Physical activity and public health recommendations now emphasize the creation of activity-friendly neighborhoods. Mixed land use in a neighborhood is important in this regard, as it reflects the availability of destinations to which residents can walk or ride bicycles, and thus is likely to contribute to residents’ active lifestyles that in turn will influence their overall health. Relationships between land use mix (LUM) and physical activity have not been apparent in some studies, which may be because geographical scale and the specificity of hypothesized environment–behavior associations are not taken into account. We compared the strength of association of four Geographic Information Systems-derived LUM measures with walking for transport and perceived proximity to destinations. We assessed physical activity behaviors of 2,506 adults in 154 Census Collection Districts (CCDs) in Adelaide, Australia, for which ‘‘original’’ LUM measures were calculated, and then refined by either: accounting for the geographic scale of measurement; including only the most-relevant land uses; or, both. The refined (but not the ‘‘original’’) LUM measures had significant associations with the frequency of walking for transport (p < 0.05) and area-corrected measures had significant associations with the duration of walking for transport. All LUM measures had significant associations with perceived proximity to destinations, but stronger associations were seen when using the refined measures compared with the original LUM. Identifying the LUM attributes most strongly associated with walking for transport is a priority and can inform environmental and policy initiatives that are needed to promote health-enhancing physical activity.

Background: Placements as a form of Work Integrated Learning are widely recognised for the positive impact they have on improving student employability and work readiness. Students can maximise strengths, improve areas of weakness, and develop a strong understanding of the requirements of their chosen field within the confines of a well monitored and rich learning environment. Assessment Centres (ACs) are commonly used in corporate settings for recruitment, selection and more recently to provide developmental feedback to participants. Based on a recent literature review, the present the present project evaluates the application of AC methodology as a developmental tool within the placement milieu. The review, which is also included the current conference proceedings details the benefits of utilising the AC process forming the impetus for the present pilot (Sturre; von Treuer & Keele 2010).
Aims: The primary aim of the paper was to evaluate the application of AC methodology as a tool for measuring and subsequently enhancing professional competencies in a sample of postgraduate students in organisational psychology (n=15).
Method: A longitudinal design was utilised with numerous evaluation points from placement stakeholders. This paper presents the first wave of findings. Students undertook a range of activities, including an in-tray exercise, role play, written report, leaderless group discussion and a personality assessment. Comprehensive feedback was provided by organisational psychologists who also fulfil the role of placement co-ordinators. With the assistance of Placement Co-ordinators, students prepared development plans relating to the competencies identified as requiring development. These plans were to be addressed and progress monitored during consecutive placements.
Results: Initial perceptions gathered from students regarding the AC process were very encouraging. Performance
evaluations collected to date, as measured by behaviourally based ratings scales completed by the students themselves and their workplace supervisors illustrate the positive effect of this methodology. The rigour and comprehensive techniques offered by the methodology enabled students to focus on and improve areas identified for development.
Conclusions: It is important to note that the present design formed a pilot study and as mentioned was undertaken with a limited sample. Future implementation is planned with larger samples, enabling a more comprehensive analysis of the methodology. Nevertheless, the methodology appears to provide a much needed strategy for the assessment and ongoing development of students prior to and during work placements. The application provides early intervention enabling students to address development needs with input from both university and organisational stakeholders based on an established, standardised process.

Objective: To describe the pattern of alcohol consumption and associated physical and lifestyle characteristics in a population-based sample of Australian men.
Method: A community-based age-stratifi ed random sample of 1420 men (median age 56 years, range 20 – 93) participating in the Geelong Osteoporosis Study, an epidemiological study set in south-eastern Australia. Daily alcohol intake was ascertained from a detailed food frequency questionnaire and categorized according to the Australian National Health and Medical Research Council 2009 guidelines (non-drinkers, greater than zero but ≤ 2 drinks per day, > 2 drinks per day), with a standard drink equivalent to 10 g of ethanol. Anthropometry was measured and lifestyle factors self-reported. Body composition was determined using dual energy absorptiometry. Socio-economic status was categorized according to the Australian Bureau of Statistics data. Results were age standardized to the Australian male population figures.
Results: The median daily ethanol consumption was 12 g (IQR 2 – 29) per day with a range of 0 – 117 g/day. The age-standardized proportion of non-drinkers was 8.7%, 51.5% consumed up to two drinks per day ( ≤ 20 g ethanol/day), and 39.9% exceeded 2 standard drinks per day ( > 20 g ethanol/day). Alcohol consumption was positively associated with cigarette smoking, weight, higher SES and inversely with age and physical activity.
Conclusions: Approximately, 40% of Australian men consume alcohol at levels in excess of current recommendations, which in combination with other risk factors may adversely impact upon health.

Aims: Sex on premises venues (SOPV) have been given considerable attention, in particular when exploring the relationship between SOPV attendance and risk behaviours such as drug use and unsafe sex. Little attention has been given to the perspectives of those who work in these venues.

Methods: Semi-structured interviews were conducted with staff recruited from four SOPV in Sydney, Australia. Content analysis was performed to identify common themes.

Findings: Several themes emerged from the staff interviews. These themes concentrated on particular drugs of concern; interventions in place to deal with substance use and those under the influence; and that drug use among SOP patrons occurred at venues prior to attending SOPV.

Conclusions: Interviews with SOP workers showed that these venues face unique challenges that may not be encountered by other settings. SOPV staff has a detailed understanding of their clientele and their perspectives may be important not only when informing trends in substance use but also the development and distribution of harm reduction materials.

Introduction and Aims. Considerable concern has been raised about associations between ecstasy use and mental health. Studies of ecstasy users typically investigate varying levels of lifetime use of ecstasy, and often fail to account for other drug use and sociodemographic characteristics of participants, which may explain mixed findings. The current study aimed to examine the relationship between patterns of recent (last six months) ecstasy use and psychological distress among current, regular ecstasy users, controlling for sociodemographic risk factors and patterns of other drug use.

Design and Methods. Data were collected from regular ecstasy users (n = 752) recruited from each capital city in Australia as part of the Ecstasy and related Drugs Reporting System (EDRS). Psychological distress was assessed using the Kessler Psychological Distress Scale (K10). Data were analysed using multinomial logistic regression.

Results. Seven per cent of the sample scored in the ‘high’ distress category and 55% in the ‘medium’ distress category. Patterns of ecstasy use were not independently associated with psychological distress. The strongest predictors of distress were female sex, lower education, unemployment, ‘binge’ drug use including ecstasy (use for >48 h without sleep), frequent cannabis use and daily tobacco use.

Discussion and Conclusions. Regular ecstasy users have elevated levels of psychological distress compared with the general population; however, ecstasy use per se was not independently related to such distress. Other factors, including sociodemographic characteristics and other drug use patterns, appear to be more important. These findings highlight the importance of targeting patterns of polydrug use in order to reduce drug-related harm among regular ecstasy users

Aims:This paper examines the epidemiology of ecstasy use and harm in Australia using multiple data sources.

Design: The data included (1) Australian Customs Service 3,4-methylenedioxymethamphetamine (MDMA) detections; (2) the National Drug Strategy Household and Australian Secondary Student Alcohol and Drug Surveys; (3) data from Australia's ecstasy and Related Drugs Reporting System; (4) the number of recorded police incidents for ecstasy possession and distribution collated by the N.S.W. Bureau of Crime Statistics and Research; (5) the number of calls to the Alcohol and Drug Information Service and Family Drug Support relating to ecstasy; (6) the Alcohol and Other Drug Treatment Services National Minimum Dataset on number of treatment episodes for ecstasy, and (7) N.S.W. Division of Analytical Laboratories toxicology data on number of deaths where MDMA was detected.

Findings: Recent ecstasy use among adults in the general population has increased, whereas among secondary students it has remained low and stable. The patterns of ecstasy consumption among regular ecstasy users have changed over time. Polydrug use and use for extended periods of time (>48 h) remain common among this group. Frequent ecstasy use is associated with a range of risk behaviours and other problems, which tend to be attributed to a number of drugs along with ecstasy. Few ecstasy users present for treatment for problems related to their ecstasy consumption.

Conclusions: Messages and interventions to reduce the risks associated with polydrug use and patterns of extended periods of use are clearly warranted. These messages should be delivered outside of traditional health care settings, as few of these users are engaged with such services.

Given the current state of play with respect to literacy 'crises' in Western democracies, this article revisits the 'language games' that often inform these concerns, examining their rules and who benefits from them. It argues that to focus narrowly on the technical aspects of language, as the current emphasis does, misses the point of what is at stake for students: those who advocates claim to want to help. Drawing on twenty semi-structured interviews and observations of teachers in primary and secondary schools within Queensland (Australia), the article outlines four perspectives on language use and how these variously position students as literate and illiterate. It concludes that we now need a different game plan to address students' use of language, one that provokes a stance and praxis in keeping with a more inclusive politics and which provides real challenges to broader social constraints.
