This exit examination is tailored to mimic the NCLEX-RN® blueprint; thereby this examination may reveal the nursing students' readiness for the NCLEX-RN®.

The purpose of this study was to determine if there was a relationship between nursing student test-taking motivation and exit …

Improving Dysarthric Speech Recognition By Enriching Training Datasets, Sophie Cullen

Dissertations

Dysarthria is a motor speech disorder that results from disruptions in the neuro-motor interface and is characterised by poor articulation of phonemes and hyper-nasality and is characteristically different from normal speech. Many modern automatic speech recognition systems focus on a narrow range of speech diversity therefore as a consequence of this they exclude a groups of speakers who deviate in aspects of gender, race, age and speech impairment when building training datasets. This study attempts to develop an automatic speech recognition system that deals with dysarthric speech with limited dysarthric speech data. Speech utterances collected from the TORGO database are …

Measuring And Comparing Social Bias In Static And Contextual Word Embeddings, Alan Cueva Mora

Dissertations

Word embeddings have been considered one of the biggest breakthroughs of deep learning for natural language processing. They are learned numerical vector representations of words where similar words have similar representations. Contextual word embeddings are the promising second-generation of word embeddings assigning a representation to a word based on its context. This can result in different representations for the same word depending on the context (e.g. river bank and commercial bank). There is evidence of social bias (human-like implicit biases based on gender, race, and other social constructs) in word embeddings. While detecting bias in static (classical or non-contextual) word …

Development Of An Explainability Scale To Evaluate Explainable Artificial Intelligence (Xai) Methods, Stephen Mccarthy

Dissertations

Explainable Artificial Intelligence (XAI) is an area of research that develops methods and techniques to make the results of artificial intelligence understood by humans. In recent years, there has been an increased demand for XAI methods to be developed due to model architectures getting more complicated and government regulations requiring transparency in machine learning models. With this increased demand has come an increased need for instruments to evaluate XAI methods. However, there are few, if none, valid and reliable instruments that take into account human opinion and cover all aspects of explainability. Therefore, this study developed an objective, human-centred questionnaire …

This paper uses one such method to load subsequent online news pages instantly without buffering. In an online browser experiment with 38 participants, an increase in reading speed in the scrolling mode was found at a level …

Schooled To The Streets? Exploring The Relationship Between K-12 Educational Experiences And Early Careers In Activism, David Abraham Castro

Dissertations

Since the late eighteenth century, organizing and activism have been part of the urban landscape, from the labor organizing of Eugene Debs in the early twentieth century to the community organizing work of Saul Alinsky during the 1950s and 1960s. The development of community organizers is strongly tied to local institutions such as factories, houses of worship, and schools. For many youths in Chicago, schools often become the sites of political and social awakening and lead to activism beyond the schoolhouse. Within the current context of urban education scholars, practitioners, policymakers, and community organizers alike agree that the perspectives of …

School Leaders’ Assessment Of Teachers’ Preparedness For Culturally Responsive Teaching, Victoria Maria Siliunas

Dissertations

Societal and school inequities continue to be highlighted via widening achievement gaps that adversely impact historically marginalized groups of students and their communities. An acknowledgement of the importance of developing teachers who are prepared to work with students of culturally differing identities from their own in the day-to-day work of teaching has inspired a shift in language and practice from a more general multicultural approach to a culturally responsive teaching methodology in which a purposeful inclusion of the ethnic and cultural backgrounds of students is prioritized. Addressing challenges schools face related to cultural difference between teachers and the students they …

An Analysis On Network Flow-Based Iot Botnet Detection Using Weka, Cian Porteous

Dissertations

Botnets pose a significant and growing risk to modern networks. Detection of botnets remains an important area of open research in order to prevent the proliferation of botnets and to mitigate the damage that can be caused by botnets that have already been established. Botnet detection can be broadly categorised into two main categories: signature-based detection and anomaly-based detection. This paper sets out to measure the accuracy, false-positive rate, and false-negative rate of four algorithms that are available in Weka for anomaly-based detection of a dataset of HTTP and IRC botnet data. The algorithms that were selected to detect botnets …

An Investigation Of The Relationship Between Subjective Mental Workload And Objective Indicators Of User Activity, Greg Byrne

Dissertations

Whilst the concept of physical workload is intuitively understood and readily applicable in system design, the same cannot be said of mental workload (MWL), despite its importance in our increasingly technological society. Despite its origin in the mid 20th century, the very concept of ”mental workload” is still a topic of debate in the literature, although it can be loosely defined as “the amount of mental work necessary for a person to complete a task” (Miller, 1956; Longo, 2014). Several methods have been utilized to measure of MWL, including physiological methods such as neuro-imagery, performance-based metrics, and subjective measures via …

Evaluating The Performance Impact Of Fine-Tuning Optimization Strategies On Pre-Trained Distilbert Models Towards Hate Speech Detection In Social Media, Aidan Mcgovern

Dissertations

Hate speech can be defined as forms of expression that incite hatred or encourage violence towards a person or group based on race, religion, gender, or sexual orientation. Hate speech has gravitated towards social media as its primary platform, and its propagation represents profound risks to both the mental well-being and physical safety of targeted groups. Countermeasures to moderate hate speech face challenges due to the volumes of data generated in social media, leading companies, and the research community to evaluate methods to automate its detection. The emergence of BERT and other pre-trained transformer-based models for transfer learning in the …

Phase Rule And Isomorphism Principle Analysis Of Critical Phenomena In Multicomponent Systems, Xingjian Wang

Dissertations

This dissertation investigates critical phenomena in the liquid mixture near its liquid-liquid critical solution temperature, especially for critical effects on solubilities and turbidities. According to the Griffiths-Wheeler rule, the critical effect is expected for the derivatives of a density variable with respect to a field variable in the system with less than two fixed density variables. The power of the phase rule for solving the number of fixed densities and predicting critical effects is examined in multicomponent systems with the numbers of fixed density variables between zero to two. When the excess solid solute is added into a binary liquid …
