A Score Of Voices: Creating And Scoring An Original Film With A Cappella Choir, Zachary James Moore

Electronic Theses and Dissertations

Film scores typically feature large instrumental ensembles, sometimes with choir added at pivotal moments. Rarely, however, is the choir entrusted with a greater percentage of the score, and far too scores explore the sonic potential that vocal music has to offer. In fact, in a recent study of 800 films, none contained a score that was completely c. Thus, the body of unaccompanied choral film scores is practically non-existent. This curious gap in repertoire inspired me to create the documentary Downstream (2023) and score it entirely with an unaccompanied choir. The full score to this new work is contained within …

Early Instruments In 21st Century Composition And An Original Composition For Saxophones And Viols, Jacob Bitinas

Electronic Theses and Dissertations

Composers continually seek new timbres and sonorities to bend to their will. The early music revival of the twentieth century has resurrected dozens of instruments that have gone unutilized in contemporary composition for centuries. The historically-informed-performance movement has now evolved to a point where early instruments and period performance techniques can add extraordinary new characters to twenty-first century compositions. This thesis explores how composers effectively utilize early instruments like the viola da gamba, harpsichord, lute, and recorder in their compositions.

The document also contains interview transcripts from eight composers and performers, including Nico Muhly, Liam Byrne, Martha Bishop, David Loeb, …

The Rise Of Wavetable Synthesis In Commercial Music And Its Creative Applications, Garrett Norman Scroggs

Tangential Flow Treatment Of Poultry Processing Wastewater Using Stainless Steel Ultrafiltration Membrane, Saubana Olorunsola Dada

Graduate Theses and Dissertations

The current treatment of poultry processing wastewater (PPW) requires a large expanse of land, takes time, and requires chemical usage. The wastewater is typically treated prior to discharge. Apart from aiming to reuse the treated water for non-potable activities, this project aimed to reduce the footprint and time required for PPW treatment. To intensify the PPW treatment units, we studied the possibility of replacing dissolved air floatation (DAF) with a stainless steel ultrafiltration membrane (SSUF). Combined PPW from all processing units taken before the first DAF and the second DAF were used for this study with no pretreatment. The SSUF …

To do this, the study set out to determine what factors influenced Arkansas teachers to leave or consider leaving, their positions and the impact that the pandemic had on those choices, and what factors influenced, or could influence, teachers to stay in their position. …

Role Of Carbohydrate Source As Part Of A Higher Protein Diet On Markers Of Metabolic Syndrome, Ada-Miette Josephine Thomas

Graduate Theses and Dissertations

Obesity has become a major health crisis in the United States and across the globe [1]. Recent findings suggest that approximately 50% of U.S. adults will have obesity and 25% will have severe obesity (body mass index (BMI) > 40 kg/m2) by the year 2030 [2]. Obesity-related cardiometabolic dysfunction is a significant public health concern [3, 4]. As rates of obesity increase, so too does prevalence of the metabolic syndrome [5]. In the United States, incidence of Metabolic syndrome (MetS) increasing, with approximately one in three adults qualifying for a diagnosis [6, 7]. MetS is a grouping of cardiometabolic risk factors …

Children’S Disclosure Of School Bullying: The Relation Between Peer Victimization, Internalizing Symptoms, Negative Affect, And Gender, Julia L. Kiefer

Graduate Theses and Dissertations

Children who are bullied by their peers are at risk for several negative developmental outcomes and are therefore advised to tell an adult when they are. However, victims of school bullying are often reluctant to disclose to adults that they are being bullied. Some bullied children also experience symptoms of anxiety or depression, which could further reduce their likelihood of telling an adult. In this study, I tested the degree to which children’s internalizing symptoms predicted their likelihood of telling adults about being bullied at school, and if this relation was exacerbated by children’s negative feelings associated with telling an …

Identifying Predictors Of Eventual Rural Practice Among Female Osteopathic Medical Students, Dana Kahl

Graduate Theses and Dissertations

The United States is facing a growing physician shortage that threatens the ability of our healthcare system to provide needed services. This shortage will be more acutely felt in rural and underserved areas. Osteopathic medical education, with its priority of primary care specialties, plays a significant role in meeting the healthcare needs of rural communities in America. The fastest-growing demographic of osteopathic physicians is women under the age of 45 (American Osteopathic Association, 2021). Additionally, for the first time in history, women outnumber men in medical schools, accounting for 51% of current medical students (Boyle, 2019). Who is admitted to …

Understanding And Tuning Magnetism In Van Der Waals Magnetic Compounds, Rabindra Basnet

Graduate Theses and Dissertations

The recently discovered two-dimensional (2D) magnetism has attracted intensive attention due to possible magnetic phenomenon arising from 2D magnetism and their promising potential for spintronics applications. The advances in 2D magnetism have motivated the study of layered magnetic materials, and further enhanced our ability to tune their magnetic properties. Among various layered magnets, tunable magnetism has been widely investigated in metal thiophosphates MPX3. It is a class of magnetic van der Waals (vdW) materials with antiferromagnetic ordering persisting down to atomically thin limit. Their magnetism originates from the localized moments due to 3d electrons in transition metal ions. So, their …

Results And Simulation Of Active Self-Assembly, Robert M. Alaniz

Theses and Dissertations

Self-assembly is the process by which simple elements in a system organize themselves into more complex structures based on a set of rules that govern their interactions. With many ways to create self-assembling systems, new models of abstraction have also arisen to handle specific mechanisms and procedures. We explore several open problems in the seeded model of Active Self-Assembly, Chemical Reaction Networks, and Surface Chemical Reaction Networks, proving new results while developing a robust simulation environment, AutoTile, to help build and test these results.

Activation Of Opa1 Processing In Differentiated Myoblast Cells, Omar Agustin Carrillo

Theses and Dissertations

Mitochondria are eukaryotic cellular organelles that play a role in energy production, apoptosis, integrated stress response, and aging. Mitochondrial dynamics is the physical fusion (interconnection) and fission (fragmentation) of mitochondria within a cell and tightly regulates mitochondrial functions. Optic atrophy 1 (OPA1) is a dynamin-related GTPase located in the inner mitochondrial membrane, and is responsible for inner mitochondrial membrane fusion. OPA1 exists in five isoforms, the two fusion-active long OPA1 (L-OPA1) and the three fusion-inactive short OPA1 (S-OPA1) isoforms. When the transmembrane potential (∆ψm) is aggravated, the inner membrane metalloprotease OMA1 is activated, causing the complete cleavage of L-OPA1 to …

Evaluation Of Black Holes In An Evolving Universe, John P. Naan

Theses and Dissertations

There are various solutions to the Einstein field equations that represent different physical assumptions, but how to represent multiple black holes within an expanding universe remains an area of open interest. The first step to resolving this question involves evaluating spacetime models that contain a single black hole in an expanding universe. Here, we are primarily interested in understanding the energy distribution of black hole models by solving Einstein's equations using the associated spacetime metric and comparing the propagation of waves within the model against other known spacetime models. Specifically, we will evaluate the combined Schwarschild-de Sitter solution under a …

Near-Optimal Control Of A Quadcopter Using Reinforcement Learning, Alberto Velazquez-Estrada

Theses and Dissertations

This paper presents a novel control method for quadcopters that achieves near-optimal tracking control for input-affine nonlinear quadcopter dynamics. The method uses a reinforcement learning algorithm called Single Network Adaptive Critics (SNAC), which approximates a solution to the discrete-time Hamilton-Jacobi-Bellman (DT-HJB) equation using a single neural network trained offline. The control method involves two SNAC controllers, with the outer loop controlling the linear position and velocities (position control) and the inner loop controlling the angular position and velocities (attitude control). The resulting quadcopter controller provides optimal feedback control and tracks a trajectory for an infinite-horizon, and it is compared with …

Racial Microaggressions: Improving Work Climates For Black School Psychologists, Portia Randle

School of Education Capstone Projects

Few studies examine Black school psychologists' experiences of racial microaggressions in the work environment. However, based on the available literature on the impact of racial microaggression on Black school psychology graduate students, it can be argued that Black school psychology practitioners' experiences with racial microaggressions are similar to graduate students in school psychology training programs. Thus, school-based practitioners are at increased risk of psychological trauma, stress, burnout, and diminished self-efficacy, all of which threaten the retention of Black psychologists. This capstone project provides an overview of racial microaggressions, examines the impact of microaggressions on the practice of school psychology, and …

Winter Hardy Small Cereals For Grazing Or Silage In Eastern Nebraska, Abigail M. Sartin

Department of Animal Science: Dissertations, Theses, and Student Research

Two, 3-year studies were conducted to evaluate the value of cereal rye, winter wheat, and winter triticale as forage sources for either for silage or early spring grazing. For silage, the objective was to evaluate species and maturity effects on dry matter yield, nutritive value, and fermentation of small cereal silage. There are no major differences between wheat, rye, or triticale in terms of the relative timing of each species reached each maturity stage. There are no differences among species in dry matter (DM) yield, except for wheat which tends to decline at soft dough due to senescence of the …

Surviving The Stigma: Incorporating Mental Health Literacy To Increase Help-Seeking In California First Responders, Yvonne C. Newson

Master's Projects and Capstones

First responders are at risk of developing mental health problems due to repeated exposure to traumatic incidents, increasing their chance of developing Post Traumatic Stress Disorder, substance abuse, suicidal ideation, and suicide. Unfortunately, first responders do not recognize that they may have a mental illness and are reluctant to seek help. This paper will discuss the prevalence of mental health problems among first responders and the barriers to their help-seeking. These barriers include the stigma around mental illness within the culture, the assessability of professional help, and the lack of mental health literacy regarding their well-being. Further discussion will focus …

Methods To Reduce Nitrogen And Carbon Losses From Finishing Beef Cattle, Hanna K. Cronk

Department of Animal Science: Dissertations, Theses, and Student Research

A finishing experiment evaluated the effect of incremental supplemental rumen-protected lysine on beef cattle performance. All cattle were fed the same diet of high moisture corn, dried rolled corn, modified distillers grains plus solubles, corn silage, and supplement with inclusion levels of lysine ranging from 0 to 7 grams/day, in 1 g increments. Dry matter intake (P ≤ 0.04) and ADG (P ≤ 0.04) decreased linearly as supplemental lysine increased in the diet with no effect on final carcass adjusted feed efficiency (P ≥ 0.34). In the initial 64 days of the experiment, increasing lysine in the …

Surviving the COVID-19 crisis would not have been possible without the unprecedented support measures implemented worldwide. Monetary and fiscal policy tools had to be used aggressively and innovatively to withstand the adverse impact of the crisis in 2020. In order to effectively design policy interventions to achieve the desired targets while accounting for potential trade-offs, an understanding of the interaction between monetary and fiscal policies becomes a prerequisite. The changing global and local economic conditions call for rigorous and continuous research on the topic to guide policy makers in navigating through the critical times ahead of the Egyptian economy and …

The Impacts Of Cumulative Tariff Rates On Global Value Chains, Halit Yanıkkaya, Pınar Tat, Abdullah Altun

Topics in Middle Eastern and North African Economies

This study analyzes the impacts of tariffs on global value chain participation by employing value-added trade statistics and the idea of cumulative tariff rates for 12 sectors from 168 countries over the years 1990 to 2015. The main finding is that both market access and input tariff rates have significant negative impacts on sectoral global value chain participation. The effect is persistent in the analysis we employ cumulative tariff rates. Apart from these policy determinants, sector and country-level endowments such as higher relative length, capital intensity, FDI stock, and education level appear as major drivers for higher total, forward, and …
