A 'civilized' drink and a 'civilizing' industry: wine growing and cultural imagining in colonial New South Wales

McIntyre, Julie Ann January 2009 (has links)
Doctor of Philosophy (PhD) / My starting point for this thesis was the absence of a foundation history of Australian wine growing conducted by an historian rather than researchers in other disciplines or the media. I have used existing work on wine history in New South Wales from 1788 to 1901 alongside a significant body of new research to create an historical argument suitable for incorporation into more broadly-themed narratives of Australian history and to inform studies of wine growing in other academic fields. My main argument is that although wine growing proved of little economic value in colonial primary production compared with nation-building commodities - such as pastoralism, wheat growing and gold - advocates of the cultivation of wine grapes believed wine growing embodied beneficial, even transformative, cultural value so they persisted in attempting to create a ‘civilizing’ industry producing a ‘civilized’ drink despite lacklustre consumption of their product and very modest profits. Several times, from 1788 to 1901, these advocates spoke out or wrote about wine and wine growing as capable of creating order in a wild or ‘savage’ landscape and within a settler society shaped culturally by shifting adaptations to both imported and ‘native’ influences in agriculture as well as alcohol production, consumption and distribution. While the methodological framework employed here falls mainly within cultural and economic history, sociological theories have contributed to findings on causation. The result is a comprehensive narrative of colonial wine growing in New South Wales enriched by links to key developments in Australian colonial history and with reference to wine growing in other British colonies or former territories.

A late quaternary palaeoenvironmental investigation of the fire, climate, human and vegetation nexus from the Sydney basin, Australia

Black, Manu, School of Biological, Earth & Environmental Sciences, UNSW January 2006 (has links)
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.

Islamic revivalism: a study of the Tablighi Jamaat in Sydney

Ali, Jan Ashik, School of Sociology & Anthropology, UNSW January 2006 (has links)
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.

Parameter estimation using a genetic algorithm for complex catchment modelling systems.

Fang, Tianjun, Civil & Environmental Engineering, Faculty of Engineering, UNSW January 2007 (has links)
Implementation of physically distributed catchment modelling systems reshapes the fundamental philosophy of traditional calibration approaches by supporting the concept of equifinality. Arising from the concept of equifinality, alternative behavioural parameter sets within a given catchment modelling system structure can generate similar levels of simulation performance. This concept is motivated by the existence of a variety of uncertainties associated with a complex catchment modelling system, such as an imperfect model structure, measurement errors in both the input data and the recorded flows, and unknown, or poorly defined, interactions among parameters. However, the difficulty of searching for behavioural parameter sets increases as the complexity of the catchment modelling systems increases. This study undertook an investigation on the feasibility and robustness of a real-value coding genetic algorithm (GA) for calibrating the physically distributed Storm Water Management Model (SWMM) using the Centennial Park catchment in Sydney as a case study. It was found that a real-value coding GA was a robust technique suitable to search for behavioural parameter sets and, in particular, it was found that this approach was capable of identifying the promising range of values for spatially variable parameters. Moreover, the widespread use of physically distributed catchment modelling systems has highlighted the importance of estimating the uncertainty in the parameter values and in the predictions obtained from a complex catchment modelling system as well as in catchment averaged, or lumped, systems that have been the focus of many previous studies. Bayesian inference has been shown to be a tool suitable for parameter uncertainty estimation in catchment modelling. However, the application of Bayesian inference faces difficulties in complex high-dimensional systems where there is little if any a priori knowledge about the proposal distribution of the parameters. In this study, a real-value coding GA was used to undertake uncertainty estimation on spatially variable control parameters with little a priori knowledge about the proposal distribution of parameters. After 50,000 evaluations, the marginal posterior distributions of spatially variable parameters which are associated with behavioural parameter sets were identified. The performance of a behavioural parameter set under a range of hydrological conditions was evaluated. Updating of the marginal distributions of these control parameters was implemented by adding additional calibration data. Interactions among the spatially variable control parameters were investigated also. Results based on the Pearson Correlation method indicate no clear relationship between any two control parameters. However, a methodology to detect relationships among groups of parameters was developed. Application of this methodology suggests that the simulation performance of SWMM was influenced by combinations of parameter values rather than values of the individual parameters. Finally, the predictive uncertainty associated with the existence of behavioural parameter sets was considered. A number of alternative strategies were used to evaluate the predictive performance. Consideration of the results suggests that use of a small number of parameter sets randomly selected from the large number of behavioural parameter sets was the best strategy in terms of efficiently obtaining predictive performance.

Eutrophication and excessive Macroalgal growth in Lake Macquarie, New South Wales

Nicholls, David John, School of Biological Science, UNSW January 1999 (has links)
In response to concern that excessive macroalgal growth and accumulation was occurring in some inshore areas of Lake Macquarie, the distribution, abundance and seasonality of macroalgae was investigated in relation to nutrient input and power station cooling water. Macroalgal dry weight biomass was measured at ten sites on a monthly basis for two years, with an analysis of community structure conducted using Multi-Dimensional Scaling. The macroalgal community in Lake Macquarie was typical of those found in other New South Wales coastal lagoons, exhibiting considerable spatial and temporal variation. A close similarity was observed in macroalgal community structure at sites affected by urban nutrient input, these being characterised by a high biomass often attributable to only one or two species. These nuisance macroalgae were mostly green algae, which were almost entirely absent from other sites. Biomass at sites affected by urban nutrient input was generally within the range documented for eutrophic estuaries elsewhere. Analysis of macroalgal community structure showed no evidence of large-scale changes macroalgal communities attributable to the effects of power station cooling water except within 500m of the outfall. At sites affected by a 1-2??C temperature increase, community structure and the magnitude of the biomass were similar to sites deemed as being relatively free of human impact. A reduction in species diversity occurred only within the immediate discharge zone, where water temperatures were approximately 6??C above ambient temperatures. Excessive growth of nuisance macroalgal species was not observed at any of the sites influenced by power station cooling water. There were no distinct patterns in seasonality of macroalgal growth in this study, though the greatest biomass appeared to occur in spring. The irregular temporal variation in macroalgal growth suggests that the most significant factors affecting growth occur on a time scale of weeks to months. It is therefore likely nutrient input to the nearshore through surface runoff is an important influence on the distribution and abundance of macroalgae in Lake Macquarie. This emphasises the need to reduce nitrogen and phosphorus input from urban sources in Lake management.

The professional life-cycles and professional development of adult teachers of English to speakers of other languages (TESOL)

Waites, Carol Katherine, Education, Faculty of Arts & Social Sciences, UNSW January 1999 (has links)
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.

To labour seriously : Catholic sisters and social welfare in late nineteenth century Sydney

Hughes, Lesley Patricia, School of Social Work, UNSW January 2002 (has links)
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.

Networks for regional development : case studies from Australia and Spain

Martinez-Fernandez, Cristina, Built Environment, Faculty of Built Environment, UNSW January 2001 (has links)
This study investigates the role of regional networks for economic development (RENEDs) in regions suffering from industrial dislocation. It proposes that RENEDs significantly affect regional development. It also investigates the aspects of RENEDs that promote interorganisational collaboration on projects, and examines how RENEDs foster and manage them. The research uses a case study approach, and presents two regions suffering from the decline of their main economic source. These regions are the Hunter region of New South Wales (Australia) and the Le??n province of Castilla Y Le??n (Spain). A pilot study and a survey were conducted in both regions. Three types of analysis were applied: network, statistical and qualitative. The research method makes it possible to replicate research and develop a theory of regional networks for economic development. The results show that success of RENEDs is determined by capital investment generated by the projects, their influence in changing the economic bases of the regions, and the improvement to regional network capital. This study found that frequency of communication is a structural element that significantly affects the production of projects. However, other variables affect projects, such as external pressures from globalisation, government policies and ideologies, and internal constraints from the public, private and civic sectors. This thesis concludes that RENEDs have an important role in regional planning through the formulation of specific projects that target economic disparity. RENEDs represent a system of relationship that enrich the network capital of the regions as an important asset for their future.

Effects of estuarine acidification on survival and growth of the Sydney rock oyster Saccostrea glomerata

Dove, Michael Colin, Geography Program, UNSW January 2003 (has links)
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.

Petroleum geology of the Gunnedah-Bowen-Surat Basins, Northern New South Wales : stratigraphy, organic petrology and organic geochemistry

Othman, Rushdy, School of Biological, Earth & Environmental Sciences, UNSW January 2003 (has links)
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.
