Estimation of a finite population total in two-stage and stratified sampling under superpopulation models

Optimal sampling strategies which minimise the expected mean square error for a linear design as well as model-design unbiased estimators for a finite population total for two-stage and stratified sampling are obtained under different superpopu1ation models     

Accelerated test system strength models based on Birnbaum–Saunders distribution: a complete Bayesian analysis and comparison

Several models for studies related to tensile strength of materials are proposed in the literature where the size or length component has been taken to be an important factor for studying the specimens’ failure behaviour. An important model, developed on the basis of cumulative damage approach, is the three-parameter extension of the Birnbaum–Saunders fatigue model that incorporates size of the specimen as an additional variable. This model is a strong competitor of the commonly used Weibull model and stands better than the traditional models, which do not incorporate the size effect. The paper considers two such cumulative damage models, checks their compatibility with a real dataset, compares them with some of the recent toolkits, and finally recommends a model, which appears an appropriate one. Throughout the study is Bayesian based on Markov chain Monte Carlo simulation.     

Promoting the Visibility of Educational Research through an Institutional Repository

Established in 1994 through the amalgamation of several teacher training colleges, The Hong Kong Institute of Education (HKIEd) is the major multidisciplinary teacher education provider in the Hong Kong SAR. Despite this, the Institute does not have a particularly high research profile when compared with its peer institutions in Hong Kong and around the world. Its research publishing achieves modest exposure and impact in international educational research literature. The Institute has a goal to attain the title of a “university of education” and has identified an improvement in its research output and profile as critical to achieving this. In this context the HKIEd Library embarked on the redevelopment of its institutional repository, changing its direction from being an archive of institutional publications to one which brought together and offered access to the sum total of published output of the Institute since its foundation, in a deliberate effort to promote Institute research. This paper explores the particular approach taken by the Library to the development of the institutional repository, how the repository contributes directly to and aligns with the research strategies of the Institute, and the impact the Repository has had so far on improving the profile of research at HKIEd.     

中国高等教育与经济发展的区域协调性

 本文应用因子分析法对我国分地区高等教育与经济发展水平的协调性进行了实证分析。利用31个省区市2006年横截面数据计算了各地高等教育与经济发展的因子得分,进行排序、等级差和相关性分析。研究表明：31个省区市中,高等教育与经济发展协调程度为好和较好的有12个,差和较差的有13个,协调程度一般的有6个,总体协调程度较差。在分析个案原因的基础上,提出高等教育发展规划要更多考虑地方经济发展状况和潜力;鼓励高等教育发展滞后地区的地方政府加大对高等教育投资,支持社会资本进入高等教育领域;适当控制发展过度地区的高等教育规模,并加大中央财政对西部欠发达地区的财政支持。     

中国城市化与生态环境协调发展预警系统研究

本文构建了城市化与生态环境协调发展预警指标体系,并对1991～2010年中国城市化与生态环境的协调度进行了测算及预测,根据协调度建立了预警系统,并对90年代以来中国城市化与生态环境的协调发展进行了分析。结果表明,2007年以来,中国的生态环境不断恶化,城市化与生态环境的协调度不断下降,保护生态环境成为城市化进程中的重要问题。

西部大开发论略

东、西部经济差距形成的原因有自然地理因素,也有社会政治因素,后者主要指国 家发展战略的影响、产业结构和所有制结构方面的不同和人员素质等软环境的差异。中国实 施西部大开发战略,既是为了实现振兴农业、缓解基础产业、扶持战略产业的经济目标,也 是为了实现能够体现社会主义本质特征的政治目标,又是能够扩大我国经济与军事战略纵深 ,突破反华围堵,争取长期主动的战略部署。西部开发成功的关键是注重人力资源的开发和 人力资本的积累,进行科技创新和制度创新,借新经济之风,鼓西部开发之帆;走传统开发 之路,只能是事倍功半。     

经学振荡式发展的原因及启示

我国古代的经学,由西汉今文经学到东汉古文经学,到魏晋“王学”,到南北朝隋唐疏注之学,到宋明义理之学,到乾嘉考据之学,经过了四次振荡式发展。造成经学振荡式发展的原因,主要有社会文化需求的阶段性变化、实现儒学社会价值与追求儒经学术品位的矛盾,以及经典文本特点（主要是文词的多义性和句义的可扩展性）这三点。经学振荡式发展规律告诉我们,二十一世纪的国学研究,必须贴近现实,面向社会,为大众服务。
