The effect of smoke-free policies on revenue in bars in Tasmania, Australia

Objective: To examine the impact of smoke-free policies on revenue in Tasmanian bars.

Method: Monthly sales turnover from January 2002 to March 2007, provided by the Australian Bureau of Statistics was analysed. There were two outcome measures: (1) the ratio of monthly bar sales turnover in Tasmania to monthly bar sales turnover in four other Australian states, and (2) the ratio of monthly bar turnover to monthly retail turnover in Tasmania. Linear regression was used to assess the impact of the smoke-free policy on expenditure.

Results: The smoke-free policy had no effect on sales turnover.

Conclusion: The smoke-free policy protects hospitality workers and patrons from exposure to secondhand smoke and has had no adverse effect on sales turnover.

The effect of smokefree policies on electronic gaming machine expenditure in Victoria, Australia

Objective: To examine the impact of smoke-free policies in Victorian gambling venues on electronic gaming machine (EGM) expenditure.

Method: Monthly EGM expenditure from July 1998 to December 2005, provided by the Victorian Commission for Gambling Regulation and the Office of the Liquor and Gambling Commissioner in South Australia, was analysed. The outcome measure was the ratio of monthly expenditure for Victoria to monthly expenditure in South Australia. Intervention analysis and autoregressive integrated moving average modelling were used to assess the impact of the smoke-free policy on expenditure.

Results: The smoke-free policy resulted in an abrupt, long-term decrease in the level of EGM expenditure. The mean level of monthly expenditure decreased by approximately 14%.

Conclusion: The smoke-free policy not only protects hospitality workers and patrons from exposure to secondhand smoke but has also had an impact on slowing gambling losses.

The effect of a smoke-free law on restaurant business in South Australia

Background: Despite evidence to the contrary from overseas research, the introduction of smoke-free legislation in South Australia (SA), which required all restaurants to go smoke-free in January 1999, sparked concerns among the hospitality industry about loss of restaurant business. This study aimed to determine whether the law had a detrimental impact on restaurant business in SA.

Methods: Using time series analysis, we compared the ratio of monthly restaurant turnover from restaurants and cafes in SA to (a) total retail turnover in SA (minus restaurants) for the years 1991 to 2001 and (b) Australian restaurant turnover (minus SA, Western Australia and the Australian Capital Territory) for the years 1991–2000.

Results: There was no decline in the ratio of (a) SA restaurant turnover to SA retail turnover or (b) SA restaurant turnover to Australian restaurant turnover.

Conclusion: The introduction of a smoke-free law applying to restaurants in SA did not adversely affect restaurant business in SA.

A new environmental design : sustainable place making in postcolonial Australia

This paper seeks to expand on environmental design understood in purely
instrumentalist terms. It argues that current environmental emergencies in Austlalia and elsewhere are requiring alternative strategies of response, and proposes the terrain of poetic w'ork as offering new insights in the field of sustainability practice. lt draws upon two place-making projects to advance a theory of environmental design that is poetically guided.

Detection and treatment of hypertension in rural Australia

Background: The inequity of cardiac health outcomes between metropolitan and rural areas is well documented. As hypertension is a major cardiovascular risk factor, we need to have a better understanding of how well it is detected and managed rural areas. This study reports on the prevalence, detection and treatment of hypertension in rural Australia.

Method: Three population stratified surveys were undertaken in the Greater Green Triangle. Three thousand three hundred and twenty adults aged 25–74 years were randomly selected, stratified by gender and 10-year age groups. Anthropometric, clinical and self-administered questionnaire data relating to chronic disease risk were collected in accordance with the WHO MONICA protocol. Blood pressure (BP) was measured by trained nurses and the questionnaire collected information on the history of hypertension and medications used for treatment.

Results: Information on BP measurement, medication and awareness was available on 1506 (45%) participants. Study found that one-third of participants had hypertension. Only 54% (95% CI 47–60) of male and 71% (65–77) of female participants with hypertension were aware of their condition. While only half of the participants with hypertension were treated, only half of these treated participants had their hypertension under control. Treatment and control of hypertension was more common in women (60%, 54–67 and 55%, 47–64) compared with men (42%, 36–49 and 35%, 26–44).

Conclusion: Results of our study suggest that detection and treatment of hypertension in rural is suboptimal, particularly in men. If cardiovascular outcomes are to improve in rural Australia, people need to be encouraged to have their blood pressure measured regularly and better systems for the management of hypertension in primary care are needed.

Management of lipids in rural Australia : are the guidelines being followed?

Background: Hypercholesterolaemia is ranked seventh among the major factors contributing to the overall burden of disease in Australia. Guidelines for evidence-based lipid management were released in 2001 and updated in 2005, however little population level data has been published on the current gap between recommended management and actual practice in Australia.

Method: Three population stratified surveys were undertaken in the Greater Green Triangle. Three thousand three hundred and twenty adults aged 25–74 years were randomly selected, stratified by gender and 10-year age groups. Anthropometric, clinical and self-administered questionnaire data relating to cardiovascular disease risk were collected in accordance with the WHO MONICA protocol. Blood samples were collected for lipid profile analysis. Participants were divided into four groups—Group 1: treated, high CVD risk; Group 2: treated, primary prevention; Group 3: untreated, high CVD risk; Group 4: untreated, low CVD risk. For each of these groups we compared cholesterol, HDL cholesterol, triglyceride and LDL cholesterol with targets recommended by the National Heart Foundation's 2005 guidelines.

Results: All lipids were at target in 39.4% of the study population with marked differences between groups: Group 1, 11.2%; Group 2, 38.5%; Group 3, 1.8%; Group 4, 47.6%.

Only 50.8% of the untreated high CVD risk group reported having blood cholesterol measured within the last 12 months.

Conclusion: Current rates of detection and treatment practices in rural Australia are suboptimal. Although one-third of the study population age 25–74 years are at sufficiently high risk to warrant consideration of lipid lowering medication only just over half of these were on treatment at the time of the study. These results suggest that an intensive implementation plan is required for the management of hyperlipidaemia in rural Australia.

Broad-scale mapping of temporary wetlands in arid Australia

We describe a robust methodology to detect and estimate the size of temporary wetlands using AVHRR satellite data within large areas (106 km2) of the arid zone. The methodology uses spectral matching and exclusion of salt surfaces to discriminate between water and non-water surfaces. The status of 115 lakes was used to evaluate the methodology. A classification accuracy of 98% was achieved for wetlands >120 ha, with accuracy of area estimates varying with the size and shape of individual lakes. Spectral matching of AVHRR data has methodological and cost advantages over the use of higher spatial resolution data for understanding changes in the distribution of water at broad scales.

Round the bend : a brief history of mental health nursing in Victoria, Australia 1848 to 1950's

This paper presents a history of mental health nursing in Victoria, Australia from 1848 to the 1950's, or the asylum years to the era of the mental hospital. The research for this historical overview was conducted as part of a literature review for a mental health nursing doctoral thesis, which included an account of the evolution of the profession from asylum attendant to the present time. The literature reviewed for this project revealed a distinct lack of a coherent, chronological account of the historical development of mental health nursing in Victoria, and this paper seeks to address that knowledge gap.
