Acute Physiological Effects And Perceived Enjoyment Of A Single Bout Of Aerobic Interval And Continuous Moderate-Intensity Cycling In Overweight And Obese Individuals, Fujie Koh

Theses: Doctorates and Masters

Aerobic interval training, a form of high intensity interval training, is commonly prescribed to both the general and clinical populations. However, the acute physiological effects from a single bout of aerobic interval session are not fully understood. In training studies, these acute physiological effects may confound actual training adaptations when they occur following the final training session [1]. Furthermore, while recreationally active men perceived aerobic interval training to be more enjoyable than continuous moderate-intensity exercise [2], the preference of overweight and obese individuals has not been extensively researched. Since overweight and obese individuals tend to have lower exercise tolerance, it …

Impact Of Nutrition On Cognition And Its Association With Blood And Brain Alzheimer Disease Related Biomarkers, Samantha Gardener

Theses: Doctorates and Masters

Alzheimer’s disease (AD), the most common form of senile dementia, currently affects over 35 million people worldwide. While there is no cure or effective treatment, early intervention programs hold considerable promise. Following particular dietary patterns represents one potential intervention strategy accessible to all.

Results from previous studies investigating the association of diet, cognition and biomarkers of AD are inconsistent: Positive results have been reported (1-7), whilst others have shown no associations. Prior to this thesis, no study has assessed the relationship of four dietary patterns to cognition, blood-based and neuroimaging biomarkers of AD in a large highly-characterised ageing cohort. Participants …

Space-Time Statistical Analysis Of Malaria Morbidity Incidence Cases In Ghana: A Geostatistical Modelling Approach, Simon K. Appiah

Theses: Doctorates and Masters

Malaria is one of the most prevalent and devastating health problems worldwide. It is a highly endemic disease in Ghana, which poses a major challenge to both the public health and socio-economic development of the country. Major factors accounting for this situation include variability in environmental conditions and lack of prevention services coupled with host of other socio-economic factors. Ghana’s National Malaria Control Programme (NMCP) risk assessment measures have been largely based on household surveys which provided inadequate data for accurate prediction of new incidence cases coupled with frequent incomplete monthly case reports. These raise concerns about annual estimates on …

Developing Effective Hospital Management Information Systems: A Technology Ecosystem Perspective, Christopher Bain

Theses: Doctorates and Masters

This thesis presents the results of the program of research performed in the completion of a Doctor of Philosophy (Business) entitled: Developing Effective Hospital Management Information Systems: A Technology Ecosystem Perspective.

The central contention of this thesis is that the current ecosystem models in the information technology (IT) and information systems (IS) literature can be extended and improved. In turn they can be better applied to the field of IS and the development and implementation of information systems. This research seeks to highlight an example of how these models can be extended, through an analysis of the specific context of …

Factors That Influence The Decision-Making Of An Integrated Rehabilitation Team When Choosing A Post-Hospital Discharge Destination For Survivors Of Stroke, Jessie M. Johnson

Theses: Doctorates and Masters

Stroke is one of the more disabling conditions which may result in the inability for survivors to care for themselves independently. Stroke survivors benefit most when they receive early onset assessment, treatment, and rehabilitation. Increasingly, stroke care in Canadian hospitals relies on an interdisciplinary rehabilitation team approach to provide immediate rehabilitation services and to make decisions about discharge destination for stroke survivors. Currently, there is little research on how interdisciplinary rehabilitation teams decide upon rehabilitation placements for stroke survivors or how individuals on the team, stroke survivors, or their families participate in and contribute to this decision. This research studied …

Comparison Of The Physical, Physiological And Perceptual Demands Of Small-Sided Games And Match Play In Professional Football Players, Stephen Hissey

Theses: Doctorates and Masters

The physical and technical requirements of a range of small-sided football (soccer) games (SSGs) have previously been examined in order to compare their requirements to competitive match play. SSGs are used to combine the technical, tactical and physical components of normal match play in training in order to make the training sessions specific to football. However, most previous research has focused on youth players and it is known that the playing patterns, and thus session outcomes, are different for elite players. Consequently, research examining elite players is required in order to improve our understanding of the use of SSGs in …

Plasma Insulin-Degrading Enzyme: Characterisation And Evaluation As A Potential Biomarker For Alzheimer's Disease, Michelle Tegg

Theses: Doctorates and Masters

Alzheimer’s disease (AD) is increasing in prevalence due to increasing lifespan and altered lifestyle. It is the fourth major cause of death in Western countries, resulting in significant economic and social impact (Von Strauss, et al., 1999; Goate, 1997). There are no blood biomarkers currently accepted for the diagnosis of AD, and the identification of suitable biomarkers would eventually reduce the necessity for invasive, expensive and slow diagnostic procedures, as well as facilitate prognostic studies. An AD blood test would decrease the need for delaying diagnosis due to ambivalent presentation, and allow therapeutic intervention to commence at an earlier …

Understanding And Building Resilience With Art: A Socio-Ecological Approach, Meagan Shand

Theses: Doctorates and Masters

Resilience is a widely researched phenomenon, it means different things to different people and is perceived and measured according to the theoretical lens being applied. The following thesis reviews the theoretical development of resilience that has led to contemporary understandings, to establish a platform for the research topic - understanding and building resilience with Art. Narrative research methods are combined with art processes to illuminate the stories of eight culturally diverse women participating in a community based mental health art program, in Western Australia. Fifteen resilience themes emerged from the collective experience, and are presented in a socio-ecological framework to …

Role Of Physical Exercise In Reducing Depression And Improving Mental Health In Cancer Survivors, Gregory Levin

Theses: Doctorates and Masters

Cancer survivors are more than twice as likely as the general population to suffer the debilitating effects of depression. This comorbid condition is associated with several negative consequences, such as reduction in compliance with cancer treatments, and hastened mortality. Recent research has examined the therapeutic effect of exercise on depression and reported excellent results of similar magnitude to those achieved with pharmacotherapy or psychological intervention. However, no research, to date, has examined the effectiveness of exercise on reducing depression in depressed cancer survivors. In order to address this important question this thesis reviewed previous literature in the area of cancer …

A Mixed Methods Obesity Prevention Intervention For Australian Children Aged 6-12 Years: Influence Of Parents Misperceptions About Food And Exercise On The Efficacy Of Educational Obesity Simulations, Claire Ellen Roockley

Theses: Doctorates and Masters

Increasing numbers of Australian children are being classified as overweight or obese. Given the health complications associated with excess weight, interventions to prevent children becoming overweight are crucial. Despite literature showing that parents shape their children’s food and exercise habits, no child obesity prevention programs have directly targeted parents. Moreover, although fear appeals have been used across several health promotion areas to change attitudes and behaviours, they have not been incorporated into an obesity preventive program. This study addressed these gaps by testing whether fear-based obesity simulations, targeted at parents as a tool for preventing childhood obesity, was more effective …

The Distinct Contributions Of Affective Distress And Personality To Memory Complaints Made In Older Adulthood, Matthew Robert Merema

Theses: Doctorates and Masters

Whilst a substantial amount of research has investigated the role of affective distress and features of personality in memory complaints made by older adults, little effort has been directed towards understanding their distinct contributions to complaints. Given considerable overlap between affective distress and features of personality, such evidence is necessary to inform theoretical frameworks pertaining to memory complaints and clarify results from other empirical studies examining these concepts. Consequently, the current study examined symptoms of depression and anxiety as predictors of memory complaints within the context of features of personality and other relevant contextual variables (i.e., age, gender, education, premorbid …

The Identity Of The Heart Patient In The Context Of The Gift Economy: Heartnet And Media Framing, Lynsey Uridge

Theses: Doctorates and Masters

This health communication research examines the identity levels of the heart patient on a therapeutic website HeartNET through an empirical investigation of site interactions as manifestations of a gift economy. The thesis also explores the media’s representation of heart health in both television and print.

This research utilised a longitudinal qualitative ethnographic and netnographic approach involving twenty-six participants who completed two in-depth interviews. The first one-on-one interview occurred during the early stages of the participants’ heart journey, explored their heart story and use of interactive technology for heart health support. The second interview occurred six to twelve months later, and …
