The concepts of the public sphere and public space have gained increasing purchase within social history. This paper contributes to this literature by theoretically developing a critical approach to both concepts. By drawing upon the insights of the Bakhtin circle, as well as Marxism and Poststructuralism, the paper suggests that public spheres under capitalism are structured through the basic contradiction between capital and labour. Each public sphere may then be seen as a refracted dialogic and spatial form of this basic contradiction, and is then best viewed as a contradictory spatial entity that obtains its unique identity through different "accents" and "word signs". The capitalist state must aim to regulate, through governance and law, dialogue within a public sphere. By focusing on the Chartist demonstration at Hyde Park, London in 1855, I show how these theories can be employed to explore how a radical social movement appropriated space by developing a working class public sphere. 相似文献

Motivators for Resolving or Seeking Help for Gambling Problems: A Review of the Empirical Literature
Helen Suurvali David C. Hodgins John A. Cunningham 《Journal of gambling studies / co-sponsored by the National Council on Problem Gambling and Institute for the Study of Gambling and Commercial Gaming》2010,26(1):1-33
This literature review summarizes recent empirical research on the reasons disordered gamblers try, through treatment or otherwise,
to resolve or reduce their gambling problems. Relevant databases and bibliographies were searched for English-language studies,
published since 1998, that asked gamblers themselves about motivators for action. Found were ten studies addressing reasons
for trying to resolve or reduce gambling problems, five addressing reasons for seeking help and four addressing reasons for
requesting self-exclusion from casinos. Help-seeking occurred largely in response to gambling-related harms (especially financial
problems, relationship issues and negative emotions) that had already happened or that were imminent. Resolution was often
motivated by the same kinds of harms but evaluation/decision-making and changes in lifestyle or environment played a more
prominent role. Self-exclusion was motivated by harms, evaluation/decision-making and a wish to regain control. Awareness
and educational materials could incorporate messages that might encourage heavy gamblers to make changes before harms became
too great. Intervention development could also benefit from more research on the motivators leading to successful (vs. failed)
resolution, as well as on the ways in which disordered gamblers are able to overcome specific barriers to seeking help or
reaching resolution. 相似文献

This article uses the history of debates over the US Head Start programme (1965), Early Head Start (1994) and the UK Sure Start initiative (1998), as a window on to policy transfer. In all the three, the aim was that early intervention could offer a means of boosting children’s educational attainment and of countering the wider effects of poverty on development. Nevertheless, there were also important differences between them. The first part of the article looks at UK responses to Head Start, the second at Early Head Start and the creation and subsequent direction taken by Sure Start. In the Conclusion, we sum up the arguments relating to Head Start and Sure Start and offer some broader reflections on policy transfer. 相似文献

Testing for homogeneity in finite mixture models has been investigated by many researchers. The asymptotic null distribution of the likelihood ratio test (LRT) is very complex and difficult to use in practice. We propose a modified LRT for homogeneity in finite mixture models with a general parametric kernel distribution family. The modified LRT has a χ-type of null limiting distribution and is asymptotically most powerful under local alternatives. Simulations show that it performs better than competing tests. They also reveal that the limiting distribution with some adjustment can satisfactorily approximate the quantiles of the test statistic, even for moderate sample sizes. 相似文献

The quadratic discriminant function is commonly used for the two group classification problem when the covariance matrices in the two populations are substantially unequal. This procedure is optimal when both populations are multivariate normal with known means and covariance matrices. This study examined the robustness of the QDF to non-normality. Sampling experiments were conducted to estimate expected actual error rates for the QDF when sampling from a variety of non-normal distributions. Results indicated that the QDF was robust to non-normality except when the distributions were highly skewed, in which case relatively large deviations from optimal were observed. In all cases studied the average probabilities of misclassification were relatively stable while the individual population error rates exhibited considerable variability. 相似文献

This project evaluated the extent to which businesses with a primary purpose of providing opportunities for sexual encounters between men (e.g., bathhouses and sex clubs) have implemented strategies that target their customers with important HIV and STD prevention messages. Between October 1996 and February 1997, we conducted structured telephone interviews with 63 businesses throughout the United States in order to describe their facilities and their HIV education and prevention efforts. Types of facilities offered were related to what businesses called themselves and the kinds of sex space they provided. All of the businesses reported that they provided condoms and lubricant on site; 95% provided educational materials such as posters and flyers about HIV/AIDS; and 40% provided HIV testing on site, with half of these also providing some type of STD testing. Although some level of HIV prevention and educational efforts by these businesses are described, further investigation into their efficacy is required. 相似文献

Abstract There is a controversy regarding the meaning of occupational status centering around the issue of whether status differences continue to entail deference entitlement. This article suggests that deferential behavior is still linked to occupational status differences but, as a result of the complexity of occupational systems in industrial societies, there have been changes in the settings in which displays of deference occur and in the manner in which deference is expressed A source of confusion in the debate on the meaning of occupational status is the failure to distinguish between differences in status and differences in the occupational characteristics on a basis of which status is accorded This distinction and its implications for class and power hierarchies are discussed The article concludes with an argument for the necessity of situating the process of status differentiation in “status assignment systems”. 相似文献
