A Genomic Approach For Accurate Identification Of Closely Related Species With Next-Generation Sequencing Samples, Nour Al Dain Marzouka, Amira Al-Aamri, Fatima Alshamsi, Mariam Khalili, Sarah El Hajj Chehadeh, Meera S. Mohamed, Yassir Mohammed Eltahir, Rafeek Koliyan, Mohamed Moustafa Abdelhalim, Assem Attia, Mira Mousa, Guan Tay, Habiba Alsafar

Research outputs 2022 to 2026

Accurate species identification from Whole Genome Sequencing (WGS) data remains challenging, particularly for closely related species such as sheep (Ovis aries) and goats (Capra hircus). Through analysis of mapping quality metrics and Kraken2 taxonomic classification of 40 WGS sheep and goat samples, we demonstrate that conventional approaches yield ambiguous results, with overlapping alignment rates and inconclusive taxonomic assignments. We present a robust comparative genomic approach that uses species-specific genomic regions to distinguish these species in WGS samples. We define species-specific regions as those exhibiting distinctive coverage patterns: average coverage when samples are aligned to their matching reference genome but absent/low …

Natural Gas Hydrate Production And Co2 Storage Via Clathrate Hydrates: Challenges And Opportunities, Abdirahman Hassan Mohamed, Aliyu Adebayo Sulaimon, Haylay Tsegab, Bhajan Lal, Stefan Iglauer, Muhammad Ali

Research outputs 2022 to 2026

One of the most demanding environmental and economic challenges of this era is that of supplying the increasing global energy demand while reducing and neutralizing the CO2 footprint. In this regard, the provision of a secure and diversified energy supply and the sequestration of CO2 into geological formations are currently of great significance. However, the buoyant nature of CO2 under the temperature and pressure conditions of typical geological sites leads to the risk of CO2 leakage, and thus necessitates long-term monitoring. Therefore, the hydrate-based sequestration of CO2 beneath oceanic sediments has become a desirable alternative to conventional geologic sequestration in …

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 …

Thermally-Driven Equiaxation Of Columnar Grains And Α″ Nanoparticles Enabling Isotropic Β-Ti Alloys With Strength–Ductility Synergy Manufactured By Laser Powder Bed Fusion, Lei Qin, Shengfeng Zhou, Jianbo Jin, Huan Yang, Kunmao Li, Cheng Deng, Yujie Yuan, Lai-Chang Zhang

Research outputs 2022 to 2026

The transient thermal cycling characteristics during laser powder bed fusion (LPBF) induce elemental segregation and columnar growth, resulting in significant mechanical anisotropy and strength–ductility trade-off in titanium alloys. In order to break through this bottleneck, this work proposes a strategy of inducing equiaxation of columnar grains through recrystallization and regulating the morphology of the α″ phase (from an acicular shape to nanoparticles) to synergistically optimize the uniformity, strength and ductility of LPBF-fabricated Ti-35Nb-5Cu-xMo (Ti355x, x = 0, 1, 2, 4 wt%) alloys. The results demonstrate that LPBF-fabricated Ti355x alloys display equiaxed/columnar microstructures with significant mechanical anisotropy and strength–ductility trade-off. After …

In response, this paper presents the 3C Model (Context, Capabilities and Computational focus), a research-informed pedagogical framework designed to support pre-service and in-service teachers in delivering structured, curriculum-aligned instruction in coding and CT. Drawing on recent research, its findings, and its implementation in teacher education contexts, the 3C Model is presented as an innovative …

Dataset For Integrity Attacks On Time Synchronized Synchrophasor Data, Taylah Griffiths, Mohiuddin Ahmed, Chadni Islam

Research outputs 2022 to 2026

Phasor measurement units, also known as synchrophasors, are a vital component within smart grids to determine the stability of the grid. These devices send synchrophasor data to phasor data concentrators that collate and analyse the data. Recently, synchrophasor communication data has become beneficial for the research community. However, datasets covering cyberattacks on synchrophasor data are not public. Having access to this data would aid in investigating mitigations against cyberattacks. This paper describes a public specialized dataset, known as ECU-PMU-FDI/TSA. The dataset contains synchrophasor communication data for cybersecurity mitigation testing. Three hours of communication data was captured, from a simulated testbed. …

Efficient Charging Scheduling Through Coordination Of Electric Vehicle Platoons And Charging Stations, Liwan Qi, Bochun Wu, Shoubo Li, Yi Gong, Wei Ni

Research outputs 2022 to 2026

This paper focuses on charging allocation in a vehicle-to-infrastructure (V2I) communications-enabled electric vehicle (EV) network with heterogeneous traffic flows, where manned EVs and EV platoons coexist, and each EV platoon may have a different size and travel speed. In such a network, hybrid traffic flows pose significant challenges since platoons with multiple EVs can easily cause severe station overloading and increase the total time cost for charging service, particularly when large platoons occur. To tackle this issue, a centralized approach is proposed to plan charging allocation and optimize the velocities of manned EVs and EV platoons with the assistance of …

The Relationship Between Dietary Sodium Intake And Cognitive Function: A Narrative Review, Samantha L. Gardener, M. Fu, L. Morini, T. Schwartzkopff, G. Savage, R. N. Martins, S. R. Rainey-Smith

Research outputs 2022 to 2026

Purpose of Review: This narrative review provides discussion on current evidence regarding the relationship between sodium intake and cognitive function in animal and human studies, as well as potential mechanisms underlying this relationship. Recent Findings: Recent evidence suggests high sodium intake is associated with development of cognitive impairment and neural dysfunction. Additionally, studies have proposed that high sodium intake is associated with increased aggregation of Aβ-amyloid and that hypertension (for which high sodium intake is a risk factor) modulates the relationship between Aβ-amyloid and development of cognitive impairment and Alzheimer’s disease. However, while animal studies demonstrate a consistent relationship between …

Temptation At The School Fence: A Qualitative Exploration Of The Impact Of External Food Outlets On The School Community, Sharonna Mossenson, Klug, Jacinta Francis, Siobhan Hickling, Lukar Thornton, Gina Trapp

Research outputs 2022 to 2026

Retail food outlets are commonly located in close proximity to schools, providing students with opportunities to purchase and consume food enroute to or from school. These outlets are typically unhealthy and disproportionately clustered near schools, and this trend has been increasing over time. While quantitative studies have established associations between school food environments and adolescent dietary behaviours, little is known about how school personnel perceive and experience their impacts. This qualitative study explored perspectives of school personnel (n = 9) from a secondary school in Perth, Western Australia, located 150 m from two retail food precincts (areas with a high …

Research outputs 2022 to 2026

Background: Child stunting remains a persistent public health challenge in Peru. Although women’s empowerment has been linked to improved child health, evidence on its domain-specific relationship with stunting remains limited. The objective of this study was to assess the association between women’s empowerment, across attitudes towards violence, social independence, and decision-making, and child stunting in Peru.

Methods: We conducted an analytical cross-sectional study using nationally representative data from the 2021 Demographic and Family Health Survey (ENDES), including 16,650 mother-child pairs. Analyses of women’s empowerment were conducted in a sub-sample with complete SWPER data (n = 12,696). Stunting was defined as …

A Projector-Rank Partition Theorem For Exact Degrees Of Freedom In Experimental Design, K. G. Nagananda

Mathematics and Statistics Faculty Publications and Presentations

In many experimental designs—split-plots, blocked or nested layouts, fractional factorials, and studies with missing or unequal replication—standard ANOVA procedures no longer tell us exactly how many independent pieces of information each effect truly contributes. We provide a general degrees of freedom (df) partition theorem that resolves this ambiguity. For N observations, we show that the total information in the data (i.e., N −1 df) can be split exactly across experimental effects and randomization strata by projecting the data onto each stratum and counting the df each effect contributes there. This yields integer df—not approximations—for any mix of fixed and random …

Helixcross – Design And Development Of An Ai-Powered Cross-Examination Simulation For Forensic Expert Testimony Training, Mark Barash, Bruce Budowle

Faculty Research, Scholarly, and Creative Activity

Forensic testimony is where science meets the courtroom, and it is one of the critical forensic skills taught largely by apprenticeship. An examiner who overstates a match, mishandles a probability, or cannot support a method under direct or cross-examination can weaken the evidence in precisely the cases that rely on it. Yet in most forensic laboratories, testimony preparation remains largely informal, mentor-dependent, and unscalable. Consequently, many practitioners first face rigorous cross-examination at trial. To address this gap, HelixCross, an alpha-stage, publicly accessible, prompt-engineered large language model (LLM) agent, was developed. It uses retrieval-augmented generation (RAG) to simulate defense counsel cross-examination …

Recent Canadian Immigration Reforms And Their Consequences For Migrant Children And Families’ Health: The “Globalization Of Indifference”?, Rachel Kronick, Marianne Côté-Olijnyk, Efrat Arbel

All Faculty Publications

Despite its reputation as a welcoming nation to refugees, Canada has enforced increasing restrictions on asylum, even in the face of evidence from the United States and around the world of the profound harm such restrictions cause. In this paper, we outline recent Canadian legal and policy reforms and their potential impacts on refugee health equity. Following Farmer's approach of ethnographic case narratives that aim to portray how current policy and legislation are embodied and felt in migrants' lives, we document avoidable harms to migrant children and families. Our data come from qualitative research with inadmissible asylum seekers and narrative …

Correctional Officer Suicide: A Theory-Driven Investigation Of Acquired Capability And Suicide Behavior, Abigail R. Andersen

All-Inclusive List of Electronic Theses and Dissertations

A growing body of research suggests that correctional officers (COs) die by suicide at a significantly higher rate compared to the general population and some other public safety personnel. Despite what is known about this phenomenon, an understanding of the risk factors driving the high rate of suicide among this population remains unclear. Specifically, little attention has been paid to specific risk factors for suicide among this population and there is an overall absence of theory-driven research investigating CO suicide. The present study sought to address the gap in this area of research by investigating potential risk factors for suicide …

When The Bridge Is Not At Sea: Investigating Transfer Of Learning From Full Mission Bridge Simulator To Navigation Training Onboard, Thammawan Phanphichit

World Maritime University Ph.D. Dissertations

This dissertation explores, through a mixed-methods approach, how fullmission bridge simulators support transfer of learning to navigation training onboard, and under what conditions transfer can be trusted. Qualitative and quantitative components were integrated across the four articles. The first study explores how key onboard training stakeholders perceive its challenges, limitations, and the possibility of reducing required sea-time. Findings show broad agreement that OBT remains important, though openness to simulator use was conditional on credible evidence that simulator-developed competence can transfer onboard. The second and third studies examine this through transfer of learning theory. A systematic review identifies elements influencing transfer …
