This thesis describes an inquiry taken into the nature and genesis of landscapes experienced imaginally. The inquiry proceeds by introspection, by art making, and by exploring related writings. The terms pre-conceptual and pre-imaginal are used to refer to an unknowable dimension from which the conceptual and the imaginal rise, and attempts are made to confirm the conceptual and the imaginal as expressions and effects of this dimension. The possibilities of a continual interplay between the imaginal and the pre-imaginal in the inner life of writers and artists are explored. / Master of Arts (Hons)

The focus of this study is the formation of 'community' in contemporary greenfield master planned estates.The project is cast against the historical backdrop of modern utopian place-making, and the idea that a particular permutation of urban design, infrastructure and social programs can produce an ideal of community: of connectivity, social support and social identity. A further ambition of contemporay urban design is the marketable idea of securing a physical and social space. The thesis comprises four parts. Part I presents the theoretical framework of the thesis, a task which incorporates a review of theoretical concepts and of the relevant literature. Part II discusses methodological issues, the research design and research process, before providing background information needed to support the following empirical chapters. Part III comprises these empirical chapters and sets about detailing and analysing data captured through the comparative case study of Harrington Park and Garden Gates. The final section of the thesis provides an interpretation of the empirical and research data. It draws conclusions as to the character of the Master Planned Community (MPC)and the dynamics which contribute to its contemporary character. It concludes by attempting a tentative theory of the MPC. / Doctor of Philosophy (PhD)

In this thesis, aspects of the reproductive biology of four Banksia species that display in various combinations all the life histories currently recognised in the genus were compared. Species like banksias, from fire prone regions of the world are typically characterised by life histories (traits and organs) that in reference to fire response allow them to be classified as seeders or sprouters. Plants killed by fire and that rely on seed for regeneration are called seeders and those that have the capacity to survive fire and produce vegetative sprouts are called sprouters. The species are Banksia ericifolia, Banksia integrifolia, Banksia oblongifolia, and Banksia serrata. The study was conducted in the Sydney region of Australia, which was arbitrarily divided into North, Central, and Southern provinces for sampling across species. It has been generally hypothesised that several traits are likely to be associated with seeders and sprouters. However, these traits were not always clearly apparent from the author’s studies. It is argued one reason for the anomalies in the expected associated traits is a result of a tendency to assume a evolutionary history that is based on fire as being the primary selection pressure. / Doctor of Philosophy (PhD)

This thesis is the first substantive analysis of unregistered proprietary horse racing (or pony racing, as it was popularly known) in Sydney, an extremely popular form of the sport conducted weekly or more frequently between 1888 and 1942. However, a number of researchers working on its periphery have contributed commentary and judgements to a discourse on it that has existed since the establishment of the Sydney Turf Club (STC) in 1943. Their writings have created an orthodox view of the sport that suggests inter alia it was a cultural expression of a ‘needy and greedy’ element of the working class and that its constituency was excluded from that of the racing of the Establishment, conducted by the Australian Jockey Club (AJC). This orthodoxy also holds unregistered racing was subject to endemic corruption, haphazardly conducted, inexpensive to attend, provided poor money and was in general a burlesque of AJC racing. The thesis engages this discourse and tests the tenets of the orthodoxy through examination or re-examination of relevant primary sources, including parliamentary papers, contemporary newspapers and journals, race books and other documents, administrative records, photographs, and the memoirs and transcripts of oral history provided by human participants. / Doctor of Philosophy (PhD)

Doctor of Philosophy (PhD) / Over 85% of Australia’s population live in urban areas and many turtle populations occur on Australia’s east coast where urban development is particularly concentrated. In the state of NSW, over half of the freshwater coastal wetlands have been highly modified or completely destroyed, and urban freshwater creeks often have only a narrow strip of weedy bushland left along their banks. Even though habitat degradation may result in declines in density and distribution of turtle populations, there are few data on Australian freshwater turtles in urban areas. In addition to extreme habitat alteration, urban waterways are innundated with anthropogenic contaminants from sources including wet weather surface runoff and industrial and sewage discharges. Pollutants can impact all systems of the body with potentially severe effects on reproduction and survival that can result in deterioration of animal populations. Turtles are particularly susceptible to anthropogenic contaminants due to their intimate contact with the aquatic environment, an often high trophic level, their ability to accumulate toxins, and their longevity. For almost all contaminants, the degree of accumulation in and effect on reptile species is unknown. Sublethal effects in field situations are particularly poorly studied and have never been documented in pleurodiran turtles. As a pioneering work in Australian reptile ecotoxicology, this thesis takes a broad approach, but focuses primarily on immunotoxicity and reproductive toxicity – two areas that greatly impact the size and continuance of animal populations. The aim of the thesis is to provide baseline data on haematology, cellular immunology and tissue metal concentrations for freshwater turtles in Sydney – data which were lacking for all Australian turtle species prior to this study. After initial assessment of the distribution and density of freshwater turtles in Sydney, the study examines the potential for Sydney’s turtles as sentinel species for measuring the effects of pollution on haematology, cellular immunity, and parasite loads; and considers the relationships between urban metal pollution and reproductive variables. The relative suitability of non-lethally sampled tissues (blood, carapace, egg) for use in biomonitoring is also assessed. Three species of Australian freshwater turtles were found in the Sydney region, with Chelodina longicollis occurring naturally in the area, and populations of Emydura macquarii and Elseya latisternum likely to have originated from translocated individuals. The North American turtle Trachemys scripta elegans was not encountered during this study despite concerns that it was establishing in the Sydney area. Chelodina longicollis populations were widespread, although poor recruitmment was indicated by low capture rates and comparatively low percentage of juveniles at some sites. Not so widespread, Emydura macquarii was present in much larger numbers than C. longicollis and with a high juvenile component in some areas of southeastern Sydney. I provide information on erythrocyte and leucocyte parameters in C. longicollis over a range of sites, pollution conditions, and seasons. In C. longicollis, numbers of lymphocytes, heterophils and eosinophils varied over sites, but not due to pollution from sewage treatment plant outfalls. There was significant temporal variation in erythrocyte, lymphocyte, eosinophil, heterophil, and basophil number, the heterophil:lymphocyte ratio, and haematocrit, but not consistently among sites. Future studies should ensure simultaneous sampling across sites for comparative purposes. Similarly, turtle populations downstream of sewage treatment plant outfalls showed no consistent difference in number, body condition, blood haemogregarine load, or leech (haemogregarine vector) load from upstream populations. Leech (Helobdella papillornata, with some Placobdella sp.) load and haemogregarine numbers increase dramatically once C. longicollis reach a carapace of 110 mm. The number of leeches on turtles varied across season, year, and site. Turtles with large numbers of leeches had reduced haematocrit, but the presence of leeches had no other correlations with haematological parameters. Haemogregarine numbers did not change across season or year, and were not correlated with haematological variables. The hypothesis that pollutants lead to an increase in normal blood protozoa due to reduced immunity thus was not supported. The concentration of metals in C. longicollis and E. macquarii carapace and in lagoon sediments varied significantly over four urban and four national park sites, but not based on this split. Pollution in periurban areas, such as illegal dumping of toxic wastes and atmospheric deposition of pollutants, means that each site must be classified separately as to degree of metal pollution. There was little or no affect of species, size, sex, or gravidity on metal concentrations in the carapace of adult turtles. Emydura macquarii had higher concentrations of blood Fe than C. longicollis from a different site, but this is possibly due to an increase in haemoglobin resulting from the site’s low aquatic oxygen concentration rather than any increased environmental exposure. Chelid turtles in Sydney do not show much promise as a biomonitoring tool. Carapace analysis is largely discounted as a potential tool for metal biomonitoring due to poor correlations between potentially toxic metals in non-lethally samplable tissues (carapace, claw) and internal organs (liver, kidney) or bone (femur). However, carapace metal concentrations still potentially reflect long-term metal presence or different dietary exposures as evidenced by the significant variation in concentrations over sites. A rare correlation was found for concentrations of aquatic Pb and carapace Pb, and a correlation was also found for concentrations of blood Pb and carapace Pb in E. macquarii. Thus any potential for tissue biomonitoring seems to lie with this highly ecotoxicologically relevant metal. Although two other ecotoxicologically relevent metals, Cu and Se, were significantly higher in egg contents of C. longicollis compared to E. macquarii, these elements are also essential and a lack of baseline values means it is not known if this simply reflects natural taxonomic variation. Ni, a metal of toxicological concern in sea turtles, was not present in egg contents, and only variably present in eggshell. The absence of Pb from eggs, despite its presence in many maternal tissues, suggests that selective metal uptake into eggs may be protective of toxic elements, rather than eggs serving as a maternal method of toxic metal elimination as has been previously suggested. The paucity of toxic metal detection in eggs renders them unlikely tissues for biomonitoring. The maternal tissue or tissues or environmental source from which egg metals originate remains obscure, although a significant negative effect of maternal carapace concentrations of Ca and Mg on eggshell thickness in E. macquarii indicates that there may be mobilisation of Ca and Mg from the carapace for eggshell formation. The only metal whose eggshell concentration correlated with eggshell thickness was Mg, indicating that ecotoxic metals previously associated with eggshell thinning are not problematic in the Sydney chelids. As with North American turtles living at polluted sites, none of the chelid hatchlings were found to have any overt abnormalities. Hatching success was poor and hatching mass low for eggs of both C. longicollis and E. macquarii, although results from natural nests are required to determine whether or not this was an outcome of hormonally-induced oviposition and artificial incubation. It is difficult to interpret metal concentrations found in the soft tissues, calcified tissues, and eggs of chelonians due to the paucity of comparative data, and much more research is required on tissue metal concentrations before patterns will emerge. This especially applies to pleurodires for which no previous information is available. From comparisons with the limited data available for other freshwater turtles, marine turtles, and other aquatic reptiles, it does not appear that Sydney’s turtle populations have unusually high metal concentrations in tissues. Exclusion of toxic metals such as Pb from the egg may also be protective to the developing embryo. An ability to live in polluted habitats, while limiting the accumulation of toxic contaminants, may be one key to their persistence in urban waterways from which other freshwater fauna have disappeared. Reproductive impacts such as low embryo survival and small hatchling weights require more rigorous examination, but may have less effect on these animals which have such naturally high egg and hatchling mortality. Although it was generally hard to demonstrate biochemical, physiological or population impacts of contaminants, C. longicollis from a site with severe sewage pollution did display unusual alterations in a number of haematological variables, body condition, and carapace bone structure. Despite this, the population was large and had a comparatively high ratio of juveniles. Additionally, the adverse haematological alterations appeared reversible. Thus, successful populations in Sydney probably are more dependent on basic ecological needs being met, than on low levels of environmental contaminants. The ongoing persistence of chelid populations in Sydney is likely to be dependent to some extent on their opportunistic diets, which generally make animals less vulnerable to habitat modification and the reduction in prey item diversity following pollution (Mason 1996, Allanson & Georges 1999), with a further benefit possibly bestowed at some sites on E. macquarii by its omnivory.

There has been a continuous decline in both the production and general performance of the SRO in NSW estuaries over the past three decades. The relationship of this decline to both environmental and oyster-density related factors are assessed in this thesis. This question has been examined at different scales: a large scale that compares two different estuaries (Clyde and Shoalhaven Rivers, southern NSW); a regional scale that encompasses variations within an estuary and, at a lease scale that examines processes pertaining to individual or small groups of oysters. Levels of inorganic nutrients were in general very low potentially limiting primary production. The limiting nutrient was nitrogen or phosphorus depending on whether long term conditions were dry or wet, respectively. Only during rain events, through the input of terrestrial material, were conditions favourable for fast rates of primary production. Carbon and nitrogen isotope analysis has demonstrated that both external material and local resuspension of the benthos constitute a major proportion of the SRO diet. The uptake of the various food sources also varied considerably depending on local environmental conditions. Increases in SRO growth were strongly correlated to increases in temperature with a low temperature cut-off at ~13°C. Growth also appeared to reduce considerably when salinities lower than ~15ppt persisted for the order of a month. These factors may alter growth through changes in filtration rates. These processes were modelled in a coupled hydrodynamic-NPO (Nitrogen-Phytoplankton-Oyster) model of the Clyde River. This demonstrated that primary production was more affected by estuarine dynamics and nutrient concentrations than oyster uptake. At the current levels of oyster densities, primary production by itself could not account for the observed oyster growth, however growth became realistic with observed levels of POC added to the model. A set of environmental indices were used to complement the model and to assess the sustainability of the culture system. The combined indices indicated that while the ecological carrying capacity of the Clyde was exceeded the production capacity at an estuarine scale was not. On the lease scale, density experiments showed that while growth was not reduced as a result of current stocking densities, the condition index was significantly affected.

Agricultural shows are community-based festivals that represent a majority of festivals staged in rural destinations within Australia. Recent anecdotal evidence indicates their survival is being threatened. Declines in the overall number of shows and visitor attendance have been widely reported, yet an analysis of the reason for these declines has not been investigated. Agricultural shows are managed by volunteers within not-for-profit show societies who are finding it difficult to survive in an increasingly competitive and challenging external environment. Little is understood about these show societies, their volunteer managers and the management effectiveness. This study has addressed these gaps by investigating show society management effectiveness by means of a marketing concept paradigm. A case study method employing qualitative in-depth interviews with key show society members and other stakeholders was conducted on one agricultural show. Findings reveal that this show society is managed by volunteers whose primary involvement motivation is based upon self-interest in one or more components of the show. The majority of these individuals do not have management skills and expertise required to manage a festival and whilst it is important to note their volunteering contribution, it is this lack of skills and knowledge that has prevented a systematic approach to management. There is no attempt at consumer research, strategic planning, organisational planning or volunteer recruitment. The show programs do not change to reflect the current needs of the community, rather what is affordable, who can organise it and what has always been done. As a result, the case study show society is not employing a marketing concept orientation but a product concept orientation. This study concludes that without this focus, the show society will be ill equipped to meet changing customer demands and stay abreast of competitors. To assist agricultural shows to manage future challenges and adopt a marketing concept, a theoretical model has been proposed that incorporates existing frameworks and this study’s findings. / M.

This thesis seeks to examine the nineteenth-century art collections and architectural style of the original buildings at the University of Sydney in order to demonstrate ways in which visual material may be employed to shape public perception of an institution. I shall argue that the architectural style of the original university buildings was specifically chosen with particular aims which extended beyond the mere establishment of a tertiary institution for the colony. I will also argue that the style shaped the character of the institution, contributed to the maintenance of law and order in the colony, linked the colony more firmly than hitherto to the mother country and provided social benefits for the founders of the institution. The instant history and character thus imposed upon the institution was reinforced by the assembly of a portrait collection in emulation of other collections of portraits at leading institutions of the colony and the mother country, including the Oxbridge universities. Once the building proclaimed that the institution was comparable with the great universities of the world, the subjects of the portraits at the university could be placed in the class of founders of a great historical institution, thus at the same time enhancing the reputation of the institution and the individuals. The construction of an indentity through visual images was extended by the benefactions of Sir Charles Nicholson, the principal donor of works of art to the university in the nineteenth century. I argue that his intentions in relation to his collections were didactic but were also concerned with the entrenchment of the imperial hegemony over the colony, and again with the enhancement of his personal repuatation. This analysis shows how, by a complex of personal ambition and aspiration for the colony, the style of the buildings and the art collections formed were used to establish the colony as civilized and the new university as a bastion of English tradition.

This study explores the early history of Sydney's Rocks area at two levels. First, it provides a much-needed history of the city's earliest, oldest-surviving and best-known precinct, one which allows an investigation of popular beliefs about the Rocks' convict origins, and which challenges and qualifies its reputation for lowlife, vice and squalor. Second, by examining fundamental aspects of everyday life - townscape, community and commonality, family life and work, human interaction and rites of passage - this study throws new light on the origins of Sydney from the perspective of the convict and ex-convict majority. Despite longstanding historical interest in Sydney's beginnings, the cultural identity, values, habits, beliefs of the convicts and ex-convicts remained largely hidden. The examination of such aspects reveals another Sydney altogether from that presented by governors, artists and mapmakers. Instead of an orderly oupost of empire, a gaol-town, or a 'gulag', the Sydney the Rocks represents was built and occupied largely according to the tastes, priorities and inclination of the people, with relatively little official regulation or interference. While the Rocks appeared 'disorderly' in the eyes of the elite, it nevertheless functioned according to cultural rules, those of the lower orders - the artisans, shopkeepers, publicans, labouring people, the majority of whom were convicts and ex-convicts.

The aim of this research is to understand the socio-economic development of a metropolitan region in Sydney through an analysis of regional innovative activity. South West Sydney, a major growth region within Sydney, includes the Local Government Areas (LGAs) of Liverpool, Campbelltown, Camden and Wollondilly. This region has absorbed 25% of Sydney’s population growth in the period from 1991-2001. Although South West Sydney has experienced rapid population growth, this has not been matched by associated employment growth. In some sectors such as business services employment growth has been minimal in the previous decade, this is particularly the case in Liverpool, the regional centre of South West Sydney. Population growth is estimated to continue at the current rate (in excess of 5% per annum) for at least the next fifteen years. In this environment, local government authorities in the region are seeking ways in which to develop the regional economy of South West Sydney and increase the amount of sustainable employment commensurably with current population and labour force increases. The role of innovative activity has a central place in economic development. This thesis uses a ‘systems of innovation’ (SI) approach to examine innovative activity in the South West Sydney region. SI understands innovation as a socially embedded process of transforming ideas and knowledge into novel products, processes and services through the processes of learning and searching. The approach recognises that innovative activity is determined by various actors (firms and institutions) and the interactivity between these actors and the cumulative base of knowledge in which they operate. The Regional Innovations Systems (RIS) framework develops from an acknowledgement that innovation is primarily a geographically bounded phenomenon. The RIS approach sees that specific local resources are important in determining and encouraging the innovative activities carried out by local firms and hence, the competitiveness of these areas. The RIS literature provides two fields of understanding of what constitutes a regional innovation system. The first takes the global examples of highly innovative regions such as Silicon Valley and Route 128 in the United States of America (Saxenian 1994), South West England (Cooke and Morgan 1998), Baden Wurttemberg in Germany (Cooke 2001; Braczyk, Cooke et al. 2004), Northern Italy (Piore and Sabel 1984) and in Australia, the North Ryde corridor (Searle and Pritchard 2005). These regions represent ‘ideal’ or ‘star’ RIS, with highly specialised and networked clusters of firms, many forms of supporting regional infrastructure, and high levels of interactivity. The second and emerging field understands RIS to be in existence in all regions and individual RIS are identified on a scale from weak to strong (Wiig and Wood 1995; Cooke and Morgan 1998; Cooke 2001). This second stream includes the analysis of regions seeking to encourage innovative activity by using the RIS approach to examine their local resources and connectedness. It seeks to determine how not only local resources but also their connectedness could be enhanced to increase firm competitiveness. The innovation systems represented in the ����ideal���� regions are largely a world away from what is available and what is necessary in the encouragement of RIS in most other regions. However, the conceptual framework for examining and interpreting RIS is derived from the analysis of these ‘ideal’ regions. This framework does not provide for measurement and effective interpretation of a range of activities that may be present in less exceptional regions. This research contributes to this endeavour by providing a method that allows for interpretation of a wider range of innovation activities through the analysis of knowledge intensive services activities (KISA). The focus on knowledge gathering, particularly through the KISA analysis, provides an examination of the relationship between innovation, learning and knowledge, much more so than more traditional measures of innovative activity e.g. patents and research and development (RandD) expenditure. KISA analysis is an emerging field of innovation research. KISA are closely linked to firm innovative activity (OECD 2006) and through an analysis of regional KISA usage, an understanding of innovation and knowledge activities within the region can be constructed. This analysis applies equally across various regions and provides an opportunity to guide regional economic development policy intervention at the local government level in South West Sydney. / Doctor of Philosophy (PhD)
