Racial Differences And Lived Experiences: Civil Rights Experiences And A Private, Religious, Predominantly White Institution, Anthony Brandon Bates
Theses and Dissertations
Purpose: This article explores the expressed thoughts and feelings of 24 research participants who processed and articulated their lived experiences. They each attended the same private, religious, historically, and predominantly White institution and participated in a three-credit course that covered the history of the Civil Rights Movement of the 1950s and '60s, which culminated in an experience in Georgia and Alabama (Civil Rights experience). Methods: In this phenomenological study, the research participants all participated in a semi-structured interview with the same bank of questions. The questions were designed to examine their lived experiences, within the context of participating in the …
Marital Stability In Newlywed Remarried Couple Relationships: Positive Communication And Marital Interactions In Shared Moments Or Activities, Colette Hickman-Evans
Marital Stability In Newlywed Remarried Couple Relationships: Positive Communication And Marital Interactions In Shared Moments Or Activities, Colette Hickman-Evans
Theses and Dissertations
Remarriages are more structurally diverse, last less time, are more vulnerable, and at greater risk for divorce than first marriages. The newlywed stage of marriage is a critical time when relationship patterns are established or reinforced that can impact a relationship for years to come, yet very few studies have examined remarried relationships in the newlywed stage. This study examined the association between marital interaction, positive communication, and marital instability in 348 newlywed remarried couple participants from a nationally representative sample. Using structural equation modeling (SEM) and actor-partner interdependence model with mediation (APIMeM), the findings indicated that positive communication was …

Refill Friction Stir Fastener Repair In Aa7050-T7451, Andrew John Curtis
Theses and Dissertations
The majority of Refill Friction Stir Spot Welding (RFSSW) is used to join two materials together oriented in a lap joint configuration. In this study, RFSSW was investigated and tested using an unconventional configuration setup, a hole/plug insertion approach. RFSSW was tested as a means of repairing a cracked rivet hole due to excessive use conditions. This was done by inserting a plug into a hole and using the RFSSW process to bond the plug to the base material. Machine and tool limits were investigated to determine if a refilled plug repair was possible and if complete mixing between plug/hole …

Theses and Dissertations
The present study looked at the effects of a self-regulatory goal setting framework (WOOP) implemented in writing classes that were developed by Oettingen (2018) using Mental Contrasting and Implementation Intentions (MCII). The study examined English learners' development on self-reported self-regulation and proficiency levels in an Intensive English Program (IEP) in the United States over the course of two 14-week semesters. A total of 238 English Language Learners participated in the study and took the Short Self-Regulation Questionnaire (SSRQ) where the scores were analyzed to determine development over time. The analysis showed no statistically significant differences. However, experimental group participants' self-reported …
Pivotal Response Treatment To Decrease Challenging Behavior And Increase Functional Communication In Preschool Children With Developmental Delays, Kalie Alexandra Gilmour
Pivotal Response Treatment To Decrease Challenging Behavior And Increase Functional Communication In Preschool Children With Developmental Delays, Kalie Alexandra Gilmour
Theses and Dissertations
After a review of the literature on Pivotal Response Treatment (PRT) in young children with developmental delays, less was known on its effects on challenging behavior and functional communication in preschool age children receiving services in a traditional public school. A multiple baseline design across three participants was used to evaluate the effects of PRT on the functional communication of three preschool students with developmental delays. Based on a functional analysis, we also observed the effects of PRT on challenging behavior. A visual analysis of the data revealed a functional relation between PRT and functional communication and provided promising evidence …
Quantifying Speech Pause Durations In Typical English Speakers, John Hoffer
Quantifying Speech Pause Durations In Typical English Speakers, John Hoffer
Theses and Dissertations
This study examines filled and unfilled pause durations between utterances in the speech of 60 people with no language disorder. It also evaluates the proportions of different pause lengths, examines the location of pauses within an isolated speech sample, and compares speech pause in male speakers and female speakers. Using speech samples gathered from a picture description task, Praat acoustic analysis software was used to segment C-units and measure pause duration between utterances (Boersma & Weenink, 2022; Öktem et al., 2021). Descriptive statistics were used to analyze these data, including pause duration mean and standard deviations. Pause mean durations ranged …
Accounting For Oral Language Skills In Children With Dyslexia: A Systematic Review Of The Literature, Natalie Kay Olsen Miller
Accounting For Oral Language Skills In Children With Dyslexia: A Systematic Review Of The Literature, Natalie Kay Olsen Miller
Theses and Dissertations
Purpose: In the present study, we conducted a systematic review to determine whether studies involving children with dyslexia include the assessment of oral language skills in their assessment batteries across various professional disciplines. Overlooking assessment of oral language in children with dyslexia may result in the misinterpretation of research findings and applications to children who present with both dyslexia and Developmental Language Disorder (DLD) or experience secondary oral language deficits. Method: According to the Preferred Reporting Items for Systematic Reviews and MetaAnalyses (PRISMA) guidelines, we searched the Elsevier Scopus database and obtained and analyzed 764 articles, up to 40 articles …
Design, Synthesis And Immunological Testing Of Minimal Oligosaccharide Epitopes For Glycoconjugate Vaccines Targeting Capsular Polysaccharides Of Serotypes 3, 4, 7f And 9v Of Streptococcus Pneumoniae, Seth A. Taylor
Theses and Dissertations
The rise in antibiotic resistant strains of bacteria has led to the need for new methods of combatting bacterial infection. Since the surfaces of bacteria are covered in uniquely patterned capsular polysaccharides, vaccines targeting these polysaccharides have become a popular field of research for protection against pathogenic bacteria. Though licensed polysaccharide vaccines are commercially available, they lack the efficiency to protect patients that are immunocompromised or at high risk because they elicit T cell independent immune responses, resulting in low-affinity antibodies. To elicit a T cell dependent response and thereby recruit B cells that produce high-affinity antibodies, a vaccine was …
Investigating The Use Of Translational Methods To Characterize Therapeutic Interventions In Models Of Pulmonary Disease, Ashley Rae Chang
Investigating The Use Of Translational Methods To Characterize Therapeutic Interventions In Models Of Pulmonary Disease, Ashley Rae Chang
Theses and Dissertations
Idiopathic Pulmonary Fibrosis (IPF) is an interstitial lung disease with no known cause or cure. IPF has an incidence of 75/1,000,000 of the population, predominately in men over the age of 60. This relatively rare disease develops in a chronic and progressive way, ultimately leading to death within two to five years of diagnosis. Our use of translatable methodologies in the bleomycin mouse model of IPF led to the novel identification of the similarities between the average percent loss of lung function in previous human clinical trials to that of our mouse model data. There is no treatment for IPF …
Developing Microfluidic Devices For Biomolecule Analysis, Jacob Brent Nielsen
Developing Microfluidic Devices For Biomolecule Analysis, Jacob Brent Nielsen
Theses and Dissertations
Microfluidics can take laboratory processes and miniaturize them, which led to the term lab-on-a-chip. Microfluidic devices are fabricated with a variety of materials and methods, each offering distinct advantages for bioanalysis. This dissertation describes two methods to create these devices, with the use of four different materials to achieve different assay needs. In the first application in this dissertation, hot-embossed cyclic olefin copolymer was used to create microdevices to electrophoretically separate seven preterm birth biomarkers. One biomarker, thrombin-antithrombin III, cannot be purchased commercially so I developed methods for its assembly in the lab. Dot blots and mass spectrometry were used …
Context Dependence Of Non-Covalent Interactions Among Amino-Acid Side Chains Along The Solvent-Exposed Surface Of Coiled Coils, Kimberlee Larsen Stern
Context Dependence Of Non-Covalent Interactions Among Amino-Acid Side Chains Along The Solvent-Exposed Surface Of Coiled Coils, Kimberlee Larsen Stern
Theses and Dissertations
Coiled coils are a well-known protein structure prevalent in eukaryotic function, synthetic applications, and de novo protein design. Coiled-coil folding is often described using heptad repeat positions labeled abcdefg where a and d positions occupy the interface between the coils, e and g positions flank the interface, and the b, c, and f positions face the solvent-exposed surface. The a, d, e, and g positions have been extensively studied in the coiled-coil literature. There is a lack of investigation on the impact of the b, c, and f positions on coiled-coil folding. Chapter 1 is an introduction to the heptad …
Navigating Molecular Complexity: A Multidimensional Approach Utilizing Computational Chemistry, Jacob Andrew Parkman
Navigating Molecular Complexity: A Multidimensional Approach Utilizing Computational Chemistry, Jacob Andrew Parkman
Theses and Dissertations
Preparing molecular coordinate files for molecular dynamics (MD) simulations can be a very time-consuming process. Herein we present the development of a user-friendly program that drastically reduces the time required to prepare these molecular coordinate files for MD software packages such as AmberTools. Our program, known as charge atomtype naming (CAN), creates and uses a library of structures such as amino acid monomers to update the charge, atom type, and name of atoms in any molecular structure (mol2) file. We demonstrate the utility of this new program by rapidly preparing structural files for MD simulations for polypeptides ranging from small …

Latter-Day Saint Women And Leadership In Higher Education: An Intrinsic Case Study, Elizabeth J. Darger
Theses and Dissertations
There are few women in the highest levels of leadership in most industries, including higher education. This intrinsic case study provides insight into the leadership journeys of 15 female leaders at Brigham Young University, which is sponsored by The Church of Jesus Christ of Latter-day Saints. Four prevalent themes emerged about their leadership journeys. First, a leadership role was not part of the participant's life plan. The remaining three themes related to acceptance of a leadership role. Participants reported feeling nudged to consider a leadership role, feeling a sense of relational responsibility in accepting a leadership role, and receiving a …
Soft Contact Lens Tear Film Proteomics For Clinical Diagnostic Biomarker Discovery, Robert Kimball Roden
Soft Contact Lens Tear Film Proteomics For Clinical Diagnostic Biomarker Discovery, Robert Kimball Roden
Theses and Dissertations
Human tear film is an accessible biospecimen rich with useful biological information. As tear protein biomarkers for both ocular and systemic diseases have been identified in tears, efforts are being made to create point-of-care tests useful for clinical diagnoses. However, there are significant obstacles to tear diagnostics, including inadequate sampling methods and biomarkers with insufficient sensitivity and specificity. Furthermore, tear film diagnostics are particularly challenging for dry eye disease (DED) patients, where low tear volume makes sampling more difficult and the multifactorial nature of DED makes identifying the exact pathological subtype very complex. As soft contact lenses (SCLs) are designed …
Cesium Voltilization In Lif-Bef2: Predicting Release In The Event Of Fhr Fuel Failure, Johnny Hedrick Williams
Cesium Voltilization In Lif-Bef2: Predicting Release In The Event Of Fhr Fuel Failure, Johnny Hedrick Williams
Theses and Dissertations
This work demonstrates how ICP-MS can be employed to evaluate cesium volatilization from LiF-BeF2 (Flibe) salt with ab initio molecular dynamics studies used as corroborating data to better understand cesium behavior. Using mixtures of Flibe with 2 mol% CsF, it was found that cesium was stable within the salt melt at temperatures between 500-650°C over a time span of 8 hours. At 800°C, cesium vaporized from the salt at a rate of 0.83% / hr with a mass flux of 0.0023 g Cs / cm2hr. The atomistic modeling results show poor solvation of Cs at 500°C and 800°C, with stability …
The Performative History Of Tomboys In Anglophone Literature Prior To Little Women, Kimber Palmer
The Performative History Of Tomboys In Anglophone Literature Prior To Little Women, Kimber Palmer
Theses and Dissertations
This paper examines the expansive history of literary tomboys in the century preceding Louisa May Alcott's Little Women (1868). Applying concepts from gender performativity theory, it explores earlier and previously overlooked portrayals of tomboys (or, alternatively, "hoydens" or "romps"), especially in Richard Brinsley Sheridan's A Trip to Scarborough (1777), Isaac Bickerstaffe's The Romp; A Comic Opera in Two Acts (1786), Mary Wollstonecraft's A Vindication of the Rights of Woman (1792), Jane Austen's Northanger Abbey (1817), and E.D.E.N. Southworth's The Hidden Hand (1859). Because the tomboy phenomenon emphasizes that gender roles must be learned and can be resisted, tomboy characters are …
Gratitude Training For Promoting Subjective Well-Being: A Randomized Controlled Trial Comparing Journaling To A Personalized Menu Approach, Conner Lee Deichman
Gratitude Training For Promoting Subjective Well-Being: A Randomized Controlled Trial Comparing Journaling To A Personalized Menu Approach, Conner Lee Deichman
Theses and Dissertations
Research suggests a link between gratitude and subjective well-being exists. Research on gratitude practices have shown to increase gratitude, subjective well-being, and other related outcomes. However, the efficacy of gratitude practices may be limited by the rote application of the gold standard gratitude practice--the gratitude journal. Such findings suggest that a more comprehensive, adaptable, and flexible gratitude practice may be needed. This study examined the efficacy of the My Best Self 101 (MBS101) gratitude module: an online gratitude resource that provides psychoeducation about gratitude along with a menu of empirically based gratitude practices. Using a randomized controlled design method, this …
Family Of Origin Stress, Posttraumatic Stress Symptoms, And Resource Loss For Couples During Covid-19: A Longitudinal Analysis, Betsy Hughes Barrow
Family Of Origin Stress, Posttraumatic Stress Symptoms, And Resource Loss For Couples During Covid-19: A Longitudinal Analysis, Betsy Hughes Barrow
Theses and Dissertations
The pandemic affected daily life on an unprecedented global scale resulting in the need for adaptation and flexibility to cope with ongoing stress, uncertainty, and loss that may affect couple relationships. Understanding resource loss in the context of mass stress events is critical because resource loss has been defined as the primary agent of stress (Hobfoll, 1989). As such, it is important to understand what factors may have shaped the degree of resource loss incurred during the pandemic. Extant research implies that considering early life adversity may be useful to explore as it may be a form of resource loss …

Three species, Acarospora coloradiana, A. peltastica, and A. utahensis are not treated as synonyms of A. strigata, a South American endemic. Thirty-four species of Acarosporaceae are reported from the Chihuahuan Desert in southern New Mexico. Fifty-six species of Acarosporaceae are reported from New Mexico. It is estimated that 416 species of described Acarosporales occur worldwide, most in need of revisions. …
Exploration Of The Impact Of Gender-Affirming Care And Social Support On Executive Functioning And Mental Health In Gender-Diverse Autistic And Non-Autistic Adults, Karys Michaela Normansell-Mossa
Exploration Of The Impact Of Gender-Affirming Care And Social Support On Executive Functioning And Mental Health In Gender-Diverse Autistic And Non-Autistic Adults, Karys Michaela Normansell-Mossa
Theses and Dissertations
Between 4.8% and 26% of adults presenting to gender dysphoria clinics have an autism diagnosis. Both autistic people and gender-diverse people have higher rates of mental health conditions including anxiety and depression and more difficulties with executive functioning, all of which impact quality of life. Some work suggests that gender affirmation leads to better mental health outcomes, including better executive functioning, but this has not been studied directly in autistic adults who identify as gender-diverse or transgender. As such, we elected to explore the relationships among these variables at this intersection of gender diversity and autism. In a sample of …
Securing Wireless Communication Via Information-Theoretic Approaches: Innovative Schemes And Code Design Techniques, Morteza Shoushtari
Securing Wireless Communication Via Information-Theoretic Approaches: Innovative Schemes And Code Design Techniques, Morteza Shoushtari
Theses and Dissertations
Historically, wireless communication security solutions have heavily relied on computational methods, such as cryptographic algorithms implemented in the upper layers of the network stack. Although these methods have been effective, they may not always be sufficient to address all security threats. An alternative approach for achieving secure communication is the physical layer security approach, which utilizes the physical properties of the communication channel through appropriate coding and signal processing. The goal of this Ph.D. dissertation is to leverage the foundations of information-theoretic security to develop innovative and secure schemes, as well as code design techniques, that can enhance security and …
Exploring Surface Silanization And Characterization Of Thin Films: From Surface Passivation To Microstructural Characterization Of Porous Silicon/Silica, And Exploratory Data Analysis Of X-Ray Photoelectron Spectroscopy Images, Behnam Moeini
Theses and Dissertations
Surface chemistry plays a key role in science and technology because materials interact with their environments through their surfaces. Understanding surface chemistry can help alter/improve the properties of materials. However, surface characterization and modification often require multiple characterization and synthesis techniques. Silicon/silica-based materials are technologically important, so studying their surface properties can enable future advancements. In this dissertation, I explore surface modification and characterization of different types of Si/SiO2 thin films, including silicon wafers, fused silica capillary columns, and oblique angle sputtered Si/SiO2 thin films. In Chapters 2-5, I first present a method to rapidly silanize silica surfaces using a …
Visions Of Mary: Patria As The New Mestiza Madonna In Alvarez's In The Time Of The Butterflies, Mila Argueta
Visions Of Mary: Patria As The New Mestiza Madonna In Alvarez's In The Time Of The Butterflies, Mila Argueta
Theses and Dissertations
Alvarez’s In the Time of the Butterflies is a fictional depiction of three sisters who are lauded for their role in ending the supremacist, womanizing, and terror-inspiring reign of Trujillo. While, one character, Patria, seems to represent the traditional, and at times cloistered, life of a Dominican wife and mother (reflecting the Malinche and sufrida archetypes), the text also shows her transformation into one of the most vital figureheads of the revolution. I find that when she joins the revolution, she comes as a transformed Marian-figure. Unlike Ibez Gomez Vega and other feminist scholars who have categorized Patria as one …
Mental Health Literacy In Polynesian Native Hawaiians And Other Pacific Islanders: A Pilot Cross-Sectional Study, Kealoha Sarah Reiko Snow
Mental Health Literacy In Polynesian Native Hawaiians And Other Pacific Islanders: A Pilot Cross-Sectional Study, Kealoha Sarah Reiko Snow
Theses and Dissertations
Background: High prevalence of mental health problems and underutilization of mental health treatment are more severe among the Native Hawaiian and Other Pacific Islander (NHPI) population and remain misunderstood and understudied. Examining mental health literacy (MHL)–the knowledge and beliefs about mental disorders which aid their recognition, management, or prevention–has been shown to identify barriers to seeking and receiving care. Objectives: This study aimed to assess the level of MHL in Polynesian NHPIs and identify associated demographic variables. Methods: Data for this pilot cross-sectional study were collected from 298 US Polynesians via an online questionnaire of the Mental Health Literacy Scale …
Silver Sagebrush (Artemisia Cana) Survival And Regrowth After Fire In The Mixed Grass Prairie, Marcus A. Comfort, Eric G. Lamb
Silver Sagebrush (Artemisia Cana) Survival And Regrowth After Fire In The Mixed Grass Prairie, Marcus A. Comfort, Eric G. Lamb
Western North American Naturalist
Silver sagebrush (Artemisia cana) is a low shrub species that is common in northern mixed grass prairies and that provides important wildlife habitat. Silver sagebrush habitat has historically experienced frequent wildfires, but postsettlement fire control efforts have reduced fire frequencies. The effects of fire on silver sagebrush growth and regeneration are not clearly understood; this study examined the effects of fire on silver sagebrush regeneration by evaluating postfire plant size and distribution data from one season. Sites were located in the northern mixed prairie in Saskatchewan, Canada, and included pastures where the plant community was recovering from both …
Conspecific Tolerance In A Solitary Small Carnivore, The Pacific Marten, Matthew S. Delheimer, Marie E. Martin, Katie M. Moriarty
Conspecific Tolerance In A Solitary Small Carnivore, The Pacific Marten, Matthew S. Delheimer, Marie E. Martin, Katie M. Moriarty
Western North American Naturalist
Holarctic martens (genus Martes) are small carnivores that are considered functionally solitary, with both resource scarcity and martens’ inability to store energetic reserves posited as precluding social behavior. Interactions between martens are expected to be largely agonistic with the exception of mating and rearing of kits by adult females. Nonetheless, we documented multiple instances of conspecific tolerance by Pacific martens (M. caurina) during long-term monitoring of radio-marked animals in 2 study populations. Observations from radio-tracking and remotely triggered camera trap photographs suggested that pairs of martens traveled, foraged, and rested together. Presumed marten associations occurred both inter- …
Nest Success By A Female Black-Chinned Hummingbird (Archilochus Alexandri) With Male-Like Plumage, Cooper M. Farr, John Middleton
Nest Success By A Female Black-Chinned Hummingbird (Archilochus Alexandri) With Male-Like Plumage, Cooper M. Farr, John Middleton
Western North American Naturalist
Female-limited polymorphism, a phenomenon in which female animals can exhibit male-like coloration, is known to occur in approximately 25% of hummingbird species, but it has not previously been recognized in Black-chinned Hummingbirds (Archilochus alexandri). Between May and July 2021, we documented a Black-chinned Hummingbird with male plumage features that built a nest, incubated eggs, and successfully fledged 2 chicks in Salt Lake City, Utah. The bird’s gorget feathers, including the chin and upper throat, were predominantly dark with a small number of white feathers interspersed. Because the bird participated in nest building, presumed egg production, and incubation—behaviors not …
