The Impact Of Hot V. Cold Water Immersion On Post-Exercise Recovery, Cameron Moss, Aaron Krukemeyer

Williams Honors College, Honors Research Projects

Muscle recovery following exercise-induced soreness has been the focus of extensive research and debate, with Cold Water Immersion (CWI) and Hot Water Immersion (HWI) emerging as two of the most widely used modalities. The purpose of this study was to compare the effects of CWI and HWI on muscle recovery by determining changes in maximal force production of knee extension, range of motion (ROM) of the hip joint in flexion, extension, and abduction, and subjective muscle soreness using a validated Likert scale. Seven male recreational athletes participated in hot and cold-water immersion, and passive recovery. Despite thorough data collection, the …

Restoring The Wild East: Predicting Public Support For Cougar And Red Wolf Reintroduction In The Eastern United States, Benjamin Ghasemi, Jeremy T. Bruskotter, John A. Vucetich, L. Mark Elbroch, Robyn S. Wilson, Neil H. Carter, Axel Moehrenschlager, Shelby Perry, Joseph W. Hinton

Michigan Tech Publications

Restoring large carnivores to human-dominated landscapes remains ecologically and socially contentious, though reintroduction may offer important benefits where coexistence is possible. Yet, efforts to reintroduce cougars (Puma concolor) and red wolves (Canis rufus) in the Eastern U.S. face major challenges, largely due to human-caused mortality and opposition. We employed the hazard acceptance model and structural equation modeling to investigate the socio-psychological drivers of public support for reintroduction. Survey data were collected from residents of the Eastern U.S. for cougars (n = 2665) and red wolves (n = 3825). For both species, support was positively associated with perceived personal and societal …

Equity And Justice In Water Pricing And The Effects On Water Distribution System Management, Brian Barkdoll

Michigan Tech Publications

Equity regarding access to potable water is paramount. Municipal Water Distribution Systems supply potable water to users and are essential to public health. To find the optimal price of water to maximize utility revenue and allow changes to the system components for capital and maintenance expenditures, network modeling was performed for 15 real MDWSs. A new power-law price-usage elasticity curve, entitled the Power Law Elasticity Function (PLEF), was used that allowed for various users, both high- and low-income, and a non-discretionary level of usage. It was found that: (1) the maximum profit was obtained when the price was approximately 0.8 …

Multimodal Machine Learning For Alzheimer's Disease Classification Using Adni Biomarker Fusion, Hesameddin Mostaghimi, Hamid R. Okhravi, Bahar Niknejad, Daniel A. Cohen, Michel A. Audette, Alzheimer's Disease Neuroimaging Initiative

Electrical & Computer Engineering Faculty Publications

Despite ongoing advances, accurate diagnosis of Alzheimer’s disease (AD) remains challenging due to its multifactorial nature, comorbidities, and clinical heterogeneity. Accordingly, approaches that combine multimodal data may improve AD classification by integrating complementary information. To investigate this, we evaluated classification performance using a preprocessed ADNI-3 dataset comprising a shared set of clinical/cognitive features along with four imaging modality-based cohorts: trimodal (MRI + amyloid PET + tau PET), MRI + amyloid PET, MRI + tau PET, and MRI-only. We trained a range of supervised machine learning (ML) and deep learning (DL) classifiers using stratified five-fold cross-validation and evaluated performance using accuracy, …

A Performer's Guide To Selected Trumpet Excerpts Of Orchestral Works By Women Composers, Julia Stowell

University of Kentucky Doctoral Dissertations

Orchestral excerpts are brief passages from symphonic repertoire that are intended to demonstrate a player’s musical and technical abilities. The canon of orchestral trumpet audition excerpts has been relatively unchanged for several generations. This established canon of excerpts rarely features works written by women. As orchestras begin diversifying their programs, the frequently requested orchestral excerpts require new considerations to reflect these changes. In order for excerpts to be reflective of the orchestral canon, they must be updated as the canon changes.

Once an excerpt has been identified and obtained, the next issue is addressing its unique musical and technical challenges. …

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 …

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 …

The Power Of A Picture: Building Visual Depictions Of The Eppm Bolstering Sunscreen Application Motivation, Ansley M. George

This study investigates visual depictions of efficacy skin cancer health risk messages. Using Witte's Extended Parallel Processing Model (EPPM) and existing literature on fear appeals and visual persuasion as a theoretical framework, the study aims to explore how self and response efficacy imagery impacts individuals' perceptions of health risk messages in the context of skin cancer prevention when emphasizing specific principles of design. Formative research was employed via qualitative photo sorts and participants were exposed to an assortment of images depicting efficacy in the context of skin cancer prevention where they discussed why they felt they were or were not …

Becoming A Shape, Becoming Yourself: Geometry, Identity, And Belonging In An Early Childhood Classroom, Eva Thanheiser, Molly Robinson, Simon Byeonguk Han, Amanda T. Sugimoto, Courtney Koestler, Mathew D. Felton-Koestler

Mathematics and Statistics Faculty Publications and Presentations

This paper examines how a first-grade geometry lesson became a site for exploring shape, selfhood, and belonging in an early childhood classroom. Drawing on interaction analysis of a lesson built around the picture book The Greedy Triangle , we show how children named personal strengths, identified shapes, followed a triangle through changing categories, reflected on why they liked being themselves, and used their bodies to form polygons. We ask what counts as mathematical activity in this lesson and argue that mathematics is not limited to naming shapes. It also involves noticing attributes, negotiating criteria, tracking transformation, coordinating bodies, and reasoning …

Health Truth To Power: Professional Collaboration To Bolster Trust Against Misinformation, William M. Sage, Keegan D. Warren

Faculty Scholarship

This Article is about health, leaving aside more general challenges to shared civic information today. The Article begins by surveying the principal challenges for health information in post-pandemic, arguably post-truth America, and then describes briefly the sources and limits of medical professional authority. Noting the double-edged sword of free speech guarantees under the U.S. Constitution, the Article continues by commenting on speaking truth to government, to industry, and to the crowd. Next, the Article considers the physicians’ role in speaking truth to power from the perspective of standard medical professional ethics and identity, comparing it to that of lawyers. Finally, …

Does It Matter What People Lie About?, Stefanie Jung, Peter Krebs, Monika Leszczynska

Faculty Scholarship

We investigate whether people’s moral judgments of lies in pre-contractual negotiations differ from their views on whether such lies should give the deceived party a legal right to rescind the contract, and whether these judgments depend on the content of the lie. In a vignette study with 832 German students and 885 participants from Germany, Italy, and the United States, respondents evaluated a range of common negotiation lies. Across samples, participants were generally more likely to deem a lie immoral than to believe it should justify rescission, but the size of this gap varied depending on the lie’s subject. Lies …

Moral Progress In Legal Doctrine, Philip Petrov

Faculty Scholarship

This article integrates the concept of moral progress – here, moral improvement in the thinking and behavior of individuals over time – into the study of legal doctrine. The article first presents a naturalistic account of what moral progress is and describes three of its most historically and analytically important forms: (1) moral circle expansion, (2) moral domain expansion, and (3) increasing sensitivity to proportionality. The article then analyzes three historical developments in U.S. tort law that qualify as instances of moral progress: (1) the partial demise of the “suicide rule” beginning around the 1980s (according to …

The Words Community Dwelling, Spanish-Preferring Mexican/Mexican American Adults Use To Talk About Alzheimer’S Disease And Genetic Testing: Implications For Education And Outreach, Jamie C Fong, Fatima I Chavez, Karla Silos, Mirna L Arroyo-Miranda, Gabriela Castro Castro, Mark E Kunik, Joshua M Shulman, Luis D Medina

Faculty, Staff and Students Publications

Introduction: Hispanic/Latino (H/L) adults are more likely than non-Hispanic White individuals to have Alzheimer's disease (AD), yet fewer than one in five H/L adults has apolipoprotein E (APOE) Ɛ4, underscoring gaps in understanding genetic risk across H/L heritage groups. H/L adults remain underrepresented in AD research that uses genetic data for participant stratification. To inform culturally appropriate educational materials for 16 million U.S. Spanish speakers, we identified culturally salient words Spanish-preferring H/L adults use to describe AD and genetic testing beyond APOE.

Methods: Community-residing, Spanish-preferring Mexican/Mexican American adults (n = 14) completed freelisting interviews, a method eliciting …

Honey-Cnt Memristive Artificial Synaptic Device For Sustainable Neuromorphic Computing System, Md Mehedi Hasan Tanim, Zoe Templin, Harshvardhan Uppaluru, Jinhui Wang, Kuan Yew Cheong, Feng Zhao

Electrical and Computer Engineering Faculty Research & Creative Works

Brain-inspired neuromorphic computing systems require hardware components analogous to biological neurons and synapses. Honey based natural organic memristor has demonstrated promising nonvolatile memristive behaviors, with the advantages of sustainability, environmentally friendliness, and low-cost manufacturing. In this study, carbon nanotubes (CNTs) are added in honey to fabricate honey-CNT memristive artificial synaptic devices. Honey-CNT film is characterized by micro-Raman spectroscopy and the distribution of CNT bundles embedded in the honey-CNT composite layer by cross-sectional scanning electron microscopy for the first time. Critical synaptic functions of the honey-CNT memristor, including spike-rate-dependent plasticity, spike voltage dependent plasticity, learn-forget-relearn, and supralinear spatial summation are revealed, …

Aba Renewal Of Fentanyl Seeking Using A Drug-Prime And Peer Stimulus In Rats, Meagan Blanchard

University of Kentucky Master's Theses

People with opioid use disorder can experience craving and relapse to use when exposed to cues that were previously paired with the drug-taking environment. These cues can be both social and non-social in nature. This study aimed to explore the effect of a peer cue and a drug-prime cue, both together and separately. First, rats were trained to self-administer fentanyl in Context A (peer and drug present). Then, rats extinguished this behavior in Context B (no peer and no drug present) while self-administering saline instead of fentanyl. Lastly, rats underwent 4 different renewal test conditions (control, peer only, drug only, …

The Ability To Resist The Expected Impairing Effects Of Alcohol In Heavy And Light Drinkers, Grace Tomaszewski

University of Kentucky Master's Theses

Alcohol tolerance is defined as a diminished response to the drug owing to repeated alcohol exposures. However, drinkers can compensate for alcohol impairment, particularly when they expect to be impaired in the situation. However, the ability to compensate might depend on the behavior impaired by alcohol and the general tolerance already acquired by the drinker. This study tested the degree to which expecting alcohol impairment would reduce alcohol’s impairing effect on reaction time (RT) and fine motor control in those with heavy and light drinking histories. Light drinkers (n=26) and heavy drinkers (n=28) received a 0.65 g/kg alcohol and performed …

17Β Estradiol Protection Against Medium-Change Neurotoxicity In Organotypic Hippocampal Slice Cultures, Autumn B. Stage

University of Kentucky Master's Theses

Medium change neurotoxicity can disrupt glutamate homeostasis and promote excitotoxic neuronal injury through excessive NMDA receptor activation. 17β estradiol (E2) has demonstrated neuroprotective effects in models of neuronal injury and may regulate glutamatergic signaling through metabotropic glutamate receptors (mGluR2/3). This study investigated whether E2 protects against medium change associated neurotoxicity in organotypic hippocampal slice cultures whether responses differed by sex or hippocampal region. Hippocampal slices from postnatal day 8 male and female Sprague Dawley rats were maintained in culture and exposed to 1, 10, or 100 nM E2 for 24 hours following a five day recovery period. Propidium iodide (PI) …
