- Description: The relatively new field of stream mining has necessitated the development of robust drift-aware algorithms that provide accurate, real time, data handling capabilities. Tools are needed to assess and diagnose important trends and investigate drift evolution parameters. In this paper, we present two new and novel visualisation techniques, Pixie and Luna graphs, which incorporate salient group statistics coupled with intuitive visual representations of multidimensional groupings over time. Through the novel representations presented here, spatial interactions between temporal divisions can be diagnosed and overall distribution patterns identified. It provides a means of evaluating in non-constrained capacity, commonly constrained evolutionary problems.

- Description: To date, most research into the implications of the Internet for small and medium size enterprises (SMEs) has focused on individual business barriers to information and communication technologies (ICT) and e-business adoption. Such research has shown that SMEs tend to be time and resource-poor, with their size being their main disadvantage vis-à-vis ICT adoption. Government intervention designed to overcome such barriers and facilitate adoption of ICT has not markedly increased the uptake of e-business by SMEs. In this discussion paper, the authors posit that the current approach to ICT adoption interventions fail to take into account the incremental nature of the SMEs e-business learning processes. An incremental learning model adapted from Earl (2000) is presented that positions ICT adoption as an evolutionary process and stresses the need for continuous learning and change. To help small business owners articulate, value and meet their evolving e-business needs, the authors suggest that ICT adoption strategies should focus on facilitating not only the acquisition of skills and knowledge, but also the development of e-business networks which underpin the SME ICT adoption process.

- Description: There is continued debate between researchers, policy makers and regional communities on the effectiveness of research in identifying and engaging with regional issues and transferring this research to facilitate polices and initiatives that are adaptive and relevant. This paper reviews these current trends in thinking and describes a model of regional engagement where researchers, decision makers and community are beginning to work together to establish an effective framework to facilitate adaptive decision making, social learning and participatory research initiatives at a regional scale. The paper describes the evolution of the Water in Drylands Collaborative Research Program (WIDCORP) in Western Victoria. The model provides insights and highlights difficulties in converting research into creative solutions for sustainable regional development. Co-location, bridging partnerships across disciplines to deliver regional research needs, and developing good communication are key elements of this model. It also suggests that models of this type may be a stepping stone to integrate research into regional development decision making.

- Description: Since Roland Wilson’s (1951) tribute to L. F. Giblin as ‘the grand old man’ or father figure of modern Australian economics there has been a tendency to underestimate the achievements and legacy of Douglas Berry Copland. It became fashionable, moreover, with the post-war generation of economists to belittle his contribution to interwar Australian economic thought especially that relating to stabilisation policy. Copland was quite aware of the chiselling away at his reputation. Commenting to a friend while reading Harrod’s biography of Keynes he wrote ‘Still reading Keynes and I remember most of the controversy and the discussion he was involved from the 1920’s onwards. A few of us had been working on similar lines and I have somewhere a set of memorandums to the government of NSW from 1932 to 1936 urging with all the persuasion I could muster an expansionist policy, but we could not get pass the Commonwealth Treasury. It would be fun to dig them out now and circulate for the younger brethren who still think we are past praying for. I’m sure he (Keynes) would disown Coombs and his school if he was with us now’. By that reflection Copland revealed not just his close dealings with Keynes but his fear that a hydraulic Keynesianism was taking hold within the Australian economics fraternity. It also showed Copland’s pride of the policy advocacy and controversies he had actively participated in during the 1930’s.

- Description: Improvements of truck fuel economy are being considered using a flywheel energy storage system concept. This system reduces the amount of mechanical energy needed by the thermal engine by recovering the vehicle kinetic energy during braking and then assisting torque requirements. The mechanical system has an overall efficiency over a full regenerative cycle of about 70%, about twice the efficiency of battery-based hybrids rated at about 36%. The technology may improve the vehicle fuel economy and hence reduced CO2 emissions by more than 30% over driving cycles characterized by: frequent engine start/stop, vehicle acceleration, brief cruising, deceleration and stop. The paper uses engine and vehicle simulations to compute: first the fuel benefits of the technology applied to passenger cars, then the extension of the technology to deal with heavy duty vehicles.

- Description: This research presents a classifier that aims to provide insight into a dataset in addition to achieving classification accuracies comparable to other algorithms. The classifier called, Automated Weighted Sum (AWSum) uses a weighted sum approach where feature values are assigned weights that are summed and compared to a threshold in order to classify an example. Though naive, this approach is scalable, achieves accurate classifications on standard datasets and also provides a degree of insight. By insight we mean that the technique provides an appreciation of the influence a feature value has on class values, relative to each other. AWSum provides a focus on the feature value space that allows the technique to identify feature values and combinations of feature values that are sensitive and important for a classification. This is particularly useful in fields such as medicine where this sort of micro-focus and understanding is critical in classification.

- Description: The success of the tourism industry is highly dependent on the quality of business operations. To run tourism businesses well, operators need to be skilled, flexible and innovative in order to maintain and enhance competitiveness. The aim of this paper is to share the authors’ initial insights into tourism industry capacity building via flexibly delivered online skilling and knowledge sharing. This discussion paper builds on the work of online learning research for small tourism firms conducted in Europe and compares the European approach and considers how the European approach to content development and delivery informed a recently piloted Australian online skilling program. The paper also provides insights into online user behaviour and challenges fundamental research expectations. While both programs have focussed tourism information and skills development, the Australian pilot has been embedded in the Tourism Accreditation Board of Victoria and is being utilised to enable operators to complete tourism industry accreditation. Aiming to raise industry standards and move away from ineffective silo approaches to industry training and capacity building, this pilot reflects the importance of and contributes to the development of an effective national voluntary accreditation system.

- Description: In 2001 the Victorian Government launched its Community Building initiative. As part of this initiative the government funded 11 locally based community building demonstration projects. One of these projects is located within the Pyrenees Shire. In this discussion paper the authors examine the Pyrenees Shire’s Community Building Demonstration Project, describing the program and its objectives. They focus on the factors which have had a significant impact on the community building process within the municipality, identifying factors which have both facilitated and impeded the process. In terms of facilitating factors they identify a number: the involvement of community champions, strong local government support and community readiness, the capacity to deliver ‘runs on the board’ early in the life of the project, along with a flexible planning process. Conversely, they identify factors which have impeded the community building process in the Shire. Lack of continuity of personnel, an inability to develop shared understanding on occasions and difficulties associated with engaging disparate groups are described. This paper is significant for a number of reasons. In the first instance, it contributes useful, ‘real time’ insights into the implementation of community building in regional Victoria. Secondly it may, through its contribution to theory building and managerial practice, develop and strengthen community building programs in the future. Finally, at the level of public policy, it may contribute to the growing body of knowledge around the efficiency, effectiveness and appropriateness of these types of regional interventions.

- Description: Personal information stored in large government databases is a prime target for criminals because of its potential use in identity theft and associated crime, such as fraud. In 2007-2008, a number of very high-profile cases of data loss within the British Government, its departments and non-departmental bodies raised three pressing issues of public significance: (1) how broad was the loss across agencies; (2) how deep was each loss incident; and (3) what counter-measures (organisational and technical) could be put in place to prevent further loss? This paper provides a chronological review of data loss incidents, and assesses the potential to mitigate risk, given organisational structures and processes, and taking into account current government calls for further medium and long-term acquisition and storage of citizen's private data. The potential use of the "lost" credentials is discussed in the context of identity theft. © 2009 IEEE.

- Description: We propose a method for procedural modeling and animation of cartoon water effects such as water caustics and foamy water. In our method we emulate the visual abstraction of these cartoon effects by the use of Voronoi diagrams and the motion abstraction by designing relevant controlling mechanisms corresponding to each effect. Our system enables the creation of cartoon effects with minimal intervention from the animator. Through high-level initial specification, the effects are animated procedurally in the style of hand-drawn cartoons. © 2010 IEEE.

- Description: Cardiovascular autonomic neuropathy (CAN) is one of the important causes of mortality among diabetes patients. Statistics shows that more than 22% of people with type 2 diabetes mellitus suffer from CAN and which in turn leads to cardiovascular disease (heart attack, stroke). Therefore early detection of CAN could reduce the mortality. Traditional method for detection of CAN uses Ewing's algorithm where five noninvasive cardiovascular tests are used. Often for clinician, it is difficult to collect data from for the Ewing Battery patients due to onerous test conditions. In this paper, we propose a hybrid of wrapper-filter approach to find novel features from patients' ECG records and then generate decision rules for the new features for easier detection of CAN. In the proposed feature selection, a hybrid of filter (Maximum Relevance, MR) and wrapper (Artificial Neural Net Input Gain Measurement Approximation ANNIGMA) approaches (MR-ANNIGMA) would be used. The combined heuristics in the hybrid MRANNIGMA takes the advantages of the complementary properties of the both filter and wrapper heuristics and can find significant features. The selected features set are used to generate a new set of rules for detection of CAN. Experiments on real patient records shows that proposed method finds a smaller set of features for detection of CAN than traditional method which are clinically significant and could lead to an easier way to diagnose CAN. © 2010 IEEE.

- Description: Enrichment programs for Research Higher Degree (RHD) students are an endeavour undertaken by all Australian Universities. Most of these enrichment programs have in the main been centred on the generic skills required to expedite the research program, for example software skills, information gathering and collating skills, language development programs and seminars on various methodologies. There are some examples where enrichment programs have focused on leadership. These programs often assume not only that leadership can be taught, but also that a traditional seminar/lecture approaches to such a curriculum is a practical, efficient and effective approach to leadership education. This paper questions these assumptions by arguing for a more experientially-based approach to leadership education at the RHD level. This approach has demanded a consideration of pedagogical approaches outside, or peripheral, to the traditional approaches of RHD training. A specific example of a leadership program that incorporates experiential learning in is presented. The paper delineates a brief overview of experiential approaches to education, followed by a more specific review of the potential role these approaches can play in leadership education.

- Description: Drug-drug interaction is one of the important problems of Adverse Drug Reaction (ADR). In this paper we develop an optimization approach for the study of this problem. This approach is based on drug-reaction relationships represented in the form of a vector of weights, which can be defined as a solution to some global optimization problem. Although this approach can be used for solving many ADR problems, we concentrate here only on drug-drug interactions. Based on drug-reaction relationships, we formulate this problem as an optimization problem. The approach is applied to different classes of reactions from the Australian Adverse Drug Reaction Advisory Committee (ADRAC) database.
