Understanding The Role Of Home Community Environments In Shaping First-Generation Jamaican University Students’ Access And Persistence In Higher Education: Using Liming And Photovoice Methodologies, Shenhaye C. Ferguson

Electronic Theses and Dissertations

There are 15 national outcomes as part of Jamaica’s strategic goals for Vision 2030. Among the 15, the second outcome focuses on world-class education and training, the fifth looks at security and safety, and the fifteenth addresses sustainable urban and rural development (Vision 2030, 2018). First-generation Jamaican students represent a fraction of the Vision 2030 discussion around increasing access to higher education, eliminating crime and violence, poverty, and creating safe community environments. Accordingly, in (post)colonial Jamaica, challenges faced by first-generation students are compounded (Roofe et al., 2022). While many first-generation students attend universities in Jamaica, local studies examining first-generation students …

Cerebrospinal Fluid Levels Of Fatty Acid–Binding Protein 3 Are Associated With Likelihood Of Amyloidopathy In Cognitively Healthy Individuals, Kunal Dhiman, Victor L. Villemagne, Christopher Fowler, Pierrick Bourgeat, Qiao-Xin Li, Steven Collins, Christopher C. Rowe, Colin L. Masters, David Ames, Kaj Blennow, Henrik Zetterberg, Ralph N. Martins, Veer Gupta

Research outputs 2022 to 2026

Introduction: Fatty acid–binding protein 3 (FABP3) is a biomarker of neuronal membrane disruption, associated with lipid dyshomeostasis—a notable Alzheimer's disease (AD) pathophysiological change. We assessed the association of cerebrospinal fluid (CSF) FABP3 levels with brain amyloidosis and the likelihood/risk of developing amyloidopathy in cognitively healthy individuals. Methods: FABP3 levels were measured in CSF samples of cognitively healthy participants, > 60 years of age (n = 142), from the Australian Imaging, Biomarkers & Lifestyle Flagship Study of Ageing (AIBL). Results: FABP3 levels were positively associated with baseline brain amyloid beta (Aβ) load as measured by standardized uptake value ratio (SUVR, standardized β …

Introduction: We evaluated a new Simoa plasma assay for phosphorylated tau (P-tau) at aa217 enhanced by additional p-tau sites (p217+tau). Methods: Plasma p217+tau levels were compared to 18F-NAV4694 amyloid beta (Aβ) positron emission tomography (PET) and 18F-MK6240 tau PET in 174 cognitively impaired (CI) and 223 cognitively unimpaired (CU) participants. Results: Compared to Aβ− CU, the plasma levels of p217+tau increased 2-fold in Aβ+ CU and 3.5-fold in Aβ+ CI. In Aβ− the p217+tau levels did not differ significantly between CU and CI. P217+tau correlated with Aβ centiloids P =.67 (CI, P =.64; CU, P =.45) and tau SUVRMT P …

Exploring Scientists’ Perceptions Of Citizen Science For Public Engagement With Science, Stephanie A. Collins, Miriam Sullivan, Heather J. Bray

Research outputs 2022 to 2026

It is often assumed that citizen science is inherently participatory in nature. However, citizen science projects exist along a continuum from data contribution to full co-creation. We invited 19 biologists to explore their conceptions of citizen science. Almost all participants defined citizen science as involving non-scientists in data collection. This definition acted as a barrier for scientists who did not see how citizen science could suit their research objectives. While interviewees perceived many societal and experiential benefits of contributory citizen science, deliberate design is needed to realise the full potential of citizen science for public engagement

A Review On Security Issues And Solutions Of The Internet Of Drones, Wencheng Yang, Song Wang, Xuefei Yin, Xu Wang, Jiankun Hu

Research outputs 2022 to 2026

The Internet of Drones (IoD) has attracted increasing attention in recent years because of its portability and automation, and is being deployed in a wide range of fields (e.g., military, rescue and entertainment). Nevertheless, as a result of the inherently open nature of radio transmission paths in the IoD, data collected, generated or handled by drones is plagued by many security concerns. Since security and privacy are among the foremost challenges for the IoD, in this paper we conduct a comprehensive review on security issues and solutions for IoD security, discussing IoD-related security requirements and identifying the latest advancement in …

A Low-Cost Machine Learning Based Network Intrusion Detection System With Data Privacy Preservation, Jyoti Fakirah, Lauhim Mahfuz Zishan, Roshni Mooruth, Michael L. Johnstone, Wencheng Yang

Research outputs 2022 to 2026

Network intrusion is a well-studied area of cyber security. Current machine learning-based network intrusion detection systems (NIDSs) monitor network data and the patterns within those data but at the cost of presenting significant issues in terms of privacy violations which may threaten end-user privacy. Therefore, to mitigate risk and preserve a balance between security and privacy, it is imperative to protect user privacy with respect to intrusion data. Moreover, cost is a driver of a machine learning-based NIDS because such systems are increasingly being deployed on resource-limited edge devices. To solve these issues, in this paper we propose a NIDS …

Forty-eight participants, with 32 starting a community-based exercise program before the lockdown and 16 joining the program after the lockdown, completed a questionnaire survey about physical activities before and during the lockdown. This was followed by three focus groups (26 participants in total) to identify factors influencing physical activity behaviours found in the survey. The survey found that …

Testing The Limits Of International Society? Trust, Aukus And Indo-Pacific Security, Jamal Barnes, Samuel M. Makinda

Research outputs 2022 to 2026

When Australia reneged on a AUD$90 billion submarine contract with France in 2021 as it joined AUKUS, a new trilateral military partnership between Australia, the UK and the US, it was accused of lying and breaching France's trust. This perceived act of betrayal not only led to a deterioration in the diplomatic relationship between Australia and France, but it also drew attention to the consequences of violating the norm of pacta sunt servanda—agreements must be kept. Although it is recognized that breaches of trust undermine relationships, what has been underexplored is how a violation of norms can also undermine the …

Research outputs 2022 to 2026

Leptospirosis, typhoid and dengue are three water-related diseases influenced by environmental factors. We examined whether seasonality and rainfall predict reported syndromes associated with leptospirosis, typhoid and dengue in Fiji. Poisson generalised linear models were fitted with s6 early warning, alert and response system (EWARS) syndromic conditions from March 2016 until December 2020, incorporating seasonality, temperature and rainfall. Watery diarrhoea, prolonged fever and suspected dengue displayed seasonal trends with peaks corresponding with the rainy season, while bloody diarrhoea, acute fever with rash and acute jaundice syndrome did not. Seasonality was the most common predictor for watery and bloody diarrhoea, prolonged fever, …

Research outputs 2022 to 2026

Introduction/Purpose: The crossover point occurs during exercise when one transitions energy substrates from fat to carbohydrate predominance. The crossover point varies in an intensity-dependent manner; however, less is known about its specificity in sports with varying metabolic demands. The purpose of our study was to determine if various sports yield differences in the time to crossover and heart rate and percentage of maximal oxygen consumption (V O2max) at crossover during a standardized exercise protocol.

Methods: A total of 77 athletes (39 women, 38 men; 39.1 + 10.4 yr of age) were measured for respiratory exchange ratio during a modified Taylor …

A Framework Of Lightweight Deep Cross-Connected Convolution Kernel Mapping Support Vector Machines, Qi Wang, Zhaoying Liu, Ting Zhang, Shanshan Tu, Yujian Li, Muhammad Waqas

Research outputs 2022 to 2026

Deep kernel mapping support vector machines have achieved good results in numerous tasks by mapping features from a low-dimensional space to a high-dimensional space and then using support vector machines for classification. However, the depth kernel mapping support vector machine does not take into account the connection of different dimensional spaces and increases the model parameters. To further improve the recognition capability of deep kernel mapping support vector machines while reducing the number of model parameters, this paper proposes a framework of Lightweight Deep Convolutional Cross-Connected Kernel Mapping Support Vector Machines (LC-CKMSVM). The framework consists of a feature extraction module …

Patch Dynamics Driven By Wave Exposure In Subtidal Temperate Seaweeds Are Exacerbated By Warming Oceans, Yannick Mulders, Lydiane Mattio, Julia C. Phillips, Paul S. Lavery, Gary A. Kendrick, Thomas Wernberg

Research outputs 2022 to 2026

Over the past decades, ocean temperatures have been steadily increasing and are projected to continue to do so, stressing many temperate marine organisms. Changing temperatures do not affect ecosystems in isolation, but interact with many other factors in shaping ecological communities. We investigated the changes over 2 decades in subtidal temperate seaweed communities over a wave exposure gradient in Western Australia, a global warming hotspot. We found higher diversity in the seaweed community and a higher proportion of biomass of species with a warm affinity (expressed as the tropicalization index: TI) over time. There was no decline in biomass of …

Fundamental Data Analysis Tools And Concepts For Bioacoustical Research, Chandra Salgado Kent, Tiago A. Marques, Danielle Harris

Research outputs 2022 to 2026

Bioacoustics is a growing field of research in which sound is measured to gain knowledge about species’ natural history and their environments. For example, bioacousticians have been able to create phylogenies, identify populations, and estimate abundance using sound. Moreover, today, many animals are exposed to human-generated noise, which can impact animals’ behavior, ability to communicate, physiology, hearing, and, in some instances, survival. Bioacoustics, thus, is commonly used to assess and predict the impacts of anthropogenic noise on animals and their populations. The use of bioacoustics to address such research questions, however, is only effective provided the quantitative and statistical analysis …

Understanding Employee Travel Behaviours In Response To Workplace Relocation: A Case Study Comparing Commuting Patterns Between Subiaco And Perth, Western Australia, Emil E. Jonescu, Chamil E. Ramanayaka, Stephen Moorcroft, Dean Symington

Research outputs 2022 to 2026

Our built environments offer distinct variables that impact behaviour–throughout the world, and equally within Western Australia. However, an in-depth analysis of extant literature indicates that influencing human behaviour is difficult in the absence of a ‘disruption’ event. Accordingly, this organization-level study examined the disruptive effects of relocating from a Subiaco office to a new office in Perth’s Central Business District on the commute habits of its built-environment professional employees. The relocation occurred during a ‘non-lockdown’ period between July and August 2021 (southern hemisphere winter). The study sought to determine if an office relocation constituted a sufficient ‘disruption’ to affect employees’ …
