Evaluating the Problem Gambling Severity Index

A large, integrated survey data set provided by the Ontario Problem Gambling Centre was used to investigate psychometric properties of the Problem Gambling Severity Index (PGSI). This nine-item self-report instrument was designed to measure a single, problem gambling construct. Unlike its nearest competitor—the South Oaks Gambling Screen (SOGS)—the PGSI was designed specifically for use with a general population rather than in a clinical context. The present analyses demonstrated that the PGSI does assess a single, underlying, factor, but that this is complicated by different, multiple factor structures for respondents with differing levels of problem gambling severity. The PGSI also demonstrated small to moderate correlations with measures of gambling frequency and faulty cognitions. Overall, the PGSI presents a viable alternative to the SOGS for assessing degrees of problem gambling severity in a non-clinical context.

What the ‘housing problem’ shows about today’s China*

ABSTRACT

This paper presents, elaborates and contextualizes the results of a survey concerning the meaning of housing in Mainland China, mainly for young people, and the perception of the various dimensions of housing as a problem. It considers the material, political, economic, and cultural dimensions of this problem, and the contradictory expressions of the problem (e.g. housing as a measure of success and as an investment). It examines the relation of the housing problem to three sub-systems: state politics, market economy, and the ‘urbanized, at-home living style’. Finally, it considers the paradoxes of competing consumer rationalities and the consciousness of capital and markets in China.     

Some asymptotic results for the integrated empirical process with applications to statistical tests

The main purpose of this paper is to investigate the strong approximation of the integrated empirical process. More precisely, we obtain the exact rate of the approximations by a sequence of weighted Brownian bridges and a weighted Kiefer process. Our arguments are based in part on the Komlós et al. (1975 Komlós, J., Major, P., Tusnády, G. (1975). An approximation of partial sums of independent RV's and the sample DF. I. Z. Wahrscheinlichkeitstheorie und Verw. Gebiete 32:111–131.[Crossref], [Web of Science ®] , [Google Scholar])'s results. Applications include the two-sample testing procedures together with the change-point problems. We also consider the strong approximation of the integrated empirical process when the parameters are estimated. Finally, we study the behavior of the self-intersection local time of the partial-sum process representation of the integrated empirical process.     

Assessing the differential impacts of online,mixed, and offline gambling

The emergence of new behaviours associated with communication technologies has prompted questions about the evolution of gambling in the population. The development of online gambling gave rise to public health concerns back 20 years ago. Current knowledge indicates that online gamblers generally tend to show more psychosocial problems than offline gamblers. But those portraits tend to neglect the differences between pure and mixed online gamblers. The goal of this research is to assess if, and to what extent, online gambling generates more harmful impacts on the health and well-being in a sample of adult gamblers in Québec. The propensity score matching method was chosen to assess the variable prevalence of impacts on a sample of 810 regular gamblers recruited from an online panel. They were divided into sub-groups: pure online gamblers (n = 143), mixed online gamblers (n = 125), and a control group of offline gamblers (n = 542). The study has revealed that among online gamblers and their entourage, online gambling does, in fact, result in an extra burden of impacts in several aspects of their lives: work, relationships, mental/physical health, finances, quality of life, and problem gambling according to the Canadian Problem Gambling Index. Results also show that combined with offline gambling, online gambling significantly increases the burden of impacts in terms of both the number and intensity of impacts. This is the first empirical study using propensity score matching to asses the incremental impacts of online gambling by separating pure and mixed gamblers and to compare them to offline gamblers.     

巴基斯坦加入上海合作组织:必要性与问题

近年来,巴基斯坦一直强烈要求加入上海合作组织,其积极申请加入上海合作组织的行动是出于其战略考虑,以谋求自己在反恐和经济发展上的现实利益,并构成巴基斯坦安全战略的重要组成部分。巴基斯坦加入上海合作组织具备必要性和一些有利条件,但也存在一些问题和困难,目前看,实现这一目标还需时日。
