Risk Factors And Prevention Of Alzheimer's Disease: How To Beat The Odds, Luke Magro

SPARK Symposium Presentations

Dementia affects over 55 million people worldwide. That number is expected to rise to 150 million patients worldwide, with the overwhelming majority of cases being Alzheimer's disease (AD). There is no cure or medicine that can cure Alzheimer’s disease; we can only try to prevent it. To prevent the rise in cases of Alzheimer's disease, we must learn what causes AD, what we can control, and how we can control it. What is known is that age, genetics, and family history are the main risk factors in 60% of AD cases. The other 40% are lifestyle factors such as diet, …

Ransomware As Organization: A Comparative Analysis Of Corporate And Criminal Structures In Conti, George Urling

Theses, Dissertations and Capstones

Cybercriminal groups continue to pose major threats to global cybersecurity. One of the most common types of cybercriminal groups are, “Ransomware-as-a-Service (RaaS)" groups, who create and sell ransomware. While research is conducted into the development of ransomware, there is limited reporting on the organizational structure and habits of RaaS groups. In 2022, prominent RaaS group Conti had their chat logs leaked, with the logs ranging from 2020 to 2022. This study seeks to provide a deeper understanding of RaaS group structures by utilizing the Conti leaked logs as a case study. The study, entitled “Ransomware as Organization: A Comparative Analysis …

Lifestyle Factors' Effect On Political And Religious Behavior, Madison A. Price

SPARK Symposium Presentations

There is a general understanding of an individuals’ political/religious beliefs when you analyze predictors like support of same sex marriage or views on abortion, but there is not a ton of research on how everyday lifestyle factors might affect how someone aligns themselves politically or religiously. Researchers have begun to expand the horizons of political and religious research by investigating how income, health, and politics affect religion (Francis-Tan & Tian, 2022), but there is a need to expand into more specific lifestyle factors. Which brings reason to question a few things: what lifestyle and demographic factors predict how religious someone …

A Macrocognitive Design Taxonomy For Simulation-Based Training Systems: Bridging Cognitive Theory And Human-Computer Interaction, Jessica M. Johnson

Virginia Digital Maritime Center (VDMC) Faculty Publications

Simulation-based training systems are increasingly deployed to prepare learners for complex, safety-critical, and dynamic work environments. While advances in computing have enabled immersive and data-rich simulations, many systems remain optimized for procedural accuracy and surface-level task performance rather than the macrocognitive processes that underpin adaptive expertise. Macrocognition encompasses higher-order cognitive processes that are essential for performance transfer beyond controlled training conditions. When these processes are insufficiently supported, training systems risk fostering brittle strategies and negative training effects. This paper introduces a macrocognitive design taxonomy for simulation-based training systems derived from a large-scale meta-analysis examining the transfer of macrocognitive skills from …

δ¹⁸O and δ¹³C values change in response to anthropogenic factors (Ghosh & Brand, 2003). Little is known about the effects of anthropogenic climate and land use change on the ecology of the Ohio River Valley. The goal of this research was to quantify the effects of European colonization on the native ecology of the region. The specific questions of this research were: (1) How have mammalian tooth enamel δ¹⁸O and δ¹³C compositions shifted over time within the Ohio River Valley in response to anthropogenic climate change and vegetation? (2) Are there differences …

Computational Clinical Judgment: Predicting Risk With Large Language Models, Hannah Laqueur, Ryan W. Copus

Faculty Works

For seventy years, research has shown actuarial methods outperform clinical judgment. Yet actuarial approaches have limitations: they generally rely on structured data; cannot exploit rare case-specific details; have limited accuracy where outcome data are scarce or incomplete; and cannot offer case-level justifications. Large language models (LLMs) offer a different approach. Like actuarial methods, they aggregate information algorithmically, but like clinicians, they bring general knowledge and can provide case-level justifications. We prompted seven LLMs to assess rearrest risk from 113 parole hearing transcripts and compared their predictions to a machine learning model trained on 4,000 cases with 91 administrative variables. GPT-5 …

Use Of Ai In Expert Testimony: Understanding The Attorney Perspective, Emma S. Puntin

Psychology Honors Papers

Artificial Intelligence is becoming increasingly incorporated into different aspects of society, including our legal system. AI has potential to enter into legal proceedings through the introduction of its evidence in case and expert witness testimony. Expert witnesses are called to offer knowledge on matters relevant to a case and can vary in specialization. This study aimed to explore how attorneys view experts who use AI and how they would approach this in a courtroom setting. Structured interviews were conducted with ten attorneys from various jurisdictions. During these interviews, attorneys were asked what they have encountered during their work in the …

The Information And Communication Behaviors Of Marcus Garvey And The Universal Negro Improvement Association (Unia), Janet Douglas-Pryce

Selected Full Text Dissertations, 2011-

Marcus Garvey, social activist and founder of the Universal Negro Improvement Association (UNIA) in the early twentieth century, has been widely studied for his Pan-African approach to the social upliftment of Black communities during a period marked by segregation and systemic injustice. His messages of empowerment attracted global attention and supported the growth of a movement that reached more than one million members worldwide. While Garvey and the UNIA have been examined from historical, political, and cultural perspectives, they have not been systematically studied through the lens of information and communication behavior. This study examines the information and communication behaviors …

The removal efficiency was 91.75% for WWTP A and 90.32% for WWTP B, with no statistically significant difference (p > 0.05). WWTP A employed advanced treatment units, whereas WWTP B used a conventional pond-based system. MPs were …

Assessment Of The Influence Of Human Activities On The Occurrence Of Forest Fires In Thailand Via Multiple Linear Regression (Mlr), Sittipong Ruktamatakul, Jirarat Insuk, Benjaporn Pinwongpet, Sarisa Ruktametakul, Pornpis Yimprayoon

Applied Environmental Research

Forest fires represent one of the most critical environmental challenges in Thailand, with impacts varying depending on forest type, fuel characteristics, terrain conditions, fire intensity, and the frequency of fire occurrence on the same landscape. While forest fires can contribute to ecosystem degradation, biodiversity loss, and the depletion of natural resources, such effects are not uniformly severe across all forest ecosystems. Understanding the human-induced factors contributing to forest fire occurrence is crucial for developing effective prevention strategies and promoting sustainable forest management. This study aimed to identify the anthropogenic factors influencing forest fire areas in Thailand via multiple linear regression …

Effect Of Chromium Doping On The Uv- And Sunlight-Driven Photocatalytic Performance Of Srtio3, Ro’Ikhatul Jannah, Dianisa Khoirum Sandi, Fahru Nurosyid, Risa Suryana, Didier Fasquelle, Yofentina Iriani

Applied Environmental Research

Chromium (Cr)-doped strontium titanate (SrTiO3, STO) photocatalysts with compositions of SrTi1-xCrxO3 (x = 0, 5, and 10%) were prepared via the coprecipitation method. This study aimed to investigate the effects of Cr doping on structural, morphological, and optical properties. Furthermore, this work aimed to examine the photocatalytic performance of pure and Cr-doped STO against methylene blue (MB) degradation under ultraviolet (UV) and sunlight exposure. X-ray diffraction confirmed the formation of the cubic STO phase and the insertion of the Cr dopant in the STO structures. Furthermore, Cr doping reduced the lattice constant, crystallite size, and average particle size and narrowed …

Investigating The Viability Of Fully Online Asynchronous Physics Instruction In Formal Education, Clifton W. Massey-Noel

Physics Dissertations

In this dissertation we present results from two consecutive investigations into the fully online asynchronous modality in Physics Education. We first discuss the efficacy of a fully online asynchronous section of Modern Physics held in Fall 2024. The asynchronous section is compared with four prior partially-flipped sections of the same class, two of which were held in-person, and two of which were held synchronously online. Results suggest that all three modalities can be made to be about equally as effective. We also discuss the efficacy of a fully online asynchronous section of Calculus-Based Introductory Mechanics held in Fall 2025. The …

Human Movement Studies & Special Education Faculty Publications

Public schools face significant challenges, including rising student behavioral needs, chronic absenteeism, and high rates of teacher burnout. These issues are interconnected with and inextricably linked to a need for effective, evidence-based behavioral supports. Educators frequently enter the field lacking the necessary skills and training to manage complex student behavior, often resulting in a reliance on punitive practices that exacerbate problems.

This paper proposes that the expertise of school-based behavior analysts (SBBAs), who are Board Certified Behavior Analysts® (BCBAs®) specializing in education, offers a powerful, underutilized solution. SBBAs are trained in applied behavior analysis (ABA), a data-driven science focused on …

"What Power Do We Have?" Community Capacity And Justice In Samoa, California’S Floating Offshore Wind Terminal Development, Lauren Mccall Hart

Cal Poly Humboldt theses and projects

Floating offshore wind (OSW) is a relatively novel technology in the United States, which is positioned to play an integral role in California’s decarbonization strategy. Two federal OSW lease areas have been established off the coast of Northern California, and plans are underway to develop supporting port infrastructure, including the Humboldt Bay Offshore Wind Heavy Lift Marine Terminal (HLMT). The proposed HLMT site is adjacent to communities on the Samoa Peninsula of Humboldt Bay, which currently face socio-environmental vulnerabilities and critical infrastructure gaps. The social implications of OSW port development remain poorly understood, particularly in rural and underserved communities. This …

Labor Market Impacts Of Immigration Enforcement: Evidence From The Second Trump Administration, Rachel Letts

Economics Honors Papers

The onset of the second Trump Administration saw a stark immigration policy shock in the U.S. with record numbers of Immigration Customs Enforcement (ICE) detentions. This paper seeks to understand the labor market impacts of this immigration enforcement that have disproportionately affected the risk of being detained for non-white individuals. To estimate the effect of this policy shock, a triple difference model is used comparing non-white individuals to white individuals living in Metropolitan Statistical Areas (MSAs) with above or below average concentrations of immigration detentions before and after this immigration shock. The regression analysis finds that since the beginning of …

The Dunning-Kruger Effect In Sixth Grade Adolescents: Improving Metacognition For Self-Regulated Learning, Julie H. Chen

Scripps Senior Theses

The Dunning-Kruger (DK) effect is a cognitive bias where low-performing individuals overestimate their own abilities, and top-performing individuals underestimate their own abilities relative to their peers. The purpose of this proposed study is to investigate the DK effect in sixth grade adolescents and to use metacognition as an intervention to improve self-assessment calibrations. This study will investigate adolescents in Piaget’s formal operational stage, aiming to improve metacognition levels. The study will occur over 12 weeks, and participants will be given a preparation handbook with or without metacognition activities for the purpose of preparing for the California Assessment of Student Performance …

Effects Of Teacher Training On Identifying Inattentive Type Adhd In Afab Students, Gabrielle A. Boles

Scripps Senior Theses

Teachers are more likely to detect hyperactive ADHD symptoms than inattentive ones, which often results in students, especially girls with inattentive symptoms, being under-referred (Willcut, 2012). This study evaluates whether a targeted, inattentive-focused, and gender responsive teacher training reduces gendered and symptom-based biases in referral decisions. K-5 teachers will be randomly assigned to receive either standard general ADHD identification training or an inattentive-focused, gender-responsive training, and will then be asked to review vignettes depicting children with hyperactive and inattentive symptoms, with varying student genders. Referral accuracy and knowledge of ADHD will be measured. Training condition, symptom presentation, and student gender …

Formation-Based Ai Ethics: Ethical Formation, Responsibility, And Opportunity Cost In Ai Ecosystems, Maurice Emelu

2026 Faculty Bibliography

Recent efforts in AI ethics have been dominated by the proliferation of high-level principles intended to guide responsible development and deployment. Yet persistent implementation failures suggest that principlism and tool-based approaches alone do not cultivate the moral capacity required to govern sociotechnical systems. This article advances a formation based framework for AI ethics that situates moral agency throughout the developmental conditions of design, use, and the AI lifecycle. Drawing on Aristotelian-MacIntyrean virtue ethics applied to media ecology, and sociotechnical responsibility, the argument reframes AI as a formative environment that shapes patterns of attention, judgment, delegation, and accountability over time. Against …

Hegemonic Microtonality: Decolonizing The Soundscape Of Music Theory Pedagogy, Ash K. Wetty

Honors Theses

This thesis examines how Western music theory pedagogy—long organized around tonal and twelve-tone equal-temperament frameworks—structures both what is taught and how students are trained to listen. Through a literature review tracing the historical construction of tonal universality in undergraduate curricula, the project argues that dominant models of music theory reproduce broader epistemic hierarchies inherited from Western conservatory traditions. Situating these histories within my own experience as a student navigating institutional listening norms, the thesis combines critical self-reflection with ethnographic research conducted across five liberal arts institutions, including the CBB consortium and JanPlan research at Wesleyan University and Amherst College. Rather …

Near And Dear: How Proximity To Amenities Shapes Land Value In Maine, William Kopans

Honors Theses

Residential land values reflect the benefits of accessibility to amenities as well as the costs associated with commercial activity. This trade-off is particularly important in Maine, a predominantly rural state where most households rely on automobiles to access employment, retail, and civic amenities. Drawing on hedonic theory, I analyze how households value proximity to public and private amenities located within downtowns and shopping centers. Using parcel-level transaction data from ATTOM combined with amenity data from OpenStreetMap, I construct a novel approach that differentiates downtown and shopping center clusters across the state. The findings demonstrate that properties located immediately adjacent to …

Uncertainty-Aware Estimation, Planning, And Control For Tracking Multiple Drifting Patches In Flow Fields, Daniel O. Akanji, Krishnanand N. Kaipa, Cong Wei

Mechanical & Aerospace Engineering Faculty Publications

In this study, we present a replay-based framework for uncertainty-aware persistent tracking of multiple advected surface patches using an autonomous marine vehicle operating in spatiotemporal-varying currents. The method combines three components: local flow estimation, covariance-aware patch-boundary propagation with intermittent boundary fusion, and mission-level scheduling over multiple patches. Each patch is represented by a polygonal boundary, whose vertices are propagated through the estimated flow field while carrying per-vertex covariance, thereby quantifying uncertainty growth during advection. A flow-aware gain-scheduled linear quadratic regulator (LQR) was designed to shape the desired surge speed to take advantage of favorable currents. When the vehicle services a …

Scanning Electron Microscopy As A Potential Tool For Distinguishing Charcoal From Dark, Oxidized, Biomass, João Vitor Dos Santos, Aleksandar I. Goranov, Lais Gomes Fregolente, Joao Marcos De Lima-Faria, Diego Stefani Teodoro Martinez, Patrick G. Hatcher

Chemistry & Biochemistry Faculty Publications

Condensed aromatic carbon (ConAC) is widely used as a proxy for organic materials derived from biomass burning. However, recent evidence shows that ConAC can be also formed through nonpyrogenic oxidative processes. This study presents a proof-of-concept investigation using scanning electron microscopy (SEM) to distinguish charcoal from dark, ConAC-rich materials produced by ambient oxidation of biomass. Pine wood exposed to long-term iron-mediated oxidation was compared with unaltered wood and a controlled laboratory-generated charcoal reference. Conventional geochemical analytical methods, including benzenepoly(carboxylic acid) (BPCA) analysis, Fourier transform–ion cyclotron resonance–mass spectrometry (FT-ICR-MS), solid-state 13C nuclear magnetic resonance (NMR) spectroscopy, and elemental analysis, confirmed substantial …

Information Design And Mechanism Design: An Integrated Framework, Dirk Bergemann, Tibor Heumann, Stephen Morris

Cowles Foundation Discussion Papers

We develop an integrated framework for information design and mechanism design in screening environments with quasilinear utility. Using the tools of majorization theory and quantile functions, we show that both information design and mechanism design problems reduce to maximizing linear functionals subject to majorization constraints. For mechanism design, the designer chooses allocations weakly majorized by the exogenous inventory. For information design, the designer chooses information structures that are majorized by the prior distribution. When the designer can choose both the mechanism and the information structure simultaneously, then the joint optimization problem becomes bilinear with two majorization constraints. We show that …

Extreme Points And Majorization, Andreas Kleiner, Benny Moldovanu, Philipp Strack

Cowles Foundation Discussion Papers

Many seemingly different economic problems share a common mathematical structure: they involve the maximization of a functional over sets of monotonic functions that are either majorized by, or majorize, a given function. This paper presents new, simpler proofs for the main characterization results of the extreme points of sets defined by monotonicity and majorization constraints obtained by Kleiner, Moldovanu, and Strack (2021). It demonstrates how these characterizations can be applied to a broad range of economic applications, including auction and information design, contest design, optimal delegation, optimal stopping, and decision problems under risk. The paper concludes with an overview of …

All Games Have Equilibria, Arthur Paul Pedersen, M. Ali Khan, Maxwell B. Stinchcombe

Publications and Research

Research on Nash equilibrium existence for infinite games has grown into a patchwork of technical preconditions and counterexamples. This paper presents a unified program in equilibrium theory by revising the predominant model of mixed strategies based on countable additivity. A game is specified by a nonempty set of players and, for each player, a nonempty action set and a bounded von Neumann-Morgenstern utility function. Every such game is shown to admit a Nash equilibrium in finitely additive mixed strategies. In addition, the equilibrium correspondence for any such game is shown to be nonempty, compact-valued, and upper hemicontinuous, and the same …

School of Social Work Faculty Publications

This study explored the trajectories of well-being among immigrant youth in the United States using an ecodevelopmental and posttraumatic growth perspective. Immigrant youth were from the Northern Triangle of Central America and had recently been released from immigration family detention in the United States. Through time-ordered matrix thematic analysis of interviews with 15 mothers at baseline and follow-up (N = 30 interviews), the research revealed a complex landscape of challenges and adaptations during resettlement. While initial adverse emotional outcomes were common, these tended to improve over time as families gained stability in the United States. Family structure emerged as …

Operationalizing Cyber-Routine Activities Theory For Senior Cybercrime Prevention: An Evaluation Of The Shield Training-The-Trainer Program, Kyung-Shick Choi, Insun Park, Mijin Kim, Ji Yae Bong

International Journal of Cybersecurity Intelligence & Cybercrime

Older adults face growing risks of cyber-enabled fraud, yet scalable, evidence-based prevention programs remain limited. Guided by Cyber-Routine Activities Theory (Cyber-RAT), this study evaluates the pilot implementation of the Seniors Harnessing Internet Education for Lasting Defense (SHIELD) Training-the-Trainer program, designed to prepare law enforcement officers and community leaders to deliver cybercrime prevention education to older adults. A key innovation of SHIELD is its integration of interactive game-based simulations, which allow participants to practice verification, refusal, and reporting behaviors in realistic cybercrime scenarios. Following the December 2025 pilot session in Boston, semi-structured interviews were conducted with 12 participants from law enforcement, …
