Abstract:
Percy Rollo Brett OBE (11 November 1923 to 8 August 2022) was a highly respected head of the PMG/APO (later Telecom Australia/Telstra) Research Laboratories between 1964 and 1975. He was promoted to Head of Planning for Telecom Australia in July 1975, and then State Manager, Victoria for that organization in 1980–1983. Rollo’s achievements as Director of the Research Laboratories included building links with Australian universities to strengthen the Laboratories’ expertise in longer term research, and masterminding the Laboratories’ move from six different sites in central Melbourne to a single site, in purpose-designed buildings in Clayton, opposite Monash University’s main campus. In the early 1970s, he used the expertise he gained as Chairman of the Telecommunications and Electronics Standards Committee of the Standards Association of Australia to lead the Australian Post Office’s conversion of all its standards to metric. Upon retirement in 1983 he was awarded the OBE.

Abstract:
Abstract Fog events occur at Melbourne Airport, Melbourne, Victoria, Australia, approximately 12 times each year. Unforecast events are costly to the aviation industry, cause disruption, and are a safety risk. Thus, there is a need to improve operational fog forecasting. However, fog events are difficult to forecast because of the complexity of the physical processes and the impact of local geography and weather elements. Bayesian networks (BNs) are a probabilistic reasoning tool widely used for prediction, diagnosis, and risk assessment in a range of application domains. Several BNs for probabilistic weather prediction have been previously reported, but to date none have included an explicit forecast decision component and none have been used for operational weather forecasting. A Bayesian decision network [Bayesian Objective Fog Forecast Information Network (BOFFIN)] has been developed for fog forecasting at Melbourne Airport based on 34 years’ worth of data (1972–2005). Parameters were calibrated to ensure that the network had equivalent or better performance to prior operational forecast methods, which led to its adoption as an operational decision support tool. The current study was undertaken to evaluate the operational use of the network by forecasters over an 8-yr period (2006–13). This evaluation shows significantly improved forecasting accuracy by the forecasters using the network, as compared with previous years. BOFFIN-Melbourne has been accepted by forecasters because of its skill, visualization, and explanation facilities, and because it offers forecasters control over inputs where a predictor is considered unreliable.

Abstract:
IntroductionThe ambulance clinical triage-for acute stroke treatment (ACT-FAST) algorithm is a severity based 3-step paramedic triage tool for pre-hospital recognition of large vessel occlusion (LVO), designed to improve specificity and paramedic assessment reliability compared to existing triage scales. ACT-FAST sequentially assesses 1. Unilateral arm fall to stretcher <10 s; 2a. Severe language disturbance (right arm weak), or 2b. Severe gaze deviation/hemi-neglect assessed by shoulder tap (left arm weak); 3. Clinical eligibility questions. We present the results of the ongoing Ambulance Victoria paramedic validation study.MethodsAmbulance Victoria paramedics assessed ACT-FAST in all suspected stroke patients pre-hospital in metropolitan Melbourne, Australia, and in the Royal Melbourne Hospital Emergency Department since July 2017. Algorithm results were validated against a comparator of ICA/M1 occlusion on CT-angiography with NIHSS ≥6 (Class 1 indications for endovascular thrombectomy).ResultsData were available from n=119 assessments (ED n=68, pre-hospital n=51). Patient diagnoses were LVO n=20 (15.6%), non-LVO infarcts n=45 (38.5%), ICH n=10 (8.3%) and no stroke on imaging n=44 (37.6%). ACT-FAST showed 85% sensitivity, 88.9% specificity, 60.7% (72% excluding ICH) positive predictive value and 96.7% negative predictive value for LVO. Of 10 false-positives, 4 received thrombectomy for non-Class 1 indications (basilar/M2 occlusions/cervical dissection), 3 were ICH, and 1 was tumour. Three false-negatives were LVO with milder syndromes.DiscussionThe ongoing ACT-FAST algorithm validation study shows high accuracy for clinical recognition of LVO. The streamlined algorithmic approach with just two examination items provides a more practical option for implementation in large emergency service networks. Accurate pre-hospital recognition of LVO will allow bypass to endovascular centres and early activation of neuro-intervention services to expedite endovascular thrombectomy.

Abstract:
As in Australia school education is the responsibility of State Governments, this article will consider two computer systems in the Australian State of Victoria. The article takes a socio-technical stance to examine two computer systems currently in use in schools in Victoria: CASES21 and the Ultranet. After describing these systems, the article makes use of actor-network theory to explore the actors involved in their creation, development, implementation and use (or in one case non-use), and the networks they established in doing so. It looks at the associations involving both the human and non-human actors and how these contributed to successful adoption and use of these systems. A comparison of two systems within the same organisational environment allows a unique perspective on the formation of networks. The ANT approach permits an understanding of the difference in adoption where very few factors differ between the cases.

Abstract:
There are still comparatively few investigations which look, in detail, at who the rural English emigrants of the nineteenth century were, the villages and communities they came from, and the rural kinship and recruitment networks which supported their decision. Deficiencies in the published statistical returns, and the fact that good historical data about the English is mainly concerned with the first half of the nineteenth century, have not helped further emigration research. This has led to the situation whereby English emigration has been largely disregarded by some historians or, because British governments were initially preoccupied with emigration as a means of relieving distress, interpretations have tended to rest, precariously, on generalisations that English emigration was the product of economic dislocation. The dearth of historical studies is most striking if we note that, between 1853 and 1930, the English contributed over nine million emigrants to the European diaspora, that numerically they dominated Britain's non-Irish (English, Scottish and Welsh) emigration to most of the destinations available to them, and that the English have proved to be some of the most mobile and persistent of all international migrants.

Abstract:
This research demonstrates the ways in which computer games can provide a context for effective skill acquisition and knowledge transfer in vocational education and training (VET). In particular, it focuses on how they might increase learner engagement in theoretical subjects. The study examined the rationale behind making a pedagogical shift from content delivery to designing experience. It further investigated whether games-based learning has the potential to add meaning and relevance to VET outcomes through considering the impact of the game components of narrative, fun and gameplay in a games-based learning activity system. The study utilised a Design Based Research methodology, within an Activity Theoretical framework.

Vo, Nguyen. "A New Conceptual Automated Property Valuation Model for Residential Housing Market." Thesis, 2014. https://vuir.vu.edu.au/25793/.

Full text
Abstract:
Property market not only plays a major role in the Australian real estate economy but also holds a large portion of the country’s overall economic activities. In the state of Victoria, Australia alone, residential property values surpassed one trillion dollars in 2012. A typical weekend property auctions in Victoria could see tens of millions of dollars change hands. Residential property evaluation is important to banks or mortgage lenders, real-estates, policy-makers, home buyers and those involved in the housing industry. A tool which can predict prices is essential to the housing market. Residential properties in Victoria are re-valued manually every two years by the Department of Sustainability and Environment, Victoria, Australia (DSE) with up to 30%± uncertainty of the market values. Municipal councils use the values established by DSE to determine property rates and land tax liabilities. According to rpdata.com, there are currently five types of Automated Valuation Models (AVMs) used in residential property valuation in Australia: sales comparison approach, cost approach, hedonic, income capitalisation approach and price indexation. The calculation backbone for these AVMs is still based on traditional statistics approach. At the time of writing this thesis, only a handful of researchers in the world have used Artificial Neural Network (ANN) in AVM to estimate residential property prices. In this research work, a Conceptual Automated Property Valuation Model (CAPVM) using ANNs was proposed to evaluate residential property price. The ultimate goal was to produce long-term house price forecast for urban Victoria. The CAPVM was first optimised and then its residential property price forecast capability was investigated. Optimisation of CAPVM was achieved by determining the best number of the hidden layers, the hidden neurons and the input variables, and finding the best value of training error threshold. CAPVM was excellent in predicting 86.39% of residential property prices within the accuracy margin of 10%± error of the actual sale price, a better performance than DSE’s manual valuations and National Australia Bank’s published figures. It successfully modelled the annual changes in residential property prices for hard to predict periods 2007-2008 during the global financial crisis and 2010-2012 residential property boom when the interest rates were on a downwards trend. CAPVM also outperformed the prediction performance of multiple regression analysis.

Abstract:
This chapter describes some aspects of the development of VICNET, an assemblage of computers, cables, modems, people, texts, libraries, buildings, dreams and images. It is a system that is difficult to characterise, it is dynamic both in geographical and ontological scope, size and usage. I have attempted to capture some of its nature through the use of several vignettes that may give the reader a small insight into parts of its being, then using some of the techniques and explanatory and exploratory mechanisms available from the field of science studies such as heterogeneous engineering and Actor Network Theory (ANT), I reveal some of the ways that VICNET came into existence. Many computer systems are undergoing continual evolution and it is extremely difficult to discern their configuration and what objects have agency at any given point in time; they can be thought of as open systems as described by Hewitt and de Jong (1984). VICNET, an Internet information provider established in 1994 as a joint venture between the State Library of Victoria and Royal Melbourne Institute of Technology, is one such system; it is being used by a large number of people and public libraries, yet simultaneously it is evolving and being shaped by the technology, the users and the environment of which it is part. Consider the system, VICNET as it is called, as a node of a much larger network. I have attempted to unfold this node to reveal the social and technical worlds contained therein, but I also fold the VICNET node in itself so that it becomes part of a much larger sociotechnical system – the Internet. This process of folding I refer to as a topological transformation and it is by studying transformations of this type that may help us understand how open systems come into being and evolve. In what follows, I provide a brief background to VICNET and the data collection method I used. Next, I discuss some the analytical techniques that are available for those who wish to study the development of technological systems. Following this all-too-brief comment I then present a selection of vignettes that show the varied nature of this socio-technical system. Presenting these then allows me to develop further the idea of social topologies introduced in the section on analytical techniques. In the final section there is some discussion as to why this way of looking at socio-technical systems may be useful.

Abstract:
Australia’s Joseph Gutnick is a billionaire, a diamond and gold miner, a political player, a philanthropist, and a rabbi. On October 20, 2000, Gutnick awoke in Victoria to find himself accused of tax evasion and money laundering by the American business magazine Barron’s. The article, “UnHoly Gains,” suggested that Gutnick had engaged in shady dealings with Nachum Goldberg, a Melbourne money launderer jailed in 2000 for washing AU$42 million in used notes through a bogus Israeli charity. Gutnick read the story, not in the print version of Barron’s but on the online version of its sister publication, “wsj.com,” a website on a server physically located in New Jersey. Gutnick was not the only Australian to read the story. Approximately seventeen hundred Australians subscribed to wsj.com, including many Australian business and finance leaders. An enraged Gutnick vehemently denied the illicit association with Goldberg. To protect his reputation, he sued Dow Jones & Company—the parent company of both Barron’s and the Wall Street Journal—in an Australian court, taking advantage of tough Australian libel laws unleavened by the U.S. First Amendment. The legal arguments in the Gutnick case mirrored those in the Yahoo litigation in France a few years earlier. Dow Jones argued that Australian courts were legally powerless (or “without jurisdiction”) to rule on the legality of information on a computer in the United States, even if it appeared in Australia. The Australian High Court, like the court in France, disagreed. For material published on the Internet, it stated, the place where the person downloads the material “will be the place where the tort of defamation is committed.” Within two years of this decision, Dow Jones agreed to pay Gutnick AU$180,000 in damages and AU$400,000 in legal fees to settle the case. It also issued this retraction: “Barron’s has no reason to believe Mr. Gutnick was ever a customer of Mr. Goldberg, and has no reason to believe that Mr. Gutnick was a money laundering customer of, or had any criminal or other improper relationship with, Mr. Goldberg.”

Abstract:
The chapter poses questions about the goal of building community through the creation of local networks, using the example of an entrepreneurial scheme to create a resident-run computer network in the Atherton Gardens high-rise housing estate in inner Melbourne, Australia. The scheme stems from a social partnership between a not-for-profit organisation, government and community groups; the aim is to enable residents to re-enter training, employment and community activities. The first stage of the paper places the scheme in the context of broader debates on the digital divide, information poverty and social capital, drawing out existing problems in the field. The authors discuss the problems of tracking the social impact of computer networks on ‘communities’, especially where there is a great diversity of interest and allegiance. The Atherton Gardens Reach for the Clouds initiative exemplifies such difficulties. The chapter argues that enthusiasm for this innovative scheme should be balanced by caution in using the vocabulary of social capital and community building. It cannot be assumed that online communication will build social connection off-line, given the diversity of interests, groups and allegiances within groups. This argument is made drawing on the initial stage of survey-based research on Atherton Gardens residents’ patterns of computer and media use, of employment and training, social connectedness, use of social services and experience of living on the estate. The authors conclude by reflecting on the broader implications of the case study for research on the social impact of computer networks on multiethnic populations with diverse needs, interests and allegiances.

Victoria University offers a Computer Science degree in Hong Kong. The Hong Kong program matches the one in Melbourne, but both the content coverage and the delivery model of the Hong Kong program are affected by expectations and demands of the Hong Kong government and students. The paper outlines challenges, legislative, cultural, quality, time and distance that shaped the program delivery model. It examines the social construction of the program curriculum, and identifies cultural factors that have had most impact in modifying the program. The paper regards distance education as an informing discipline and discusses the program delivery model in terms of the Informing Science Framework. It uses a Project subject to illustrate the model and rationale behind it, and comments on suitability of various multimedia components as program delivery vehicles. The paper concludes by considering the implications of the Hong Kong program experience on future directions in distance education.

EXPERIMENTAL STUDY OF MICROWAVE SLOW WAVE COMB AND CERAMIC APPLICATORS FOR SOIL TREATMENT AT FREQUENCY 2.45 GHZ. G. Brodie and G. Torgovnikov University of Melbourne, 4 Water St, Creswick, Victoria 3363, Australia; e-mail: grigori@unimelb.edu.au Keywords: ceramic applicator, comb applicator, microwave, slow wave, soil microwave treatment In many cases in industry it is required to heat or treat surface layers of different material (soil, timber, concrete, plastics and so on) with microwaves (MW). Traditional MW irradiators (antennas) cannot provide heating only in the surface areas and energy penetrates deep into the material, where it decays exponentially due to normal attenuation. Therefore, energy losses, if a heating depth of 20 - 40 mm (for example to heat soil for killing weed seeds) is all that is required, are very significant. Therefore, it is required to develop special MW applicators for surface treatment to increase process efficiency. To address this problem, a slow wave (which is sometimes called a "surface wave" applicator) comb and ceramic structures, was studied. The main property of slow waves is that the energy concentration is very near impedance electrode – comb or ceramic plate surface. Previously, slow wave structures were used mostly as delay lines and as interaction circuits in MW vacuum devices, and their properties were explored only for these specific applications. The work objectives of this study were: design slow wave, ceramic and comb structure applicators for soil treatment at frequency 2.45 GHz;experimentally study the energy distribution from slow wave applicators in the soil;study of opportunities to use slow wave structures for surface soil layer heating; andrecommendations for practical use of new slow wave applicators. Comb and ceramic slab applicators for frequency 2.45 GHz operation were designed for the soil treatment on the bases of theoretical studies and computer modelling. The comb applicator was made from aluminium and the ceramic slab applicator was made from alumina (DC=9.8, loss tangent=0.0002). A 30 kW (2.45 GHz) microwave generator was used for experiments. Containers with soil were placed on the applicator surface. An auto tuner was used in MW system to provided good impedance matching of the generator and applicators (with soil on top). This resulted in practically no power reflection. The soil “Potting Mix Hortico”, with moisture content range 32-174% and density range 590-1070 kg/m3, was used for the experiments. Energy distribution in the soil was determined by temperature measuring in the soil using thermocouples, after MW heating. Distribution of temperature measuring points covered the whole volume of the soil along and across the applicator. Results of the experiments showed that the comb applicator provides maximum energy release in soil in the central vertical plane. The ceramic alumina applicator forms two temperature maximums in two vertical planes at a distance of about 40 mm from the central applicator plane and a minimum in the applicator central plane. The ceramic applicator provides better uniformity of energy distribution across the width of the applicator due to the two temperature maximums. It reduces overheating of the soil surface and energy losses. The depth of energy penetration provided by ceramic applicator is lower compared with the comb applicator. It means that the ceramic applicator provides better energy localization and more energy absorption in the soil surface layers compared with the comb applicator. To provide better uniformity of energy distribution across the ceramic applicator it is recommended to use ceramics with higher dielectric constants, such as in the range of 15-25, which will allow more energy to be released closer to the applicator surface. It will increase efficiency of MW energy use. The ceramic applicator is more effective for MW treatment of the soil surface areas and is recommended for practical use in machines for thermal treatment and sterilization of surface layers of the soil and other materials.
