Integrations,identity and conflicts: A cross-border perspective on residential relocation of Hong Kong citizens to Mainland China

This paper aims to test if traditional literature on both internal residential mobility and international migration hold up in explaining the driving forces behind the home-moving behaviours of Hong Kong residents to the Chinese Mainland, under a mixture of economic integrations, past connections along with present structural and identity differences. The multi-dimensionality of this behaviour, in comparison to other forms of residential movements in the literature, is shown as there is no single attribute, albeit all necessary conditions, sufficient enough to encourage such movement on its own. Instead, the cross-border residence is primarily a middle-class, middle-aged phenomenon, due to one’s past connections with Mainland China throughout his/her life course and the possession of financial resources insufficient to afford larger living space in Hong Kong yet enough to benefit from the remarkable living cost advantages on the other side of the border. It provides some directions for studying similar forms of residential mobility in the era of globalization when the functions of national borders have become more obscure than before. Implications from this residential behaviour are then discussed.     

Gendered Analyses of Nutrient Deficiencies Among the Elderly

This paper examines the factors that are associated with nutrient intake status of the elderly. Our study places special attention on the roles of physical functions, mental health, and dietary knowledge on the risk of inadequate nutrition consumption (nutrition consumption deficiencies). Using a nationwide survey of the elderly in Taiwan, we conduct empirical analysis separately by gender. Our results suggest that improving the physical conditions of male elders, the mental health of female elders, and dietary knowledge can decrease the nutrient consumption deficiencies of the elderly.     

Female victimization and intimate partner violence after the May 12, 2008, Sichuan earthquake

This study investigates the impact of the earthquake that occurred on May 12, 2008 in Sichuan, China on stressed families already experiencing domestic violence. We hypothesized that cumulative postdisaster stress would increase marital aggression and that the well-being of victims would deteriorate following the quake. A total of 186 women were recruited for this study. Results show that all types of family violence, including psychological aggression and physical violence between partners, increased after the earthquake. We provided preliminary evidence that psychological aggression was significantly associated with the detrimental effects on victims' mental and physical functioning. The findings support the need for violence assessment among victims of earthquakes, and we recommend that violence prevention be considered as part of the intervention during such natural disasters.     

A pro-active and collaborative approach to reverse logistics—a case study

Reverse logistics is considered to be the key for re-manufacturing and sustainable development. It has gained increasing attention in the last decade and has been a new frontier of strategic management. One of the driving forces for firms to adopt the reverse logistics practice is cost saving from reverse logistics activities. Another motivation to put reverse logistics forward is probably due to environmental impacts on non-returnable materials. Reverse logistics, however, may require cooperation of more than one company and hence it is generally poorly managed due to self-interest of different companies. Therefore, a pro-active and collaborative approach to reverse logistics is demanded. This paper reports a case study of using returnable packaging materials between a manufacturer and an original equipment manufacturer (OEM) supplier. A cross-company team was established to pursue the goal of the reverse logistics project. Tangible and intangible benefits of reverse logistics from this case study are presented in this paper.

Heteroscedastic Regression Models and Applications to Off-line Quality Control

We discuss in the present paper the analysis of heteroscedastic regression models and their applications to off-line quality control problems. It is well known that the method of pseudo-likelihood is usually preferred to full maximum likelihood since estimators of the parameters in the regression function obtained are more robust to misspecification of the variance function. Despite its popularity, however, existing theoretical results are difficult to apply and are of limited use in many applications. Using more recent results in estimating equations, we obtain an efficient algorithm for computing the pseudo-likelihood estimator with desirable convergence properties and also derive simple, explicit and easy to apply asymptotic results. These results are used to look in detail at variance minimization in off-line quality control, yielding techniques of inferences for the optimized design parameter. In application of some existing approaches to off-line quality control, such as the dual response methodology, rigorous statistical inference techniques are scarce and difficult to obtain. An example of off-line quality control is presented to discuss the practical aspects involved in the application of the results obtained and to address issues such as data transformation, model building and the optimization of design parameters. The analysis shows very encouraging results, and is seen to be able to unveil some important information not found in previous analyses.     

Statistical inference for start-up demonstration tests with rejection of units upon observing d failures

In this paper, we consider the statistical inference for the success probability in the case of start-up demonstration tests in which rejection of units is possible when a pre-fixed number of failures is observed before the required number of consecutive successes are achieved for acceptance of the unit. Since the expected value of the stopping time is not a monotone function of the unknown parameter, the method of moments is not useful in this situation. Therefore, we discuss two estimation methods for the success probability: (1) the maximum likelihood estimation (MLE) via the expectation-maximization (EM) algorithm and (2) Bayesian estimation with a beta prior. We examine the small-sample properties of the MLE and Bayesian estimator. Finally, we present an example to illustrate the method of inference discussed here.
