Summary. For rare diseases the observed disease count may exhibit extra Poisson variability, particularly in areas with low or sparse populations. Hence the variance of the estimates of disease risk, the standardized mortality ratios, may be highly unstable. This overdispersion must be taken into account otherwise subsequent maps based on standardized mortality ratios will be misleading and, rather than displaying the true spatial pattern of disease risk, the most extreme values will be highlighted. Neighbouring areas tend to exhibit spatial correlation as they may share more similarities than non-neighbouring areas. The need to address overdispersion and spatial correlation has led to the proposal of Bayesian approaches for smoothing estimates of disease risk. We propose a new model for investigating the spatial variation of disease risks in conjunction with an alternative specification for estimates of disease risk in geographical areas—the multivariate Poisson–gamma model. The main advantages of this new model lie in its simplicity and ability to account naturally for overdispersion and spatial auto-correlation. Exact expressions for important quantities such as expectations, variances and covariances can be easily derived. 相似文献

This study explores the problems of entry by middle-class Irish migrants into respectable urban elite networks in British towns. Although opportunities to participate in political, cultural and charitable institutions were plentiful in nineteenth-century urban Britain, few Irish migrants achieved such distinctions. In the context of south Wales, this was because there were few opportunities for Irish migrants to acquire the necessary occupational status for entry into public life. Those Irish who worked in 'middle class' occupations, were more likely to do so in the retail and service sectors than in the professions, from which ranks local 'worthies' were more likely to be drawn. As a result, they struggled to attain status and remained on the margins of respectable Welsh middle-class life. For these Irish, the 'ethnic sphere' provided an alternative network within which status and recognition could be achieved. 相似文献

This study investigates the relative roles of school district and school-level decision-makers in the implementation of effective substance use prevention curricula. Drawing on a "Site-Based Management" approach to effective decision-making, we hypothesized that schools whose personnel played active decision-making roles would be more likely to implement effective curricula than those in which decision-making was the prerogative of school district personnel. Study data comprised 1369 questionnaires completed by a representative national sample of both district-level prevention coordinators and middle school-based lead prevention teachers. From the perspective of the lead prevention teachers, the school district-level prevention coordinator was more influential than school staff in selecting effective prevention curricula. However, we did find some support for our hypothesis from our district-level informants, who indicated that community groups and advisory committees also play a modest role in the selection of such curricula. 相似文献

Interactivity has been shown to be a critical element of effective drug abuse prevention programs. This study examined the contents of Project Towards No Drug Abuse, a program that has revealed strong effects only when delivered in a highly interactive version. Types of teacher and student interactive messages were identified. It is speculated that explicit action on the part of the teacher to have students make statements and ask questions of one another may be the essence of effective drug education program delivery. Suggestions for future research on interactivity were made. 相似文献

This article surfaces issues about the often-used but widely under-reported practice of working with advisory fora. We critically reflect on our experiences working with an advisory network when co-designing a research study about a ‘sensitive’ subject. We discuss the following: 1) How the network evolved as a matter of ethical and pragmatic choices; 2) Potential issues when discussing sensitive issues ‘outside’ of the participatory or participant context; and 3) Practical and epistemic issues involved in (not) ‘taking’ advice. We suggest that although sensitive research is more conventionally aligned with more ‘radical’ forms of participatory practice, advisory networks can present a useful and sometimes more appropriate form of inclusion and engagement for some advisors and for some types of research study. The article should, therefore, be of interest to a wide range of academic and practice-based health and social care staff and, in particular, those who plan to use advisory fora in their work. 相似文献

The present study provides an implementation fidelity, process, and immediate outcomes evaluation of Project Towards No Drug Abuse (TND), a drug prevention program targeting continuation high school youth (n=1426) at risk for drug abuse. A total of 24 schools participated in three randomized conditions: TND Only, TND and motivational interviewing follow-up, and no treatment control. Fidelity was high: across program schools the curriculum was implemented as intended and was received favorably by students. Relative to controls, intervention conditions produced effects on hypothesized mediators, including greater gains in program related knowledge, greater reductions in drug use intentions, and positive changes in motivation. However, few generalizations to attitudes and intentions regarding risky sexual behavior were found. The pattern of results suggests that the experimental manipulations worked as intended. 相似文献

Students with disabilities are a growing population in higher education (National Center for Education Statistics, 2009). Providing accommodations for students with disabilities can raise ethical and social justice questions and pose challenges for social work faculty, administrators, and field instructors. Social work educators must balance the legal mandates for nondiscrimination and reasonable accommodation against ethical obligations around protection of clients and preparation for practice. This article presents case examples in the context of legal analysis to help social work educators make difficult decisions about student academic performance. 相似文献

Using a creative interdisciplinary method of enquiry, this article seeks to exorcise the spectres of revolutionary creolisation embedded in George Washington Cable’s 1880 novel The Grandissimes. It probes, in particular, the secreted traces of the Creole diaspora triggered by the Haitian Revolution of 1791–1804, and attempts to peel back the manifold layers of ideological occlusion embedded in the (ostensibly white, Anglo-American) narrative frame of Cable’s omniscient narrator and his protagonist Joseph Frowenfeld, which suppress the connections between inter-American identities across diverse, revolutionary, creolistic worlds in Louisiana and the Gulf South. Unlike other studies examining traces of the Haitian Revolution in The Grandissimes, which tend to focus on the parallels between fictional and historical figures in Cable’s southern romance, this article dissects the subtle allusions to the revolution and the attendant diaspora found in the plantation infrastructures and the urban landscape of Cable’s Louisiana. In so doing, it demonstrates how Saint-Domingan migrants affirmed and reinvigorated the cultural landscape of the ‘Creole’ South and ‘circumvented’ the ideological spread of ‘Americanness’ at the time of the Louisiana Purchase, and during successive moments thereafter. 相似文献
