ItemFour Melbourne Architects (1979): The Creation of Contemporary Perceptions for Australian Architecture(SAHANZ, 2022)In 1979, Peter Corrigan conceived the idea for the ‘Four Melbourne Architects’ exhibition to be held at South Yarra’s Powell Street Gallery. Corrigan led the charge to draw a line between a new generation of architectural practitioners with a fresh design agenda and the conservative practices represented by the Royal Australian Institute of Architects (RAIA). This exhibition, along with the establishment of the Half Time Club and the launch of Transition Magazine, provided platforms for a lively and vigorous profession. The ‘Four Melbourne Architects’—Greg Burgess, Peter Crone, Norman Day and Edmond and Corrigan—were diverse in their approach to architectural design yet shared common concerns of the post-Whitlam generation. The research for this paper examines the documentation between the four architects as they prepared their exhibition, recording the projects exhibited, along with critical reviews of the exhibition. Interviews have been undertaken with the surviving architects involved and people who attended the exhibition. Four Melbourne Architects was the first of many exhibitions during that period, which became one of many vehicles for public engagement with early postmodernism and those creating it, where collaboration, inclusion, and connectivity informed designers. That process activated a search for a contemporary Australian identity leading to the development of the ‘Melbourne School’.

The results from both techniques are compared and discussed. Identification will assist with the long-term management and storage of these polymer-based artefacts. Evaluation of these two sampling techniques included whether the physical characteristics and polymer type of the artefacts favoured the use of one technique over the other. The inherent challenges of archaeological artefacts such as cataloguing conventions, awkwardly shaped fragments and soil encrustations complicated the analysis. Of the 270 samples analysed, 67% were identified as containing ten different types of polymers, with the remaining 33% consisting of unidentified polymers, encrusted polymers in which only soil bands or other materials such as glass were identified. Although reflectance achieved better results for certain types of artefacts, it also revealed limitations. The identified polymers are compatible with the proposed occupation of the site from 1852 to the 1970s.

ItemRadical nephrectomy with caval tumor thrombectomy: An Australian experience(Canadian Urological Association, 2022)Introduction: Inferior vena cava (IVC) tumor thrombus is seen in up to 10% of renal cell carcinoma (RCC) and greatly complicates surgical management. We aimed to assess perioperative morbidity and longterm oncological outcomes after radical nephrectomy with caval tumor thrombectomy. Methods: This was a retrospective review of radical nephrectomy with caval tumor thrombectomy from 2011–2021. Continuous variables were reported as median (range). Kaplan-Meier survival curves were compared using the log-rank test. Results: We identified 22 patients; 15 (68.2%) were male and the median age was 63.5 years (34–75). There were three (13.6%) level III and eight (36.4%) level IV tumor thrombi. RCC size was 11.2 cm (2.7–21.0), with 13 (59.1%) right-sided. Nine (40.9%) patients had metastatic disease. Operative time was nine hours (5–18.8); seven (31.8) cases were performed emergently and nine (40.9%) underwent cardiopulmonary bypass. One (4.5%) patient died intraoperatively and four (18.2%) died in-hospital. Length of stay was 12.5 days (5–66) and 9 (40.9%) patients experienced Clavien-Dindo IV complications. Nineteen (86.4%) tumors were of clear-cell variant and 17 (77.3%) had positive margins. Excluding in-hospital deaths, median followup was 20 months (4–65). Five (27.8%) patients received adjuvant therapy and cancer recurrence occurred in six (33.3%). Overall survival (OS) was 66.7% (n=12) over a duration of 17 months (4–65) and recurrence-free survival (RFS) was 50% (n=9) over seven months (4–65). Time-to-recurrence and time-to-death were 9.5 months (2–19) and 13.5 months (1–33), respectively. On survival analysis, there were significant differences in OS (p=0.006) and RFS (p=0.006) with regards to metastatic status. Tumor thrombus level showed a difference in RFS only (p=0.006). Cardiopulmonary bypass was not predictive of OS (p=0.54) or RFS (p=0.82). Conclusions: Although radical nephrectomy with caval tumor thrombectomy is associated with significant morbidity and mortality, it remains an effective procedure in the treatment of advanced RCC.

ItemUsefulness of data analytics in Smart Villages development(Smart Villages Lab, The University of Melbounre, 2022-12-20)With over 40% global population still live in rural with many under extreme poor conditions, effective management of resources for supporting the development is crucial. One of the key considerations in effective management is need-based and context specific intervention planning incorporating bottom-up information flow. Traditional top-down approaches in planning and development are considered not only wasteful but also irrelevant for transforming rural communities keeping the value, culture, heritage at the core of the development cycle. In the bottom up planning, empirical data at the grassroots level activities play a pivotal role. In this research, significance of the data-driven planning coupled with the strong data-analytics is demonstrated as one of the most critical elements supporting the planning and development of rural communities under the auspice of Smart Villages. Based on a case study conducted across 37 villages in the river island Majuli in Assam located in the north eastern part of India, the research highlights the functionalities and efficacies of a Smart Data Platform used for evaluating real-time data analytics and supporting context specific planning and development of a large area comprising 2300 plus households. The concept is further highlighted to signify the need for central data-centric Research and Development center for supporting policy making within the public governance.

ItemNo Preview AvailableApplying empirical learning progressions for a holistic approach to evidence-based education: SWANS/ABLES(Australian Council for Educational Research, 2021-08)Learning progressions have become an increasing topic of interest for researchers, educational organisations and schools as they can describe the expected pathway of learning within a content area to allow for targeted teaching and learning at all levels of ability. However, there is substantial variation in how learning progressions are developed and to what extent teachers can use them to inform their practices. The ABLES/SWANS tools (Students with Additional Needs/Abilities Based Learning and Education Support) are an example of how an empirical learning progression can be applied to support teachers’ ability to not only target teaching to a student’s zone of proximal development (Vygotsky, 1978), but also to plan, assess, and report on learning. Across Australia, these tools are used to help of thousands of teachers of students with disability to make evidence-based teaching and learning decisions and demonstrate the impact of their work with students. This approach, which scaffolds student achievement towards goals informed by an empirical learning progression, combined with reflective teaching practices, can help teachers to develop their capacity as professionals and provide the most effective teaching and learning for every student, regardless of the presence of disability or additional learning need.

ItemNo Preview AvailablePrescribing oxygen: An audit of prescribing and delivery practices at two tertiary hospitals in Melbourne, Australia(Wiley Online Library, 2021)Background and Aims: Over-oxygenation in COPD patients can result in adverse outcomes. The use of specific oxygen saturation targets in COPD has been associated with less acidosis, a lower requirement for assisted ventilation, and reduced mortality. Our study reviews current practices of both oxygen prescription and delivery for patients admitted at two tertiary hospitals with an exacerbation of COPD. Methods: This retrospective audit included all admissions at two tertiary hospitals with a primary diagnosis of exacerbation of COPD over 6 months (April to September 2020). Medical records were reviewed to determine how many had documented target SpO2 ranges and how concordant these were with the Thoracic Society of Australia and New Zealand guidelines (SpO2 range 88% to 92% in COPD). For those with documented SpO2 ranges, we determined the percentage of recorded SpO2 levels that were below, above and within the target range. Results: 312 admissions for exacerbation of COPD were reviewed. Target SpO2 goals were documented for 57% of admissions (N=178), of which 77% (N=137) were consistent with current guidelines. Of those with a documented SpO2 range, only 75.4% of recorded SpO2 readings were within range, with 2.3% falling below and 22.3% above range. Conclusions: Our results highlight underutilisation of SpO2 targets in patients with COPD, as well as frequent over-oxygenation despite documented targets.

ItemBarbara van den Broek. Contributions to the Disciplines of Landscape Architecture, Town Planning and Architecture(SAHANZ, 2022)Barbara van den Broek (1932-2001) trained as an architect in Auckland, New Zealand before moving to Brisbane with her husband and fellow architect Joop, where they established an architectural practice. van den Broek went on to run an office as a sole practitioner and took on architecture and landscape architecture projects. Over the course of her career she completed post-graduate diplomas in Town and Country Planning, Landscape Architecture and Education, and a Master of Science – Environmental Studies, and collaborated on a number of key projects in Queensland and Papua New Guinea (PNG). Our paper will build an account of her career. In assessing the significance of her contribution to landscape architecture, planning and architecture in Australasia, it will bring a number of other spheres into the frame: conservation and Australia’s environment movement; landscape design and the bush garden; and van den Broek’s personal development that included artistic expression, single parenthood, teaching, and the navigation of male-dominated professional environments to develop a practice that contributed to town planning projects in cities across Australia, and made significant contributions to landscape projects in Queensland and PNG.

ItemNo Preview AvailableInnovative composite structural systems for modular tall buildings(https://www.compositeconstructionix.com/, 2021)Modular or offsite construction is believed to shape the future of the construction industry as it possesses significant benefits over traditional onsite construction methods. However, most of its application are limited to steel or concrete buildings. Although steel-concrete composite structural system has many merits over the steel and concrete systems, its application in modular buildings is very limited. This paper explores recent developments of composite systems for modular high-rise buildings. They include modular units for resisting vertical gravity loads and lateral structural systems for resisting horizontal forces from wind and earthquake loadings and progressive collapse due to accidental loads such as fire, explosions and impact. Various inter-module joining methods developed in the literature will also be reviewed. Finally, a case study of the most efficient connection is presented to explore its applicability to high-rise modular buildings.

ItemA Transferable Technique for Detecting and Localising Segments of Repeating Patterns in Time series(IEEE, 2021)In time series data, consecutively repeated patterns occur in many applications, including activity recognition from wearable sensors. Repeating patterns may vary over time and present in various shapes and sizes, which makes their detection a challenging problem. We develop a novel technique, RP-Mask, that can detect and localise segments of consecutively repeated patterns, without prior knowledge about the shape and length of the repeats. Our technique represents time series using recurrence plots (RP), a method for visualising repetition in time series. We identify two key features of recurrence plots-checkerboard patterns and vertical/horizontal lines marking the start and end of checkerboard patterns. We use object recognition on RP images to detect and localise the checkerboard patterns, which are mapped to the segments of consecutively repeating patterns on the underlying time series. Since the collection and labeling of a real world dataset that exhibits all possible variations of a repetition is prohibitive, we demonstrate that our model is able to effectively learn from synthetically curated data and perform equally effective on a real world dataset, while it is noise tolerant. We compare our method to a number of state-of-the-art techniques and show that our method outperforms the state of the art both when trained using real activity recognition and synthetic data.

ItemRelationships Between Local Intrinsic Dimensionality and Tail Entropy(SPRINGER INTERNATIONAL PUBLISHING AG, 2021)The local intrinsic dimensionality (LID) model assesses the complexity of data within the vicinity of a query point, through the growth rate of the probability measure within an expanding neighborhood. In this paper, we show how LID is asymptotically related to the entropy of the lower tail of the distribution of distances from the query. We establish tight relationships for cumulative Shannon entropy, entropy power, and their generalized Tsallis entropy variants, all with the potential for serving as the basis for new estimators of LID, or as substitutes for LID-based characterization and feature representations in classification and other learning contexts.
