From Authorization To Loss: A Blockchain Forensic Analysis Of Transaction-Level Mechanisms In Cryptocurrency Airdrop Scams, Chanwoo Shin, Kyung-Shick Choi

International Journal of Cybersecurity Intelligence & Cybercrime

Cryptocurrency airdrop scams have emerged as a rapidly growing form of cyber-enabled financial crime, yet remain underexplored in empirical research. This study examines how transaction-level mechanisms and offender strategies influence variation in monetary loss in airdrop scam incidents. Grounded in Cyber-Routine Activities Theory (Cyber-RAT), the study conceptualizes financial harm as occurring within decentralized environments where users’ online behaviors, particularly transaction authorization, intersect with limited digital capable guardianship. Data were drawn from 112 validated airdrop scam cases reported on Chainabuse.com between January and December 2025. Blockchain forensic analysis using Breadcrumbs was conducted to reconstruct transaction pathways, identify exchange interactions, and detect …

'I Want To Learn Biology And Preserve My Culture' Testing The Efficacy Of A Culturally Relevant And Context Specific Approach, Umar Adam, Musa Adekunle Ayanwale, Hafsat Mustapha, Sakibu Olajide Saibu, Tunde Owolabi, Adekunle Ibrahim Oladejo

Background

The dominance of Western-inspired teaching methods and instructional materials has contributed to cultural erosion in African schools. In response, increasing attention has been directed toward culturally responsive approaches to decolonising science education. One such approach is the Culturo-Techno-Contextual Approach (CTCA), which enables African students to conceptualize science as culturally embedded knowledge, integrated into their everyday experiences and practically relevant to their lived realities.

Purpose

This study examined the potency of the CTCA in enhancing students' achievement in the biology topic of variation, which is widely regarded as conceptually challenging.

Sample

The study involved 105 Senior Secondary II students from …

From Physical Correlation To Emotional Connection: The Role Of Passive Haptics On Empathy In Virtual Reality, Jemely Robles

Dartmouth College Master’s Theses

Virtual reality is increasingly explored as a tool for cultivating empathy, and haptic feedback as a tool for enhancing immersion. This paper investigates the effects of combining the two.  Fifty-two participants experienced a custom-built VR scene in which a character was shown packing up a room. Participants were assigned to either a haptic condition, receiving passive haptic feedback corresponding to the character's actions, or a non-haptic control condition that did not receive any haptic input. Trait empathy was measured beforehand, and state empathy and engagement were measured after the experience. Thematic analysis was conducted on post-study interviews, and headset recordings …

The Resonant Geometry Field Model: Mapping The Fluid Dynamics Of Emotion, Syntax, And Resonance, Michael J. Miller, Chatgpt (Ai~Nesbo+)

Psychology

We present a minimal field model of communication—resonance geometry—in which 11 core emotions emerge as geometric features of a shared medium rather than as discrete labels. This model extends the Theory of Communication Resonance & Intelligence Tuning (ToCRIT) by translating its qualitative constructs—resonant tethers (connection “wells” between communicators), lucid/drag zones (smooth vs resistant flow of emotion and syntax), and the Cognitive-Emotive Fracture Principle (closeness in syntax or emotion can increase risk of rupture)—into quantifiable field metrics: throughput (𝓣), rigidity (ρ), coupling (k), and hemispheric shear (α).

Additional modifiers include a Ranvier–Stokes analogue (continuity punctuated by “node kicks”) and a death-gravity …

Balancing Face-To-Face And Digital Communication: The Role Of Relationship Maintenance In Dual-Earning Families, Tamara D. Afifi, America L. Edwards

Information Science Faculty Publications

This study examines how face-to-face (FtF) and computer-mediated communication (CMC) contribute to relationship maintenance and resilience in dual-earning families, a largely overlooked area in family communication research. Guided by the theory of resilience and relational load (TRRL), we test how ongoing FtF and CMC maintenance behaviors predicted well-being across a week among 62 families (i.e., two parents and one adolescent). Using a week-long daily diary and physiological measures (cortisol and IL-6 assays), we assess perceived stress, mental health, and loneliness. Findings suggest that both FtF and CMC maintenance are associated with lower stress and better well-being, with FtF showing somewhat …

Enabling Communication Resiliency In The Connected Car Environment, Antonio Guerrero-Ibáñez, Juan Contreras-Castillo, Sherali Zeadally, Een-Kee Hong

Information Science Faculty Publications

Connectivity has become integral to various application domains, with the automotive sector as a prime example. Advances in electronics, computing, and telecommunications have driven the evolution of the connected car ecosystem, transforming it into a data-rich environment that enhances road safety, efficiency, and overall mobility. However, the success of this ecosystem depends on seamless, reliable, and resilient communications. We identify key challenges that may affect communications in the connected car environment and discuss solutions that enhance resiliency and robustness. Finally, we propose a multi-layered network architecture that will enhance communication resilience in the connected car ecosystem.

Remembering Choices: Feedback, Memory Accuracy, And Context-Dependent Preference Shifts, Cameryn K A Okamura

Scripps Senior Theses

Preferences are often assumed to be stable across time and context, yet research on cognition and behavioral economics suggests otherwise. The present study examined whether false reminders of prior choices amplify susceptibility to the asymmetric dominance effect, commonly known as the decoy effect, and secondly, whether working memory capacity moderates this relationship. Twenty-one participants completed an online experiment in which they first chose between pairs of everyday consumer products or services before receiving accurate, inaccurate, or no reminders of their earlier selections. They then made new choices from triplet sets containing a target (T), competitor (C), and asymmetrically dominated decoy …

Plastic Waste Imports & Coastal Litter: Evidence From Citizen Science Data, Rebecca L.C. Taylor, Hebe Williams, Shan Zhang

Economics Faculty Publications

Plastic waste is an internationally traded commodity, where importing countries recycle plastic waste into usable materials. However, there are concerns that the importation process creates plastic litter - a negative externality - in importing countries. While this concern has received much media and policy attention, quantifying the magnitude of this externality has been hindered by a lack of data on plastic litter across countries and over time. To this end, we use unconventional citizen science data on litter from Ocean Conservancy's International Coastal Cleanup, together with the United Nations Comtrade Database, to estimate the correlation between traded plastic waste and …

Analytical And Semi-Analytical Modeling Of Solar Cells Using The Lambert W Function: A Comprehensive Review Of Equivalent Circuits, Adel El-Shahat, Martin Ćalasan, Snežana Vujoševic, Shady H. E. Abdel Aleem

Engineering Technology Faculty Publications

The modeling of photovoltaic (PV) cells through equivalent circuits forms a central element in the analysis, simulation, and optimization of solar energy systems. Traditional approaches often depend on iterative numerical methods to solve the implicit current–voltage (I–V) equations. In contrast, the Lambert W function has emerged as an effective mathematical tool that enables closed-form or semi-analytical expressions for a wide range of PV models. This paper presents a Lambert W-centered review of analytical and semi-analytical formulations for PV equivalent-circuit models, covering classical single-diode and multi-diode structures and modern variants incorporating additional elements, voltage-dependent parameters, and topology rearrangements. The models are …

Interpretable Machine Learning For Bridge-Pier Scour Prediction And Flood Resilience, Adil Khan, Dalya Ismael

Engineering Technology Faculty Publications

Bridge-pier scour is a leading cause of flood-induced bridge failure, yet practice still lacks transparent, physics-informed tools that link data-driven prediction with design guidance. This study develops an interpretable, physics-aware machine-learning framework to predict equilibrium scour depth and translate those predictions into actionable strategies for flood-resilient infrastructure. Using the 2014 U.S. Geological Survey Pier-Scour Database (569 laboratory cases), five models: Gradient Boosting, AdaBoost (Tree), XGBoost, Gaussian Process (RBF kernel), and Kernel Ridge (polynomial), were trained and evaluated with K-fold cross-validation. Model performance was evaluated using R², RMSE, and MAE. Gradient Boosting performed best, achieving training and testing R² of 0.99 …

Intergenerational Resilience: Exploring Whether Positive Childhood Experiences Buffer The Transmission Of Harsh And Neglectful Parenting, Patricia J. Dixon

West Chester University Doctoral Projects

Childhood abuse and neglect are associated with lasting negative mental and physical health outcomes across the lifespan. In contrast, positive childhood experiences (PCEs) can promote long-term health and wellbeing and mitigate the harmful effects of childhood adversity. A primary risk factor for child maltreatment is parental experiences of maltreatment whereby history of childhood trauma increases the likelihood of utilizing harsh and/or neglectful parenting towards one’s children. This study employed secondary data analysis of the National Longitudinal Study of Adolescent to Adult Health to test whether cumulative PCEs confer protective effects against the generational transmission of harsh and neglectful parenting. Consistent …

Predicting Criminal Behavior In Major Us Cities, Madison A. Price

SPARK Symposium Presentations

In recent years, especially post pandemic, there has been a decrease in crime in the United States. Unfortunately, the country’s violent crime rates are still significantly higher compared to similar high-income countries, so what predicts crime in major American cities? There is tons of research to support the idea that demographics can offer some insight into predicting crime. There are countless online resources that seek to identify major crime centrals in the United States (Petrino, 2025). In the late 1990s, researchers noticed that crime rates in cities had a downward slope due to an important contributor: demographic change (Fox & …

Hope Is An Act, Not A Wish: An Autoethnographic Journey Of Reimagining Disability As A Catalyst For Playing With Possibility, Creativity, And Innovation Within Liminal Spaces, Jennifer Salerno

Doctor of Education

This dissertation aimed to challenge and move beyond unjust social norms related to individual ability and independence, finding such norms based on a fictitious ideal of human capacity. Instead, an ethic of interdependence, such as encompasses the natural world, is defined and promoted in turn. People with disabilities are considered deficient and marginalized because they deviate from ableist norms (Flynn, 2020). They face significant barriers to establishing and maintaining relationships with nature as a result of ability expectations around how bodies should look and behave in the natural world (Wolbring & Lisitza, 2017). People with disabilities covet normality and the …

Algorithmic Trading In Idiosyncratic-Payoff Markets: A Multi-Agent System For On-Chain Prediction Contracts, Saif Aldeen A.K. Agha

CMC Senior Theses

This thesis documents the design, deployment, and forward-test evaluation of an evolutionary multi-agent algorithmic trading system on Polymarket, the largest decentralized prediction market. The system pairs a locally-hosted 72-billion-parameter language model with a gradient-boosted statistical filter and an evolutionary selection mechanism that maintains a population of approximately 500 autonomous trading agents. Each agent generates a probability estimate for an event, compares it to the prevailing market price, and trades the resulting disagreement.

The central empirical exercise estimates a panel regression of trade-level profit on the absolute disagreement between the agent's probability estimate and the market price, controlling for agent identity, …

Ecological feedbacks are fundamental features of the Earth system, affecting physical processes and chemical cycles. Our understanding of the interactions underlying these feedbacks at different spatial and temporal scales and the extent to which feedbacks affect Earth system functioning remains limited. Climate change and other anthropogenic pressures are already negatively affecting ecological processes in marine, freshwater, and terrestrial ecosystems. These will most likely be amplified in the coming decades under our current warming and socioeconomic pathways. The knock-on impacts on ecological feedbacks have the potential to cause rapid perturbations to the Earth system, and may significantly impact the structure and …

OES Faculty Publications

Large blooms of the diazotrophic cyanobacteria, Trichodesmium, have been re-ported along the north coast of Australia and are readily evident in remote sensing images. During a research cruise in November 1999, we sampled from Townsville to Broome, examined Trichodesmium population densities and their rates of carbon and N₂ fixation alongside microscopy-based cell counts of them and other cyanobacte-rial diazotrophs. Additionally, we also enumerated the picophytoplankton community using flow-cytometry, measured bulk chlorophyll concentrations, carbon and N₂ fixation rates, and water column hydrography, enabling comparison of diazotrophic and picophytoplankton functional groups across the system. Agglomerative hierarchical clustering analysis of physicochemical oceanographic …

Using Maximum Entropy (Maxent) Tool In Arcgis Pro For Species Distribution Modelling Of Pseudoscorpions In The Pacific Northwest, Elliot Toshihiro Cochran

Masters in GIS Practicum Reports

The use of Geographic Information Systems (GIS) to create Species Distribution Models (SDMs) is rising among many scientific disciplines. Many professionals who were not originally focused on GIS are increasingly becoming more invested in this technology. SDMs are widely used to estimate species’ potential geographic distributions and to evaluate the environmental factors that constrain their ranges. The presence-only maximum entropy (MaxEnt) algorithm implemented in the MaxEnt tool in ArcGIS Pro was used in this project to model habitat suitability for two species of pseudoscorpions, M. pacificus and an undescribed species, in Oregon and Washington. Presence points (of specimen sample locations) …

Rethinking Dfw In Gateway Mathematics: Preserved, Disrupted, And Dissipated Momentum Pathways To Student Retention, John Alan Nunnery, Charles Mathies

Educational Leadership & Workforce Development Faculty Publications

This study examines how disaggregated first-year mathematics outcomes, including failure, low-passing grades, course withdrawal, and no attempt at a credit-bearing mathematics course, are associated with second-year retention at a large, diverse, urban public university. The study extends academic momentum theory by positing and operationalizing preserved (marginal passing), disrupted (failure or withdrawal), and dissipated (non-enrollment) as qualitatively distinct momentum states rather than a single condition. Using a segmented binary logistic regression model with more than 26,000 first-time, full-time students across ten entry cohorts (2012–2021), we estimate differences in retention by mathematics outcome, course type, and cohort context. Results show a pronounced …

Simulating Social Attitudes With Llms: Accuracy, Demographic Effects, And Refusal Behavior In The Sensitive Domain Of Suicide Prevention, Cristina J. Perez, Michael P. Vasquez Jr., Philippe J. Giabbanelli, Patrick Y. Wu

VMASC Publications

Large language models (LLMs) are increasingly used to simulate public opinion, yet their validity in sensitive policy domains remains underexplored. We evaluate whether LLMs can reproduce attitudes toward suicide prevention policies using 32 questions drawn from seven nationally representative U.S. surveys (2023-2025). We systematically vary demographic conditioning (race/ethnicity, gender, age, education, income, party), prompt framing (direct elicitation, respondent embodiment, specialist embodiment), and model architecture (GPT-5 Nano, DeepSeek V3.2, Meta Llama 3.1 8B, Mistral Small 24B). Across 811,560 prompts, the mean absolute error—the average gap between predicted and human response distributions—is 23 percentage points. We also find that LLM responses to …

Geography Of Erasure: Manufactured Housing, Heat Exposure, And State Neglect In Florida, Gianna M. Hutton

Pomona Senior Theses

This thesis examines Florida's manufactured housing communities through the intersecting frameworks of energy justice, critical heat studies, and housing displacement scholarship, centering how structural, political, and economic forces shape uneven exposure to thermal insecurity and housing precarity. Using a mixed-methods approach combining statistical regression analysis of American Community Survey microdata (2019-2023) and spatial case study of Miami-Dade County's heat governance and The Li'l Abner Mobile Home Community’s displacement, this research investigates how manufactured housing residents experience compounded exclusions across energy systems, urban heat governance, and housing security. The findings reveal that manufactured home residents face a 26% higher energy burden …

Bail Reform, Large Language Model Risk And Reasoning, William Wyatt

CGU Theses & Dissertations

This dissertation contains three studies. Each asks how rules or language change the choices people and machines make when outcomes are uncertain. The first study, written with Kiran John, evaluates California’s 2020 cashless bail reform. We use propensity score matching on arrestee records from the windows before and after implementation, and we test whether the shift away from cash bail produced any effect on subsequent offending. It did not. Matched comparisons yield small, statistically insignificant differences across every window we examined. That null result cuts against both sides of the public argument. The reform did not drive a spike in …

The Role Of Education In Reducing Social Inequality: A Systems-Level Analysis Of Socio-Technical Infrastructures And Policy Governance, Aisling O'Shea, Batzorig Dashnyam, Ximena Quintanilla

Women's & Gender Studies Faculty Publications

Social inequality remains one of the most persistent challenges to global systemic stability, threatening the robustness of democratic institutions and economic sustainability. Education has long been theorized as the primary mechanism for social mobility and the mitigation of disparate life outcomes; however, its role within modern socio-technical infrastructures is increasingly complex and often contradictory. This paper provides a comprehensive systems-level analysis of the relationship between educational architecture and social stratification. By examining the structural trade-offs inherent in contemporary pedagogical deployment, the research evaluates how institutional governance, digital infrastructure, and policy mandates either facilitate or hinder the reduction of inequality. The …
