Identification And Characterization Of Genetic Elements That Regulate A C-Di-Gmp Mediated Multicellular Trait In Pseudomonas Fluorescens, Collin Kessler

Electronic Theses and Dissertations

Microbial communities contain densely packed cells where competition for space and resources are fierce. These communities are generally referred to as biofilms and provide advantages to individual cells against immunological and antimicrobial intervention, dehydration, and predation. High intracellular pools of cyclic diguanylate monophosphate (c-di-GMP) cause cells to aggregate during biofilm formation through the production of diverse extracellular polymers. Genes that encode c-di-GMP catalytic enzymes are commonly mutated during chronic infections where opportunists display enhanced resistance to phagocytosis and antibiotics. Our lab uses an emergent multicellular trait in the model organism Pseudomonas fluorescens Pf0-1 to study the emergence of c-di-GMP mutations …

“I Hear You”: Exploring The Lived Experience Of Counselors’ Empathic Response To Clients When Conducting Telephonic Counseling During Covid-19, Michael Sickels

Electronic Theses and Dissertations

Dissertation supervised by Dr. Debra Hyatt-Burkhart

This study sought to unearth the lived experience of counselors empathically responding to clients via telephonic counseling during COVID-19. The term empathic response refers to as attending to the emotional and mental state of another person in a way that is attuned with the feelings and meanings of the individual’s experience. There are few studies that have assessed the merits of telephonic counseling, and even fewer that have examined counselors’ empathic response to clients through this medium.

To uncover the lived experience of the target population, the participants of the study were purposefully selected …

Theory Of Aqueous Solvation: Uninterrupted, Cyclic Hydrogen-Bonding Essential For Accurate Keto-Enol Energies And Grotthuss Tautomerism Of Acetone, Mark Recznik

Electronic Theses and Dissertations

Keto-enol tautomerization (KET) is a fundamental process impacting a range of molecular phenomena in organic and biochemistry. However, the accurate computation of solution-phase KET energies remains a challenge, even for prototypical acetone.

In Part I, keto-enol tautomers of acetone were incorporated into solvent clusters that interact via uninterrupted, cyclic hydrogen-bonding (UCHB) networks. An empirical model was created to predict accurate KET energies, E_taut, of simple carbonyl compounds. Based on the availability of experimental data and structural simplicity, acetone was selected as a prototype. A discrete-continuum strategy was employed – accounting simultaneously for local noncovalent interactions and bulk-phase effects …

Without Permanence: Mapping Multi-Genre, Cross-Disciplinary Frameworks For Trans* Studies, Jesse Jack

Electronic Theses and Dissertations

This project takes a cross-disciplinary and multi-genre approach to Transgender (Trans*) Studies to proliferate diverse and ambiguously-gendered representations of trans* experiences across time. It identifies the emergence of rhetorical intertextuality in recent trans* literatures as a discursive response to the biopolitical regulation and erasure of ambiguously-gendered, trans* experiences. It identifies the intersecting influences of twentieth- and twenty-first-century medical paradigms, surveillance apparatuses, popular trans* autobiographies, and archives in representing and exceptionalizing certain trans* experiences over others. In contrast, this project engages in a close reading of Pajtim Statovci’s Crossing (2016) and Andrea Lawlor’s Paul Takes the Form of a Mortal Girl …

The Combined Benefits Of Dispositional Mindfulness And Trait Self-Compassion As Potential Buffers Of The Effects Of Perceived Stress On Sleep Quality In College-Aged Young Adults., Jackie Ma

Electronic Theses and Dissertations

Using a nonclinical sample of 108 undergraduates between the ages of 18 to 25 years old, this cross-sectional study investigated the relationship between dispositional mindfulness (as measured by the Five Facet Mindfulness Questionnaire; Baer et al., 2006) and sleep quality (as measured by the Pittsburgh Sleep Quality Index; Buysse et al., 1989). Second, it evaluated the association between trait self-compassion (as measured by the Self-Compassion Scale; Neff, 2003b) and sleep quality. Third, it aimed to test for an interaction effect between dispositional mindfulness and trait self-compassion as buffers against the adverse effects of perceived stress on sleep quality. Results showed …

Voices Of The "Served": Community Resident Perspectives On International Service-Learning In Peru., Adam C. Stieglitz

Electronic Theses and Dissertations

The purpose of this study is to capture and share community resident perspectives on international service-learning (ISL). Community resident voice is largely underrepresented in ISL scholarship and practice. Conversely, research on student outcomes is ubiquitous, which generally makes student benefit a predominant consideration in ISL program design. Consequently, scholars have criticized ISL programs for being inherently extractive and even an embodiment of modern-day colonialism. This study aims to address this critique by offering a robust representation of community residents’ perspectives for how to responsibly design ISL programs. This study used action research methodology to capture community resident voices who participate …

Targeting Pathological Changes In The Gut Protects The Cns From Neuropathology., Benjamin Tyler Charpentier

Electronic Theses and Dissertations

There is growing evidence that the health of the gut microbiome (GM) has an important role on multiple host organ systems. Ethanol-related neuropathologies and Alzheimer’s disease (AD) currently have no effective clinical treatment. Therefore, we developed a novel mouse model of fecal matter transplantation (FMT) utilizing the microbiome from alcoholic hepatitis (AH) patients, characterized by a loss of butyrogenic potential. Minimal neuroinflammation occurred in AH-FMT mice, but significant increases in the endoplasmic reticulum stress response (ERSR) across the majority of neurons in the prefrontal cortex and hippocampus were observed. In the cerebellum, Purkinje cells were specifically affected. Targeting the loss …

Characterization Of Microbotryum Lychnidis-Dioicae Secreted Effector Proteins That Manipulate Its Host Plant, Silene Latifolia., Ming-Chang Tsai

Electronic Theses and Dissertations

The smut fungal species Microbotryum lychnidis-dioicae is an obligate phytopathogen colonizing the plant host, Silene latifolia. A significant feature of M. lychnidis-dioicae infection is that the fungus can replace pollen on the anthers of susceptible host plants with fungal teliospores, thus earning the fungus the name: anther smut disease of flowers. The fungus synthesizes and secretes effector proteins into the cells of the plant host during infection, and the protein-protein interactions may interfere with and modify metabolism, plant development, and gene expression of the host to allow fungal colonization. Two potential fungal effector proteins, MVLG_06175 and MVLG_05122, were identified …

Treating Active-Duty Military Members: Best Practices For Common Mental Health Diagnoses Across The Dod, Leah Lawson

Electronic Theses and Dissertations

Due to varying service experiences, active-duty service members endure military related stressors in addition to everyday life stressors. As a result, their risk of mental illness onset increases. Considering that many of the stressors and events are unique to military personnel, it is important to identify best-practice interventions for working with this population opposed to employing civilian best practices. The purpose of this study was to determine what treatment interventions are best-practice when working with active-duty military members diagnosed with the three most common mental disorders (e.g., adjustment disorder, depressive disorders, anxiety disorders) across the Department of Defense (DoD). This …

The Ties That Bind: Creole Networks And Reform In New Granada During The Age Of Revolution, 1780-1811, Philip John Baltuskonis

Electronic Theses and Dissertations

At the beginning of the nineteenth century, Spanish Americans were immersed in a practical Enlightenment that aimed to improve society during the Age of Revolution (1780-1850). In the city of Santafé de Bogotá, elites comprised of Spaniards and creoles (Spaniards born in the Americas) joined in scientific expeditions, higher education, creating newspapers, and proposing economic and educational reforms that all promised to bring prosperity to the Viceroyalty of New Granada (present-day Colombia, Venezuela, Ecuador, and Panama). Rather than a source of major confrontation, elites’ activities aligned with the Spanish Crown’s interest in turning its American kingdoms into centers of wealth. …

Seeing Queer Joy In Mississippi: Pride Parades In Tupelo, Starkville, And Oxford, Ellie Campbell

Electronic Theses and Dissertations

In May of 2016, Oxford, Mississippi, held its first LGBTQ+ Pride parade in recent memory. That first Oxford Pride was part of a wave of LGBTQ+ celebrations that began in the state in 2015 and 2016 and continue to the present day. Though the pandemic forced many to cancel or go online, communities across Mississippi have continued to organize Pride parades and other celebrations of LGBTQ+ identities since 2015, a marked contrast from earlier periods. In a state often depicted as actively hostile to queer people, these Pride events make queer southern communities visible in new ways, while also revealing …

Adding Fuel To The Flames? Foreign Aid Bypassing And Political Support In Recipients, Obaida Shammama

Electronic Theses and Dissertations

Foreign aid scholars argue that donors outsource development assistance to non-governmental organizations (NGOs) because of poor governance and capacity constraints in aid recipients. But what shapes recipient citizens’ preference for aid delivery channels? How does foreign aid bypassing affect government support in recipients? Drawing on the logic of selective evaluation and micro-performance hypothesis, I contend that greater concern for quality of governance will positively influence support for foreign aid channeling through NGOs among aid recipients. Additionally, favorable attitude towards foreign aid bypassing will be negatively associated with government approval. Finally, an increase in foreign aid bypassing will be associated with …

The Hope For Peace & The Case For War In The Postwar Soviet Union, Shawn Cecconi

Electronic Theses and Dissertations

The postwar Soviet Union remained militarized and failed to reform itself because of its ideological concerns against the West and its new satellite states, all at the cost of the Soviet people. This analysis will compare the Soviet government’s external focus and the Soviet people’s domestic problems in the aftermath of the Second World War. The country’s ideological, military, and imperial concerns abroad emphasized militarization over domestic revitalization. The Soviet people widely expected significant action from their government to remedy economic and political issues. The Soviet government nevertheless committed itself in focusing on outside concerns regardless of the harsh reality …

Validation Of The 40 Hz Auditory Steady State Response As A Pharmacodynamic Biomarker Of Evoked Neural Synchrony, Muhammad Ummear Raza

Electronic Theses and Dissertations

Schizophrenia is a troubling and severe mental illness that is only incompletely treated by currently available drugs. New drug development is hindered by a scarcity of functionally relevant pharmacodynamic biomarkers that are translatable across preclinical and human subjects. Although psychosis is a major feature of schizophrenia, cognitive and negative symptoms determine the long-term functional outcomes for patients. Stimulus-evoked neural synchrony at gamma (~ 40 Hz) frequency plays an important role in the processing and integration of sensory information. Not surprisingly, schizophrenia patients show deficits in gamma oscillations. NMDA receptor (NMDAR) activation on fast-spiking parvalbumin-positive interneurons is deemed important for the …

An Investigation Of The Relationship Between Teachers’ Personal Epistemologies And Their Self-Efficacy About Culturally Responsive Classroom Management, Tahani Ahmed

Electronic Theses and Dissertations

Diversity is now an essential matter in US public schools. For the first time in America's history, students of color will constitute a majority of the public school enrollment; on the other hand, most early childhood and elementary teachers remain monolingual, white, middle-class females (Hussar & Bailey, 2019). The demographic mismatch between students and teachers presents a critical concern for teacher preparation programs (Banks et al., 2005; Gay, 2018; Muñiz, 2019). Therefore, this study proposed that understanding the relationship between pre-service teachers' epistemological beliefs and their culturally responsive classroom management self-efficacy illustrated factors that may improve their teaching concept toward …

"Agitate, Agitate, Agitate": Stories From Mississippi Valley, Parchman, And The Largest Mass Arrest Of Students In U.S. History, Katherine Aberle

Electronic Theses and Dissertations

In the midst of the turbulent and sometimes violent unrest culminating in the fatal shootingsat Kent State University and Jackson State College in 1970, there is another story of black student activism that has been all but erased from public memory. In February 1970, the largest mass arrest of students in U.S. history took place at a relatively obscure small-town college in the Mississippi Delta. That winter, enrollment at Mississippi Valley State College was barely 2000 students, but on February 11, 1970, almost 900 students, nearly half the student population at the historically black college, would be arrested and find …

The Self Compassionate Side Of Awe: The Relationship Between Awe And Self-Compassion Via Self-Diminishment And Connectedness, Rachael Marie Cavallaro

Electronic Theses and Dissertations

Given that having a self-compassionate attitude is linked to positive psychological functioning, it is important to identify factors that promote self-compassion. Several self-transcendent experiences and emotions, which perceptually blur the lines between the self and others, predict self-compassion. Awe, a mixed-valance emotion defined by vastness and need for accommodation, seemed a likely candidate to promote self-compassion, as it is also a self- transcendent emotion with intra and interpersonal functions (e.g., increased humility, openness, and connection) that theory and empirical research has linked to self-compassion. Thus, we hypothesized that awe would promote self-compassion both directly and indirectly via boosted feelings of …

Bridging Souths: Interdisciplinarity And Knowledge Production In Southern Studies, Matthew David Streets

Electronic Theses and Dissertations

This thesis examines the viability of southern studies, a regional studies project on the study of the U.S. South, as an academic field of study and institutionalized site of multi-, inter-, and transdisciplinary knowledge production. Southern studies has undergone numerous turns and paradigm shifts since its institutionalization in the 1970s. These ontological, epistemological, and methodological developments have reoriented the objectives of interdisciplinary knowledge production. Despite the present permeability of disciplinary boundaries, the institutional structure and its racial, capitalist, and disciplinary hierarchies hinder communication and collaboration across disciplines and fields and between the “ivory tower” and “real world.” Understanding the impact …

Performance Cultures And Black Atlantic Literature, 1750-1833, Chinaza Amaeze Okoli

Electronic Theses and Dissertations

This dissertation approaches performance cultures as integral components of early black Atlantic writing, and considers how meaning is produced at the intersection of writing and vernacular performance. It asserts that black writers, in their portrayal of performance practices, encode avenues and strategies for accessing other black voices in their communities. Pairing writing by black authors and a selection of comparable vernacular practices, my dissertation examines how these forms signify upon each other, offering new contexts for interpreting the black experience in the long eighteenth century. In exploring this thesis, my work approaches Olaudah Equiano’s narrative as illustrative of the ways …

Growing Concerned: How Societal Stress Relates To Plants In The Home, Trenton W. Birdwell

Electronic Theses and Dissertations

Design trends are constantly in flux, but the reasons why people prefer new trends are not readily apparent. This thesis brought together multiple aspects of interior design to investigate how design has changed. After a review of available studies, the researcher decided to focus on natural design in homes because this area has previous research upon which to build. This study compared data to examine how stress in America relates to plant imagery. The research questions asked what, if any, relationship exists between societal stress and the use of plants, plant-like objects, and window views.

Measures of stress included hospitalization, …
