Research outputs 2022 to 2026

The purpose of this study was to develop, validate and confirm a scale to gain a better understanding of teachers’ beliefs in their capacity to use differentiated instruction in their classrooms. Differentiation is an effective approach to teaching, designed to enable equitable learning opportunities for every student. Teachers are recommended to differentiate aspects of teaching, instruction, learning, assessment and the learning environment due to the increasing student heterogeneity within classrooms worldwide. Emerging literature has suggested that teacher self-efficacy may influence how teachers use this teaching approach. It is unknown if there is an existing scale that measures teachers’ self-efficacy when …

Negotiating Relationships With Food, The Body, And Physical Activity: Who Is The Healthiest Of Them All?, Valeria Varea, Victoria Evans, Dawn Penney, Eibhlish O'Hara

Research outputs 2022 to 2026

Healthy eating and regular exercise are things that many people aspire to, mainly for health reasons. However, these practices can be complex given broader societal discourses. This paper aims to critically interrogate the social conditions and discursive formations that underpin everyday exercisers’ relationships with food, the body, and physical activity by using biopower and biopedagogies as a theoretical approach, and healthism as a set of discourses. Photo elicitation interviews with vignettes were conducted with nine participants who were regular exercisers. We constructed three different scenarios from the interview data and the theoretical approach: 1. Anna: A performance-driven, health compliant, private …

Research outputs 2022 to 2026

Epigenetic changes, in particular DNA methylation, accumulate with age across different tissues, but whether these changes follow consistent patterns across different organs remains poorly understood. Here we show, through a meta-analysis of more than 15,000 human methylation profiles spanning 17 tissues, that aging produces both conserved and tissue-specific epigenetic signatures. We identify systemic shifts in methylation levels, increases in methylation variability, and growing molecular disorder across tissues. Network analysis revealed tightly connected gene clusters that are not modified by beneficial interventions, alongside a more modifiable cluster linked to NAD⁺ metabolism, supporting NAD⁺ as a potential therapeutic target in …

Precarity On The Move: The Relative Economic Precarity Of Mobile Youth Moving To Australia, Lara Mckenzie, Anita Harris, Loretta Baldassar

Research outputs 2022 to 2026

Analyses of precarity often focus on how insecure employment, careers, finances, and geographies influence people’s lives for the worse, with young people understood as especially precarious in their economic stability and transitions to adulthood. This article analyses accounts of precarity amongst middling transnationally mobile youth, drawing from 24 semi-structured interviews incoming to Australia, and longitudinal survey data. We show that experiences of economic precarity are impacted by their access to work, government support, ability to access or sustain visas, and access to support from family and partners. By drawing on migration scholars’ observations that transnational mobility can be privileged and …

Precision Exercise For Breast Cancer-Related Outcomes: Towards Personalised Training Based On Tumour, Treatment And Patient Characteristics, Cristina Crespo-Garcia, Anita Borsati, Dennis R. Taaffe, Carolyn J. Peddle-Mcintyre, John P. Campbell, Alice Avancini, Emily Jeffery, Daniel A. Galvao, Robert U. Newton

Research outputs 2022 to 2026

Exercise is a promising strategy associated with improved cancer-related outcomes through multiple biological mechanisms. However, current exercise guidelines largely adopt a one-size-fits-all approach and overlook inter-individual variability in response. Given the heterogeneity of breast cancer, precision exercise prescriptions may better target biological pathways linked to therapeutic efficacy and long-term prognosis. Observational studies consistently show that higher physical activity levels are associated with improved survival outcomes, including reduced all-cause and breast cancer-specific mortality. In contrast, evidence from interventional trials remains limited and inconsistent, with effects on tumour response and survival largely derived from secondary or exploratory analyses. These discrepancies likely reflect …

Tall Orders: A Comparison Of Resident Food Behaviours By Dwelling Type And Apartment Characteristics In Australia, Joelie Mandzufas, Siobhan Hickling, Kevin Murray, Sarah Foster, Gina S.A. Trapp

Research outputs 2022 to 2026

To accommodate population growth, Australian cities are becoming denser, with more Australians living in apartments. However, there is little understanding of whether this shift towards apartment living raises any potential short- and long-term implications for dietary health. Using an Australian nationally representative household survey, this cross-sectional study compared meal-purchasing frequency and fruit and vegetable intake by dwelling type, apartment block height, and number of bedrooms in the apartment. Adjusted mean differences were derived from linear regressions, adjusting for socio-demographic characteristics. Apartment residents purchased 0.72 more meals out each week than house residents (p < 0.001, 95% CI [0.599,0.831]) and consumed 0.10 fewer daily serves of vegetables (p = 0.002, 95% CI [0.038,0.163]). Among apartment residents, those in high-rise blocks purchased 0.80 more meals out each week than low-rise residents (p = 0.012, 95% CI [0.250,1.348]), and residents of one-bedroom or studio apartments ate 0.25 fewer serves of fruit per day than residents in apartments with at least three bedrooms (p = 0.003, 95% CI [0.038,0.163]). These findings provide important evidence to inform policy and targeted interventions that promote healthy food behaviours in apartment-living populations.

Nettleton, Hwi Eun Mary Shim, Joanne Abbotsford, Zoy Goff, Briony Hazelton, Matthew O'Brien, Tenielle Porter, Thomas Snelling, Daniel K. Yeoh, Asha C. Bowen, Christopher C. Blyth, Anita J. Campbell

Research outputs 2022 to 2026

Background: Vancomycin is first-line treatment for methicillin-resistant Staphylococcus aureus (MRSA) infections. However, despite guideline recommendations, there is no evidence that targeting vancomycin trough concentrations of ≥15 mg/L in children confers clinical benefit and is associated with vancomycin-associated nephrotoxicity (VAN). Aim: This study aimed to evaluate the impact of a vancomycin safety bundle on VAN and vancomycin utilisation in hospitalised paediatric inpatients. Method: A pre–post-intervention study was conducted in a tertiary paediatric hospital comparing January–December 2018 (pre-intervention) to May 2019–April 2020 (post-intervention). Hospitalised children, aged 30 days to <18 years, that received intravenous vancomycin with at least one trough concentration were included. The intervention bundle comprised: (1) lowered empiric vancomycin trough targets (5–15 mg/L), (2) enhanced creatinine monitoring (concomitant serum creatinine with vancomycin trough), (3) guideline modification (reduced pre-authorised indications for empiric vancomycin use), and (4) prescriber education initiatives. Ethical approval was granted by the WA Child and Adolescent Health Service Research Ethics Committee, Governance Evidence Knowledge Outcomes Program (Reference no: 41830) and the study conforms with the National Health and Medical Research Council's Ethical considerations in quality assistance and evaluation activities. Results: A total of 314 vancomycin prescriptions were analysed (n = 204 pre-intervention; n = 110 post-intervention). Post-intervention, VAN incidence decreased almost twofold from 0.46 to 0.25 episodes per 1000 patient bed days (p ≤ 0.01), and vancomycin prescription days decreased by 19%. Total hospital drug costs for vancomycin decreased by AUD $16 033. Overall, and for paediatric invasive MRSA, no significant difference in clinical outcomes or 30-day mortality was observed between study periods. Conclusion: This study demonstrated the implementation of a vancomycin safety bundle significantly reduced paediatric VAN and vancomycin utilisation without compromising clinical outcomes. These data support antimicrobial stewardship interventions to improve medication safety for children.

Utilizing a quantitative approach and guided by equity and social justice theories, the study employs partial least squares …

Thinking With Trees: Responding To Sympoietic Plant Relations Through Visual Art, Xiaoyu Yang

Research outputs 2022 to 2026

Societal Impact Statement: Amid escalating climate crises, this paper explores how we might rethink our relationship with the natural world, particularly with plants and trees, through the perspectives of visual art. This paper reveals how art invites us to see trees and other plant life not as passive background scenery, but as living beings with their own forms of experience and individuality. Rather than offering technical solutions to the climate crisis, visual art creates something equally important: a shift in how we think and feel about ‘othering’ non-human life. By making visible the inner lives and behaviours of plants, art …

Understanding Amenities In Peer-To-Peer Accommodation Platform: A Moderation Analysis, Emeka Ndaguba, Kerry Brown, Neda Kiani Mavi

Research outputs 2022 to 2026

This study examines how amenities shape revenue performance in short-term rental (STR) markets by moving beyond additive feature models towards a configurational perspective. Using robust linear modelling on 14,630 Airbnb listings in regional Western Australia (2022–2024), the analysis tests both individual amenity effects and amenity complementarities. Results show that autonomy-enabling and niche-signalling amenities, such as kitchens and pet-friendliness, are positively associated with revenue, while some amenities, notably pools, reduce revenue when offered in isolation. Interestingly, interaction effects reveal that specific amenity bundles–particularly pool × pet-friendliness and kitchen × parking–generate synergistic value that exceeds the sum of individual effects. These findings …

Enfranchising Fluoride: A Case For Democratic Decision-Making In What We Drink, Samuel N. Dick, R. Chase Bailey

Wyoming Law Review

For years, the addition of fluoride in drinking water has been hailed as a powerful agent for dental health. But the closer you look, the more cracks appear—making the truth that much harder to swallow.

This Article is the first to look objectively at the benefits and risks of water fluoridation following Food & Water Watch, Inc. v. EPA. Notably, the court there held that fluoride poses an unreasonable risk to human health, marking a striking departure from those who, as recently as 2024, have continued to herald water fluoridation as one of the greatest public health interventions of …

Two Strategies To Improve Stability In A Precision-Based Task: Insights From The Badminton Short Serve, Yochi Iino, Jodie Cochrane Wilkie, Senshi Fukashiro, Shinsuke Yoshioka, Shayne Vial

Research outputs 2022 to 2026

The badminton short serve is a highly precise task requiring accurate control of racquet face orientation, which directly influences shuttlecock trajectory and limits an opponent's ability to attack. Previous studies on motor redundancy have emphasized covariation among elemental variables as the primary mechanism for stabilizing performance. However, when the sensitivities of elemental variables differ, performance can also be stabilized by unevenly distributing individual variances without altering correlation — an approach that has received limited attention. This study investigated whether elite players use both the correlation strategy and the uneven variance strategy to stabilize racquet face angles during the short serve. …
