The Lumbee Tribe And Mmiwg2s: How A Crisis Hides Behind Unreported Data, Daniel Oxendine

Electronic Theses and Dissertations

The Missing and Murdered Indigenous Women, Girls and Two-Spirit (MMIWG2S) crisis has existed since European settlers first came to the continent and has the potential to affect all Indigenous communities in the United States (Schilling 2018). Despite what federal data shows, I argue that the MMIWG2S crisis affects the Lumbee Tribe based on conversations on MMIWG2S that are coming from the Lumbee community. The primary objective of this thesis research project has been to conduct exploratory research through a case study to understand how the MMIWG2S crisis affects the Lumbee Tribe of North Carolina. I use the critical lenses of …

(Dis)Invested Bodies: The Neoliberal Crafting Of Disability, T. Wesley

Electronic Theses and Dissertations

Using the Americans with Disabilities Act (ADA) as a unifying text, my dissertation explores the relationship between cultural production and the neoliberal crafting of humanity, the term I use to describe how social dimensions—including the construction of the textual and material body—become reorganized and governed through market relations. While many disability scholars and activists frame the ADA’s failures through social misunderstandings of disability, few have seriously attended to the limits of the ADA as a neoliberal fusing of economic governance and classical liberal individualism.

Tracing convergences between the ADA and earlier US disability legislation to socioeconomic and political reforms enacted …

Examining The Effects Of Post-Traumatic Self-Blame And Shame On Response To Laboratory-Induced Pain, Adi Rosenthal

Electronic Theses and Dissertations

Extant research has made clear the link between self-criticism and engagement in non-suicidal self-injury (NSSI). As posited by the Defective Self Model of NSSI, individuals who experience feelings of self-hatred may perceive pain as deserved and engage in NSSI (Burke et al., 2021). Individuals exposed to interpersonal trauma are at higher risk of engaging in NSSI, and also frequently experience trauma-related self criticism, namely shame and self-blame. More work is needed; however, to understand how self-critical post-traumatic cognitions contribute to risk for NSSI engagement for interpersonal trauma survivors. The current study uses a combination of lab-induced pain and self-report measures …

A Phenomenological Examination Of The Perception Of Psychopathological Misdiagnosis In Gifted Men, Tina Glass

Electronic Theses and Dissertations

While the exact prevalence of psychopathological misdiagnosis in gifted children is unknown, it is an occurrence within the gifted population (Amend & Beljan, 2009; Batstra et al., 2012; Bishop & Rinn, 2019; Bishop & Rinn, 2020; Coon, 2014; Webb et al., 2016). However, there is a gap in the literature related to psychopathological misdiagnosis specific to gifted males. (Desmet & Pereira, 2021; Ecklund et al., 2014; Eren et al., 2018; Neu & Weinfeld, 2007; OECD, 2015; Preckel et al., 2015; Watts, 2022). This transcendental phenomenological study leveraged Bronfenbrenner’s Bioecological Model for Human Development (Bronfenbrenner & Morris, 2006) as a theoretical …

An Archaeological Exploration Of Fatty's Place And Its Contribution To Early Tourism In The Garden Of The Gods, Aaron Anthony Acosta

Electronic Theses and Dissertations

In the Garden of the Gods Park, east of Gateway Rocks, Edwin “Fatty” Rice owned and operated a business that sold curios and offered amenities to visiting tourists. Fatty’s Place was the only establishment of its kind to exist on the grounds of the park. However, not much recognition has been given to Rice’s contribution to tourism in the Garden. This thesis uses archaeological exploration, especially ground-penetrating radar, framed by place theory to shed light on Rice’s involvement in the advent of tourism within the park. By providing three narratives, Rice’s place as imagined, as remembered, and as built, the …

Koopman-Based Modeling For Nonlinear Control Of Multirotor Uavs, Simone Martini

Electronic Theses and Dissertations

This PhD dissertation focuses on adopting the emerging Koopman Operator theory for modeling and nonlinear control of multirotor UAVs, focusing specifically on quadrotors for proof-of-concept demonstration purposes.

The Koopman Operator theory is based on the foundation that nonlinear dynamics in the state space may be represented as a linear evolution of some functions in the state space. Thus, using appropriately defined and possibly nonlinear functions of the state variables, called observables, as a new and maybe infinite set of coordinates that are referred to as lifted space, the original nonlinear dynamics appear to be linear. The implications of this theory …

Military, Political, Cultural, And Societal Implications Of The Islamic Republic Of Iran’S Passive Defense Strategy, Aaron R. Pilkington

Electronic Theses and Dissertations

Why did the Islamic Republic of Iran (IRI) adopt a passive defense strategy? This dissertation is the first to trace the institutional development of the IRI’s passive defense strategy and its two Islamic Revolutionary Guards Corps (IRGC)-led executive bodies: the Permanent Committee for Passive Defense (PCPD) and the National Passive Defense Organization (NPDO). Passive defense can be defined simply as defense without weapons, which includes all precautionary actions other than using weapons to minimize the effects of enemy hostile operations that increase deterrence, reduce vulnerability, sustain essential activities, promote national stability, and facilitate crisis management in the face of enemy …

Impact Of Dialogic Reading Intervention On Language And Literacy Development Of Young Dual Language Learners, Ekta Ghosh

Electronic Theses and Dissertations

There is a pressing need for research on early language intervention for dual language learners (DLLs) at risk of developmental delays, especially young children who are non-Spanish speakers. Despite the projection that 62% of the nation's children will be children of color by 2050, there is a significant research gap in this area (Lin et al., 2023). This study aims to fill this gap and recommend effective early language interventions for DLLs. The present study uses a single-case design to determine the impact of Dialogic Reading on vocabulary and alphabetical knowledge of preschoolers aged 36 to 60 months in English …

Utilizing Machine Learning To Forecast Sector-Level Equity Returns From Sector-Level Financial Ratios, Greg Kuppenheimer

Electronic Theses and Dissertations

Academics and equity analysts often utilize fundamental financial ratios to evaluate an industry's financial and operational performance. However, sophisticated econometric methods could be improved for estimating these ratios' importance in predicting sector-level stock return performance. To address this gap, gradient-boosted decision tree methods were applied to the WRDS sector-level financial ratio database to identify if financial ratios effectively forecast sector-level stock returns in future periods. The findings show that these ratios are predictive and economically material, both stand alone and in combination with other macroeconomic factors. Using these predictions, long and long-short sector-level portfolios were created, and most of these …

The Impact Of The First Language Usage For Chinese Undergraduate International Students, Qiunan Liu

Electronic Theses and Dissertations

English as the “lingua franca” serves as a bridge across diverse nations, cultures, and economies and plays an important role in modern society, which has increased the number of English language learners around the world. In the United States, over 30% of international students are from China, with the majority being undergraduate students. A significant number of Chinese students need to enroll in English learning courses when they attend universities in the U.S. due to insufficient English language test scores. Chinese international students often incorporate their first language (L1) when they are learning English in the U.S. Therefore, understanding the …

Developing A Comprehensive Cognitive Model Of Math Achievement, Nina Anderson

Electronic Theses and Dissertations

Recently, downward trends have been reported in U.S. children’s math performance following school disruptions during COVID-19 amidst longstanding concerns for instruction and curricula within the subject. In support of efforts to remedy these declines, the current work presents two studies dedicated to identifying cognitive factors that are most strongly related to math performance, and which therefore offer promising potential targets for assessment and intervention. Both studies use data from the Colorado Learning Disabilities Research Center, which includes participants ages 8 - 16 and multiple well-validated measures of all constructs of interest. Study 1 tests three alternative latent cognitive models of …

Akt Disruption Leads To Non-Canonical Apical Constriction In Drosophila Embryos, Vincent Brown

Electronic Theses and Dissertations

The Akt/mTOR pathway (Akt pathway) has largely been examined in terms of its role as the primary nutrient sensing pathway due to its ability to recognize nutrient availability within a cell, particularly amino acids and glucose. Among its nutrient sensing characteristics, this pathway also contributes to a large variety of other cell functions such as cell growth, proliferation, protein synthesis, and cell survival via anti-apoptotic signaling. Although many aspects of this pathway have been carefully studied, the extent to which it regulates embryonic development remains unclear. Here, I examine Akt function in the early Drosophila embryo and demonstrate that Akt …

The Effect Of Financial Disclosure Medium And Ceo Gender On Perceptions Of Overconfidence And Credibility, Sheryl Moriarty

Electronic Theses and Dissertations

I experimentally examine how investors react to an unexpected negative earnings announcement delivered using video versus audio by an overconfident female CEO versus an overconfident male CEO. The results show that the CEO's gender does not matter in terms of the delivery medium. I predict and did not find that CEO overconfidence is lower for a financial disclosure delivered by video as opposed to audio only. Further, the hypothesis that the perception of female CEO overconfidence is higher versus male CEO overconfidence was not supported. Overall, the participants in the study did not find either the male or the female …

On Salvation And Genre: Fast Sermons In Seventeenth-Century New England, Daniel Patrick Mcgee

Electronic Theses and Dissertations

The fast sermon is an important and overlooked genre in the literary history of colonial New England, one which complicates theories about American puritanism underwritten by the imprecise narrative construct of the jeremiad. This thesis will argue that preachers used fast sermons to shape their communities, respond to major events, and provide competing interpretations of Congregationalist doctrine throughout the seventeenth century. Borrowing from the methodologies of new formalist criticism and Louis Althusser’s theory of material ideology, it will examine common themes, motifs, and rhetorical demands in John Wheelwright’s 1637 Fast Sermon, Thomas Shepard’s 1645 Wine for Gospel Wantons, …

Settler Colonialism And Refusal Through Indigenous Eyes, Charlie Amáyá Scott

Electronic Theses and Dissertations

The educational system within the united states has benefited and continues to benefit from the structures and systems of settler colonialism. Yet, despite such colonizing goals of displacement, removal, and genocide, Indigenous Peoples are still here. This critical Indigenous qualitative research study sought to understand descriptions and interpretations of settler colonialism from the perspectives of Indigenous undergraduate students and how they have, refused settler colonialism while navigating their undergraduate journeys. Indigenous ways of knowing and ways of being were centered and cited in a manner that made this dissertation more than just a research study; it became a home where …

The …

Making And Breaking Bonds: Studying Intrinsic Chemistry In The Gas-Phase, Luke Metzler

Electronic Theses and Dissertations

The nature of chemical interactions can be difficult to ascertain in the condensed phase; chemistry can be observed, but with the plethora of variables such as solvation, mixes of counter-ions, and complex equilibria, the true intrinsic chemical properties of a given chemical species may be obfuscated. By conducting research in the gas-phase, many of these variables can be reduced, if not eliminated entirely, which can allow for the careful observation of the true physical phenomena driving chemical reactivity.

The research presented herein focuses on the use of ion-trapping (specifically in a linear ion trap) as a method for unveiling the …

Injectable Formulations For Localized Delivery Of Immunomodulators, Ketki Velankar

Electronic Theses and Dissertations

Dysregulation of immune homeostasis is fundamental to the development of autoimmune disorders. Fibroblastic reticular cells (FRCs) within lymph nodes play crucial roles in forming a microenvironment conducive to immune cell interactions and regulating autoreactive T cells driving autoimmune diseases. Studies have shown the potential of FRCs as a form of personalized cell therapy to correct dysregulated immune responses. Successful translational efforts, however, require the cells to be formulated as injectable suspensions while retaining their native architecture, which is essential for their regulatory functions. The main challenge resides in retaining the native reticular organization of FRCs lost in conventional monolayer cultures …

Being And Sacrifice: An Essay On Hegelian Logic, Mitch Thiessen

Electronic Theses and Dissertations

A study of Hegelian logic in relation to postmodern thought, this essay investigates the limits and contemporary significance of Hegel’s concept of knowledge, both on its own terms and from the perspective of three of its most polemical critics: Søren Kierkegaard, Friedrich Nietzsche, and Georges Bataille. Of especial consequence in this study are the themes of individuality, desire, history, and death, insofar as Hegel’s critics judge him to have inadequately come to terms with—and to have even suppressed—the truth or fact of these realities, all of which are potentially fatal for his theory of the subject.

The Ethical Duty Of Care For Suicide Ideation, Tah Ngijoi Yogo

Electronic Theses and Dissertations

With suicide being a leading global cause of death, there is a need to explore the ethical complexities surrounding suicide and preventive measures. This dissertation questions the morality of suicide by examining the historical and philosophical dimensions across cultures and religions. The text argues for an approach that acknowledges rational suicide while developing the ethics of paternalistic measures for suicide prevention of vulnerable populations.

Considering the ethics of autonomy, the dissertation discusses the practice of nudging in healthcare to highlight the role of paternalism in supporting informed consent. The text proposes an enhanced autonomy model that balances trust, influence, and …

Form And Matter In Kant's Theoretical Philosophy, Aaron Higgins-Brake

Electronic Theses and Dissertations

This dissertation examines the use of the terms “form” and “matter” in Kant’s theoretical philosophy from his earliest publications up to the Critique of Pure Reason (1781). I argue that these two concepts have received unfortunately little attention in the development of Kant’s thought and in his mature writings. I begin in Chapter One by examining his increasing use of them in his pre-critical writings culminating in the Inaugural Dissertation (1770), where he first develops his theory of space as a form of intuition. Then in Chapters Two to Five, I examine his account of them in his accounts of …

The Educational Experiences Of Children And Adolescents With An Ryr1-Related Disease, Jeremy Armann

Electronic Theses and Dissertations

This paper investigates the educational experiences of children and adolescents diagnosed with RYR1-related diseases, a spectrum of congenital myopathies affecting muscle function. Despite these conditions typically sparing cognitive abilities, they profoundly impact physical capabilities, presenting challenges in school environments such as participation in physical activities and social interactions. The study utilizes data collected through the RYR1-Related Disease Educational Impact and Satisfaction Survey (RDEISS) and the Behavioral and Emotional Screening System (BESS) from 49 parents of 51 children aged 3-18 years. Findings reveal prevalent classroom difficulties including handwriting issues and written expression difficulties, with 78% of children receiving special education services, …

The Impact Of Kangaroo Care (Kc) On Parent Stress, Infant Neurobehavioral Regulation, And Parent-Infant Attachment In Very And Extremely Preterm Infants, Justine Vecchiarelli

Electronic Theses and Dissertations

This study examines the high-risk population of infants born atinfants, developmental delays in infants, and parent-infant relationship disruption. Kangaroo care (KC) has shown promise as an intervention to buffer these adverse effects, however, KC engagement in NICUs is obstructed by lack of clear guidelines. Furthermore, limited research exists on KC including infants born atoutcomes, infant behavioral/developmental outcomes, and parent-infant relationship outcomes conjointly. The aim of this study was, therefore, to examine the impact of kangaroo care engagement on precursors of adverse outcomes including parent stress, infant neurobehavioral organization, and parent-infant bonding with the intent of informing clinical practice. Data was …

Macromolecular Crowding Effects On Enzymes That Display Non-Hyperbolic Kinetics, Kelsey A. Aldrich

Electronic Theses and Dissertations

Macromolecules occupy up to 30% of a cell's volume, yet the in vitro study of biological processes is almost exclusively performed in dilute solutions that fail to approximate the crowded interior of a cell. A growing body of literature has identified that macromolecular crowding has significant effects on a number of biochemical processes, including enzymatic activity. However, changes in kinetic parameters with increased macromolecule concentrations have only been determined for enzymes that follow hyperbolic Michaelis-Menten kinetics, despite the fact that over 25% of enzymes deviate from this model. Here, we perform the first characterization of macromolecular crowding effects on …

Structural Characterization Of The Puma Diapir, Gulf Of Mexico Basin, Rodrigo Velasquez

Electronic Theses and Dissertations

The Gulf of Mexico (GOM) Basin has been a significant target for oil and gas since the 1990s and continues today as a leading exploration target. This super basin is home to an estimated 200 BBOE (Billon barrels of oil equivalent), with current production totaling 60 BBOE for both USA and Mexico. Even though the overall depositional evolution of the GOM has allowed for the key elements for petroleum accumulations to be met, a complex structural framework is present. This framework results from the asymmetric spreading of the North American Plate from the Yucatan block crating the GOM basin we …

Self-Efficacy Towards Teaching, Critical Thinking Dispositions, And Supervision Of Teaching Among Ces Doctoral Students, Brenda Everett

Electronic Theses and Dissertations

According to the 2024 CACREP Standards (2023), “ethical behavior, diversity, equity, inclusion, and critical thinking” are essential for counselor preparation. Thus, doctoral students must be equipped to teach and incorporate “culturally sustaining content and strategies across the eight foundational curriculum areas” into counselor training upon graduation (Section 3, p.12). Given the increase in counselor education programs (Field et al., 2020) and the need for self-efficacious counselor educators (Association for Counselor Education and Supervision [ACES] Teaching Initiative Taskforce, 2016) in these programs to teach the next generation of counselors-in-training, there is a continuous need in the literature for research on self-efficacy …

The Impact Of “Multiple Looks” When Performing Survival Analysis, Quentin Eloise

Electronic Theses and Dissertations

Survival analysis is a critical statistical method in healthcare to assess patient treatment effects and disease progression. Another critical area of statistical methodology in health care is the practice of adaptive designs. Adaptive designs allow for interim analyses to take place during a study and various decisions and actions can take place more ethically. This is beneficial for studies that take multiple years to complete and allows administrators and healthcare providers to make sound decisions as early as possible. A challenging aspect of adaptive designs is that the number of interim analyses is known in advance which is applicable in …

Emotional Content In Working Memory Processes: An Fmri Study., Manal Zafar

Electronic Theses and Dissertations

Working memory (WM) is a dynamic system that processes and manipulates both goal-relevant and goal-irrelevant information, integral to higher-level cognition and executive control (Fujii, 2001; Nyberg & Erikkson, 2016). The processing and manipulation of representations is modulated by the affective nature of the information (Pessoa, 2009) such that negative information can either impair or enhance WM processing. WM impairments are seen commonly across clinical disorders such as depression, anxiety, PTSD and schizophrenia (Levens & Gotlib, 2010; Joorman et a., 2011; Brodziak et al., 2015). Specifically, negative information is known to have differential processing in WM compared to neutral and positive …
