The author describes Contra Costa County's efforts to implement Healthy Families 2000, the County's vision of neighborhood-based, family-centered, comprehensive integrated services in two of the county's unincorporated areas, North Richmond and Bay Point. Contra Costa County is one of six bay area counties, northeast of San Francisco. It has nearly 800,000 residents and is home to some of the wealthiest communities in the state as well as some of the poorest neighborhoods. This article provides a systematic review of the process and a discussion of the operating practices and principles guiding Contra Costa's significant effort to change its service delivery approach, anticipating that this experience might be helpful to others as they develop a neighborhood-based human services partnership with community leaders and residents.  相似文献

Model selection strategies play an important, if not explicit, role in quantitative research. The inferential properties of these strategies are largely unknown, therefore, there is little basis for recommending (or avoiding) any particular set of strategies. In this paper, we evaluate several commonly used model selection procedures [Bayesian information criterion (BIC), adjusted R 2, Mallows’ C p, Akaike information criteria (AIC), AICc, and stepwise regression] using Monte-Carlo simulation of model selection when the true data generating processes (DGP) are known.

We find that the ability of these selection procedures to include important variables and exclude irrelevant variables increases with the size of the sample and decreases with the amount of noise in the model. None of the model selection procedures do well in small samples, even when the true DGP is largely deterministic; thus, data mining in small samples should be avoided entirely. Instead, the implicit uncertainty in model specification should be explicitly discussed. In large samples, BIC is better than the other procedures at correctly identifying most of the generating processes we simulated, and stepwise does almost as well. In the absence of strong theory, both BIC and stepwise appear to be reasonable model selection strategies in large samples. Under the conditions simulated, adjusted R 2, Mallows’ C p AIC, and AICc are clearly inferior and should be avoided.  相似文献

This paper describes empirical research amongst hooligans. Such research has not always been valued. The significant factor in hooligan behaviour may be asserted to be the generation of violence in the lower working class and its dissemination amongst football fans. It is commonly asserted that hooligans operate in well-organized groups. It is argued here that such assertions need to be based on better evidence. A detailed account is given of the behaviour of a notorious group of fans and its key individuals. This shows that the ‘hard core’ fans were distinguished from others only by greater dedication to football and their club; they had a potentiality for violence but only of the low level kind that many others shared; they were more often involved simply because they went to more matches; they lacked organization. Nevertheless outsiders were, not unreasonably, sure they were a violent, organized group. This casts doubt on similar beliefs held about other groups unless beliefs are well substantiated. Detailed ethnography is valuable because it helps to sort out the nature of the ‘hooligan’ problem that requires to be theorized.  相似文献

This paper examines the politics of mobility which surrounded the London 2012 Olympics. We provide a critical discussion of the mobility conflicts, problems and criticisms which emerged from our research with local people in the Stratford and wider Newham areas of London, where most Olympic events were located. The paper is divided into four broad parts. First, we identify and discuss the relevant components of the ‘mobilities paradigm’ in social science which underpin our analysis. Second, we briefly outline our research methods, centring particularly on fieldwork and interviews with different social groups. Third, we examine in detail the six main themes of mobility politics which were evident at London 2012, relating to social context, event construction, event mobility systems, commercial mobilities, the mobile politics of exclusion, and contested modes of mobility. In doing so, we seek to extend the mobilities paradigm by introducing various concepts and keywords – notably on the three‐speed city, entryability, mobility panics, instrumental mobility, and corporate kettling – which may be utilized by social scientists to examine mobility systems in other social contexts. We conclude by reaffirming the significance of mobility‐focused research at sport and other mega‐events, and by indicating future lines of inquiry for social scientists.  相似文献

This article undertakes a critique of social return on investment (SROI), combining the existing research literature with an analysis of six case studies of supported social enterprises employing people with disabilities and other challenges that affect their access to the conventional labor market. The critique of SROI focuses on its positivist roots and its emphasis on one number, the SROI ratio. It also discusses the technical challenges in producing that number, including concerns about its reliability. The article presents the stakeholder impact statement, an approach that is rooted in interpretivism and attempts to understand the impact of enterprises through the eyes of multiple stakeholders. Unlike SROI, which is a supplement to conventional accounting statements, the stakeholder impact statement integrates financial and social impact data, thereby placing them on the same level of importance.  相似文献

Youth suicide is a leading cause of mortality. Greater still is the prevalence of suicidal behavior and ideation. In this study with 813 secondary school students, we explored youth engagement in structured extracurricular activities as a possible protective factor for suicidal ideation. Personally meaningful youth engagement significantly moderated the relationships between depressive symptoms, risk behaviors, self‐esteem, and social support in the prediction of suicidal ideation. Specifically, the more meaning found in engagement, the less likely youth were to report suicidal thoughts in spite of risk factors. Acknowledging limitations, a focus on engaging youth in well‐selected activities of interest might represent a nonstigmatizing approach to universal prevention. Further research into the mechanisms of such an approach is warranted.  相似文献
