Predictors of Perfectionistic Tendencies in Sport among Undergraduate Kinesiology Students
Authors:   , Boyd Christopher A.
Published: February 2025

The purpose of this study was to examine current kinesiology students' athletic identity, identity foreclosure, perceived task value in sport, and perfectionism. An online survey was distributed via email to current kinesiology students. The survey contained questions regarding demographic information and items from the Athletic Identity Measurement Scale, Extended Objective Measure of Ego Identity Status, Perceived Task Value in Sport, Sport Multidimensional Perfectionism Scale-2, and Multidimensional Inventory of Perfectionism in Sport. Results of the Pearson moment correlations indicated that the higher the athletic identity, the higher the subjective task value, identity foreclosure, perfectionistic strivings, and perfectionistic concerns. Multiple regression analyses were performed to further examine the predictive power of athletic identity, subjective task value, and identity foreclosure for perfectionistic strivings and perfectionistic concerns. Results indicated that athletic identity and subjective task value were significant predictors of perfectionistic strivings. Results also showed that athletic identity and identity foreclosure were significant predictors of perfectionistic concerns. Future research should replicate the study using participants from different geographical regions. Furthermore, future research should consider a longitudinal and qualitative study to investigate the development of subjective task value in sport.
Psalms, Hymns, and Commercial Songs: Tradition and Innovation in James Lyon's "Urania"
Authors:   , La Spata Adam
Published: February 2025

This dissertation asserts the value of James Lyon's Urania to the field of American music history as a vital contribution to the development of music in the British colonies prior to the War for Independence. While previous scholarship acknowledges Urania's importance as the first publication in America to contain music by a native-born composer, this study argues that its subscription list and selection of anthems (both of which were new to the field of American music publishing) contribute to the status this compilation is due. The confluence of the English chapel tradition and American singing school tradition contributes to the theological universality and accessibility of its twelve anthems. An introductory chapter discusses the secondary literature upon which this study is based - notably that of Oscar Sonneck and Richard Crawford - and posits applications for the idea presented herein beyond the field of musicology. Chapter 2 provides biographical information on James Lyon and contextualizes Urania within the broader framework of the English chapel tradition and the American singing-school tradition. Chapter 3 discusses the marketability of music in colonial America and explores the biographies of the subscribers to Urania using modern databases. Chapter 4 concerns the confluence of music and sacred text by placing Urania as a spiritual and cultural descendant of the theological universality preached during the Great Awakening. It concludes with an analysis of the anthems, taking into account both text and music. Chapter 5 concludes the study by showing how Urania affected music in the generations after its publication. My dissertation concludes with four appendices. Appendix A is an annotated list of Lyon's subscribers. Appendix B parses out basic information on the anthems, notably the texts. Appendices C and D provide critical notes and editions of the anthems, respectively.
Fire Eater in the Borderlands: The Political Life of Guy Morrison Bryan, 1847-1891
Authors:   , Kelley Ariel Leticia
Published: February 2025

From 1847 to 1891, Guy Morrison Bryan was a prominent Texas politician who influenced many of the policies and events that shaped the state. Raised in his Uncle Stephen F. Austin's shadow, he was a Texas nationalist who felt responsible for promoting the interests of his state, its earliest settlers, and his family. During his nineteen years in the Texas Legislature and two years in the United States House of Representatives, he safeguarded land grants, supported internal improvements and education, and challenged northern hostility towards slavery. Convinced that abolitionists would stop at nothing to destroy the institution and Texas, he led his state's walkout of the National Democratic Convention in 1860 and became a leading proponet of secession. During the Civil War, he served as a staff officer, and his ability to mediate conflicts between local and national leaders propped up the isolated Confederate Trans-Mississippi Department. Finally as Speaker of the House, he helped oust Governor Edmund J. Davis in 1874 and "redeem" the state from Republican rule before convincing President Rutherford B. Hayes to adopt a conciliatory policy towards Texas and the South. Despite the tremendous influence Bryan wielded, scholars have largely ignored his contributions. This dissertation establishes his significance, uses his willingness to transfer national allegiances to consider nationalism--whether Texan, American, or Confederate--in the United States-Mexico Borderlands, and sheds light on neglected subjects like the role of staff officers in the Civil War.
An Investigation of the Influence of Attributional Complexity, Intolerance, Optimism, and Experiential Avoidance on Personal Psychological Distress
Authors:   , Ergüder Leyla
Published: February 2025

The purpose of this study was to investigate the impact of low attributional complexity, intolerance, optimism, and experiential avoidance (EA) on psychological distress (stress, anxiety, and depression); specifically, the mediating role of EA in these relationships was examined. Structural equation modeling (SEM) was utilized to test the hypothesized model. The overall model accounted for 62% of the variance in psychological distress. The direct negative effect of intolerance on psychological distress and the mediator effect of EA on the relationship between optimism and psychological distress were found. These results and their implications, along with study limitations and future directions are discussed.
Association of Trainee Psychotherapist Competency and Client Outcomes
Authors:   , Dziurzynski Kristan
Published: February 2025

Client outcomes in psychology training clinics have been shown to be generally worse than other outpatient settings. Although this finding has been repeatedly demonstrated, no consensus of cause has emerged in the literature. One possible explanation of such findings may relate to psychotherapist effects, a historically neglected variable that has received increased attention in more recent literature. Among psychotherapist effects researched, competency has emerged as a compelling factor worthy of more research. Given that most growth in competence occurs during graduate training, investigating the relationship between competency and client outcome offers great potential benefit for informing optimal training, nature of client symptom improvement, and a more accurate depiction of differences in psychotherapist effects across training and non-training settings. The purpose of this study was to explore the trajectory of competence development during doctoral training in health services psychology and to investigate the association of trainee competency to the psychotherapy outcomes evidenced by their clients. Practicum evaluations of 36 trainees and outcome data (using the Outcome Questionnaire-45.2) from 244 adult clients were included in analyses. Results of the study suggest there is a positive relationship between cumulative semesters of training and competency scores (rs[118]= .34, p < .001). Notably, there was no significant difference in psychotherapy outcome between low and high trainee competence. The results of the current study, relevant literature and limitations are discussed. Suggestions for future research are proposed.
Mass Spectrometry Guided Development of a Controlled Release Nanotransfersome Transdermal Drug Delivery System
Authors:   , Kiselak Thomas Dieter
Published: February 2025

Poor medical adherence attributed to patient compliance has impacted the medical community, at times, in a deleterious fashion. To combat this, the medical community has attempted to provide therapeutics in the form of absorption enhancing techniques. To improve the absorption rate techniques such as drug encapsulation using proteins, liposomes, or nanotransfersomes have been developed using mass spectrometry. These techniques, have aided in the enhanced absorption of analytes with low bioavailability, including curcumin, simvastatin, and lysozyme. Specifically, mass spectrometry allows for the development and monitoring of nanotransfersome encapsulated analytes and the permeation across the dermal membrane. This transdermal delivery would eliminate the problems encountered during first pass metabolism, while allowing for higher concentrations of analyte to be maintained in the blood serum. This can be coupled to a thermosensitive gelatin that provides for a dose control mechanism to be accomplished, allowing multiple doses to be delivered using one transdermal patch system. The novel delivery system developed using mass spectrometry, allows the analyte to be delivered into the circulatory system at a controlled dosage, via transdermal absorption. This system will aid in eliminating problems associated with patient compliance, as the patient is no longer reliant on memory to self-dose. Further, this system mitigates the concerns of patients overdosing with more potent pharmaceuticals.
The Political Economy of Retailing Sustainable Food: Green Consumerism and Sustainability
Authors:   , Toofan Megan H.
Published: February 2025

In recent decades, the global impacts of unsustainable consumption and production patterns have become a leading topic of sustainability, and more recently, climate action discourse. At the policy level, green consumerism – an element of green capitalism – has been positioned as the pathway to more sustainable consumption and production (SCP) practices. Within this model, eco-labeling schemes are used to communicate various sustainability attributes, or conditions of production, to the consumer. This study set out to investigate whether SCP is achievable through green consumerism using a two-part case study that centers around the egg industry and specific hen welfare standards. The case study examines the effectiveness of egg eco-labeling schemes and related statements and images placed on egg packaging in informing consumers' purchasing decisions. It also examines the impacts of green consumerism on organic egg production in the presence of strong consumer demand for enhanced hen welfare standards. The results of the case study demonstrate that in the egg industry, green consumerism is not highly effective because consumers' purchasing decisions are often informed by vague and misleading information about conditions of production. Moreover, the presence of strong consumer demand has not resulted in enhanced hen welfare standards in organic production. In interpreting these findings through the lens of David Harvey's theory of the spatial fix, I argue that the true role of green consumerism is to facilitate a spatial fix to resolve the chronic crisis of overaccumulation in the conventional egg industry. Furthermore, that the limitations and contradictions within green consumerism (e.g. vague or insignificant eco-label claims) aid in removing the barrier of capital fixity so that the spatial fix can occur.
Application of Novel Microporous Polyolefin Silica-Based Substrate in Paper Spray Mass Spectrometry (PS-MS)
Authors:   , Weligamage De Silva Imesha
Published: February 2025

This study addressed five key applications of paper spray mass spectrometry (PS-MS): (i) comparative analysis of the microporous substrate with the cellulose-based substrate in drug detection; (ii) detection of more than 190 fentanyl analogs with their fragmentation pattern can be implemented in the future reference for quicker, accurate and sensitive determination; (iii) exploring sweat in a fingerprint to be considered an alternate method to recognize non-invasive markers of metabolites, lipids, narcotics, and explosive residues that can be used in forensic testing applications; (iv) extending and improving better, cost-effective and quick real-time monitoring of the diseased stage using biofluid samples to obtain vastly different lipid information in viral infection such as COVID-19; and (v) mass spectral detection in chemical warfare agent (CWA) stimulant gas exposure with microporous structure absorbency capabilities in air quality monitoring. This novel synthetic material is known as Teslin® (PPG Industries), consisting of a microporous polyolefin single-layered silica matrix, can be used for precise, sensitive, selective, and rapid sample analysis with PS-MS. The Teslin® substrate provided longer activation time for samples and an active signal with a higher concentration of ion formation and mobility compared to cellulose-based papers. Direct analysis of multiple samples showed that, besides being more sensitive to the study and highly efficient with less sample size and spray solvent needed, Teslin® had less interaction with paper source molecules. For less than 60 seconds of processing time, PS-MS can be used as a rapid detection tool, with limited sample preparation requiring less than one microgram of the sample. Overall, the data in this analysis indicate the capacity of the PS-MS as an alternative approach for direct chemical analysis in many applications. Specifically, the waterproof and microporosity characteristics of Teslin® have proven its usefulness in detecting a variety of chemical components in liquid, solid, and gaseous phases without requiring any chemical treatment or substrate alteration.
Testing the Narrative of Prussian Decline: 1778-1806
Authors:   , Soefje Ethan K
Published: February 2025

The story of Prussia's defeat at the Battles of Jena and Auerstedt and subsequent reform has dominated the historiography of Napoleonic Prussia. While Napoleon has received the vast majority of historical attention, those who have written on Prussia have focused on the Prussian reform movement or the Prussian army's campaigns against Napoleon. These historians present the Prussian army before 1807 as an ossified relic, a hopelessly backward and rigid army commanded by a series of septuagenarians. Apart from the 1806 campaign, these scholars scarcely address the field operations of the Prussian army during the French Wars (1792-1801). This thesis seeks to prove that the Prussian army during the War of the Bavarian Succession and the War of the First Coalition was still an effective fighting force by examining the field operation of the Prussian army from 1778-1793 and the reactions of Prussian thinkers to it. The history of the Prussian army from 1778-1806 challenges the narrative of the army as a force in decline. The Prussian army struggled in the War of the Bavarian Succession, and the war revealed two of its weaknesses, the lack of light troops and an uncoordinated strategic approach. However, many of the problems of the war were failures of Fredrick and Henry as generals rather than the army as a whole. The army's performance during the War of the First Coalition against the French proved that it was a highly effective force and able to win even when significantly outnumbered. The existence of the reform movement following the war of the First Coalition and the implementation of some changes demonstrated that the army was far from dormant and its officers still sought ways improve it. While the army did not enjoy commanders of the caliber of Frederick the Great in his prime, before 1806 it retained the discipline and effectiveness in battle it displayed under Fredrick.
A Study of Conwy and Caernarvon Castles in Wales: A Colonial Reexamination of the Conquest of Wales, 1284
Authors:   , Liberty Samuel Joseph
Published: February 2025

King Edward I of England's castle building program in Wales from 1282 to 1295 provides a unique event that can be studied in further detail. Edward's castle building program turns the conquest of Wales into an early example of what future English colonization would become. By examining the building of Conwy and Caernarvon in Wales and the accompanying social programs we are better able to understand how the English viewed conquest and colonization. The conquest spent approximately £35,000 on the building of the castles of Conwy and Caernarvon, a colossal sum for the time. The reallocation of resources from England into Wales provide important similarities to later colonial endeavors, especially in the large application of manpower to build successful colonies. Another similarity becomes the split between the use of local raw resources such as the stone and timber combined with the need for manufactured goods brought from England. The social changes also had a major impact. The construction of Edward's castles Conwy and Caernarvon replaced iconic locations of Welsh power. The accompanying Statute of Wales (1284) changed the Welsh legal landscape and forced the English legal system on the Welsh. By replacing Welsh locations of power and instituting legal reform England made it possible for its colonists to safely enter northern Wales and take control of the region.
"Despedida con Mariachi": The Musical Mediation of Masculine Grief in Mexican Immigrant Funerals
Authors:   , Domínguez Lizeth C.
Published: February 2025

Music plays an important role in Mexican funeral ceremonies, acting as a vehicle for men to acceptably express emotions of bereavement. As an important symbol of mexicanidad (Mexicanness), mariachi music is often used in traditional Catholic funerals, ritualizing grief equally as a mourning of loss and a celebration of the life of a deceased person. Although a form of popular music, mariachi's secular songs go through a process of sacralization, becoming meaningful sites for experiencing grief. As a musical expression of Mexico's idealized gender norms mariachi opens an aesthetic sphere for masculine grief to be expressed, experienced, and socialized in an acceptable form. The purpose of this thesis is to investigate the musical mediation of masculine grief, experienced and ritualized within funeral ceremonies, and observed through an ethnographic study of Mexican immigrant communities.
Re-Assessing Nationalism in the Art Songs of Jaime León
Authors:   , Ávila Martínez Juan Sebastián
Published: February 2025

Colombian composer Jaime León (1921-2015) is known for his art songs. Most of the current scholarly literature about León defines him as a nationalist composer even though a majority of his songs do not appear to have nationalist traits. This document examines a representative selection of León's songs divided into three categories: songs influenced by the bambuco (the Colombian genre most present in his songs); songs whose text refers to Colombian culture; and songs without Colombian elements present in their text or music. After examination of these songs, my conclusion is that León, rather than being nationalist, was a cosmopolitan composer who used national elements as rhetorical tools in an isolated and experimental way.
Selecting Variability in Interlocking Behavioral Contingencies
Authors:   , Urbina Tomas
Published: February 2025

The current study explored how the variability or lack thereof in interlocking behavioral contingencies (IBC) may be brought under contextual control. Four undergraduates (two dyads) students participated in the current study. Dyads were instructed to play a game on a computer screen with the goal to earn as many "Congratulations" as possible. An ABABAB reversal design was used. A Lag 1 schedule of cultural consequence delivery for IBC topography was set in the variability (VAR) condition. During the repeated (REP) condition only one IBC topography was reinforced. For one of the two dyads, the variability of IBC topography was brought under contextual control. It is important to explore the behavioral processes at the cultural level to understand prediction and control of cultural phenomena.
Job Satisfaction, Organizational Commitment, and Turnover Intention of Teachers Using Computer-Based Curriculum Delivery in a Drop-Out Recovery High School
Authors:   , Beauchamp Joey
Published: February 2025

This current study examined the job satisfaction and turnover intention of teachers working in a drop out recovery program using online curriculum. The subjects of the study were from one charter school district in north Texas that is designated as a drop out recovery program. This qualitative case study used interviews and focus groups to examine eight different areas of teacher job satisfaction to examine factors that influence a teacher's intent to quit or remain at a school. Previous research showed a connection between job satisfaction levels and the intent of a teacher to terminate employment or not. Previous research had not looked into this specific school environment. Results showed that compensation was the largest factor in job satisfaction but negative feelings could be overcome if other areas of importance for teachers brought positive job satisfaction. Overall, teachers in this environment were more likely to have high job satisfaction and less likely to terminate employment.
The Impact of Little Kids Rock Modern Band Programs on Elementary Mathematics Achievement
Authors:   , Buckner Linda Y
Published: February 2025

Overwhelming evidence supports the fact that music instruction greatly increases academic achievement on standardized test scores at the elementary, middle and high school level. When school districts face budget deficits, typically they alleviate the shortfall by eliminating music programs. Currently in Dallas ISD, teacher salaries are affected by how well a student performs on the STAAR exam. In this quantitative, causal-comparative study, 5th grade music STAAR mathematics scores are investigated to discover if instrumental music instruction using the Little Kids Rock Modern Band method improves academic achievement on the STAAR exam.
Class Enumeration and Parameter Bias in Growth Mixture Models with Misspecified Time-Varying Covariates: A Monte Carlo Simulation Study
Authors:   , Palka Jayme M.
Published: February 2025

Growth mixture modeling (GMM) is a useful tool for examining both between- and within-persons change over time and uncovering unobserved heterogeneity in growth trajectories. Importantly, the correct extraction of latent classes and parameter recovery can be dependent upon the type of covariates used. Time-varying covariates (TVCs) can influence class membership but are scarcely included in GMMs as predictors. Other times, TVCs are incorrectly modeled as time-invariant covariates (TICs). Additionally, problematic results can occur with the use of maximum likelihood (ML) estimation in GMMs, including convergence issues and sub-optimal maxima. In such cases, Bayesian estimation may prove to be a useful solution. The present Monte Carlo simulation study aimed to assess class enumeration accuracy and parameter recovery of GMMs with a TVC, particularly when a TVC has been incorrectly specified as a TIC. Both ML estimation and Bayesian estimation were examined. Results indicated that class enumeration indices perform less favorably in the case of TVC misspecification, particularly absolute class enumeration indices. Additionally, in the case of TVC misspecification, parameter bias was found to be greater than the generally accepted cutoff of 10%, particularly for variance estimates. It is recommended that researchers continue to use a variety of class enumeration indices during class enumeration, particularly relative indices. Additionally, researchers should take caution when interpreting variance parameter estimates when the GMM contains a misspecified TVC.

Identification, Characterization and Engineering of UDP-Glucuronosyltransferases for Synthesis of Flavonoid Glucuronides
Authors:   , Adiji Olubu Adeoye
Published: February 2025

Flavonoids are polyphenolics compounds that constitute a major group of plant specialized metabolites, biosynthesized via the phenylpropanoid/polymalonate pathways. The resulting specialized metabolites can be due to decoration of flavonoid compounds with sugars, usually glucose, by the action of regiospecific UDP-glycosyltransferase (UGT) enzymes. In some cases, glycosylation can involve enzymatic attachment of other sugar moieties, such as glucuronic acid, galactose, rhamnose or arabinose. These modifications facilitate or impact the bioactivity, stability, solubility, bioavailability and taste of the resulting flavonoid metabolites. The present work shows the limitations of utilizing mammalian UDP-glucuronosyltransferases (UGATs) for flavonoid glucuronidation, and then proceeds to investigate plant UG(A)T candidates from the model legume Medicago truncatula for glucuronidating brain-targeted flavonoid metabolites that have shown potential in neurological protection. We identified and characterized several UG(A)T candidates from M. truncatula which efficiently glycosylate various flavonoids compounds with different/multiple regiospecificities. Biochemical characterization identified one enzyme, UGT84F9, that efficiently glucuronidates a range of flavonoid compounds in vitro. In addition, examination of the ugt84f9 gene knock-out mutation in M. truncatula indicates that UGT84F9 is the major UG(A)T enzyme that is necessary and sufficient for attaching glucuronic acid to flavonoid aglycones, particularly flavones, in this species. Finally, the identified UG(A)T candidates were analyzed via homology modeling and site-directed mutagenesis towards increasing the repertoire of UG(A)Ts applicable for synthesis of flavonoid glucuronides with potential human health benefits in neurological protection.
A Method of Combining GANs to Improve the Accuracy of Object Detection on Autonomous Vehicles
Authors:   , Ye Fanjie
Published: February 2025

As the technology in the field of computer vision becomes more and more mature, the autonomous vehicles have achieved rapid developments in recent years. However, the object detection and classification tasks of autonomous vehicles which are based on cameras may face problems when the vehicle is driving at a relatively high speed. One is that the camera will collect blurred photos when driving at high speed which may affect the accuracy of deep neural networks. The other is that small objects far away from the vehicle are difficult to be recognized by networks. In this paper, we present a method to combine two kinds of GANs to solve these problems. We choose DeblurGAN as the base model to remove blur in images. SRGAN is another GAN we choose for solving small object detection problems. Due to the total time of these two are too long, we still do the model compression on it to make it lighter. Then we use the Yolov4 to do the object detection. Finally we do the evaluation of the whole model architecture and proposed a model version 2 based on DeblurGAN and ESPCN which is faster than previous one but the accuracy may be lower.
The Guaraldi Sound: The Musical Devices that Characterize Vince Guaraldi's Improvisational and Compositional Idiom
Authors:   , Huntley Alec Villars
Published: February 2025

Vince Guaraldi (1928-1976) was a jazz pianist who achieved tremendous financial and commercial success in the 1960s with his popular recordings and his work for the Peanuts animated shorts. He cultivated a musical style that drew from several identifiable sources: boogie-woogie, bebop, Brazilian and Afro-Cuban jazz, and rock ‘n' roll. The result was a distinct approach to jazz which, although it may not have been as influential as that of some of his contemporaries, nevertheless constituted a unique and personal voice—what several commentators have referred to as the "Guaraldi sound." This dissertation considers the entire range of Guaraldi's recorded output in order to define and catalog many elements that contributed to Guaraldi's musical style. Using an analytical framework drawn from the work of Leonard Meyer and Benjamin Givan, this study describes both Guaraldi's improvisational style—the licks, patterns, and phrases that he plays while soloing—and common elements of his compositions—the chord progressions, grooves, and other features that are particularly idiomatic. Also discussed are Guaraldi's status within the established jazz canon and the disparity between his widespread popularity and his lukewarm critical reputation. The discussion and analyses provide useful insights for fans of Guaraldi, fans of Peanuts music, jazz musicologists, and any seeking to emulate the Guaraldi sound.
Caregiver Knowledge of Risk Factors Associated with Complex Congenital Heart Disease and Quality of Life Outcomes
Authors:   , Hutchinson Jessica B
Published: February 2025

Congenital heart disease is the most common birth defect globally, affecting both children and their families. Twenty –five percent of children experiencing a CHD birth defect are diagnosed with complex CHD (cCHD), signifying critical heart dysfunction requiring one or more open-heart surgeries during the first year of life. With medical advances, cCHD survival rates have almost tripled in the last three decades. This has resulted in an increase in the number of morbidities associated with cCHD, which is drastically impacting the need to support quality of life outcomes for a child with cCHD and their family. The two most prevalent unaddressed risks for quality of life outcomes in the cCHD population are child and caregiver mental health and child's neurodevelopmental disabilities.

The two most prevalent unaddressed risks for quality of life outcomes in the cCHD population are child and caregiver mental health and child's neurodevelopmental disabilities. The present study sought to address the relationship between caregiver knowledge of cCHD developmental challenges (i.e., outcomes related to neurodevelopmental disabilities, mental health, and provider quality-care approach) and children's and caregiver's quality of life outcomes, inclusive of academic functioning ability of children with cCHD, children with cCHD and their caregivers' mental health functioning, and the overall satisfaction with the nature of the healthcare provider of the child with cCHD. A total sample size of N = 46 participants were included in the current study. Results that caregivers' knowledge of cCHD risks to quality of life outcomes explained a much greater percentage of the variance in caregiver satisfaction with healthcare providers (R2 = 0.350, p < 0.001) compared to number of surgical interventions (R2 = 0.058, p = 0.047). Clinical implications and implementation for use of a holistic, integrated approach are strengthened by the study findings.
The Role of Interface in Crystal Growth, Energy Harvesting and Storage Applications
Authors:   , Ramesh Dinesh
Published: February 2025

A flexible nanofibrous PVDF-BaTiO3 composite material is prepared for impact sensing and biomechanical energy harvesting applications. Dielectric polyvinylidene fluoride (PVDF) and barium titanate (BaTiO3)-PVDF nanofibrous composites were made using the electrospinning process based on a design of experiments approach. The ultrasonication process was optimized using a 2k factorial DoE approach to disperse BaTiO3 particles in PVDF solution in DMF. Scanning electron microscopy was used to characterize the microstructure of the fabricated mesh. The FT-IR and Raman analysis were carried out to investigate the crystal structure of the prepared mesh. Surface morphology contribution to the adhesive property of the composite was explained through contact angle measurements. The capacitance of the prepared PVDF- BaTiO3 nanofibrous mesh was a more than 40% increase over the pure PVDF nanofibers. A comparative study of dielectric relaxation, thermodynamics properties and impact analysis of electrospun polyvinylidene fluoride (PVDF) and 3% BaTiO3-PVDF nanofibrous composite are presented. The frequency dependent dielectric properties revealed micro structural features of the composite material. The dielectric relaxation behavior is further supported by complex impedance analysis and Nyquist plots. The temperature dependence of electric modulus shows Arrhenius type behavior. The observed non-Debye dielectric relaxation in electric loss modulus follows a thermally activated process which can be attributed to a small polaron hopping effect. The particle induced crystallization is supported with thermodynamic properties from differential scanning calorimetric (DSC) measurements. The observed increase in piezoelectric response by impact analysis was attributed to the interfacial interaction between PVDF and BaTiO3. The interfacial polarization between PVDF and BaTiO3 was studied using density functional theory calculations and atomic charge density analysis. The results obtained indicates that electrospinning offers a potential way to produce nanofibers with desired crystalline nature which was not observed in molded samples. In addition, BaTiO3 can be used to increase the capacitance, desired surface characteristics of the PVDF nanofibers which can find potential application as flexible piezoelectric sensor mimicking biological skin for use in impact sensing and energy harvesting applications.
Factors Impacting Performance Measurement and Knowledge Transfer in a Training Environment
Authors:   , Rosellini Amy
Published: February 2025

Most training performance measurement tools rely heavily on quantitative metrics that do not consider factors impacting knowledge transfer and behavioral change such as social relationships and company culture. This study observed a training performance measurement tool for a major U.S.-based airline. Analysis of the measurement tool consists of: a pilot study providing a baseline for the current gaps in training performance measurement, a survey of flight attendants to understand how company cultural and social factors impact learning and knowledge transfer, and focus groups to provide an in-depth analysis of what the underlying company cultural and social factors are. Both quantitative and qualitative analysis were utilized to identify the impact of cultural factors and social relationships on performance measurement to provide in-depth understanding of the role of tacit knowledge transfer in the training environment. Results show that cultural factors such as empathy, coaching, and on-the-job training, negatively impact the accuracy of flight attendants' ability to measure learning and knowledge transfer. A second finding shows social factors, personality, and agreement, show a strong trend towards negatively affecting the ability to accurately measure learning and knowledge transfer. The proposed knowledge transfer measurement model was further modified to reflect the findings and the results of this study. Further recommendations include altering the measurement tool, prioritization of skills, and communicating purpose.

A Performance Guide to Wu Yiming's "A Poem Carved in Stone"
Authors:   , Xie Dongni
Published: February 2025

A Poem Carved in Stone, a work for piano solo by Washington DC-based Chinese composer Wu Yiming was composed in Spring 2020 and is dedicated to the author of this dissertation. The piece is inspired by the poetry of Han Shan, a recluse who lived during the Tang Dynasty (618-907 A.D.). His poetry is in Chan (Zen) tradition. Wu depicts the imagery and philosophy in Han Shan's poetry through highly complex rhythms, extreme sound effects and pitches, tone clusters, and extended piano techniques. This dissertation provides practical instructions for achieving these effects and executing the unconventional techniques found in this piece, which include playing inside of the piano, various standing and sitting positions, and coordination and balance. A guide to interpret this piece is from both the composer's and the performer's perspective. Observations are drawn directly from communications and coaching received from the composer. This study briefly explores the historical and cultural context of Han Shan's poetry and discusses how Wu's use of modern western compositional devices reflects the Zen philosophy. An interview with the composer is included along with an overview of both his compositions and those of composers who influenced him. It is hoped that this dissertation will encourage pianists who are not experienced with non-traditional techniques to explore new music from living composers.
Atomic Layer Deposition of Boron Oxide and Boron Nitride for Ultrashallow Doping and Capping Applications
Authors:   , Pilli Aparna
Published: February 2025

The deposition of boron oxide (B₂O₃) films on silicon substrates is of significant interest in microelectronics for ultrashallow doping applications. However, thickness control and conformality of such films has been an issue in high aspect ratio 3D structures which have long replaced traditional planar transistor architectures. B₂O₃ films are also unstable in atmosphere, requiring a suitable capping barrier for passivation. The growth of continuous, stoichiometric B₂O₃ and boron nitride (BN) films has been demonstrated in this dissertation using Atomic Layer Deposition (ALD) and enhanced ALD methods for doping and capping applications. Low temperature ALD of B₂O₃ was achieved using BCl₃/H₂O precursors at 300 K. In situ x-ray photoelectron spectroscopy (XPS) was used to assess the purity and stoichiometry of deposited films with a high reported growth rate of ~2.5 Å/cycle. Free-radical assisted ALD of B₂O₃ was also demonstrated using non-corrosive trimethyl borate (TMB) precursor, in conjunction with mixed O₂/O-radical effluent, at 300 K. The influence of O₂/O flux on TMB-saturated Si surface was investigated using in situ XPS, residual gas analysis mass spectrometer (RGA-MS) and ab initio molecular dynamics simulations (AIMD). Both low and high flux regimes were studied in order to understand the trade-off between ligand removal and B₂O₃ growth rate. Optimization of precursor flux was discovered to be imperative in plasma and radical-assisted ALD processes. BN was investigated as a novel capping barrier for B₂O₃ and B-Si-oxide films. A BN capping layer, deposited using BCl₃/NH₃ ALD at 600 K, demonstrated excellent stoichiometry and consistent growth rate (1.4 Å/cycle) on both films. Approximately 13 Å of BN was sufficient to protect ~13 Å of B₂O₃ and ~5 Å of B-Si-oxide from atmospheric moisture and prevent volatile boric acid formation. BN/B₂O₃/Si heterostructures are also stable at high temperatures (>1000 K) commonly used for dopant drive-in and activation. BN shows great promise in preventing upward boron diffusion which causes a loss in the dopant dose concentration in Si. The capping effects of BN were extended to electrochemical battery applications. ALD of BN was achieved on solid Li-garnet electrolytes using halide-free tris(dimethylamino)borane precursor, in conjunction with NH₃ at 723 K. Approximately 3 nm of BN cap successfully inhibited Li₂CO₃ formation, which is detrimental to Li-based electrolytes. BN capped Li-garnets demonstrated ambient stability for at least 2 months of storage in air as determined by XPS. BN also played a crucial role in stabilizing Li anode/electrolyte interface, which drastically reduced interfacial resistance to 18 Ω.cm², improved critical current density and demonstrated excellent capacitance retention of 98% over 100 cycles. This work established that ALD is key to achieving conformal growth of BN as a requirement for Li dendrite suppression, which in turn influences battery life and performance.
The Emancipation of the Bass Clarinet: Harry Sparnaay and the Development of Solo Bass Clarinet Repertoire
Authors:   , Cameron Erin
Published: February 2025

Harry Sparnaay was a major contributor to the development of unaccompanied works for the bass clarinet and commissioned over 100 pieces for bass clarinet alone. While Sparnaay's book, The Bass Clarinet: A Personal History, includes a list of works written for him, there is minimal information available regarding most of these pieces. This project fills the information gap for this repertoire by providing publication status/score availability, performance challenges, recording history, program notes, and composer information. Each work is classified into three categories based on its publication status and recording history, providing a framework for understanding which works have entered the standard repertoire for the instrument.
Efficient Linear Secure Computation and Symmetric Private Information Retrieval Protocols
Authors:   , Zhou Yanliang
Published: February 2025

Security and privacy are of paramount importance in the modern information age. Secure multi-party computation and private information retrieval are canonical and representative problems in cryptography that capture the key challenges in understanding the fundamentals of security and privacy. In this dissertation, we use information theoretic tools to tackle these two classical cryptographic primitives. In the first part, we consider the secure multi-party computation problem, where multiple users, each holding an independent message, wish to compute a function on the messages without revealing any additional information. We present an efficient protocol in terms of randomness cost to securely compute a vector linear function. In the second part, we discuss the symmetric private information retrieval problem, where a user wishes to retrieve one message from a number of replicated databases while keeping the desired message index a secret from each individual database. Further, the user learns nothing about the other messages. We present an optimal protocol that achieves the minimum upload cost for symmetric private information retrieval, i.e., the queries sent from the user to the databases have the minimum number of bits.
Experimental Investigation on Efficiency of Fresnel Lenses with Different Manufacturing Methods
Authors:   , Sexton Ai Jiang
Published: February 2025

Non-imaging Fresnel lenses have been playing an important role in improving the efficiency of the solar energy systems. Many researchers and scientists have devoted their research to optimize the design of the Fresnel lenses. Before it can contribute to energy efficiency increase, a Fresnel lens with optimized design will first need to be fabricated with the most cost-effective method as well as the best quality fabrication as possible. If targeted in a commercial market, feasibility of mass production with a minimum fabrication time would also be a consideration. To bring the design optimization of a Fresnel lens from a conceptual theory to a real-life increase in energy efficiency, the lens needs to be fabricated, tested, compared, and analyzed. This research thesis is intended to explore the performance of the lenses with optimized design through experimental investigations. The design optimization was achieved by a previous PhD student at UNT. A total of six lenses fabricated with four different methods along with two purchased lenses were tested with two different approaches. Multiple testing routes were conducted within a 10-month period to observe the effects of material decomposition and degradation on the lens performance. The resulting experimental data has provided a solid base for analyzing the performance of the lenses, in particular, the energy conversion efficiency increase of the solar cell by using each lens. The potential cause of the performance variation can be extracted from the comparison and evaluation.
An Anthology of Tenor Arias from Korean Operas
Authors:   , Joo Kwan Kyun
Published: February 2025

The first Western opera to be performed in Korea was Verdi's La Traviata on January 16, 1948, by the Joseon Opera Company. The first Korean opera, Chunhyangjeon by Jae Myung Hyun, premiered at the Korean National Theater in May 1950, just before the outbreak of the Korean War. Daejeon.go.kr reports that since that year approximately 200 Korean operas have been produced in Korea. Nevertheless, there have been consistent efforts to create and introduce Korean operas to the public. Most of them ended up being "one-off" performances with a single production. Most research on Korean opera has focused on its history, the challenges of producing new operas, or an analysis of selected Korean operas. This study equips singers with the following: pertinent historical background with the libretto, a synopsis, research regarding the composer and librettist, a character analysis, vocal and textual analysis of the selected opera arias, instruction regarding the Korean language, IPA, and a word-by-word translation of the text. I also make recommendations for tenor arias from Korean operas for singers with specific voice types.
Information Seeking Behaviors of Transitioning Veterans When Job Hunting in North Texas
Authors:   , Eaves Tresia D.
Published: February 2025

This study explored a part of our population that can be misunderstood, marginalized, and underserved: veterans who are seeking to transition from the military to employment in North Texas. At the time of this research (before the COVID-19 pandemic), overall unemployment in North Texas was only 3.9%.Veteran unemployment was calculated at approximately the same before considering the underemployed veterans or those who have given up finding employment (and before the COVID-19 global pandemic), and that calculation likely exceeds 16-18% according to the Texas Workforce Commission. By understanding the information-seeking behaviors of the veteran population targeting North Texas for future employment, their ability to find useful information for successful relocation, attainment of employment, and the resources that enables their sense-making processes, the services provided to veterans seeking employment can be improved. Further understanding can be gained by using a qualitative approach that references Dervin's sense making model (SMM) as the framework. The revelations and conclusions can be used to improve existing programs, inspire new programs, and provide answers that are useful to the Veteran's Administration (VA), other veteran-focused organizations, policymakers, non-profits who serve veterans, veterans themselves, and future employers who enable successful transitions by providing satisfying and inclusive employment opportunities for veterans.
