A random digit dialing telephone survey was used to interview 8,467 adults in Ontario, Canada. The NODS-CLiP was used to identify a representative sample of 730 gamblers (54.3% male, mean age 45.3 years) with possible past year gambling problems in order to explore factors that might affect disordered gamblers’ motivators for seeking gambling-related help. A final sample of 526 gamblers provided useable data on possible reasons for and barriers to seeking help, awareness of services, self-perception of gambling problems and experience with help-seeking. Financial and relationship issues were the most frequently volunteered motivators. However, over two-thirds of the respondents could not think of a reason for seeking help. Gamblers who had self-admitted or more severe problems, who knew how to get help, who were employed and had more education, and who identified possible barriers to seeking help were more likely to suggest motivators, especially financial ones. More research is recommended on gamblers’ trajectory towards recognition of a gambling problem, the process of overcoming specific barriers to treatment, and the role of social advantage (e.g., education and employment), in order to devise educational campaigns that will encourage earlier help-seeking among disordered gamblers.  相似文献

埃德加·莫兰的复杂性思想主体包括三大理论:建立在有序性与无序性统一基础上的自组织理论、建立在整体与部分相互决定基础上的多样性理论以及建立在主客体相整合基础上的自我反思理论.莫兰的复杂性思想与"简单范式"针锋相对,自然构成了时以"简单范式"为基础的人类学的批判.本文以人类学研究的某些方面,如研究主体、文化的整体性、观察角度、价值取向、工作思路、研究态度以及研究角色等为例,进行了评析.  相似文献

This study utilized the community structure approach to analyze newspaper coverage of posttraumatic stress (PTS) in veterans in 26 U.S. cities. The study examined whether media placed responsibility for PTS treatment on government or society through a review of 353 articles from March 20, 2003, to March 20, 2013. Researchers coded articles for “prominence” and “direction” to produce a “Media Vector” for each paper, ranging from 0.8403 to ?0.3592. Results showed that 25 of 26 Media Vectors (96%) supported government responsibility. Pearson correlations yielded nine significant findings. Results disconfirmed buffer hypotheses linking privilege with support for government responsibility (privilege defined by percentage of college educated, percentage of family income $100,000 or more, and percentage of professional/technical occupational status; r = ?.486, ?.524, ?.553, respectively, significant at the .006 level). Stakeholder hypotheses were also disconfirmed; greater percentages of age 65 and older correlated with more emphasis on government responsibility (r = .340, p = .048), whereas greater percentages of age 25 to 44 correlated with less emphasis (r = ?.342, p = .047). The only confirmed hypothesis linked percentage of age 45 to 64 with less emphasis on government responsibility (r = ?.559, p = .002). A regional finding was noteworthy: Media in the Midwest supported government responsibility more than other regions. Regression analysis revealed three variables influencing coverage most significantly: Family Income $100K+ (26% of variance), Percentage of Hispanic (8%), and Professional/Technical Occupational status (5%). It must be noted that nearly all newspapers yielded positive Media Vectors. This indicates that coverage in major cities generally favors government responsibility for veterans' PTS treatment, and Pearson correlation results may represent differences in the degree of support and demographic characteristics influencing this support.  相似文献

Although usually conceived of and studied as individual types, genres are frequently combined in practice. This research examines how genres are combined in popular American films, and how the popularity of particular combinations changed between 1946 and 2013. Distinguishing between “contextual genres” (which identify a film's subject matter) and “affective genres” (which identify a film's intent), we find marked differences between the postwar and blockbuster eras of the Hollywood film industry. The blockbuster era exhibits less generic diversity than the earlier postwar era. Furthermore, the popular postwar‐era films dealt with serious subjects and were set in realistic settings. The blockbuster era replaced these with intense, nonrealistic films. We also find that the relationship between contextual and affective genres changes within industry eras, with affective genres dominating at the beginning of new periods and the popularity of contextual genres growing as the period progresses.  相似文献

Les relations entre les centres de recherche ou groupes de réflexion et leurs bailleurs de fonds sont importantes dans les théories et les discours publics abordant la question de l'orientation politique de la recherche sur les politiques publiques. Pourtant, très peu d'études examinent systématiquement ces relations à travers un ensemble de cas. Cet article, avec des méthodes comparatives et relationnelles, teste les théories élitiste, pluraliste et de terrain, en analysant des données portant sur le financement et l'orientation politique de 30 groupes de réflexion de 2000 à 2011. Les résultats démontrent que les dons provenant de l'étranger contribuent à soutenir certains groupes de réflexions conservateurs, mais ce financement demeure tout de même marginal dans l'ensemble. Au niveau national, les groupes de réflexion sont financés de manière contrastée: les groupes conservateurs sont financés principalement par des donateurs privés, alors que les groupes de réflexion centristes sont financés principalement par l'état. Depuis 2005, les liens entre l'ensemble des groupes de réflexion conservateurs, financés par des donateurs privés, sont devenus plus serrés. En revanche, les liens entre l'ensemble des groupes de réflexion centristes se sont relâchés et leur financement dépend de plus en plus de leurs propres revenus et des intérêts de leurs investissements. Ces résultats laissent planer un certain doute sur les prédictions qui découlent des théories élitiste et pluraliste et confirment en partie les suppositions de la théorie de terrain. The relationships between think tanks and their funders are central to theory and public discourse about the politics of policy knowledge, yet very little research systematically examines these relationships across cases. This article evaluates elite, pluralist, and field theories by analyzing original data on funding and politics for 30 think tanks from 2000 to 2011 with comparative and relational methods. I find that foreign donations help support some conservative think tanks, but that it is a small amount of money relative to other funding sources. Domestically, think tank funding is structured by an opposition between donor‐funded conservatives and state‐funded centrists. Since 2005, the cluster of conservative think tanks funded by private donors has become tighter, while the cluster of think tanks supported by the state has become looser and more reliant on self‐generated revenue and interest and investments. These findings cast doubt on predictions derived from elite and pluralist theories, and offer some support for field theory.  相似文献

Scheduling university examinations is often done with the objective of spreading a student's required examinations over an examination week. That is the equivalent of the problem of minimizing the number of examinations a student must take on any one day. An approach to scheduling exams which relates the problem to the classical assignment problem is discussed. The model developed is a symmetry-constrained assignment model, and the solution method requires use of a branch-and-bound algorithm. Results from application of the algorithm to six semesters of actual data are presented.  相似文献
