Hierarchical Multi-Label Text Classification In Earth Science Datasets, Rajashree Dahal

Theses

This thesis addresses the challenging problem of hierarchical multi-label text classification and introduces a novel zero-shot approach that recommends the label up to the depth of hierarchy in which it is confident. In order to validate the efficacy of the proposed method, we experimented using various potential embedding models such as text-embedding-ada-002, mpnet-all, instructor embeddings, and nasa-smd-ibm-st on Earth science datasets. The experimental results reveal that all considered embedding models surpass the baseline model supervised learning classifier, demonstrating the superiority of the proposed zero-shot approach. This proposed solution can minimize the label imbalance problem typically observed in the supervised learning …

Data Fusion Approach To Assessing Hurricane Impacts On Us Gulf Coast Wetlands: Case Studies Of Hurricanes Ida And Ian, Trent W. Cowan

Then the Evangelical movement will be surveyed to gain an understanding of its identity from a sociological and theological perspective with special attention on its soteriological framework, customary spiritual disciplines, and general attitudes toward mysticism (defined as direct experience of God through apophatic, …

Traumatic Heterotopic Ossification: Pathophysiological Mechanisms, Epidemiological Characteristics, And Risk Factors, Nicola Kate Foster

Theses

Traumatic heterotopic ossification (tHO) refers to the complication of pathological formation of ectopic bone in soft tissues, which follows tissue insult secondary to burn, neurological and orthopaedic injury [2]. Common to these diagnoses is the involvement of central and or peripheral nervous system trauma. Although known risk factors are associated with developing tHO, the underlying cellular and molecular mechanisms are not fully understood. Research to date, primarily in single injury cohorts, has provided minimal translatable results [2]. Thus, clinical guidelines for early screening and prophylactic drug therapy are lacking, and treatment options are limited. To move the body of knowledge …

The Philosophy Behind The Vatican's Approach To Relations With China, John Ogilvie

Theses

The Vatican has always played a significant role in global politics, and it continues to do so in the contemporary World. The Vatican’s relations with the People’s Republic of China (PRC) have drawn considerable attention in recent years, especially following the signing of the 2018 Vatican-China Agreement. Some scholars and commentators suggest that the 2018 Agreement and its terms represent a significant deviation from the norm in Vatican diplomacy. In light of that controversy, the present thesis provides an introductory examination of the philosophy that possibly guides the Vatican’s relations with the PRC and the implications this holds for an …

An Ontology Based System For Cancer Diseases Knowledge Mining, Shinead Casey

Theses

National cancer registries play an important role in understanding the patterns and trends of cancer diseases, prevention methods, and treatment management. However, issues arising from data silos and an inability to link heterogeneous data sources have led to problems within the healthcare industry. This became apparent in Ireland in 2018 when Dr Scally’s scoping inquiry into the CervicalCheck controversy highlighted patient safety issues relating to disjointed data and an inability to link datasets.

Worldwide, semantic technologies are being utilised for their ability to link diverse data and enhance analytical capabilities. Therefore, this thesis will examine the use of a knowledge …

Screening And Analysis Of The Urobiome For The Production Of Antimicrobial Peptides To Target Uropathogenic Escherichia Coli, Jennifer Jones

Theses

Urobiome research is currently at a nascent stage, due to a previously incorrect assumption that the bladder is a sterile environment. Improvements in bacterial culturing and DNA sequencing techniques have revealed a diverse resident bacterial community within the urinary tract (urobiome). As global incidences of multidrug- resistant urinary tract infections (UTIs) continue to increase, so too does the demand for novel antimicrobial therapies. Due to its relatively understudied nature, the urobiome represents a reservoir that could be mined as a potential source of novel antimicrobial compounds (e.g., bacteriocins). The aim of this thesis was to identify urobiome bacteriocins that could …

An Investigation Into The Nature Of The Knee Pain Experience In People With Knee Osteoarthritis, Gemma Mary Orange

Theses

Knee osteoarthritis poses a substantial and escalating socioeconomic burden globally, exacerbated by demographic trends towards an aging population, sedentary lifestyles and increasing obesity rates. Defined by knee pain and functional limitations (Wood et al., 2023; Zhang, Doherty, et al., 2010), traditional approaches have viewed knee OA related pain and disability primarily through a biomedical lens, linking symptoms directly to structural damage and advocating surgical interventions such as total knee arthroplasty to address presumed causative pathology (Bunzli et al., 2019; Darlow et al., 2018). Despite the capacity of surgery to ameliorate structural pathology, patient centred outcomes vary considerably. Up to 30% …

A Paradox Theory Approach To Investigating Individual Level Responses To Corporate Social Responsibility In Small To Medium Enterprises, Muhammad Abdulsater

Theses

In Australia, small and medium-sized enterprises (SMEs) occupy important positions within their communities, contributing to employment and national economic growth. Despite their significance, it remains unclear how SME owners, as individuals, navigate and respond to the tensions arising from their unique business characteristics and the adoption of social and environmental activities. This research aims to bridge this knowledge gap by investigating how SME owners manage and respond to paradoxical tensions in implementing social and environmental responsibility practices within the SME context. The conventional definition of corporate social responsibility (CSR) does not integrate with the lexicon or landscape of SMEs. This …

The research’s four aims were to gather and compile archaeological evidence associated with the Afghans and their religious lives as Muslims; describe …

Prevalence Of Peristomal Skin Complications In The First 12 Weeks Post-Discharge Following Urinary/Faecal Stoma Formation Surgery, Tania Norman

Theses

Background

An ostomy is a surgically created opening and can be performed to divert faecal effluent by exteriorisation of a segment of the small bowel otherwise known as the ilium, or from the large bowel otherwise known as the colon. A urinary diversion of effluent generally involves exteriorisation of a segment of ileum into which the ureters have been anastomosed. The exteriorised segment of bowel is referred to as a stoma and individuals who have had a stoma created often refer to themselves as an ‘ostomate’. The skin surrounding a stoma is referred to as peristomal skin.

Peristomal skin complications …

Analysing The Prevalence Of Servant Leadership Characteristics And Cultural Values In A Uae-Based Multinational And Multicultural Workforce, Richard John Atkinson

Theses

In an increasingly virtual, pandemic-affected working environment, cross-cultural and people-centric leadership approaches are needed. Scholars have explored leadership effectiveness under different conditions and influences. However, in the body of leadership literature, there is scant attention to the variance across cultures for servant leadership to manage workers effectively.

This mixed-methods study explores whether servant leadership relates to cultural characteristics across three different nationalities in a UAE-based multinational organisation, providing a more comprehensive understanding of these relationships and differences and employees' perceptions. The quantitative method is examined using context-specific knowledge and the qualitative method explores the nuances of participant responses making the …

Deterring The Digital Dragon, Bryn Lacey

Theses

Australia’s 21st century has been heavily influenced by a growing number of cyber incidents ranging from individuals causing extraordinary damage to state-based attacks from adversary states such as China. Focusing on state actors in the cyber domain, this thesis investigates Martin Libicki’s cyber-deterrence framework, with a specific emphasis on the employment of deterrence by punishment, and applies this concept to the case study of the relationship between Australia and China.

"Where You Do Not Wish To Go": Petrine Ministry Between Charism And Institution, In The Thought Of Erich Przywara And Hans Urs Von Balthasar, Daniel Uremovic

Theses

Since the First Vatican Council’s solemn definition of papal primacy and infallibility, the Catholic ecclesial consciousness has been shaped by a unique form of devotion to the office of the Supreme Pontiff. While the scope of these charisms had been clearly defined and delimited, a sentiment described as “creeping infallibility” has nevertheless complicated the proper understanding of the Petrine office and its demands on the faithful. Before the episcopal college, local church communities, the laity at large, and the individual churchman, this office has been regularly viewed in tensions that feel the prerogatives either of institution or charism threated. Even …

Challenging The Myth Of Consensus: Irish Australian Voices In Perth During The Great War Conscription Referendums, Alexander Mcclure

Theses

The controversial conscription referendums of 1916 and 1917 in Australia saw a resurgence of religious sectarianism and a perceived entanglement with the aftermath of political violence in Ireland. Examining the voting outcomes in all the Australian states for the referendums may suggest that Western Australia stood against the nationwide trend of rejecting Prime Minister William Hughes’s proposals for compulsory military service. Analysis over the last thirty years has challenged this idea, which is that Western Australia showed a unique, widespread consensus during the Great War period. A greater understanding has developed with the increasing digital accessibility of wartime primary sources, …

A shadowgraph system for implementing shock wave tracking analysis is employed within a supersonic test section with an inlet freestream Mach number of 1.54. Unsteady surface static pressure and temperature variations are measured at streamwise locations along the bottom wall. Unsteady temperature data are used …

Isolation, Purification, Crystallization And Preliminary X-Ray Data Analysis Of The B Family Dna Polymerase From Thermococcus Thioreducens, Emika Miyamoto

Theses

Family B DNA polymerases are the core polymerizing enzymes that carry out the essential process of DNA replication in many Archaeal organisms. Archaea depend on the unique properties of their DNA polymerases to faithfully replicate DNA within extreme environments. Variation in the catalytic properties of DNA polymerases from different organisms can be elucidated through detailed structural analysis by means of macromolecular X-ray crystallography. Crystallization is the crucial and bottleneck step in the process of determining the protein’s three-dimensional structure by X-ray diffraction—essentially no crystal, no structure. This study optimizes the isolation and purification of recombinant DNA polymerase B from Thermococcus …

Spectropolarimetric Properties Of Vortex Retarders, Ella Elizabeth James

Theses

Vortex retarders are unique optical elements that create a uniform electric field phase retardance, but the traditional fast axis varies azimuthally over the area of the optic. This affects the radial and azimuthal polarization components of the incoming beam. The vortex retarders discussed here generate TEM10 and TEM20 Laguerre-Gaussian beams. While several varieties of these TEM10 and TEM20 vortex retarders exist, designed to function at specific wavelengths–and a few studies have reported their use at those wavelengths–almost no data exists detailing their polarimetric properties outside those wavelengths. Using a Mueller matrix spectropolarimeter with dual-rotating retarders, the polarization properties of four …

Generation Of True Random Numbers With A First Order Chaotic Circuit, Austin Davis

Theses

True randomness backed by first principles theory is surprisingly rare in physically implemented circuit for cybersecurity applications. This thesis provides an illustrative case of a chaotic one-dimensional map circuit with a design driven by a need for rudimentary theory concerned with the limits of its entropy production. Analysis, simulation, and hardware measurements are evaluated against statistical randomness tests issued by the National Institute of Standards and Technology. Interestingly, the results provided here highlight strong relationships between first principles theory of design and measured results when varying parameters. We observe matching characteristics between analytic, simulated and measured hardware results for NIST …

Towards Algorithm Selection For Efficient Search-Based Software Engineering, Niranjana Deshpande

Theses

In Search-Based Software Engineering (SBSE), metaheuristic search algorithms are used to construct software by combining components that fulfill diverse user and business requirements. These search algorithms typically employ randomization to accurately and efficiently evaluate numerous component combinations using limited computational resources. As a result, several search algorithms have been proposed to address SBSE problems, each with varying solution quality guarantees and computational resource usage. Recent research has demonstrated that search algorithms exhibit complementary behavior, that is, different search algorithms outperform each other on specific problem instances in terms of computational resource usage and solution quality. Problematically, current SBSE approaches do …

Analyzing Trust In Automation Using Large Language Models, Derek Koehl

Theses

This thesis explores the measurement of trust in the context of human interactions with automated systems. Trust is influenced by factors like perceived ability, benevolence, and integrity which presents a measurement challenge. Given the lack of a universally accepted model for trust, there is an abundance of trust measurement methods in the literature. This research aimed to ascertain the reliability of NLP-based measurements to determine whether such methods can shed light on the dimensionality of trust as a construct and to isolate a Linguistic Fingerprint™ of trust. The results lent support to trust as a unidimensional construct. There was little …
