In doing so, Lewis addresses new cultural navigations of shared spaces, both digital and corporeal, public and private. In addition, the artist also examines the faulty social and institutional systems that the pandemic brought to light, such as socioeconomic dynamics and voter suppression, while utilizing Kenneth Burke’s concept of the terministic screen. Games are a central theme throughout the exhibition, as they are often coded as “home” …

Forecasting Hypotension By Learning From Multivariate Mixed Responses.., Jodie Ritter

Electronic Theses and Dissertations

Blood Pressure is the main determinant of blood flow to organs. Hypotension is defined as a systolic blood pressure less than 90 mmHg or a diastolic blood pressure less than 50 mmHg. The severity and duration of hypotension is associated with low blood flow to organs often result in organ damage and a high mortality rate. Predicting hypotension prior to surgery and during the surgery can reduce the incidence and duration resulting in better patient outcomes. This thesis uses preoperative bloodwork and vital signs as well as perioperative vital signs in 5-minute increments as inputs to forecast hypotension. Hypotension can …

The Last Straw For Mixed Ensemble And Electronis., Nicholas Hall

Electronic Theses and Dissertations

The Last Straw was composed for mixed ensemble and electronics. The main idea behind this piece is twofold: a) the treatment of the pitches, articulations, and dynamics shared between instruments and how they propagate out of phase closely resembles what I would have programed on various standalone synthesizer, and b) the processing itself is treated how I would manipulate various parameters on said synthesizers to achieve different sonic modulations. All instruments are amplified through a 4.1 sound system (4 loudspeakers and subwoofer) which is setup in a circle (see the performance layout page viii). Through processing via Max/MSP, the sound …

Fabrication And Characterization Of Lactobacillus Crispatus Containing Bioprints For Bacterial Vaginosis Application., Anthony J. Kyser

Electronic Theses and Dissertations

Bacterial vaginosis (BV) is a condition in which healthy lactobacilli are replaced by an overabundance of pathogenic bacteria in the female reproductive tract. Current antibiotic treatments often fail to “cure” infection, resulting in recurrence in more than 50% of women, 6 months post-treatment. Recently, probiotics have demonstrated promise to restore vaginal health; however, as with other active agents, delivery requires once-to-twice daily administration. Recently, three-dimensional (3D)-bioprinting has enabled the fabrication of well-defined cell-laden architectures with tunable agent release, thereby presenting a novel approach with which to deliver probiotics. One promising bioink, gelatin alginate, was selected for study, due to its …

Release Kinetics Of Metronidazole From 3d Printed Silicone Scaffolds., Sydney E. Herold

Electronic Theses and Dissertations

Sustained local administration of active agents has been proposed to cure bacterial vaginosis in the female reproductive tract and restore the resident bacterial fauna. Bioprinting has shown promise for the development of systems for local agent delivery. In contrast to oral ingestion, agent release kinetics can be fine-tuned by bioprinting specialized scaffold designs tailored for particular treatments while enhancing dosage effectiveness via localized sustained release. It has been challenging to establish scaffold properties for sustained release as a function of fabrication parameters. Towards this goal, we evaluate 3D printed scaffold formulation and feasibility to sustain release of metronidazole, a representative …

Acoustofluidic Delivery Of Gene Editing Compounds For Improved Immunotherapy Processing., Riyakumari K. Patel

Electronic Theses and Dissertations

Cell-based immunotherapies are a new generation of “living-drug” treatments for cancer and other diseases. Chimeric antigen receptor (CAR) T-cell cancer therapy has shown promising results in lymphoma and B-cell malignancies. Currently, there are six FDA-approved CAR-T drugs on the market, and all of them use viral transfection for reprogramming. While viral transfection is effective, there are safety concerns due to inconsistent transfection that limit the use of CAR-T therapy. Current non-viral transfection techniques generally have lower transfection efficiency than viral transfection. Additionally, these techniques can be toxic, time-consuming, non-transportable, and expensive. To address these limitations, a novel 3D printed acoustofluidic …

The Influence Of Fraternity And Sorority Characteristics On Alcohol Exposure: Who Is At Risk?, Sydney Shupe

Electronic Theses and Dissertations

Fraternity and sorority membership has been among the highest contributing factors linked to increased exposure to alcohol consumption among college students. Many have argued that this association persists as a result of the drinking sub-culture among Greek organizations, and report that finding effective methods to minimize alcohol consumption among college students is critical. Using self-reported data from fraternity and sorority members at East Tennessee State University (n=107) the link between observed alcohol consumption and demographic characteristics of the individual Greek member and the Greek organization was examined through a quantitative lens. It was hypothesized that the demographic characteristics of the …

The Whale-Road To Road House: A Study Of The Contemporary Transmission Of Beowulf, Haley Grindstaff

Electronic Theses and Dissertations

This thesis explores three versions of Beowulf: Gareth Hinds’s graphic novel Beowulf (2007), Maria Dahvana Headley’s translation Beowulf (2020), and Rowdy Herrington’s film Road House (1989). While Hinds and Headley fail to convey Beowulf as a cultural elegy by subtracting or misrepresenting significant scenes and characters, Road House superimposes the story of Beowulf onto 1980s America. Parallels between the plots of Beowulf and Road House and Road House’s interaction with the political underpinnings of the 80s (such as Reaganomics and the AIDS epidemic) make the film one of the best at capturing the elements of cultural elegy in the …

Electronic Theses and Dissertations

The purpose of this study was to examine the effects of schema-based instruction (SBI) on the correct response of 2 second-grade students at risk for or already determined to have a learning disability (LD) of comparison difference word problems. The study was a multiple probe across participants. Although the students did not use the RUN Strategy, one student’s ability to solve the word problems improved significantly after learning the strategy. Even though time was a factor in completing everything, the other student’s score did begin to improve after learning the RUN Strategy.

Risk Gameplay Analysis Using Stochastic Beam Search, Jacob Gillenwater

Electronic Theses and Dissertations

Hasbro’s RISK, first published in 1959, is a complex multiplayer strategy game that has received little attention from the scientific community. Training artificial intelligence (AI) agents using stochastic beam search gives insight into effective strategy when playing RISK. A comprehensive analysis of the systems of play challenges preconceptions about good strategy in some areas of the game while reinforcing those preconceptions in others. This study applies stochastic beam search to discover optimal strategies in RISK. Results of the search show both support for and challenges to traditionally held positions about RISK gameplay. While stochastic beam search competently investigates gameplay on …

A Machine Learning Approach For Reconnaissance Detection To Enhance Network Security, Rachel Bakaletz

Electronic Theses and Dissertations

Before cyber-crime can happen, attackers must research the targeted organization to collect vital information about the target and pave the way for the subsequent attack phases. This cyber-attack phase is called reconnaissance or enumeration. This malicious phase allows attackers to discover information about a target to be leveraged and used in an exploit. Information such as the version of the operating system and installed applications, open ports can be detected using various tools during the reconnaissance phase. By knowing such information cyber attackers can exploit vulnerabilities that are often unique to a specific version.

In this work, we develop an …

Dental Students' Perceptions Of Dental Hygienists' Education And Scope Of Practice, Cynthia Metzger

Electronic Theses and Dissertations

Oral health is strongly correlated to systemic health in the United States. Dental professionals play a significant role in addressing the oral health and prevention of disease for populations in the United States. Because many areas in the United States lack access to dental care, the federal government considers dental hygienists part of the solution. It is now paying attention to restrictive dental hygiene scope of practice rules in each state. State dental boards, comprised mainly of dentists, make these rules based on their perception of dental hygienists' lack of education. This study explored fourth-year dental students' perceptions of the …

Cyberspace Vs Green Space: Nature’S Psychological Influence In Neuromancer, Blade Runner 2049, And The Stone Gods, Zackery Castle

Electronic Theses and Dissertations

Cyberpunk science fiction is often set in dystopian futures where capitalism and rapid technological growth have rendered the planet ecologically devastated. The people of these worlds are host to numerous mental illnesses that many attempt to cure with drugs, entertainment, or other aspects of their fast-paced existences, but these solutions are rarely successful. When characters come to embrace the remnants of the natural world, however, they typically show signs of mental healing as the result of exposure to nature. This thesis analyzes William Gibson’s Neuromancer, Denis Villeneuve’s Blade Runner 2049, and Jeanette Winterson’s The Stone Gods alongside research …

Knockdown Of C. Elegans Nad Kinases Nadk-1 Or Nadk-2 Induces An Antioxidant Response Without Affecting Lifespan, Henry Gong

Electronic Theses and Dissertations

Nearly all multicellular organisms show changes in redox balance with aging leading to oxidative damage of macromolecules. This study investigated the role of the [NADP⁺]/[NADPH] redox couple in aging. This redox couple plays an important role in maintaining tissue redox balance and becomes slightly more oxidized in aged tissues. NADPH is a major source of reducing equivalents for enzymes that detoxify hydrogen peroxide. However, catalase detoxifies hydrogen peroxide independently of NADPH. But catalase is absent from mitochondria, a major source of hydrogen peroxide, where instead glutathione plays the major role in hydrogen peroxide detoxification in an NADPH-dependent manner. …
