Philsongs: A Study Of Campfire Music Performed At Scouting America’S Philmont Scout Ranch (2014 To 2021), Ellyn Rager

Theses and Dissertations--Music

This dissertation focuses on Philmont Scout Ranch, a national Scouting America high adventure base in New Mexico and the largest youth camp in the world, arguing that music at Philmont serves as a cultural force that fosters an intensive communal bond among staff and campers by blending participatory and presentational music-making practices, while producing and reinforcing memories of Philmont through interpretive performances that negotiate the place’s historical narratives. Using surveys, interviews, and Thomas Turino’s framework of participatory and presentational music-making to interpret the author’s 100 hours of field recordings, this study examines aspects of Philmont’s musical habits between 2014 and …

From Financial Education To Financial Decisions: Evidence On College Financing, Personal Finance Behavior, And Student Attitudes, Dongwei Shi

University of Kentucky Doctoral Dissertations

I examine how financial education shapes students’ financial knowledge, college financing decisions, and longer-term financial behavior.

The first chapter studies whether taking high school financial education in Kentucky affects students’ college financing decisions using linked administrative records on high school course-taking and postsecondary financial aid. Using school-level financial education course availability as an instrument, the chapter evaluates whether exposure to financial education is associated with differences in student loan borrowing and receipt of need-based aid.

The second chapter examines whether exposure to state high school financial education mandates improves financial literacy and longer-term personal finance behavior among U.S. adults. Using …

Investigation Of Genx Exposure To Pathways Associated With Colorectal Cancer Risk, Emily J. Ferguson

Theses and Dissertations--Toxicology and Cancer Biology

Per- and polyfluoroalkyl substances (PFAS) are persistent environmental contaminants widely detected in drinking water and food sources, resulting in chronic human exposure. Among these compounds, hexafluoropropylene oxide dimer acid (HFPO-DA), commonly known as GenX, has been introduced as a short-chain replacement for legacy PFAS such as perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA). Although GenX is believed to be a safer alternative, emerging research suggests it can still affect human health.

Colorectal cancer (CRC) is the third most commonly diagnosed cancer and the second leading cause of cancer-related death in the United States, highlighting the need to better understand environmental …

Reep2-Driven Pro-Metastatic Secretion Promotes Lung Cancer Progression, Oluwafunminiyi E. Obaleye

Theses and Dissertations--Toxicology and Cancer Biology

Membrane trafficking plays a critical role in cellular function and is frequently dysregulated in cancer to promote metastasis. In lung adenocarcinoma (LUAD), the epithelial-to-mesenchymal transition (EMT) activating transcription factor, ZEB1, drives a pro-metastatic membrane trafficking program; however, the underlying molecular mechanisms remain poorly understood. Using a CRISPR interference (CRISPRi) in vivo screen of 2,099 membrane trafficking regulators in a syngeneic mouse model of EMT-driven LUAD, we identified REEP2 — an endoplasmic reticulum (ER) shaping protein — as a critical regulator of tumor progression. REEP2 mRNA expression correlates with poor prognosis, EMT signatures, and an immunosuppressive tumor microenvironment in LUAD patients. …

Klusty, Cole Corbett, Angelique D. Gonzalez, David A. Gutman, David W. Fardo, Adam D. Bachstetter, Cody Bumgardner, Margaret E. Flanagan, Peter T. Nelson

Sanders-Brown Center on Aging Faculty Publications

Alzheimer's disease neuropathological changes (ADNC)—operationalized with semi-quantitative parameters—represent the consensus-based gold standard for diagnostic evaluation of disease severity. Although useful, ADNC diagnostic frameworks have limitations, particularly in advanced disease stages where pathological severity varies widely within a given diagnostic category. Further, some individuals lacking cognitive impairment are inappropriately categorized as having severe ADNC. In this study, quantitative pathology metrics and alternative tissue sampling schemes were integrated with data about premortem cognitive status, in order to derive clinically informed neuropathologic diagnostic thresholds. Specific goals of the current study were to generate data-driven, standardized diagnostic cut-points, with the most severe stages of …

Designing and interpreting early phase trials of theranostic radiopharmaceuticals remains challenging because it is difficult to isolate effective levels of activity in enriched patient populations that would be worth following up in later-phase development. This study explores the known challenges and emerging opportunities for clinical research on patients with uterine cervical cancer. We identified eight randomized combination trials for advanced-stage uterine cervix cancer that were activated between 2011 and 2022 and tabulated their results to determine whether combinations were better than individual constituents and which suitable study population is best situated for the study of a new theranostic agent. In …

Artificial Intelligence Methods For Circadian Rhythm Recovery And Disease Identification From High-Dimensional Omics Data, Aram Ansary Ogholbake

Theses and Dissertations--Computer Science

High-throughput transcriptomic and proteomic technologies have enabled opportunities for studying biological processes and disease mechanisms. However, extracting meaningful biological information from these high-dimensional datasets remains challenging due to limited sample sizes, biological heterogeneity, measurement noise, and the absence of biological annotations. In particular, many molecular datasets lack temporal information required for circadian analysis, making the study of circadian rhythms difficult. Moreover, disease diagnosis and biomarker discovery from transcriptomic data often rely on complex machine learning models whose predictions are difficult to interpret and may not generalize well across independent datasets and experimental platforms. These limitations motivate the development of artificial …

Qualitative data included 34 reflective journal entries analyzed using reflexive thematic analysis, and quantitative data included multiple client outcome trajectories across several clinical measures compared descriptively with prototypical change trajectories derived from MFT-PRN datasets. Qualitative findings reflected a developmental progression from initial anxiety and performance concerns toward increased confidence, attunement, …

Goal-Driven Shared Control In Eeg-Based Brain Machine Interface For Freewill Reaching And Grasping With Movement Intention Detection And Goal Position Decoding, Bhoj Raj Thapa

Theses and Dissertations--Electrical and Computer Engineering

Upper limb motor impairments can severely limit a person’s ability to perform everyday reaching and grasping tasks. Electroencephalogram (EEG)-based brain machine interfaces (BMIs) offer a non-invasive approach for translating neural activity into control signals for assistive devices such as robotic arms. However, traditional EEG-based BMI studies have generally focused on externally cued paradigms, where both movement timing and target selection are specified by the experimenter rather than freely chosen by the user. In addition, shared control offers a practical framework for assistive BMI operation by dividing responsibility between the user and the intelligent robotic system. However, in many EEG-based shared …

Effect Of Environmental Conditions On German Cockroach (Blattella Germanica) Behavior And Survival, Allison Lopina

Theses and Dissertations--Entomology

German cockroaches (Blattella germanica L.) remain one of the most challenging indoor pests to manage, due to resistance to many commonly used insecticides, and necessary contact/interaction with common management tactics. As such, it is critical to fully understand their aggregation, movement, and longevity, such that treatments can be optimally placed to result in maximal efficacy. The first part of this study explored the effects of multiple factors (harborage width, harborage materials, heat, resource-harborage distance) on initial site selection, and how environmental modifications and infestation density impact harborage site switching. The second half of the study aimed to explore the …

Accelerator Based Fusion Reactor With Magnetic Mirror, Keh-Fei Liu

Physics and Astronomy Faculty Publications

We consider an implementation of the novel accelerator-based fusion reactor scheme using a setup in which ion and electron beams are injected into the end openings of an axisymmetric magnetic mirror. While the magnetic mirror ensures transverse confinement of the plasma, the injected beams contribute to axial confinement, thereby extending the overall plasma lifetime. The ion beam energy is initially set above the resonance region of the fusion reactions, allowing fusion to occur both via resonance and thermal mechanisms as the beam slows down to the plasma temperature. Beam energy loss (stopping power) contributes to plasma heating, offsetting radiative losses …

Emission-Line Diagnostics At Z ≳ 2: A Probe Of The Ionizing Spectrum And Α-Enhancement Beyond Cosmic Noon, Leonardo Clarke, Natalie Lam, Alice E. Shapley, Michael W. Topping, Gabriel B. Brammer, Ryan L. Sanders, Naveen Reddy, Shreya Karthikeyan

Physics and Astronomy Faculty Publications

We analyze several key rest-optical emission-line ratios in a sample of 828 galaxies as well as composite spectra from JADES DR3 in the range 1.4 <  z <  7. These emission-line ratios include: [O iii]λ5008/Hβ, [N ii]λ6585/Hα, [S ii]λλ6718, 6733/Hα, [O i]λ6302/Hα, O32, R23, Ne3O2, and RO2Ne3. We find evidence for a harder ionizing spectrum at z ∼ 3.5 compared to z ∼ 2 at fixed gas-phase metallicity, resulting in a pronounced shift in the star-forming galaxy locus on the [N ii]/Hα Baldwin-Phillips-Terlevich (BPT) diagram and the O32 versus R23 diagram.

Characterization Of Full Bridge Strain Transducers For Haulage Equipment Payload Distribution Monitoring, Jean-Pierre Strydom, Steven Schafrik, Zacharias Agioutantis, Matthew J. Beck, Joseph Sottile

Mining Engineering Faculty Publications

Creating a dependable approach for identifying both the mass of a shuttle car and how material is distributed in it removes the need for equipment operators to manually engage the flight chain. The quantification of environmental and installation conditions and the extent of influence considering their combined contribution towards inaccurate or exclusive measurements are to that degree limited. This experimental study investigated how two different strain transducers—installed in a force-shunt configuration—respond to thermo-mechanical loads when used to determine load distribution and position. Initial observations indicated that thermal effects at the installation site contributed to measurement inaccuracies or exclusive readings. The …

Fiscal Decentralization, Foreign Capital, And Economic Development In Sub-Saharan Africa, Kwadwo D. Frempong

Theses and Dissertations--Public Policy and Administration

Economic development in Sub-Saharan Africa has been shaped by two transformative policy shifts: widespread fiscal decentralization reforms transferring revenue and expenditure authority to subnational governments, and the pursuit of foreign direct investment to supplement domestic capital. Despite the breadth of these reforms, their effectiveness in promoting sustainable economic development remains empirically contested. This dissertation examines three interconnected questions about fiscal governance and capital flows in Sub-Saharan Africa: what determines the extent to which governments decentralize fiscal authority; how county fiscal composition and revenue autonomy shape subnational economic performance; and how foreign direct investment interacts with domestic investment and growth.
