I hope that I have got some art

  • Authors: Calderone, Ursula
  • Date: 2008
  • Type: Text , Thesis , Masters
  • Full Text:
  • Description: In this thesis I have researched what I believe is the powerful, catalytic effect of poetry on the creative work of some artists. I have chosen three, Australian painters; Sidney Nolan, James Gleeson and Brett Whiteley. I have looked carefully at how the works of various poets have influenced and inspired these artists. I have put forward the idea that this engagement with the poetic realm has greatly enhanced the artist’s creative form-making. Indeed these artists have acknowledged their strong links with the world of poetry. I have touched very briefly on the ideas of some renowned philosophers who stress society’s need for fine works of art. In my opinion great works of art can come from this linking of painting with poetry and therefore, this nexus is to be encouraged. I have in my own painterly works looked to the poets for inspiration. In The Wimmera Series of landscape works, I read Brian Edwards’ and Homer Reith’s poetry, and found in their imagery a rich source of creative ideas. I continued to read the works of the poets and found that the poetry of Ezra Pound, Dante Alighieri, Judith Wright and the works of many others, were an inspirational and catalytic force. I have also discovered on this artistic journey that the very writing of poetry, my own attempts in this field, seemed to bring to my painting, a sharper, a more analytical and critical focus. Renowned art critics and art historians have criticised contemporary art for its lack of the poetic, and its boring shallowness. I would urge artists to engage with the poetic realm, and this interplay between painting and poetry, may produce fine works of lasting greatness.

  • Description: The purpose of this research is to contribute a non indigenous perspective to current discourse on sense of place in contemporary Australia. The research employs a number of strategies to investigate current responses to our geographic and historical time position. Within the exegesis there is a vers libre poem, written from the imagined viewpoint of members of the Burke and Wills’ expedition. The poem is supported by a superimposition of the Don Quixote story over that of the ill-fated inland Australian explorers. [...]

Leadership and career aspirations in female and male middle managers : A cross-cultural study in Malaysia and Australia

  • Authors: Jogulu, Uma
  • Date: 2008
  • Type: Text , Thesis , PhD
  • Full Text:
  • Description: Western research dominates in areas of theories and models which describe organisational behaviours, human resource management and workplace participation. However the 21st century brings new challenges. Findings to-date suggest that attitudes and values are strongly culture specific therefore many facets now require re-thinking by human resource specialists and organisational behavioural theorists. For instance, the globalisation of the market economy has dramatically changed the contemporary business environment. As a direct consequence of the globalisation process, the nature of organisational structures and workforce diversity has also changed. Such changes may make the application of Western theories less relevant to explain behaviours and attitudes of contemporary employees around the world. Therefore, there is a need for expanding our cross-cultural understanding in order to provide practical knowledge to enhance people and business management so that organisations can remain successful nationally and internationally. Comparative cross-cultural studies are required to expand on Western theories and models. The present study acknowledged and regarded the importance of cross-cultural studies to date, and endeavoured to expand on the extant knowledge by providing specific information relating to two diverse countries. The aim of the research project is to examine two measurable areas of organisational behaviours namely leadership styles and managerial career aspirations of female and male managers in Malaysia and Australia to explore the similarities and differences between the groups. The study found differences within and between female and male managers in Malaysia and Australia in terms of leadership styles, perception of effectiveness, perceptions towards managerial career aspirations and perceived promotion opportunities during the quantitative and qualitative data collection stages. The study concludes by providing empirical evidence to refute the universality of Western theories and models in all cultures. The analysis of both quantitative and qualitative data revealed significant differences in terms of values, behaviours and attitudes of managers in the two diverse cultures which have important implications for work and employment. This suggests that Western theories and models of organisational behaviour and workplace participation are not universally applicable, appropriate or relevant in all cultural environments. Implications for theory and practice in the light of an enhanced cross-cultural understanding were recommended.

Reaching the heart : Assessing & nurturing spiritual well-being via education

  • Authors: Fisher, John
  • Date: 2008
  • Type: Text , Thesis , EdD
  • Full Text:
  • Description: Several quantitative measures of spiritual well-being were developed with primary and secondary school students and teachers, and university education students, namely the Spiritual Health And Life-Orientation Measure, Feeling Good, Living Life, and the Quality Of Life Influences Survey. Spiritual dissonance was revealed by comparing respondents’ ‘ideals’ with ‘lived experiences’ in four domains of spiritual well-being. Teachers and university education students reported a decline in help being provided in schools to develop the relationships which foster school students’ spiritual well-being.

Reflective space : A personal journey towards a re-envisioning of the Australian landscape

  • Authors: Donald, Colin
  • Date: 2008
  • Type: Text , Thesis , PhD
  • Full Text:
  • Description: Whilst the notion of the ‘Reflective Space’ could arguably encompass many conceptual positions and propositions, for the purposes of this research investigation the ‘Reflective Space’ referred to in the title of this exegesis will focus upon what I consider as an emerging and growing consciousness of the natural world. As a theoretical and conceptual construct, the investigation considers how this growing consciousness can be seen to be expressed through the medium of representations of the Australian landscape. This work considers a number of contemporary theoretical positions and a number of relevant social and political questions; it also acknowledges that within such spheres of reflection, the issue of being sustainable in relation to our interactions and perceptions of this natural world looms as perhaps one of the most pressing of our time. While it will be acknowledged that the depiction of landscape enjoys a long-standing tradition within the Australian cultural mind, the suggestion will be made that certain aspects of these visualisations can be seen to be ‘reflective’ of a visual, cultural and physical degradation, and indeed even an apprehension of the physical ‘space’ that is represented as landscape. The investigation considers and reflects upon what can be observed as contentious and ambivalent attitudes expressed towards landscape perceived through works of art. Strategies for adopting a perceptual visual ethic grounded within the concepts and principles of sustainability will be presented for consideration. By applying such modes of interpretation to perceptions of land and landscape depiction, new appreciations for the cultural ‘space’ that is landscape will be developed. Such understandings will consider and reflect upon the temporal nature of our natural world. The thesis is this: that to be able to think and act in a sustainable fashion in relation to our environment, our perceptions and interpretations of visualisations of landscape must include a recognition that the land is a ‘temporal’ space, in which past and possible futures are immanent in the present.

Ship of Fools

  • Authors: Collins, Julie
  • Date: 2008
  • Type: Text , Thesis , Masters
  • Full Text:
  • Description: The Ship of Fools is an ancient allegory that has long been a part of Western culture in literature, art and song... It has been chosen by many to comment on contemporary issues throughout history, highlighting the foibles of that society. The ship of fools however is also about our world, as a vessel, full of passengers of humanity, full of those who have no care what they do or where they are going... It is the 21st Century and we are all sailing on a Ship of Fools. We consume beyond reason, we want, and get the latest, newest, biggest things. We complain about interest rates and petrol prices, but consume beyond reason often with purchases on credit we don't really need.

The determinants of capital structure in Chinese listed companies

  • Authors: Shen, Gensheng
  • Date: 2008
  • Type: Text , Thesis , PhD
  • Full Text:
  • Description: Traditional financial theories see capital structure as a result of mainly financial, tax and growth factors (Modigliani & Miller, 1958). But corporate governance theories (Jensen & Meckling, 1976) and business strategy theories (Barton & Gordon, 1988) suggest that ownership structure and ownership concentration, product diversification and asset specificity may also influence capital structure. Focusing on the examination of the determinants of capital structure in Chinese listed companies, this research goes beyond financial factors and considered business strategy and corporate governance approaches, and their impact on capital structure, in a transitioning Chinese context where institutions, expertise and regulatory processes are different to, but converging on, Western approaches. A panel data set of 1,098 Chinese listed companies for the period of 1991 to 2000 was collected from published sources, and conventional and innovative econometric methodologies were used to model a range of relationships between capital structure and its financial and non-financial determinants. The statistical approaches used in this study included Ordinary Least Squares Model and also Linear Mixed Model, which is a powerful tool to examine panel data where independence of explanatory variables is not assumed. The analysis also involved Hox’s model building procedures to measure model fit. The capital structure of listed companies in both the Shenzhen Stock Exchange and the Shanghai Securities Exchange is positively related to a firm’s tax rate, growth and capital intensity and negatively related to a firm’s profit and size. Other financial factors such as tangibility, risk and duration are non-significant. The capital structure of listed companies, particularly in the Shenzhen Stock Exchange, is positively related to product diversification and negatively related to asset specificity. The capital structure of listed companies in the Shanghai Securities Exchange is positively related to government ownership and ownership concentration of the largest shareholder and negatively related to legal person ownership and ownership concentration of the ten largest shareholders. The data and modelling support financial and non-financial determinants of capital structure. In particular, information asymmetry, business diversity and asset specificity have a significant impact on capital structure. In addition the empirical work in the study supports agency cost explanations of debt and equity. Finally the research demonstrates that the two main financial markets in China, Shenzhen and Shanghai, have operated differently but are converging towards a common norm. The research contributes to the general field of capital structure and provides valuable insights into the nature of the Chinese firm and the evolution of the Chinese financial system.

The role of an ICT change agent in ICT diffusion within technology projects in public and private sector setting

  • Authors: Jagodic, Jana
  • Date: 2008
  • Type: Text , Thesis , DBA
  • Full Text:
  • Description: Rapid changes in the competitive environment and increasing customer demands drive the public and private sectors to innovate by continually investing millions of dollars in Information and Communication Technology (ICT) projects. Basically, organisations depend on ICT technology for every part of their business. Companies are not only challenged to apply new technologies to remain competitive, they also need to spread (diffuse), manage and implement technological innovation across extended organisational boundaries. Diffusion, management and implementation of ICT innovation involve a considerable amount of risk and potentially protracted delays of technological projects. As a consequence of high demand for ICT innovation, as well as the risk of failure, a wide range of organisations such as state agencies and banks now employ so-called change agents to diffuse, manage and implement innovation within technological projects. While a large number of academics and practitioners are concerned with change agents who alter organisational culture, structure and processes, relatively little research has been undertaken on the role of ICT change agents in the innovation process. Thus, this professional doctorate study aims to fill that gap by exploring ICT change agents’ project work experiences within state agencies and banks and fuse them with theory. The research is based on case study methodology, including 41 cases within 12 target organisations in Australia and Germany. As a former ICT change agent, the researcher of this Doctor of Business Administration (DBA) study applied mixed research methods, also incorporating her ICT project experiences by using an individual reflection model. From this investigation emerged that change agents’ roles are embedded in components (organisational structure, project stages) and processes (ICT diffusion, informal networks). These findings underpin the model of ICT change agents who perform the multiple linker roles of these components and processes in order to deliver set project outcomes. The model is designed to inform practice by providing guidance for advanced ICT change agents’ training in public and private sector settings.

Unsupervised color image segmentation using Markov Random Fields Model

  • Authors: Islam, Mofakharul
  • Date: 2008
  • Type: Text , Thesis , Masters
  • Full Text:
  • Description: We propose a novel approach to investigate and implement unsupervised segmentation of color images particularly natural color images. The aim is to devise a robust unsu- pervised segmentation approach that can segment a color textured image accurately. Here, the color and texture information of each individual pixel along with the pixel's spatial relationship within its neighborhood have been considered for producing precise segmentation of color images. Precise segmentation of images has tremendous potential in various application domains like bioinformatics, forensics, security and surveillance, the mining and material industry and medical imaging where subtle information related to color and texture is required to analyze an image accurately. We intend to implement a robust unsupervised segmentation approach for color im- ages using a newly developed multidimensional spatially variant ¯nite mixture model (MSVFMM) using a Markov Random Fields (MRF) model for improving the over- all accuracy in segmentation and Haar wavelet transform for increasing the texture sensitivity of the proposed approach.

  • Description: For over seven years I have worked within the Disability sector witnessing not only the daily challenges faced by individuals with a disability, but also the barriers placed by society. Throughout this period I have become acutely aware of the lack of representation of individuals with Down syndrome within the public domain of contemporary art. This is an area which I believe also creates barriers to society's acceptance and understanding of disability.

Very low frequency - Magnetic spatial position detection range and map

  • Authors: Poplawski, Jaroslaw
  • Date: 2008
  • Type: Text , Thesis , PhD
  • Full Text: false
  • Description: Automated positioning systems designed to measure three-dimensional locations of objects are of paramount importance to flexible manufacturing applications. These systems should perform in an industrial environment, withstanding obstacles of solid objects and must be immune from external influences including changes in atmospheric conditions and surrounding noise. Automated positioning systems should also be free of mechanical contact and able to perform without having to establish a line-of-sight with the measured object. In this thesis, a novel design is proposed for the spatial measurement of the six degrees of freedom industrial robots and autonomous vehicles. Not only does the proposed system comply with the above characteristics, but it is also capable of achieving better resolutions than CCD cameras, easier to implement, safer than laser devices and more accurate than ultrasound systems.[...]

Where the sun has fallen to earth : A studio investigation of the nature of place, and the place of nature in visual art practice

  • Authors: Bennett, Julie
  • Date: 2008
  • Type: Text , Thesis , Masters
  • Full Text:
  • Description: My work involves the insertion of a structure into a landscape - a particular landscape, one I have contemplated for many years. In my landscape, 'my place', time is seen through the change of farming and weather seasons. We think we know and understand the landscape that immediately surrounds us, the place in which we live, but in the event of even a small change within that familiar place, our understanding and perceptions are called into question and our sense of time and space are rearranged.

A public want and a public duty [manuscript] : The role of the Mechanics' Institute in the cultural, social and educational development of Ballarat from 1851 to 1880

  • Authors: Hazelwood, Jennifer
  • Date: 2007
  • Type: Text , Thesis , PhD
  • Full Text:
  • Description: Mechanics’ Institutes were an integral element of the nineteenth-century British adult education movement, which was itself part of an on-going radicalisation of the working class. Such was the popularity of Mechanics’ Institutes, and so reflective of contemporary British cultural philosophy, that they were copied throughout the British Empire. The Ballaarat Mechanics’ Institute, established in 1859, instilled a powerful, male-gendered British middle-class influence over the cultural, social and educational development of the Ballarat city. The focus of this study is to identify and analyse the significance of the contribution made by the Ballaarat Mechanics’ Institute to the evolving cultural development of the wider Ballarat community, with a particular emphasis on the gender and class dimensions of this influence. This is done within the context of debates about ‘radical fragments’ and ‘egalitarianism’. Utilizing a methodology based on an extensive review of archival records, contemporary newspapers held at the Ballaarat Mechanics’ Institute, and previously published research, this study was able to show that, during the period from its inception in 1859 to 1880, the Institute became a focal point for numerous cultural, social and educational activities. As one of the few institutions open to all classes, it was in a position to provide a significant influence over the developing culture of the Ballarat community. The study has also identified the use made of the Institute’s School of Design by women and the contribution of these educational classes to preparing women for employment outside their traditional roles of wives and mothers. The thesis argues that despite some early radical elements, the Ballaarat Mechanics’ Institute initially espoused liberal egalitarian values. By 1880, however, the Institute was more readily identifiable as reflecting British, male, middle-class values.

DSM-IV AD/HD symptoms: Prevalence, gender and age differences, and construct validity of parent and teacher ratings of Malaysian children

  • Authors: Hafetz, Nina
  • Date: 2007
  • Type: Text , Thesis , PhD
  • Full Text:
  • Description: Attention-deficit/hyperactivity disorder (AD/HD) is marked by deficits in attention, hyperactivity and impulsivity (American Psychiatric Association, 1994). The current DSM-IV conceptualisation of AD/HD as comprising of separate, but related, Inattention (IA) and Hyperactivity/Impulsivity (H/I) dimensions have been supported in confirmatory factor analytic (CFA) studies. Despite being one of the most extensively studied childhood disorder, there is a lack of research on AD/HD in non-western populations. Research on AD/HD in Asian countries, particularly, is limited. To date, no study has comprehensively investigated the characteristics of AD/HD in a Malaysian sample. The current study had 4 major aims. The first aim of the study was to investigate how the IA and H/I symptoms groups vary by age, gender, and age by gender interaction. The second aim of the study was to obtain prevalence rates of DSM-IV AD/HD and the three subtypes (i.e., Predominantly Inattentive Type, AD/HD-IA; Predominantly Hyperactive/Impulsive Type, AD/HD-H/I; and Combined Type, AD/HD-C) within this population. This was examined for boys and girls separately, and together. The third aim of the study was to investigate the internal validity of DSM-IV AD/HD using single source confirmatory factor analysis (CFA), while the fourth aim of the study was to examine trait, source and error variance of the AD/HD symptoms using the CFA multitrait (IA and H/I) by multisource (parent and teacher) approach (CFA MT-MS). All the CFA and CFA MT-MS analyses were conducted separately for boys and girls and used scores recoded via the binary method, as opposed to the ordinal scoring method. The sample consisted of 934 Malaysian schoolchildren aged 6-12 years (436 boys: mean age 8.86 years; and 498 girls: mean age 9.02 years) [...] There was more source than trait variance for parent rated H/I and teacher rated IA for girls. Unique to the current study is the use of binary as opposed to ordinal data to run the CFA and MTMS analysis. The implications of the findings for the conceptualisation, assessment, treatment, psychometric properties of AD/HD rating scales and the recognition of AD/HD in the Malaysian population are discussed. Suggestions for future research are offered.
