Macoun, Alissa. "Aboriginality and the Northern Territory intervention". Thesis, University of Queensland, 2012. https://eprints.qut.edu.au/65357/1/Macoun_phd_finalthesis.pdf.
Testo completoAbstract (sommario):
This thesis examines the construction of Aboriginality in recent public policy reasoning through identifying representations deployed by architects and supporters of the Commonwealth’s 2007 Northern Territory Emergency Response (the intervention).
Debate about the Northern Territory intervention was explicitly situated in relation to a range of ideas about appropriate Government policy towards Indigenous people, and particularly about the nature, role, status, value and future of Aboriginality and of Aboriginal people and Torres Strait Islanders. This project involves analysis of constructions of Aboriginality deployed in texts created and circulated to explain and justify the policy program. The aim of the project is to identify the ideas about Aboriginality deployed by the intervention’s architects and supporters, and to examine the effects and implications of these discourses for political relationships between Indigenous people and settlers in Australia.
This thesis will argue that advocates of the Northern Territory intervention construct Aboriginality in a range of important ways that reassert and reinforce the legitimacy of the settler colonial order and the project of Australian nationhood, and operate to limit Aboriginal claims.
Specifically, it is argued that in linking Aboriginality to the abuse of Aboriginal children, the intervention’s advocates and supporters establish a political debate about the nature and future of Aboriginality within a discursive terrain in which the authority and perspectives of Indigenous people are problematised. Aboriginality is constructed in this process as both temporally and spatially separated from settler society, and in need of coercive integration into mainstream economic and political arrangements.
Aboriginality is depicted by settler advocates of intervention as an anachronism, with Aboriginal people and cultures understood as primitive and/or savage precursors to settlers who are represented as modern and civilised. As such, the communities seen as the authentic home or location of Aboriginality represent a threat to Aboriginal children as well as to settlers. These constructions function to obscure the violence of the settler order, provide justification or moral rehabilitation for the colonising project, and reassert the sovereignty of the settler state. The resolution offered by the intervention’s advocates is a performance or enactment of settler sovereignty, representing a claim over and through both the territory of Aboriginal people and the discursive terrain of nationhood.

Testo completoAbstract (sommario):
This research documents, for the first time, the experiences of non-Aboriginal primary health workers caring for terminally ill Aboriginal patients in Central Australia. Despite the high mortality amongst Aboriginal Territorians, issues around terminal illness, death and bereavement have been little studied. The area is sensitive in both cultural and human terms. Many clients of the local health care services are Aboriginal people whereas most nurses and doctors are non-Aboriginal. Their clinical interactions are inherently cross cultural and are additionally influenced by several sequelae of Australian colonial history, including socioeconomic and status disparity between participants and entrenched discriminatory attitudes and practices. The study was approached from the perspective of the new public health, informed by the philosophy of contemporary palliative care and aimed to contribute to the development of a culturally safe practice for the care of terminally ill Aboriginal people. Data was collected using a qualitative method of serial interviews with a representative sample of primary health care workers with an Aboriginal clientele. The study found that cultural factors were important determinants of good health care communication, the making of appropriate end-of-life care decisions and the provision of quality case management and bereavement support. Significant cultural issues for achieving a “good death” included recognition of the wish of many Aboriginal people to die on their own country and of the value of the Aboriginal kinship system for enabling care decisions and providing care. To date however, these have had little formal impact on the design or delivery of health care services for terminally ill Aboriginal people in Central Australia. Nurses and doctors interviewed for this study considered Aboriginal patients’ access to quality health care during a terminal illness to be inadequate and inequitable. The difficulties of providing health care in remote areas impacted disproportionately on Aboriginal clients. Their treatment options were limited by their poverty and by institutional policies determining the availability of resources. Cultural and language mis-communication between Aboriginal clients and non-Aboriginal health professionals impaired the process of decision making and the delivery of care. The hegemony of the majority culture and its health care institutions disempowered Aboriginal clients while entrenched discriminatory social attitudes perpetuated inequitable practices. Specific service gaps were identified in the availability of interpreter services, transportation, respite care, domiciliary nursing and bereavement support. The wider care network, including hospitals, nursing homes, multidisciplinary health care providers, and the transport needed for remote clients to access these, was inequitably available and insufficiently accommodating of Aboriginal cultural needs. The existing palliative care services employed no Aboriginal staff. Improving care will therefore require a range of institutional and societal responses, including addressing service gaps, providing practical responses to cultural aspects of service provision, and continuing to work towards reconciliation. A major deficit was found in the training and support available to practitioners caring for terminally ill Aboriginal people. Addressing this requires a policy shift by health care institutions. The most useful training interventions included directing non-Aboriginal workers toward local sources of cultural information, dispelling myths and stereotyping and assisting in exploring ethical issues arising from cross cultural conflict. Practitioners also needed support both in analysing difficult care situations so as to arrive at practical management solutions and in debriefing their emotional responses. This would reduce the stress of providing cross cultural terminal care and improve service delivery. Palliative care in Central Australia can only be developed with input from both Aboriginal and non-Aboriginal participants. It cannot be progressed without the guidance and support of Aboriginal workers and community members, which requires Aboriginal empowerment at all levels of planning and decision making. This reflection on the nature of cross cultural terminal care, from the viewpoint of professionals within the majority culture, will contribute to the development of a culturally safe practice for working with Aboriginal colleagues and clients.

Wan, Xinan. "Epidemiology of hepatitis B infection in the Northern Territory of Australia". Thesis, The University of Sydney, 1994. https://hdl.handle.net/2123/26716.
Testo completoAbstract (sommario):
From August 1989 to may 1993, extensive studies on the epidemiology of hepatitis B virus (HBV) infection in the Northern Territory were conducted by means of community-based surveys, morbidity and mortality data review and mathematical modelling. The incidence of clinically apparent acute HBV infection in the Top End was 12 per 100,000 per annum, with a marked ethnic difference between Aborigines (42 per 100,000) and non—Aborigines (4 per 100,000), and an odds ratio of 10.4 (95% confidence intervals 3.2-33.8). Sixty percent of Aboriginal cases of acute hepatitis B occurred in children less than 10 years of age, whereas non-Aboriginal cases occurred in adults aged 20-29, mostly with behavioural risk factors. These findings confirm the importance of immunising Aboriginal children to reduce the future incidence of hepatitis B infection and hepatoma.
Average incidence rate of primary hepatocellular carcinoma (PHC) was 5.2 per 100,000 for the Aboriginal population and 0.5 per 100,000 for the non-Aboriginal population, giving a relative risk of 10.4 (95% confidence intervals, 4.0—26.7). However, the incidence of PHC was not significantly different between Aboriginal Australians aged 40 and over (30.9 per 100,000) and persons from high risk areas such as Southern Europe, Asia or the Pacific (18.9 per 100,000) (X2l = 0.97, P > 0.05). PHC was more frequent in males (2.3 per 100,000) than in females (0.7 per 100,000), with the relative risk of 3.4 (95% confidence intervals 1.3—9.3). The incidence of PHC increased with age in Aboriginal and non—Aboriginal people; the trend was statistically significant in Aborigines (X2l =. 4.74, P < 0.05) but not in non-Aborigines (X2l = 3.43, P > 0.05). The study showed that 63.6% of Aboriginal cases and 50.0% of non-Aboriginal cases of PHC had evidence of hepatitis B surface antigen positivity. This prevalence of the virus in Aboriginal patients with carcinoma (63.6%) was much higher than that seen in Aborigines from community-based surveys (13.1%) (X2l = 21.7, P < 0.001). The results indicate the importance of hepatitis B in the aetiology of PHC in Aboriginal people, and the importance of immunisation for its prevention.
Serological markers of HBV infection were detected in 28.7% of‘school children (46.9% of 439 Aborigines, 13.7% of 556 children from the "low prevalence" groups and 32.1% of 109 "other" ethnic groups). There was evidence of HBV infection in 12.8% of school staff from "low prevalence" ethnic backgrounds and in 37.9% of teachers from other ethnic (including Aboriginal) backgrounds. in Northern Territory schools, the prevalence of HBV infection is high in children and school staff from ethnic groups previously known to be at higher risk of HBV infection. For students and staff from ethnic backgrounds expected to be at low risk, HBV prevalence is greater than in individuals from similar backgrounds in other parts of Australia. These data suggest that horizontal transmission of HBV occurs in school settings in the Northern Territory, and strengthen the rationale for HBV immunisation of all children and staff at schools. Such a policy would also be applicable to other situations where there is contact between ethnic groups with high and low rates of HBV infection.
The immunogenicity of a recombinant hepatitis B vaccine (Engerix B) was examined in Aboriginal children four years after the introduction of universal vaccination for Aboriginal infants. Among 612 vaccinees, 375 (61.3%[95% confidence intervals 57.3% — 65.1%l) seroconverted (anti—HBs titres greater than or equal to 100 mIU/ml). There was a rapid decline in anti-HBs levels in Aboriginal children with time since immunisation; 7.8% of children appeared to revert to seronegative status for each year that had elapsed since the first vaccine dose. The overall response to hepatitis B vaccination in Aborigines was less than in other reported groups; this may be due to cold-chain failure in specific communities, to impaired responses reflecting malnutrition and genetic influence, and to titres which fall more rapidly over time.
Multivariate analysis showed that geographic region, increasing birthweight and delayed timing of the first vaccine dose after birth were predictors of increased antibody response to the vaccine; but that timing of the second and third doses did not significantly affect response. These findings have practical implications; firstly, the considerable flexibility in timing of hepatitis B vaccine doses makes it possible to integrate this vaccine with other childhood vaccines and to resume vaccination schedules when vaccinees miss the second or third doses; secondly, there is a need to evaluate the requirement for a booster dose of vaccine in Aboriginal children; and to improve the cold chain in those communities where seroconversion rates were lowest.
Epidemiological models were used to estimate rates of horizontal and vertical transmission of hepatitis B virus in a mixed race Australian community.

Testo completoAbstract (sommario):
Detailed facies analysis and sequence stratigraphic principles applied to outcrop and subsurface data have aided in the development of a reservoir geological
model for the Pacoota P3B Unit at the Mereenie Field, Central Australia. Mereenie is a linear Northwest/southeast trending oil and gas field 4 km wide and 35 km long, and covers an area of approximately 130 km2. In this field, oil and gas are produced from
some of the oldest known petroleum reservoirs in the word: reservoirs approximately 500Ma.
The Ordovician Pacoota P3B Unit, is part of an overall transgressive succession which records the transition from non-marine to marine environments in the northeastern margin of the Amadeus Basin. This transgression was punctuated by episodic events of rapid sea level rise and periods of sea level fall. The resulting vertical succession consists of three Fourth-order deltaic sequences formed by the regular alternation of sand-prone, non-marine sediments with marine mud/sand-prone deposits that prograded northeast as the basin subsided. Unlike previous investigations, this study recognizes four distinct types of sandstone facies associations within the broad braid delta system that characterizes the Pacoota P3B Unit. Facies Association 1 records the depositional characteristics of a
distal braid plain that was dominated by episodic sheetflood events. Facies Association 2 reflects a sudden change in fluvial style from fine-grained sheetflood
lobes to a coarse to pebbly-grained braid-delta system during a short-lived regressive phase. With time, this basal braid-delta system evolved into a tide-influenced braid plain indicating a transgressive phase. Facies Association 3 records the abrupt change from fluvial to tidal processes. This association is interpreted as the product of a tide-dominated delta front that prograded northeast. The palaeoenvironment of Facies Association 4 is interpreted as the fill of a wide incised fluvial valley system,
which marked the end of fluvial sedimentation at the margin of the Amadeus Basin
during the Ordovician. This association is capped by the transgressive marine deposits
of the Pacoota P3A Unit. These four facies associations represent a complex network
of depositional environments that results from the deposition of superimposed sandy, deltaic systems affected by tidal currents. The vertical facies evolution is punctuated by erosional sequence boundaries.
The development of a detailed stratigraphic framework allows the Pacoota P3B Unit to be subdivided into five correlative intervals that define reservoir
compartments in the Mereenie Field. These reservoir compartments are bounded by key stratigraphic surfaces and represent the lowstand (LST), transgressive (I'ST) and highstand (HST) systems tracts of the Fourth-order sequences defined within the P3B Unit. Maximum reservoir quality is associated with amalgamated fluvial sandstones
that define the LST of each sequence. Marginal to impermeable reservoir characteristics occur within the tidally-influenced TST and HST. From base to top
reservoir intervals are: P3-250, P3-230, P3-190, P3-150 and P3-120/130. Of these, the lowstand P3-120/130, P3-230 and P3-250 Reservoir Intervals are the most
prolific producers. The transgressive to highstand P3-150 and P3-190 Reservoir Intervals are considered as not economically profitable for hydrocarbon exploitation.
Petrophysical characterization of lithofacies types observed in the succession indicate that within each compartment, depositional facies exert the primary control on reservoir properties. Flow units are associated with tabular, cross-bedded sandstones. Permeability barriers are associated with bidirectional cross-beds, parallellaminated sandstones, soft-sediment deformed sandstones and bioturbated beds. During transgression the upper part of the lowstand fluvial system was sheared off resulting in a transgressive surface capping the fluvial deposits. Reworked fluvial
sediments were redeposited as reversing tidal flows above the lowstand intervals. These deposits, interpreted as neap-spring tidal cycles, consist of alternating sand and
silt/mud and bioturbated beds. In this setting, intense bioturbation generate sediment mixing destroying the reservoir properties of this interval. Additionally the areally continuous and impermeable silt/shale intervals of the tidal deposits contributed to the vertical barriers to flow in the reservoir. This study illustrates how facies analysis and high resolution sequence
stratigraphy can be applied to improve reservoir characterization in fluvio-marine successions deposited before the existence of land vegetation. In the Mereenie Field, these concepts have been successfully applied to: i) recognize with confidence all correlative reservoir intervals and ·ii) identify, orientate and map the LST of the Fourth-order sequences which represent the major reservoir intervals of the P3B Unit.

Hodgson, Renata. "Perceptions of authenticity : Aboriginal cultural tourism in the Northern Territory". Thesis, View thesis, 2007. http://handle.uws.edu.au:8081/1959.7/32902.
Testo completoAbstract (sommario):
Since the 1970s there has been a growing interest in Indigenous cultures globally. In Australia, the recognition that Aboriginal art and culture represents a distinct component of Australian identity has resulted in increased promotion of Aboriginal cultures and heritage sites as unique tourist attractions, mainly since the 1990s.
Research indicates that there is a significant international interest in Australian Indigenous cultures. In particular, it has been suggested that tourists want to experience ‘real’ Aboriginal culture and that they desire ‘authentic and genuine’ Aboriginal cultural experiences. Despite the fact that the concept of authenticity remains important to the different stakeholder groups of Aboriginal tourism, including tourists, tour operators and promoters as well as State/Territorial Governments, limited understanding exists as to what ‘authentic’ Aboriginal culture and, in particular, ‘authentic’ Aboriginal tourism experiences constitute in the minds of these stakeholders. Whilst an abundance of research exists that has addressed the issue of authenticity in different tourism settings, the majority of studies have treated the concept of authenticity as something given and have used quantitative tools to analyse the authentic-inauthentic binary. However, research utilising such methods has failed to uncover the different perspectives and meanings respondents may hold of the notion of authenticity. Notably, the perceptions of authenticity in Indigenous tourism have received little attention. The few existing studies on authenticity in Indigenous tourism settings have given emphasis to differing agendas, and have therefore provided only a piecemeal understanding of how authenticity is perceived and interpreted by the different stakeholders of Indigenous tourism. More importantly, research on Aboriginal hosts’ perceptions of authenticity is virtually non-existent. Yet, clarification of how tourists and hosts perceive authenticity in Aboriginal tourism is essential when addressing issues of accreditation and branding as well as key marketing objectives that aim to promote ‘authentic’ Aboriginal tourism experiences.
This study seeks to address the gaps within the tourism literature surrounding authenticity in Aboriginal tourism. The aim is to understand the concept of authenticity in Aboriginal tourism from a stakeholder perspective. The study is guided by two main research questions: What are the perceptions of authenticity of tourists as well as tour providers and their employees? and Are theoretical perspectives of the notion of authenticity shared by those stakeholders? More specifically, this study investigated five important issues: 1) tourists’ perceptions of authenticity at three different Aboriginal cultural tours; 2) the perceptions of three Aboriginal cultural tour operators and their employees in regard to authenticity; 3) whether there were any discrepancies and/or similarities between the perceptions of tour operators/employees and tourists about what constitutes an authentic Aboriginal tourism experience; 4) whether any of the different theoretical perspectives of authenticity were shared by tourists and tour operators/employees; and 5) whether a conceptual framework could be developed that provides an overview of salient elements explaining the formation of perceptions of authenticity within Aboriginal cultural tourism experiences.
In order to examine the research questions a qualitative research methodology grounded in the constructivist paradigm was adopted. This paradigm was chosen as it reflects the exploratory nature of the research and allows for flexibility throughout the research process. This study utilised qualitative in-depth semi-structured interviews as the primary data collection method together with participant observation. Data was collected from 92 interviews, consisting of 72 tourists and 20 employees, within three Aboriginal cultural tour companies in the Northern Territory. The three different Aboriginal cultural tours chosen for the purpose of this study were: Tiwi Tours at Bathurst Island, Manyallaluk Aboriginal Cultural Tours near Katherine and Anangu Tours at the Uluru-Kata-Tjuta National Park. The results of this research revealed that respondents hold multiple constructions of the notion of authenticity. In general, however, most respondents associated an authentic Aboriginal cultural tour experience with a genuine experience which does not feel contrived, staged or ‘plastic’. In particular, the study found that respondents’ perceptions of authenticity can be grouped into four elements. The first element consisted of the background and role of the Aboriginal tour guide, which was found to be a major factor influencing respondents’ perceptions on whether the tour was offering an authentic experience. The second element is characterised by the tourists’ search for ‘real’ and ‘genuine’ Aboriginal people. Here, respondents equated authenticity with the opportunity to visit a ‘real’ Aboriginal working community and to be able to experience Aboriginal people in an everyday setting. Respondents were found to hold preconceived notions and images in their minds as to who ‘real’ Aboriginal people are and what their ‘authentic’ lifestyle should involve. In addition, the majority of respondents defined authentic Aboriginal culture as the contemporary culture of Aboriginal people. Consequently, an authentic Aboriginal cultural tour experience was conceived in terms of gaining an insight into the contemporary lifestyle of Aboriginal people.
The third element that contributed to the experience of authenticity is associated with having the opportunity to see and/or purchase authentic Aboriginal arts and crafts. Respondents perceived a product as authentic if it conformed to specific criteria, such as reflecting uniqueness and originality and being handmade by a local artist.
Verification of authenticity was also generated by the shopping experience itself, for example meeting the artist and watching how the craft is produced. Finally, the fourth element in the construction of authenticity is related to tourists’ perceptions of the dance performance. Some respondents recognised this as a contrived experience that lacked ‘traditional’ authenticity, while some respondents wanted to see an authentically contrived or staged cultural performance as this was regarded as an occasion for entertainment and enjoyment. Furthermore, the findings of this study suggested that respondents generally referred to the authenticity of toured objects (object authenticity) when describing their perceptions of an authentic experience. The majority of tourists and employees employed a constructivist approach within their conceptualisation of the notion of authenticity. Only a small number of tourists appeared to hold attitudes similar to the objectivist and postmodern perspectives.

Testo completoAbstract (sommario):
From 1901 until 1968 the Commonwealth bureaucracy essentially ran the Northern Territory. The way the Territory was administered was dictated by the remoteness of the Government and the difficulty in communications, both within and outside of the Territory. This power facilitated a situation which pitted the dominant colonists and bureaucracy against the Aboriginal peoples in a conflict over scarce resources. The pastoralists required water for the stock; the Aboriginal Peoples required water to survive; the pastoralists and the miners needed cheap labour. Various methods were employed to discipline the People on the pastoral properties—provide ration stations designed to attracted the People from the wild and seduce them into a sedentary lifestyle; harassment by the police and an incomprehensible legal system administered in a foreign language; hound them into ‘reserves’, a euphemism for land that was seen as of no use to the colonisers or their stock. Finally assimilate them into the dominant race through a form of eugenics. My research transported me from expecting a simple ‘documentary reality’ relationship between the bureaucrats and the Aboriginal peoples towards a more conspiratorial connection between the dominant class, the bureaucracy and the Aboriginal Peoples. Paradoxically, these same pastoralists and miners were dependent on Aboriginal labour to enable their enterprises to be viable. To this end the bureaucracy administered laws that controlled standards of habitation, provision of food and clothing, and wage rates provided to the Aboriginal workers. The pastoralists and the miners observed such provisions in the breach, but other provisions controlling: where the Peoples could work and who they could work for, who they could marry, and where they could go were implemented assiduously. Working and living conditions for all but the Peoples in the most remote areas were bad to say the least.
In the administration of the law the actions of certain police were horrific by any measure and the Supreme Court under Judge Wells made a mockery of justice and court procedures. The most celebrated case to come before the worthy judge was that of R. v Tuckiar, which was later appealed on the grounds of the judgement and court proceedings and gave rise to scathing criticism by the High Court Judges in unison.
Of course, the ultimate expression of conflict between the bureaucracy and the Aboriginal Peoples was the doctrine of assimilation. This doctrine was designed to actively absorb the Aboriginal Peoples into the general Australian population along with their culture and languages. Resulting from a selective form of eugenics the so-called ‘stolen generations’ and its undesirable results have emerged. This thesis records much of that conflict through the eyes of the bureaucracy and to a lessor extent the Aboriginal Peoples themselves.

Testo completoAbstract (sommario):
Koolpin and Jim Jim Gorges are narrow, bedrock channels developed in resistant sandstone of the Arnhem Land Plateau, Northern Territory. The tropical monsoonal climate results in rare flood events of great magnitude. Peak flow-rate estimations from rainfall of variable recurrence intervals, step-backwater flow-modelling, empirically derived boulder-transport equations and the use of fine-grained slackwater accumulations, as palaeodischarge indicators, allow quantitative estimates to be made
of the magnitude of the most geomorphically -significant flows. For events with an average recurrence interval of 100, 1000 years and the maximum probable flood-discharge that the gorges experience range from approximately 2000m3Is to 6500m3Is. Channel velocities, unit stream power and bed shear-stress are also high. Additional indicators of intense flow are the presence of potholes and flutes on bedrock surfaces. The boulder fields found within these gorges provide a means of energy dissipation and their location corresponds with reductions in unit stream power within the reaches. This relationship appears to represent a self-regulation system similar to the pool-riffle sequence in alluvial channels. It is probable that the
geomorphology of these gorges is deformable on the time scale of extreme events

Testo completoAbstract (sommario):
This thesis examines recent Aboriginal land tenure reform in the Northern Territory of Australia. The Commonwealth and Northern Territory governments have introduced three reforms since 2006: Township Leases, 5-year Intervention Leases and 40-year Housing Leases. Each of the reforms provides for the grant of a “head-lease” on land owned under the Aboriginal Land Rights (Northern Territory) Act 1976 (Cth) to a government entity, which then has the power to issue sub-leases to Aboriginal and non-Aboriginal persons.
Scholars have tended to focus attention on the first two reforms, the Township Leases and the 5-year Intervention Leases, and the extent to which they have been successful or otherwise in achieving their policy objectives. Scholars have also tended to interpret one policy objective associated with all three reforms – the so-called “normalisation” of Aboriginal communities – as having a static meaning, often criticising it as a return to the Northern Territory’s colonial past.
This thesis takes a different approach, attempting to examine the legal structure of all three reforms as part of wider discourse surrounding Aboriginal land tenure reform in the Northern Territory. I first analyse the legal structure of the reforms as evidenced in legislation and policy documentation, and then qualitatively examine the meaning of the term “normalise” in parliamentary hansard. My analysis reveals that the meaning of the word “normalise” has shifted since the first reform was introduced, and this change has been reflected by a parallel change in the legal structure of the reforms. The first two reforms (Township Leases and 5-year Intervention Leases) exhibit some parallels with the Northern Territory’s colonial property regime. However, the 40-year Housing Leases do not appear to possess the same characteristics and in fact may result in traditional Aboriginal owners of land in the Northern Territory exercising greater legal and economic control over their land.

At the time of its inception in 2008, the Strategic Indigenous Housing and Infrastructure Program (SIHIP) was the largest indigenous housing program in Australia's history. SIHIP represented a $672million investment by the Australian and Northern Territory governments to improve housing in 73 remote and widely scattered indigenous communities in the Territory. Emerging at a time when indigenous issues shot to the forefront of national politics, SIHIP was billed as a response to the widespread overcrowding, poor housing quality, and lack of job opportunities that has come to define many remote communities in the Territory. Faltering out of the gate, SIHIP quickly came under criticism and became a symbol of government excess and ineptitude. A review of the program refocused SIHIP, which has since met its housing and employment targets. However, this thesis will demonstrate that these targets do not reflect the overall impact of SIHIP on target communities. This thesis will look at SIHIP in a new light and illustrate that, beneath a seemingly straightforward construction project, are tremendous underlying forces of distance and control. SIHIP's legacy will not be reduced overcrowding and improved housing outcomes, rather, it will be the reshaping and condensing of indigenous settlement patterns and an unprecedented increase in government control over indigenous housing. Not only is it a break with indigenous housing policy over the last 40 years, SIHIP also follows the larger historic pattern of providing housing and services as a means to control indigenous settlement. This thesis will tell the story of SIHIP through the two lenses of distance and control and analyze the role of these forces in shaping SIHIP, its impact on the ground, and its legacy. Through reframing the debate around SIHIP, this thesis will draw broader planning lessons about the challenges of planning across distance and the complex dynamics that influence large, government-driven initiatives. Furthermore, it will illuminate key opportunities that have emerged through SIHIP, many of which have received little public attention. Through this analysis the core assumption of SIHIP is challenged, leaving the question: is housing provision the best way to improve living conditions for Australia's indigenous population?

Testo completoAbstract (sommario):
The Northern Territory is a unique jurisdiction that defies the Australian average in many ways. Recently, the smallest economy in the nation has experienced strong economic growth due to the expansion of the resources sector. The neoclassical growth model which was pioneered by Robert Solow (1956) proposes that sustained economic growth is almost entirely dependent on productivity growth. The central question becomes whether or not the Northern Territory’s remarkable economic growth is sustainable in the long run. To answer this question the thesis estimates total factor productivity growth for the Northern Territory using the methodology employed by Krugman (1994) and Young (1994). This is accompanied by an outline of the model and its assumptions, a review of similar studies, and a trend analysis of key economic indicators for the Northern Territory. The thesis will then explore the policy implications of the findings.

Testo completoAbstract (sommario):
This thesis examines a leading group of Chinese merchants (those engaged in overseas trade) and their families who operated businesses in the Northern Territory (‘the Territory’) during the period 1880-1950. This study emphasises the benefits of a translocal approach to understanding the interrelationships of race, class, and gender in this history. But it also provides a framework for investigating the interrelationships of Chinese people in Darwin, of Chinese and Aboriginal people, and of Chinese people in different locations in Australia and overseas. I argue that Chinese merchants and their families based in particular locations should be studied in relation to each other and thus comparatively and transnationally to better understand their various contributions to local, national and international histories. Darwin is one such illuminating example. The Chinese merchants in the Territory are a dynamic and underinvestigated case study in this regard due to several compelling factors. The ongoing presence of Chinese in the Territory spanned a tumultuous era in the Territory and Australia’s path to nationhood: the discovery of gold in the Territory in the 1870s; the advent of the telegraph line, railway and international steamship companies; anti-Chinese sentiment in Australian colonies and overseas in the 1880s; Federation and the infamous Immigration Restriction Act in 1901; the passing of the Territory from South Australian to Commonwealth administration in 1911, and World Wars One and Two. Darwin occupied a pivotal position in Australia’s battle with Japan during World War Two. Moreover, the Territory, together with the northern regions of Western Australia and Queensland, featured in race debates and anti- Chinese rhetoric surrounding Federation. These regions posed a dilemma for Australian colonial then federal governments regarding the need for labour to develop the north without compromising the vision of a ‘White Australia’. Until 1888, the Territory was an ‘open door’ to Chinese immigration. Furthermore, the Territory’s dominant Chinese population affords a manageable but revealing in-depth historical analysis of a microcosm of Chinese of various dialect groups, classes, and occupations. As will be shown, this microcosm was organised and directed by a group of Darwin-based merchants. Darwin was a key node for European and Chinese merchants in the circulation of goods and people, aided by steamships and the telegraph. The tropical climate and challenging terrain prompted authorities to work with Chinese merchants to import labour. Chinese merchants established businesses in the Territory; some had transnational business networks, sometimes in conjunction with Chinese merchants in other parts of Australia, that contributed to economies beyond Australia to the Asia-Pacific. In contrast to mainstream assumptions about the marginalisation of Asians in ‘White Australia’, I demonstrate that in the Territory, Chinese merchants and their families experienced a degree of respect and acceptance from European political and business elites as leaders and representatives of the Chinese. They were also part of the Territory’s complication of global histories of race through the triangulation of European-Chinese-Aboriginal relations. These relations were policed by government regulations but afforded Chinese merchants elevated social status over other Chinese and over Aboriginal people, some of whom were employed by Chinese merchants, a practice later prohibited by law. The considerable political activism of the Territory Chinese leaders on behalf of the Territory Chinese against anti-Asian discrimination is also highlighted in this case study. The economic competitiveness of the Chinese merchants in the Territory was a major factor in the formation of an anti- Chinese faction of European businessmen in the Territory. This faction campaigned for national immigration restrictions in the lead-up to the passing of similar Chinese immigration restrictions by Australian colonies in 1888 and during the formulation of the 1901 federal Immigration Restriction Act. Territory Chinese merchants actively protested these and other ‘White Australia’ policies, producing valuable records of Chinese voices. These records also provide evidence of European support for the Chinese, an aspect of history rarely discussed then or since. My investigation of this aspect of European-Chinese relations places it in critical relationship to the interplay of issues such as the politics of citizenship, the economic agendas of governments and interpersonal exchanges ‘on the ground’. Finally, this case study contributes to another important and developing field of research – the history of Chinese women in Australia. Underused archival sources disclose numerous examples of Territory Chinese women from merchant families who became involved in business despite Australian and Chinese gender norms that restricted women’s activity. Two women who will be profiled in this study even self-identified as merchants. This translocal study of the Chinese merchants of the Territory adds considerably to our understanding of the history of the Territory, of the development of Australian nationhood, and of transnational political, economic and social histories. It is also a study of personal significance in exploring the experiences of my ancestors as the first generation to migrate to Australia. Additionally, being a descendant of one of the merchants and one of the remarkable merchants’ wives presented in this study has given me access to family archives which have been invaluable to my research.Thesis (PhD Doctorate)

Testo completoAbstract (sommario):
Over the past decade, national testing in literacy and numeracy for primary and junior secondary education reveals NT remote Aboriginal children have consistently performed at a much lower level than all other groups across Australia. This performance is situated within a broader and stratified education system, of which ongoing education reforms have failed to address. This entrenched pattern by wealth has NT remote Aboriginal students located at the bottom of this layering, underpinned by an Aboriginal racial identity as a defining characteristic. For NT remote Aboriginal families this layering is bound within a deepened embeddedness of racism, interacting with an economic ordering that has relegated NT remote Aboriginal families to a life of socially–constructed marginalisation, on their own lands. This study applies Critical Race Theory (CRT) as a primary tool of analysis, Aboriginalising its tenets to respond to the unique narrative of NT Aboriginal education. Drawing on research with remote North Australia Aboriginal principals (head teachers), Aboriginal communities and educators, critical race methodology is used to explore the intersecting roles of colonial history, ‘race’ and wealth inequality in the construction and deployment of NT remote Aboriginal education inequality. This investigation privileges the voices and Stories of Northern Territory remote Aboriginal families, strengthened through my lived Aboriginal experience of 25 years employment as a teacher and senior education administrator in Northern Territory urban and remote communities. In this study, the CRT tenet of interest convergence/interest divergence is utilised alongside Indigenous CRT frameworks. Underpinning this study, a form of NT remote Aboriginal social capitalism is shown to be at the epicentre of a progressive NT remote Aboriginal education policy architecture, wrapped around Indigeneity and its existential dimensions, as a foundation to improving the pattern of NT remote Aboriginal education performance.

Testo completoAbstract (sommario):
This study researched two major aspects of the primary school principalship in the
Northern Territory and Australian Capital Territory viz., (1) How current trends in
educational governance have affected the role of the principal, and (2) Assessment and
selection procedures used for promotion to the principalship in the present educational
environment.
The context of the study has been outlined by presenting a brief historical and
organisational overview of public education in both Territories, along with an
examination of the literature on recent trends and issues in educational governance and
promotion procedures.
The research methodology used to examine the questions posed in this study is
qualitative or descriptive in nature. The data was collected through the use of a semistructured
interview technique and represents the ideas, opinions and perceptions of a
specially targeted group of principals and aspiring principals from both education
systems.
The findings demonstrated that many aspects of the role of the primary principalship in
the N.T. and A.C.T. are changing, due to a new set of values in educational policymaking
and increased political control. There was a high degree of similarity between
respondents in each Territory in regard to how the role is being reshaped.
It was also found that the level of support provided by both systems to assist principals
in coping with the changes has been inadequate and that the changes have led to a
degree of conflict and new job-related pressures for most primary school principals.
It was concluded that assessment and selection procedures should be rigorous and
demanding, commensurate with the significance of the position. In this regard both
educational systems need to improve present procedures by addressing perceived
weaknesses. To this end assessment centres may have a role to play.
Finally, further implications of the conclusions are addressed in terms of the necessity
for thorough preparation and training of aspirants to the principalship to enhance their
chance of selection and help them cope with the new expectations and demands of the
position. This responsibility should be shared between the aspirant, professional
associations and the employing education department.

Testo completoAbstract (sommario):
Cultural resource management is an effort to revitalize culture in the present, and the aim of such endeavours is to provide stability for future generations in navigating culture. This theme runs throughout my preliminary fieldwork in Wadeye, as I sought to collect traditional narratives of the mythic “Dreaming” song cycles. One of the goals of my volunteering and fieldwork in this region was to help make history relevant to future generations of Aboriginal Australians by providing them with resources from the local Kanamkek-Yile Ngala museum. In this thesis, I explore how culture as presented in traditional myths and narratives becomes intertwined in the daily lives of Aboriginal Australians. The thesis delves heavily into the process of fieldwork as a way of engendering empathy for the social analysis of myths. The experience of the field, entering into another way of life, is central in forming an understanding for how myth and narrative play vital roles in Aboriginal Australian culture. The fieldwork here is largely from the vein of applied anthropology in seeking answers relating to the loss of narratives in the region. The drive here is to find a framework for the successful revitalization of lost stories by visiting cultural sites and reconnecting to experiences of the land. I also explore notions of ethno-poetry as a possible way of tapping into the creative potential of the Aboriginal Australian “Dreamtime.” The aim is thus to engender larger discussion in cultural resource management by centering the community in deciding its own responses and adaptation strategies in dealing with story revitalization efforts.Graduate Studies, College of (Okanagan)

The impact of recent climate change on permafrost distribution was evaluated by repeating the 1964 survey of Roger Brown along the Alaska Highway from Whitehorse, YT to Fort St. John, BC in August 2007 and 2008. Results demonstrate that: (1) significant degradation of permafrost has occurred over the past four decades, especially in the southernmost part of the route where 67% of the permafrost sites in 1964 no longer exhibit perennially frozen conditions; (2) the mapped southern limit of discontinuous permafrost appears to have shifted roughly 75 km northward; (3) most of the permafrost still present in the study area is in peat or under thick organic mats, which probably relates to a large thermal offset or to the latent heat requirements of thawing permafrost; and (4) that where permafrost has persisted, it is very thin, discontinuous, at temperatures just below 0°C, and its location may relate in part to the existence of atmospheric temperature inversions in the region. Changes in permafrost are attributed to significant climatic warming, primarily in winter, at rates of 0.4°C to 0.5°C per decade from 1965-2008. The results augment the very limited number of field studies of long-term change to permafrost in Canada, and are relevant to northern residents who must adapt to changing permafrost conditions.

Testo completoAbstract (sommario):
Background: Indigenous Australians have lower breast cancer rates but higher mortality rates compared with other women. With evidence of ethnic variations in MD globally, investigating MD in Indigenous women may provide insight into optimising diagnosis and care for an underserved population. Aims: To investigate the MD and BreastScreen attendance of Indigenous and non-Indigenous women in the NT and assess the diagnostic efficacy of radiologists in cases with varying breast densities. Methods: Indigenous status, age, postcode, HRT, family history of breast cancer, symptoms and language spoken at home from self-reported 857 Indigenous and 3236 non-Indigenous women were analysed for associations with MD (study 1) and screening attendance (study 2). ROC analyses were used to determine cut-off points for age and numbers of screening visits. Logistic regression analyses were used to determine odds ratios and p≤0.05 were considered significant. In study 3, mammography test scores of 273 radiologists were assessed on low MD (LMD) vs high MD (HMD) cases. Sensitivity, lesion sensitivity, specificity, ROC and JAFROC FOM were compared using Mann-Whitney U or unpaired t-tests. Results: MD was lower for Indigenous women. For non-Indigenous women, HMD was associated with ≤55 years of age, no family history of breast cancer, speaking mainly English, and living remotely. For Indigenous women, HMD was associated with younger age. Indigenous women have fewer visits to screening and non-English speaking was mainly associated for Indigenous women only. Remoteness was associated with fewer visits for non-Indigenous women only. Shared predictors were ≤55 years and no family history of breast cancer. Radiologists had better lesion sensitivity and specificity in LMD vs HMD cases in 3 of 5 tests. ROC and JAFROC were better in LMD vs HMD cases for 1 of 5 tests. Conclusions: Indigenous women have lower MD and lower attendance to BreastScreen than non-Indigenous women. Breast cancer detection is more effective in LMD cases indicating that Indigenous women would benefit from better program engagement given their density profile and high death rates from breast cancer.

Testo completoAbstract (sommario):
Water level, aquifer test, and slug-test data indicate that the Koongarra uranium deposit is within a low permeability, semi-confined, fractured-schist aquifer. Water levels demonstrate semi-diurnal and diurnal fluctuations related to earth tides and evapotranspiration stresses. Hydraulic test data were analyzed with homogenous isotropic and homogenous anisotropic models which allowed parameter estimation for sub-regions of the study area. Dominant anisotropy is subparallel to lithologic layering and the reverse fault. Slug tests reveal regions controlled by low storage but highly conductive fractures and isolated regions of low conductivity. Hydraulic connection of the weathered zone with the underlying schist is dependent on clay content and fractures. Environmental isotopes indicate ground water has been isolated from the atmosphere for at least 40 years and possibly several thousand years in some locations. Water budget calculations indicate the majority of recharge must be from direct infiltration through the weathered profile to account for the calculated ground-water fluxes.

Testo completoAbstract (sommario):
The Amadeus Basin is one of several sedimentary basins where evaporite minerals are located in Australia. The Karinga Creek Drainage System, Northern Territory,
which is situated in the eastern zone of the Amadeus Basin was the study area for this project. Sample cores of the evaporitic sediments from several playa lakes in
the study area were collected for chemical analysis.
The two main aims of the project were: (1) to chemically characterize these evaporitic sediments in an unleached and leached state; and (2) to assess the leachability of evaporite minerals such as gypsum, glauberite,
halite and thenardite under variable leaching conditions.
Other objectives of the work in this thesis covered:
(i) the development of new methodology for the determination of trace elements in the sediments using microwave heating, (ii) the determination of the major evaporite minerals present and their location in the sediments of selected playa lakes, (iii) the presentation of selected major, minor and trace elements as depth profiles for each core from the playa lakes under study,
(iv) the application of chemometrics to the collected data. The chemical analysis strategy developed to achieve these aims and objectives involved the use of many instrumental techniques such as x-ray fluorescence
spectrometry (XRF), atomic absorption spectroscopy (AAS), inductively coupled plasma spectroscopy (ICP), diffuse reflectance infrared Fourier transform
spectroscopy (DRIFT) and ion chromatography (IC).
XRF analysis of the core samples showed a wide variation in the major and minor components along the core profiles reflecting the depth of deposition of different
evaporite minerals. The predominant minerals found by DRIFT analysis were gypsum, glauberite, halite and calcite. The results of trace element analysis
showed that generally there were very low levels of heavy metals in the sediments.

Testo completoAbstract (sommario):
Over the last two decades, gold occurrences in the Palaeoproterozoic Pine Creek Orogen (PCO) have been cited as type-examples of high-temperature contact-metamorphic or thermal-aureole deposits associated with granitoid magmatism. Furthermore, spatial relationships between these gold occurrences and the granitoids have led to inclusion of these deposits in the intrusion-related gold deposit group. Research on the characteristics, distribution and timing of these gold deposits tests these classifications and supports an alternative interpretation. The deposits display many similarities to well-described ‘turbidite-hosted’ orogenic gold deposits described from several Palaeozoic orogens. As in most ‘turbidite-hosted’ orogenic deposits, the gold mineralisation is dominantly epigenetic, sediment-hosted (typically greywacke and siltstone) and fold-controlled. Most gold is hosted by concordant or discordant veins, with limited alteration halos in host rocks, except where they occur in silicate-facies BIF or other Fe-rich rocks. The domal culminations of major doubly-plunging anticlines, and/or fold-limb thrust-faults, are important structural controls at the camp- and deposit-scales. Many deposits are sited in parts of the lithostratigraphy where there is significant competency and/or chemical contrast between units or sequences. In particular, the complex interdigitated stratigraphy of euxinic and transitional high-energy sedimentary rocks of the c.1900-1880Ma South Alligator Group is important for the localisation of gold deposits. The distribution of deposits is influenced further by the location and shape of granitoids and their associated contact-metamorphic aureole. Approximately 90% of gold deposits lie within the ∼2.5km wide contact-aureole, and most of these are concentrated in, and just beyond, the biotite-albite-epidote zone (0.5-1.0km from granitoid), with few deposits located in the inner hornblende-hornfels zone. At the deposit scale, gold is commonly associated with arsenopyrite-loellengite and pyrite, native-Bi and Bi-bearing minerals, and is confined to a variety of extensional quartz-sulphide ± carbonate veins. Such veins formed typically at 180-320°?C and ∼1kbar from low- to moderate salinity, two-phase aqueous fluids. Isotopic studies of the deposits are equivocal in terms of the source of hydrothermal fluid. Most δD and δ18O values fall within the range defined for contact-metamorphic and magmatic fluids, and sulphur isotopes indicate that the fluids are within the range of most regional sources. Significantly, lead isotope ratios show that the goldbearing fluid does not have a felsic magmatic-source signature, but instead suggest a homogenous regional-scale lead source. Excluding a few outliers, the relative uniformity of deposit characteristics, including host rocks, structural style, alteration, sulphide paragenesis and fluid P-T-X conditions, suggests that most deposits represent a continuum of broadly coeval mineralisation that formed under similar geological conditions

Despite almost two decades of field research, historical archaeology in Australia continues to lack a unified theoretical purpose. Thepredominantly descriptive approach which has characterised much recent Australian work could be profitably replaced by an approach which is both archaeological and anthropological and which makes use of data from documentary and, where available, oral sources in addition to archaeological evidence. Such an
approach will achieve maximum usefulness in historical sites which are artefacts of early Aboriginal/European interaction. In the present study documentary, oral and archaeological research in the form of surface collection and mapping are combined at Imarlkba, a site produced by a period of European/Aboriginal interaction characterised by the term'fossickingeconomy'. Explanations for site formation processes and their locations are proposed through models derived from all three data sources, concentrating on an apparent dual system of garbage disposal, preferential
removal of material from the site by Europeans and Abori ginals and the distribution of artefacts such as wire twitches and coppiced trees. This brief study is dedicated to those participants in the fossicking economy, men and women, black and white, who contributed to Imarlkba's site formation

University of Western Australia. School of Earth and Geographical Sciences, 2003. http://theses.library.uwa.edu.au/adt-WU2003.0025.
Testo completoAbstract (sommario):
[Truncated abstract] The Northern Bonaparte Basin and adjacent Darwin Shelf form part of a major petroleum province on the northwestern margin of Australia. The middle to Late Cretaceous Bathurst Island Group consists of siliciclastic and pelagic carbonate strata that form the regional seal to underlying Upper Jurassic and Lower Cretaceous reservoir sandstones. The Bathurst Island Group has previously been subdivided into four stratigraphic sequences or ‘play intervals’ bound by regional disconformities in the Valanginian (KV horizon), Lower Aptian (KA horizon), upper Lower Cenomanian (KC horizon), Middle Campanian (KSC horizon), and at the CretaceousPaleocene boundary (T horizon). Correlation of these sedimentary packages and stratigraphic surfaces requires high-resolution calcareous microfossil biostratigraphy, while palaeobathymetric determinations based on benthonic foraminiferal assemblages are important for determining the subsidence history of the area and relative sea-level changes. This study presents the first detailed stratigraphic distributions, taxonomic lists and illustrations of foraminifera and calcareous nannofossils from the Bathurst Island Group of the Northern Bonaparte Basin and Darwin Shelf. A biostratigraphic framework has been constructed for the study area incorporating ‘standard’ (Tethyan) Cretaceous planktonic foraminiferal and calcareous nannofossil events where applicable, and integrating locally defined events where necessary. This framework allows Cretaceous strata to be correlated regionally across the study area and to the global chronostratigraphic scale. Correlation of the Northern Bonaparte Basin and Darwin Shelf strata to the Cretaceous Stages and international time scale is based on recent ties of nannofossil and foraminiferal events to macrofossil zones and palaeomagnetic polarity chrons at ratified and proposed Global Stratotype Sections and Points (GSSPs). Calcareous nannofossil events recorded in the study area that are critical for defining stage boundaries include the lowest occurrences of Prediscosphaera columnata, Micula decussata, Lithastrinus grillii, and Aspidolithus parcus parcus, and the highest occurrences of Helenea chiastia, Lithastrinus moratus, Aspidolithus parcus constrictus, and Eiffellithus eximius. Important planktonic foraminiferal events for correlation include the lowest occurrences of Rotalipora gr. globotruncanoides, and Dicarinella asymetrica, and the highest occurrences of Planomalina buxtorfi, Rotalipora cushmani, and Dicarinella asymetrica. During the middle to Late Cretaceous the Northern Bonaparte Basin and Darwin Shelf occupied mid-high palaeolatitudes between 35ºS to 45ºS. These palaeolatitudes are reflected in the transitional character of the planktonic microfossil assemblages, which combine elements of the low-latitude, warm-water Tethyan Province to the north and the cool-water high-latitude Austral Province to the south. ‘Standard’ Tethyan zonations are most applicable for uppermost AlbianMiddle Campanian strata because equator-to-pole temperature gradients were weakly developed, and global climate was warm and equable during this interval. These conditions resulted in broad latitudinal distributions for Tethyan marker species, and consequently most UC calcareous nannofossil zones and European-Mediterranean planktonic foraminiferal zones are recognised. In contrast, the EarlyLate Albian and the late Middle CampanianMaastrichtian were intervals of greater bioprovinciality and stronger palaeotemperature gradients. In these intervals application of the Tethyan zonations is more difficult, and a number of the Tethyan biostratigraphic markers are absent from the study area (e.g. Ticinella species in the Albian and Radotruncana calcarata in the Late Campanian). Cretaceous palaeobathymetric reconstruction of the study area is based on comparison of the foraminiferal assemblages with those of previous Cretaceous palaeobathymetric studies. Marginal marine assemblages consist solely of low diversity siliceous agglutinated foraminifera (e.g. Trochammina). Inner and middle neritic water depths (0-100 m) contain rare to common planktonic foraminifera (mainly globigerine forms), robertinids (e.g. Epistomina), siliceous agglutinates, lagenids, buliminids (e.g. Neobulimina), and rotaliids. The outer neritic zone (100-200 m water depth) contains abundant planktonic foraminifera (keeled and globigerine), calcareous agglutinates (e.g. Dorothia), and diverse lagenids, buliminids, and rotaliids. Upper-middle bathyal water depths (200-1000 m) are characterised by abundant planktonic foraminifera, common siliceous agglutinated taxa (e.g. Glomospira), rare to common Osangularia, and globular species of Gyroidinoides, Pullenia, and Paralabamina.

This is an ethnoarchaeological study of style in the visual arts of Aboriginal people living in the Barunga region of the Northern Territory, Australia. My main concern is the development of a practical framework for the analysis of style in indigenous visual arts. This framework integrates the notions of style, semiotics and social strategy in an attempt to deal with the dynamics of image creation and perception. The principal result is that the morphological characteristics of style are influenced systematically by the historically situated positions of both producer and interpreter and by the differing strengths, possibilities and constraints of different raw materials. Moreover, each raw material has inherent qualities that make it particularly suitable for specific social uses. Since different media within an artistic system are likely to exhibit a unique combination of stylistic characteristics, including differing degrees of diversity, it is incorrect to assume that a single art form will be indicative of an artistic system as a whole. My conclusions are that research needs to be focused clearly on the contexts in which archaeological art occurs and comparative studies need to compare like with like. Single explanations are unlikely to be sufficient since it is most likely that they tell only part of the story. In addition, seemingly anomalous evidence should not be discounted, but should be used as a basis for inquiry into the likelihood of alternative scenarios that coexist with the main explanation.

Testo completoAbstract (sommario):
The purpose of the research is to develop a widely acceptable and more holistic method for valuing traditional activities in a northern native community. It does this by extending contemporary valuation methods to include native categories and perceptions of natural resources, both past and present. The community of Old Crow, Yukon Territory is used as the field site because it is a relatively stable community, closely linked to the land, and one for which historical material is available.
Any assessment of a contemporary native community, its people, and their relationships to the land and its bounty would not be complete without an examination of their history. Thus, the thesis recounts the history of the Kutchin Indians of Old Crow. By reviewing past situations, traditions and cultural beliefs, the present day place of the land and its resources in the lives of the Old Crow people is revealed.
Contemporary valuation methods are defined as those which emphasize valuing resources numerically using a specific type of quantitative information. The more holistic method, on the other hand, includes the examination of the 'value'1 assigned traditional activities by the people themselves as exemplified through past and present situations. The ultimate goal of this work is to show that static quantitative analyses must be balanced with research into the more social side of native activities if their true value is to be found.
The thesis shows that contemporary valuation methods continually underestimate the 'value' of production from the land because they are usually limited in time and scope, and fail to deal with the non-market 'values' the land and its bountry hold for native northerners. It is discovered that comparing data collected at different points in time is a very effective means of precipitating out those 'values' which influence native people in making choices about the pursuit of traditional activities in the north.
Using this method the land and its resources as perceived by the Old Crow people are shown to still hold a paramount place in their day to day lives. As with other northern native groups, even though material opportunities and hunting strategies have changed, the people continue to value their traditional land and life for a variety of reasons.
While the thesis identifies the various 'values' associated with productive activities in Old Crow, it does not develop a scheme that quantifies or ranks the relative worth of these 'values'. It discusses the merit of the concept in the context of valuing activities in the traditional economy of the north, and concludes that much research is still required in this area.Arts, Faculty of

This biogeographical study documents the modern distribution of ostracodes in the southwest Yukon Territory and northern British Columbia, Canada. The study tested the hypothesis that dissolved ion composition and concentrations of the lake water are the primary determinants of the distribution of modern ostracodes in this region. A total of 28 freshwater species representing 8 genera were identified in the 33 study lakes. Species common in the southwest Yukon are widely distributed throughout North America, and include Cyclocypris ampla, Candona candida, Cypria turneri, Cypria ophtalmica, and Candona protzi. Concentrations of ostracode valves were highest in four lakes with moderate conductivity values ranging between 330 and 397 muS/cm. Rarefaction estimated species richness was low (3 to 8), and the highest estimated species richness was found in four lakes, three of which were within 1 km of each other. Conductivities in these lakes ranged between 320 and 397 muS/cm. There is little geographic pattern in either species richness or in the distribution of common species. The dissolved ion composition is the primary control determining the species that will be present in a particular lake.

The Northern Territory (NT) has a unique set of public health priorities due to its tropical climate, remote settings and high proportion of Indigenous people. In this setting I was placed as a Master of Applied Epidemiology (MAE) scholar within the Northern Territory's Centre for Disease Control (CDC) between 2012 and 2013. In this thesis, I present activities and projects undertaken at CDC which fulfil requirements of the MAE program. I discuss my participation in day-to-day public health activities of the CDC including surveillance of notifiable diseases and follow-up of people with infectious diseases. A large part of this role included responding to enquires from the general public and other health professionals; a requirement of the MAE program. I present two epidemiological projects, both of which conjointly fulfilled the requirement to analyse a public health dataset. In commencing the first project, I undertook a requisite literature review which identified the incidence of invasive group A streptococcal (iGAS) disease in Australia. My project comprised a case series in which I determined the incidence, risk factors, nature and outcomes of iGAS disease in the NT between 2011 and 2013. I found that incidence of iGAS disease in NT Indigenous and dialysis populations are amongst the highest reported. I presented these findings in an oral presentation at the 2013 Australian communicable diseases conference in Canberra. In a second epidemiological study, I undertook a cohort study to identify if refugees allocated to settlement in the NT between 2010 and 2011 received assessment and treatment (where indicated) for latent tuberculosis infection (LTBI). In investigating an acute public health problem, I participated in an investigation into an outbreak of notifications for Barmah Forest Virus (BFV) infection. We found the rise in notifications were due to an increase in false positive results from a widely used laboratory testing kit. A part of MAE requirements is to report on a project to a non-scientific audience. For this, I prepared a letter informing members of the public testing positive for BFV infection of our findings and recommendation for further follow-up. I present my evaluation of the tuberculosis surveillance system in Darwin which meets requirements to evaluate a public health system. I undertook a survey identifying firework-related injuries associated with annual "Territory Day" celebrations, when members of the public can legally buy and ignite fireworks. I published findings in the NT disease control bulletin. In fulfilment of teaching requirements, I prepared a 'lessons from the field' case study on 'how to write abstracts for conference presentation'. I facilitated discussion of this case study with my MAE peers. I present also my contribution to a workshop prepared and delivered by our MAE cohort to delegates attending the 2013 Australian communicable disease conference. We taught participants how to use EpiInfo7, a software tool with epidemiologic functionality. This thesis documents my MAE experience, fulfilment of requirements and findings of my investigations which benefit public health with a focus on vulnerable population groups of refugees and Indigenous people.

Testo completoAbstract (sommario):
The Tanami Gold Mine (TGM) is situated 600km NW of Alice Springs in the
Paleoproterozoic 'Granites-Tanami Inlier' of Northern Australia. The deposit, which was discovered in 1904 and has been mined intermittently since, is one of several gold-only deposits that occur in the inlier.
The host rocks to gold mineralisation at the TGM are a sequence of northwest-dipping, interbedded tholeiitic pillow-basalts and volcaniclastic-sedimentary rocks. The sediments were deposited by mass-flow mechanisms in a below wave-base subaqueous environment. The wholerock geochemistry of the basalts is similar to that of rift tholeiites, consistent with an intracontinental tectonic setting at the time of basalt eruption. The
presence of hematite and high-grade metamorphic detritus in the sedimentary lithologies is
also consistent with an intracontinental tectonic setting.
The deformational history of the Tanami area involved two sub-orthogonal episodes of
folding that generated northeast-trending Fl folds and northwest-trending F2 folds.
Interference between the two fold generations has created dome and basin interference
patterns. Illite-crystallinity measurements of sandstones and siltstones from the TGM
indic~te diagenetic temperatures, probably less than 250°C.
The metamorphic grade, intensity and number of deformations at the TGM are less than at
the 'Granites Gold Mine and elsewhere in the inlier. The host rocks to the mineralisation at
the TGM (Black Peak Formation) are therefore interpreted to be younger than at the
Granites (Ditjiedoonkuna Suite). Intracontinental rifting during the Palaeoproterozoic
Leichardt rifting event (1810-1740Ma) created a small rift basin into which the Black Peak
Formation was unconformably deposited onto a Archaean/Paleoproterozoic metamorphic
basement.
The Granites-Tanami Inlier is intruded by at least two distinct granite suites; the Mt
Winnecke Suite (1830-1815Ma) and the Gregory Suite (1800-1790Ma). The granites in
both suites are dominantly reduced, I-type granites that are enriched in incompatible
elements.
Gold mineralisation at the TGM is hosted within a complex sinistral wrench-fault array
and associated veins and alteration halos. The main mineralised faults trend approximately
NS and dip steeply east. Subsidiary structures trend at 030° and 070° and dip southeast.
Economic gold mineralisation occurs within quartz-carbonate veins and in the surrounding
sericite + quartz +pyrite± carbonate alteration halos. High-grade southeast-plunging,
oreshoots are present where the mineralised fault trends intersect. Detailed structural
studies indicate that the main mineralising event post-dated the bulk of F1 shortening, and
was synchronous with the emplacement of felsic dykes into the mine sequence. Stress inversion calculations, based on fault striation populations, have revealed that at the time
of the Au mineralising event, σ1 was sub-horizontal and SE-NW directed with σ2 subvertical.
This contrasts with the pre-mineralisation deformation which occurred under a
similarly directed σ1, but with σ3 sub-vertical. Flipping of the stress axes has allowed for
the formation of steeply-dipping faults that were effective fluid focussing zones during the
mineralisation event. A range of internally deformed vein textures and the presence of
crack-seal and extension veins are evidence for cyclic fault rupturing caused by variations
in the fluid pressure, shear stress and permeability of the fault zone.
Mass balance calculations undertaken on the sericitic alteration assemblages that are
spatially associated with Au mineralisation indicate addition of K, and volatiles (mainly
C02 and S), and leaching of Si and Na, which caused minor volume loss during the
metasomatic event. Fluid inclusion studies have revealed the presence of high-temperature
(300°C), low-salinity (5 wt.%) fluids with low C02 contents. Sulfur and oxygen isotope
data are consistent with a hybrid magmatic/contact-metamorphic origin for the ore-forming
solutions, which are inferred to be related to granite emplacement. During migration
through the footwall the fluids, partly re-equilibrated with wallrocks to acquire their
characteristic isotopic and geochemical compositions of δ34S≈12‰, δ18Ο≈10‰, K/Rb ≈
330.
Mineralising solutions were weakly.acidic (pH ≈ 5), reduced (S04≈/H2S ≈ 0.001) and
had a high ΣS content (0.006 molal); Gold was predominantly transported as AuHSO,
although Au(HS)2 may have also been important, particularly if the pH or ΣS was higher
than estimated. Gold deposition most likely occurred due to H1S loss associated with
sulfidation reactions as magnetite and hematite, present in the wall rocks, were altered to
pyrite. Phase separation occurring due to fluid pressure drops in dilational fault zones may
have also been locally important for gold deposition.
The ultimate source of gold at the TGM remains unclear. Two possibilities are suggested:
i) gold was magmatically sourced, and was partitioned into an exsolved magmatic-hydrothermal
fluid during magma crystallisation, or ii) gold was present as detrital gold in
the contact aureole of the granite and was scavenged and remobilised by magmatic and/or
contact metamorphic hydrothermal fluids. In the second scenario, Au mineralisation in the
underlying metamorphic basement may have provided a source of detrital gold in the
sedimentary lithologies of the Black Peak Formation.
