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 …

The Strong Black Woman Schema: A Proactive Approach To Conceptualizing And Providing Mental Health Treatment For Black Women Who Identify With The Strong Black Woman Schema, Kendra Mulder

DSW Capstone Projects

The Strong Black Woman Schema is the ideology that Black women should display mental and physical strength, stoicism, and nurturer traits. While Black women who identify with this schema typically associate this term with a positive identity, there are adverse outcomes that stem from this identification. Black women who identify with the Strong Black Woman schema experience higher rates of depression, anxiety, and psychological distress. No treatment modality has been determined to treat Black women who identify with the Strong Black Woman Schema. This capstone presentation will present a systematic literature review that discusses how the Strong Black Woman Schema …

Supporting Social Work Employment-Hosted Practicum Placements: Challenges And Recommendations, Mary Scanlon

DSW Capstone Projects

The Council on Social Work Education (CSWE) named field education as the signature pedagogy of social work education in 2008. The accrediting organization develops policies that accredited social work programs must adhere to within their field education programs. One policy that stood for over forty years required students completing practicums at their places of employment to create learning opportunities beyond the scope of their employment activities. CSWE altered that policy in its 2022 Educational Policy and Accreditation Standards (EPAS) and now allows programs to let students count their paid work time as field hours. This is a significant shift in …

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 …

Physical Inactivity And Single-Female Caregivers, Johanna Hoch, Rachel Hogg-Graham Dr., John Lyons Dr., Maureen Jones Dr.

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

Physical activity is vital for human health. However, many adults in the United States and beyond do not reach the pre-determined recommended levels of activity needed for health benefits. Single-female caregivers present a unique and vulnerable population that is often more inactive than their partnered peers or single-male caregivers. The primary purpose of this cross-sectional investigation was to identify the prevalence of physical inactivity in single-family, female-led households and determine differences in personal factors and social determinants of health between single-female caregivers who indicated they were physically active compared to single-female caregivers who indicated they were not physically active. A …

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 …

Multiscale And Multimodality Optical Imaging Of Brain Hemodynamics And Function, Mehrana Mohtasebi

Theses and Dissertations--Biomedical Engineering

Frequent measurement of cerebral hemodynamics is crucial for continuous assessment of brain function and health. Low-frequency oscillations (LFOs; < 0.1 Hz) have shown promise as an indicator of altered neurologic activity in the abnormal brain. Moreover, quantification of temporal correlations in LFOs across distinct brain regions enables mapping of regional neurovascular disorders. Portable diffuse optical techniques such as near-infrared spectroscopy (NIRS) and diffuse correlation spectroscopy (DCS) enable noninvasive and continuous measurements of cerebral oxygenation and cerebral blood flow (CBF), respectively. However, most NIRS/DCS systems use limited numbers of discrete light sources and detectors and thus lack combinations of high temporal/spatial resolution and large field-of-view (FOV) for brain imaging. Recent development of an innovative noncontact speckle contrast diffuse correlation tomography (scDCT) in our lab provides a low-cost and portable tool for high-density imaging of CBF distributions over large FOVs. The scDCT uses a galvo-mirror to remotely deliver coherent point near-infrared light to multiple source positions and a CMOS camera as a high-density 2-D detector array to quantify spatial fluctuations of diffuse laser speckles, resulting from movement of red blood cells. Boundary CBF data were input to a unique finite-element-method (FEM)-based reconstruction algorithm for 3-D imaging of CBF distributions. However, scDCT was hindered for extracting LFOs due to its low sampling rate. In this study, scDCT was optimized to achieve high sampling rates and fast image reconstructions by use of moving window algorithms with parallel computations (Project 1). Power spectral density (PSD) analysis was performed to investigate altered LFOs during transient cerebral ischemia in neonatal piglets. Transient cerebral ischemia caused reductions in both CBF and PSD, supporting inclusion of scDCT in the growing field of LFO analysis. One remaining limitation was the long computational time required for 3-D reconstruction, which prohibited real-time applications. To overcome this limitation, a depth-sensitive diffuse speckle contrast topography (DSCT) method was developed for analyzing scDCT data to achieve fast and high-density 2-D mapping of CBF distribution without the need of complex and time-consuming 3-D reconstructions (Project 2). New head-simulating phantoms with known optical/geometric properties were designed and fabricated to evaluate the spatial resolution and depth sensitivity of DSCT method. In-vivo experiments verified the capability of DSCT in tracking dynamic changes in CBF at different depths during CO₂ inhalation and transient cerebral ischemia in rats. In addition to preclinical studies, a low-cost, wearable, fluorescence eye loupe (FLoupe) device was invented for intraoperative visualization of brain tumor margin in the clinic (Project 3). Consistent results were observed against an expensive, large, standard fluorescence operative microscope for the guidance of tumor resection. Overall, through 3 projects this dissertation demonstrated a variety of noninvasive noncontact optical technologies (scDCT, DSCT, and FLoupe) that enabled multiscale (rodents, piglets, and humans) and …

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 …

Digital Twins For Ancillary Transportation Asset Data Management, Ashtarout Ammar

Theses and Dissertations--Civil Engineering

Transportation Asset Management (TAM) is a data-driven decision-making process to maintain and extend the serviceability of transportation assets throughout their lifecycle. TAM is an extensive data process requiring accurate, high-quality information for better decision-making. A significant challenge that state Departments of Transportation (DOTs) face is allocating limited funds to optimize their assets’ performance. The criticality of this challenge increases when state DOTs need to manage a wide variety of assets distributed along with a vast network; thus, they prioritize the management of high-value assets and visible ones such as bridges, and they pay less attention to ancillary assets even though …

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 …

The Reflexitve Fritz Lang: Meta-Cinematic And Genre Critiques In His American Films, Justin J. Roberts

Theses and Dissertations--English

Director Fritz Lang is best remembered and most celebrated for the films he made in Germany, including Metropolis (1927) and M (1931), between 1919 and 1933. But he spent over half of his career working in Hollywood. This dissertation is a reconsideration of his American films, focused on how Lang used various Hollywood genres to question and critique the way Hollywood films and genres functioned, as well as trends within those genres. This dissertation is a roughly chronological reading of twelve of Lang’s American films, sorted by genre. We can see how his thinking about the function of film and …

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 …

Myth, Mockery, & Misery: An Evolution Of Disillusion In Modern-War Expression, Richard W. Halkyard

Theses and Dissertations--English

Industrialization in 19th-Century America yielded a regrettable by-product: the modernization of warfare. Mass armies, technological innovation, and unprecedented rates of industrial productivity prompted the creation of machines designed to inspire fear, increase destructive capability, and inflict mass-death. The modernization of warfare altered forever the way war was experienced and represented literarily. Authors who attempted to represent the Civil and Spanish-American Wars, as well as World War I, articulated modernized warfare with a disillusionment which stems from the tragically dehumanizing effects of mechanical violence on an industrial scale. Myth, Mockery, & Misery argues that as far back as 1862, romantic idealization …

Exploring The Molecular Basis Of Touch: A Comparative Analysis Of Gene Expression In Sensory Corpuscle-Rich And Corpuscle-Poor Skin Regions In The Duck, Thomas Hart

Theses and Dissertations--Biology

Cutaneous touch is facilitated by discrete cellular complexes composed of non-neuronal cells associated with mechanoreceptor neuron endings. The non-neuronal cells of these cutaneous end organ complexes (CEOCs) are believed to contribute to touch, but their role in touch sensation remains unclear. To better understand the function of CEOC cells, we sought to characterize the transcriptional profile of CEOC-rich tissue and identify genes expressed in CEOC cells. Bill skin of the tactile foraging Pekin duck (Anas platyrhynchos) is dense with CEOCs, specifically the avian analogs of mammalian Pacinian and Meissner corpuscles, while corpuscles in duck foot skin are scarce. Using RNA …

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 …

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 …

Property Protocols And The Spatial Relations Of Real Estate Technologies, Ian Spangler

Theses and Dissertations--Geography

The dissertation contributes to our understanding of the technologically mediated, professionally managed social relations of private property, and specifically, their consequences for housing and home. I analyze standards and protocols for real estate data transfer, such as the multiple listing service, arguing that these standards play an increasingly important role in how real estate capital authenticates property relations. Focusing on technologies that leverage these standards in order to manage, exchange, and marketize housing, I show how standards often derive from moral values grounded in rubrics of white upper-class masculinity and national border-making. In making this argument, I draw on interviews, …

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 …

Perceptual Dialectology Of Tulsan Speakers Of English, Andrew Carter

Theses and Dissertations--Linguistics

The present study analyzes new interviews from fifteen Tulsan speakers of English and maps produced by draw-a-map tasks. The interviews and subsequent map tasks were conducted over the course of the winter of 2021 for the purpose of this thesis and have been analyzed for folk linguistic information about the perceptions of Tulsa and the rest of the state. The study finds that Tulsan speakers hold similar dialectal perceptions about both their own city and other locations as their fellow Oklahomans, and also provides evidence of a deteriorating faith among Tulsans in the existence of the northern-southern dialectal divide compared …

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 …

“Local, But Intelligent”: Language Ideologies In The Informant Biographies Of The Linguistic Atlas Project, Nicholas A. Passarelli

Theses and Dissertations--Linguistics

This thesis argues for the relevance of the Linguistic Atlas Project (LAP) for studies of language ideologies, indexicality, and enregisterment. The LAP represents the largest dialect survey of North American English to date, offering an abundance of historical linguistic data for research in dialectology, linguistic geography, and variation over space and time. Additionally, the LAP also contains additional sources of sociolinguistic data, including informant biographies — documents written by fieldworkers at the conclusion of the LAP interview that summarize an informant’s demographic profile, as well as their personality, speech, and caliber as an interviewee. Rife with subjective judgments from the …

Forum On “Conquest”: Past-Present Politics Of Coloniality In Cinema On Latin America, Stephen Jakob Turner

Theses and Dissertations--Hispanic Studies

My dissertation analyzes the representation of Spanish “Conquest” in film as a critical commentary on the cultural present. Chapter 1, “Directorial Discord: The Cultural Politics of Representation in Apocalypto (USA/Mexico/UK, 2006) and Retorno a Aztlán (Return to Aztlán, Mexico, 1991)” focuses on the representation of the (im)possibility of Indigenous heroic protagonism and futurity in the origins of “Conquest.” Chapter 2, “‘The World is Thus’: Resistance and the Power of Ambivalent Conversion in Gabriel Retes’s Nuevo Mundo (The New World; Mexico, 1976) and Roland Joffé’s The Mission (USA/Paraguay, 1986)” posits that the “Conquest” problematizes the myth of …

Truth In Horror: Cinematic Representations Of Social Violence In Spain, Latin America, And The United States, Kelly Ferguson

Theses and Dissertations--Hispanic Studies

My dissertation, Truth in Horror: Cinematic Representation of Social Violence in Spain, Latin American, and the Latinx United States, investigates the recent explosion of political horror films that straddle the past and present, reflecting both the current political moment and the polemic historical memories of state repression against racialized others and ideological dissidents. Chapter One, “Paranoid Horror and the Return of Franco,” studies four Spanish horror films, Tras el cristal (1986), Pa negre (2010), Mientras duermes (2011), and Musarañas (2014), all of which feature child protagonists that seek out truth about violent family secrets, but ultimately reject it as …
