Outcomes were compared over an average of 4.8 years (SD = 29.20 months; range = 15 days to 9.25 years) on 2,407 adult males convicted of sexual offences and discharged from custody between 2010 and 2017. Controlling for risk, age, treatment location, and cultural heritage, those who completed a combination of preparatory programs, rehabilitation and reintegration programs were less likely to reoffend and had significantly better survival rates when they did reoffend, compared to those who did not complete—or partially completed—programs. However, reintegration programs, regardless of involvement with other correctional programming, also demonstrated success in reducing short-term recidivism. Combined, these findings indicate that the composition and sequencing of correctional programming li...

The systematic search identified 20,820 records, yielding eight eligible impact evaluations. Six studies focused on policing and two on the judicial arm of the criminal justice system. No correctional impact evaluations met our inclusion criteria. We qualitatively synthesise the evidence and use an evidence and gap map to visualise the current state of the evaluation evidence. Future research needs to prospectively design and rigorously evaluate evidence-informed interventions that are specifically tailored to CSAM offending.

Just 13 impact evaluation studies (reported in 18 documents) met inclusion criteria. An evidence and gap map was constructed, showing that research to date relates primarily to drug harms, followed by drug crime and drug price, and that there are significant gaps in the impact evaluation literature. The results of this review demonstrate the limited amount of high-quality scientific evidence that can be used to examine the impact of supplier arrest and seizure on a range of drug-related outcomes.

The MPCO is a vehicle that allows police to conduct most station activities from various locations. An important component of this trial was its use of social media to foster engagement with the police. This paper analyses comments on three types of Facebook posts: ‘Blue’s Clues’, which utilised a riddle and prize to encourage the public to visit the MPCO at its crime hot spot deployments; a post on the 31st December, 2014 wishing the community ‘Happy New Year’; and a post asking patrons to complete a survey that gauged the public’s perceptions of police, crime in their community, and the MPCO itself. Results suggest that posts that garner the greatest public engagement via comments are those that invite dialogue and feedback. This paper provides an evidence-based understanding of how police can better engage with the public through social media when evaluating the impact of policing strategies. It concludes with recommendations for future research and police practice.

While models of radicalisation can vary by contexts (Borum, 2015; Christmann, 2012; Desmarais et al., 2017; Koehler 2017; Horgan, 2008; Sarma, 2017), it is broadly defined as the process by which a person adopts extremist views and moves towards committing a violent act (Hardy, 2013; Jensen, Seate, & James, 2018). Radicalisation has been linked with individual and group engagement in terrorist attacks against innocent civilians (Wilner, & Dubouloz, 2010), and individuals entering conflict zones to join formal extremist groups to engage in violent combat (Lindekilde, Bertelsen, & Stohl, 2016). As a result, radicalisation has become a key focus of counterterrorism and violence prevention interventions...

This review is to be considered as a rudimentary starting point in understanding the evidence for the effectiveness of 15 intervention categories put forward by the Dept of Child Safety, Youth & Women. This rapid review summarises the evidence for 15 intervention categories and their impact on the following focal outcomes: (a) family preservation and reunification; (b) child safety intervention or action; (c) child psychosocial outcomes (e.g. stability of living arrangements, mental and physical health, education, employment, involvement in the criminal justice system).

Specifically, this rapid review considers the evaluation evidence for studies that examine the impact of a road policing intervention on the following outcomes:(1) Road safety (e.g. fatalities or injuries);(2) Offence detection (e.g., speeding or traffic violations);(3) Social costs (e.g. traffic congestion);(4) Organisation effects for police personnel and organisations (including costs); and(5) Public trust, confidence, and legitimacy in the police.
