An analysis of police officers decisions about whether to refer cases of child abuse for prosecution

In many jurisdictions, police officers are responsible for deciding whether cases of child abuse are referred for potential prosecution. Such discretion justifies the need to scrutinise these professionals' decisions to determine if they are consistent with the scientific eyewitness memory literature. Prior research has shown that interviewer questioning is one of the most critical factors impacting the reliability of child witness statements. Hence, we asked: 'To what degree do officers' consider the quality of interviewer questions when making case authorisation decisions?'. In order to answer this question, we conducted a thematic analysis to identify issues referred to in a sample of documented police correspondence (n=33) about potential prosecution of child abuse cases. Two key themes emerged: the existence of corroborative evidence and whether the suspect denied the allegations. Questioning technique, however, was not considered. All but one decision that referred to interview process focused on the presentation of the witness, even though the witness interviews (as a whole) did not adhere to recommended best-practice guidelines. The implications of these findings are discussed.

'Traffic-light' nutrition labelling and 'junk-food' tax : a modelled comparison of cost-effectiveness for obesity prevention

Introduction: Cost-effectiveness analyses are important tools in efforts to prioritise interventions for obesity prevention.
Modelling facilitates evaluation of multiple scenarios with varying assumptions. This study compares the cost-effectiveness of
conservative scenarios for two commonly proposed policy-based interventions: front-of-pack ‘traffic-light’ nutrition labelling
(traffic-light labelling) and a tax on unhealthy foods (‘junk-food’ tax).
Methods: For traffic-light labelling, estimates of changes in energy intake were based on an assumed 10% shift in consumption
towards healthier options in four food categories (breakfast cereals, pastries, sausages and preprepared meals) in 10% of adults. For the ‘junk-food’ tax, price elasticities were used to estimate a change in energy intake in response to a 10% price increase in seven food categories (including soft drinks, confectionery and snack foods). Changes in population weight and body mass index by sex were then estimated based on these changes in population energy intake, along with subsequent impacts on disability-adjusted life years (DALYs). Associated resource use was measured and costed using pathway analysis, based on a health sector perspective (with some industry costs included). Costs and health outcomes were discounted at 3%. The cost-effectiveness of each intervention was modelled for the 2003 Australian adult population.
Results: Both interventions resulted in reduced mean weight (traffic-light labelling: 1.3 kg (95% uncertainty interval (UI): 1.2;
1.4); ‘junk-food’ tax: 1.6 kg (95% UI: 1.5; 1.7)); and DALYs averted (traffic-light labelling: 45 100 (95% UI: 37 700; 60 100);
‘junk-food’ tax: 559 000 (95% UI: 459 500; 676 000)). Cost outlays were AUD81 million (95% UI: 44.7; 108.0) for traffic-light
labelling and AUD18 million (95% UI: 14.4; 21.6) for ‘junk-food’ tax. Cost-effectiveness analysis showed both interventions were
‘dominant’ (effective and cost-saving).
Conclusion: Policy-based population-wide interventions such as traffic-light nutrition labelling and taxes on unhealthy foods are
likely to offer excellent ‘value for money’ as obesity prevention measures.

Psychological profiling of Tasmanian police officers using the COPS

This thesis examined selection processes for police candidates, and the impact of police work on well-being. Results revealed that policing impacts negatively on psychological well-being over time, and that many aspects of the stereotypic 'police personality' are not a result of selection processes, but develop over time in the role.

The perennial problem of police gratuities : public concerns, political optics, and an accountability ethos

Despite the perennial nature of the problem of gratuities in considerations of police ethics, many prior analyses of this issue have rested on anecdotal, piecemeal or hypothetical considerations.. This paper draws on a unique sample of actual complaint cases involving gratuities, providing evidence of a range of public concerns about the problem. Gratuities are analysed and contextualised by reference to the concept of conflict of interest, which draws attention to the potential for the performance of public duty to be tainted in fact or appearance. In either case, public trust in the integrity of the police is damaged, giving rise to "political optics" as a key problem with gratuities.  The paper argues that an accountability ethos must be developed to promote active responsibility and a preparedness to prioritise the public interest in policing.

An automatic application signature construction system for unknown traffic

Identifying applications and classifying network traffic flows according to their source applications are critical for a broad range of network activities. Such a decision can be based on packet header fields, packet payload content, statistical characteristics of traffic and communication patterns of network hosts. However, most present techniques rely on some sort of apriori knowledge, which means they require labor-intensive preprocessing before running and cannot deal with previously unknown applications. In this paper, we propose a traffic classification system based on application signatures, with a novel approach to fully automate the process of deriving signatures from unidentified traffic. The key idea is to integrate statistics-based flow clustering with payload-based signature matching method, so as to eliminate the requirement of pre-labeled training data sets. We evaluate the efficiency of our approach using real-world traffic trace, and the results indicate that signature classifiers built from clustered data and pre-labeled data are able to achieve similar high accuracy better than 99%.

State police in a state of change: remaking the entrepreneurial officer

We are currently at a point in time in Australia where questions concerning how to govern police have never been more pressing or more fluid. Systemic corruption has been identified in several states; a range of new accountability mechanisms have been established internal and external to police and in Victoria police corruption has been linked with a violent 'gangland war'. This thesis locates these contemporary developments within a broader analysis of the historical circumstances shaping the changing techniques for governing state police. More specifically, this thesis engages in a detailed comparative study of the changing techniques of governing police in Queensland and Victoria. The theoretical tools to conduct this analysis are drawn from 'governmentality studies'. This refers to a broad grouping of theoretical scholarship concerned with the changing ideas - or 'political rationalities' - on how to govern some thing or some activity, and the underlying reasoning, justifications and ambitions contained within the practical tools or 'techniques' used to govern. Central to the thesis is an argument that a new politics of policing has emerged recently, one that extends the dyad of the old accountability - 'police powers' and 'external accountability' - to a pluralisation of accountability processes and structures. The thesis argues that governmentality studies offer new insights into ways of analysing the techniques for governing state police, increasingly shaped by the managerialisation of governing and embodying efforts to make police innovative, risk-taking problems-solvers. This is what I refer to as an open-ended normative project for re-making the entrepreneurial officer. However, a detailed examination of the development of governmental techniques for 'making up' the entrepreneurial officer indicates that such a governmental project is not implemented unproblematically. Nonetheless, the thesis concludes that the attempts to remake the entrepreneurial officer through the managerialisation of governing presents distinct possibilities for a new 'politics of policing' that fosters deliberative, reflective police practice within a new framework of police accountabilities

A menace to this realm : the new guard and the New South Wales police, 1931-32

In 1931 and 1932, New South Wales faced civic collapse. During the last months of the Lang government, the semi-fascist New Guard became a serious threat to the state. This article examines the challenge posed by the New Guard to the New South Wales police, and the strategies used by the police to suppress the group. Superintendent W.J. MacKay, the colourful and Machiavellian future commissioner, effectively and ruthlessly exercised police power against the New Guard. This article disputes the dominant historical interpretation of this period, which sees the police as collaborators with a reactionary secret army, the ‘Old Guard’.

Police and Vietnamese-Australian communities in multi-ethnic Melbourne

This paper explores practical solutions to sensitive community policing issues, drawing on an Australian case study of relations between police and Australian-Vietnamese communities. The paper summarizes initial research on the attitudes of Australian-Vietnamese community members and police to one another and to security and crime. Despite three decades of community policing, there is only limited communication flow between Vietnamese-Australian citizens including offenders and victims and police. The question is whether partnership policing can fill the gap. For police, this involves understanding not only ethnic distinctiveness but also intergenerational issues, tensions within cultural groups, and changing complex forms of membership and affiliation.

'Murderous coppers': police, industrial disputes and the 1929 Rothbury shootings

Norman Brown, a coalminer engaged in picketing the Rothbury colliery, was shot dead by police in 1929. The Rothbury incident and the police suppression which followed became part of both union folklore and the personal legend of one police officer, William John MacKay, later New South Wales Police Commissioner. This article probes beneath the layers of myth that surround Rothbury and argues that the initial tragedy was largely the result of police incompetence, and that MacKay’s association with the shooting is deeply ironic. The more measured police actions that followed the shootings were Mackay’s responsibility, however, and they had damaging long-term consequences.

Improving the legal aspects of police interviewing of suspects

The purpose of this paper is to provide some guidance to police interviewers and trainers in relation to improving the legal aspects of police questioning of suspects. The paper is written with reference to Victorian legislation. Sixteen professionals (defence barristers, academics, prosecutors, and detectives), all with extensive knowledge of the law and experience evaluating police interviews with suspects, took part in individual indepth interviews (M ¼ 100 minutes). The aim of the interviews was to discuss the limitations of police interviews with suspects and to provide exemplars of concerns from a set of de-identified transcripts that had been provided to the professionals prior to their interviews with us. Overall, four key limitations were raised: (a) inadequate particularisation of offences, (b) inappropriate phrasing of questions, (c) poor introduction of allegations, and (d) questions that unfairly ask the suspect to comment on the victim’s perspective. These concerns and their practical implications are discussed.
