Surface Plasmons For Enhanced Metal-Semiconductor-Metal Photodetectors, Ayman A. Karar

Theses: Doctorates and Masters

Surface Plasmon Polaritons (SPPs) are quantized charge density oscillations that occur when a photon couples to the free electron gas of the metal at the interface between a metal and a dielectric. The extraordinary properties of SPP allow for sub-diffraction limit waveguiding and localized field enhancement. The emerging field of surface plasmonics has applied SPP coupling to a number of new and interesting applications, such as: Surface Enhanced Raman Spectroscopy (SERS), super lenses, nano-scale optical circuits, optical filters and SPP enhanced photodetectors. In the past decade, there have been several experimental and theoretical research and development activities which reported on …

A Review Of The Policy Development Processes That Relate To The Inclusion Of People With A Disability In Sport : Some Western Australian Evidence, Helen Cunningham

Theses: Doctorates and Masters

In the late 1960s, there was a major change in social policy and legislation in developed countries that improved the rights and opportunities for people with a disability in all aspects of society, including sport. In 1992, in concert with the general acceptance of the social model of disability, Australia enacted legislation making it illegal to discriminate against a person with a disability; this encouraged their inclusion into the community (Australian Sports Commission, 2005; Doll-Tepper, 1999; Thomas & Smith, 2009).

In order to meet the obligations of anti-discrimination legislation, Australian sport organisations became active in preparing policy frameworks to guide …

Understanding And Disrupting Institutional Settings : Using Networks Of Conversations To Re-Imagine Future Farming Lives, Robert Campbell

Theses: Doctorates and Masters

Farmers in Australia and elsewhere face the challenge of remaining profitable whilst dealing with adverse structural arrangements and public expectations to better manage environmental degradation. This thesis draws on arguments that dominant paradigms in agricultural science and environmental management have often been ineffective in addressing these apparently competing demands and appear poorly suited to ‘messy’ situations characterized by uncertainty and complexity, and in which diverse stakeholders are motivated by varying goals and values. Engaging with such situations requires a philosophy and methodology that accepts a multiplicity of perspectives and which seeks to learn about and reflect upon novel ways of …

Exploring Predictors Of Sport Commitment In Coaches, Erin Bormann

Theses: Doctorates and Masters

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

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

Theses: Doctorates and Masters

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

Optimal Control Of Power Quality In Microgrids Using Particle Swarm Optimisation, Waleed Abood Baddai Al-Saedi

Theses: Doctorates and Masters

Driven by environmental protection, economic factors, conservation of energy resources, and technical challenges, the microgrid has emerged as an innovative small-scale power generation network. Microgrids consist of a cluster of Distributed Generation units that encompass a portion of an electric power distribution system and may rely on different energy sources.

The issue of power quality is significant as it directly affects the characteristics of the microgrid’s operation. This problem can be defined as an occurrence of short to long periods of inadequate or …

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

Theses: Doctorates and Masters

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

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

Theses: Doctorates and Masters

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

Representation And Symbolic Politics In Indonesia : An Analysis Of Billboard Advertising In The Legislative Assembly Elections Of 2009, Eva Leiliyanti

Theses: Doctorates and Masters

The overarching characteristic of the 2009 legislative elections lay in the legislative candidates’ politics of image. It stemmed from the amendment to the election Law no. 10/2008 article 214 that ostensibly cut off the parties’ power in determining their candidates without the public’s “direct” consent. The public was then given a direct opportunity to choose and vote for their preferred candidates in the 2009 elections. This marked the emergence and proliferation of the candidates’ image construction, especially in the “outdoor” political arena. Billboards were chosen as the most effective outdoor advertising medium to introduce the candidates and propagate their slogans …

Pictures In Words : Indexing, Folksonomy And Representation Of Subject Content In Historic Photographs, Brian Stewart

Theses: Doctorates and Masters

Subject access to images is a major issue for image collections. Research is needed to understand how indexing and tagging contribute to make the subjects of historic photographs accessible.

This thesis firstly investigates the evidence of cognitive dissonance between indexers and users in the way they attribute subjects to historic photographs, and, secondly, how indexers and users might work together to enhance subject description. It analyses how current indexing and social tagging represent the subject content of historic photographs. It also suggests a practical way indexers can work with taggers to deal with the classic problem of resource constraints and …

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

Theses: Doctorates and Masters

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

Metapopulation Theory Explains Black-Stripe Minnow (Pisces: Galaxiidae, Galaxiella Nigrostriata) Distribution In Seasonal Wetlands In South-West Western Australia, David M. Galeotti

Theses: Doctorates and Masters

The objective of this project was to determine if Galaxiella nigrostriata populations could belong to a metapopulation. Metapopulation theory describes how multiple populations with occasional connectivity are a ‘population of populations’. Some populations’ habitats have optimal conditions (source habitats), others experience regular extinctions (sink habitats). Connectivity allows repopulation of extinct or uninhabited habitats. Galaxiella nigrostriata occurred randomly in 11 seasonal wetlands in the Kemerton wetland complex in south-west Western Australia over a 16 year period. The wetlands did not appear to be connected.

Around 70% of wetlands on the Swan Coastal Plain in south-west WA have been filled or degraded …

Evaluating Residential Satisfaction With An Innovative Dual Water Supply System In Water Sensitive Urban Development, Raju S. Dhakal

Theses: Doctorates and Masters

The Australian water industry is facing two major challenges: a rise in water demand due to a growing population and a decrease in rainfall availability due to a drying climate. This situation has triggered a re-evaluation of traditional water schemes and promoted consideration of alternatives for sustainable urban water management. One possibility is to replace drinking water usage in garden and outdoor irrigation with non-potable groundwater. This could save almost half of the water supplied in the residential sector, which is the biggest consumer of scheme water in most Australian cities. A major hurdle for the success of such fit-for-purpose …

School Administrators' Beliefs Regarding The Relationship Between School Improvements And Formal School Registration, Harm P. Witten

Theses: Doctorates and Masters

In 2004, the Government of Western Australia introduced an inspection-type formal school registration process for Non-Government (Independent) Schools, fulfilling the legislative requirement of a new School Education Act of 1999 (Part 4, Sec.159). This formal school registration process featured twelve criteria that are used to evaluate the quality of education. The government claimed that it would ensure a good education for all students in Western Australian, including those students enrolled in Independent Schools.

Stakeholders Perspective On Sustainable Technology Selection To Achieve Zero Carbon Retail Buildings, Syeda Zainab, Wei Pan, Steve Goodhew, Alba Fuertes

School of Art, Design and Architecture

In the design and construction of sustainable retail buildings, there are various stakeholders involved with the overall aim of selecting appropriate sustainable technologies to reduce energy consumption and carbon emissions. Previous studies and literature review indicate there is no comprehensive selection process to assist stakeholders. This can be classified as a complex multi-criteria decision problem due to the high number of alternatives, potential solutions and variety of stakeholders (e.g. clients, professional advisors, end-users) with multiple, often conflicting, objectives leading in turn to the slow take-up of sustainable technologies. There is a demand for a systematic and effective evaluation tool for …
