Filing The Serial Numbers Off: The Role Of The Author In Fanfiction Published As Original Fiction, Lauren Mcinnis
All ETDs from UAB
With the increase of authors altering and publishing fanfiction as original works of fiction, the practices and attitudes of fan communities cross over into the realm of traditional fiction. Throughout its history, fandom is a community built on the shared love of a piece of media or celebrity. The importance of community appears in fanfiction through Author’s Notes and comments sections; both of which traditionally published novels generally lack. When authors choose to make the transition to traditional publication which provides legitimacy that fanfiction lacks, they must remove most of their own identity and the fan-community that they originally relied …

Mechanical Behaviors Of Additively Manufactured Fiber-Reinforced Thermoplastic Composites, Yu-Chao Shih
All ETDs from UAB
Additive manufacturing (AM) technologies are advantageous in small-batch manufacturing and prototyping functional parts, due to their cost-effectiveness and customizability. Using fiber-reinforced plastic composites (FRP) in extrusion-based AM can significantly improve the mechanical properties compared to neat thermoplastic. However, the two-fold anisotropy introduced by the multiple constituent materials and the layer-by-layer mesostructure can introduce undesired structural weaknesses. Investigating the mechanical behavior and failure mechanism is the key to understanding the synergistic effect of the constituents in FRP and assessing the structural integrity of AM-made FRP. This research work aims to experimentally, analytically, and numerically assess the mechanical behaviors of AM composite …

Insulin Responses, Diet Composition, And Fat Loss, Amanda Finn
Insulin Responses, Diet Composition, And Fat Loss, Amanda Finn
All ETDs from UAB
Some but not all studies show participants who have higher baseline insulin responses lose more weight on a low glycemic load compared to a high glycemic load diet. Most prior research tested the relationship between insulin and weight changes with only one insulin response variable, such as insulin from an orally or intravenously (IV) administered metabolic test. We tested whether insulin responses (IV or oral) predicted changes in body fat among participants undergoing diet-induced weight loss. This study was a secondary analysis of a clinical trial. In the parent study, participants were randomized to either a reduced carbohydrate (ReducedCHO) or …

Motor Development Of Individuals Referred For An Asd Evaluation, Timothy Gary Hilty
All ETDs from UAB
Autism spectrum disorder (ASD) is neurodevelopmental disorder that affects 1 in 36 children. Fine motor skill delays and deficits are a common occurrence among autistic individuals. Fine motor delays tend to present in toddlerhood and deficits tend to persist into adulthood. However, fine motor skill delays and deficits are not a component of the diagnostic criteria for an ASD diagnosis. While fine motor differences between autistic and typically developing individuals are well established, it remains unclear if these differences exist between autistic individuals and those with other neurodevelopmental disorders and whether they provide additional insight into diagnosing ASD more accurately. …

[Mis]Representing “India” And Other Colonial Territories In Donne’S Poetry: An Insight Into Colonialism’S Multifaceted Aspects, Urnisha Dutta
[Mis]Representing “India” And Other Colonial Territories In Donne’S Poetry: An Insight Into Colonialism’S Multifaceted Aspects, Urnisha Dutta
All ETDs from UAB
Colonial objects in Donne’s poems embrace multifaceted attributes, offering diverse reading perspectives. Considering their multifaceted aspects, it becomes impossible for a reader to ignore his poems’ interdisciplinary qualities. They often embrace philosophical, religious, political, and historical connotations. The colonial objects, appearing as “black” characters, silent women, or colonized territories in his poems, generate East-West binaries, Western subject consciousness, Eastern [mis]representations, world polarizations, and color contrasts. His female bodies’ misogynistic/sexual portrayal frequently ends in pulling up colonial references, associating their bodies with colonial landmasses. They often associate with his spiritual consciousness, complicating reading and textual interpretations. Critics thus cannot take a …

3d Microtissue Model Of The Aged Ovarian Tumor Microenvironment, Peyton Clark
All ETDs from UAB
Ovarian cancer is the 5th leading cause of cancer deaths for women, primarily due to treatment resistant and/or recurrent disease. Most cases of ovarian cancer are not diagnosed until distant metastases have formed, which drastically reduces overall survival. The median age at diagnosis is 63 and most cases occur in patients who are peri- and post-menopausal. There is a critical gap between the clinical presentation of ovarian cancer and the preclinical models used to study the disease. Most preclinical in vivo investigations use mice who are between 6 and 12 weeks old, which corresponds to roughly a 20-year-old human. Therefore, …
