- 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.

Conducting suicide research in Australia in relation to the operation of Human Research Ethics Committees
- Authors: Macgill, Jennifer
- Date: 2008
- Type: Text , Thesis , PhD
- Full Text:
- Description: This thesis began with a research project on suicide that was abandoned after many hurdles were encountered in terms of reaching participants and after various applications to ethics committees. The ultimate research question was then recast as ‘Do Human Research Ethics Committees influence the conduct of suicide research in Australia?’ The conceptual framework for setting up the research was derived from literature on Critical Theory, Feminism and Weberian concepts of power and rationality. Subsidiary questions were then derived from this literature and the starting exemplar case of my own research attempts. These considered whether suicide research was problematic for ethics committees, the nature of the experiences of ethics committee members in making decisions regarding suicide research and whether the influences of disciplinary background, patriarchal medical dominance and pro-positivism were evident. In addition, questions were raised about whether and how other researchers who sought approval to conduct research into suicide-related issues were appraised. [...]

Effects of commuting status upon community involvement of professionals in rural North West Victoria
- Authors: Devers, Deanna
- Date: 2006
- Type: Text , Thesis , PhD
- Full Text:
- Description: Because mobility is associated with rural social decline, this two-phase cross sectional study investigates whether social patterns in small, rural Australian towns are affected by commuting. Quantitative data, which was gathered via a mail-out questionnaire (response = 54 per cent) that was issued to 1,040 occupationally diverse professionals who worked in fourteen towns throughout north-western Victoria, was analysed to determine whether commuting and non-commuting professionals differed significantly in their community involvement. To explain why certain relationships emerged from survey analysis, face-toface interviews were subsequently undertaken with 24 questionnaire respondents. The key finding of this study is that there is a significant relationship between commuting status and the retention of rural professionals. A significantly greater proportion of noncommuters than commuters remain working in the one location for longer than five years. This finding has important implications for the sustainability of rural areas.

Exploring risk-awareness as a cultural approach to safety : An ethnographic study of a contract maintenance environment
- Authors: Borys, David
- Date: 2007
- Type: Text , Thesis , PhD
- Full Text:
- Description: Safety culture has risen to prominence over the past two decades as a means by which organisations may enhance their safety performance. Safety culture may be conceptualised as an interpretive device that mediates between organisational safety rhetoric and safety programs on the one hand, and local workplace cultures on the other. More recently, risk-awareness has emerged as a cultural approach to safety. Front line workers are encouraged to become risk-aware through programs designed to prompt them to undertake mental or informal risk assessments before commencing work. The problem is that risk-awareness programs have not been the subject of systematic research and the impact of these programs on the culture of safety and the resultant level of risk is unknown. Therefore, this ethnographic study of two sites within a large contract maintenance organisation in Australia explored what impact risk-awareness programs have upon the culture of safety and the resultant level of risk. The researcher spent two months in the field and data was collected through participant observation, semistructured interviews and through a review of organisational documents. This study found that managers focused upon collecting the paperwork associated with the program as proof that workers had a safer workplace, whereas workers preferred to rely upon their common sense rather than the paperwork to keep them safe. As a consequence, the riskawareness program resulted in a culture of paperwork and varying levels of risk reduction because the paperwork associated with the program created an illusion of safety for managers as much as common sense did for workers. The results of this study have implications for safety culture, risk-awareness programs and for organisational learning. They also have implications for organisations wishing to improve their safety culture by encouraging risk-awareness in front-line workers.

Progress in Australia over the 20th century : the ups, downs and reversals that occurred in Australian human wellbeing over the 20th century
- Authors: Gathercole, Michael
- Date: 2005
- Type: Text , Thesis , PhD
- Full Text:
- Description: "This study is an investigation of progress in Australia over the 20th century. Progress is defined here as the enhancement of human wellbeing. For the purposes of this study, human wellbeing will be characterised by five main components: knowledge, environment, economy, individual and social. Enhancement refers to positive directional change in terms of these components. The study firstly develops a framework to conceptualise progress. It then collects and uses statistical data in a descriptive study of what happened in Australia, over those 100 years, in terms of progress in general and in terms of its components. The study also develops a typology of relationships for models of progress, which best explain the Australian data. This study finally explores some of the relationships between the elements that make up the components of progress and looks at ways to best explain what has happened..." --p.1.

- Type: Text , Thesis , PhD
- Full Text:
- Description: "This thesis examines the paths by which four Celtic ethnic identities, Cornish, Welsh, Scottish and Irish, responded to the specific society and culture of the Victorian goldfields between 1850-1901. The individual Celtic groups intersected, harmonised and contested with each other in a process through which they retained their identities and yet managed to move towards becoming part of a larger, more-encompassing unity."

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.

The landscape of my life
- Authors: Woodfield, Linda
- Date: 2007
- Type: Text , Thesis , Masters
- Full Text:
- Description: The investigations surrounding the topic ‘The Landscape of My Life’ questions whether it is possible for a landscape to delineate the way in which we live our lives. For a period of thirty-two years my home has been a historic rural property comprising a dwelling and outbuildings on twenty acres of undulating countryside at Carngham. The work conveys the story of my life at this locale and pursues the motives behind the purchase of the country property, the experiences and remembrances that exist from this period of time and reflects upon the implications of a way of life over the last three decades. While considering the impact that a landscape can have on individual lives, it became important to consolidate the insights that surfaced for me with respect to my own life and works and compare it with that of other selected landscape artists. This comparison took into account personal and family backgrounds, artistic techniques, relationships with the land and the motivations that resulted in the depiction of particular landscapes. The result of these observations led to a consideration that not only can a landscape define the way in which we live our lives but, also identifies an affinity between human beings and the environment.

Web based regional newspapers : The role of content : A thesis
- Authors: Knox, Ian
- Date: 2002
- Type: Text , Thesis , Masters
- Full Text:
- Description: The phenomenon and acceptance of electronic publishing has proliferated in the last five years due to the expansion in the use of the World Wide Web in the general community. The initial fears that newspapers would be decimated by the introduction of this technology have been proven groundless, but despite a high web presence by newspapers world wide, profitable models of cyber papers are elusive. In an online environment traditional relationships between newspaper advertising and editorial may not stand. Despite the considerable body of published literature concerning the movement of print newspapers to an online environment, little was found concerning online content. A need to re-evaluate what content and functions are considered to be desirable by print readers, in an online environment was identified as the main objective of this research. Evaluation the of user attitudes to web based newspapers provides a foundation for future research into areas such as developing effective models for profitable online newspapers. To achieve this objective, the research tools used were a content analysis, an online newspaper user survey and newspaper management personal interviews. The study looked at Victorian regional daily newspapers that also had online versions. By focussing on the regional newspapers, meaningful comparisons could be made between content, staff attitudes and readership interests. The content analysis measured the quantum and nature of the content of the print and online versions of the regional dailies during a one week period. This provided a measure of the type and source of the articles included both in print and online. Newspaper editorial staff interviews contributed a personalised view of content priorities, which was then contrasted with a web based questionnaire which measured user requirements in relation to content and interactivity. It was found from the survey that content alone would not provide a sufficient basis to build a profitable online regional newspaper site. The findings were analysed in relation to the literature, newspaper site content and editorial staff interviews. Despite regularly accessing online newspaper sites, it was found that users are unwilling to pay for the experience. Users indicated a desire for a higher level of interactivity, in addition to the content, which is currently provided, by online regional newspapers. Evaluation of user attitudes to web based newspapers provides a foundation for future research into the development of effective for profitable online newspapers.
