The proximate causes of many of the environmental issues facing residents of the Western Division are well known. Inappropriate land use practices (intensity, duration and timing of grazing), total grazing pressure, poor knowledge of ecosystem fragility and seasonal variation are some of the issues that contribute to an actual or perceived degradation of the landscape. Many of the current practices are seemingly at odds with the attitudes and values of the wider community and also those of the pastoralists who carry out these practices. This thesis seeks to explain this apparent contradiction. The thesis is composed of four elements. The first element reviews historical (mostly European) thinking about nature and the relationship between nature and society and traces how this thinking has changed through time. The second element is a review of the history of land settlement and land use in the division, and shows how the development of the division followed contemporary societal attitudes and values. The third element is an examination of the portrayal of landscape in a western visual art tradition and how this has the potential to be used to reflect contemporary social attitudes and values. The fourth element involves the use of three projects that used art and text as a basis for investigating the attitudes and values of people in the Western Division. The findings of the research indicate that visual landscape has the potential to become an aid in the identification of community attitudes and values about the landscape in which they live. Further, this technique allows for the emergence of other factors such as individual identity and its accommodation within the behavioural framework. In accommodating such factors as individual identity, individual and social attitudes and values toward the environment in any discussion of behaviour in relation to the landscape and its use, a better understanding of the motives underlying behaviour will be gained. In so doing better decisions can be made by both pastoralists and land administrators. Further research is needed to verify the usefulness of these findings in both opening up a positive dialogue with landholders and administrators and in aligning pastoralists’ behaviour towards a more sustainable land use ethic. / Doctor of Philosophy (PhD)

This study focused on the interactions between small skinks and their major predators/competitors (birds) and prey (arthropods) in core and edge areas of small, long established remnant Cumberland Plain woodlands of Richmond, New South Wales, Australia. Eight study sites were selected (4 edge and 4 core) within the peri-urban environment to compare the abundance and diversity of small skinks, birds and arthropods. Of the three taxa, only arthropods maintained a similar abundance and diversity between edge and core areas. Birds and skinks were either in lower numbers in the perimeter areas (skinks), or were interior/perimeter specialists (birds). Arthropod diversity and abundance of preferred skink prey, was also examined. It was concluded that the distribution of arthropod prey was similar between core and edge areas, and therefore, was not considered to have an influence on small skinks’ ability to inhabit edges. However, large, aggressive/noisy birds (including skink and small bird predators) dominated edge areas. Those birds encountered in the edge foraged in a variety of niches, such as on the ground or they swooped from vantage points. This, coupled with other anti competitor behaviour (e.g. noise, aggression, flocking), placed these birds in proximity to skinks in the edge areas. However, as most of these birds were also predators of skinks, it was concluded that the evidence supported a predator/prey relationship in the perimeter area, rather than a competitive one. This was supported by predation rates on skinks, using decoys. Birds preyed on small skink in greater numbers in the perimeter of woodland remnants than in their interior. This predation pressure was sustained throughout the year. It was concluded that predation and/or displacement of skinks and small birds resulted in lower numbers being observed in edge compared to core areas. This study demonstrated that old, small remnants not continually exposed to major disturbances (e.g. logging, agricultural practices) can re-establish stability in terms of environmental conditions. However, a stable environment or a single taxonomic group does not necessarily predict the response individual taxa will have to edge habitats and that this can alter the interactions between dependent groups such as prey/predator or competitors. . / Doctor of Philosophy (PhD)

The thesis is a historical study from a socio-legal perspective of debates about, and developments in, criminal investigation law in NSW since 1945. In that period, the NSW parliament has enacted extensive criminal investigation powers and safeguards. This can be seen as the result of the increasing political sensitivity of 'law and order'. Politicians have sought to exercise (and demonstrate) greater control over the criminal justice system. Legislation has been employed to provide a framework for police actions, and to define a role for others, including judges, magistrates and the Ombudsman. Political focus on law and order has also reversed the incentive structure for the police hierarchy. In the 1950s, there were strong incentives not to push for extra powers, lest policing practices and effectiveness receive unwanted scrutiny. In the 1970s, police were dragged into debate about their powers, in the face of the 'authorise and regulated' model suggested by numerous inquiries. More recently, police organisations have often initiated calls for new powers, in part to explain past failings. Another important factor driving debate and reform in recent decades has been the proliferation of oversight agencies, and academic insights that have debunked the 'rotten apple' paradigm. The Federal Government and Parliament have also been increasingly active in what would once have been considered purely State/Territory realms of criminal justice law and politics. These major influences have been coupled with a host of others, including the impact of a series of Royal Commission and law reform reports, the ongoing war on drugs, and the campaign against police verbals in the 1970s and 1980s. The examination of the forces that have influenced debate and reform yields other insights. For example, the complexity of the phenomenon of 'non-reform' is apparent from an examination of debates about policing in the 1950s. Prevailing trends in law and order politics (eg, that populist politics supports additional powers) can be seen to be anchored in the contemporary political context rather than being timeless truths. The multiple roles of law, in governing relationships between state agencies and actors, not just between police and suspects, are also highlighted.

The use of community consultation to address socio-environmental degradation is entwined with contested democratic principles polarising views of its role. I frame this problem by examining three democratic paradigms faced with two contemporary problems. The deliberative argument that preferences require enrichment with debate mediates between the liberal-aggregative view that preferences are individual, private and amenable to aggregation and the view that participation in public life is foundational. Viewing consultation as deliberative reconciles the liberal-aggregative view of consultation as the illegitimate elevation of unrepresentative minority groups with the participationist view that consultation constitutes a step towards participatory democracy. Theorists of social reflexivity, however, point to an elided politics of knowledge challenging technoscience's exemption from politically garnered consent. Also neglected by much democratic theory is how functional differentiation renders self-referential legal, political, technoscientific and administrative domains increasingly unaccountable. I employ Habermas' procedural theory that public spheres allow social irritations into the political domain where they can be encoded into laws capable of systemic interjection in response, along with a dialogic extension accommodating the politics of knowledge. I then use this procedural-dialogic deliberative understanding of democracy to elucidate the context and outcomes of the NSW State's consultative strategy. The NSW state, institutionally compelled to underwrite economic growth, implicating itself in that growth's socio-environmental side effects provoking widespread contestation. The resulting Environmental Planning and Assessment Act (1979) and its adjunctive consultative provisions helped highlight the socio-environmental degradation of the Hawkesbury Nepean River Catchment via Western Sydney's urban sprawl, politicising the region. The convenement of a consultative forum to oversee a contaminated site audit within the region facilitated incisive lay critique of the technoscientific underpinnings of administrative underwriting of socio-environmental degradation. The discomforted NSW State tightened environmental policy, gutted the EP&A Act's consultative provisions and removed regional dialogic forums and institutions. I conclude that the socio-economic accord equating economic growth with social progress is both entrenched and besieged, destabilising the political/administrative/technoscientific regime built upon it. This withdrawal of avenues for critique risks deeper estrangement between reflexive society and the NSW State generative of electoral volatility.

Dryland salinity occurs extensively throughout the Spicers Creek Catchment in central west New South Wales, Australia. The extent of dryland salinity in the Spicers Creek Catchment has severely altered the landscape, having major environmental implication. Large area of the catchments has experienced soil erosion resulting from the saline groundwater in the surface soil causing the destruction of clay and soil structure. The objective of this study was to use seismic refraction methods to map in detail a shear zone, which was associated with an area of major dryland salination. In particular, both the width of shear zone and the rock fabric within it were to be mapped with two both compressional (P) and shear (S) waves using a three-dimensional (3D) array of three- component (3C) receivers. The seismic data was recorded across a shear zone which is associated with salination in the Spicers Creek Catchment using the Australian National Seismic Imaging Resources (ANSIR) 360-trace system. Three-component (3C) geophones were used to record shear waves as well as compressional wave. An IVI minivibrator T-15000 was used as the main source of energy for the seismic survey. The results of the three-dimensional three-component seismic refraction surveys at the Spicers Creek Catchment show that the shear zone exhibit the seismic geophysical anomaly of a shear zone, existing as a narrow region with low seismic velocities and increased depth of weathering. A detailed analysis of the refractor seismic velocities and amplitude show a number of linear features parallel to and cross-cutting the shear zone. Linear features cut the shear zones at each site. They have been interpreted as a series of recent faults which act as discharge zone bringing saline groundwater to the surface.

The story of transport and accessibility problems in rural Australia is very similar to other wealthy countries with low rural densities and long distances such as the US and Canada ??? little or no public transport, very high levels of car ownership, and poor service provision. During the past two decades rationalisation and privatisation of services has led to the closure of many basic services in rural Australia. The withdrawal of services has necessitated longer distance travel for many rural residents ??? a problem which has been exacerbated by the rationalisation of public transport services. As a result there have emerged severe accessibility and mobility problems in rural areas, despite the presence of high levels of car ownership in such areas. In terms of rural transportation, the situation in Australia is characterised by two different features; first, poor public transport provision (or non-existence). Second; high levels of car ownership among rural residents. However, high levels of car ownership do not reflect high levels of prosperity; this is likely to indicate a situation of &quotenforced ownership&quot in response to declining levels of public transport provision. Furthermore, many rural residents neither own a car nor have access to a reliable public transport system due to socio-economic and location-based circumstances. Previous research has shown that these residents generally belong to groups who include the elderly, teenagers, students, Indigenous residents, unemployed persons and low-income households. Such groups have been termed transport-disadvantaged. The contention of this thesis, however, is that such groups are in a state of &quottransport need&quot given their range of transport related problems. This is one dimension of the accessibility problem in rural Australia, which has yet to be investigated. This thesis is concerned with the measurement of transport need through the development of several transport need indices using available census data. The key objective of this thesis is to investigate the relevance and suitability of need indices for identifying the relative spatial distribution of transport needs in rural areas. Geographical Information Systems (GIS) is used for the development, analysis and visualisation of the transport need index. This thesis examines transportation needs in rural NSW simply by measuring &quotdemand&quot and &quotsupply&quot components of transport. To measure the demand index, some socio-economic characteristics of population are involved including: the elderly, no or low car owning households, Indigenous people, students, children, unemployed persons, low-income households, and accessibility. A weight has been assigned to each component based on its relative importance among the other components. Weighted values are then standardised based on 100. To measure the supply index, six components, which represent the availability of various kinds of transport in rural NSW are involved and have been calculated by assigning weights and standardising to 100. These are: CountryLink rail services, CountryLink coach and bus services, Regional Services, Community Transport Program, Wheelchair taxi services, and School Buses. The final transport need for rural NSW is calculated by dividing demand index by supply index. It simply quantifies transportation needs across the rural Statistical Local Areas (SLAs) of NSW. In addition, this thesis discusses the potential and limitations of GIS and our transport need indices to be used as input to decisions about improvements in provision of services, and coordination of existing services to better meet identified needs, for the transport disadvantaged in rural NSW. In essence, this thesis is an attempt to make Australian transport and social services planners aware of the value of a need based transport-planning methodology.

This exegesis forms part of a cycle in the author's ongoing journey into the space of one tree, Eucalyptus gummifera. Many previously unchartered zones of experience give rise to experiences which are perceived slowly, with an open mind, in order to communicate an assemblage of experiences, objects and data which have come together to represent a reading of elements of the landscape of the Sydney Basin, one place where Eucalyptus gummifera grows. Each element has a niche within a specific grid of interaction that takes place in this lived environment. The work surveys fields of physical objects and relationships, inspiring new readings and translations of the landscape of one's own discoveries. Here the world acquires perspective and significance which enables fresh understandings and the deeper accquisition of knowledge. Thus the interactions in this sequence of the author's journeys into the space of one tree reveal further elements of the spatial landscape of Eucalyptus gummifera. / Master of Arts (Hons)(Contemporary Arts)

An investigation of the geological resources of the Southern Highlands was undertaken and over two hundred samples were collected and examined for possible use as stoneware ceramic ingredients. Thirty four of these samples were tested for possible use as clay body ingredients, while sixty five samples were selected for assessment as glaze ingredients. A wood fired kiln was built from firebricks produced from a local deposit of a white bauxite related material. Materials selected as a result of these tests were combined to create ceramic objects fired at stoneware temperatures. The most interesting result of the investigation was the discovery of a number of small weathered dykes and sills, samples from which were developed into workable ceramic clay bodies and glazes using a simple empirical testing procedure. A previously unknown excellent white translucent native porcelain stone or ‘bai tunze’ was discovered and developed into a workable porcelain body. Some iron stained porcelain bodies that ‘flashed’ red in the wood firing kiln were also developed. Exhibitions of the creative work produced were shown in the ‘Legge Gallery’, a Fine Art gallery in Sydney. Two critical reviews of those shows appeared in the magazine Craft Arts International, No. 64, 2005, pp 106-107 and The Journal of Australian Ceramics, Vol 46 #1 pp 21-24. Several papers were published detailing various aspects of the research: “The Search for Raw Materials in the Southern Highlands” in The Journal of Australian Ceramics, Vol 41#3, pp 22-23; “Flotation – A method of refining useful minerals”, in The Journal of Australian Ceramics, Vol 41#3, pp 24-25; “Magic Dirt” in The Journal of Australian Ceramics, Vol 46 #1 pp 76-79; “New work from an old landscape”, in Ceramics Technical, 24, 2007. pp 45-52;“From the ground up”, in Ceramic review, issue 222, 2006, pp 54-55. The research concludes that the Southern Highlands of New South Wales is geologically rich in suitable materials for the production of stoneware ceramics and that there are a few specific bai tunze like materials that are very interesting and have considerable aesthetic potential. The research determined that these bai tunze like materials are potentially capable of being developed into clay bodies and glazes of great beauty. / Doctor of Philosophy (PhD)

During the earliest days of the penal colony in New South Wales in 1788, the plight of the mentally ill was given little consideration by the governing authorities, particularly the convict insane, who lived (and died) by their wits and suffered cruel punishment if their behaviour was seen as recalcitrant. This thesis traces a history of mental health carers (nursing) from the foundation of the penal colony until the Federation of the Australian colonies to form a nation in 1901. The research makes a contribution to the profession of mental health nursing by providing an understanding of the origins and development of that profession in New South Wales. The thesis also examines ways in which the historic development of mental health nursing has influenced the work of mental health nurses and nursing in the present, and exposes recurrent dominant issues of the past which will, if they remain unaddressed, continue to influence that profession in the future. / Doctor of Philosophy (PhD)
