The prevalence of verbal and physical aggression on daytime television talk shows has earned this genre the designation of “confrontainment.” In recent times academics, politicians, clergy, and media critics have frequently and publicly expressed their concern about the violation of moral values featured on the “The Jerry Springer Show.” On the other hand, sociologists in the functionalist tradition argue that commonly held moral values must be violated and the villains publicly punished for their transgressions to mark and reinforce moral boundaries. The goal of the study reported here was to assess the potential of “The Jerry Springer Show” for fulfilling these social maintenance functions. A content analysis of 100 episodes of the show over an eight-month period revealed that deviance from traditional family values is frequently featured on the show but that the studio audience and Jerry Springer played active roles in the public degradation of these transgressions, casting the show in a morally conservative light.  相似文献

Abstract

The aims of this study were: (1) to characterize selected fitness and health attributes of two types of habitual recreational off-road vehicle riders – off-road motorcyclists and all-terrain vehicle riders; (2) to explore differences among riders in terms of vehicle type, age, and gender; and (3) to compare the fitness and health of riders to population norms and clinical health standards. Canadian off-road riders (n = 141) of both sexes aged 16 years and over were recruited through local and national off-road riding organizations. Anthropometry, fitness, and health measures of off-road motorcycle and all-terrain vehicle riders were compared with population norms, health standards, and physical activity guidelines. Off-road motorcycle riders had above average aerobic fitness (79th percentile), while all-terrain vehicle riders were lower than average (40th percentile). All riders had a healthy blood lipid profile and a low incidence of the metabolic syndrome (12.9%) compared with members of the general population. Off-road motorcycle riders had healthier body composition and fitness than all-terrain vehicle riders; however, the body composition of off-road motorcycle riders was no healthier than that of the general population and all-terrain vehicle riders were worse than the general population. Off-road motorcycle riders had healthier anthropometry and fitness than all-terrain vehicle riders and thus fewer health risk factors for future disease, demonstrating that the physiological profiles of off-road riders are dependent on vehicle type.  相似文献

This article focuses on counseling research in the community college context. The article suggests the need for a robust community college knowledge base, describes some limitations of the current community college literature, and suggests a framework for more effective work in this area. The authors’ own experiences and selected examples of published studies are used as illustrations of the hurdles encountered and solutions available when examining counseling theories, practices, and outcomes in 2‐year settings.  相似文献

This article briefly discusses the long history of violence towards disabled people which sets the context for an analysis of the modern‐day form of violence known as disability hate crime (DHC). People who look or behave differently to others often find themselves victims of violent crimes. The language used to describe disabled people contributes to their diminished position in society. A brief review of definitions of DHC and exploration of news media coverage of the Pilkington and Askew DHC cases are undertaken. Cultural scapegoating of disabled people is discussed. Disabled people are perceived as contributing to their own victimisation, the lack of support afforded to them by society and the failure of systems meant to protect them. As long as disabled people remain outside mainstream society, they are unlikely to achieve the same levels of respect and protection from crime that other groups in society are afforded.  相似文献

Associations among adolescent attachment organization, maternal sensitivity, and infant attachment organization were examined prospectively in 74 teenaged mother-infant dyads. Pregnant teenagers' attachment organizations predicted both sensitivity and infant-mother attachments. Mothers classified autonomous (F) in the prenatal period showed higher levels of sensitivity at both 3 and 9 months than mothers classified dismissing (Ds), preoccupied (E), or unresolved (U). Correspondence between maternal attachment (F vs. Ds/E/U) and infant attachment (secure [B] vs. avoidant [A]/resistant [C]/ disorganized [D]) was observed in 58 of 74 (78%) dyads. Exact 4-group (Ds/E/F/U and A/B/C/D) agreement was observed in 50 of 74 (68%) families. In contrast, associations between maternal sensitivity and infant attachment were not significant, leading to questions about the processes that link attachment representations, maternal behavior, and infant attachment in adolescent mothers.  相似文献

This article explores recent developments inthe regulation of Internet speech, inparticular, injurious or defamatory speech andthe impact the attempts at regulation arehaving on the `body' in the sense of theindividual person who speaks through the mediumof the Internet and upon those harmed by thatspeech. The article proceeds in threesections. First, a brief history of the legalattempts to regulate defamatory Internet speechin the United States is presented; a shortcomparative discussion of defamation law in theUK and Australia is included. As discussedbelow, this regulation has altered thetraditional legal paradigm of responsibilityand, as a result, creates potential problems forthe future of unrestricted and even anonymousspeech on the Internet. Second, an ethicalassessment is made of the defamatory speechenvironment in order to determine which actorshave moral responsibility for the harm causedby defamatory speech. This moral assessment iscompared to the developing and anticipatedlegal paradigm to identify possible conformityof moral and legal tenants or to recognize theconflict between morality and law in assigningresponsibility to defamatory actors. Thisassessment then concludes with possiblesuggestions for changes in the legal climategoverning the regulation of defamatory speechon the Internet, as well as prediction of theresult should the legal climate continue todevelop on its present course. This is not tosuggest that all law, or even the law ofdefamation, be structured to reflect thesubjectivity of a moral construct, but since itis the authors position that the legalassignment of liability in online settings ismisaligned, this reflection can serve asbeginning reassessment of that assignment.  相似文献

This study considers how institutional histories of admitting women are associated with present college experiences, and uses data from the Wabash National Study of Liberal Arts Education to compare the experiences of women at women’s colleges or former women’s colleges to those of women at former men’s colleges and colleges that have always been coeducational. Results indicate that women attending former men’s colleges and colleges that have always been coeducational seem to experience similar or greater frequency and quality of student–faculty interaction and exposure to good teaching practices, compared to women attending women’s or former women’s colleges. Results also suggest that considering the gender enrollment histories of colleges and universities may provide valuable context for evaluating the experiences of women at women’s colleges and coeducational institutions.  相似文献
