产权制度变迁、公司治理结构与经济绩效--捷克与俄罗斯比较研究

俄罗斯和捷克在证券私有化方式上存在很大的不同。不同的私有化方式形成了不同的产权结构。俄罗斯形成了典型"内部人"控制,捷克则是作为外部人的投资基金分散持有企业的股份。不同的产权结构又导致不同的治理结构,进而对企业的绩效产生不同的影响。     

长株潭一体化呼唤文化融合

如何推进长株潭一体化,是关乎湖南发展、中部崛起的一个战略问题.近年来人们大多是从经济、行政等方面来思考对策,但很少有人关注文化在长株潭一体化中的地位和作用.     

论体育游戏对学生心理发展的作用

体育游戏在学校体育教学中具有十分重要的地位和作用.然而,它对学生心理发展的积极作用却尚未引起人们的高度重视.为此,本文就体育游戏对学生心理发展的积极作用进行了探索、研究,并从学生心理发展的角度,对体育游戏在体育教学中的运用提出了建议.     

城镇化与新农村建设协调发展的模式比较

城镇化与新农村建设在理论和整体上具有协调性,而在现实和局部上又具有不协调性。在实践中,推进城镇化与新农村建设协调发展的模式包括并进模式、扶植模式、复制模式和吞噬模式,不同模式具有鲜明的特点和适用取向。进一步推进城镇化与新农村建设的协调发展,需要中央与地方各司其职,充分发挥政府和农民的积极性,因地制宜地选择合理的推进模式,更加注重政策协同和政策工具的选择。     

区域文化产业创造力比较体系的构建研究——以中部六省为研究样本

在各地文化产业蓬勃发展的背景下,区域文化产业创造力是评价一地区文化产业发展状况和优劣势的重要方法。文章以中部六省为研究样本,采用因素综合法,以产业竞争力的决定因素为评价对象,遵循综合性、代表性、层次性的原则选取单项指标,间接实现对文化产业创造力的评价。在数据收集阶段,由于详细数据的无法实现,采用主因子分析法解决这一问题,运用贡献率分析选取主因子,最终通过主因子赋值排序实现对中部六省文化产业创造力的评价。     

Statistical Inference on Partially Linear Additive Models with Missing Response Variables and Error-prone Covariates

This paper considers statistical inference for the partially linear additive models, which are useful extensions of additive models and partially linear models. We focus on the case where some covariates are measured with additive errors, and the response variable is sometimes missing. We propose a profile least-squares estimator for the parametric component and show that the resulting estimator is asymptotically normal. To construct a confidence region for the parametric component, we also propose an empirical-likelihood-based statistic, which is shown to have a chi-squared distribution asymptotically. Furthermore, a simulation study is conducted to illustrate the performance of the proposed methods.     

General results of complete convergence and complete moment convergence for weighted sums of some class of random variables

ABSTRACT

In the article, the complete convergence and complete moment convergence for weighted sums of sequences of random variables satisfying a maximal Rosenthal type inequality are studied. As an application, the Marcinkiewicz–Zygmund type strong law of large numbers is obtained. Our partial results generalize and improve the corresponding ones of Shen (2013 Shen, A.T. (2013). On strong convergence for weighted sums of a class of random variables. Abstr. Appl. Anal.2013, Article ID 216236: 1–7. [Google Scholar]).     

Tail-Adaptive Location Rank Test for the Generalized Secant Hyperbolic Distribution

The generalized secant hyperbolic distribution (GSHD) was recently introduced as a modeling tool in data analysis. The GSHD is a unimodal distribution that is completely specified by location, scale, and shape parameters. It has also been shown elsewhere that the rank procedures of location are regular, robust, and asymptotically fully efficient. In this article, we study certain tail weight measures for the GSHD and introduce a tail-adaptive rank procedure of location based on those tail weight measures. We investigate the properties of the new adaptive rank procedure and compare it to some conventional estimators.
