Contaminated sediments pose a direct risk to sediment fauna and have the potential to affect other benthic assemblages. Disturbances that resuspend and remobilise contaminants may impact on filter-feeding, hard-substrate organisms that live immediately above sediments. This thesis uses laboratory and field manipulations to examine the impact of metal-contaminated sediments on sediment fauna and hard-substrate fauna simultaneously. It also compares the response of assemblages to metal contamination in a temperate and polar ecosystem. Simulated resuspension exposures in the laboratory indicated that contaminated sediments have the potential to affect hard-substrate organisms. Spirorbid polychaetes responded to both aqueous metals and to resuspended, particulate-bound metals. Impacts on hard-substrate fauna were however, not observed in manipulative field experiments using metal-spiked sediments. The recruitment and cover of hard-substrate organisms were either not affected or enhanced above contaminated sediments. In contrast, metal contamination had direct negative effects on sediment fauna, with a reduction in the abundance of most taxa. Results suggest that sediment fauna may interact with hard-substrate fauna through physical and/or biological mechanisms. In a reciprocal transplant experiment, established Antarctic hard-substrate assemblages were also unaffected by contaminant concentrations at an impacted site. Overall, metal-contaminated sediments are unlikely to pose as serious a threat to hard-substrate fauna as they do to sediment fauna. Contaminated sediments are not restricted to industrialised regions, and human activities in Antarctica have resulted in localised contamination near research stations. Although Antarctic assemblages are thought to be more sensitive than temperate assemblages to contaminants, few studies have explicitly examined this. Little evidence was found to support the theory that Antarctic assemblages are more susceptible to contaminated sediments. The response of Antarctic and temperate assemblages in the field to metal-contaminated sediments over a 10-11 month period was comparable. Responses were of a similar magnitude, despite differences in the composition of assemblages. In 10-d toxicity tests, the mortality of a common Antarctic hard-substrate organism was relatively insensitive to aqueous Cu, Zn and Pb. These results suggest that using current sediment quality guidelines from Australia may be a useful screening tool to assess the risk associated with contaminated sediments in Antarctica.

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.

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.

This thesis explores the team identification of fans of a new sport team, using social identity theory. As there is limited research on fans of new sport teams, this study sought to redress this situation by seeking to explain and measure new team identification. Through investigating new team identification, this study extends current applications of social identity theory and understanding of fans of a new sport team. Additionally, by measuring new team identification, this thesis contributes a valid and reliable measure of the construct, and discovery of key themes driving the formation and development of new team identification. A mixed-method research design was used to investigate the central thesis topic. A case study of members of a new sport team, Sydney FC, provided the sample population. The research design included two surveys, administered at the end of the new team’s first and second seasons, respectively, in addition to twenty-one interviews undertaken to deepen understanding of new team identification. The Sports Spectator Identity Scale (SSIS) was used to measure new team identification and test for differences in identity strength based on participant characteristics. Results indicated that three defining behaviours provided the basis for the formation of new team identification. These were termed: Football first, Origin and Occasion. Measurement of new team identification using the SSIS validated the model in a new team context; however, the value of victory and the identification of rival groupings did not relate strongly to the construct. Member identity strength was significantly influenced by age, salary, membership category and games attended. Five behaviours underpinned the development of new team identification; these were termed: Searching, Expression, Eagerness, Names and Faces, and Spruiking. Social identity theory provided a useful framework to explore the formation and extent of new team identification. The formation of new team identification was strongly influenced by support of football, in this case. The implementation of the SSIS to measure new team identification extended its previous applications. Participant characteristics exerted a clear influence on the strength of new team identification. Members engaged in additional teamrelated behaviours as their new team identification increased and they developed multi-faceted and socially important bonds. Stemming from the key thesis findings, the conceptual outcomes provided a significant contribution to current literature exploring members of new sport teams. Furthermore, the nuanced differences between identification with new and established teams provide a distinct agenda for future research into new sport teams.

AIMS:The project examines the perceptions of significant stakeholders in the Catholic Education system concerning the nature, outcomes and effectiveness of the implementation of the Quality Assurance Processes developed by the Catholic Education Office (CEO), in the Archdiocese of Sydney. The study identifies factors that were assisting or hindering the effective implementation of these processes as they existed in 1996. It offers suggestions and recommendations for a future and more effective implementation of these processes. SCOPE This research is qualitative in nature, and uses interview as the main source of data collection. The Catholic schools selected for this study are those that have been involved in the implementation of the first Cycle of the Quality Assurance Processes of the CEO, Sydney. Care was taken to select two schools from each of the three Regions under which the Catholic schools in the Archdiocese of Sydney are presently organised. CONCLUSIONS The achievement and maintenance of quality outcomes has always been an integral part of Catholic Education. Through the brief historical background, this study has revealed that leaders in Catholic Education in Sydney have always sought to achieve and maintain quality outcomes since the establishment of the first schools, up until the implementation of the current quality assurance processes. This study found that the current form of Quality Assurance Processes is a most effective means of achieving and maintaining quality outcomes in the present-day Catholic education system. The Processes are professionally articulated in context with current practices, and have the potential to enhance accountability, credibility and development of both the personnel and the schools system. The implementation of the Quality Assurance Processes, to a great degree, has been effective and successful, the present study has shown that, stakeholders are becoming more and more aware of the actual nature and outcomes of these processes. The study also found great optimism among in the key player about the future of the Processes and has concluded that they well received and appreciated across the system. There were a few concerns about the clarity of aims and objectivity, the link between the different processes, and the apparently high and technical terms involved in naming/describing these Processes. The study has, therefore, concluded further that the Processes need streamlining, regular reviews and training programs to strengthen the practice and consolidate the gains and achievement. The implementation of Cycle 2 with appropriate modification is desirable.

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

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

Master of Arts / This work is the history of a particularly singular and strong human enterprise. Until the advent of several more recent interpretative works, Australian transport historiography has heavily emphasised engineering and operational development without examining the contextual social and economic forces. The Manly Ferry, with its unique contribution to the history of Sydney's development as a suburban city, provides a distinctive microcosmic example with which to illustrate the evolution of an urban society - with its emphasis on mobility - in the wake of the industrial revolution.

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