While It's Still Morning, Cosenza Marie Hendrickson

Theses and Dissertations

While It's Still Morning is a collection of lyric poems exploring themes of love, gratitude, and praise. The critical essay introducing the collection discusses possible pitfalls of this genre of poetry and how I've sought to avoid them. It also details qualities often present in my favorite poems (surprise, particularity, strangeness, tension, attention, allusion) and ways in which I've striven to create these qualities in my own poetry.

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 …

Finished, Shayla Frandsen

Theses and Dissertations

Sixteen-year-old Tiny Sinclair begins her first year at Charity Ambrose Finishing School in 1953 already feeling like an outcast: her mother, a glamorous movie star, is dead, and her father is imprisoned under suspicion of being a Communist. All her classmates seem to have it so easy: beautiful Betty is an elegant and popular socialite, while Diane, the richest girl in school, is dangerous and mysterious (and, for some reason, hell-bent on ruining Tiny's life). When a classmate is found dead and Tiny becomes the number one suspect, the situation seems to go from bad to worse. Determined to clear …

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 …

Characterizing The Informativity Of Level Ii Book Data For High Frequency Trading, Logan B. Nielsen

Theses and Dissertations

High Frequency Trading (HFT) algorithms are automated feedback systems interacting with markets to maximize returns on investments. These systems have the potential to read different resolutions of market information at any given time, where Level I information is the minimal information about an equity--essentially its price--and Level II information is the full order book at that time for that equity. This paper presents a study of using Recurrent Neural Network (RNN) models to predict the spread of the DOW Industrial 30 index traded on NASDAQ, using Level I and Level II data as inputs. The results show that Level II …

Utilizing Isothermal Titration Calorimetry To Measure Β-Galactosidase Activity In Dairy Products, Tyler Ronald Jarrard

Theses and Dissertations

The dairy industry uses enzymes to make cheese, alter product flavor, and eliminate lactose. The activities of these enzymes have been measured in clear buffered solutions, but because of the limitations of spectrophotometric methods, enzyme activities have not been measured in opaque or colored dairy products where they are used. Isothermal titration calorimetry (ITC) can be used to determine reaction kinetics in opaque and colored solutions by measuring the heat rate from enzyme-catalyzed reactions as a function of time. This study used ITC to measure β-galactosidase activity in opaque solutions of milk, sweet whey, sweet whey permeate, acid whey, and …

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 …

The Topology And Dynamics Of Surface Diffeomorphisms And Solenoid Embeddings, Xueming Hui

Theses and Dissertations

We study two topics on surface diffeomorphisms, their mapping classes and dynamics. For the mapping classes of a punctured disc, we study the $\ZxZ$ subgroups of the fundamental groups of the corresponding mapping tori. An application is the proof of the fact that a satellite knot with braid pattern is prime. For the mapping classes of the disc minus a Cantor set, we study a special type of reducible mapping class. This has direct application on the embeddings of solenoids in $\mathbb{S}^3$. We also give some examples of other types of mapping classes of the disc minus a Cantor set. …

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 …

Language Modeling Using Image Representations Of Natural Language, Seong Eun Cho

Theses and Dissertations

This thesis presents training of an end-to-end autoencoder model using the transformer, with an encoder that can encode sentences into fixed-length latent vectors and a decoder that can reconstruct the sentences using image representations. Encoding and decoding sentences to and from these image representations are central to the model design. This method allows new sentences to be generated by traversing the Euclidean space, which makes vector arithmetic possible using sentences. Machines excel in dealing with concrete numbers and calculations, but do not possess an innate infrastructure designed to help them understand abstract concepts like natural language. In order for a …

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 …

Large-Scale Testing Of Lightweight Cellular Concrete Backfill For Sliver-Fill Mse Wall Configurations, Meghann Dee Morgan

Theses and Dissertations

Lightweight cellular concrete (LCC) is an aerated or foamed concrete where 25-80% of the concrete matrix consists of air voids. The high volume of air voids reduces the strength but significantly decreases the weight of the material, which has made it an attractive alternative to soil for retaining structure backfills. Though the use of LCC has increased, little research has been performed on the large-scale behavior of retaining structures containing LCC as backfill. This research test attempts to fill knowledge gaps found with regard to the use of LCC in a mechanically stabilized earth (MSE) wall with a trapezoidal or …

Pausing In American English: Documenting Native English Speakers' Pausing Patterns, Ammon Hunt

Theses and Dissertations

The purpose of this study was to examine more deeply the relationship between pause location and duration and its connection to clause and phrase boundaries for native English speakers (NESs). Previous research has shown pauses produced by NESs to be located at clause boundaries (Brown & Miron, 1971; Hawkins, 1971; Tavakoli, 2011), but little empirical work has been done to probe this issue further. For this research, 80 speech samples, 40 male and 40 female, were randomly selected from the International Dialects of English Archive (IDEA) representing different regions in the United States. Oral data from the read-aloud portion of …

The Impact Of Speech Pause On The Perceived Effectiveness And Likability Of A Speaker's Communication, Rebecca Lyman

Theses and Dissertations

The purpose of this study was to examine how length and location of speech pausing affects a listeners' perception of likability and communication effectiveness. Furthermore, the end goal of this study is to understand how to better assess atypical speech pause for persons with aphasia (PWA). Speech samples were collected from two neurotypical speakers over the age of 75. The speech samples were the recorded responses of picture description tasks found in the Western Aphasia Battery (WAB) and the Boston Diagnostic Aphasia Examination (BDAE). These speech samples were then modified to include artificial pauses located both within sentence and between …

The Sino-Soviet Split: A Domestic Ideology Analysis, Caleb Ringger

Sigma: Journal of Political and International Studies

In December 1960, the Peking Review, China’s only English national news magazine, celebrated the “Eternal, Unbreakable Sino-Soviet Friendship” on its front page (Peking Review 1960). The alliance between the world’s largest communist nations certainly seemed ironclad, at least from an outside perspective. But over the next decade, relations between the two allies completely deteriorated, ultimately resulting in bloody confrontation on the Sino-Soviet border, where dozens were killed in violent clashes in March 1969. What accounts for the rapid deterioration in relations between China and the Soviet Union? How could two seemingly close allies turn into enemies so quickly?

The Fourth Amendment In A Digital Age: Defining Boundaries In Law Enforcement Surveillance Of The Home, Josh Hoffman, Jared Xia

Brigham Young University Prelaw Review

As our country enters a new digital age, emerging technologies have increased the ability of law enforcement to monitor American citizens more closely. The tracking of suspects through thermal imaging, video monitoring, and cell phone GPSs are just a few examples of the unlocked potential now available to investigating authorities. When directed at the home, these technologies allow for unprecedented encroachment of our most intimate sphere of daily life. With this accelerating prevalence of technology in surveillance practices comes the need to reassess what boundaries the Fourth Amendment defines for our privacy. This paper explores the application of the Reasonable …

Large Eddy Simulation For Empirical Modeling Of The Wake Of Three Urban Air Mobility Vehicles, Denis-Gabriel Caprace, Andrew Ning

Faculty Publications

Recent advances in urban air mobility have driven the development of many new VTOL concepts. These vehicles often feature original designs departing from the conventional helicopter configuration. Due to their novelty, the characteristics of the super-vortices forming in the wake of such aircraft are unknown. However, these vortices may endanger any other vehicle evolving in their close proximity, owing to potentially large induced velocities. Therefore, improved knowledge about the wakes of VTOL vehicles is needed to guarantee safe urban air mobility operations. In this work, we study the wake of three VTOL aircraft in cruise by means of large eddy …

The Weakening Of The Voting Rights Act: A Proposal For Modernizing Preclearance, Breannan Perez

Brigham Young University Prelaw Review

The Voting Rights Act of 1965 was passed more than 58 years ago. However, despite its attempt to identity and address discrimination, many of its safeguards have been struck down by the Court. In fact, Section 4b aimed to eliminate voting procedures that were discriminatory in effect, but has since been deemed as unconstitutional. Such a ruling has weakened the VRA and has burdened minority voters. This article proposes a modernized preclearance formula that considers states’ voting rights violations and current voting data. Such a proposal is necessary as a disregard of any voter is a threat to the integrity …

Thermal Inactivation Of Salmonella, Escherichia Coli, And Enterococcus Faecium Nrrl B-2354 In Pasta Matrices, Kristi Shannon Gowans

Theses and Dissertations

Limited data are currently available characterizing the thermal resistance of foodborne pathogens in semolina flour and intermediate pasta matrices representative of commercial conditions during mixing, extrusion, and drying. These data are essential to pasta producers seeking to be compliant with federal regulations since Salmonella spp. and Escherichia coli demonstrate survival in wheat flour and dried pasta products. This study investigated the heat resistance of Salmonella, pathogenic E. coli, and E. faecium NRRL B-2354 in raw semolina flour and partially dried pasta intermediates via thermal death time (TDT) studies. This study also assessed the appropriateness of E. faecium NRRL B-2354 as …

Not Acting, Reacting: An Analysis Of Reaction Videos, Reactors, Viewers And Authenticity, Cameron Cox

Theses and Dissertations

The digital age has brought about a new type of YouTuber content creator, the Reactor. Reactors film their supposed first-time reaction to various online videos including trailers, film, television etc. Reactors represent a new performance mode at the intersection of audience member and performer attempting to recreate a lost sense of community in an increasingly digitally mediated world. The act of filming one's reaction calls into question the authenticity of a reaction however, it is this very authenticity that drives Viewers to watch the content made by Reactors. Using reaction videos to the first year of Marvel Studios Disney+ shows …

Losing Control To The Controller: Mmorpg Video Game Addiction And Mediating Roles Of Player Motivations, Abbie Speed

Theses and Dissertations

Using a quantitative survey distributed to regular players of MMORPGs (Massively Multiplayer Online Role-Playing Games) (N = 777), the current study employed a correlation matrix and a parallel mediation model to assess the relationship between play frequency, motivating factors, and video game addiction. The results demonstrated that each of these elements were related to one another to varying degrees (p < .001). The motivating factors identified by Yee (2006) included achievement, immersion, and social interaction, which were tested as mediators and indicated that achievement (a1 = 0.2817, p < 0.001; b1 = 0.4073, p < 0.001) and immersion (a2 = 0.3217, p < 0.001; b2 = 0.2574, p < 0.001) are mediators in the relationship of play frequency and addiction. Social interaction was not significant as a mediator (a3 = 0.3217, p < 0.001; b3 = -0.0235, p = 0.6753). Higher levels of addiction were present for those who were motivated by achievement (rewards) and immersion (storyline/diversion) to play more frequently per week. However, those who were motivated by social interaction to play frequently did not demonstrate a statistically significant relationship with higher levels of addiction. Findings suggest that motivating factors of gameplay may have a mediating effect on the relationship between play frequency and addiction.

Impact Of Applying Visual Design Principles To Boardwork In A Mathematics Classroom, Jennifer Rose Canizales

Theses and Dissertations

Though black boards and white boards have been a fundamental tool in the classroom for over a century, little research has been done on how to best design and present information using these boards. My study takes visual design principles and applies them to boardwork in a mathematics classroom to better organize and clarify the content. This research shows that students notice boardwork, have strong opinions on what makes boardwork good, and that the application of design principles on boards has a significant impact on students and the teacher. Students felt their cognitive load was lightened and that they were …

Meeting Patients Where They Are: A Nurse-Driven Quality Improvement Project To Provide Influenza Vaccinations In The Emergency Department, Stacie Hunsaker, Larry Garrett, Katreena Merrill, Rachelle Rhodes

Faculty Publications

Introduction: Influenza is highly contagious, vaccine-preventable, and may result in significant morbidity and mortality. While vaccination is the primary protection against influenza, vaccination rates remain low. Traditionally, primary care clinics, retail pharmacies, and public health departments offer influenza vaccines. However, offering influenza vaccines in new settings may increase their availability to the public and increase community uptake. This project aimed to add emergency departments as a new influenza vaccine location to increase the number of vaccines distributed during the 2020 to 2021 influenza season.

Methods: Adult patients discharged from 24 emergency departments were included in this pre- post-intervention project. A …

Developing Tools For Introducing Modifications Into The Chicken Genome, Zachary Eldon Olsen

Theses and Dissertations

The chicken is a classic model organism that has provided key insights into embryonic development. Chicken embryos can be directly manipulated and observed during development while retaining the potential to reach adulthood. Despite this benefit, the utility of the chicken in studying development has been limited by the difficulty of introducing genetic changes to the genome. The recent development of cell culture conditions for chicken primordial germ cells (cPGC) has made it feasible to produce transgenic chickens, but there is still a lack of tools for introducing genetic modifications into cPGCs. Recombinase Mediated Cassette Exchange (RMCE) is a technique that …
