The Ecological Consequences Of Horizontal Transmission Of Symbionts, Bibek Singh Parajuli

Biology Dissertations

Most multicellular organisms depend on their microbial symbionts for various functions, such as digestion, nutrient supplementation, pesticide degradation, and defense. While many insects acquire their symbionts vertically from their parents, thousands of species of true bugs (Hemiptera) across different families acquire their microbial symbiont, Caballeronia, from the environment each generation. Acquiring symbionts from the environment (horizontal transmission) has various ecological consequences for the host. In this study, I used the bug-Caballeronia model 1) to understand whether the free-living symbionts benefit from association with multicellular hosts, 2) to evaluate whether host specialization on symbiont strains varies across taxonomic levels, …

Effects Of Fermented Soybean Products On The Human Gut Microbiome, Microbial Metabolism, And Host Physiology, Shannon Moncier

Biology Dissertations

Fermented soybean products (FSPs) contain soybean-derived substrates, fermentation-associated microorganisms, and bioactive compounds that may interact with the human gut microbiome and host physiology. However, despite the growing interest in FSPs, longitudinal human studies specifically evaluating traditional Korean-FSPs (K-FSPs), particularly among United States-based populations, remain limited. The objective of this work was to evaluate the effects of three K-FSPs, including Cheonggukjang, Gochujang, and Doenjang, on host physiological responses, gut microbial community structure, predicted microbial functional potential, and fecal butyrate responses in healthy adults. Three independent dietary intervention cohorts were conducted using FSP formulations produced either by traditional artisan methods (Product A) …

Neuromodulation Of Pain-Related Network Dynamics: Effects Of Electroconvulsive Stimulation On Local Field Potential Activity In A Formalin Pain Model, Diana A. Ibarra

Psychology Theses

Electroconvulsive therapy (ECT) is an established neuromodulatory intervention used to treat severe psychiatric conditions and is known to briefly affect memory function. Given that chronic pain affects millions and often leads to opioid dependence, ECT has been investigated to treat chronic pain. This study examined how electroconvulsive stimulation (ECS), the experimental equivalent of ECT used in animal models, alters or reduces pain-related brain neural activity associated with maladaptive pain-related memory circuit representations. The hypothesis is that ECS will disrupt or reduce neural activity associated with pain-related memory circuits, potentially revealing neural mechanisms that link pain and memory circuits through …

Examining The Effectiveness Of Icu Diaries In Reducing Post–Intensive Care Syndrome (Pics) Psychological Symptoms: A Rapid Review Of United States–Based Studies, Lananh Tran

Honors Undergraduate Theses

Background: The growing recognition of Post-Intensive Care Syndrome (PICS) has prompted investigation into interventions, such as ICU diaries, to mitigate the long-term psychological effects of PICS. Intensive care unit (ICU) diaries – journals written by clinicians and loved ones during an ICU admission – are a tool that can help patients reconstruct the events of their critical care experience. Entries in the diary may include clinical updates, explanation of treatments, and encouraging words from loved ones or staff. Previous research in European countries found ICU diaries may be effective in reducing psychological effects post ICU admission.

Research question: The aim …

The Anonymous Officer, Shawn E. Fields

Faculty Scholarship

(Forthcoming 2026) Masked, plainclothes immigration agents in unmarked vans have terrorized communities in Chicago, Los Angeles, Minneapolis, and beyond. The indiscriminate violence committed by federal officers who at times appear indistinguishable from paramilitary units has forced immigrants into hiding and left lawmakers scrambling to address a growing and largely legal anonymity crisis in law enforcement. This Article explores the undertheorized implications of anonymous law enforcement, situating the rise of masked policing within a larger project of democratic retrogression and executive aggrandizement. Anonymity in policing and immigration enforcement frustrates core democratic norms of transparency, accountability, and legitimacy, providing the opacity needed …

Trump's War On Diversity, Equity, And Inclusion, Nancy C. Marcus

Faculty Scholarship

Among the many head-spinning developments that have occurred from the first days of President Trump’s second presidency are his attacks on DEI (diversity, equity, and inclusion), including anti-DEI edicts targeting educational institutions. This article provides a chronology and analysis of the early 2025 Trump administration’s attacks on DEI targeting schools nationwide, the resulting harms, and responses thereto, including litigation. A discernible refrain in the early litigation challenging President Trump’s anti-DEI attacks targeting educational institutions across the country has been how those attacks cross a clear constitutional line: the prohibition of unconstitutionally obscure governmental mandates. At its core, the void-for-vagueness doctrine …

Rewards That Resonate- How Incentivized Online Reviews Shape Customer Loyalty And Review Outcomes, Sameeha Khizindar

Marketing Dissertations

In today’s competitive marketplace, online reviews have become a central feature of consumer decision-making and business strategy. Research consistently documents that online reviews have a positive impact on outcomes such as review volume and product sales, underscoring their critical role in shaping firm performance. However, the majority of consumers do not voluntarily write reviews, posing a challenge for companies that rely on user-generated content. To address this issue, companies often offer incentives to motivate customers to write reviews. Despite their widespread use, research on their impact remains limited. This dissertation is comprised of two essays that examine the impact of …

End-To-End Development And Experimental Validation Of A 1/10-Scale Autonomous Vehicle, Rikkin Pankaj Panchal

Electrical Engineering Theses

To streamline platform development, an AI assisted annotation framework automates dataset generation, significantly reducing manual labor while improving training data quality. The system perception stack features a reinforcement learning guided online multi camera calibration framework that enables adaptive surround view stitching without the need for offline recalibration. This is paired with robust lane …

Mechanisms Of Vascular Acetylcholine Reactivity In Cardiac Hypertrophy: The Role Of Calcium Channels And Endothelial Pi3k/Akt/Enos Signaling In Rats, Rebwar Tahir Mohammed, Ismail Mustafa Maulood

Polytechnic Journal

Cardiac hypertrophy alters vascular function and promotes myocardial damage via oxidative stress and inflammation, with calcium channels and the PI3K/AKT/eNOS signalling pathway being pivotal in vascular reactivity. Nonetheless, their precise role in acetylcholine (ACh)-mediated vascular responses during hypertrophy remains little elucidated. The study aims to investigate calcium channel functions and endothelial PI3K/AKT/eNOS signalling in modulating vascular reactivity in a rat model of cardiac hypertrophy. Aortic rings from control and ISO-treated rats were mounted in organ baths. Cumulative ACh dose–response curves (DRC) were obtained at baseline and after preincubation with Nω-nitro-L-arginine methyl ester (L-NAME), a nitric oxide synthase (NOS) blocker, PI3K …

Elevating Teacher Agency In School Decision-Making Through Trust-Building: Applying Appreciative Inquiry Within A Mixed Methods Action Research Framework, Alison S. Bellamy

University of Kentucky Doctoral Dissertations

This mixed methods action research (MMAR) study examined how Appreciative Inquiry–based professional learning influenced relational trust, teacher voice, and teacher agency in elementary school decision-making within New Hanover County Schools. Grounded in Teacher Agency Theory, Distributed Leadership Theory, and Appreciative Inquiry, the study addressed the gap between teachers’ perceptions of trust and their opportunities to influence school-level decisions. The study was conducted across three mid-quintile elementary schools using a concurrent QUAN–QUAL design. Quantitative data was collected through pre- and post-intervention relational trust surveys. Qualitative data included focus groups, participant reflections, field notes, and collaborative dialogue from two professional learning sessions …

Uncovering The Mechanism Of Reep2-Mediated Emt-Driven Membrane Trafficking In Lung Adenocarcinoma, Kevin Fulp

Theses and Dissertations--Toxicology and Cancer Biology

Membrane trafficking is frequently disrupted during cancer progression, and the underlying mechanisms remain largely unknown. Currently, no effective drugs target dysregulated membrane trafficking for cancer treatment. Recent evidence has demonstrated that epithelial-to-mesenchymal transition (EMT) in lung adenocarcinoma (LUAD) employs a membrane trafficking program to coordinate cancer cell invasion and immunosuppression. To further dissect the pro-tumorigenic membrane trafficking program, we initiated an in vivo CRISPRi screen to assess more than 2,000 membrane trafficking-related genes in a syngeneic mouse LUAD model. We identified REEP2, an endoplasmic reticulum (ER) shaping protein, as a novel regulator of EMT-driven membrane trafficking. High REEP2 expression is …
