What Drives Food Insecurity In Western Australia? How The Perceptions Of People At Risk Differ To Those Of Stakeholders, Lucy M. Butcher, Maria M. Ryan, Therese A. O'Sullivan, Johnny Lo, Amanda Devine

Research outputs 2014 to 2021

Food insecurity is considered a “wicked” problem due to the highly complex and at times undefined casual factors. Although many stakeholders are working to address the problem, a possible divergence exists between their views on food insecurity and those of the people who are actually experiencing the problem. The purpose of this study was to investigate whether there was a difference between the opinions of those “at risk” and stakeholders. A total of seven focus groups (two stakeholder groups n = 10, five “at-risk” groups n = 34) and three interviews (stakeholders n = 3) were conducted to ascertain perceptions. …

Social Impacts Of Occupational Heat Stress And Adaptation Strategies Of Workers: A Narrative Synthesis Of The Literature, Victor Fannam Nunfam, Kwadwo Adusei-Asante, Eddie John Van Etten, Jacques Oosthuizen, Kwasi Frimpong

Research outputs 2014 to 2021

Dimensions of risks and impacts of occupational heat stress due to climate change on workers' health and safety, productivity, and social well-being are significantly deleterious. Aside from empirical evidence, no systematic review exists for policy development and decision making in managing occupation heat stress impacts and adaptation strategies of workers. This study sought to synthesise evidence on the social impacts of occupational heat stress and adaptation strategies of workers. From a review of existing literature, eight categories were obtained from 25 studies and grouped into three syntheses: (1) awareness of occupational heat stress, (2) social impacts of occupational heat stress …

Sequestration Of Macroalgal Carbon: The Elephant In The Blue Carbon Room, Dorte Krause-Jensen, Paul Lavery, Oscar Serrano, Nu´Ria Marba, Pere Masque´, Carlos M. Duarte

Research outputs 2014 to 2021

Macroalgae form the most extensive and productive benthic marine vegetated habitats globally but their inclusion in Blue Carbon (BC) strategies remains controversial. We review the arguments offered to reject or include macroalgae in the BC framework, and identify the challenges that have precluded macroalgae from being incorporated so far. Evidence that macroalgae support significant carbon burial is compelling. The carbon they supply to sediment stocks in angiosperm BC habitats is already included in current assessments, so that macroalgae are de facto recognized as important donors of BC. The key challenges are (i) documenting macroalgal carbon sequestered beyond BC habitat, (ii) …

Children’S Perceptions Of The Importance And Value Of Reading, Margaret K. Merga, Saiyidi Mat Roni

Research outputs 2014 to 2021

Fostering children’s engagement in regular recreational reading beyond independent skill acquisition is beneficial to promote continued literacy engagement. Regular recreational reading is associated with both literacy skill acquisition and maintenance across the life span. Children’s perceptions of the importance and value of reading can influence their motivation to read. However, it is not currently known if children continue to perceive the value of reading beyond the period of independent reading skill acquisition. Findings from a sample of 997 older elementary children indicate that some children may not recognise the value of reading beyond independent reading skill acquisition. This is particularly …

A ‘Better’ Education: An Examination Of The Utility Of Boarding School For Indigenous Secondary Students In Western Australia, Mary-Anne Macdonald, Eyal Gringart, Terry Ngarritjan Kessaris, Martin Cooper, Jan Gray

Research outputs 2014 to 2021

Over the past 10 years, great improvements have been observed in the Year 12 attainment rate of Indigenous Australians. This has been due, in part, to government funding of programmes aimed at improving education opportunity for Indigenous Australian students, including funding of scholarships for students from remote areas to attend boarding schools. The current qualitative study investigated the perspectives of school leaders and Indigenous secondary students across the Australian state of Western Australia, on the utility and impact of this boarding provision. Students identified that boarding education allowed them to achieve a dual goal of meaningful career pathways and improved …

A Simplified Simulation Model To Estimate The Storage Length Of The Right-Turn Lane In Left-Hand Traffic At Signalised Intersections For Different Signal Phases And Cycle Timings, Noura Ishak-Thomas, Steven J. Richardson, Sanjay K. Shukla

Research outputs 2014 to 2021

Introduction:

A large number of the current guidelines and models are used to estimate the right-turn lane (RTL) length in left-hand traffic at signalised intersections under split phase, in which the movement of traffic in the right-turn lane and through lane happen concurrently. There is a need to examine other phase types and timings as a part of the RTL design. This is particularly significant in the case of established intersections that cannot be modified due to physical constraints.

Methods:

A MATLAB based simulation programme was developed to provide an estimate of the right-turn lane storage length for different traffic …

An Entropy-Histogram Approach For Image Similarity And Face Recognition, Mohammed Aljanabi, Zahir Hussain, Song F. Lu

Research outputs 2014 to 2021

Image similarity and image recognition are modern and rapidly growing technologies because of their wide use in the field of digital image processing. It is possible to recognize the face image of a specific person by finding the similarity between the images of the same person face and this is what we will address in detail in this paper. In this paper, we designed two new measures for image similarity and image recognition simultaneously. The proposed measures are based mainly on a combination of information theory and joint histogram. Information theory has a high capability to predict the relationship between …

Research outputs 2014 to 2021

Background:

Neoadjuvant chemoradiation treatment (CRT) in rectal cancer patients is associated with a reduction in physical capacity, lean mass and increased fatigue. As a countermeasure to these treatment-related adverse effects, we examined the feasibility and preliminary efficacy of a 10-week exercise program during CRT.

Methods:

Ten rectal cancer patients (7 men, aged 27-70 years, body mass index = 26.4 ± 3.8 kg/m2) receiving CRT undertook supervised resistance and aerobic exercise twice weekly. Assessments were undertaken pre- and post-intervention for upper and lower body muscle strength by 1-RM, muscle endurance, physical performance tests, body composition by dual X-ray absorptiometry, quality of …

An Investigation Of Mobile Phone Use While Driving: An Application Of The Theory Of Planned Behavior, Sokunthea Kruy

Theses: Doctorates and Masters

Mobile phone use while driving has been an emerging issue for road safety in recent years. The development of new technology has meant that users are more connected to their devices than ever before. This has led to use while driving despite the illegality of this behaviour. In this research, three mobile phone use behaviours were investigated: making/receiving calls; creating/sending text messages, and accessing social media. Through application of the Theory of Planned Behavior (TPB), an online survey was developed. Five hundred and fifty-nine university students including 193 young respondents (aged 17 – 25) responded to investigate attitudes, subjective norms, …

The Mechanics Of Front Leg Loading During Cricket Fast Bowling: Delivery Variations, Spell Demands, And The Effects Of Strength Training, Samuel J. Callaghan

Theses: Doctorates and Masters

The goal of fast bowling in cricket is to dismiss a batsman for as few runs as possible. To assist this goal, fast bowlers will attempt to maximise ball release velocity (BRV) to decrease the decision-making and stroke execution time of the opposing batsmen. Fast bowlers will also employ various delivery lengths (i.e. short, good and full) to assist in affecting a batsman’s stroke execution.

Several issues remain to be addressed with regards to the biomechanical assessment of fast bowling. This is particularly evident when analysing fast bowling performance (i.e. BRV), the implications of front foot loading (i.e. vertical and …

Neuromuscular Factors Contributing To Reductions In Muscle Force After Repeated, High-Intensity Muscular Efforts, Benjamin J. C. Kirk

Theses: Doctorates and Masters

Fatigue can accumulate sufficiently to limit muscular force production during repeated, forceful muscle contractions, including those that occur in the occupational, clinical and athletic settings. Fatigue during such efforts is likely to result from disturbances to multiple processes in the nervous system and muscle. However, previous research examining the mechanisms underpinning fatigue have typically required subjects to perform low-level constant-force contractions or to repeat maximal efforts in a single set format. Such tasks do not translate well to occupational, daily living or athletic situations where high-intensity, yet submaximal, repeated efforts may be performed in work bouts (or sets) with brief …

Within-Fire Patchiness Associated With Prescribed Burning In The Northern Jarrah Forests Of Western Australia, Zigourney Nielsen

Theses: Doctorates and Masters

There is growing understanding of the importance of landscape mosaics and heterogeneity for biodiversity outcomes in Western Australia. However, there is limited information on the patchiness (spatial configuration of unburnt and burnt patches which occur at a range of spatial scales) within the perimeter of a single prescribed burn. Of particular concern is the idea that prescribed burning operations, carried out under very restricted weather and environmental conditions, can lead to structural and floristic homogenization of the area within a burn perimeter. This may be evident as reduced post-fire vegetation patchiness. Western Australian Jarrah (Eucalyptus marginata) forests are managed to …

Holistic Health: Shaping Women’S Experiences Of Positive Body Image, Helen Elizabeth Monks

Theses: Doctorates and Masters

This PhD thesis seeks to contribute to a nuanced understanding of positive body image and how it is expressed among a group of women participating in holistic health culture in a modern Western society. Qualitative data were collected from in-depth ethnographic interviews with 25 women in Perth, Western Australia, to illuminate an understanding of their holistic health beliefs and practices, perceptions of appearance and health ideals, as well as their understandings of positive body image. Thematic analysis of the data through Nvivo revealed several overarching themes, demonstrating how certain aspects of holistic health culture may encourage or dissuade the development …

Ghanaian Parents’ Experiences Of Caring For Their Preterm Infants After Discharge From The Neonatal Unit - A Narrative Inquiry Study, Esther Abena Adama

Theses: Doctorates and Masters

The care of preterm infants is associated with stress. In the busy neonatal unit where highly skilled healthcare workers are always present, parents have reported being stressed when caring for their preterm infants in the neonatal unit. In Ghana, preterm birth is the highest cause of neonatal mortality with 70% of these morbidities and mortalities occurring in the community. Yet to date, no study in Ghana has explored how parents experience their care giving role after discharge from the neonatal unit into the community.

This study explored the experiences of caring for preterm infants in the neonatal unit and after …

Teacher Identity Construction In A Tesol Graduate Certificate Of Education In Western Australia, Arman Abednia

Theses: Doctorates and Masters

This research project explored the potential of a second language teacher education course for fostering teacher identity negotiation. It was found that classroom conversations provided a rich space for teacher identity negotiation; however, no substantial changes were observed in most aspects of their identities during the course, except for a growth in a few teachers’ selfconfidence. The implications are that conducting teacher education in an interactive manner is highly beneficial, but deeper engagement with practice of teaching is recommended. These insights should facilitate positive outcomes for teacher education programs.

A Framework For Development Of Android Mobile Electronic Prescription Transfer Applications In Compliance With Security Requirements Mandated By The Australian Healthcare Industry, Kyaw Kyaw Htat

Theses: Doctorates and Masters

This thesis investigates mobile electronic transfer of prescription (ETP) in compliance with the security requirements mandated by the Australian healthcare industry and proposes a framework for the development of an Android mobile electronic prescription transfer application. Furthermore, and based upon the findings and knowledge from constructing this framework, another framework is also derived for assessing Android mobile ETP applications for their security compliance.

The centralised exchange model-based ETP solution currently used in the Australian healthcare industry is an expensive solution for on-going use. With challenges such as an aging population and the rising burden of chronic disease, the cost of …

Genetic Determinants Of Rates Of Cognitive Decline In Preclinical Alzheimer’S Disease, Tenielle L. S. Porter

Theses: Doctorates and Masters

In 2015 the number of people worldwide living with Dementia was 46.8 million, with approximately 50-75% of these cases being clinically defined as Alzheimer’s disease (AD). Despite extensive efforts, clinical trials have so far failed to yield a treatment that successfully addresses the underlying cause of AD. This lack of treatment has been suggested, in part, to be a result of late stage of intervention in current clinical trial design. For this reason, greater focus has been placed on preclinical trials and in turn both the identification of individuals at-risk for AD and, amongst these, those that are expected to …

The Beloved: A Documentary Film On The History And Aftermath Of Fremantle’S Rajneesh Sannyasin Community – And – Hidden Realities: Transcendental Structures In Documentary Film: An Exegesis, Joseph London

Theses: Doctorates and Masters

This creative work and its associated exegesis examines the concept of what I have termed a ‘transcendental structure’ in relation to a documentary film form, and what outcomes, specific to a non-fiction mode of representation, result from the application of this structure. A transcendental structure in film has a long history of investigation and interpretation in narrative fiction film theory and practice, but is substantially absent from documentary scholarship. The topic appears, in different forms, in the critical writings of Zavattini (1940), Bazin (1946), Pasolini (1965), Schrader (1972), Deleuze (1985), and more recently, Perez (1998) and Minghelli (2016). All of …

Gender Differences In Physical Performance Characteristics Of Competitive Surfers, Joanna Parsonage

Theses: Doctorates and Masters

Competitive surfing is judged on the performance and complexity of innovative and progressive manoeuvres. As such, surfers require the physical attributes of strength and power in both the upper and lower-body in order to facilitate performance. To date, there remains limited research pertaining to the physical performance characteristics of competitive female surfers, making it difficult to quantify the current gender gap in performance attributes. Therefore, the purpose of this thesis was fivefold: (1) to describe and compare the gender differences in physical performance characteristics of competitive surfers; (2) to investigate the reliability and validity of the isometric push-up (IPU), dynamic …

No-One Was Watching: A Collection Of Short Fiction And Stories Beyond The Gates: An Exegesis, Ann Elizabeth Horner

Theses: Doctorates and Masters

This research project asserts the primacy of creative practice as a key method of enquiry and explores how fictional stories, re-imagined from historical events of the mid-twentieth century, may provide different ways of viewing a world which was inhabited by once-silenced children, now known as the ‘forgotten Australians’. To this end, the thesis is made up of a creative component in the form of a book-length collection of short fiction that is accompanied by a critical component positioning the thesis contextually, theoretically and methodologically. The research reveals overwhelming evidence of a culture of endemic abuse within Australian child welfare organisations …

Changes to education policies and the creation of new curricula in Western Australia (WA), such as the new WA Humanities and Social Sciences (HASS) Curriculum in 2017, may place external pressure on teachers as they transition from existing to new curricula. The aim of this interpretivist study was to investigate the transition to the new WA HASS Curriculum in 2017. The experiences and perspectives of the school leaders and teachers in Pre-primary, Year One and Year Two (PP to Y2) in two Perth metropolitan independent schools was explored. The preparation undertaken by the early childhood teachers and leaders, and the …

Vital Performance: Culture, Worldview, And Romanticist Performance Practice With Application In Franz Liszt’S Consolations And Années De Pèlerinage Première Année, Andrew John Snedden

Theses: Doctorates and Masters

This thesis examines issues of historical performance in the piano music of Franz Liszt, positing cultural exegesis as an overlooked source of evidence. Philosophical biases underlying mainstream C20th performance approaches (and their inhibiting potential) are discussed. A detailed reconstruction of Romanticist style is made with attention to primary sources, including historical recordings. A nomenclature for score annotation and an analytical paradigm for identification and application of Romanticist performance characteristics are proposed. These are experimentally applied, referencing exegetical insights, in Liszt’s Consolations and Années de Pèlerinage: Première Année through annotated scores and studio recordings on an 1860’s Érard grand

The Cryopreservation Of Human Semen, And Subsequent Evaluation Of A Commercially-Available Device To Isolate Motile Sperm, Callum Andrew Robinson

Theses: Doctorates and Masters

The cryopreservation of human semen is a vital asset in assisted reproductive technologies (ART). Although advances have been in the freezing of sperm, further refinement is both necessary and ongoing. Computer-assisted semen analysis (CASA) has been increasingly utilised in both research and diagnostic however there are a range of variables that must first be controlled in order to produce reliable measurements. Following thawing, sperm must be isolated from both the original seminal plasma and the cryoprotectants; the two most used isolation methods include density gradient centrifugation (DGC) and the swim-up method.

The present thesis sought to investigate the following areas …

Aims: The primary aim of this thesis was to provide evidence that renal nurses could safely and efficiently perform IVC-US on haemodialysis patients to obtain objective assessment of intravascular volume status and potentially reduce adverse events and morbidity. The secondary aims for this study were: (1) conduct a systematic literature review to identify evidence if renal nurses have previously used this method for intravascular volume assessment; (2) teach a renal nurse through a staged educational programme, …

Optimisation Of Stand-Alone Hybrid Energy Systems For Power And Thermal Loads, Barun Kumar Das

Theses: Doctorates and Masters

Stand-alone hybrid energy systems are an attractive option for remote communities without a connection to a main power grid. However, the intermittent nature of solar and other renewable sources adversely affects the reliability with which these systems respond to load demands. Hybridisation, achieved by combining renewables with combustion-based supplementary prime movers, improves the ability to meet electric load requirements. In addition, the waste heat generated from backup Internal Combustion Engines or Micro Gas Turbines can be used to satisfy local heating and cooling loads. As a result, there is an expectation that the overall efficiency and Greenhouse Gas Emissions of …

Residents’ Perceptions Of Geotourism In Qeshm Island Unesco Global Geopark, Iran, Shahrzad Khodayar

Theses: Doctorates and Masters

While much scholarly attention has explored the impacts of tourism behaviour on a destination, little is known about the effects of geotourism activities on host communities. Geotourism is a type of tourism based on geological features. It has been variously defined as a tourism with a ‘geological’ or ‘geographical’ orientation. This study addresses this gap in the literature by exploring residents’ perceptions of the impacts of geotourism development in the Qeshm UNESCO Global Geopark in the Persian Gulf in Iran. Qeshm Geopark has a sensitive environment as well as a strict traditional culture and it receives about 3 million visitors …

Antibiotic Resistance In Gram Negative Bacteria Isolated From Fish Sold In Western Australia, Hannah Kathleen Robinson

Theses: Doctorates and Masters

Background Information The global misuse and overuse of antibiotics in human medicine and the animal production industry is contributing to the development of antibiotic resistance in bacteria. This is a serious threat to modern medicine and public health. Antibiotic resistant organisms can cause severe infections in humans which are difficult to treat, and in some cases impossible to resolve which can lead to premature death. Several studies have been conducted across the globe to assess the use of antibiotics in the seafood industry and the associated health risks, however, limited studies have recently explored this risk in an Australian setting. …
