Linear Models in a general parametric form

The linear model Y - N(Xb, σ²∑) with a restriction R'b = M'u + c is considered, where X, R, M, ∑ and c are known. Explicit formulae are obtained for the best linear unbiased estimator of K'b, for the F-test of the hypothesis K'b = W'v + a, and for the simultaneous confidence intervals of the parameters K′_i b' s, where K = [K₁,K₂,…K_s], w, and a are known, none of the matrices X, ∑, R, M, K, and W is required to have full ranks, and the design X can be one - or multi-way,complete or incomplete, balanced or not balanced, connected or disconnected.     

Social Bookmarking–Repository–Networking: Possibilities for Support of Teaching and Learning in Higher Education

Abstract

Social bookmarking, repositories, networking, and other Web 2.0 technologies have the capacity to engage enormous numbers of ordinary people in networking, sharing, and working with digital resources. The Faculty of Education at The University of Hong Kong has been pioneering new educational applications. Through grants from the University we have developed a social bookmarking and repository system based on Web 2.0 ideas. RISAL—Repository of Interactive Social Assets for Learning has an unrealized potential to support teaching and learning at the University level. It is designed to facilitate and encourage sharing and collaboration of teachers and students with similar interests or learning foci across levels and programs. This form of learning support builds on and encourages the Web 2.0 culture of social networking and contribution of the individual to the community. In addition, the system is designed to incorporate compliance with Hong Kong's Copyright Ordinance (Creative Commons). The authors discuss the RISAL and describe its features and benefits that this system can offer to teaching and learning.     

Smoothing Spline Estimation for Partially Linear Single-index Models

In this article, the partially linear single-index models are discussed based on smoothing spline and average derivative estimation method. This proposed technique consists of two stages: one is to estimate the vector parameter in the linear part using the smoothing cubic spline method, simultaneously, obtaining the estimator of unknown single-index function; the other is to estimate the single-index coefficients in the single-index part by the using average derivative estimator procedure. Some simulated and real examples are presented to illustrate the performance of this method.     

The Emergence of a Community-based Social Assistance Programme in Urban China

To many people, the problem of poverty in China was confined mainly to the rural areas, and the situation of urban poverty was regarded as insignificant. Yet in fact, market-orientated economic reforms have created an urban underclass, made up of poorly paid state workers, the unemployed, and migrants from the countryside. In attempting to respond to the mounting needs of the urban poor, the Chinese government has introduced a means-tested social assistance programme in the cities since the mid-1990s. This paper describes the basic philosophy, structure and operation of this programme, and provides a general assessment of its functions and shortcomings.     

Producing and reconstructing knowledge on China in Singapore: perspectives from the academics and mass media

In Singapore, intellectuals, especially those in media and education, are considered as the driving force of formatting public opinion over the social imagination of China and Chineseness. This article, largely based on oral histories of some Singaporean scholars and media professionals and memoirs of related figures, analyzes the choice and acquisition of their knowledge on China. Through the analysis and comparison of their construction of knowledge on China, this article also discusses the accuracy of their understanding of China and how such understandings were formed along with their personal experiences from domestic socialization, education, and professional accumulation. The authors consequently map out the process of how public intellectuals from mass media and academia transform their knowledge imagination of China into the professional opinions that help to reconstruct and shift Singaporean’s impression and understandings of China.     

四十年来香港公共运输的发展与挑战

交通对经济发展和社会生活甚为重要.与上海一样香港公共交通也发展了百年之久.香港1880年开始过海渡轮服务,山顶缆车在1888年运营,有轨电车在1904年启用.香港的运输署也已成立40周年.     

Exploring Research Data Hosting at the HKUST Institutional Repository

Abstract

The profusion of data created by modern research has brought about increasing discussion on the practice of data management and the development of such infrastructure. Many universities and libraries are exploring how to address this issue using institutional repositories, the Hong Kong University of Science and Technology (HKUST) Library being one of them. As part of the exploration, the author conducted a case study of datasets at major institutional repositories. This paper visits the issues relating to data archiving, reports common practices of data treatment at institutional repositories, and presents a list of recommendations for experimenting data archiving at the HKUST Institutional Repository.
