Optimisation Of Stand-Alone Hybrid Energy Systems For Power And Thermal Loads, Barun Kumar Das Jan 2018

Optimisation Of Stand-Alone Hybrid Energy Systems For Power And Thermal Loads, Barun Kumar Das

Theses: Doctorates and Masters

Stand-alone hybrid energy systems are an attractive option for remote communities without a connection to a main power grid. However, the intermittent nature of solar and other renewable sources adversely affects the reliability with which these systems respond to load demands. Hybridisation, achieved by combining renewables with combustion-based supplementary prime movers, improves the ability to meet electric load requirements. In addition, the waste heat generated from backup Internal Combustion Engines or Micro Gas Turbines can be used to satisfy local heating and cooling loads. As a result, there is an expectation that the overall efficiency and Greenhouse Gas Emissions of …


Is Leadership The Key To Public Sector Retention In Regional Western Australia? An Exploratory Study, Damian Lambert Jan 2018

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.


Seed Morphology, Dormancy And Germination Of South-West Australian Ericaceae, Michael Just Jan 2018

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 Photographic Other: Paradox In The Cathexis Of Longing, Alex Cilla Bradley Jan 2018

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 …


The Online Student Experience: An Exploration Of First-Year University Students’ Expectations, Experiences And Outcomes Of Online Education, Melanie Henry Jan 2018

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 …

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 …


An Integrated System To Design Machine Layouts For Modular Special Purpose Machines, Uday Hameed Farhan Jan 2018

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 …

The research specifically investigated how SM is being used for project activities and the maturity of the management processes that govern SM use. Implications for …


Exploring Poor Outcomes From Quality Assurance Programs – An Analysis Based Around The Concept Of Mechanisms And The Theory Of Constraints (Toc) Thinking Process (Tp), Layla M. M. B. Al-Hameed Jan 2018

Exploring Poor Outcomes From Quality Assurance Programs – An Analysis Based Around The Concept Of Mechanisms And The Theory Of Constraints (Toc) Thinking Process (Tp), Layla M. M. B. Al-Hameed

Theses: Doctorates and Masters

Quality programs have been used by organisations since their advent in the 1930s and continue to be implemented to achieve various goals. For example, according to the International Organization for Standardization (2015) and the CASRO Institute for Research Quality (2016), organisations aim to reduce costs, gain a competitive advantage, improve the quality of their processes and products, and enhance profitability through attaining such accreditations. ISO accreditations have also been used to ensure compliance with market requirements (Williams, 2004). However, a major challenge in implementing these programs, referred to in this thesis as ‘Quality Assurance Programs’ (QAPs), is the gap that …

Bone Fracture Incidence, Measurement And Adaptation: An Exploration Through The Continuum From Incidence To Measurement And Adaptation, Mark Jenkins

Theses: Doctorates and Masters

This research encompasses four studies exploring bone adaptation, fracture incidence, and preventative measures to decrease fracture risk and increase bone health. Study one was a clinical audit exploring incidence rates for appendicular fractures in children in Western Australia over ten years. Diagnostic and remedial approaches were explored in studies two, three and four by examining the between-day reliability of upper limb scans; reliability of the osteogenic index (OI) for upper-body strength and power exercises; and the diagnostic value or utility of using pQCT in disease profiling, respectively. Fracture rates in the limbs of children were found to be increasing each …


Automated Optical Mark Recognition Scoring System For Multiple-Choice Questions, Murtadha Alomran Jan 2018

Automated Optical Mark Recognition Scoring System For Multiple-Choice Questions, Murtadha Alomran

Theses: Doctorates and Masters

Multiple-choice questions are one of the questions commonly used in assessments. It is widely used because this type of examination can be an effective and reliable way to examine the level of student’s knowledge. So far, this type of examination can either be marked by hand or with specialised answer sheets and scanning equipment. There are specialised answer sheets and scanning equipment to mark multiple-choice questions automatically. However, these are expensive, specialised and restrictive answer sheets and optical mark recognition scanners.

This research aims to design and implement a multiple-choice answer sheet and a reliable image processing-based scoring system that …

Braking Ground Reaction Force During 90deg Sidestep Cut And Its Relationship To Leg Muscle Strength, Walter Yu Jan 2018

Braking Ground Reaction Force During 90deg Sidestep Cut And Its Relationship To Leg Muscle Strength, Walter Yu

Theses: Doctorates and Masters

Previous studies on change of direction (COD) have reported that braking is an important factor for COD performance. However, previous studies have focused on the plant step and the penultimate step (PEN), thus little is known about deceleration before these steps. This study compared ground reaction forces (GRF) of two braking steps, the PEN and the step prior to PEN (PEN-1), the entry and exit velocity of the COD, and muscle function measures (leg press and leg curl one-repetition maximum, isometric and isokinetic strength, and drop jump performance) between faster and slower participants for a 90o sidestep cut. This …


The Delivery Of Primary Health Care In Remote Australian Communities: A Grounded Theory Study Of The Perspective Of Nurses, Kylie Mccullough Jan 2018

The Delivery Of Primary Health Care In Remote Australian Communities: A Grounded Theory Study Of The Perspective Of Nurses, Kylie Mccullough

Theses: Doctorates and Masters

Around 85% of Australia’s landmass is remote and sparsely populated. Across these vast areas of desert, wilderness and tropical islands, nurses provide the majority of health care services. The residents of Australia’s remote communities have poorer health status than their metropolitan counterparts. The proportion of Indigenous people is high and health and social disadvantage is widespread. The characteristics of each remote community are unique and often reflect challenges associated with distance to tertiary health services and limited health resources. As a result, nursing practice within this context is very different to other nursing contexts. Despite recognition of Primary Health Care …


Public Health Implications Of Metal Ash Concentrations From Prescribed Burns: A Study Of Open Jarrah Forests, John Edwards Jan 2018

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 Mechanics Of Front Leg Loading During Cricket Fast Bowling: Delivery Variations, Spell Demands, And The Effects Of Strength Training, Samuel J. Callaghan Jan 2018

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 …

Impact Of Biobanks On Research Outcomes In Rare Diseases:A Systematic Review, Monique Garcia Jan 2018

Impact Of Biobanks On Research Outcomes In Rare Diseases:A Systematic Review, Monique Garcia

Theses: Doctorates and Masters

Rare diseases (RDs) are a global priority yet are still under researched. When combined, RDs are common, with individual diseases numbering approximately 5,000-8,000, equating to approximately 7% of the population in Europe. Extrapolating this figure for Australia suggests that about 1.2 million people are affected by RDs, with about 400,000 of those being children. The WA Rare Diseases Strategic Framework 2015-2018, the first strategy for rare diseases in Australia, recognises that in order to alleviate the significant burden of rare diseases, innovative translational tools that facilitate research into new diagnostic and therapeutic strategies should be given priority.

Registries facilitate clinical, …


Gender Differences In Physical Performance Characteristics Of Competitive Surfers, Joanna Parsonage Jan 2018

Gender Differences In Physical Performance Characteristics Of Competitive Surfers, Joanna Parsonage

Theses: Doctorates and Masters

Competitive surfing is judged on the performance and complexity of innovative and progressive manoeuvres. As such, surfers require the physical attributes of strength and power in both the upper and lower-body in order to facilitate performance. To date, there remains limited research pertaining to the physical performance characteristics of competitive female surfers, making it difficult to quantify the current gender gap in performance attributes. Therefore, the purpose of this thesis was fivefold: (1) to describe and compare the gender differences in physical performance characteristics of competitive surfers; (2) to investigate the reliability and validity of the isometric push-up (IPU), dynamic …

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 …


Reading Between The Crimes: Online Media’S Representation Of Aboriginal And Torres Strait Islander People’S Interaction With The Criminal Justice System In Post-Apology Australia, Jonathan Cannon Jan 2018

Reading Between The Crimes: Online Media’S Representation Of Aboriginal And Torres Strait Islander People’S Interaction With The Criminal Justice System In Post-Apology Australia, Jonathan Cannon

Theses: Doctorates and Masters

Australian research confirms that Aboriginal and Torres Strait Islander people experience high levels of social inequality, racism and injustice. Evidence of discrimination and inequality is most obvious within the criminal justice system where they are seriously over-represented. The Australian news media plays a large part in reinforcing Aboriginal and Torres Strait Islander inequality, stereotypes and racist ideology within specific situations such as the Northern Territory Emergency Response and the Redfern riots. This study widens the scope from how the media reports a single criminal justice event to how the media reports Aboriginal and Torres Strait Islander people’s interaction with the …

The deployment of ultra-dense heterogeneous small cell networks (SCNs) is expected to …


Antibiotic Resistance In Gram Negative Bacteria Isolated From Fish Sold In Western Australia, Hannah Kathleen Robinson Jan 2018

Antibiotic Resistance In Gram Negative Bacteria Isolated From Fish Sold In Western Australia, Hannah Kathleen Robinson

Theses: Doctorates and Masters

Background Information The global misuse and overuse of antibiotics in human medicine and the animal production industry is contributing to the development of antibiotic resistance in bacteria. This is a serious threat to modern medicine and public health. Antibiotic resistant organisms can cause severe infections in humans which are difficult to treat, and in some cases impossible to resolve which can lead to premature death. Several studies have been conducted across the globe to assess the use of antibiotics in the seafood industry and the associated health risks, however, limited studies have recently explored this risk in an Australian setting. …


N-Glycosylation Profiles As A Risk Stratification Biomarker For Type Ii Diabetes Mellitus And Its Associated Factors, Eric Adua Jan 2018

N-Glycosylation Profiles As A Risk Stratification Biomarker For Type Ii Diabetes Mellitus And Its Associated Factors, Eric Adua

Theses: Doctorates and Masters

Worldwide, the prevalence of cardiometabolic diseases, particularly type II diabetes mellitus (T2DM), and to a lesser extent, metabolic syndrome (MetS), has increased dramatically. Despite this increase, there is still a lack of robust biomarkers for cardiometabolic diseases to secure better clinical outcomes. The enzymatic attachment of oligosaccharides (glycans) to proteins-glycosylation is of metabolic and physiological significance, as exploring aberrations of glycosylation profiles can reveal novel biomarkers. In parallel, this process could also explain the biological mechanisms that underpin a suboptimal health status (SHS), a reversible subclinical stage of a cardiometabolic disease. However, studies on the correlation between glycosylation and MetS/T2DM …


Circulating Tumour Dna: A Non-Invasive Biomarker For Melanoma, Ashleigh Cavell Mcevoy Jan 2018

Circulating Tumour Dna: A Non-Invasive Biomarker For Melanoma, Ashleigh Cavell Mcevoy

Theses: Doctorates and Masters

Cutaneous melanoma accounts for 90% of all skin cancer deaths (Balch et al., 2010) and is responsible for 3.6% of deaths from cancer in Australia (Australian Institute of Health and Welfare, 2016). Whilst early detection and successful surgical removal of primary melanomas have improved survival rates (DeSantis et al., 2014), approximately 30% of these patients will have disease recurrence at some point in their lives (Soong et al., 1992; Soong et al., 1998). This is despite being considered disease free following treatment, which may have included surgical removal of the primary and/or its metastasis/es, radiation and/or systemic therapy. Whilst the …


Young People Who Fireset In Western Australia: Peer Group Influences And Impulsiveness Trump Consequences, Catherine Analise Timms Jan 2018

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 …


Effects Of Long-Term Participation In Tennis On Cognitive Function In Elderly Individuals, Scott Culpin Jan 2018

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 …
