Identification, Pathogenicity, And Fungicide Sensitivity Of Itersonilia Perplexans Associated With Petal Spot Of Gerbera Cut Flowers In Colombia, Matheus Beger

All Theses

Petal diseases significantly affect gerbera cut flower production, as minor visual damage renders flowers unmarketable. Among those pathogens causing petal spots, Itersonilia perplexans affects some Asteraceae plants. However, this pathogen's impact on Colombian gerbera remains poorly studied. This study was designed to fill four gaps: molecular identification of Colombian isolates, confirmation of pathogenicity, standardized culture media, and fungicide sensitivity data. Four objectives were pursued: (i) isolate and identify the causal agent through sequencing the Internal Transcribed Spacer, Small Subunit and Large Subunit from the rDNA; (ii) evaluate pathogenicity on detached gerbera petals; (iii) identify optimal culture media for I. perplexans …

Energetic Eutectics: An Experimental And Computational Investigation On Explosive Deep Eutectic Solvents, Connor J. Parker

All Theses

This study reports on the incorporation an extreme gradient boosting (XGBoost) machine learning strategy tailored to identifying potential high-energy, insensitive explosive deep eutectic solvents. 1,1-diamino-2,2-dinitroethylene (FOX-7) was investigated as the explosive of interest in our eutectic modeling. The resulting predictions highlighted a wide range of binary compositions demonstrating significant depression from the FOX-7 melting temperature with >70% probabilities of formation. Subsequent computational investigation into select mixtures provided underlying stabilization energies and optimized mixture geometries, which were then assessed experimentally with near simulant compounds oxalyldihydrazide and 1-methyl-3- nitroguanidine replacing FOX-7.

Experimental results with these chosen simulants did not demonstrate classical eutectic …

"Obsessive Myth:" Disturbing The Grammar Of The Lyric And Epic In Theresa Hak Kyung Cha's "Dictee", Noelle (Nell) Kriegel

All Theses

The archival text Dictée by Theresa Hak Kyung Cha spans many genres, making it a highly hybrid text. Cha uses personal letters, official government documents, images, prose, dictation exercises, translations, and poetry to create a composite identity of women neglected through history. Dictée’s hybrid form allows it to experiment with the lyric and epic traditions, challenging their forms to adequately reflect the lived experience of oppressed women. Dictée’s hybridity is but one aspect of its interrogation of literary form and language; the text also plays with grammar, specifically pronouns, to depict a genealogy of female voices as they relate to …

Estimation Of The Mechanical Properties Of South Carolina Timber Piles Using Non-Destructive Evaluation Methods And Experimentally-Informed Models, Aashish Sapkota

All Theses

South Carolina has about 2,600 bridges that are supported by nearly 75,000 timber piles. They are increasingly vulnerable to biological decay, cracking and impact damages after decades of service. Current inspection methods used by the South Carolina Department of Transportation (SCDOT), such as hammer sounding and awl probing, are labor-intensive and expensive. This study investigated non-destructive evaluation (NDE) methods, including micro-resistance drilling and stress wave timing, as alternatives for assessing timber pile condition.

Ten timber piles were collected from two South Carolina bridges, and their above-grade portions were cut into 40 specimens approximately 13 to 15 inches long. Specimens were …

Inferring Microstructure In Quaternary Sands Near Charleston, South Carolina Using Measured-To-Estimated Shear-Wave Velocity Ratio, Bikram Paudel

All Theses

The 1886 Charleston earthquake is one of the most destructive earthquakes in the history of the southeastern United States. It caused widespread damage and liquefaction, which is a phenomenon in which loose saturated granular soils lose their strength and behave like liquids during earthquakes. The main purpose of this research is to investigate how the earthquake changed the internal structure (termed as “microstructure”) of the sandy soil in the Charleston area. In general, when soil is deposited on a site and sits there for a long period of time, it develops a stronger structure through aging and cementation. To infer …

All Theses

This study evaluates how ramp meters, traffic lights installed on highway on-ramps, are used to reduce traffic on the West Coast of the United States, specifically in California, Oregon, and Washington. This research was conducted to better understand how ramp meters are planned and implemented, and to help government agencies manage traffic effectively without adding new highway lanes.

This study reviewed 129 public documents from federal, state, and local agencies to evaluate public involvement in ramp metering planning, concerns about the meters, costs and funding for the meters, and the meters’ design and implementation.

Demolition By Intent: Evaluating Charleston's Red X Placard Procedures, Enforcement Practices, And Communication Methods In The Loss Of Historic Structures, Jessica Stech

All Theses

This thesis examines whether the procedures, enforcement practices, and communication methods associated with the placement of Red X placards in Charleston, South Carolina, contribute to the demolition-by-intent of historic structures. Red X placards, also known as unsafe placards, are placed on the front façade of structurally unsafe structures by the Charleston Fire Department to inform first responders in the event of a fire or other emergency. Although these placards serve as a life-safety tool, they may influence how vacant structures are perceived by family or developer owners and the public.

Through using a qualitative approach, this thesis analyzes the outcomes …

Fluorescence-Based Quantification Of Hepatic Ldl Uptake And Donor Hepatocyte Engraftment Using Atto 700–Labeled Ldl, Victor Agustin Cortes Flores

All Theses

Familial hypercholesterolemia (FH) is an inherited disorder characterized by elevated low-density lipoprotein cholesterol (LDL-C) that increases the risk of premature atherosclerotic cardiovascular disease. In severe FH, including low-density lipoprotein receptor (LDLR), hepatic LDL clearance is profoundly impaired and many lipid lowering treatment strategies have limited effectiveness. Current advances in ex vivo CRISPR–Cas9 hepatocyte gene editing in vivo and ex vivo approaches for treatment of FH are under development.

However, a central barrier to translation is the ability to quantitatively measure the percentage of healthy gen edited hepatocytes in the liver while simultaneously assessing functional hepatic LDL handling. This thesis establishes …

Beyond The Interface: Human Perceptions Of Generative-Ai Chatbots As Conversational Partners, Browning W.E. Blair

All Theses

Generative AI (gen-AI) chatbots are becoming embedded in everyday communicative life, yet it remains unclear whether users perceive these systems as socially reciprocative conversational partners. Therefore, this study examines how young adults understand and interact with gen-AI chatbots, focusing on perceptions of conversational partnership, anthropomorphism, politeness, discomfort, and technical understanding. Guided by the CASA framework, Media Equation Theory, and the uncanny valley hypothesis, this study employed four semi-structured, online focus groups with 15 undergraduate students and recent college graduates in the United States. Findings indicate that participants did not broadly perceive gen-AI chatbots as conversational partners in the interpersonal sense. …

The "Confidential Whispers" Of Charles Francis Adams From His Teens Through Marriage At Age 22, Mitchell Jay Freedman

History ETDs

The early diaries and letters of Charles Francis Adams (1807-1886) reveal, contrary to previous scholarship, a passionate and sensitive young man engaged in multiple social activities with male and female friends and family, as well as enjoying licentious and respectful personal relationships with women. CFA was strategic with whom he was friendly or reserved, rooted in his hostility towards “hangers-on” and “hypocrites.” CFA also read widely both fiction and non-fiction with an affected sensitivity consistent with his desire for a literary-oriented life, the latter most reflected in his later curating his forebears’ papers. CFA’s early life experiences led CFA to …

The Prevalence Of Amenorrhea In Relation To Red-S Syndrome Among Various Sports In Collegiate Female Athletes, Ruby S. Holland, Marilou D. Shreve

The Eleanor Mann School of Nursing Undergraduate Honors Theses

Athletes that compete in high-intensity sports or without adequate caloric intake, are at risk for low energy expenditure which may disrupt hormonal balance. As development of RED-S is a well-established risk factor for amenorrhea, early detection and correction is crucial to prevent long term health consequences.

Purpose: The purpose of this research is to explore if there is a correlation between RED-S score and amenorrhea in female athletes.

Methods: An online survey was distributed to approximately 220 female athletes at the University of Arkansas using Qualtrics. The 69-question …

Effects Of Beaver Dams On Components Of Riverscape Health And Biodiversity In The Great Basin, Cashe C. Rasmussen

All Graduate Theses and Dissertations, Fall 2023 to Present

Networks of rivers and their floodplains (i.e., low-lying areas adjacent to rivers and streams that could plausibly flood) have been degraded, reducing the availability of freshwater and habitat for people and wildlife. Therefore, land managers are pursuing cost-effective restoration strategies, including partnering with beavers (Castor canadensis), to promote the health of these ecosystems and associated benefits. However, our understanding of beaver-mediated restoration benefits remains incomplete. Here, we compared locations along streams with and without beaver dams to measure the benefits of beavers in the Great Basin of the Western United States. We measured the effects of beaver dams …

Mechanisms Of Bacterial Glucokinase Inactivation Through Site-Specific Lysine Modification And Chemical Inhibition, Joseph Robert Will Andrews

Graduate Theses and Dissertations

Glycolysis and related metabolic pathways are controlled by various post-translational modifications (PTMs) that affect enzyme activity and metabolic flow. In E. coli, glucokinase (GLK) sits at the crossroads of glycolysis and the pentose phosphate pathway and carries out the first committed step of glycolysis: ATP-dependent phosphorylation of glucose. While it's known that glucose binding causes GLK to close its domains, how phosphate binding, lysine modification, and small-molecule inhibitors regulate GLK's shape and function is still not fully understood. Here, I combine structural biochemistry and enzymology to figure out how phosphate binding, specific mutations, and chemical inhibitors affect E. coli GLK. …

An Evaluation Of Leading Indicators In The Construction Industry And Their Relationship With Incident Rates, Kitti Miller Whalen

All-Inclusive List of Electronic Theses and Dissertations

Improving safety programs has been a focus of organizations for decades. Historically, focus has been directed towards lagging indicators such as recordable incident rates and experience modification rate (EMR). While these remain beneficial, they are only one component of the broader framework. In recent years, companies have started to examine what occurs prior to an incident, which are known as leading indicators. The research into leading indicators is promising, however research into the area is limited. The focus of this study is to identify which leading indicators are most strongly associated with improved incident rates in the construction industry specifically. …

Responsive Rigor And Strategic Care: Faculty Praxis For Holistic Student Success In The Community College, Jennifer Kelley

Library Scholarship

This qualitative study examines how community college faculty conceptualize, communicate, and enact academic rigor and care in their teaching practice. While post-pandemic debates have positioned rigor and care as opposing forces—evident in the "Rigor Wars" that framed care as performative laxity and rigor as gatekeeping—community college faculty successfully integrate these practices to support holistic student success. This research addresses critical gaps in higher education scholarship, which has studied rigor and care separately, focused primarily on four-year institutions, and overlooked faculty perspectives on how integration occurs in practice. Drawing on a single-case study of 38 faculty members at a large Midwestern …

Gender Identity, Political Alignment, And Views On “Man Or Bear” Trend Among Uconn Undergraduate Students, Erin Tumminello

Honors Scholar Theses

The “Man or Bear” debate, which became wildly popular online in 2024, asks whether someone would prefer encountering a random man or a random bear if alone in the woods. This question is meant to spark conversations around sexual and gender-based violence, and it created considerable discourse. Upon an exploration of the literature, findings include the fact that sexual violence often goes underreported among survivors, and that support of hegemonic masculinity and conservatism among men are associated with lower support for survivors. This study is meant to expand upon these findings, and to examine the ways in which gender identity …

Collaboration And Betrayal: Pius Xi And A Changing World, Nathan B. Higgins

Honors Scholar Theses

From the negotiations over the 1929 Lateran Accords to the start of World War II in 1939, the Holy See delicately navigated a turbulent diplomatic period. In the preceding century, the Catholic Church saw much of its temporal power decline as European states became more secular, and the pope lost the Papal States during the Risorgimento. Amid the decline in station, the rise of atheistic communism in Russia, Mexico, and Spain posed an existential to the Church, which Pope Pius XI would challenge during his pontificate. To confront this threat, he would work alongside Fascist Italy and Nazi Germany …

The insurance sector will be greatly affected as AI will simplify and automate many processes, resulting in higher accuracy while using fewer company resources. Some key areas of insurance that will be impacted include sales and customer service, underwriting and pricing, claims, fraud detection, risk prevention, and actuarial analysis. However, to be …

Promoting Effective Decision-Making Skills In High School Students, Jasmine Quiroz-Piceno

Capstone Projects and Master's Theses

Many high school students face challenges in academic decision-making. Without support in developing academic decision-making skills, they may lack the skills to recognize opportunities and make poor choices that could affect their educational trajectory. When these students learn to recognize and manage psychological and emotional responses in decision making, they may be better able to make clear and confident decisions about their education and future career. Therefore, I have created a one-day workshop to teach decision-making skills for high school students at Pajaro Valley High School in Watsonville, California.
