Juvenile justiceAdministration ofNew South Wales.Juvenile delinquentsRehabilitationThis study examines the process of Youth Justice Conferencing in New South Wales within the context of the theory and aims of the restorative justice movement. Analysis of relevant literature and theory suggests that restorative justice is a broad and encompassing movement that entails a decision making process where victims, communities and offenders come together in a joint response to an offence. Although this breadth has allowed and encouraged a proliferation of programs that respond to particular needs and particular demands of culture and social context, the consequence is that both understandings and practices of restorative justices are variable. When theoretical understandings are so varied there will necessarily be a lack of commonality in the way principles are articulated. If practice is not linked directly to principled theory it is inevitable that processes will be vulnerable at all levels to the interaction between context, situations and participant characteristics that may easily deflect the focus from the true purpose of restorative justice. This thesis attempts to clarify the restorative principles relevant to the NSW program with reference to Braithwaite and Pettit???s republican theory (1990) and their notion of dominion. In turn these principles are used to identify five practical elements to be used as a framework to guide youth conferences. Such a framework highlights potential areas for improvement in conference preparation and practice. A case study approach was used to collect data and involved the observation of eighty five Youth Justice Conferences in three New South Wales conferencing regions. As well, one hundred and fifty two currently practising Youth Justice Conferencing practitioners (Police, Conveners, Managers) in New South Wales completed a mail out questionnaire. Findings from the study suggest that conference processes are influenced by the presence or absence of five particular elements: the attendance of victims, the attendance of communities, the attendance of offender support, reparation to victims, communities and offenders and the experience of non-domination during the conference space. However, findings also suggest that ???situational??? factors may mediate these key elements to enhance or compromise the overall process. This thesis suggests that many of the issues arising in NSW conferences result from the failure to articulate the links between restorative justice theory and practice. While in NSW such links may intentionally have been unarticulated in order to encourage a freedom within the process, in reality the lack of clarification has led to a freedom in discretion that sometimes diminishes the chance of success. Therefore it proposes the need for a more articulated translation of theory into principles that will in turn frame practice. In this way the thesis uses the normative theory proposed by Braithwaite and Pettit (1990) to provide an explanatory and ideal framework for best practice in NSW Youth Justice Conferencing.

The development of major commercial airports promotes the air transport industry and generates positive economic benefits to the airport and to its host economy. However, external costs are associated with these benefits. Any increase in aircraft movement causes negative environmental impacts, especially noise pollution. Governments have reduced aircraft noise levels at their sources, or introduced aircraft noise management strategies (ANMS); however the problems have never been satisfactorily resolved. This research aims at developing a better understanding of the impacts of aircraft noise on community health and well-being by exploring two core research questions: (1) ???Is health related quality of life worse in communities chronically exposed to aircraft noise than in communities not exposed????; and (2) ???Does long-term aircraft noise exposure associate with adult high blood pressure level via noise stress as a mediating factor????. The Sydney (Kingsford Smith) Airport has been selected as a case study. The health survey instruments have been developed and piloted, and then translated from English into Greek and Arabic. A postal self-administrative health survey (with follow-up letters) has been implemented in the areas surrounding Sydney Airport (called ???aircraft noise exposure group???) and in the matched control group. The total sample size was 1,500 with 47% response rate. This thesis has developed a ???new??? noise index (named Noise Gap Index, NGI) to describe and assess aircraft noise in such a way that is easily understood by the layperson. Factorial analysis of covariance revealed that ???Health related quality of life, in term of physical functioning, general health, vitality, and mental health, of community chronically exposed to high aircraft noise level were worse than the matched control area???. Binary logistic regression analysis found that ???Subjects (aged 15 ??? 87) who have been chronically exposed to high aircraft noise level have the odds of 2.61 of having chronic noise stress. In addition person who have chronic noise stress have the odds of 2.74 of having hypertension compared with those without chronic noise stress???. Finally, the robust hypotheses of effects of aircraft noise on community health and well-being for future experimental study were proposed.

Healthcare reforms and restructuring have been a global phenomenon since the early 1980s. The major structural reforms in the healthcare system in New South Wales (NSW) including the introduction and implementation of the area health management model (1986), the senior executive service (1989) and performance agreements (1990), heralded a new era in management responsibility and accountability. It is believed that the reforms, the process of the reforms, and the instability brought about by the reforms may have not only resulted in the change of senior healthcare management practices, but also in the change of competencies required for senior healthcare managers in meeting the challenges in the new era. However, limited studies have been conducted which examined how health reforms affected its senior health executive workforce and the above changes. Moreover, no study on senior healthcare managers has focused specifically on NSW after the major reforms were implemented. The purpose of this research was to examine how reforms in the NSW Health public sector affected its senior health executive workforce between 1990 and 1999 in terms of their roles and responsibilities, the competencies required, and the challenges they faced. This study, from a broad perspective, aimed to provide an overview of the NSW reforms, the forces behind the reforms and the effects the reforms may have had on senior health managers as predicted by the national and international literature. This study also explored the changes to the senior health executive workforce in the public sector during the period of rapid change in the 1990s and has provided indications of the managerial educational needs for future senior healthcare managers. Both quantitative and qualitative data have been collected by this study using triangulated methods including scientific document review and analyses, a postal questionnaire survey, and in-depth telephone interviews. The findings from the two quantitative methods informed and guided the development of the open-ended questions and overall focus of the telephone interviews. This study found differences in the characteristics and employment-related aspects between this study and previous studies in the 1980s and 1990s, and identified four major tasks, twelve key roles and seven core competencies required by senior health executives in the NSW Health public sector between 1990 and 1999. The study concludes that the demographic characteristics and the roles and responsibilities of the NSW Health senior executive workforce since the reforms of the 1980s have changed. This study also identified seven major obstacles and difficulties experienced by senior health executives and suggested that during the introduction and implementation of major healthcare reforms in NSW since 1986, barriers created by the ‘system’ prevented the achievement of its full potential benefits. Although this study did not focus on detailed strategies on how to minimise the negative impact of the health reforms on the senior health executives or maximise the chance of success in introducing new changes to the system, some suggestions are proposed. Most significantly, the study has developed a clear analytical framework for understanding the pyramidal relationships between tasks, roles and competencies and has developed and piloted a new competency assessment approach for assessing the core competencies required by senior health managers. These significant findings indicate the need for a replication of the study on an Australia-wide scale in order to extend the generalisability of the results and test the reliability and validity of the new competency assessment approach at various management levels in a range of healthcare sectors. This is the first study acknowledging the impact of the introduction of the area health management model, the senior executive service and performance agreements in the NSW public health system through an original insight into the personal experiences of the senior health executives of the reforms and examination of the major tasks that senior health executives performed and relevant essential competencies required to perform these tasks. The possible solutions identified in this study can guide the development of strategies in providing better support to senior healthcare managers when large-scale organisational changes are proposed in the future.

This thesis takes the Sydney 2002 Gay Games: Under New Skies �02, as a case study into the production of global queer citizenship. In the existing body of work around the Gay Games they are analysed as an international gay and lesbian sporting event (Cramer, 1996; Krane et al., 2001; Pronger, 2000; Waitt, 2005), as a gay and lesbian community event (Krane & Waldron, 2000; Symons, 2002, 2004; Waitt, 2003, 2006), and as a cultural site where discourses of nationality, sport and sexuality converge (Miller, 2001; Probyn, 2000; Rowe et al., 2006; Stevenson et al., 2005; Waitt, 2005; Waitt & Markwell, 2006). This thesis builds on these investigations, asking specific questions about the ways in which discourses of sexuality and citizenship are produced and governed within and across the Sydney 2002 Gay Games promotional and media materials. The analysis is guided by Michel Foucault�s notion of governmentality (1991) and the works of related theorists who map the disparate array of neoliberal mechanisms of government that �conduct the conduct� and �act on the actions� of individuals and certain populations (Bratich et al., 2003; Gordon, 1991; Larner, 2000; Larner & Walters, 2002, 2004; Miller, 1993; Rabinow & Rose, 2003; Rose, 1996a, 1999). The analysis begins by asking how discourses of the autonomous, neo-liberal subject converge with discourses of �global living� such that individuals are invited to imagine themselves as increasingly flexible, freedom-loving (Rose, 1999), self-assured, cosmopolitan global citizens. The idea of the global imagination is then used to explore the ways in which the Gay Games commitment to �total inclusion� and its promise of personal and community transformation rely on similar neo-liberal renderings of tbe subject. It argues that the event�s �political� promises not only normalise certain forms of identity-based consumption (Chasin, 2000), they also (re)produce and normalise a very entrepreneurial, western-centric, cosmopolitan �brand� of global queer citizenship. The thesis also emphasises the important role that images and image-related technologies played in upholding normative meanings around queer sexuality and queer citizenship at the Games. In doing so, the thesis argues that images and technologies do more than simply represent individuals� lived experiences. Images, it argues, are (inter)active entities that produce and shape individuals� understanding of the �real� and how they come to know themselves as certain types of subjects. Where the Sydney 2002 Gay Games were concerned, images were integral in producing normative meanings around gender, sexuality and citizenship and in governing participants� experiences as �locals�, �global visitors�, �athletes�, �cultural participants� and consumers.

When the Human Rights and Equal Opportunities Commission tabled Bringing them home, its report into the separation of indigenous children from their families, it was criticised for failing to consider Indigenous child welfare within the context of contemporary standards. Non-Indigenous people who had experienced out-of-home care also questioned why their stories were not recognised. This thesis addresses those concerns, examining the origins and history of the welfare systems of NSW and Tasmania between 1880 and 1940. Tasmania, which had no specific policies on race or Indigenous children, provides fruitful ground for comparison with NSW, which had separate welfare systems for children defined as Indigenous and non-Indigenous. This thesis draws on the records of these systems to examine the gaps between ideology and policy and practice. The development of welfare systems was uneven, but there are clear trends. In the years 1880 to 1940 non-Indigenous welfare systems placed their faith in boarding-out (fostering) as the most humane method of caring for neglected and destitute children, although institutions and juvenile apprenticeship were never supplanted by fostering. Concepts of child welfare shifted from charity to welfare; that is, from simple removal to social interventions that would assist children's reform. These included education, and techniques to enlist the support of the child's family in its reform. The numbers of non-Indigenous children taken into care were reduced by economic and environmental measures, such as payments to single mothers. The NSW Aborigines Protection Board dismissed boarding-out as an option for Indigenous children and applied older methods, of institutionalisation and apprenticeship, to children it removed from reserves. As non-Indigenous welfare systems in both states were refined, the Protection Board clung to its original methods. It focussed on older children, whilst allowing reserves to deteriorate, and reducing the rights of Aboriginal people. This cannot simply be explained by race, for Tasmania did not adopt the same response. This study shows that the policies of the Aborigines Protection Board were not consonant with wider standards in child welfare of the time. However, the common thread between Indigenous and non-Indigenous child removal was the longing of children and their families for each other.

In rural inland, south-eastern Australia, allergy to the fungus Alternaria is prevalent and an important risk factor for asthma. The aim of the thesis was to investigate the distribution and factors influencing allergens of Alternaria in the air. As airborne allergenic spores were thought to arise from harvesting of nearby crops, two towns with different agricultural practices were studied. Moree has two crop harvesting periods in summer and autumn whilst Wagga Wagga has one harvesting period in summer. Over two years, air was sampled daily in Wagga Wagga and Moree using Burkard traps. The reliability of measurements from a single site to represent the distribution of airborne concentrations of spores across each town was examined using data from three traps simultaneously, sited 2.0 to 4.9 km apart, over four weeks. Substantial intra-class correlation coefficients (ICC) were observed between the three sampling sites across both towns (ICC=0.52, 95% CI 0.30-0.71 to 0.76, 95% CI 0.61-0.87) when counts of Alternaria spores were relatively high. The correlation was poor when counts were low. Of more than 365 trap tapes examined, the two microscopic traverses strongly correlated for counts of Alternaria spores (ICC=0.95, 95% CI 0.94-0.96). Alternaria was detected in both towns throughout the two year period with peaks in spore concentrations reflecting the season of crop harvesting in each region. Individual exposure to spores was examined. Thirty three subjects (adults and children from nine families) wore nasal air samplers and personal air samplers both inside and outside their homes. The effects of activity, location, age on the inhalation of Alternaria spores and variation between individuals in the same environment were determined. Every subject inhaled Alternaria spores. Personal exposure to Alternaria in the home environment varied substantially between subjects. Levels of fungal spores inhaled were higher during periods of activity than during rest, and higher while subjects were outdoors than indoors. During outdoor activity, the number of Alternaria spores inhaled ranged from 4 to 794 (median 11) spores/hr. Sources of airborne spores was investigated by sampling air above wheat and cotton crops near the towns during harvesting and non-harvesting periods, in a grain and cotton seed storage shed, and a cotton gin. Substantially higher concentrations were detected above crops during harvesting periods compared to non-harvesting periods. Peaks were associated with harvesting and other activities where plants were manipulated. By regression analysis spore concentrations in both towns were modelled against those detected above crops and with weather variables. Only one crop sampling period (cotton harvest) independently correlated with concentrations in town. Analysis combining all data showed concentrations of spores above crops correlated with spore concentrations in the town when lagged by one day. Variables of rainfall and maximum temperature influenced concentrations in both towns, and wind direction in Wagga Wagga alone. Parents of asthmatic children were asked by questionnaire in which locations symptoms were provoked. Asthma was reported to be exacerbated at grain farms and with disturbance of local vegetation in town and home gardens. Nasal sampling confirmed that activities that disturbed dust or vegetation increased the inhalation of spores. The factors that release allergen from spores were determined in a modified Halogen immunoassay. Approximately 60% of spores released allergen, and the proportion was influenced by isolate, nutrient availability, viability, and not influenced by sunlight or culture age up to 21 days. Germinating the spores significantly increased the proportion that released total allergen and Alt a 1 (p<0.0001). Alt a 1 appears to be a minor contributor to the total allergen released from spores except when spores have germinated. Conclusions: People living in inland rural regions of Australia are exposed to substantial quantities of allergenic spores of Alternaria. Exposure is a highly personal event and is largely determined by disturbance of local vegetation releasing spores such as from nearby crops by wind, harvesting, slashing, transport and processing of produce, and from within town and home gardens. Most spores inhaled are likely to be allergenic, with potency potentially increasing with viability.

Master of Arts (Research) / This thesis examines a ledger which listed all the causes of death in Darlinghurst Gaol, Sydney’s main gaol, from 1867 to 1914 when the gaol was closed and all the prisoners were transferred to the new Long Bay Gaol at Maroubra. The ledger lists the name of the deceased prisoner, the date of their death, the age of the prisoner at the time of their death and the cause of death along with any special comments relevant to the death where necessary. This ledger was analysed in depth and the death rates and diseases causing the deaths were compared to the general population in New South Wales and Australia as well as to another similar institution namely Auburn Prison, the oldest existing prison in New York State and the general population of the United States of America (where possible). Auburn Prison was chosen because it was the only other prison in the English speaking world (British Empire and United States of America) that had a similar complete list of deaths of prisoners in the same time frame – in this case beginning in 1888. The comparison showed that the highest death rates were in the general population of the United States of America (statistics on New York State alone could not be found) followed by Auburn Prison followed by the general population of Australia then the general population of New South Wales (the latter two were very similar) and the lowest death rates were in Darlinghurst Gaol. The analysis showed that individuals were less likely to die in the main prison, compared to the relevant general population in New South Wales and New York State despite the fact that 8 – 9% of these prison deaths were due to executions, a cause of death not encountered in the general population. This thesis explores the reasons why mortality rates were lower in prison despite the popular perception was that Victorian era gaols were places of harshness, cruelty and death (think of the writings of Charles Dickens, the great moralist writer who was the conscience of the era) compared to the general free population.

The purpose of this study was twofold. First, it aimed to present an argument for the inclusion of primary-age children's views in the decision-making process in primary schools. Second, it aimed to explore the potential of primary-age children to contribute to better decisions about their own schooling. The hypothesis is that primary-age children have worthwhile views of schooling that should be introduced into both classroom and school decision-making processes. Authoritarianism, moral development, childrenqs rights and active learning were explored in relation to child participation in decision-making. This study attempted to explore children's views of schooling from the viewpoints of the children themselves. Children kept diaries of school for one week and from these diaries an interview schedule was constructed to allow the exploration of their views. The study shows that primary-age children have views that can contribute legitimately and valuably to decision-making at both the classroom and school levels.

THESIS ORGANISATION This thesis is organised into nine chapters that include seven international and national publications (six accepted and one submitted for publication). The initial overview chapter outlines the justification and direction for this thesis. With the exception of chapter 8 (accepted for publication on the 1st May 2005); all chapters are exact duplicates of published articles in international and national refereed journals (chapters 2 to 7). The initial chapters (2 and 3) presents research findings using a marine fish species, mullet (Mugil cephalus), to measure trace metal bioavailability in Lake Macquarie, NSW Australia. While subsequent chapters (4 to 8) are presenting research under taken to improve the understanding of arsenic cycling in marine and estuarine environments. The final chapter (chapter 9) is a synopsis of the major findings presented in this thesis. Due to the publication nature of this thesis, an unavoidable degree of replication exists within chapters (publications).

The following research project was a comparative study of teachers in Support Units and teachers in Special Schools. They were teachers currently involved with the implementation of the 1989 NSW Department of Education Mandatory Curriculum Change for the education of students with severe intellectual disability. The purpose of the research was to present a comparative study on teachers' responses, in both educational settings, examining their understanding of the curriculum change, the concerns of individuals and the levels of curriculum usage in relation to the factors affecting implementation. The application of the Concerns-Based Adoption Model of Change (Hall and Loucks, 1987), enabled the study to focus on the various forms of the innovation, including the innovation configuration, stages of concern, and the levels of use from the two given perspectives, teachers in Support Units and teachers in Special Schools, in relation to the major factors affecting implementation. The study findings highlighted that in both educational settings, change is accomplished by individuals and is a highly personal experience, demanding adequate support by facilitators of the change through appropriate actions, in order to assist effective and successful implementation of the change.
