Background: Flavonoids may play a role in mitigating atherosclerotic cardiovascular diseases, with evidence suggesting effects may differ between vascular beds. Studies examining associations with subclinical markers of atherosclerosis between subpopulations with different underlying risks of atherosclerosis are lacking. METHODS: Among 5599 participants from the MESA (Multi-Ethnic Study of Atherosclerosis), associations between dietary flavonoid intakes (estimated from a food frequency questionnaire) and subclinical measures of atherosclerosis (ankle-brachial index, carotid plaques and intima-media thickness, and coronary artery calcification) were examined using repeated measures models. Exposures and outcomes were measured at exam 1 (2000-2002) and exam 5 (2010-2011). Stratified analyses and interaction terms …

Levels Of Unrelated Diversification And Firm Performance: A Conceptual Description Of An S-Shaped Hypothesis, Kwaku Alex Gyan

Research outputs 2022 to 2026

This study reconceptualizes the so far inconclusive relationship between unrelated diversification and financial performance by explaining how coordination costs can shape the amount of free cash flow and related agency problems at different levels of unrelated diversification. The study builds upon the notion that coordination requirements and associated coordination costs will vary at levels of unrelated diversification to regulate the amount of free cash flow managers will have at their disposal at each level of unrelated diversification. Based on the agency costs associated with free cash flow, we conceptualize that at different stages of unrelated diversification, the degree of managerial …

White Lies And Safety Nets: The Perceptions Of Nurses On The Use Of Early Warning Systems And The Development Of Higher-Order Thinking Skills, Deb Massey, Tracy Flenady, Amy Louise Byrne, Justine Connor, Danielle Le Lagadec

Research outputs 2022 to 2026

Background: Algorithmic tools such as early warning systems (EWSs) have been embedded into clinical practice globally to facilitate the early recognition of patient deterioration and to guide the escalation of care. Concerns have been raised that the mandated use of these EWS tools may impact the development of nurses' higher-order thinking. However, the relationship between EWS tools and the development of higher-order thinking is poorly understood.

Objectives: This paper provides the qualitative results of a larger study that sought to explore the impact of EWS tools on the development of nurses' higher-order thinking. The objective of this component of the …

Authentic Leadership: 20-Year Review Editorial, Andrei A. Lux, Kevin B. Lowe

Research outputs 2022 to 2026

Our field has reached a critical juncture. Authentic leadership, which once promised to illuminate how leaders inspire and influence through genuine actions, has become mired in conceptual ambiguity and ideological bias. Much of the research is based on evaluations of behaviour conflated with antecedents and outcomes, presuming an oversimplified, positive view of authenticity. To advance, we must refocus on what authentic leaders actually do – their discrete behaviours – as signals of leadership. In this editorial, we redefine authentic leadership through signalling theory to address unresolved critiques and provide a platform for meaningful progress. We then summarise and synthesise the …

This pilot mixed methods study explores the impact of Human-Empathy Accessibility Learning (HEAL) interventions on soft skills development in undergraduate computing students, emphasizing their role in job readiness and perceived employability. HEAL interventions aimed to enhance accessibility awareness, focusing on motivation, empathy, and emotional intelligence. Participants were assigned to control and experiment groups, with qualitative findings showing empathetic growth in the experiment group. Quantitative results partially supported qualitative findings, indicating statistically significant changes across measures. Despite quantitative limitations, short-term empathy interventions showed potential benefits for job readiness. The study discusses implications of mixed findings and recommends future research directions.

Optimizing Resistance Training For Sprint And Endurance Athletes: Balancing Positive And Negative Adaptations, Bas Van Hooren, Per Aagaard, Anthony J. Blazevich

Research outputs 2022 to 2026

Resistance training (RT) triggers diverse morphological and physiological adaptations that are broadly considered beneficial for performance enhancement as well as injury risk reduction. Some athletes and coaches therefore engage in, or prescribe, substantial amounts of RT under the assumption that continued increments in maximal strength capacity and/or muscle mass will lead to improved sports performance. In contrast, others employ minimal or no RT under the assumption that RT may impair endurance or sprint performances. However, the morphological and physiological adaptations by which RT might impair physical performance, the likelihood of these being evoked, and the training program specifications that might …

Queering Apocalyptic Methodologies: Enacting The Utopian Performative Through Extended Reality Artwork, Cassandra Tytler

Research outputs 2022 to 2026

This paper takes its cue from Koro and Wolgemuth's conceptual writing on Apocalyptic Methodologies as an extended prompt to enact the utopian performative as a form of generative Queer Ecopedagogy. A utopian performative is the performance of future potential that critiques our present political moment, highlighting that the present is not enough. The paper offers a troubling of "nature"and place, in its suggestion that digital space can be a refuge for EE practice. It looks to virtual reality as a realm used to create space free from the constraints of colonial history or normative prescriptions of the non/human binary. The …

Gordon, Manonita Ghosh, Chandana Guha, Sarah Hilmer, Lisa Kouladjian O’Donnell, Benignus Logan, Kristiana Ludlow, Michelle Miller, Mark Morgan, Alison Mudge, John Muscedere, Donna Reidlinger, Kenneth Rockwood, Rosemary Saunders, David Ward, Paul Yates

Research outputs 2022 to 2026

Frailty is an important concept in the care of older adults. Over the past two decades, significant advances have been made in measuring frailty. While it is now well-recognised that frailty status is an important determinant of outcomes from medical illnesses or surgical interventions, frailty measurement is not currently routinely integrated into clinical practice. In the community setting, it is uncommon for general practitioners to deliver frailty-optimised care. In hospitals, there is substantial variability in how people living with frailty are managed. This variability is notable between and even within disciplines. Furthermore, gains from understanding frailty mechanisms and risk factors …

Dismantling Pervasive Gender Stereotypes In Healthcare Leadership Contexts With An Ecological Systems Theory Approach, Andrei A. Lux, Nasim Salehi, Diarmuid Hurley, Elizabeth Emanuel

Research outputs 2022 to 2026

Leadership emergence is fraught with pervasive gender stereotypes, and women remain underrepresented in senior leadership roles, particularly in healthcare organisations. We apply ecological systems theory to explain how environmental factors enable or inhibit women’s leadership emergence in healthcare settings. We interviewed 17 senior female leaders in the Australian healthcare sector to explore how gender-related perceptions affected their leadership journeys. Five themes emerged that challenge existing narratives: men supported women’s advancement; women impeded other women’s progress; vulnerability was a leadership strength; ambitious women were ostracised; and women were ‘given’ leadership opportunities rather than actively pursuing them. By situating these findings within …

Developing An 'Eportfolio Of Evidence' Towards Employment And Registration For Early Childhood Teachers, Pauline Roberts, Leonie Menzel, Bev Adkin, Lennie Barblett

Effective Land Use Classification Through Hybrid Transformer Using Remote Sensing Imagery, Muhammad Zia Ur Rehman, Syed Mohammed Shamsul Islam, Anwaar Ulhaq, David Blake, Naeem Janjua

Research outputs 2022 to 2026

Recent advances in deep learning for hyperspectral image (HSI) classification have shown exceptional performance in resource management and environmental planning through land use classification. Despite these successes, challenges continue to persist in land use classification due to the complex topology of natural and man-made structures. The uneven distribution of land cover introduces spectral-spatial variability, causing inter- and intra-class similarity. To address this issue, this study adopts a hybrid approach that combines convolutional neural networks (CNNs) and a transformer model. The technique comprises three key components: a spectral-spatial convolutional module (SSCM), a spatial attention module (SAM), and a transformer module. Each …

Economic Material For Large-Scale H2 Storage And H2-Co2 Separation, Hussein R. Abid, Alireza Keshavarz, Header Jaffer, Basim K. Nile, Stefan Iglauer

Research outputs 2022 to 2026

Hydrogen is a clean fuel that can potentially completely decarbonize the energy supply chain and mitigate global warming. Hydrogen – a highly volatile gas – however, needs to be separated from CO2 during H2 production, and also from cushion gas in H2 geo-storage projects; in addition, large-scale H2 storage is a key obstacle. We thus tested and chemically upgraded common sub-bituminous coal as a material for H2-CO2 separation and H2 storage. The coal adsorbed significant amounts of H2 and CO2 and demonstrated an excellent H2-CO2 separation efficiency if chemically modified. The work presented here thus provides fundamental data required for …

Predicting Neurodegeneration From Sleep Related Biofluid Changes, Yue Yang, Woojin S. Kim, Johannes C. Michaelian, Simon J. G. Lewis, Craig L. Phillips, Angela L. D'Rozario, Pratishtha Chatterjee, Ralph N. Martins, Ron Grunstein, Glenda M. Halliday, Sharon L. Naismith

Research outputs 2022 to 2026

Sleep-wake disturbances are common in neurodegenerative diseases and may occur years before the clinical diagnosis, potentially either representing an early stage of the disease itself or acting as a pathophysiological driver. Therefore, discovering biomarkers that identify individuals with sleep-wake disturbances who are at risk of developing neurodegenerative diseases will allow early diagnosis and intervention. Given the association between sleep and neurodegeneration, the most frequently analyzed fluid biomarkers in people with sleep-wake disturbances to date include those directly associated with neurodegeneration itself, such as neurofilament light chain, phosphorylated tau, amyloid-beta and alpha-synuclein. Abnormalities in these biomarkers in patients with sleep-wake disturbances …
