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.

In present day society there is an artificial dichotomy between wastes and resources that is perhaps best summed up by the Western Sydney Waste Board slogan 'there is no such thing as waste � only resources in the wrong place and at the wrong time'. Waste management was originally driven by managing the health consequences of wrong time/place materials. This has changed and the significant driver is now the sustainable utilisation of resources, that is, trying to optimally recover as resources (right time/place) those materials that present as wastes requiring management. However, it is not acceptable to justify a resource recovery option purely on the basis that it is diverting material away from landfill. Preferences are emerging for recovery activities that maximise the resource value of a material according to techno-economic, environmental and socio-political criteria; collectively known as the criteria of sustainability. The people and organisations articulating these preferences include owners/operators of resource recovery centres, proponents of alternative waste management technologies, waste planners and managers at both a state and local government level and environmental NGOs representing community interests, in addition to the generators of waste at a domestic, commercial and industrial, and construction and demolition level. It is therefore important to be able to answer the question of 'what is the optimal or most sustainable resource recovery option for materials presenting as waste to landfill in the Greater Sydney Region?' The point of departure for this thesis is twofold. Firstly, that optimal resource recovery options (also known as alternative waste management technologies) can be identified by understanding the context and system drivers and constraints within the system of waste generation and utilisation, by modelling the system using industrial ecology (specifically Materials Flux Analysis) and by using the technology assessment framework developed by the NSW Alternative Waste Management Technologies and Practices Inquiry to evaluate the available options. Secondly, that should the assessment framework from the NSW Inquiry prove to be unsuitable as a framework for evaluation, then an improved and refined assessment framework can be constructed in order to identify optimal resource recovery options and that this process can be successfully demonstrated using wood waste as a case study. The context of waste as an issue has shifted from local government control (pre-1970s) to state government control through the Department of Environment and Conservation. This transition followed experiments with organisations such as the NSW Waste Boards and Resource NSW, in addition to state targets such as a 60% reduction of waste to landfill by the year 2000. In addition to this backdrop of change from a government administrative perspective, there are also a suite of often conflicting drivers and constraints influencing the process of resource recovery. For example, sustainable development is a public policy driver for the integration of environmental and societal concerns, but can also constrain new innovation if competing 'status quo' utilisation options are not subject to the same scrutiny. Similarly, legislation acts as a constraint to resource recovery options by establishing license conditions, prohibiting some energy recovery options and setting recovery criteria; however legislation also acts as a driver for resource recovery options that generate renewable electricity or act to reduce greenhouse gas emissions. Other drivers and constraints include social, technical and economic issues and concerns in addition to environmental impacts such as emissions to air, land and water. Industrial ecology is a model for viewing system components as part of a dependent and interrelated greater whole. Within the context of Industrial Ecology, waste is a by-product of manufacture available as a beneficial input into other processes. Using Materials Flux Analysis as a tool to build a model of waste generation and utilisation, elements within the system are presented as a series of stocks (sources), technology interventions (transformation flows) and sinks (markets). The stocks or sources of materials for resource recovery are categorised as Municipal Solid (MSW), Commercial and Industrial (C&I) or Construction and Demolition (C&D) wastes. Approximately seven million tonnes of waste is generated in the Greater Sydney Region (nearly two and a half million tonnes of materials recovered for recycling and four and a half million tonnes of materials disposed of to landfill). The purpose of technology intervention is to transform the material into a product that is suited to the end market (sink). Markets are grouped according to reuse (same function and form), direct recycling (same supply chain), indirect recycling (different supply chain) and energy recovery (either as process heat, electricity or co-generation, a combination of the two). Landfill is also a potential sink for materials and in this sense can be thought of as a negative value market. The Alternative Waste Management Technologies and Practices Inquiry provided an assessment framework for resource recovery technologies. Each technology was measured and compared against 16 evaluation criteria, resulting in a score out of one hundred. Material sorting scored the highest (81.5), incineration the lowest (50.8) with most of the biological technologies performing �well� (64.6 � 71.7) and with the landfill technologies performing 'moderately well' (60.4 - 61.4). The positive features of the Inquiry included the overview of alternative resource recovery technologies, waste generation and other issues pertinent to decision making and resource recovery. The negatives of the Inquiry arise from the inadequacies of the assessment framework, which lacked technology options, system boundary definition and requisite evaluation criteria in addition to inconsistencies in scoring approaches. By undertaking a sensitivity analysis on the Inquiry�s results, it is shown that rank order reversal results from the allocation of weightings. The improved and refined assessment framework, constructed to overcome identified inadequacies of the Inquiry�s approach, focussed on clearly identifying the problem to be addressed and the primary decision maker involved in the process; ensuring that appropriate options for evaluation were included; defining the system boundary for the assessment; selecting necessary evaluation criteria; adopting a more sophisticated system for scoring; and using a sensitivity analysis to validate the results of the resource recovery option evaluation. Wood waste was used as a case study for this second assessment methodology. Wood waste refers to the end-of-life products, failed products, offcuts, shavings and sawdust from all timber products. Approximately 350,000 tonnes of wood waste are disposed of to landfill each year. This comprises untreated timber (hard wood and soft wood), engineered timber products (particleboard, medium density fibreboard and plywood) and treated timber (predominately copper chrome arsenic). Eight wood resource recovery options are selected for evaluation within the Greater Sydney Region with a different approach to scoring that has the advantage of 'scaling up' the best performers within each attribute (highest score) while 'scaling down' the worst performers (no score). Under this evaluation, an on-site purpose built energy facility is the most preferred option with particleboard manufacture the least preferred option. A sensitivity analysis of the results reveals that the scores of each technology option are sensitive to the weightings of the decision maker. When the change in rankings is examined, it is identified that two eight wood recovery options undergo a large rank reversal. A critique of the results of the wood evaluation reveals five major flaws. Firstly the evaluation produces non-highest resource value results that are non-intuitive (and arguably misleading), for example the poor performance of reuse and particleboard against energy generation options. Secondly, the recording of a single summary score for each recovery option hides unacceptable performance levels in some criteria. For example, the top scorer of Primary Energy On-site hides the fact that such an option is likely to have no political desirability (likely public opposition to 'incineration' within the Sydney air-shed), calling into question its ability to be implemented as a solution. Thirdly there is a reliance on judgement for the scoring of options and weighting of preferences, calling into doubt the accuracy of scores. Fourthly, the rankings of recovery options by the assessment framework are sensitive to the allocation of weightings. Finally and most importantly, the refined evaluation approach suffers from the 'discrete option syndrome', the scoring of each recovery option in isolation with no ability to look at integrated systems with joint recovery options. This is pinpointed as a fundamental flaw in the process of both the Inquiry and the wood evaluation. This leads to the conclusion that the founding assertions of this thesis were false. That is to say that the assessment framework developed by the NSW Alternative Waste Management Technologies and Practices Inquiry is not suitable for use in evaluating resource recovery options. Furthermore a refined assessment framework based on this approach is also unable to identify optimal resource recovery options as demonstrated using wood waste as a case study. The results of this research points to the overall conclusion that any discrete option evaluation and assessment for resource recovery technologies that results in a single summary score for each option will be fundamentally flawed, providing no value in determining optimal resource recovery solutions for the Greater Sydney Region. A systems approach is suggested as an alternative method for the evaluation of optimal resource recovery, the starting point of which is to ask 'what is the highest resource value of the components in the material stream under consideration and how could a network of infrastructure be designed in order to allow materials to flow to their highest resource value use?' A feature of such an integrated approach is a focus on the materials composition of recovered resources, as opposed to recovery technologies, resulting in a 'fit for purpose' as opposed to a 'forced fit' style of resource recovery. It is recommended that further research and public policy efforts be made in logistics planning across the Greater Sydney Region (as opposed to a regional or local government area) in order to create network opportunities for integrated flows of materials to move toward their highest resource value.

The purpose of the present study is to examine the genetic and morphological variation found in narrow-range endemic terrestrial invertebrate species at different geographic scales, and the ramifications of this for their systematics, management and conservation. The listed endangered land snail Meridolum corneovirens and several related forms are restricted to the Sydney region, and were used to address the above issues. Morphological, anatomical, allozyme and DNA data were obtained for a total of 77 populations from across the known range of Meridolum. A particular emphasis was placed on the forms found across the Sydney region. The analysis of the different datasets, both individually and in combination indicate at least 35 taxa mostly parapatric and seven genera were represented. This includes several previously unrecognised taxa. The analysis supports the conclusion that Meridolum corneovirens belongs to a new genus. This includes several species found from eastern Sydney south along the coast to Nowra. A total of six new species and five new genera are described. The conservation and management of narrow-range endemics such as Meridolum corneovirens provide a number of challenges to conservation managers. The alternative of listing a gene pool rather than listing species separately is proposed and explore

Estuarine acidification, caused by disturbance of acid sulfate soils (ASS), is a recurrent problem in eastern Australia. Affected waters are characterised by low pH and elevated concentrations of metals, principally aluminium and iron. The effects of acid and elevated metal concentrations associated with ASS, on adult Sydney rock oysters, have not been previously investigated. This study tested links between ASS-affected drainage, subsequent estuarine acidification and Sydney rock oyster production problems on the Hastings and Manning Rivers, mid north coast New South Wales. The primary objective of this thesis was to establish if estuarine acidification causes mortality and slow growth in individual Sydney rock oysters by exposing oysters to low pH, iron and aluminium using field and laboratory experiments. Water quality data showed that estuarine acidification was spatially extensive in the Hastings and Manning Rivers following heavy rainfall and was due to mineral acids originating from drained or excavated ASS. Estuarine acidification regularly affected areas used for Sydney rock oyster production following heavy rainfall. Field experiments showed that Sydney rock oyster mortality rates were significantly higher at sites exposed to ASS-affected waters compared to locations that were isolated from ASS-affected waters. Oyster mortality increased with the time of exposure and smaller oysters (mean weight = 5 g) experienced significantly higher mortality relative to larger oysters (mean weight = 29 g). This was caused by acid-induced shell degradation resulting in perforation of the smaller oysters??? under-developed shells. Additionally, Sydney rock oyster growth rates were dramatically reduced at sites exposed to ASS-affected waters and the overall mean condition index of oysters at ASS-affected field sites was significantly lower than the overall mean condition index of oysters at non-impacted sites. Findings from laboratory experiments showed that ASS-affected water alters oyster valve movements and significantly reduces oyster feeding rates at pH 5.5. Acidic treatments (pH 5.1) containing 7.64 mg L-1 of aluminium or ASS-affected water caused changes in the mantle and gill soft tissues following short-term exposure. Degenerative effects described in oysters in this study were also due to iron contained in ASS-affected waters. Iron precipitates accumulated on the shell, gills and mantle and were observed in the stomach, intestine, digestive tubules and rectum. This study concluded that Sydney rock oysters are unable to tolerate acidic conditions caused by ASS outflows and cannot be viably cultivated in acid-prone areas of the estuary.

The aim of the study was to characterise the environment in the Sydney region in respect of atmospheric corrosivity, timber decay risk factors and the corrosion of nails in timber in covered conditions. The study reviewed contemporary research in this field, particularly in Australia, developing an understanding of the durability failure mechanisms for timber and nails in timber. The study looked at the effects of climatic aspects, pollutants, corrosion on timber decay risk factors. The study found that the levels of risk in terms of timber degradation, corrosion and nail corrosion were greatest adjacent to the coast and at marine sites.

Over half of the world’s human population are living within an urban environment. As a result, urbanisation of the natural landscape has increased, involving extensive land use change, and reducing the ecological resilience of species living within these complex environments. Habitat fragmentation and isolation caused by urbanisation can reduce the landscape connectivity of the ecological network. Landscape connectivity between habitat patches is critical to sustain genetic diversity, migration and sufficient territories for many species within complex landscapes. Therefore to increase ecological resilience for species within an urban system increased effort is required on applying conservation measures to natural areas within an urban environment. The powerful owl (Ninox strenua) is one of many species affected by increasing urbanisation and land use change. It is the largest owl species in Australia and considered vulnerable within New South Wales. It is a habitat specialist that requires high density woody vegetation cover for both foraging (main prey being arboreal marsupials) and nesting, and has an extensive home-range. Though previous research has acknowledged the effect urbanisation will have on the owl, none have previously gone into its dispersal habitat requirements and the influence landscape connectivity will have on its dispersal and occurrence throughout an urbanised system. Hence this study has investigated the influence woody vegetation connectivity has on the dispersal and occurrence of the powerful owl within the Greater Sydney Region, NSW. The study is split into two main sections, 1) Mapping woody vegetation and 2) Analysing and evaluating landscape connectivity for the powerful owl. To generate a land cover map of the study area, high resolution aerial photographs and an object oriented analysis in combination with a classification tree was used. The land cover map produced for the study area achieved high overall classification accuracy (>85%) and for the woody vegetation class (>90%). To analyse landscape connectivity the circuit theory was used. The circuit theory takes into account all possible pathways the owl could potentially use for dispersal depending on the permeability and resistance of the landscape. Resistance layers were developed from the woody vegetation land cover map and other environmental or anthropogenic features which may facilitate or prevent dispersal. A novel approach to evaluate the connectivity surfaces with species distribution modelling was developed using presence data of powerful owl observations. Woody vegetation connectivity was determined to have a critical effect on dispersal between habitat patches for the powerful owl. Sensitivity to disturbance of its dispersal habitat was explored, with the results indicating high sensitivity to disturbance of its dispersal habitat. Therefore increasing land use change within the Sydney area will potentially decrease the available habitat for dispersal and reduce the powerful owl’s ecological resilience to future disturbance.

This interdisciplinary project offers new insights into the reclamation history of two of the most controversial and contaminated sites in Canadian history: the Sydney tar ponds and coke ovens and the Athabasca oil sands. It argues that Canada’s natural resource-dependent economy, combined with jurisdictional uncertainty, created a hesitant, fragmentary site cleanup regime, one that left room for different ideas about landscapes to shape and even distort reclamation’s goals and processes. In the absence of substantive reclamation standards and legislation, researchers struggled to accommodate the unique challenges of the oil sands during the 1960s and 1970s. Ambitious goals for reclamation faltered, and even the most successful examples of oil sands reclamation differed significantly from the pre-extraction environment; reclamation was not restoration. Planners envisioned transforming northeastern Alberta into a managed wilderness and recreation nirvana, but few of these plans were realised. The Sydney tar ponds experience suggests that truly successful reclamation cannot exist unless past injustices are fully acknowledged, reparations made, and a more complete narrative of contamination and reclamation constructed through open deliberation. Reclamation, after all, does not repair history; nor can it erase the past. Effective oil sands reclamation, then, requires a reconsideration of the site’s past and an acknowledgement of the perpetuated vulnerabilities and injustices wrought by development and reclamation.

Fire is a recurrent disturbance that removes above ground vegetation in many locations throughout the world, including the Sydney region. Many species in fire-prone locations, and most species in the Sydney region, form soil seedbanks and regenerate through post-fire germination. However, a germination response is determined by the fire regime acting as a selective pressure over a sufficient period of time, rather than a single fire. The components of the fire-regime are intensity, season, type and frequency. The natural fire regime is dominated by warm-season fire, but management burning is conducted in cooler seasons. Cool season burning produces lower levels of germination than warm season fires in a number of locations with Mediterranean-type climate, but the effects of cool season burning on species composition in the relatively aseasonal Sydney region is unknown. An experimental approach was adopted to address this lack of knowledge. Fire can be simulated using heat shock and smoke (fire cues), and the seasonal factors of temperature and water availability can be reproduced in the laboratory. I have investigated the effect of various combinations of heat shock and smoke, of various pre-and post-fire cue temperatures, of prefire cue hydration status, of various post-fire cue water availabilities, and of accelerated aging before application of fire cues on germination of a number of species forming soil seedbanks in the Sydney region. A degree of primary dormancy was overcome in most species by the combination of heat shock and smoke in the current investigation. Fire intensity is expected to influence germination, as germination of most species was increased by the combination of heat shock and smoke within a narrow heat shock range.The interaction between ambient temperature and the level of heat shock may affect germination. Soil water content, and thus seed moisture content at the time of a fire may interact with the level of heat shock to affect both germination and survival of a seed. The age of a seed may also affect its germination response to fire. The above factors are predicted to affect the germination of species differently, and thus season of fire is expected to alter species composition. Such predictions can be readily field-tested

This thesis examines community structure of cliff-top coastal heathlands in Botany Bay National Park, Sydney. Community properties of floristic composition, structure and species richness are investigated. This investigation is made in order to assess the justification for contemporary pre-emphasis in local studies on individual community properties. It is also made in order to assess the relative and independent contributions of individual properties to variance in overall community structure. It is also made in order to assess the relative utility of multi-property classifications in summarising community structure of cliff-top coastal heathlands. First, the presence of determinable structure in each property is assessed through multivariate classification of respective data sets. Secondly, a new model of community structure is developed in which the hypothesis that community structure is a function of common (shared) and independent (unique) variance in each of the three properties is assessed. This is achieved through application of variance partitioning using correspondence analysis techniques. Thirdly, a matrix combining variance in all three properties is classified. This classification is compared with those of individual properties in order to assess the hypothesis that more ecologically cohesive classifications than those of single properties are obtainable. The ecological significance (environmental relativity) of all classifications and variance components is assessed through examination of relationships with variance in 20 environmental factors which encompass variation in maritime factors, soil physical factors, soil nutrition factors and effects of time since fire. Classifications of individual properties showed the presence of determinable structure in each. Eleven floristic complexes, nine structural complexes and eighteen species richness complexes were recognised. Nineteen community complexes were recognised from the classification of the combined property matrix. All complexes were shown to differ significantly with respect to multiple environmental factors. Variance partitioning showed the presence of both independent and common variance components with respect to properties compared pairwise. These were all shown to differ in magnitude. Examination of environmental correlates showed ecological differentiation of all properties and most variance components. Maritime and fire factors provide a major axis of environmental differentiation for most properties and variance components. A second major axis was resolved with respect to physical soil factors. With the exception of variance in species richness, major soil nutrients were generally of secondary importance to community structure. Low soil nutrients may demarcate heathlands from other vegetation types. However, this study shows elevated importance of other major areas of environment for community structure within cliff-top coastal heathlands. Comparisons of environmental homogeneity characteristics between all classification systems showed the classification of the combined property matrix to be more ecologically robust than those of structure or species richness. Homogeneity characteristics of the combined classification remained statistically inseparable from that of floristic composition. However, studies provided some evidence suggesting greater robustness of the combined classification with regard to fine-scale variance in community structure. This thesis shows that variance in all major community properties of the studied vegetation to be of ecological significance. It also shows that this significance is differential with respect to properties and their variance components. Pre-emphasis on individual properties in syntheses of local systems thus involves the loss of ecological information. I thus conclude that if adequate ecological syntheses of cliff-top coastal heathlands are to be obtained which are appropriate to their scale of distribution and functioning in the Sydney area then inclusion of attributes of multiple properties is required. Equally, multiple sources of environmental variation need to be examined.

Urban sustainability is a desired future. The problem investigated in this thesis is how to achieve it, in the context of planning law which applies to residential development and infrastructure in Sydney. Two questions are addressed. First, what is urban planning for sustainability? Second, how can the legal impediments to urban planning for sustainability in Sydney be identified and overcome? The second of these is the research question considered by the thesis, which aims to make a valuable contribution to knowledge about the design of planning processes to facilitate the transition from the unsustainable city, to the sustainable city. The thesis commences with a discussion of the recent international urban sustainability literature. It is argued that planning focussed on protecting amenity or changing density (whether higher or lower), is insufficient for achieving urban planning for sustainability, which is defined as planning intended to reduce the ecological footprint and improve the liveability of the city. An original theoretical framework, comprising a set of eight criteria which form a sustainability planning process, is proposed as a checklist for identifying the legal impediments to sustainability. These criteria are termed Sustainability Planning Elements. The general discussion in the early chapters gives way to particular practical applications of the theory in the latter chapters. Legal research methods and analysis were used to investigate the presence or absence of the Sustainability Planning Elements in the planning laws which apply in Sydney. Any planning instrument, statute or court decision which does not contain the elements is identified as an impediment to sustainability. Conversely, where the elements are present, the law can be regarded as facilitating sustainability. The research findings contained m the thesis are intended to demonstrate how the impediments could be overcome by incorporating sustainability planning processes in planning law. The findings propose methods which include: • modifying the exercise of discretion in the consideration of development proposals; • imposing positive sustainability planning duties; • making planning decisions conditional on an application of the sustainability planning elements; • placing the onus on the proponent to satisfy the decision maker that development approval ought to be granted; • making sustainability a fundamental or primary planning objective.

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.

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.

The Douglas Summerland Collection is a fictional "monographically based history"1. In essence this research is concerned with the current debates about history recording, authenticity of the photograph, methods of history construction and how the audience digests new 'knowledge'. The narrative for this body of work is drawn from a small album of maritime photographs discovered in 2004 within the archives of the Port Chalmers Regional Maritime Museum in New Zealand. The album contains vernacular images of life onboard several sailing ships from the nineteenth and twentieth centuries, including the DH Sterling and the William Mitchell. Through investigating the'truth' systems promoted by the photograph within the presentations of histories this research draws a link between the development of colonialism and the perception of photography. It also deliberates on how 'truth' perception is still a major part of an audience's knowledge base. 1.
