The SNEFB consists of the Tamworth Belt and Tablelands Complex that are separated by the Peel Fault. The Tablelands Complex to the east of the Peel Fault represents an accretionary wedge, and the Tamworth Belt to the west corresponds to the forearc basin. A total of five east-north-east trending gravity profiles with around 450 readings were conducted across the Tamworth Belt and Gunnedah Basin. Seven ground magnetic traverses of a total length of 60 km were surveyed across the bounding faults of the Tamworth belt, of which five were across the Peel Fault and two were across the Mooki Fault. The gravity data shows two distinct large positive anomalies, one over the Tamworth Belt, known as the Namoi Gravity High and another within the Gunnedah Basin, known as the Meandarra Gravity Ridge. All gravity profiles show similarity to each other. The magnetic data displays one distinct anomaly associated with the Peel Fault and an anomaly immediately east of the Mooki Fault. These new potential field data are used to better constrain the orientation of the Peel and Mooki Faults as well as the subsurface geometry of the Tamworth Belt and Gunnedah Basin, integrating with the published seismic data, geologic observations and new physical properties data. --Magnetic anomalies produced by the serpentinite associated with the Peel Fault were used to determine the orientation of the Peel fault. Five ground magnetic traverses were modelled to get the subsurface geometry of the serpentinite body. Modelling results of the magnetic anomalies across the Peel Fault indicate that the serpentinite body can be mostly modelled as subvertical to steeply eastward dipping tabular bodies with a minimum depth extent of 1-3 km, although the modelling does not constrain the vertical extent. This is consistent with the modelling of the magnetic traverses extracted from aeromagnetic data. Sensitivity analysis of a tabular magnetic body reveals that a minimum susceptibility of 4000x10⁻⁶cgs is needed to generate the observed high amplitude anomalies of around 2000 nT, which is consistent with the susceptibility measurements of serpentinite samples along the Peel Fault ranging from 2000 to 9000 x 10⁻⁶ cgs. Rock magnetic study indicates that the serpentinite retains a strong remanence at some locations. This remanence is a viscous remanent magnetisation (VRM) which is parallel to the present Earth's magnetic field, and explains the large anomaly amplitude over the Peel fault at these locations. The remanence of serpentinite at other localities is not consistent enough to contribute to the observed magnetic anomalies. A much greater depth extent of the Peel Fault was inferred from gravity models. It is proposed that the serpentinite along the Peel Fault was emplaced as a slice of oceanic floor that has been accreted to the front of the arc, or as diapirs rising off the serpentinised part of the mantle wedge above the supra subduction zone. / Magnetic anomalies immediately east of the Mooki Fault once suggested to be produced by a dyke-like body emplaced along the fault were modelled along two ground magnetic traverses and three extracted aeromagnetic lines. Modelling results indicate that the anomalies can be modelled as an east-dipping overturned western limb of an anticline formed as a result of a fault-propagation fold with a shallow thrust step-up angle from the décollement. Interpretation of aeromagnetic data and modelling of the magnetic traverses indicate that the anomalies along the Mooki Fault are produced by the susceptibility contrast between the high magnetic Late Carboniferous Currabubula Formation and/or Early Permian volcanic rocks of the Tamworth Belt and the less magnetic Late Permian-Triassic Sydney-Gunnedah Basin rocks. Gravity modelling indicates that the Mooki Fault has a shallow dip ( ̃25°) to the east. Modelling of the five gravity profiles shows that the Tamworth Belt is thrust westward over the Sydney-Gunnedah Basin for 15-30 km. --The Meandarra Gravity Ridge within the Gunnedah Basin was modelled as a high density volcanic rock unit with a density contrast of 0.25 tm⁻³, compared to the rocks of the Lachlan Fold Belt in all profiles. The volcanic rock unit has a steep western margin and a gently dipping eastern margin with a thickness ranging from 4.5-6 km, and has been generally agreed to have formed within an extensional basin. --The Tamworth Belt, being mainly the product of volcanism of mafic character and thus has high density units, together with the high density Woolomin Association, which is composed chiefly of chert/jasper, basalt, dolerite and metabasalt, produces the Namoi Gravity High. Gravity modelling results indicate that the anomaly over the Tamworth Belt can be modelled as either a configuration where the Tablelands Complex extends westward underthrusting the Tamworth Belt, or a configuration where the Tablelands Complex has been thrust over the Tamworth Belt. When the gravity profiles were modelled with the first configuration, the Peel Fault with a depth extent of around 1 km can only be modelled for the Manilla and Quirindi profiles, modelling of the rest of the gravity profiles indicates that the Tablelands Complex underthrust beneath the Tamworth belt at a much deeper location. / Mode of access: World Wide Web. / xi, 242 leaves ill., maps

The goal of this thesis is to examine the editorial position of the Sydney Morning Herald, Australia's oldest continually produced newspaper, as a way of examining the character of colonial liberalism. Analysis will proceed by way of close scrutiny of key issues dealt with by the Sydney Morning Herald, including: state-aid to churches; education policy; free trade; land reform; the antitransportation movement; issues surrounding political representation; and the treatment of Chinese workers. Such analysis includes an appraisal of the views of John Fairfax, proprietor from 1841 to his death in 1877, and the influences, particularly religious nonconformity, which shaped his early journalism in Britain. Another key figure in the thesis is John West, editor 1854-1873, and again his editorial stance will be related to the major political and religious movements in Britain and Australia. Part of this re-evaluation of the character of colonial liberalism in the thesis provides a critical study of the existing historiography and calls into question the widely held view that the Sydney Morning Herald was a force for conservatism. In doing so, the thesis questions some of the major assumptions of the existing historiography and, while doing justice to colonial context, attempts to contextualise colonial politics with the broader framework of mid nineteenth-century Western political thought.

This thesis presents the results of a computational study on salt transport and accumulation in crop root zone. The main objective of this study is to examine the impacts of past land use on the environment and to examine the effect of irrigation water on the rising of groundwater level and the subsequent salinity problem in rice growing area under given climatic conditions. A special focus has been such impacts in the Wakool irrigation area, NSW, Australia. To this end, a computational model for the assessment and prediction of salinisation in agricultural areas has been developed. This modelling system consists of a land surface scheme (ALSIS) for simulating unsaturated soil moisture and moisture flux, a groundwater flow model (MODFLOW) for estimating the spatial and temporal variations of groundwatertable, a surface flow model (DAFLOW) for calculating water flow in river networks, a module for calculating solute transport at unsaturated zone and a 3-D model (MOC3D) for simulating solute transport in groundwater as well as a module for calculating the spatial and temporal distributions of overland flow depth during wet seasons. The modelling system uses a finite difference linked technique to form a quasi three dimensional model. The land surface scheme is coupled with the groundwater flow model to account for the interactions between the saturated and unsaturated zones. On the land surface, the modelling system incorporates a surface runoff model and detailed treatments of surface energy balance, which is important in es-timating the evapotranspiration, a crucial quantity in calculating the moisture and moisture fluxes in the root zone. Vertical heterogeneity of soil hydraulic properties in the soil profile has been considered. The modelling system has the flexibility of using either Clapp and Hornberger (1978), Broadbridge and White (1988), van Genuchten (1980) or Brooks and Corey (1966) soil water retention models. Deep in the soil, the impact of groundwater table fluctuation on soil moisture and salinity in the unsaturated soil is also included. The calibration and validation for the system have been partially performed with observed groundwater levels in the Wakool irrigation area. The applications of the model to theWakool region are made in two steps. Firstly, a one-dimensional simulation to a selected site in the Wakool irrigation area is carried out to study the possible impact of ponded irrigation on salinisation and the general features of salt movement. Secondly, a more realistic three-dimensional simulation for the entire Wakool region is performed to study the spatial and temporal variations of root zone soil salinity under the influence of past land use from 1975 to 1994. To allow the assessment and prediction of the effects of ponded rice irrigation water (which contains salt) on soil salinity in the area, several hypothetical scenarios using different qualities of water for rice irrigation are tested. To facilitate comparative analysis of different scenarios, a base case is defined, for which irrigation water is assumed to be free of salt. The simulated results show that irrigation increases overall recharge to groundwater in the Wakool irrigation area. The use of ponded irrigation for rice growing has a substantial effect on salt accumulation in the root zone and the rising of groundwater level, indicating that irrigation at rice bay is a major budget item for controlling soil salinity problem in the local area.

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.

Since at least the 1970s Australia has, as a nation, officially declared itself to be ‘multicultural’ and has adopted ‘multiculturalism’ as the approach to its increasingly culturally diverse population. Since then, multiculturalism in Australia, as elsewhere in the western world, has come under sustained critique by both those who think it has ‘gone too far’, and those who think it has ‘not gone far enough’. These critiques have left many wondering whether multiculturalism is still an appropriate and valuable response to cultural diversity for both governments/the state and the populations who contend with cultural diversity as part of their everyday lives. This study attempts to move beyond these critiques and proposes a local place-bound study as one way in which we might further our understandings of multiculturalism in the Australian context and capture some of the complexities elided by these nonetheless useful critiques. The study draws on both textual and ethnographic research material, and employs discursive and deconstructive techniques of analysis to achieve this. The population of the regional centre of Griffith in the Riverina region of New South Wales is culturally diverse. Griffith is located within Wiradjuri country and became home to large numbers of non-Indigenous people after the establishment of the Murrumbidgee Irrigation Scheme in the 1910s. It continues to be a destination of choice for immigrants, largely because of the availability of work, particularly in agricultural and related industries. The study reveals that in Griffith multiculturalism is generated, negotiated and performed at the local level, in and through the everyday lives of local people, as much as it is through government intervention. It is part of the lived experience of people in culturally diverse Griffith. The kind of multiculturalism they live can be seen to be positive, pervasive and dynamic and it is something that is deemed to be of great value. They have embraced the idea of multiculturalism and of their community as multicultural to the extent that it is an important part of how they see themselves. While Australian Federal Government conceptions of multiculturalism clearly inform local discourses, with all the limitations this can bring, the conservative understandings articulated federally are made redundant by local manifestations of multiculturalism in Griffith, where there is a desire to both foster and further multiculturalism. The case of Griffith suggests that there is hope for multiculturalism and that multiculturalism can still inform an ethical mode of engagement for people from diverse cultural and ethnic traditions. Australia, however, also has an Indigenous past and present and this continues to pose the ultimate challenge to and for multiculturalism, including in Griffith. / Doctor of Philosophy (PhD)

The European rabbit lives in defined social groups of between two and about twenty individuals. There are distinct social hierarchies within each group. Rabbits are known to scent-mark their environment with secretions from several glands, and the secretion of the submandibular cutaneous gland is strongly correlated with social status. Dominant, male rabbits have a higher secretory activity of the gland, and show much more scent-marking behaviour than do any other individuals within the social group. This study was principally conducted at Hope Farm, Cattai National Park in New South Wales, Australia.The proteinaceous components of the secretion varied between individuals, but the protein profile of an individual did not change over time.It was found that dominant rabbits chin mark preferentially at the entrances to warrens, and at the boundaries of their territory.The work in this study provides new insights into the way that rabbit semiochemical messages work. The difference between the secretion of a subordinate and a dominant rabbit appears to be due to the presence or absence of one compound, 2-phenoxy ethanol. This compound, with known fixative properties, supports the idea that the only difference between dominant and subordinate secretions is whether or not they persist in the environment after marking. Such a mechanism for asserting dominance may be much more common in mammals than is apparent from the published literature / Doctor of Philosophy (PhD)
