- Description: This paper describes an innovative cross-institutional learning partnership that was designed to foster the learning of both Pre-Service Teachers (PSTs) and students and teachers from a local regional Secondary College. Around 150 Grade Nine (13-14 year old) students took part in a purpose-designed activity day at the university that was organised and conducted by 34 second year PSTs as part of their teacher education program. This project was designed as an authentic teaching experience for PSTs that would enable them to translate theory from their teacher education course into teaching practice. At the same time the secondary students were offered a range of learning experiences informed by school-derived curriculum. These specifically focused activities contributed to the students’ school based learning programs whilst also encouraging them to think of university as a future option. In this paper reflections, utilizing a self-study methodology, are provided by the lecturers who developed and implemented the program. The lecturers describe and discuss what they observed about the learning of the PSTs. Many of the PSTs indicated strongly that they were able to engage in a scaffolded, authentic teaching experience as preparation for their initial school placements. Overall, the evidence suggests that the initiative offered a powerful learning experience that enabled PSTs to connect theory with teaching practice.

- Description: Frequency Response Analysis (FRA) has been growing in popularity in recent times as a tool to detect mechanical deformation within power transformers. To conduct the test, the transformer has to be taken out of service which may cause interruption to the electricity grid. Moreover, because FRA relies on graphical analysis, it calls for an expert person to analyse the results as so far, there is no standard code for FRA interpretation worldwide. In this paper an online technique is introduced to detect the internal faults within a power transformer by constructing the voltage-current (V-I) locus diagram to provide a current state of the transformer health condition. The technique does not call for any special equipment as it uses the existing metering devices attached to any power transformer to monitor the input voltage, output voltage and the input current at the power frequency and hence online monitoring can be realised. Various types of faults have been simulated to assess its impact on the proposed locus. A Matlab code based on digital image processing is developed to calculate any deviation of the V-I locus with respect to the reference one and to identify the type of fault.

- Description: Frequency response analysis (FRA) is gaining global popularity in detecting power transformer winding movement due to the development of FRA test equipment. However, because FRA relies on graphical analysis, interpretation of its signatures is still a very specialized area that calls for skillful personnel to detect the sort and likely place of the fault as so far, there is no reliable standard code for FRA signature classification and quantification. This paper investigates the impact of transformer winding axial displacement on its FRA signature as a step toward the establishment of reliable codes for FRA interpretation. In this context a detailed model for a singlephase transformer is simulated using 3D finite element analysis to emulate a close to real transformer. The impact of axial displacement on the electrical distributed parameters model that are calculated based on the transformer physical dimension is examined to investigate how model’s parameters including inductance and capacitance matrices change when axial displacement takes place within a power transformer.

- Description: Automatic 3D extraction of building roofs from remotely sensed data is important for many applications including city modeling. This paper proposes a new method for automatic 3D roof extraction through an effective integration of LIDAR (Light Detection And Ranging) data and multispectral orthoimagery. Using the ground height from a DEM (Digital Elevation Model), the raw LIDAR points are separated into two groups. The first group contains the ground points that are exploited to constitute a `ground mask'. The second group contains the non-ground points which are segmented using an innovative image line guided segmentation technique to extract the roof planes. The image lines extracted from the grey-scale version of the orthoimage are classified into several classes such as `ground', `tree', `roof edge' and `roof ridge' using the ground mask and colour and texture information from the orthoimagery. During roof plane extraction the lines from the later two classes are used to fit roof planes to the neighbouring non-ground LIDAR points. Finally, a new rule-based procedure is applied to remove planes constructed on trees. Experimental results show that the proposed method successfully removes vegetation and offers high extraction rates.

- Description: Clinical decision-support is gaining widespread attention as medical institutions and governing bodies turn towards utilising better information management for effective and efficient healthcare delivery and quality assured outcomes. Amass of data across all stages, from disease diagnosis to palliative care, is further indication of the opportunities and challenges created for effective data management, analysis, prediction and optimization techniques as parts of knowledge management in clinical environments. A Data-driven Decision Guidance Management System (DD-DGMS) architecture can encompass solutions into a single closed-loop integrated platform to empower clinical scientists to seamlessly explore a multivariate data space in search of novel patterns and correlations to inform their research and practice. The paper describes the components of such an architecture, which includes a robust data warehouse as an infrastructure for comprehensive clinical knowledge management. The proposed DD-DGMS architecture incorporates the dynamic dimensional data model as its elemental core. Given the heterogeneous nature of clinical contexts and corresponding data, the dimensional data model presents itself as an adaptive model that facilitates knowledge discovery, distribution and application, which is essential for clinical decision support. The paper reports on a trial of the DD-DGMS system prototype conducted on diabetes screening data which further establishes the relevance of the proposed architecture to a clinical context.

- Description: The current Australian higher education policy environment has been shaped by the Commonwealth targets for 40 per cent of 25- to 34-year-olds to hold a bachelor’s-level degree or higher by 2020, and for low socio-economic status (LSES) participation to increase to 20 per cent by 2025. Universities have responded to this policy agenda by increasing enrolments and developing a range of pathway programs, including enabling programs, VET articulation agreements and nested awards. For “selecting”, research-intensive institutions such as Monash University, responding to the access agenda is fraught with tensions concerning institutional identity, status and contribution. In developing a set of access strategies for mature-age learners, Monash University is seeking to broaden access without compromising academic status. This involves creating mechanisms to engage high-potential LSES mature-age students through recruitment and selection processes with activities that assist them to translate their workplace and community experiences into the university environment, and provide a balance of opportunity, support and challenge.

- Description: While alternative educational settings in Australia have expanded over the past two decades, there has been little formal research conducted into teacher perceptions of what it means to teach outside the mainstream. This paper outlines part of a longitudinal study involving the School for Student Leadership (SSL), an alternate educational setting in Victoria, Australia, which offers residential programs for Year 9 students. The SSL began operating in 2000 as the Alpine School situated at Dinner Plain and since then two further campuses have been added. A research partnership between Monash University Gippsland and the SSL began in 2001, with this component commencing in 2009 involving a mixed methods study consisting of both surveys and interviews. The focus of this paper is the qualitative findings resulting from interviews with 33 teachers across the 3 campuses. While a small body of literature relating to environmental and experiential education (Brown, 2006, Schartner, 2000, Simmons, 1988, Smith-Cabasto & Cavern, 2006) from a teaching perspective does exist, none really captures the breadth of the type of program offered through the SSL, which does not sit in isolation from broader educational, social and global discourses. While there is an ongoing debate about how we should educate young people there are some points of general agreement. One is that we live in a world of rapid global, technological and social change and education should equip young people to deal with these changes. This particular research provided an opportunity to seek teachers' perceptions about whether this goal was easier to achieve in a non-traditional setting. A particular focus was on participants' current perceptions about their role as 'teacher' and whether it differed depending on the setting. The findings provided interesting insights about the focus of the teachers that choose to become involved, with most suggesting that they were searching for more meaningful ways to connect their pedagogy and practice. They also felt that mainstream settings rarely provided opportunities for the development of substantive relationships with students. There was an acknowledgement that the alternate setting of the SSL did provide a greater opportunity for equipping students to deal with change but this also required teachers to respond differently, shifting the emphasis from content to context and from being a teacher to being an educator, facilitator or mentor.

- Description: In this paper we provide empirical data of the performance of the two most commonly used multiobjective reinforcement learning algorithms against a set of benchmarks. First, we describe a methodology that was used in this paper. Then, we carefully describe the details and properties of the proposed problems and how those properties influence the behavior of tested algorithms. We also introduce a testing framework that will significantly improve future empirical comparisons of multiobjective reinforcement learning algorithms. We hope this testing environment eventually becomes a central repository of test problems and algorithms The empirical results clearly identify features of the test problems which impact on the performance of each algorithm, demonstrating the utility of empirical testing of algorithms on problems with known characteristics. © 2012 Springer-Verlag.

- Description: While social media is a new and exciting technology, it has the potential to be misused by organized crime groups and individuals involved in the illicit drugs trade. In particular, social media provides a means to create new marketing and distribution opportunities to a global marketplace, often exploiting jurisdictional gaps between buyer and seller. The sheer volume of postings presents investigational barriers, but the platform is amenable to the partial automation of open source intelligence. This paper presents a new methodology for automating social media data, and presents two pilot studies into its use for detecting marketing and distribution of illicit drugs targeted at Australians. Key technical challenges are identified, and the policy implications of the ease of access to illicit drugs are discussed. © 2012 Springer-Verlag.

- Description: Since achieving Independence in 1957, Malaysia has experienced three recessions, each of which emanated from different sources of vulnerability. This paper analyses the policy response to economic crisis in particular, the role of the New Economic Policy (NEP) which was introduced in 1970 and which remains in force today. It concludes that in spite of the diversity in the proximate causes of the crises, the policy response was consistent and sought to ensure that NEP objectives were paramount and the vested interest that had emerged as a result of the NEP and which were linked to the ruling party were preserved.

- Description: Preserved fodder is a key component in modern agricultural practice. Hay bales are commonly provisioned for livestock. Unfortunately this is also a significant source of new weed infestations, including those of noxious species. Because hay bales may be of a low absolute value the usual approaches for weed control, for example herbicide treatment, may be expensive to apply and therefore not justified by the expected economic returns for this commodity. The methods of detecting weed seeds in bales that have been employed to date suffer from several deficiencies. These include the inefficiently long time needed for testing, loss of the commodity by overly destructive sampling methods and a serious potential for a lack of ecological representation for the presence of weeds. It is proposed that an alternative method, which is both potentially more rapid and more ecologically representative for detecting the presence of the seeds of noxious weeds in hay bales should be devised.

- Description: In Australia, all states and territories in Australia have maintained their own and separate set of laws for regulating health and safety. The difference has been more pronounced in the mining sector. The main reason for maintaining these separate regimes in mining has been based on an old-age argument that the hazards, culture and circumstances of the mining industry are somewhat different to those existent in other industries. As a result there are at least three different structures of the health and safety law in Australia. In recent years, however, there has been push by industry and government to drive some consistency and harmonization in regulating health and safety. To address this disparity the Federal Government has, in consultation with the states and territories, developed and issued the Model Work Health and Safety Act (WHSA) and the Model Work Health and Safety Regulations (WHSR) which is expected to become a uniform set of health and safety laws for the country. For the mining sector, a draft set of Regulations and Codes of Practice aimed at harmonizing health and safety has been issued. It is expected this will provide the country’s first ever set of standards and benchmarks for the mining sector. This paper compares and contrasts the existing and the proposed set of laws in the three states of Victoria, Queensland and Western Australia. It concludes with a discussion on what the proposed laws mean for managing risks associated with ventilation in underground mining
