Electrical Characterization Of Phytoplankton Suspensions Using Impedance Spectroscopy., Margaret R Jett

Electronic Theses and Dissertations

Phytoplankton are closely monitored because of their important environmental role, and the impacts they have on their local ecosystems. Some phytoplankton respond to stress by producing lipids, which can be harvested for biofuels and other chemicals. Microfluidic devices have been important in improving the portability and throughput of phytoplankton characterization methods, increasing their potential for in situ use. This study utilized a small sample of phytoplankton suspended in a stagnant medium and measured the impedance response using a lab-on-chip and impedance analyzer. The individual cell characteristics were derived from the impedance response of the group. The goal was to characterize …

Development And Evaluation Of A Body Weight Support Treadmill For Use With Locomotor Training On Pediatric Spinal Cord Injury Patients., Winston T Rauch

Electronic Theses and Dissertations

The consequences of spinal cord injury (SCI) are devastating regardless of the age of a patient. When the injury occurs in children five years old or younger, however, the impact is magnified due to the inevitable development of scoliosis (96%) and hip dysplasia (57%) (Schottler et al., 2012). To reduce occurrence of these complications and improve the quality of life for these patients, specialized activity-based therapies such as locomotor training (LT) are being increasingly used to improve overall trunk control and muscle activity in the lower extremities (Harkema et al., 2012; Howland et al., 2014). The aim of this therapy …

Spatial Analyses Of Gray Fossil Site Vertebrate Remains: Implications For Depositional Setting And Site Formation Processes, David Carney

Electronic Theses and Dissertations

This project uses exploratory 3D geospatial analyses to assess the taphonomy of the Gray Fossil Site (GFS). During the Pliocene, the GFS was a forested, inundated sinkhole that accumulated biological materials between 4.9-4.5 mya. This deposit contains fossils exhibiting different preservation modes: from low energy lacustrine settings to high energy colluvial deposits. All macro-paleontological materials have been mapped in situ using survey-grade instrumentation. Vertebrate skeletal material from the site is well-preserved, but the degree of skeletal articulation varies spatially within the deposit. This analysis uses geographic information systems (GIS) to analyze the distribution of mapped specimens at different spatial scales. …

Tennessee's Voluntary Prekindergarten (Vpk) Program And Kindergarten Achievement, Kindetta L. Thompson

Electronic Theses and Dissertations

The purpose of this quantitative study was to investigate whether there is a relationship between Tennessee's Voluntary Prekindergarten (VPK) program and kindergarten achievement. I compared the academic growth of who attended a VPK program to students in Title 1 schools who did not attend a VPK program. Kindergarten gives the first easyCBM assessment in the second semester of school. I compared the easyCBM scores of the students who attended a VPK program to the ones who did not attend a VPK program. This could reveal if attending the VPK program is related to the students’ academic growth and the amount …

Corporate Social Advocacy On The Blm Movement: A Content Analysis Of Corporate Responses Via Instagram, Oromidayo Racheal Tunji-Ajayi

Electronic Theses and Dissertations

Black Lives Matter (BLM) has been a concern in the US since 2013, thereby becoming an increasing interest. Several US corporations’ attention has been drawn to BLM due to its radical strategy on social media to facilitate engagements. Research shows that a company's engagement in activism by taking a stance on socio-political issues often records growth. Also, scholars have focused on corporate responses to BLM through the lenses of the implications or intentions of the brand’s engagement. This study, however, analyzes 236 corporate Instagram BLM posts through the lenses of the attributes of their responses. It is assumed that brand …

The Impact Of Natural Playscapes On Toddler Play, Laura J. Pearce

Electronic Theses and Dissertations

A distinct lack of data related to the impact of natural environments on children birth to age 3 was identified by a thematic review of the existing literature. With this in mind, the researcher designed a limited scope quantitative study to explore the potential for extending the existing body of research to include this younger age. The study used a time sampling method to code behaviors that occurred in videos collected of children from 12 to 35 month who were playing on the playground at their childcare facility. The playscapes were classified as naturalistic or manufactured. The data was then …

Isotopic Analysis And Mobility Mapping Of Mammuthus Columbi From The Mammoth Site In South Dakota, Matthew Harrington

Electronic Theses and Dissertations

The Mammoth Site in Hot Springs, South Dakota preserves a unique death assemblage of sub-adult and adult male Columbian mammoths (Mammuthus columbi). Extensive work on the site has led to a detailed understanding of the taphonomy of the assemblage; yet the life histories and ecology of these mammoths remain relatively unknown. Tooth enamel from four Mammoth Site mammoth individuals were bulk sampled with one of the individuals (MSL 742) also serially micro-sampled for 𝛿¹³C, 𝛿¹⁸O, and ⁸⁷Sr/⁸⁶Sr. Isotopic results indicate that MSL 742 remained within the southern and western Black Hills …

Neuroinflammation, Peripheral Inflammation And Gut Microbiome Profiles In Male Mice From Two Proposed Mouse Models Of Social Behavior Deficits, Sarah Parkinson

Electronic Theses and Dissertations

Autism spectrum disorder (ASD) is a neurodevelopmental disorder marked by social deficits and repetitive actions. A communication pathway exists between the brain and gut called the gut-brain axis. It is thought that gut bacteria can secrete signaling molecules, triggering inflammation across the body. These studies attempt to determine if markers are expressed in two mouse models of ASD behaviors, BTBR and a valproic acid model. Immunohistochemistry of ionized calcium binding adaptor molecule 1 from male mouse brain tissue showed no microglial activation in any group. Cytokine analysis did exhibit an increase in interleukin 1 (IL-1) in male adult mice only. …

Endothelial Heat Shock Protein A12b And Yes-Associated Protein Cooperatively Promote Angiogenesis Following Myocardial Infarction, Min Fan

Electronic Theses and Dissertations

Heart failure after myocardial infarction (MI) remains the leading cause of mortality among all cardiovascular diseases globally. Angiogenesis plays a critical role in cardiac functional recovery after MI. Heat shock protein A12B (HSPA12B) is predominately expressed in endothelial cells and required for angiogenesis. Yes-associated protein (YAP) has been reported to promote tumor angiogenesis.

In the present study, we investigated the cooperative role of HSPA12B and YAP in angiogenesis following myocardial ischemic injury. Endothelial specific deficiency of HSPA12B (eHspa12b^-/-) or YAP (eYap^-/-) impairs angiogenesis and exacerbates cardiac dysfunction after MI, when compared with wild type …

Food-Web And Functional Trait Community Structure Of Predator Assemblages In Pine Forests Under Different Management Regimes, Connor Adams

Electronic Theses and Dissertations

Anthropogenic activities can alter natural disturbance regimes in ecosystems, and thereby affect the structure and function of biological diversity. As many of the world’s ecosystems are degraded beyond natural recovery, well-defined restoration goals are necessary to maintain the ecological processes that provide valuable ecosystem services. Utilizing taxonomic, functional, and food-web approaches, I investigated the impacts of forest management practices in structuring predator communities in two pine forest systems of eastern Texas. The results of this study indicate that the increased frequency of forest management practices such as prescribed fires and thinning operations encourages predator diversity while increasing functional and trophic …

Machine Learning Applied To Colloidal Properties Of Perfluorocarbon Nanoemulsions For Imaging In Ards/Ali, Marco Hosfeld

Electronic Theses and Dissertations

Acute Respiratory distress Syndrome (ARDS) and Acute Lung Injury (ALI) are inflammatory lung pathologies consisting of non-hydrostatic pulmonary edema leading to hypoxia and impaired gas exchange in the lungs. ARDS/ALI is both difficult to study and treat as it is not in itself a specific pathology but rather a syndrome consisting of many pathologies that vary case by case. It is, however, consistently characterized by an explosive acute inflammatory response in the lung parenchyma leading to hypoxia. Although time has seen to an increase in the understanding of ARDS/ALI, the mortality rate remains in the range of 30-50%. For these …

Unicorns Are Not Real And Neither Are You: Peter S. Beagle's Postmodern Fairy Tale, Athena Hayes

Electronic Theses and Dissertations

Although considered by many readers to be a “cult classic,” Peter S. Beagle’s 1968 novel The Last Unicorn has been unrepresented in literary scholarship. Many fantasy critics in the past have dismissed the work as lacking a sense of reality through its mixing of modern language with a medieval, fantasy setting. However, the novel’s purposeful muddling of reality raises questions of ontology and the nature of storytelling/world-projection. The objective of this study is to not only to act as a sort of apologetic for The Last Unicorn, but also read the novel in the context of fairy tale/mythic studies …

The Rhetoric Of Parody And Persona: The Rhetorical Construction Of Donald Trump Through Parody In The 2016 Election, James Lyle

Electronic Theses and Dissertations

The intent of this dissertation is to explore the rhetorical nature of parody in the context of the American electoral process. This work draws on existing research in the field to show how humor is an important method for engaging the public sphere. This project develops the rhetorical nature of humor, works through existing research on conceptualizations of humor and its importance for societal dialogue, and then addresses the specific contributions to the study of parody offered by Mikhail Bakhtin and Kenneth Burke to demonstrate the potential for parody to act as a form of rhetorical illumination of existing rhetorical …

You Are Not Welcome Here: Sloterdijk’S Posthumanism And The Rhetoric Of Hostile Urban Architecture And Design, Brandon William Aungst

Electronic Theses and Dissertations

This dissertation brings together three scholarship areas: rhetorical theory and analysis, hostile urban architecture and design, and Sloterdijk’s version of posthumanism. I synthesize these complementary areas to address the following questions: How do architecture and design contribute to the rhetorical meaning-making of being human and facilitate the communication of that meaning to others? How do different types of architecture and design produce the material contexts for conceptualizing what humanness means and contribute to the development of fore-structures for interpreting and communicating that humanness (e.g., hostile architecture and barbed wire)? How can we conceptualize various types of architecture and design, or …

Cultivating Eliot's Historical Sense: Eliotic Time And The Waste Land's Response To Alienation, Thomas Ball

Electronic Theses and Dissertations

In this dissertation, I argue that T.S. Eliot’s The Waste Land marshals his account of historical sense as a response to the problem of alienation in modernity. Eliot’s historical sense depends upon an awareness of the endurance of the past, demanding a reorientation to the structure of temporality. I interrogate the temporal ramifications of Eliot’s account, arguing that it resonates with Henri Bergson’s durational theory of time. I ultimately investigate Eliot’s relationship to Bergson, suggesting that Eliot intervenes in the Bergsonian framework by establishing duration as a cultural, rather than individual or ontological, reality.

An Interpretive Phenomenological Analysis Of Psychotherapists' Experiences Of Vulnerability, Kay Yu Yuan Chai

Electronic Theses and Dissertations

In the service of forging a deep authentic connection that has the power to heal and transform, psychotherapists create and hold space for their patients to show themselves in a deeply vulnerable manner so that they can be known and accepted as they are. At the same time, psychotherapists are also flawed and wounded mortal beings who cannot help but bring their own woundedness, personalities, and limitations into the space, and must negotiate the delicate balance between restraint and expressiveness of their vulnerability. This study is a phenomenological inquiry into how psychotherapists experience their vulnerability given the demands of their …

Civil Religion And The Second Amendment, Shivaun Corry

Electronic Theses and Dissertations

The American approach to legal hermeneutics emerged from the covenant theology of the Puritans. American civil religion understands the Constitution to be based in natural laws: a secularized conception of God-given rights. To change the text would collapse the epistemological framework of the nation. When a nation sees its constitution as a sacred text, then the answer to contemporary problems cannot be to change that text; rather, it must be to return to the text with an even more fundamentalist hermeneutic. Both gun rights advocate Charlton Heston, and gun control advocate Barak Obama, argued their cases using a fundamentalist hermeneutic, …

Rhetoric And Philosophy Of Communication In Jorge Luis Borges' Metaphysical Obsession With Time, Aurora M. Pinto

Electronic Theses and Dissertations

This project begins with the assumption that through storytelling we humans make sense of the world around us. Language and communication are powerful in defining who we are and allowing individuals to “become a self” (Taylor The Language 318). Drawing from Schrag, I argue that rhetoric is inextricably linked to discourse but is also situated beyond its classical persuasive function. Rhetoric evokes a response from the other, based on reflection and deliberation. Since that other might be a reader of texts of fiction, there is a rhetorical connection to interpretation that situates literature as an exemplar of communicative engagement.

Diagnosis Of Melanoma Disease State From Patient Blood Samples Using Photoacoustic Flow Cytometry, Jacob Salvatore

Electronic Theses and Dissertations

Approximately 1 in 50 Americans develop melanoma in their lifetime. Early detection of melanoma is pivotal to the survival of the patient, with a 99% survival rate for 5 or more years after an early diagnosis. Metastasis, or the spread of cancer, increases the chances of cancerous growth in other parts of the body. In this study, we propose the use of photoacoustic flow cytometry as a diagnostic of patient disease state, by closely monitoring the amount of circulating melanoma cells (CMCs) in a patient’s blood before and after chemotherapy treatments. Using this patient data, we were able to make …

Get Ready For Future Education: A Phenomenological Study On Artificial Intelligence, Son T. H. Pham

Electronic Theses and Dissertations

Artificial intelligence (A.I.) brings new opportunities for social construction. This phenomenological research attempted to analyze the phenomenon of artificial intelligence in education, grounding in American philosophy, with a review of the history of A.I. in education, its promise, and possible futures. The primary purpose of the study was to share voices and lived experiences of educators, philosophers, industrialists and politicians toward the coming high-tech society. Fundamental to this philosophical inquiry was Heideggerian interpretive phenomenology. The findings from eight intellectuals participating in this study elucidated five themes of the investigated phenomenon. Together these empirical indicators, and an outline of philosophy of …

Effect Of Single Vs Accumulated Bouts Of Exercise On Body Composition, Fitness, And Resting Metabolic Rate, Alexander Alvara

Electronic Theses and Dissertations

Obesity and physical inactivity are two factors that have been shown to be correlated with cardiovascular disease (CVD) and diabetes. As people have increasingly busier schedules, they have less time to commit to exercise. Accumulating exercise in small bouts is a schedule-friendly alternative to longer continuous bouts of exercise and may protect against CVD and diabetes. Therefore, the purpose of this study was to examine the effects of accumulated exercise compared to continuous exercise on body composition, fitness, and resting metabolic rate. Nine healthy male (n=4) and female (n = 5) volunteers were randomized into either an accumulated intervention group …

Animated By The Spirit: An Ecclesiology For Assessing Charism-Centered Mission In Higher Education, Michelle Nicole Blohm

Electronic Theses and Dissertations

A “charism-centered” institutional mission is a mission that is believed to be instantiated and guided by the working of the Holy Spirit. Countless Catholic higher education institutions claim to have missions rooted in one or more charisms. However, institutional assessment processes tailored to charism-centered missions have remained in their infancy due to the lack of a theological grounding for institutional charism and its assessment. This work uses Yves Congar’s pneumatological ecclesiology to establish a theological framework for interpreting charism as respecting and enhancing stakeholder diversity and uses Louis-Marie Chauvet’s ecclesiology of symbol to pioneer a model for institutionally assessing charism-centered …

Meeting Myself As A Scholarly Practitioner: A Self-Study Exploring The Process Of Integrating Instructional Technology Into Introductory Theater Courses, Ramona Broomer

Electronic Theses and Dissertations

Abstract

A growing number of faculty in higher education are using technology applications in their teaching practices. However, a gap in the literature exists related to instructional technology integration in liberal arts courses. This gap also exists in theater education, where I have spent the last 20 years of my professional life. This self-study analyzed my knowledge and practice of using instructional technology in theater education. Using technological and pedagogical content knowledge (TPACK) as a theoretical framework, I examined my teaching of introductory theater courses in face-to-face and online formats. As part of the inquiry process, I collected and analyzed …

Communication As Change: Marshall Mcluhan And A Transformation Model Of Communication, Lane Grafton

Electronic Theses and Dissertations

The work synthesizes Marshall McLuhan’s transformation model of communication with a trivium-based educational model and challenges the modern-day position of unreflective mediated communication. McLuhan’s transformation model demonstrates that communication is more than the transfer of content; rather, it is a transformation of perception. This work broadens the analysis and suggests that figure and ground relationships are integral to seeing the whole of media transformations. Through figure and ground relationships, communication unfolds as a study of perceptual change. The work explores perceptual change within the context of McLuhan’s conversion to the Catholic Church and underscores the importance of a unified mind …

An Ethical Foundation For Genetic Therapy And Gene Editing (Crispr), Nikolija Lukich

Electronic Theses and Dissertations

There are many steps involved in the process of introducing CRISPR-Cas9 into the current health care system. This dissertation provides an ethical foundation for the uses of CRISPR-Cas9 genetic therapies and editing techniques, which organizations can utilize when implementing these new technologies. Multiple components must be examined, including the practical application of the concept of autonomy, which benefits from the inclusion of personalism and care ethics as it aims to provide a more effective method upholding the right to independent decision-making. In addition to individual considerations, population-based decisions and public health tools are explored, connecting the human right to health …

But Also Full Of Seeds For A Future That Could Have Turned Out Differently., Megan Marie Bickel

Electronic Theses and Dissertations

This thesis examines the relationship between "illusion," "allusion," and their relationship to contemporary images which announce, shield, or reference information. Beginning by discussing Casualist and Post-Digital Painting discourse, two styles I work within, we see connecting tissue in announcing and shielding of meaning. We look at the meaning of marks, and in the parallel exhibition, marks that utilize camouflage strategies appear as a metaphor for illuding to information which appears as conveying depth when there is none, and using paintings' symbols in objects that are not paintings. The work 'alludes' to what the viewer has seen before and relies on …

Sex-Based Differences In Microbiota Composition And Metabolomic Profiles Associated With Altered Macrophage Function And Protection From Lupus In Bwf1 Mice., James William Harder

Electronic Theses and Dissertations

Systemic lupus erythematosus (SLE) is a complex and an insidious disease that is still not completely understood, and has very few treatment options. Those that are available are ineffective and/or have serious side effects. Both genetic and environmental factors contribute to the susceptibility and resistance to SLE, and understanding the environmental factors underlying this disease could lead to more effective prevention and/or treatment strategies. Like most autoimmune diseases, SLE is much more prevalent in females than males. While there are numerous factors that contribute to this lupus susceptibility, there is increasing evidence that the microbiota can strongly influence lupus progression, …

In A Victorian Fog: Constructing Identities In Female Gothic Novels., Hayley Salo

Electronic Theses and Dissertations

Drawing on feminist criticism and postcolonial theory, this study analyzes conversations about female identity within and around Victorian female gothic novels and how they contribute to the genre’s appeal to modern readers. In particular, it is a case study of how the discourse develops through Mary Shelley’s Frankenstein (1818), Emily Brontë’s Wuthering Heights (1847), and Charlotte Brontë’s Jane Eyre (1847). Each novel presents the challenges women face when their sense of self is based on the expectations of others, and Wuthering Heights and Jane Eyre further explore the potential for women to create their own, unique identity while still remaining …

Rna G-Quadruplex Structures: Functions In Noncoding Rnas And Disease, Emily Benner

Electronic Theses and Dissertations

Paraspeckles are a relatively newly identified subnuclear body whose function is still largely unknown. They are membraneless organelles found within mammalian nuclei originally identified as being comprised of different paraspeckle proteins (PSPs), and later proven to also contain RNA. This study investigates the long non-coding RNA nuclear enriched abundant transcript 1 (NEAT1), which has been found to be indispensable in the formation of paraspeckles, with each containing up to 50 NEAT1 molecules. NEAT1 has two isoforms, the shorter NEAT1_1, and the longer NEAT1_2. The focus of this work will be on the NEAT1_2, which acts as a scaffold in the …
