Forensic Analysis Of A Crash-Damaged Cheerson Cx-20 Auto Pathfinder Drone, Ian Noel Mcateer, Peter Hannay, Muhammad Imran Malik, Zubair Baig

Research outputs 2014 to 2021

Long gone are the days when Unmanned Aerial Vehicles (UAVs) and drones (multirotor UAVs) were the exclusive domain of the military for surveillance or tactical strike purposes. For relatively little money mainly due to high-tech progression in microprocessor design, anyone can now purchase a drone with GNSS-tracking capabilities and can support a live high-resolution video feed to its flight controller. The global population of drones has sky- rocketed in recent years as this new technology has been embraced for both its recreational and commercial applications. However, the more nefarious members of society have also recognized the potential for using drones …

Assessing Alexithymia: Psychometric Properties And Factorial Invariance Of The 20-Item Toronto Alexithymia Scale In Nonclinical And Psychiatric Samples, David Preece, Rodrigo Becerra, Ken Robinson, Justine Dandy

Research outputs 2014 to 2021

The 20-item Toronto Alexithymia Scale (TAS-20) is a self-report questionnaire designed to measure the three components of alexithymia; difficulty identifying feelings in the self (DIF), difficulty describing feelings (DDF), and externally orientated thinking (EOT). We examined the scale’s psychometric properties in Australian nonclinical (N = 428) and psychiatric (N = 156) samples. In terms of factorial validity, confirmatory factor analyses found the traditional 3-factor correlated model (DIF, DDF, EOT) to be the best and most parsimonious solution, but it did not reach adequate levels of goodness-of-fit in either sample. Several EOT items loaded poorly on their intended factor, …

Understanding Writing Challenges Of Rural Msw Students: Preparing Students For Ethical Practice, Jennifer A. Shadik, Sarah B. Garlington, Terry Cluse-Tolar, Glenn Abraham

Contemporary Rural Social Work Journal

This study explores the attitudes and reflections of rural MSW students regarding writing. Twenty-seven students completed the modified Writing-to-learn Attitudes Survey (WTLAS). Fourteen completed an open-ended reflection where they were asked to assess their strengths and challenges in writing, as well as strategies for improvement. Results of WTLAS indicated students were anxious about writing, had difficulty organizing their thoughts, presenting their ideas clearly, and had little confidence in their writing. Results of the writing reflection indicated students were able to identify multiple challenges and strengths as well as means to remedy shortcomings. Qualitative analysis indicated the most frequent challenges were: …

Is Leadership The Key To Public Sector Retention In Regional Western Australia? An Exploratory Study, Damian Lambert

Theses: Doctorates and Masters

This research reviewed retention factors affecting the West Australian public sector (WAPS) in regional areas seeking to determine whether a leadership development program (LDP) could provide a strategic HRM solution. Using a mixed methods approach views of 9 leaders and 156 regional WAPS employees provided insights on retention issues and how a LDP might be designed and delivered to regional employees. Despite the attraction and retention factors impacting the WAPS, it was found that a LDP designed specifically for the regions can assist to attract talented staff and to a lesser extent improve retention in the regions.

Public Health Implications Of Metal Ash Concentrations From Prescribed Burns: A Study Of Open Jarrah Forests, John Edwards

Theses: Doctorates and Masters

Ash is not a homogenous product. It is the solid residue of combustion and contains a complex mixture of chemical products. The fire that produces ash is non-discriminatory in that it will burn anything that is combustible. The ash residue resulting from fires varies and is dependent on its source, and burn characteristics such as the temperature of the fire. Ash comprises particles of carbon, soot and trace elements. Ash presents public health risk to people and communities, through direct and indirect ingestion, inhalation and absorption. The health effects of ash exposure are not limited to symptoms affecting the eyes, …

The Photographic Other: Paradox In The Cathexis Of Longing, Alex Cilla Bradley

Theses: Doctorates and Masters

A photographic and written examination of paradox in relation to the photograph

This research aims to illuminate the relationship between paradox and photography, elaborated via Julia Kristeva’s notion of the abject. Paradox is considered in relation to photography in terms of repeated and unresolved debates about the status of the photograph as either an ‘index of reality’ (Bate, 2004, p. 1) or as a sign. The significance of this research lies in its re-motivation of abjection in terms of paradox, not in order to resolve such debates but, rather, to illuminate the importance of such unresolved contradictions in terms of …

Enhancing Learning And Assessment Of Pre-Service Teachers On Practicum Placements Using Mobile Technologies With Video Capture, Christopher E. Dann

Theses: Doctorates and Masters

Across all educational jurisdictions, each year, large numbers of pre-service teachers are assessed for their suitability for teaching during their teacher education courses, in schools and institutions through practicum placements or workplace learning. Despite their widespread use, practicums can be notoriously variable and unreliable in terms of assessment (Rorrison, 2008) and in promoting professional learning (Grudnoff, 2011). The study reported through the publications explicit or referred to in this exegesis focused on the development of a mobile application (‘app’) to address the problems of assessment and professional growth. It was a specific response to the emerging use of mobile devices …

The Distribution And Trophic Ecology Of Golden Ghost Crabs (Ocypode Convexa), Caitlin Rae

Theses: Doctorates and Masters

Sandy beaches make up approximately three-quarters of the world’s shorelines. They are important ecosystems, hosting abundant invertebrate macrofaunal communities that provide food resource for vertebrate predators such as shorebirds, seabirds, marine mammals and fish. Although possessing a terrestrial appearance, food input on sandy beaches is derived predominantly from the sea. Such food input includes detrital matter, mostly in the form of wrack, and has the potential to support a great diversity of species, as well as stabilising energy fluxes and dynamics of consumer populations. The movement of detritus, along with other vectors such as organisms and nutrients, across ecosystem boundaries …

The Online Student Experience: An Exploration Of First-Year University Students’ Expectations, Experiences And Outcomes Of Online Education, Melanie Henry

Theses: Doctorates and Masters

Online higher education presents a critical opportunity to extend and diversify the student body. The Online Student Experience (OSE), and online student outcomes, however, remain shrouded in ambiguity. The literature presents conflicting reports of online education (OE) quality, confounded by a lack of appreciation for potential differences between online and on-campus education, and a diversity of interpretations for what constitutes OE. The present research conceptualises OE as representing university courses that require students to interact with instructors and course materials via the internet, with no expectation of attending a university campus. A broad student-centred perspective is notably lacking from the …

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 …

Breathing New Life: Investigating Ways To Improve The Mental Health Of People Living With Chronic Obstructive Pulmonary Disease In Western Australia, Tina Phan

Theses: Doctorates and Masters

Anxiety and depression are common comorbidities in people with chronic obstructive pulmonary disease (COPD), contributing to greater morbidity and mortality in an already vulnerable population. Despite the prevalence, few recommendations exist in global management guidelines for the detection and treatment of these comorbidities, reflecting the limited literature available on effective strategies for dealing with mental health issues in COPD populations. There is promising evidence that cognitive behavioural therapy (CBT) improves mental health outcomes in people with COPD. However, investigational studies have commonly reported participants’ lack of transport, lack of time and illness as barriers to recruitment and successful completion. This …

Comparative Pairs Judgements For High-Stakes Practical Assessments, Hendrati Nastiti

Theses: Doctorates and Masters

Assessment of practical tasks, as opposed to that of theoretical tasks, has been considered to be problematic, mainly because it is usually resource intensive and the scoring is subjective. Most practical tasks need to be assessed on site or involve products that need to be collected, stored, or transported. Moreover, because practical tasks are generally open-ended, and therefore subjective, there is concern over the reliability of the scores. In high-stakes assessment, these problems are even more challenging. There is a need for an assessment method that could overcome these problems. In this study, such a method that will be referred …

An Investigation Into Trust And Security In The Mandatory And Imposed Use Of Financial Icts Upon Older People, David Michael Cook

Theses: Doctorates and Masters

Care needs to be taken to reduce the number of people who are fearful and mistrustful of using ICT where that usage is forced upon them without choice or alternative. The growing incidence of mandatory and imposed online systems can result in confusion, misuse, fear, and rejection by people with only rudimentary ICT skills. A cohort where a high percentage of such people occur is older people, defined in this study as people over the age of 60 Examples of compulsory ICT interactions include some banks limiting bank statement access through online rather than paper-based options. Other examples include the …

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.

Ucs And Cbr Behaviour Of Perth Sandy Soil Reinforced With Waste Tyre Fibres And Cement, Seyed M. A. Bazazorde

Theses: Doctorates and Masters

Weak and unsuitable soil conditions have always caused problems for civil engineers during the construction of structures. To avoid problems in a cost-effective manner, proper and reliable solutions need to be developed. Fibre reinforcement and cement stabilisation are the most efficient and common methods in geotechnical engineering applications when engineers have problematic soil conditions. These methods can be used in different applications, such as pavement layers, retaining walls and slopes.

Over the past three decades, many studies have been done to investigate the effects of adding synthetic and natural fibres to soil as the reinforcing material alone or with cement. …

An Integrated System To Design Machine Layouts For Modular Special Purpose Machines, Uday Hameed Farhan

Theses: Doctorates and Masters

This thesis introduces the development of an integrated system for the design of layouts for special purpose machines (SPMs). SPMs are capable of performing several machining operations (such as drilling, milling, and tapping) at the same time. They consist of elements that can be arranged in different layouts. Whilst this is a unique feature that makes SPMs modular, a high level of knowledge and experience is required to rearrange the SPM elements in different configurations, and also to select appropriate SPM elements when product demand changes and new layouts are required. In this research, an integrated system for SPM layout …

Design, Implementation And Evaluation Of The Impact Of A Body Image Professional Development Program For Early Childhood Educators, Karen Lombardi

Theses: Doctorates and Masters

Poor body image is a serious public health concern globally, and may lead to the development of poor mental and physical health, as well as eating disorders. Body image concerns were once believed to arise during puberty, though it is now reported children as young as three years of age present with such problems. Early intervention is therefore an important strategy to improve mental and physical health outcomes for very young children, and educators are an obvious conduit to build confidence, self-esteem and resilience of such children. In order for them to adequately fulfil this role, educators must first understand …

Young People Who Fireset In Western Australia: Peer Group Influences And Impulsiveness Trump Consequences, Catherine Analise Timms

Theses: Doctorates and Masters

The paradoxical character of fire is perfectly captured by the juxtaposition between the initial ease and excitement of lighting fires, and fire’s destructive and uncontrollable nature. Australia is fire prone with its hot, dry climate, volatile vegetation and urban sprawl surrounded by bushland. Since an estimated 50% of fires lit in Australia are deliberate (Stanley & Read, 2016) the problem of intentional firesetting cannot be overstated. This thesis argues that youth firesetting requires both macro- and microlevel approaches to appreciate the complexities of the problem, and aims to identify applicable and directed responses to minimise youth firesetting. Study one analysed …

Using Agricultural Wastes To Treat Lead-Contaminated Water In Western Australia, Hanie Hashtroudi

Theses: Doctorates and Masters

Aqueous solutions are becoming increasingly contaminated in all parts of the world (2015). Heavy metals are toxic contaminants that are mainly distributed in urban stormwater run-off and industrial wastewaters as a result of some mining operations, electronic assembly planting, battery manufacturing, and etching operations (Kadirvelu et al. 2001). Pb (II) is a heavy metal that causes significant damage in the human body. Drinking lead-contaminated water even at low concentrations may cause lifethreatening conditions such as cancer, kidney damage, brain damage, and liver problems (El-Said 2010). Therefore, it is necessary to remove lead from aqueous solutions.

Several conventional physical, chemical, and …

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 …

Effects Of Long-Term Participation In Tennis On Cognitive Function In Elderly Individuals, Scott Culpin

Theses: Doctorates and Masters

Many studies have reported the relationship between exercise and cognition with conflicting results. This may be due to differences in intervention durations, session lengths, intensities, and type of exercise. It has been suggested that exercises requiring greater cognitive demand such as football, basketball and racquet sports, are protective against cognitive decline, compared to less cognitively demanding exercises such as swimming, cycling and running, however, research concerning exercise types are currently limited. The present study tested the hypothesis that elderly individuals who had been regularly playing tennis more than 10 years, would have greater cognitive function than those who had been …

Exploring The Preparedness Of Novice (Student) Paramedics For The Mental Health Challenges Of The Paramedic Profession: Using The Wisdom Of The Elders, Lisa Holmes

Theses: Doctorates and Masters

This study investigates the preparedness of novice (student) paramedics for the mental health challenges of the paramedic profession and identifies the coping strategies used by veteran paramedics to successfully meet these challenges. The lived experience of veteran paramedics is utilised to provide this important assistance.

Initially, two surveys were developed and administered to 16 course coordinators and 302 students of the 16 accredited undergraduate degree paramedicine courses across Australia and New Zealand, to identify the perceived need (for preparation) within the curriculum. In addition, the anticipations, confidence and fears of novice (student) paramedics, course coordinators and veteran paramedics were also …

High-Intensity Interval Eccentric Cycling: Acute And Chronic Effects, Marcin Lipski

Theses: Doctorates and Masters

Eccentric cycling training has been prescribed in continuous and low intensities protocols, based on concentric cycling parameters. While the lower metabolic demand of eccentric than concentric cycling is advantageous for clinical or ‘at-risk’ populations, it is a disadvantage for cardiovascular and pulmonary adaptations. High-intensity interval protocols may increase both, strength and endurance. Thus, this research project compared i) an incremental concentric and eccentric cycling test until exhaustion for the relationship between power output and physiological parameters <Study1>; ii) interval and continuous eccentric cycling protocols for oxygen consumption, perceived exertion and enjoyment <Study 2>; and iii) aerobic performance, muscle …

How Do National Employment Policies Influence Human Resource Practices? A Comparative Study Of The Integrated Resort And Hotel Industry In Macau And Singapore, Poh Chong Danny Ng

Theses: Doctorates and Masters

Asia’s growth in prominence over the last decade is a phenomenon that has seen some governments and international financial institutions defining the twenty-first century as the Asian Century, in which Asia will be the focus of economic growth (Kohli, Sharma & Sood, 2011). The wealth in the major economies of Asia will see an increase in a dominant middle-income group, with strong spending power not only in terms of lifestyle domestically, but also internationally. This group’s quest for the finer things in life will transform the hospitality industry in countries such as Singapore and Macau: both are international metropolises with …

The Value Of Animal Behaviour As A Bio-Indicator Of Restoration Quality, Floyd Holmes

Theses: Doctorates and Masters

Woodland restoration is a complex endeavour, and restoration ecology as a scientific discipline requires constant re-assessments and adjustments if it is to improve outcomes and better provide for biodiversity. The promise of effective restoration is often used to justify destructive processes that affect many of the world’s ecosystems. It is therefore imperative that those promises can be met, which comes down to restoration ecologists’ and land managers’ capacity to predict and facilitate desirable ecological changes in a timely and socio-economically responsible manner. As perspectives have changed, and knowledge has been gained over the past few decades there have been several …

Selling The Modern Day Tribe: The Commodification Of Rave Culture, Duncan Martin Barnes

Theses: Doctorates and Masters

This thesis examines youth and rave culture from the late 1980s to the present. It considers the history as well as the global and local impact of rave. I provide a visual ethnographic study from 1999-2014, based on my work as a commercial photographer of the Perth, Western Australian scene. While critically reflecting on existing subcultural research this thesis adds another dimension – the effect that global corporations have had in reshaping subcultural practices, specifically the commodification of rave culture in the form of the contemporary electronic dance festival.

The research incorporates both qualitative and quantitative data to interrogate media …

An Investigation Into The Creation Of Goal Scoring Opportunities In Women’S International Football; And A Comparison To Men’S International Football, Mark Scanlan

Theses: Doctorates and Masters

Football is the most popular sport in the world, played in over two hundred countries and it is governed by the Fédération Internationale de Football Association (FIFA), who host a World Cup every four year for both men and women. Women’s football is growing in terms of popularity, with this growth in popularity, research into the women’s game has begun to emerge. However, to date there is very little published research in women’s football that describes effective attacking strategies and the creation of goal scoring opportunities (GSO). Video of each match (52) from the Women’s World Cup (Canada 2015) was …

Meeting Place An Exhibition – And – Locating The Country: An Australian Bricoleuse’S Inquiry An Exegesis, Annette Nykiel

Theses: Doctorates and Masters

This practice-led PhD research investigated alternate forms of articulation to relate stories of place-making, as narrative or object, and added threads to the complex meshwork and herstory of the Country. The research was conducted in ‘The Country’, of the north-eastern Goldfields and Yalgorup Lakes in Western Australia. These two non-urban sites provided unique experiences of the bush, local people’s stories and understandings of time. The research investigated the implications of non-urban spaces as studios in relation to the concepts of place, time and narrative.

This research was, in part, experiential and drew on an absorbed embodied awareness of notions of …
