The Performance Analysis Of Power Output In Professional Male Road Cyclists, Alan J. Metcalfe

Theses: Doctorates and Masters

Athletes regularly monitor exercise workload in an attempt to improve and maintain exercise performance. Within road cycling, workload is commonly measured using power output. Yet, it is plausible that power output during road cycling is influenced by several factors such as topography, road gradient or rider specialities. If these factors do influence power output they may influence quantification of workload demands. As such, the purpose of this thesis was to improve our understanding of external workload in professional road cycling and describe the factors which influence power output during performance analysis. Specifically, this thesis examined the power output within single …

The Lived Experience Of Non-Offending Mothers In Cases Of Intrafamilial Child Sexual Abuse: Towards A Preliminary Model Of Loss, Trauma And Recovery, Amanda Jean Thompson

Theses: Doctorates and Masters

The non-offending mother in cases of intrafamilial child sexual abuse has received limited empirical attention in comparative to the considerable body of literature examining victims and perpetrators of child sexual abuse. There is growing evidence that demonstrates that nonoffending mothers’ experience significant loss and trauma following the discovery of their children’s sexual victimisation by a family member, particularly where the perpetrators are their partners. An understanding of the non-offending mother’s experience is crucial to guiding statutory agencies and therapeutic interventions when working with these families. However, there is currently not a model or framework that conceptualises mothers’ post-discovery experience, and …

Unsupervised Monitoring Of An Elderly Person's Activities Of Daily Living Using Kinect Sensors And A Power Meter, Hossein Pazhoumand-Dar

Theses: Doctorates and Masters

The need for greater independence amongst the growing population of elderly people has made the concept of “ageing in place” an important area of research. Remote home monitoring strategies help the elderly deal with challenges involved in ageing in place and performing the activities of daily living (ADLs) independently. These monitoring approaches typically involve the use of several sensors, attached to the environment or person, in order to acquire data about the ADLs of the occupant being monitored.

Some key drawbacks associated with many of the ADL monitoring approaches proposed for the elderly living alone need to be addressed. These …

Food Insecurity And Fruit And Vegetable Consumption Among Regional And Remote Western Australian Children: Determinants, Prevalence And Predictors, Stephanie Louise Godrich

Theses: Doctorates and Masters

Living in a community with adequate availability of nutritious food, and the capacity to access and utilise it, are key food security determinants (FSD). However, inequities relating to these determinants exist between regional and remote Western Australian (WA) communities, particularly regarding fruit and vegetables (F&V). This negatively impacts vulnerable populations, especially children. In order to understand determinants, prevalence and predictors of F&V and food security (FS), three concepts were explored in this PhD; (1) F&V consumption among regional and remote WA children (including determinants of F&V consumption, quantities, types, varieties of F&V consumed); (2) FS among regional and remote WA …

Investigating Register Preferences In The Female Singer Of Contemporary Commercial Music, Tracey Cooke

Theses: Doctorates and Masters

The middle register is a region of the voice which has been discussed and disputed for many years in the disciplines of vocal pedagogy and voice science. This project, which was inspired by my own experience as a singing teacher in the private studio, seeks to investigate how female professional and pre-professional vocalists relate to their middle register. For the purposes of this dissertation, the middle register is assumed to refer to an area of the trained voice, or of the voice in training.

The project is composed of three studies. In Study One a pilot questionnaire was distributed to …

A Study Of Walking And Walkability Through A Spatial Justice/Spatial Practice Framework, In Maylands, Western Australia, Tina Askam

Theses: Doctorates and Masters

Recent studies have focused on the benefits of walking to health, wellbeing, creativity and social capital. However, apart from select ethnographic observations on walking as a distinct spatial practice (J. Lee & Ingold, 2006), there is a paucity of studies that investigate the ways in which walkers and space interact. Most importantly, there has been a distinct lack of attention to pedestrian perspectives and experiences in theory and in policy on walkability (Middleton, 2011, 2016).

Notable theorists have demonstrated the benefits of participatory walking practices as a conversive and convivial methodology for performance research (Myers, 2009), for intergenerational urban pedagogy …

The challenges associated with environmental monitoring such as the impact on the environment and the financial costs are problems we face when trying to conserve freshwater systems around the world. The need for precise and accurate results that are cost effective is important so that we can achieve our conservation goals.

The overall aim of this study was to explore Next-Generation - metabarcoding for the detection of feral and native freshwater fish species based on the DNA shed by individual organisms into the water column. Cytochrome c oxidase I (COI) primers were developed for this study using DNA from six …

A Sound Idea: An Investigation Into Accessible Video Game Design For The Deaf And Hard Of Hearing, Luke James Brook

Theses: Doctorates and Masters

A widely accepted, and incorrect, assumption towards hearing accessibility in video games is that deaf and hard of hearing (DHH) users are those who encounter the least barriers and are generally well catered for. Rapid advancement in video game technology has seen video game sound evolve from simple blips generated by internal circuitry to fully realised digital audio used to convey critical information. To accommodate the DHH, this information needs to be conveyed in an alternative manner. However, evidence suggests existing accessible design solutions for the DHH lack specificity and are insufficient. Thus, the inability to hear, or hear well, …

A Consumer-Based Brand Equity Model For The Luxury And Upscale Hotel Sector, Hairong Shan

Theses: Doctorates and Masters

Luxury and upscale hotels, in common with businesses in other service industries and more broadly, seek to develop a strong brand that will contribute to a long-term competitive advantage. However, research on consumer-based brand equity in luxury and upscale hotels is limited. Therefore, the current research, based on fundamental theories of brand equity development established in the packaged goods and the service industries including hotels, has developed a consumer-based brand equity model for the luxury and upscale hotel sector.

A mixed methods research design was employed. A qualitative study was first conducted using focus groups with the data being content …

Exploring The Experience Of Separation In Australia: Perspectives From Formerly Married And Cohabiting Parents, Sarah M. Barbas

Theses: Doctorates and Masters

The increase in separation and divorce rates during the 20th century brought with it many far-reaching social implications for all involved, sparking a high level of interest among researchers. Most research in this area has been approached from stress frameworks that have conceptualised separation and divorce as a stressful life transition that individuals must adjust to. Yet, attempts to understand separation and divorce to date have been dominated by quantitative methods that have resulted in a relatively static and objective understanding of this experience; particularly in Australia. Furthermore, although international rates of divorce are declining, rates of separation following cohabiting …

A Nested Environmental Approach To Typhoid Epidemiology In Central Division, Fiji, Aaron Jenkins

Theses: Doctorates and Masters

Many current disease threats involve interactions within and between nested subsystems of biological organisation. Typhoid fever is a serious disease threat in the South Pacific region, with Fiji reporting the highest annual number of cases, yet risk factors in this setting have been poorly studied. While localised behaviours have dominated perspectives on typhoid transmission, interactions between distal ecological conditions, conditions of the residential environment and localised behaviour deserve greater attention for their potential to influence transmission. This thesis demonstrates a nested approach to typhoid epidemiology using a fivefold methodology to explore how regional, river basin, residential, socio-cultural and behavioural subsystems …

Optimisation Of The Isolation And Identification Of Circulating Melanoma Cells, Anda-Gabriela Marsavela

Theses: Doctorates and Masters

Although melanoma is largely curable when detected in its earliest stages, it can metastasise to other tissues, drastically reducing survival rates. The most recent therapies used to treat metastatic melanoma are effective long-term in only 11 to 33% of patients. Our ability to monitor treatment failure is limited. New prognostic markers are urgently required to allow monitoring of treatment response and disease progression.

Circulating tumour cells (CTCs) are released into the bloodstream by the tumours within a patient, this being a key step in melanoma spread. Since CTCs can be detected in the blood of metastatic melanoma patients, these cells …

Investigating The Effects Of Changes In Light Quality On Different Life History Stages Of Seagrasses, Simone Strydom

Theses: Doctorates and Masters

Seagrass meadows provide crucial ecosystem services to the coastal zone but globally are threatened. Seagrass loss to date has mainly been attributed to anthropogenic activities that reduce light quantity, such as dredging, declining water quality from urban and agricultural run-off and eutrophication. However, light quality (wavelengths of light) is also altered by these anthropogenic stressors as well as natural events. This study consisted of three main components: (1) characterising light quality to which seagrasses are exposed across a local natural estuarine-ocean gradient and with a human impact pressure; (2) the influence of monochromatic light quality (blue λ=451 nm; green λ=522 …

Residence Time In Coastal Canopies, Maryam Abdolahpour

Theses: Doctorates and Masters

Aquatic canopies provide important ecosystem services such as improved water quality, oxygen flux, sediment stabilisation and trapping and recycling of nutrients. The ecological health of coastal canopies and the significant ecosystem services they provide depends largely on the continuous exchange of dissolved and particulate materials across the canopy boundaries. In coastal environments, where flow is typically wavedominated, vertical mixing is believed to be the dominant process controlling residence time and, therefore, exchange. However, experiments have shown that wave-driven flows over rough boundaries, such as canopies, generate strong onshore mean currents (75% of the orbital velocity far above the canopy) near …

Investigating The Practice And Capacity Of Paediatric Occupational Therapists To Promote The Physical Activity Levels Of Children In Western Australia, Sally Coombs

Theses: Doctorates and Masters

Reorientation of the Australian health care system to meet the increasing burden of disease requires health workers to develop a focus on disease prevention and health promotion. In Western Australia (WA) a priority area for the promotion of health involves increasing the physical activity levels (PAL) of children in accordance with Australia’s Physical Activity and Sedentary Behaviour Guidelines. There is substantial support in the literature for paediatric occupational therapists, who assist children to participate in a range of meaningful occupations, to incorporate the promotion of children’s PAL into their service. However, there is a dearth of research world-wide regarding occupational …

Nurse Staffing, Patient Falls And Medication Errors In Western Australian Hospitals: Is There A Relationship?, Ahmad Mousa

Theses: Doctorates and Masters

Background: According to the Australian Bureau of Statistics (2013) falls and medication errors in hospitals are among the first twenty leading causes of death. Research on the relationship between nurse staffing, patient falls, and medication errors are limited. Even scarcer are studies that examine this relationship on a nursing shift by shift and ward by ward basis, and no research exists on shift overlap periods and adverse patient outcomes.

Objective: This study examined whether there was a relationship between hospital inpatient falls and medication errors and nurse staffing on a shift by shift and ward by ward basis, including an …

An Assessment Of Nurses’ Experiences Of Work Related Stress Through Self-Reporting And Hair Cortisol Analysis, In A Metropolitan Hospital In Western Australia, Kim Oliver

Theses: Doctorates and Masters

The aim of this study was to assess how years of experience and practice area influence work related stress amongst 1,200 nurses employed in a metropolitan hospital environment in Western Australia. A combination of self-administered questionnaires and hair cortisol, an objective stress biomarker, was utilised to measure stress levels and to relate these to practice area, age and experience. Questionnaire results indicated that there was a higher level of perceived stress for 40% of this cohort of nurses; the study methodology was able to unearth noteworthy factors within a local WA nursing population that impacted on their perceived stress. These …

The proposed study will provide an increased understanding in a much-understudied area of how the Australian Indigenous community perceives physical activity and the beneficial effects for improving health outcomes.

The PhD will be made up of three studies:

1) To design an exercise prescription that is culturally appropriate and specifically addresses the major Indigenous health issues around metabolic syndrome.

The first will be a cross sectional study that surveys the motivators and barriers to physical activity within the Perth Noongar community. The results of this study will be used to enhance the intervention section of the PhD. It will provide …

The Effects Of Augmented Feedback On Pacing And Performance Of Elite Combat Athletes, Israel Halperin

Theses: Doctorates and Masters

Augmented feedback has been shown to improve performance and influence pacing in various physical activities. However, few studies have investigated its effects on performance and pacing in striking combat sports. Additionally, despite the plethora of studies examining the influence of feedback in untrained individuals, there is a lack of research examining the effects of such feedback in trained participants. Considering the important role of feedback in training and competition, the purpose of this thesis is to examine the effects of three different but inter-dependent methods of augmented feedback on performance of combat, and resistance trained athletes.

Study 1 examined the …

The Prevalence Of Twice Exceptional Students In The Gat Academic Programs: The Near Miss Phenomena, Lynne Ivicevic

Theses: Doctorates and Masters

Twice exceptional (TE) students often experience barriers to their participation in gifted academic programs that contribute to their marginalised status amongst the school gifted population. The estimated prevalence of TE students in gifted programs worldwide varies according to the location, identification means and definition, with little agreement reached between researchers in the field. This research was made up of three interrelated studies. Firstly, six years of longitudinal quantitative cohort data from the Western Australian Department of Education (DoE) database on selected students for the GAT programs including GAT Academic programs and TE students to determine TE prevalence. Secondly, disability prevalence …

Dry Land Strength And Power Training To Enhance Swimming In-Water Turn Performance, Julian Jones

Theses: Doctorates and Masters

Undertaking dry-land strength and power training to increase leg extensor power output is believed to increase a swimmer’s ability to start and turn during a swim race. Swimmers generally undertake dry-land strength and power training as part of their overall training regime to increase lower body force output and impulse, in order to improve both swim start and turning performance. Elite swimmers demonstrate faster swimming turn times that are potentially a result of having better strength-power characteristics than sub-elite swimmers. The aim of this research was to quantify differences in dry-land and swimming turn leg extensor force-time characteristics between elite …

Towards Active Ageing: A Comparative Study Of Experiences Of Older Ghanaians In Australia And Ghana, Daniel Doh

Theses: Doctorates and Masters

Population ageing has become a central feature of the 21st century, as most countries search for economically viable strategies to support and manage their ageing populations to live in a dignified way. In 2002, the World Health Organisation (WHO) proposed the active ageing policy framework to guide countries to develop policies that promote the quality of life for their older people. However, the interpretation and application of the active ageing model in the literature and policy discussions are inconclusive on the most important elements that promote the quality of life of older people. The discussions have largely focused on health …

Workplace Bullying: An Exploratory Study In Australian Academia, Manish Sharma

Theses: Doctorates and Masters

Workplace bullying is a behaviour which adversely affects individuals, organisations and the community at large. While substantial research has been conducted on workplace bullying in different work settings, limited research exists on this behaviour at universities; no comprehensive studies have to date been conducted in the context of Australian academia. This study therefore contributes through breaking new ground by exploring bullying within the increasingly corporatised and competitive Australian higher education sector. New Public Management (NPM) practices, diminished government funding, and limited resources risk transforming this sector into a full-fledged industry focused on corporate objectives to achieve operational profitability. Universities’ primary …

From Gd2o3suspension To Nanocomposite: Synthesis, Properties And Radiation Protection, Ly B. T. La

Theses: Doctorates and Masters

This study provides details for the design, preparation of an environmentally friendly, clinically safe and lightweight radiation protective shield made ofGd2O3/epoxy nanocomposite (Gd-nanocomposite) which is proposed as an alternative to traditional toxic lead (Pb)-based aprons for diagnostic X-ray protection. In theory, this particulate nanocomposite can possess significant features of both inorganic particles and organic polymeric matrices. However, in practice, its performance does not simply depend on the sum of the individual contributions of characteristics of the constituent phases but on the interaction of their inner interfaces and the homogeneous dispersion of inorganic particles in the polymer matrix.

The miniaturization of …

Ecology Of Savanna Ecosystems In Indonesia, Sutomo

Theses: Doctorates and Masters

Tropical savannas in South East Asia are important yet understudied ecosystems. In fact, the description of savanna is limited in the Indonesian Archipelago, a region which, based on climate alone, would be expected to have mostly forest. In this thesis, I compared and contrasted the vegetation characteristics of four savannas in the wetter part of the Indonesian archipelago (Java – Bali – Lombok) to understand how fire and grazing influence their dynamics, and searched for evidence of savanna origins, maintenance, invasion by exotic/woody species and possible ecosystem transitions. Vegetation surveys, remote sensing techniques and statistical models were used to spatially …

The Impact Of Communication Satisfaction On Paediatric Nurses’ Job Satisfaction And Intention To Stay, Gemma Doleman

Theses: Doctorates and Masters

Effective communication is the most central process within an organisation and is essential to organisational values, norms and expectations. There is a documented connection between job satisfaction, work commitment and organisational communication. However, nurses’ and nursing middle managers’ satisfaction with organisational communication has not been extensively studied in recent years and not at all among paediatric nurses. Therefore, the purpose of this study was to develop and test a theoretical model that examined paediatric nurses’ and middle managers’ satisfaction with organisational communication and the effect this has on paediatric nurses’ job satisfaction and intention to stay in their job.

Comparison In Muscle Activity Between The Back Squat, Romanian Deadlift And Barbell Hip Thrust During Hip Extension, Jose Delgado

Theses: Doctorates and Masters

Common resistance-training exercises such as back squat, Romanian deadlift (RDL), and hip thrust have been used by strength and conditioning specialists to target the musculature used during hip extension. Little is known about the differences in muscular activity of the hip extensors between these exercises, so it is not known which is the most effective as a hip extensor exercise. The primary purpose of this study was to compare muscle activity of several muscles during the high-bar back squat, RDL and barbell hip thrust, using men with a minimum of 1 year of lower-body resistance-training experience. Surface electromyography (EMG) was …

Older Indigent Women’S Economic Crimes: Subsuming Feminism In Favour Of A Human Rights Explanation, Patricia Joan Rhodes

Theses: Doctorates and Masters

Many people today believe the concept of gender inequality is outmoded, irrelevant and unnecessary in Western societies that are deemed egalitarian. As a consequence, feminism as a movement with gender equality at its core has often been proclaimed ‘dead’,a relic of the past. Feminist perspectives, nevertheless, have produced differing points of view about the sources of gender inequality affecting crime rates and criminal behaviour.

For the last 50 years or so, women and girls have been the subject of criminological research that has largely evolved from sociological perspectives and specifically from feminism. Although gender intersects with other social realities and …

Dialogue Not Diatribe: Methods For A Practice Of Socio-Humanitarian Playwriting, Siobhan Dow-Hall

Theses: Doctorates and Masters

This dissertation is the result of a practice-led research exploration of how creative writing practice may be expanded and developed with particular application to the writing of what I refer to as socio-humanitarian drama. I have developed this notion to promote discussion and consideration of specific issues of social justice and human rights within playwriting. While this practice-led research enlisted reflective practice in the task of developing and extending my own writing practice, this dissertation does also outline specific, practical modes of creative process, or exercises, that could be applied more broadly for others who may seek to develop their …
