Alcohol: No ordinary commodity research and public policy

From a public health perspective, alcohol is a major contributor to morbidity and mortality. This book describes recent advances in alcohol research which have direct relevance for the development of effective alcohol policies at the local, national and international levels. The central purpose of the book is to empower those responsible for public health and social welfare.

Making licensed venues safer for patrons: what environmental factors should be the focus of interventions?

The Queensland Safety Action Projects operationalized a problem-focused responsive regulatory model in order to make nightclubs and other venues safer. A problem-focused approach requires a careful analysis of the total environment of licensed venues, including drinking and its controls but also the social and physical environments, patron mix and management practices. We present new analyses of observational data collected in 1994 and 1996 in the north Queensland cities of Cairns, Townsville and Mackay. Major reductions in aggression and violence were observed, as well as improvements in many aspects of the venue environment and management practices. We do not argue in this paper that the interventions caused the environmental and management changes, although we believe this to be true. Rather, our assumption is that whatever caused them, some of the environmental and management changes were critical to the reductions in aggression. Regression techniques were used to identify those factors that best explained the declines in aggression. For reduced physical violence four key predictors were identified: improved comfort, availability of public transport, less overt sexual activity and fewer highly drunk men. For reduced non-physical aggression, four key predictors were: fewer Pacific Islander patrons, less male swearing, fewer intoxicated patrons requiring that management be called and more chairs with armrests. The analyses are consistent with the argument that the control of drinking is necessary but not sufficient to reduce aggression and violence.

Repeat Burglary Victimisation: spatial and temporal patterns

To date there has been little Australian research on repeat victimisation. This is a study of repeat burglary in an area of Brisbane using police calls for service data. We demonstrate: (a) the prevalence of residential repeat victim addresses (‘hot dot’) is of a similar magnitude to that found in studies in the United Kingdom; (b) the time distributions of revictimisation are identical with those found in studies in the UK and elsewhere; (c) ‘hot spots’ (small areas with high crime density) can be identified by statistical analyses of spatial concentrations of incidents; (d) unstable hot spots tend to be temporary aggregations of hot dots, whereas stable hot spots seem to reflect more the social and physical characteristics of certain localities; and (e) the overall incidence of burglary could be reduced by at least 25 per cent if all repeat victimisation could be eliminated. There are a number of areas where concepts and techniques for repeat victim research could potentially be strengthened: (a) clarifying the connections between hot dots and hot spots, particularly through exploration of the concept of a ‘near repeat address’; (b) applying survival analysis to the data on the time periods between victimisations; and (c) using moving average techniques to examine changes in the spatial distributions of burglary over time.

Risk and Resilience: Crime and Violence Prevention in Aboriginal Communities

Developmental prevention involves the manipulation of multiple risk and protective factors early in developmental pathways that lead to offending, often at transition points between life phases. The emphasis is not just on individuals but also their social contexts. Risk and protective factors for crime and violence in Aboriginal communities include such standard factors as child abuse, school failure and supportive family environments, but additional factors arise from unique aspects of Aboriginal history, culture and social structure. This paper draws on existing literature, interviews with urban Aboriginal community workers, and data from the Sibling Study to delineate those interrelated risk factors (forced removals, dependence, institutionalised racism, cultural features and substance use) and the equally interrelated protective factors (cultural resilience, personal controls and family control measures). These are ‘meta factors’ that provide a lens through which the standard lists can be interpreted, and are a starting point for the understanding of indigenous developmental pathways.

Very young adolescents and alcohol : evidence of a unique susceptibility to peer alcohol use

AIM The aim of this study is to examine the susceptibility of very young adolescents (10-12 years of age) to peer alcohol-related influences, compared to older adolescents (13-14 years of age). METHODS The analysis sample consisted of 7064 adolescents in grade 6 (modal age 11) or grade 8 (modal age 13) from 231 schools in 30 communities across three Australian States. Key measures were adolescent reports of alcohol use (past 30 days) and the number of peers who consume alcohol without their parents awareness. Control variables included parent alcohol use, family relationship quality, pubertal advancement, school connectedness, sensation seeking, depression, length of time in high school, as well as age, gender, father/mother education, and language spoken at home. A multi-level model of alcohol use was used to account for school-level clustering on the dependent variable. RESULTS For both groups, the number of peers who consumed alcohol was associated with alcohol use, but Grade 6 students showed a unique susceptibility to peripheral involvement with peer drinking networks (having one friend who consumed alcohol). CONCLUSION The results point to the importance of monitoring and responding to comparatively minor shifts in the proportion of peers who use alcohol, particularly among very young adolescents.

DRINK-DRIVING LAW ENFORCEMENT AND THE LEGAL BLOOD ALCOHOL LIMIT IN NEW SOUTH WALES

This paper reports the results of a preliminary analysis of daily fatal crashes in New South Wales, Australia, between July 1975 and December 1986. The analysis unexpectedly uncovered a small but statistically significant decline in crashes coinciding with the introduction of a law lowering the legal blood alcohol concentration (BAC) from .08 to .05 g%. The original aim of the analysis was to develop for a larger study appropriate log-linear techniques to assess the impact of a range of government initiatives, including laws aimed at the drinking driver: increased penalties, the .05 law, and random breath testing (RBT). The analysis showed that RBT immediately reduced fatal crashes by 19.5% overall and by 30% during holiday periods, and that the .05 law, introduced two years before RBT, apparently reduced fatal crashes by 13% on Saturdays. There was no significant effect of the .05 law on any other day of the week, and there was no clear evidence that any other initiative had a statistically significant effect on accidents. Although the apparent impact of the .05 law was small, it is surprising that any effect was discernible, since the law was not extensively advertised and police enforcement was no more intense than is usual over Christmas. However, any effects of the .05 law may not have been sustained if RBT had not been introduced two years later.

Reducing Violence in Licensed Venues Through Community Safety Action Projects: The Queensland Experience

Community-based safety action projects, replications of the model developed in Surfers Paradise designed to reduce violence and disorder in licensed environments in city entertainment areas, were implemented in three diverse North Queensland cities (Cairns, Townsville and Mackay). The change model is based on prior experience with community interventions, the theory of situational crime prevention, and the theory of responsive regulation. The interventions took place in each city during 1995 and early 1996. The results are based on unobtrusive direct observations by patron-observers of aggression, drinking, and management practices in licensed venues in September 1994 and October 1996. There was a decline of 56% in all aggressive and violent incidents, and a decline of at least 75% in physical assaults, but conclusions concerning direct causality cannot be drawn. These declines, which did not differ significantly between cities, coincided with marked improvements in host responsibility practices and a decline in male drunkenness.

Environmental quality and the well-being of children

There are many reasons for believing that the environment exerts an influence (directly or indirectly) on the wellbeing of children and families. However, while clear evidence is available that low socioeconomic status is associated with lower than average levels of wellbeing, especially among adults, the evidence linking the social and emotional adjustment of children with the quality of the environment is patchy and equivocal. In this paper we focus on three levels of the family environment: the street, the home and the neighborhood. Neighborhood quality was measured by the Vinson-Homel social problems index, street-type as residential or commercial/retail, and housing quality in terms of upkeep, floor occupied, availability of playspace and occupancy type. The research hypothesis was that after allowing for community selection processes children living in lower quality environments would be less satisfied with various areas of their lives, would experience more negative emotions, and would have more restricted and less positive friendship patterns. The sample comprised 321 families which included a 9–11 year old child, drawn from 18 neighborhoods of Sydney. Neighborhood social problem score and street-type, and some aspects of housing, predicted emotional and social adjustment. Before and after controls for family composition, social class and culture, children living in commercial streets, particularly in inner-city areas, stood out from all others in their feelings of loneliness, dislike of other children and feelings of rejection, worry, fear, anger and unhappiness. Children living in high social problems areas showed a pattern of social constriction rather than maladjustment. These results suggest not simply the influence of social class but genuine community socialization effects. Possible sources of, and mechanisms for, these effects are suggested.

Alcohol : No Ordinary Commodity – a summary of the second edition

This article summarizes the contents of Alcohol: No Ordinary Commodity (2nd edn). The first part of the book describes why alcohol is not an ordinary commodity, and reviews epidemiological data that establish alcohol as a major contributor to the global burden of disease, disability and death in high-, middle- and low-income countries. This section also documents how international beer and spirits production has been consolidated recently by a small number of global corporations that are expanding their operations in Eastern Europe, Asia, Africa and Latin America. In the second part of the book, the scientific evidence for strategies and interventions that can prevent or minimize alcohol-related harm is reviewed critically in seven key areas: pricing and taxation, regulating the physical availability of alcohol, modifying the drinking context, drink-driving countermeasures, restrictions on marketing, education and persuasion strategies, and treatment and early intervention services. Finally, the book addresses the policy-making process at the local, national and international levels and provides ratings of the effectiveness of strategies and interventions from a public health perspective. Overall, the strongest, most cost-effective strategies include taxation that increases prices, restrictions on the physical availability of alcohol, drink-driving countermeasures, brief interventions with at risk drinkers and treatment of drinkers with alcohol dependence.

How Do School Connectedness and Attachment to Parents Interrelate in Predicting Adolescent Depressive Symptoms

In this study, we tested whether school connectedness mediated or moderated the effect of parental attachment on adolescent depressive symptoms. A sample of 153 secondary school students ranging from 8th to 12th grade were assessed using measures of parental attachment, school connectedness, and depressive symptoms. Independently, parental attachment and school connectedness accounted for 28% and 49% of the variance in depressive symptoms respectively, whereas collectively they accounted for 53% of the variance. School connectedness only partially mediated the relationship between parental attachment and depressive symptoms, and there was no significant moderation effect.
