Abstract. Avalanche hazard assessment requires a very precise estimation of the release area, which still depends, to a large extent, on expert judgement of avalanche specialists. Therefore, a new algorithm for automated identification of potential avalanche release areas was developed. It overcomes some of the limitations of previous tools, which are currently not often applied in hazard mitigation practice. By introducing a multi-scale roughness parameter, fine-scale topography and its attenuation under snow influence is captured. This allows the assessment of snow influence on terrain morphology and, consequently, potential release area size and location. The integration of a wind shelter index enables the user to define release area scenarios as a function of the prevailing wind direction or single storm events. A case study illustrates the practical usefulness of this approach for the definition of release area scenarios under varying snow cover and wind conditions. A validation with historical data demonstrated an improved estimation of avalanche release areas. Our method outperforms a slope-based approach, in particular for more frequent avalanches; however, the application of the algorithm as a forecasting tool remains limited, as snowpack stability is not integrated. Future research activity should therefore focus on the coupling of the algorithm with snowpack conditions.

Victoria Police statistics show that, since the late 1980s, there has been a significant increase in reported rapes in that State. One interpretation of this trend is that there has been an increase in the underlying incidence of sexual violence in the community. An alternative explanation is that rape victims have become more willing to report to the police, in response to factors such as improved provision of support services to sexual assault victims, reforms to substantive and procedural law, and changes in police attitudes and procedures. In order to test these competing interpretations data were collected and analysed on the characteristics of rapes reported to the Victoria Police in the late 1980s/early 1990s. This analysis showed that: (1) most of the additional offences reported in the early 1990s were allegations of rapes committed by family members, spouses and other intimates; and (2) an increasing number of reports related to offences which had been committed at least one year prior to a report being made to the police. It is argued that these changing patterns are co nsistent with a significant increase in the reporting rate for rape. More generally, the research reported in this paper highlights the limitations of reported crime statistics as measures of the level of social violence, and points to the need for crime researchers to develop alternative methodologies for measuring and interpreting trends.

The establishment of integrated responses to family violence represents a significant implementation challenge for locally‐based networks. This research reports on the experiences of integrated family violence committees in Victoria, and the features of their governance associated with perceived effectiveness in committee functioning. There were consistent regional differences in the perceived effectiveness of committees. The main challenge for effective service integration was establishing and maintaining effective partnerships. There were substantial differences in the capacities of the committees to meet the challenges of integration, and the research points to the need for a stronger guidance and support role by central agencies.

The Family Violence Reform strategy in Victoria is one of a number of contemporary government initiatives that have been framed within a whole of government model of policy reform. This article shows how the principles and processes of the whole of government approach were applied to the social problem of family violence. We examine the reasoning behind the adoption of this approach, what it was intended to achieve, the processes and activities that took place and stakeholders' views about the outcomes and impact of this approach. The choice of a whole of government strategy reflected the need to address philosophical and organisational cultural differences about family violence and responses to it. Key elements were: the demonstrated commitment to reform and leadership provided by ministers, agency heads and senior managers; the involvement of community sector representatives; and the role of the Department of Planning and Community Development (DPCD).

Current evidence about the impact of specialized sex offender treatment on reoffending remains inconsistent, drawing attention to the need to focus more on those program characteristics that potentially moderate outcome. This review considers current professional perspectives and evidence on two defining aspects of treatment: its intensity and timing. It is concluded that insufficient evidence currently exists to articulate best practice in this area and there is a pressing need to collect empirical evidence about the effectiveness of different intensity treatments offered at different stages of sentence.

Youth justice settings should provide safe, therapeutic environments, tailored to young people's needs. Current custodial models rarely meet these aims, mainly because a focus on security tends to outweigh an emphasis on care, diminishing rather than encouraging young people's positive development. This article reports on a three-year evaluation of youth justice reforms in the Netherlands, including small-scale, community-embedded facilities with an emphasis on relational security. We outline key operational elements and conditions for implementation of these facilities to provide guidance for youth justice professionals, and for managers and policymakers seeking to promote political and financial investments in effective youth justice strategies.
