Investigates the extraction kinetics of this Cr(VI) into a range of media. Develops an analytical method for the determination of Cr(VI) in acidic extract solutions and investigates the extraction of Cr(VI) under simulated in vivo conditions.

The impact of racism upon the health and wellbeing of young Australians

The Institute for Citizenship and Globalisation at Deakin University has worked in partnership with the Foundation for Young Australians to conduct this research project into the impact of racism upon the health and wellbeing of young Australians. The research has been carried out in eighteen Australian secondary schools in Victoria, New South Wales, Northern Territory and Queensland. Students aged 15-18 were surveyed and interviewed in both the government and Catholic education systems in order to ascertain the experience of racism and racist behaviours among Australian youth and their impact on health and wellbeing. The scope of the research brief included the nature of the racist experience, its setting, the individual and institutional responses and its reporting. The research also aimed to examine the impact of the experience of racism upon the health and wellbeing of Australian youth. A glossary of terms is included in Appendix 1 to assist with the reading of this Report.

The health and well-being of Sudanese young men in Melbourne

The health and well-being needs of young refugee men from Sudan are not adequately addressed by settlement services. To address this, I recommend using Ubuntu and Afrocentric approaches that emphasise dialogue. I have highlighted the problem areas where attention and action is needed for them to realise their full potential.

Employment status and mental health among persons with and without a disability: Evidence from an Australian cohort study

Background: Unemployment and economic inactivity are associated with worse mental health in the general population, but there is limited understanding of whether these relationships are different for those persons with mental or physical disabilities. The aim of this study was to assess whether there were differences in mental health by labour force status among persons with and without disabilities. Method: Over eight annual waves of the Household, Income and Labour Dynamics in Australia (HILDA) survey, a total of 2379 people with disabilities and 11 417 people without disabilities were identified. Mental health using the Mental Component Summary (MCS) from the Short Form 36 was modelled as a function of labour force status using fixed-effects regression models to control for time invariant confounding. Differences between those with and without disabilities were assessed by including an interaction term in regression models. Results: After finding evidence of effect modification, regression models were stratified by disability status. After adjustment, unemployment and economic inactivity were associated with a -1.85 (95% CI -2.96 to -0.73, p<0.001) and -2.66 (95% CI -3.46 to -1.86, p<0.001) reduction in scores of the MCS among those with a disability. For those without a disability, there were smaller declines associated with unemployment (-0.57, 95% CI -1.02 to -0.12, p=0.013) and economic inactivity (-0.34, 95% CI -0.64 to 0.05, p=0.022). Conclusions: These results suggest a greater reduction in mental health for those persons with disabilities who were unemployed or economically inactive than those who were employed. This highlights the value of employment for people with disabilities.

Providing health services to migrants and refugees settling in Victoria, Australia: an analysis of the complexity, cost and policy implications for public health

The aim of the research was to identify factors related to the increased costs of providing health services to clients from a non-English speaking background (NESB), using a cross-sectional analysis of the administrative records of clients using community health services in the Northern Metropolitan region of Melbourne for the 2001/2002 financial year. The higher cost of providing services to NESB clients was influenced by four factors: increased consultation time, group attendance to an appointment, increased interpreting costs and the type of service provider. Family members and multilingual staff play a significant role in providing informal interpreting services or low-cost support for NESB consultants, and these activities should receive appropriate support. Additional funding is needed to support interpreting requirements when dealing with the health needs of NESB clients.

The Resilient Families program: promoting health and wellbeing in adolescents and their parents during the transition to secondary school.

Resilient Families is a school-based prevention program designed to help students and parents develop knowledge, skills and support networks to promote health and wellbeing during the early years of secondary school. the program is designed to build within-family connectedness (parent--adolescent communication, conflict resolution) as well as improve social support between different families, and between families and schools. It is expected to promote social, emotional and academic competence and to prevent health and social problems in youth.

Health promotion and health education in schools : trends, effectiveness and possibilities

This report involved an extensive literature review as well as discussions with ten leading school health and traffic safety education researchers and practitioners. The findings of the report show that despite health promotion and health education activities occurring in all Victorian schools, school health related initiatives could be improved by focusing on cognitive outcomes and involving appropriate components of Health Promoting School (HPS) framework. Providing teachers with professional development and utilising interactive resources that complement the curriculum is also important. The report recommendations outline ways to improve the Health Promotion and Health Education and provide a potential framework for delivering TSE provision in schools.

Traffic safety education and health promoting school : a metropolitan and rural pilot study

Traffic Safety Education (TSE) is an important part of a school's program; however, it competes with many other components of schooling such as literacy, numeracy and a number of health areas. Hence TSE provision in Victorian schools has been somewhat fragmented and haphazard in its delivery. This small pilot study involved two metropolitan and two rural schools which attempted to link TSE into mainstream school activities through the new Victorian Essential Learning Standards (VELS) utilising the internationally accepted Health Promoting Schools (HPS) framework.
The findings of the pilot study showed that though schools face many demands, understanding and ownership of TSE is possible when administrative support, professional development and adequate planning time are made available. The report outlines several key recommendations to improve the delivery of Traffic Safety Education in Victorian schools.

Exposure estimation, uncertainty and variability in occupational hygiene retrospective assessment

This thesis reports on a quantitative exposure assessment and on an analysis of the attributes of the data used in the estimations, in particular distinguishing between its uncertainty and variability. A retrospective assessment of exposure to benzene was carried out for a case control study of leukaemia in the Australian petroleum industry. The study used the mean of personal task-based measurements (Base Estimates) in a deterministic algorithm and applied factors to model back to places, times etc for which no exposure measurements were available. Mean daily exposures were estimated, on an individual subject basis, by summing the task-based exposures. These mean exposures were multiplied by the years spent on each job to provide exposure estimates in ppm-years. These were summed to provide a Cumulative Estimate for each subject. Validation was completed for the model and key inputs. Exposures were low, most jobs were below TWA of 5 ppm benzene. Exposures in terminals were generally higher than at refineries. Cumulative Estimates ranged from 0.005 to 50.9 ppm-years, with 84 percent less than 10 ppm-years. Exposure probability distributions were developed for tanker drivers using Monte Carlo simulation of the exposure estimation algorithm. The outcome was a lognormal distribution of exposure for each driver. These provide the basis for alternative risk assessment metrics e.g. the frequency of short but intense exposures which provided only a minimal contribution to the long-term average exposure but may increase risk of leukaemia. The effect of different inputs to the model were examined and their significance assessed using Monte Carlo simulation. The Base Estimates were the most important determinant of exposure in the model. The sources of variability in the measured data were examined, including the effect of having censored data and the between and within-worker variability. The sources of uncertainty in the exposure estimates were analysed and consequential improvements in exposure assessment identified. Monte Carlo sampling was also used to examine the uncertainties and variability associated with the tanker drivers' exposure assessment, to derive an estimate of the range and to put confidence intervals on the daily mean exposures. The identified uncertainty was less than the variability associated with the estimates. The traditional approach to exposure estimation typically derives only point estimates of mean exposure. The approach developed here allows a range of exposure estimates to be made and provides a more flexible and improved basis for risk assessment.

Dancing with death : risk, health promotion and injecting drug users

The thesis investigated ambivalent attitudes towards death in injecting drug users, factors that may lead to such ambivalent attitudes and implications for health promotion campaigns. It was found that this relationship with death was principally attributable to government drug policy in Australia.
