"This thesis proposes a Kristevan reading of the fantasy novels of Stephen Donaldson, with particular attention given to Kristeva's concepts of the symbolic order, the semiotic 'chora', abjection, the imaginery father and the thetic. It also identifies and comments on shortcomings in Kristevan theory. Donaldson's fantasies are dominated by male protagonists, one of whom is a leper while the others are rapists or murderers or else engaged in some form of violence or sexual perversion. This thesis not only offers an interpretation for this representation of disease and gross physical abuse, but also looks to the implication such corporeality brings to bear on the amatory relationships that the novels attempt to establish. "The thesis is organized into three broad sections. The first considers the ways in which the concept of the mother manifests in Donaldson's text and how the male protagonists respond to the maternal dynamic established in these books. [...] The second section of the thesis examines the role played by Donaldson's father figures. [...] The third section of [the] thesis examines the consequences of this male vulnerability with regard to its central characters who oscillate between symbolic standing and semiotic sprawl."
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. [...]

Description:
Arid areas are often overgrazed and dysfunctional with poor recruitment of desirable species, diminished control over resources and altered soil properties. Restoration ecology re-establishes these valued processes. State-and-transition models summarise knowledge of vegetation dynamics and tools for restoration, and encourage the incorporation of new information. The model developed here for semi-arid woodlands of north-west Victoria highlighted the unknown cause of observed, natural recruitment and the need for a technique, other than direct seeding and handplanting, for enhancing the recruitment of desirable species. I pursued these knowledge gaps for two dominant, woodland trees: Allocasuarina luehmannii and Casuarina pauper. Natural recruitment of juvenile C. pauper was found to be limited and primarily from root suckers. Extensive recruitment of A. luehmannii was shown to be mostly seedlings established following substantial reductions in grazing pressure since 1996. Seedlings were associated with areas devoid of ground flora near a female tree. The importance of competition between seedlings and ground flora, spatial variation in soil moisture and individual variation in the quantity of seed produced deserves further investigation to enhance future restoration success. Root suckers of both C. pauper and A. luehmannii can be artificially initiated, albeit in low numbers and this was found to be a feasible, new tool for restoration. Suckers are preceded by the growth of callus tissue on exposed or damaged, living, shallow roots. Both male and female trees can produce suckers and spring treatments may be more successful. Genetic fingerprinting of mature A. luehmannii and C. pauper trees in six populations did not identify any clonal individuals indicating that recruitment in the past has been from seedlings. Despite this, the high level of gene flow suggests that the impact of introducing small numbers of root suckers into existing populations is unlikely to impact negatively on the population genetics of these species.

The aim of the present study was to gain an understanding of the experience of treatment via an Internet-based cognitive behavioural self-help protocol for social anxiety disorder. Participants were four adults, aged between 22-46 years, who fulfilled DSM-IV-TR crriteria for a diagnosis of social anxiety disorder.
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.

The key issue of concern behind this study was that there have been recent concerns about the gender-based discrepancies in morbidity and mortality rates amongst men and the scant attention generally held by Australian men towards their own health and well-being ... the models of education that have emerged from this research as being appropriate for health delivery advice to urban, rural and disenfranchised men, suggest effective ways to reach out to Australian males.

"This dissertation illustrates an interdisciplinary sport science approach to further understand the interaction between physiology and performance in tennis. An integral theme throughout the experimental phases was the emphasis on obtaining information from actual competitive scenarios or settings that simulated a match environment. [...] This study extended the work of similar investigations through the multifaceted methods in which performance was quantified. Overall the thesis provides unique insight into the physiological demands of professional tournament tennis and the constraints these impose on performance. Furthermore, evidence was accrued to support some of the common preparatory and in-match behaviours used by players to enhance performance."

The consequences of introducing riparian shade on in-stream community structure has not been well explored in south-eastern Australia. With catchment managers focusing on revegetation of riparian zones, there is a need to understand, monitor, and predict changes in ecological patters and processes that may take place as a system shifts from an open to a shaded stream community. Presented in this thesis is a conceptual model portraying possible responses of a macrophyte community to light reduction as a result of the introduction of riparian vegetation. This model was tested in the field by artificially shading sites (three shade treatments) to observe the direct effects of light reduction on Phragmites australis growth and structure and flow-on effects to associated in-stream biota."

"Through a review of the art of late antiquity and early Christianity, the study examines the nature of, and tension between, superstion and belief. It debates the implicit question 'is all religion superstition?' in an attempt to provide a sound basis for the presentation of reasons for my personal unwilingness to 'disallow belief' in the mysteries of the Faith, despite doubts on their content."

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.

Stories have been engaging humans for thousands of years, but in interactive narrative environments, the narrative is perceived to diminish as the source of engagement. One reason for this apparent diminution, is that in interactive environments there has been difficulty in understanding the relationship between design of the unfolding story, and the ability of a user within the story to alter the course of events. As yet there are no standard or accepted evaluative methods to understand interaction at a granular level, and to understand how stories and narratives flow across the expanse of technologies and mixed realities that characterise the way people communicate, share knowledge and are entertained. This thesis presents a novel methodology called the Four-Factor Framework, that takes as its premise that there are four fundamental elements in interactive stories and narratives that can be observed.

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.

A paired set (PS) refers to the coupling of exercises targeting agonist-antagonist muscle groups and performed coincidentally. Although PS have been prescribed by strength and conditioning coaches as a means of developing strength and power, scientific research investigating their efficacy is limited. The aim of this research was to investigate not only the efficacy of PS, but also their efficiency.

The research presented in this thesis is two-fold: on the one hand, major data mining problems are reformulated as mathematical programming problems. These problems should be carefully designed, since from their formulation depends the efficiency, perhaps the existence, of the solvers. On the other hand, optimisation methods are adapted to solve these problems, most of which are nonsmooth and nonconvex. This part is delicate, as the solution is often required to be good and obtained fast. Numerical experiments on real-world datasets are presented and analysed.

The overall aim of this portfolio is to discuss [...] understanding of the curriculum process surrounding the development of the Health and Physical Education Curriculum and Standards Framework II (HPE CSFII) and its implementation in a Victorian secondary school. The unit of analysis was a group of physical educators from Newviews Secondary College. Throughout 2002, interviews, surveys and document analysis were used to see how 'how and if' the HPE CSFII was being adopted and 'implemented' by the group.
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.[...]
Description:
This study investigated how student expectations, experiences and involvement in physical education teacher education impacted upon and shaped identity development. The research focused on student social interactions and identified a range of behaviours and practices which reinforced student notions of what it means to be a physical educator. [...] The research itself was conducted within a creative analytical practice framework resulting in the following research products: the thesis text; a collection of one act plays titled, 'Plays from the identity playground', written about student social experiences; a CD which includes the filmed production of one of the plays 'Boys' training', and 'I can be this: a phototext', which presents key 'photographic' themes as insights into PETE student social events and activities.
