Law Enforcement And Traumatic Experiences: A Qualitative Study With Administrators, Tami Jo N. Lieberg

Theses and Dissertations

The culture and work experiences of law enforcement lead to unique workplace trauma. The cumulative and complex trauma commonly faced by law enforcement officers can activate multiple stress-related illnesses, including Post-Traumatic Stress Disorder (PTSD). These illnesses can have high personal costs to the individuals, lead to loss of departmental productivity and effectiveness, and incur higher expenses for taxpayers due to overtime and high turnover rates and potential lawsuits. Research over several decades has identified risk and resiliency factors for officers. One identified risk and resiliency factor is relationship with management. This research study explores how department leaders can assist officers …

Inter-Comparison Of Lunar Reflectance-Based & City Light-Based Aerosol Optical Depth Retrievals Using Viirs Dnb, Aanan Schlief

Theses and Dissertations

Atmospheric aerosols play an important part in maintaining and altering Earth’s radiation balance and often pose a threat to human health. For this reason, atmospheric aerosols have been studied, typically, during daytime hours, through the use of space-borne instruments and ground-based observations. Currently, however, there are no operational nighttime aerosol retrieval methods available from passive-based satellite observations. The Visible Infrared Imaging Radiometer Suite (VIIRS) instrument, which is aboard the Suomi National Polar-Orbiting Partnership (NPP) satellite, includes a Day/Night Band (DNB) that is sensitive to faint light signals at nighttime opening the door for nighttime aerosol studies. Using observations from the …

There are limited quality SBL instruments available that have been validated and tested for reliability in N&D students preparing for clinical practice. This three-article dissertation was to test the reliability of three SBL instruments for N&D students completing the Nutrition Care Process (NCP) during SBL activities. During the first phase of this study, two instruments were developed, and one instrument was modified from another SBL instrument that had been previously validated and used for nursing …

The Application Of Machine Learning Algorithms On Co2 Eor, Chenyu Wu

Theses and Dissertations

CO2 Enhanced Oil Recovery (EOR) is increasingly recognized worldwide for its dual benefits of enhancing oil production and addressing environmental concerns related to greenhouse gas emissions. However, traditional methods for assessing the feasibility of CO2 EOR in a specific field, such as pilot tests and simulations, are often time-consuming and labor-intensive. A critical factor in determining the suitability of a field for CO2 EOR is the CO2 Minimum Miscibility Pressure (MMP), as miscible flooding is more feasible when the reservoir pressure exceeds the CO2 MMP. Traditional determination of CO2 MMP relies heavily on extensive experimentation, which, despite its accuracy, incurs …

This research analyzed 100 Instagram posts of ten Saudi women's public figures using a qualitative methodology to explore how their cultural and gender roles and norms are portrayed and how these portrayals align with Saudi Arabia's Vision 2030 objectives. The findings indicate that these public figures integrate traditional cultural and gender norms with contemporary norms in their online presentations. Traditional attire and familial roles are commonly showcased, underscoring the profoundly ingrained importance of cultural values in alignment with the findings in existing literature. However, there was a noticeable shift towards contemporary portrayals of identity, particularly in professional life, reflecting the …

The Effects Of Juror Characteristics And Case Type On Trans Panic Defense Verdicts, Isabella Noel Coppa

Theses and Dissertations

The trans panic defense is a provocation defense that uses the victim’s transgender identity as justification for the defendant’s violent actions. Previous research has identified juror characteristics that predict support for the gay panic defense (Michalski & Nunez, 2022) and trans panic defense (Michalski et al., 2022), but less is known about whether case type impacts support for the trans panic defense. This study sought to fill this gap by manipulating case type and further exploring juror characteristics that predict greater support of the trans panic defense. This study utilized 188 participants that read crime vignettes featuring transgender or cisgender …

Investigation Of The Regional Innovation System In Rural Region Of New Jersey: A Qualitative Single Case Study, Ketan N. Gandhi

Theses and Dissertations

This single-case study investigated how a partnership between a rural community college in New Jersey and a manufacturer of emerging optics equipment reflected the “regional networked innovation system,” a type of regional innovation system (Asheim & Isaksen, 2002, p.83). The regional innovation system explains a region's development and competitiveness based on a set of actors within a region, developing specific forms of capital derived from social relations, norms, values, and interactions with the community (Doloreux & Parto, 2005).

An Investigation Of The Interactions Of Gradient Coherence And Network Pruning In Neural Networks, Zachary Yauney

Theses and Dissertations

We investigate the coherent gradient hypothesis and show that the coherence measurements are different on real and random data regardless of the network's initialization. We introduce "diffs," an attempt at an element-wise approximation at coherence, and investigate their properties. We study how coherence is affected by increasing the width of simple fully-connected networks. We then prune those fully-connected networks and find that sparse networks outperform dense networks with the same number of nonzero parameters. In addition, we show that it is possible to increase the performance of a sparse network by scaling the size of the dense parent network it …

"I'Ll Stay Where You Want Me To Stay": How Latter-Day Saints Navigate Conflicting Social Values While Remaining Committed To Their Faith, Venice Jardine

Theses and Dissertations

While recent efforts in religious studies have focused on why many Americans seem to be leaving religion entirely, much less is understood about why many others choose to remain committed to their faith--especially when they hold many of the same social values, doubts, or divergent opinions that others cite for leaving. Within a Latter-day Saint context especially, very little research has been done to explore the experiences of those navigating the complexities of competing ethical affordances while remaining committed to their faith. Through ethnographic research in both Salt Lake County and New York City, I document the patterns and processes …

Developing Adult English Language Learners' Fluency And Pronunciation Skills Through Readers Theater, Francisca Constanza Jara Scholz

Theses and Dissertations

This thesis explores the impact of Readers Theater (RT) on the fluency and pronunciation skills of adult English language learners (ELLs) at an intermediate proficiency level. Readers Theater, a technique gaining attention in oral language skills development, involves transforming stories into scripts and performing them orally in a dramatic way. While there is limited empirical research on the extended use of this technique, this study employs a quasiexperimental design with control and treatment groups to evaluate its effectiveness based on temporal fluency measures and level achievement tests. Research has identified three particular temporal fluency measures that correlate with second language …

Physical Activity, Cardiorespiratory Fitness And All-Cause Mortality, Jorin Dane Larsen

Theses and Dissertations

Introduction Both elevated levels of physical activity (PA) and high cardiorespiratory fitness (CRF) are associated with a decreased risk of all-cause mortality. The degree to which an individual's PA level and CRF status interact to influence mortality is not currently fully understood. This study investigated whether PA and CRF were independently related to all-cause mortality, and to what degree PA was associated with improved mortality risk in individuals with low CRF. Methods This is a prospective cohort study using health assessments on individuals gathered between 1975 and 2002. Health assessment data were matched with the National Death Registry to assess …

Sleep It Off? Exploring Sleep Duration And Bedtime Regularity As Potential Protective Moderators Of Early Adversity's Impact On Mental Health In Infancy, Childhood, And Adolescence, Sarah Lindsey Hipwell Kamhout

Theses and Dissertations

Introduction: Adverse Childhood Experiences (ACEs) are known to increase risk of mental health challenges throughout development, and sleep is known to decrease risk of mental health challenges. These have not been studied in tandem in younger cohorts. We investigated whether interactions between sleep duration and sleep regularity would moderate the impact of ACE exposure on risk for the development of mental health disorders. Methods: We conducted secondary cross-sectional analyses on the 2020-2021 waves of the National Survey of Children's Health (NSCH) (n = 92,669). We used logistic and ordinal regression to replicate known main effects of ACEs (total, household, community, …

Songs And Flowers Of The Wasatch: Rhetorical Aesthetics And Latter-Day Saint Women's Poetry, Jolyn D. Brown

Theses and Dissertations

Although the literary quality of women's poetry from the nineteenth century has long been criticized by literary scholars, recent work in reception studies has documented readers' aesthetic experiences with such poetry in order to appreciate its popularity and appeal (Stauffer). Extending this work in literary reception studies, I draw on scholarship in rhetorical studies, specifically rhetorical aesthetics (Clark), to demonstrate how conventional poetic forms and sentimental appeals can be used by marginalized communities to facilitate identification. I examine Songs and Flowers of the Wasatch, a collection of primarily Latter-day Saint women's poetry compiled by Emmaline B. Wells for the 1893 …

Information Literacy In First Year Writing: A Case Study In Instruction, Rebekah A. Jakeman

Theses and Dissertations

With the emergence of the digital age, and the convenience of producing, accessing, and disseminating information, information literacy (IL) has become a prominent topic in higher education, especially in First-Year Writing (FYW) classrooms. Although much research exists about students' struggle to acquire IL dispositions and practices, there is less scholarship about teachers' attitudes towards IL and how they implement IL concepts in the classroom. Rise Smith proposes that to ensure students master IL skills, higher education must ensure that instructors understand, value and apply IL in their teaching. Therefore, my study focuses on instructors' self-efficacy surrounding IL and how it …

Type 2 Diabetes And Marital Quality Declines Moderated By Positive Health Behaviors, Rebekah Case Fankhauser

Theses and Dissertations

Type 2 diabetes affects more than one-quarter of older adults in the United States. Many older adults manage type 2 diabetes (T2D) in the context of marriage, although few studies have acknowledged the effect the illness has on marital quality. The current study examined how the presence of T2D in later life relates to marital quality, and how positive health behaviors--diet, physical activity, and sleep--can moderate the relationship between T2D and marital quality. Data from the 1,200 married older adults in the Life and Family Legacies study were used to estimate moderation models using structural equation modeling in Mplus. Results …

Perceptions Of Tesol Instruction From Varying Feedback Sources, Kylie J. Woffinden

A total of thirty participants from three different participant groups were featured. The three participant groups were composed of students studying at an intensive English lab school, preservice teachers who worked at the lab school, and the mentors and university instructors that guided those preservice teachers. Data collection took place through feedback sessions, during which …

The Effects Of Adverse And Positive Childhood Experiences On Childhood Mental Health And Behavior Problems, Jane Grace Smith

Theses and Dissertations

Adverse childhood experiences (ACEs) are traumatic childhood events with enduring repercussions on child well-being, while positive childhood experiences (PCEs) have been identified in emerging research as capable of offsetting the effects of ACEs. However, little research investigates the combined impact of ACEs and PCEs on child outcomes, which can inform better aid for children exposed to ACEs. The purpose of this study is to address these important gaps in existing ACE literature. Using data from the National Survey of Child Health (NSCH) 2020-2021 (N = 60,809), I examine the individual and interactive effects of ACE, PCEs, and gender on childhood …

Lexical Entrenchment And Cross-Language Activation: A Look Inside The Bilingual Brain, Megan Myers

Theses and Dissertations

We used eye-movement measures to identify the extent to which lexical entrenchment and cross-language activation impact bilingual reading between languages with different alphabets. Specifically, we evaluated first fixation duration, first run dwell time, and total dwell time as predictors of lexical entrenchment and cross-language activation. Our data was collected from English-Russian bilinguals reading Russian material. We found that cross-orthographic neighborhood size has a statistically significant effect on eye movement, and phonetic neighborhood size has no significant effect on any of the eye behaviors analyzed.

Lessening Lacunas: A Genetic Critique And Literary Analysis Of Female Indigenous Characters In Maria Firmina Dos Reis's Gupeva, Xana Furtado

Theses and Dissertations

One year after publishing Úrsula (1860), Maria Firmina dos Reis (Brazil’s first female novelist) published Gupeva, a novella that acts as a continuation of José de Santa Rita Durão’s Caramurú: Poema épico do descubrimento da Bahia (1781). Gupeva depicts the ultimately tragic love between Épica, an indigenous woman, and Gastão, a French sailor. The novella was published twice more during Reis’s lifetime—once in 1863, with minimal orthographic changes, and again in 1865, this time with quite drastic modifications. The editors of Echo da Juventude, where the 1865 version was published, acknowledged these changes by asking readers to be "indulgentes para …

College Students' Perceptions Toward Native And Non-Native Chinese And Spanish Instructors, Xiaoce Ye

Theses and Dissertations

Since the recognition of the distinction between native and non-native language teachers in English Language Teaching (ELT), research has focused on understanding the strengths and weaknesses of both types of instructors. However, limited attention has been given to students' perceptions of native teachers (NSTs) and non-native foreign language teachers (NNSTs) beyond English instruction. This thesis delves into college students' perceptions of native and non-native Chinese and Spanish language instructors in language education, extending beyond the native/non-native English teacher debate. Drawing from existing literature on language teaching, this study contextualizes preferences and biases to provide an understanding of student perceptions. Employing …

Visualizing Intergenerational Kinship: Humor, Grief, And Youth-Led Resurgence In Reservation Dogs, Emily Catherine Huillet

Theses and Dissertations

Audiences have been drawn to Reservation Dogs (2021-2023) because of its life-giving humor and portrayal of contemporary Indigenous realities. Yet the series truly gains its rhetorical power as the creators pair humor with intergenerational kinship to process diverse forms of unresolved grief. In fact, through narrative, the filmmakers map out processing grief and bonding through humor as healthy components of intergenerational kinship, and they position Indigenous youth as leading that balanced approach to kinship. I refer to this artistic rhetorical mapping as visual kinship mapping and I view it as a filmic manifestation of cultural mapping processes described by Leanne …

Conservation And Management Of Greater Sage-Grouse In Strawberry Valley: Quantifying Influences On A Traditional Capture Method And Long-Term Trends In Clutch Size, Janae Radke

Theses and Dissertations

The greater sage-grouse (Centrocercus urophasianus) is a species of conservation concern that has undergone serious declines in the last century. The Strawberry Valley sage grouse population in Utah underwent such a decline from an estimated 3,500 sage grouse in the 1930s to 150 sage grouse in the early 2000s. This decline initiated a long-term conservation and monitoring project in Strawberry Valley with the goal of preserving the sage grouse population. As part of this ongoing conservation project, we investigated factors that impact the success of capturing sage grouse using the night-lighting method (Chapter 1). We found that capture success is …

The Advancement Of Experimental And Computation Tools For The Study Of Molten Salt Chemistry To Facilitate The Extraction Of Strategic Elements In Nuclear Applications, Michael Stoddard

Theses and Dissertations

Nuclear energy presents environmental benefits, yet the challenge of radioactive waste management persists. Advanced solutions, such as Molten Salt Reactors (MSRs), require a more profound understanding of molten salt chemistry. This research aims to develop tools, including a depletion simulator, molten salt electrochemical simulator, and a fluoride-based thermodynamic reference electrode for electrochemical purification. The computationally inexpensive depletion simulator allows for exploration into extraction and processing strategies for molten salt reactors. An illustrative case study on Mo-99 production from MSRs demonstrates the practical application of the theoretical framework, emphasizing the need for optimization in extraction effectiveness and separation difficulty.

Trip - Transformer Interatomic Potential Predicts Realistic Energy Surface Using Physical Bias, Bryce Eric Hedelius

Theses and Dissertations

Accurate interatomic energies and forces enable high-quality molecular dynamics simulations, torsion scans, potential energy surface mapping, and geometry optimization. Machine learning algorithms have enabled rapid estimates of energies and forces with high accuracy. Further development of machine learning algorithms holds promise for producing general potentials that support dozens of atomic species. I present my own Transformer Interatomic Potential (TrIP): a chemically sound potential based on the SE(3)-Transformer. TrIP's species-agnostic architecture--using continuous atomic representation and homogenous graph convolutions--encourages parameter sharing between atomic species for more general representations of chemical environments, keeps a reasonable number of parameters, serves as a form of …

Arthur Is Only Sleeping: A Reawakening Of John Steinbeck's The Acts Of King Arthur And His Noble Knights, Caroline J. Raines

Theses and Dissertations

John Steinbeck, known for his descriptions of the American West, maintained a fascination with the Arthurian legend throughout his life and literary career. Through comparative analysis of Cup of Gold, Tortilla Flat, and The Acts of King Arthur and His Noble Knights, we can see Steinbeck's recurring interest in the Arthurian legend which is often overlooked by scholars. Steinbeck's initial interest in strict translation which evolved into adaptation over the course of his work on The Acts shows his developing interest in Arthurian themes which he enhanced with his own creative abilities as a world-renowned author. By highlighting the gap …
