关于“云消费”基本特征的研究

当前我们已经进入一个全新的以消费者为核心的商业时代——“云消费”时代.“云消费”在技术层面上表现为三大基本特征,即体现云消费发展内涵和容量的“云内容”,代表云消费终端平台的“云终端”,反映云消费的交易形式和支付方式的“云支付”.本文对此进行了较全面的研究.     

城乡医疗救助制度的现状、主要问题与建设重点

城乡医疗救助制度通过对困难家庭成员的直接救助与资助参加社会医疗保险, 对缓解困难家庭医疗支出负担起到了积极作用。 城乡医疗救助制度目前主要存在的直接救助水平过低、 财政投入非制度化以及审批手续繁琐、 病种限制过严等问题, 可以从提高直接救助水平、 扩大救助病种目录、 借鉴相关社保制度、 开展多样化救助, 以及加强基层医疗卫生建设、 对城乡困难家庭成员开展健康教育与继续提高医疗保险的保障水平等方面重点加强建设, 另外也应重视城乡医疗救助的信息化建设。     

Does corporate social responsibility influence the corporate performance of the U.S. telecommunications industry?

This study uses a two-stage approach to explore the relationship between the operational performance of U.S. telecommunications companies and their implementation of corporate social responsibility (CSR). In the first stage, this study adopts the dynamic data envelopment analysis model to measure the efficiency of the telecommunications industry in the U.S. from 2004 to 2008. The empirical results show that the corporate efficiency of those companies that implemented CSR was higher than that of those companies that did not. In the second stage, the study adopts OLS and 2SLS to explore the influence of the execution level of CSR on performance. The results show that the Kinder, Lyndenberg, and Domini & Co (KLD) social ratings indexes are significantly and positively related to corporate performance. Finally, this study suggests ways in which corporate policy makers can enhance CSR in order to improve corporate performance in the U.S. telecommunications industry.     

Learning Objectives and Testing: An Analysis of Six Principles of Economics Textbooks,Using Bloom's Taxonomy

This study applies Bloom's Taxonomy of Educational Objectives to six principles of economics textboks and the accompanying instructor's manuals to determine whether the test banks provided are likely to measure the textbooks' stated objectives. The study finds significant discrepancies between the stated objectives of most textbooks and the instruments included in the instructor's manuals to measure student achievement.     

On the asymptotic normality of some unbiased estimates

Abstract

Let X _m(n) =(X _j , n, ..., X _{j m,n} ) be a subset of observations of a sample X_n = (X_1n X _2n ... , X _nn ). Here the X_jn 'S in Xn are not necessarily independent or identically distributed, and m(n) mayor may not tend to infinity as n tends to infinity. Suppose the joint density function h_n =h_n (x _m (n); θ) of the X _jn 's in Xm(n) is completely specified except the values of the parameters in the parameter vector θ = (θ1 θ2, ... , θ _k ), where θ belongs to a non-degenerate open subset H of the k-dimensional Euclidean space Rk and k?m(n).
