"Chatcbt”: Understanding The Implications Of Artificial Intelligence In Cognitive Behavioral Therapy, Esther R. Goldberg

Scripps Senior Theses

The proposed study is intended to explore the impacts of artificial intelligence (AI) tools when used in cognitive behavioral therapy (CBT) to treat anxiety in American adults. The research is designed to measure whether AI systems such as large language models (LLMs) provide sufficient therapy through the factors of empathy, coping skills, and anxiety symptom reduction. Human therapists are hypothesized to surpass chatbots in all three. Through an experimental design, participants will be placed in either an AI therapy condition or human therapy condition. Participants will undergo a 12-week CBT program, after which they will measure anxiety reduction, perceived empathy …

Spectral Decimation On The Schreier Graphs Of The Basilica Group: A Thesis In Fractal Analysis, Anne D. Bannon

Scripps Senior Theses

This thesis is intended to provide a comprehensive overview of the literature required to fully understand research conducted during the University of Connecticut's Fractals & Stochastics REU in the summer of 2025. The literature review includes a description of Robert Strichartz's seminal work pertaining to the Laplacian spectrum of the Sierpiński Gasket, which provides a framework for how we approach studying the spectrum of the basilica Julia set. Defining the basilica Julia set and the closely-related Basilica group involves graph theory, automata theory, iterated monodromy group theory, and amenable group theory. Further time is dedicated to defining the graph Laplacian …

relevant notions in functional analysis first, and use these concepts to study

real interpolation using J. Peetre’s 𝐾-functional in some detail. We also

explore the basics of approximation theory, in particular the connection

between approximation and interpolation results.

Civic Grammar: Why Classical Architecture Endures In The American State, Jesse Walker

Master of Liberal Studies Theses

The dominant visual language of American federal buildings has been classical, surviving repeated ideological challenges, professional revolts, and political controversy. While this persistence has been widely observed, the mechanism behind it has not been clearly identified. This thesis isolates that mechanism. Drawing on architectural history, federal procurement policy, and primary sources from Jefferson's correspondence through the executive orders of 2020 and 2025, it argues that classicism endures not because its meaning has remained stable, but because federal architecture is governed by a persistent functional constraint: government buildings must be immediately legible to an ordinary citizen, without signage or prior knowledge, …

The Importance Of After-School Programs For Middle And High School Students, Chelsey Wright

Integrated Studies

After-school programs for middle and high school students have become an important part of today’s education system. They started as safe places for students after-school, but now they also help students succeed academically, develop social and emotional skills, involve families, and offer more learning opportunities. Programs like the 21st Century Community Learning Centers (21st CCLC) are among the largest federally funded after-school efforts in the U.S., focusing on underserved and high-poverty areas. This paper reviews national studies, peer-reviewed research, meta-analyses, dissertations, conference presentations, and insights from practitioners, including an interview with Hillary Bumpus, a program coordinator with ten years of …

Stress-Strain Behavior Of Saturated Clays From Vane Shear Test Results: A Numerical Approach, Gustavo Rodrigues De Avila Oliveira

Master’s Theses

The vane shear test (VST) is widely used to estimate the undrained shear strength of soft cohesive soils; however, it does not directly provide constitutive information such as the stress–strain response. Smoothed Particle Hydrodynamics (SPH), a mesh-free numerical method, offers an attractive alternative for modeling the large deformations involved in the VST and extracting additional information from the test.

This study develops and calibrates a two-dimensional SPH model to simulate the field vane shear test and investigate the stress–strain behavior of soft soils. The VST was implemented within an SPH framework, while field and laboratory data were used to define …

Analysis Of The Complex Nmr Lineshape Of Polarized Deuterons, Michael Joseph Mcclellan

Doctoral Dissertations

To determine the spin polarization of deuterons, nuclear magnetic resonance (NMR) is used. This is necessary for polarized targets, such as for the upcoming $A_{zz}$ and $b_{1}$ experiment at Jefferson Lab. These polarized target experiments are expected to discriminate between different models of the deuteron, which in turn could lead to a better understanding of short-range correlations (SRCs). NMR measures the impedance of a solenoid around a deuterated sample. Although the impedance is a complex value, conventionally only the real part of the impedance has been used for this purpose. However, often the tune is not precisely real, meaning the …

Performance-Based Funding’S Influence On Higher Education Through The Eyes Of Department Chairs, Jonathan W. Lackland

Theses and Dissertations

Performance-based funding (PBF) has become a widely adopted policy in higher education, linking state appropriations to measurable outcomes such as graduation rates, degree completions, and workforce alignment. While PBF aims to enhance institutional accountability and efficiency, its implementation has raised significant concerns about equity and political influence. This dissertation examines the political equity and implications of PBF policies through a mixed-methods approach, including surveys, interviews with department chairs, and critical discourse analysis of state statutes and legislative debates. The findings reveal that PBF often exacerbates inequities, particularly for non-flagship universities serving diverse and under-resourced student populations. Department chairs expressed concerns …

An Application Of Molecular Dynamics To Hed Plasma Physics: Point And Group Defect Diffusion In Coulomb Crystals, Levi Webb

Theses and Dissertations

Molecular dynamics (MD) simulations are used to explore the microscopic behaviors of complex systems that cannot be easily studied experimentally. In particular, the microphysics of high energy density (HED) astrophysical plasma environments remain inaccessible by modern experiment---even in laser facilities, these plasmas exist only on short timescales that do not lend easily to investigation. The diffusion of point and group defects through crystallized plasmas in the cores of white dwarfs and neutron star crusts, called Coulomb crystals, has potentially macroscopic implications for the evolution of these bodies. Thus, I employ the widely-used MD code LAMMPS to simulate small Coulomb crystal …

Identifying Risk-Free Asset Proxies In Companies Listed On The Indonesia Stock Exchange From 2017 To 2023 Using The Zero-Beta Capital Asset Pricing Model, Fajri Alan Ghazali Mr., Lenny Suardi Mrs.

The Indonesian Capital Market Review

This study evaluates Bank Indonesia Certificates (SBI), IndONIA, and gold as zero-beta proxies for Indonesian equities. Using daily returns for 213 firms listed on the Indonesia Stock Exchange (2017–2023) and the Jakarta Composite Index as the market return, we estimate firm-level zero-beta CAPMs and compute Wald statistics test to identify the appropriate risk- free asset proxy for each individual company; and firm-level outcomes are then aggregated under a Bernoulli/Binomial criterion with a 95% threshold. Empirical results show that gold satisfies the zero-beta condition for 207 of 213 firms (97.18%), whereas SBI and IndONIA satisfy it for five (2.35%) and six …

Feasibility Of Upcycling Spent Lithium-Ion Battery To Carbon Dioxide Capture Adsorbent, Chimezie Frank Onwudinjo

Master’s Theses

This study investigates the feasibility of repurposing spent lithium-ion battery (SLIB) to lithium orthosilicate (Li₄SiO₄), a high temperature carbon dioxide sorbent. Two synthesis pathways including conventional acid-leaching method (Scenario 1) and a pyrolysis-based route (Scenario 2) were explored. Additionally, techno-economic analysis (TEA) and lifecycle assessment (LCA) of the two processes were also performed. Different analytical characterization techniques were performed to understand the material properties of Li₄SiO₄ including surface area, crystallinity, morphology and thermal stability. CO₂ capture performance of the synthesized Li₄SiO₄ was tested in a thermogravimetric analyzer (TGA) using …

Control System Emendation And Ai-Driven Optimization For Enhancing A Smart Residential Microgrid, Anthony Nyoyoko

Master’s Theses

This thesis began with a simple idea: to restore the control system of a smart residential microgrid to respond intelligently to electricity prices while remaining safe, reliable, and practical on low-cost hardware. At the start, the goal was to design an economically aware microgrid that could look at electricity prices from the PJM market and make better operational decisions than traditional rule-based control. The motivation was straightforward. As residential renewable energy adoption increases, microgrids are expected to do more than just supply power. They are expected to respond to price volatility, integrate renewable generation, and operate reliably using embedded controllers …

Stochastic Mechanical Mesoscale Modeling Of Cylindrical Cavities In Metallic Foams, Mujan N. Seif, Alexandre Martin, Matthew J. Beck

Chemical and Materials Engineering Faculty Publications

Aluminum foam is a critical component of state-of-the-art micrometeoroid and orbital debris shielding. However, its randomly oriented constituent ligaments create significant variability in properties at different length scales. Previous efforts have thoroughly characterized the statistical implications of micro- to macro-scale-length transitions on the homogenized elastic behavior of damage-free, pre–micrometeroid and orbital debris (MMOD) strike structures. In this work, the properties of the residual material post MMOD impact are assessed by introducing cylindrical cavities representing the damage track. It was observed that configuring the cavity parallel to the through-the-thickness direction transformed a nominally isotropic foam into an anisotropic (transverse isotropic) material, …

Beyond The Lace Index: Benchmarking Machine Learning Architectures And Explaining 30-Day Hospital Readmission Risk With Shap Analysis, Carl E. Hughes Iii

Williams Honors College, Honors Research Projects

Unplanned 30-day hospital readmission remains a fundamental challenge in US healthcare, associated with increased risk to patient recovery and representing an estimated $52.4 billion in annual expenses (Beauvais et al., 2022). While the rigorously validated LACE index serves as the clinical standard for readmission modeling, its linear structure and four explanatory variables lack the complexity to capture the high-dimensional and interactive nature of patient risk. This study utilizes an admission granularity level cohort of the MIMIC-IV database to develop and compare machine learning architectures against the baseline LACE index. Due to the imbalanced prevalence of readmission, the penalized logistic regression, …

Rate Response Of Curlyleaf Pondweed And Native Plants To Flumioxazin In Minnesota Lakes, Pearl J. Jensen

All Graduate Theses, Dissertations, and Other Capstone Projects

Curlyleaf pondweed (Potamogeton crispus L.) is an invasive aquatic plant present across the United States that causes significant recreational issues, outcompetes native plant species, and depletes water quality. Before senescing in mid-summer, curlyleaf pondweed forms a large number of turions that can lay dormant in the sediment for several years. Typical herbicide management of this species occurs in early spring to target the plant before turion production occurs and while native plants are dormant. Flumioxazin has shown potential in curlyleaf pondweed management in small scale studies, but its effects have not been assessed in operational management. In this study, treatments …

Designing Ai Systems To Support A Productive-Failure-Based Learning: Insights From Adult Learners On Ai Applications And Ai System Design Principles, Jinhee Kim, Xi Lin, Seongryeong Yu, Rita Detrick

STEMPS Faculty Publications

Emerging capabilities of generative artificial intelligence (GenAI) offer significant potential to support productive failure (PF)-based learning, which engages adult learners (ALs) in exploring problems before instruction and learning from their initial attempts. However, the effective use of AI to support multifaceted areas of PF-based learning, including problem generation, exploration, consolidation, and knowledge assembly, is limited. Furthermore, AI design principles to support PF-based learning remain under-researched. This study, therefore, aims to investigate ALs’ perceptions of AI applications in enhancing PF-based learning and to explore the essential design principles of AI systems for PF-based learning. To achieve these aims, the study conducted …

Preliminary Analysis Of The Spatial Distribution Of Microplastics Along The Cuyahoga River, Northeast, Ohio, Ella Pitz

Williams Honors College, Honors Research Projects

Plastics are nearly ubiquitous throughout modern society, and when left in the natural environment, they degrade into microplastics. Microplastics are particles that range in diameter from 5 millimeters down to nanometers, and microplastics pose many potential environmental and health risks due to their small size and ease of ingestion. While the study of microplastics in the environment has become more common over the past ten years, microplastic concentrations remain unexplored in many regions throughout the country. Here I present a method for separating microplastics from organic matter and clastic sediment as well as preliminary measurements of microplastic concentrations in sediment …

Modeling Housing Prices: Which Features Matter Most?, Alex Ruvolo

Williams Honors College, Honors Research Projects

This paper attempts to find the biggest factors and traits that influence the cost of housing. This will include the lot size, type of street, utilities, neighborhood, year built, heating, electrical, yard size, number of different rooms, age, condition, and others. I will attempt to answer the question of whether the prices of houses have changed within the last 5 to 10 years, and obviously this is an easy question to answer. However, the bigger question beyond this is are the main factors affecting housing prices all important in explaining this relationship? Is one factor more important than the rest …

Arrangements Of N Planes Resulting In One Bounded Tetrahedral Chamber, Ava Knight

Williams Honors College, Honors Research Projects

This paper investigates the combinatorial geometry of plane arrangements in three-dimensional space, focusing on configurations that produce exactly one bounded tetrahedral chamber. We define T(n) as the number of face-combinatorial equivalence classes of arrangements of n planes in ℝ³ containing exactly one bounded tetrahedral chamber. Known values — T(3) = 0, T(4) = 1, and T(5) = 2 — are established through direct construction, while T(6) remains an open problem. This paper contributes experimental evidence toward resolving T(6) by systematically extending the two valid 5-plane arrangements and verifying, through a plane removal argument, that each yields a valid plane configuration …

Catalan And Hyper-Catalan Numbers: Combinatorial Applications To Polynomial Equations, Leilani Natale

Williams Honors College, Honors Research Projects

In this paper, we study Catalan numbers and their generalization, hyper-Catalan numbers, and explore how these sequences arise naturally in the context of solving polynomial equations using infinite power series. We begin by introducing the Catalan numbers through their combinatorial interpretation as triangulations of convex polygons. Using this geometric definition, we derive a relation whose recursive structure leads to a quadratic functional equation. Interpreting this relation as a formal power series equation allows us to express solutions to quadratic equations as infinite power series whose coefficients are given by the Catalan numbers. This framework is then extended by allowing polygon …

From Touchbacks To Touchdowns: Analyzing The Impact Of The Nfl's New Kickoff Rule Changes, Joshua A. Klatt

Williams Honors College, Honors Research Projects

My proposal analyzes the impact of the NFL's new dynamic kickoff rule changes that were implemented in the Fall of 2024. I use a two-way fixed effects differences-in-differences model using FBS collegiate Division 1 football teams as the control group, and NFL teams as the treatment group. Three of the most important outcome variables I analyze are touchdowns per kickoff return, average yards per kickoff return, and the number of kickoff returns per game.

Identification Of Modified Polymer End Groups For Correlations To Physical Properties, Tj Sacco

Williams Honors College, Honors Research Projects

Plastic has become the primary material for containers in both industrial and commercial fields. Plastics are the optimal choice since they have many physical properties that make them ideal candidates: durability, heat resistance, chemical stability, as well as their inexpensive production cost. Nowadays, the desire for more versatile plastics with strength, flexibility, hydrophobicity, and biodegradability has grown; however, concerns for plastic use have started to rise as well. The overuse of plastics poses a threat to the environment and people’s health: plastics are hard to break down completely which results in the formation of micro(nano)plastics (MNPs). In attempts to circumvent …

Perceptions Of Prek-Eighth Grade School And District Administrators On The English Language Learner Reclassification Criteria, Impacting Long-Term English Learners, Elma Adelina Rodriguez

Doctor of Education (EdD)

The purpose of this study is to examine the perceptions of school and district administrators regarding English Language Learner (ELL) criteria that affect the academic trajectories of Long-Term English Learners (LTELs). ELL criteria differ across states and are used to demonstrate not only English language proficiency but also ELL students' academic performance. While English-only students are not required to demonstrate their academic use of English, ELL students are required to demonstrate English-language academic reading, writing, listening, and speaking skills to be reclassified as English proficient. If ELL students remain classified as ELL for multiple years, they are labeled as LTEL. …

15-Last Lecture, Heinrich Blücher

Bazelow Transcripts

Heinrich Blücher’s Last Lecture, transcript edited by Alexander Bazelow, presents a sweeping philosophical reflection on meaning, freedom, nihilism, and the unfinished task of humanity. Confronting the modern experience of meaninglessness—especially among the young—Blücher argues that philosophy’s enduring task is the transformation of life into meaningful existence through conscious thought and responsible action. He traces the historical development of nihilism and metaphysical belief from ancient myth, through Greek philosophy, Christianity, and modern systems culminating in Hegel, Marx, Kierkegaard, and Nietzsche, whom he treats as prophetic figures of the modern crisis. Blücher criticizes the deification of history, science, power, and ideology, insisting …

Novel Abietane Derivatives: Evaluation Of Therapeutic Potential Against Triple Negative Breast Cancer, Sydney Lawson, Fatima Rivas

Distinguished Undergraduate Researcher Program

Of the estimated 2.3 million women globally who will be diagnosed with breast cancer this year, nearly 25% will be diagnosed with the triple negative breast cancer (TNBC) subtype. Because TNBC lacks specific targets present in other breast cancers, conventional selective treatments are ineffective making TNBC more difficult to treat. TNBC is the most lethal subtype of breast cancer in women and causes approximately 150,000 deaths annually, highlighting the critical need for effective therapeutics. Therefore, our aim is to identify new potential therapeutic agents for TNBC.

The abietane natural product family is a group of tricyclic diterpenoids which have been …
