Electromagnetically Forced Flows in Shallow Electrolyte Layers
No full textElectromagnetically forced flows in shallow electrolyte layers offer a versatile and nonintrusive method for exploring quasi-two-dimensional fluid dynamics. This review focuses on the experimental and theoretical aspects of such flows driven by Lorentz forces generated by the interaction of injected electric currents and the applied magnetic fields. The method is applicable to both liquid metals and electrolytes, with the latter more commonly used due to their wide availability and ease of handling. Experimental aspects of the method and key components of mathematical flow analysis are discussed. Initially developed for geophysical flow modeling, the method has been instrumental in exploring various other physical phenomena including vortex and wake dynamics, spatiotemporal chaos, and mixing processes. The review also addresses the challenges of achieving true two-dimensionality in laboratory settings and discusses the influence of various parameters, such as layer thickness and forcing intensity, on the flow behavior. Future research directions in the field are highlighted.</p
Human Thinking-Inspired Models for Financial Market Trading
No full textThis research develops new models inspired by how the human brain processes information to improve the prediction of financial markets. By reducing the need for complex computations, these models can analyse data more quickly and adapt to fast-changing market conditions. The study shows how brain-inspired approaches can make financial forecasting more efficient, robust, and accessible. The outcomes contribute to building intelligent systems that support better decision making in trading and investment.</p
Investigation into the Interface of Organic and Inorganic Materials for the Optimisation of Electrochemical Reactions
No full textRising atmospheric CO2 levels, the highest in 800,000 years, demand alternatives to fossil fuels. Hydrogen offers a clean, CO2-free energy source when produced from renewable electricity and water, but efficient catalysts are essential. This thesis investigates how organic and inorganic materials interact with electrode surfaces to enhance catalytic performance. The studies show that the interface between organic and inorganic materials can tune the electrooxidation process, enabling the conversion of low-value commodity chemicals into higher-value products.</p
Food Waste Ninjas and Sleeping Sheep: Understanding how collaboratively designing vernacular data visualisations in self-trackers influence consumer food-wasting habitual behaviours
No full textThis research investigates how collaboratively created, analogue data visualisations can support long-term reductions in household food waste. In contrast to conventional digital tracking tools which raise concerns around ethics, efficacy, and exclusion, this study explores playful, physical representations of data co-designed with participants. Conducted over nine weeks across 30 Australian households, the study found that engaging participants in the creation of their own visual data fostered sustained behavioural change. The findings suggest that vernacular approaches to data visualisation can enhance agency, reflection, and accountability, offering a more inclusive and context-sensitive model for designing environmental behaviour change interventions.</p
Making financial abuse visible: Embedding women's and children's voices in policymaking and research
No full textBy bringing together perspectives spanning advocacy, service organisations, and researchers working in the field of financial abuse prevention and intervention, this white paper shows the gaps in current data collection tools, such as the personal safety survey (ABS, 2024). The paper also discusses who needs to have a seat at the table in future data collection and research design.</p
Theorizing Lean as a Socio-Technical System: Examining the Reciprocal Interactions between Lean Social and Technical Subsystems
No full textLean enhances efficiency and supports continuous improvement. However, the dynamic interaction between its social (soft) and technical (hard) subsystems remains insufficiently explored. Existing research has largely examined these subsystems in isolation which this study addresses by examining their interaction as a balanced socio-technical system (STS) at multiple performance levels. Adopting a socio-technical systems theoretical lens, we used the ‘antecedents-phenomenon-consequences’ process logic to operationalize the interplay between the social and technical subsystems of Lean by conducting a critical and systematic review of 58 peer-reviewed empirical studies. This analysis led to the development of three process theory models, from which three propositions have been derived, highlighting the reciprocal interactions between these subsystems. First, paradoxical and dialectical tensions are inherent in the Lean technical subsystem, limiting its contributions at the individual, group, and organizational levels. Second, the Lean social subsystem, which comprises employee empowerment, training, work design, cross-functional collaboration, and management involvement, addresses these tensions. Third, Lean, as a symbiotic socio-technical system, fosters synergies that enhance operational performance, bolster dynamic capabilities, and drive process innovation. For practitioners, this study offers actionable insights into balancing the social and technical aspects of Lean to effectively manage tensions and achieve performance gains.</p

The Financial Wellbeing Program is delivered to jobs-focused social enterprises in Australia, with the aim of supporting them to provide tailored training to enhance social enterprise employees’ financial knowledge, confidence and skills.</p
The Distinctiveness and Stability of Employee Attitudes Toward Change and Their Relationship with Leadership: A Longitudinal Study
No full textWe examined state-readiness for change and trait-resistance to change, and assessed the distinctiveness of the two constructs, their stability over a four-to-six-month period, and the capacity for each to be influenced by transformational leadership. Equivalence testing suggested that each construct was measuring a distinct phenomenon. However, neither readiness for a specific change (state-readiness) nor resistance to organizational change in general (trait-resistance) were particularly stable over time (rs = .31, .30). In addition, while transformational leadership was significantly correlated with both state-readiness and trait-resistance at Time 1 (rs = .40, –.24), it was only significantly correlated with state-readiness at Time 2 (r = .34). Transformational leadership at Time 1 had a small predictive relationship with state-readiness several months later at Time 2 (r = .20). However, this predictive relationship was no longer significant after controlling for precursory and contemporaneous employee attitudes toward change. Results are discussed with a particular focus on the management of unplanned change events such as the recent Covid-19 pandemic. The implications of this research for traditional versus emerging leadership ontologies are also explored.MAD statementIn the aftermath of the COVID-19 pandemic, where workplaces were required to implement major changes with little advance notice, the stability of employee attitudes toward change has been a critical consideration. The present study suggests that organizations may approach their preparations for future unplanned changes with a degree of optimism. Employee attitudes toward change may be less stable than previously suggested. Our findings revealed that the behaviour of designated leaders had only a small and temporary association with employee attitudes toward change. The study suggests the promise of emerging leadership perspectives that reconceptualize leadership as a collective social process driven by all employees during times of significant change.</p
Lipid Abnormalities among Myocardial Infarction Patients and Evidence-based Approach to Improve Lipid Parameters
No full textLow-density lipoprotein cholesterol(LDL-C) is a prognostic biomarker for heart attack, whereas lipoprotein (a)[Lp(a)] and PCSK9 are lipid parameters likely to contribute to residual cardiovascular risk. Our study demonstrated that heart attack patients had improvement in their fasting lipid profile with high-intensity statins(atorvastatin 40mg), but only 33.1% achieved target LDL-C<1.8mmol/L at 3-months post-discharge, with no difference in Lp(a) and PCSK9. Total cholesterol, triglyceride and atorvastatin concentration improved significantly in integrated approach group (increasing atorvastatin dose and medication adherence counseling) at 7-months compared to standard of care approach. Self-reported medication adherence with measuring atorvastatin concentration can reflect real life medication adherence.</p
