- Description: This thesis examines the educational experiences of some young people living in the Hepburn Shire, a Local Government Area (LGA) in the Central Highlands of Victoria. These young people were in various stages of disengaging from the mainstream education on offer in the shire. The research came about via consultation between the secondary school and Federation University in response to data from the Department of Education and Training (DET) showing that the Hepburn area had the lowest school attendance figures of the eleven LGA’s in the Grampians region. The school was interested in the reasons behind the lower figures and sought to gather some further information which might shed light on the experiences of young people who had difficulty in connecting, or staying connected to, school. It was hoped that the resultant findings would inform the approach taken by the schools in offering appropriate programs to support people to re-engage with school. Thus, the research question underpinning this research is: What are the key reasons that school attendance has been identified as being lower in the Hepburn Shire Local Government Area than in other parts of the Grampians region? A critical ethnographic study was undertaken comprised of participant observation, facilitated by the researcher being situated within the school, and a series of semi-structured interviews conducted with young people (of secondary school age), families, teachers, Principals, support staff including welfare providers and a selection of other professionals working with youth and their families in the Hepburn Shire. The study revealed a complexity within the Hepburn community, where a rich diversity of views about child-raising and education was present. Such views spanned philosophies about ‘unschooling’, the benefits of home-schooling, and a sense of permissiveness about not attending school each day. Further, there seemed to be a tendency within the school (both by teachers and other professionals working with youth) to talk about disengaged students and families of nonattending students in terms of deficit: there was something lacking with them, parenting skills, work ethic, behavioural or emotional regulation, that was viewed as contributing to the students’ poor attendance. Finally, the centrality of the teacher-student relationship to both student engagement and disengagement was evident in the conversations with young people and their families. Building respectful, reciprocal relationships with at least one key member of staff seems to be a major protective factor against disengagement. And further, seems to be a pre-requisite for those students who are entering the school for the first time, or who are re-entering after a significant absence.

Historical mine sites as modern-day sources of contamination : Measurement and characterisation of arsenic in historical gold mine wastes to identify the potential for mobility and human exposure
- Authors: Martin, Rachael

- Description: Centuries of metalliferous mining activities have resulted in a legacy of contamination throughout the world. Unremediated mine wastes and tailings, as well as contaminated soils, water and sediments, represent ongoing sources of environmental degradation and human exposure, long after mine closure and abandonment. Despite global concern over these contaminant sources, there remain uncertainties surrounding the nature of human exposure to mine wastes and their toxicologically relevant characteristics. As urbanisation expands into areas proximal to abandoned mine sites, an understanding of the human-contaminant interface at this boundary is critical for assessing the potential health risks. This thesis addresses this knowledge gap by investigating the importance of particle size as a factor governing the distribution of metals and metalloids in historical gold mine wastes in regional Victoria, Australia, with an emphasis on arsenic as a contaminant of potential concern. By characterising those particle size fractions that are relevant to dust mobilisation and human exposure, this thesis examines the human-contaminant interface using a multi-pathway approach. In particular, this thesis focuses on the potential for exposure via inhalation of mine waste particulates. The outcomes of the studies presented in this body of work demonstrate that historical gold mine wastes in regional Victoria represent a source of readily ingestible and inhalable particulates characterised by extremely elevated levels of arsenic (and other contaminants) well above their bulk (in situ) concentrations. Although lung bioaccessibility testing and mineralogical analyses revealed that most of the arsenic in inhalable dust has been naturally immobilised, the lung-soluble fraction should be considered when undertaking risk assessments for chronic exposure. This thesis provides a framework for the development of targeted management strategies for unremediated historical gold mining wastes in regional Victoria. The findings suggest there is a need for environmental regulations to shift from generic guideline values to exposure-specific guidelines that more accurately reflect the human health risks posed by historical mine sites. This thesis has emphasised the notion that in order for remedial action to accurately match the level of risk, the sourcepathway- receptor linkage must be evaluated using a systematic size-resolved approach.

- Description: Accurate rainfall prediction is a challenging task because of the complex physical processes involved. This complexity is compounded in Australia as the climate can be highly variable. Accurate rainfall prediction is immensely benecial for making informed policy, planning and management decisions, and can assist with the most sustainable operation of water resource systems. Short-term prediction of rainfall is provided by meteorological services; however, the intermediate to long-term prediction of rainfall remains challenging and contains much uncertainty. Many prediction approaches have been proposed in the literature, including statistical and computational intelligence approaches. However, finding a method to model the complex physical process of rainfall, especially in Australia where the climate is highly variable, is still a major challenge. The aims of this study are to: (a) develop an optimization based clusterwise linear regression method, (b) develop new prediction methods based on clusterwise linear regression, (c) assess the influence of geographic regions on the performance of prediction models in predicting monthly and weekly rainfall in Australia, (d) determine the combined influence of meteorological variables on rainfall prediction in Australia, and (e) carry out a comparative analysis of new and existing prediction techniques using Australian rainfall data. In this study, rainfall data with five input meteorological variables from 24 geographically diverse weather stations in Australia, over the period January 1970 to December 2014, have been taken from the Scientific Information for Land Owners (SILO). We also consider the climate zones when selecting weather stations, because Australia experiences a variety of climates due to its size. The data was divided into training and testing periods for evaluation purposes. In this study, optimization based clusterwise linear regression is modified and new prediction methods are developed for rainfall prediction. The proposed method is applied to predict monthly and weekly rainfall. The prediction performance of the clusterwise linear regression method was evaluated by comparing observed and predicted rainfall values using the performance measures: root mean squared error, the mean absolute error, the mean absolute scaled error and the Nash-Sutclie coefficient of efficiency. The proposed method is also compared with the clusterwise linear regression based on the maximum likelihood estimation, linear support vector machines for regression, support vector machines for regression with radial basis kernel function, multiple linear regression, artificial neural networks with and without hidden layer and k-nearest neighbours methods using computational results. Initially, to determine the appropriate input variables to be used in the investigation, we assessed all combinations of meteorological variables. The results confirm that single meteorological variables alone are unable to predict rainfall accurately. The prediction performance of all selected models was improved by adding the input variables in most locations. To assess the influence of geographic regions on the performance of prediction models and to compare the prediction performance of models, we trained models with the best combination of input variables and predicted monthly and weekly rainfall over the test periods. The results of this analysis confirm that the prediction performance of all selected models varied considerably with geographic regions for both weekly and monthly rainfall predictions. It is found that models have the lowest prediction error in the desert climate zone and highest in subtropical and tropical zones. The results also demonstrate that the proposed algorithm is capable of finding the patterns and trends of the observations for monthly and weekly rainfall predictions in all geographic regions. In desert, tropical and subtropical climate zones, the proposed method outperform other methods in most locations for both monthly and weekly rainfall predictions. In temperate and grassland zones the prediction performance of the proposed model is better in some locations while in the remaining locations it is slightly lower than the other models.

A conceptual re-alignment of methodology underpinning tax effect accounting : An Australian exploration of the contemporary normalising effect
- Authors: Morton, Elizabeth

- Type: Text , Thesis , PhD
- Full Text:
- Description: This research examines the presence and effectiveness of the ‘normalising effect’, traditionally offered as the main justification for tax effect accounting’s (TEA) adoption. TEA can be seen as a technical facet of accounting practice, ‘normalising’ the timing differences between the accounting and taxation systems. That is, income tax is recognised according to when transactions are recognised for accounting purposes in order to ‘normalise’ reported profits, thereby reflecting an income statement focus. It has been contended that this will improve the usefulness of financial reports by ‘correcting’ misleading and ‘unreal’ fluctuations in income tax. Australia’s adoption of AIFRS in 2005 entailed a major conceptual re-alignment of the methodology underpinning TEA, moving away from the income statement focus in favour of a balance sheet focus. This implied a different normalisation emphasis. It is within this contemporary setting, based on a study of 90 companies over the two regulatory periods between 2002 and 2011 (AGAAP and AIFRS), that a quantitative measure of the presence and effectiveness of the normalising effect was undertaken, additionally considering the subsequent balance sheet impact. Effective normalisation was revealed during the AGAAP period, whilst only effective after the removal of loss makers during the AIFRS period. These findings suggest that the relaxation of recognition criteria under AIFRS may have had a meaningful impact on the effectiveness of the new standard. However, when normalisation was given a more narrow definition in light of prima facie tax, deferred taxes had a more substantial impact, particularly during the AIFRS period. Such findings are consistent with the notion thatTEA enables reported tax to be ‘as if’ it were a function of accounting, without a substantial build up on the balance sheet as a consequence. These findings have implications for evaluating the efficacy of TEA and comprehending the nature of contemporary financial statements.

A philosophical analysis of the functions and operation of due process in accounting standard setting in Australia
- Authors: Mehta, Surinder
- Date: 2016
- Type: Text , Thesis , Masters
- Full Text:
- Description: The setting of accounting standards in the Australian context has undergone significant change over the past few decades because of both the introduction of international accounting standards and the outcomes of the Corporate Law Economic Reform Program (CLERP). One major thrust of these reforms was to widen the breadth of participation and to introduce new voices into the Australian accounting standard setting regime. Though there have been recent changes to Australian accounting standard setting arrangements, due process still remains as the underlying procedure for incorporating stakeholder participation. Standard setting resides within a socio-political and economic realm which lies between a capitalistic economic individualism premised upon self-interest and interest group preferences, and an idealistic paradigm of the public interest (common good). Both notions are espoused within modern civil society and present in the formulation of policy and regulation through participation. Recent times have seen the promulgation of accounting standards given over by delegated legislation to private sector interests who compete for desired outcomes and more recently this has been entrenched within the International Accounting Standards Board (IASB) which produces International Financial Reporting Standards (IFRS). This research presents a two-fold investigation of the due process which is applied when developing accounting standards in Australia. Firstly, this study questions whether such standards provide an adequate avenue for incorporating both appropriate attributes of participation and accountability in line with the historical understanding of due process as developed through common law. Secondly, this study questions whether such standards provide an appropriate vehicle for widening participation by introducing new voices into the Australian accounting standard setting process. On the former question, common law due process resonates within a paradigm that supports fair dealing and equity between individuals with themselves and with government. On the latter question, this research identifies low and declining stakeholder participation within the due process of accounting standard setting. This is accompanied by the declining interest of previous major participants. In examining the longitudinal participation trends of submitters to the accounting standard setting regime, this research contends that the due process finds itself embedded within the confines of a procedural construct to the detriment of accommodating natural justice through a more enlightened substantive approach. As such, when considered in light of its common law roots, it fails both to provide an adequate level of openness along with accommodating only a limited opportunity to participate, specifically when taking into account opinions and interests. The very construct of common law due process rests upon its ability both to subsume participation within the decision-making process, and for that participation to be substantive in the outcome of the process. That is, such participation gives meaning to the outcome. Instead the current due process as applied within the accounting standard setting environment resonates such participation through abolitionist type approaches. Here self-interested parties compete for advantages from property rights and private benefits in line with the more modern interpretation of the public interest. The approach taken in this thesis is to consider the due process from a philosophical perspective by assessing the questions of accountability and participation within the due process in terms of civil society, the public good, economic individualism, libertarianism, liberalism, and agency, rather than to embed the discussion within the expansive existing studies concerning due process in the accounting standard setting process. The conclusion from this perspective is that due process is clearly a process past its due date.

Assessing productive soil - landscapes in Victoria using digital soil mapping
- Authors: Robinson, Nathan
- Date: 2016
- Type: Text , Thesis , PhD
- Full Text:
- Description: Spatial soil information is used to support questions on agriculture and the environment from global to local scales. Historically, soil mapping has been used to inform and guide a multitude of land users with their decisions. Demand for specific spatial soil information is increasing in response from a wider range of users operating across agricultural and environmental domains. To satisfy these demands, users must be provided with practical and relevant spatial soil information. Novel approaches are required to deal with global deficiencies in available soil information. A major limitation to this is the plethora of incongruent legacy data with poor spatial and temporal coverage. This research study initially identifies the specific needs of users for spatial soil information with a focus on the requirements of biophysical modellers. Secondly, error sources that hamper Digital Soil Mapping (DSM) are identified, described and assessed using pH in practical and relevant examples. A final aim is to spatially predict soil properties (e.g. clay mineralogy) that underpin soil chemical behaviour. This is achieved by harmonising legacy data in combination with new spectroscopy techniques and a spatial inference approach. The spatial soil information needs of biophysical modellers in Victoria, Australia were found to be consistent with global needs for information including soil water characteristics, organic carbon and effective rooting depth. To accommodate stochastic and epistemic uncertainties in spatial soil information, uncertainty frameworks proved effective to deal with, and understand the limitations of legacy data in spatial inference models. Robust and reliable spectroscopic models for properties that are linked to functions and services delivered by soil were achieved and used in 3D spatial models. These findings will enable a tactical response through the delivery of pertinent spatial soil information that is contemporary, quality assured and sought by users. Learnings presented should enable producers of spatial soil information to be more comprehensive in their delivery of products that are easy to use, accessible and understood by a growing user community.

To satisfy these demands, users must be provided with practical and relevant spatial soil information. Novel approaches are required to deal with global deficiencies in available soil information. A major limitation to this is the plethora of incongruent legacy data with poor spatial and temporal coverage. This research study initially identifies the specific needs of users for spatial soil information with a focus on the requirements of biophysical modellers. Secondly, error sources that hamper Digital Soil Mapping (DSM) are identified, described and assessed using pH in practical and relevant examples. A final aim is to spatially predict soil properties (e.g. clay mineralogy) that underpin soil chemical behaviour. This is achieved by harmonising legacy data in combination with new spectroscopy techniques and a spatial inference approach. The spatial soil information needs of biophysical modellers in Victoria, Australia were found to be consistent with global needs for information including soil water characteristics, organic carbon and effective rooting depth. To accommodate stochastic and epistemic uncertainties in spatial soil information, uncertainty frameworks proved effective to deal with, and understand the limitations of legacy data in spatial inference models. Robust and reliable spectroscopic models for properties that are linked to functions and services delivered by soil were achieved and used in 3D spatial models. These findings will enable a tactical response through the delivery of pertinent spatial soil information that is contemporary, quality assured and sought by users. Learnings presented should enable producers of spatial soil information to be more comprehensive in their delivery of products that are easy to use, accessible and understood by a growing user community.

- Description: This thesis disentangles two elements from the complex interdependent suite of key drivers of firm sophistication in capital-budgeting. Specifically, the relative sophistication of a firm (i.e. its nature) and the development level of the nation in which a firm is embedded (i.e. the nurture experienced by the firm). This research should enhance the development focus and process of nations (e.g., to what degree should national development be about raising the ability of individual firms or will raising national development act as a rising tide [that] raises all boats). The comparative data used in this study comes from 150 Australian (ASX200-index-listed) firms and 150 Sri Lankan (Colombo-stock-exchange-listed firms). The research questions are answered via a quantitative research design that uses primary and secondary data. The response rate to the questionnaire survey of firms was, 45 and 73 completed questionnaires from, respectively, Australia and Sri Lanka (an effective response rate of, respectively, 31.5 and 48.7 percent). Secondary data for 2003-12 are obtained from the ASX, CSE’s and SIRCA databases and are used to calculate return on assets, return on equity, Tobin Q, and earnings per share for the sampled firms. It was found that Australian firms tend to rely heavily on sophisticated capital-budgeting practices, but Sri Lankan relatively small firms prefer simple analysis methods and the larger firms tend to be as adept at sophisticated capital budgeting as their Australian counterparts. The choice of whether to use more sophisticated practices or simpler alternatives varies with a firm’s attributes as well as the level of economic and financial market development in its environment. Also, Australian firms tend to use capital-budget models with good-to-strong predictive power (except for ROE) and Sri Lankan firms tend to use capital-budget models with fair-to-poor predictive power. Further, the analysis of Australian firms tends to yield stronger and more statistically-significant results, than those generated by Sri Lankan firms.

Injury epidemiology among Australian female cricketers
- Authors: Perera, Nirmala
- Date: 2016
- Type: Text , Thesis , PhD
- Full Text:
- Description: Cricket is a male-dominated sport; however, its popularity among females is increasing. Like other sports, participation in cricket poses the risk of injury to players. Injury problems for female cricketers are virtually unknown, as studies examining cricket injuries include almost exclusively male participants. In other sports, the types of injuries experienced by men and women are known to be different. Therefore, a clear understanding of the extent and types of injuries sustained by female cricket players is required, to underpin appropriately targeted injury prevention strategies. This thesis provides the first detailed epidemiological profile of cricket injuries sustained by women, by: 1. conducting a systematic review describing injuries in competitive team bat or stick sports in women, to enable cricket injuries to be viewed within the perspective of wider, but relevant, injury data, 2. evaluating existing data sources relating to hospital admissions from Victoria and Queensland and successful insurance claims across Australia, 3. examining the nature and incidence of cricket injuries in elite female players using Cricket Australia’s Athlete Management System, and 4. conducting a nationwide self-report survey of injuries during the 2014–15 season. This PhD research represents participants from different levels of play, across age groups and across Australia. The findings indicate that incidence of injuries for female cricketers were higher than expected based on previous findings in comparable sports, except when considered in relation to insurance claims. The cricket injury rate across hospital presentations, insurance claims, the AMS (Fair Play AMS 2016) and self-reported survey data, each of which represents different level of the sports injury pyramid, identified all-rounders and pace bowlers as having a higher incidence of injury than players in other positions. The highest frequency of reported injuries were in the head, hands, knees and ankles. The nature of the most common injuries were dislocations/sprains/strains, fractures, muscle injury, joint injury and gradual onset injuries. At the elite-level, lumber spine stress fractures accounted for a significant amount of time-loss from the sport. In this thesis, findings from the insurance claims, self-reported survey and AMS (Fair Play AMS 2016) data indicated that most injuries were of a low severity and were more likely to be treated outside of healthcare facilities such as hospitals. In summary, patterns of the most common injuries, in terms of anatomical location and nature of the injuries, were consistent throughout community-level players with some similarities to elite-level players. However, the injury mechanisms and risk factors may differ depending on the level of competition and player’s skill. Recommendations are that ongoing injury surveillance should be conducted at all levels of the sport, and surveillance methodology should be tailored to the specific setting, personnel and available resources. Therefore, before implementing an injury surveillance system at the community-level of the sport, more research is needed to fully understand what type of injury surveillance system might be feasible and suitable in this context.

Investigations into the ecology and management of the invasive plant Galenia pubescens within the native temperate grasslands of Victoria, Australia
- Authors: Mahmood, Ako
- Date: 2016
- Type: Text , Thesis , PhD
- Full Text:
- Description: Plant invasions of natural ecosystems are one of the major threats to the conservation of biological diversity across nearly all biogeographical regions in the world. This thesis focuses on Galenia pubescens (Carpet weed) as a case study of possible approaches to the potential management of environmental weed species. G. pubescens is a woody prostrate perennial plant that is becoming a serious threat to Australian temperate grasslands, surrounding agricultural areas and conservation reserves. It is indigenous to South Africa and was first recorded in Australia in the early 1900s, and it is an aggressive competitor against native species. It is difficult to control, and little information exists about its effects on natural ecosystems, and aspects of its biology and ecology. This study has investigated some important ecological characteristics of G. pubescens’ seeds and has experimented with different management strategies in combination with chemical control. It has also considered the potential for the expansion of the distribution of this species across suitable habitat in Australia under predicted elevated CO2 and drought conditions. Seeds of G. pubescens are shown to be able to germinate over a broad range of temperatures, but short bursts (5 minutes) of high temperatures (80oC to 120oC replicating possible exposures to a fire) reduced seed germination. Seed germination was positively favored by light and declined rapidly in darkness, decreasing by > 80% at a depth of only 0.5 cm in soil. This suggests that fire regimes might be useful in removing mature plants and controlling seed numbers on the surface, and that subsequent native seeding of undisturbed areas may assist in the long-term management of this noxious weed. A trial was conducted to determine the effect of treatment with a plant essential oil (pine oil) to limit the seed germination and seedling emergence of G. pubescens. This trial showed that the effects of pine oil application were significant (P<0.05). Germination was completely inhibited by application of pine oil at 5% or higher concentrations directly to seeds, and seedling emergence was reduced by between 90 and 100% in pot trials. These outcomes demonstrate the potential viability of pine oil as a long-term control option for this species. In field-based experiments, control strategies including herbicide control with glyphosate, organic herbicide control with pine oil, the application of mulch, and the addition of native seeds to the available seedbank (and all possible combinations of these techniques), were tested. The study showed that one single treatment of a G. pubescens infestation without undertaking a secondary treatment is insufficient to control the G. pubescens infestation or to encourage native regeneration, but that a combined strategy, employing all the aforementioned techniques, is more effective. It is however suggested that full regeneration of the area may not be possible unless further restoration programs are instituted after the cycle of G. pubescens’ treatment has been completed. The thesis also assessed the control effects of chemical control combined with a prescribed spring burning. Assessment of the resulting aboveground vegetation of G. pubescens has shown that a combination of chemical control and late-spring burning can reduce the cover of non-native species such as G. pubescens, suggesting that this could be a useful tool in their management. Finally, this study has supported the view that the growth of G. pubescens will be significantly enhanced in a future climate with an enriched atmospheric CO2 concentration. These climatic changes will have important implications for management of this noxious weed in the future.

Managing risk and enhancing corporate sustainability in the Australian extractive sector : An exploratory study of leading mining and oil & gas firms in Australia
- Authors: Andeobu, Lynda
- Date: 2016
- Type: Text , Thesis , PhD
- Full Text:
- Description: Risk is an unavoidable issue in most activities of life, including business. Risk-management is increasingly a hot-button issue for stakeholders and the general public. As such, it is of rising importance in the high-risk extractive industries of mining and oil & gas. Specifically, risk-management can help firms reduce business failure-rates and enhance corporate sustainability. However, the integration of risk-management and corporate sustainability within planning, financing, and operations remains a key challenge for the sector. This research seeks to fill this gap by investigating and evaluating the current use of risk-management by extractive-sector firms to add value to stakeholders. Given that risk- management and its impact on corporate sustainability is enormous, this study will provide useful insights into the risk-management practices undertaken by extractive-sector firms in Australia and how cost-effective risk-management practices contribute to the overall enhancement of financial performance, stakeholder value and corporate sustainability of those firms. This study, after drawing data from Australia’s top 10 mining/metals firms and top 10 energy/utilities firms, uses: i) Questionnaires to give a background/context for the study, and ii) Interviews to further probe issues raised and gain a deeper understanding. The analysis in this study found that risk-management practices are: i) Perceived by management practices to contribute significantly to financial performance, stakeholder value and corporate sustainability of their firms ii) Very similar across mining firms and those in oil & gas, and iii) Too limited in application in the extractive-sector and should be extended beyond traditional hazards. Overall, it was found that risk-management systems appear to be comparable across Australia’s large mining firms and oil & gas firms. However, at a detailed level, these basic systems and structures of risk-management are adjusted and adapted to meet specific needs, corporate strategies, organisational objectives and environmental pressures. NOTE: At the request of the author, Chapters 2-12 and Appendix 7 have been removed.

Mining a rich lode : The making of the Springdallah Deep Lead Goldfield communities
- Authors: Hunt, Joan
- Date: 2016
- Type: Text , Thesis , PhD
- Full Text:
- Description: Although little material evidence survives other than mullock heaps and the occasional ruined building, a large body of archival documentation exists to help reveal the history of the deep lead gold mining communities at Springdallah. This thesis reconstructs the discovery, rise and progress of that goldfield, 30km south-west of Ballarat, through a study of family formation and community building, facilitated by micro-study tools including prosopographical and genealogical databases. At its prosperous and productive peak in the 1860s and 1870s, the communities relied totally on the mining industry for their existence. This thesis positions the alluvial deep lead gold mining industry firmly within the long but disparate historiography of Australian, and particularly Victorian, gold seeking. Unlike the many regional histories that celebrate the growth from goldfields to city status, it focuses on the miners who worked the deep leads of buried river beds, and how they and their families effected material and social change to benefit the communities they created. The findings of this thesis reveal that, in contrast to the strong Cornish presence on many Victorian goldfields, miners at Springdallah came mainly from northern England, south-west Ireland, and the lowlands of Scotland, often with extensive kinship networks. The study demonstrates that this network of communities attracted workers, usually with coal and lead mining experience, who had skills suited to conditions in the deep lead alluvial gold mining industry. According to the findings of this thesis, miners gained power within the Springdallah communities by becoming members of committees, councils, and boards of local and wider institutions. This study found that the Springdallah families were youthful, adapted well to their changed circumstances, were agents of change within their communities, and quickly took advantage of Victorian land legislation, particularly the 1869 Land Act, to take up farming properties both locally and in the north and east of the State.

Motion picture production : A micro-budget model
- Authors: Owen, Richard
- Date: 2016
- Type: Text , Thesis , PhD
- Full Text:
- Description: The film industry plays an important cultural and economic role in Australia. However, the film industry in Australia has struggled for many years under a subsidy-driven government intervention process that creates a high degree of dependence on a subsidy-centric model. Motion picture production costs worldwide have risen dramatically over the last decade with Hollywood production budgets commonly exceeding $100 million. Australia as a nation has a proven capability to produce respectable motion pictures at varying production budgets, although this capacity has become entrenched with taxpayers’ money. Historically, subsidy-driven industries in Australia trend towards collapse due primarily to cyclical fiscal deficits and changing funding imperatives at the Commonwealth level. As a PhD by exegesis, the focus of this research was to create, as well as evaluate, a new model of film production that would not be dependent on subsidies. This study evaluated a number of factors that were relevant to establishing a viable micro-budget model. Micro-budget films have received little research attention, with the focus being on major films. This research examined an alternative model, through the creation of a feature-length micro-budget film, called Stakes, and assessed it across a range of criterion to determine whether Australia’s film industry could be strengthened and potentially become self-sufficient. The resulting motion picture premièred in Australian cinemas on October 29th 2015. The justification, methods and results are discussed in detail throughout this exegesis providing strong evidence in favour of the viability for a micro-budget segment in the Australian film industry. Such a model could reduce the risk of Australia’s film industry collapsing if subsidies are reduced or abolished. Thus, this research has significant implications for Australia’s film industry and also contributes strongly to scholarship through providing crucial information on micro-budget films.

Percy : A life in China - The life and times of Percy Nettle : 1886-1964
- Authors: Nettle, Rodney
- Date: 2016
- Type: Text , Thesis , PhD
- Full Text:
- Description: This thesis is about the transnational life of Percival Edward Nettle (1886-1964), a young man born in Ballarat who moved from Australia to Shanghai at the end of 1906 on his way to San Francisco. He never did get to San Francisco but lived in and out of China until he died in 1964. This thesis tells his story and also addresses the perennial human management problem of achieving a co-operative fit between people from different cultural backgrounds. Percy Nettle achieved this fit with the Chinese through developing an exceptional rapport with Chinese people from the time he commenced working with them in 1907 on engineering projects, and later during and through wars and other civil engagements. He was a great success in China, the key to which was his skill with the language and later from his ability to culturally adapt and empathise with the people in the environments in which he was living at the time. Percy also found that his ‘Wesleyan’ approach to people conveniently dovetailed with the ‘Confucian’ values approach of the Chinese. Percy was able to communicate with Chinese people from Viceroys to infantry men and bandits and could win their trust regardless of social levels. Percy documented his ‘fitting in’ experience with the Chinese in his diaries, letters and journals over a fifty-five-year period until his death in Hong Kong in 1964. The analysis and contextualisation of his original records form the basis of this thesis and what is learned from this study of his exceptional life is the importance of achieving a very high level of cultural empathy and understanding with the people we deal with beginning with learning how to speak with them in their own language. Percy was also able to demonstrate the universal efficacy of strong ethical values even when they are transposed from one cultural setting to another.

Progressive rebels of Boy's Own Adventure? The 1935 Australian Cricket tour of India; breaking down social and racial barriers
- Authors: Ponsford, Megan
- Date: 2016
- Type: Text , Thesis , PhD
- Full Text:
- Description: In October 1935, a touring party embarked on the inaugural tour of India by an Australian cricket team. To a great, and somewhat stereotypical, extent popular representations of IndianeAustralian relations are viewed through the lens of cricket – the national game in both countries. This dissertation about a significant, yet overlooked, chapter in sporting history examines the Australian cricketers’ response to the social, racial and political hierarchies of lateecolonial India. The experience of the touring party encouraged a reeimagining of ideological perspectives and this thesis identifies a uniquely Australian subjectivity to the British colonisation of India. The tour between the colony (India) and the dominion (Australia) can be interpreted as an antie imperial gesture.

The role of cricket, itself experiencing a renaissance during the 1930s as it transformed from a largely amateur pursuit to an increasingly professional occupation is interrogated. As part of this transformation international cricket positioned itself as an increasingly politicised global entity within the broader turbulence of the firstehalf of the twentieth century. All those involved in the tour are now dead. However a close historical analysis of previously lost, highly personalised, primary material (letters, manuscripts, photographs and cricket ephemera) enables an interpretation of the players’ experience. This thesis argues that sporting events can be interpreted as cultural ciphers yet scholars and the wider sportsewriting community have neglected the historical significance of the 1935/36 tour. The unofficial status of the tour and its highly professional emphasis alienated it from the amateur ideals of Australian cricket. This transnational, multiedisciplinary approach addresses a lacunae in the professional trajectory of cricket.

- Description: In October 1935, a touring party embarked on the inaugural tour of India by an Australian cricket team. To a great, and somewhat stereotypical, extent popular representations of IndianeAustralian relations are viewed through the lens of cricket – the national game in both countries. This dissertation about a significant, yet overlooked, chapter in sporting history examines the Australian cricketers’ response to the social, racial and political hierarchies of lateecolonial India. The experience of the touring party encouraged a reeimagining of ideological perspectives and this thesis identifies a uniquely Australian subjectivity to the British colonisation of India. The tour between the colony (India) and the dominion (Australia) can be interpreted as an antie imperial gesture.

The life and times of Dr Hermann Beckler (1828-1914) : An Australian - Barvarian Odyssey
- Authors: Dodd, David

- Type: Text , Thesis , Masters
- Full Text:
- Description: The principal aim of this research thesis has been to reconstruct the life and times of Dr Hermann Beckler (1828-1914), a Bavarian-born scientist and adventurer who spent six years in Australia between 1856 and 1862. This study constitutes the first authoritative analysis of Beckler’s life. It focuses on the various turning points that influenced his odyssey-like journey from Bavaria to Australia and back again, as well as his travels within Australia, his interest in the natural environment and the botany of Australia, and his empathy towards the Indigenous people. Beckler was a product of the Age of Romanticism. He was an enigmatic and contemplative person, yet possessed a degree of toughness and resilience to overcome what appeared to be initially a self-imposed exile, replete with self-recriminations, as he tried to establish himself, firstly as a medical doctor and then as a pharmacist in the pioneering Moreton Bay region of colonial New South Wales. His interests in the natural sciences provided a solution to the problem of employment, and his botanical collecting skills ultimately gained him a position with Dr Ferdinand Mueller of the Melbourne Botanic Gardens. He worked as a botanical plant collector in northern New South Wales before his medical qualifications and botanical saw him appointed as medical doctor and botanist to the Victorian Exploring Expedition 1860-1861 led by Robert O’Hara Burke and William John Wills. Beckler recognized this appointment as an opportunity to explore the hitherto unknown parts of the interior of Australia and while he did his best to fulfill his role, he was frustrated by the mismanagement of the whole expedition by Burke’s erratic leadership and by the ineptitude of the Royal Society of Victoria’s Exploration Committee. He remains one of Australia’s and Germany’s forgotten explorer botanists. This thesis aims to bring to life Beckler’s contribution to this important episode in Australian colonial history.

The use of on-farm water points and artificial wildlife ponds in providing habitat for fauna in the Wimmera and Southern Mallee, Victoria, Australia
- Authors: Starks, Jonathan

- Type: Text , Thesis , Masters
- Full Text:
- Description: Fauna living in arid environments face strong ecological and physiological constraints. Water is the key requirement and vertebrates exhibit a range of adaptations for survival. Some species obtain water from their diet, but those which require water to drink or as habitat must either live in or near permanent water, or move in search of water. This strongly influences the distribution and abundance of vertebrate species in arid environments. In arid agricultural landscapes, the development of artificial water sources for stock has benefited water-dependant native fauna, particularly frogs. Little is known about the effects of removal of artificial water sources in these environments. In North-western Victoria, completion of the Northern Mallee Pipeline and the proposed construction of the Wimmera Mallee Pipeline will ultimately replace over 20,000 farm dams, resulting in the widespread loss of an open water resource currently used by fauna across the Wimmera and southern Mallee. The wildlife values of the different on-farm water points in the Northern Mallee Pipeline region and the remaining Wimmera Mallee Domestic and Stock Channel System were examined. Species richness and abundance of vertebrates were surveyed at farm dams, channels and stock troughs in open paddocks, and at farm dams in Mallee woodlands. Mallee woodlands with no available water were also surveyed. Sites were surveyed once per season to determine which species were utilising the different on-farm water points and Mallee woodlands. Knowledge of their usage by different species allowed the importance of each water point type to be determined and the impact of the closure of the channel system to be assessed. The study recorded 57 vertebrate species in the Northern Mallee Pipeline region, including six reptile, 43 bird, seven mammal and zero frog species. Surveys in the Wimmera Mallee Channel/dam region recorded 74 different species, including three reptile , 57 bird, eight mammal and six frog species. Overall species richness and abundance was highest at sites with a farm dam in a Mallee woodland, and the levels of species richness and abundance were significantly higher than at sites with Mallee woodland and no available water. The differences between the two site types were due mainly to greater abundance of water- dependant species at farm dams in Mallee woodland sites. For water points in open paddocks, species richness and abundance was highest at sites with a farm dam in an open paddock and lowest at sites with a stock trough in an open paddock. The difference between the different open paddock water point types were significant, and like woodland sites, were driven by greater numbers of water-dependant species. The study also examined whether purpose-built artificial wildlife ponds could provide habitat for water-dependant fauna and whether artificial wildlife ponds could potentially maintain fauna populations after de-commissioning of the existing channel system. The results of this study showed that artificial wildlife ponds placed in Mallee woodlands can provide habitat for birds, both in the Northern Mallee Pipeline region and the Wimmera Mallee Channel/dam region. The results also showed that these wildlife ponds can support species assemblages at levels comparable to a farm dam in a Mallee woodland, demonstrating that wildlife ponds can be effective in providing a degree of ‘replacement’ habitat for birds on farms. Frogs were not recorded using wildlife ponds situated in Mallee woodlands and this was considered due to the wildlife ponds being placed at least 900 metres from a nearby water source potentially too far for many frog species to disperse in an arid environment. Given these findings, the position of ponds was adjusted for the ponds installed in Black Box woodlands. Wildlife ponds in Black Box woodlands were also successful in providing habitat for birds and functioned as an important source of water for water-dependant birds in summer. Frogs were recorded using the wildlife ponds situated in Black Box woodlands and this was most likely due to their close proximity (<200 metres) to a nearby water source, as well as being located in a wetland-associated vegetation type. The success of the wildlife ponds concept has been demonstrated both in their ability to function as habitat for water-dependant fauna and through widespread community acceptance and support. With the de-commissioning of the channel and dam system removing open water sources from the farming landscape, artificial wildlife ponds installed on farms across the region could provide not just a vital habitat resource supporting water-dependant fauna, but in many areas, the only source of water for wildlife within the Wimmera and southern Mallee regions.

Video game classification in Australia : Does it enable parents to make informed game choices for their children
- Authors: Ross, Julie
- Date: 2016
- Type: Text , Thesis , PhD
- Full Text:
- Description: If Australian video game classification does not warn of all classifiable elements, parents may be making game choices that inadvertently expose their child to content that may be deemed inappropriate. Research shows that classification in the United States of America (USA) does not always warn of all elements, and to date there has been no comparable research in Australia. This research explored issues surrounding video game classification in Australia, and whether parents feel that provides enough information for them to make informed game choices, by asking the following questions: 1. Does video game classification in Australia provide enough information for parents to make informed decisions about what games their children play? 2. What are the factors that may prevent parents from protecting children from inappropriate content in video games? To answer the first question, a content analysis compared the classification given to video games classified ‘MA15+’ in Australia during the years 2009 - 2010 with their overseas counterparts. Results showed that a substantial number of video games in Australia carry different classification information than those overseas. To answer the second question, a mixed-methods questionnaire surveyed parents of children who played video games to explore issues surrounding video game classification, and the role it plays when making game choices for children. A quasi-longitudinal process within the questionnaire explored the effect that more detailed information has on game choices. Results showed that some parents use classification to assist them with choosing games for their child, but when presented with more information some parents will make different choices. Factors which may prevent parents from protecting their child from inappropriate content in video games were also identified. The Protection Motivation Theory underpinning this research was modified to produce the Vigilant Protection Motivation Theory. Overall, this research suggests that parents in Australia may not have enough information to make appropriate game choices.

Becoming "Brave and Gallant" : Decolonising the myths of Burke and Wills; Cross-cultural exchanges and the co-production of knowledge during the Victorian Exploring Expedition and the subsequent Relief Expeditions
- Authors: Jeffries, Peta
- Date: 2015
- Type: Text , Thesis , PhD
- Full Text:
- Description: The history of the Victorian Exploring Expedition (VEE), also known as ‘Burke and Wills’, has commonly been told as a story of ‘brave and gallant men’ who ventured into an unfamiliar landscape and became victims of the ‘ghastly blank’ interior of Australia. Visual artists and historians have memorialised these men as solo-hero explorers who sacrificed their youth and life potential for the sake of Australian nation. The myth of Burke and Wills is a constructed narrative and symbol of glory and achievement that denies the involvement of significant others in exploration and geographical knowledge creation. The path the VEE created through the centre of Australia opened up the broader continent for rapid colonisation and imperial expansion. The tragic legacy of the deaths of Burke and Wills is part of the Australian identity, however, some major aspects of the VEE successes and failures have been sidelined, silenced and even completely ignored in many historical accounts. The historical and visual art accounts that contributed to the memorialisation of Burke and Wills often denied the involvement of other exploration team members, the relief expeditions who went in search of the missing explorers, various intermediaries, guides, go-betweens and significantly Aboriginal peoples’ close involvement and or resistance to interior exploration. Yandruwandha people have been remembered as a friendly and accommodating community who assisted the explorers in their last days and who cared for John King. Within the archives and social memories are examples of agency, power, resistance, and varied perspectives of Burke and Wills. This ethnographic history asks why relations between the explorers, Aboriginal peoples and landscape have been told the way they have and provides examples of encounter and exchange, mutual adaptation and the co-production of knowledge as a way to decolonise the myths of Burke and Wills.

International students and social connectedness : The role sport can play

- Type: Text , Thesis , PhD
- Full Text:
- Description: Whilst it is well known that international education is a lucrative industry, what is not so well known is how to continue attracting prospective higher education students to Australia in what has become a competitive global market. Adding concern to Australia’s reputation as an international education provider is the recent research which indicated that international students are dissatisfied with their social experiences while in Australia. This research highlights that international students in Australia are not getting the most value out of their educational sojourn, in part, because of their less than engaging experiences with Australians. As a consequence, one of the main challenges faced by Australia’s international education sector is to create and sustain a positive student experience in order to enhance Australia’s reputation as an education provider, be fair to the students and remain competitive in this valuable industry. Developing stronger social connections appears to be an important factor for creating a positive international student experience, and a case can be made to consider the role of sport as a potential strategy for enhancing the international student experience. In particular, sports participation and spectatorship may be possible vectors for enhancing international students’ social connections with Australians because of the opportunity provided for personal interaction. To date, there is a relative lack of research that has investigated this relationship. This Australian-based study aimed to bridge this knowledge gap by focusing on three key areas: (1) to determine whether there was a relationship between sports participation and social connectedness, and if this relationship was influenced by the students’ type and level of sports participation; (2) to determine whether there was a relationship between sport spectatorship and social connectedness, and if the context of sport spectatorship influenced this relationship; and, (3) to determine whether there was a relationship between sport spectatorship and sports participation, particularly from the perspective of international students in Australia. ii The investigation used a mixed methods approach, which combined quantitative and qualitative data collection and analysis, in a sequential manner. The first phase involved the collection of questionnaire data. Subsequently, these quantitative findings were used to frame the qualitative interview themes and foci. Through this process, greater depth and personal perspectives were added to the initial findings to enrich understanding of various elements of the investigation. Qualitatively the overarching premise as to why a quantitative relationship existed between sports participation and social connectedness (p<0.0001) was that sporting involvement enabled close proximity to the Australian people, who the students perceived to be highly active in sport. The qualitative findings also supported the quantitative finding for the second research sub-question indicating that spectatorship was related to social connectedness (p<0.0001). According to the qualitative results spectatorship was deemed to be one of the best ways for students to connect with Australian people. The students explained this was possible because spectatorship provided them with an easy and relaxed way to connect to people, particularly Australian people and in a casual environment. Three underlying themes explained why spectatorship was perceived to provide this unique environment and connection opportunity. These were (1) spectatorship is a universal and inclusive leisure activity; (2) spectatorship connects people; and (3) Australia has a strong sporting culture. The quantitative results from the third research sub-question revealed a relationship between spectatorship and sports participation (p<0.0001) and the qualitative interview data enriched this finding. The interview data indicated that students considered spectatorship as a driver for their sports participation. Students revealed that spectatorship helped them increase their level of sports participation, and to feel included in sport even without physical involvement. The qualitative results from this study suggest spectatorship plays a more important role than sports participation for international students in developing social connections with Australian people. Results revealed that increased involvement in sports participation and spectatorship enhanced students’ understanding of the Australian language and culture, assisting them iii to develop and maintain meaningful friendships in their host country. This finding indicates that sport may be a unique way for international students to achieve the connections they desire with Australians. The value of both sports participation and spectatorship for international students is evident. Accordingly it is recommended that Australian educational institutions offer sporting opportunities specifically for international students, and thus contribute positively to a rewarding and lasting educational experience.

The effects of playing Nintendo Wii on depression, sense of belonging, social support, and mood among Australian aged care residents : A pilot study
- Authors: Chesler, Jessica
- Date: 2015
- Type: Text , Thesis , Masters
- Full Text:
- Description: Adults aged 65 years or older constitute the fastest growing age group worldwide, leading to greater numbers of people requiring care in residential facilities. Adults in these facilities have higher levels of depression, lower levels of social support, and lower levels of sense of belonging compared with older adults living in the community. Research has begun to assess the effectiveness of interventions aimed at improving the mental health of aged care residents. Within this population, cognitive and physical benefits of playing video games have been documented in the literature, as well as greater social interaction, and decreased loneliness. The aim of the current study was to investigate the effectiveness of playing Wii bowling twice weekly, with up to 3 other residents, for 6 weeks. An Australian sample of 31 women and 8 men between the ages of 65 and 95 years (Mean age = 85.68, SD = 9.62) were randomised to either a treatment or control group based on their place of residence. The residents completed demographic information, The Veterans Affairs Saint Louis University Mental Status Exam, the Geriatric Depression Scale Short Form, the Social Provisions Scale, and three visual analogue scales to measure sense of belonging and mood. These scales were completed pre-intervention (0 weeks), postintervention (6 weeks), and at 2-month follow up (14 weeks). Qualitative data on social interaction between group members was also collected at weeks 1, 3, and 6. Results did not support the use of the Wii to improve residents’ self-reported levels of depression, social support, sense of belonging, or mood. Social interaction increased over the 6 weeks, as measured by interaction analyses and also residents’ comments. Overall, findings indicate that Wii bowling may be a useful intervention as part of a comprehensive care program to increase social interaction within aged care. Pervasive environmental problems associated with aged care, as well as participant characteristics, may have reduced the effectiveness of the intervention program.

Overall, findings indicate that Wii bowling may be a useful intervention as part of a comprehensive care program to increase social interaction within aged care. Pervasive environmental problems associated with aged care, as well as participant characteristics, may have reduced the effectiveness of the intervention program.
