- Description: Blockchain (BCT) is an emerging technology that promises many benefits for organisations, such as disintermediation, data security, data transparency, a single version of the truth, and trust among trading partners. Despite its multiple benefits, the adoption rate of BCT among organisations has not reached a significantly high level worldwide. The present thesis addresses this issue in the Australian context. There is a knowledge gap in what specific factors, among the plethora of factors reported in the extant scholarly and commercial literature, affect Australian organisations while deciding to adopt BCT. To fill this gap, this thesis uses a mixed-methods approach known as sequential exploratory mixed methods. In this approach, the research starts with a qualitative phase as an initial phase followed by a quantitative phase. During the qualitative phase, data were collected through semi-structured interviews of the BCT experts and decision-makers working with the ifferent Australian organisations that adopted or were in the process of adopting BCT. The Technology, Organisation, Environment (TOE) framework, based on the qualitative interpretative approach, was used as a theoretical lens during the qualitative phase. The qualitative data were analyzed using the thematic analysis technique with the SQR NVivo software. The analysis shows that the different factors, belonging to the technological, organisational, and environmental contexts, affect the organisational decision to adopt BCT in Australia. The technological factors include perceived benefits, perceived computability, perceived complexity, perceived disintermediation, and perceived information transparency; organisational factors are organisational innovativeness, organisational learning capability, top management support; environmental factors consist of government support, standards uncertainty, competition intensity, and trading partners readiness. The qualitative analysis also shows the direct and moderating effect of the perceived risks between the relationship of the identified factors and organisational adoption of BCT. Based on the findings of the qualitative phase, the thesis develops a theoretical conceptual model, which shows the relationship between the factors and the organisational adoption of BCT. To increase the external validity of the developed conceptual model, the thesis started a quantitative phase with the administration of an online survey for data collection. Certain criteria were set to screen out the irrelevant participants in the survey. During this phase, hypotheses were proposed for the relationship of the factors identified in the qualitative phase and the organisational adoption of BCT. The survey data was analyzed using the PLS Structural Equation Modelling (SEM) technique with the SmartPLS 3 software. The quantitative analysis confirms the findings of the qualitative phase that the perceived benefits, perceived compatibility, perceived information transparency, perceived disintermediation, organisational innovativeness, organisational learning capability, top management support, competitive intensity, government support, and trading partner readiness have a positive effect on the organisational adoption of BCT. Whereas the perceived complexity, standards uncertainty, and perceived risks have a negative effect. The analysis also shows that the moderating effects of perceived risks are significant in the relationship of perceived compatibility, perceived information transparency, perceived disintermediation, organisational innovativeness, organisation innovativeness, competition intensity, and organisational adoption of BCT. Contrary to the qualitative findings, ‘perceived risks’ has no moderating effects on the relationship of perceived benefits, organisational learning capability, top management support, government support, trading partner readiness, and the adoption of BCT. The thesis has both theoretical and practical contributions, which are useful both for theory development and decision-making for the adoption of BCT in Australia. Theoretically, this thesis contributes to the existing IT adoption literature in several ways. Firstly, the thesis provides empirical evidence about the factors affecting organisational adoption of BCT in Australia. This is the first in-depth sequential exploratory mixed methods research that bridges this knowledge gap in the extant literature. The identification of such factors is important, particularly for the Australian government and organisations interested in the value creation of BCT. Second, the thesis reports the effect of new factors, namely, perceived information transparency, perceived disintermediation, organisational innovativeness, organisational learning capability, standards uncertainty, trading partner readiness, and competition intensity on BCT adoption that are exclusively identified in this research. Third, this thesis confirms the findings of the past studies that the factors of perceived benefits and perceived compatibility, perceived complexity, and top management support have an effect on the organisational adoption of BCT. Fourth, according to the best of the authors' knowledge, this is the first research that has used the qualitative interpretive research approach to investigate the organisational adoption of BCT. Therefore, the thesis confirms the suitability of the qualitative interpretive research approach for BCT adoption. Lastly, most of the researchers have used the TOE framework in either in qualitative or quantitative research. This thesis proves its validity in mixed methods research as well. The thesis's practical contributions are discussed in chapter 7.

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

- 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.

The intellectual life of Catherine Helen Spence
- Authors: McFarland, Michele
- Date: 2004
- Type: Text , Thesis , PhD
- Full Text:
- Description: This thesis will argue that Catherine Helen Spence, a writer, preacher and reformer who migrated from Scotland to Australia in 1839, performed the role of a public intellectual in Australia similar to that played by a number of women of letters in Victorian England. While her ideas were strongly influenced by important British and European nineteenth-century intellectual figures and movements, as well as by Enlightenment thought, her work also reflects the different socio-political, historical and cultural environment of Australia. These connections and influences can be seen in her engagement with what were some of the "big ideas" of the nineteenth century, including feminism, socialism, religious scepticism, utopianism and the value of progress. In arguing that Spence was a public intellectual, I will consider the ways in which she used the literary genres of fiction and journalism, as well as her sermons, to try to help her fellow citizens make sense of the world, attempting to organise and articulate some of the significant ideas affecting the political, social and cultural climates in which they lived. Through the exploration of Spence's intellectual work, I will show how she can be regarded as making a significant contribution to nineteenth-century Australian intellectual life, one that has been under-recognised and under-valued.

International students and social connectedness : The role sport can play

- 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.

Managed identities : How do Australian university students who stutter negotiate their studies?
- Authors: Meredith, Grant
- Date: 2019
- Type: Text , Thesis , PhD
- Full Text:
- Description: Previous social research focused on people who stutter has problematised and largely ignored the experiences of university students who stutter, relying heavily upon surveys of teachers and peers while almost ignoring the authentic voices of students who stutter. Using a novel bricolage approach incorporating autoethnography, this project posed the question: “How do students who stutter negotiate their university experiences in Australia?” In 2008, a unique, web-based audit of 39 Australian public universities concluded that little publicly accessible information about stuttering support services was available for prospective university students. In many ways, stuttering is absent from disability classifications and service systems in higher education. An online survey of 102 Australian university students who stutter, and follow-up individual interviews with 15 students, revealed how these students manage their social identities from enrolment through to graduation. Only a minority of students reported ever formally disclosing their functional impairment to university support services or academic staff. This meant they rejected and/or avoided the disability label and associated stigma. The students were found to exercise a high degree of individual agency and creativity throughout their university journey. Many employed ‘concessional bargaining’ techniques to effectively navigate the oral assessment requirements during their degrees. Analysis of the interview and survey data is interspersed with critical self-reflection by the author – as a university lecturer who himself stutters. This thesis makes a significant contribution to shaping our understanding of the social identities and trajectories of university students who stutter. These students have been recast as positive, purposeful, resourceful and creative agents whose actions can be largely understood from a social model of disability. A series of recommendations for supporting and teaching these students are made to key stakeholders in higher education.

A conceptual re-alignment of methodology underpinning tax effect accounting : An Australian exploration of the contemporary normalising effect
- Authors: Morton, Elizabeth
- Date: 2016
- 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 financial stress index to model and forecast financial stress in Australia
- Authors: Mukulu, Sandra
- Date: 2017
- Type: Text , Thesis , PhD
- Full Text:
- Description: The series of financial crises that cascaded through and rocked much of the world over the past decade created opportunities to draw meaning from the pattern of countries succumbing to crisis and those who appear to be wholly or partially immune. This thesis examines the case of Australia, a developed country that has seldom experienced an endogenous crisis in the last few decades, but has experienced crisis by contagion. This study designs a financial stress index to measure and forecast the health of the Australian economy and proposes a custom-made stress index to: Gauge the potential for a crisis; and Signal when a timely intervention may minimise fear and contagion losses in the Australian financial market. Financial and economic data is used to design indicators for stress in the banking sector and equity, currency and bond markets. Further, this study explores how movements in equity markets of key trading partners of Australia can be used to predict movements in the Australian equity market. The variance-equal weights (VEW) and principal components approach (PCA) are used to subsume 22 stress indicators into a composite stress index. The VEW and PCA stress indexes were examined to determine monitoring and their forecasting capabilities. It was found that the VEW stress index performed better than the PCA stress index, because it provided more consistent estimates for the level of Australian financial stress. Although, both models show some promise, each model fell short of giving adequate forecasts in financial stress especially at the peak time of the 2007-2009 GFC. Thus, more research is needed to understand the complex nature of financial crisis, how crises develop and the techniques that can be used to predict the onset of financial crises.

Further, this study explores how movements in equity markets of key trading partners of Australia can be used to predict movements in the Australian equity market. The variance-equal weights (VEW) and principal components approach (PCA) are used to subsume 22 stress indicators into a composite stress index. The VEW and PCA stress indexes were examined to determine monitoring and their forecasting capabilities. It was found that the VEW stress index performed better than the PCA stress index, because it provided more consistent estimates for the level of Australian financial stress. Although, both models show some promise, each model fell short of giving adequate forecasts in financial stress especially at the peak time of the 2007-2009 GFC. Thus, more research is needed to understand the complex nature of financial crisis, how crises develop and the techniques that can be used to predict the onset of financial crises.

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.

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.

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.

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. Both countries were attempting to forge relationships that would be independent from Britain. 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. It also provides a new understanding and historical counter narrative of idetwentieth century IndianeAustralian sporting history and cultural exchange.

Capital budgeting practices and firm performance : A comparative study of Australia and Sri Lanka

- Date: 2016
- Type: Text , Thesis , PhD
- Full Text:
- 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.

Avenue and Arch : Ballarat's commemoration. How are community attitudes to war and peace reflected in the civic management of the Avenue of Honour and the Arch of Victory?
- Authors: Roberts, Philip
- Date: 2018
- Type: Text , Thesis , PhD
- Full Text:
- Description: This thesis examines the importance of memory, commemoration, heritage and militarism in relation to Ballarat’s Avenue of Honour and Arch of Victory. Inspired by Ken Inglis and other historians who have analysed war commemoration, the thesis argues that, led by the Lucas clothing company, Ballarat civic leaders and community members commemorated the war service and sacrifice of local soldiers, airmen, sailors and nurses by planting the 22-kilometre Avenue during 1917–19 and by constructing the prominent Arch in 1920. Although Ballarat voted against conscription in 1916 and 1917 and was a ‘divided’ society, the Avenue and Arch were able to unite members of the local community. From the 1920s, through memory and mythology during the civic maintenance of the Avenue and Arch, Australian community attitudes to war and peace were reflected, and a determined effort was made to remember the service and sacrifice of military personnel for all Australian wars. Discussion of the need for peace remained in the background until recent years. Important influences on the civic management were the collective memory of the so-called Lucas Girls, a group of former female employees of the Lucas clothing company, and of the members of the Arch of Victory/Avenue of Honour Committee. Increasingly, the embracing of the Anzac legend and an emphasis on loss and grief was reflected in the civic management. By 2017 the Avenue and Arch were in pristine condition and, through the Garden of the Grieving Mother, had transformed to symbolise the importance of remembering the sacrifices and grief of war and the need for peace. The project was based on documentary research and oral history, using an examination of newspaper and other documentary accounts from 1917–2017, a study of Arch of Victory/Avenue of Honour Committee papers and conservation management plans, research of relevant books and articles, landscape fieldwork and interviews with 26 people.

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.

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.

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.

10 Days in 2009 : An auto-ethnographical study of "Communical Resistance" taken by international students in Australia

- Description: The early millennium saw the rise of an educational system in Australia where unchartered private educational provider institutions teach degree courses via contractual arrangements with parent universities. This study examines an incident where students at several such institutions collectively declined to submit a required online assessment piece to the possible detriment of the successful completion of their degrees. The research questions that arose from this incident were; what went wrong; how can we understand what happened here; and, what does this mean for me personally? Students’ perceptions of an online assessment piece are examined in the study of this incident. The study covers identical units offered at six private providers in three different Australian cities and the parent university. The students at the private institutions were all international students; those at the parent were a mix of international and domestic students. The assessment piece, a mandatory requirement for completion of the degree, was given to a collective cohort of approximately 400 students. The majority of students from four of the private institutions declined to submit the assessment piece. Initial research indicated that the students were uncomfortable with the format of a new blended-learning delivery introduced that year (2009). Upon deeper investigation, it was revealed that the declination to submit was, in fact, a complex situation involving conflicts, cultural clashes, social upheaval, and legislative misunderstandings that combined to create an environment where the students felt they had no option but to openly protest against perceived injustices. The author of this work is also the educator at the centre of this event, thus the thesis has been written in an auto-ethnographical method, viewed through the educator’s lens. To protect sensitive information, pseudonyms have been used and identifying details removed. The parent university at the centre of the event, named Newgarth University, is fictitious. Auto-ethnography has been used to present the empirical data (quantitative and qualitative), and the reader will be taken through a “detective story” that reveals various characters, plots, and protest. The study documents a previously unrecorded incident in the international student education industry in Australia. The study offers explanations as to why this incident occurred and adds to the cumulative knowledge of the international student education industry in Australia by offering suggestions to prevent such incidents occurring again. The study demonstrates that when a group of students are placed in an unfamiliar uncomfortable environment with little or no access to pastoral care or welfare services, they will create support groups of allegiance to protect their interests. These allegiance groups will employ tried and tested methods of communal resistance practised by the dominant culture of that field of endeavour.

The contribution of silverfish (insecta: zygentoma) to Australian invertebrate biodiversity and endemism
- Authors: Smith, Graeme
- Date: 2018
- Type: Text , Thesis , PhD
- Full Text:
- Description: Silverfish (Order Zygentoma) are quite abundant in Australia but have been largely overlooked. This thesis examines the biodiversity of the Australian fauna at the level of genus, describing at least one representative species from each named genus and some new genera. The endemism of the fauna is evaluated and likely zoogeographic origins proposed. Over 4000 specimens were examined, either collected by the author, borrowed from or examined within museum collections or supplied by organisations and individuals conducting fauna surveys. Twenty- seven new native species are described and two redescribed, bringing the number of named species recorded in Australia to 74. Five new genera are described and four additional genera recorded in Australia for the first time including autochthonous representatives of three subfamilies previously unrecognised as native to Australia (Acrotelsatinae, Lepismatinae and Coletiniinae). No representatives of the families Maindroniidae, Tricholepidiidae and Protrinemuridae were found. The subfamily Acrotelsatinae was redefined following a revision of the enigmatic genus Anisolepisma Paclt, 1967 with the unique structure of the thoracic sterna identified as diagnostic for the subfamily. Contrary to existing opinion, it is suggested that this is a fundamentally different and plesiomorphic character, rather than an apomorphic reduction of the free thoracic sterna. A monograph of the Australian Zygentoma is presented, including a summary of the biology of the order, a key to and diagnoses of the genera, as well as information on the known habitat and distribution of each genus and a discussion of their zoogeography. At the suprageneric level the fauna is less diverse than seen in other zoogeographic regions but appears to be rich in the number of species. The fauna displays a high degree of endemism with 91% of described species and 52% of the genera known only from Australia. Some genera appear to be ancient and probably represent a Pangean element in the Australian fauna. Others appear to have emerged in the late Jurassic when Africa was still joined to Gondwana, while some may have appeared in the Cretaceous or Palaeocene when Australia and South America were connected to Gondwana. More recent links with the Asian fauna are limited and there appears to be no widespread highly mobile global species other than the six introduced anthropophilic species. Maps of the worldwide distribution records extracted from the taxonomic literature are used to discuss the zoogeography of the subfamilies and tribes present in Australia. Molecular data using two mitochondrial genes (16S and COI) as well as a nuclear gene (28S) were compared with detailed morphological and morphometric analysis to examine populations initially determined as Heterolepisma sclerophylla or close to it. Distances of 0.9– 1.8% or greater in 28S, and 7.2–14% in COI were associated with morphologically distinct species. A southern Queensland population was found to be genetically, morphometrically and morphologically very distinct from those collected in NSW and was described as new (Heterolepisma sp. B). Six well-defined barcode clusters (“lineages”) were identified within the NSW populations, each with >4% divergence in COI sequences and each geographically restricted. Intracluster divergences are also large, and despite the well-supported phylogeny no clear “barcode gap” (distinction between intracluster and intercluster distances) was found for three of the six NSW populations. The 28S data distinguished only four of the six COI clusters from NSW with essentially no variation within each cluster. The 28S data generally aligned well with morphological evidence, clearly identifying Heterolepisma sp. B as a distinct species, and supporting also the description of Heterolepisma sp. A even though it only appears to differ from H. sclerophylla in the number of styli. Similar genetic distances are observed in 28S data for H. sclerophylla populations from North Nowra, Glenbrook/Burralow/Nattai and Megalong, however the Broulee and Wellington populations have identical 28S sequences. The low levels of variation in 28S sequences between NSW populations accord with the lack of unambiguous morphological differences.

Stock market predictions based on quantified intermarket influences
- Authors: Tilakaratne, Chandima
- Date: 2007
- Type: Text , Thesis , PhD
- Full Text:
- Description: This research investigated the feasibility and capability of neural network-based approaches for predicting the direction of the Australian Stock market index (the target market). It includes several aspects: univariate feature selection from the historical time series of the target market, inter-market analysis for finding the most relevant influential markets, investigations of the effect of time cycles on the target market and the discovery of the optimal neural network architectures. Previous research on US stock markets and other international markets have shown that the neural network approach is one of most powerful techniques for predicting stock market behaviour. Neural networks are capable of capturing the non-linear stochastic and chaotic patterns in the stock market time series data. This study discovered that the relative return series of the Open, High, Low and Close prices of the target market, show 6-day cycles during the studied period of about 14 years. Multi-layer feedforward neural networks trained with a backpropagation algorithm were used for the experiments. Two major testing methods: testing with randomly selected test data and forward testing, were examined and compared. The best neural network developed in this study has achieved 87%, 81% 83% and 81% accuracy respectively in predicting the next-day direction of the relative return of the Open, High, Low and Close prices of the target market. The architecture of this network consists of 33 input features, one hidden layer with 3 neurons and 4 output neurons. The best input features set includes the relative returns from 1 to 6 days in the past of the Open, High, Low and Close prices of the target market, the day of the week, and the previous day’s relative return of the Close prices of the US S&P 500 Index, US Dow Jones Industrial Average Index, US Gold/Silver Index, and the US Oil Index.
