Moderate Deviations for Bayes Posteriors

Let ( X_k ) k be a sequence of i.i.d. random variables taking values in a set , and consider the problem of estimating the law of X₁ in a Bayesian framework. We prove, under mild conditions on the prior, that the sequence of posterior distributions satisfies a moderate deviation principle.     

Precise large deviations for the difference of two sums of END random variables with heavy tails

Assume that there are two types of insurance contracts in an insurance company, and the ith related claims are denoted by {X_ij, j ? 1}, i = 1, 2. In this article, the asymptotic behaviors of precise large deviations for non random difference ∑^n₁(t)_{j = 1}X_1j ? ∑^n₂(t)_{j = 1}X_2j and random difference ∑^N₁(t)_{j = 1}X_1j ? ∑^N₂(t)_{j = 1}X_2j are investigated, and under several assumptions, some corresponding asymptotic formulas are obtained.     

Hypothesis Testing in a Rayleigh Diffusion Model

Applying the large and moderate deviations for the log-likelihood ratio of the Rayleigh diffusion model, we give the negative regions in testing Rayleigh diffusion model and obtain the decay rates of the error probabilities.     

Elementary renewal theorems for widely dependent random variables with applications to precise large deviations

Abstract

On the basis of Wang and Cheng (J. Math. Anal. Appl. 384 (2011) 597–606), this paper further investigates elementary renewal theorems for counting processes generated by random walks with widely orthant dependent increments. The obtained results improve the corresponding ones of the above-mentioned paper mainly in the sense of weakening the moment conditions on the positive parts of the increments. Meanwhile, a revised version of strong law of large numbers for random walks with widely orthant dependent increments is established, which improves Theorem 1.4 of Wang and Cheng (2011 Wang, Y., and D. Cheng. 2011. Basic renewal theorems for a random walk with widely dependent increments and their applications. Journal of Mathematical Analysis and Applications 384 (2):597–606. doi:10.1016/j.jmaa.2011.06.010.[Crossref], [Web of Science ®] , [Google Scholar]) by enlarging the regions of dominating coefficients. Finally, by using the above results, some precise large deviation results for a nonstandard renewal risk model are established, in which the innovations are widely orthant dependent random variables with common heavy tails, and the inter-arrival times are also widely orthant dependent.     

Precise large deviations for φ-mixing and UND random variables with long-tailed distributions

In this paper, we investigate the precise large deviations for sums of φ-mixing and UND random variables with long-tailed distributions. The asymptotic relations for non random sum and random sum of random variables with long-tailed distributions are obtained.     

高校教学秘书的心理失范及其调适策略

高校教学秘书存在的心理失范现象,主要表现为缺乏足够的职业动力、非智能因素相对缺失等。这些心理失范问题有着主观、客观和制度方面的原因。鉴于此,高校教学秘书心理失范的调适策略应建立在优化办公环境和改革现有教学管理体制的基础上,并在调适策略上帮助其正确认识自我的心理状态、及时培养广泛的兴趣爱好和加强职业素质的持续锻炼。     

中国原创网游的语言变异与英译

在中国原创网游在国际市场的影响力不断增长之际,原创网游的翻译却一直未能引起网游开发企业的足够重视,成为影响与制约这些原创网游的商业价值和文化内涵的不利因素。本文欲从语言变异入手,剖析和探究这种网络语言在语音、词汇、语义和句法四个方面的语言变异现象,提出语言变异的英译原则和策略,以期为中国原创网游的英译实践带来一些有益的启示。     

弘扬和培育民族精神与全面建设小康社会关系研究

民族精神是由民族认知、情感、意志、价值观和凝聚力五个要素组成的有机系统,它对全面小康社会建设发挥着精神动力、人心凝聚、方向保证、开拓创新的功能.但是,民族精神遭遇着来自经济全球化和市场经济的双重挑战而削弱了其功能.为此,我们应该通过寻求中华民族精神结构与小康社会结构的契合、实现民族精神的现代化转换、拓展民族精神的领域和功能这三大途径及其相应的机制,培育与时俱进的民族精神,进而为民族精神促进全面小康社会建设提供理论借鉴,最后总结了民族精神生成和发挥作用的一般规律.
