Fit Index Criteria For Multisample Analysis In Sem With Ordinal Data: A Monte Carlo Simulation Study, Suat Babayigit

Graduate Thesis and Dissertation post-2024

Measurement invariance is crucial for valid group comparisons in structural equation modeling (SEM), yet testing invariance becomes challenging when using ordinal data. This dissertation evaluates the adequacy of widely used fit index difference criteria (ΔCFI, ΔRMSEA, ΔSRMR) for multisample invariance testing with ordinal indicators. Traditional Δ fit cutoff thresholds were established based on continuous, normally distributed data, but ordinal measures can distort invariance conclusions. Monte Carlo simulations address this issue by manipulating a comprehensive set of conditions: sample sizes (200, 400, 1000), group size ratios (equal vs. unequal), model complexity (low vs. high), underlying distributions (normal vs. nonnormal), Likert scale …

Instructional And Motivational Factors Predicting Deep Learning Approaches In Pre-Clinical Medical Students, Kenneth L. Dearman

Graduate Thesis and Dissertation post-2024

Pre-clinical medical students predominantly employ surface learning approaches, focusing on memorization and exam preparation rather than developing a deep understanding of medical knowledge. This study employed a correlational design comparing two courses with different instructional approaches using expectancy-value theory to examine how instructional methods and motivational factors predict deep learning approaches among 148 pre-clinical medical students at a College of Medicine in the Southeastern United States. Initial results showed that the three separate constructs in task motivation (expectancy beliefs, values, and cost) did not mediate the relationship between active instructional methods and deep learning strategies. Instead, active learning was a …

Nou La, We Are Here: A Phenomenological Study On Haitian Students' Identity Development In College, Norma J. Altidor

Graduate Thesis and Dissertation post-2024

The United States has seen an increase of individuals migrating from Haiti in search of better opportunities for themselves and their families (Camarota, 2024; Ogunwole, Battle & Cohen, 2017). That rise has correlated with an increase in the number of Haitian students enrolling in American higher education institutions. There are many published studies on the experiences of minorities based on race (Harper & Quaye, 2007) compared to studies on ethnically diverse students (Dennis, Phinney & Chuateco, 2005). Existing literature shows that immigrant youth and first-generation Americans often identify more with their ethnicity than their race (Tatum, 1997). As such, there …

Investigating The Role Of Selenium-Dependent Stickland Reactions In Clostridioides Difficile Bioenergetics, Dominika Dzurny

Graduate Thesis and Dissertation post-2024

Clostridioides difficile is an anaerobic, spore-forming bacterium and one of the leading causes of antibiotic- associated diarrhea. Colonization depends on the metabolism of certain nutrients in the host gut, namely amino acids and carbohydrates. C. difficile ferments amino acids as an integral part of its metabolism via Stickland reactions, utilizing the selenoproteins D-proline reductase (Prd) and glycine reductase (Grd) to generate energy. Specificity of selenocysteine incorporation reflects the intracellular levels of selenophosphate, the activated selenium donor synthesized by selenophosphate synthetase (SelD). SelD is coincidentally a selenoprotein itself, containing a UGA codon at position 17 (Sec-17). The functional and physiological importance …

Creating An Archive From Colonial Records: Representations Of The Caribbean In British Periodicals, 1750-1930, Natalie B. Herman

Graduate Thesis and Dissertation post-2024

The periodization of Caribbean literature is a highly contested topic. Much of this periodization problem relates to the question of what should be included in this category of Caribbean literature, a question that became particularly pertinent during the postcolonial era. Many studies of Caribbean literature have traced its supposed origins to the period of the early to mid-twentieth century when many Caribbean territories were well on their way to postcolonial independence while disregarding works produced during the colonial period as they were considered to favor colonialism. Through examining how Caribbean literature appeared in the pre-1950 period, research conducted for the …

Interactions Of Anti-Viral Ceria Nanoparticles With An Enveloped Rna Virus, Muhammad Hassan Mehmood Kalyar

Graduate Thesis and Dissertation post-2024

There is growing interest in developing durable and broad-spectrum antiviral nanomaterials for surface disinfection. Silver-modified ceria nanoparticles (AgCNPs) are regenerative materials capable of inactivating a wide range of viruses through generation of reactive oxygen species (ROS). We hypothesized that for enveloped RNA viruses, the lipid bilayer and viral spike glycoproteins are determinants of sensitivity to inactivation of infectivity by AgCNPs. This hypothesis was tested using Vesicular Stomatitis Virus (VSV), a model enveloped negative-sense single strand RNA virus containing a single spike glycoprotein G. Five rounds of serial passage of VSV in the presence of suboptimal AgCNP concentrations led to the …

Exploring The Role Of Fatty Acid Signaling In Macrophages, Ayomide Ogunsanmi

Graduate Thesis and Dissertation post-2024

Dietary fatty acids play critical roles in both the gustatory and immune systems. In taste, they serve as the sapid molecules that underlie the ability to taste fat, whereas in the immune system, they serve as messengers that help facilitate the fuel-based reprogramming of macrophages (MΦ) that underlie optimal immune function. It has become clear in recent years that there is a functional interaction between the taste and immune system, and fatty acid signaling pathways serve as one focus of this overlap. Similar to taste receptor cells (TRCs), MΦ express G protein-coupled fatty acid receptors GPR120 and GPR84, and our …

It's Been Here All Along: Increasing Discomfort In Immersive Horror Puzzle Experiences Without Jump Scares, Brittany R. Porthouse

Graduate Thesis and Dissertation post-2024

This thesis seeks to utilize horror themes in a puzzle-based themed experience without the usage of jump scares. By alerting the body’s startle response once a puzzle is completed with a sudden loud noise or visuals, many horror-themed escape rooms utilize the jump scare tactic to heighten their guests’ adrenaline. While this technique is often effective in eliciting a reaction from participants, the effects are temporary– and sometimes hinder participants’ desire to fully interact with the environment. By primarily using the experience’s narrative and environment to illicit a fear response in guests, as opposed to using the consequences of their …
