Examination Of Obtained And Expected Cognitive Performance Of English Learners: An Evaluation Of Broad Ability Composites Versus Aggregate Mean Scores, Nicole Brozyna

Theses and Dissertations

The United States population continues to shift towards a majority rich in cultural, ethnic, and linguistic minorities (Rhodes et al., 2005). Within the education system, school psychologists are challenged with the task of conducting nondiscriminatory assessment of English Learners (ELs), while also adhering to the standards for ethical practice. In recent years, minority students have too frequently been placed in special education settings without sufficient support to signify need of a classification. To provide equitable and fair assessments to ELs in schools, clinicians require the knowledge necessary to understand the influence of cultural and linguistic developmental factors that affect performance. …

The Impact Of An Experiential Financial Literacy Workshop On First-Grade Students’ Comprehension Of Financial Concepts, Deirdre Donnelly

Theses and Dissertations

The purpose of this study was to investigate the impact that an experiential financial literacy workshop has on first-grade students’ comprehension of financial concepts. Financial literacy is a lifelong skill. It is essential for children to establish and maintain the financial literacy skills necessary to be successful in money matters throughout their lives; yet many young children are not being taught financial concepts (Center for Financial Security, 2016). In addition, a person’s financial attitudes are shaped in childhood (Drever et al., 2015). Currently, elementary schools throughout the United States are not consistently creating age-appropriate financial literacy curricula for children (Collins …

Biological And Chemical Evaluation Of Amide-Based Cjoc42 Derivatives As Potential Gankyrin-Inhibitors For The Treatment Of Breast, Lung, And Liver Cancer, Benita Britton-George

Theses and Dissertations

Gankyrin is an ankyrin-repeat protein overexpressed in certain cancers and is responsible for cell growth and proliferation. Gankyrin is important to the development of many types of cancer, including breast, lung, and liver cancer. Consequently, gankyrin and its various protein-protein interactions, are prospective therapeutic targets for inhibiting the progression of certain cancers. In 2016, the first small molecule inhibitor of gankyrin, cjoc42, was discovered and subsequently demonstrated modest antiproliferative activity against liver cancer cells. Previous work from our lab demonstrated that replacing the sulfonate ester of cjoc42 with an amide group significantly improved gankyrin binding while enhancing antiproliferative activity against …

The Psychometric Properties Of A Spanish Version Of The Attitudes And Beliefs Scale-2 Short Form In A Mexican Sample, Verónica Compeán

Theses and Dissertations

The Attitudes and Beliefs Scale 2-Short Form (ABS2-SF) is one of the most widely used measures of irrational and rational beliefs central to Rational Emotive Behavior Therapy (REBT). While evidence supports its reliability and validity in English-speaking populations, little is known about its applicability across cultural and linguistic groups. This study investigated the psychometric properties and cultural validity of the Spanish version of the ABS2-SF in a Mexican sample (n = 579) collected from undergraduate students in Tampico, Mexico, and compared them with English-speaking American non-clinical samples (n = 1,167). Using a bifactor multi-group confirmatory factor analysis (MG-CFA), I examined …

Neural Congruency Contrastive Learning Framework Validation Using Artificially Created Eeg Data For Dyslexia Research, Jacqueline M. Torres

Theses and Dissertations

Analysis of electroencephalogram (EEG) recordings in children with dyslexia has been commonly used to explore the neural mechanisms underlying reading disorders. Yet, challenges such as low signal-to-noise ratio (SNR), high inter-subject and inter-trial variability, and the inherently multivariate nature of EEG signals hinder the isolation of neural components elicited during reading diagnostic tests. To mitigate these challenges, the neural-congruency analysis framework was recently proposed, leveraging traditional machine learning optimization methods to incorporate domain knowledge about the congruency of neural responses across participants (i.e., consistent neural responses among proficient readers). However, the application of deep learning techniques, specifically contrastive learning, remains …

Investigation Of The Binding Mechanisms Between Naphthenic Acids And Humic Acid Using Raman Spectroscopy And Computational Modeling, Jaelyn N. Palmer

Theses and Dissertations

The oil sand regions in Alberta, Canada have proven to be costly to the environment despite its economic benefits. The toxins produced during oil processing are sent to tailing ponds to be recycled, though often leaking into nearby waterways and soil. Naphthenic acids, NAs, are one of the most common toxins produced and have shown to be toxic to aquatic life, animals, and humans. As there is dissolved organic matter in tailing ponds and surrounding environments, tailing ponds often lead to NAs coming in contact with organic material. Humic acid, HA, is a major soil component that has been suspected …

Leveraging Distributed Semantics From Deep Learning Architectures For Literature-Based Discovery, Clint A. Cuffy

Theses and Dissertations

Literature-based discovery (LBD) is a scientific process that introduces methods to automatically identify novel insights between non-interacting sets of literature. To date, numerous statistical and machine learning-based methods have been applied in the biomedical domain to find treatments for diseases such as Raynaud's disease, Parkinson's disease, and Multiple Sclerosis. However, the lack of standardized practices and creation of bespoke methodologies produces a scenario where the adoption of LBD remains challenging in real-world systems. Our work addresses these concerns through the improvement of five critical areas: 1) error propagation within LBD's a priori dependent tasks, 2) exploring the integration of modern …

Enhancing Irs Localization Via Ml-Driven Aoa And Distance Estimation, Nikhila Kotlapara Surendran

Theses and Dissertations

Beyond Homogeneity: Exploring Causal Heterogeneity In Psychopathology, Philip B. Vinh

Theses and Dissertations

Traditional models in psychiatric research often impose assumptions of causal homogeneity, treating population-level associations as reflective of uniform underlying mechanisms. This dissertation challenges that assumption by introducing statistical and machine learning frameworks designed to detect and model causal heterogeneity in the development of psychopathology. Central to this approach is the advancement of finite mixture structural equation modeling (FM-SEM) to identify latent subgroups characterized by distinct, and sometimes opposing, causal pathways.

The dissertation comprises three integrated empirical studies. The first introduces mixDoC, a finite mixture extension of the classical Direction of Causation (DoC) model applied to twin data, enabling the detection …

Modeling The Impacts Of The Current And Projected Temperatures On Spongy Moth Population Dynamics, Adrienne B. Spring

Theses and Dissertations

The spongy moth (Lymantria dispar) is an invasive forest pest that has caused significant ecological damage across the United States. Its invasion front is shaped by a number of factors, including temperature in both the northern and southern regions. With ongoing climate change, areas that were previously uninhabitable may become increasingly favorable for moth population establishment and expansion, while other areas may experience thermal stress limiting persistence. This study develops a temperature-driven population model to analyze how temperature affects the spongy moth population dynamics along the invasion front. This model incorporates temperature effects on fecundity, stage-specific survival rates, …

Predictive Inference For Ion Concentration With Machine Learning And Bayesian Methods, Alexandra B. Ulbing

Theses and Dissertations

Ultraviolet--visible (UV--Vis) spectroscopy produces high-dimensional signals that are strongly collinear, shift with concentration, and exhibit heteroskedastic, non-Gaussian noise. These features make supervised regression from spectra to ionic concentrations statistically challenging and limit the reliability of methods that assume linear structure or homoscedastic errors.

This dissertation develops two complementary frameworks for prediction and uncertainty quantification in UV--Vis spectroscopic regression: (1) frequentist stacked ensembles combined with distribution-free conformal prediction, and (2) Bayesian hierarchical modeling and Bayesian stacking. Together, they provide a unified view of model-based and distribution-free uncertainty across nickel and nickel--cobalt datasets.

The frequentist component builds ensembles of Functional Data Analysis …

A Fault-Tolerant Exchange-Coupled Spin-Ensemble Qubit At Elevated-Temperatures, Aniruddha Chakraborty

Theses and Dissertations

This thesis introduces a novel qubit architecture: the ferromagnetic exchange-coupled spin ensemble qubit (E-qubit), designed to address the noise-induced instability. In this work, the time evolution of the ensemble’s density matrix is studied using the Liouville–von Neumann equation. To benchmark against a single-spin qubit, the gate fidelity of an E-qubit is computed in the presence of thermal noise. Coherence time is also analyzed under identical thermal condition and a linear scaling is observed with qubit size . The results show that, at 6 K , the gate fidelity error (0.7 % ) of the seven- spin ensemble is an order …

Imagine Being Free: Decolonizing Actor Training In University And Conservatory Programs, Hope R. Ward

Theses and Dissertations

While blackface is considered the first proper form of American theater, I want to consider how the auction of enslaved Africans functioned as the original form of American theater. The auction block acted as a kind of interactive performance in which enslaved bodies were surveilled and evaluated as a kind of spectacle. In many ways, the auction block inaugurated White viewing practices of the Black body that reverberated in the day-to-day practices of slavery and subsequent visual media like the refashioning of blackface minstrel tropes within contemporary entertainment (plays, television, film). In Imagine Being Free: Decolonizing Actor Training in University …

Design And Fabrication Of Tpms-Based Bone Scaffolds: A Cost-Effective Approach Using Plga-Nha And 3d-Printed Pva Molds, Yasser Ahmed

Theses and Dissertations

This thesis introduces a new cost-effective method for fabricating bone scaffolds from triply periodic minimal surface (TPMS) geometries—namely Gyroid and Diamond structure—using a poly(lactic-co-glycolic acid)-nanohydroxyapatite (PLGA-nHA) composite and 3D-printed polyvinyl alcohol (PVA) molds. Current TPMS scaffold fabrication techniques depend on costly laser-based techniques like selective laser sintering and thus remain inaccessible. Herein, we reveal a cost-effective and repeatable indirect approach via fused deposition modeling (FDM) for printing water-soluble PVA molds, which are then iteratively cast filled with a PLGA-nHA solution. The protocol was optimized through concentration modulation and controlled evaporation of the solvent for optimum infiltration and uniformity in the …
