- 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.

- 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.

- 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.

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.

Exploring risk-awareness as a cultural approach to safety : An ethnographic study of a contract maintenance environment

- 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.

Optimal number and placement of network infrastructure in wireless networks

- Description: Wireless Local Area Networks (WLANs) have become a major success in telecommunications during the last few years, due to advantages such as mobility, flexibility, and easier maintenance. A device called an access point (AP) acts as a base station in WLAN for connecting a group of users to the network via radio signal. During the planning of such a network an important problem is to determine the optimal number of these devices and their placement/distribution so that coverage, capacity, and physical security are maximised at minimum cost. In this thesis we are using continuous optimisation techniques to optimise the number of APs and their distribution while cost of deployment is reduced and physical security of the network is enhanced. To find the number and placement of APs, we developed a multi-objective functions model based on path losses and power for free space environments. The two functions in the models are combined by using a balancing parameter. Since it is recognised that some of the objectives can be handled one at a time, in another approach, we followed a step-by-step procedure. We start with a novel optimisation model based on path losses for indoor environments including obstacles. Cost of deployment is saved by finding the minimum number of APs ensuring that the path loss at each test point/receiver is below the given maximum path loss. Next, the physical security of the network is enhanced by placing the APs far from places accessible to unauthorised users to reduce the risk of intrusion into the network. This is achieved in the framework of the model by introducing potential unauthorised users in unauthorised areas for whom coverage is minimised. Due to the presence of obstacles in indoor buildings, the path loss function is discontinuous. Therefore, the objective functions are very complicated and most of the existing optimisation algorithms cannot be applied to solve the problem. We use a global optimisation algorithm that is not used by other researchers to solve the same problem. To validate the accuracy of the optimisation model and performance of the numerical methods, we run tests on several indoor buildings and use wide range of WLAN parameters. The results demonstrate the quality of our model and algorithm. Based on the proposed model and algorithm, we developed a software to assist the network designers in planning wireless LANs.

- Description: Doctor of Philosophy
- Description: Bioinformatics and computational biology are relatively new areas that involve the use of different techniques including computer science, informatics, biochemistry, applied math and etc., to solve biological problems. In recent years the development of new molecular genetics technologies, such as DNA microarrays led to the simultaneous measurement of expression levels of thousands and even tens of thousands of genes. Microarray gene expression technology has facilitated the study of genomic structure and investigation of biological systems. Numerical output of this technology is shown as microarray gene expression data sets. These data sets contain a very large number of genes and a relatively small number of samples and their precise analysis requires a robust and suitable computer software. Due to this, only a few existing algorithms are applicable to them, so more efficient methods for solving clustering, gene selection and classification problems of gene expression data sets are required and those methods need to be computationally applicable and less expensive. The aim of this thesis is to develop new algorithms for solving clustering, gene selection and data classification problems on gene expression data sets. Clustering in gene expression data sets is a challenging problem. The increasing use of DNA microarray-based tumour gene expression profiles for cancer diagnosis requires more efficient methods to solve clustering problems of these profiles. Different algorithms for clustering of genes have been proposed, however few algorithms can be applied to the clustering of samples. k-means algorithm, among very few clustering algorithms is applicable to microarray gene expression data sets, however these are not efficient for solving clustering problems when the number of genes is thousands and this algorithm is very sensitive to the choice of a starting point. Additionally, when the number of clusters is relatively large, this algorithm gives local minima which can differ significantly from the global solution. Over the last several years different approaches have been proposed to improve global ii Abstract Abstract search properties of k-means algorithm. One of them is the global k-means algorithm, however this algorithm is not efficient when data are sparse. In this thesis we developed a new version of the global k-means algorithm, the modified global k-means algorithm which is effective for solving clustering problems in gene expression data sets. In a microarray gene expression data set, in many cases only a small fraction of genes are informative whereas most of them are non-informative and make noise. Therefore the development of gene selection algorithms that allow us to remove as many non-informative genes as possible is very important. In this thesis we developed a new overlapping gene selection algorithm. This algorithm is based on calculating overlaps of different genes. It considerably reduces the number of genes and is efficient in finding a subset of informative genes. Over the last decade different approaches have been proposed to solve supervised data classification problems in gene expression data sets. In this thesis we developed a new approach which is based on the so-called max-min separability and is compared with the other approaches. The max-min separability algorithm is an equivalent of piecewise linear separability. An incremental algorithm is presented to compute piecewise linear functions separating two sets. This algorithm is applied along with a special gene selection algorithm. In this thesis, all new algorithms have been tested on 10 publicly available gene expression data sets and our numerical results demonstrate the efficiency of the new algorithms that were developed in the framework of this research

- Description: The Seven Valleys is an interactive 3D installation based artwork inspired by mystical writings of the Bahá'í Faith. Created as a modification of the firstperson shooter Unreal Tournament 2003 (Epic, 2003) it subverts the original paradigm of the game to create an experience of the numinous, which in spirit, is diametrically opposed to the original intent of the gameplay design. This artwork presents an exploration of, and allusion to, the often subtle and illusive concepts found in the sacred treatise The Seven Valleys (Bahá'u'lláh, 1991) in which the user engages in an experiential journey through the work. The user is faced with conditions and situations that provide motivation to question, explore and attempt to fathom the abstract sense of the numinous. Each of The Seven Valleys contains its own individual mysteries while at the same time contributing its part to the telling of a collective story.
