Dealing with alcohol-related harm and the night-time economy

Alcohol-related problems are a major cause of social disorder and illness in Australia. In particular, problems associated with the night-time economies of urban and regional centres cause substantial community concern and are a considerable drain on police, community and health resources. The estimated cost of alcohol to the community is $15.3 billion, including costs associated with crime, violence, patient treatment, loss of productivity and premature deaths in 2004–05 (Collins 2008). Alcohol has also been identified as a factor in around three quarters of assaults and incidents of offensive behaviour on the street (Buss 1995). Previous research has identified several issues that contribute to the levels of short-term harm associated with risky drinking. These include: excessive consumption at licensed premises, consumption in public areas and lack of transport and security in entertainment precincts (Homel et al. 1992; Graham & Homel 2008).

Drinking in licensed venues is another predictor of harm and public disorder. More than half of offences occurring on the street have been associated with licensed premises in Australia (Buss 1995). A complex range of factors increase risky drinking and associated harms on licensed premises including: aspects of patron mix; levels of comfort, boredom, and intoxication; promotions that cause mass intoxication; and the behaviour of security/bouncers (Homel et al. 1992). Violence has also been shown to be perpetuated by poor venue management, lax police surveillance, lack of transport options for patrons, and inappropriate bureaucratic controls and legislation (Homel et al. 1992). This project aims to provide evidence-based knowledge regarding the implementation and impact of innovative local initiatives directed at alcohol-related harms.

The association between alcohol interventions and Dui incidents in Geelong, Victoria

Introduction and aims : Driving under the influence of alcohol is a major public health problem, every year affecting the lives of billions around the world - and not least in Australia. Since 2001, several Traffic Accident Commission (TAC), police, and community interventions have been implemented in Geelong, Australia to curb drink driving. The current paper aims to assess the impact of 13 alcohol interventions on drink-driving rates in the Geelong region of Australia. The interventions comprised seven TAC media campaigns, three Victoria Police operations, two community interventions targeting licensed premises, and the alcohol interlock program.

Method : This study examined two types of Victoria Police frequency data: Driving under the influence (DUI) offences, and roadside preliminary breath testing (PBT) rates. Multiple regressions were carried out to determine if any of the interventions were significantly associated with frequency fluctuations in the data.

Results : Of the 13 alcohol interventions examined, three TAC campaigns and one Victoria Police operation precipitated significant decreases in drink-driving rates, while another three TAC campaigns were associated with significant increases in drink-driving rates. Over one in five (22.5%) had recorded prior DUI offences.

Conclusions : The most promising approach to curbing DUI-rates in Geelong, appear to be through informative media campaigns which show people specific settings where they might become mildly intoxicated without being aware of it, such as TAC’s ‘Education 1’ campaign. However, there remains a worrying level of recidivist drink drivers in Geelong suggesting the need for tailored approaches.

Monitoring the early stage self-assembly of enzyme-assisted peptide hydrogels

The early stages of the self-assembly of peptide hydrogels largely determine their final material properties. Here we discuss experimental methodologies for monitoring the self-assembly kinetics which underpin peptide hydrogel formation. The early stage assembly of an enzyme-catalysed Fmoc-trileucine based self-assembled hydrogel was examined using spectroscopic techniques (circular dichroism, CD, and solution NMR) as well as chromatographic (HPLC) and mechanical (rheology) techniques. Optimal conditions for enzyme-assisted hydrogel formation were identified and the kinetics examined. A lag time associated with the formation and accumulation of the self-assembling peptide monomer was observed and a minimum hydrogelator concentration required for gelation was identified. Subsequent formation of well defined nano-and microscale structures lead to self-supporting hydrogels at a range of substrate and enzyme concentrations. 1H NMR monitoring of the early self-assembly process revealed trends that were well in agreement with those identified using traditional methods (i.e. HPLC, CD, rheology) demonstrating 1H NMR spectroscopy can be used to non-invasively monitor the self-assembly of peptide hydrogels without damaging or perturbing the system.

Acculturation and obesity among migrant populations in high income countries - a systematic review

Background:
There is evidence to suggest that immigrant populations from low or medium-income countries to high income countries show a significant change in obesogenic behaviors in the host society, and that these changes are associated with acculturation. However, the results of studies vary depending on how acculturation is measured. The objective of this study is to systematically review the evidence on the relationship between acculturation - as measured with a standardized acculturation scale - and overweight/obesity among adult migrants from low/middle countries to high income countries.

Methods:

FRAX provides robust fracture prediction regardless of socioeconomic status

The authors investigated the fracture risk assessment tool (FRAX) Canada calibration and discrimination according to income quintile in 51,327 Canadian women, with and without a competing mortality framework. The data shows that, under a competing mortality framework, FRAX provides robust fracture prediction and calibration regardless of socioeconomic status (SES).

The association between sports participation, alcohol use and aggression and violence: a systematic review

Objectives
To review the current research on alcohol-related violence and sports participation.

Methods
The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were used to identify relevant studies for inclusion. A search of six databases (EBSCOhost) was conducted.

Results
A total of 6890 studies was were identified in the initial search. Of these, 11 studies met the inclusion criteria. The majority of the studies were from the US (n = 10) and focused on collegiate athletes (n = 7), adolescents (n = 3), professional/former professional athletes (n = 1).

Conclusion
The reviewed research indicates higher rates of alcohol use and violence in athlete populations when compared against non-athlete populations. Masculinity, violent social identity and antisocial norms connected to certain sports stand out as potential factors that may impact the association between sport and violence in athlete populations.

Merah and Breivik: a mirror effect of a European identity crisis

While the cases of Anders Behring Breivik and Mohamed Merah clearly demonstrate the impact of social networks and the role of the Internet and prison on the radicalization process, the killings in Norway and France in fact expose larger issues that exist within contemporary Europe, including profound identity crises manifesting as Islamist extremism in some quarters and far-right extremism in others. This article discusses the individual pathways towards extremism of Merah and Breivik, the interconnectivity of two extremisms and how these can be understood as mirrored manifestations of an identity crisis in Europe.
