Best Practice Recommendations For Coaching Gymnasts To Avoid Burnout And Reframe Performance Anxiety, Clare A. Mccall

Theses: Doctorates and Masters

Gymnastics is deemed a psychologically demanding sport, with associated risk factors of burnout and performance anxiety. To date, relatively little research has explored the specific goal and perfectionistic processes of gymnasts, despite these risks. This body of work identified the specific goal-related constructs and perfectionistic orientation of young athletes and examined how these associated with burnout and performance anxiety. It comprised of two studies with a mixed methods design. The first study aimed to systematically review literature investigating how goal-related constructs and perfectionism associate with burnout and performance anxiety in young athletes. This review focused on summer and winter Olympic …

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 …

An Overview Of Blood-Based Biomarkers In Ad, Steve Pedrini

Theses: Doctorates and Masters

Alzheimer’s disease (AD) is the most common form of dementia in the elderly whose main neuropathological features are the presence of extracellular senile plaques in the brain and the intracellular accumulation of hyperphosphorylated tau filaments. However, a relatively cheap and non-invasive method for the diagnosis of AD remains elusive. Recent studies have indicated that cerebral biochemical changes take place decades before the clinical onset of the disease, but current methodologies, brain scan (PET amyloid imaging) and cerebrospinal fluid (CSF) analysis, are unsuited for community-wide screening. Brain scanning methods non-invasively assess amyloid load but are extremely expensive and cannot be used …

Woman-Centred Ethics: A Feminist Participatory Action Research, Katherine A. Buchanan

Theses: Doctorates and Masters

Background: The maternity system has a complexity of everyday ethical issues. The bioethical principles: non maleficence, beneficence justice and autonomy, that govern health care practice have been criticised as abstract, patriarchal and even rhetorical in maternity care practice (MacLellan, 2014) and consequently may be insufficient in guiding care of childbearing women. Midwifery-led care is guided by the International Confederation of Midwives International Code of Ethics, which considers more than the bioethical principles, such as the importance of relationship. Care ethics is a relational based feminist ethics first described by Gilligan (1983) and has been theorised as an alternate paradigm for …

Mining For Sleep Data: An Investigation Into The Sleep Of Fly-In Fly-Out Shift Workers In The Mining Industry And Potential Solutions, Gemma Maisey

Theses: Doctorates and Masters

Shift work in the mining industry is a risk factor for sleep loss leading to impaired alertness, which may adversely impact health and safety risks. This risk is being increasingly recognised by leaders and shift workers in the mining industry, however, there is limited knowledge available on the extent of sleep loss and other potential contributing factors. Furthermore, knowledge of the efficacy of individual interventions to assist shift workers to improve their sleep, and the management of risk at an organisational level is scarce. This PhD thesis involved three studies. The first two studies involved the recruitment of 88 shift …

Theses: Doctorates and Masters

Information on specific prognostic factors such as the association of body composition with survival and tailored strategies considering demographic and clinical factors as well as the influence of exercise tolerance and compliance are required to establish targeted exercise prescription in men with prostate cancer. As a result, the purpose of this doctoral research is to: (i) investigate the role of body composition on overall survival in men with prostate cancer; (ii) determine which type of exercise/physical activity and/or dietary intervention is most effective for improving body composition outcomes in this population; (iii) examine the demographic and clinical characteristics of resistance …

An Examination Of Kinanthropometric And Physical Injury Risk Factors In Elite Australian Football, Callum J. Mccaskie

Theses: Doctorates and Masters

Kinanthropometric assessment is an integral part of understanding an athlete’s physical profile and readiness for competition. This typically includes a variety of different assessments which serve to quantify body shape, proportion, and composition in a bid to understand human physiology. Common assessments include stature, body mass, limb ratios, body circumferences, body mass index, skinfold testing, body composition testing, and musculoskeletal morphological evaluations. Specifically, kinanthropometric evaluations have involved the characterisation of athletes according to sport, sex, competition level and playing position. While this has provided researchers and practitioners with greater insight into athletic phenotypes, more purposeful kinanthropometric assessments which focus on …

Towards Establishing A Fit-For-Purpose Regulatory Framework For Radiation Protection In Western Australia's Mining Industry: Evaluating Mine Worker Exposures To Naturally Occurring Radionuclides, Martin I. Ralph

Theses: Doctorates and Masters

Mining in the state of Western Australia (WA) formally commenced in the 1840s, and over the ensuing 180 years has evolved to be the epicentre of the Australian mining industry and a significant contributor to the national economy. The lithology of WA is replete with mineralisation that hosts uranium and “critical minerals” required for the global renewable energy sector. The state’s first uranium mine is under development, and high levels of activity are occurring in the state’s nascent critical minerals sector, with 168 WA-based companies pursuing rare earths-bearing minerals, 51 of which are actively drilling on their tenements.

WA’s mineral …

A Critical Control Approach To Preventing Fatalities In Construction, Roberta J. Selleck

Theses: Doctorates and Masters

Workplace fatalities continue to occur within the Australian construction industry at an unacceptably high rate. Most fatalities can be attributed to worker exposure to fatal energies while conducting high risk tasks in a dynamic work environment. Construction fatalities are usually single fatality events related to occupational safety hazards which are either not recognised by workers or not consistently controlled through existing safety practices. By comparison other resources industries have lower fatality rates because of their focus on identifying the controls and verification activities needed to address Major Accident Events (MAEs) and Principal Hazards in a manner that prevents fatalities.

The …

Preparing Providers For Advanced Life Support In The Prehospital Environment, David N. Reid

Theses: Doctorates and Masters

Out-of-hospital cardiac arrest is a leading cause of death and Ambulance Victoria estimated over 30,000 cardiac arrests occur outside of hospital each year in Australia (1, 2). When an out-of-hospital cardiac arrest occurs, first responders, paramedics or other clinicians attached to ambulance, industrial or aeromedical services are often the first providers on scene with the skills and equipment to implement advanced life support (ALS). Despite the essential role of prehospital advanced emergency care in the treatment of out-of-hospital cardiac arrest, at the time this research was commenced, ALS training courses had been designed for those responding to cardiac arrests in …

The Assessment Of Movement Demands And Neuromuscular Fatigue In Female Softball Players, Kathryn Cardwell

Theses: Doctorates and Masters

Softball has experienced an increase in worldwide popularity over the last 15 years, and it is expected to rise following the reinstatement of softball as an Olympic sport in 2021. Previous softball research has primarily focused on the biomechanical characteristics of its athletes. However, there is a current lack of research concerning the movement demands occurring in gameplay and the development of neuromuscular fatigue in softball players during sportspecific movements, training sessions, or in competition play. Prior research has demonstrated that a majority of power generated during a bat swing or overhand throw comes from the lower body, with the …

Unravelling The Potential Applications Of Extracellular Vesicles For The Clinical Management Of Melanoma Patients, Michael Edward Clark

Theses: Doctorates and Masters

Metastatic melanoma is the third most common cancer in Australia with global incidence increasing. After decades without effective systemic treatments for advanced melanoma, the advent of targeted and immune therapies has substantially improved patient survival. While this is encouraging, further research is needed as the majority of patients treated with targeted therapy ultimately develop drug resistance. Immunotherapy can achieve durable responses in many patients however, not all patients respond to current single or a combination of immune checkpoint inhibitors. Considering the cost and potential toxicities to patients being treated with these therapies, there is an urgent need to develop biomarkers …

The Coaches’ Eye: Exploring Coach Decision-Making During Talent Identification, Alexandra Hannah Roberts

Theses: Doctorates and Masters

For decades, researchers and practitioners interested in talent identification have discussed the coaches’ eye: the elusive ability that allows some coaches to ‘see’ qualities in an athlete that point to their talent or future potential. While there is significant anecdotal evidence of coaches who possess this ability, there is little empirical research supporting the validity or reliability of the coaches’ eye. Guided by ecological dynamics, this thesis employs mixed methodologies to explore the decision-making that underpins how high-level coaches identify talent in Olympic combat sports. These four studies captured the processes of thirty- four coaches during the talent identification process, …

Cost-Effectiveness Of Exercise Medicine For Prostate Cancer, Kim Edmunds

Theses: Doctorates and Masters

Background

Androgen deprivation therapy (ADT) is associated with numerous adverse effects that impact on quality of life and contribute further to the cost burden of prostate cancer (PCa) via treatment and supportive care. Exercise medicine is effective in slowing PCa progression, reversing treatment adverse effects and improving quality of life and survival of patients, however, no economic analyses have been conducted to determine whether exercise is cost-effective in this population.

Objectives

Firstly, to examine the adverse effects of ADT for PCa and the evidence supporting the use of exercise medicine in their management. Secondly, to conduct the first economic evaluations …

Drumbeat© For Arthritis “ A Shared Purpose” Rather Than A “Lonely Struggle”, Jannette Warhurst

Theses: Doctorates and Masters

Australia is regarded as a healthy nation, with life expectancy one of the highest in the world. Yet the latest National Health Survey tells a very different story. Almost 50% of Australians are now living with one or more chronic conditions, with arthritis and other musculoskeletal (MSK) conditions representing the most expensive chronic disease group in Australia. As the leading cause of chronic pain and second most common cause of disability and early retirement due to ill health in Australia, Arthritis is costing the economy over $7 billion a year, in addition to over $1.1 billion in extra welfare costs …

Investigation Of A Communication Enhanced Environment Model After Stroke: A Mixed Methods Before-And-After Pilot Study, Sarah D’Souza

Theses: Doctorates and Masters

Background: Aphasia is an acquired communication disorder that affects approximately 30% of first ever stroke survivors and persists one-year post-stroke in up to 61% of survivors. Aphasia impacts on all communication modalities with significant negative consequences for social participation, interpersonal relationships, autonomy, capacity to work and quality of life. It is recognised that the environment can influence neural remapping during early stroke recovery. However, patients with aphasia (PWA) following stroke have been observed to spend less than 30% of their day communicating and 44% of their day alone during their first weeks of in-patient rehabilitation. Inadequate opportunities for communication places …

Assessment Of The Clinical Validity Of Ctdna Analysis For Melanoma Management, Anda-Gabriela Marsavela

Theses: Doctorates and Masters

Metastatic melanoma is responsible for almost 80% of all skin cancer-related deaths and the incidence of people affected continues to rise worldwide. The emergence of targeted therapy and immune-checkpoint inhibitors has improved the clinical management of melanoma, but durable survival benefit is only seen in a minority of patients. The use of these very expensive systemic therapies on all appropriate patients also poses a high economic burden on health systems across numerous countries. Currently, surveillance for treatment failure is not optimal. Thus, reliable and accurate biomarkers of patient disease status are urgently required.

Circulating tumour DNA (ctDNA) analysis has emerged …

An Assessment Of Health Hazards Associated With The Use Of Water Mist Systems As A Cooling Intervention In Australia, Edmore Masaka

Theses: Doctorates and Masters

Water mist systems (WMS) installed and used for cooling ambient temperatures in public places fall within the category of premise plumbing. Premise plumbing refers to the water distribution networks that lie downstream of the water meter, and within buildings. The colonization of premise plumbing by opportunistic premise plumbing pathogens (OPPPs) such as Legionella pneumophila, Pseudomonas aeruginosa, Mycobacterium avium, Acanthamoeba and Naegleria fowleri is emerging as a challenge for public health and water quality management. Contrary to other premise plumbing features like showers and domestic taps that have been implicated in various waterborne infections, the health risks associated with WMS are …

An Exploration Of The Relationship Between Aphasia Therapy, Depression And Quality Of Life In Post-Stroke Patients After Rehabilitation At 12 And 26 Weeks After Stroke: A Verse Sub-Study, Alia Rashid Khan

Theses: Doctorates and Masters

Background: Depression is a common consequence of stroke, and people with aphasia (PWA) post-stroke have a higher risk of developing depression compared to stroke survivors without aphasia. However, current stroke interventions featuring aphasia therapy tend to neglect the effect of the treatment on mood. There is also a lack of evidence on the impact of stroke education and counselling on PWA in early stroke recovery. Additionally, the research on post-stroke depression often excludes or insufficiently describes PWA in study populations. The influence of direct aphasia therapy on depression in PWA is undetermined. This sub-study investigated: i) the effect of …

The Adherence To Group B Streptococcus Screening Guidelines Amongst Pregnant Women In Western Australia – A Quantitative Descriptive Analysis, Sabine Pangerl

Theses: Doctorates and Masters

Colonisation with Group B Streptococci (GBS) is a major risk factor for neonatal infection acquired via vertical transmission during pregnancy, labour, or birth, potentially resulting in significant morbidity and mortality. Universal screening at 35 – 37 weeks gestation for maternal GBS colonisation and the use of intrapartum antibiotic prophylaxis has resulted in substantial reductions in the burden of neonatal Early-Onset GBS Disease (EOGBSD). Women in Western Australia (WA) are offered GBS screening in pregnancy and intrapartum antibiotic prophylaxis. Anecdotal evidence suggests variations in viewpoints and thus low adherence to relevant clinical guidelines amongst midwives and pregnant women in the midwifery …

Does Accurate Data, Identifying Obese Patients Impact Nurse Safety And Hospital Finances?, Kim Mcclean

Theses: Doctorates and Masters

Healthcare staff who manage obese patients are at increased risk of sustaining patient handling injuries, and this risk is anticipated to intensify as projected Australian obesity rates increase to 42% by the year 2035 and obese patients admitted to hospitals also increase. High cost burdens to healthcare organisations will result due to increased funding requirements for bariatric risk management solutions and growing costs of workers’ compensation claims of injured staff. Five (5) studies explored if identification of obese patients impacts the safety of nurses and other healthcare staff who manage obese patients and investigated the accuracy of obesity data recorded …

Effects Of High-Intensity Position-Specific Drills On Physical And Technical-Skill Performance In Young Soccer Players, Cao Cuong Le

Theses: Doctorates and Masters

Soccer is the most widely played sport in the world, and physical preparation for soccer players has been extensively researched over the years. As the average intensity of a soccer match is close to 80-90% of maximal heart rate (HRmax), it is necessary to train at or above this intensity. Thus, high-intensity interval running and small-sided games are often used to improve aerobic capacity and repeated sprint ability (RSA). However, neither of these approaches consider positional variations in the frequency and type of specific technical skills required in real match situations. Thus, the purpose of this study was to investigate …

The Importance Of Telehealth In The Implementation Of Best Practice In Paediatric Burn Management By Non-Burn Specialist Clinicians, Tania Mcwilliams

Theses: Doctorates and Masters

Introduction: Burns are a leading cause of injury worldwide, yet the initial assessment and management of patients following burn injury is often performed by non-burn specialist clinicians. Using the Gilbert Behaviour Engineering Model as a framework, strategies were introduced to support these clinicians. A better understanding was needed, however, of the effectiveness of these strategies, and the experiences of clinicians who provide this initial care.

Aims: This study aims to contribute new knowledge related to paediatric burn care through the evaluation of a state-wide burns telehealth program in Western Australia; specifically, develop a deeper and more relevant understanding of a …

The Perceived Influence Of Grandparents’ Beliefs And Attitudes On Parents’ Breastfeeding Behaviour And Paediatric Vaccination Decisions, Shantha Premila Karthigesu

Theses: Doctorates and Masters

Human infants are highly dependent on their parents for a prolonged period of time. The resources required to raise a child cannot be provided by biological parents alone and requires the assistance of others, usually relatives. Grandparents among them, have played the most significant role. With increased life expectancy in Western, educated, industrialised, rich and democratic (WEIRD) societies, grandparents have come to the forefront as informal childcare providers. Although the influence of a child’s social environment on health has been well-studied, the influence of grandparents, specifically in regard to breastfeeding remains inconclusive, while grandparental influence on paediatric vaccinations has not …

The Impact Of Singing On Pulmonary Function And Quality Of Life In Patients With Muscular Dystrophy, Mia Simonette

Theses : Honours

Muscular dystrophy is a congenital disorder that results in progressive deterioration of muscle strength and function. The genetic disorder is caused by the absence of dystrophin protein which helps to keep muscle cells together, the absence of this protein causes muscles to become weak and fragile. Despite impairment of motor function and muscle strength, a major issue is the progressive impact on the respiratory muscles. Weak pulmonary function can lead to secondary issues such as atelectasis, decreased lung compliance, repeated infections, ineffective cough and ventilation-perfusion during sleep1. Respiratory failure is said to be the most common cause of death in …

Gait Entrainment In Coupled Oscillator Systems: Clarifying The Role Of Energy Optimization In Human Walking, Ryan T. Schroeder

Theses: Doctorates and Masters

Empirical evidence suggests that parameters of human gait (e.g. step frequency, step length) tend to minimize energy expenditure. However, it is unclear if individuals can adapt to dynamic environments in real time, i.e. continuously optimize energy expenditure, and to what extent. Two coupled oscillator systems were used to test the learned interactions of individuals within dynamic environments: (1) experienced farmworkers carrying oscillating loads on a flexible bamboo pole and (2) individuals walking on a treadmill while strapped to a mechatronics oscillator system providing periodic forces to the body. Reductionist trajectory optimization models predicted energy-minimizing gait interactions within the coupled oscillator …

Does Providing Pill Testing At Festivals Increase Intention To Use Ecstasy?, Sherri Lee Murphy

Theses : Honours

Calls to provide sanctioned pill testing (drug checking) at music festivals has met with resistance from most Australian governments due to a concern that such services would increase use of ecstasy and other drugs. To address an important gap in current knowledge, I investigated how a pill testing service might influence intention to use ecstasy. I also drew from the Theory of Planned Behaviour to examine what determinants of behaviour predict intention to use a pill testing service. Music festival attendees (N = 247) were presented with three hypothetical pill testing scenarios: The current legal circumstance where consumers only …
