“Being Treated As The Expert:” A Blueprint For A Community Advisory Board Approach To Elevate The Voice Of People With Living Experience With Substance Use In Academic Research, Trevor Moffitt, Survivors Union Of The Bluegrass, Bryson Henson, April M. Young, Sharon L. Walsh, Rachel Vickers-Smith, Junior Cruz, Jeremy Byard, Brook West, Amanda Fallin-Bennett

Nursing Faculty Publications

Introduction: Researchers have traditionally engaged Community Advisory Boards (CABs) to meaningfully involve community members in the research process. However, CABs are often formed only after a grant is funded, leading to criticisms of functioning merely as “ethical approvers.” For substance use researchers, the inclusion of people with living experience (PWLE; current experience with drug use) across all stages of research is especially important as they have historically been the experts in the needs of their community.   Methods: In response to this need for community engagement in research, the University of Kentucky, in partnership with a local recovery community center (RCC; …

Coalition Building And Citizen Science For Radon Risk Reduction, Stacy Stanifer, Kathy Rademacher, Whitney Sedio, Naomi Cheek, David Gross, Caitlyn Curtis, Amanda Thaxton-Wiggins, Mary Kay Rayens, Ellen J. Hahn

Nursing Faculty Publications

We evaluated the implementation of local coalitions led in partnership with citizen scientists, community-based organizations, and public libraries in four rural communities to lower exposure to radon in the home. The objectives were to (1) describe the Reach-Effectiveness-Adoption-Implementation-Maintenance (RE-AIM) of four radon coalitions, and (2) compare RE-AIM factors among citizen scientists who participated in the coalitions and those who did not. A larger community-engaged research project embedded coalition building using a citizen science approach. Three of the four coalitions focused on health and wellness more broadly (18–34 members); one focused solely on radon (10 members). Coalition membership and activities varied …

Financial Status, Fatalism, And Self-Care Of Cardiovascular Disease Risk Factors Among Rural Adults Living In Socioeconomically Distressed Areas, Ashmita Thapa, Geunyeong Cha, Dustin Hodges, Jia-Rong Wu, Misook L. Chung, Martha J. Biddle, Jennifer L. Smith, Debra K. Moser

Nursing Faculty Publications

Purpose: Adults with fewer financial resources often have poor self-care. Rural dwellers commonly have fewer financial resources than urban dwellers and are often stereotyped as fatalistic about health. We examined whether fatalism mediates the association of financial status with cardiovascular disease (CVD) self-care in rural adults in economically distressed areas. We hypothesized that those with fewer financial resources would have poorer self-care, and fatalism would mediate this relationship.

Methods: We enrolled 1,122 adults (53 ± 15 years) at risk for CVD. Financial status was reflected by individuals’ perceptions of how well they made “ends meet” with their financial resources, fatalism …

The Impossible Motherhood: Education Accompanying Mothers (Peidu Mama) And Transnational Migration In China’S Global Era, Jingxue Zhang Dr.

Theses and Dissertations--Gender and Women's Studies

This dissertation examines transnational educational relocation as a gendered project of future making through the figure of Chinese educational accompanying mothers, or peidu mama, in Chiang Mai, Thailand, and the Greater Los Angeles area in the United States. It investigates how educational migration is organized through the intersection of affective governance, moralized motherhood, and unequal global conditions. It seeks to answer how transnational educational motherhood is represented in state-endorsed media and public discourse; how women narrate and justify educational relocation while negotiating the morally unstable label of peidu mama; how aspiration, risk, and the idea of “a better …

Engineering Plga Nanoparticle Size To Modulate Immune Responses After Spinal Cord Injury, Daniel J. Kolpek

University of Kentucky Doctoral Dissertations

Spinal cord injury is a severe and debilitating condition that often results in lifelong complications, including paralysis. Many of these chronic outcomes are driven by a sustained inflammatory response at the injury site, which limits tissue regeneration and functional recovery. As a result, therapeutic strategies that modulate this immune response have gained significant interest. Polymer based nanoparticle therapies have emerged as a promising approach due to their ability to interact with and influence immune cell behavior. Importantly, the physicochemical properties of nanoparticles can be precisely tuned to optimize these effects. Among these properties, size has been shown to influence key …

Technology-Facilitated Violence And Abuse: Portrayals And Perceptions, Christina S. Walker

University of Kentucky Doctoral Dissertations

In the past, intimate partner violence (IPV) was primarily perpetrated in person. However, due to new mediated communication technologies and capabilities like social media and artificial intelligence (AI), perpetrators can use this technology for various purposes including subjecting others to violence, harassment, and abuse. Such violence can be a form of IPV and is referred to as technology-facilitated violence and abuse (TFVA). TFVA is becoming increasingly prevalent and is encountered by a staggering percent of women. Furthermore, unlike traditional forms of IPV, even men are subjected to TFVA at increasing and disproportionate rates, particularly male teens.

In the current state …

Personality Exceptions: Enhancing Character In Narrative Planners With Internal Memory, Elinor Rubin-Mcgregor

University of Kentucky Doctoral Dissertations

Stories and narratives are powerful tools for forging connections between people, as they induce emotions shared through their audience and help build empathy and understanding through sharing unique perspectives. Interactive stories can do all this and more, as they can be used to better educate and engage their audience. But in such stories, the characters must have consistent personality and human-like emotions in order for the audience to relate to them. Current implementations of personality in interactive narratives either portrays characters with static personality that feel less realistic, or else require a great deal of additional work from the author …

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 …

Non-Invasive Digital Restoration Of Damaged Photographic Film Negatives, Ankan Bhattacharyya

University of Kentucky Doctoral Dissertations

Physical restoration of damaged photographic film causes more damage. Also, existing non-invasive digital restoration of film negatives does not produce print-quality optical images. Instead, they produce X-ray projections, which are not the same as optical projections. This thesis addresses these problems and establishes a framework that can digitally restore old, damaged films without the need to open them physically. Virtual Unwrapping is an existing pipeline that has proven itself over the last couple of decades to work on unopenable papyrus scrolls, like the Herculaneum Scrolls. This thesis utilizes the concept of virtual unwrapping to restore damaged photographic film negatives. Due …

An Ethical Analysis Of International Graduate Student Workers' (Igsws) Employment Vulnerability, Adeola F. Oladeji

University of Kentucky Doctoral Dissertations

International graduate student workers (IGSWs) occupy a distinctive position within U.S. higher education as students, employees, and temporary visa holders. Their academic progress, financial support, and legal authorization to remain in the United States are often closely intertwined, creating dependencies that heighten their vulnerability to exploitation, unequal treatment, and institutional power imbalances. Although previous scholarship has documented these challenges from empirical, legal, and policy perspectives, comparatively little attention has been given to universities' ethical responsibilities toward IGSWs.

This dissertation examines how U.S. higher education institutions should fulfill their ethical responsibilities to international graduate student workers. Grounded in Dewey's pattern of …

Frequency And Phase Synchronization Of Antenna Arrays With Phase Incoherent Microcontrollers, Harley W. Byrd

University of Kentucky Master's Theses

The construction of phased array antennas has traditionally been an expensive and complex task. It has recently been claimed that it is possible to construct high-performance Wi Fi antenna arrays using inexpensive consumer components. Motivated by some limited data available from online presentations of such devices, this thesis covers an attempt to construct a phased-array Wi-Fi antenna using several ESP32 chips, which have native Wi-Fi modulation and demodulation capabilities. While there are many positive aspects associated with utilizing ESP32 chips for this purpose, a key challenge is the inherent phase incoherence of their internal Phase Locked Loops (PLLs). The approach …

Psychology Faculty Publications

Cognitive-behavioral therapy (CBT) patients with minoritized racial/ethnic backgrounds report similar outcomes as White patients but may report weaker alliances and less frequent CBT skill use. Given its transdiagnostic utility, we tested how racial/ethnic background impacted treatment outcomes, the alliance, and therapy skill use in the Unified Protocol (UP). Participants (N = 70, M_age = 33.7, 67% female, 74% White) with emotional disorders completed six sessions of core UP modules. Participants rated their past-week anxiety, depression, and skill use before each session and the strength of the alliance after each session. We tested whether racial/ethnic background moderated the slopes of …

Phonics And Friends: A Critical Multimodal Discourse Analysis Of Popular Teacher Influencers' Content, Zachary T. Milford

University of Kentucky Doctoral Dissertations

This critical multimodal discourse analysis examined how five teacher-influencers aligned with the Science of Reading (SoR) movement performed authority, constructed discourses, and used affective and semiotic resources in viral TikTok videos about reading instruction. Drawing on Kress and van Leeuwen's (2001) multimodal social semiotics, Fairclough's (1992) critical discourse analysis, Foucault's (1977, 1982) theorizations of power, Papacharissi's (2014) theory of affective publics, Ong's (1982) secondary orality, and Taussig's (1993) mimesis and alterity, this interpretive, qualitative, multiple-case study analyzed fifty viral TikTok videos and four semi-structured interviews with teacher-influencers. Data were analyzed through within-case and within-mode coding, cross-modal analysis, and cross-case analysis …

Regulating Galaxy Growth: Ionized Gas Conditions, Star Formation Histories, And Environmental Effects, Shweta Jain

University of Kentucky Doctoral Dissertations

Understanding galaxy formation and evolution requires tracing how baryons cycle between stars, gas, and the interstellar medium (ISM) across cosmic time. The efficiency of star formation, the buildup of metals, and the regulation of gas inflows and outflows are governed by evolving physical conditions within galaxies and their environments. My thesis investigates how the ionized ISM, star formation histories, and environmental processes have shaped galaxy evolution over the past ∼ 12 Gyr. The primary focus of this work is the evolution of the physical conditions of ionized gas in galaxies, including gas-phase metallicity and ionization state. Using new and archival …

Comparing Strength Testing Measures And The Association Of Strength And Body Composition In Young Children, Abigayle R. Spong

Theses and Dissertations--Kinesiology and Health Promotion

Muscle strength is an important component of physical fitness; however, measuring it with isokinetic dynamometry (IKD) is expensive and requires dedicated space. Handheld dynamometry (HHD) provides a practical alternative for field and clinical settings. Thus, the purpose of this study was to compare peak knee flexion and extension torque measured by IKD and HHD in 37 children (ages 5-11 years) and examine relationships with body composition. Participants completed a RAMPing protocol at 90^o knee flexion consisting of two warm-up contractions at 50% and 75% effort followed by three maximal voluntary isometric contractions. Body composition was assessed via DXA scans. …

Perceptions Of Sport Psychology Efforts And Access In Women's Wheelchair Basketball, Lindsay C. Cohen

Theses and Dissertations--Kinesiology and Health Promotion

As the field of sport psychology grows, services and training programs must evolve to properly serve the evolution of athletes seeking care. This could mean discovering new measures, testing different types of interventions, or developing programs that can better accommodate specific populations that are looking for sport psychology services. One such population is para athletes, and although they have expressed interest in learning more about the field of sport psychology and how to implement mental skills efficiently, athletes have reported a lack of access to sport psychology services and sport psychology consultants (SPCs) (Dieffenbach et al., 2009). The purpose of …

Test-Retest Reliability And Validity Of The Gas Exchange Threshold, Erik Ryan Snell Mr.

Theses and Dissertations--Kinesiology and Health Promotion

Theoretically, the gas exchange threshold (GET) demarcates the moderate and heavy intensity domains, whereby exercise performed at and below the GET results in a change in oxygen consumption ([ΔVO₂] ≤ 200 mL), and exercise above the GET results in a slow component (ΔVO₂ > 200 mL). This study examined the reliability and validity of the GET. 14 subjects performed two maximal graded exercise tests (GXTs) to determine the GET and its reliability. The minimal difference (MD = 21W) was applied to determine the GET above (GET_+MD) and below (GET_-MD) power outputs for 30 min …

Biomechanical Effects Of Exercise-Based Interventions In Chronic Nonspecific Low Back Pain: A Systematic Review And Meta-Analysis, Lara De Vecchi Machado

Theses and Dissertations--Kinesiology and Health Promotion

Chronic nonspecific low back pain (CNLBP) is the leading cause of years lived with disability worldwide and represents a complex, multifactorial, and heterogeneous condition. It is characterized by substantial interindividual variability in muscle activation patterns, lumbo-pelvic coordination, and movement strategies. Although exercise is widely recommended as a first-line intervention and its clinical benefits are well established, the biomechanical mechanisms underlying functional improvement remain fragmented in the literature and are rarely synthesized quantitatively.

This dissertation conducted a systematic review with meta-analysis to investigate the biomechanical effects of exercise-based interventions in individuals with CNLBP. A total of 39 studies were included and …

H2 Matrix Compression For Fast Magnetic Field Post-Processing, Calvin M. Demps

University of Kentucky Master's Theses

Large-scale computational electromagnetic simulations frequently require the assembly of dense system matrices, whose computation time and memory cost grow rapidly with problem size and can render high-resolution simulations impractical. This thesis presents a benchmark of the H² hierarchical matrix method applied to the construction of a coupling matrix that maps magnetization current in a structure to the magnetic field at observation points external to the structure. The underlying field interaction is derived from Maxwell's equations and discretized using a Nyström approach, producing a dense matrix.

The method is benchmarked across various geometries of increasing complexity and for increasing mesh …

The Nature And Origin Of The Strodes Creek Member Of The Lexington Limestone, Central Kentucky, Claire J. Mendenhall

University of Kentucky Master's Theses

The Strodes Creek Member of the Lexington Limestone is a small, unusual member that is largely known for its beds of fragmented and overturned stromatoporoids. The Strodes Creek Member occurs as two distinct stratigraphic bodies, wholly encompassed by the Millersburg Member, which represents a shallow, open-marine, mixed-clastic-carbonate platform, characterized by thin-bedded to nodular, fossiliferous calcarenites and calcirudites interbedded with shale. In contrast to the Millersburg, the Strodes Creek exhibits a lithologic background of dark, organic-rich, calcareous shales with a westward-thickening section of very irregularly bedded, stromatoporoid-rich, fossiliferous calcisiltites (packstones and wackestones). The calcisiltites are commonly associated with hummocky crossbedding, pinch-and-swell …
