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.

Is restricting tobacco sales the answer to adolescent smoking?

Background: Enforcement of legislation restricting retail access to tobacco is increasingly relied on to reduce adolescent smoking rates. In 1996, health authorities in the Northern Sydney Health Area began monitoring tobacco retailer compliance (PROOF program) with staged purchase attempts by adolescents below the legal age (18 years).

Methods: Repeat cross-sectional surveys before (1995) and after (2000) the introduction of PROOF monitored changes in adolescent smoking behaviour. Students aged 12 to 17 years from 11 Northern Sydney metropolitan public secondary schools were surveyed for self-reported smoking and tobacco purchasing behavior in 1995 (n = 5,206) and 2000 (n = 4,120).

Results: Between 1996 and 2000, 545 retailer compliance checks found 34% unlawfully sold cigarettes to minors and 28% of these repeated the offence. Nine prosecutions resulted. Modelling revealed a significant association between the intervention and never having smoked (adjusted OR = 1.16, 95% CI = 1.01–1.33) although there was no significant association with being a current smoker. The odds of being a smoker were greater for students from coeducational schools, with this effect being modified by gender.

Conclusions: There was no reduction in adolescent smoking with active enforcement of tobacco access laws despite an apparent increase in students who reported never to have smoked.

Review of prevalence data in, and evaluation of methods for cross cultural adaptation of, UK surveys on tobacco and alcohol in ethnic minority groups

Objective To assess the adequacy of cross cultural adaptations of survey questions on self reported tobacco and alcohol consumption in the United Kingdom.

Design Assessment of consistency of data between studies identified through literature review. Studies evaluated with 12 guidelines developed from the research literature on achieving cross cultural comparability.

Results The literature review identified 18 key studies, five of them on national samples. Survey instruments were obtained for 15 of these. The comparison of prevalence data in national surveys showed some important discrepancies, greater for tobacco than for alcohol. For example, prevalence of cigarette smoking in Bangladeshi women was 6% in a national survey in 1994 and 1% in a national survey in 1999; in Chinese men it was 31% in a survey in 1993-4 and 17% in one in 1999; in African-Caribbean men it was 29% in a 1992 survey and 42% in one in 1993-4. The most guidelines met by any study was three, although one study partly met a fourth. Two studies met no guidelines. Only four studies consulted with ethnic minority communities in developing the questionnaire, none checked each language version with all others, and two stated the questionnaire had not been validated.

Conclusions Surveys have not followed best practice in relation to measurement of risk factors in cross cultural settings. There is inconsistency in the prevalence data on smoking provided by different major national UK studies. Users of such data should be aware of their limitations. Research is needed to help achieve linguistic equivalence of survey questions in cross cultural research.

Cross-cultural adaptation of a tobacco questionnaire for Punjabi, Cantonese, Urdu and Sylheti speakers: qualitative research for better clinical practice, cessation services and research.Â

Objective : To develop cross‐culturally valid and comparable questionnaires for use in clinical practice, tobacco cessation services and multiethnic surveys on tobacco use.
Methods : Key questions in Urdu, Cantonese, Punjabi and Sylheti on tobacco use were compiled from the best existing surveys. Additional items were translated by bilingual coworkers. In one‐to‐one and group consultations, lay members of the Pakistani, Chinese, Indian Sikh and Bangladeshi communities assessed the appropriateness of questions. Questionnaires were developed and field tested. Cross‐cultural comparability was judged in a discussion between the researchers and coworkers, and questionnaires were finalised. Questionnaires in Cantonese (written and verbal forms differ) and Sylheti (no script in contemporary use) were written as spoken to avoid spot translations by interviewers.
Results : The Chinese did not use bidis, hookahs or smokeless tobacco, so these topics were excluded for them. It was unacceptable for Punjabi Sikhs to use tobacco. For the Urdu speakers and Sylheti speakers there was no outright taboo, particularly for men, but it was not encouraged. Use of paan was common among women and men. Many changes to existing questions were necessary to enhance cultural and linguistic appropriateness—for example, using less formal language, or rephrasing to clarify meaning. Questions were modified to ensure comparability across languages, including English.
Conclusion : Using theoretically recommended approaches, a tobacco‐related questionnaire with face and content validity was constructed for Urdu, Punjabi, Cantonese and Sylheti speakers, paving the way for practitioners to collect more valid data to underpin services, for sounder research and ultimately better tobacco control. The methods and lessons are applicable internationally.

Sewage disposal and ocean pollution : contradictory world views as a theme in policy change

Explores the process of state policy making in the area of sewage disposal and pollution management. Argues that contradictory world views form the milieu of understanding through which environmental policy is shaped. The dynamic tension between two contradictory views is explained mainly through events within two regional water authorities in Victoria during the 1980s.. The analysis suggests that a process of incremental change in the shaping of environmental policy is taking place.

Utilization of bacteriophage NCIMB-10645 of Serratia marcescens strain NCIMB-10644 as a tracer of pollution from an ocean sewage outlet

Bacteriophage NCIMB-10645 of Serratia marcescens (NCIMB-10644) was assessed as a tracer of aquatic contamination with the intention of using it at the Black Rock ocean outfall in South Eastern Australia. Growth conditions and a liquid culture growth curve were assessed. The bacteriophage was subjected to survival trials and a method of concentrating NCIMB-10645 developed. NCIMB-10645 was assessed as a tracer at Deakin University then released from the Black Rock Sewage Treatment Plant. Contamination movement away from the treatment plant was found to be predominantly affected by Easterly wind conditions.

Only thin smoke without flame

Hardy's short stories have been relatively neglected by critics. This thesis argues for their reconsideration and proper recognition as essential components of Hardy's achievement. Examines his creation of a fictional "Wessex" with himself as conservator, but suggests that their subversive ideologies touching on modern themes, make him a "proto-modern" writer.

The impact of school tobacco policies on student smoking in Washington State, United States and Victoria, Australia

This paper measures tobacco polices in statewide representative samples of secondary and mixed schools in Victoria, Australia and Washington, US (N = 3,466 students from 285 schools) and tests their association with student smoking. Results from confounder-adjusted random effects (multi-level) regression models revealed that the odds of student perception of peer smoking on school grounds are decreased in schools that have strict enforcement of policy (odds ratio (OR) = 0.45; 95% CI: 0.25 to 0.82; p = 0.009). There was no clear evidence in this study that a comprehensive smoking ban, harsh penalties, remedial penalties, harm minimization policy or abstinence policy impact on any of the smoking outcomes.
