A number of key databases, speech pathology journals and grey literature sources were searched to obtain articles relevant to the research aims. Two researchers independently rated articles for inclusion as well as methodological quality using the …

Searching For Health Information On The Internet : The Experiences Of Western Australian Adolescents, Lee-Anne Martins

Theses : Honours

Adolescents readily engage in online entertainment pursuits, however, it is their online social activities and health information searches that encourage psychosocial development and influence identity formation and autonomy. Considerable research has been completed on various aspects of adolescents’ encounters with online health information (for example, see Percheski & Hargittai, 2011), yet minimal research has been conducted using Australian adolescents. This study extends existing research utilising Western Australian adolescents who have used the Internet to obtain health information. The areas explored include how Western Australian adolescents search for online health information, by means of which devices, and their experiences of using …

Scripting Therapeutic Screen Stories : Animating The Healing Potential Of Film Narratives, Andrew Levett

Theses : Honours

Beyond entertainment, animated narratives can potentially induce psychological healing, termed “individuation.” Stories exist in many forms, like literature, film and conversation, as well as in the human mind, or “psyche.” These “self-narratives” use life experience to shape consciousness. Therefore, effective storytelling based on archetypal myths can restructure the psyche. Film narratives communicate meaning through symbols, termed “textual cues”, while screenwriters employ specific templates, which organise story information into familiar structures. These guide audiences towards predetermined meaning. Through bibliotherapy, which is the use of literature for therapeutic purposes, audiences project their unconscious content onto narrative components that resonate with it. Ego-consciousness …

Women Who Stutter : Experiences Of Developing Self-Management And Quality Of Life, Katherine Milton

Theses : Honours

Background and Purpose: Research suggests that stuttering can impact an individual’s quality of life and how they perceive themselves in interactions with others. As a larger proportion of adults who stutter are men, limited research is available regarding the specific experiences of women who stutter (WWS). Existent literature regarding WWS was mainly published in the 1970s -1980s and may no longer represent current issues. This study aimed to explore the current influences on quality of life, perception of stuttering, self-management strategies, and gender issues experienced by WWS.

Methods and Procedures: This grounded theory study used a convenience sample of eight …

Self-Efficacy And Nutrition Knowledge Of Parents In Western Australia, Karen Lombardi

Theses : Honours

Background: Poor dietary choices and increasingly sedentary lifestyles mean childhood obesity is an increasing problem. Parents have the capacity to significantly affect the food choice of children; therefore by improving their self-efficacy, their nutrition knowledge, attitudes and behaviour, and by providing access to sound nutritional information, the health of children may be improved.

Purpose: This research sought to gather preliminary information required to inform the development of nutrition education materials for parents, which will parallel those currently under development for teaching children in schools as part of the Australian curriculum. Research has demonstrated that while educating children about healthy eating …

Speech And Language Processes In Children Who Stutter Compared To Those Who Do Not Within An Oral Narrative Task, Sarah Pillar

Theses : Honours

Background and Purpose: Language ability in children who stutter has been linked to the occurrence of stuttering, however, the validity of research supporting this connection has been recently questioned. Previous research, within this area, has been limited by methodological confounds, such as lack of appropriately matched comparison groups, and the use of measures with insufficient sensitivity to potentially examine the subtle differences between children who stutter (CWS) and children who do not stutter (CWNS). Frequent hesitations or pauses are defining characteristics of the speech of people who stutter. However, little is known about the nature and frequency of the pauses …

The Stigmatisation Of Alcohol And Other Drug Services, Kim Eaton

Theses : Honours

People who are dependent on alcohol and other drugs (AOD) are often stigmatised. Evidence suggests that the people who provide AOD users with health and welfare supports also feel the stigma experienced by users. However, the literature supporting this proposition consists of inadvertent findings and findings generalised from other populations. A systematic review of the limited research into stigma experienced by people working in the AOD field was conducted. This involved a multi-phase database, journal and website search, with additional hand searching of relevant referenced articles. Overall, 146 relevant studies were found, 38 of which were applicable to this review, …

Analysing A New Mobile Bilateral Audiology Test For Children, Luke J. Brook

Theses : Honours

Hearing loss in Australian children, primarily Aboriginal and Torres Strait Islanders, is a growing concern for the Australian public health sector. In certain rural communities up to 90 per cent of children have been found to experience some form of hearing loss. Although hearing loss can be the result of a number of different causes, including congenital influences, the most common cause of hearing loss in Australian children is attributed to a common middle ear infection, otitis media.

To address the issue, numerous solutions have been proposed, tested and implemented, although the problem persists due to geographic, environmental and cultural …

Improving Functional Outcomes For Children And Adolescents With Anxiety Related Disorders Through Occupational Thrapy : A Narrative Review ; Perceptions Of The Role Of Occupational Therapy In Community Child And Adolescent Mental Health Services (Camhs), Paula J. Anderson

Theses : Honours

Background/Aim: Children and adolescents experiencing anxiety find it challenging to maintain optimal occupational performance, thus the specific role of occupational therapy in the management of anxiety requires investigation. This narrative review examines the current available literature surrounding the use of occupational therapy approaches for children and adolescents experiencing anxiety.

Methods: Academic journals as well as a variety of sources were considered, due to the paucity of literature surrounding this topic. Articles were included if they discussed the occupational therapy role in treatment of children experiencing anxiety symptoms, including anxiety related disorders such as post traumatic stress disorder (PTSD) and obsessive …

The Use Of The Communication Checklist - Adult (Cc-A) For Assessing The Communication Abilities Of Individuals Post Traumatic Brain Injury, David B. Fitzgerald

Theses : Honours

Background and aims: Standardised and non-standardised assessments are used in speech pathology to evaluate an individual’s communication abilities post traumatic brain injury (TBI; e.g. Turkstra et al., 2005b). However, valid, reliable and norm-referenced standardised assessments that examine functional communication abilities of individuals post TBI outside of the clinical environment are limited. This study sought to investigate the validity of the Communication Checklist - Adults (CC-A; Whitehouse & Bishop, 2009), a caregiver questionnaire that assesses the communication abilities of individuals post TBI.

Method: The project recruited 14 participants post TBI with varying communicative impairment severities. Each participant completed a routine communication …

The Influence Of External Loading And Speed Of Movement On Muscle-Tendon Unit Behaviour And Its Implications For Training, Jacob Earp

Theses: Doctorates and Masters

In this thesis great emphasis has been placed on vastus lateralis (VL) muscle-tendon unit (MTU) structure, behaviour/movement and adaptation. Of particular interest was how external loading and movement speed influence these variables. In the first study (Chapter 3) we developed a new methodology by which electromyography (EMG) could be normalised during large range of motion knee extensions. This methodology was then used as part of a larger study, which investigated how external loading influenced the interaction of muscle and tendon (MTU behaviour) during stretch shortening cycle isoinertial knee extensions, and how muscle activity and intrinsic tendon force (Ft) influenced MTU …

Pediatric Medical Traumatic Stress : The Impact On Children, Parents And Staff, Sarah Mcgarry

Theses: Doctorates and Masters

Burns are one of the most painful and traumatising injuries an individual can sustain and constitute a serious global health threat to children. Despite the magnitude of this public health problem, little research has examined the psychological burden of these injuries. This study used a mixed-methods approach to investigate the effect of paediatric medical trauma on children who have sustained a burn, their parents and the healthcare professionals caring for these patients. The paediatric medical traumatic stress model provided a theoretical framework for this study.

Firstly, this study aimed to gain an understanding of the lived experience of children who …

Factors Influencing The Incidence Rates Of Injuries And Accidents Among Seafarers And Rig Workers Providing Support To The Wa Offshore Oil And Gas Industry, Tony Martinovich

Theses: Doctorates and Masters

The aim of this study was to identify, discuss and make recommendations regarding causal factors associated with injuries and accidents among seafarers and rig workers providing support to the WA offshore oil and gas industry. These incidents cause significant personal and economic burdens for employees, employers and the community in general.

A sample of 484 participants were recruited from a workforce of 9800 employees (approximately 5%). Participants were stratified into 2 cohorts; those who had suffered injury (286 – study group) and those who had not (198 - controls).

Data from the study group were stratified into oilrig workers and …

An Analysis Of Treatment Retention And Attrition In An Australian Therapeutic Community For Substance Abuse Treatment, Mark Robert Porter

Theses: Doctorates and Masters

Research undertaken in the last three decades has consistently reported that the length of time spent in inpatient and outpatient alcohol and other drug (AOD) treatment programs predicts treatment success (De Leon, Melnick, Kressel, & Jainchill, 1994; Hubbard, Craddock, & Anderson, 2003; Simpson, Joe, Fletcher, Hubbard, & Anglin, 1999). However, treatment attrition rates are high and present a major problem for improving treatment outcomes. Various factors that have been reportedly associated with increased AOD treatment attrition rates include being female, younger clients, clients using methamphetamines, and clients with elevated psychopathology scores. The aim of this thesis is to improve understanding …

Magnetocardiography In Unshielded Environment Based On Optical Magnetometry And Adaptive Noise Cancellation, Valentina Tiporlini

Theses: Doctorates and Masters

This thesis proposes and demonstrates the concept of a magnetocardiographic system employing an array of optically-pumped quantum magnetometers and an adaptive noise cancellation for heart magnetic field measurement within a magnetically-unshielded environment.

Optically-pumped quantum magnetometers are based on the use of the atomic-spin-dependent optical properties of an atomic medium. An Mxconfiguration- based optically-pumped quantum magnetometer employing two sensing cells containing caesium vapour is theoretically described and experimentally developed, and the dependence of its sensitivity and frequency bandwidth upon the light power and the alkali vapour temperature is experimentally demonstrated. Furthermore, the capability of the developed magnetometer of measuring very weak …

The Development And Evaluation Of A Testing Protocol To Assess Upper Body Pressing Strength Qualities In High Performance Athletes, Kieran Young

Theses: Doctorates and Masters

PURPOSE: The purpose of this study was to evaluate the reliability of an isometric force assessment (isometric bench press) across 4 standardised angles and an isoinertial force and velocity assessment (ballistic bench throw) utilising a relative load based on a percentage of one repetition maximum (1RM) in the bench press; and to evaluate whether the use of the dynamic strength deficit (DSD) ratio can guide training and detect changes induced by training over a 5 week period.

METHODS: Twenty four elite male athletes (age = 19.9 ± 2.7yrs; mass = 79.1 ± 13.0kg) performed the isometric bench press and a …

Characterising The Deformation Behaviour Of Human Tooth Enamel At The Microscale, Simona O'Brien

Theses: Doctorates and Masters

Enamel plays an important role in tooth function. Optimal combinations of composition and structure endow enamel with unique mechanical properties that remain largely unexplored. Specifically, more detailed understanding of the loadbearing ability of enamel is needed to mimic it synthetically and to design next generation biocomposite materials. This research investigates the variables that influence deformation behaviour of tooth enamel in relation to its hierarchical structure. Initially, a new method was developed for preparing flat, finely polished tooth samples that were maintained in their normal hydrated state for nanoindentation testing. In contrast to conventional methods, which commonly utilise either inappropriate or …

Discovery Of New Biomarkers Of Mild Cognitive Impairment And Alzheimer's Disease Risk In Buccal Cells Using Laser Scanning Cytometry, Maxime Francois

Theses: Doctorates and Masters

Previous studies have shown that mild cognitive impairment (MCI) may reflect the early stages of more pronounced neurodegenerative disorders such as Alzheimer’s disease (AD). In clinical practice, patients with AD are not usually identified until the disease has progressed to a stage when primary prevention is no longer possible. Therefore there is a need for a minimally invasive and inexpensive diagnostic to identify those who exhibit cellular pathology indicative of MCI and AD risk so that they can be prioritised for primary prevention. Human buccal cells are accessible in a minimally invasive manner, and exhibit cytological and nuclear morphologies that …

Framing Anorexia : A Play Script And Multidimensional Investigation Of Anorexia : A Play And Critical Essay, Louise Helfgott

Theses: Doctorates and Masters

This thesis explores anorexia nervosa in young people. It comprises two components: a play script, "Frames", about 16-year-old Elizabeth who is combating the disorder, her troubled friend Ben, and their families, and a critical essay that reviews qualitative and quantitative literature about anorexia and contextualises the play in relation to selected narratives, plays and films. In my field research, I interviewed a number of professionals working in the field of anorexia and the essay also discusses their views and insights.

Few plays deal with anorexia in an in-depth manner to explore the onset and development of the illness. "Frames" addresses …

Exploring Predictors Of Sport Commitment In Coaches, Erin Bormann

Theses: Doctorates and Masters

The Sport Commitment Model (SCM) has been used to gain insight about the factors that influence people’s decision to continue participation in sport. Majority of the studies that are grounded in the SCM have been conducted with athletes. To date, few studies have examined sport commitment of coaches however, these did not assess two commitment dimensions per se (functional or “want to” and obligatory or “have to” commitment to sport), rather each has measured certain predictor variables and inferred commitment dimensions based on clustering of predictors [i.e. 13]. This study had one main purpose, to examine the SCM amongst coaches. …

Improving Evaluations Of Anti-Bullying Programs In Schools, Thérèse Shaw

Theses: Doctorates and Masters

Bullying at school is associated with negative social, psychological and academic outcomes for both the victimised student and the perpetrator. As a consequence, national strategies to address bullying have been implemented in numerous countries, and education sectors and schools have increasingly directed resources to the problem. To ensure resources are allocated to programs and strategies that will prevent and successfully respond to bullying in schools, and therefore prevent harm to students, evidence of program effectiveness is required. Evaluations of anti-bullying programs in schools have had mixed results and there is a lack of robust evidence as to their impact. Several …

Neuromuscular Fatigue And Biomechanical Alterations During High-Intensity, Constant-Load Cycling, Amanda Julie Overton

Theses: Doctorates and Masters

Neuromuscular fatigue is an inevitable process at play during prolonged exercise, and may be caused by multiple alterations within the central nervous system and peripheral musculature. As fatigue develops, the neuromuscular system must adapt to these changes by making compensatory movement pattern adjustments so as to use motor pathways that are less fatigued in an effort to maintain task performance; motor variability is thus increased. The primary purpose of the four studies contained within this doctoral thesis was to detail the progression of exercise-induced neuromuscular fatigue, and to improve our understanding of the muscle activation and joint kinematic alterations that …

The Governance Schema Of Regional And Rural Public Hospital Nurses: How Relevant Are The Dimensions Of Stewardship Governance And Trust In Management?, Kim Clark

Theses: Doctorates and Masters

This study broadly pertained to the issue of public health sector governance. The field of healthcare governance had been characterised as having challenges of greater intricacy and sensitivity than those found in any other sector (Philippon & Braithwaite, 2008). While increasingly regarded as important to health system performance, governance had, however, been evaluated as poorly understood in conceptual and practical terms and subject to competing ideas regarding its role and challenges (Brinkerhoff & Bossert, 2013). Specifically, the thesis elucidated frontline regional and rural hospital nurses’ cognitive schema of strategic aspects of governance practice of managers in the Western Australian Country …

The Identification Of Diagnostic Serological Autoantibodies For Cutaneous Melanoma, Pauline Zaenker

Theses: Doctorates and Masters

Abstract not available.

A Model Of Management Learning For Occupational Therapists In Small Business In Australia, Jeannine Millsteed

Theses: Doctorates and Masters

This research sought to identify factors that contribute to occupational therapists developing management competencies when they become small business owners providing professional clinical services. This is an important for several reasons and precipitated by the Australian government’s introduction of incentives that encourage health professions to move from employment in public hospitals into the private sector, coupled with a recognition that occupational therapists receive no formal business training in their professional education, and the reported high levels of business failure in the small business sector. A review of the literature established the value of small business to the Australian economy, growth …

Biomarkers Of Disease : Concentrations In The Serum Of Women During Natural And Stimulated Ovarian Cycles And During Early Pregnancy, Melissa Stemp

Theses: Doctorates and Masters

Molecular biomarkers are chemical signatures that all cell types possess. They are used in medicine to evaluate both normal biological events and pathogenic processes. A series of biomarkers associated with cancer of the breast, ovaries and other parts of the female reproductive tract and the monitoring of pregnancy were measured in disease‐free women. The biomarkers measured were prostate specific antigen (PSA), CA125, CA15‐3, CA72‐4, and pregnancy associated plasma protein‐a (PAPP‐A). The patterns of change during natural and stimulated ovarian cycles and early pregnancy were investigated to determine if these biomarkers could reflect normal events relating to ovulation and implantation/placentation. In …

Pax3 Expression, Protein Modifications And Downstream Target Gene Profiling In Melanocytes And Melanoma Cells, Danielle Bartlett

Theses: Doctorates and Masters

PAX3 is a transcription factor. It plays a major role in the development of melanocytes in the embryo. As a result of alternative splicing, the gene gives rise to eight different transcripts which encode proteins that have differing structures and are therefore likely to activate different downstream target genes. The presence of post-translational modifications has also been shown to alter the functions of the proteins.

PAX3 regulates the maintenance of undifferentiated melanoblasts and mediates pathways involved in proliferation, migration and survival. It has been shown to be expressed in melanoblasts, adult melanocytes, naevi and in most melanoma cells. This implies …

Approach-Iron Play In High Performance Golf: From Testing To Tournament Play, Samuel John Robertson

Theses: Doctorates and Masters

The capability of a golfer to record a low score depends upon well-developed abilities in each of the recognised on-course skill components (driving the ball off the tee, hitting approach-iron shots, hitting short-iron shots and putting). Despite approach-iron play being considered perhaps the most important and definitely the most practiced skill in the game, the ability to quantify the golfer’s ability to hit approach-iron shots in a controlled, off-course environment (eg. training) cannot yet be undertaken due to the lack of appropriate assessments. Such tools have considerable potential for use in both the field and in research for implementation in …

Exercise As Medicine : Reversing Treatment Toxicities In Prostate Cancer Patients, Bradley A. Wall

Theses: Doctorates and Masters

A common treatment for prostate cancer, which is the most common form of cancer after skin cancer in Australian males, is androgen deprivation therapy (ADT). However, ADT is associated with an array of adverse effects including reduced bone and lean mass, loss of muscle strength, negative change in lipid profile, and increased risk of cardiovascular disease (CVD) as well as diabetes, all of which can compromise physical function and quality of life. Physical exercise has been suggested as a key lifestyle intervention for this group of cancer patients as it has enormous potential to limit and even reverse the effects …

Migration Matters : The Experience Of United Kingdom Registered Nurses Migrating To Western Australia, Caroline J. Vafeas

Theses: Doctorates and Masters

This qualitative study uses heuristic inquiry to investigate the unique journey of 21 registered nurses (RN) who migrated from the United Kingdom (UK) to Perth in Western Australia (WA) between 2003 and 2008. The study explores the reasons for migration as well as the professional, social and psychological impact on each participant and their accompanying family during the first two years of settling in a new country.

In the contemporary climate of international nurse mobility, many employers are attempting to attract new employees, often with tantalising offers of an immediate visa and the enticement of a better climate and standard …
