Given the impacts that virtual communication has had on connectivity, and speech patterns this research attempts to find if those impacts have been consistent in its application to the IPDA. The study uses a quantitative survey methodology …

Narratives Of Existence And The Narrative Existence: Ontological Unity In The Border Trilogy And Quantum Theory, Rebecca Leigh Mcintosh

Electronic Theses and Dissertations

Because the humanities and the sciences approach philosophical questions in contrasting ways, the study of literature and the study of physical science are often viewed as unrelated realms of scholarly inquiry. Science aims to provide a methodological approach for gathering knowledge about the world, while the humanities focus on criticism or analysis of cultural artifacts. However, even though the conceptual frameworks applied in scientific study and literary study are often incompatible or remarkably divergent, their methods for conceptualizing and transmitting ideas are the same, for humanity understands the world and experience of this world through narratives composed of referential metaphors. …

Adverse Birth Outcomes: Investigating The Role Of Nativity And Perceived Racial Discrimination Among Black Mothers Enrolled In Des Moines, Iowa Healthy Start., Kendria Kelly-Taylor

Electronic Theses and Dissertations

Birth outcomes for Black women in the United States (US) are disproportionately worse in comparison to non-Black women, even when controlling for potential confounders. Existing studies suggest foreign-born (FB) Black women present better birth outcomes in comparison to US-born (USB) Black women. Also, the longer FB Black women live in the US, the more their perinatal health advantage diminishes. Racial discrimination has been hypothesized as a potential reason for this decline. This dissertation investigates the relationship between nativity and adverse birth outcomes while also exploring how the reporting of racial discrimination impacts birth outcomes among FB and USB Black mothers …

Land Tenure And The Urban Institutional Politics Of Sustainability: How Sustainability "Lands" In The Relationships Between Global North And South Contexts., Lindsey Connors

Electronic Theses and Dissertations

Sustainability is not simply a moral concept but is essential for human survival, and the tensions inherent in sustainable development bear repercussions that are increasingly placed onto the poor and powerless (Redclift 1987). While sustainability has become a relevant concept for urban knowledge and research especially in the global South, much of our urban sustainability knowledge is shaped by research and typologies from the global North (Nagendra et al. 2018; Parnell & Robinson 2017; Roy 2005). This dissertation considers the spatial transferability of sustainability knowledge from a relational perspective (Massey 2002). Sustainable development can be understood from this perspective as …

Peer Perceptions Of Parent-Students Seeking Higher Education, Alexandria M. Wall

Electronic Theses and Dissertations

With a growing number of parents pursuing academia, it is imperative that researchers understand the social environment in which parent-students function. Stereotypes of parent-students may be held by peers, faculty, and other educational supervisors. Across two previous independent studies, evidence and rationale were provided to suggest that both positive and negative perceptions of parent-students exist, with noted differences between gender. The purpose of the current 2x2x2 between-subjects study was to analyze the social perceptions of students enrolled in higher education as varied by parenthood status, age, and gender. The social perceptions included measures accounting for perceptions of intelligence and academic …

Paragons Of Art And Nature In Eighteenth-Century British Aesthetic Theory., Eduard Ghita

Electronic Theses and Dissertations

This dissertation examines the interaction of nature and art as objects of aesthetic appreciation in eighteenth-century Britain, with special emphasis on the aesthetic theories of Anthony Ashley-Cooper-3rd Earl of Shaftesbury, Joseph Addison, and William Gilpin. Despite its openness to explore principles of aesthetics and concepts, such as beauty and sublimity, that were common to both nature and art, modern aesthetic theory framed the relation of art to nature hierarchically, an aspect captured by the term ‘paragon’. In this dissertation I trace a movement away from theories in which the superiority of nature to art was recognized (chapter 2 on Shaftesbury’s …

Investigation Of Light Management Strategies And Photochemistry Of Si/Tio2 Tandem Microwire Slurries For Solar Hydrogen Generation., Saumya Gulati

Electronic Theses and Dissertations

The intermittent nature of the Sun makes it difficult to use it as a primary source of electricity and often needs to be supplemented by electricity from the grid which comes from fossil fuels. This motivates the need for solar energy storage. Photoelectrochemical (PEC) water-splitting has been explored as a means to convert solar energy into hydrogen (and oxygen), which can be stored as fuel. The current method of coupling PV and electrolyzer units has been widely commercialized, however, the cost of H₂ generated is far from the target of $1/kg set by the DOE under the Energy EarthShot …

Rainforests Of The Mind: Conceiving Transnational Composition From A Mobilities Perspective On Knowledge., Tobias Lee

Electronic Theses and Dissertations

This research project stems from my experience teaching academic writing at the state university in Qatar. To investigate the factors overdetermining the deeply standardized curriculum there, I draw on scholarship in mobility studies, political economy, and the history both of Qatar and of composition instruction in the US, from which the curriculum is drawn. These explorations ultimately lead me to comment on the fraught enterprise of subjecting writing and language to commodification, which I identify as part of broader trends characterizing neoliberal economic globalization. To further develop this critique, I conduct a critical multi-sited autoethnographic study that questions preconceived notions …

An Analysis Of The Effects Of Certified Electronic Health Records On Organizations And Patients., Picandra Elzie

Electronic Theses and Dissertations

The growing technological advancement of electronic health records can become an issue with quality and electronic patient information exchange if hospitals do not adhere to federal guidelines. It is recommended that hospitals utilize certified electronic health records (EHRs) to receive financial incentives. This certification is supposedly also associated with the quality of the EHR itself. The certification process is criticized for allowing EHR vendors to meet a set of limited functions known in advance. EHRs can affect healthcare quality and electronic health information exchange. This dissertation explored what is known about the effects of certified EHRs on length of stay …

Perineuronal Nets Are Not Required To Close The Critical Period For Ocular Dominance Plasticity., Emily Crouse

Electronic Theses and Dissertations

In the developing visual system, a transient critical period demarcates when neural circuits are most sensitive to visual experience. In the mouse, the critical period occurs between approximately postnatal day(P) 19 to 32. Closing one eye (monocular deprivation, MD) within the critical period shifts ocular dominance (OD) to be more responsive to the open eye. Nogo-66 Receptor 1 (NGR1) limits OD plasticity to the critical period yet it remains unknown how OD plasticity propagates through primary visual cortex or by which mechanisms NGR1 utilizes to confine said plasticity. In primary studies, NGR1 was selectively deleted in different cortical layers to …

Irreversible Electroporation Potentiates Beta Glucan Induced Trained Innate Immunity: A Novel Combination Treatment For Pancreatic Adenocarcinoma., Matthew Woeste

Electronic Theses and Dissertations

Pancreatic cancer (PC) is a challenging diagnosis yet to benefit from advances in immune oncologic treatments. Irreversible electroporation, a non-thermal method of tumor ablation, is used in treatment of select patients with locally advanced unresectable PC and has potentiated the effect of certain immunotherapies. Yeast-derived particulate β-glucan induces trained innate immunity and successfully reduces murine PC tumor burden. This study tests the hypothesis that IRE may augment β-glucan-induced trained immunity in the treatment of PC. β-Glucan-trained pancreatic myeloid cells were evaluated ex vivo for trained responses and anti-tumor function after exposure to ablated and un-ablated tumor conditioned media. β-Glucan and …

Mechanism And Kinetics Of Photocatalytic Partial Oxidation Of Methane On Single Site Mox Reaction Centers., Clint Evrard

Electronic Theses and Dissertations

Single-site transition-metal doped photocatalysts are a class of materials in which small transition-metal oxide clusters are embedded onto the surface of zeolites, graphene, and bulk semiconductors. Experimental findings demonstrate that VO4, CrO4, NbO4, and WO4 clusters embedded on an MCM- 41 mesoporous amorphous SiO2 are effective photocatalysts for oxidative reactions. The selective direct partial oxidation of methane (POM) to form methanol is essential for efficiently utilizing natural gas. Photocatalytic methane oxidation has advantages over traditional thermal catalysis as it can be deployed at small-scale facilities to reduce methane release into the atmosphere due to flaring potentially. Our work has aimed …

The Effects Of Variations Of Victim Impact Statements On Juror Bias, Emily Sutton

Electronic Theses and Dissertations

Victim impact statements (VIS) are federally protected statements describing the physical, emotional, and financial impact of a crime on a victim. States can decide the content and timing of the VIS, resulting in much variation. Previous research has found an effect of these variations on mock juror bias in capital trials. The current study examined if variations such as changing the strength of emotion, crime type, and including sentencing recommendation within a VIS affects the judgements of mock jurors. The results showed the sexual assault VIS produced higher guilt ratings and longer sentences. Furthermore, the inclusion of a high sentencing …

Exploring The Lived Experiences Of Women Superintendents In Texas, Louisiana, And Mississippi, Lakeyshure Washington-Marzell

Electronic Theses and Dissertations

Abstract

A qualitative phenomenological study examined the challenges and barriers women superintendents encountered in their quest for and service as superintendents in Louisiana, Mississippi, and Texas. Women make up most teaching positions today, but men dominate the superintendent’s office. A correlation should exist between the number of women teachers and the number of women leaders. However, women account for less than one-quarter of superintendents in the United States, while men occupy most positions. A qualitative research design was employed to gain a deeper understanding of the problem. After gathering information from research participants, I performed an interpretative phenomenological analysis to …

Reference Frames In Human Sensory, Motor, And Cognitive Processing, Dongcheng He

Electronic Theses and Dissertations

Reference-frames, or coordinate systems, are used to express properties and relationships of objects in the environment. While the use of reference-frames is well understood in physical sciences, how the brain uses reference-frames remains a fundamental question. The goal of this dissertation is to reach a better understanding of reference-frames in human perceptual, motor, and cognitive processing. In the first project, we study reference-frames in perception and develop a model to explain the transition from egocentric (based on the observer) to exocentric (based outside the observer) reference-frames to account for the perception of relative motion. In a second project, we focus …

Small Gtpase Regulated Intracellular Protein Trafficking In Endothelium, Caitlin Francis

Electronic Theses and Dissertations

Intracellular protein trafficking is the movement of membrane-bound organelles to and from requisite locations within the cell. Small GTPases are a critical component to the spatiotemporal accuracy of intracellular trafficking pathways as they determine the specificity and direction of organelle transport. There exists over 150 small GTPases categorized into 5 sub-families and are employed across all cell types. Despite their universal expression and relevance to cellular function, small GTPases remain incompletely understood across tissue types. In various instances, the trafficking pathway of a particular Rab in one cell type may belong to a completely disparate pathway in another cell type. …
