Comparing Inter-Rater Reliability For Two Coding Methodologies In Meta-Analysis Data Extraction, Christine D. Destefano

Graduate Thesis and Dissertation post-2024

Meta-analyses are critical tools for evidence-based policymaking, but their validity depends heavily on accurate data extraction from primary studies. While previous research has focused on procedural aspects of coding and reliability of effect size extraction, there remains a significant gap in understanding how to improve inter-rater reliability (IRR) for moderator variables that provide crucial context for meta-analytic findings. This study compared two methodological approaches for coding moderator variables: traditional low-inference coding and a novel drill-down questioning technique adapted from database development principles. Using a comparative analysis design, two independent coders extracted data from 18 primary studies included in a published …

The Transition Of Tradition: The Modernismo Era Of Puerto Rican Postcolonial Short Fiction, Natalie Donis

Graduate Thesis and Dissertation post-2024

Modernismo, an artistic and literary cultural movement that swept across Latin America, profoundly shaped Puerto Rican short fiction by introducing innovative narrative techniques before the novel gained prominence on the island. Emerging during the sociopolitical upheaval following the Spanish American War and Puerto Rico's annexation by the United States, modernismo responded to both European artistic trends and the cultural tensions of colonial transition. In my research, in Puerto Rico, Moderismo emerged in the short story before the novel. This research examines how Puerto Rican short stories by José Luis González and Emilio Díaz Valcárcel, from this era, grapple with themes …

Positivity And Invariance: From Radial Basis Functions To Graph Signal Spaces, Seok-Young Chung

Graduate Thesis and Dissertation post-2024

This dissertation investigates the positivity problem and zero localization of special functions or integral transforms, with particular emphasis on their implications in analysis, approximation theory, and signal processing. The first half centers on the characterization of positive definite radial functions via Hankel transforms involving Bessel functions. Motivated by classical results such as Bochner's theorem and Schoenberg’s work, we examine analytic conditions under which these transforms remain nonnegative, thereby ensuring the positive definiteness of radial basis functions (RBFs). We then explore the transition beyond positivity by focusing on the reality of zeros in Hankel (or Fourier) transforms. This leads to two …

Hetero-Cisgender Rituals: The Oppression Of Sexual- And Gender-Minoritized People, Bertha A. Ben Khallouq

Graduate Thesis and Dissertation post-2024

Among the groups that experience health inequalities in the United States, sexual- and gender-minoritized people figure prominently. Medical practitioners are tasked with alleviating these health inequalities, and it has been suggested that through the education of new physicians, we can decrease these inequalities. This perspective, however, neglects that medical students are social actors and their socialization begins long before medical school. In the present study, I develop a framework for understanding hetero-cisgender rituals that medical students experience and participate in before starting their medical training. I answer three research questions: (1) To what extent do medical students witness hetero-cisgender rituals? …

Parents’ Adverse Childhood Experiences And Young Children’S Behavior Problems: Examining Protective Moderating And Mediating Factors, Kaitlyn M. Daleandro

Graduate Thesis and Dissertation post-2024

Adverse childhood experiences (ACEs) are childhood exposures to abuse, neglect, and household dysfunction. ACEs have been linked to a cumulative negative impact on later adult physical and psychological well-being. Parents who carry ACEs often have difficulties in parenting, which have, in turn, been linked to young children’s internalizing and externalizing behavior problems. Nonetheless, some parents who carry ACEs develop positive parenting strategies. Very little is known about how such outcomes occur. A growing area of research concerns protective and compensatory experiences (PACEs) that buffer against the negative consequences of ACEs. PACEs may improve deficits in cognitive, emotional, and neurobiological systems …

Beam-Clip: Multimodal Alignment For Mmwave Beam Pattern Learning, Andrew P. El Kommos

Graduate Thesis and Dissertation post-2024

This thesis presents a novel approach to beam prediction in wireless communication systems using a multimodal masked CLIP (Contrastive Language-Image Pre-training). We introduce a two-phase training methodology that first aligns representations across multiple sensor modalities—GPS, Radar, LiDAR, and RGB images—through masked contrastive learning, followed by task-specific fine-tuning for channel power reconstruction. Our approach adapts CLIP’s pre-training strategy to the domain of wireless signal modeling, enabling the model to learn rich, transferable features that capture the spatial and contextual dependencies of the beam distribution. Notably, the pre-training stage provides a substantial boost to overall performance, significantly improving the model's ability to …

A Scoping Review Of Population Diversity In The Common Genomic Aberrations Of Clear Cell Renal Cell Carcinoma, Sean S. Kumar, Ninad Khandekar, Komal Dani, Saina R. Bhatt, Vinay Duddalwar, Anishka D' Souza

Department of Medicine Faculty Publications

Introduction: Previous literature has shown that clear cell renal cell carcinoma (ccRCC) is becoming a more prevalent diagnosis and that the incidence and mortality differ both regionally and racially. While the molecular profiles for ccRCC are studied regionally through biopsy and sequencing techniques, the genomic landscape and ccRCC diversity data are not well studied. We conducted a review of the known genomic data on 6 of the most clinically relevant DNA biomarkers in ccRCC: von Hippel-Lindau (vHL), Polybromo-1 (PBRM1), Breast Cancer Gene 1-Associated Protein 1 (BAP1), Histone-Lysine N-Methyltransferase Domain-Containing 2 (SETD2), Mammalian Target of Rapamycin (mTOR), and Lysine-Specific Demethylase 5C …

Oral Microbiome And Inflammatory Bowel Disease: New Understanding And Call To Action, Michael Saadeh, Sydney Donohue, Shaina Ailawadi, Gordon Hong, David A. Johnson

Department of Medicine Faculty Publications

The oral microbiome is the second largest microbial community in the human body after the gut microbiome. It includes an array of fungi, bacteria, amoebae, flagellates, archaea, and viruses, all of which are potential pathogens. This microbiome can act as a facilitator not only for protection but also for aggravation when dysbiosis occurs. Although conventional thought is this is primarily in terms of oral health issues, such as dental caries and gingival disease. The systemic effects of the oral microbiome however, are relevant to both gastrointestinal (GI) disease and non-GI disease. These systemic risks occur for several reasons, including upregulation …
