Cinquante‐six garçons du secondaire ont expliqué pourquoi ils avaient perpétré ou non certains actes de délinquance (combat, vandalisme, vol à l'étalage, usage de drogues). Ils ont aussi ciblé des théories sociologiques de la délinquance qui s'appliquent à leur comportement. Leurs réponses montrent que les deux types de données se recoupent beaucoup. L'effort, la théorie gánérate, les pairs, le contrôle social, les techniques de neutralisation et la prévention sont importants, mais non l'étiquetage ni l'imitation des médias. Une théorie de contingence de la délinquance est proposée. Fifty‐six high school boys were asked to explain in their own words why they had engaged in or refrained from certain delinquencies: fighting, vandalism, petty theft, truancy and drug use. They were also given the opportunity, via a checklist, to tell whether selected sociological theories applied to their behaviour. Their responses revealed considerable overlap in the two forms of data. Strain, general theory, peers, social control, techniques of neutralization and deterrence are important in varying combinations. Labelling and media imitation are not. A contingency theory of delinquency is proposed.  相似文献

A prevalence of heavy-tailed, peaked and skewed uncertainty phenomena have been cited in literature dealing with economic, physics, and engineering data. This fact has invigorated the search for continuous distributions of this nature. In this paper we shall generalize the two-sided framework presented in Kotz and van Dorp (Beyond beta: other continuous families of distributions with bounded support and applications. World Scientific Press, Singapore, 2004) for the construction of families of distributions with bounded support via a mixture technique utilizing two generating densities instead of one. The family of Elevated Two-Sided Power (ETSP) distributions is studied as an instance of this generalized framework. Through a moment ratio diagram comparison, we demonstrate that the ETSP family allows for a remarkable flexibility when modeling heavy-tailed and peaked, but skewed, uncertainty phenomena. We shall demonstrate its applicability via an illustrative example utilizing 2008 US income data.  相似文献

In this study, I use in‐depth interview data with black and white heterosexual men to explore shifts in the role of homophobia in the social construction of heterosexual masculinities. A continuum is introduced to map a range of interactional practices through which these men enact heterosexual masculinities. Heterosexual men who, on one end of the continuum, construct their heterosexual masculinities through homophobic practices establish strong boundaries of social distance from gays. The other end documents heterosexual men's anti‐homophobias, moving from men who establish weak boundaries to those who blur them. These heterosexual men's anti‐homophobic stances trade on the prestige of being tolerant of gays, with black men's anti‐homophobias drawing on their experiences with racism.  相似文献

Open-ended interviews with 24 couples therapy clients regarding their experience of the process of change revealed shifts in clusters of affect, communication, and cognition. Six additional contextual preconditions for change were also identified. The change process within couples was uniformly reported to be gradual.  相似文献

Elderly drivers are increasing in number and some statistics show they are more likely to be involved in fatal accidents than all other age groups but those under 25. States have attempted to address the problem in various ways, but very few have required mandatory retesting at license renewal for those beyond a particular age. Why have so few states chosen to act? The key is how the issue is framed for the public and decision makers. Several phases of problem definition are explored to explain the political dynamics of the older driver issue: incidence, causality, severity, crisis labeling, problem population characteristics, and linkage of values to the issue and solutions. Based upon this analysis, it is not surprising that elder interest groups have been successful in containing policy initiatives designed to restrict elderly driving.  相似文献

Carbon emissions from fossil fuel use and other human activity are predicted to cause a significant warming of the global climate, according to a growing consensus of scientists. Global warming would have substantial negative effects on the world environment and economy. Human population and economic growth continue to drive both energy use and carbon emissions. While the developed countries are the largest source of present and past emissions, developing countries are rapidly catching up. China will probably surpass the United States as the largest carbon emitter early in the next century. The global warming treaty signed in Rio in 1992 relies entirely on voluntary emission caps for developed countries and has had little or no apparent effect on emissions. Much stronger steps must be taken to avoid or lessen potential climate change. A globally determined but nationally imposed carbon tax should be adopted to internalize the future costs of carbon emissions into the present cost of fossil fuel and other carbon sources. This would allow the maximum use of free market forces and individual choice to determine how carbon emission reductions are achieved. In addition, national emission caps for all countries should be established. International trade mechanisms can be used to support universal implementation of these measures. Where possible, global warming policy should include strong but equitable incentives for sustainable development and population stabilization, important goals in themselves regardless of the extent of future climate change.  相似文献

The quality of adolescents' relationships with residential parents has been found to predict many different health and behavioral youth outcomes; strong associations have also been found between these outcomes and family processes, and between relationship quality and family processes. Data from Rounds 1–5 of the National Longitudinal Survey of Youth, 1997 were used to examine hypotheses about the influence of the parent–adolescent relationship on subsequent adolescent mental well‐being and delinquency, as mediated by family processes. Using structural equation modeling, we found that the influence of a positive residential parent–adolescent relationship on better mental well‐being and fewer delinquency was entirely mediated by family routines, parental monitoring, and parental supportiveness, net of sociodemographic controls.  相似文献

该文认为满语构词附加成分-tu很可能来源于蒙古书面语,是在满蒙书面语的相互接触和影响过程中由蒙古语借入满语的。由此,可以看出蒙古书面语对满语产生了很大的影响。  相似文献
