Welfare and criminal justice systems manifest different goals, cultures, values and working methods. In Australia, the welfare sector has a culture of empowerment and concern for victims’ rights, within which social workers focus on social justice and social change. In contrast, the criminal justice sector (police) is patriarchal and para-military in structure, focusing on enforcing and maintaining community order and safety. These differences can create tension when social workers and police need to work as partners in response to violence against women, in particular violence against women from bikie gangs. This article addresses the issue of partnerships between social workers and police when working with abused bikie-gang women. It presents the findings of recent research into social work practice with such women in South Australia, in conjunction with a brief exploration of the international literature on social work and police cultures, and partnerships. It concludes that whilst there is a great need for genuine collaboration and partnership between social workers and police in the complex context of domestic violence with links to organised crime, the cultures and mandates of these different professions make this difficult. 相似文献

When we want to compare two designs we usually assume the standard linear model with uncorrelated observations. In this paper we use the comparison method proposed by Ghosh & Shen (2006) to compare three level orthogonal arrays with 18, 27 and 36 runs under a possible presence of correlation in observations. 相似文献

Model-based clustering for social networks 总被引:5,自引:0,他引:5

Summary. Network models are widely used to represent relations between interacting units or actors. Network data often exhibit transitivity, meaning that two actors that have ties to a third actor are more likely to be tied than actors that do not, homophily by attributes of the actors or dyads, and clustering. Interest often focuses on finding clusters of actors or ties, and the number of groups in the data is typically unknown. We propose a new model, the latent position cluster model , under which the probability of a tie between two actors depends on the distance between them in an unobserved Euclidean 'social space', and the actors' locations in the latent social space arise from a mixture of distributions, each corresponding to a cluster. We propose two estimation methods: a two-stage maximum likelihood method and a fully Bayesian method that uses Markov chain Monte Carlo sampling. The former is quicker and simpler, but the latter performs better. We also propose a Bayesian way of determining the number of clusters that are present by using approximate conditional Bayes factors. Our model represents transitivity, homophily by attributes and clustering simultaneously and does not require the number of clusters to be known. The model makes it easy to simulate realistic networks with clustering, which are potentially useful as inputs to models of more complex systems of which the network is part, such as epidemic models of infectious disease. We apply the model to two networks of social relations. A free software package in the R statistical language, latentnet, is available to analyse data by using the model. 相似文献

This paper discusses recovery of information regarding logistic regression parameters in cases when maximum likelihood estimates of some parameters are infinite. An algorithm for detecting such cases and characterizing the divergence of the parameter estimates is presented. A method for fitting the remaining parameters is also presented . All of these methods rely only on sufficient statistics rather than less aggregated quantities, as required for inference according to the method of Kolassa & Tanner (1994). These results are applied to approximate conditional inference via saddlepoint methods. Specifically, the double saddlepoint method of Skovgaard (1987) is adapted to the case when the solution to the saddlepoint equations exists as a point at infinity 相似文献
