Summary.  We propose a mixture of binomial and beta–binomial distributions for estimating the size of closed populations. The new mixture model is applied to several real capture–recapture data sets and is shown to provide a convenient, objective framework for model selection. The new model is compared with three alternative models in a simulation study, and the results shed light on the general performance of models in this area. The new model provides a robust flexible analysis, which automatically deals with small capture probabilities.  相似文献

E-optimality is studied for three treatments in an arbitrary n-way heterogeneity setting. In some cases maximal trace designs cannot be E-optimal. When there is more than one E-optimal design for a given setting, the best with respect to all reasonable criteria is determined.  相似文献

In this paper, I focus on the British future from Brexit. The institutional form this will take is not yet fixed. However, one can consider likely outcomes based on dominant economic frameworks. From this perspective, it seems unlikely that Brexit will address the actual grievances that resulted in Brexit. These transcend European Union membership.  相似文献

It has long been recognized that children with a parent or close relative in prison are more likely to experience educational difficulties, emotional distress, family breakdown and a substantial reduction in family income (Boswell 2002; Smith et al. 2007; Morgan et al. 2013b; Morgan and Gill 2013). Consequently, children with a parent in prison are more likely to require support from statutory services, especially education and social care. However, statutory support for this group of children is sparse, and children of prisoners tend not to be identified as a priority group. The demand on local authorities to spend their limited budgets wisely means tough decisions have to be made. These decisions are not taken in a vacuum: they are taken in a context of local need, consumer representation, central and local politics; underpinned by the values and attitudes of individual members as well as by the ethos or culture of the local authority itself. In this article we apply Axford's typology (2009) of the different cultures which underpin local authority service provision to data from a research study carried out in 2011 in one local authority which explored support provision in schools for children of prisoners. We examine the contradictions and gaps within the local authority's attempts to synergize the different modules of service delivery into a coherent pattern of provision, and we explore how changes in strategic culture might lead to improvements being made in terms of service delivery to this group of ‘vulnerable’ children.  相似文献

Little is known about the situational factors associated with gambling behavior. We induced 180 male participants (mean age: 21.6) into a positive, negative, or neutral mood prior to gambling on a video lottery terminal (VLT). While gambling, participants were observed by either a male peer, female peer, or no one. Induced mood had no effect on gambling behavior. Participants induced into a negative mood prior to gambling, however, reported more positive moods after gambling, whereas those with positive and neutral moods reported more negative moods after gambling. Participants observed by either a male or female peer spent less time gambling on the VLT compared to those not observed. Participants observed by a female peer lost less money relative to the other observer conditions. Degree of problem gambling in the last year had little influence on these effects. Some practical implications of these findings are discussed.  相似文献
