The study addresses three research questions: (1) the general themes in Undset’s Catholic non-fiction; (2) the contemporary relevance of these writings; and (3) whether Undset merits the designation “Catholic apologist.” In its method, the thesis employs textual analysis of Undset’s essays, articles …

Study Of An Evolutionary Sequence Of Nearby, High-Excitation Bipolar Planetary Nebulae With Alma And Hst, Paula M. Moraga Baez

Theses

Planetary nebulae (PNe) reveal the near-final stages of the evolution of intermediate-mass (1-8 solar mass) stars, immediately after such stars shed their envelopes through copious asymptotic giant branch (AGB) mass loss. PNe reveal products of intermediate-mass stellar nucleosynthesis just before they enrich the interstellar medium, and their central stars provide subjects for studying the origins of white dwarfs and interacting binary systems involving compact objects. The processes that shape planetary nebulae and determine their chemistries can be unveiled through multiwavelength observational studies of molecule-rich PNe ranging from young and rapidly evolving nebulae, such as NGC 7027, NGC 6302, and NGC …

A Public For The Problem: Vocabularies Of Belonging At The Climate Precipice, Louisa Stredwick

Theses

This study proposes the central concepts of belonging and vocabulary to critically analyse and recompose current approaches to more-than-human relationship that are inadequate and counterproductive. Contemporary vocabularies of belonging are inadequate because they fail to account for the practicalities of an expansive human and more-than-human ‘we’, and they are underpinned by extractivist or idealist logics. They are counterproductive because they carry embedded dualisms that often directly counter intended messages of inherent relationality. A largely theoretical work, the thesis is informed by a field philosophy approach in the Environmental Humanities, working alongside the Martuwarra (Fitzroy) River, in North-Western Australia, and its …

A Comprehensive Study On Explainable Artificial Intelligence : A User-Centric, Cognitive Workload, And Feasibility-Driven Analysis, Josiah Taylor

Theses

Explainable Artificial Intelligence aims to open up the “black box” of artificial intelligence, thereby improving user trust, decreasing cognitive load, and improving task performance. As the number of machine learning models has grown, so has the number of explanation methods, making it necessary to select the most suitable explanation method for a given context. However, current selection methods often fail to account for all the factors that contribute significantly to an explanation method’s suitability. This thesis proposes a novel methodology for selecting and evaluating explanation methods. Subjective workload, objective performance, and feasibility are considered. This three-pronged “pitchfork” methodology is put …

Development Of A Constitutive Model Free Method To Determine Full-Field Stresses Based Upon Fundamental Physics Principles, Joel David Barnes

Theses

Advances in imaging techniques allow for the determination of full-field displacements and strains during materials testing. However, most analysis techniques rely on strain gages and virtual extensometers instead of utilizing all available full-field data. Those methods that do utilize the full-field strain and displacement measurements, such as Finite Element Model Updating and the Virtual Fields Method, must also rely on a user-defined constitutive material models to relate the stresses and strains. While these methods can provide accurate full-field stresses and insights into complex material behavior in some cases, they are constrained by the fact that they require a pre-selected constitutive …

Determination Of Material Deformation At Truly Constant Strain Rates Utilizing Full-Field Stress And Strain Measurements, Derryk Lee Daignault

Theses

The rate sensitivity of materials is an important aspect to consider when designing components; such as in manufacturing processes, aerospace vehicle impacts/propulsion systems, and automobile collisions. Characterizing a material’s rate sensitivity can be expensive and time consuming due to multiple tests being necessary at each given strain-rate to fully characterize the response. This project proposes a methodology to determine the material response at multiple truly constant true strain rates from a single test using non-uniform geometry and the strain localization phenomenon. Finite element simulations using Ansys LS-DYNA are used to design potential new test specimen geometries to induce constant and …

Unbound Subgenres : Overlapping Age Categories In Contemporary Romance And Their Implications, London Stevenson

Theses

This thesis aims to highlight the importance of genre labelling in contemporary romance fiction and the larger implications that come from the misuse of labels. Considerations of the genre based on narrative elements (Regis, 2003; Michelson, 2022), age categorization (Cart, 2011; Tribunella, 2007), and emerging market conditions (McAlister, 2018; Stewart, 2013) have generated considerable discussion over the last twenty-five years. While each of these scholars draws important conclusions about romance and its subgenres, none of them consider the significance of reader opinion, which is now enhanced due to literary digital spaces. In this paper, I examine nine romance novels for …

Nursing Students' Clinical Placement Experience In A Residential Aged Care Facility: A Comparative Study, Nitasha Aarni Narayan

Theses

Nursing education programs play a significant role in preparing future nurses to care for the growing number of older people who will require health care. A key component of this preparation is the learning that nursing students acquire through clinical placement experience in a residential aged care facility. This clinical placement provides them with opportunities to experience caring for older adults. However, many students are reportedly reluctant to accept clinical placement in aged care and are ill-prepared for the challenges of the residential aged care facility environment. Hence, it is important for the development of future nursing programs and the …

Vision Or Exemplification? Augustine And Aquinas On Divine Illumination, Matthew Richard Cain

Theses

Many interpreters of Thomas Aquinas since the second half of the twentieth-century emphasise the Platonist dimensions of his thought, particularly his metaphysics. This contrasts with, and is a shift away from, the dominant Aristotelian interpretations of previous generations. Aquinas’s theory of knowledge, however, tends still to be interpreted in Aristotelian terms, according to which Augustine’s Platonist illuminationism is replaced by a Peripatetic emphasis on sensation and abstraction in the soul.

This thesis reexamines the role of illumination in Augustine and Aquinas’ theories of knowledge. It asks whether scholarship today ought to reconceive the relationship between these two major thinkers in …

Theses

This study explores the relationship between an Australian Catholic university’s talk about its ethos and the walk of pedagogic practice. In particular, this study focuses on the talk of Catholic ethos at the macro level of the University as an organisational entity and the walk of teaching first year undergraduate students at the micro level of teachers as individual entities.

The ecological systems theory of Bronfenbrenner (1979) and the bioecological Process Person Context Time Model of Bronfenbrenner and Morris (2006) were utilised to interrogate this relationship. Along with a Bronfenbrennerian lens, the method of analysis adopted in this study was …

Learning To Be 'With Woman': The Lived Experience Of Studying Midwifery, A Phenomenological Study, Ashlee Guerin

Theses

At the heart of midwifery lies a philosophy grounded by the principle of being ‘with woman’. This core philosophy defines the profession itself, reflected in the etymology of the word midwife, derived from the Anglo-Saxon terms mid (with) and wif (woman), reflecting a tradition of relational care embedded within the profession. Understanding and embodying this philosophy is fundamental for midwifery students, as it shapes their professional identity, informs clinical decision-making, and underpins the provision of care that is safe, respectful and in partnership with women across their childbearing journey. Learning to be ‘with woman’ fosters respect, advocacy, and partnership, ensuring …
