Echoed Malice: Identity And The Doubled Voice In Gothic Horror, Brandon West Jan 2023

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 …


Representations Of Military Women In Contemporary War Stories, Deborah Daley Jan 2023

Representations Of Military Women In Contemporary War Stories, Deborah Daley

Theses and Dissertations--English

Representations of Military Women in Contemporary War Stories seeks to understand how war stories influence our perception of who belongs in military service. With the canon of western war writing dominated by the memoirs and stories of white men, what happens when service women enter into and author war stories, and how does their appearance destabilize questions of who is fit for military service? War literature provides an important lens through which to observe how military service is scripted by culturally and socially constructed expectations of one’s gender, race, and occupation. In male-dominated workplaces, women must not only perform in …


Ovid's Caeneus As A Queer Hero: Understanding Gender And Gender Variance In The Ancient Mediterranean., Rj Palmer Jan 2023

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. …


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 Jan 2023

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 …


Variation In Behavioral Strategies For Coping With Environmental Uncertainty, Allison Mclaughlin Jan 2023

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 Jan 2023

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 …


Perceptual Dialectology Of Tulsan Speakers Of English, Andrew Carter Jan 2023

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 …

Masculinidades Insubordinadas Y Subversivas. La Construcción De La Figura Del Gaucho Rebelde En La Literatura Rioplatense A Través De La Representación De Tres De Sus Tipos Humanos Más Característicos: El Cantor, El Matrero Y El Caudillo, Miguel Angel Martos Maldonado

Theses and Dissertations--Hispanic Studies

This research work explores the construction of the masculinity of the rebellious gaucho in several literary works written by authors from the River Plate, and how it serves as a vehicle for the transmission of ideas –often of political content– of their creators. The basic concept underlying this study is that some writers of works set in the rural world show a serious social commitment, and often combine their literary activity with politics. For this reason, they choose as a key figure in their writings a gaucho who rebels against authority and, emphasizing in him the traits traditionally considered as …


Taken: Slavery, Forced Migration, And Environment In The Early United States, Christopher L. Leadingham Jan 2023

Taken: Slavery, Forced Migration, And Environment In The Early United States, Christopher L. Leadingham

Theses and Dissertations--History

This work examines the development and collapse of the slave trade in Kentucky. It pushes readers to think about the slave trade in an environmental context. The development of the slave trade in the state depended on the violent acquisition of Indigenous lands. The networks of credit and capital that settler colonists established—wealth concentrated in land, stock, crops, and people—fueled the development of a slave system west of the southern mountains. That system increasingly relied on the forced movement of enslaved people in and through Kentucky. The state’s legal system and other institutions worked to support slave trading companies especially …

Investigation Of Key Mechanisms Of Contact Dependent Growth Inhibition Systems In Burkholderia Cepacia Complex Species, Zaria K. Elery

Theses and Dissertations--Microbiology, Immunology, and Molecular Genetics

Burkholderia cepacia complex is a group of closely related environmental bacteria that can exacerbate disease in immunocompromised individuals. B. cepacia bacteria are equipped with an arsenal of mechanisms to cooperate and compete for nutrients in various polymicrobial environments. Contact-dependent growth inhibition (CDI) systems are antagonistic mechanisms widespread among proteobacteria. CDI systems consist of Two Partner Secretion pathway proteins that function to deliver the toxic C-terminal portion of the large effector exoprotein (termed ‘BcpA’ in Burkholderia-type CDI systems) to the cytoplasm of a compatible recipient bacterial cell upon direct cell to cell contact. The translocation of BcpA out of the …


Investigating The Relationship Between Metabolic Reprogramming And Peripheral Cd4+ T-Cell Inflammation In Human Type 2 Diabetes Pathogenesis, Gabriella Kalantar Jan 2023

Investigating The Relationship Between Metabolic Reprogramming And Peripheral Cd4+ T-Cell Inflammation In Human Type 2 Diabetes Pathogenesis, Gabriella Kalantar

Theses and Dissertations--Microbiology, Immunology, and Molecular Genetics

Chronic, low-grade systemic inflammation rises in obesity and promotes type 2 diabetes (T2D). Circulating immune cells are key indicators of obesity and T2D pathogenesis. T cells outnumber monocytes, in blood, suggesting that T cells might fuel peripheral inflammation in obesity/T2D. Our lab’s work supports this idea by identification of a Th17 cytokine profile in T2D from T-cell stimulated peripheral blood mononuclear cells. Work described herein further supported this work by demonstrating that T cells dominate peripheral inflammation over monocytes across the spectrum of obesity and glycemic control. Our lab has also recently shown that inflammation changes during prediabetes (preT2D), identified …


Substrate Selection And Effector Gating In The Helicobacter Pylori Cag Type Iv Secretion System, Mackenzie E. Ryan Jan 2023

Substrate Selection And Effector Gating In The Helicobacter Pylori Cag Type Iv Secretion System, Mackenzie E. Ryan

Theses and Dissertations--Microbiology, Immunology, and Molecular Genetics

Helicobacter pylori is a recognized carcinogen and gastric colonization by strains that harbor the cag type IV secretion system (1) is the strongest known risk factor for stomach malignancy. Gastric adenocarcinoma is the fourth leading cause of cancer-related deaths world-wide ( > 700,000 deaths annually), with H. pylori directly contributing to the development of more than one million new cases of cancer per year accounting for 5.5% of all malignancies. H. pylori exploits cag T4SS activity to alter the mucosal microenvironment by delivering diverse immunostimulatory cargo into target gastric epithelial cells. Currently, the mechanisms by which the cag T4SS …

Foster Caregiving: How Interactions With The Child Welfare Agency Impact Foster Parent Satisfaction, Recruitment, And Retention, Ethan Engelhardt

Theses and Dissertations--Social Work

Professionals of the child welfare system in Kentucky have continuously worked to retain and recruit new foster parents for the foster care system. Foster parents are uniquely placed in a surrogate caring position for children removed from their homes for reasons of abuse or neglect. Foster parents accept this role and step in to provide a safe and loving household for many children. There are more than 9,000 children placed in Out of Home Care (OOHC) on any given day in Kentucky, leaving many children in need of a loving and supportive household. Foster parents hang in the balance between …


Probabilistic Methods For Inferring The Order Of Pathway Alterations During Carcinogenesis And Cancer Subtype Classification, Menghan Wang Jan 2023

Probabilistic Methods For Inferring The Order Of Pathway Alterations During Carcinogenesis And Cancer Subtype Classification, Menghan Wang

Theses and Dissertations--Statistics

Carcinogenesis is a complex process involving somatic mutations in a number of key biological pathways. Studying cancer evolution is an important task which contributes to better understanding of cancer biology and facilitates identification of new therapeutic targets. We focus on two important questions in cancer evolution. The first question is to delineating the temporal order of pathway mutations during tumorigenesis. And the other question is to cluster patients into biologically meaningful cancer subtypes. We present new statistical methods to 1)leverage functional annotations of mutations to enhance estimation of the order of pathway mutations during carcinogenesis, 2) incorporate intra-tumoral heterogeneity information …


Tolerance Intervals For Various Regression Models, Xitong Zhou Jan 2023

Tolerance Intervals For Various Regression Models, Xitong Zhou

Theses and Dissertations--Statistics

Among statistical intervals, confidence intervals and prediction intervals are well-known and commonly used. In many applications, the problem becomes finding an interval that covers at least a certain proportion $P$ of the population for a characteristic of interest with a specified confidence level $(1-\alpha)$. And such interval is named a $P$-content, $(1-\alpha)$-confidence Tolerance Interval (TI). The topic of the dissertation is the utility of tolerance intervals for various regression models. We begin with a discussion of tolerance intervals for linear and nonlinear regression models. We then propose a bootstrap method of constructing TIs for Tobit regression to deal with censored …


Novel Modelling And Inference Considerations Involving The Exponentially-Modified Gaussian Distribution, Yanxi Li Jan 2023

Novel Modelling And Inference Considerations Involving The Exponentially-Modified Gaussian Distribution, Yanxi Li

Theses and Dissertations--Statistics

The exponentially-modified Gaussian (EMG) distribution is well-suited for analyzing data with positive skewness due to its characteristic positive skew from the exponential component. Despite its popularity in various fields, the EMG distribution has only been analyzed for univariate data without any regression settings. To address this limitation, we developed a generalized EMG regression model with covariates by assigning parametric functional forms to some or all of the parameters in the EMG distribution that vary with values of the covariates. To further perform data-clustering on observation points, we propose a competing regression model where the error structure is assumed to be …


Adverse Childhood Experiences, Nicotine Dependence, And Depressive Symptoms Among A Community Sample Of People With Mental Illnesses, Bassema Abufarsakh Jan 2023

Adverse Childhood Experiences, Nicotine Dependence, And Depressive Symptoms Among A Community Sample Of People With Mental Illnesses, Bassema Abufarsakh

Theses and Dissertations--Nursing

Adverse childhood experiences (ACEs) pose a major public health issue as they are associated with poor mental and physical health outcomes. In the United States (US), more than 60% of adults report at least one ACE, and around 15% experienced four or more. Repeated exposure to ACEs stressors can convert ACEs to toxic stress by altering the brain's architecture and function. Evidence suggests that exposure to four or more ACEs, which are indicators of exposure to toxic stressors, is associated with nicotine dependence (ND) and depressive symptoms. Moreover, people with mental illnesses (MI) often have greater exposure to toxic stressors …


Effectiveness Of A Long-Acting Cocaine Hydrolase In Metabolizing Cocaine And Its Physiologically Active Metabolites, Linyue Shang Jan 2023

Effectiveness Of A Long-Acting Cocaine Hydrolase In Metabolizing Cocaine And Its Physiologically Active Metabolites, Linyue Shang

Theses and Dissertations--Pharmacy

Cocaine is a widely abused, hepatotoxic drug without an FDA-approved pharmacotherapy specific for cocaine addiction or overdose. Cocaine-induced toxicity in animals and humans is due to its multiple physiological effects on the central nervous system, cardiovascular system, etc. The toxicity of cocaine is highly complex, as its metabolites also contribute to the toxicity. Notably, the combination of cocaine and alcohol is common among drug users and can produce additional metabolites. Some of the metabolites are more toxic than cocaine itself. Hence, to develop an ideal therapeutic candidate, the candidate should not only account for cocaine but should also detoxify other …

Optimization Of Orally Bioavailable Inhibitors Of Defective In Cullin Neddylation 1 (Dcn-1), Leah Kovalic Jan 2023

Optimization Of Orally Bioavailable Inhibitors Of Defective In Cullin Neddylation 1 (Dcn-1), Leah Kovalic

Theses and Dissertations--Pharmacy

Ubiquitin (UB) and ubiquitin-like protein (UBL) pathways have emerged as important targets for oncology drug discovery based on the success of proteasome inhibitors (bortezomib or carfilzomib), E3 inhibitors, and the NEDD8 E1 inhibitor pevonedistat (MLN42924). Chemical inhibitors have also proven to be useful probes for identifying and dissecting multifactor UB and UBL regulatory networks. Toward this end, we have pursued approaches to target NEDD8 ligation to Cullins, through developing small molecule inhibitors of DCN1 (defective in Cullin Neddylation 1). DCN1 was discovered as a potentiating RBX1-dependent NEDD8-ligation, through recognizing the acetylated N-terminal methionine of the NEDD8 E2s UBE2M and UBE2F. …

Bioinformatic Analysis Of Proteomic And Genomic Data From Nsclc Tumors On Prognostic And Predictive Factors Of Immunotherapy Treatment, Mark Wuenschel Jan 2023

Bioinformatic Analysis Of Proteomic And Genomic Data From Nsclc Tumors On Prognostic And Predictive Factors Of Immunotherapy Treatment, Mark Wuenschel

Theses and Dissertations--Pharmacy

Recent lung cancer research has led to advancements in molecular immunology, resulting in development of small molecule inhibitors, or immune checkpoint inhibitors, that propagate an anti-tumor T cell response. Despite increased overall and progression-free survival with reduced adverse effects compared to traditional chemotherapy, treating advanced stage lung adenocarcinoma patients remains non-curative, and evidence of non-responders or tumor recurrence to immune checkpoint inhibitor therapy is growing. Also, compared to traditional chemotherapy, there is a lower percentage of patients who respond to small molecule inhibitors. In this analysis of proteomic and genomic data from The Cancer Proteome Atlas and Global Data Commons …

Maternal Occupation And Pediatric Brain Cancer In Kentucky, Mary Elizabeth Begley Jan 2023

Maternal Occupation And Pediatric Brain Cancer In Kentucky, Mary Elizabeth Begley

Theses and Dissertations--Epidemiology and Biostatistics

Pediatric brain cancer is a rare and potentially deadly diagnosis that affects children in Kentucky at a higher incidence than those nationally. Limited exposures in children early in life to warrant the development and progression of brain cancer point to the role parental exposures experienced in the period prior to conception and throughout pregnancy may play in its development. Many of these exposures may be experienced through occupation.

Data on a subset of pediatric brain cancer cases in Kentucky was compared to all cases diagnosed in the state from 1995 to 2019. Survey data of the study sample was collected …


Assessment Of Air Overpressure From Blasting Using Computational Fluid Dynamics, Cecilia Estefania Aramayo Jan 2023

Assessment Of Air Overpressure From Blasting Using Computational Fluid Dynamics, Cecilia Estefania Aramayo

Theses and Dissertations--Mining Engineering

Air overpressure is a shock wave that occurs when explosives detonate and travel through the air. This can cause damage and annoyance in mining blasts, making it a significant concern for the surroundings of the operation. Currently, the cube root scale distance is used to predict air overpressure, but this method has limitations. To accurately determine air overpressure behavior, a new method is needed. Computational fluid dynamics (CFD) is a reliable and advanced technique that can simulate and solve complex physical problems, including the behavior of air overpressure. In this thesis, two techniques, the bursting balloon, and total pressure boundary, …
