The primary aim of this research is to deepen understanding of how influencer discourse shapes follower discourse, identifying recurring patterns, contradictions, and the ways in which tensions are negotiated. The findings reveal a range …

"Am I A Man Or A Muppet": A Rhetorical Analysis Of Generative Ai’S Representation Of Gender, Jessica Boaz

Electronic Theses and Dissertations

This thesis examines how generative artificial intelligence constructs and performs gender roles through a rhetorical analysis of the fully AI-generated podcast Fairytale Forensics. Drawing on theories of constitutive rhetoric, stereotyping, and McLuhan’s approach to the medium, this thesis investigates how AI-generated hosts interpret classic fairy tales while simultaneously reproducing and negotiating gender norms through the lens of prosopopoeia, metonymy and synecdoche. These performances rely on normative gender stereotypes that align with broader societal expectations, thereby potentially reinforcing existing cultural assumptions about masculinity and femininity. Ultimately, it demonstrates that AI-generated discourse does not merely reflect human biases but actively participates in …

Arthur The Knight-King: Protector Of Land, Preserver Of Culture, John Anthony Edwards Ii

Electronic Theses and Dissertations

The study of Arthurian literature has evolved and changed drastically over the past few centuries. The methodologies and research on King Arthur have taken a variety of approaches and covered all manner of topics, such as the Celtic roots of Arthuriana or discussion of ideals like chivalry. However, the discussion of Arthur’s character has stagnated due to the prevalence of discussing the ideology of kingship or the historical validity of a man called Arthur. A view of Arthur’s character as examined by the canon as a whole has yet to be explored. This thesis presents a new mode of interpretation, …

Fixed Perimeter Analogues Of Some Partition Results, Gabriel Gray, Emily Payne, Holly Swisher, Ren Watson

School of Mathematical & Statistical Sciences Faculty Publications

Euler's partition identity states that the number of partitions of n into odd parts is equal to the number of partitions of n into distinct parts. Strikingly, Straub proved in 2016 that this identity also holds when counting partitions of any size with largest hook length (perimeter) n. This has inspired further investigation of partition identities and inequalities in the fixed perimeter setting. Here, we explore fixed perimeter analogues of some well-known partition results inspired by Euler's partition identity.

Using 2-min photometric time-series data, we applied an automated algorithm to generate Lomb–Scargle periodograms and identify the most significant coherent periodic signals, which were subsequently verified through visual inspection. This process yielded a confident sample of 910 sources exhibiting at least one periodic signal, hereafter referred to as the Cataclysmic Variable Confident Catalogue (CCC). For each object, we report the most likely orbital period together with …

Noncanonical Clock Regulators Control Stress Responses In Digestive Diseases, Dishu Zhou, Roberto E López-Valiente, Samer G Mattar, Dongyin Guan

Faculty, Staff and Students Publications

The digestive system is essential for nutrient absorption, processing, and waste elimination. The expression of many genes and physiological processes within this system exhibits a 24-h rhythmicity. However, modern lifestyle factors, such as jet lag, shift work, and irregular eating patterns, significantly disrupt these rhythms, triggering various stress responses and contributing to numerous digestive disorders. Here, we focus on emerging studies on noncanonical clock regulators involved in stress responses, integrate these novel findings into the established model of the core circadian clock, and highlight recent advances in the development of novel therapeutics targeting these 24-h regulators. In addition, we discuss …

Faculty, Staff and Students Publications

Childhood obesity is rising and leading to serious co-morbidities, among which is metabolic dysfunction-associated steatotic liver disease (MASLD) predisposing individuals to cirrhosis. We describe a young 11-year-old Hispanic male who presented with hepatopulmonary syndrome secondary to cirrhotic portal hypertension from metabolic dysfunction-associated steatohepatitis (MASH), necessitating liver transplantation. Despite lifestyle modifications post-transplantation, the patient experienced persistent weight gain and recurrence of steatosis, emphasizing challenges of managing pediatric MASLD. The burden of childhood obesity is increasing and impacting children significantly earlier than previously believed. Our case is one of the few to report the severe complications of MASH in a young, pre-teen …

Case Series: Joubert Syndrome And Eosinophilic Esophagitis, Jonathon Schening, Stephanie Leon-Paredes, Eric Chiou, Vibha Szafron, Anthony Olive, Sara Anvari

Faculty, Staff and Students Publications

Joubert syndrome (JS) is a rare genetic disorder characterized by developmental abnormalities, particularly in the brainstem and cerebellar vermis, alongside multisystem manifestations such as kidney and liver anomalies, polydactyly, cleft lip or palate, and tongue defects. The underlying ciliopathy causing JS may also contribute to gastrointestinal symptoms and immune dysregulation via Wnt signaling and impaired epithelial maintenance. Dysmotility including Hirschsprung disease has been documented at increased rates in JS and in other ciliopathies. Our case series highlights how JS patients frequently exhibit feeding intolerance, vomiting, and poor growth, which may raise suspicion for an underlying gastrointestinal condition, such as eosinophilic …

Fructose: Metabolic Signal And Modern Hazard, Richard J Johnson, Miguel A Lanaspa, Dean R Tolan, Marcus D Goncalves, Samir Softic, Kimber L Stanhope, Laura G Sánchez-Lozada, Mark A Herman, Joshua D Rabinowitz

Faculty, Staff and Students Publications

There is much interest in the role of sweeteners such as table sugar (sucrose) and high-fructose corn syrup in obesity and metabolic disease. Both sweeteners consist of glucose and fructose, two six-carbon isomeric sugars. Whereas glucose ingestion may promote obesity through its effects to stimulate insulin secretion, fructose has unique metabolic effects that promote triglyceride synthesis and fat accumulation. These effects arise from fructose's well-known role as a signal of metabolic plenty. Under modern conditions of overnutrition, chronic excess fructose drives features of metabolic syndrome. Emerging evidence further links fructose to cancer and dementia. Here we review the biochemical, molecular …

A Phenomenological Study Of Teachers Who Use Oral Reading To Foster Student Reading Fluency And Engagement, Donyetta Grimes

Dissertations

The National Reading Panel (2000) recommends oral reading instruction as a means to improve overall reading fluency and reading comprehension. Oral reading fluency is a necessary foundational skill, and students who have not mastered it by the end of third grade, when students transition from learning to read to reading to learn, become struggling adolescent readers (Ming, 2018). Furthermore, there is a lack of research on reading fluency past the primary grades (Makebo et al., 2022). Additionally, research gaps exist when considering teachers’ actual practices during reading instruction (O’Sullivan et al., 2009). This gap is particularly concerning considering that teachers …

Restorying The Reader: Adolescent Narratives Of Identity, Context, And Motivation, Jennifer R. Gardner

Dissertations

This present study examined how adolescents narrate their reading experiences and what those narratives reveal about reading identity, motivation, and engagement. This study responds to a persistent problem in literacy education: adolescent reading is often framed through disengagement or reduced to isolated constructs, while students’ lived reading experiences across school, home, digital, linguistic, and social contexts remain underexamined. Guided by Self-Determination Theory, Intersectionality, and Reader Response Theory, this study centers on adolescent voices and treats these participants’ stories as the primary avenue of understanding how they experience and interpret their reading lives and selves. Data were collected through narrative interviews, …
