From Case Study As Symptom To Case Study As Sinthome: Engaging Lacan And Irigaray On "Thinking In Cases" As Psychoanalytic Pedagogy, Erica Freeman

Electronic Theses and Dissertations

This dissertation accomplishes two goals. First, this dissertation articulates a Lacanian account of the epistemological and historical presuppositions of the psychoanalytic case study genre, while engaging reflexively with extant Foucauldian scholarship on this genre as well as feminist psychoanalyst Luce Irigaray’s criticisms of Lacan. Irigaray’s critique is engaged in order to tarry with its implications for a Lacanian approach to the psychoanalytic case study genre. Second, this dissertation critically examines the significance of Lacan’s (re)reading, in Seminar V, of Joan Riviere’s (1929) “Womanliness as Masquerade” in the midst of his oral teachings on the psychoanalytic concepts of castration and …

Afrosofia: Knowledge And Methode Chez Cheikh Anta Diop, Francois Kodena

Electronic Theses and Dissertations

Thinkers generally treat the concept of “philosophy” as a transparent term, defining it as the love of wisdom. However, a quick look at etymological dictionaries and Greek philosophers like Plato or Aristotle leads us nowhere. In other words, we are faced with a semantic conundrum. The verdict is discomforting: “philosophy” is not a Greek concept, and its etymology remains unknown.

This dissertation attempts to decipher that mystery. It leads us to the Afrikan terrain under the guidance of Cheikh Anta Diop and the Beti Mvett through a direct trans-disciplinarian (cultural, monogenetic, historical, linguistic, etc.) Afrosofian methodology.

Ultimately, the Beti So …

Listening To The Voices Of International Undergraduates Regarding Their Perceptions Of Engagement And Their Strategies To Achieve Academic Success, Gulcan Tokluoglu

Electronic Theses and Dissertations

While international students greatly influence globalization with their diverse cultural backgrounds, they often encounter issues when adapting to a new academic, social, and cultural setting. The goal of this research question was twofold in nature in that it sought to not only explore the adjustment experiences of participants but also be able to see what resources and practices were found helpful and needed to be expanded upon in order to provide ways of redressing inequitable practices and contributing to pedagogical change to promote engagement and success of international undergraduate students. A thorough analysis of in-depth interviews considered both upstream and …

A Bioethical Paradigm For Enhanced, Post Or Transhumans In Medicine And Biological Research, Roderick Williams

Electronic Theses and Dissertations

In this dissertation the question addressed is the ethical protocol that should be used when enhanced, post or transhumans present themselves as patients to hospitals, or as subjects for scientific research. With the advent of the birth of four children who were genetically engineered in China to be resistant to HIV, I contend that transhumans are already here, and the prevailing Western paradigm of principlism, while good, is not adequate to the task. I explore the basic religious argument that can be used against or in favor of what I call human-directed human evolution. I show how the fears of …

Effects Of Hands-On Experiences On Student Achievement, Interest, And Attitude In Chemistry, Donna Gretchenn Adkins

Electronic Theses and Dissertations

This study examined the effect of hands-on experiences on student achievement, interest, and attitude in chemistry. The researcher gathered data from 82 students enrolled in an East Texas high school chemistry course for the 2019-2020 school year. Historical data from five-unit tests were used to assess differences in mean achievement scores between test items aligned with hands-on laboratory experiences and test items aligned with computer-simulated experiences. An independent t-test and a paired t-test were used to statistically evaluate the data. The independent t-test showed no statistically significant difference. However, the paired t-test did indicate a statistically significant difference. To assess …

Bacteria Analysis By Using A Supervised Machine Learning Algorithm Based On Droplet Microfluidics, Yulder Daniel Angarita

Electronic Theses and Dissertations

Sepsis is a major medical problem and massive resources have been invested in developing and evaluating alternative treatments. Statistics indicate that sepsis causes between one third and one half of all hospital deaths in the United States. Sepsis has a high impact on health care in the US, with direct sepsis costs in 2009 exceeding $15.4 billion. A research study found that a 1-hour delay in appropriate antimicrobial care resulted in a 7% - 10% rise in mortality. Several professional societies seek to reduce sepsis mortality by targeting the timely use of diagnostic tests and antimicrobial therapy. The diagnostic instruments …

Isolation, Structure Elucidation, And Synthesis Of Natural Products From Marine Cyanobacteria, Keren Solomon

Electronic Theses and Dissertations

This thesis describes the isolation, structure elucidation, and synthesis of natural products from marine cyanobacteria. A crude extract from a cyanobacterium collected in Curacao showed selective affinity for the dopamine D₅ receptor in a screen against a panel of CNS receptors. Due to the high similarity of the D₅ and D₁ receptor, to date there are no known ligands that differentiate them. Attempts to purify the compound responsible for this affinity led to the isolation of the known compound caylobolide A. A second extract from a cyanobacterium collected in Panama underwent bioassay-guided fractionation and yielded the novel …

The Influence Of Environmental Variables On The Height Growth Of Loblolly Pine (Pinus Taeda) In The Western Gulf, Osakpamwan Edo-Iyasere

Electronic Theses and Dissertations

Understanding the effects of environmental factors on stand growth is important in optimizing forest management plans. This study investigated the effects of soil and climate factors on the height growth (site index) of loblolly pine (Pinus Taeda L.) using data collected from permanent plots established in intensively-managed plantations across East Texas and Western Louisiana. The Chapman-Richards model was selected as the base model to describe the height-age relationships and important soil and climate variables were incorporated into the models as model parameter coefficient adjustors. Our results showed that the most important factors for predicting site index were nitrogen …

(Pseudo)Phase Tuning In The Service Of Synthesis: Technologies For Sustainable Catalysis., Justin Douglas Smith

Electronic Theses and Dissertations

Strategies for manipulation of chemical phases were explored with emphasis on synthetic chemistry applications. Some strategies are fairly divergent from their origin, but all ultimately began from investigations of micellar media. Accordingly, Chapter 1 reviews the historical development of micellar catalytic processes. Chapters 2 and 3 detail development of synthetic methods in micellar solutions of designer surfactant PS-750-M. PS-750-M was designed to create benign micellar solutions which effectively mimic toxic organic solvents; it contains a proline-based linker between its hydrophobic and hydrophilic regions which imparts increased polarity to the micellar core. Chapter 2 details an interfacial nucleophilic substitution of perfluoroarenes …

Nonlinear Control And Observation Of Full-Variable Speed Wind Turbine Systems., Nicholas Hawkins

Electronic Theses and Dissertations

With increasing concern for the environmental effects of power generation from fossil fuels, wind energy is a competitive source for electrical power with higher efficiency than other clean sources. However, the nature of this power source makes controlling wind turbines difficult. The variability of wind as a source either requires highly accurate measurement equipment or sophisticated mathematical alternatives. In addition to the unknown quantities of the weather itself, the efficiency of power capture at the turbine blades is highly nonlinear in nature and difficult to ascertain. The ability of either determine these troublesome quantities, or control the system despite ignorance …

Model-Based Control Methods To Improve The Power Qualify Of Grid-Connected Single-Phase Inverters., Moath Alqatamin

Electronic Theses and Dissertations

Power electronic converters are commonly used for interfacing distributing generation sources (DGs) to the electrical power system networks. This is necessary because these DGs usually have different output characteristics and cannot be connected directly to the local load and/or the grid. The power electronic front-end converter is an inverter whose dc link is fed by an ac/dc converter or by a dc/dc converter, according to the DG source type. The commercial front-end inverters are designed to operate either in grid-connected (GC) mode or in stand-alone (SA) mode. In the SA mode, the inverter is connected to local load, but in …

Mathematical Models And Analysis For Demand Side Management In Residential Electricity Distribution Networks., Arnab Roy

Electronic Theses and Dissertations

Development of smart grids along with communication technologies have led to the increased attention and adoption of demand side management (DSM) in the residential sector. Among various DSM schemes, demand response (DR) is a market- based mechanism to shave peak electricity consumption at the system level. In the past decade, the academia has seen a growing literature studying load management methodologies for residential consumers. A typical demand response program has three important facets: the energy cost, comfort of the consumers and overall system efficiency. In this dissertation, we investigate and develop models for effective load control to minimize energy cost …

Evaluation Of Groundwater Sodium And Sodium Uptake In Taxodium And Its Hybrids On Galveston Island, Texas, Daniel Morgan

Electronic Theses and Dissertations

In September 2008, Hurricane Ike swept through the Gulf of Mexico striking the Gulf Coast, claiming hundreds of lives and causing billions of dollars in damage. The hurricane left behind elevated sea salt concentrations in the soil and groundwater, preventing the unaided return of live oaks and other species to the island. To determine effective ways to ameliorate the elevated Na⁺ concentrations in the soil, eight treatments were applied to the soil and combinations of three species of plants, live oak (Quercus virginiana), hybrid bald cypress (Taxodium ‘T406’), and yellow hibiscus (Hibiscus hamabo …

Causal Comparative Study: The Effect Of School Scheduling And Academic Outcomes Of Economically Disadvantaged Students, Marcus D. Brannon

Electronic Theses and Dissertations

This study was designed to investigate if a statistical variance exists between traditional and A/B block school scheduling, and the effect on economically disadvantaged student achievement on the English I and Algebra I End-of-Course STAAR state-mandated exam, from 2015-2018. In response to studies illuminating the achievement gap, educational leaders in Texas implemented block scheduling in order to improve student outcomes among high school students. However, to date, published research studies yield mixed results of the effectiveness block scheduling has made on student achievement. The findings are expected to help to fill the gap in published literature, which focuses on the …

Maya Bone Tool Technologies At Ucanal, Guatemala, Jacob Harris

Electronic Theses and Dissertations

A key part of understanding Maya bone tool production is studying the rare assemblages containing bone tools and bone tool debitage. The Late Classic J-2 assemblage is a distinct composition of lithic, charcoal, human and animal bone at the site of Ucanal, Guatemala. The number of sites with high concentrations of fauna remains are well, and sites with high concentrations of worked bone is even rarer. This thesis is an analysis of the worked and unworked faunal elements excavated in 2019 from Operation 1B of the J-2 assemblage. The primary purpose of this thesis is to further understand Maya bone …

Decompositions Of The Complete Mixed Graph By Mixed Stars, Chance Culver

Electronic Theses and Dissertations

In the study of mixed graphs, a common question is: What are the necessary and suffcient conditions for the existence of a decomposition of the complete mixed graph into isomorphic copies of a given mixed graph? Since the complete mixed graph has twice as many arcs as edges, then an obvious necessary condition is that the isomorphic copies have twice as many arcs as edges. We will prove necessary and suffcient conditions for the existence of a decomposition of the complete mixed graphs into mixed stars with two edges and four arcs. We also consider some special cases of decompositions …

Jangle Fallacy: Is Grit Distinct From Other Psychological Constructs?, Natasha Godkin

Electronic Theses and Dissertations

This paper assessed the redundancy of the construct of grit (Crede, Tynan, Harms, 2017) compared to other similar constructs using structural equation modeling to remove the effect of measurement error. A series of models regressed grit and its subdomains (passion and perseverance of effort) on self-control, conscientiousness, achievement striving, and resilience. The R-squared values for these models ranged from 0.62 to 0.89. It is concluded that the concept of grit is mostly redundant with other constructs and is therefore an example of a Jangle fallacy (Kelley, 1927). The unique aspect of grit is mostly related to its passion …

Paleoenvironmental Reconstruction Of Quaternary Saltville, Virginia, Using Ostracode Autecology, Austin Gause

Electronic Theses and Dissertations

The Saltville valley in southwestern Virginia is home to Quaternary localities containing paleontological and archaeological remains. Historically the valley has been mined for salt and the small lakes, ponds and springs along the valley floor have a brackish signature. A preliminary report on the site’s ostracode fauna suggested that the site’s water was not always saline. This study analyzed modern and Quaternary ostracodes to understand the valley’s hydrologic and chemical evolution. Sediments contained primarily freshwater species, including the environmentally sensitive Candona crogmaniana. The presence of Pelocypris tuberculatum and a new Fabaeformiscandona species throughout a vertical section spanning the latest Pleistocene …

A Gis-Based Method For Archival And Visualization Of Microstructural Data From Drill Core Samples., Elliott Holmes

Electronic Theses and Dissertations

Core samples obtained from scientific drilling could provide large volumes of direct microstructural and compositional data, but generating results via the traditional treatment of such data is often time-consuming and inefficient. Unifying microstructural data within a spatially referenced Geographic Information System (GIS) environment provides an opportunity to readily locate, visualize, correlate, and explore the available microstructural data. Using 26 core billet samples from the San Andreas Fault Observatory at Depth (SAFOD), this study developed procedures for: 1. A GIS-based approach for spatially referenced visualization and storage of microstructural data from drill core billet samples; and 2. Producing 3D models of …

Utilizing The Public On Public Lands: The Application Of Community Science To Monitor And Model Erosion In National Forests, Jacob L. Hansen

Electronic Theses and Dissertations

Unpaved forest roads are adversely affecting coldwater streams through excessive erosion and the subsequent sedimentation of adjacent waterways. To help identify areas of concern, Trout Unlimited (TU) in the Southern Appalachian region developed a Community Science initiative to gather data on sediment sources and stream-road crossings. Volunteers were recruited and trained to monitor road and trail conditions and collect and submit data using a Survey123 application on their cell phones. Analysis of the contributed data reveals statistical connections between drainage type and both erosion level and stream sedimentation. The contributed data were also included as a calibration for the lite …

A Structural Study Of Correlated Materials: Incipient Mott Insulators And Low-Dimensional Systesm., Alaa Alfailakawi

Electronic Theses and Dissertations

Current theories of high-temperature superconductivity suggest that electrons must organize into Cooper pairs in order for a material to exhibit a superconducting phase. Electrons in insulators experience significant repulsive interactions that tend to keep electrons localized at atomic positions. In contrast, electrons in metals are delocalized, interact weakly, and are free to conduct electricity. Therefore, the formation of Cooper pairs should have different mechanisms for metals compared to insulators. This contrast raises the debate about the origin of high-temperature superconductivity in iron-based material, whether it depends on the strong or weak coupling. Many iron-based materials are metallic in the normal …

Convolution Inequalities And Applications To Partial Differential Equations., Matthew Reynolds

Electronic Theses and Dissertations

In this dissertation we develop methods for obtaining the existence of mild solutions to certain partial differential equations with initial data in weighted L p spaces and apply them to some examples as well as improve the solutions to some known PDEs studied extensively in the literature. We begin by obtaining a version of a Stein-Weiss integral inequality which we will use to obtain general convolution inequalities in weighted L p spaces using the techniques of interpolation. We will then use these convolution inequalities to make estimates on PDEs that will help us obtain mild solutions as fixed points of …

Linear Methods For Regression With Small Sample Sizes Relative To The Number Of Variables., Rajesh Sikder

Electronic Theses and Dissertations

In data sets where there are a small number of observations but a large number of variables observed for each observation, ordinary least squares estimation cannot be used for regression models. There are many alternative including stepwise regression, penalized methods such as ridge regression and the LASSO, and methods based on derived inputs such as principal components regression and partial least squares regression. In this thesis, these five methods are described. K-fold cross validation is also discussed as a way for determining regularization parameters for each method. The performance of these methods in estimation and prediction is also examined through …

A Comprehensive Study Of The Short-Term Variability Of The Migrating Diurnal Tide In The Mesosphere And Lower Thermosphere., Lokupatabendige Ashan Shivantha Vitharana

Electronic Theses and Dissertations

Our ability to understand and predict space weather has become vital due to its significant societal impacts on communication, transportation, and national defense. One of the most exciting discoveries in the last decade has been the realization that tropospheric weather can strongly influence space weather. It is now recognized that the atmospheric waves (gravity waves, atmospheric tides, and planetary waves) play a key role in coupling the lower and upper atmosphere. The focus of this dissertation is to study atmospheric tides. While the climatology of tides has been extensively studied, little is known about the tidal weather (tidal variability
