In The Search Of Cosmopolitan Literacies: A Case Of Formerly Expatriated Language Teacher, Asiye Demir

Theses and Dissertations

Cosmopolitanism refers to becoming a world citizen who can live harmoniously with different cultures. Today, our classes in the United States have become diverse daily. While we teach students who can speak more than one language, our teachers are primarily monolingual and monocultural. Hence, teachers who can speak multiple languages are celebrated in the system (Pacheco et al., 2019). Expatriation refers to teacher mobility that can entail learning other languages and being exposed to different cultures. Expatriation, as a form of travel, is an essential construct for cosmopolitan literacies because cosmopolitan dispositions can be developed through traveling (Molz, 2006). Thus, …

Unpacking The Relationship Between Legitimacy, Procedural Justice, Identity, And Desistance, Qassim Bolaji

Theses and Dissertations

Knowing why people stop offending over time and the criminal justice agencies' role in this process is essential for designing effective crime control interventions. Legal authorities have the core function of ensuring that social norms and laws are obeyed. However, the coercive and punitive tactics that police, judicial, and penal authorities typically resort to have been shown to have only limited impact on controlling and preventing crime while having the unintended consequence of worsening the public's perception of their institutional legitimacy. Specific to policing, the use of coercive policing tactics and their perceived ineffectiveness has, in recent decades, led to …

Native American Nationalism: Chickasaw Identity And The Music Of Jerod Impichchaachaaha' Tate, Austin Davis

Theses and Dissertations

Native American nationalism in classical music has yet to be seriously researched and is not taught in music academia. One of the more well-known contemporary Native American composers is Chickasaw composer Jerod Impichchaachaaha’ Tate (b. 1968). Throughout his career, Tate has explored and expressed his identity as a Native American and Chickasaw citizen through his music. As a result, his compositional output is a rich resource for examining what Native American nationalism in classical music looks like and how it is utilized in his works.

In this document, I analyze three of Tate’s pieces written for orchestra: Tracing Mississippi, Ghost …

Crystal Plasticity Modeling Of Heterogeneous Microstructure Of Additively Manufactured Metals, Md Mahabubur Rohoman

Theses and Dissertations

Additive manufacturing (AM) has emerged as a promising technique in the manufacturing industry for producing complex metal components as it provides shape freedom and simplistic processing chain.

Powder bed fusion is the widely used AM technique that uses laser or electron beam as the energy source to melt the metal powder and deposit it in a layer-by-layer fashion. While doing so, the previously molten layers are constantly are in re-heating and re-cooling processes which end up creating an intricate solidification for the deposited layers. Due to the complexity involved in the thermal cycles for the solidification process, columnar grains develop. …

Statistical Inference Based On Elliptically Symmetric Distributions For Directional Data, Zehao Yu

Theses and Dissertations

Directional data arise in many scientific fields such as meteorology, oceanography, geology, zoology, and biomechanics. Geometrically, directional data lie in a spherical space. Although not in a spherical space, compositional data, such as microbiome data, can be mapped from a simplex to a spherical space via the component-wise square-root transformation. Other examples where compositional data emerge as a subject of interest include compositions of minerals in rocks, compositions of chemical mixtures, investment portfolios, and demographic composition of a population. This dissertation aims to develop inference procedures for analyzing directional data in general initially, with later focus shifted to the transformed …

Enslaved Women: Reproductive Choices And Medicine, Adedoyin Adekunle

Theses and Dissertations

Enslavement in the American South persisted as a form of subjugation that endured into the nineteenth century. The origins of slavery stemmed from enslavers’ aspirations for dominance. This compelled displacement involved the removal of Africans from their native lands and their subsequent transport as chattels to America. Slavery gave rise to paternalism, an attempt to justify exploitation to resolve the fundamental contradiction inherent in slavery. Paternalism gave rise to the false idea of ultimate submission, which historians have agreed that most enslavers never attained because of slave resistance. However, the study of slave resistance had been primarily focused on enslaved …

The Northern View Of The Southern Shore: Experience, Reconciliation, And Commemoration In Postbellum Charleston, South Carolina, Michael Edward Scott Emett

Theses and Dissertations

This dissertation explores the experiences and commemorative practices of nearly 200 northern passengers in Charleston, South Carolina, as they attended the flag reraising ceremony at Fort Sumter on April 14, 1865, and then organized the Sumter Club to celebrate that event annually. While some has been written about postwar Charleston during the first half of 1865, and a little more has been published covering this flag ceremony, the Northern view and their experiences with each have not been investigated, nor has anyone written an account of this club. This dissertation utilizes the theory and methodology of the history of experience, …

South Carolina School District Takeover: A Critical Policy Analysis, David Osworth

Theses and Dissertations

School takeover is a reform strategy where a school or district is placed into the control of a state or municipal government agency. Takeover has become increasingly popular in many states as an attempt to improve schools and district that are struggling either academically or financially. Takeover, however, is more likely to be implemented in districts serving a higher proportion of Black students. Due to the racialized nature of this policy this study uses a Critical Race Theory (CRT) methodology to engage in a critical policy analysis of school takeover in one rural school district in South Carolina. This study …

Three Essays On Financial Institutions And Financial Intermediation, Xinxin Zhang

Theses and Dissertations

In the first essay, I examine the trading relationship between the manager of a collateralized loan obligation (CLO) deal and the borrowers and/or lenders of the underlying portfolio of the CLO deal. I investigate how these relationships affect the structure and pricing of CLO deals. I find that a stronger relationship between a CLO manager and either borrowers or lenders of loans in the underlying portfolio leads to a smaller equity tranche in the CLO deal and a lower yield spread of the AAA tranche, on average. These results suggest that the CLO manager uses private information from trading relationships …

Unraveling The Impact Of The School-To-Prison Pipeline: Investigating Racial Disparities In Disciplinary Practices, Zelexis Croffie

Theses and Dissertations

The Impact Of A Professional Learning Community On Direct Care Staffs’ Self-Efficacy In Promoting Social—Emotional Learning Skills, Tiffany Drahota

Theses and Dissertations

This qualitative collective case study documented three early childhood educators’ participation in a professional learning community (PLC) focused on promoting children’s social–emotional skills. Particularly, it illuminated the impact of a PLC on the direct care staffs’ self-efficacy related to the promotion of the specified skills. Self-efficacy strongly predicts a person’s willingness to persist through challenges, attempt a new task, and exert sufficient effort toward completion. Self-efficacy is highly influenced by social factors including peer observations and discourse (Bandura, 1977). PLCs are a form of professional development that focuses heavily on social interactions such as communication, collaboration, and group goal setting …

Quantification Of Immunometabolite Derived Protein Modifications During Mitochondrial Metabolic Stress, Justin Hunter Cox

Theses and Dissertations

The immunometabolite itaconate accumulates during lipopolysaccharide (LPS) stimulation of macrophages and microglia. Itaconate non-enzymatically reacts with cysteine residues to generate 2,3-dicarboxypropylcysteine (2,3-DCP), referred to as protein dicarboxypropylation. The tricarboxylic acid (TCA) cycle metabolite fumarate non-enzymatically reacts with the amino acid cysteine to form S-(2-succino)-cysteine (2SC), resulting in irreversible protein succination. Since fumarate and itaconate levels dynamically change in activated immune cells, the levels of both 2SC and 2,3-DCP reflect the abundance of these metabolites and their capacity to modify protein structure and function. I generated esters of 2SC and 2,3-DCP from protein hydrolysates and used stable isotope dilution liquid chromatography-tandem …

Our primary objective was to look beyond the stereotypical perception of Barbie as a two-dimensional figure and shed light on the diverse and complex discussions surrounding her cinematic representation. …

Becoming Musical: Towards A Typology Of Non-Musical Sounds In Recorded Popular Music, Jacob David Mccooey

Theses and Dissertations

There are many instances in popular music in which traditionally non-musical sounds are used musically. There is currently no research on the types and functions of non-musical sounds used musically (NMSUMs). I have collected and organized a collection of example tracks that contain these NMSUMs and analyzed their functions to determine a typology of these sounds. The analysis of the NMSUMs focused on intertextuality, intratextuality, form, texture, and how the sounds relate to traditional, musical sampling. Throughout the course of the analysis, several trends were distinguished amongst the many tracks gathered, and these trends form the basis of the typology.

Global Well-Posedness Of Nonlocal Differential Equations Arising From Traffic Flow, Thomas Joseph Hamori

Theses and Dissertations

Macroscopic traffic flow models describe the evolution of a function ρ(t, x), which represents the traffic density at time t and location x according to a differential equation (typically a conservation law). Numerous models have been introduced over the years which capture the phenomenon of shock formation in which the solution develops a discontinuity. This presents difficulties from the standpoint of mathematical analysis, necessitating the consideration of weak solutions. At the same time, this undesirable mathematical behavior corresponds to unsafe driving conditions on real roadways, in which the heaviness of traffic may vary abruptly and dramatically. This thesis introduces and …

Electronic Structure Investigation Of Photoswitch-Embedded Organic Frameworks And External Electric Field Effects On Carbon Dioxide, Austin Hill

Theses and Dissertations

Metal- and Covalent-Organic Frameworks (MOFs and COFs, respectively) are chemically versatile systems that have diverse applications, ranging from drug delivery to energy storage. This versatility is due to the highly tunable nature of organic frameworks, which utilize metal clusters, chemically diverse metals, and organic ligands. Researchers have recently demonstrated how MOFs and COFs can be remotely tuned through the use of photochromic organic linkers and light (Martin, et al., 2022). The implications of these findings are significant and have numerous applications, primarily in optical switching and energy storage. However, the photochromic mechanism within the organic framework must be investigated, which …

Simultaneous Crack & Wave Propagation And Acoustic Emission Signal Modelling Using Peri-Elastodynamic, Md Mushfiqur Rahman Fahim

Theses and Dissertations

This work presents the use of Peri-Elastodynamic, a guided wave simulation method based on meshfree non-local Peridynamics theory. To model simultaneous crack and wave propagation simulation and its application on Acoustic Emission (AE) signal modelling, a new formulation is presented. The field of nondestructive evaluation (NDE) and structural health monitoring (SHM) is slowly embracing the advancement in Machine Learning (ML) / Artificial Intelligence (AI) for better and cost-effective assessment of structures and damage prediction. AI/ML can revolutionize the NDE/SHM field by automating the data collection and analyzing processes. However, the big challenge is that the model needs a sheer amount …

Mental Trauma, Colonial Mimicry, And Internalized Racism In Tsitsi Dangarembga's The Book Of Not, Lily Kay Lynn Cook

Theses and Dissertations

Tsitsi Dangarembga’s second novel in her Nervous Conditions trilogy, The Book of Not (2006) emphasizes the disabling nature of colonial domination and terror through pain and violence inflicted on the body and the mind. Through the use of Frantz Fanon’s colonial and post-colonial theory and Homi Bhabha’s concept of colonial mimicry the critical nature of Tambudzai—the main protagonist—position in the novel becomes apparent. Just as the title suggests, the novel becomes a book of negation and unbecoming as Tambudzai tries to find her place as a woman in Southern Rhodesia while attending a European colonial institution while war rages just …

An Emic Conceptualization Of Veteran, “You're Either One Of Two Things; You're Captain America Or You're Broken”, Steven Wahle

Theses and Dissertations

The Global War on Terror (GWOT) conflicts have been sustained by an all-volunteer force for over 20 years. There have been no drafts, war bond drives, nor rationing. This is a departure from previous prolonged military conflicts in U.S. history. Volunteers with veteran status are often venerated publicly to express gratitude for their voluntary military service. However, the criterion for veteran status is inconsistent.

In the U.S., former military members tend to be regarded on one of two ends of a spectrum as archetypes in attempts to honor such service. On one end is the veteran hero veteran to be …

Méndez, Leigh G. Goetschius, Sarah Gareau, Kristin Ashford, Andrew J. Barnes, Katherine A. Ahrens, Kara Zivin, Elizabeth Mosley, Lu Tang, Writing Committee For Medicaid Outcomes Distributed Research Network

Publications

Background

Racial inequities in severe maternal morbidity (SMM) and mortality constitute a public health crisis in the United States. Doula care, defined as care from birth workers who provide culturally appropriate, non-clinical support during pregnancy and postpartum, has been proposed as an intervention to help disrupt obstetric racism as a driver of adverse pregnancy outcomes in Black and other birthing persons of colour. Many state Medicaid programs are implementing doula programs to address the continued increase in SMM and mortality. Medicaid programs are poised to play a major role in addressing the needs of these populations with the goal of …
