The current investigation proposes a novel longitudinal mixed methods research design, explanatory fully longitudinal mixed methods case study design. It demonstrates its potential for addressing research inquiries in educational research using the arithmetic learning trajectories datasets. This study is presented in three components. The first is a quantitative phase, selecting an exploratory case from a previous arithmetic learning trajectories study (Clements et al., 2021) for qualitative analyses based on maximizing the …

Computational Fluid Dynamics And Fluid Structure Interaction Modeling In Healthy Vertebral Arteries: A Comparative Study, Bryce Clinkenbeard

Electronic Theses and Dissertations

Cerebral perfusion is critical for maintaining proper brain function, with each cerebrovascular artery playing an integral role in the overall cerebrovascular system. When these arteries become damaged or develop plaque, cardiovascular disease (CVDs) such as atherosclerosis can arise, leading to conditions like arterial stenosis. While CVDs are most prevalent in older individuals, they are also observed in young adults, particularly those engaged in high-endurance occupations such as military service. Diagnosis and prediction of CVDs often rely on imaging modalities supported by computational fluid dynamics (CFD) which account for low resolution in fluid flow. CFD models assume rigid arterial walls, which …

When Electrification Meets Reindustrialization: The First Eu Green Electric Vehicle Subsidies And The Wto Consistency, Mandy Meng Fang

Duke Journal of Comparative & International Law

The French Government recently reformed the "Ecological Bonus" scheme, which has generously supported its domestic consumers in purchasing electric vehicles ("EVs"), by introducing a new criterion based on the amount of carbon emitted in the vehicle's manufacturing. Starting in 2024, the scheme strictly sets the production carbon footprint ceiling at 14.75 tons of CO2, effectively denying the subsidy eligibility of more than one-third of EVs sold in France. Other European Union ("EU") Member States, including Italy, have considered taking similar policy actions. Criticized as the French version of the discriminatory United States Inflation Reduction Act, the new Ecological Bonus scheme …

Countering The Demand Side Of Foreign Bribery: An Analysis Of The Foreign Extortion Prevention Act, Noah Buyon

Duke Journal of Comparative & International Law

The United States has long criminalized bribery of foreign officials but not bribery by foreign officials. Under the Foreign Corrupt Practices Act ("FCPA"), an American may be criminally liable for paying a bribe to another country's official, but the official commits no corresponding crime. The official might face criminal charges if they launder the proceeds of the bribe through the United States and could find themselves the target of Executive Branch sanctions for their corrupt behavior. But until 2023, the United States largely left the official's punishment, if any, to the official's home country. Then, Congress passed the Foreign Extortion …

The Shōnen Apocalypse: An Analysis Of The Shōnen Power System And Its Narrative Functions, Mario Da Silva Melo

Electronic Theses and Dissertations

My thesis has two primary goals. First, it provides an overview of the history of manga as a medium, and manga studies as a field. In doing so, I observe a lack of terminological and methodological specificity. As a result, I provide a formalist approach to thematic criticism in order to address the above issues. Second, my thesis primarily centers on shōnen power systems and their narrative functions. Power systems are "magic rules" that determine how superhuman abilities mechanically function. I identify two main power systems in shōnen manga: spiritual manipulation and transformations. My thesis posits that shōnen manga authors …

The Embodiment And Experiences Of Gender Euphoria Among Transgender And Nonbinary Communities: A Mixed Methods Inquiry, Brendon T. Holloway

Electronic Theses and Dissertations

Gender euphoria is a critical aspect of embodiment for transgender and nonbinary (TNB) people that has long been overshadowed in academic research by deficit narratives and gender dysphoria. While gender dysphoria is the distress an individual may experience related to their gender, gender euphoria encapsulates the positive emotions a TNB person may experience because of positive gendered experiences. Despite community documentations of gender euphoria since the 1970s, academic research on gender euphoria has only recently begun to emerge. This three-paper dissertation advances this body of scholarship by exploring how gender euphoria is conceptualized, experienced, and embodied in TNB communities. Utilizing …

This research calls for reform grounded in transparency, comparability, and justice for …

The Narratological Maus, Isla Lader

Electronic Theses and Dissertations

The Complete Maus, a memoir graphic novel surrounding the events of character Art Spiegelman as he collects, records, and illustrates his father’s life pre-the Holocaust in Europe, his time in Auschwitz, and then life in the United States has been one of the focal Holocaust survivor testimonies and has redefined the genre it exists in as both a graphic novel, but also as a form of testimony. Like many popularized works dealing with the Holocaust, though, cultural preconceptions of Jewish people, genocide, and audiences’ desire to find morals within the work have made it so often audiences come to …

E Ho’Omau Mākau, We Will Continue: The Living Sovereign Entities Of Contemporary Hawaiian Songs, Kēhaulani Lagunero

Electronic Theses and Dissertations

This thesis examines the relationship between contemporary Hawaiian mele (songs) and Hawaiian ea (sovereignty), focusing on how mele acts as sovereign living entities representing cultural resilience, identity, and resistance to settler-colonial influences. Through semi-structured interviews with Kānaka Maoli, participant observation at cultural events, and close analysis of mele, I identify that these songs are not only expressions of cultural memory, but also living embodiments of ea—sovereignty because they are alive, and they are alive because they are ea. Drawing from the frameworks of cultural survival, survivance, symbolic power, and defiant indigeneity, I explore how mele actively engage …

Carbon Monoxide Releasing Polymeric Micelles, Riya Joshi

Electronic Theses and Dissertations

Carbon monoxide (CO), traditionally known as a toxic gas, has emerged as a potential therapeutic agent due to its cytoprotective, anti-inflammatory, and vasodilatory properties. This study explores the development of CO-releasing polymeric micelles as a controlled delivery system for biomedical applications. Using ring-opening metathesis polymerization (ROMP), we synthesized diblock copolymers incorporating CO-releasing moiety diphenylcyclopropenone (DPCP) with hydrophilic polyethylene glycol (PEG) to enhance solubility and stability of the overall CO releasing system. Dynamic light scattering (DLS) and electron microscopy (EM) confirmed the formation of well-defined micelles, while fluorescence assays demonstrated efficient CO release with the use of Iridium photocatalyst under 470 …

Longitudinal Relations Between Self-Esteem And Depression: A Continuous Time Analysis With Exploration Of Sleep Duration Effects, Mackenzie Cummings

Clinical Psychology Dissertations

Adolescents and young adults face elevated risk for depression. While poor self-esteem and sleep disturbance are known risk factors, few studies have examined their unique and interactive contributions. Longitudinal research often overlooks unequal intervals and multiple sources of variance (e.g., between- and within-person). This study used continuous time structural equation modeling to address these gaps and examine relationships between self-esteem, sleep duration, and depression from adolescence into adulthood. Drawing on four waves of data from the National Longitudinal Study of Adolescent to Adult Health (N = 6,184), I tested whether sleep duration moderated the self-esteem–depression link and explored gender differences. …

College of Science and Health Theses and Dissertations

This study investigates the impact that temperature-induced vertebral anomalies have on the C-start escape response of Astyanax mexicanus, a model species in evolutionary developmental biology. Employing three temperature treatments to induce varying degrees of skeletal anomalies, we assessed their effects on key swimming performance metrics including, C-start time, the curvature coefficient, head displacement distance, and displacement velocity. Through the use of linear mixed models (LMMs) and generalized linear mixed models (GLMMs), our results reveal that specific anomalies such as vertebral fusions and anomalous haemal and neural spines affected the curving ability of c-start escape responses, however, these did not negatively …

Zeeman Effect Observations Of Water Masers In The Star Forming Region Ngc 7129 Firs2, Marina Bethann Beltran

College of Science and Health Theses and Dissertations

Magnetic fields likely play an important role in star formation, yet their influence remains poorly understood due to the observational challenges in measuring them. The only direct method for measuring magnetic fields is through the Zeeman effect, the splitting of spectral lines in the presence of a magnetic field. Water masers, which trace high-density shocked regions, are known to occur throughout some of the earliest stages of the star formation process. They provide an excellent opportunity to observe the Zeeman effect. However, Zeeman detections in H2O masers have so far been limited primarily to isolated, high-intensity maser lines with simple …

1 Herpes Simplex Virus Type 1 And Apolipoprotein-E In Alzheimer’S Disease: Virus Entry And Innate Immunity, Jim Camilleri

College of Science and Health Theses and Dissertations

Herpes simplex virus type 1 (HSV-1) is a neurotropic virus that has been detected in brains affected by Alzheimer’s Disease (AD), the leading global cause of cognitive decline. In vitro and epidemiological studies support a role for HSV-1 in AD. The strongest genetic risk factor for late-onset AD is the E4 allele of APOE, which codes for apolipoprotein-E (ApoE), a protein that mediates brain cholesterol homeostasis. Previous work has suggested that ApoE can affect HSV-1 entry into cells; however, APOE has three alleles (E2, E3, and E4) and allelespecific effects of ApoE on HSV-1 entry remain undetermined. We hypothesized that …

A Multilevel Analysis Of Arrest For Sexual Assault In The United States: The Effect Of Incident, Police Department, And Community Factors, Erin Elizabeth Hoffman

College of Science and Health Theses and Dissertations

Police officers play an important role for sexual assault survivors seeking help from the criminal legal system in the United States. One of their main responsibilities is to investigate the crime to determine if there is enough evidence to arrest a suspect. Previous literature has documented police arrest decisions in sexual assault cases are influenced by legal and extralegal factors—factors that are legally relevant (e.g., presence of DNA evidence) and irrelevant (e.g., victim race) in a case. These factors span multiple levels of analysis, namely the incident (e.g., whether a weapon was used) and police department (e.g., % of woman …

Gi, Pain, Anxiety, And Mood Symptoms Among Youth With Fapds, Helen Bedree

College of Science and Health Theses and Dissertations

Pediatric functional abdominal pain disorders (FAPDs) frequently persist into adulthood, thus developmental considerations are critical for monitoring symptom presentation and tailoring treatments. In addition to core symptoms, such as pain and gastrointestinal symptoms, mood and anxiety symptoms often co-occur as well as negative impacts on functioning and quality of life. The current study took a developmental approach to assess core pain, gastrointestinal, anxiety, and mood symptoms among youth with FAPDs (N = 105), as well as agreement across youth and their caregivers on these key symptoms. Developmental stages included early childhood, middle childhood, adolescence, and emerging adulthood. A cluster …
