Performance And Interpretation: Beethoven's Opus 110, Izaac J. Masters

Theses: Doctorates and Masters

Within the context of professional music making, an increasing number of pianists use both modern and historical pianos as a matter of course. Yet, not infrequently, it seems that there is little awareness of how the inherent acoustic characteristics of each instrument may be used to inform interpretation, and the instrument-specific pianistic techniques that are needed if interpretation is to be optimised. This study explores issues of interpretation and performance as applied to Beethoven’s Piano Sonata in Ab major, op. 110. Three different performative interpretations of the sonata are constructed, each relating to a specific grand piano––made by, respectively, Conrad …

The Concept And Role Of Meaningful Work In The Context Of Pakistan – An Exploratory Study Of Junior Doctors, Abid Hussain

Theses: Doctorates and Masters

Over the past decade, the concept of meaningful work has gained increased attention from human resource management, organisational science, and management scholars. This can be largely attributed to the growing global concern for the wellbeing and meaningful engagement of individuals in the workforce, especially since the COVID-19 pandemic. The literature on meaningful work reveals that there are multiple perspectives and theoretical approaches to the conceptualisation of meaningful work which can be found primarily within Western societies and Western scholarship and are often based on Western worldviews. Most of the quantitative and qualitative empirical studies adopt a reductionist approach and tend …

Quantifying And Managing The Impact Of Electric Vehicles On Power Distribution Assets, Pravakar Pradhan

Theses: Doctorates and Masters

Concern over the transportation sector’s greenhouse gas (GHG) emissions, which make up around 23% of all energy-related CO2 emissions, has grown in recent years. The widespread use of electric vehicles will be the primary strategy for tackling this issue. About 30% of the world’s passenger vehicle fleet is anticipated to be electrified by the year 2040. Moreover, the existing power distribution assets are already operating near their nominal capacities, and most of them have been in service for more than 25 years. Replacement of these assets will be very costly and disruptive to the power distribution network. Ergo, the main …

An Examination Of Kinanthropometric And Physical Injury Risk Factors In Elite Australian Football, Callum J. Mccaskie

Theses: Doctorates and Masters

Kinanthropometric assessment is an integral part of understanding an athlete’s physical profile and readiness for competition. This typically includes a variety of different assessments which serve to quantify body shape, proportion, and composition in a bid to understand human physiology. Common assessments include stature, body mass, limb ratios, body circumferences, body mass index, skinfold testing, body composition testing, and musculoskeletal morphological evaluations. Specifically, kinanthropometric evaluations have involved the characterisation of athletes according to sport, sex, competition level and playing position. While this has provided researchers and practitioners with greater insight into athletic phenotypes, more purposeful kinanthropometric assessments which focus on …

Carbon Geosequestration And Enhanced Oil Recovery In Geological Formations: Multi-Scale Analysis, Auby Baban

Theses: Doctorates and Masters

Carbon geosequestration (CGS) has been recognized as a strategic solution to prevent/counter the catastrophic consequences of climate change. However, despite recent cutting-edge technical research, predicting quantitative CO2 trapping in geological formations via capillary trapping is currently scarce. Moreover, several aspects of multiphase flow characteristics of CO2/brine/rock systems, that greatly impact carbon capture and containment security, require further investigations. Furthermore, combining carbon geosequestration with Enhanced Oil Recovery (EOR) is an efficient and economically attractive technology to reduce global warming caused by emissions of anthropologic CO2 from the combustion of fossil fuels, whereby it offsets some of the costs of CO2 extraction. …

In recent times, governments have been using their procurement function to drive innovation in firms’ product outcomes and to improve operational activities that pose sustainability challenges. Ghana, for example, is currently advancing and upgrading its public works infrastructure with revenues from its commercialised oil reserves to match and improve its anticipated middle-income economy status. Faced with several sustainability challenges, such as environmental pollution and resource depletion, desecration of cultural heritage sites and exposure of labour force to poor working conditions, public works infrastructure procurements constitute a larger proportion of government procurement expenditure, globally, compared with the procurement of goods and …

Fagotte Forgotten? The Bassoon In The Early Symphonies Of Mozart, Haydn And Contemporaries In The 1760s And 1770s, Katherine J. Walpole

Theses: Doctorates and Masters

This research project investigates the role of the bassoon in the basso of the early symphonies of Mozart, Haydn and Contemporaries in the 1760s and 1770s. It draws on surviving primary source material pertaining to bassoonists and orchestral practices across Europe before 1780. Autograph scores of Haydn, Mozart and his contemporaries usually scored early Classical symphonies for pairs of oboes, horns, two violin sections, viola and basso. Modern scholars have described these compositions as symphonies for pairs of oboes, pairs of horns and strings, and have translated basso to mean cellos and basses. Eliminating the eighteenth-century term basso has also …

Downstream Air Dilution And Biomass Pulverisation Into Bluff-Body And Swirl Stabilised Confined Turbulent Jets, Syed E. Gillani

Theses: Doctorates and Masters

Bluff-body and swirl-stabilised turbulent annular flows (single phase and multi-phase) find broad practical utility, especially in high-power non-premixed combustion applications. Their significance stems from features like their characteristic recirculation zones and intense upstream turbulence, both of which promote air-fuel mixing and aid in flame stabilisation. Moreover, in response to the push for low-emission and carbon-neutral fuel sources, there's a growing emphasis on integrating biomass, especially in its pulverised form, into major power generation systems. In practical gas turbine combustors featuring bluff-body and swirl stabilised flame burners, the incorporation of (air) side dilution jets plays a crucial role. These jets influence …

The Cartographies Of Place: Approaches To Audio-Visual Composition Incorporating Aspects Of Place, Wing S. Tsang

Theses: Doctorates and Masters

Incorporating aural and visual elements of a place in a composition serves as a powerful way of exploring the intersection of time, history and geography associated with a location. The combination of these elements acts as an invitation for deeper engagement by offering multiple perspectives of place. One way of exploring these intersections is through incorporating aspects of place—in the form of field recordings, field footage and cartographical information—into audio and audio-visual work, where spatial and physical information can be situated as a way of representing an individual’s surroundings and subjective realities of place. This practice-led exegesis aims to explore …

Experimental Investigation Of The Interface And Wetting Characteristics Of Rock-H2-Brine Systems For H2 Geological Storage, Mirhasan Hosseini

Theses: Doctorates and Masters

The projected rise in demand for hydrogen (H2) production is a response to several factors, including greenhouse gas emissions caused by burning fossil fuels, depletion of fossil fuel reserves, and their uneven distribution around the earth. Thus, increased requirement for large-scale hydrogen storage solutions is anticipated to overcome imbalance between energy demand and supply. Deep underground formations such as salt caverns and porous reservoir rocks (e.g., depleted hydrocarbon reservoirs and deep saline aquifers) are necessary to achieve such volumes in practice. This process is known as underground hydrogen storage (UHS) which is technically very similar to underground natural gas storage. …

An Interpretive Description Study Of The Views And Experience Of Obstetric Fistula Risk Factors Among Women Attending Evangel Vesico Vagina Fistula Centre In Nigeria, Lydia Babatunde-Bulndi

Theses: Doctorates and Masters

An obstetric fistula is a hole between the birth canal and the bladder or rectum, which is caused by prolonged, obstructed labour without intervention. Sufferers of obstetric fistula may experience chronic urinary and/or faecal incontinence. Although obstetric fistula is directly caused by prolonged obstructed labour, factors such as unskilled birth assistance can increase fistula risk indirectly. Harmful traditional practices, such as female genital mutilation, lack of formal education, illiteracy, poverty, limited social role for women, malnutrition, early marriage before the full development of the pelvis, and a lack of emergency obstetric services are some of the additional factors associated with …

Student Works

This problem-solution analysis analyzes factors impeding safe and orderly evacuations for the Federal Aviation Administration (FAA). Although rarely used, evacuation procedures are critical for keeping passengers safe during emergency situations. However, there are flaws in these procedures and many factors exist which make aircraft evacuations slow and dangerous. During a situation in which time is of the essence, these impediments can make the difference between an incident and a fatal accident. This report focuses on data gathered through full-scale evacuation simulations and analyzes shortcomings and strengths in three accidents. This information is then compared to current procedures and regulations that …

Solar Sailing Adaptive Control Using Integral Concurrent Learning For Solar Flux Estimation, Luis Enrique Mendoza Zambrano, Riccardo Bevilacqua

Student Works

In the interest of exploiting natural forces for propellant-less spacecraft missions, this investigation proposes an adaptive control strategy to account for unknown parameters in the dynamic modeling of a reflectivity-controlled solar sail spacecraft. A Lyapunov-based control law along with integral concurrent learning is suggested to accomplish and prove global exponential tracking of the estimated parameters and states of interest, without satisfying the common persistence of excitation condition, which in most nonlinear systems cannot be guaranteed a priori. This involves estimating the solar flux or irradiance from the Sun to account for uncertainty and variation over time in this value. To …

Alternatives To Reducing Aviation Fuel-Burn With Technology: Fully Electric Autonomous Taxibot, Denzil Neo

Student Works

Aircraft taxiing operations in the aerodrome were identified to consume the most jet fuel apart from the cruise phase of the flight. This was also well supported by various research associating taxi operations at large, congested airports, with high jet fuel consumption, high carbon emissions, and noise pollution. Existing literature recognised the potential to address the environmental issues of aerodrome taxi operations by operating External or Onboard Aircraft Ground Propulsion Systems (AGPS). Designed to power aircraft with sources other than their main engines, external Aircraft Ground Power Systems (AGPS) have shown the potential to significantly cut jet fuel consumption and …

Experiential Learning Projects As Assessment In Initial Teacher Education, Renee Crawford, Louise E. Jenkins, Lydia Wan

Australian Journal of Teacher Education

In a rapidly changing global environment, Initial Teacher Educators (ITE) have a responsibility to role-model contemporary teaching approaches, which develop graduates who think creatively and flexibly in educational workplaces. An important aspect of this work is supporting pre-service teachers (PSTs) to understand how to design assessments which facilitate a deep understanding of student learning. This learning can be achieved through the implementation of assessments which model contemporary practices and enrich student learning in ITE courses. This paper discusses new ways to consider the purpose of assessment by focusing on Experiential Learning (EL) as a form of assessment in ITE. This …

Towards Pre-Service Teachers’ Theory-Praxis Nexus In Early Years English And Literacy Education: A Pilot Study, Maryanne Pale, Sarah Ohi, Lyn Kee

Australian Journal of Teacher Education

International literature highlights that a perennial challenge for initial teacher educators is to guide Pre-Service Teachers (PSTs) to develop a comprehensive understanding of the relationship between theory and practice. Whilst there is a growing body of research that examines the relationship and/or the gap between theory and practice in teacher education, there remains a paucity of research that examines this phenomenon in the teaching of English and literacy units in higher education. This pilot study examined how PSTs from two Australian universities made connections and/or links (nexus) between their academic knowledge (theory) and professional experience (praxis) for the teaching of …

Nature Of Science: Examining Science Teachers’ Knowledge And Their Instructional Practices, Sharon Bramwell-Lalor

Australian Journal of Teacher Education

This case study focused on a university teacher-education course that included NOS content. An adapted questionnaire was used to collect quantitative data on 83 secondary science teachers’ views about three NOS themes before and after completing the course. Qualitative data were collected from eight of the teachers who were observed teaching during their field experience after completing the course. The teachers’ post-course mean NOS scores were statistically significantly higher than their pre-course scores (t (65) =-10.08, p<.001; Cohen’s d = 1.4). Despite the favourable NOS knowledge among the science teachers, low levels of NOS portrayal were observed in their instructional practices. These findings point to some success in explicitly addressing NOS in science education content courses. However, they raise questions about the transferability of teachers’ NOS knowledge into their classrooms. The findings have implications for teacher-preparation programmes regarding durability of NOS knowledge.

Six Modes Of Giving Pedagogy For Engagement And Wellbeing – For Teachers And Students, Thomas W. Nielsen, Jennifer S. Ma

Australian Journal of Teacher Education

The present study took place across two outdoor education trips to the Great Barrier Reef with two groups of college students (N = 36; 16-19 years), five staff, and one of the authors (TWN). The aim was to explore how an explicit understanding and implementation of the wellbeing research around cultivating generous behaviour for meaningful happiness could be ‘experienced’ by staff and students and articulated as an educational framework, or ‘pedagogy’. Hermeneutic phenomenology was used to record and interpret pedagogical transactions of giving. Six repeated themes were identified: (1) exploration, (2) modelling, (3) explicit instruction, (4) incidental learning, (5) crisis …
