It is widely believed that Australian Aboriginals utilised fire to manage various landscapes however to what extent this impacted on Australia???s ecosystems remains uncertain. The late Pleistocene/Holocene fire history from three sites within the Sydney Basin, Gooches Swamp, Lake Baraba and Kings Waterhole, were compared with archaeological and palaeoclimatic data using a novel method of quantifying macroscopic charcoal, which is presented in this study. The palynology and other palaeoecological proxies were also investigated at the three sites. The Gooches Swamp fire record appeared to be most influenced by climate and there was an abrupt increase in fire activity from the mid-Holocene perhaps associated with the onset of modern El Ni??o dominated conditions. The Kings Waterhole site also displayed an abrupt increase in charcoal at this time however there was a marked decrease in charcoal from ~3 ka. Lake Baraba similarly had displayed low levels of charcoal in the late Holocene. At both Kings Waterhole and Lake Baraba archaeological evidence suggests intensified human activity in the late Holocene during this period of lower and less variable charcoal. It is hence likely that at these sites Aboriginal people controlled fire activity in the late Holocene perhaps in response to the increased risk of large intense fires under an ENSO-dominated climate. The fire history of the Sydney Basin varies temporally and spatially and therefore it is not possible to make generalisations about pre-historic fire regimes. It is also not possible to use ideas about Aboriginal fire regimes or pre-historic activity as a management objective. The study demonstrates that increased fire activity is related to climatic variation and this is likely to be of significance under various enhanced Greenhouse scenarios. There were no major changes in the composition of the flora at all sites throughout late Pleistocene/Holocene although there were some changes in the relative abundance of different taxa. It is suggested that the Sydney Sandstone flora, which surrounds the sites, is relatively resistant to environmental changes. Casuarinaceae was present at Lake Baraba during the Last Glacial Maximum and therefore the site may have acted as a potential refugium for more mesic communities. There was a notable decline in Casuarinaceae during the Holocene at Lake Baraba and Kings Waterhole, a trend that has been found at a number of sites from southeastern Australia.

Since the great Iranian revolution of 1978-79, there has been a significant increase in Islamic consciousness and activity in Muslim communities across the globe. As a phenomenon it has become known as ???Islamic revivalism???. Its hallmark is a return to Islamic origins, the fundamentals of the faith embodied in the Qur???an and the sunnah (sayings and practices of Prophet Muhammad). Contemporary Islamic revivalism has its roots in Muslim responses to European colonialism and imperialism at the turn of the twentieth century, when the darker sides of modernity began to reveal themselves in what was perceived as less than desirable social, cultural, economic, and political conditions of many Muslim communities and societies. Islamic revivalism has constantly featured in Islamic history and is by no means a new phenomenon. What distinguishes contemporary Islamic revivalism from earlier revivalisms is its complex multifacetedness as a defensive reaction to a new epoch of modernity described in revivalist circles as jahiliyah (ignorance). This thesis argues there is a central relationship between modernity and Islamic revivalism. Using in-depth interviews and participant observation techniques this study is an ethnography of the Tablighi Jamaat (Preaching Party), a transnational Islamic revivalist movement active in Sydney. It also seeks to locate the Tablighi Jamaat in the spectrum of Australian Islam. The principal argument of the thesis is that contemporary Islamic revivalism is a defensive reaction to modernity. Contrary to popular belief it neither constitutes an antimodernity nor does it seek to destroy modernity. Rather, it highlights that Muslims as adherents to a revealed tradition - Islam - are in a serious state of crisis. They are confronted with both material crisis and the threat of losing their faith and identity in modernity. Through a study of the Tablighi Jamaat the thesis argues that contemporary Islamic revivalism is, therefore, an attempt to rescue Muslims from their modern malaise through selective use of modern ideological and technical means.

The research presented in this Thesis is primarily concerned with the field of Geographical Information Systems (GIS) - specifically, the business applications of the technology. The empirical problem addressed is the selection of branch banks as candidates for closure using the network of branch banks of the Commonwealth Bank of Australia in the Sydney metropolitan region as the case study. Decisions to close branches are made by the Bank on the basis of performance indicators that are essentially financial. In this research, however, an alternative approach is adopted: the problem is addressed using a set of spatial criteria. Following the deregulation of the finance industry in the 1980's and the rapid introduction of new electronic channels for delivering financial services, the major banking institutions have been engaged in a process of reorganising their networks of branch banks. The most visible manifestation of this has been the ongoing and widespread closure of branches. Selecting branch banks for closure is a typical example of a complex semi-structured multi-dimensional, multi-criteria, decision-making problem. It has been well documented in previous research that Multi-Criteria Decision-Making (MCDM) models are the most appropriate ones for solving problems in this particular domain. The identification of branches for closure is also characterised by a significant spatial dimension. Decisions are based on a consideration of a number of geographical criteria and various forms of spatial analysis may be involved. An appropriate technology to assist with solving decision-making problems with a significant spatial dimension is a Spatial Decision Support System (SDSS). Most SDSS have been based on the integration of Geographical Information Systems (GIS) technology with analytical models that are proven to be best suited to specific decision-making problems and this is the approach adopted in this research. The prototype MCBC-SDSS (Multi-Criteria Branch Closure SDSS) developed here is based on the integration through the loose coupling of the ArcView GIS software with the Criterium DecisionPlus (CDP) software, which contains the suite of non-spatial analytical models that provide the analytical capability for solving multi-criteria problems. ArcView GIS is used as the engine that drives the system and to provide the analytical and display facilities to support the spatial data involved. Two MCDM models from the CDP software are used to support the decision-making analysis - the Analytical Hierarchy Process (AHP) and Simple Multi-Attribute Rating Technique (SMART). The integration of GIS with the MCDM models is based on a considerable amount of software enhancement, interface development, and computer programming. The development of the integrated system is designed to create an intelligent and user-friendly SDSS, the application of which, from the user's perspective, is a seamless operation. The success of the MCBC-SDSS is demonstrated by its application to identify candidates for closure among the 197 branches of the CBA in the Sydney metropolitan area in 2000 - the year when the building of the database for the research had been completed. The analysis is based purely on spatial considerations that have been gleaned from a major review of the literature that previous researchers have identified as affecting branch viability and performance. A set of 17 spatial variables was used as the criteria in the MCDM models. The criteria are organised in two blocks: the first includes 9 criteria relating to the characteristics of demand for branch service in the branch trade areas ('catchment area' specific criteria) while the second includes 8 criteria relating to aspects of supply provided by the existing branches in their location ('location specific' criteria). Using the developed approach, the MCBC-SDSS has been used directly to compare alternatives against criteria, not only spatial based but also financial ones, thus providing a basis for identifying the best choices regarding branch closure. The steps in the preparation of the data and the iterative procedure for implementing the MCDM models are explained and illustrated. This involves building the initial evaluation matrix, normalising the raw criteria scores, assigning weights to the criteria, and calculating priorities. Based on these, the AHP and SMART models then calculate a decision score for each branch that is used as the basis for creating the preference ranking of the branches. In this, branches with a high rank score based on the combined weighted contribution of the 17 criteria are considered to be operationally viable. On the other hand, branches with the lowest rank scores are considered as potential candidates for closure. The preference rankings generated by the models have been tested to examine their robustness in terms of the validity of criteria and their weights used in the decision analysis. Sensitivity analysis has been conducted, the results of which show that the preference rankings are stable. Different approaches have been used to validate the initial criteria, and analyse their contribution to the ranking of branch banks for closure. These help identify critical spatial variables among the 17 initial criteria selected, and suggest that some of the criteria initially selected could be deleted from the criteria list used to generate the preference rankings without substantially affecting the results. The reasonableness of the resulting preference ranking has been further demonstrated from analyses based on changing criteria weights and alternatives. The research successfully demonstrates one of the ways of enhancing the functionality of a GIS through its integration with non-spatial analytical models to develop a SDSS to aid solving decision-making problems in the selected domain. Given that to date there has been relatively few applications of SDSS similar to that developed in this research to real world decision-making problems, the procedure adopted makes it suitable for decision-making in a range of other service business applications characterised by a significant spatial dimension and multiple outlets including shopping centres, motor car dealerships, restaurant and supermarket chains. Instead of just providing solutions, however, the SDSS-based analysis in this research can better be thought of as adding value to spatial data that forms an important source of information required by decision-makers, providing insight about the situation, uncertainty, objectives, and trade-offs involved in reaching decisions, and being capable of generating alternative scenarios based on different inputs to the models that may be used to identify recommended courses of action. It can lead to better and more effective decision-making in institutions involving multi-outlet retail and service businesses and hence enables both integrated data analysis and modelling while taking multiple criteria and decision-makers' preferences into consideration.

THE PROFESSIONAL LIFE-CYCLES AND PROFESSIONAL DEVELOPMENT OF ADULT TEACHERS OF ENGLISH TO SPEAKERS OF OTHER LANGUAGES (TESOL) This thesis focuses on the findings of a research study conducted in Geneva and Sydney to examine the career cycles of TESOLs. It explores many of the issues investigated in Huberman???s study of 160 secondary school teachers in Geneva (1989, 1993). Seventy-three in-depth interviews were conducted with teachers and trainers / administrators in adult TESOL, and professional development issues were examined in greater detail than in the Huberman study. The central purpose of the study was to test the universality of the Huberman model of career phases. TESOLs were found to have far more variations during their career cycles than school teachers, who were in a more stable and predictable situation. The study focused on particular moments in the career cycle, exploring TESOLs??? levels of satisfaction. TESOLs in the present study were found to have similar intrinsic satisfactions and concerns about working conditions as the findings of other TESOL studies. Although the occupation was reportedly becoming increasingly more professional, its unpredictable nature made it stimulating and rewarding. In spite of the instability of the TESOL career, TESOLs appeared to have more positive career experiences overall than many school teachers with more stable career paths. The study also examined professional development issues by comparing the perceptions of TESOLs and their trainers / administrators. They had many divergent opinions as to the professional development requirements of TESOLs. While there was no conclusive evidence that professional development could be linked to stages, TESOLs in a phase of diversification were found to have different professional development requirements from other phases. Personal, professional and environmental factors also affect the professional development requirements of TESOLs at any stage. In summary, it appears that the traditional career phase model is inappropriate when applied to TESOLs, and perhaps for other similarly unstable careers. With the recent changes in people???s professional lives, requiring increasing mobility and adaptability in the changing job market, other career path models to guide counselling, professional development and other staff management programs will need to be explored.

This thesis examines the theatricality which accompanied the establishment, development and deployment of the colonial army in New South Wales during the last two decades of the nineteenth century. It investigates the transfer to the colony of the military ethos of the Imperial power, and explores the ways in which performances of military spectacle, in both theatrical and paratheatrical contexts, were interpreted by the colonists. The primary sources for the research are the Sydney press and the Mitchell `Australiana' collection of the State Library of New South Wales. The framework of the argument is presented in five chapters. The first, Displaying, investigates the relationship between civilians and the military forces at training camps, and then the performances of sham fights. The second, Committing, explores the attitudes of civilians and soldiers at the departures of New South Wales troops to the Soudan and Boer Wars. Informing, thirdly, investigates how the Imperial military ideology was conveyed through performance, and how this information was interpreted in the colony. Accommodating analyses songs and theatre performances which first reflected colonial anticipations at the commitment to conflict and then attempted to accommodate the actuality of the experience. Lastly, Desiring, explores the colonists' endeavours to invent traditions which satisfied the discrepancy between their hopes and their experiences of Imperial war. This thesis asserts that the colonial reinterpretation of military ideology was influenced by concepts both of service to the Imperial power and of national identity. The interplay between these influences led to the colonists' idealising the Imperial association. This ideal was not demonstrated in the practice of association. The result of this experience was a defining of the differences between colonial and Imperial perceptions, rather than a reinforcement of their similarities. Much of the exploration of thesis also prepares the ground for a fuller cultural understanding of the issues at play in the final emergence of the Anzac tradition at the engagement of colonial soldiers against Turkish troops at Gallipoli in April, 1915.

Women architects are effectively absent from architectural history in Australia. Consulting first the archival record, this thesis establishes the presence of 230 women architects qualified and/or practising in NSW between 1900 and 1960. It then analyses some of these early women architects' achievements and difficulties in the profession, drawing on interviews with 70 practitioners or their friends and family. Finally it offers brief biographical accounts of eight leading early women architects, arguing that their achievements deserve more widespread historical attention in an adjusted canon of architectural merit. There are also 152 illustrations evidencing their design contributions. Thus the research draws on quantitative, qualitative, biographical and visual modes of representation in establishing a historical presence for these early women architects. The thesis forms part of the widespread political project of feminist historical recovery of women forebears, while also interrogating the ends and means of such historiography. The various threads describing women's absence and presence in the architectural profession are woven together throughout the thesis using three feminist approaches which sometimes harmonise and sometimes debate with each other. Described as "liberal feminism", "socialist feminism" and "postmodern feminism", they each put into play distinct patterns of questioning, method and interpretation, but all analyse historiography as a strategy for understanding society and effecting social change.

This thesis examines the social welfare work of four Catholic Sisterhoods in Sydney in the late nineteenth century. The work of Catholic women religious is largely missing from Australian women???s history and the history of social welfare and social work in Australia. The present investigation seeks to add to knowledge of women???s agency in Australian society and to extend the knowledge of Australian social work history. The aim of the thesis is to understand what the Sisters were attempting to do in their work with the poor of Sydney and how they went about it. The emphasis is on understanding the Sisters??? work from their own perspective, particularly the values which underpinned their work and the resources and constraints which affected it. A qualitative, inductive approach is used in which the data are drawn mainly from the Sisterhoods??? narratives and other historical documents. The thesis does not aim to test particular theoretical propositions, but rather to contribute to a number of ???unfolding stories??? about the history of Australian social work, about women???s work in the public realm, and about the development of the caring professions The thesis argues that the social welfare work of four Sydney Sisterhoods had a number of characteristics which made it unusual for the time, and which constituted it as ???proto-professional???. These included the codification of the prescribed stance towards the poor, of methods of work, and a high level of expertise in administration and management. The Sisters??? approach pre-figured later social work in a number of respects including an inclusive and accepting stance, respect for the dignity of the individual, and a concern to develop individuals??? capacities and self-esteem. The professionalism of the Sisters??? work is shown to be related to features which were integral to Catholic women???s religious institutes and to their role and status in the Catholic Church of the day. The Sisters??? social welfare work did not ???evolve??? into secular, professional social work however. It is contended that reasons for this were related to developments in Australian society, the situation of the local Catholic Church and restrictions on membership of the Sisterhoods. The thesis has significance for bodies of knowledge on ???woman???s sphere??? charity in the late nineteenth century, the history of social work in Australia, and theory on the professionalisation of caring occupations.

In the two decades between 1970 and 1990, hundreds of people passed through the ALP branches of Leichhardt Municipality. These were predominantly members of what this thesis calls a 'middle class Left', employed in professions and para-professions like teaching or the public service and motivated, to one degree or another, by the social movements and politics of the late 1960's and early 1970's. This is a social history incorporating the life histories of a selection of these people. It is set against the backdrop of conflicts with incumbent, conservative, working class-based political machines and the political climate of the times. The thesis is in four parts. Part I, the introduction, establishes the point of view of the writer as it shapes what is also a 'participant history'. In this context, and that of the oral history interviews, the introduction addresses the relationship between memory and history. Parts II and III are the body of the thesis and each is lead by a 'photo-essay', recognising the complimentary importance of a visual narrative. Part II sets out the broad political topography of the 1970's and early 1980's. Chapter one describes the middle-classing of the ALP in Leichhardt Municipality, set against a review of the principal literature. It then moves through chapters two to four to examine the three loci of middle-classing: Annandale, Balmain and Glebe. Part III moves on into the 1980's when the middle class Left 'takes power'. It examines, in chapter five, the emerging, sharp, divisions among the Left on Leichhardt Council and in the contests for federal and state parliamentary seats. Chapter six examines the deepening of these divisions in the mid to late 1980's, concluding with the climactic struggle over the Mort Bay public housing project. Chapter seven looks at the diaspora of the Labor Left in Leichhardt at the end of the 1980's as the branch membership declined and many sought out political alternatives to the ALP. Part IV brings the thesis to its conclusion, focussing on the complexities and ambiguities of the middle class Left and drawing out the main socio-political themes of the two decades.

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 three-dimensional thermal maturity pattern has been investigated and the hydrocarbon generation potential assessed for the Permian and Triassic sequences of the southern Bowen and northern Gunnedah Basins and the lower part of the overlying Jurassic Cretaceous Surat Basin sequence in northern New South Wales. An oil-source rock correlation also has been investigated in the Gunnedah Basin. Vitrinite reflectance measurements were conducted on 256 samples from 28 boreholes. A total of 50 of these samples were subjected to Rock-Eval pyrolysis analysis, and 28 samples extracted for additional organic geochemical studies (GCMS). A re-evaluation of the stratigraphy in the southern Bowen Basin and a stratigraphic correlation between that area and the northern Gunnedah Basin was also included in the study. An overpressured shaly interval has been identified as a marker bed within the lower parts of the Triassic Moolayember and Napperby Formations, in the Bowen and Gunnedah Basins respectively. Suppressed vitrinite reflectance in the Permian sequence was used as another marker for mapping the stratigraphic sequence in the southern Bowen Basin. The Permian sequence in the Bowen Basin thins to the south, and probably pinches out over the Moree High and also to the west. The coal-bearing Kianga Formation is present in the north and northeastern parts of the study area. A disconformity surface between Digby and Napperby Formations in the Gunnedah Basin is probably time-equivalent to deposition of the Clematis Group and Showgrounds Sandstone in the Bowen Basin. The Clematis Group is absent in the study area, and the Moolayember Formation considered equivalent to the Napperby Formation. Although in many cases core samples were not available, handpicking of coal or shaly materials from cuttings samples where geophysical log signatures identify these materials helped in reducing contamination from caved debris. Histogram plots of reflectance also helped where the target and caved debris were of similar lithology. Vertical profiles of the vitrinite reflectance identified suppressed intervals in the study area due to marine influence (Back Creek Group and Maules Creek Formation) and liptinite rich source organic matter (Goonbri Formation). The suppression occurs due to the perhydrous character of the preserved organic matter. High reflectance values were noted within intrusion-affected intervals, and two types of igneous intrusion profiles were identified; these are simple and complex profiles. An isoreflectance map for the non-suppressed interval at the base of the Triassic sequence in the southern Bowen Basin shows that the organic matter is mature more towards the east close to the Goondiwindi Fault, and also towards the west where the Triassic sequence directly overlies the basement. High values also occur over the Gil Gil Ridge in the middle, to the south over the Moree High, and to the north where the sequence is thicker. The reflectance gradient in the suppressed intervals is higher than in the overlying non-suppressed sequences, especially when the rank has resulted from burial depth. Tmax from Rock-Eval pyrolysis was found to be lower in the perhydrous intervals, and was high in mature and igneous intrusion-affected intervals. Based on the source potential parameters, the Permian Back Creek Group is a better source than the Kianga Formation, while the Goonbri Formation is better than the Maules Creek Formation. The Triassic Napperby Formation has a fair capacity to generate oil, and is considered a better source rock than the equivalent Moolayember Formation. The Jurassic Walloon Coal Measures is a better source than Evergreen Formation, and has the best source rock characteristics, but is immature. The Rock-Eval S1 value shows better correlation with extracted hydrocarbon compounds (saturated and aromatics) than the total extractable organic matter. This suggests that solvent extraction has a greater ability to extract NSO compounds than temperature distillation over the Rock-Eval S1 interval. Terrestrial organic matter is the main source input for the sequences studied. This has been identified from organic petrology and from the n-alkane distributions and the relatively high C29 steranes and low sterane/hopane ratios. The absence of marine biomarker signatures in the Permian marine influenced sequence, could be attributed to their dilution by overwhelming amounts of non-marine organic matter. A mainly oxic to suboxic depositional environment is inferred from trace amounts of 25-NH, BNH and TNH. This is further supported by relatively high pr/ph ratios. Although C29/C30 is generally regarded as an environmental indicator, high values were noted in intrusion-affected samples. The 22S and 20S ratios were inverted ????reaches pseudo-equilibrium???? in such rapidly heated, high maturity samples. The ratio of C24 tetracyclic terpane to C21-C26 tricyclic terpanes decreases, instead of increasing, within the Napperby Formation close to a major igneous intrusive body. The 22S ratio, which is faster in reaction than the other terpane and sterane maturity parameters, shows that the Permian sequence lies within the oil generation stage in the Bowen Basin, except for a Kianga Formation sample. The Triassic sequence is marginally mature, and the Jurassic sequence is considered immature. In the Gunnedah Basin, the Permian sequence in Bellata-1 and Bohena-1, and the Triassic sequence in Coonarah-1A, lie within the oil generation range. In the intrusion-affected high maturity samples, the ratio is reaches pseudo-equilibrium. This and other terpane and sterane maturity parameters are not lowered (suppressed) in the perhydrous intervals. The ???????? sterane ratio, however, is slowest in reaction to maturity, and variations in low maturity samples are mainly due to facies changes. Diasterane/sterane ratios, in the current study, increase with increasing TOC content up to 5% TOC, but decrease in rocks with higher TOC contents including coals. Highly mature samples, as expected, in both cases are anomalous with high ratios. Calculated vitrinite reflectance based on the method of Radke and Welte (1983), as well as MPI 1 and MPI 2, shows the best comparison to observed values. These aromatic maturity parameters are lowered within the reflectance-suppressed intervals. Oil stains in the Jurassic Pilliga Sandstone in the Bellata-1 well have been identified as being indigenous and not due to contamination. The vitrinite reflectance calculated to the oil stain suggests that the source rock should be within a late mature zone. Such high maturity levels are only recognised within intrusion-affected intervals. A close similarity between the oil stain sample and the intruded interval of the Napperby Formation is evident from the thermal maturity and biomarker content. Hydrocarbon generation and expulsion from the lower part of the Napperby Formation as a result of igneous intrusion effects is suggested as the source of the oil in this particular occurrence. Terpane and sterane maturity parameters increase with increasing burial depth in the intervals with suppressed (perhydrous) vitrinite reflectance. The generation maturity parameters also increase through intervals with perhydrous vitrinite, which suggests that hydrocarbons continue to be generated and the actual amount is increasing even though traditional rank ????????????stress???????????? maturity parameters are lowered. Accordingly, the Permian sequences in the lower part of the Bowen Basin are at least within the peak oil generation zone, and probably within late oil generation in the north and northeast of the study area. To generate significant amounts of hydrocarbon, however, the thickness of the shaly and coaly intervals in the Permian sequence is probably a critical parameter. In the Gunnedah Basin, a significant amount of hydrocarbon generation is probably only possible as a result of igneous intrusions.
