Efficient Markov chain Monte Carlo with incomplete multinomial data

We propose a block Gibbs sampling scheme for incomplete multinomial data. We show that the new approach facilitates maximal blocking, thereby reducing serial dependency and speeding up the convergence of the Gibbs sampler. We compare the efficiency of the new method with the standard, non-block Gibbs sampler via a number of numerical examples.     

Does the marriage market sex ratio affect parental sex selection? Evidence from the Chinese census

Recent increases in the (male/female) sex ratio at birth in eastern Asia are thought to be associated with a preference for sons and to result from parental sex selection. However, males are less likely to marry and to have offspring as the ratio increases, and that decreases the expected number of grandchildren. Using data from the 2000 Chinese census, we test whether the sex ratio in the marriage market has an effect on the gender of subsequent births and hence on the sex ratio of the birth cohort. The slow population growth caused by the Great Famine in the early 1960s and the quick recovery that followed produced major changes in the sex ratio for those of marriageable age two decades later. We estimate that an increase of 1 % in the number of marriageable males relative to females, the marriage market sex ratio, would decrease the probability of having a son by 0.02 percentage points. That implies that the Great Famine, which occurred around 1960, led to an increase in the early 1980s of 5.8 extra male births per 100 females.     

Strassen type limit points for moving averages of a wiener process

Let {W(s); 8 ≥ 0} be a standard Wiener process, and let β_N = (2a_N (log (N/a_N) + log log N)^-1/2, 0 < α_N ≤ N < ∞, where α_N↑ and α_N/N is a non-increasing function of N, and define γ_N(t) = β_N[W(n_N + ta_N) ? W(n_N)), 0 ≥ t ≥ 1, with n_N = N – a_N. Let K = {x ? C[0,1]: x is absolutely continuous, x(0) = 0 and }. We prove that, with probability one, the sequence of functions {γ_N(t), t ? [0,1]} is relatively compact in C[0,1] with respect to the sup norm ||·||, and its set of limit points is K. With a_N = N, our result reduces to Strassen's well-known theorem. Our method of proof follows Strassen's original, direct approach. The latter, however, contains an oversight which, in turn, renders his proof invalid. Strassen's theorem is true, of course, and his proof can also be rectified. We do this in a somewhat more general context than that of his original theorem. Applications to partial sums of independent identically distributed random variables are also considered.     

A Changing Nexus Between Unemployment and Suicide in Taiwan: Before and After Labor Welfare Improvement in the Late 1990s

The 2009 economic crisis in Greece had harsh implications on the Greek society. The crisis led to high and increasing unemployment rates, which previously found to relate to increases in suicide rates, health risking behaviors and increased risk of mental health problems. The public’s perceptions regarding the consequences of the crisis are crucial to their recovery. In order to get a comprehensive and thorough view of the public’s perceptions, which will allow to draw conclusions and recommendations for a possible effective intervention program, the current study assessed the perceptions of a representative sample of the Greek adult population (N = 3002) in three sampling waves: December 2011, March 2011 and November 2012. These assessments included questionnaires designed to evaluate perceptions of current quality of life, economic decline, coping with economic and occupational commitments, physical and psychological health, wellbeing, health related behaviors, attitudes towards emigration, sources of support and political and social trust. Findings showed significantly higher perceptions of financial uncertainty and difficulties coping with economic commitments. Participants generally rated their psychological health lower than their physical health. Trust ratings were also found to be generally low, especially for younger populations. Younger populations also showed a more willing attitude towards emigrating out of Greece, compared to older populations. Coping measurements revealed a strong possible tendency to go back to the traditional ties of confidence and trust in family and friends as sources of support. In light of the results, we recommend to build programs that see the family and the local community as a resources of resilience and coping.     

An exploratory study to conceptualize press engagement behavior with public relations practitioners

This study addresses how journalists respond to public relations (PR) practitioners in co-creating value for their audiences. The co-creation perspective is conceptualized by synthesizing extant literature from public relations and relationship marketing, including cultivation strategies in organization-public relationships studies, two-way symmetrical model in excellence theory, intereffication model, service-dominant (S-D) logic of co-creation in marketing, and customer engagement theories. Using long-interview technique with 18 journalists, the study investigates how journalists perceive media relations activities of PR practitioners from a value co-creation dimension. A new theoretical model titled press engagement behavior (PEB) with sub-dimensions in press participation behavior (PPB) and press citizenship behavior (PCB) is proposed. A thirty-item scale is proposed to guide future study on scale development and validation. The proposed new model can explain the context of journalist engagement, enriching the operational value of cultivation strategies in dyadic relationship settings.     

Evaluating the Effectiveness and Efficiency of Hong Kong Welfare Programmes in Reducing Child Poverty

This paper examines the effectiveness and efficiency of welfare programmes that are relevant to child poverty reduction in Hong Kong. We employ data from a cross‐sectional survey of a representative sample of families, conducted in 2015 through face‐to‐face interviews. Our results indicate that all four welfare programmes were inadequate in alleviating child poverty. This was either due to the deep poverty gap to be filled or high rates of exclusion error. Most programmes are also inefficient because of inclusion error. We conclude by suggesting some policy implications for the welfare programmes.     

‘Vietnam is my country land,China is my hometown’: Chinese communities in transition in the south of Vietnam

Studies of Southeast Asian Chinese are voluminous; yet, those about the Chinese in Vietnam are comparatively few. This article provides an updated account of the Chinese Vietnamese with focuses on the Chinese associations in the South of Vietnam and the shifting Chinese identity. Many have discussed the Chinese Vietnamese who fled Vietnam in the 1970s and 1980s, however, little is known about the plights of the Chinese inside Vietnam during those decades. This article elaborates on their situations in the post-unification decade in Ho Chi Minh City and the subsequent changes after the doi moi reforms in the 1990s. It will show how a liberalized economy and accommodative ethnic policies have resulted in a more proactive relationship between the Chinese minority and the Vietnamese society, which consequentially led to changes in the relationship between the Chinese in Vietnam and China.     

Moral Schemas in Articulation and Intuition: How Religious People Evaluate Human Reproductive Genetic Technologies

As new and more effective human reproductive genetic technologies (RGTs) rapidly develop, religious voices remain an important part of public discussion about the moral standing of such technologies. Here, we compare how individuals from different religious traditions evaluate disease RGTs (detecting genetic diseases in vitro) when compared to enhancement RGTs, allowing parents to select features of a child. Findings are gleaned from analysis of 270 interviews with individuals from 23 Christian, Muslim, and Jewish religious organizations, with supporting data from a national survey of more than 10,000 Americans. We find that respondents engage in clearly defined discursive moral reasoning to evaluate the propriety of disease RGTs while moral intuitions manifest themselves in responses to enhancement RGTs. We argue that schemas provide resources for moral discourses while also shaping moral intuitions expressed through emotions. Our results have implications for how religious people respond to new technologies when their institutional and denominational structures do not have readily discernable moral frameworks to guide responses.     

The struggle for hegemony: the emergence of a counter-public sphere in post-1997 Hong Kong

The present study examines the struggle for hegemony in the public sphere by two different systems, following Hong Kong’s handover to China in 1997. It has been postulated that the new media, particularly social media, has become an important public sphere for the citizens of Hong Kong to engage in an anti-hegemonic struggle against China’s discursive encroachment into Hong Kong since 1997. Given that the public platform provided by legacy media has been bought out or coopted by China, new media has begun to serve as a subaltern public sphere to enable resisting the hegemony imposed by China. This was analyzed through a survey conducted as part of this study, which showed that people who are young, read the Apple Daily, have high expectations of local autonomy, and a high regard for press freedom are prone to using social media to obtain their social and political information. This article analyzes the implications of the emergence of a counter-China hegemonic public sphere.
