The High Court decision in Mabo v Queensland (No 2) was interpreted by some as bringing to an end a history of discrimination and dispossession of indigenous peoples' lands. In this respect it was located within the new history movement in Australia - a movement which has raised awareness of the impact that colonisation has had on indigenous peoples in Australia. ln this thesis the extent to which Mabo was in fact a product of the new history movement in Australia is examined. An analysis of the results in the more recent High Court cases on native title such as Western Australia v Ward and Members of the Members of the Yorta Yorta Aboriginal Community v Victoria reveals that the promises that came with native title recognition in Mabo have not been fulfilled. ln Ward the native title claim was partially accepted; in Yorta Yorta lhe claim was completely rejected. But as the analysis further reveals the shortcomings of the native title regime as demonstrated by these cases can be partly located in the Mabo decision itself. One of the contributions that some new historians have made to the writing of Australian history has been to reveal how the perceived differences between indigenous peoples and the colonists resulted in the perception of indigenous peoples as inferior beings. In turn, such perceptions worked to legitimise their dispossession in the native title context, indigenous peoples are no longer to be perceived as inferior (the rejection of the terra nullius doctrine in Mabo was an acknowledgement that indigenous peoples did have their own laws and social organisation) However the perception that they are different remains in the way that laws for them are constructed: native title may be recognised by the common law, but it is not part of the common law. As it is argued in this thesis the perceived differences in the origins of native title and the Australian common law has resulted in the inferior r treatment of native title. Potential solutions are canvassed in the thesis. Included among them is the need to give recognition to Aboriginal sovereignty However, it is concluded that if any change is to take place it must involve changing perceptions of indigenous peoples so that the protection of their interests may be more broadly construed as being in the interests of Australia.

Decision-making in the arts sector is sometimes seen as problematical as many of the 'primary' decisions are made away from the 'primary' creative practice. The criteria for decision-making may be perceived as based on organisational or financial need, rather than creative output or social need. It is my view that the perceptions need testing. To do this I needed a way of understanding how decisions are reached in a variety of different contexts within the arts and cultural sector. Most would concede that decision-making is not a precise science. My quest thus became finding an appropriate research methodology for these explorations. Action research emerged as a useful framework for adding understanding within dynamic situations. This thesis reports on the usefulness of participatory action research as a tool for the exploration of decision-making processes by a range of people working within the arts and cultural sectors. Incremental view research has attracted extensive research in recent years. View maintenance techniques have been developed for the relational model, the temporal model, the object-oriented model, and the semistructured model. However, research into view maintenance in the non relational model is not complete and, in particular, the issue of view maintenance in nested relational databases and in object- relational (OR) databases has not been investigated. this motivates our research in this thesis. / thesis (MBus(Arts,CulturalManagement))--University of South Australia, 2003.

Clinical decision-making (CDM) research has focused on diagnostic reasoning, CDM models, factors influencing CDM and the development of expertise. The research approaches used, including phenomenology, have not addressed the question of how CDM is perceived and approached by nurses. This study describes perceptions of CDM in relation to patients in pain using a phenomenographic methodology. At semi-structured interviews, participants were asked to recall their responses to a situation involving a patient in pain. The responses fell into four categories: (1) the effect of the clinical environment; (2) the role of other health professionals; (3) the place of the patient; and (4) the role of experience. Examples of differences in perceptions that were likely to impact on the nurses� approach to CDM include: the ongoing effects of time and workload demands on CDM; nurses are initially dependent but were eventually able to make decisions autonomously; the patient who may be peripheral or central to CDM; and the nurses� move from the use of theoretical principles to experiential knowledge as reflection-on-practice is employed. Perceptions in all categories are strongly implicated in the nurses� sense of confidence and independence. Implications for nursing practice and nursing education suggested by the findings relate to the number of areas in which graduates work in the first year of practice, the size of new graduate workloads, graduate transition programs, the place of reflection-on-practice and undergraduate (UG) program clinical experience patterns. Among issues for further research arising from the study are: replication of the study; detailed examination of the development of CDM in the first year of nursing practice and during UG nursing education programs; the role of other health professionals in the development of CDM behaviour; the links between CDM and clinical knowledge development; and the type of clinical environments that foster confidence and independence. A conclusion of the study is that the way CDM is approached is influenced by the amount, quality, relevancy and recency of clinical experience. In this study, phenomenography was shown to be an appropriate approach to the description of nurses� perceptions of CDM in relation to patients in pain. In addition, nurses� changing perceptions over two years and the subsequent effect on CDM behaviour were described.

Doctor of Philosophy / Multiple sclerosis (MS) is the most common neurological disease affecting young adults. MS affects approximately 1 in 1000 people and, like other autoimmune diseases, women are more likely to be affected than men. The illness typically onsets between the ages of 20 and 40, and hence usually affects women of child-bearing age. The course of the MS is often unclear for years after diagnosis and since most women are diagnosed in their child-bearing years, they often have to make reproductive choices before their prognosis is clear and while the future remains uncertain. For women with MS, starting a family is an individual choice that needs to balance the importance of motherhood for the woman and her partner against the risks that she will be unable to care for the infant or child as a result of increasing disability. In other areas of medicine where finely balanced decisions are required, there has been a recent proliferation of decision aids that aim to inform people of the benefits and risks of opposing courses of action. In addition, decision aids help patients to weigh their values against the risks and benefits to make an informed decision. Despite the existence of over 200 decision aids to help patients consider decisions related to their medical conditions, not one exists that deals with the decision of whether or not to have a family for women with a chronic disability, such as MS. This thesis developed and evaluated a decision aid for women with MS to help them decide whether to start, forego or enlarge their families. The study utilised the criteria set out for the development of decision aids, according to the Cochrane Systematic Review of Patient Decision Aids (O'Connor et al., 2003). The first aim was to determine the proportion of women who are undecided about the motherhood choice and for whom a decision aid may be relevant. Results found that the motherhood choice was relevant to 46% of the women who responded to an initial mail-out. The second study aimed to establish women’s current concerns and thoughts regarding pregnancy and motherhood, and their response to the pilot decision aid. Twenty women participated in qualitative interviews and results supported previous findings that the mother’s health concerns, coping with parenting and societal attitudes are significant concerns when considering this decision. This study further identified concerns from different groups that had a direct impact on the decision to have children, including the experience of parenting, the child’s well-being and the timing and pressure of the decision. The main study was a randomised controlled trial of the decision aid aiming to determine whether the decision aid facilitated decision-making in women with MS. The study confirmed that the decision aid presented a balanced view to women, increased knowledge, reduced decisional conflict, increased decisional self-efficacy and certainty of the decision, and was free from adverse effects on psychopathology. The final component of the study was a 12 month follow-up which aimed to explore the long-term effectiveness of the decision aid and what aspects were valued by the women who received it. It was found that over time, women in the intervention group did maintain their certainty, but women in the control group also became more certain of their choice. At follow-up, the difference in certainty was no longer significant between the two groups. However, women did report that the intervention was useful in (a) providing access to information previously unavailable or difficult to obtain, (b) facilitating communication between women, their partners and health care professionals, (c) aiding them in considering and utilising their networks of support, and (d) preparing them for potential difficulties. In summary, this thesis developed and evaluated a decision aid for women with MS who are considering motherhood. The results showed that many women were undecided and, in the absence of good information on the topic, many women had concerns about pregnancy and parenthood. The decision aid was shown to be effective across a range of measures and free from adverse psychological effects. Hence, this is evidence-based resource can now be recommended for those women with MS who are currently contemplating motherhood.

This dissertation explores and analyzes the performance of several Bayesian anytime inference algorithms for dynamic influence diagrams. These algorithms are compared on the On-Line Maintenance Agent testbed, a software artifact permitting comparison of dynamic reasoning algorithms used by an agent on a variety of simulated maintenance and monitoring tasks. Analysis of their performance suggests that a particular algorithmic property, which I term sampling kurtosis, may be responsible for successful reasoning in the tested half-adder domain. A new algorithm is devised and evaluated which permits testing of sampling kurtosis, revealing that it may not be the most significant algorithm property but suggesting new lines of inquiry. Peculiarities in the observed data lead to a detailed analysis of agent-simulator interaction, resulting in an equation model and a Stochastic Automata Network model for a random action algorithm. The model analyses are extended to show that some of the anytime reasoning algorithms perform remarkably near optimally. The research suggests improvements for the design and development of reasoning testbeds. / Graduation date: 2002

Because of the explosion of digital and online text information, automatic organization of documents has become a very important research area. There are mainly two machine learning approaches to enhance the organization task of the digital documents. One of them is the supervised approach, where pre-defined category labels are assigned to documents based on the likelihood suggested by a training set of labeled documents; and the other one is the unsupervised approach, where there is no need for human intervention or labeled documents at any point in the whole process. In this thesis, we concentrate on the supervised learning task which deals with document classification. One of the most important tasks of information retrieval is to induce classifiers capable of categorizing text documents. The same document can belong to two or more categories and this situation is referred by the term multi-label classification. Multi-label classification domains have been encountered in diverse fields. Most of the existing machine learning techniques which are in multi-label classification domains are extremely expensive since the documents are characterized by an extremely large number of features. In this thesis, we are trying to reduce these computational costs by applying different types of algorithms to the documents which are characterized by large number of features. Another important thing that we deal in this thesis is to have the highest possible accuracy when we have the high computational performance on text document categorization.
