Climate change is rapidly disrupting fish-related ecosystem services that underpin global food security, economic livelihoods, and cultural identity across both marine and freshwater systems. While impacts are increasingly recognised, disciplinary fragmentation has hindered integrated understanding of how climate-driven changes in fish populations affect ecosystem service delivery. This review makes two integrated contributions: a hierarchical synthesis tracing causal pathways from physical climate drivers through biological and ecological responses to socioeconomic outcomes, and a qualitative network analysis that maps the interconnections, implementation readiness, and strategic sequencing of seven major adaptation strategies. Ocean warming, acidification, deoxygenation, and their increasingly frequent co-occurrence as compound …

Creativity Development In Art Education: A Proposed Framework, Enock Swanzy-Impraim

Research outputs 2022 to 2026

Creativity and its development have been regarded as integral to 21st-century education. Although researchers have made several contributions to the development of creativity in schools, there remains a paucity of educational inventories on conceptual frameworks that tackle creativity development in its entirety, highlighting the essential constructs and elements required for the creativity-fostering process in the educational ecosystem. Therefore, this study proposes a framework that holistically provides a view of 11 elements necessary for successful facilitation of creativity in educational environments and the transition of creativity from policy to the local school system. These elements are: teachers’ training concerning creativity, teachers’ …

Examining Teachers’ Attitudes Towards Inclusive Education For All: Development Of A New Scale, Stephan Kielblock, Woodcock, John Ehrich

Research outputs 2022 to 2026

Teachers’ attitudes towards inclusive education are widely recognised as a key indicator of the inclusiveness of classroom environments. However, existing instruments inadequately capture teachers’ mindsets in relation to inclusive education for all learners. This study addresses this gap by developing and validating a new cross-cultural measurement instrument: the Attitudes Towards Inclusion for All scale (ATIFA), in both English (ATIFA-EN) and German (ATIFA-DE). Data were collected from pre-service and in-service teachers in Australia (n = 146) and Germany (n = 238). Exploratory factor analysis and Rasch modelling identified four robust subscales—Philosophy, Practice, Social Inclusion, and Support—with strong psychometric properties. Evidence of …

Robust Hybrid Tree-Based Machine Learning-Assisted Optimization Of Well Parameters To Reduce Asphaltene Precipitation Risk In Oil Fields, Malek Jalilian, Madani, Alireza Keshavarz, Stefan Iglauer, Abbas Khaksar Manshad, Amir H. Mohammadi

Research outputs 2022 to 2026

Asphaltene precipitation is a persistent flow-assurance issue in carbonate oil wells, leading to increased intervention frequency and production losses. This study utilizes multi-decade surveillance and operational data from a mature carbonate field (1983–2023) to train and optimize five tree-based models: Decision Tree, Random Forest, Extra Trees, Gradient-Boosting Decision Tree, and CatBoost, employing a Tree-Structured Parzen Estimator. These models, constrained by operational parameters, were integrated to identify optimal settings that can minimize the frequency of asphaltene precipitation and the subsequent cleanups. The novelty of this research lies in the direct integration of interpretable tree ensembles with an optimizer that adheres to …

Unpacking Environmental Racism Through Dependency Theory In The Case Of Second-Hand Goods Export To West Africa, Prince Nii Koi Kotei, Adusei-Asante, Shajimon Peter, Portia Nana Ama Brempong

Research outputs 2022 to 2026

The second-hand goods export market is complex and inextricably intertwined with environmental racism and dependency theories. Studies have shown that the adverse impacts of second-hand goods exports outweigh their benefits. West African countries are marginalised and are trapped in a dependency cycle. The literature discusses secondhand goods exports; however, it rarely situates this within the context of the dependency theory and environmental racism. This study seeks to address this gap by integrating several studies under a common theoretical framework connecting dependency theory to environmental racism. This study unpacks environmental racism through dependency theory in the export of second-hand goods. Specifically, …

Pretorius, Thomas R. Sullivan, Summer V.M. Walker, Johan Garssen, Jeffrey A. Keelan, Desiree Silva, Susan L. Prescott, Debra J. Palmer

Research outputs 2022 to 2026

Background: Prebiotic dietary supplementation has been shown to improve glucose homeostasis in type 2 diabetes patients. The aim of this analysis was to determine whether pre-pregnancy body mass index (BMI) modifies the effect of prebiotic supplementation from mid-pregnancy on reducing the risk of gestational diabetes mellitus (GDM). Methods: In a double-blinded, randomised controlled trial, pregnant women < 21 gestational weeks were randomly assigned (1:1) to consume daily prebiotics (14.2 g galacto-oligosaccharides and fructo-oligosaccharides) or placebo (8.7 g maltodextrin) powder. An effect modification analysis was performed to assess the heterogeneity of the effect of prebiotic supplementation in relation to pre-pregnancy BMI on GDM diagnosis. Results: Between June 2016 and November 2021, 329 women were assigned to the prebiotic group (50.4%), and 323 (49.5%) were assigned to the placebo group. Overall, 288 of 652 women (44.2%) were classified as overweight/obese prior to pregnancy (BMI ≥ 25 kg/m²). The distribution was balanced, with 146/329 (44.4%) randomised to the prebiotics group and 142/323 (44.0%) in the placebo group. Pre-pregnancy BMI modified the effect of prebiotic supplementation, with the intervention reducing GDM rates in women with a BMI ≥ 25 kg/m^{2 …}

Aluminium Based Hydrotalcite Like Compounds For Direct Lithium Extraction: A Critical Review On Crystallography And Structure Selectivity Design, Amin Sarmadi, Yasaman Boroumand, Mohammad Mahdi A. Shirazi, Magdalena Wajrak, Shayan Abrishami, Matthew Myers, Muhammad Rizwan Azhar, Amir Razmjou

Research outputs 2022 to 2026

The accelerating demand for lithium is intensifying interest in direct lithium extraction (DLE) technologies that minimise the environmental footprint of conventional solar evaporation ponds. Among sorbent-based DLE concepts, aluminium based hydrotalcite like compounds (Al-HTlc), particularly lithium aluminium layered double hydroxide (LiAl-LDH), are considered the most mature sorbent options, offering facile lithium (Li+) recovery and high selectivity in highly saline chloride based solutions. Both properties arise from a distinct intercalation mechanism wherein Li+ and its counter-anions (e.g. Cl− or SO42−) are co-intercalated into the crystal structure upon brine exposure. Li+ selectivity arises partly from a steric match between Li+ (ionic radius …
