Show moreThis thesis is composed of a collection of essays on the themes of motherhood, loss, and grief. Through the use of innovative form, these essays thread together personal narratives and research to find language for complicated manifestations of loss. These essays experiment with structure and form to grapple with the illusive nature of memory, loss, and healing. The essays in this collection attempt to find healing and meaning through language and meditation. This collection is also an attempt at categorizing grief when normative societal ideas are challenged by complicated loss. This work serves as a call to action that there should be better recognition of uncommonly recognized manifestations of grief.

In this thesis, feasibility of a concept for launch and recovery of the Remus AUV from WAM-V USV is investigated. A modular recovery system which can be added to the WAM-V payload tray was designed, and based on a review of previous literature a CONOPS was developed for the launch and recovery process. The first phase of the CONOPS, which pertains to the position of the REMUS initially on the free surface prior to sling engagement is simulated using ANSYS AQWA. Preprocessing for the...
Show moreIn this thesis, feasibility of a concept for launch and recovery of the Remus AUV from WAM-V USV is investigated. A modular recovery system which can be added to the WAM-V payload tray was designed, and based on a review of previous literature a CONOPS was developed for the launch and recovery process. The first phase of the CONOPS, which pertains to the position of the REMUS initially on the free surface prior to sling engagement is simulated using ANSYS AQWA. Preprocessing for the simulation involved simplification of the model in ANSYS SpaceClaim to achieve a proper mesh as well as theoretical calculations of the input parameters for wave environment and point masses etc. The simulation was evaluated by taking into consideration two wave environment scenarios: beam sea’s (-90 degrees) and head seas (0 degrees). The wave environment was based on a linear frequency range for the waves which considered wavelengths that correspond to half and double the length of the WAM-V 16’. The significance of the simulation is characterized through identifying the ideal direction and wave frequency range for recovery based on the RAOs of the two vehicles.

Show moreThe current study examined how viewing an event from different perspectives (eye-level and elevated) at both encoding and retrieval changes the recognition of that event. Specifically, participants were shown various manipulations to the scenarios that they witnessed at encoding. The primary focus of the study was the participants’ ability to identify old scenarios along with scenarios that had been manipulated through differences in character clothing, object placement, or temporal order of events, while still resembling the old scenario in every other way. No support was found to support the prediction that perspective at either encoding or retrieval had an effect on recognition of the scenario or the different manipulation types. An exploratory analysis revealed a trend towards significance for perspective at encoding. An eye-level perspective at encoding was more likely to result in a higher rejection rate for temporal manipulations.

Show moreProton Therapy, an effective cancer treatment, poses unintended consequences for patients and personnel due to secondary neutron production. This study investigates neutron attenuation in shielding materials like concrete using Monte Carlo (MC) simulations to optimize shielding requirements. Experimental limitations, such as detector sensitivity, energy range response, and spatial resolution, lead to inaccurate evaluations. MC simulations address that by modeling radiation transport and neutron interactions with shielding materials. The TOPAS-MC code simulated secondary neutrons generated by a 226.5 MeV energy proton beam on a 30 cm diameter tissue-equivalent target. The target was placed in a 200 cm spherical concrete shell with a 100 cm inner radius and 2.3 g/cm3 density. Energy deposition and particle fluence were scored in 20 radial points across 18 angular positions, and the mean value per particle was estimated. Neutron fluence to ambient dose equivalent conversion coefficients from ICRU Report No. 95 were used to calculate the total dose equivalent values, which were scaled based on distance and concrete shield thickness.

Show moreTau, a microtubule-associated protein, is involved in more than 20 different tauopathic disorders characterized by aberrant intracellular aggregation of tau in the brain. However, it is still unclear how this highly soluble tau protein aggregates inside the brain. Thus, understanding the mechanistic details of tau aggregation is critical for unraveling the underlying pathology of tauopathies and developing effective strategies to inhibit tau aggregation. Herein, we investigated the aggregation of a novel 20-residue model peptide, tau₂₉₈₋₃₁₇, derived from the key microtubule-binding domain of the full sequence tau. Our study demonstrates that tau₂₉₈₋₃₁₇ highly mimics full-length tau's physical and aggregation properties. The fibrillation of the peptide is strongly dependent on external factors. The presence of polyanionic heparin (Hep) significantly promotes the aggregation of this peptide to form amyloid fibrils. The Hep-induced aggregation is sensitive to the ionic strength of the solution, suggesting an important role of electrostatic interactions in the mechanism of Hep-mediated aggregation. In addition, two positively charged polysaccharides, chitosan (CHT) and its quaternary derivative N-trimethyl chitosan (TMC), effectively inhibit Hep-induced aggregation of tau₂₉₈₋₃₁₇ in a concentration-dependent manner. Attractive electrostatic interactions between the positively charged moieties in CHT/TMC and the negatively charged residues of Hep play a critical role in inhibiting Hep–peptide interactions and suppressing peptide aggregation.

Pile foundations are subjected to vertical loads and significantly higher lateral loads due to wind, seismic effects, ocean waves and currents, and floating ice sheets. Applied vertical load on a pile is resisted by the skin friction and base resistance. The base resistance is provided by the soil layer and skin friction develops at the soil-pile interface.

Show morePile foundations are subjected to vertical loads and significantly higher lateral loads due to wind, seismic effects, ocean waves and currents, and floating ice sheets. Applied vertical load on a pile is resisted by the skin friction and base resistance. The base resistance is provided by the soil layer and skin friction develops at the soil-pile interface. The lateral load on the pile is resisted by the soil-pile interaction effect, which is dependent on the pile and soil parameters. Published literature shows that a properly designed Pile-to-Pile Cap (PTPC) connection will offer significant lateral resistance to the applied loads. The soil-pile system behavior is highly non-linear which requires a detailed study on the soil-structure interaction considering multi-layered soil strata and their properties. This Dissertation is divided into two parts: Evaluation of (A) the behavior and performance of PTPC connections, and (B) the load-displacement responses of a pile embedded in a multi-layered non-linear elastic soil strata subjected to static loads. A comprehensive literature review has been performed to study the factors affecting the PTPC connection performances and the load-displacement behavior of piles subjected to static lateral and axial loads considering soil-pile interactions. The objective of the study in Part A is to develop a PTPC connection design capable of producing adequate moment capacity of the pile by relying only on plain pile embedments without any special connection reinforcement details. The present study evaluates the local and global behavior of the PTPC connections with plain pile embedment through Finite Element Analyses (FEA).

Show moreThe purpose of this dissertation research is to examine the perspectives of early childhood teachers with regard to multicultural education in South Korea. This study sought to identify teachers’ personal and professional beliefs about multicultural education as defined by their perceptions, descriptions, feelings, judgments, memories, and discussions with others. To better understand early childhood teachers’ perspectives of multicultural education in South Korea, the following research questions serve as a compass for the study: (a) What are South Korean early childhood teachers’ understandings and beliefs about multicultural education in their classrooms? (b) How do South Korean early childhood teachers implement multicultural practices in their classroom environment and curriculums? Findings show that teachers recognized a need for multicultural education because of the increasing diversity in South Korea. Although they understood embracing diversity, they shared opposing views about multicultural families while recognizing their bias as a challenge in the classroom. Teachers were unaware of the significance of the classroom environment and its influence on multicultural teaching, adding multicultural materials to accommodate children from multicultural families rather than actively integrating multiculturalism in curriculum and instructional interactions. Implications suggest avenues for increased multicultural understanding through teacher preparation, professional development, curricular revision, and policy changes.

Show moreCollege students with Intellectual Disabilities (ID) are afforded many educational opportunities through Inclusive Post-Secondary Education (IPSE) programs, including employment training. Competitive employment can contribute a rich independent life, thus more employment training opportunities can be beneficial. Low employment rates for adults with ID have motivated these efforts to develop proper employment training. In the past, on-the-job (OTJ) training with a job coach was one of the only supports for adults with ID in the workplace. Now, there are a variety of evidence-based strategies that can be used in the workplace or in other community settings, such as Covert Audio Coaching (CAC), to teach adults with ID the skills they need to maintain a job. This study used a multiple probe design to examine the effects of CAC on teaching workplace communication skills to college students with ID in a real-world setting. In this study, students interned in an office setting and spoke to a co-worker at their work setting while the interventionist used a two-way radio system to provide coaching statements to the student during their conversations. All students in this study increased their on-topic communication exchanges, and these results demonstrate that CAC is an effective intervention for this population.

Show moreStony coral tissue loss disease (SCTLD) emerged in 2014 and has since spread across Florida’s Coral Reef (FCR) and the Caribbean. This thesis is part of a larger project assessing the efficacy of restoring SCTLD-susceptible corals Montastraea cavernosa, Orbicella faveolata, and Pseudodiploria clivosa in SCTLD endemic areas. As part of Florida’s largest coral restoration experiment to date, 1,152 cement bases with 5,760 coral fragments from 99 source colonies were outplanted across six regions throughout FCR and monitored monthly over two years for survival, disease, and growth. Before outplanting, coral tissue samples were collected for high-resolution 2bRAD and ITS2 sequencing to genotype the corals and characterize their initial algal symbiont communities. Neither host genetic lineages nor algal symbiont types significantly affected SCTLD susceptibility or survival, negating the hypothesis of SCTLD-resistant “super coral” lineages. Results from this study will inform the feasibility and design of future coral restoration efforts in SCTLD endemic zones to maintain or enhance coral biodiversity.

Show moreEpilepsy is a prevalent brain disorder that affects more than 1 in 26 people in the United States. The recurring increased neuronal excitability during seizures results in sleep disturbances and muscle convulsions that reduce the quality of life and increase the healthcare costs for these patients. An epilepsy diagnosis is made when patients have had two or more seizures. There are many types of seizures and an individual can have more than one type. Seizures are classified into two groups, 1) generalized seizures that affect both sides of the brain and 2) focal seizures that are located in just one area of the brain. The causes of epilepsy vary by the age of the person, some with no clear cause may have a genetic form of epilepsy. Due to the various causes and types of seizures, many treatments including invasive surgeries and antiepileptic drugs (AEDs) do not work for all epileptic/seizure patients and are merely used to ease symptoms. The physiological complexity of the disorder and limited knowledge on its specific molecular mechanisms may contribute to the lack of effective treatment. In recent years, there has been an estimated average cost in billions of dollars to bring new medicine to the market; due to the lack of novel antiseizure targets and mechanism-based therapies on seizure phenotypes. In response to this, we utilized the electroconvulsive seizure behavioral assay to characterize one generalized seizure phenotype, tonic-clonic/grand mal seizures.

The fluke matures and reproduces within terrapins and, therefore, relies on terrapins for dispersal. Thus, we hypothesized that the genetic structure of flukes would reflect contemporary changes in the connectivity of terrapin populations. Flukes were sampled by dissecting mudsnails collected from eight sites along the eastern United States. Following amplification of the COI mitochondrial marker, 21 haplotypes were identified and a high degree of structure was detected. We propose that this suggests the parasite could serve as a tool for monitoring terrapin populations. This study sets a foundation for the genetic diversity of the fluke, and provides a first step towards developing the species as a proxy for studying terrapin population size, connectivity, and health, which may help conserve both species.

In this two-essay study, I examine how common owners interact with firms to make decisions and how they moderate the impact of market manipulation on corporate culture. In the first essay, I examine whether firms in the same industry make similar investment and financial policies when their large institutional owners overlap. This relationship is important given the tremendous rise of common institutional owners and their significance on their portfolio firms’ policies. I hypothesize that common institutional owners cause their portfolio firms in the same industry to make similar policies by creating anti-competitive incentives, reducing information asymmetry, and influencing governance.

Show moreSince 2005 corporate managers must discuss their firm’s significant risk factors that may materially and unfavorably affect corporate outcomes in the Item 1A Risk Factor Disclosure (RFD) section of their 10-K filings. However, there is limited research on whether firms change the sentiment of their mandatory disclosures after a significant economic event. I use bankruptcy announcements as a unique setting in this study to assess non-announcing firms’ responses to these events as a bankruptcy announcement generates significant concern to non-announcing industry peer firms. I explore whether industry peers change four measures of sentiment (i.e., length, negative tone, specificity, forward-looking statements) of Item 1A RFDs after a rival firm’s bankruptcy filing. Using textual analysis methodology, I find that industry peer firms have shorter, less negative, and less forward-looking RFDs after another firm’s bankruptcy announcement. These results imply that industry peers are likely to adjust their tone of mandatory filings (i.e., Item 1A RFDs) in response to a rival firm’s bankruptcy announcement. I further provide evidence that firms do not use separate subsections to disclose their firm- and industry-specific risks within their Item 1A RFDs. Lastly, the lengths of financial, litigation, other-idiosyncratic, and other-systematic topic disclosures significantly decrease for non-announcing industry peers while the length of tax relevant risk topic does not significantly change after a bankruptcy filing. This study adds to mandatory research by identifying the spillover effect of a bankruptcy announcement on Item 1A RFDs. This research also contributes to accounting literature by providing evidence that non-announcing industry peers significantly adjust the sentiment of their risk factor information. Market participants including investors, shareholders, and financial analysts can improve investment decision accuracy by analyzing the industry peers’ risk factor information.

Show moreThe study explored whether middle school students’ select academic (grade point average [GPA], Accuplacer mathematics, reading, and writing scores, admission interview scores) and non-academic characteristics (race, ethnicity, the middle school they attended, their gender, their parents’ educational level) have any predictive power with regard to their success at an early college high school. This study compared binary logistic regression (BLR) and predictive discriminant analysis (PDA) statistical models. First-year early college academic success can be predicted using BLR and only six input factors from middle school (Accuplacer math scores, interview scores, gender, and race, as three dummy variables) with a 91% accuracy. However, a student academic success prediction model using middle school data for a student’s first year college success could not be built. This finding asserts Astin’s Student Development Theory (1993, 1999a, 1999b), the theoretical framework that guided this study, that students can grow and improve over time and educators need to focus on cultivating and developing students’ smartness through high level instruction and coaching instead of identifying and celebrating smartness by accepting only the most prospective students into colleges (Astin, 1977, 1993, 1999a, 2017, 2018).

Purchasing human remains is illegal in Georgia, Louisiana, and Tennessee as well as prohibited by Facebook terms of service, but these sales persist. Over the course of 2021, 319 listings for human skeletal remains were recorded across six Facebook groups. These listings accounted for most skeletal elements found within the human skeleton. Many elements are artistic in nature, something viewed as “Giving a second life” to the remains, as observed within these groups. To fully understand the driving force behind this market requires cultural insight about the perception of human remains as well as the culture found within these groups. Kinship, friendship, and trust are all clearly expressed between buyers and sellers.

In this context, equitable accountability is defined as a measure more of the school’s impact on student achievement and less a measure of the socio-economic status of the students enrolled in the school. To do this, the study begins with a review of the history and current state of school accountability policies in the US and its relation to the concepts of school improvement, between accountability and student achievement, a review of accountability policy in each state and the possible future model of accountability policy. This study uses both qualitative and quantitative methods with a policy analysis informing state correlational comparisons, which in turn informed the models to be applied to the Florida data to identify how they perform (correlate), culminating in the development of a new school accountability model. The policy analysis revealed current school accountability in all 50 states and the District of Columbia as well as the relationship between socio-economic status and school accountability in each where data were available. Five of these state models were shown to be significantly less related to socio-economic status than Florida. However, only two of these models performed similarly when applied to Florida data. Finally, a model was proposed that included aspects from these states and available literature that performed similarly to these two states. This study represents an important first step in a larger policy discussion of how to hold schools accountable for their impact on students and not a measure of the demographics of the students they are serving.

With the advent of newly and more reliably designed targeted therapy methods in the past several years, targeted radionuclide therapy has attracted more attentions around the world as a more reliable treatment modality in combination with other well established traditional cancer treatments i.e., external beam radiotherapy and chemotherapy. Alpha particles have a high relative biological effectiveness (RBE) due to their high linear energy transfer (LET). However, to utilize them for...
Show moreWith the advent of newly and more reliably designed targeted therapy methods in the past several years, targeted radionuclide therapy has attracted more attentions around the world as a more reliable treatment modality in combination with other well established traditional cancer treatments i.e., external beam radiotherapy and chemotherapy. Alpha particles have a high relative biological effectiveness (RBE) due to their high linear energy transfer (LET). However, to utilize them for therapeutic purposes, precise human body dosimetry calculation is required. The measurement of their uptake and biodistribution can be quite challenging. Also, due to the complex biology of different types of cells, their shapes and functions, there is not a simple and clear understanding of the mechanism of action that fits all. This study aims to estimate and compare the human organ dosimetry of the alpha emitter, 212Pb, from animal data assuming that it is conjugated with three different types of commonly used targeting nanoparticles. For this purpose, the pre-published animal data of three different radionuclide labeled peptide, antibody, and small molecule carriers were selected and converted to human data. Then a compartmental model was designed for each of them to fit the model to the human data with 212Pb, half-life of 10.64 hours. Once each model reached the desired fit, the area under the curves were extracted then the estimated human organ dosimetry calculations took place via the MIRD scheme. The organ dosimetry results for 212Pb + three different carriers are presented in Tables 14, 17, and 20.

Rapid and efficient vascularization is still a considerable challenge of a tissue engineered β-tricalcium phosphate (β-TCP) scaffold. To overcome this challenge, branched channels were created in the porous scaffold to stimulate the instant flow of blood supply. The branched channeled porous β-TCP scaffold was fabricated using 3D printing and template-casting method. Human bone mesenchymal stem cells (hBMSC) and human umbilical vein endothelial cells (HUVEC) were seeded in the scaffolds and...
Show moreRapid and efficient vascularization is still a considerable challenge of a tissue engineered β-tricalcium phosphate (β-TCP) scaffold. To overcome this challenge, branched channels were created in the porous scaffold to stimulate the instant flow of blood supply. The branched channeled porous β-TCP scaffold was fabricated using 3D printing and template-casting method. Human bone mesenchymal stem cells (hBMSC) and human umbilical vein endothelial cells (HUVEC) were seeded in the scaffolds and characterized through double-stranded DNA (dsDNA) assay, alkaline phosphatase (ALP) assay and cell migration. Scaffolds were then implanted in the subcutaneous pockets in mice. Hematoxylin and eosin staining and Immunohistochemical staining on vascularization, bone-related markers were carried out. Results showed that branched channels significantly promoted HUVECs’ infiltration, migration, proliferation, and angiogenesis and also promote the proliferation and osteogenesis differentiation of hBMSCs. Scaffolds did not show significant pro-inflammatory effects. In vivo results showed that in the early stage after implantation, cells significantly migrated into branched channeled scaffolds compared to non-channeled and straight channeled scaffolds. More and matured blood vessels formed in the branched channeled scaffolds compared to in non-channeled and straight channeled scaffolds. Besides promoting vascularization, the branched channels also stimulated the infiltration of bone-related cells into the scaffolds. These results suggested that the geometric design of branched channels in the porous β-TCP scaffold promoted rapid vascularization and potentially stimulated bone cell recruitment. To further enhance the function of the scaffold to promote the MSCs differentiation, MnO2 hollow and solid nanoparticles were doped into the scaffold with different concentrations.

Show moreThis thesis serves as an exploration of the environment in James Joyce’s Ulysses which holds accountable the violent material politics of England against Ireland and the acts of consumption committed against human and nonhuman bodies, which is a radical critique of the patriarchal discourse and action that decimated a once sovereign nation and its landscape. I argue through an eco-critical lens that intersects the human body, a once impenetrable landscape, and the elision of Brehon Gaelic law as a victim of colonial usurpation. There is a deep focus geared towards masculinity and its imposition upon the female body, but also an important look at the relationship between man and nature. While sexuality and nature co-exist in Ulysses, we can envision this novel as an “epic of living with animals" and their human predecessors.
