Instance-Level Video Depth In Groups Beyond Occlusions, Yuan Liang, Yang Zhou, Ziming Sun, Tianyi Xiang, Guiqing Li, Shengfeng He

Research Collection School Of Computing and Information Systems

Depth estimation in dynamic, multi-object scenes remains a major challenge, especially under severe occlusions. Existing monocular models, including foundation models, struggle with instance-wise depth consistency due to their reliance on global regression. We tackle this problem from two key aspects: data and methodology. First, we introduce the Group Instance Depth (GID) dataset, the first large-scale video depth dataset with instance-level annotations, featuring 101,500 frames from real-world activity scenes. GID bridges the gap between synthetic and real-world depth data by providing high-fidelity depth supervision for multi-object interactions. Second, we propose InstanceDepth, the first occlusion-aware depth estimation framework for multi-object environments. Our …

An Evaluation Of Noncontingent Reinforcement And Additional Treatment Components In The Treatment Of Stereotypic Behavior, Stephanie Nicole Brand

Theses and Dissertations

Individuals with autism often engage in stereotypic behavior that competes with learning and social skills. Behavior analytic treatment may be implemented to reduce stereotypy. Noncontingent reinforcement (NCR) is one treatment that is often effective to reduce stereotypy. However, literature suggests that the use of NCR is contraindicated in some circumstances, as it may compete with the acquisition of new skills or may increase subsequent persistence of stereotypy. This research was designed to expand our knowledge of potential limitations of NCR when combined with other treatments. Study one examined persistence of stereotypy following treatment with NCR with and without response blocking. …

Benthic Infaunal Responses To Shoreline Restoration, Jessica Lauren Cline

Theses and Dissertations

In the age of increasing urban coastal sprawl, natural shorelines are being replaced by hard armoring structures, which result in the loss of valuable ecosystem services. Hybrid living shorelines, areas that include limited and less intensive armoring strategies paired with the integration of plants and other natural materials, present an opportunity to marry the need for more aggressive stabilization with the continued preservation of ecosystem functions and biological communities. This project uses benthic infauna to evaluate the success of a living shoreline installation in Palm Bay, Florida. The deployment features experimental treatments of breakwaters and red mangroves to explore how …

Comparative Assessment Of Lower Limb Neuromusculoskeletal Activation And Joint Kinematics In Normal And Impaired Gait, Jack Ryan Schule

Theses and Dissertations

This thesis evaluates whether accessible and affordable technologies can provide clinically significant, quantifiable gait analysis comparable to traditional marker-based motion capture systems. Modern high-end systems offer excellent accuracy but remain financially and logistically inaccessible to many clinicians and researchers. To address this gap, a framework was developed using markerless pose estimation using the model, MediaPipe, inertial measurement units (IMUs) processed through an Extended Kalman Filter (EKF), and surface electromyography (sEMG) to measure joint kinematics and neuromuscular activity during gait. An experiment was performed where data was collected from participants with both normal gait and pathologies including: Osgood–Schlatter disease, Plica Band …

Conflict Management: Values-Based Training Effects On Shifts In Strategy Preference Among Formerly Incarcerated Individuals, Candace Renae Fay

Theses and Dissertations

Problem-solving refers to a behavior evoked by a problem in which the behaver manipulates, supplements, and consequently, generates discriminative stimuli (SD) that they subsequently respond to (Donahoe & Palmer, 2004; Skinner, 1957, 1968). The use of problem-solving when faced with interpersonal conflict reflects pro-social behavior patterns, while providing a learning opportunity for identifying relevant variables and contingencies, and possible reductions of extended conflict or escalation in anti-social behavior patterns. Patterns of preference can be identified following multiple opportunities, given an array of options, resulting in consistency of choice responses (Martin, 2006). When less prosocial (avoiding, yielding), or antisocial (forcing) conflict …

The Role Of C-X-C Chemokine Receptor Type 5 (Cxcr5) On Sex-Dependent Neurobehavioral Changes In The Sub Clinically Sensitized Individuals With Repeated Allergen Exposure, Dilini Vimarshani Ekanayake Ekanayake Mudiyanselage

Theses and Dissertations

Food allergen consumption has been suspected to influence mood and behavior in individuals who are sensitized but tolerant to the food. Using a mouse model of subclinical cow’s milk allergy (CMA), we previously showed that C57BL/6J mice sensitized to β-lactoglobulin (BLG, Bos d 5) exhibited elevated BLG-specific IgE levels even without observable allergic reactions, suggest developing immune responses towards the allergen. We also observed elevated cytokine and chemokine levels, astrogliosis and cortical demyelination along with behavioral changes such as anxiety-like and depression-like behavior after consuming a whey-containing diet for two weeks. Furthermore, we demonstrated the possible immune cell infiltration and …

Extraction Of Cellulose From Paper Towels For Sustainable Bio-Based Polyurethane Adhesives, Yashkumar J. Patel

Electronic Theses & Dissertations

The increasing consumption of paper towels generates significant waste, necessitating sustainable recycling solutions. This study investigates the extraction of cellulose from waste paper towels and its application in bio-based polyurethane (PU) adhesives. The extraction process includes alkali treatment, bleaching, and acid hydrolysis to obtain recycled cellulose (rCL). The extracted cellulose is then used in PU synthesis alongside castor oil polyol (COP) and methylene diphenyl diisocyanate (MDI), with performance compared to industrial cellulose-based PU. The obtained rCL and synthesized PU adhesives have been characterized with FT-IR spectra for structural confirmation. In addition, the synthesized PU adhesives demonstrated improved mechanical and thermal …

Naam, Amna Haider

Graduate Thesis Collection

This thesis is a collection of short stories that blends realism, speculative fiction, and South Asian folklore to examine how identity is negotiated through belief, culture, and survival across borders. The stories center characters who must continually interpret the worlds they inhabit in order to sustain self identity. Names in this collection function as sites of power and vulnerability: they are inherited, altered and concealed, shaping how characters are seen and how they see themselves. Alongside names, the supernatural and myth emerges not only as metaphors, but as lived forces, drawing from Islamic folklore and mythic traditions to articulate experiences …

Survivorship In Virginia Opossums And The Management Implications For Burmese Pythons In Key Largo, Florida, Arya J. Sanjar

Theses

This study employed a telemetry-based framework, using radio-collared Virginia opossums (Didelphis virginiana), to quantify survival patterns and estimate detection probabilities of python predation events. Between April 2022 and January 2025, 135 adult opossums were monitored using VHF collars across protected habitats within Key Largo. Annual survival was estimated using a staggered-entry Kaplan-Meier model, producing an annual survival rate of 0.17 (SE = 0.089) for females, and male survival was estimated at 0.04 (SE = 0.032) at 10 months since no male lived 10 months after collaring. Cause-specific monthly survival analyses indicated python predation peaked during the late summer months of …

The Role Of Sex And Genetic Background In Early Life Stress Effects On Locus Coeruleus Physiology And Related Cognitive And Affective Behaviors, Savannah Grace Brannan

Dissertations

Adverse Childhood Experiences (ACEs) have been associated with many neurodevelopmental and affective disorders, including attention deficit hyperactivity disorder (ADHD) and generalized anxiety disorder (GAD), with more exposures increasing negative risks. Sex and genetic background are biological variables involved in adverse psychiatric outcomes due to ACE exposure(s). Few preclinical studies have properly powered each sex to determine the interaction between sex and genetics on stress-impacting behavior, especially in early life. Females generally have an increased prevalence of stress-related psychopathologies beginning after adolescence, indicative of the adolescent time period as a female-specific sensitive period. To understand the underlying neuronal components responsible for …

Crux: Exploring Imperialism And Resistance Through Role-Playing Games, Devon Gronka

Institute for the Humanities Master's Papers, Projects, and Capstones

This is a game about power. The game is a Role-Playing Game, or RPG. As with nearly all RPGs, the game presents the players with choices about how their characters will interact with each other and with the world around them, and these interactions are woven together to more or less form a plot. However, oftentimes in life there are no good choices available, and there is no win state outside of what we might determine for ourselves.

The game is a social experiment. While playing a game, a player takes in information in a very different manner than when …

"Reeling In" The Governance Problem: How To Achieve Sustainable Fisheries On An International Scale, Louis Morais-Andrade

Brooklyn Journal of International Law

In 2025, it was estimated that over 35% of international fish stocks were overfished, risking severe depletion of high seas fisheries. In general, countries have control over fisheries within 200 nautical miles of their coastal border. Many countries have established fishery conservation laws to help prevent overfishing. Some examples of the largest domestic fishing laws are the Magnuson-Stevens Fishery Conservation and Management Act and the European Union’s Common Fishery Policy (MSA), which functions as an international policy that governs all of the United States’ fisheries and the European Union’s Common Fisheries Policy (CFP). Concurrently, the United Nations has also opened …

Context Dependent Regulation Of Dicer Function During Oocyte-To-Embryo Transition, Nick A. Newkirk

Dissertations and Theses (Open Access)

Over two decades ago, Dicer was discovered as the primary enzyme responsible for the generation of small RNAs known as the microRNAs (miRNAs) and short interfering RNAs (siRNAs). Spatiotemporal regulation of Dicer-dependent small-RNA biogenesis affects many aspects of biology, including aging, disease progression, fertility, and cancer. Interestingly, a distinct population of Dicer-dependent small RNAs, known as the endogenous siRNAs (endo-siRNAs), are uniquely abundant in the germ cells and gametes, and are critical for normal fertility. Despite their function regulating new life, the mechanisms controlling their biogenesis and subsequent germ cell functions remain poorly defined. Work to parse these mechanisms in …

Capsinoids, Non-Pungent Trpv1 Agonists, Induce A Mild Hypothermia That Provides Short- And Long-Term Neuroprotection After Ischemic Stroke, Alexander Andersohn, Alexander Andersohn

Dissertations and Theses (Open Access)

Therapeutic hypothermia (TH) has demonstrated neuroprotection in instances of cardiac arrest and neonatal hypoxia/ischemia but faces different challenges in application to stroke due to the activation of cold defense mechanisms in conscious patients. This dissertation examines the efficacy and specificity of capsinoids (a purified mixture of capsiate and dihydrocapsiate) to induce a sustained mild hypothermia in conscious mice that is neuroprotective after stroke. Capsinoids function as TRPV1 agonists. However, unlike capsaicin, capsinoids are vulnerable to esterase-mediated breakdown, thus significantly restricting their action to the site of delivery. We showed that capsinoids delivered intraperitoneally (IP) to mice induced a TRPV1-dependent drop …

Neural Dynamics Supporting Flexible Cognition, Meredith J. Mccarty

Dissertations and Theses (Open Access)

Flexible cognition enables humans to adapt their behavior to changing circumstances by prioritizing relevant information and filtering out distractions. This process is thought to be supported by the integration of ongoing behavioral goals with incoming sensory information, but how this integration is realized in the human brain remains unclear. It is unknown how high-order sensory cortices can balance specialized processing with flexible integration of changing behavioral goals. In the following investigations, we use intracranial EEG (iEEG) recordings in humans to study the neural dynamics of flexible cognition during high-order sensory processing. First, we validated assumptions about the locality of iEEG …

A Mixed Methods Study Of The Weather And Climate Science Curriculum Pilot In South Carolina K-12 Schools, 4-H, And Agricultural Education Programs, Emily B. Hood

All Dissertations

Weather and climate science topics in K-12 education are more important now than ever due to extreme weather and climate events happening worldwide. Most U.S. science teachers included climate science in their courses, but they may not have a sufficient background in the topic which can hinder their efforts, or there is no explicit curriculum for the teacher to utilize. Research indicates that there is a need for innovation in the curriculum to help prepare children to become the next generation of leaders and address complex problems, such as issues related to weather and climate science. There are a few …

This explanatory sequential mixed-methods study examines how South Carolina 4-H agent/educators perceive and adopt the 4-H Thriving Model following mandatory statewide training. The study investigates the roles of professional identity, change readiness, and organizational factors in shaping innovation adoption decisions among Extension professionals who work with considerable autonomy within diverse community contexts.

The 4-H Thriving Model represents a comprehensive theory of change that connects program practices to the developmental processes that influence youth outcomes (Arnold and Gagnon, 2019). The model …

Examining The Roles Of Embodiment And Theory Of Mind In Shaping User Perceptions Of Llm-Driven Conversational Agents, Elizabeth A. Schlesener

All Dissertations

Large Language Models (LLMs) have advanced conversational agents, enabling natural, human-like interactions in domains such as education, programming, and workplace collaboration. Yet, user distrust persists over privacy, accuracy, and bias. As developers work to mitigate these issues and human-AI collaboration expands, reinforcing trust in LLM-driven systems is essential. To address this problem, this dissertation explores the role of anthropomorphic form in LLM-driven conversational agents and its impact on user perception.

According to the familiarity thesis, humans attribute human-like characteristics to nonhuman entities — a process known as anthropomorphism — to better comprehend unfamiliar phenomena, based on the assumption that they …

Mir-181a-5p Mediates The Effects Of Bmp4 On Intestinal Cell Proliferation And Differentiation, Chang Li, Yuning Zhou, Zhijie Yin, Yinping Jiang, Jinpeng Liu, Heidi L. Weiss, Qingding Wang, B. Mark Evers

Surgery Faculty Publications

The intestinal mucosa undergoes a dynamic process of continual proliferation, differentiation, and apoptosis. Delineating the mechanisms involved in intestinal epithelial cell (IEC) differentiation is crucial to our understanding of not only normal gut adaptation but also aberrant intestinal growth. Bone morphogenetic protein (BMP) signaling is a pivotal regulator of intestinal proliferation and differentiation. However, the molecular underpinnings of the BMP pathway in this context are not entirely known. Here, we show a key role for the BMP4/microRNA (miR)-181/glycolysis signaling pathway in the maintenance of intestinal epithelial cell proliferation and differentiation. Treatment with BMP4 increased the expression of enterocyte markers and …

Ddt Exposure Induces Microglial Activation And Disease-Associated Microglial Signatures: Relevance To Mechanisms Of Alzheimer’S Disease, Isha Mhatre-Winters, Aseel Eid, Nicole Blum, Yoonhee Han, Ferass M Sammoura, Long-Jun Wu, Jason R Richardson

The Brown Foundation: Institute of Molecular Medicine

Background: Alzheimer's disease (AD) is characterized by the presence of amyloid-β plaques, neurofibrillary tangles, and neuroinflammation. Previously, we reported that serum levels of dichlorodiphenyldichloroethylene (DDE), the primary metabolite of the pesticide dichlorodiphenyltrichloroethane (DDT), were significantly higher in AD patients compared to age-matched controls and that DDT exposure worsened AD pathology in animal models.

Objective: Here, we investigated the effect of DDT on neuroinflammation in primary mouse microglia (PMG) and C57BL/6J mice.

Methods: DDT-induced inflammatory and disease-associated microglial (DAM) gene expression were determined in PMG by qPCR and immunocytochemistry, with and without pretreatment with the sodium channel antagonist tetrodotoxin (TTX). Furthermore, …
