Social Capital and Human Mortality: Explaining the Rural Paradox with County‐Level Mortality Data

The “rural paradox” refers to standardized mortality rates in rural areas that are unexpectedly low in view of well‐known economic and infrastructural disadvantages there. We explore this paradox by incorporating social capital, a promising explanatory factor that has seldom been incorporated into residential mortality research. We do so while being attentive to spatial dependence, a statistical problem often ignored in mortality research. Analyzing data for counties in the contiguous United States, we find that: (1) the rural paradox is confirmed with both metro‐nonmetro and rural‐urban continuum codes, (2) social capital significantly reduces the impacts of residence on mortality after controlling for race and ethnicity and socioeconomic covariates, (3) this attenuation is greater when a spatial perspective is imposed on the analysis, (4) social capital is negatively associated with mortality at the county level, and (5) spatial dependence is strongly in evidence. A spatial approach is necessary in county‐level analyses such as ours to yield unbiased estimates and optimal model fit.     

Quality of Life in Older Adults: Benefits from Caring Services in Hong Kong

Many older adults are in need of care. Therefore, older people would generally benefit from the use of caring services, notably including home care, residential care, nursing, and medical services. The contributory factors underlying caring services tend to be a caring perspective that aspires to sustain older peoples social relationships and real-life involvement. To gauge the benefits from various social and health services, the present study relies on a large-scale survey of 3000 older adults in Hong Kong, using quality of life as a criterion. Results showed that an older adult who had used (ordinary or enhanced) home care services for a longer time turned out to have appreciably more improvement in quality of life. Besides, those who joined an interest group more frequently were higher in quality of life, including the health domain. On the other hand, frequent use of medical and meal-to-home services were signals that reflected problems detrimental to the older users quality of life. Despite this, the quality of clinics or hospitals, as perceived by the older adult, was the most beneficial. As such, caring services that foster older adults interests, cater to their health care needs, and embody quality can have principal contribution to their users quality of life.     

On tests for sex preferences

This paper presents a critical evaluation of three widely used tests for sex preferences: sex ratio, parity progression ratio and ordinary least squares regression of birth interval. We show that under some appropriate conditions, the sex ratio is a valid test for sex preferences. The methods of parity progression ratio and OLS regression of birth interval fail to deal with right censoring and time varying covariates, which reduce the power of the tests. We suggest the use of hazard estimation to test for sex preferences. We demonstrate the differences among the tests by analyzing the retrospective fertility histories of the Chinese and the Malays in Malaysia. We find that unlike the two conventional methods, the hazard estimation gives clear and strong evidence of sex preferences among the Chinese in Malaysia.I am indebted to Gary Becker, James Heckman and Thomas Mroz for their many valuable comments and encouragement.

Rural migrant workers in urban China: living a marginalised life

The rural migrant worker population in China is attracting more and more attention because of its magnitude and potential economic and social impact on Chinese society. While literature abounds in describing the demographic trends and economic impacts of rural to urban migration, very few articles have been written about the psychosocial impacts of migration on the lives of rural migrant workers in urban China. Drawing on the concept of marginalisation, this article describes the nature and characteristics of marginalised living experienced by migrant workers. More importantly, it examines the underlying policy issues contributing to such marginalised living. It is argued that the Hukou system (household registration system), the process of decentralisation and the obscure role of trade unions have contributed to the experience of marginalisation of rural migrant workers in urban cities in China. Implications for policy changes are also discussed.     

Simultaneous prediction intervals for multiple comparisons with a standard

k normal populations having common variance are used to construct two-sided and one-sided simultaneous prediction intervals for the differences between the future means of independent random sample from each of these populations compared to a standard. These prediction intervals are particularly useful if one has sampled the performance of several products and wishes to simultaneously predict the differences between future sample mean performance of these products and a standard with a predetermined joint probability. Methods on sample size determination are also given. The procedures are illustrated with a numerical example. Received: February 25, 2000; revised version: February 6, 2001     

The protective function of meaning of life on life satisfaction among Chinese students in Australia and Hong Kong: a cross-cultural comparative study

OBJECTIVE: The authors compared the predictive effects of acculturative stressors and meaning of life on life satisfaction between Chinese students in Australia and in Hong Kong. PARTICIPANTS: In 2006, the researchers recruited 606 Chinese students studying abroad at the University of Melbourne in Australia and at 6 universities in Hong Kong. METHODS: Participants completed a questionnaire that included measures of acculturative stressors, meaning of life, life satisfaction, and demographic information. RESULTS: The Australian sample experienced a significantly higher level of acculturative stressors than did the Hong Kong sample, but life satisfaction did not differ significantly between the 2 samples. Meaning of life had a strong positive contribution and acculturative stressors had a negative contribution in predicting life satisfaction in both samples. Meaning of life partially mediated the relationship between acculturative stressors and life satisfaction in both samples. CONCLUSIONS: The authors discuss the theoretical and practical implications for Chinese students studying abroad.     

City Spaces and Human Relations in Hong Kong's Mass Transit Railway: From Circulation to Everyday Life

Subways have experienced a tremendous variety of development, securing their positions within cities and producing unique spaces whose characteristics have influenced human relations. This study focuses on the relationships between subways and the cities, spaces, and human relationships that surround them. It explores the connections between subways and the aforementioned elements (city, space, and human relations) to provide insight into how best to pursue improvements. The Hong Kong Mass Transit Railway's fame as a representational subway on a global scale makes it the ideal choice for a case study.     

Changes in the junket business in Macao after gaming liberalization

Before Macao's gaming liberalization, people from Macao and Hong Kong took the active lead as junket operators to entice high-betting gamblers from neighbouring places. With the People's Republic of China as the dominating source of visitors to Macao, there have been some changes in the junket business. The qualitative research interview was adopted due to the under-researched nature of the junket business. This study is based on the institutional theory to analyse human interactions and activities structured in terms of overt or implicit rules involved in the junket business in Macao. A review of the literature and interview findings indicates that the active role played by local people appears to have diminished. As junket activities like patron recruitment and gambling debt collection are primarily conducted in Mainland China, together with the business opportunities from gambling and junket operators' preference for working with ethnically homogeneous groups, the previous active role played by local people is gradually being replaced by the Mainland Chinese. The junket business in Macao has been under the increasing influence of the Mainland Chinese. Based upon this, Macao needs to consider how to better regulate these junket operators.     

Design of accelerated life test plans under progressive Type II interval censoring with random removals

This paper investigates the design of accelerated life test (ALT) plans under progressive Type II interval censoring with random removals. Units’ lifetimes are assumed to follow a Weibull distribution, and the number of random removals at each inspection is assumed to follow a binomial distribution. The optimal ALT plans, which minimize the asymptotic variance of an estimated quantile at use condition, are determined. The expected duration of the test and the expected number of inspections on each stress level are calculated. A numerical study is conducted to investigate the properties of the derived ALT plans under different parameter values. For illustration purpose, a numerical example is also given.
