Assessment Of Joint Kinetics In Elite Sprint Cyclists, Lynne Munro

Theses: Doctorates and Masters

Sprint cycling requires the production of explosive muscle power outputs up to very high pedalling rates. The ability to assess muscular function through the course of the sprint would aid training practices for high-level performers. Inverse dynamics provides a non-invasive means of estimating the net muscle actions acting across any joint contributing to movement. However, analysis of joint kinetics requires motion-capture techniques that present some unique challenges for cycling. This thesis presents three studies investigating the application of a custom-designed force pedal system to examine the joint kinetics of elite trained track sprint cyclists. To provide the basis for selecting …

The Utility Of Multidisciplinary Rehabilitation As A Treatment Strategy For Circadian Rhythm And Sleep Disturbances In Premanifest Huntington’S Disease, Danielle Megan Bartlett

Theses: Doctorates and Masters

Background: Huntington’s disease (HD) is a rare, neurodegenerative disease caused by an expanded cytosine-adenine-guanine (CAG) sequence in the Huntingtin gene, resulting in the production of an aberrant protein, mutant huntingtin (mHTT). The mHTT protein exhibits a toxic loss and gain in function, leading to degeneration of neurons in the brain. Consequently, the classic triad of motor, cognitive and mood features of the disease develop. Among the earliest features of HD are circadian rhythm and sleep disturbances. These anomalies present many years prior to formal clinical diagnosis of HD and, while it has been postulated that these disturbances arise as a …

Lifestyle Health Behaviors Of Nurses And Midwives: The ‘Fit For The Future’ Study, Lin Perry, Xiaoyue Xu, Robyn Callagher, Rachel Nicholls, David Sibbritt, Christine Duffield

Research outputs 2014 to 2021

Nurses and midwives (nurses) are the principle role models and health educators for the wider population. This study sought to identify the health-related behaviors of the nursing workforce of New South Wales (NSW), Australia, compared to contemporary recommendations for healthy living and to the Australian general population, matched by gender and age. An electronic cross-sectional survey delivered in 2014–2015 recruited 5041 nurses through the NSW Nurses and Midwives Association and professional networks. Validated health behavior measures were collected and compared to Australian National Health Survey data. Compared with younger nurses, older nurses reported greater adherence to fruit and vegetable guideline …

Glucose Gel As A Potential Alternative Treatment To Infant Formula For Neonatal Hypoglycaemia In Australia, Raenee L. Barbe, Amy K. Ekin, Pushparani Sivakumar, Kay Howard, Therese O'Sullivan

Research outputs 2014 to 2021

Infant formula is often used as a treatment for neonatal hypoglycaemia in Australia; however, there are concerns that this may jeopardise mother-baby bonding and breastfeeding. Successful use of glucose gel as an alternative treatment for hypoglycaemia has been reported. We wanted to investigate in a pilot study whether the use of glucose gel has the potential to quickly and safely restore normoglycaemia in the infants of diabetic mothers in an Australian setting. Infants with asymptomatic hypoglycaemia were treated with glucose gel (n = 36) and compared to a historical group of infants which had been treated with infant formula …

The Psychometric Assessment Of Alexithymia: Development And Validation Of The Perth Alexithymia Questionnaire, David Preece, Rodrigo Becerra, Ken Robinson, Justine Dandy, Alfred Allan

Research outputs 2014 to 2021

Alexithymia is a trait comprising people's ability to focus attention on and accurately appraise their own emotions. Its assessment is of clinical interest because people who have difficulty processing their negative and positive emotions are more vulnerable to developing psychopathology symptoms, however, existing alexithymia measures cannot comprehensively assess the construct across both negative and positive emotions. In this paper, we attempt to remedy these measurement limitations by developing and validating a new 24-item self-report measure, the Perth Alexithymia Questionnaire (PAQ), which is based on the attention-appraisal model of alexithymia. In Study 1, our confirmatory factor analyses in a sample of …

I Understand You Feel That Way, But I Feel This Way: The Benefits Of I-Language And Communicating Perspective During Conflict, Shane L. Rogers, Jill Howieson, Casey Neame

Research outputs 2014 to 2021

Using hypothetical scenarios, we provided participants with potential opening statements to a conflict discussion that varied on I/you language and communicated perspective. Participants rated the likelihood that the recipient of the statement would react in a defensive manner. Using I-language and communicating perspective were both found to reduce perceptions of hostility. Statements that communicated both self- and other-perspective using I-language (e.g. ‘I understand why you might feel that way, but I feel this way, so I think the situation is unfair’) were rated as the best strategy to open a conflict discussion. Simple acts of initial language use can …

An Ehealth Program For Patients Undergoing A Total Hip Arthroplasty: Protocol For A Randomized Controlled Trial, Rosemary Saunders, Karla Seaman, Catherine Ashford, Trudy Sullivan, Judith Mcdowall, Lisa Whitehead, Bev Ewens, Kathryn Pedler, Karen Gullick

Research outputs 2014 to 2021

Background: Total hip arthroplasty is an effective surgical procedure commonly used worldwide for patients suffering the disabling effects of osteoarthritis when medical therapy is unsuccessful. Traditionally pre- and postoperative information for patients undergoing a hip arthroplasty has been provided by paper-based methods. Electronic health (eHealth) programs to support individualized patient education on preoperative preparation, in-patient care, and home rehabilitation have the potential to increase patient engagement, enhance patient recovery, and reduce potential postoperative complications.

Objective: The aim of this study is to compare the addition of an eHealth program versus standard care for pre- and postoperative education on patient outcomes …

Challenges And Strategies For Assessing Student Workplace Performance During Work-Integrated Learning, Denise Jackson

Research outputs 2014 to 2021

This study explores the challenges of assessing student workplace performance during work-integrated learning. It highlights the need for, yet difficulties with, combining positivist and constructivist assessments where workplace supervisors make evaluative judgements on performance yet students are also agents in their own assessment. It examines the ratings awarded by 163 workplace supervisors for 213 business undergraduates completing a work placement as part of their degree program in Western Australia. Students were rated on 17 capabilities associated with employability and results indicate, in alignment with previous studies, a tendency among supervisors to assign inflated marks across capabilities. The mean capability rating …

Cynicism About Change, Work Engagement, And Job Satisfaction Of Public Sector Nurses, Diep T. N. Nguyen, Stephen T. Teo, David Pick

Research outputs 2014 to 2021

This paper uses the job demands‐resources theory to examine the consequences of changes on nursing work. Data were collected from 220 public sector nurses in Australia to test the model. We conducted a two‐wave data collection process where independent variables (organisational change, workload, job control, nursing administrative stressors, cynicism about organisational change, and demographic variables) were collected in Time 1. The dependent variables (nursing work engagement and job satisfaction) were collected 6 months later. Changes to nursing work were found to cause high workload and an increase of administrative stressors that leads to an increase in nurses’ change cynicism. Job …

The Image Of India As A Travel Destination And The Attitude Of Viewers Towards Indian Tv Dramas, Usep Suhud, Gregory B. Willson

Research outputs 2014 to 2021

For a few decades now, various television stations in Indonesia have been broadcasting foreign drama series including those from a range of Asian countries, such Korea, India, Turkey, Thailand and the Philippines . This study aims to explore attitude towards Asian drama in those countries and the destination image of the country where the drama emanates from as perceived by the audiences. This study applied a mixed-methodology approach in order to explore particularly attitudes towards foreign television drama productions. There is a paucity of study exploring the attitudes of audiences towards Indian television dramas and a limited study focussing on …

An Explanation Of Apology Acceptance Based On Lay Peoples’ Insights, James Strickland, Katie Martin, Alfred Allan, Maria M. Allan

Research outputs 2014 to 2021

Apologies play an important role in forgiveness, but the pathway from apology to forgiveness is unclear. Many researchers use Goffman’s model of the corrective interchange, or models derived from it to guide their research. This model is based on the assumption that offenders apologise to victims who accept these apologies and that this leads to forgiveness. The acceptance of the apology is therefore central in this model, so we undertook a systematic literature review to determine how researchers conceptualise and measure apology acceptance and found a lack of clarity around the construct. We addressed this theoretical uncertainty by exploring whether …

Biometrics Based Privacy-Preserving Authentication And Mobile Template Protection, Wencheng Yang, Jiankun Hu, Song Wang, Qianhong Wu

Research outputs 2014 to 2021

Smart mobile devices are playing a more and more important role in our daily life. Cancelable biometrics is a promising mechanism to provide authentication to mobile devices and protect biometric templates by applying a noninvertible transformation to raw biometric data. However, the negative effect of nonlinear distortion will usually degrade the matching performance significantly, which is a nontrivial factor when designing a cancelable template. Moreover, the attacks via record multiplicity (ARM) present a threat to the existing cancelable biometrics, which is still a challenging open issue. To address these problems, in this paper, we propose a new cancelable fingerprint template …

Conspicuously Concealed: Revision Of The Arid Clade Of The Gehyra Variegata (Gekkonidae) Group In Western Australia Using An Integrative Molecular And Morphological Approach, With The Description Of Five Cryptic Species, Luke Kealley, Paul Doughty, Mitzy Pepper, J. Scott Keogh, Mia Hillyer, Joel Huey

Research outputs 2014 to 2021

The methods used to detect and describe morphologically cryptic species have advanced in recent years, owing to the integrative nature of molecular and morphological techniques required to elucidate them. Here we integrate recent phylogenomic work that sequenced many genes but few individuals, with new data from mtDNA and morphology from hundreds of gecko specimens of the Gehyra variegata group from the Australian arid zone. To better understand morphological and geographical boundaries among cryptic forms, we generated new sequences from 656 Gehyra individuals, largely assigned to G. variegata group members over a wide area in Western Australia, with especially dense sampling …

Children’S Perceptions Of The Importance And Value Of Reading, Margaret K. Merga, Saiyidi Mat Roni

Research outputs 2014 to 2021

Fostering children’s engagement in regular recreational reading beyond independent skill acquisition is beneficial to promote continued literacy engagement. Regular recreational reading is associated with both literacy skill acquisition and maintenance across the life span. Children’s perceptions of the importance and value of reading can influence their motivation to read. However, it is not currently known if children continue to perceive the value of reading beyond the period of independent reading skill acquisition. Findings from a sample of 997 older elementary children indicate that some children may not recognise the value of reading beyond independent reading skill acquisition. This is particularly …

A ‘Better’ Education: An Examination Of The Utility Of Boarding School For Indigenous Secondary Students In Western Australia, Mary-Anne Macdonald, Eyal Gringart, Terry Ngarritjan Kessaris, Martin Cooper, Jan Gray

Research outputs 2014 to 2021

Over the past 10 years, great improvements have been observed in the Year 12 attainment rate of Indigenous Australians. This has been due, in part, to government funding of programmes aimed at improving education opportunity for Indigenous Australian students, including funding of scholarships for students from remote areas to attend boarding schools. The current qualitative study investigated the perspectives of school leaders and Indigenous secondary students across the Australian state of Western Australia, on the utility and impact of this boarding provision. Students identified that boarding education allowed them to achieve a dual goal of meaningful career pathways and improved …

An Entropy-Histogram Approach For Image Similarity And Face Recognition, Mohammed Aljanabi, Zahir Hussain, Song F. Lu

Research outputs 2014 to 2021

Image similarity and image recognition are modern and rapidly growing technologies because of their wide use in the field of digital image processing. It is possible to recognize the face image of a specific person by finding the similarity between the images of the same person face and this is what we will address in detail in this paper. In this paper, we designed two new measures for image similarity and image recognition simultaneously. The proposed measures are based mainly on a combination of information theory and joint histogram. Information theory has a high capability to predict the relationship between …

Development Of An Australian Nursing Critical Thinking Tool Using A Delphi Process, Elisabeth R. Jacob, Christine M. Duffield, Darren Jacob

Research outputs 2014 to 2021

Aim: To develop a critical thinking assessment tool for Australian undergraduate nurses. Background: Critical thinking is an important skill but difficult to assess in nursing practice. There are often many responses a nurse can make to a clinical problem or situation. Some responses are more correct than others and these decisions have an impact on a patient's care and safety. Differences in a response can relate to the depth of knowledge, experience and critical thinking ability of the individual nurse. Design: This study used a Delphi process to develop five clinical case studies together with the most appropriate clinical responses …

Entrepreneurial Csr, Managerial Role And Firm Resources: A Case Study Approach, Alonso Duarte, Ian P. Austin

Purpose: The purpose of this study is to contribute to the extant body of the entrepreneurship and business management literature, investigating corporate social responsibility (CSR) and its implications for firms’ competitiveness. The cases of four different firms are examined through the lens of the resource-based view of the firm and role theory. Design/methodology/approach: Face-to-face and telephone interviews were conducted with the owners and managers of four model firms identified in Western Australia. Findings: While financial outcomes clearly stand out as the end goal for engaging in CSR-related practices, the importance of firm managers’ entrepreneurial role emerges in using existing resources …

An Investigation Of Mobile Phone Use While Driving: An Application Of The Theory Of Planned Behavior, Sokunthea Kruy

Theses: Doctorates and Masters

Mobile phone use while driving has been an emerging issue for road safety in recent years. The development of new technology has meant that users are more connected to their devices than ever before. This has led to use while driving despite the illegality of this behaviour. In this research, three mobile phone use behaviours were investigated: making/receiving calls; creating/sending text messages, and accessing social media. Through application of the Theory of Planned Behavior (TPB), an online survey was developed. Five hundred and fifty-nine university students including 193 young respondents (aged 17 – 25) responded to investigate attitudes, subjective norms, …

Seed Morphology, Dormancy And Germination Of South-West Australian Ericaceae, Michael Just

Theses: Doctorates and Masters

The Ericaceae in South West Australia contains species with difficult to germinate seeds, including many species with deep intractable dormancy. A better understanding of seed biology and species specific dormancy, and germination mechanisms is required to overcome these difficulties. Land clearing, salinity and disease has resulted in over 125 species within 15 genera being listed as rare, highly restricted, threatened and endangered (Western Australian Herbarium 1998–). The present study examined the seed biology of eight species of Ericaceae native to Western Australia, exploring fruit and seed morphology, dormancy and germination. Cold and warm stratification was used in combination with gibberellic …

The Mechanics Of Front Leg Loading During Cricket Fast Bowling: Delivery Variations, Spell Demands, And The Effects Of Strength Training, Samuel J. Callaghan

Theses: Doctorates and Masters

The goal of fast bowling in cricket is to dismiss a batsman for as few runs as possible. To assist this goal, fast bowlers will attempt to maximise ball release velocity (BRV) to decrease the decision-making and stroke execution time of the opposing batsmen. Fast bowlers will also employ various delivery lengths (i.e. short, good and full) to assist in affecting a batsman’s stroke execution.

Several issues remain to be addressed with regards to the biomechanical assessment of fast bowling. This is particularly evident when analysing fast bowling performance (i.e. BRV), the implications of front foot loading (i.e. vertical and …

Neuromuscular Factors Contributing To Reductions In Muscle Force After Repeated, High-Intensity Muscular Efforts, Benjamin J. C. Kirk

Theses: Doctorates and Masters

Fatigue can accumulate sufficiently to limit muscular force production during repeated, forceful muscle contractions, including those that occur in the occupational, clinical and athletic settings. Fatigue during such efforts is likely to result from disturbances to multiple processes in the nervous system and muscle. However, previous research examining the mechanisms underpinning fatigue have typically required subjects to perform low-level constant-force contractions or to repeat maximal efforts in a single set format. Such tasks do not translate well to occupational, daily living or athletic situations where high-intensity, yet submaximal, repeated efforts may be performed in work bouts (or sets) with brief …

Within-Fire Patchiness Associated With Prescribed Burning In The Northern Jarrah Forests Of Western Australia, Zigourney Nielsen

Theses: Doctorates and Masters

There is growing understanding of the importance of landscape mosaics and heterogeneity for biodiversity outcomes in Western Australia. However, there is limited information on the patchiness (spatial configuration of unburnt and burnt patches which occur at a range of spatial scales) within the perimeter of a single prescribed burn. Of particular concern is the idea that prescribed burning operations, carried out under very restricted weather and environmental conditions, can lead to structural and floristic homogenization of the area within a burn perimeter. This may be evident as reduced post-fire vegetation patchiness. Western Australian Jarrah (Eucalyptus marginata) forests are managed to …

Holistic Health: Shaping Women’S Experiences Of Positive Body Image, Helen Elizabeth Monks

Theses: Doctorates and Masters

This PhD thesis seeks to contribute to a nuanced understanding of positive body image and how it is expressed among a group of women participating in holistic health culture in a modern Western society. Qualitative data were collected from in-depth ethnographic interviews with 25 women in Perth, Western Australia, to illuminate an understanding of their holistic health beliefs and practices, perceptions of appearance and health ideals, as well as their understandings of positive body image. Thematic analysis of the data through Nvivo revealed several overarching themes, demonstrating how certain aspects of holistic health culture may encourage or dissuade the development …

Ghanaian Parents’ Experiences Of Caring For Their Preterm Infants After Discharge From The Neonatal Unit - A Narrative Inquiry Study, Esther Abena Adama

Theses: Doctorates and Masters

The care of preterm infants is associated with stress. In the busy neonatal unit where highly skilled healthcare workers are always present, parents have reported being stressed when caring for their preterm infants in the neonatal unit. In Ghana, preterm birth is the highest cause of neonatal mortality with 70% of these morbidities and mortalities occurring in the community. Yet to date, no study in Ghana has explored how parents experience their care giving role after discharge from the neonatal unit into the community.

This study explored the experiences of caring for preterm infants in the neonatal unit and after …

Teacher Identity Construction In A Tesol Graduate Certificate Of Education In Western Australia, Arman Abednia

Theses: Doctorates and Masters

This research project explored the potential of a second language teacher education course for fostering teacher identity negotiation. It was found that classroom conversations provided a rich space for teacher identity negotiation; however, no substantial changes were observed in most aspects of their identities during the course, except for a growth in a few teachers’ selfconfidence. The implications are that conducting teacher education in an interactive manner is highly beneficial, but deeper engagement with practice of teaching is recommended. These insights should facilitate positive outcomes for teacher education programs.

A Framework For Development Of Android Mobile Electronic Prescription Transfer Applications In Compliance With Security Requirements Mandated By The Australian Healthcare Industry, Kyaw Kyaw Htat

Theses: Doctorates and Masters

This thesis investigates mobile electronic transfer of prescription (ETP) in compliance with the security requirements mandated by the Australian healthcare industry and proposes a framework for the development of an Android mobile electronic prescription transfer application. Furthermore, and based upon the findings and knowledge from constructing this framework, another framework is also derived for assessing Android mobile ETP applications for their security compliance.

The centralised exchange model-based ETP solution currently used in the Australian healthcare industry is an expensive solution for on-going use. With challenges such as an aging population and the rising burden of chronic disease, the cost of …

The Influence Of A Simulated Olympic Distance Cycle Exercise On Subsequent Running Economy And Biomechanics In Triathletes, Chantelle Du Plessis

Theses: Doctorates and Masters

The multidisciplinary sport of triathlon provides a good model for testing whether a secondary task can be negatively affected by a preceding task, especially when movement patterns are different. Research suggests that cycling exercise impairs subsequent running performance by altering a runner’s economy and various mechanics (or technique-related) parameters. However, this is not an unambiguous finding. Furthermore, movement patterns are self-optimised during cycling and running to minimise the energy cost, yet the relationship between running mechanics and economy are not clear when different locomotor tasks are performed in succession

Two research studies were conducted with the focus of describing and …

Genetic Determinants Of Rates Of Cognitive Decline In Preclinical Alzheimer’S Disease, Tenielle L. S. Porter

Theses: Doctorates and Masters

In 2015 the number of people worldwide living with Dementia was 46.8 million, with approximately 50-75% of these cases being clinically defined as Alzheimer’s disease (AD). Despite extensive efforts, clinical trials have so far failed to yield a treatment that successfully addresses the underlying cause of AD. This lack of treatment has been suggested, in part, to be a result of late stage of intervention in current clinical trial design. For this reason, greater focus has been placed on preclinical trials and in turn both the identification of individuals at-risk for AD and, amongst these, those that are expected to …

The Beloved: A Documentary Film On The History And Aftermath Of Fremantle’S Rajneesh Sannyasin Community – And – Hidden Realities: Transcendental Structures In Documentary Film: An Exegesis, Joseph London

Theses: Doctorates and Masters

This creative work and its associated exegesis examines the concept of what I have termed a ‘transcendental structure’ in relation to a documentary film form, and what outcomes, specific to a non-fiction mode of representation, result from the application of this structure. A transcendental structure in film has a long history of investigation and interpretation in narrative fiction film theory and practice, but is substantially absent from documentary scholarship. The topic appears, in different forms, in the critical writings of Zavattini (1940), Bazin (1946), Pasolini (1965), Schrader (1972), Deleuze (1985), and more recently, Perez (1998) and Minghelli (2016). All of …
