Research outputs 2022 to 2026

Imagine being in a university that functions in a place-based culturally regenerative way. In this concept paper, the authors bring together theory, practice, and experience, in the service of transforming universities towards place-based cultural regeneration. At present, Australian universities operate using an economic philosophy of neoliberal corporatism characterised by hierarchical management strategies, competitive tendencies, patriarchal values, and discourse characterised by bifurcation or binary thinking. These features illustrate a worldview that is entangled with the meta crises of our times such as climate change, species loss, hatred/intolerance, and unfathomable violence. The authors consider ways of moving towards a place-based, Indigenous-informed, practical, …

The Somatechnics Of Journalism: Applying An Embodied Perspective To Enduring Issues In Journalism Studies, Laura Glitsos, Mark Deuze

Research outputs 2022 to 2026

This research applies Somatechnics to the study of journalism and contributes to an emergent epistemological “bodily turn” in the discipline of Journalism Studies. This is a turn toward the body, embodied experience, and the inevitable emotionality of journalism and the journalist as brought forth by Chantal Francoeur and Belinda Middleweek, among others. We invite journalism scholars (and practitioners) to understand journalists’ bodies as sophisticated organic technologies—and to subsequently understand how those bodies are further transmogrified by, and collapsed into, the ever-changing world of news media. We deploy a process of retheorising as a qualitative method in which researchers apply new …

Diverged Populations Admixture Bolsters Genetic Diversity Of A New Island Dibbler (Parantechinus Apicalis) Population, But Does Not Prevent Subsequent Loss Of Genetic Variation, Rujiporn Thavornkanlapachai, Harriet R. Mills, Kym Ottewell, Cathy Lambert, J. Anthony Friend, Daniel J. White, Zahra Aisya, W. Jason Kennington

Research outputs 2022 to 2026

Translocating individuals from multiple source populations is one way to bolster genetic variation and avoid inbreeding in newly established populations. However, mixing isolated populations, especially from islands, can potentially lead to outbreeding depression and/or assortative mating, which may limit interbreeding between source populations. Here, we investigated genetic consequences of mixing individuals from two island populations of the dibbler (Parantechinus apicalis) in an island translocation. Despite a high level of genetic divergence between the source populations (FST ranges 0.33–0.64), and significant differences in body size, individuals with different ancestries were able to successfully interbreed in captivity and in the wild. However, …

Predicting Early Hospital Readmissions For Diabetic Patients Using Machine Learning, Amanda Ferraz, Leonardo Oliveira

ICT

This project applies machine learning to predict whether diabetic patients will be readmitted to a hospital within 30 days of discharge. Early readmissions are a costly and critical issue in healthcare, often signalling gaps in post-discharge care and risk management. Diabetic patients face unfair high readmission rates compared to the general population. According to the CDC Diabetes Report Card 37.3 million people in the U.S. or 11.3% of the population had diabetes as of 2019 (CDC, 2021). Our goal here is to develop a binary classification model capable of flagging high risk patient (< 30-day readmission) based on their clinical, demographic, and administrative data. This lets healthcare institutions to take measures,

2020-Current year OA Pubs

Cervical cancer is preventable; however, it remains the leading cause of death in low- and middle-income countries (LMICs). Women with HIV (WWHs) have a sixfold higher risk of developing and dying from cervical cancer than women without HIV. Cervical cancer can be prevented by vaccination against high-risk human papillomaviruses (hrHPVs) and by screening for and treating precancer cervical lesions. While these preventive measures are routinely available to WWHs in developed countries, they are lacking in most LMICs, where the burden of HIV and cervical cancer is the highest. To prevent cervical cancer deaths among WWHs in LMICs, it is imperative …
