Research outputs 2022 to 2026

Audio-image representations for a multimodal human action (MHAiR) dataset contains six different image representations of the audio signals that capture the temporal dynamics of the actions in a very compact and informative way. The dataset was extracted from the audio recordings which were captured from an existing video dataset, i.e., UCF101. Each data sample captured a duration of approximately 10 s long, and the overall dataset was split into 4893 training samples and 1944 testing samples. The resulting feature sequences were then converted into images, which can be used for human action recognition and other related tasks. These images can …

Multimodal Fusion For Audio-Image And Video Action Recognition, Muhammad B. Shaikh, Douglas Chai, Syed M. S. Islam, Naveed Akhtar

Research outputs 2022 to 2026

Multimodal Human Action Recognition (MHAR) is an important research topic in computer vision and event recognition fields. In this work, we address the problem of MHAR by developing a novel audio-image and video fusion-based deep learning framework that we call Multimodal Audio-Image and Video Action Recognizer (MAiVAR). We extract temporal information using image representations of audio signals and spatial information from video modality with the help of Convolutional Neutral Networks (CNN)-based feature extractors and fuse these features to recognize respective action classes. We apply a high-level weights assignment algorithm for improving audio-visual interaction and convergence. This proposed fusion-based framework utilizes …

There are three strands to this project: an overview of Biberian’s life, philosophy, and music; a musical apprenticeship with Biberian on technique and musicianship; and also on my compositions. There will be …

Expression Of Growth Differentiation Factor 15 (Gdf-15) In Placental Tissue Of Full- Term Pregnant Women With Hypertensive Disorders In A Western Australian Population, Elsa H. L. Chew

Theses: Doctorates and Masters

Women who experience hypertensive pregnancy disorders (HPDs) during pregnancy, mainly pre-eclampsia (PE), are four times more likely to develop hypertension after pregnancy and therefore have an increased risk of developing cardiovascular diseases (CVD) in the future. Pregnancy involves a high level of cardiovascular stress and the development of some complications. This has the potential to increase a woman’s susceptibility to vascular or metabolic disease risk in the future. In this research, pre-eclampsia (PE) and pregnancyinduced hypertension (PIH) were representatives of HPDs and were analysed together for the expression of Growth Differentiation Factor-15 (GDF-15) relative to their healthy agematched controls.

GDF-15 …

The Food And Habitat Effects Of Detrital Kelp As A Trophic Subsidy To Seagrass-Inhabiting Mesograzers, Jessica Billinghurst

Theses: Doctorates and Masters

Seascapes are connected through the transfer of energy from the movement of fauna, detritus, and nutrients among habitats. This exchange of resources can influence food web dynamics in the recipient system, increasing productivity and biodiversity, thus creating spatial subsidies. Spatial subsidies are usually characterised by the transfer of resources from highly productive donor systems to lower productive recipient systems. However, recent work suggests that recipient systems with comparably high productivity, such as seagrass meadows, may benefit from spatial subsidies. Kelp is regularly eroded from reefs and provides a vector for nutrient and detrital transfer to seagrass meadows, where it can …

Novel Methods For Assessing Pulmonary And Cardio-Vascular Limitations To Aerobic Performance In Older And Younger Populations, Toni Haddad

Theses: Doctorates and Masters

Around the world, life expectancy is increasing, the ageing population is growing, and maintaining quality of life at an older age currently represents a major global challenge. While ‘successful ageing’ relies on a variety of factors, aerobic performance and exercise capacity are key determinants and attenuating their decline is of the utmost importance. The decrease in maximal oxygen consumption is often considered as a major determinant explaining the age[1]related decline in aerobic performance. Yet, multiple physiological systems are impaired with ageing and their contribution to aerobic limitation in older individuals is unclear. Understanding how the limitations to aerobic performance may …

Thulborn, Mahdi Mahdi, Christine A'Court, Ian Binnian, Stephen Bright, Simon Cartwright, Victoria Glover, Alison Law, Robin Fox, Adam Jones, Christopher Davies, David Copping, Richard E. K. Russell, Mona Bafadhel

Research outputs 2022 to 2026

Background: Systemic glucocorticoids are recommended for use in chronic obstructive pulmonary disease (COPD) exacerbations; however, there is increased harm associated with their use. We hypothesised that the use of eosinophil biomarker-directed oral prednisolone therapy at the time of an exacerbation of COPD was effective at reducing prednisolone use without affecting adverse outcomes. Methods: The studying acute exacerbations and response (STARR2) study was a multicentre, randomised, double-blind, placebo-controlled trial conducted in 14 primary care practices in the UK. We included adults (aged ≥ 40 years), who were current or former smokers (with at least a 10 pack year smoking history) with …

The Commonwealth Of Amnesia: A Collection Of Erasure And Cut-Up Poems Exploring The Forgotten Histories Of Croatian And Yugoslav Peoples In Australia And An Exegesis Obliteration Creates More: Examining The Wreck Of History Through Whiteout, Blackout And Cut-Up Erasure Poetry, Natalie Damjanovich-Napoleon

Theses: Doctorates and Masters

This thesis consists of two parts, a collection of poems, “The Commonwealth of Amnesia”, and an accompanying exegesis. The collection explores the forgotten histories of Croatian and Yugoslav immigrants in Australia from 1901 to 1957 through the medium of erasure and cut-up poetry, re-arranging words found in nonfiction documents to posit that forgetting can be metaphorically and visually represented through erasure while also re-narrativising a text. Erasure poetry takes a textual document and using whiteout or blackout erases portions of a text, transforming that text into a poem; cut-up poetry rearranges the words of a document in a textual version …

Customer Experience Quality With Social Robots: Does Trust Matter?, Sanjit K. Roy, Gaganpreet Singh, Saalem Sadeque, Richard L. Gruner

Research outputs 2022 to 2026

Although service providers increasingly adopt social robots, much remains to be learned about what influences customers' experiences with robots. To address this issue, this study investigates the relationships among customer equity drivers (i.e., value equity, brand equity and relationship equity), trust in social robots, and trust in service providers. Specifically, we hypothesize that customer equity drivers influence trust in social robots and trust in service providers. We also propose that customer equity drivers influence customer experience quality in the context of social robots and that trust in social robots and trust in service providers mediate these relationships. The study used …

Performing Britishness: Identity And Popular Music Tribute Shows In Perth, Western Australia, Colin Outhwaite

Theses: Doctorates and Masters

This research investigates how and why individuals use popular music tribute shows to construct individual and collective identities within the British expatriate community in Perth, Western Australia. Popular music tribute shows involve recontextualised performances of past musical works and rely on shared first-hand or vicarious experiences between musicians and audiences. By examining how individuals and groups use music as a means for strengthening and maintaining cultural identity, the research investigates how musical activity is both a result and influence on the construction and perpetuation of a symbolic and temporal identity group that revolves around shared tastes and experiences.

Western Australian Mothers' Experiences Of Breastfeeding Support In Hospital After Birth: A Mixed Methods Study, Justine Van Der Watt

Theses: Doctorates and Masters

Background: The benefits of breastfeeding are well established for infants, mothers and the community, with the World Health Organisation recommending that infants be exclusively breastfed up to six months of age with an achievable goal of 70% globally. Yet in Australia only 15-37% may be reaching that goal. There have also been reported benefits and desires for mothers to be supported with their breastfeeding in order to increase and prolong breastfeeding duration and exclusivity, especially early after birth. However, there is limited research or literature exploring what experiences mothers are having with breastfeeding support, especially during their hospital admissions in …

Preparing For End Of Life In A New Country: A Grounded Theory Study On African Migrants Living In Australia, Gertrude Gondwe Phiri

Theses: Doctorates and Masters

African migration to Australia has grown in the past 20 to 25 years with many migrants staying permanently. This has led to migrants dying away from their birthplaces where family is responsible for end-of-life care planning for the individual. Although migrating to Australia is considered a great achievement, many migrants also experienced challenges. Previous studies have explored the barriers faced by migrants in relation to end-of-life care but have not addressed the cause of those challenges. This constructivist grounded theory study examines how migrants from three African countries, Malawi, Zambia, and Zimbabwe (MZZ) prepare for end-of-life in Australia. The study …

Excitatory Drive To Spinal Motoneurones Is Necessary For Serotonin To Modulate Motoneurone Excitability Via 5-Ht2 Receptors In Humans, Tyler T. Henderson, Janet L. Taylor, Jacob R. Thorstensen, Justin J. Kavanagh

Research outputs 2022 to 2026

Serotonin modulates corticospinal excitability, motoneurone firing rates and contractile strength via 5-HT2 receptors. However, the effects of these receptors on cortical and motoneurone excitability during voluntary contractions have not been explored in humans. Therefore, the purpose of this study was to investigate how 5-HT2 antagonism affects corticospinal and motoneuronal excitability with and without descending drive to motoneurones. Twelve individuals (aged 24 ± 4 years) participated in a double-blind, placebo-controlled, crossover study, whereby the 5-HT2 antagonist cyproheptadine was administered. Transcranial magnetic stimulation (TMS) was delivered to the motor cortex to produce motor evoked potentials (MEPs), and electrical stimulation at the cervicomedullary …

Parental Involvement In Children's Writing, Bronte Peta Kelso-Marsh

Theses: Doctorates and Masters

Research suggests that parental involvement is important for supporting children’s early literacy development. However, much of the existing research has focused on reading outcomes, and studies have seldom examined the influence of parental involvement on children’s writing outcomes. Learning to write is a complex process. Furthermore, although writing is a necessary skill required throughout schooling and the workforce, evidence from international studies suggests children’s writing performance is in decline. Theoretical models of writing have proposed the importance of contextual factors in shaping children’s writing acquisition and development, which may include parents. However, whilst previous research suggests parental involvement in supporting …

A Wreck Of Seabirds: Entrapment And Isolation Within The Australian Coastal Gothic Landscape, Karleah May Olson

Theses: Doctorates and Masters

This thesis explores the concepts of entrapment and isolation as they relate to the Australian Gothic literary mode and coastal landscapes. It does so through a creative work, a novel entitled A Wreck of Seabirds, and an accompanying exegesis, which examines these concepts alongside the shift of the Gothic to Australian landscapes and ultimately to coastal settings, and their representation in fiction. It examines ways in which elements and tropes of the Gothic are utilized in Australian Coastal fiction, particularly through depictions and metaphors of entrapment and isolation. A Wreck of Seabirds is an Australian Coastal Gothic novel set in …

Research outputs 2022 to 2026

γ-secretase processing of amyloid precursor protein (APP) has long been of interest in the pathological progression of Alzheimer's disease (AD) due to its role in the generation of amyloid- . The catalytic component of the enzyme is the presenilins of which there are two homologues, Presenilin-1 (PS1) and Presenilin-2 (PS2). The field has focussed on the PS1 form of this enzyme, as it is typically considered the more active at APP processing. However, much of this work has been completed without appropriate consideration of the specific levels of protein expression of PS1 and PS2. We propose that expression is an …

Cooper, Julie Hill, Desiree Silva, Anita M. Moorhead, Valerie Verhasselt, Joshua R. Lewis, Deborah Ireson, Jill R. Demirci, Talea Cotte, Kathryn Webb, Frances Patey, Therese A. O’Sullivan

Research outputs 2022 to 2026

Background: Although many mothers initiate breastfeeding, supplementation with human-milk substitutes (formula) during the birth hospitalization is common and has been associated with early breastfeeding cessation. Colostrum hand expressed in the last few weeks before birth, known as antenatal colostrum expression (ACE), can be used instead of human-milk substitutes. However, evidence is lacking on the efficacy of ACE on breastfeeding outcomes and in non-diabetic mothers. Methods and Planned Analysis: This multicenter stepped-wedge cluster (nested) randomized controlled trial aims to recruit 945 nulliparous pregnant individuals. The trial is conducted in two phases. During Phase 1, control group participants are under standard care. …

The Impact Of Reported Antibiotic Allergy In Paediatric Care And Antimicrobial Stewardship, Annabelle Arnold

Theses: Doctorates and Masters

Antimicrobial resistance is rising while new drug development declines, making antimicrobial stewardship crucial for optimizing use, preventing resistance, and improving patient outcomes. Antibiotics are vital for bacterial infections, but overuse and inappropriate prescribing have contributed to resistance. Although 5-35% of the global population reports β-lactam allergies, over 90% of reports are inaccurate. Adults have the highest prevalence; however, these labels are often acquired in childhood, with a notable increase among children recently. Unverified allergy labels hinder antimicrobial stewardship, leading to longer hospital stays, alternative prescribing, and a higher risk of adverse events.

This thesis sought to evaluate current evidence regarding …
