Spritzer DT Rohde LA Benzano DB Laranjeira RR Pinsky I Zaleski M Caetano R Tavares H 《Journal of gambling studies / co-sponsored by the National Council on Problem Gambling and Institute for the Study of Gambling and Commercial Gaming》2011,27(4):649-661
The objectives of the study are: (a) to provide the first prevalence estimates of pathological gambling among Brazilian adolescents
using an age-specific instrument in a nationally representative sample; (b) to investigate the extent to which adolescents
participate in gambling activities in a developing country; and (c) to correlate different levels of gambling behavior with
demographic variables. Multistage cluster sampling selected 3,007 individuals over 14 years of age from Brazilian household
population. A total of 661 participants were between 14 and 17 years old. The Lie/Bet Questionnaire and the DSM-IV-MR-J were
used for assessing problem and pathological gambling. 2.8% scored positive on the screening questionnaire, while 1.6% were
classified as problem and pathological gamblers. Factors associated with problem and pathological gambling were male sex,
not currently studying and considering religion as not important. Less than 4 months elapsed between the age of regular gambling
involvement and the first gambling problem. Prevalence rates were quite similar from recent studies which used nationally
representative samples. The association of problem and pathological gambling with male sex, school drop-out and low religiosity
supports the Problem Behavior Theory. The fast progression to problem gambling adds evidence that adolescents may be more
vulnerable to the effects of gambling. 相似文献

In a single index Poisson regression model with unknown link function, the index parameter can be root- n consistently estimated by the method of pseudo maximum likelihood. In this paper, we study, by simulation arguments, the practical validity of the asymptotic behaviour of the pseudo maximum likelihood index estimator and of some associated cross-validation bandwidths. A robust practical rule for implementing the pseudo maximum likelihood estimation method is suggested, which uses the bootstrap for estimating the variance of the index estimator and a variant of bagging for numerically stabilizing its variance. Our method gives reasonable results even for moderate sized samples; thus, it can be used for doing statistical inference in practical situations. The procedure is illustrated through a real data example. 相似文献

Recent research reveals that divorce negatively impacts children's welfare as a consequence of the reduction in monetary and time contributions of the non-custodial parent. After divorce, the variables that link the absent parent to the child are visitations, child support transfers, and direct expenditures the non-custodial parent makes on the child. In our framework parents constitute a bilateral exchange economy where the mother is endowed with control over visitations and the father has control over financial resources. We use data from National Longitudinal Study of the High School Class of 1972 (5th follow up) to estimate the parameters of the model. We then use the estimates to simulate the effects of alternative endowment levels (such as joint custody) on the proportion of time spent with the non-custodial parent and the ex post parental income distribution. The results indicate that an endowment of equal time for both parents, reducing time under the mother's control implies a reduction in the child support transfers from the father, and, therefore, a loss in the mother's consumption levels. However, a more equally shared time with the children also increases the father's direct expenditures on the child, with the effect of allowing the mother to spend less on child goods and partially compensate her consumption loss. 相似文献

This study sought to describe religiosity and denominational affiliation among the U.S. population living with HIV and to test whether either is associated with HIV-related sexual risk behaviors. A nationally representative sample of 1,421 people in care for HIV, 932 of whom reported recent sexual activity, was utilized. Religiosity was associated with fewer sexual partners and a lower likelihood of engaging in unprotected sex and in high-risk sex. Catholics were less likely to report unprotected sex than were other Christians, adherents of non-Christian religions, and those reporting no religious affiliation. Catholics were also less likely than other Christians to report high-risk sex and reported fewer sexual partners compared to those of non-Christian religions. We did not observe a difference between Catholics and Evangelicals in the three sexual behaviors investigated. Results suggest that religiosity and some religious teachings may promote safer sex among people with HIV. 相似文献

ABSTRACT This study aims to describe rehabilitation and resocialization methods we believe to be appropriate for application to female patients with schizophrenia, in a psychiatric unit with a predominantly older population. We briefly describe the unit and the interventions used as an example of the proposed rehabilitation and resocialization methods applied. The article provides an overview to guide accurate intervention, particularly in inpatient women, in different types of cognitive impairment under the broad category of schizophrenia. Our clinical approach includes a token economy approach, cognitive remediation therapy, and social skills training. The token economy intervention is particularly directed to patients that present with a high mental deterioration and/or debility. Cognitive remediation training is applicable to subjects with both cognitive and social dysfunction, but that do not possess signs of an organic cerebral illness or of substance abuse. Social skills training can be the third step to resocialization, training verbal and nonverbal communication competencies. 相似文献

One of the main challenges in the field of performance measurement and management in public organisations is about how to use and manage performance measures effectively. This study aims to examine the stages involved in the process of utilisation of performance measures, i.e. adoption and implementation, and to investigate the political, cultural and rational factors that affect this process. For this purpose, a theoretical model from the literature has been extended and tested by using the data gathered through a survey involving the managers of several departments of Italian regions and municipal districts. The final sample has included 201 usable observations. The data analysis has been conducted using structural equation modelling. A significant cause-and-effect relationship was found between the stages of adoption and implementation. Moreover, it was found that adoption is driven significantly by rational factors. Otherwise actual implementation is influenced by factors addressed both by political considerations, such as external interest groups and by rational evaluations such as resources. The effects of other rational and cultural factors on implementation stage are mediated by adoption. 相似文献

Local governments are increasingly entering into partnerships with the private sector in the “externalization” of public service delivery. While the financial and non-financial interests of the partners involved may appear to be in opposition and potentially un-reconcilable, this is not always the case, especially where governance arrangements exist to align and balance the requirements of financial and non-financial performance. Such arrangements are analysed here with reference to Estonia’s largest water company with mixed public-private ownership. It has a business-like management that facilitates a combination of good non-financial performance (quality and affordability) and considerable financial performance (profitability). 相似文献
