Enhancing Bay Scallop Monitoring Using Machine Learning And Semantic Segmentation With Benthic Visual Imagery, Waheed Odubayo

Open Access Master's Theses

Effective monitoring of benthic ecosystems requires scalable approaches capable of simultaneously identifying key species and quantifying habitat composition. In Narragansett Bay Rhode Island, bay scallops, Argopecten irradians, serve as important ecological indicators, yet traditional survey methods remain labor-intensive and spatially limited. This study presents an automated deep learning framework for scallop detection and habitat segmentation using underwater benthic imagery.

The proposed system combines three components: (1) YOLO based object detection for identifying live scallops, (2) U-Net semantic segmentation for quantifying benthic habitat classes (eelgrass and sand/silt), and (3) a geospatial contrastive learning framework (GeoCLR) to leverage spatial continuity in …

Investigating Netarts Bay, Oregon Coastal Landscape Change From Tectonic Subsidence Through Isotopic, Stratigraphic Records And Quantifying Dune Influence On Salt Marsh Morphodynamics, Emily Hall

Open Access Master's Theses

Coastal salt marshes on tectonically active margins face dual pressures from episodic seismic events and anthropogenic modifications. This study investigated how the 1700 CE Cascadia Subduction Zone earthquake and the 1900 CE introduction of invasive dune grass influenced back-barrier salt marsh morphodynamics at Netarts Bay, Oregon. It was hypothesized that (1) salt marsh habitats and elevation transitions would be detectable in geochemical proxies preserved in stratigraphy, (2) modern dune stabilization significantly limits mineral sediment delivery to the salt marsh, and (3) this reduction would be preserved in the stratigraphic record. Stratigraphic and isotopic analyses of sediment cores incorporating CT scans, …

Using A Novel Approach To Measure Phonological Working Memory In Parents Of Children With Autism: A Nonword Repetition Study, Giavanna Galati

Open Access Master's Theses

Background: The etiology of Autism Spectrum Disorder (ASD) has been a topic of debate among researchers for many years. Fundamental evidence, especially from twin studies, supports a strong genetic component. This evidence now prompts us to examine first-degree relatives of individuals with ASD. Many first-degree relatives, especially siblings and parents, often exhibit subclinical traits of autism, referred to as the Broad Autism Phenotype (BAP). Several researchers have investigated personality traits and pragmatic language skills; however, few researchers have investigated core language skills, particularly phonological working memory (PWM), in parents of children with ASD (pASD). Purpose: Past research has …

Amino Acid Isotope Dynamics And Associated Ecological Metrics Across Accretionary Tissues Of Marine Fishes, Sofia Piccone

Open Access Master's Theses

Compound-specific isotope analysis of amino acids (CSIA-AA) applied to the organic growth layers of accretionary fish tissues, including eye lenses, otoliths, and scales, has made it possible to reconstruct histories of fish physiology, ecology, and environmental conditions. Yet it remains uncertain whether amino acid isotope values, and the ecological information they contain, are conserved across these archival tissues or if differences in tissue composition, growth, protein structure, and metabolic routing produce tissue-specific offsets that alter inferred carbon sources, d¹⁵N_Baseline, and trophic position. We tested this question with individually paired CSIA-AA of eye lenses, otoliths, and scales …

Evolution Of A Managed Flood-Tide Delta And Barrier-Beach System, Charlestown, Rhode Island, Zachary Justin Levitan

Parental Psychological Distress And Perceived Child Externalizing Behaviors: Examining Mediators And Bidirectional Effects, Abigail J. Anderson, Christina M. Rodriguez, James M. Henson

Psychology Faculty Publications

Parental psychological distress is a commonly examined risk factor for the emergence of child problem behaviors, but the factors that contribute to that relationship—such as limited parental resources like greater social support and coping skills—have not been adequately explored, particularly with attention to potential bidirectional relations that incorporate child evocative effects. The current longitudinal study examined maternal and paternal psychological distress in relation to perceived child externalizing behaviors, considering parental resources as mediators within a bidirectional model. The sample included a racially and socioeconomically diverse group of 201 primiparous mothers and 151 fathers. Mothers and fathers reported their current psychological …

Establishing Hierarchical Classification Responding: Directly Trained And Emergent Responses, George H. Noell, Kristin A. Gansle, Hannah M. Sliman, Danielle M. De Lucia

Psychology Faculty Publications

Hierarchical classification responding (HCR) describes a collection of responses that require discrimination of logical relationships between stimuli based on their position in a categorical hierarchy. This study established HCR for a new hierarchy in young children through discrete trial instruction. Participants selected pictures corresponding to different hierarchical levels of categorization. We tested for the emergence of naming that matched the level of hierarchy presented, transformation of function, and class inclusion responding for the trained and novel stimuli. Correct responding to the target hierarchy was established and resulted in the emergence of class naming and transformation of function without direct instruction. …

Examining The Factor Structure And Subgroup Invariance Of The Deliberate Denial Of Disordered Eating Behaviors Scale, Lindsay Howard, Sage Hawn, Kayla D. Pitchford, Riley Mcgrath, Aubri Farniok, Arturo Sesma, Kristin E. Heron

Psychology Faculty Publications

The denial, concealment, or omission of disordered eating behaviors has received limited attention in the eating disorder literature, partly due to the lack of reliable and valid measures. This study re-examined the factor structure of the Denial of Disordered Eating Behaviors Scale (DDEBS-12) and tested measurement invariance across gender identity, racial identity, and levels of disordered eating in a non-clinical undergraduate sample (N = 3285). Confirmatory factor analyses did not support the original unidimensional structure. Instead, a seven-item model assessing denial of dietary restriction demonstrated the best fit and was renamed the DDEBS-restriction. The revised scale showed good internal consistency …

Professional Identity Development Among Nursing Students: The Impact Of Structured Reflective Practice, Abdelmonim El Fadely, Kamal Takhdat, Charaf-Eddine Ahraiba, Rahma Bouali, Sabah Selmaoui, Boujemaa Agorram

Health Professions Education

Purpose This study aimed to assess the impact of a structured reflective practice intervention on the development of professional identity among nursing students. Method A mixed-methods design was adopted. The intervention, based on guided reflective practice, was implemented with a voluntary sample of 58 participants. The evaluation relied on a quasi-experimental quantitative approach using the Macleod Clark Professional Identity Scale, with a comparison group and both pre-test and post-test measurements. A qualitative component was also included to explore the dimensions of the studied concept in greater depth. Results Quantitative findings showed a statistically significant difference between the post-test means (p < 0.001), indicating that the reflective practice intervention had a positive effect on the experimental group compared to the control group. The qualitative results further illuminated students’ reflections, which were organized into ten themes corresponding to the study’s conceptual framework: professional knowledge and skills, values and ethics, the nursing role, leadership, professional self-image, social image of the profession, sense of belonging, identification with role models, theory–practice integration, and career choice. These dimensions provided a comprehensive and nuanced understanding of professional identity, capturing the complexity of the concept. Conclusion These results support the integration of reflective practice as a pedagogical approach to fostering the construction and development of a positive professional identity. Professional identity, as a rich and multidimensional concept, goes beyond the process of professionalization—it represents its ultimate achievement.

Copyright Protection Or Media Suppression? The Digital Millennium Copyright Act's Impact On News Media And Journalism, Alenis Olivera

FIU Law Review

When copyright law collides with press freedom, which one survives the takedown? The Digital Millennium Copyright Act (DMCA) was once hailed as a necessary adaptation to copyright protection issues in the digital age. But now, nearly three decades since its incorporation into the Copyright Act, the DMCA has continued to cast a shadow over the journalism industry. The DMCA’s notice-and-takedown system, originally designed to protect copyright owners by allowing for quick removal of infringing content, has become a mechanism that risks suppressing lawful reporting and undermines the First Amendment’s guarantee of a free press. This Comment will explore how the …

Private Equity In Healthcare: The Case For Stricter Regulations, Ryan Scivally

FIU Law Review

Private equity has become an increasingly influential force in American healthcare. Hundreds of billions of dollars have flown into healthcare acquisitions over the last decade, and a growing share of physician practices and health services are coming under investor control. This Comment argues that the current regulatory framework has not kept pace with that expansion. Existing federal tools, primarily antitrust and fraud enforcement, leave most transactions unreviewed because many deals fall below reporting thresholds. At the state level, doctrines such as the corporate practice of medicine are unevenly enforced and often avoided through management services’ organization structures. These structures preserve …

Owning Trading Opportunities, Kevin Douglas

FIU Law Review

Owning Trading Opportunities identifies the doctrines and policy rationales used to protect property rights in corporate opportunities. It then explores adopting these doctrines and rationales to reform the notions of "fairness," "public interest," "investor protection," "market confidence," and "economic efficiency" driving the regulation of insider trading.

This approach yields several benefits. First, it shows that a policy commitment to equal trading opportunities for all investors is the functional equivalent of a commitment to fostering equal access to information for all investors. The U.S. Supreme Court attempted to reject the latter but failed by embracing the former.

Second, corporate opportunity cases …

Forum Selling As A Threat To The Rule Of Law, Brian Iverson

FIU Law Review

Forum shopping has long been a feature of federal litigation, but recent years have brought a more troubling dynamic in which federal courts compete for cases by “forum selling.” Judges engage in forum selling by adopting plaintiff-friendly procedures, reliably issuing plaintiff-leaning decisions, and publicly soliciting certain types of cases. These practices transform localized procedural discretion into a structural risk for the federal judicial system.

This Article makes two novel contributions to the federal forum-selling literature. First, it expands the discussion beyond bankruptcy and patent practice to examine ideological influences. Drawing on empirical scholarship and illustrative judicial profiles, the Article identifies …

CONRAD Publications

Innate immunity predictors of HIV-1 risk and pathogenesis vary with reproductive hormones, pregnancy, and lactation, yet the underlying mechanisms remain unclear. We hypothesized that pregnancy-associated physiological adaptations alter systemic microRNA (miRNA) expression, thereby regulating immunity, pathogenesis and susceptibility to infection. We analyzed 174 serum samples from 88 participants in a longitudinal cohort from Uganda and Zimbabwe across pre-pregnancy (PP), pregnancy (P), and postpartum breastfeeding (BF). Cell-free peripheral blood miRNAs (n = 2083) were profiled using HTG EdgeSeq. Pregnancy-specific miRNAs were identified by intersecting differentially expressed (DE) miRNAs from P vs. PP and P vs. BF comparisons. miRNA targets and pathways …

Cylinder Wake Stability Effects Of Passive Forebody Modification And Active Harmonic Actuation, Matt Duran

Graduate Studies Theses and Dissertations 2026

This dissertation investigates the manipulation of global and three-dimensional instabilities in the wake of a circular cylinder through two separate flow control methods. This study first focuses on the influence of attached leading edge forebodies as a form of passive flow control designed to introduce upstream streamline curvature, where the curvature takes the form of a concave and convex case. We demonstrate that for both cases this induced curvature significantly modifies the primary instability, which suppresses periodic vortex shedding (Von Kármán vortex street). We found an increase in critical Reynolds number of 56.6 and 60.1 for the concave and convex …
