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.     

Finite-sample refinement of GMM approach to nonlinear models under heteroskedasticity of unknown form

It is quite common to observe heteroskedasticity in real data, in particular, cross-sectional or micro data. Previous studies concentrate on improving the finite-sample properties of tests under heteroskedasticity of unknown forms in linear models. The advantage of a heteroskedasticity consistent covariance matrix estimator (HCCME)-type small-sample improvement for linear models does not carry over to the nonlinear model specifications since there is no obvious counterpart for the diagonal element of the projection matrix in linear models, which is crucial for implementing the finite-sample refinement. Within the framework of nonlinear models, we develop a straightforward approach by extending the applicability of HCCME-type corrections to the two-step GMM method. The Monte Carlo experiments show that the proposed method not only refines the testing procedure in terms of the error of rejection probability, but also improves the coefficient estimation based on the mean squared error (MSE) and the mean absolute error (MAE). The estimation of a constant elasticity of substitution (CES)-type production function is also provided to illustrate how to implement the proposed method empirically.     

Combatting voter ignorance: a vertical model of epistocratic voting

In light of recent political events, prominent scholars have argued that voters ignorant of the issues should be disqualified from taking part in decisions that have the potential to alter political landscapes. As convincing as this literature is in highlighting voter ignorance, it fails to differentiate between local, state, and federal elections and how levels of political knowledge are often scale-dependent. If the level of median voter ignorance is not uniform from one level of government to the next, then neither can the reforms proposed to combat it. In this article, I adapt Bell’s vertical model of democratic meritocracy to argue that the larger the election, the more complex the issues, the more explicit the epistocratic safeguards needed.     

Spatial variability of epibiotic assemblages on marina pontoons in Singapore

Berthing pontoons, one of the most ubiquitous structures in marinas, are known to provide recruitment substrate for a variety of marine biota but little has been reported on their capacity to support epibiotic organisms in tropical marinas, and even less is known about the factors that shape their distribution in such environments. We surveyed the epibiotic assemblages on the sides of pontoons in three Singapore marinas and examined the environmental conditions that influenced their distribution. A total of 94 taxa were recorded, with each marina hosting 43–65 taxa. Assemblages among marinas were highly distinct, and, key discriminants included components of biotic (alcyonarians, hexacorallians, bivalves, and annelids), as well as abiotic (sediment, bare area and shell fragments) origin. While the assemblage variation among marinas was influenced by local environmental conditions (e.g. water motion and sedimentation rate) and pontoon material, the variation in distribution within each marina was best explained by the distance of the pontoons from the marina’s entrance (epibiotic diversity and taxa richness were lower away from the marina entrance). Knowledge on the distribution of epibiotic assemblages on pontoons is essential to identify the factors that contribute to spatial variation and encourage the design and construction of ecologically-friendly marinas. Our findings suggest that improvements to pontoon design and layout would help to augment marina biodiversity, enhance the ecology of urbanised coasts, and mitigate development impacts.     

A comparison of the size of families of roman catholics and non-catholics in Great Britain

Abstract In a recent study of family size ideals in the D.S.A. it was found that in the 1960'S the mean ideal family size of Catholics was about half a child higher than the mean ideal size of non-Catholics. This note describes an analysis of similar data for married women in Great Britain, derived from an investigation undertaken in 1966 for the Population Investigation Committee. A difference in ideal family size, which was of the same order as the American difference, was found; and, in addition, the actual fertility of Catholics was compared with that of others.     

The Network Autocorrelation Model using Two-mode Data: Affiliation Exposure and Potential Bias in the Autocorrelation Parameter

The network autocorrelation model has been a workhorse for modeling network influences on individual behavior. The standard network approaches to mapping social influence using network measures, however, are limited to specifying an influence weight matrix (W) based on a single mode network. Additionally, it has been demonstrated that the estimate of the autocorrelation parameter ρ of the network effect tends to be negatively biased as the density in W matrix increases. The current study introduces a two-mode version of the network autocorrelation model. We then conduct simulations to examine conditions under which bias might exist. We show that the estimate for the affiliation autocorrelation parameter (ρ) tends to be negatively biased as density increases, as in the one-mode case. Inclusion of the diagonal of W, the count of the number of events participated in, as one of the variables in the regression model helps to attenuate such bias, however. We discuss the implications of these results.     

Workplace support, role overload, and job satisfaction of direct care workers in assisted living

This study aims to enhance our understanding of job satisfaction of direct care workers in assisted living facilities. Low job satisfaction is related to high turnover rates and lower quality of care in assisted living. We integrate two theories of job satisfaction to investigate relationships among workplace support, role overload, and job satisfaction. Data are from a survey of 984 direct care workers in 108 assisted living facilities. Results from multilevel hierarchical linear models (HLM) indicate that job satisfaction varies both within and among facilities. Job satisfaction is negatively associated with role overload, and it is positively associated with institutional support, supervisor instrumental and emotional support, and coworker emotional support. These workplace support measures and role overload are separately and independently associated with job satisfaction. Enhancing job satisfaction of assisted living direct care workers will likely require a multipronged approach that includes improving institutional, supervisor, and coworker support while simultaneously directly addressing role overload.     

What Factors Influence Marital Satisfaction? Differences Between First and Second Marriages

This study examined differences in marital satisfaction between first and second marriages and how additional factors can help explain satisfaction differences between the marriage types. Participants in first marriages reported higher levels of satisfaction than remarried individuals. Regression analyses demonstrated marriage type to be a moderator of satisfaction in second marriages; as education increased, satisfaction also increased. Length of marriage was found to significantly influence satisfaction in first marriages, but not second marriages. In both first and second marriages, participants currently in counseling reported lower satisfaction scores. The need to understand remarriages' distinct characteristics apart from first marriages is discussed.
