The Influence of Religiosity on Gambling Participation

Gambling is now a popular legal activity among people around the world. Despite numerous studies on individuals’ gambling behavior, few researchers examine the influence of religiosity on gambling participation. This study investigated the effect of religiosity, measured in terms of frequency of religious participation and importance of faith, on gambling participation across four different types of games: casino, track, lottery, and bingo. Using data collected by the National Gambling Impact Study Commission in 1999, the study found that there was indeed a significant difference in the frequency of religious participation between gamblers and non-gamblers. Moreover, it seemed like the more types of games one played, the lower was their frequency of religious participation. The importance of faith, however, did not seem to have a significant impact on gambling participation. The implications of these findings to businesses and public policy makers were discussed.     

Generalized Supremum Tests for the Equality of Cause Specific Hazard Rates

In this paper we propose two new classes of asymptotically distribution-free Renyi-type tests for testing the equality of two risks in a competing risk model with possible censoring. This work extends the work of Aly, Kochar and McKeague [1994, Journal of American Statistical Association, 89, 994–999] and many of the existing tests for this problem belong to these newly proposed classes. The asymptotic properties of the proposed tests are investigated. Simulation studies are done to compare the performance with existing tests. A competing risks data set is analyzed to demonstrate the usefulness of the procedure.     

Validity of the Dictionary of Occupational Titles as applied to construction site workers in Hong Kong

This study was designed to examine the content validity of the Dictionary of Occupational Titles (D.O.T.) as applied to construction site workers in Hong Kong. The study was divided into the First Expert Panel Review, the Second Expert Panel Review and the Field Study. The results indicated that (i) 15 out of the 55 items of the D.O.T. were identified as insignificant job requirements, and 14 items other than those suggested by the D.O.T. were identified as significant job requirements by the First Expert Panel; (ii) criteria of 20 out of the 40 items of the job requirements as suggested by the D.O.T. were identified as different from the ones suggested by the Second Expert Panel; and (iii) criteria of 4 items were found to be different among the D.O.T., the Second Expert Panel and the Field Study. The results of this study substantiate the claim that the validity of the D.O.T. is questionable, and research on a larger scale should be implemented to further examine the validity of the D.O.T.     

Assessing readiness to work from a stages of change perspective: implications for return to work

The Lam Assessment on Stages of Employment Readiness (LASER) was developed to assess welfare recipients' employment readiness. The LASER consists of 14 items corresponding to Prochaska's stages of change model (Prochaska, DiClemente and Norcross, 1992). A sample of 149 welfare recipients from a work training program participated in the study. The Confirmatory Factor Analysis (CFA) supported the three factors structure corresponding to Prochaska's Pre-Contemplation, Contemplation, and Action stages. A cluster analysis classified the sample into three groups according to their LASER scores. A six months follow-up on employment outcomes showed that those who were in Pre-contemplation stage had the poorest employment outcome (25%), those who were in the Action stage had the best outcome (56%) and those in the Contemplation stage were in between (38%). Implications for work rehabilitation and treatment matching were discussed.     

Why do unemployed people avoid participation in training? An experiment for policy making

Despite active labour market policies being implemented to increase the skills and job opportunities of the unemployed, the number of people who do not participate in training and other services of job orientation remains high. By providing a model that studies the decision-making process of a potential participant, we hypothesise there is a behavioural motive behind it. An experiment is carried out to account for both the individual's preference and the social expectations of agents such as the government and her peers with respect to active occupational measures. Findings show that young unemployed individuals are significantly influenced by their peers when deciding whether to participate or not in a training programme. Particularly, negative expectations from the peers cause unemployed potential participants in a within- and between-subjects experiment to be, respectively, 33 and 42 percentage points less likely to take part in job training.     

Ethical leadership and employee knowledge sharing: Exploring dual-mediation paths

Drawing on social learning and self-determination theories, this study investigates the mediating effects of controlled motivation for knowledge sharing and moral identity in the relationship between ethical leadership and employee knowledge sharing. We conducted a field study with 337 full-time employees to test our hypotheses. Results supported the mediating effects of both controlled motivation and moral identity in accounting for the relationship between ethical leadership and employee knowledge sharing. Our study is among the first to examine whether and why ethical leadership predicts employee knowledge sharing. Theoretical and practical implications are discussed.     

The game chromatic index of some trees with maximum degree four and adjacent degree-four vertices

A (proper) total-k-coloring of a graph G is a mapping \(\phi : V (G) \cup E(G)\mapsto \{1, 2, \ldots , k\}\) such that any two adjacent or incident elements in \(V (G) \cup E(G)\) receive different colors. Let C(v) denote the set of the color of a vertex v and the colors of all incident edges of v. An adjacent vertex distinguishing total-k-coloring of G is a total-k-coloring of G such that for each edge \(uv\in E(G)\), \(C(u)\ne C(v)\). We denote the smallest value k in such a coloring of G by \(\chi ^{\prime \prime }_{a}(G)\). It is known that \(\chi _{a}^{\prime \prime }(G)\le \Delta (G)+3\) for any planar graph with \(\Delta (G)\ge 10\). In this paper, we consider the list version of this coloring and show that if G is a planar graph with \(\Delta (G)\ge 11\), then \({ ch}_{a}^{\prime \prime }(G)\le \Delta (G)+3\), where \({ ch}^{\prime \prime }_a(G)\) is the adjacent vertex distinguishing total choosability.     

The Management Skills of Russians: Do Work,Management, and Government Experiences Matter?

This study examines the impacts of different types of experience on management skills of working adults in Russia. The study is based on a sample of 527 MBA students, line and middle managers covering 32 regions in 13 different industries in Russia. This study proves that work experience, management experience, and government experience are significant factors in their technical, human, and conceptual skills. Human skills scores are significantly higher for all groups than group with no management experience. Score for human skills increased with years of government experience only, but not with working or management years of experience.     

Debt,precarity and gender: male and female temporary labour migrants in Singapore

As one of Asia’s key hubs for transient workers, Singapore’s migration regime creates particularly gendered streams of labour, especially among lower skilled occupations, as is apparent in two key sectors – domestic work and construction work. Drawing on surveys with Bangladeshi construction workers and Indonesian domestic workers based in Singapore, as well as in-depth interviews with each group, this paper examines gendered issues of temporary labour migration, precarity and risk, as they occur against a backdrop of migrant indebtedness. In this paper, we argue that migrant indebtedness occurs along a spectrum that ranges from less visible, or what we call ‘silently’ incurred forms of debt, through to more ‘resonant’ types of debt that are acquired upfront and thus more readily quantifiable. Using this spectrum of migrant indebtedness, we aim to complicate debates about debt-financed migration by underscoring the ways in which notions of debt and unfreedom can be imbricated with both constraints and opportunities for migrants’ agency.     

Dynamic Random Effects Models for Times Between Repeated Events

We consider recurrent event data when the duration or gap times between successive event occurrences are of intrinsic interest. Subject heterogeneity not attributed to observed covariates is usually handled by random effects which result in an exchangeable correlation structure for the gap times of a subject. Recently, efforts have been put into relaxing this restriction to allow non-exchangeable correlation. Here we consider dynamic models where random effects can vary stochastically over the gap times. We extend the traditional Gaussian variance components models and evaluate a previously proposed proportional hazards model through a simulation study and some examples. Besides, semiparametric estimation of the proportional hazards models is considered. Both models are easily used. The Gaussian models are easily interpreted in terms of the variance structure. On the other hand, the proportional hazards models would be more appropriate in the context of survival analysis, particularly in the interpretation of the regression parameters. They can be sensitive to the choice of model for random effects but not to the choice of the baseline hazard function.
