An approximation of logarithmic functions in the regression setting

We consider a method of moments approach for dealing with censoring at zero for data expressed in levels when researchers would like to take logarithms. A Box–Cox transformation is employed. We explore this approach in the context of linear regression where both dependent and independent variables are censored. We contrast this method to two others, (1) dropping records of data containing censored values and (2) assuming normality for censored observations and the residuals in the model. Across the methods considered, where researchers are interested primarily in the slope parameter, estimation bias is consistently reduced using the method of moments approach.     

GMM tests for the Katz family of distributions

Generalized method of moments (GMM) is used to develop tests for discriminating discrete distributions among the two-parameter family of Katz distributions. Relationships involving moments are exploited to obtain identifying and over-identifying restrictions. The asymptotic relative efficiencies of tests based on GMM are analyzed using the local power approach and the approximate Bahadur efficiency. The paper also gives results of Monte Carlo experiments designed to check the validity of the theoretical findings and to shed light on the small sample properties of the proposed tests. Extensions of the results to compound Poisson alternative hypotheses are discussed.     

苏北“三农”问题的现状分析与研究

从江苏省“两个率先”目标的高度,就江苏苏北地区的“三农”问题进行分析,指出能否解决苏北“三农”问题已是影响江苏实现“两个率先”目标的关键,进而提出了解决苏北“三农”问题应从转变观念、提高农民国民待遇、加强农村基础设施建设和加快农村经济结构调整,以及加快苏北城市化建设,促进农村劳动力转移和控制人口增长,开发苏北农村的人力资源着手。     

毛泽东"以民为本"思想新探

“以民为本”思想是毛泽东思想的重要组成部分,是中国共产党新民本观的核心内容;全心全意为人民群众谋福利、人民是国家主人、向人民负责、关心人民群众生活、艰苦奋斗、勤俭节约的思想,是构成毛泽东“以民为本”思想的主要方面。     

当前高校双语教学应正确处理好四大关系

笔者认为,要保证当前高校双语教学工作的顺利进行,应正确处理好如下四大关系:一是语言教学与教学语言的关系,弄清双语教学的目标与手段;二是工作必要性与可能性的关系,认识双语教学的意义与可行性;三是师资水平与学生素质的关系,明确双语教学教的基本条件与学的可接受性;四是原版教材与教学方法的关系,解决双语教学的工作成效与质量。文章着重就以上四大关系各自的基本内涵、相互关系以及具体要求进行了全面深入的阐述。     

邓小平理论科学体系逻辑结构的再认识

邓小平理论继承并发展了马克思主义 ,是我们党和国家建设社会主义的指导思想。邓小平理论围绕“什么是社会主义 ,怎样建设社会主义”这个主题展开 ,是内含完整的逻辑结构的科学体系。邓小平理论科学体系由核心理论、基础理论、应用理论和边缘理论四个层次构成有机的逻辑结构。准确地把握邓小平理论的逻辑结构是完整地把握邓小平理论体系的内在要求 ,对于坚持和发展邓小平理论 ,指导社会主义建设具有重要意义。     

新时期地方综合性大学提高教学质量的四个要素

中国入世以后 ,中国的高等教育由精英化教育阶段走向大众化教育阶段 ,这在教育领域内引发了一场新的、极为深刻的变革 ,对地方综合性大学来讲 ,将面临着生存与发展的竞争。地方综合性大学能否适应形势的需要 ,关键在于教学的质量能否为社会所公认 ,而影响教学质量的“重要因素”——教学观念、师资队伍、教材和教学过程能否适应形势的需要 ,是地方综合性大学要考虑的头等大事。     

Almost Consistent Estimation of Panel Probit Models with “Small” Fixed Effects

We propose four different GMM estimators that allow almost consistent estimation of the structural parameters of panel probit models with fixed effects for the case of small Tand large N. The moments used are derived for each period from a first order approximation of the mean of the dependent variable conditional on explanatory variables and on the fixed effect. The estimators differ w.r.t. the choice of instruments and whether they use trimming to reduce the bias or not. In a Monte Carlo study, we compare these estimators with pooled probit and conditional logit estimators for different data generating processes. The results show that the proposed estimators outperform these competitors in several situations.     

儒家“德性”智慧与企业家“道德形象”

“三戒”之说，“屏四恶”思想，“绝四毋”之说，“尊五美”思想和“三贵之道”是儒家“德性”智慧的结晶。现代企业“形象管理”理论认为，成功的企业管理是由管理者的内在道德素质和外在礼仪形象决定的。打造企业家的“道德形象”，实施“自我管理”，应当从儒家“德性”智慧中汲取丰富的文化资源。     

First Nations and community economic development: a case study

A training project in a northern Canadian community providedan opportunity to examine participatory planning approachesand the meaning of work in First Nations communities. Focusgroups conducted three years after the unsuccessful interventionof a community economic development (CED) project suggest thatcomplex factors such as lack of support from community leadersand rate of pay for workers determine whether CED is alwaysappropriate in northern, First Nations contexts.
