A single-featured EWMA-X control chart for detecting shifts in process mean and standard deviation

The combined EWMA-X chart is a commonly used tool for monitoring both large and small process shifts. However, this chart requires calculating and monitoring two statistics along with two sets of control limits. Thus, this study develops a single-featured EWMA-X (called SFEWMA-X) control chart which has the ability to simultaneously monitor both large and small process shifts using only one set of statistic and control limits. The proposed SFEWMA-X chart is further extended to monitoring the shifts in process standard deviation. A set of simulated data are used to demonstrate the proposed chart's superior performance in terms of average run length compared with that of the traditional charts. The experimental examples also show that the SFEWMA-X chart is neater and easier to visually interpret than the original EWMA-X chart.     

差异性社会的伦理逻辑与包容性增长的实现

差异性社会理论体现了马克思主义哲学认识及改造社会方法的创新特质。差异性社会理论是解读包容性增长的基本分析语境,差异性社会应当是良性发展的和谐社会,其发展伦理在价值观念、效率伦理、公民伦理这些方面为包容性增长界定规范性维度。差异性社会的道德冲突化解是实现包容性增长的重要精神保障。     

Optimal non-diagonal-type estimators in linear regression under the prediction error sum of squares criterion

This article considers the notion of the non-diagonal-type estimator (NDTE) under the prediction error sum of squares (PRESS) criterion. First, the optimal NDTE in the PRESS sense is derived theoretically and applied to the cosmetics sales data. Second, we make a further study to extend the NDTE to the general case of the covariance matrix of the model and then give a Bayesian explanation for this extension. Third, two remarks concerned with some potential shortcomings of the NDTE are presented and an alternative solution is provided and illustrated by means of simulations.

口译是一种复杂的交际行为，是高强度的脑力活动。记忆能力是口译基本素质之一，与口译有着密切而复杂的关系，认知心理学的引入拓宽了记忆力研究的视野。本文分析了口译过程中记忆的认知心理与记忆三步骤在大脑中的反应，总结出有效提高记忆效果的方法论，从而提升口译质量。     

专利保护期滥用解析——以跨国公司在中国专利战问题为视角

在日益激烈的高科技竞争背景下,专利权滥用的认定演变为不断更新的全球问题.WTO-TRIPS协议对专利滥用并没有明确认定范围,不同国家的做法不尽相同,而我国的相关立法尚属空白.只有从专利保护期滥用争议在全球范围、国内内外资企业范围、历史范围和我国市场整体利益范围上的主要特点,以及滥用认定中懈怠原则的基本法理层面上,透视滥用专利战的产生与存在现象,我们才可以对全球专利战产生相对客观理性的认识态度.面对全球化的专利战,应当有序提高专利注册标准、合理借鉴西方懈怠制度.通过有组织的强化专利法及其滥用认定规范,才能对专利权人利益予以合法保护,进而维护我国在技术市场开放及技术进出口方面的整体利益.     

Uniform asymptotics for ruin probability of a two-dimensional dependent renewal risk model

ABSTRACT

In this paper we consider the tail behavior of a two-dimensional dependent renewal risk model with two dependent classes of insurance business, in which the claim sizes are governed by a common renewal counting process, and their inter-arrival times are dependent, identically distributed. For the case that the claim size distribution belongs to the intersection of long-tailed distribution class and dominant variation class, we obtain an asymptotic formula, which holds uniformly for all time in an infinite interval. Moreover, we point out that the formula still holds uniformly for all time in an infinite interval for widely dependent random variables (r.v.s) under some conditions.     

物理化学设计型实验的测量知识准备

物理化学是一门与其他学科交叉渗透的综合性强大学科.从训练学生综合分析解决实际问题的能力、培养创新意识等方面来看,物理化学实验很具有代表性.因此物理化学实验教学改革的方案也比较多,很多很好的设计型或者叫科研型方案被提出.然而开设该设计型实验课之前,学生需要对于传感器、测量、计算机等方面知识做些准备,文章就此提出一些想法和建议.

生态行政学:理论源流、分化及其困顿

由于生态环境的恶化,政府和公民迫切需要行动起来,以应对日益严峻的生存危机.在反思工业文明的过程中,具有后现代情境的生态主义为生态行政理论提供了实践理性的基础.生态政治的核心价值和现实偏向以及行政生态理论的历史发展,均催化着生态行政理论的萌芽.由于概念认定和价值趋向的差异,以及范式转换和治理领域悖论的存在,生态行政研究亦呈现出分化、多元化与发展的困顿.生态行政理论应在整体性与共生性的原则下着力提升治理系统的开放性和必要的多样性,以应对环境领域日益严峻的复杂性与不确定性.
