In this paper, exact solution of Wilks' type-B integral equation has been obtained in its most general form as a series of weighted gamma distributions. This general result then gives the distributions of many test statistics in multivariate analysis. In particular the distributions of Wilks' Λ, the sphericity test criterion, and Bartlett's test statistic, are derived in easily computable form. 相似文献

Although it has been determined that gambling is a popular activity amongst the young, there seems to be a lack of studies examining developmental differences in children's gambling behavior. This study examines developmental differences in children's blackjack gambling behavior. One hundred and four students (51 males; 53 females) from grades 4, 6, and 8 completed a questionnaire examining their gambling behavior in general and individually played a computerized blackjack game with the following data being recorded: percentage of accuracy, amounts of money bet, gross winnings, percentage of wins, number of hands played, and end balance. Findings revealed few developmental differences in prevalence and frequency of gambling behavior and performance on a blackjack task. Males were found to wager greater amounts of money and have larger gross winnings than females on the blackjack task. Furthermore, males were more likely to view gambling as involving both large amounts of skill and luck, thus suggesting an illusion of control for gambling activities. The results are discussed from a cognitive developmental perspective.This research was partially supported by a grant from the McGill University Social Science Computer Committee.

In a classical gambler's ruin problem, the distribution of the number of games lost till ruin is considered, which we call the lost game distribution (LGD). Some applications of LGD in the theory of queues, in the theory of epidemic and in certain clustering and branching models are mentioned. The maximum likelihood estimation of LGD in the framework of modified power series distribution (MPSD), introduced by the author (1974), is studied. The variance and bias of the MLE are given and the actual mean of the MLE is obtained by discussing the negative moments of the MPSD in general. The minimum variance unbiased estimator of θk (k≥1) is obtained employing the technique developed by the author (1977) for the class of MPSD. 相似文献

This article examines representations of lesbian nonsexuality in the film The Kids Are All Right and in responses to the film by feminist and queer scholars. In some moments, the film offers a limited endorsement of lesbian nonsexuality, placing pressure on the category lesbian to include nonsexuality and asexuality. However, in their responses to the film, many feminist and queer scholars rejected nonsexuality as an aspect of lesbian experience, placing pressure on the category lesbian to exclude nonsexual and asexual women. Asexual activism challenges scholars to question their sex-normative commitments and to keep the category lesbian open and flexible. 相似文献

Adolescent problem gambling is acknowledged as a public health concern. To better understand adolescent gambling and problem gambling behaviour, the present study investigated the relationships between psychological correlates of gambling frequency and problem gambling using an extended theory of planned behaviour (TPB; i.e. intentions, attitudes, subjective norms, perceptions of behavioural control) that includes negative anticipated emotions as a factor associated with gambling intentions. Four hundred and nineteen high school students were surveyed in the Montreal (Canada) region. The findings generally support the applicability of an extended TPB model for explaining gambling behaviour frequency and gambling problems among adolescents. The results reveal that negative anticipated emotions, attitudes and perceptions of behavioural control influence gambling intentions. The results further reveal that intentions and attitudes have a direct relationship with gambling frequency, while intentions and perceptions of behavioural control are directly related to problem gambling behaviours. These findings suggest that adolescent problem gambling prevention and intervention efforts should consider targeting negative anticipated emotions and other TPB components in order to postpone initiation to gambling (a risk factor for problem gambling) and to promote gambling decision-making. 相似文献

Abstract This study examined the relationship between anxiety, social stress, and gambling behaviour among 1,044 high school students in grades 7 to 11. Adolescents completed questionnaires concerning their state, trait, and generalised anxiety, social stress, and gambling behaviour. Results reveal that adolescent probable pathological gamblers report more state anxiety, trait anxiety, and higher levels of social stress compared to non‐gamblers, social gamblers, and gamblers at‐risk for serious problems. Gamblers with high state and trait anxiety engaged in more severe gambling behaviours, greater substance abuse, reported different reasons for gambling, and endorsed more dissociation items. The results provide additional support for Jacobs’ (1986) General Theory of Addictions. The implications for treatment and prevention programs are discussed. 相似文献

Both suicide and problem gambling among youth are two growing areas of public health concern, though studies have yet to characterise the relationship between these issues. Youth report higher prevalence rates of problem gambling than adults, but no studies to date have investigated whether they are likewise prone to higher risks of gambling‐related suicidality. This article explores the relationship of depression, suicidality, and problem gambling in youth in three studies of middle and high‐school students (total N = 3,941; males n = 1,937, females n = 2,004) conducted in 1996, 2000, and 2001 in Quebec and Ontario. All studies reported significantly higher rates of suicidality among problem and pathological gamblers as compared to non‐gamblers and social gamblers, irrespective of gender, grade, or level of depression. The implications for future investigations are discussed. 相似文献

We examine the impact of culture on the work behaviour of second‐generation immigrant women in Canada. We contribute to the literature by analysing the role of intermarriage in intergenerational transmission of culture and its effect on labour market outcomes. Using female labour force participation and total fertility rates in the country of ancestry as cultural proxies, we find that culture affects the female labour supply. Cultural proxies are significant in explaining number of hours worked by second‐generation women with immigrant parents. The impact of culture is significantly larger for women with immigrant parents who share the same ethnic background than for those with intermarried parents. The weaker effect of culture for women raised in intermarried families stresses the importance of intermarriage in assimilation process. Our findings imply that government policies targeting women's labour supply may have differential effects on the labour market behaviour of immigrant women of different ancestries.
Policy Implications
- The result that culture has statistically significant impact on second‐generation immigrant women's labour supply has policy implications in terms of the government programmes and benefits that target the labour supply of women and immigration policies in general.
- Our findings imply that government policies targeting women's labour supply may have differential influence on the labour market behaviour of second‐generation immigrant women of different ancestries.
