ItemNo Preview AvailableObjects of fame(The Grainger Museum, University of Melbourne and The Victorian Arts Centre Trust, 2018)Melbourne produced two international stars of classical music – Dame Nellie Melba and Percy Grainger – in the decades surrounding Federation. Adopting a name in honour of her home town, Nellie Melba made her professional debut in 1887 and became hailed as the greatest opera singer of her time. Percy Grainger was a child prodigy who forged a career of pianistic brilliance and musical innovation as the new century unfolded. Each conquered the world’s great stages, enjoyed royal approbation and public fascination. The musical talents of Melba and Grainger, who had both family and professional connections, were matched only by the fame they engendered. Stampeding their way into popular consciousness as early media-assisted celebrities, they created rich intellectual and material legacies. Objects of Fame showcased these two extraordinary Australians, drawing on objects from Arts Centre Melbourne’s Australian Performing Arts Collection (APAC), and the Grainger Museum. With 221 collection objects on display. this exhibition also offered opportunities to consider fame in the context of today’s technology-focused culture that allows performers to become ‘famous’ in ways that Grainger and Melba could never have conceived.

ItemThe Living Instruments Project: Sharing sounds of heritage instruments in the Grainger Museum Collection(Australasian Sound Recordings Association, 2022-01-01)The Living Instruments project aims to digitally preserve the sound of the fragile Grainger instrument collection, but it also presents a way of transforming the relationship between musical artefacts and their cultural value with a diverse group of people including contemporary makers. The Living Instruments project emerged in the nexus of teaching, learning, and research activity in the Faculty of Fine Arts and Music, and the stewardship of Percy Grainger’s historic instruments held in the Grainger Museum, at the University of Melbourne. It aims to provide greater research opportunities and creative engagement with the instruments through an interactive platform of sonic resources. This paper provides an overview of the stimulus for the Living Instruments project and shares the stages of the research journey and public outcomes.

ItemCompetitive Triplet Formation and Recombination in Crystalline Films of Perylenediimide Derivatives: Implications for Singlet Fission(AMER CHEMICAL SOC, 2020-05-28)Developing photostable compounds that undergo quantitative singlet fission (SF) is a key challenge. As SF necessitates electron transfer between neighboring molecules, the SF rate is highly sensitive to intermolecular coupling in the solid state. We investigate SF in thin films for a series of perylenediimide (PDI) molecules. By adding different substituents at the imide positions, the packing of the molecules in the solid state can be changed. The relationship between SF parameters and the stacked geometry in PDI films is investigated, with two-electron direct coupling found to be the main SF mechanism. Time-resolved emission and transient absorption data show that all of the PDI films undergo SF although with different rates and yields varying from 35 to 200%. The results show that PDI1 and 2, which are stacked PDI pairs twisted out of alignment along the highest occupied molecular orbital to lowest unoccupied molecular orbital transition, exhibit faster and more efficient SF up to 200% yield. We demonstrate that both triplet formation and decay rates are highly sensitive to the ordering of the molecules within a film. The results of this study will assist in the design of optimized structures with a fast SF rate and low recombination rate that are required for useful light harvesting applications.

Itemplyranges: a grammar of genomic data transformation(BMC, 2019-01-04)Bioconductor is a widely used R-based platform for genomics, but its host of complex genomic data structures places a cognitive burden on the user. For most tasks, the GRanges object would suffice, but there are gaps in the API that prevent its general use. By recognizing that the GRanges class follows "tidy" data principles, we create a grammar of genomic data transformation, defining verbs for performing actions on and between genomic interval data and providing a way of performing common data analysis tasks through a coherent interface to existing Bioconductor infrastructure. We implement this grammar as a Bioconductor/R package called plyranges.

ItemA preliminary investigation into the influence of archaeological material on the yellowing of polyethylene storage bags(Routledge, 2021)Concerns around the degradation of plastics have been part of conservation discourse for decades. The spotlight is usually on art and objects, and conservation and display materials, however it could be argued that a significant volume of the plastics in museums is associated with storage bags. This study asked whether the condition of plastic storage bags might be influenced by what is stored inside them. If specific materials can be identified as more likely to affect plastic degradation, museums may have a lead-indicator for efficiently monitoring storage risks. This case study developed a methodology for applying multivariate analysis to collected data to answer this question. A subset of polyethylene self-seal bags used to pack archaeological material from the ‘Casselden Place’ assemblage at Museums Victoria was evaluated. Objective data were combined with subjective assessment of bag degradation features gathered during a collection survey and interrogated using multivariate statistical analysis. Results indicate (1) different levels of yellowing are associated with particular plastic bag stocks and (2) ceramic, slate and tile finds are more likely than other materials to be contained within yellower bags. The research points to future enquiry and demonstrates this methodology shows promise for extension to other large cultural datasets.

ItemNo Preview AvailableThe Women’s Healthy Ageing Project: A pattern of cognitive decline after brain injury(Wiley, 2021-12)Abstract Background It is well recognised that damage sustained by traumatic brain injury (TBI) initiate injury mechanisms that continue to develop long after insult. Increasing evidence suggests TBI may lead to chronic cognitive decline and the development of dementia later in life. However, due to the low rate of TBI in the general community, there is a paucity of data on the impact of cognitive decline in community TBI. We examined longitudinal cognitive changes over a 12‐year period to determine if there was any relationship with community reported TBI. Method The Women’s Healthy Aging Project is an ongoing longitudinal cohort study of community‐dwelling Australian women. Assessments included an extensive range of measures, including neuropsychological testing of multiple cognitive domains and questions relating to head injury. In total, 110 women had complete neuropsychological testing at all three time points; from 2002, 2012 and 2014. Of these women, nine (aged 56‐65 in 2002) had a history of moderate to severe TBI. Composite cognitive scores were compared to 18 healthy controls randomly selected from the complete dataset individually matched for age, education, and APO4‐genotype. Analyses were conducted in five datasets drawn from the complete dataset and results were averaged. Result Median scores for executive function were similar for both the TBI group and healthy controls in 2002, lower in the TBI group by 2012 and this difference increased further in 2014. Median scores for verbal episodic memory were slightly lower in the TBI group than controls in 2002 and 2012, and this difference increased in 2014. Although this initial pilot study with small samples in mid‐aged healthy women did not show statistically significant results, the observed relationships were constant over the five datasets, warranting further exploration. Conclusion In our small pilot study, we observed greater rate of decline of both executive function and verbal episodic memory in women with a history of TBI. Findings warrant a need for larger studies to explore this relationship as it indicates that community‐based reported TBI may impact cognitive performance even in early ageing. Further work will continue to explore cognitive trajectories in women with a mean age 80 at next follow‐up.

ItemNo Preview AvailableA macro-element model for predicting the combined load behaviour of spudcan foundations in clay overlying sand(Thomas Telford Ltd., 2021-10-26)A macro-element model for predicting the load–displacement behaviour of a spudcan foundation in clay overlying sand when subjected to combined vertical, horizontal and moment loading is introduced. Observations from detailed drum centrifuge tests that measured the effect of the underlying sand layer on the foundation behaviour are combined with finite-element results and theoretical developments to derive the components of the model. The yield surface defined by the centrifuge test results suggests that as the spudcan nears the underlying sand layer, the absolute horizontal capacity remains relatively constant, while the vertical and moment capacities increase at approximately the same normalised rate. The model is demonstrated to accurately predict foundation behaviour by retrospectively simulating the experimental results. This macro-element model has the advantage that it can be integrated into the structural analyses of jack-up platforms required for site-specific assessments.

ItemNo Preview AvailableMetaphor-A workflow for streamlined assembly and binning of metagenomes.(Oxford University Press (OUP), 2022-12-28)Recent advances in bioinformatics and high-throughput sequencing have enabled the large-scale recovery of genomes from metagenomes. This has the potential to bring important insights as researchers can bypass cultivation and analyze genomes sourced directly from environmental samples. There are, however, technical challenges associated with this process, most notably the complexity of computational workflows required to process metagenomic data, which include dozens of bioinformatics software tools, each with their own set of customizable parameters that affect the final output of the workflow. At the core of these workflows are the processes of assembly-combining the short-input reads into longer, contiguous fragments (contigs)-and binning, clustering these contigs into individual genome bins. The limitations of assembly and binning algorithms also pose different challenges depending on the selected strategy to execute them. Both of these processes can be done for each sample separately or by pooling together multiple samples to leverage information from a combination of samples. Here we present Metaphor, a fully automated workflow for genome-resolved metagenomics (GRM). Metaphor differs from existing GRM workflows by offering flexible approaches for the assembly and binning of the input data and by combining multiple binning algorithms with a bin refinement step to achieve high-quality genome bins. Moreover, Metaphor generates reports to evaluate the performance of the workflow. We showcase the functionality of Metaphor on different synthetic datasets and the impact of available assembly and binning strategies on the final results.

ItemEncountering a Pedagogy of the World in a University Setting(Taylor & Francis, 2021)Taking up Biesta’s (2019) notion of a pedagogy of the world, we ask: How might participating in an arts-based educational program with/in a university enable young people from schools with low Index of Community Socio-Educational Advantage (ICSEA) values to encounter the world of higher education differently and become different in that encounter? This chapter comes from our engagement with empirical material generated during a (post)qualitative inquiry into the pedagogy of The Art of Engagement-a multi-arts studio program involving relational pedagogy and a/r/tography as curriculum located in SPACE, 1 whereby secondary school students from schools in less socio-educationally advantaged communities came together with undergraduate university students for a five-day intensive within a University of Melbourne breadth subject. The program’s rationale was to connect with secondary school arts students completing their schooling in lower ICSEA value schools 2 through the design of authentic university encounters with/in site, practices and communities. It welcomed the secondary school students into the world of our university and enhanced their capacity to “be at home” in this world, creating the conditions for considering and potentially living different post-school futures.

ItemScicurious as method: Learning from GLAM young people living in a pandemic about cultivating digital co-research-creation spaces that ignite curiosity and creativity(Bristol University Press, 2020-10-23)Could COVID-19, this unexpected crisis, act as a comma in a co-research-creation project to become a breathing space and not a full stop? Maybe this pause is a colon: the two different periods of the project (and life in general) on either side of the pandemic, equally important and dependent on each other for full meaning. In this chapter, we tell the story of how a co-research-creation event (the Sci Curious Project) unfolded before and during the COVID-19 pandemic; the lead-up to its irruption (St. Pierre, 1997) and then what came after. ‘Scicurious as method’ emerged out of the unexpected pause and recalibration of the project; a method that emphasizes the creation of research spaces that activate scicuriosity in situated practice. We understand scicuriosity as emerging from collaborative research-creation events that ignite curiosity and creativity. Scicurious as method is presented through an encounter with speculative fiction and scicurious zine travels. Scicurious as method has significant ethical implications, these reify the potential of co-designed speculative inquiries with creativity and curiosity at their heart. This is, in part, due to its contingency on cultivating digital co-research-creation spaces that enfold rather than eschew the analogue and highlight the joyous potential of a deeply situated, co-designed speculative inquiry; an inquiry with galleries, libraries, archives and museums (GLAM) young people living in a pandemic.
