Tail-Imbalance Diffusion Equalizer For Class-Balanced Generation, Chinmay Dhanraj Nehate

Graduate Thesis and Dissertation post-2024

Real-world image corpora are often imbalanced. On long-tailed datasets, the head class can outnumber the tail by a large margin, and a vanilla diffusion probabilistic model (DPM) consequently loses fidelity and diversity on rare categories, undermining controllable generation. To address this gap, we present Tail Imbalance Diffusion Equalizer (TIDE), a training framework that restores class balance without discarding data or adding extra training stages. Our contribution is threefold: (i) score field rebalancing, where we embed class-prior knowledge into a mixing matrix that routes gradients toward minority classes, with this class-prior knowledge consisting of the empirical label frequencies in the training …

A Variable Resistance Suit (Vars) And An Extendable Prosthetic Arm (Expa) For Physical Rehabilitation And Assistance, Ibrahim F. Kadhim

Graduate Thesis and Dissertation post-2024

This dissertation investigates the structures and mechanisms underpinning the latent space representations that emerge within Generative Pretrained Transformer (GPT) models. Addressing the broader goal of enhancing AI trustworthiness through transparency, accountability, and controllability, we focus on techniques to understand, quantify, and manipulate these latent space representations. Through a series of analyses, we examine several chess-playing GPT models as controlled testbeds, leveraging their structured decision space to explore emergent representations and decision-making processes.

Key contributions include a mechanistic analysis of the attention heads and latent representations, the development of novel metrics for evaluating intervention outcomes, and the application of linear probe …

Cnn's Portrayal Of The Build Back Better Act, Alexander J. Toj-Moody

Graduate Thesis and Dissertation post-2024

The purpose of this study is to investigate the effect of CNNs representation of the Build Back Better Act and its failure to pass senate reconciliation during the fall of 2021. The Build Back Better Act was a piece of legislation that intended to fix America’s social infrastructure, such as investing in education, the environment, expanded healthcare, etc. The bill ultimately failed and its replacement, the Inflation Reduction Act of 2022, cut numerous benefits that were proposed within the Build Back Better Act. Examination of broadcast transcripts during this period of time find an operationally liberal framing, though the focus …

Sex Estimation Using Linear And Geometric Morphometric Analyses Of The Adult Human Talus, Melissa N. Marks

Graduate Thesis and Dissertation post-2024

Estimating biological sex is an essential first step when analyzing human remains in both forensic and archaeological contexts. While the pelvis and skull are traditionally used for this purpose, they are not always present or sufficiently preserved to permit analysis. The talus is sexually dimorphic and can yield highly accurate sex estimates, making it a promising alternative skeletal element for sex estimation. As there is currently no accepted protocol for sex estimation using the talus, the present study attempts to replicate and validate existing methods using linear and three-dimensional landmark data, while comparing data from ancient Maya (n=16), ancient Egyptian …

Differential Interferon Synthesis And Signaling Between Parainfluenza Virus Acute And Persistently Infected Cells, Vonisha Kaigler

Graduate Thesis and Dissertation post-2024

RNA virus infections can transition from an initial acute infection to a prolonged or persistent infection, in which infected cells survive and continue to produce progeny virus. This presents a major clinical problem as persistently infected (PI) cells extend viral shedding, maintain inflammation, and provide potential sources for new viral variants. The RNA virus, Parainfluenza virus 5 (PIV5), with mutations in the P/V gene region (P/V mutant) is a strong inducer of antiviral responses. Interestingly, over time, there is an emergence of cells that survive as P/V mutant PI cells. Given that changes in innate immune signaling pathways can occur …

'How To Mother': Televisual Reimaginings Of Black Matriarchy In The Real Housewives Of Potomac, Kalijah Rahming

Graduate Thesis and Dissertation post-2024

Since the initial launch of The Real Housewives of Orange County in 2006, Bravo’s The Real Housewives franchise has soared to previously unimaginable heights. With 11 American installments, 30 international adaptations, and 25 current spin-offs, it is clear that even viewers who are relatively unfamiliar with The Real Housewives franchise may find themselves inadvertently swept up in their world due to the popularization of their catchphrases and gifs on social media platforms like Instagram, Twitter, and Facebook. In addition to carefully shaping popular culture, members of this franchise have even altered the conditions of the entertainment industry’s practices for the …

The Path Of Peace: Non-Violent Methods Of Play In Indie Video Game History, Ryu R. Yamamoto

Graduate Thesis and Dissertation post-2024

This research project investigates the cultural and historical significance of independently published Japanese bullet-hell/danmaku games from the 2000s and 2010s. This project highlights gaps in current game histories, particularly surrounding the influence of these games on heralded contemporary titles like Undertale (2015). The significance of independently published “doujin” Japanese digital media, notably the Touhou Project series, is often overlooked in American game studies contexts. Examining these underexplored games aims to enrich the understanding of cultural-historical games research, particularly in positioning lesser-known and lower-budget games, and contribute to the broader discourse on cross-cultural interactions within the gaming community. Comparative analyses of …

A Forgotten Kairos: Rhetorical Memory In 16th Century Europe, Phillip Martin

Graduate Thesis and Dissertation post-2024

In 16^th century Europe the nearly 2000-year-old discipline of rhetoric, still a pillar of education, underwent significant change. One of the more curious changes occurred in rhetoric’s subdivision known as memory, memoria, that is, memory’s “artificial” cultivation. During the 16^th century rhetorical memory was paradoxically both maximized and marginalized as a discipline. And by the early 17^th century memoria was all but extinct as a branch of rhetoric. The causal mechanisms of this transformation remain underexamined, particularly by rhetoric and composition scholars, and most explanations remain unclear and uncompelling. Accordingly, this thesis attempts a new approach …

The Impact Of Alternatives To Incarceration And The Motherhood Identity On Mothers And Their Children: A Qualitative Study, Chloe Blau

Seton Hall University Dissertations and Theses (ETDs)

The U.S. prison system population increasingly includes women, a significant proportion of whom are mothers, often incarcerated for non-violent crimes. Some research suggests that alternative to incarceration (ATI) programs can help these women to continue supporting their children while serving their sentences and receiving services that may decrease recidivism. However, few studies have explored the lived experiences of women in these programs. This dissertation investigates the impact of participating in ATI programs on mothers and their relationship to their motherhood identity, their ability to mother, and their relationship with their children. Using a qualitative approach to better understand how women …

The Effectiveness Of Pre-Packaged Literacy Curriculum: A Document Analysis Of The Culturally Responsive Tenets In Pre-Packaged Literacy Curriculum, Grace Ghazzawi

Seton Hall University Dissertations and Theses (ETDs)

The introduction of the Common Core State Standards in 2010 sought to standardize educational expectations across the U.S., aiming to promote equity by ensuring all students received a high-quality education. However, educational disparities persist, particularly for historically marginalized students, leading to a continued achievement gap in literacy, especially among low-income students of color. While pre-packaged curricula have emerged as tools to align instruction with the rigor of the Common Core State Standards, their effectiveness in addressing the diverse needs of students from marginalized backgrounds remains uncertain. This study explores the intersection of pre-packaged literacy curricula and Culturally Responsive Teaching (CRT) …

Seton Hall University Dissertations and Theses (ETDs)

The current study was conducted to investigate individuals’ perceptions of ABA as influenced by social media. A survey that included videos selected from TikTok, a social media platform, was provided to parents/stakeholders of children with Autism Spectrum Disorder (ASD), practitioners/employees of ABA (BCBAs, RBTs, etc.), and teachers. Participants were acquired using recruitment posts on TikTok and Facebook, through email, and by word-of-mouth/referral. 58 participants in total fully completed the survey. The survey was conducted using Qualtrics and included 32 questions and eight TikTok videos. The results showed that parents/stakeholders’, practitioners’, and teachers’ opinions of ABA were not influenced by the …

A Thematic Analysis Of The Perceived Impact Of Nil Policy On Athletic Identity, Career Maturity, And Black Male Student-Athletes’ Experience Of Transitioning Away From Football, Jesse Merise

Seton Hall University Dissertations and Theses (ETDs)

In 2007 the NCAA launched the widely recognized slogan, “There are over 380,000 student-athletes, and most of us will go pro in something other than sports.” Today, that figure has risen to over 540,000 and continues grow. Among them, Black male student-athletes (BMSAs) comprise 40% of collegiate football participation across all three divisions, a notable increase from 36% in 2012. Since only a small percentage of college football players go on to play professionally, it means that a large number of Black student-athletes will eventually have to leave sports and pursue other career paths.

This study examined the perceived impact …

The Benefits Of Establishing Attending Behavior Prior To The Discriminative Stimulus During Discrete-Trial Instruction: A Systematic Review, Ruben S. Pereira

Seton Hall University Dissertations and Theses (ETDs)

Discrete trial instruction (DTI) is one of the most effective and commonly used instructional strategies for teaching individuals with autism. Researchers and professionals have informally promoted the importance of establishing attending behavior prior to initiating discrete trials. However, some researchers have reported a lack of literature analyzing the effects of establishing attending behavior, prior to instruction, on skill acquisition. Therefore, the benefits of establishing attending as part of DTI remain unknown. The goal of the current thesis was to conduct a systematic review using PRISMA guidelines to search for published studies where attending behavior was a primary independent variable within …

Roles Of Ifn-Alpha/Beta And Ifn-Gamma In Enhancing And Inhibiting Nk Cell Mediated Killing Of Oncolytic Virus Infected Tumor Cells, Elisabeth M. Shiffer

Graduate Thesis and Dissertation post-2024

Type I interferon (IFN-I) and interferon-gamma (IFN-γ) are potent cytokines that can be produced by virus-infected cells and Natural Killer (NK) cells, respectively. The relative roles of these two IFNs in promoting NK cell killing of tumor cells was tested in the context of combining particle-based ex vivo expanded PM21-NK cells and infection with oncolytic Parainfluenza virus 5 (PIV5). Activated NK cells produce IFN-γ, which can upregulate NK cell inhibitory ligands on tumor cells and reduce NK cell killing. We hypothesized that resistance of tumor cells to NK cell killing could be overcome by expression of the PIV5 V protein, …

A Community-Based Wellness Program To Increase Exercise Adherence For Menopausal And Postmenopausal Women: A Mixed-Methods Pilot Study, Kristin M. Badillo

Graduate Thesis and Dissertation post-2024

Evidence exists that long-term commitment to an exercise routine is beneficial. Contrarily, there is a notable lack in exercise adherence among menopausal and postmenopausal women. Though research has thoroughly examined the reasons why menopausal and postmenopausal women may not be committed to an exercise routine, it remains unclear what motivates those who are adherent. This pilot study employed a mixed-methods design through administering surveys and conducting in-person focus group interviews. Additionally, an 8-week buddy system was implemented to assess the role of social support and its effect on exercise adherence. For quantitative data collection, a total of 7 participants enrolled …

The model combined teacher feedback and modeling, structured reflection tasks (including AI‑assisted reflection), AI assisted editing, AI-assisted literature searches, and counterargument support using restricted chatbots. During the nine week period, responsibility for feedback moved from teacher and AI supported scaffolding to student driven writing practice and revision. Data collection focus on four advanced high school students at a Florida public high school, including multiple drafts, GAI input and output logs, reflections, and pre‑ and post‑unit semi‑structured …

Predicting Past And Future Anthropogenic Global Harvest And Land Use, Michelle Bardales Cruz

Graduate Thesis and Dissertation post-2024

Anthropogenic appropriation of natural lands has long sustained human populations and activities. Human use of the environment has resulted in the degradation of green spaces and depletion of natural, particularly plant-based, resources. Human appropriation of net primary production (HANPP) is a globally available, spatially explicit measure of this human-driven extraction and diversion of plant biomass through harvesting (HANPP_harv) and land use change (HANPP_luc). Models for HANPP have been limited temporally (e.g., a year) or in terms of complexity (e.g., one predictor). In this study, I predict HANPP_harv and HANPP_luc from 1960 to 2010 at …

Additionally, this study attempted to identify any differences in career transition expectations between student-athletes and athlete-students. Thirteen NCAA athletes from various universities across the United States were included. With the use of one-on-one semi structured interviews, five themes emerged. The themes that emerged were 1) Both types of athletes attend college for different reasons. 2) Differences in level of commitment. 3) Both types of athletes strive for academic success. 4) Different expectations …

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 …

Integrating Education For Sustainable Development Into Elementary Curriculum Through Transdisciplinary Learning: A Case Study Of Teachers At Designated Green Schools, Amanda Ferguson

Graduate Thesis and Dissertation post-2024

The rising number of sustainability-focused jobs in the United States has underscored the need for greater exposure to Education for Sustainable Development in early education. While higher education and secondary schools offer courses on sustainability and the environment, elementary students have limited opportunities to engage with these topics. This embedded multiple-case study examined the role of Education for Sustainable Development in elementary classrooms, specifically through transdisciplinary lessons. The research was guided by the question: How do elementary teachers in county-designated Green Schools in a Florida district use transdisciplinary lessons to teach sustainability within their existing curriculum?

Using the theoretical framework …

A Case Study Of Grades 3-4 English Language Arts Teachers' Interpretations Of Educational Policy And Their Pedagogical Choices In Literacy Instruction, Priscilla Develder

Graduate Thesis and Dissertation post-2024

The purpose of this qualitative case study was to explore how elementary school teachers in a Florida public school district made sense of Florida’s House Bill 1467: K-12 Education (HB 1467) and how their interpretations shaped their reading and writing pedagogy. Guided by Karl Weick’s (1995) Sensemaking Theory as a theoretical lens for understanding these interpretations, the study examined how teachers navigated the complexities of policy implementation within the context of their daily classroom experiences. Participants included six third- and fourth-grade English Language Arts (ELA) teachers from four elementary schools within a Florida public school district. Data was collected …

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 …

Examining The Relationship Between Volunteerism And Revenue Streams In Youth-Centered Nonprofit Organizations: An Analysis Of Fundraising Revenue, Program Service Revenue, And Government Grants, Stephanie Aguguo-Orelus

Graduate Thesis and Dissertation post-2024

This study examined the relationship between volunteerism and revenue streams in youth-centered nonprofit organizations (NPOs) in the United States. Utilizing financial data from IRS Form 990 filings spanning 2014 to 2023, the research analyzes how the number of annual volunteers impacts three primary revenue sources: donations, program service revenue, and government grants. Fixed-effects regression models are employed to evaluate these relationships across the full study period and in pre- and post-COVID-19 subsamples. The study also investigates the association between volunteerism and revenue diversification using the Herfindahl-Hirschman Index (HHI). Findings reveal a positive and statistically significant relationship between volunteer involvement and …

Decreasing Administrative Burdens For Promoting Social Equity: Three Essays On Innvations In Public Service Provision, Kyungmin Lee

Graduate Thesis and Dissertation post-2024

This dissertation investigates three aspects of administrative burdens in public service delivery and explores how these burdens—which often discourage eligible individuals from accessing needed services—relate to individuals' perceptions of and behaviors toward those burdens and ultimately to user outcomes. The first essay examines whether a shift from in-person to virtual service modalities imposes additional administrative burden—digital administrative burden—for service users. Using the secondary data from the 2022 “Survey of Citizens’ Perceptions of Public Administration” conducted in South Korea, the study applies Coarsened Exact Matching (CEM) to assess the relationship between service modality and digital administrative burden. The findings suggest no …

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 …

Emojis As Text Technology: Between Visual Paradigm And Cultural Revolution, Hanan Hafiz

Graduate Thesis and Dissertation post-2024

Emojis, as a broader communication phenomenon, have gained widespread usage, significant adaptation, and considerable academic attention due to their role in providing semiotic cues and online gestures within computer-mediated communication. This study aims to trace their development and evolution using the text technologies framework. This approach examines the systematic use of emojis, with particular emphasis on their extensive evolution by historically contextualizing their usage, trends, and cultural interactions. Anchored in this conceptual approach, the study draws on the taxonomy of text technology developed by Treharne and Willan, analyzing the evolution of emojis through four key dimensions: intentionality, materiality, functionality, and …
