Activity Behavior And Physiological Profile Of Advanced-Stage Ovarian Cancer Survivors, Christelle Schofield

Theses: Doctorates and Masters

Background: Advanced-stage ovarian cancer survivors (OCS) often experience a multitude of disease symptoms and treatment-related side-effects. Additionally, most OCS are older, have comorbidities, are overweight or obese, and report being insufficiently physically active. Ovarian cancer survivors may benefit from exercise oncology interventions to reduce symptom-burden, manage comorbidities, minimize functional decline and maximize health-related quality of life (HRQoL). However, current knowledge gaps regarding the physiological characteristics of OCS throughout the entire survivorship spectrum challenge the development of tailored exercise interventions.

Purpose: The overall purpose of this thesis was to provide a more comprehensive physiological and activity behavior profile of post-treatment advanced-stage …

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 …

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 …

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 …

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 …

‘Fighting A Losing Battle’: A Glaserian Grounded Theory Of Midwives’ Workplace Stress, Sadie Margaret Geraghty

Theses: Doctorates and Masters

The development of the midwifery profession and the culture of childbirth are inevitably entwined from an historical perspective through to current day practice. Early written accounts describe the fifteenth century midwife as dealing with high maternal and child mortality rates, the invention of forceps, the rise of male obstetric practitioners, and the complex social and cultural changes of that era. The twenty-first century midwife faces challenges in Australia and worldwide, which are not dissimilar to our midwifery predecessors.

Midwifery clinical practice has become more complex due to the medicalisation of childbirth and 21st century lifestyles, which have contributed to a …

Development Of The Meal Framework: A Multiliteracies Approach To Engaging Adolescents In Nutrition Education, Samantha Lee Baker

Theses: Doctorates and Masters

Establishing and maintaining a healthy diet is integral in promoting optimal health, growth and development. Moreover, the food choices we make and dietary behaviours we adopt are a reflection of the multiple personal, interpersonal and environmental factors to which we are exposed. Consequently, changing food habits and dietary behaviour is complex and requires the implementation of multifaceted public health strategies. Comprehensive nutrition education provided to adolescents during their school years is one such approach.

Adolescence is a period of rapid psychological and physiological changes. At a socioemotional level, there is a decreased level of dependence on parents and a greater …

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 …

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 …

Effect Of A Neuromuscular Electrical Stimulation Muscle Strength Training Intervention On Muscle Force And Mass, Physical Health And Quality Of Life In People With Spinal Cord Injury, Vanesa Bochkezanian

Theses: Doctorates and Masters

Spinal cord injury (SCI) leads to significant deficits in muscle strength and mass, impacting negatively on physical health and quality of life (QoL). Physical rehabilitation techniques for people with SCI rely on constant updates and the accumulation of evidence regarding the efficacy of available and/or new physical interventions. Neuromuscular electrical stimulation (NMES) is already commonly used to activate skeletal muscles and subsequently reverse muscle atrophy, however NMES as a high-intensity “strength training” intervention appears to be a particularly promising technique for increasing muscle strength and mass and to subsequently improve physical health and quality of life (QoL) in people with …

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 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.

Employing …

The Relationship Between Physical Exercise And Cognition In Children With Typical Development And Neurodevelopmental Disorders, Beron Wei Zhong Tan

Theses: Doctorates and Masters

This research project sought to investigate the relationship between physical exercise and cognition in children with and without a neurodevelopmental condition. To achieve this aim, three approaches were undertaken to explore the exercise and cognition relationship. The first approach sought to understand the efficacy of exercise interventions on cognition in individuals with a neurodevelopmental disorder. The second approach was to understand the effectiveness of an exercise activity when compared to a cognitively-engaging tablet game activity on measures of implicit learning and attention in children with and without a neurodevelopmental condition. The third approach was to investigate if psychophysiological measures could …

The Human Factors Associated With Responding To Emergency Vehicles, Pauline Grant

Theses: Doctorates and Masters

Emergency vehicles undertake emergency driving, using lights and sirens, to move rapidly through traffic in response to situations where life and property are at risk. For the emergency driving to be effective, other motorists need to drive in a manner that facilitates their passage. Despite laws to support this, problematic encounters can result in emergency vehicles being unable to get through. The current research expanded on earlier exploratory research into motorists’ encounters with emergency vehicles (Grant, 2010) to examine psychological factors involved with motorists’ responses to emergency vehicles. A construct validity approach was used to develop a scale …

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 …

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 …

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 …

Chinese Nursing Students At Australian Universities: A Narrative Inquiry Into Their Motivation, Learning Experience, And Future Career Planning, Carol Chungfeng Wang

Theses: Doctorates and Masters

This study presents a narrative inquiry of Chinese nursing students at Australian universities in order to examine these students’ motivations, learning experiences and future career planning. Australia seeks to attract international nursing students from China to maintain its economic advantage and alleviate its projected nursing shortage. In contrast, China desperately needs its best and brightest citizens who have trained abroad as nurses to return to China in order to cope with its current challenges in the healthcare system and nursing education. Little is known about the underlying factors that motivate Chinese nursing students to study in Australia, these students’ learning …
