From Point Estimates To Predictive Distributions In Machine Learning Models - A Statistical Importance Sampling Framework, Giuseppina Carannante

Theses and Dissertations

In this thesis, we leverage powerful statistical frameworks for optimal sequential estimation and tracking in non-linear and non-Gaussian dynamical models, which enjoy proven (asymptotic) optimality properties. Initially, we build upon our previous work, which employed first-order Taylor series approximation to propagate the first two predictive moments, to derive Bayesian encoder-decoder networks. This work introduced the notion of dense, pixel-level uncertainty map that is crucial in fields, such as autonomous vehicles and medical segmentation. We then extended the Bayesian framework to an ensembling scheme based on ensemble Kalman Filtering (EnKF). While EnKF represents the predictive distribution with an ensemble of draws, …

First Episodic Atmospheric Deposition Of Nutrients To Utah Lake: Statistical Analysis And Characterization, Cristian Alun Dorrett

Theses and Dissertations

Atmospheric deposition (AD) is a significant but poorly understood source of nutrients to many aquatic systems around the world. Accurate characterization of the nutrient budgets of aquatic systems is critical to good management decisions, so a better understanding of AD-related nutrient loads is essential, especially for water bodies where nutrient loads from atmospheric deposition are significant. Due to its large surface area, proximity to Great Basin dust sources, high values of atmospheric particulates due to inversions, and the high phosphorus content of local soils, Utah Lake, in the semi-arid Utah Valley, USA, experiences significant phosphorus loading from AD. The lake …

Not In This House, Satan! An Integrative Framing Analysis Of Body-Positive Posts On Instagram, Gladys Mana Momade

Theses and Dissertations

Scholars have associated the portrayal of idealized images of the body on social media with the negative body image of users, which manifests as several mental health problems such as eating disorders, body dissatisfaction, body dysmorphic disorder, depression, and anxiety in users. To tackle this issue, body-positive (BoPo) influencers on Instagram, having achieved a state of positive body image, post verbal and visual messages to advocate against normative ideologies that foster the negative body image of social media users. These messages have some implications for health communication and body image research. This study analyzes body-positive influencers’ self-assertion and self-expression in …

Permanent Passive Fire Protection Against Wildland-Urban Interface Fires, Makenzie Wilson

Theses and Dissertations

The average intensity and frequency of wildland fires have been on the rise over the years, leading to an increase in the risk to homes located in the Wildland-Urban Interface (WUI). Fire suppression is the most used method of wildland fire control, but this suppression can cause wildland fires to become more frequent and devastating. Increased development in the WUI also puts these homes at greater risk. Current methods of passive fire protection are effective, but these methods are expensive, time consuming to set up, and not fully effective. This research proposes a permanent passive fire protection system that is …

Dopamine D2 Receptors As A Peripheral Biomarker For Brain Dopamine Levels, Christina Small

Theses and Dissertations

The ability to objectively index dopamine (DA) levels in the brain has the potential to revolutionize the field of neuropsychopharmacology, as having a peripheral biomarker of brain DA would enable the objective monitoring of the progression of Parkinson's disease (PD) and other DA-dependent psychiatric states. Of particular relevance to commercialization, it would provide an objective measure of treatment efficacy. We used a DA-depletion approach to determine if peripheral D2Rs are a biomarker for brain DA; mainly, the 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) neurotoxin model and PD subjects, which are well-known models of DA depletion in the midbrain of rodents and humans, respectively. Dopamine …

A lack of support from administration is one of the most common reasons special educators are leaving the field of education (e.g. Sutcher, et al., 2016). The purpose of this study was to better understand how special educators view and experience support from their administrators. This study surveyed 23 special educators in public schools in Illinois and Wisconsin to identify, what do special educators identify as essential actions of supportive administrators and how administrators have shown or missed opportunities to show support toward special educators. Researchers found five major themes of supportive actions including, (1) promoting collaboration amongst staff, (2) …

Body In Rebellion: The Closing Body, Romantic Mesmerism, And Gothic Doubles In Hogg's Justified Sinner, Elizabeth E. Hinds

Theses and Dissertations

This study explores the western Romantic period as a transition between the medieval “open body” and the modern “closed body.” It focuses on “closing body” phenomena such as “mesmerism” (i.e. animal magnetism), somnambulism, substance abuse, and the “second-self,” including notions of the subconscious and the trope of gothic Doppelgängers. This study draws from many pieces of western Romantic literature but is most centered around James Hogg’s 1824 The Private Memoirs and Confessions of a Justified Sinner. This new reading of Hogg’s novel suggests a core theme of body anxiety, rather than theological dispute.

A Language-Model-Based Chatbot That Considers The User's Personality Profile And Emotions To Support Caregivers Of People With Dementia, Yeganeh Nasiri

Theses and Dissertations

Chatbots are programs that mimic human conversation using Artificial Intelligence (AI). Recent advances in natural language pro- cessing pave the way for chatbots to generate more human-like responses. Therefore, chatbots are finding more complex tasks to perform, such as emotional support which requires both understanding emotions and the ability to properly respond to them. This work presents a chatbot capable of identifying the user's personality and creating responses based on that. During this process, emotion detection is being used to detect and react to users' emotions. The chatbot uses a dynamic knowledge graph to save information as the conversation goes …

Unsupervised Categorical Clustering On Labor Markets, Matthew James Steffen

Theses and Dissertations

During this "white collar recession,'' there is a flooded labor market of workers. For employers seeking to hire, there is a need to identify potential qualified candidates for each job. The current state of the art is LinkedIn Recruiting or elastic search on Resumes. The current state of the art lacks efficiency and scalability along with an intuitive ranking of candidates. We believe this can be fixed with multi-layer categorical clustering via modularity maximization. To test this, we gathered a dataset that is extensive and representative of the job market. Our data comes from PeopleDataLabs and LinkedIn and is sampled …

Halophilic Genes That Impact Plant Growth In Saline Soils, Mckay A. Meinzer

Theses and Dissertations

Many plants are highly sensitive to salt in the soil, and their growth and yield can be greatly hindered by as little as less than 1% salt concentration in the soil. Additionally, soil salinity is a growing issue globally and affects significant areas in Utah. Halophytes are plants that are adapted to grow in saline soils and have been widely studied for their physiological and molecular characteristics, but little is known about their associated microbiomes. Bacteria were isolated from the rhizosphere and as root endophytes of Salicornia rubra, Sarcocornia utahensis, and Allenrolfea occidentalis, three native Utah halophytes. Several strains of …

Development And Validation Of A Spanish Nutrition Screening Tool For Hispanic American 3 To 5-Year-Olds, Denisse Arias Olivas

Theses and Dissertations

Latinos comprise 18.9% of the population in the United States and are the largest and fastest growing minority group. Obesity prevalence was 26.2% among Hispanic children compared to 16.6% among non-Hispanic White children. The obesity epidemic among Latino children has been growing rapidly over the past three decades. Multiple barriers, such as lack of culturally appropriate screening tools, language, and lack of access to nutritional assessment and expert consultation, prevents screening of Latino children and further nutritional guidance. For this reason, prevention efforts such as the use of nutritional screening tools is required for early intervention, more so with populations …

Real-Time Imaging And Measurement Of Compartmentalized Redox Shifts Using Novel Redox-Sensitive Biosensors: Implications In Developmental Toxicology, Brandon Mitchell Davies

Theses and Dissertations

Glutathione (GSH) is a small antioxidant in the body and exists in large quantities compared to other antioxidants. The GSH redox state (Eh) helps developmental processes, however, when the GSH Eh is disrupted, cells may undergo significantly poor developmental pathways, possibly leading to long-lasting damages. Similarly, NADPH and Thioredoxin redox states can have a major impact on cellular function, viability, and response to both endogenous and exogenous toxicants. Subcellular, compartmentalized redox environments during normal or perturbed situations, specifically in the cytosol, mitochondria, and nucleus, are not well understood. Here, using the P19 neurogenesis model of cellular differentiation, the kinetics of …

Detecting Physiological Concentrations Of Alzheimer’S Associated Amyloid-Β Protein Utilizing A Cell-Based Response, Brittany Elizabeth Watson

Theses and Dissertations

Alzheimer’s disease (AD) is characterized symptoms of cognitive impairment resulting from blood-brain barrier (BBB) breakdown and neuronal cell death. AD is associated with aggregated amyloid-β (Aβ) plaques deposited around brain vasculature and within the brain. Changes in the brain occur up to 20 years before symptoms arise; however, there is currently no pre-symptomatic detection method available for AD. An intact BBB requires tight junction proteins (TJs) that render relatively high transendothelial electrical resistance (TEER). AD-associated breakdown of the BBB correlates with vascular Aβ deposition, suggesting that aggregated, pathological Aβ can modulate TEER. We explore leveraging this cellular response for early …
