Contemporary textbooks exhibit competing historical perspectives regarding so-called “emerging” organized crime groups. Some texts argue that organized crime committed by groups other than Sicilian/Italian-Americans is now emerging. Others hold that many of the “emerging” groups have been organizing crime for some time and that it is the research in this area that is emerging. This paper briefly examines these propositions, presenting the two groups of thought regarding African-American organized crime. The author then presents a literature review of African-American organized crime research to assist scholars and instructors attempting to better understand the competing perspectives.  相似文献

Abstract

Interventions aimed at increasing the participation of young people with disabilities in recreational sport have had mixed success. The authors draw on in-depth interviews with representatives from State Sporting Associations, local government officers and volunteers within community sports clubs in Victoria, Australia, to examine why some sports clubs are unable or unwilling to translate policy ambitions into practice. The findings indicate how by framing disability provision as ‘too difficult’, ‘not core business’ and antithetical to competitive success, community sports clubs are able to resist policy ambitions to modify existing structures and develop more inclusive practice. Greater priority needs to be given to transformational inclusion objectives and challenging ableism if clubs are to structurally progress the development of participation opportunities for young people with disabilities.  相似文献

ABSTRACT

Contemporary museums must balance their roles as commercial entities and repositories of various, and often dissonant, heritages and histories. Sports museums in particular often have clear commercial and nostalgic aims, particularly through tourist visitation, though the extent to which they represent more challenging narratives remains unclear. This paper examines how one of the most famous sports museums in the world, the National Baseball Hall of Fame (NBHF) in Cooperstown, New York, balances its dual role as tourist attraction and repository of baseball's sometimes checkered past. It was found that different sections of the museum provide greater or lesser degrees of engagement with more controversial issues, although the commercial outputs and appeal of the museum remains clear throughout. Utlimately, the NBHF demonstrates that balancing veneration and critique in collections can be commercially prosperous, and can provide a template for other sport and popular culture museums who may be wary of incorporating more challenging narratives in their exhibits. Furthermore, the symbiotic relationship between the Hall of Fame and the village of Cooperstown, particularly in creating and maintaining cultural and economic outputs, requires further exploration.  相似文献

Eating rates (bites per interval) and other meal behaviors (number of chews, sips, talks with a neighbor, and chews per bite) were observed for 30 normal and 30 overweight white preschool children in their school cafeterias. Children were classified according to weight (overweight or normal), age (1 1/2--2 years, 3--4 years, or 5--6 years) and sex. Analysis of variance revealed that overweight preschool children demonstrated a somewhat higher rate of distinctly fewer chews per bite. Boys showed increasing chew rates with increasing age. Talk rates also increased with age but were unrelated to sex or weight status. Sip rates were not significantly associated with age, sex, or weight status. These results support the hypothesis that overweight persons are characterized by an increased eating rate and show that it is apparent even around the time of first self-feeding.  相似文献

To determine if actual practice was consistent with commonly recommended research methods and procedures, this study examined 130 studies reported over a 5-year period in three volumes of the Journal of Research in Science Teaching (JRST). The results were consistent with similar previous analyses (Shaver & Norton, 1980a, 1980b; Wallen & Fraenkel, 1988a) and indicate that appropriate generalizations beyond the confines of the reported studies may be impossible for most (64%) of the JRST studies surveyed. The findings also show that replication studies, which could be employed to offset deficiencies in generalizability, were not commonly encountered (3%) in these 130 reports. In addition, the study results indicate that many researchers (48%) do not properly restrict their conclusions based on the limits imposed by the accessible populations and samples used; nor do they typically provide possible alternative explanations for the outcomes obtained (76%). These findings prompt the following recommendations: 1. A greater awareness and use of replication as a check on generalizability should be encouraged by the science education community. 2. Clearly defined populations (target and accessible) and fully described samples warrant increased attention as report components from authors, reviewers, and editorial board members of JRST. 3. In light of the difficulties inherent in effecting random selection in educational settings, a greater emphasis should be placed on recognizing the limits that the underlying assumptions of inferential statistics place on research conclusions. The results of this study indicate that the methodological quality of published science education research should remain a concern for both practitioners and readers.  相似文献

Educational analysts studying achievement and other educational outcomes frequently encounter an association between initial status and growth, which has important implications for the analysis of covariate effects, including group differences in growth. As explicated by Allison (1990 Allison, P. D. (1990). Change scores as dependent variables in regression analyses. Sociological Methodology, 20, 93114.[Crossref] [Google Scholar]), where only two time points of data are available, identifying a preferred model can be difficult or impossible. In this paper we extend Allison's inquiry by considering multiple sources of the association between initial status and growth simultaneously, including measurement error but also intrinsic associations between initial status and growth. We illustrate the potential trade-offs between the change-score model specifications (models without a control for initial status) and regressor-variable specifications (with a control for initial status) using simulated data.  相似文献
