Surfing the crime net : policing, crime prevention and community safety in Australia

There can be no doubt that the Internet offers the possibility of increasing access to a range of sources of available information in a timely manner. This is particularly so as we increasingly seek to engage with information from outside our jurisdictional boundaries. While this hints at the effects of globalisation, it is also meant to be suggestive of the practical realities involved in researching (or simply following) developments occurring within emergent federal structures (for instance the European Union) or longer-standing federations such as the United States and Australia. Of course, a department or agency having a homepage and various links is only the start of the process of making information accessible. As will be indicated below, there remain significant limitations in the electronic material available from many agencies. Fortunately, there are also a number of organisations that enable the researcher to access original data and research publications.

What do we know about preventing drug-related harm through social developmental intervention with children and young people

This chapter examines the evidence for the effectiveness of interventions aiming to reduce drug-related harm by improving conditions for healthy develeopment in the earliest years through adolescence. Of the interventions beginning prior to birth, there is efficacy evidence that family home visitation is a feasible strategy for implementation with disadvataged families and can reduce risk factors for early developmental deficits and thereby improve childhood development outcomes. There is efficacy evidence for strategies such as parent education and school preparation through the pre-school age period. Some of the strongest evidence for efficacy in reducing developmental pathways to drug-related harm comes from interventions delivered through the early school years to improve educational environments. Of the interventions targeting the high school age period, school drug education has been the most commonly evaluated. The evidence suggests that short term reduction in both drug use and progression to frequent drug use may be achievable through this strategy, but the prospects for longer-term and population-level behaviour change is still unclear. In overview, a range of prevention strategies have been developed and evaluated. Most of the exisiting evidence is restricted to efficacy studies and there are future challenges to progress evaluation through to studies of effectiveness. In general, prevention programmes appear more successful where they maintain intervention activities over a number of years and incorporate more than one strategy. Much of the existing research has been based in North America and evaluates discrete programmes. Future research should test effects in other countries, in different social contexts and seek to better understand the interrelated effects of combining interventions within the community. Developmental prevention programmes target different age periods and social settings, hence communities have the challenge of coordinating a mixture of programmes that address the local conditions that adversely influence child and youth development. There are opportunities in this work to coordinate prevention activities using funding from different jurisdictions (e.g., crime prevention, health promotion, mental health, education, substance abuse prevention).

'Dig in' to social capital : community gardens as mechanisms for growing urban social connectedness

This article reports on research undertaken with members of a Melbourne urban community garden to explore the extent to which such a natural amenity provides opportunities for enhancing social capital. It is apparent even from this small qualitative study that membership of 'Dig In' community garden offers many benefits to its members. These benefits include increased social cohesion (the sharing of values enabling identification of common aims and the sharing of codes of behaviour governing relationships), social support (having people to turn to in times of crisis) and social connections (the development of social bonds and networks). However, the study indicates that, at least in the early stages of development, such benefits do not necessarily extend beyond the garden setting. This raises a question about the time required to develop high levels of social capital, and points to the need for further research into 'time' and 'space' aspects of community gardens.

An observational assessment of physical activity levels and social behaviour during elementary school recess

Objective: The purpose of the present study was to assess children’s physical activity, social play behaviour, activity type and social interactions during elementary school recess using a pre-validated systematic observation system.

Design: Cross-sectional.

Setting: Two elementary schools located in Merseyside, England.

Method: Fifty-six elementary school children (27 boys, 29 girls) were systematically observed during recess over a three-month period using a standardized physical activity observation instrument.

Results: The results revealed the boys were engaged in significantly higher levels of physical activity during recess than girls. The boys were also involved in more sport-specific activities and participated in larger group sizes. Positive associations between physical activity and availability of equipment during recess were also reported.

Conclusion: This study has confirmed recess as a valuable opportunity for elementary school children to increase their levels of physical activity. However, further studies with larger sample sizes need to identify and explore the relationship between physical activity (PA) and availability of equipment.

The pursuit of exclusion through zonal banning

In recent years, a growing emphasis has been placed on the use of zonal banning to address violence and anti-social behaviour associated with alcohol consumption. While we recognise the longer historical links between territory and crime, this article focuses on recent efforts to govern territory through new zonal regulations. Recent processes in Australia involve the conflation criminal law principles with processes of managing order in and around private spaces through new administrative approaches to alcohol-related law enforcement. The article outlines the nature of sub-sovereign ‘police laws’ and the extent to which they have been used based on Victorian data. We conclude by suggesting these developments need ongoing critical scrutiny given evidence of the ongoing expansion of proprietary-based principles in the management of urban disorder, and the potential for these developments to promote the increased use of surveillance technologies to exclude undesirable populations from the nighttime economies of Australian cities.

In defence of parole : why parole is essential to community safety

This article discusses recent moves to make parole harder to obtain for prisoners serving sentences, and explains why this is disastrous and counter-productive to public safety

Effect of mood, social connectivity and age in online depression community via topic and linguistic analysis

Depression afflicts one in four people during their lives. Several studies have shown that for the isolated and mentally ill, the Web and social media provide effective platforms for supports and treatments as well as to acquire scientific, clinical understanding of this mental condition. More and more individuals affected by depression join online communities to seek for information, express themselves, share their concerns and look for supports [12]. For the first time, we collect and study a large online depression community of more than 12,000 active members from Live Journal. We examine the effect of mood, social connectivity and age on the online messages authored by members in an online depression community. The posts are considered in two aspects: what is written (topic) and how it is written (language style). We use statistical and machine learning methods to discriminate the posts made by bloggers in low versus high valence mood, in different age categories and in different degrees of social connectivity. Using statistical tests, language styles are found to be significantly different between low and high valence cohorts, whilst topics are significantly different between people whose different degrees of social connectivity. High performance is achieved for low versus high valence post classification using writing style as features. The finding suggests the potential of using social media in depression screening, especially in online setting.

Social development measures associated with problem behaviours and weight status in Australian adolescents

During the adolescent years, substance use, anti-social behaviours and overweight/obesity are amongst the major public health concerns. We investigate if risk and protective factors associated with adolescent problem behaviours and substance use are also associated with weight status in young Australian adolescents. Data comes from the 2006 Healthy Neighbourhoods study, a cross-sectional survey of students attending primary (grade 6, mean age 11) and secondary (grade 8, mean age 12) schools in 30 communities across Australia. Adolescents were classified as not overweight, overweight or obese according to international definitions. Logistic and linear regression analyses, adjusted for age, gender and socio-economic disadvantage quartile, were used to quantify associations between weight status (or BMI z-score) and the cumulative number of problem behaviour risk and protective factors. Prevalence of overweight and obesity was 22.6 % (95 % confidence interval (CI), 21.2–24.0 %) and 7.2 % (CI, 6.3–8.3 %). Average number of risk and protective factors present was 4.0 (CI, 3.7–4.2) and 6.2 (CI, 6.1–6.3). Independently, total number of risk factors present was positively associated with likelihood of overweight and obesity, while number of protective factors present was inversely associated with the likelihood of being above a healthy weight. When both risk and protective factors were included in a regression model, only risk factors were associated with the likelihood of being overweight or obese. Average BMI z-score increased by 0.03 units with each additional risk factor present. Prevention programmes targeting developmental risk and protective factors in adolescents that reduce substance use and problem behaviours may also benefit physical health.
