Can social workers and police be partners when dealing with bikie-gang related domestic violence and sexual assault?

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.     

ON BOOTSTRAP HYPOTHESIS TESTING

We describe methods for constructing bootstrap hypothesis tests, illustrating our approach using analysis of variance. The importance of pivotalness is discussed. Pivotal statistics usually result in improved accuracy of level. We note that hypothesis tests and confidence intervals call for different methods of resampling, so as to ensure that accurate critical point estimates are obtained in the former case even when data fail to comply with the null hypothesis. Our main points are illustrated by a simulation study and application to three real data sets.     

THE RATE OF CONVERGENCE IN THE NORMAL APPROXIMATION FOR THE WILCOXON R-ESTIMATOR

We exploit the fact that the Wilcoxon score R-estimator of the slope in a linear regression model minimises Gini's mean difference of the residuals to obtain a Berry-Esseen rate of convergence result for the Wilcoxon R-estimator.     

Statistical methodology for assessing homology of intronic regions of genes

We consider the problem of statistically evaluating the similarity of DNA intronic regions of genes. Present algorithms are based on matching a sequence of interest with known DNA sequences in a gene bank and are designed primarily to assess homology among exonic regions of genes. Most research focuses on exonic regions because they have a clear biological significance, coding for proteins, and therefore tend to be more conserved in evolution than intronic regions. To investigate whether the intronic features of genes whose expression is highly sensitive to environmental perturbations differ from genes that have a more constant expression, a collection of oncogenes, tumor suppressor genes, and nonregulatory genes involved in energy metabolism are compared. An analysis of the features of these genes' intronic regions result in clustering by regulatory group. In addition, Billingsley's test for Markov structure (1961) suggests that 67% of the intronic regions in this collection of genes show evidence of nonrandom structure, indicating the possibility of a biological function for these regions. The result of Billingsley's test for homology is used as input to a clustering algorithm. The biological significance of this methodology lies in the identification of groups based on the intronic regions from genes of unknown function. With the advent of rapid sequencing techniques, there is a great need for statistical techniques to help identify the purpose of poorly understood portions of genes. These methods can be utilized to assess the functional group to which such a gene might possibly belong.     

Dynamic Pricing to Minimize Maximum Regret

We consider a dynamic pricing problem that involves selling a given inventory of a single product over a short, two‐period selling season. There is insufficient time to replenish inventory during this season, hence sales are made entirely from inventory. The demand for the product is a stochastic, nonincreasing function of price. We assume interval uncertainty for demand, that is, knowledge of upper and lower bounds but not a probability distribution, with no correlation between the two periods. We minimize the maximum total regret over the two periods that results from the pricing decisions. We consider a dynamic model where the decision maker chooses the price for each period contingent on the remaining inventory at the beginning of the period, and a static model where the decision maker chooses the prices for both periods at the beginning of the first period. Both models can be solved by a polynomial time algorithm that solves systems of linear inequalities. Our computational study demonstrates that the prices generated by both our models are insensitive to errors in estimating the demand intervals. Our dynamic model outperforms our static model and two classical approaches that do not use demand probability distributions, when evaluated by maximum regret, average relative regret, variability, and risk measures. Further, our dynamic model generates a total expected revenue which closely approximates that of a maximum expected revenue approach which requires demand probability distributions.     

Abortion Counselling in Britain: Understanding the Controversy

This article reviews literature from a number of disciplines in order to provide an explanation of the political controversy attached to the provision of abortion counselling. It will show how this is an area of health policy debate in which women's reproductive bodies have become a setting for political struggle. The issue of abortion counselling in Britain has undergone a number of discursive shifts in response to political manoeuvring and changing socio‐legal framing of abortion. In particular, the article shows how much of the controversial reframing of abortion counselling was a tactical shift by political actors opposed to abortion per se, and this work is critiqued for not contextualising abortion. The article then focuses on women's abortion experiences and discusses research that shows how women's decision‐making processes, and responses to an abortion, are related to gendered socio‐cultural contexts: the extent to which women having an abortion feel they have transgressed societal norms and values, for example, is likely to affect their abortion experiences. Finally, it is suggested that providing a non‐judgemental context, and challenging negative discourses on abortion, may be the most effective way of minimising the possibility of negative emotions.     

John Porter Lecture: Waves of Protest—Direct Action,Deliberation, and Diffusion

The book Direct Action, Deliberation and Diffusion: Collective Action After the WTO Protests in Seattle argues that the process of diffusion is dependent on social processes in the receiving context. The most important in social movements is an egalitarian and reflexive deliberation among diverse actors. The book traces the direct action tactics associated with the Seattle protests against the World Trade Organization in 1999 and how these spread to activists in Toronto and New York City. It shows how the structure of the political field, racial and class inequalities, identity boundaries, and organizational and conversational dynamics limited deliberation among activists, and thus limited the diffusion of the Seattle tactics. By constraining the spread of the Seattle tactics, this slowed the global justice movement's wave of protest. In this paper, I explore the application of and implications of this model of protest tactic diffusion to the recent Idle No More mobilizations. Le livre Direct Action, Deliberation and Diffusion: Collective Action After the WTO Protests in Seattle fait valoir que le processus de diffusion dépend de processus sociaux dans le contexte de réception. Le plus important pour les movements sociaux est une délibération égalitaire et réflexive entre divers acteurs. Le livre retrace les tactiques d'action directe associés aux manifestations de Seattle contre l’Organisation Mondiale du Commerce en 1999 et comment ils se propagent à des militants de Toronto et de New York. Il montre comment la délibération de la structure des inégalités le domaine politique, raciales et de classe, les limites de l'identité et de la dynamique de l'organisation et de la conversation limitée parmi les militants, et donc limiter la diffusion de la tactique de Seattle. En limitant la propagation de la tactique de Seattle, ce ralentissement de la vague de protestation du mouvement altermondialiste. Dans cet article, j'explore l'application et implications de ce modèle de diffusion protestation de tactique pour les dernières Idle No More mobilisations.     

Estimating the prevalence of adolescent gambling disorders: A quantitative synthesis and guide toward standard gambling nomenclature

This article reviews the extant published and unpublished studies that estimate the prevalence of adolescent gambling problems in North America. The nine nonduplicative studies identified by our literature search included data collected from more than 7700 adolescents from five different regions of the United States and Canada. In addition to comparing the conceptual and methodological differences that exist among these studies, this article employed a meta-analytic strategy to synthesize prevalence estimates from the existing studies. This analysis revealed that within a 95 percent confidence interval, between 9.9% and 14.2% of adolescents are at risk of developing or returning to serious gambling problems. Similarly, between 4.4% and 7.4% of adolescents exhibit seriously adverse compulsive or pathological patterns of gambling activity. Finally, the discussion proposes a generic multi-level classification scheme to reconcile the divergent classification methods and data reporting strategies. This new multi-level approach to reporting gambling prevalence will facilitate interstudy comparisons among existing estimates of gambling prevalence and help to provide a general data reporting system for future research.
