A strong law of large number for negatively dependent and non identical distributed random variables in the framework of sublinear expectation

Abstract

In this article, in the framework of sublinear expectation initiated by Peng, we derive a strong law of large numbers (SLLN) for negatively dependent and non identical distributed random variables. This result includes and extends some existing results. Furthermore, we give two examples of our result for applications.     

An Improved Procedure of Estimating the Finite Population Mean Using Auxiliary Information in the Presence of Random Non Response

This article deals with the problem of estimation of the finite population mean using auxiliary information in the presence of random non response. Three different situations where random non response occurs either in study variate, or in auxiliary variate, or in both the variates, have been discussed. The asymptotically optimum estimators (AOEs) for each strategy are also identified. Expressions of biases and mean squared errors of the proposed estimators have been derived up to the first degree of approximation. Proposed estimators have been compared with the usual unbiased estimator, ratio estimator, and product estimator in the presence of random non response. Empirical studies are also carried out to show the performance of the proposed estimators over other estimators.     

Non‐parametric Threshold Estimation for Models with Stochastic Diffusion Coefficient and Jumps

Abstract. We consider a stochastic process driven by diffusions and jumps. Given a discrete record of observations, we devise a technique for identifying the times when jumps larger than a suitably defined threshold occurred. This allows us to determine a consistent non‐parametric estimator of the integrated volatility when the infinite activity jump component is Lévy. Jump size estimation and central limit results are proved in the case of finite activity jumps. Some simulations illustrate the applicability of the methodology in finite samples and its superiority on the multipower variations especially when it is not possible to use high frequency data.     

后现代文化观

后现代文化作为后工业社会人类拥有的一种生存状态、精神样式和美学实践,其目的、性质、对象、形式、内容、功能和价值都发生“哥白尼式”变化。一种健全的、非祛魅的、更多尊严和更多自主性的文化将是非异化的、人道的、自由的、多元的、反本质主义的、非决定论的多种文化形式的混合体。特别是第四世界文化将日益超越政治、国家、阶级、种族、意识形态和宗教信仰,真正实现自在和自为的统一;构建高质量的人文生态,塑造完整人性。     

英语习语中的非言语交际表达

从跨文化交际的角度对英语习语中的非言语交际行为及其特征进行探讨研究,认为英语习语在非言语交际中具有民族性和修辞性的特征,通过身体动作、面部表情、颜色、服装容饰等非言语行为的表达,强调和加强了言语内容,使得习语更加形象、生动、传神。     

不公平有几何？——中国城市居民收入分配公平感的测量

文章首先通过批判性地介绍几种已有的公平感测量方法,选取其中最为合适的一种在CGSS2005数据基础上测量中国城市居民的反身性公平感和非反身性公平感。其次,分别以性别、年龄、教育和单位体制变量分组,从多方面呈现了两种公平感在中国的现状。最后,作者通过使用对总体样本进行随机性拆分得到的两个样本对此测量方法的信度进行了验证。     

理论刑法向经验刑法的迈进——刑事和解视野下被害人地位的补足

在“国家-犯罪人”二元模式下,刑事和解提供提升和补足被害人地位的契机,被害人也应从幕后走向台前。刑事和解不应局限于侵犯个人法益的犯罪,侵犯公共法益的犯罪也具有刑事和解的正当性和必要性。同时,树立赔偿的惩罚机能和赎罪性质对于正确看待“以钱买刑”具有重要意义。刑事和解对于刑法理论的最大贡献在于从经验中推动刑法的迈进,纯理论的思辨刑法必将成为历史,未来的刑法将是充满活力的经验刑法。由经验到规范,实践经验与刑法规范的互动牵引着刑法的发展。     

在系统思维导引下构建和谐社会

用系统观点对构建和谐社会作概念诠释。构建和谐社会,必须贯彻系统思维:以整体思维取代片断思维,以非线性思维取代线性思维,以动态思维取代静态思维,以开放思维取代封闭思维,把自组织与他组织结合起来。     

发展个体私营经济的思考

社会主义初级阶段论的提出与确立,社会主义市场经济论特别是所有制改革理论的形成与发展,为我国发展私营经济提供了可靠的理论依据,从实践标准看,发展个体私营经济符合“三个有利于”标准,能够增强国家的凝聚力。目前,要发展我国个体私营经济的关键是采取正确的政策取向,应促进个体私营企业数量上的发展和质量上的提高,调整产业政策促进个体私营企业生产经营水平的提高,还要加强对个体私营企业的各项行政法规管理
