Tippett, Julie Bernhardt, Kathryn S. Hayward

Research outputs 2022 to 2026

Background: Systematic reviews of randomised controlled trials with meta-analyses indicate that speech and language therapy for aphasia after stroke is effective in improving communication. However, high-quality evidence to identify an intervention’s target population (who), regimen (what), timing (when), and dose (how much) is lacking. The predominance of underpowered aphasia trials and comparative studies with design limitations may be attributed to: 1) the perceived complexity of designing trials of interventions for a complex behaviour such as human communication, 2) the lack of funded research in the field and 3) a lack of training and understanding in the field of aphasiology regarding …

Baseline Body Mass Index Category And Incident Treated Hypertension In Australian Men: A Linked Prospective Cohort Study Using Pbs/Mbs Data, Ebenezer Afrifa-Yamoah

Research outputs 2022 to 2026

Background: Excess adiposity is a major modifiable risk factor for hypertension; however, the incremental prognostic value of body mass index (BMI) beyond standard predictors remains unclear. We examined the associations between baseline BMI category and incident treated hypertension, and assessed whether BMI improved risk prediction.

Methods: Data were obtained from the Ten to Men longitudinal study (2013–2024) linked to Pharmaceutical Benefits Scheme (PBS) and Medicare Benefits Schedule (MBS) records. The cohort comprised 12,742 men aged ≥ 18 years without treated hypertension at baseline, followed for 133,038 person-years. Adjusted Cox proportional hazards models were fitted. Discrimination, calibration, decision curve analysis, E-values, …

Aim: To present a refined approach to analysing ethnographic data that preserves the distinctiveness of ethnography while ensuring it meets contemporary expectations of methodological rigour.

Design: Methodological discussion paper.

Data Sources: The approach draws on established ethnographic scholarship and is guided by Wolcott's framework for transforming qualitative data through three interrelated stages: description, analysis and interpretation. A practical application is illustrated through a focused ethnography exploring how older Vietnam-born Australians understand and manage chronic disease.

Implications for Nursing Practice: Focused ethnography has become increasingly popular in nursing research as it reflects the dual nature of the profession: striving to generate …

Beyond Compliance: Transformative Co-Design For Gender-Based Violence Prevention In Higher Education, Narelle Lemon, Christina Gray, Jason Goopy, Lisa Holmes, Bec Ball, Melissa Perry, Elisa Fear

Research outputs 2022 to 2026

This study examines how university staff and students experience transformative learning through voluntary participation in a gender-based violence (GBV) prevention programme that transcended compliance-oriented approaches. While universities increasingly rely on mandatory modules that fail to create sustainable change, this research investigates whether self-nominated participation and co-design pedagogy can foster genuine transformation and voice development among participants from diverse disciplinary backgrounds. A qualitative multi-method design examined eight university students (aged 18–24) at an Australian university through pre-post focus groups, observational field notes, and artefact analysis. Participants voluntarily engaged in workshops co-designing peer-focused social media prevention messaging. Inductive thematic analysis identified patterns …

Bishop’S Categories 40 Years On: Reclaiming And Sustaining Story And Culture Authors, Helen Adam, Libby Jackson-Barrett, Nicola Daly, Maria Nayr De Pinho Correia Ibrahim, Gloria Boutte

Research outputs 2022 to 2026

Bishop’s foundational framework for analysing multicultural children’s literature has provided essential tools for understanding cultural representation for almost 40 years. However, the evolution of First Nations children’s literature and the increased Indigenous control over publishing and storytelling suggest Bishop’s original three categories may not fully capture the complexity of contemporary Indigenous storytelling. This study reports on a comprehensive analysis of 750 books by and about Aboriginal and Torres Strait Islander peoples, employing yarning methodology and Indigenous research approaches to examine patterns of cultural representation across historical periods. Whilst Bishop’s categories remain relevant, two additional categories emerged: Culturally Sustaining and Cultural …

Combined Effect Of Porosity And Pore-Size Heterogeneity On Young’S Modulus Of Chemically Corroded Rocks, Hao Li, Zhenjiang You, Leo Pel, David Smeulders

Research outputs 2022 to 2026

Young’s modulus is a critical parameter for evaluating the stability of rock reservoirs, such as CO₂ geological storage. These reservoirs are exposed to chemically corrosions, which alter the pore structure, particularly porosity and pore size heterogeneity, thereby affecting Young’s modulus. This study conducted multiscale experiments to investigate how acid-driven chemical corrosion affects pore structure and its relationship with the Young’s modulus of rocks. Nuclear Magnetic Resonance (NMR) was used to characterize pore structure evolution, while corrosion mechanisms were examined via mass loss, XRD, pH monitoring, and ion chromatography. Based on the experimental results, a Kinetic Weibull Modulus (KWM) model was …

Commission Pathways For Sexual Offences Against Children: A Novel Methodological Approach Exposing Distinct Pathways As A Function Of Offending History, Kelly Jackson, Raphaële Arlettaz, Alfred Allan, Joseph Clare, Frank Morgan, Hilde Tubex

Research outputs 2022 to 2026

Purpose: Using neural network analysis, we examined how specific dispositional and situational factors influence pathways for the commission of sexual offending against children. Use of non-linear multifactorial models is still developing in psychological and criminological research, making this a unique contribution to these fields.

Method: We used prior offence status as the outcome variable in a multi-stage analytical strategy that included chi-squared analysis, sequential binary regression and neural network modelling. Subjects came from a database containing pre-collected psychological and criminological information on Western Australian men who had sexually offended. An initial sample of offenders convicted of sexual offences against children …

Community Attitudes Towards Voluntary Assisted Dying: Beyond Endorsed Eligibilities, Eyal Gringart, Craig Phillips, Deirdre Drake

Research outputs 2022 to 2026

Voluntary assisted dying (VAD) has been established across seven of Australia’s eight states and territories, yet empirical research on public attitudes remains limited. The current study examined Australians’ attitudes towards VAD. A cross-sectional online survey assessed affective, behavioural, and cognitive components, as well as overall attitudes, with 704 Australian adults. Attitudes were broadly supportive of VAD but conditional. Most participants endorsed end-of-life choices, legalisation of VAD, and access to VAD in cases of physical illness, and opposed availability for those with mental illness, and existential suffering. Participants with religious affiliations held significantly less favourable attitudes. Females and those with experience …

Crafting The Inspirational Teacher: Governing Through Affect As Policy Response To Teacher Recruitment In Australia, Saul Karnovsky, Brad Gobby, George Variyan, Andrew W. Wilkins, Antonio Olmedo

Research outputs 2022 to 2026

As policymakers address a teacher attrition crisis, this paper examines how the Australian policy response mobilises affect to address and manage teacher recruitment. Drawing on affect theory and governmentality, we analyse a case study–the Australian Government’s Be That Teacher campaign–as a policy instrument that seeks to cultivate among would-be-teachers desirable feelings and aspirations aligned with state priorities. Our analysis shows how a sentimental and idealised figure of the ‘inspirational’ teacher is mobilised as a form of affective governmentality through two interconnected dynamics: (1) the construction of teaching as emotionally fulfilling and morally meaningful work through narratives of inspiration, care, and …

Crisis, Credit Risk, And Productivity: Lessons From The Vietnamese Banking Sector During Covid-19, Van Nguyen, Phuong Thanh Le, Reza Kiani Mavi, Amir Arjomandi

Research outputs 2022 to 2026

This study investigates how an unprecedented systemic shock, the COVID-19 pandemic, reshaped bank productivity and intermediation efficiency in Vietnam, one of the fastest-growing emerging economies. We develop a novel risk-adjusted total factor productivity (TFP) measure based on the by-production Luenberger–Hicks–Moorsteen (LHM) indicator, which incorporates non-performing loans as undesirable outputs to better capture credit-risk dynamics. Using a balanced panel covering both the pre-pandemic and pandemic periods (2016–2022), our results show that Vietnamese banks experienced a general decline in productivity before and during COVID-19, driven largely by reductions in technical and scale efficiency. However, foreign and state-owned banks recorded stronger technological progress …

Decoupling Sustainability And Performance: How Government Infrastructure Projects In Australia Fare On Strategic Environmental Commitments, Richard Hughes, Kerry Brown

Research outputs 2022 to 2026

Australian government organisations are pivotal in helping to meet the United Nations sustainable development goals. Yet while these organisations promote sustainability in their strategic plans, they struggle to embed these same commitments into their own infrastructure and construction projects. This study examines this persistent disconnect using the lens of strategic decoupling, which explains how organisations symbolically align with external expectations while internal practices remain unchanged. Using a two-stage qualitative design, we conducted a positivist discourse analysis of strategic artefacts from six government organisations and a theoretically informed interpretivist analysis of 30 interviews with project professionals, framed by strong structuration theory. …

Development And Application Of A Frailty Index Derived From Patient-Reported Outcome Measures And Comorbidities In Oncology Patients, Divya Mathew, Heather Lane, David Ward, Rosemary Saunders, Lesley Millar, Christopher Etherton-Beer

Research outputs 2022 to 2026

Background: Emerging evidence supports the use of a frailty index as an objective measure of frailty. We constructed a frailty index from patient-derived outcome measures, as well as self-reported comorbidity data, and tested its correlation with survival.

Method: Data from 464 patients with lung, breast and colorectal cancer were obtained from the Continuous Improvement in Care – Cancer Project database, and a 42-variable frailty index was generated by dividing the total number of deficits present by the total number assessed and expressed as a ratio between 0 and 1. Frailty was defined as a frailty index of >0.2. Its association …

Inside Out: Improving Large Model Safety, Wei Zhao

Dissertations and Theses Collection (Open Access)

While Large Language Models (LLMs) and Multimodal Large Language Models (MLLMs) are at the frontier of current advancements in artificial intelligence, demonstrating remarkable capabilities across diverse applications, there are growing concerns about their reliability and security. LLMs remain vulnerable to adversarial attacks through carefully crafted prompts that circumvent safety mechanisms, while MLLMs face additional security challenges stemming from their multimodal nature. Despite considerable efforts in reinforcement learning from human feedback (RLHF) and supervised fine-tuning, existing safeguards have proven inadequate in addressing these critical vulnerabilities. This inadequacy stems from the fact that these models are inherently blackboxes that do not provide …

The Impact Of Corporate Mergers And Acquisitions On Performance From The Perspective Of Growth Pressure, Jiandong Wang

Dissertations and Theses Collection (Open Access)

Against the backdrop of economic volatility and intensified industry competition, firms generally face multidimensional growth pressures, including historical growth pressure, social growth pressure, and market competition pressure. Growth pressure is not only related to firms’ operational stability, but also profoundly influences their strategic choices, particularly merger and acquisition (M&A) behaviour.Grounded in performance feedback theory, this study constructs an integrated analytical framework encompassing growth pressure, M&A strategic decisions, and M&A performance, and systematically examines how different types of growth pressure affect firms’ M&A decisions, as well as how M&A performance varies across different firm characteristics and different types of M&A.

A Multi-Method Study Evaluating The Inference Of Compartmental Model Parameters From A Generative Agent-Based Model, Elizabeth Hunter, Jim Duggan

Research Outputs: 2025-Present

Calibrating process models such as compartmental SIR Models to real data can be performed using either optimization or Bayesian techniques. To accurately assess the performance of these methods, synthetic outbreak data can be used. All information about the data generative process is known for synthetic data, while when using real data there are many unknowns such as under-reporting of cases or real parameter values. We propose using an agent-based model to generate synthetic data. Calibrating to synthetic datasets created using different agent contact structures can provide us with information on how changes in contact structures impact SIR model parameters. We …

Mining companies need to modernize and automate to keep up with the ‘Fourth Industrial Revolution’, driven by disruptive technology, forcing systems and technologies to become more integrated, increasing cyber attack threats. To address this, we conducted a literature review analyzing the mining industry across various regions. The research is based on a qualitative analysis of diversified literature. The results highlighted factors behind the low uptake of …

Care-Full Climate Justice Organising, Kylie Wrigley

Research outputs 2022 to 2026

Feminist, Indigenous, and disability theories and activisms have long called for more attention to care–both as an ethic and practice–in response to environmental and social issues. Although care work is vital for collective survival, it is relatively devalued and trivialised in society and under-examined in climate justice research. Emerging critical research suggests that care work is central to how climate justice communities understand and respond to climate change and interlocking structural violences. Yet, there is limited climate justice scholarship that attends to the intersections of care and climate movements. At this juncture, this article draws on empirical reflections from a …

Managing Human Sources: Identification And Management Of Motivation, Tiffany Mckenzie, Pamela Henry, Nikki Rajakaruna

Research outputs 2022 to 2026

Human Source management is a critical function of intelligence and evidence collection by law enforcement and intelligence agencies across the world. Understanding the motivations of Human Sources is key to gaining high intelligence yields. Yet research which explores Human Source motivation, from a handler’s perspective, is limited. Even more limited is research which considers how motivation is identified and managed by law enforcement agencies across the course of a Human Source’s engagement with an agency. This research explores the experiences and perceptions of Human Source handlers from two Australian law enforcement agencies via semi-structured interviews (N = 17). Handlers highlighted …

Nation, Nature And Childhood In Five Curricula: Towards Earthly Education, Zsuzsa Millei, Katarzyna Gawlicz, Lucy Hopkins, Camilla Eline Andersen, Danielle Ekman Ladru

Research outputs 2022 to 2026

This article explores the relations between nation, nature and childhood in five early childhood education curricula in the Nordic, post-socialist and settler-colonial states with the focus on the role education plays in the face of the climate crisis. The authors identify three interconnecting themes in which nation, nature and childhood are entangled in these curricula: 1) national nature as an object of learning; 2) nature and home/birth land and Country; and 3) stewardship for national nature. Exploring these themes from the perspective of alternative pedagogies developed to address the child–nature relations during the Anthropocene, the authors argue that these notions …

Do Students Have Satisfying Educational Experiences At Sustainable Universities? Evidence From Australian Universities, Junru Zhang, Yuan George Shan, Nirosha Dilhani Kapu Arachchilage

Research outputs 2022 to 2026

Drawing on a sample of Australian universities from 2012 to 2018, we investigate the association between the extent of university sustainability disclosure and student satisfaction. University sustainability disclosures are critical for communicating with key stakeholders when seeking resources, thereby facilitating student satisfaction. Using hand-collected data from university annual reports and the Student Experience Survey, we find that the extent of university sustainability disclosure is positively associated with student satisfaction in both short and long terms. Our channel analysis suggests that sustainability disclosures help universities attract increased government funding and student income. Moreover, universities with a greater extent of sustainability disclosure …

Blending Minds, Balancing Goals: Tmt Heterogeneity And Sustainable-Innovation In Family Firms, Mahdi Vesal, Muhammad Aftab Alam, Mohammad H. Rahmati

Research outputs 2022 to 2026

Family firms often prioritize profitability and growth, but balancing these with environmental sustainability is challenging. While TMT heterogeneity shapes various performance outcomes, its role in addressing the profitability–environmental sustainability dilemma in family firms remains unclear. Building on the upper echelons theory, we investigate how TMT heterogeneity drives the simultaneous pursuit of financial and environmental performance, which we refer to as hybrid financial–environmental performance, through sustainable-innovation practices. Additionally, we examine how family-firm governance mechanisms influence these relationships. Analyzing data from two matched samples of CEOs and senior production managers of Australian family firms, we find not only that TMT heterogeneity enhances …
