Research and theory regarding the social facilitation effect generates the expectation that the presence of other gamblers (or co-actors) in a gaming venue is likely to intensify individual gambling behavior and magnify losses. Fifty male and 66 female participants (116 total) played a computer-simulated electronic gaming machine with a fixed winning sequence, followed by an indefinite losing sequence. Measures of the intensity of gambling behavior included the final payout (a direct measure of losses), average bet-size, number of trials played, and the speed of play. Some participants received false feedback from the computer designed to suggest that other gamers in adjacent rooms were playing and sometimes winning at the same game. Persons who received both sight and sound information, including winning bells and instant messages regarding the wins of other (fake) players, placed more bets and lost more money compared to the other conditions with less information.  相似文献

The Four Es is a 40-item scale measuring psychological risk for the development of problem gambling behavior. One-year follow-up interviews (n = 395) from a previously reported phone survey in Queensland, Australia (n = 2,577) (Rockloff & Dyer, 2006) tested the ability of the Four Es instrument to prospectively identify persons who would later develop gambling problems. Two groups of participants were selected for the 1-year follow-up interviews, including (1) persons who had gambling problems, high-risk alcohol abuse problems, and/or substance abuse problems (abuse group); and (2) a random selection of other persons from the original survey (random group). The results indicated that the “Excess” trait, which measures impulsive behavior, was predictive of relative increases in gambling problems for both groups over the 1-year period. Additionally, the Four Es questionnaire showed good psychometric properties in the surveys, with a test-retest reliability of r = .70 and a Cronbach’s alpha reliability of α = .90 and .92 in the original and follow-up interviews, respectively.  相似文献

Communities across the nation have become increasingly concerned about inhalant use and use of harmful legal products among youth because of increasing prevalence rates and deleterious health consequences from abusing these products. The increasing concern of communities about inhaling and ingesting legal products has been coupled with increasing awareness and concern about ability of youth to access and abuse a variety of other legal retail products. There are few examples of scientifically designed community prevention projects that seek to reduce youth abuse of such legal products. This article describes a community prevention trial that is designed to reduce sales of inhalants and other harmful legal products to youth and demonstrates how the retailer component of the trial can be rigorously evaluated. It also shows how data from youth purchase attempts can complement survey data from retailers.  相似文献

The relevance of women in contributing to inclusive growth and consequently economic development in Nigeria cannot be overemphasized. Women play important social, economic and productive roles in any economy. Maternal mortality rate refers to the annual number of deaths of women from pregnancy-related causes per 100,000 live births, and Nigeria’s rate is still relatively high at about 630 when compared with the figures of the developed countries. For inclusive growth to be achieved in Nigeria, women should not be neglected and marginalized so they can contribute their quota to the growth of the country, but maternal mortality rate needs to be reduced because it is only the living that can make contributions to growth. Thus, this study examined the long run effect of gender inequality, maternal mortality and inclusive growth in Nigeria using time series data spanning from 1985 to 2017, and employed the ARDL econometric technique. The results showed that gender inequality and maternal mortality have negative impacts on inclusive growth in Nigeria. Therefore, the study recommends that women should be properly taken care of during pregnancy so that the maternal mortality rate can be reduced and hence they will be able to make meaningful contributions to the growth of the Nigerian economy.

Noninferiority trials intend to show that a new treatment is ‘not worse'' than a standard-of-care active control and can be used as an alternative when it is likely to cause fewer side effects compared to the active control. In the case of time-to-event endpoints, existing methods of sample size calculation are done either assuming proportional hazards between the two study arms, or assuming exponentially distributed lifetimes. In scenarios where these assumptions are not true, there are few reliable methods for calculating the sample sizes for a time-to-event noninferiority trial. Additionally, the choice of the non-inferiority margin is obtained either from a meta-analysis of prior studies, or strongly justifiable ‘expert opinion'', or from a ‘well conducted'' definitive large-sample study. Thus, when historical data do not support the traditional assumptions, it would not be appropriate to use these methods to design a noninferiority trial. For such scenarios, an alternate method of sample size calculation based on the assumption of Proportional Time is proposed. This method utilizes the generalized gamma ratio distribution to perform the sample size calculations. A practical example is discussed, followed by insights on choice of the non-inferiority margin, and the indirect testing of superiority of treatment compared to placebo.KEYWORDS: Generalized gamma, noninferiority, non-proportional hazards, proportional time, relative time, sample size  相似文献

Community attachment is the feeling of being connected to community life. Within the community attachment literature, two classic approaches frame scholars’ understanding of this important dimension of community life: the linear development and systemic models. Our empirical models emphasize different factors for community attachment, including population size, density, and heterogeneity for the linear development model and age, length of residence, and social status for the systemic model. Surprisingly, heterogeneity has been omitted from analyses of the linear development model throughout the literature since its introduction, a shortcoming our study addresses. Though heterogeneity can be conceptualized in a number of ways, a large—and growing—body of literature focuses on the effects of race and ethnicity for communities. Here, we focus on a particular type of ethnic heterogeneity—European ancestry—and reincorporate this essential dimension of communities back into the linear development model of community attachment. Using data from the 2004 wave of the Iowa Community Survey and multilevel modeling techniques, we explore how white ethnic diversity matters for community life. We conclude with a discussion of the implications of our study, including potential avenues for future research focusing on other ethnicities that are often subsumed under broader racial and panethnic labels.  相似文献

This article responds to calls in this journal for increased attention to identity, culture, power and sport. It explores, for the first time, the lived realities of identity politics in a divided society, through interviews with 12 self-declared Irish nationalists and republicans that represented Northern Ireland. Important insights are revealed into national eligibility decisions for either Irish team, motivated mainly by ‘shop window’ visibility and being seen as the best of a peer group. Political and sporting nationalisms were not necessarily analogous. A significant original finding is that the lived experiences of being closer to ‘the other’ resulted in an overall reinforcement rather than dissolution of difference. Visual and oral ‘national’ symbols such as flag, and especially anthem, delineated such difference, being symbolic walls of the mind. ‘Our wee country’ was thus a polarised and polarising fantasy shield. The article concludes by reconsidering the role of sport as a lens through which to examine identity and its’ place as part of the ‘problem’ and ‘solution’.  相似文献
