Three-Photon Rydberg Eit Lineshape Analysis In Rubidium, Jackson Lake

Honors Theses

Electromagnetically Induced Transparency detection of high-lying Rydberg states in room-temperature rubidium vapor was investigated using a four state ladder-type excitation scheme with light provided by three External Cavity Diode Lasers (ECDLs) at 780 nm, 776 nm, and 1266 nm. This detection technique was studied by characterizing the lineshape parameters of the EIT transmission peak, specifically the height, width and area of the transparency window as functions of the dressing and coupling laser powers. With the goal of characterizing the linewidth of the transmission signal, a confocal etalon was built and implemented in the optical setup to perform frequency calibration of …

Enumerating Matrices Of A Given Order Over Finite Fields, Thor Richard Gabrielsen

Honors Theses

This thesis derives a generating function that describes the matrices of a given multiplicative order over finite fields of a given order assuming that the order of a field is not a divisor of the desired order of the matrix. This is done by using the power series known as the cycle index derived from the rational canonical form. This index can be factored, and using the fact that the minimal polynomial divides some polynomial of the form x^k − 1 we can show that the minimal polynomial is squarefree. This sufficiently restricts the form of the rational canonical form …

Brewing Resilience: Cooperatives, Micro-Mills, And The Quest For Survival In Costa Rica's Changing Coffee Landscape, Leila N. Iredell

Honors Theses

This thesis examines how different organizational models in Costa Rica's coffee sector shape producers’ ability to capture value, build resilience, and sustain rural livelihoods in a rapidly changing global market. In comparing traditional cooperatives and new micro-mills, I examine specifically how control over the value chain, access to markets, and social infrastructure differ across models and what these differences mean for the farmers who depend on them. This project analyzes how the collapse of international price agreements and decades of market volatility drove producers toward new strategies, from independent processing and direct trade to coffee tourism. Costa Rica stands as …

Blood And Belonging: Remembering Massacres Of The American West In The Twentieth Century, Mountain Meadows And Sand Creek, Kenzie Burns

Honors Theses

The late nineteenth and early twentieth centuries marked a turning point in mainstream America’s sense of national identity. A wave of nostalgia for the American Frontier enshrined the region’s idealized nineteenth-century past as myth. A key part of the story is romanticized violence—often depicted through cultural imagery of cowboys, gunfights, and battles with American Indians. This project seeks to understand more about how violence is represented in the cultural memory of the American Western past. Within the past twenty years, scholars of the American West have begun to incorporate the study of memory into their scholarship, frequently with how cultural …

Borrowed Mantles: Neoclassicism, Theology, And The Construction Of Authority In Phillis Wheatley-Peters, Zoe N. Lament

Honors Theses

This thesis examines how Phillis Wheatley-Peters established literary and intellectual authority within an eighteenth-century world that questioned both her authorship and her intellectual capability as an enslaved Black woman. Rather than focusing on the external validation provided by the prefatory materials to Poems on Various Subjects, Religious and Moral (1773), this study argues that Wheatley-Peters constructs authority through the poetry itself. Specifically, it explores how her use of neoclassical poetic conventions alongside Christian theological language functions to establish credibility and strengthen her moral and intellectual arguments.

Through close readings of poems including "On Being Brought from Africa to America" and …

Analyzing Rydberg Atoms Of Rubidium At Room Temperature: Applying Electromagnetically Induced Transparency, Bridger Stiles

Honors Theses

This thesis describes an experimental exploration of electromagnetically induced transparency (EIT) in atoms of 85Rb using a new MOGLabs external cavity diode laser. A two-step ladder technique of EIT was applied using a 5S_1/2→5P_3/2 probe transition and 5P_3/2→nD_5/2 coupling transitions. Significant apparatus tuning was done, including developing a reliable procedure of regulating frequency and scanning the coupling laser over a sufficient mode-hop free range. A Doppler-reduced technique was applied by counter-propagating the probe and coupling beams through the Rb vapor cell. EIT signals were collected at various probe and coupling laser powers to analyze changes in signal size and linewidth. …

Between Commodity And Culture: Tea Advertising As A Site Of Imperial Ideology And Anti-Colonial Resistance In India, Sydney Pascal

Honors Theses

Between the late nineteenth century and Indian independence in 1947, tea advertising became a key site through which imperial authority and Indian nationalism were negotiated. Drawing on advertisements, trade journals, and visual marketing campaigns produced from the 1880s through the 1950s, this honors thesis argues that tea advertising was a cultural and political mechanism through which the British Empire attempted to normalize imperial consumption and legitimize colonial authority. British campaigns framed tea as modern and routine while obscuring the exploitative labor systems and landscape transformations that sustained plantation production in Assam. As nationalist movements expanded in the early twentieth century, …

Rooted: Nature, Belonging, & Occupational Justice, Grace Barnett

OTD 721: Cultural Responsiveness & Occupation

This zine was created for OTD 721: Cultural Responsiveness & Occupation. I recognize that I cannot speak or represent all cultures, but I approach this work with cultural curiosity and a commitment to learning. I was intentional about not speaking for others, but instead reflecting on my own understanding, experiences, and using scholarly articles.

I chose this topic because environments have a powerful influence on occupational participation. Nature, in particular, has been a source of healing, grounding, and comfort in my own life, which shaped my interest in exploring this connection more deeply though an occupational lens.

One of the …

Stitched With Purpose, Abigail Gooler

OTD 721: Cultural Responsiveness & Occupation

I chose this topic for this zine because fiber arts have become a meaningful part of my life. What began as a hobby during the COVID pandemic has grown into a way for me to manage stress, find purpose through creating, and build a small business.

This project deepened my understanding of occupational justice and the way that occupations are shaped by culture, gender, access, and social determinants of health. It challenged me to view what is an everyday occupation for me as culturally significant and, at times, political.

This project also reminded me of the privilege I have to …

Girl, Just Shut Up & Take An Advil: A Zine About Periods, Participation, And Why We All Became Experts At The Tampon-To-Sleeve Transfer, Alexa Ford

OTD 721: Cultural Responsiveness & Occupation

Like many people, I learned early on that menstruation was something to manage quietly. I learned how to check for stains without making it obvious. I learned how to strategically tie a sweatshirt around my waist. I learned that asking, "Do you have one?" across a public restroom often resullts in an immediate and enthusiastic, "Yes, girl. What do you need?" Over time, I realized these weren't just funny shared experiences. They reflected something bigger. The silence. The stigma. The expectation that people should function through discomfort without complaint.

As I've learned more through occupational therapy, I've started to understand …

The Effects Of Inadequate Training On Knowledge Management Systems: Retention Crisis Of Captains In The United States Army, Lexis R. Grudzinski

Theses and Dissertations

This research explores the relationship between the United States Army’s communication strategy in knowledge management for officers and the desires of captains to continue serving beyond their service obligation. Amidst the current retention crisis (Winkie, 2023) at the captain rank, blame often falls on factors outside of the Army’s control. This research, however, seeks to investigate a factor within the Army’s control and offer workable solutions.

For this research, we will use the common definition of knowledge management (KM): the process of creating, capturing, and organizing knowledge within an organization in a way that improves efficiency. KM includes both explicit …

Timbral Effects Of 3d Printing Brass Wind Musical Instruments: A Comparison Between Traditional And 3d Printed Construction, Cole K. Zelman

Theses and Dissertations

This study explores the timbral effects that manufacturing wind instruments from thermoplastics (via 3D printing) has in comparison to traditionally made instruments. The project mainly focuses on the individual properties of different thermoplastics in comparison to traditional materials like brass. The instrument tested is a C bugle for a simple example of a brass wind instrument and is compared directly against the traditional brass construction. Results employ spectral centroid, spectrograms, and professional subjective analysis to compare the different thermoplastic test samples to the control brass bugle.

Ceo's Influence On Top Management Team's Employee Engagement: A Qualitative Study, Wafa Damlaj, Matthew Hurtienne, Laura Hurtienne

Human Resource Development Student Publications and Presentations

This study explores how chief executives officers (CEOs) influence top management team (TMT) members' employee engagement. Using a constructivist phenomenological approach, the research examines ways CEOs shape TMT's employee engagement. Fifteen TMT professionals participated in semi-structured interviews, and the data were analyzed through a three-step coding process: open coding to identify key concepts, axial coding to refine categories by examining relationships, and thematic coding to organize the data into central themes. Findings revealed that CEOs influence TMT's employee engagement by addressing needs at three levels: individual, team, and organizational. Each level of needs aligns with specific CEO leadership styles and …

Bridging The Social Class Capital Gap: A Psychological Intervention In The Newcomer Adjustment Context, Grace J. H. Lim, Marko Pitesa

Research Collection Lee Kong Chian School Of Business

Motivated by observations that workers from lower social class backgrounds often experience lower career outcomes even after securing desirable jobs, we adopted an abductive approach—combining theory (the newcomer personal capital framework) with qualitative evidence from open‐ended accounts (Study 1)—to identify three challenges these workers face after joining organizations as newcomers: limited cultural capital (i.e., institutional knowledge), lower social capital (i.e., social self‐efficacy), and lower psychological capital (i.e., distress tolerance). Furthermore, in Study 1, we developed and tested a psychological intervention targeting these challenges and found that it effectively addressed them. In Studies 2 and 3, both preregistered field experiments, we …

Policy Uncertainty Reduces Green Innovation, Mengyu Wang, Jeffrey Wurgler, Hong Zhang

Research Collection Lee Kong Chian School Of Business

Policy uncertainty can undermine the power of government subsidies to stimulate environmentally friendly research and development. We show that Chinese firms’ green R&D falls as the uncertainty of environmental subsidies rises: Exogenous, weather-driven air pollution variability induces subsidies to fluctuate, and firms in areas with high weather-driven subsidy variability undertake less green R&D and hire fewer technical employees, controlling for the average level of subsidies. Heavy emitters and environmental technology firms are more affected. The results also illustrate how policy uncertainty can arise when policymakers are influenced by conditions that are salient but with causes that are difficult to disentangle.

Fluid Agency In Ai Systems: A Case For Functional Equivalence In Copyright, Patent, And Tort, Anirban Mukherjee, Hannah H. Chang

Research Collection Lee Kong Chian School Of Business

Modern Artificial Intelligence (AI) systems exhibit fluid agency in multi-step workflows: lacking human-like consciousness or culpability, yet they display behavior that is (i) stochastic (probabilistic and path‑dependent), (ii) dynamic (co‑evolving with user interaction), and (iii) adaptive (able to reorient across contexts). These properties generate valuable outputs but collapse attribution, irreducibly entangling human and machine inputs. Doctrines that assume traceable provenance—authorship, inventorship, and liability—fracture under this unmappability, yielding ownership gaps and moral “crumple zones.”This Article argues that only functional equivalence stabilizes doctrine under unmappability: Where provenance is indeterminate, legal frameworks should treat human and AI contributions as equivalent for allocating rights …

Bariatric Surgery Impacts Immune Cell Metabolism And Function Dependent On Metabolic Status, Samantha N. Hart

University of Kentucky Doctoral Dissertations

Type 2 Diabetes (T2D), one of the top ten causes of death worldwide, is fueled by chronic inflammation. T2D is considered a metabolic disease, and there is a great push to target metabolic and associated inflammatory pathways to ameliorate the disease & its comorbidities i.e., obesity and cardiovascular disease. Thus far, clinical trials of anti-inflammatory drugs have had modest impacts on T2D and have not led to changes in clinical practice. This may in part be due to a gap in knowledge in the mechanism(s) driving obesity-associated chronic inflammation. I posit that metabolic abnormalities in immune cells in those with …

Promptable Segmentation For Adaptive And Data-Efficient Medical Image Analysis, Tyler Ward

University of Kentucky Doctoral Dissertations

Image segmentation is a fundamental task in computer vision. While segmentation models have traditionally been trained in a fully-supervised manner, recent approaches have leveraged large-scale pre-training and prompting mechanisms to great effect. However, the performance of such approaches often degrades when applied to domain-specific tasks like medical image analysis. A major reason for this lies is that these models are trained on large, labeled datasets of natural images, which have drastically different characteristics compared to medical images, limiting the generalizability of the methods when applied to medical data. This dissertation presents several data-efficient, adaptive, and promptable medical image segmentation models. …

Multiscale Modeling Of The Thermomechanical Behavior Of Polymeric And Molecular Organic Semiconductors, Kehinde H. Fagbohungbe

University of Kentucky Doctoral Dissertations

Organic semiconductors, derived from π-conjugated polymers and molecules, enable the development of deformable, stretchable and flexible electronics due to their tunable redox, optical, electronic and mechanical properties. However, an informed understanding of how multi-scale morphological characteristics of the polymeric and molecular semiconductors influence bulk properties that contribute to electronic and optical performance, especially under operational thermal and mechanical stresses, remains incomplete. This lack of understanding poses a challenge to scalability and commercialization of organic electronics. This dissertation develops and deploys computational modeling approaches, particularly atomistic molecular dynamics (MD) simulations, to investigate the multiscale morphological behavior of these synthetic semiconducting materials …

A Nonlocal Lattice Particle Method For Modeling Hcp Polycrystalline Solids, Di Liu

University of Kentucky Doctoral Dissertations

Polycrystalline materials, composed of individual grains with varying grain size, shape, and crystallographic orientation are widely used in various engineering and industrial applications. Conventional applications of polycrystalline materials rely on the macroscopic performance, and the microstructural features are usually homogenized out. With the advancement of modern technologies and improvement of characterization methods, polycrystalline materials find their applications in meso- and micro-scale systems. At these length scales, the microscopic features including grain boundary characteristics significantly affect the material physical responses. As a result, the conventional continuum mechanics models become problematic, especially for material failure problems where the microstructural features play dominant …

Growth In The Margins: Field Measured Protein Metabolism Rates In The Common Limpet, Patella Vulgata, Ignacio A. Cienfuegos, Benjamin J. Ciotti, Richard A. Billington, Paul A. Sutton, Keiron P.P. Fraser

School of Biological and Marine Sciences

Intertidal shores are characterised by a high variability in abiotic conditions, resulting in marked daily, tidal, seasonal and vertical differences in stress conditions, yet our ability to understand the consequences for key physiological processes at corresponding scales are limited. In particular, no previous studies have directly measured protein metabolism, the key process underpinning animal growth, in the field, in any organism. We measured whole-animal (SGR) and tissue (TSGR) mass growth, protein metabolism (synthesis (k_s), degradation (k_d) and growth (k_g)), RNA to protein ratios and oxidative stress in Patella vulgata in the field every season …

Gelatinous Zooplankton As Indicators In The Kunming Montreal Global Biodiversity Framework, John Terenzini, Laura J. Falkenberg, Sanae Chiba, Matthew Faith, Robert Puschendorf, Abigail Mcquatters-Gollop

School of Biological and Marine Sciences

Global biodiversity frameworks require robust, representative indicators to effectively track progress towards conservation targets. Spatial and temporal gaps in global marine biodiversity datasets, however, and a limited number of marine biodiversity indicators, limit our ability to effectively manage marine ecosystems. Despite the ecological and socio-economic significance of marine ecosystems, they remain underrepresented in current indicator suites, particularly in the recently adopted Kunming-Montreal Global Biodiversity Framework (KMGBF). Gelatinous zooplankton (GZ), a key yet often overlooked component of marine ecosystems, have the potential to strengthen biodiversity assessments through their responsiveness to environmental change and impacts on several contributions of the ocean to …

Effects Of Emerald Ash Borer Specific Gene Silencing Using Rna Interference On Soil Communities, Faith S. Boa

University of Kentucky Master's Theses

The emerald ash borer (EAB) (Agrilus planipennis Fairmaire) is an invasive wood- boring beetle from Asia that primarily feeds on ash trees (Fraxinus spp.). Since its invasion of North America, EAB threatens the functional extinction of ash with damages and management costs projected to reach $900 million by 2054. Current management strategies have been insufficient to prevent EAB’s spread, highlighting the need to advance innovative approaches like RNAi, which has demonstrated efficacy against EAB in laboratory and greenhouse trials. Double-stranded RNA targeting heat shock 70-kDa protein (hsp) induces EAB mortality, systematically disperses and persists in …
