A substantial portion of gamblers in treatment may have co-occurring mental health disorders including substance use disorders, especially alcohol dependency, personality disorders, affective disorders, anxiety disorders and impulse control disorders. Co-occurring mental health disorders affect treatment seeking, the treatment process and its outcome, quality of life and functioning in many mental health disorders. Participants in this study were 78 adults enrolled in state-supported out-patient services for pathological gambling and current Gamblers Anonymous attendees. The majority of participants (76.6%) had co-occurring behaviours; 55.8% had multiple co-occurring behaviours. Participants with multiple co-occurring behaviours were more likely to report that a co-occurring behaviour increased the severity of their gambling symptoms. A dose/response relationship between number of co-occurring behaviours and severity of gambling problems was found. Co-occurring behaviours can interact with gambling behaviour. Brief, validated screening instruments are available for screening and diagnosing co-occurring behaviours among gamblers presenting for treatment.  相似文献

Tree-based methods similar to CART have recently been utilized for problems in which the main goal is to estimate some set of interest. It is often the case that the boundary of the true set is smooth in some sense, however tree-based estimates will not be smooth, as they will be a union of ‘boxes’. We propose a general methodology for smoothing such sets that allows for varying levels of smoothness on the boundary automatically. The method is similar to the idea underlying support vector machines, which is applying a computationally simple technique to data after a non-linear mapping to produce smooth estimates in the original space. In particular, we consider the problem of level-set estimation for regression functions and the dyadic tree-based method of Willett and Nowak [Minimax optimal level-set estimation, IEEE Trans. Image Process. 16 (2007), pp. 2965–2979].  相似文献

The purposes of this study were (a) to determine whether women's use of persuasion, non‐physical coercion, and physical force strategies to obtain sex from a man varied between U.S. women from an urban Southern and rural Midwestern university and (b) to determine if sexual behavior history and early courtship behavior affected the use of these strategies (or not using any strategy). Women from the Midwest and the South did not differ in their use of sexual strategies. There were, however, other variables that accounted for differences in women's use of sexual strategies. Women who used persuasion strategies had fewer lifetime sexual partners than women who used any other strategy. Women who used physical force strategies reported a lower age at first intercourse and more early courtship behaviors than all others. Overall, the results indicated that sexual strategies are related to sexual behavior history and early courtship behaviors rather than cultural setting or demographics.  相似文献

This essay combines Burke's burlesque frame and Jamieson's double binds to create a hybrid gendered theory for rhetorically analyzing the aggressive sexualization of 2008 United States vice presidential candidate Sarah Palin. The essay develops our theory titled the “burlesque binds” and explicates a specific form of a burlesque bind: the “MILF frame.” Palin's aggressively sexualized representation was united under the crass acronym MILF, which stands for “Mom I'd Like to Fuck.” The MILF frame emphasized Palin's feminine qualities, positioning her as a “trophy vice” with no political acumen, and highlighted her masculine behaviors, but deflated them through sexual objectification. The unification of the binds and burlesque theories reveals how Palin's role as a social actor was not simply circumscribed but shut down: she was deemed unfit by both masculine and feminine standards, by both public and private sphere conventions. Although Sarah Palin has arguably been the most prevalent subject of the political MILF frame, our essay catalogues other instances of female political leaders experiencing this type of symbolic degradation, suggesting the MILF frame's vast influence.  相似文献
