ItemTell Touch – A digital health intervention for the Aged Care Sector: An evaluation pilot( 2022)This project reports on a pilot evaluation of Tell Touch - a digital communication application. The evaluation had two purposes. Firstly, the developers of Tell Touch wanted to understand the benefits and challenges of instigating a full evaluation of Tell Touch. Secondly, the effectiveness of Tell Touch as a communication platform for complaints and feedback handling in an Aged Care Home was examined from the perspective of the staff who use the application tool. Tell Touch was developed as a feedback and complaints application tool (app) for use in Aged Care Homes (ACHs). The objective of the app is to improve the quality of care provided to residents by facilitating ACHs to be more consumer-oriented and comply with or exceed the four requirements of the Aged Care Quality and Safety Commission (ACQ&SC) Standard 6. A review of the literature determined the Technology Adoption Model (TAM) as one of the most effective frameworks used in health care settings to assess the adoption of technology. The TAM has been validated in research as a conceptual model that can predict a substantial portion of the use or acceptance of IT health-related settings. Thus, the TAM was used to develop hypothesis to be explored using quantitative data. Qualitative data was collected to better understand the experience of ACH staff in using Tell Touch; specifically, to understand if Tell Touch was perceived as useful, and if Tell Touch satisfied the needs of ACH management for information that would improve services to residents and meet accreditation requirements. The data collected came from eight operational and top managers working in six ACHs across Victoria, and was collected over the period April to October 2022. Findings suggest a full evaluation of Tell Touch is feasible using the research design, tools and methods adopted in this project. Furthermore, early findings from this pilot evaluation indicate Tell Touch does meet the purposes for which it was developed; that is it is an effective IT communication platform for complaints and feedback handling in ACHs.

ItemEngaging Primary Girls in STEM: Best Practice Implementation & Gaps in Victorian Classrooms(Swinburne University of Technology, 2022-02-08)The case for increasing girls’ and women’s’ interest and uptake in STEM careers has been clearly outlined and resonated with educators, industry, and policy makers in Australia. It is recognised that primary school years are critical in harnessing and developing girls interests and enthusiasm for STEM activities and education. However, some primary school teachers lack the knowledge, capacity, and confidence to teach STEM, and that an overpopulated curriculum does not lend itself easily to integrating change and STEM approaches to teaching. This report is based on a review of current literature. A limited amount of published academic literature could be located that specifically addresses the intersection of primary school aged girls (approximately 5-11 years old) and STEM engagement. We found that more attention was paid to this topic by grey literature, mostly in the form of consultancy reports and reviews which were commissioned by government or industry. Findings from this review are reported below, with a focus given to everyday classroom practices within the current educational context. This report addresses one of our key project objectives: to curate and create free resources for use by teachers and parents within the current environment to assist the 'now to the future' state.

ItemEsports Spectatorship in Australia(Networked Society Institute, 2018)Esports – the organised, professional and spectated play of competitive digital games – has evolved into a massive global industry in the past decade. Boasting significant market value and broad global audience reach, esports is driven by modern highspeed internet infrastructure and live-streaming platforms like Twitch.tv. However, esports has yet to take hold as an industry in Australia, largely due to geographical isolation from major esports regions compounded by Australia’s traditionally lacklustre network infrastructure. Although the esports industry relies on various revenue streams, sponsorship and advertising deals provide the industry’s main source of funding. Teams, tournaments and esports organisations of various sizes are sponsored by major international companies like Intel, Samsung and Mercedes-Benz. This is unsurprising considering the global reach of esports. According to the ‘market intelligence’ firm Newzoo (2017), the esports audience in 2017 is estimated to be 385 million, with rough half of those being ‘enthusiasts’ and the other half ‘occasional viewers’. Furthermore, they estimate that the esports industry generated roughly US $696 million in revenue through ticket sales, media rights, game publisher fees, advertising and merchandise, sponsorship, media rights, in-game microtransactions, and betting in 2017. Newzoo estimates this amount to grow to US $906 million in 2018. Revenue growth for the esports industry has been significant, with current estimates pointing to a year-over-year growth of 41% in 2017, of which US$517 million is in advertising, sponsorship, and media rights (Newzoo 2017). While global industry reports are optimistic about the future of esports, the Australian esports scene is limited in comparison to overseas markets. In this report, we start by approximating the size of the esports market in Australia by comparing publicly available statistics and collecting a list of major global and Australian esports events. Secondly, we provide an overview of key Australian esports titles, explaining how they’re played as esports and their place within the Australian esports landscape. Thirdly, we explore the practice of spectating esports and discuss motivations behind esports spectatorship. We then present a preliminary study consisting of 18 semi-structured interviews with esports spectators regarding their engagement with and consumption of esports content. From our findings, we identify and detail three salient categories of non-exclusive esports spectator types: players, fans and recruits. We conclude with a summary of key changes in the Australia esports landscape during 2018 and important upcoming developments.

ItemTimestamp Repair for Business Process Event Logs( 2018-04-05)This paper contributes an approach for automatically correcting timestamp errors in business process execution logs. These errors are quite common in practice due to the logging granularity or the performance load of the logging system. Analyzing logs that have not been properly screened for such problems is likely to lead to wrong or misleading process insights. The proposed approach revolves around two techniques: one to reorder events with erroneous timestamps, the other to assign an estimated timestamp to each such event. The approach has been implemented in a software tool and extensively evaluated in different settings, using both synthetic and real-life logs. The experiments show that the approach significantly reduces the amount of incorrect timestamps, while the reordering of events scales well to large and complex datasets. The evaluation is complemented by a case study in the meat & livestock domain showing the usefulness of the approach in practice.

ItemBehavioural Quotients for Precision and Recall in Process Mining( 2018)The comparison of the languages of software systems, i.e., their behaviours in terms of specified executions, is a prerequisite for many applications, reaching from system validation through management of a system's evolution to conformance checking of observed and expected behaviour. If two systems are not language-equivalent, the quantification of behavioural differences enables conclusions on the extent of deviation. Such quantifications are commonly done in a relative manner: A quotient is defined over some measure of two languages, which have potentially been derived via algebraic operations. However, there exists no systematic approach for defining quotients and it is unclear which measures enable meaningful comparisons of systems having infinite behaviours. This paper introduces a framework for defining language quotients. We instantiate the framework with cardinality-based and entropy-based measures to handle finite and infinite behaviours, and prove important properties of the quotients. We demonstrate application of quotients in the field of process mining to capture precision and recall between a log of recorded system executions and a model of expected system executions. An experimental evaluation of the quotients using our open-source implementation demonstrates their feasibility and indicates that the quotients enable a monotonic assessment, unlike state-of-the-art measures in process mining.

ItemAnti-personnel landmine detection based on GPR and IR imaging: a review( 2006-04)Ground penetrating radar (GPR) and Infrared (IR) camera have become two established sensors for detecting buried anti-personnel mines (APM) which contain no or a little metal. This report reviews the detection techniques of APM using GPR and IR, and describes particular situations where each technique is feasible. We provide an analysis for fusion based detection and classification of APM. We discuss the GPR and IR data acquisition, signal processing and image processing methods. We also include a comparative study of these two sensors with respect to signal processing and target detection procedures. The report discusses the strengths and weaknesses of each of the sensors based on data capturing efficiency, overcoming environmental difficulties and sensor technology. Finally, we emphasize that a geometrical feature based sensor fusion, combining GPR and IR, for detection and classification of APM may be the most effective technique.
