Laser-Induced Acoustic Signal Generation, Resonance Characterization, And Optical Sensing In Metallic Plates, Xinghang Zhao

All Theses

This thesis investigates laser-induced acoustic signal generation, resonance characterization, and optical sensing in metallic plates as a foundational study for damage-sensitive inspection. Rather than presenting a complete defect-detection system, the work focuses on how measurable acoustic responses can be generated, amplified, and interpreted in a controlled laboratory setting. Experiments showed that pulsed-laser excitation can produce strong and repeatable acoustic responses in metallic structures. Repetition-rate sweeping identified narrow resonant responses, including a cantilever resonance at 57.862 kHz and a maximum circular-disk response at an FFT frequency of 48.8 kHz with a laser repetition rate of about 49.1 kHz. High-Q resonances exceeding …

Quantifying Macrophyte Ecosystem Services And Improving Environmental Nonprofit Messaging, Peyton R. Hughey

All Theses

Environmental nonprofits are essential to the management and restoration of our natural spaces. They are also tasked with engaging the public via outreach, education, and advocacy. As natural spaces are degraded, the ability of environmental nonprofits to deliver on their missions will become increasingly important. This study aimed to improve two approaches to environmental nonprofits’ missions: ecological restoration and social media communication.

Environmental nonprofits operate with limited resources, and ecological restoration can be an exhaustive task; therefore, we explore functional restoration as a tool. In this study, we focus on the use of functional, trait-based restoration to restore ecological function …

The Impact Of Dipeptides On Product Quality In Chinese Hamster Ovary Cells, Louise C. Herman

All Theses

Biopharmaceuticals are medicines produced in cells which are used to treat diseases such as cancer. Monoclonal antibodies (mAbs) represent the majority of approved biotherapeutics. MAbs are mostly produce using Chinese hamster ovary (CHO) cells. CHO cells are favored for resiliency, scalability, and established safety, and are considered the “workhorse” organism for biopharmaceuticals.  Amino acids are a key component of cell culture media, however several amino acids have solubility limits, such as cysteine, cystine, and tyrosine.  At neutral pH, these amino acids are poorly soluble.  However, dipeptides, such as N,N'-di-L-Alanyl-L-Cystine (ACCA) have been reported to increase cysteine and cystine availability. Further, …

How Mindfulness Influences The Frequency Of Flow In Collegiate Athletes, Kelly Torres

All Theses

Flow is defined as a state of optimal experience characterized by deep focus and total absorption that has been consistently linked to enhanced performance (Csikszentmihalyi, 1990; Jackson and Csikszentmihalyi, 1999). Mindfulness, defined as present-moment awareness with acceptance and nonjudgement, has been widely used in sport psychology interventions to improve both performance and well-being (Harris et al., 2023; Kabat-Zinn, 2015; Reive, 2019). However, less is known about how and why mindfulness contributes to performance outcomes and what role flow plays. This study examined the relationship between trait mindfulness and dispositional flow among Clemson University collegiate athletes (N=144), while exploring …

Desert Ghost, Jessica Downs

All Theses

This thesis explores the relationship between landscape, memory, and the body through handmade paper installations inspired by the deserts of southwestern Utah. Drawing from personal experience of place and the loss of a childhood home, the work considers how environments are internalized and persist as shifting, sensory impressions rather than fixed geographies. The desert becomes a generative site for examining presence, transformation, and the passage of time, both geologic and personal.

I use handmade paper and installation to translate my experience of place into physical form. Paper serves as both material and metaphor; its fibers, textures, and muted tones emulate …

The Cost Of Her Journalism: Technology-Facilitated Gender-Based Violence Against Women Journalists In The Former Soviet Union Countries, Kamila Eshalieva

All Theses

Although offline gender-based violence has been studied for decades, technology-facilitated gender-based violence (TFGBV) remains a prevalent yet underrecognized phenomenon. Journalism is a field in which this form of violence is especially persistent, and women journalists face disproportionate targeting. From cyberbullying and harassment to doxxing and disinformation, TFGBV comes in a myriad of forms, each leaving lasting scars on reporters who already face elevated professional risks. The post-Soviet region is particularly concerning, given its history of repressive regimes and hostile environments for journalism. While technology has expanded the ways for new forms of violence to emerge, these incidents are often not …

Portrayals Of Miscarriage In Film And Television: A Qualitative Analysis, Geovana Leonetti Saraiva

All Theses

Entertainment media may serve as a primary source through which individuals learn about miscarriage; however, little research has examined how miscarriage is portrayed in film and television. This study addresses this gap by conducting a textual analysis of five films and five television shows using a constructivist grounded theory approach. Guided by the model of stigma communication (MSC), communication privacy management theory (CPM), and social support frameworks, the analysis explores how miscarriage is represented in entertainment media.

Findings indicate that the analyzed content frequently includes stigma-related cues—such as marks, labels, responsibility, and peril—that may contribute to the formation and reinforcement …

Design And Development Of A Perfusable Hydrogel Platform With Bioprinted Human-Endothelialized Microvascular Channels, Calvin A. Chernyatinskiy

All Theses

We developed an integrated bioprinting and perfusion platform to generate vascularized hydrogel constructs that support perfusable microchannel networks. Multiple hydrogel formulations, sacrificial ink systems, device geometries, and perfusion conditions were systematically evaluated to optimize print fidelity, mechanical stability, and cellular compatibility. Internally gelling alginate–calcium carbonate hydrogels were identified as a robust matrix, providing tunable gelation kinetics and structural stability during embedded printing. In parallel, Pluronic F-127 fugitive ink enabled reliable fabrication of continuous hollow channels due to its shear-thinning behavior and efficient post-print removal.

The finalized platform integrates stereolithographically fabricated perfusion chambers with extrusion-based bioprinting to produce three-dimensional, perfusable vascular …

Biology, Ecology And Control Of Eye Gnats In An Open Pine Ecosystem, Leela Hospach

All Theses

Eye gnats of the genus Liohippelates are bothersome flies of the family Chloropidae. They breed in moist, disturbed, sandy soils that contain organic matter, and have been implicated as vectors of conjunctivitis, bovine mastitis, and yaws. We conducted research into some basic biological and ecological characteristics. Using wild-caught gnats in a temperature-controlled incubator, we found that their activity peaks between 27°C and 41°C. Trapping at different heights above the forest floor in an open-pine savannah, we captured most gnats at 7.5 m off the ground. This may have to do with the attractiveness of the rotten egg lures we used, …

Scrolling For Support: Social Media Use, Health Information Seeking, And Social Support In Individuals With Type 1 Diabetes, Loren Myers

All Theses

Type 1 diabetes (T1D) is a lifelong chronic illness that is rapidly increasing in prevalence. Continuous treatment is necessary for proper management, but barriers to care can cause some to turn to other sources for health-related information, like social media. Given the limited research on social media use and health information seeking behaviors in people with T1D, this study aims to gain an understanding of how people with T1D use social media, where they get their health information, and how social support is related to social media behaviors among people with T1D. Adult T1D participants completed an online survey that …

Structured Representation Learning For Generalizable Deepfake Video Detection, Maowen Tang

All Theses

Deepfake video detection has become an important problem in multimedia forensics as modern generative models produce increasingly realistic facial manipulations. Although many existing detectors achieve strong performance on the datasets on which they are trained, their performance often degrades substantially on unseen manipulation methods and evaluation conditions. A major reason for this limitation is the premature collapse of spatial structure: many vision transformer based detectors aggregate patch tokens into a single global representation, thereby suppressing the localized and temporally uneven forensic cues that characterize manipulated video.

This thesis presents the Spatio-Temporal Slot Aggregation Network (ST-SAN), a video-level deepfake detection framework …

Essays On Money Search Models, Fangfang Gong

Dissertations and Theses Collection (Open Access)

This dissertation comprises three papers that use money search models to revisit the distributional welfare costs of inflation, study the optimal design of a central bank digital currency (CBDC), and investigate the role of liquidity and monetary policy in initial investment and capital reallocation in secondary markets.

The second chapter develops a micro-founded general equilibrium model of payments to revisit the distributional welfare costs of inflation. We consider different cost structures incurred by merchants when accepting cash and deposits. In equilibrium, there exists a cutoff for buyers’ money holdings, above which card payments are accepted by merchants. We calibrate the …

Metabolic And Replicative Constraints On Pathogen Virulence: Isoleucine Catabolism In Shigella And Comparative Tanapoxvirus Replication In Cell Cultures, Benecia Angelica

Masters Theses

Pathogens survive by balancing metabolic demands with environmental challenges that shape their virulence and adaptability. Shigella flexneri, a highly infectious human pathogen responsible for severe diarrheal disease worldwide, utilizes branched-chain amino acid (BCAA) metabolism to withstand stress conditions encountered within the host environment. In this study, we explored the Shigella isoleucine catabolism pathway by knocking out four genes in the S. flexneri isoleucine catabolic pathway (ilvE, fadA, fadD, and acnB) and examining their metabolism and virulence. We found that the ilvE and acnB mutants displayed reduced metabolic activity and smaller plaque size, while the fadD mutant showed decreased invasion. In …

Coloniality In Blue, Aaron Rosa

Masters Theses

This research explores Puerto Rican identity through a diasporic lens. I investigate thematic underpinnings of colonialism and sovereignty in Puerto Rico, focusing on the intersectionality of colonial history, gender, memory, objectification, identity fragmentation, cultural resilience, narrative reclamation, and the color blue through autobiographical anecdotes. The recounting of these stories is interpreted through a variety of materials linked to my relationship with their colonial histories.

Through these relationships, I have created sculptures that reflect the materials to which these bonds are linked. Through the reflection of 451 years of colonial rule, my goal is to interweave the symbology of these materials …

Scholarship As A Means For Musical Performance: An Exploration Of Johannes Brahms Violin Sonata In G Major, Op. 78, Josh Zallar

Masters Theses

Developing a quality musical performance is a complicated and time-consuming endeavor. Endless hours are spent learning a musical instrument, developing technique, and growing into a mature sound. Learning the notes, rhythms, dynamics, and basic musical markings of a score compound this task, not to mention the preparation for performing by managing nerves, among other areas of concern. Amidst the undoubtedly enormous amount of work, however, often focus gets lost. Musicians forget that, despite the inherent fact that our inner voice is heard when we perform, that it is ultimately the composer whose voice and musical meaning must be conveyed in …

Master's Theses

Suicide remains a leading cause of death among adolescents despite more access to healthcare information than ever before. Medical professionals struggle to make accurate diagnoses and catch warning signs with the overwhelming amount of data available. Machine learning algorithms, including neural networks, have previously been employed for this task, yet it remains an understudied domain.

This research aims to evaluate the capabilities of Multi-Layer Perceptron (MLP) and a selection of its successors, ResNet and MLP with a category embedding layer, at the task of predicting suicidal ideation among high-school students. This research finds ResNet to be the most capable at …

Agency Fact-Making, Haiyun Damon-Feng

Articles

Modern administrative-law scholarship, theory, and doctrine generally conceptualize agencies as engaging in three primary functions: rulemaking, enforcement, and adjudication. This understanding of agencies has informed deep debates surrounding the power, independence, and constitutional legitimacy of the administrative state. But the prevailing account is incomplete. It overlooks a fourth core function of the administrative state: its fact-making, or epistemic, function. Across the administrative state, agencies create and disseminate information in ways that are uniquely comprehensive and uniquely powerful. Agencies’ epistemic outputs include the census generated by the Census Bureau, repositories of public-health information maintained by the Centers for Disease Control and …

"Ostracized As We Are With God": Mina Loy's Anti-Career And The Search For Originality, Peyton L. Phillips

Master's Theses

Among many modernist artists, Mina Loy remains one of the most complex and allusive. Recent posthumous exposure of Loy's life and work adds to this precarity. A significant piece of Loy's life that is especially complex to contemporaries is her time spent writing. By establishing Loy's subjective relationship with her Victorian upbringing, this paper seeks to show examples of its influence on her search for originality. Mainly, the paper examines Loy's concept of originality, where that concept may have come from, and how it is reflected in her literature. The paper analyzes three of Loy's literary works, her poems "Virgins …
