The Robustness of Trend Stationarity: An Illustration with the Extended Nelson-Plosser Dataset

We re-evaluate Andreu and Spanos's findings in favour of trend stationarity by considering the extended Nelson-Plosser data set. This expanded (to 1988) data set includes a period of rather different behaviour compared with the original Nelson-Plosser data used by Andreou and Spanos. We find that Andreou and Spanos's models (with only minor adjustments) exhibit remarable stability over this extended period, and indicate that their conclusions are more robust than they have shown.     

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.     

中国雇员群体状况分析

随着社会经济的发展及人口老龄化程度的不断加深，劳动力状况作为影响经济增长的重要因素引起社会各界的关注。然而，基于劳动力就业身份的雇员群体的描述性分析非常少。因此，本文利用2012年中国劳动力态调查（CLDS）数据，详细描述了他们受雇条件、受雇情况、劳动收益、工作状况及劳动侵权状况、工作评价及工作价值观；同时，分析了不同性别、年龄层及不同地区雇员群体在上述方面存在的差异，并对这些差异进行了一定的讨论，希望对相关劳动政策的制定有所启发。     

浅析汉日[主题]和[主语]对照

关于[主题]和[主语]这两个词,对于日语学习者来说一点都不陌生。很多讲授者在回答这两个词的区分问题时,都会以「は」和「が」的区分作为分析的论点。「は」是表示主题,而「が」则表示主语。表面上看已经解决了关于主题和主语的区分,但实不则然。本文将从汉日互译的角度出发,基于「は」和「が」的基本含义之上,分析[主题]和[主语]的汉日对照。     

中西文化差异与理解的融合

中西方文化由于自然环境和传统思想的差异而呈现迥异的面貌，这两个不同的生长基点造成中西道德价值观、中西哲学思维方式、中西文学审美风格的差异。中西方人的社会行为和思维方式的差异源于中西文化差异。中西文化的互识、互敬、互补需要建立在真正相互理解的基础才能达到相互融合，这是全球文化构建的正确发展方向。     

中国农村少数民族与汉族居民住房实证分析

本文结合中国2000年人口普查家庭住房资料,采用定量指标体系,从数量(人均建筑面积)和质量(住房结构、建筑材料及配套设施),对我国农村的少数民族和汉族住房进行了对比分析.同时利用Logistic回归模型,从农村家庭户主的民族成分、受教育程度、家庭规模、居住的地域差异等方面进行了微观研究,探讨了影响住房差距的因素,并提出了相应政策建议.     

哈贝马斯和利奥塔现代性理论之比较

在哈贝马斯和利奥塔之间进行的关于现代性的争论颇具代表性,一个声称现代性是"一项未竟的事业",另一个则对元叙事表示质疑。哈贝马斯的"共识"理论和利奥塔的"差异"理论,表面上思维迥异,但实际上却包藏了雷同与巧合,具有差异性的同时也具有共通性。在深层次进行整合,寻找两者理论及政治倾向中蕴藏的共同点,利于剖析两者理论的合理与局限,使超越两者形成新的理论成为可能。     

Similar Faults Different Endings--A Comparison between the Origins of Tess’s and Hester’s Tragedy

Hester Prynne and Tess Durbeyfield were two eminent female figures in the world by Thomas Hardy and Nathaniel Hawthone.Although the two female leading characters were in different time and place,their tragic experiences were almost the same.However,they were separated in the end.From the comparison of their personalities and the social situation they involved in,we would try to explore the origins of their similarity and ending by this article with the aim of alerting the world.     

VARIANCE ESTIMATION IN NONPARAMETRIC MULTIPLE REGRESSION

ABSTRACT

We consider the variance estimation in a general nonparametric regression model with multiple covariates. We extend difference methods to the multivariate setting by introducing an algorithm that orders the design points in higher dimensions. We also consider an adaptive difference estimator which requires much less strict assumptions on the covariate design and can significantly reduce mean squared error for small sample sizes.     

企业营销道德水准测试的指标体系及评价方法研究

本文是“企业营销道德水准测试及评价系统”课题的前期研究成果。作者首先通过探测性调研确定了影响营销道德水准评价的企业营销行为,并在定量调研基础上将其归并为七个评价营销道德水准的维度,同样还根据定量调研的结果确定了企业营销道德水准的测评方法,为营销道德水准测试与评价系统的建立构筑了重要基础。
