The Effect Of Voluntarily Disclosing An Earnings Surprise On Management Operating Decisions, Jonathan Gay

Theses and Dissertations

Prior research extensively examines the external implications of voluntarily disclosing an earnings surprise, yet the internal implications remain understudied. Using two experiments, I examine whether the preemptive voluntary disclosure of an earnings surprise influences management operating decisions. Drawing upon mental accounting and the realization effect, I predict that managers are more likely to make inefficient operating decisions when an earnings surprise is expected and that a quantitative, but not qualitative, voluntary disclosure will mitigate this value-sacrificing behavior. I find that managers are more likely to make inefficient operating decisions when a negative, but not a positive, earnings surprise is expected …

Exploring The Immune System’S And Silybin’S Impact On Cancer Cachexia, Patrice Cunningham

Theses and Dissertations

Cancer cachexia is a complex syndrome that is characterized by the unintentional loss of body weight with or without fat loss. During cancer cachexia, there is an increase in inflammation consistent with various inflammatory cytokines such as tumor necrosis factor-alpha (TNF-α), Interleukin-1 beta (IL-1β ), and interleukin-6 (IL-6); all of which are known to increase proteolysis and aid in the progression of muscle loss and weakness. Immune cells such as macrophages are increased during cachexia and are known to have varying effects on muscle inflammation, regeneration, and the progression of fibrosis in a disease state. However, therapies aimed solely at …

Theses and Dissertations

The United States is experiencing a maternal health crisis, which disproportionately affects Black women. Black women die from pregnancy-related causes two to three times as often as their White counter parts, and the majority of maternal death are preventable. In recent years, public health and national governing authorities have devoted resources to monitoring the health crisis and raising the public’s knowledge of warning signs; however, maternal mortality rates continue to rise. Noted contributors to Black maternal mortality include, but are not limited to, racism, delayed treatment and response to health emergencies, and lack of social and emotional support during childbirth, …

Assessing Obgyn Residents’ Knowledge, Attitudes, And Current Practices For Carrier Screening, Aubrey Morgan Surian

Theses and Dissertations

Obstetricians and gynecologists (OBGYNs) are the main providers that order carrier screening on a regular basis, so it is important to understand their knowledge, attitudes, and current practices regarding this screening. There are two primary professional organizations that have established practice guidelines for carrier screening, the American College of Obstetrics and Gynecology (ACOG) and American College of Medical Genetics (ACMG). With the growth of pan-ethnic carrier screening, these guidelines have become remarkably different. This study aimed to assess resident OBGYN’s utilization of pan-ethnic carrier screening, discern any discrepancies between knowledge, attitudes, and current practices, identify possible practice resources that may …

Ecoaldeas As A Critical Dystopic Landscape, Meagan Elizabeth Cobb Heath

Theses and Dissertations

This dissertation centers on the following three dystopic works from Spain: the novella “2084. Después de la Revolución” by Elia Barceló, the novel Cenital by Emilio Bueso, and the Netflix series La valla directed by Daniel Écija. I contend that the ecoaldea in each of these works is not merely a setting, but rather is an experimental space from which solutions to current crises (primarily the climate crisis) can be created and tested. The intersectional theoretical framework used to analyze this assertion is based on science fiction, dystopic studies, ecocriticism, and postgrowth imaginaries. Each chapter addresses: (1) how the society …

Reading Ecogothic Memory In Contemporary Southern Swamp Novels, Megan Caroline Brockhard Knight

Theses and Dissertations

The ecogothic is a lens through which to engage memory, southern constructivism and identity, environmental intervention, and the literature of the American Southeast. This project establishes a framework of literary criticism that defines the ecogothic, interprets memory as truth imagined, and identifies the position of memory in the environment as a construction with which it is necessary to grapple to understand identity. This framework, compiled of existing and original scholarship, is then applied to three contemporary swamp narratives written by three different southern women writers. The swamp setting creates a unique microcosm of gothic liminality, neither fully land nor water, …

Estuarine Microbial Community Composition And Efficiency Changes In Response To Vibrio Parahaemolyticus Exposure, Sarah Mulligan

Theses and Dissertations

Vibrio parahaemolyticus is a pathogenic bacterium whose full impact on natural estuarine phytoplankton communities has not been fully resolved. The primary goal of this research was to test how the addition of V. parahaemolyticus to a natural estuarine microbial community would impact the other microbes present. We hypothesized V. parahaemolyticus exposure would reduce phytoplankton biomass and alter the composition of phytoplankton and bacterial communities. Experimental bioassays (60h) were used to assess the effects of the presence of V. parahaemolyticus . Samples for measurements of chemotaxonomic photopigment concentrations, 16S sequencing-based community composition, photosynthetic efficiency, cell density, and V. parahaemolyticus abundance were …

Four Essays On Banking, Bank Management, And Bank Lending, Jiarui Guo

Theses and Dissertations

This abstract synthesizes findings from four studies examining the liquidity creation, bank-borrower relationships, corporate capital structure, and managerial impact on firm performance, particularly within the context of banking and financial crises, including the COVID-19 pandemic.

The research first identifies the dual shocks of the pandemic—disease and policy-driven (government shutdowns)—on bank liquidity creation. I find that these shocks prompted banks to reallocate liquidity creation from assets (decreasing loans) to liabilities (increasing liquid deposits), which reduced profits and heightened risks.

In exploring bank-borrower relationships, the study highlights the role of banks in utilizing soft private information, such as the moral character of …

Histories Of Stress: A Life Course Approach To Population Health In Late Medieval And Early Modern Berlin, Emily Brennan

Characterizing The Role Of The Escherchia Coli Monothiol Glutaredoxin, Grxd, As An Iron-Sulfur Cluster Carrier Protein, Claire Elizabeth Fisher

Theses and Dissertations

Iron-sulfur (Fe-S) clusters are important cofactors with a primary role of electron transport that are required by proteins involved in wide range of biological pathways such as respiration, photosynthesis, and DNA repair. In Escherichia coli (E. coli), the assembly and transfer of these clusters to their target apo-protein is a highly coordinated process encoded by the multiprotein systems iscRSUAhscBAfdx and sufABCDSE operons. These clusters are assembled on a scaffold protein, where they are then transferred to a carrier protein that will deliver the cluster to the target apo-protein. The Isc and Suf systems contain their own carrier proteins IscA …

In The Search Of Cosmopolitan Literacies: A Case Of Formerly Expatriated Language Teacher, Asiye Demir

Theses and Dissertations

Cosmopolitanism refers to becoming a world citizen who can live harmoniously with different cultures. Today, our classes in the United States have become diverse daily. While we teach students who can speak more than one language, our teachers are primarily monolingual and monocultural. Hence, teachers who can speak multiple languages are celebrated in the system (Pacheco et al., 2019). Expatriation refers to teacher mobility that can entail learning other languages and being exposed to different cultures. Expatriation, as a form of travel, is an essential construct for cosmopolitan literacies because cosmopolitan dispositions can be developed through traveling (Molz, 2006). Thus, …

Exiting Inflation With A Smooth Scale Factor, Harry Oslislo

Theses and Dissertations

The expectation that the physical expansion of space occurs smoothly may be expressed mathematically as a requirement for continuity in the time derivative of the metric scale factor of the Friedmann–Robertson–Walker cosmology. We explore the consequences of imposing such a smoothness requirement, examining the forms of possible interpolating functions between the end of inflation and subsequent radiation- or matter-dominated eras, using a straightforward geometric model of the interpolating behavior. We quantify the magnitude of the cusp found in a direct transition from the end of slow roll inflation to the subsequent era, analyze the validity several smooth interpolator candidates, and …

Dynamic Response Evaluation Of Loose Gravelly Soils In Centrifuge Modeling Experiments, Siwadol Dejphumee

Therefore, understanding of the gravelly soil behavior under seismic load is critical for assessing the resilience of infrastructure located in seismically active regions. To date, only a few experimental research studies have focused on the dynamic response of gravelly soil, and these studies …

Native American Nationalism: Chickasaw Identity And The Music Of Jerod Impichchaachaaha' Tate, Austin Davis

Theses and Dissertations

Native American nationalism in classical music has yet to be seriously researched and is not taught in music academia. One of the more well-known contemporary Native American composers is Chickasaw composer Jerod Impichchaachaaha’ Tate (b. 1968). Throughout his career, Tate has explored and expressed his identity as a Native American and Chickasaw citizen through his music. As a result, his compositional output is a rich resource for examining what Native American nationalism in classical music looks like and how it is utilized in his works.

In this document, I analyze three of Tate’s pieces written for orchestra: Tracing Mississippi, Ghost …

Impaired Waters: New Treatments And Improved Methods For Pfas And Algae Toxins, Alexandria Forster

Theses and Dissertations

Per- and polyfluoroalkyl substances (PFAS) are high-profile environmental contaminants, many having long persistence in the environment and widespread presence in humans and wildlife. Following phase-out of perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) in North America and restrictions in Europe, PFAS replacements are now widely found in the environment. While liquid chromatography (LC)-mass spectrometry (MS) is typically used for measurement, much of the PFAS is missed. To more comprehensively capture organic fluorine, we developed sensitive and robust methods using activated carbon adsorption, solid phase extraction, and combustion ion chromatography (CIC) to measure total organic fluorine (TOF) in industrial wastewaters, river …

Dysregulation Of Dopamine Dynamics Through Monoamine Transporters By The Hiv-1 Protein Transactivator Of Transcription, Sarah Davis

Theses and Dissertations

Prevalence of HIV-1 Associated Cognitive Disorders (HAND) persists in the era of combined antiretroviral therapies, causing impaired memory, motor function, and decreased quality of life. Evidence from clinical samples of persons with HAND has implicated dopamine, as well as the HIV-1 viral protein transactivator of transcription (Tat) as key molecules associated with disease progression. Through molecular modeling, in vitro and in vivo mutagenesis our lab has characterized Tat as a negative allosteric modulator for monoamine transporters, including the dopamine transporter (DAT), vesicular monoamine transporter (VMAT-2), and norepinephrine transporter. While this work has shed light on how Tat impacts the function …

State Estimation And Prediction Based On Simplified First Principle Model Of Lithium-Ion Batteries In Lebesgue Sampling Framework, Enhui Liu

Use Of Improvement Science To Build The Instructional Capacity Of Faculty In A Community College, Marianne Yohannan

Theses and Dissertations

Up to 78% of Science, Technology, Engineering and Mathematics (STEM) students experience poor academic achievement as defined by course grades of D, F and W in college. Students entering these fields are often not prepared (Chen & Soldner, 2013) and struggle to succeed in gateway STEM courses, with one-third of them possibly failing (Freeman et al., 2011). The success rates are lower among first-generation, low-income, and underrepresented minoritized groups (Doerschuk et al., 2016). At Tri-County Technical College, 30-40% of introductory biology students are unsuccessful and receive low grades (Institutional Research, n.d.). Low academic achievement has a huge impact on our …

Associations Between Infant Vagal Regulation, Early Social Communication, And Socidemographic Risk, Tessa Djiko

Theses and Dissertations

Respiratory sinus arrythmia (RSA), a measure of parasympathetic nervous system activation, has been linked to socioemotional and language development (Porges, 2007; Thayer & Lane, 2000). Children diagnosed with autism spectrum disorder (ASD) show lower RSA (Patriquin et al., 2011) while both children with ASD and children from lower SES backgrounds show differences in early social-communication development (Jones-Mason et al., 2018). However, little is known about interactions between sociodemographic risk and physiological regulation within the context of ASD and social-communication development. The present study addresses this gap by examining the relationship between RSA (as indexed by RSA suppression and resting-state RSA), …

Molecular And Hybrid Catalysts For Selective Hydrodeoxygenation Of Lignin Model Compounds, Jacob G. Tillou

Theses and Dissertations

Lignin is a highly aromatic, branched polymer and could be utilized as a renewable source of liquid fuel. The advent of “lignin-first” depolymerization processes have allowed for the high-yield isolation of oxygenated aromatic monomers from lignin. These oxygenated aromatic compounds are lower in energy and stability than their deoxygenated counterparts. Selective deoxygenation of these compounds would result in stable, higher value liquid fuels. Using molecular catalysts, selective deoxygenation, or hydrodeoxygenation (HDO), of lignin-derived compounds in the presence of hydrogen is possible.

Immobilization of these molecular catalysts on metal oxide surfaces eliminates the possibility of bimolecular decomposition and allows for easier …

Enslaved Women: Reproductive Choices And Medicine, Adedoyin Adekunle

Theses and Dissertations

Enslavement in the American South persisted as a form of subjugation that endured into the nineteenth century. The origins of slavery stemmed from enslavers’ aspirations for dominance. This compelled displacement involved the removal of Africans from their native lands and their subsequent transport as chattels to America. Slavery gave rise to paternalism, an attempt to justify exploitation to resolve the fundamental contradiction inherent in slavery. Paternalism gave rise to the false idea of ultimate submission, which historians have agreed that most enslavers never attained because of slave resistance. However, the study of slave resistance had been primarily focused on enslaved …

Addressing A Crisis In Nursing Practice: Exploring The Impact Of Multimedia Case-Based Learning On The Clinical Judgment Of Undergraduate Nursing Students, Macy Jenette Bennett

Theses and Dissertations

Clinical judgment is a priority nursing skill to ensure the delivery of safe and effective nursing care. New graduate nurses and nursing students lack the clinical judgment skills that are necessary for entry-level nursing practice. Nurse educators must therefore implement teaching strategies that facilitate clinical judgment. This study evaluated the clinical judgment of undergraduate nursing students after the implementation of multimedia case studies related to the concept of perfusion. Two research questions guided this study: (a) in what ways do undergraduate nursing students demonstrate clinical judgment after completing a series of perfusion-related multimedia case studies and (b) to what extent …
