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 …

Research outputs 2014 to 2021

Introduction Leg order during sequential single-leg cycling (i.e., exercising both legs independently within a single session) may affect local muscular responses potentially influencing adaptations. This study examined the cardiovascular and skeletal muscle hemodynamic responses during double-leg and sequential single-leg cycling. Methods Ten young healthy adults (28 ± 6 yr) completed six 1-min double-leg intervals interspersed with 1 min of passive recovery and, on a separate occasion, 12 (six with one leg followed by six with the other leg) 1-min single-leg intervals interspersed with 1 min of passive recovery. Oxygen consumption, heart rate, blood pressure, muscle oxygenation, muscle blood volume, and …

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 …

Research outputs 2014 to 2021

The PhysioFlow bioimpedance cardiography device provides key measures of central systolic and diastolic and peripheral vascular function. Many of these variables have not been assessed for intrarater reliability and agreement during rest, submaximal exercise and high-intensity interval exercise. Twenty healthy adults (age: 26±4 years) completed two identical trials beginning with five minutes of rest followed by two 5-minute submaximal cycling bouts at 50% and 70% of peak power output. Subjects then completed ten 30-second cycling intervals at 90% of peak power output interspersed with 60 s of passive recovery. Bioimpedance cardiography (PhysioFlow; Manatec Biomedical, France) monitored heart rate, stroke volume, …

Relationship Between Strength And Power Production Capacities In Trained Sprint Track Cyclists, James Vercoe, Mike R. Mcguigan

Research outputs 2014 to 2021

Ten participants including six women and four men (age: 22.1±6.8 years, body height: 176.1±6.7 cm, body weight: 72.1±7.9 kg) performed isometric mid-thigh pull (IMTP) and isokinetic sprint tests. Variables measured included peak force (PF), peak rate of force development (PRFD) for the IMTP and maximal torque and maximal power (Pmax) for the isokinetic sprint test. There was a strong relationship between PF on the IMTP and maximal peak torque values across five isokinetic sprints (r=.890-.925). Strong relationships were also shown …

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 …

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 …

Measuring Emotion Regulation Ability Across Negative And Positive Emotions: The Perth Emotion Regulation Competency Inventory (Perci), David Preece, Rodrigo Becerra, Ken Robinson, Justine K. Dandy, Alfred Allan

Research outputs 2014 to 2021

Emotion regulation problems underlie the abnormal levels of negative or positive emotion that characterise many forms of psychopathology. Several self-report measures of emotion regulation ability exist, but many are inconsistent with contemporary emotion regulation theory, and none comprehensively assess this construct across both negative and positive emotions. In this paper, we report our attempt to remedy these measurement limitations by developing and validating the Perth Emotion Regulation Competency Inventory (PERCI), a 32 item self-report questionnaire that measures emotion regulation ability as it is defined by the extended process model of emotion regulation. In Study 1, our confirmatory factor …

Research outputs 2014 to 2021

The aim of this study was to investigate the impact of aerial manoeuvres on scoring in professional surfing. 23,631 waves were analysed for the number and types of aerial manoeuvres performed from the 2014, 2015 and 2016 Men’s World Championship Tour. Additionally, the awarded score, timing and order of the aerial was also analysed. Descriptive statistics and Two Way ANOVA’s were performed with Sidak Multiple Comparisons Post Hoc analysis. Results were a significantly higher score being awarded (P ≤ 0.0001) when including an aerial in competition across all three seasons. In 2015 surfers were awarded a significantly larger score …

Social Impacts Of Occupational Heat Stress And Adaptation Strategies Of Workers: A Narrative Synthesis Of The Literature, Victor Fannam Nunfam, Kwadwo Adusei-Asante, Eddie John Van Etten, Jacques Oosthuizen, Kwasi Frimpong

Research outputs 2014 to 2021

Dimensions of risks and impacts of occupational heat stress due to climate change on workers' health and safety, productivity, and social well-being are significantly deleterious. Aside from empirical evidence, no systematic review exists for policy development and decision making in managing occupation heat stress impacts and adaptation strategies of workers. This study sought to synthesise evidence on the social impacts of occupational heat stress and adaptation strategies of workers. From a review of existing literature, eight categories were obtained from 25 studies and grouped into three syntheses: (1) awareness of occupational heat stress, (2) social impacts of occupational heat stress …

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 …

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

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, …

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 …

No-One Was Watching: A Collection Of Short Fiction And Stories Beyond The Gates: An Exegesis, Ann Elizabeth Horner

Theses: Doctorates and Masters

This research project asserts the primacy of creative practice as a key method of enquiry and explores how fictional stories, re-imagined from historical events of the mid-twentieth century, may provide different ways of viewing a world which was inhabited by once-silenced children, now known as the ‘forgotten Australians’. To this end, the thesis is made up of a creative component in the form of a book-length collection of short fiction that is accompanied by a critical component positioning the thesis contextually, theoretically and methodologically. The research reveals overwhelming evidence of a culture of endemic abuse within Australian child welfare organisations …

Time On Androgen Deprivation Therapy And Adaptations To Exercise: Secondary Analysis From A 12-Month Randomized Controlled Trial In Men With Prostate Cancer, Dennis R. Taaffe, Laurien M. Buffart, Robert U. Newton, Nigel Spry, James Denham, David Joseph, David Lamb, Suzanne K. Chambers, Daniel A. Galvao

Research outputs 2014 to 2021

Objectives

To explore if duration of previous exposure to androgen deprivation therapy (ADT) in men with prostate cancer (PCa) undertaking a year-long exercise programme moderates the exercise response with regard to body composition and muscle performance, and also to explore the moderator effects of baseline testosterone, time since ADT, and baseline value of the outcome.

Patients and Methods

In a multicentre randomized controlled trial, 100 men who had previously undergone either 6 months (short-term) or 18 months (long-term) of ADT in combination with radiotherapy, as part of the TROG 03.04 RADAR trial, were randomized to 6 months supervised exercise, followed …

Beyond Factor Analysis: Multidimensionality And The Parkinson’S Disease Sleep Scale-Revised, Maria E. Pushpanathan, Andrea M. Loftus, Natalie Gasson, Meghan G. Thomas, Caitlin F. Timms, Michelle Olaithe, Romola S. Bucks

Research outputs 2014 to 2021

Many studies have sought to describe the relationship between sleep disturbance and cognition in Parkinson’s disease (PD). The Parkinson’s Disease Sleep Scale (PDSS) and its variants (the Parkinson’s disease Sleep Scale-Revised; PDSS-R, and the Parkinson’s Disease Sleep Scale-2; PDSS-2) quantify a range of symptoms impacting sleep in only 15 items. However, data from these scales may be problematic as included items have considerable conceptual breadth, and there may be overlap in the constructs assessed. Multidimensional measurement models, accounting for the tendency for items to measure multiple constructs, may be useful more accurately to model variance than traditional confirmatory factor analysis. …

Developing A Unified Approach To Sustainable Consumption Behaviour: Opportunities For A New Environmental Paradigm, Vivienne Byers, Alan Gilmer

Articles

Politicians and national policy makers seek to encourage individuals to engage in a wide range of pro-environmental practices to address both discrete environmental problems and major global challenges such as climate change. Theoretically, the field of behavioural management in environmental consumption which seeks to change holarchic open human systems, is much contested. This paper proposes to develop a synthesized conceptual framework embracing a unified approach that addresses the systematic, structural, and institutional perspectives on how consumption, through public policy initiatives, can be developed and changed to reflect a deeper ecological foundation. This approach considers the debate regarding policy and behavioural …

The Link Between Spatial Skills And Engineering Problem-Solving, Gavin Duffy, Sheryl Sorby, Presentacion Rivera Reyes, Tom Delahunty, Lance Perez, Jayashri Ravishankar

Conference papers

Well-developed 3-D spatial skills are correlated with engineering success. However, most studies examining the link between spatial skills and engineering success have been conducted at the macro level, i.e., the link between spatial skills and course grades or between spatial skills and graduation rates. In this research, a more refined approach has been taken. Relationships between spatial skills and success in solving certain types of problems that engineering students commonly encounter are examined. It was found that high levels of spatial skills predict success in solving certain types of engineering problems but not in all types of problems. Data gathered …

Smokers And Ex-Smokers Have Shared Differences In The Neural Substrates For Potential Monetary Gains And Losses, Liam Nestor, Ella Mccabe, Jennifer Jones, Luke Clancy, Hugh Garavan

Articles

Despite an increased understanding of nicotine addiction, there is a scarcity of research comparing the neural correlates of non-drug reward between smokers and ex-smokers. Long-term changes in reward-related brain functioning for non-drug incentives may elucidate patterns of functioning that potentially contribute to ongoing smoking behaviour in current smokers. Similarly, examining the effects of previous chronic nicotine exposure during a period of extended abstinence may reveal whether there are neural correlates responsible for non-drug reward processing that are different from current smokers.

Quantitative Fine-Grained Human Evaluation Of Machine Translation Systems: A Case Study On English To Croatian, Filip Klubicka, Antonio Toral, Victor Manuel Sanchez-Cartagena

Articles

This paper presents a quantitative fine-grained manual evaluation approach to comparing the performance of different machine translation (MT) systems. We build upon the well-established Multidimensional Quality Metrics (MQM) error taxonomy and implement a novel method that assesses whether the differences in performance for MQM error types between different MT systems are statistically significant. We conduct a case study for English-to- Croatian, a language direction that involves translating into a morphologically rich language, for which we compare three MT systems belonging to different paradigms: pure phrase-based, factored phrase-based and neural. First, we design an MQM-compliant error taxonomy tailored to the relevant …
