Understanding Administrative Support From The Perspective Of Special Educators, Morgan M. Glasson

Theses and Dissertations

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 …

Network Representation Theory In Materials Science And Global Value Chain Analysis, Mats C. Haneberg

Theses and Dissertations

This thesis is divided into two distinct chapters. In the first chapter, we apply network representation learning to the field of materials science in order to predict aluminum grain boundaries' properties and locate the most influential atoms and subgraphs within each grain boundary. We create fixed-length representations of the aluminum grain boundaries that successfully capture grain boundary structure and allow us to accurately predict grain boundary energy. We do this through two distinct methods. The first method we use is a graph convolutional neural network, a semi-supervised deep learning algorithm, and the second method is graph2vec, an unsupervised representation learning …

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 …

A Comparison Of The Vascular Response To Acute Sauna Heating In Young And Middle-Aged Adults, Olivia Kathryn Leach

Theses and Dissertations

BACKGROUND: Age-related declines in endothelial function have been well documented with larger declines observed in middle-aged. Passive heat exposure has been shown to be a promising method to improve vascular endothelial health, with sauna specifically being linked to reduced risk of cardiovascular disease. Increases in blood flow and shear rates associated with heat exposure are often considered to have a major influence on the observed improved endothelial function following heat exposure. The magnitude of these changes in response to sauna have not yet been defined. Therefore, the purpose of this study is to quantify and compare the vascular response to …

Mental Health And Well-Being Among Refugee-Aid Workers In Egypt, Mahmoud Khattab

Theses and Dissertations

Refugee-aid workers are positioned in the middle between the realities and suffering of refugees and the detachment of the organizations and their donors. They carry the burden of accommodating both realities as the connecting link between both worlds. This study has found that the continuous exposure to the traumatic stories that refugees go through has negative implications on the mental health and well-being of the workers providing services to these refugees. Additionally, a lack of resources and negative management cultures impose stress on the refugee-aid worker. Negligence and failure by organizations to mitigate these stressors lead to a deterioration in …

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 …

Face Validation Of A Spanish Non-Invasive Prenatal Screening Knowledge Scale, Kenya Michelle De Leon

Theses and Dissertations

Non-invasive prenatal screening (NIPS) provides risk assessment for chromosome aneuploidy in pregnancy. Previous studies in the United Kingdom and United States have attempted to measure patient knowledge, decisional conflict, and informed choice in cohorts of English-speaking pregnant patients who elected NIPS (Griffin et al., 2023; Lewis et al., 2016). However, knowledge scales utilized in these studies have not been validated. The current study was conducted in order to assess face validity of a Spanish NIPS knowledge scale that was originally written in English. This scale was developed as part of a larger project to ultimately provide more validated research measures …

Effect Of Action Selection Demands On The Execution Of Goal-Directed Reaches, James Garrison Riedy

Theses and Dissertations

A well-studied model of cognitive motor function is the process of action selection. It is unclear how the planning demands of a reaching movement interact with the added complexity of s election. Therefore, this thesis investigated the effect of adding selection demands to the performance of skilled reaches in a virtual environment. Thirty young, healthy participants reached ipsilaterally or contralaterally with either their dominant (right hand) or non-dominant (left hand) under two conditions: execute only (EO) and action selection (AS). Selection accuracy was higher for the EO condition than the AS condition for both arms and both directions (left arm: …

Participants were recruited to complete an online survey that exposed them to manipulations of narrative …

Structural And Immunological Characterization Of Inhaled Allergens And Their Complexes With Antibodies, Kriti Khatri

Theses and Dissertations

Allergy is an outcome of an allergen-antibody reaction (1). Potent airborne allergens from dust mites and pets are major causative factors for allergic conditions among predisposed individuals. Group-2 allergen Der p 2 from Dermatophagoides pteronyssinus is a major allergen which causes allergic conditions in more than 80% of mite-allergic subjects (2). Similarly, airborne allergen Can f 1 from dog (Canis familiaris) is also a major risk allergen which affects 10-20% of the population worldwide (3). Considering the increasing prevalence of inhalant allergens in the environment, antigenic characterization is crucial for improving allergy diagnostics and management. This study focuses …

“We Are Created Inferior To Men”: Leveraging Horsemanship To Reinforce Gender Expectations, 1830-1861, Gabrielle Marie Mccoy

Theses and Dissertations

Horses have played a central role in human society since 3500 BCE when humans began domesticating and riding horses in large numbers. Horses continued to be important to human society during the nineteenth century as people used horses to drive industrialization, manage plantations, and transport goods, among other uses. Although historians and anthropologists have long extolled the horse’s laboring value, this paper views the horse and horsemanship (i.e., horseback riding, horse training) in a social context. Through the examination of newspapers, fictional literature, and manuals, this paper argues that Americans used horses and horsemanship to reinforce antebellum gender expectations. Reinforcing …
