnosis of autism. Results showed systematic increases in variability during the Lag 1 schedule. Implications of lag schedules for speech and language training are discussed.     

Designs for estimating the difference between two responses

In this paper the problem of designing experiments for estimating the difference between responses at two arbitrary points in the region of interest is considered. Under the average mean squared error criterion the design moment conditions have been worked out. The results have been applied to the class of central composite designs.     

A process capability index with reliable confidence intervals

A well-know process capability index is slightly modified in this article to provide a new measure of process capability which takes account of the process location and variability, and for which point estimator and confidence intervals do exist that are insensitive to departures from the assumption of normal variability. Two examples of applications based on real data are presented.     

Statistical evaluation of individual bioequivalence

Drug switchability requires the evidence of individual bioequivalence which -refers to the comparison of the closeness between the two distributions of the pharmacokinetic (PK) responses from the same subject obtained under the repeated administrations of the test and reference formulations. Advantages and drawbacks of the current statistical procedures for assessment of individual bioequivalence are discussed with emphasis on the aggregate-based criteria, An intersection-union test based on disaggregate criteria is proposed for the evaluation of individual bioequivalence. In addition, a modified aggregated criterion is suggested to overcome the drawbacks suffered by aggregate criteria. The relationships among different criteria are examined, and the performance of the procedures will be compared. A numerical example is given to illustrate the proposed procedures.     

缩短供应链多阶响应周期的物流模式研究

为了满足最终客户的多样化、及时化的需求,供应链的物流模式成了缩短供应链多阶响应周期的一个重要的研究领域。对比传统的物流模式,快速响应的供应链物流模式的主要改进点在制造商及其以下的节点企业的物流上。四种物流模式对于缩短供应链最终用户的响应周期有极大的意义和作用,它们是:基于制造商的直销模式、以批发商为改进点的零售支持型批发物流和区域零售支持型综合批发物流,以及以零售商为切入点的产销联盟的物流模式,并且它们各自不同的适用范围取决于供应链的运作特点和行业特征。     

Optimal estimation of a finite population mean under generalized random permutation models

Employing certain generalized random permutation models and a general class of linear estimators of a finite population mean, it is shown that many of the conventional estimators are “optimal” in the sense of minimum average mean square error. Simple proofs are provided by using a well-known theorem on UMV estimation. The results also cover certain simple response error situations.     

中国传统诗学的"异质性"概说

由于西学知识对传统知识谱系的全面替换,中国传统诗学已成为一种"异质"的知识.认识中国传统诗学的这种"异质性"对于中西两种异质的诗学如何在平等对话的基础上达到互补,具有重要的意义.基于这一总体性认识,文章从中西比较的角度对中国传统诗学的谱系结构、知识质态和知识言路作了具体而深入的分析,阐明了中国传统诗学的"异质性"特征.
