The Impact Of Incorporating Self-Myofascial Release Into Voice Lessons: A Six-Week Study, Benjamin Patrick Stogner

Theses and Dissertations

The purpose of this study is to investigate the integration of Self Myofascial Release (SMR) techniques within voice lessons over six weeks; aiming to alleviate muscular tension, enhance vocal performance, and improve singers' overall well-being. The study employed a qualitative pre-test/post-test design. The data collected indicates that while SMR offers significant benefits, it is impractical to incorporate a comprehensive routine into applied lessons. However, using SMR techniques in vocal warm-up routines, and encouraging the student to use SMR techniques on their own, yielded promising results. Consistent SMR application led to improved posture, jaw mobility, and overall well-being, with older participants …

Adverse Childhood Experiences And Social Determinants Of Health In Relation To Cigarette Smoking And E-Cigarette Use Among Adults, Kankana Sengupta

Theses and Dissertations

Cigarette smoking is the leading cause of preventable morbidity and premature mortality in the U.S. and other high-income nations. E-cigarette use or vaping is an addictive behavior. During the past 5 years, the prevalence of e-cigarette use has increased markedly in U.S. adolescents and young adults. The public health implications of this increased prevalence are unclear. Adverse childhood experiences (ACEs) are associated with cigarette smoking in adulthood. However, the pathway from experiencing ACEs in childhood to smoking cigarettes or using e-cigarettes in adulthood is not clearly understood. Additional factors experienced between childhood and adulthood might either increase or decrease the …

A Field-Programmable Metamaterial Using Memristor As A Stable Switcher, Taekuk Hong

Theses and Dissertations

Before the memristor was discovered, there were RLC circuits as representative passive devices. However, the fourth fundamental two-terminal circuit has been discovered by Dr. Leon Chua in 1971 and has been called a memristor. The memristor is a compound word of memory and resistor, and is an element whose resistive value is not constant and whose resistive value changes depending on the applied voltage and is recorded as a memory. It is mainly used in resistive switching and is the center of this research theme. A metamaterial is artificially created material that has never been found in nature. The theory …

Truth And Knowledge In A Literary Text And Beyond: Lydia Chukovskaya’S Sofia Petrovna At The Intersections Between Selves, Culture, And Paratext, Angelina Rubina

Theses and Dissertations

Although Lydia Chukovskaya’s novella Sofia Petrovna (1965) is not considered to be an autobiographical work, the life story of its protagonist, Sofia Petrovna, and the life of Lydia Chukovskaya herself have certain parallels. Chukovskaya’s very own fate, which she described in the foreword to the novella and in her other biographical works, is often viewed inseparably from the novella. However, among the many connections between the fictional fate of Sofia Petrovna and the real fate of Lydia Chukovskaya, one aspect that has not been properly explored by the critics is the “dialogue” between the author and the protagonist with respect …

Robocat: An Autonomous Surface Vehicle (Asv) For Near-Surface Hydrodynamic Measurements In Buoyant Plumes. Development And Case Study, Christopher Tom Papageorgiou

Theses and Dissertations

The study of near surface processes in plumes and other stratified environments requires the collection of hydrodynamic and hydrographic data near the sea surface at high temporal and spatial (in the vertical) resolution. This need led to the design and development of a low-cost autonomous surface vehicle (ASV) equipped with a 5-beam acoustic Doppler current profiler (Nortek 1000 Signature) capable of measuring the vertical structure of both mean flow and turbulence dissipation rate (ε) as close as 30 cm below the sea surface. The ASV is a small catamaran-like platform propelled by four thrusters arranged in an Omni-X configuration, to …

A Comparative Measure Of Judicial Legitimacy, Rahul Hemrajani

Theses and Dissertations

In the Federalist papers, Hamilton emphasized the vulnerability of courts as the weakest branch of government, lacking both the power of the "purse" and the "sword." Consequently, courts can secure compliance with their decisions only if people believe in the legitimacy of their actions. Courts that are seen as legitimate by the public can better prevent governmental overreach, enhance the rule of law, and protect democratic rights. However, there is no consensus on how to validly measure the legitimacy of courts. Additionally, existing research on legitimacy focuses on courts in the United States; we know little about judicial legitimacy in …

The Role Of Insulin Signaling In Controlling Oogenesis In Drosophila Melanogaster, Tancia W. Bradshaw

Theses and Dissertations

Adult stem cell activity responds to organismal nutrient status to maintain and support tissue homeostasis. Despite the intricate relationship between dietary input, adipose tissue and peripheral organ function, we are at the tip of the iceberg regarding our understanding of the cellular and molecular mechanisms underlying adipose communication to other tissues. The Drosophila ovary receives nutritional signals from the fat body with multiple nutrient-sensing pathways functioning in adipocytes to control distinct stages of oogenesis. Insulin/insulin-like growth factor signaling (IIS) within adult adipocytes remotely controls oocyte production at distinct stages of oogenesis. The PI3K/Akt1 axis in adipocytes promotes germline stem cell …

Examining The Perceptions And Knowledge Of School Administrators In Special Education, Maranda Hayward

Theses and Dissertations

School administrators play a critical role in special education and it is essentially their responsibility to ensure policies, procedures, and practices are carried out in accordance with the law. This requires that school administrators know the requirements of the law and research-based practices in special education. Researchers have shown that school administrators perceive themselves as having adequate knowledge and understanding of special education law; however, there is a lack of research on the practical knowledge of school administrators in special education. This study, using hypothetical scenarios, examined whether school administrators were able to determine if a decision or action made …

The Unsung Heroes For Intercollegiate Athletics: Examining The Dialogic Principles Of Communication In Community College Athletic Departments, Matthew Alan Stilwell

Theses and Dissertations

The purpose of this study was to explore community college athletic departments and how they connect and facilitate messages to their stakeholders. With limited resources, it’s important to understand how the athletic departments are applying best strategies and principles of relational management. Therefore, the goal and importance of this project was to explore how a mass communication tool in Twitter and how it is used in community college athletics, an area that is not a focal point in either collegiate athletics or sport communication scholarship. Using Kent and Taylor’s (1998) dialogic principles of communication as a guide for this project, …

Racial Orientations: A Phenomenological Approach, Nicholas Mazur

Theses and Dissertations

Given the orienting complexities of how race is developed, experienced, performed, and understood, the author argues that a phenomenological approach to uncovering what makes a racial orientation might provide a better understanding of the role of consciousness, the body, and history in race relations. Incorporating knowledges of critical race theory (CRT) and critical whiteness studies (CWS), the author aims to pivot sociological discussions about race into the phenomenological field where racial orientations can be understood from another dimension. Specifically, the author offers as an additional theoretical framework in the form of a phenomenological methodology for pedagogies addressing race and issues …

Oscars Vs. Ozone: The Motion Picture Industry’S Impact On Climate Change And What They Are Doing About It, Alexis J. Simpson

Senior Theses

This thesis focuses on demonstrating that the motion picture industry, which includes film and television production (and thus will also be called ‘the film and television industry’), has notably contributed to the global effects of climate change. Such contributions can stem from the industry’s emissions and waste, with examples including travel for cast and crew, energy use for production equipment (some of which run on diesel), and disposable physical sets and costumes. The intention here is to give an accurate picture of current production practices and share examples of progress in the industry that are combating the negative impacts of …

Country-Of-Origin Information Reports: The Political And Legal Geographies Of Central American Migrants, Elise Dosch

Senior Theses

Country-of-origin information reports provide purportedly objective information on the political, economic, security, and humanitarian situation of a certain country. Within the context of asylum adjudication, country-of-origin information reports provide contextual information on the country-of-origin of the person seeking asylum. Academic literature on the legal use and application of these reports is limited, with the majority of research being contained within the European context. This thesis uses interviews with legal practitioners from the United States to investigate the use of country-of-origin information reports in the asylum adjudication process. These interviews revealed the uses of country-of-origin information reports by 3 key actors …

"The Opium Of The People" - The Effects Of Soviet State Atheism On The Muslims Of Central Asia, Joshua Hughes

Senior Theses

This thesis explores the Soviet Union’s approach to Islam in the Central Asian republics of Kyrgyzstan, Kazakhstan, Uzbekistan, Tajikistan, and Turkmenistan and the effects that these policies have had on believers following the collapse of the Soviet Union. As the first nation to adopt atheism as official policy, the Soviet Party-state employed many tactics to suppress Islam in the region through violence, propaganda, and strict control. Relying on existing literature written on the topic, I begin by offering a historical analysis of the attacks on Islam in the 1920s and 1930s. In an attempt to expand the scope of English-language …

Correlates Of Immunization Timeliness In Three South Asian Countries: Secondary Analysis Of Demographic And Health Surveys, Tanzir Ahmed Shuvo

Theses and Dissertations

Despite the availability of effective vaccines, 1.5 million children under the age of 5 years die every year because of vaccine preventable diseases. Improvements in vaccine delivery infrastructure have resulted in relatively high coverage of vaccines, but many children are not receiving their vaccines on a timely basis. Timely administration of routine vaccines recommended by the Expanded Programme on Immunization (EPI) ensures maximum efficacy. It is vital to explore rates of vaccination timeliness and the correlates of timely vaccination among children to design targeted interventions for improving both coverage and timeliness. We conducted a secondary data analysis of the Demographic …

Dephosphorylation Of Mpk6 And Mpk3 By Phosphatases Modulates Responses To Herbivory In Arabidopsis, Claire Teresa Hann

Theses and Dissertations

As sessile organisms, plants rely on extracellular signals and chemical responses to defend against stressors. Extracellular stress signals inducing defense responses originate both from biotic or abiotic threats, and from products of tissue damage or hormones. In defense against herbivores, essential responses include rapid generation of jasmonic acid (JA) at the wound site, followed by the global expression of genes that impede digestion and growth. Early defense gene expression amplifies JA production, while later JA-responsive gene expression causes the accumulation of defense products. MAP kinase (MAPK) pathways play a central role in mediating the perception of self, non-self, and hormonal …

Computation Of High-Order Sensitivities Of Model Responses To Model Parameters—I: Underlying Motivation And Current Methods, Dan Gabriel Cacuci

Faculty Publications

The mathematical/computational model of a physical system comprises parameters and independent and dependent variables. Since the physical system is seldom known precisely and since the model’s parameters stem from experimental procedures that are also subject to uncertainties, the results predicted by a computational model are imperfect. Quantifying the reliability and accuracy of results produced by a model (called “model responses”) requires the availability of sensitivities (i.e., functional partial derivatives) of model responses with respect to model parameters. This work reviews the basic motivations for computing high-order sensitivities and illustrates their importance by means of an OECD/NEA reactor physics benchmark, which …

Rico’S Long Arm, Randy D. Gordon

South Carolina Journal of International Law and Business

RICO has for over 50 years presented something of a parlor game for lawyers, mostly because its text leaves wide latitude in interpretation. And, as is often the case with RICO, resolution of one question begets more. The Supreme Court’s recent decision in Yegiazaryan v. Smagin proves no exception. Here, the Court brought some clarity to a question left open by RJR Nabisco: viz, what must one plead and prove to satisfy the “domestic injury” requirement necessary to invoke an extraterritorial application of RICO. The Court held that a foreign plaintiff can indeed, given the right facts and circumstances, establish …

Dispute Resolution In The Badminton World Federation: Sui Generis Expert Determination?, Ilias Bantekas

South Carolina Journal of International Law and Business

The Badminton World Federation (BWF) has set up a poly-tiered dispute resolution mechanism to deal with alleged breaches of its institutional statutes. It calls these ‘judicial’ bodies even though they are not established by law. They consist of the Independent Hearing Panel (IHP) and the Sports Dispute Panel (SDP). The former entertains mostly governance-related disputes while the SDP enjoys jurisdiction for substantive sports disputes. The IHP also serves as an appellate forum against SDP decisions. Neither of these entities has been endowed with arbitral qualities and the BWF dispute settlement architecture is paradigmatic of expert determination. The two ‘judicial’ entities …

Ki-Cook: Clustering Multimodal Cooking Representations Through Knowledge-Infused Learning, Revathy Venkataramanan, Swati Padhee, Saini Rohan Rao, Ronak Kaoshik, Anirudh Sundara Rajan, Amit Sheth

Publications

Cross-modal recipe retrieval has gained prominence due to its ability to retrieve a text representation given an image representation and vice versa. Clustering these recipe representations based on similarity is essential to retrieve relevant information about unknown food images. Existing studies cluster similar recipe representations in the latent space based on class names. Due to inter-class similarity and intraclass variation, associating a recipe with a class name does not provide sufficient knowledge about recipes to determine similarity. However, recipe title, ingredients, and cooking actions provide detailed knowledge about recipes and are a better determinant of similar recipes. In this study, …

Ecg Recordings As Predictors Of Very Early Autism Likelihood: A Machine Learning Approach, Deepa Tilwani, Jessica Bradshaw, Amit Sheth, Christian O'Reilly

Publications

In recent years, there has been a rise in the prevalence of autism spectrum disorder (ASD). The diagnosis of ASD requires behavioral observation and standardized testing completed by highly trained experts. Early intervention for ASD can begin as early as 1–2 years of age, but ASD diagnoses are not typically made until ages 2–5 years, thus delaying the start of intervention. There is an urgent need for non-invasive biomarkers to detect ASD in infancy. While previous research using physiological recordings has focused on brain-based biomarkers of ASD, this study investigated the potential of electrocardiogram (ECG) recordings as an ASD biomarker …

Study Of Digital Algan Alloy Based Heterostructures Using Aln/Gan Short Period Superlattice, Mohammad Kamal Hussain

Theses and Dissertations

Ultrawide Bandgap (UWBG) and Extreme Bandgap (EBG) AlxGa1-xN (x > 0.40) alloys with EG > 4.2 eV are potential candidates for high temperature and high voltage applications, compared to Wide Bandgap (WBG) GaN-based lateral channel devices. Since critical electric field (Ec) scales as (Eg)^2.5, theoretically AlGaN alloys can sustain large electric field before breaking down. However, achieving linear ohmic contacts to the 2-dimensional electron gas (2DEG) formed at the interface of AlyGa_1-xN/ Al_xGa_1-xN (y – x ≥ 0.20) High Electron Mobility Transistors (HEMTs) is challenging. Direct contact through the AlGaN barrier is difficult due …

Hf Radar: Shining A Light On Ocean Currents, Douglas Cahl

Theses and Dissertations

High Frequency (HF) radar systems are commonly used to estimate surface ocean currents over the coastal ocean. Their range depends on their operational frequency and low frequency systems (≤ 10 MHz) can reach distances up to 200 km from the coastline. These systems are used to estimate surface currents by measuring the phase speed of wind-driven waves and comparing the measured speed with that expected theoretically; deviations from the theoretical still-water phase speed are attributed to ocean surface currents. Although HF radar systems are considered a mature technology and the accuracy of the radar-derived surface current estimates is well studied, …

The Impact Of A Literacy Program On Summer Reading Setback: Providing Access To Books And Project-Based Learning, Tiffany Gayle Robles
