Theses and Dissertations--Early Childhood, Special Education, and Counselor Education

The purpose of this study was to evaluate the effects of two peers versus one peer on the rate of aided language modeling. The peers were trained and then implemented the communication strategy while playing a tabletop game with an AAC user with extensive support and complex communication needs (ESCCN). A multitreatment design was used to compare the effects of the rate of aided language models (ALM) provided by peers, the rate of communicative acts (CA) provided by the AAC user, and the fidelity of peer implementation of ALM when two peers versus one peer played a tabletop game with …

The Effects Of Exogenous Enzyme Supplementation On The Performance, Bone Quality, And Nutrient Utilization Of Broiler Chickens, Megan Bauer

Theses and Dissertations--Animal and Food Sciences

Two experiments were conducted to examine the effects of Allzyme® Spectrum supplementation to a reduced nutrient diet on the growth performance, energy and nutrient digestibility and utilization, bone quality, and jejunal digesta viscosity in broiler chickens. Each experiment used 300 one-day old Cobb by-product breeder chicks with 5 treatments, 10 replicates, and 6 birds per replicate cage in a randomized complete block design. The only differences between the two experiments were experiment 1 lasted for 21 days using a corn-soybean meal-based diet and experiment 2 lasted for 22 days using a wheat-soybean meal-based diet. The 5 treatments included a positive …

Trademarks, Nfts, And The Law Of The Metaverse, Michael D. Murray

Law Faculty Scholarly Articles

This Article discusses the early encounters of NFTs, trademarks, and the legal system. This work will examine the areas where NFT creators are getting into or are likely to get into trouble with the law and policy of trademark infringement, trademark dilution, and the related legal causes of action of false endorsement and false designation of origin. United States law is being applied in lawsuits that already are being adjudicated in the real world concerning subject matter that exists only in cyberspace, the pre-cursor to the metaverse.

Generative Ai Art: Copyright Infringement And Fair Use, Michael D. Murray

Law Faculty Scholarly Articles

The discussion of AI copyright infringement or fair use often skips over all the required steps of the infringement analysis in order to focus on the most intriguing question, “Could a visual generative AI generate a work that potentially infringes a preexisting copyrighted work?” and then the discussion skips further ahead to, “Would the AI have a fair use defense, most likely under the transformative test?” These are relevant questions, but without considering the actual steps of the copyright infringement analysis, the discussion is misleading or even irrelevant. This neglecting of topics and stages of the infringement analysis fails to …

Reading Legal Ethnographies To Re-Map Legal Pluralism: A Pospisilian Corrective To The Prevailing Dichotomous Description Of Afghanistan’S Legal Order, Tomas Ledvinka, James M. Donovan

Law Faculty Scholarly Articles

This article explores several ethnographies (both academic and para-academic) of Afghanistan’s traditional justice (jirgas and shuras) in order to illuminate contrasts of their conceptual approaches at different periods of the country’s history. In this genealogy we identify ethnographic observations of the levels at which various sociolegal authorities operate and which often elude standard international ontology. The article takes the legal ethnographies as signposts for a conceptual reframing of the legal situation in the country by drawing upon Pospisil’s legal-anthropological conceptual approach which offers an alternative to generic global legal models based on binary oppositions such as formal–informal, state–non-state or official–traditional. …

Yellow fever virus (YFV) is a reemerging global health threat, driven by several factors, including increased spread of the mosquito vector and rapid urbanization. Although a prophylactic vaccine exists, vaccine hesitancy, supply deficits, and distribution difficulties leave specific populations at risk of severe YFV disease, as evidenced by recent outbreaks in South America. To establish a treatment for patients with severe YFV infection, we tested 37 YFV-specific monoclonal antibodies isolated from vaccinated humans and identified two capable of potently neutralizing multiple pathogenic primary YFV isolates. Using both hamster and nonhuman primate models of lethal YFV infection, we demonstrate that a …

A Multilevel Nonlinear Approach Of Piecewise Regression For Detecting Turning Points: Developing An Alternative Platform With An Application Of Timss, Jing Zhang

Theses and Dissertations--Education Sciences

Studies in recent years have explored the methods of identifying the turning points when dealing with the non-linear relationship. Four approaches applied by researchers, the eyeball approach, the establishment approach, the theory-driven approach, and the data-driven approach, are all under the traditional piecewise regression framework when seeking turning points. Thus, the purpose of this study is to introduce a multilevel piecewise regression model to identify the turning point beyond the traditional piecewise regression, as a completely non-linear approach.

Data used for this study is TIMSS 2019 United States sample. TIMSS is a project guided by the International Association for the …

Removing The Masc: Dismantling Gendered Occupations Through Social Work Education, Austin M. Raines

DSW Capstone Projects

The “Masculine mystique” refers to a psychological mask that men wear, enabling them to maintain power and distance themselves from traits associated with femininity” (Kahn, 2009, p. 283). This capstone project seeks to solve the Social Work Grand Challenge of improving the lives that hegemonic masculinity harms and limits. It emphasizes the relationship between the two areas of life (work-home), once thought to exist in different realms but are today more interwoven than ever (Lin & Burgard, 2018; Sok et al., 2014). Men have higher rates of traumatic injuries and exposure to significant physical risks, violence hazards, and stricter normative …

Saint Louis, Missouri Maternal Mortality Prevention Program: Rose Program, Abbi Peck

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

In the United States, maternal mortality has become a growing public health concern after recent studies revealed significant disparities in maternal health outcomes when compared to other high-income countries (The Commonwealth Fund, 2020). The World Health Organization (WHO) defines maternal mortality as the death of a pregnant woman or the death of a woman within 42 days of delivery, miscarriage, termination, or ectopic pregnancy (Centers for Disease Control and Prevention, 2022a). From 2017-2019, the maternal mortality in Saint Louis, Missouri, the state’s largest and most populated metropolitan area, was determined to be 36.4 maternal deaths per 100,000 live births. This …

Implementation Of A School-Based Adolescent Pregnancy Prevention Program In Harlan County, Kentucky, Jaycea Frederick

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

Kentucky has the 6^th highest rate of adolescent pregnancy in the United States and Harlan County ranks among the highest rates in the state. Adolescent pregnancy is a public health problem and costs taxpayers in the United States around $9.4 billion each year. Overall, there have been declines in adolescent pregnancy but the national average soars above those in other Western industrialized nations such as the United Kingdom. Implementing a comprehensive sexual health education program in a public school setting is an efficient strategy to reach numerous adolescents and influence sexual health knowledge and help to delay the initiation …

3-Dimensional Muscle Constructs: Using Hydrogels In Order To Model The Effects Of Exercise In Disease Conditions, Mark Mchargue

Theses and Dissertations--Biomedical Engineering

Currently, there is no standard in vitro model for studying the effects of mechanical stimulation on muscle in type II diabetes. Existing models primarily utilize electrical stimulation, which does not fully recapitulate the effects of exercise. In this thesis, we create a standardized in vitro model of murine muscle that can recapitulate the benefits seen in exercise when mechanically stimulated. Moreover, we show that a type II diabetes environment has similar effects on the muscle in vitro as well as in vivo.

A Wearable Fiber-Free Optical Sensor For Continuous Measurements Of Cerebral Blood Flow And Oxygenation, Xuhui Liu

Theses and Dissertations--Biomedical Engineering

Wearable technologies for continuous monitoring of cerebral hemodynamics in freely behaving subjects not only advance our understanding of cognitive processing and adaptive behavior, but also provide vital information for diagnosis and therapeutic assessment of cerebral diseases associated with hypoxia/ischemia. Wearable near-infrared diffuse optical techniques have been used at the bedside to probe deep cerebral hemodynamics, including near-infrared spectroscopy (NIRS) for cerebral oxygenation measurement and diffuse correlation spectroscopy (DCS) for cerebral blood flow (CBF) measurement, respectively. However, most systems are relatively large and expensive, and use rigid fiber-optic probes that significantly constrain subject’s movement. A novel, wearable, fiber-free diffuse speckle contrast …

Quantitative Microbial Risk Assessment (Qmra) For Urban Stormwater Reuse After Treatment Through A Bioretention System, Isaac Oluk

Theses and Dissertations--Civil Engineering

Bioretention, also referred to as a stormwater biofilter, is an extensively used low-impact development technology for both stormwater management and water quality gains. However, little attention has been paid to the acceptability and uncertainty of human health risks associated with the treatment performance of bioretention filter media, and non-potable water reuse scenarios to guide decision-making and system design. This study uses bioretention mechanistic modeling paired with quantitative microbial risk assessment (QMRA) under uncertainty to evaluate human health risks from two reference pathogens – Campylobacter jejuni and Cryptosporidium. Consumption of irrigated green salad, consumption of raw green salad washed with effluent, …

Do Transportation Network Companies Affect Road Safety Outcomes: A Spatially Detailed Analysis In San Francisco, Vedant Shriniwas Goyal

Theses and Dissertations--Civil Engineering

US traffic fatal deaths have steadily risen since 2010, with the past few years witnessing an unusual trend increase. To reverse such a dangerous trend, one must understand how and why road crashes occur and which factors are causing them. Emerging transportation technologies have shown the potential to improve mobility and safety. However, such technologies are not inherently beneficial and could worsen road safety if not effectively implemented. One such transportation technology that warrants investigation is the rise of ridesharing services, also called Transportation Network Companies (TNCs). The primary goal of the dissertation is to explore the statistical relationship between …

Practical Ai Value Alignment Using Stories, Md Sultan Al Nahian

Theses and Dissertations--Computer Science

As more machine learning agents interact with humans, it is increasingly a prospect that an agent trained to perform a task optimally - using only a measure of task performance as feedback--can violate societal norms for acceptable behavior or cause harm. Consequently, it becomes necessary to prioritize task performance and ensure that AI actions do not have detrimental effects. Value alignment is a property of intelligent agents, wherein they solely pursue goals and activities that are non-harmful and beneficial to humans. Current approaches to value alignment largely depend on imitation learning or learning from demonstration methods. However, the dynamic nature …

Together Now, Alfonso Zapata

Theses and Dissertations--English

Together Now is a collection of poems by Alfonso Zapata, with work written between 2021 and 2023 at the University of Kentucky. This thesis contains poems which examine the close relationship between families, art, and the histories each contain. These poems use these subjects in order to illustrate the emotional and physical impact communities have upon those who live in them; art can evolve a person, shape them in beautiful ways, and give us the ability to process tragedy together; on the other end of the spectrum, societal neglect, environmental crisis, and food insecurity can rip these communities apart potentially …

Echoed Malice: Identity And The Doubled Voice In Gothic Horror, Brandon West

Theses and Dissertations--English

My dissertation argues we would benefit from focusing on the voice when analyzing gothic and horror texts. That is, I contend, there remains significant fertile ground for us to till in these texts if we shift our focus to the voice and its various iterations across these texts’ long history. To demonstrate this point, I delineate three variations of this theme: the doubled voice in the possession narrative, the split voice in the ventriloquist-dummy dynamic, and the inherent uncertainty of the voice without discernable origin. Each of these variations, I argue, offers fruitful readings of oft-studied texts and, moreover, offers …

Ovid's Caeneus As A Queer Hero: Understanding Gender And Gender Variance In The Ancient Mediterranean., Rj Palmer

Theses and Dissertations--Modern and Classical Languages, Literature and Cultures

Caeneus, as written in Ovid’s Metamorphoses, is a notable blend of ancient and Hellenistic versions of the myth. Ovid’s Caeneus can be understood as a transgender man, since he was assigned female at birth, but asks for his gender to be changed by the god Neptune, and goes on to live the rest of his life with the body, appearance, and social roles of a man. Ovid incorporates Caeneus’ trans identity with his use of grammatical gender endings for Caeneus, using masculine gender for Caeneus except when discussing his pre-transition childhood, or when the centaurs address him mockingly while fighting. …

Field Tests Of A Uav-Compatible Spectrometer To Evaluate Its Suitability For Detailed Soil Radon Potential Mapping, Alexandria Briahnne Thomas

Theses and Dissertations--Earth and Environmental Sciences

As part of ongoing research on radionuclide mapping and radon hazard characterization, field tests were performed to evaluate the suitability and limitations of a UAV-compatible gamma spectrometer. To date, this data set includes completed stationary data collection, mobile ground collection, multi-level UAV flights over a known material transition, as well as redundant ground and multi-level UAV data collection over a relatively uniform area. Total counts were used as a measure of soil radionuclide levels for our data collected above background. Although our test sites were in regions underlain by bedrock with high indoor radon levels, uranium counts were barely above …

Variation In Behavioral Strategies For Coping With Environmental Uncertainty, Allison Mclaughlin

Theses and Dissertations--Biology

My dissertation investigates how animals behaviorally respond to environmental change, especially when there is limited information about that change. Uncertainty about the environment comes in various forms, including food resources which vary unpredictably and novel cues which present an unknown level of potential risk or benefit. Various behavioral strategies help animals cope with such uncertainty. Tactics to manage unpredictable variation in food include gathering information to reduce uncertainty (sampling) and strategically adjusting preference or aversion to variation in resources (variance-sensitivity). To manage the uncertainty of a novel cue, animals may generalize their previous experience with similar cues, or they may …

The Appalachian System Of Basins And Platforms As A Tectonostratigraphic Analogue To The Barents Sea Shelf: Where Arctic Meets The Appalachians, Gustavo De Aguiar Martins

Theses and Dissertations--Earth and Environmental Sciences

Divided between Norway and Russia, the Barents Sea shelf (BSS) is an ~1.4 million km² Arctic province, containing significant hydrocarbon accumulations. However, much of the area is frontier, and geologic data are often restricted or unavailable. One strategy to mitigate lack of geologic data is the use of analogues from well-known, mature basins. Even though there have been attempts to use analogues to study the geology of the BSS, such use is limited. Moreover, no analogue, to my knowledge, has been capable of addressing the regional tectonostratigraphic development of the shelf as a whole.

In this research, the Appalachian …

Discovery Of The Middle Mantle Transition Zone (Mmtz) And Its Geodynamic Significance, Yuping Wang

Theses and Dissertations--Earth and Environmental Sciences

Global mantle discontinuities and mantle transition zones are crucial to the earth’s evolution. By employing K-Means clustering, which belongs to cluster analysis in machine learning (ML), on shear velocity variation data, we generate heterogeneity percentage profiles for three different global tomographic models (Models S362WMANI+M, SEMUCB-WM1, and S40RTS). Key cluster percentage shifts, which are observed at around 400 km, 650 km, 1050 km, 1500 km, and 2700 km, suggest global mantle discontinuities at corresponding depths. All profiles also indicate a global discontinuity in the lower mantle between 2200 km and 2600 km. The middle mantle transition zone (MMTZ), bounded between 1050 …

Applications Of Digital Terrain Modeling To Address Problems In Geomorphology And Engineering Geology, Sarah Johnson

Theses and Dissertations--Earth and Environmental Sciences

This dissertation uses digital terrain modeling and computational methods to yield insight into three topics: 1) evaluating the influence of glacial topography on fluvial sediment transport in the Teton Range, WY, 2) integrating regional airborne lidar, UAV lidar, and structure from motion photogrammetry to characterize decadal-scale movement of slow-moving landslides in northern Kentucky, and 3) applying machine learning methods to surficial geologic mapping.

The role of topography as a boundary condition that controls the efficiency of fluvial erosion in the Teton Range, Wyoming, was investigated by using existing lidar data to delineate surficial geologic units, geometrically reconstruct the depth to …

The Psycho-(Geo)Political Driving Forces Of Comfort Women Social Movements In South Korea, Jaeyeon Lee

Theses and Dissertations--Geography

"Comfort women" refers to the estimated 80,000 to 200,000 women who were forced to serve the Japanese imperial army sexually, physically, and mentally during WWII in and beyond the Asia-Pacific region. Since 1992, Korean activists have held the Wednesday Demonstration, which is the weekly protest in front of the Japanese Embassy in Seoul, to call for an official apology and legal compensation from the Japanese government. Since 2011, Korean activists have also installed comfort woman statues in and outside of South Korea.

This dissertation examines the psycho-political driving force behind the Wednesday Demonstration and comfort woman statue movements in South …

‘A Category Of Their Own’: Quantitative Methods In The Use Of Pile-Sort Data In Perceptual Dialectology, Zachary Ty Gill

Theses and Dissertations--Linguistics

The purpose of this study is to investigate how Mississippi Gulf Coast Creoles perceive language differences in their home area. A pile-sort task was carried out in which respondents were given stacks of cards with local communities written on them and instructed to stack together the regions where people “talk the same.” Once the piles were made, the fieldworker discussed their sortings with the respondents. The stacks were analyzed by means of a hierarchal agglomerative cluster analysis and non-parametric multidimensional scaling with k-means cluster analysis overlays to extract the perceived dialect areas. The groupings reveal that respondent strategies are based …

Language Ideologies In Deep South Korea: Voices Of Jeollanamdo English Teachers, Ian Schneider

Theses and Dissertations--Linguistics

Language ideologies serve as shared beliefs and key frames that link language and society, mediating both macro-level social forces and micro-level interactions. Through this lens, this thesis compares the ideological perspectives and experiences of expatriate and local English teachers working in secondary-level schools in the rural province of Jeollanamdo, South Korea. Through thematic analysis of semi-structured interviews, this study argues for complexity and nuance in how language teachers from distinct backgrounds perceive and negotiate dominant English language ideologies in Korean society. Moreover, these ideological perspectives differ between teachers of local and expatriate backgrounds, or teachers working in urban and rural …

Rhyming Tactics In Korean Hip-Hop With Two Approaches Of English And Korean Syllable Structures, Gihyun Gal

Theses and Dissertations--Linguistics

Rhyming Tactics in Korean Hip-Hop with Two Approaches of English and Korean Syllable Structures

Today, Korean Hip-Hop (KHH) has been slowly moving beyond a localized pop culture through the internet and media. This study finds that rhyming patterns in KHH are much more complex than prior research suggests. Especially, this study focuses on an evolution of Korean Hip-Hop through the time such as since 1989 to 2015. Park (2016) discusses how Korean rappers think about using rhyming tactics as "[m]over, the concept of rhyming was not conceptualized as belonging to the Korean language by most of rappers. Even if rappers …

It's Football Time In The Bluegrass!: The Community Of Uk Football Athletes & Fans And Their Shared Language & Religious Practices, Virginia Anderson

Theses and Dissertations--Linguistics

This thesis observes how University of Kentucky fans and athletes create both a community and a religious experience surrounding the sport of football through their use of language. Fans and athletes took part in interviews that implicitly asked about religious experiences and community. Once the interviews were completed, they were transcribed and underwent open thematic coding. Themes were gathered from the interviews and compared to determine if the fans and athletes were separate subcommunities or if they were simply part of the at-large University of Kentucky football program community. These themes also aided in determining if and how fans and …
