- Description: "Arsenic is a common soil contaminant in Australia and worldwide. There is a need to find safe, effective and economic methods to deal with this problem. The soils used in this research were collected from central Victoria. They were contaminated with arsenic by historic gold mining activity or by past sheep dipping practices. This research investigated ten different leaching agents for their effects on three different arsenic contaminated soils. [...] Electrokinetic experiments were conducted on three arsenic contaminated soils. [...] The arsenic in these soils appears to be relatively stable and immobile under oxidising conditions. The soils had a high iron content which assists in the stabilisation of arsenic. This is beneficial with respect to the environmental impact of the arsenic contamination, however, it remains an obstacle to low cost electrokinetic remediation."

Letters to Francisco : Negative imagery in art and the depiction of microstructural elements of the human body
- Authors: Milos, Emil
- Date: 2006
- Type: Text , Thesis , Masters
- Full Text:
- Description: "The thesis itself, involves some psychological and philosophical aspects and thoughts about fear as the main mover in the so called negative aesthetic. This specific method of self-expression, its possible triggers and the reasons that may initiate art creation on the basis of pessimistic and ugly imagery have not been discussed to a great degree in the past. Generally, the content of this writing is focused on the fictious correspondence between two engravers and printmakers. These invented letters serve as an exposé for practical findings and thoughts about the author's works executed during the period 2005-2006."

Continuing "assimilation"? : A shifting identity for the Tiwi 1919 to the present
- Authors: Morris, John
- Date: 2003
- Type: Text , Thesis , PhD
- Full Text:
- Description: The Tiwi are the indigenous people of the Tiwi Islands, located off the Northern Territory mainland. In 1919, as a unique and distinct people they appeared to be in a position to maintain their identity, to resist absorption into western culture and to avoid some of the serious social problems that came to affect some other Indigenous communities. While aspects of the Tiwi culture and lifestyle were gradually modified or abandoned through contact with outside societies between 1919 and 2000, other traits remained strong or were strengthened. These included their relationship with the land, the local language, dancing and singing, and adoption customs. Forms of visual art, some introduced, brought fame to the Tiwi. Government policies on Indigenous matters changed dramatically over the twentieth century. The earlier ones, including assimilation programmes were discriminatory and restrictive. Later approaches to Aboriginal and Islander welfare, including land rights, had significant consequences for the Islanders, some beneficial, others detrimental in nature. From the 1970s, the departure of resident missionaries and government officers from the islands led to an influx of private European employees. The exposure to these people added to that which the Tiwi experienced as they travelled far beyond their islands. After 1972, the policies of self-determination and, then, self-management placed enormous strains on the Tiwi as they strove to meet the requirements of government, private enterprise and the wider society. New forms of land and local government controls replaced the law of the elders. A younger, western-educated generation now spoke on behalf of the people. Ultimately, under the influence of outside pressures, degrees of socio-cultural absorption occurred in the islands even though the official policy of assimilation had been abandoned. Fortunately, the strong identity of the Tiwi ensured a level of social cohesion capable of combating full assimilation into a wholly western lifestyle.

- 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.

Restoration ecology in the semi-arid woodlands of north-west Victoria
- Authors: Murdoch, Fiona
- Date: 2005
- Type: Text , Thesis , PhD
- Full Text:
- 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.

When urban policy meets regional practice : Evidence based practice from the perspective of multi-disciplinary teams working in rural and remote health service provision
- Authors: Murphy, Angela
- Date: 2004
- Type: Text , Thesis , PhD
- Full Text:
- Description: "In the main, contemporary research on Evidence Based Practice (EBP) has taken place within metropolitan locations, and has offered urbocentric solutions and insights. However the transferability of these developments to rural services is untested empirically. In addition, evidence development and studies on the implementation of this evidence have tended to be discipline-stream-specific; there has been very little research into either the development of multi-disciplinary evidence guidelines or the implementation of EBP from the perspective of individual practitioners working within multi-disciplinary teams. This research shortfall has provided the rationale for this study...."

Spiritual Art : evoking the numinous using a 3D computer game engine
- Authors: Nelson, Christopher
- Date: 2007
- Type: Text , Thesis , Masters
- Full Text:
- 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.

A study of multiple perspectives and knowledge in adverse drug reaction decision-making : Volume 1
- Authors: O'Brien, Michelle
- Date: 2004
- Type: Text , Thesis , PhD
- Full Text:
- Description: Injury and illness associated with drugs are major problems in Australia and around the world, despite significant developments in the area of adverse drug reaction (ADR) decision support technology. The aims of this thesis are: to investigate the ADR decision domain; to determine factors that may assist in the prevention, detection and management of ADRs; and, to inform the pre-requirements analysis phase of the development of decision support systems. An approach has been taken that permits open and grounded study of the decision environment. This approach can then be used to frame and inform the design of an ADR decision support system. Fifteen case studies that comprise self selected consumers, the treating medical practitioner/s and expert perspectives of a single instance of an ADR (fifteen in-depth consumer interviews, eight in-depth medical practitioner interviews and 30 expert written questionnaires), have been collected and analysed using a grounded theory approach, a symbolic interactionist theoretical framework and a social constructionist epistemology. The analysis was performed from three perspectives: individual case study analysis (all interviews for an instance of an ADR); group analysis (consumer, medical practitioner and expert views) and analysis combining the individual case studies and groups of data. Concepts, themes and theory have emerged from these data in the following areas: • the contribution of the differences in understanding of the core concepts within this domain, to misunderstandings between decision-makers; • the consumer as a diagnostic decision-maker in the ADR decision domain; • differential diagnostic strategies used by the consumers and medical practitioners; • complexities in the ADR decision domain that make diagnosis difficult; • the role of ADR information in consumer and medical practitioner decision-making; • decision types used by consumers and medical practitioners in the ADR decision domain; • resources used by consumers, medical practitioners and experts to inform their ADR decisions; • decision-making with partial knowledge of the consumer case history, drug behaviour and diseases; • the impact of suspected ADRs on consumers and on future decision-making; • medical practitioner/consumer decision-making models; and, • reasons for low ADR reporting and the impact on the development of new ADR knowledge. The results above suggest the following: • The ADR decision domain is more complex than the current ADR decision support focus and that broadening this focus may assist in providing a more complete and useful decision support solution. • Improving the prevention, detection and management of ADRs requires more than providing prescribers with up to date ADR information. Other important factors are sharing of information, awareness of the role of the consumer, a collaborative approach between the consumers and medical practitioners, and generation of new ADR knowledge. • A grounded theory analysis of case study data using the theoretical perspectives of social constructionism and symbolic interactionism provided insight into this domain from the perspectives of multiple decision-makers. This may be an approach that can be used by systems analysts to inform the requirements analysis phases of decision support within other domains. The results of this qualitative work are preliminary. Future work is required to confirm and expand these results.

The Sexual beliefs, attitudes and script of men convicted of sexual offences against children : An empirical investigation
- Authors: Owen, Karen
- Date: 2007
- Type: Text , Thesis , PhD
- Full Text:
- Description: Community concern about sexual offending places continued pressure on correctional services to refine treatment and reduce re-offending. While cognitive processes have been identified as a key element in the development and maintenance of sexual offending, more research on the precise nature of these processes is required. The current study, based on Ward and Siegert’s Pathways Model, involved 100 male offenders of various types: 25 intra – familial sex offenders against children, 25 extra-familial sex offenders against children, 25 sex offenders who chose adult victims, and 25 convicted of non-sexual offences. There was also a control group of 25 non-offenders. The quantitative data, derived from a series of questionnaires concerning childhood and sexual experiences, provided evidence that the two types of child sex offender differed from the other groups with respect to their expectations of sexual behaviour among children, their experience of sexual abuse and neglect as children themselves, and, paradoxically, their current high self-esteem. In addition, scripts relating to hypothetical consenting adult sexual relations and sexual contact with a child were collected from the 50 sex offenders against children. The script content suggested that, compared with intra - familial offenders, extra-familial offenders had notably unrealistic, naïve and romanticised scripts for adult relationships and more sophisticated scripts for offences against children. The latter suggested that scripts might serve as a mediating function in offending behaviour and that offenders acquired a degree of task domain expertise. Despite some inherent problems undertaking research with the sex-offender population, the findings confirmed that sex-offenders do not constitute a homogenous group and that the pathways model offers a unique perspective on how males become and develop their capacity as sex-offenders, how they sustain a positive view of themselves, and how they continue to commit offences. Finally, the model was considered in terms of its capacity to suggest ways to better target treatment efforts to specific groups of sexual offenders to further reduce their rate of recidivism

Harambe : Strategic alliance formation and performance evaluation in the tourism sector of travel
- Authors: Pansiri, Jaloni
- Date: 2006
- Type: Text , Thesis , PhD
- Full Text:
- Description: "This thesis investigates the influence of company and executive characteristics on strategic alliance formation (decision to form alliances, alliance type selection and choice of alliance partners) and performance evaluation of alliances, in the Australian tourism industry sector of travel. The significance of forming strategic alliances as a way of achieving 'harambe' is emphasised throughout this thesis. 'Harambe' is a ki-Swahili term meaning "to pull together, or to work together or to pull the same rope together at the same time" in harmony. The idea here is that companies pool their resources together through strategic alliances to be able to achieve their strategic goals and objectives. The research focuses on three travel sub-sectors - travel agencies, tour operators and wholesalers and how these sub-sectors relate with those of transport and accommodation." -
