Introduction : It is commonly acknowledged that, for many offenders, alcohol use is strongly associated with criminal behaviour. The belief held by many professionals that the two phenomena are associated, probably in a causal way, has led to the inclusion of alcohol use as a ‘criminogenic need’ in many settings where rehabilitation programmes are used to reduce recidivism. However, the mechanisms and pathways involved in the alcohol–crime link remain poorly understood.
Argument and conclusion : This paper reviews the literature relating to alcohol–offending links and draws some inferences about the role of alcohol use as a criminogenic need in offender rehabilitation. It is proposed that the bi-directional relationship between alcohol use and negative affective states is important in understanding the offence cycle, and that deficits in self-regulation not only characterize both alcohol misuse and negative affect but are also implicated in the offending behaviour itself.

This paper examines data from a research project that investigated the cultural drivers of drinking in 14-24 year-old Australians, funded by Drinkwise Australia and the Department of Health and Ageing. At the same time that we were working on this project a moral panic about young people, risk and binge drinking had once more energised public debate. Prominent here was the highly politicised imputation of a strategic taxation levy on ready to drink products (alcopopos). This qualitative, interview-based project examined two separate but related aspects of young people's alcohol use: the roles played by sporting clubs, as community hubs, in shaping young people's use of alcohol: and young people's drinking biographies over different phases of their lives. This paper will focus on the sporting club study to discuss issues related to the positioning and serving of alcohol in the relation to young people. As part of the study, we conducted interviews with club administrators and young people in a range of sporting clubs. Insights from the study give rise to the potential for clubs to play an active and influential role in helping young people create positive/responsible approaches to alcohol consumption.

This paper explores the way that the state of Victoria in the late 20th century, in common with other advanced liberal regimes, produced the space for a free market in alcohol to use Nikolas Rose's term. This was in a country which had traditionally regulated alcohol production, distribution and retail sales for the health and welfare of the society as a whole.
From the mid 1960s a series of Royal Commissions and inquiries recommended the progressive dismantling of regulations related to the availability of alcohol in the state. This culminated in the 1985 Nieuwenhuysen Inquiry into alcohol regulation which was given the specific mandate to produce the conditions for what has been termed the Night Time Economy. This paper will trace some of the historical, cultural and economic changes which have happened and how these changes can be understood as an example of providing the space for a market in alcohol.

Recognizing there have been few methodologically rigorous cross-national studies of youth alcohol and drug behaviour, state student samples were compared in Australia and the USA. Sampling methods were matched to recruit two independent, state-representative, cross-sectional samples of students in Grades 5, 7 and 9 in Washington State, USA, (n = 2866) and Victoria, Australia (n = 2864) in 2002. Of Washington students in Grade 5 (age 11), 10.3% (95% CI 7.2–14.7) of boys and 5.2% (95% CI 3.4–7.9) of girls reported alcohol use in the past year. Prevalence rates were markedly higher in Victoria (34.2%, 95% CI 28.8–40.1 boys; 21.0%, 95% CI 17.1–25.5 girls). Relative to Washington, the students in Victoria demonstrated a two to three times increased likelihood of reporting substance use (either alcohol, tobacco or illicit drug use), and by Grade 9, experiences of loss-of-control of alcohol use, binge drinking (frequent episodes of five or more alcoholic drinks), and injuries related to alcohol were two to four times higher. The high rates of early age alcohol use in Victoria were associated with frequent, heavy and harmful alcohol use and higher overall exposure to alcohol or other drug use. These findings reveal considerable variation in international rates of both adolescent alcohol misuse and co-occurring drug use and suggest the need for cross-national research to identify policies and practices that contribute to the lower rate of adolescent alcohol and drug use observed in the USA in this study.

Drawing on interviews about the drinking trajectories of sixty young Victorian drinkers (aged 20-24), this paper outlines patterns of change over time and explores two drinking biographies in depth. For most research participants, drinking alcohol was an enjoyable and integral part of their social lives, but its role changed as they made other transitions in their lives. Most participants considered their early twenties to be a time for heavy alcohol consumption, and most imagined that they would drink less when they were middle-aged.

This thesis is concerned with the effect of alcohol consumption on the pathogenesis of bleeding from the upper gastrointestinal tract via nutritional pathways. Altered nutritional status is a frequently recognised clinical accompaniement of heavy alcohol consumption in hospitalized patients. Similarly, upper gastrointestinal bleeding is frequently accompanied by the presence of heavy alcohol consumption. Nevertheless, the clinical quantification of alcohol intake is often descriptive, so that a link between alcohol use and upper gastrointestinal haemorrhage via nutritional mechanisms has been only generally defined. In the literature review, the methods of defining alcohol use and abuse, using interview, biochemical and haematological techniques are noted. The relationship between alcohol abuse and nutrient imbalances is reviewed, especially in relation to possible effects on the gastrointestinal tract, appetite and eating habits. A further section reviews the relationship between alcohol use and anatomical lesions of the upper gastrointestinal tract likely to lead to bleeding. Following the chapter in which the methods used in this thesis are described. Chapter 4 seeks to describe the study population and its subgroups in this thesis in relation to interview, biochemical and haematological methods. Alcohol use is defined in relation to (1) a clinical classification of heavy or light drinking, based on a questionnaire administered in Casualty, (2) a quantified method of determining alcohol consumption during a subsequent ward dietetic assessment, (3) in relation to a biochemical definition (recent drinking and non-drinking), and a classification of (1) and (2) called, for the purposes of this thesis, 'alcohol abusers' and 'nonabusers'. Heavy, regular and recent drinkers and alcohol abusers tend to be male and younger than light, infrequent and nonrecent drinkers and nonabusers. Chapter 5 relates the nutritional status of those patients admitted acutely to hospital in relation to the groups defined in Chapter 4, Nutritional status is defined in terms of food intake, anthropometry, biochemical and haematological parameters. Different methods of defining alcohol use give rise to different patterns of nutritional impairment. Chapter 6 relates the nutritional status of those patients admitted acutely to hospital in relation to the presence or absence of an endoscopically defined site of upper gastrointestinal bleeding. A difference is seen between those bleeding from a Mailory-weiss tear and other sites of bleeding, similarly, biochemical differences in nutritional status emerge between those patients who presented in shock, and those who did not. Chapter 7 explores the relationships between biochemical markers of nutritional status and haemostatic variables in the groups of abusers/non-abusers, the various sites of primary bleeding/controls, and shock/non-shock. Serum copper appears to be related to altered haemostasis in a manner not apparently described elsewhere.

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.
Dynamic mechanical analysis of poly (vinyl alcohol)/Silica Nanocomposite Prepared with SAM Technique

The thermooxidative degradation of poly (vinyl alcohol)/silica (PVA/SiO2) nanocomposite prepared with self-assembly monolayer (SAM) technique is investigated by using a thermogravimetry (TG) and Fourier transform infrared spectroscopy coupled thermogravimetry (FTIR/TG). The results show that although the thermooxidative degradation process of prepared nanocomposite is similar to that of the pure PVA, its thermooxidative stability has been greatly improved.
