Towards Increased Precision of the 4He:23P1→23P2 Transition Measurement Using Laser Spectroscopy

Description: Significant sub-systems were created and others enhanced providing a platform for an order of magnitude precision increase of the small 4He interval - 23P1→23P2 laser spectroscopy measurement, as well as other helium transitions. These measurements serve as tests of helium theory and quantum electro-dynamics in general. Many improvements to the original experiment are discussed and characterized. In particular, counting speed increased 10x, the signal level was doubled, a novel Doppler shift mi… more

Training the Hybrid Singer: Mixed Voice for the Bel Canto and Musical Theatre Singer

Description: Voice teachers can train versatile singers by infusing musical theatre technique within bel canto evidence-based pedagogy. Seeing these two genres as possessing similarities instead of as unrelated fields allows teachers to not only match academic knowledge with the current entertainment job market, but most importantly, possess a versatile technique allowing them to train singers to perform fluently in multiple styles: the hybrid singer. An area of confusion in both bel canto and musical the… more

Transcribing from the Baroque Guitar to the Classical Guitar: A Critical Edition of François Campion's (c1685-1747) Sonatina in D Major

Description: The main purpose of this dissertation is to offer a modern transcription and critical edition of François Campion's Sonatina in D Major, found in his Piéces de Guitare du S.r Campion from 1748. Since it is not a common practice for the modern classical guitarist to study the baroque guitar and all its idiosyncrasies, this transcription from French tablature into modern notation will make this piece accessible to all classical guitar players. Using his sonatina as an example, this dissertation c… more

True War Stories: Lies, Truth, and Recovery in the Non/Fiction of Vietnam

Description: This dissertation examines memoirs and non/fiction of the Vietnam War, written by combat veterans (Tim O'Brien, Tobias Wolff, Ron Kovic), and army nurses (Lynda Van Devanter and Joan Furey), and war correspondents (Micheal Herr), most of whom joined the antiwar movement, and used their own war wounds as incontrovertible evidence against it. Since these authors' traumatization compromised their memories of combat, their narratives feature literary devices reflective of post-traumatic stress dis… more

Understanding and Addressing the Relationship between Weight Bias and Depressive Symptoms in College Men

Description: The current study of 151 college men explored weight-related factors that contribute to depressive symptoms among undergraduate men using structural equation modeling (SEM). Results of SEM supported the hypothesis that perceived negative messages about one's body and body dissatisfaction were significant mediators of the relationship between BMI and depressive symptoms. Moreover, social connectedness and academic self-concept were significant moderators of the relationship between body dissatis… more

Understanding the Diffusion of COVID-19-Related Information on Social Media

Description: Very few studies have examined information sentiment and explored other factors that contribute to health information dissemination and sharing. In particular, there is a lack of studies that performed these combined analyses in the modern social network environment during the disease outbreaks, such as with zika, ebola, SARS, or COVID-19. This study aimed to fill the gap in the literature by investigating what drives social media users to widely disseminate health-related information during a … more

Understanding the Knowledge, Skills, and Abilities (KSAs) of Data Professionals in United States Academic Libraries

Description: This study applies the knowledge, skills, and abilities (KSA) framework for eScience professionals to data service positions in academic libraries. Understanding the KSAs needed to provide data services is of crucial concern. The current study looks at KSAs of data professionals working in the United States academic libraries. An exploratory sequential mixed method design was adopted to discover the KSAs. The study was divided into two phases, a qualitative content analysis of 260 job advertise… more

Unraveling the Effect of Atomic Configurations and Structural Statistics on Mechanical Behavior of Multicomponent and Amorphous Alloys

Description: Multicomponent high-entropy and amorphous alloys represent relatively new classes of structural materials with complex atomic configurations and exceptional mechanical properties. However, there are several knowledge gaps in the relationships between their atomic structure and mechanical properties. Understanding these critical relationships will enable novel alloy design and tailoring of their mechanical properties for desired engineering applications. In this dissertation, first-principles ca… more

The Use of Instructive Feedback to Promote Emergent Verbal Responses: A Replication

Description: Previous research has incorporated instructive feedback (IF) within mastered listener-by-name trials with two children diagnosed with autism spectrum disorder (ASD). Participants in a previous study acquired the secondary targets and also demonstrated emergent responding (i.e., listener-by-feature, tact-by-feature, intraverbal, and reverse intraverbal). The current study replicated a previous study on IF with two children with ASD. Therapists conducted a series of three sessions of mastered lis… more

Using a Slopes Difference Test to Probe Longitudinal Multilevel Interactions in an Aptitude-Treatment or Skill-by-Treatment Context: A Simulation

Description: In order to determine which interventions work best for which students, precision education researchers have examined aptitude-treatment interactions (ATI) or skill-by-treatment interactions (STI) by using multiple regression analysis. In recent years, technological innovation and greater accessibility to more advanced statistical techniques have allowed researchers to examine ATI or STI using longitudinal mixed modeling. Probing techniques for interaction effects like slopes difference tests f… more

Using Machine Learning to Develop a Calibration Model for Low-Cost Air Quality Sensors Deployed during a Dust Event

Description: Low-cost sensors have the potential to create dense air monitoring networks that help enhance our understanding of pollution exposure and variability at the individual and neighborhood-level; however, sensors can be easily influenced by environmental conditions, resulting in performance inconsistencies across monitoring settings. During summer 2020, 20 low-cost particulate sensors were deployed with a reference PM2.5 monitor in Denton, Texas in preparation for calibration. However, from mid to … more
