As low birth weight babies grow,can well-educated parents buffer this adverse factor? A research note

This research note combines two national Taiwanese data sets to investigate the relationships among low birth weight (LBW) babies, their parents' educational levels, and their future academic outcomes. We find that LBW is negatively correlated with the probability of such children attending college at age 18; however, when both parents are college or high school graduates, such negative effects may be partially offset. We also show that discrimination against daughters occurs, but only for daughters who were LBW babies. Moreover high parental education can buffer the LBW shock only among moderately LBW children (as compared with very LBW children) and full-term LBW children (as compared with preterm LBW children).     

Foot-and-Mouth Disease Entrance Assessment Model Through Air Passenger Violations

This article aims to construct a risk model for the prediction of foot-and-mouth disease (FMD) entrance caused by passengers who illegally carry meat products of cloven-hoofed animals through international airports into a country. The risk that meat contaminated with the FMD virus is formulated as the probabilities of FMD factor events (the prevalence of FMD), the commodity factor event (the transportation, storage, and distribution (TSD) factor event), and the passenger event. Data used for analysis were records of illegal meat product carriers from areas A and B intercepted at an international airport in Taiwan. A risk model was proposed to simulate the probability distributions in disease prevalence, probability of FMD virus existing in the meat products after meat processing, and estimation of survival of virus and time period for TSD. The probability of the passenger event was hypothesized with the odds of intercepted passengers and estimated via logistic regression. The results showed that the odds of passengers being intercepted by beagles were higher than those intercepted by Customs. By conducting Monte Carlo simulations, the probability of FMD virus risk caused by FMD factors from area A was 149 times lower than that from area B. The probability of FMD virus risk caused by the passenger event from area A was four times lower than the corresponding probability from area B. The model provides a contribution to FMD prevention and can be a reference for developing models of other diseases.     

简析黑格尔的伦理有机体思想

黑格尔没有一本伦理学专著,他常常把伦理和伦理学都称为伦理,有时又把道德学说也叫做伦理学,这就增加了研究其伦理思想的难度。实际上,黑格尔关于伦理的思想是前后一贯的。在他那里,伦理学是客观伦理、主观伦理和绝对伦理构成的“一个伦理有机体”。黑格尔的伦理学决定了他在西方伦理史上的重要地位。     

Benevolence-dominant,authoritarianism-dominant,and classical paternalistic leadership: Testing their relationships with subordinate performance

We propose a new typology of paternalistic leadership styles based on how leaders demonstrate authoritarianism and benevolence, the two essential components of this type of leadership. Benevolence-dominant paternalistic leadership refers to leaders' sole dependence on the use of benevolence without their strong assertion of authority, whereas authoritarianism-dominant paternalistic leadership is based mainly on authoritarianism itself; classical paternalistic leadership, which best fits early observations of paternalistic leaders, refers to the salient combination of both leadership components. We used two distinct samples and methods to test this typology and the association with subordinate performance. Across the two studies, a field investigation with Taiwanese military supervisor-subordinate dyads and a hypothetical scenario experiment with U.S. working adults, we found a positive relationship between classical paternalistic leadership and subordinate performance as strong as that between benevolence-dominant paternalistic leadership and performance. Our findings echo the phenomenon that paternalistic leaders tend to combine benevolence with authoritarianism to affect subordinate performance.     

The roles of human capital and social capital in the economic integration of new arrivals from Mainland China to Hong Kong

Although it has been hypothesized in the literature that both human capital and social capital are important for the economic performance of new immigrants, few studies have examined these relationships empirically, especially in understudied populations such as Chinese populations. This study simultaneously examines the roles of human capital and social capital in the economic integration of new arrivals from Mainland China to Hong Kong, using a random sample of immigrants. In the early stage of immigration (less than 6 months after arrival), we find little support for the presumed positive effects of both human capital and social capital on employment status among new arrivals in Hong Kong. Follow-up studies are underway to investigate the dynamic relationship between social capital and economic integration in this group of new arrivals, and whether social capital, especially friendship networks, plays a more important role in the economic integration of new immigrants 1 or 2 years after arrival.     

Public Attitudes towards Income Redistribution: Evidence from Hong Kong

The drivers of public support for redistributive policy have stimulated academic debate around the world. The majority of studies use cross‐country surveys conducted in the Organisation for Economic Co‐operation and Development countries to contribute to the debate on whether self‐interest or social values have more influence on public attitudes towards redistribution. Drawing on a phone survey conducted in 2013, this study advances the discussion by investigating public attitudes towards redistribution and social policy changes against the backdrop of buoyant government revenues in Hong Kong. The Hong Kong welfare model, best seen as a parallel to the liberal welfare state, is selective and residual. Contrary to the usual assumption, the social values hypothesis, viewing poverty as societal problems instead of individual reasons, has been supported in the Hong Kong context. It lends support to greater redistribution in a residual welfare state. The policy implications of the findings are also discussed.     

Superimpose Material Deprivation Study on Poverty Old Age People in Hong Kong Study

Due to a range of shortcomings of income-based measures of poverty in older people, an alternative approach is proposed to counteract those shortcomings. Hong Kong index of material deprivation aims to identify a consensus-based list of goods and services that are necessities in society and to establish that these goods and services are not available due to their lack of affordability. This paper reports on the validation of Hong Kong index of material deprivation based on an approach proposed by Townsend (Poverty in the United Kingdom, Penguin Books, London, 1979) in Hong Kong. Through a survey of 2339 older Chinese people aged 65 and older, we found that a broad consensus regarding the necessities in their daily lives exists and Hong Kong index of material deprivation is a reliable and valid measure of poverty because its reliability and validity is good and acceptable. Finally, we have shown that the overlap between the poor in terms of income and the deprived is moderate and the profiles of those who are core poor (both poor in terms of income and the deprived) are more similar to those who are deprived than those who are poor in terms of income. Hong Kong index of material deprivation index has been developed, which offers a supplementary measure of poverty other than income poor and provides future avenues for improved understandings of poverty in old age.
