Secondary Traumatic Stress And Women Music Educators: A Phenomenological Study, Abigail Van Klompenberg

Theses and Dissertations--Music

Secondary traumatic stress (STS) is a phenomenon that affects individuals in helping professions, including educators. STS is a trauma disorder and results from one’s exposure to others experiencing trauma or who have experienced trauma. STS can affect physical health, well-being, and professional performance. Due to the profound effects of STS, there is a need for continued research to clarify this phenomenon in educators, specifically music educators. Furthermore, there is a need for research on STS in women due to women’s unique interactions with trauma and the potential for them to develop trauma disorders. At the time of this study, there …

Mammalian Dihydropyrimidine Dehydrogenase: Employing Transient State Kinetic Methods To Determine Catalytic And Inhibitory Mechanisms, Dariush Forouzesh

Dissertations

Dihydropyrimidine dehydrogenase (DPD) catalyzes the two-electron reduction of pyrimidine bases uracil and thymine as the first step in pyrimidine catabolism. The enzyme achieves this simple chemistry using a complex cofactor set including two flavins and four Fe4S4 centers. The flavins, FAD and FMN, interact with respective NADPH and pyrimidine substrates and the iron-sulfur centers form an electron transfer wire that links the two active sites that are separated by 56 Å. DPD accepts the common antineoplastic agent 5-fluorouracil (5FU) as a substrate and so undermines the establishment of efficacious toxicity. Though studied for multiple decades, a precise description of the …

Polyrhythmic Pathways: Using Bimanual Coordination Research To Develop A New Framework For Practice, Performance, And Pedagogy, Christian Swafford

Theses and Dissertations--Music

This study reviews and compares percussion literature pertaining to polyrhythms and scientific literature pertaining to bimanual coordination. There exists a gap in the pedagogical approach to polyrhythms, and there is much disagreement between common instructional methods, especially when considered against the findings of several bimanual coordination studies. The purpose of this study is to reveal insight to the percussion community that the learning of polyrhythms is facilitated by the brain in novel ways, and the uniqueness of this learning process requires a rethinking of the current pedagogical approach. Percussion articles, method books, popular literature, and music scores are surveyed alongside …

Does Euphrates Softshell Turtle Nest In Unfavourable Substratum? Description Of Nests From Euphrates River, Türkiye, Yusuf Bayrakci

Turkish Journal of Zoology

Nest site selection differs among species based on a characteristic crucial to the embryo's survival. The identified nest-site characteristics of the Euphrates softshell turtle highlight that these turtles, like their other soft-shelled relatives, highly prefer the sandy substrate, even pure sand, to nest. However, alteration and loss of natural habitats for many decades limited the suitable oviposition sites along the Euphrates River. This study presents the uncharacteristic nest-site choice and the nesting time of Euphrates softshell turtle for the first time. I discovered four nests, as well as six unhatched eggs in a nest on 20 August 2017. This discovery …

Effects Of Fungicide Programs And Lower Leaf Removal On Wrapper Leaf Production In Connecticut Broadleaf Cigar Wrapper Tobacco, Caleb Haygan Perkins

Theses and Dissertations--Plant and Soil Sciences

In recent years, there has been increased demand for natural leaf cigar wrappers. Kentucky and Tennessee have been of recent interest as a new area for Connecticut Broadleaf production. Initial production experiences have shown that late-season frogeye leaf spot caused by the pathogen Cercospora nicotianae Ellis & Everh. may result in ‘green spot’ in cured leaf and cause a significant problem for producers of Connecticut Broadleaf cigar wrapper tobacco. Field trials were established in 2021 at Princeton, KY and 2022 in Mayfield, KY and Springfield, TN to evaluate effects of fungicide programs and lower leaf removal on wrapper production and …

Multi-Omic Analysis Of Vegetative Propagation Induced Plant Rejuvenation In Grapevines: Implications For The Generation Of Locally Adapted Cultivars Using Epigenetics, Tajbir Raihan

Theses and Dissertations--Plant and Soil Sciences

Epigenetic memory of the growing environment is a process capable of increasing plants’ resilience to abiotic stimuli. The cultivated grapevine is a long-living perennial species with a large corpus of research suggesting that plant adaptation to the environment has implications for the selection of genetic material in a changing climate. Moreover, vine age has been traditionally correlated with enhanced fruit quality. Recent studies have shown that environment/age-acquired traits in grapevine (e.g., adaptation to the growing environment and fruit/wine quality, respectively) are associated with epigenetic mechanisms. These studies also indicate that of propagation type affects the maintenance/erasure of the acquired traits …

Species-Specific Microsymbiont Discrimination Mediated By A Medicago Receptor Kinase, Xiaocheng Yu

Theses and Dissertations--Plant and Soil Sciences

Legumes form a mutualistic partnership with nitrogen-fixing bacteria to meet their nitrogen requirements. This collaboration leads to the development of root nodules, offering an ideal environment for the bacteria to convert atmospheric nitrogen into ammonia. A salient aspect of this symbiotic relationship is host range specificity, such that nodulation capacity and nitrogen fixation efficiency differ significantly between different host-bacterial combinations. Understanding the genetic basis of this specificity could pave the way for strategies to overcome the host range barrier. Sinorhizobium meliloti and Sinorhizobium medicae are two closely related species that display differential symbiotic behaviors with legume plants of the Medicago …

Because U.S. community colleges focus on two-year degrees and workforce development, they were affected differently than their four-year counterparts. This study examined how academic administrators at different rural community colleges in Virginia, United States, perceived enrollment management practices that were implemented or changed due to the pandemic. This sequential explanatory study's first phase was quantitative and measured mid- to senior-level administrators' views of how the pandemic affected their colleges' enrollment management practices. The second qualitative phase resulted in five themes surrounding COVID-related enrollment …

Trait Impulsivity And Acute Alcohol Responses As Markers Of Binge Drinking In Young Adults, Holley Jamison

Theses and Dissertations--Psychology

Impulsivity, tolerance to alcohol-induced motor impairment, and high sensitivity to alcohol-induced disinhibition each have empirical support as markers of alcohol-related problems. However, research on alcohol response and personality-based markers of risk have remained largely independent lines of research. This dissertation examined how individual differences in these well-established markers may interact to additively contribute to heavy drinking.

Participants were 96 young adults (21-33 years old). with no history of AUD. They self-reported their drinking habits over the prior 90 days, and behavioral tasks measuring disinhibition and motor impairment were administered on two separate days following two alcohol doses (active [0.65 g/kg] …

Steady-State Regulation Of Secretory Cargo Export And Er Homeostasis By Inositol Trisphosphate Receptors And Penta-Ef-Hand Proteins, Aaron J. Held

Graduate Student Theses, Dissertations, & Professional Papers

Constant protein degradation and turnover necessitates constitutive secretion that delivers the correct mix of nascent proteins to their appropriate subcellular destinations. Cells thus exhibit steady-state secretion and the additional ability to adjust secretory flux, though we lack a clear understanding of this critical process. During secretion, the COPII coat is responsible for providing a balance of actively and passively selected ER cargos to enter the secretory pathway. Furthermore, Ca²⁺ -binding proteins have been implicated in regulating this process in response to Ca²⁺ signals. In Chapter 1, we review the secretory pathway and vesicular trafficking, with a focus on …

Molecular Studies Of Human Fibronectin, Precious Ann Lleva Nepomuceno

Graduate Student Theses, Dissertations, & Professional Papers

Fibronectin is an extracellular matrix glycoprotein that plays a major role in cell adhesion, cell growth and tissue organization. FN is comprised of three types of modular repeats – type I (FN1), type II (FN2), type III (FN3) – and a non-homologous variable region (V region) that can contain 0 to 120 amino acid residues depending on alternative splicing. Fibronectin contains several fibronectin type 3 (FN3) domains, which all have a β-sandwich structure composed of three-stranded (β-strands A, B and E) and fourstranded (β-strands C, D, F and G) β-sheets. FN3 domains are susceptible to mechanical unfolding, and it has …

Graduate Student Theses, Dissertations, & Professional Papers

Environmental variation plays an important role in shaping patterns of parasite and pathogen infections within ecosystems and populations. Effective management of wildlife diseases hinges on the detection of parasites and pathogens, followed by the identification of trends in infections that can be used for predicting their spread and implementing control measures. Beavers are ecosystem engineers and keystone species that serve as important sources of environmental variation. In North America, beavers are promoted for the conservation of imperiled taxa like amphibians which are facing declines driven by habitat loss, parasites, and pathogens. Beavers create diverse habitats that attract amphibians, but these …

Moments Of Excess: Type 1 Diabetes And The Myth Of Control In Adolescent Fiction For Girls, Michelle E. Legault

Master's Theses and Doctoral Dissertations

This thesis is the first academic work to analyze the stories of the Type 1 diabetic teen girls of adolescent fiction. In novels for adolescent readers, these girls are often White, female, heterosexual, and middle class—resulting in a collective disability narrative that portrays an “every girl” and lacks cultural or political dimensions. This thesis explores the narratives of five fictional teen protagonists with Type 1 diabetes. They are: Stacey McGill from the Baby-Sitters Club series by Ann M. Martin, Rachel Deering in Lurlene McDaniel’s Will I Ever Dance Again? (1982), Mackenzie “Zie” Clark in Sarah White’s Let Me List the …

“Hideous Things Have Happened Here”: Rape Myths, Rape Culture, And Healing In Adolescent Literature, Holly J. Greca

Master's Theses and Doctoral Dissertations

Adolescent novels about rape are one way to discuss rape and rape culture with a young audience. These novels can depict and challenge aspects of rape culture, including the myths that ultimately reinforce a culture hostile to rape victims. Considering the prevalence of rape in society at large, as well as its prevalence among adolescents, this thesis examines the elements of rape culture at play within adolescent rape novels, which can serve as pieces of activism as they give voice to adolescent survivors of rape. Adolescent rape novels explore the internal struggles of survivors as well as the external process …

Prediction Of Kinase-Substrate Associations Using The Functional Landscape Of Kinases And Phosphorylation Sites, Serhan Yilmaz, Filipa Blasco Tavares Pereira Lopes, Mark R. Chance, Mehmet Koyutürk

Faculty Scholarship

Protein phosphorylation is a key post-translational modification that plays a central role in many cellular processes. With recent advances in biotechnology, thousands of phosphorylated sites can be identified and quantified in a given sample, enabling proteome-wide screening of cellular signaling. However, for most (> 90%) of the phosphorylation sites that are identified in these experiments, the kinase(s) that target these sites are unknown. To broadly utilize available structural, functional, evolutionary, and contextual information in predicting kinase-substrate associations (KSAs), we develop a network-based machine learning framework. Our framework integrates a multitude of data sources to characterize the landscape of functional relationships …

Reducing Instances Of Staff Exposure To Ionizing Radiation In The Pacu, Christina Mcauliffe

Master's Theses and Capstones

Abstract

Background

On the Post Anesthesia Care Unit mobile X-Rays were necessary on site for confirmation of medical device placement. There was an unofficial procedure in place which consisted of announcing when an X-Ray was to be taken, and which bay it was taken in.

Local Problem

Upon observation it was noted that the mobile X-Ray unofficial procedure was only being adhered to for approximately 25% mobile X-Rays taken on the PACU, unnecessarily exposing staff to ionizing radiation. There was also no written procedure or standardized training policy available at the facility.

Unleashing Carbon Removal Technologies, Sierra Apillanes, Alexa Penalosa

Colorado Environmental Law Journal

Mounting climate change concerns are driving unprecedented interest in carbon dioxide removal technologies. Unlike carbon capture strategies, which trap carbon dioxide at specific emission points such as power plant smokestacks, carbon removal technologies directly remove carbon dioxide from the ambient atmosphere. Fossil fuel industry stakeholders have championed carbon capture for years as a means of reducing carbon emissions while continuing the nation's heavy reliance on carbon-intensive energy sources. This focus on promoting carbon capture has delayed the development of policies specifically aimed at promoting carbon removal. As a result, humankind has yet to effectively leverage carbon removal technologies in the …
