Mechanisms Driving Disparities In Income Mobility Across The Income Distribution, Joe Larkins

Honors Theses

This study examines intergenerational income persistence across the income distribution, testing whether mechanisms driving inequality differ between families in the top and bottom halves of the income distribution. Using data from the National Education Longitudinal Study of 1988 (NELS:88), a nationally representative longitudinal survey of 8th grade students and their parents, this research estimates an interaction model comparing parental income effects for children in advantaged versus disadvantaged economic circumstances. The analysis reveals that a $1,000 increase in parental income yields eight times greater income gains for children in the bottom half of the distribution compared to those in the top …

Reassessing Argentina’S 2018 Crisis: Fiscal Imbalances, External Constraints, And Imf Policy, Michael Garcia

Honors Theses

This thesis will evaluate the causes of Argentina’s 2018 financial crisis, examining how it should be evaluated through the lens of fiscal imbalance or by external constraints. The dominant interpretation is shown in the International Monetary Fund’s (IMF) 2018 Standby Agreement. It attributed the crisis to excessive fiscal deficits, inflation, and weak monetary discipline. This perspective is supported by the Polak model. The model itself connects domestic credit expansion to balance of payment imbalances. It views external crises resulting from internal policy excess.

This paper offers an alternative interpretation of a post-Keynesian that emphasizes external vulnerability, foreign currency debt, and …

A Mixed-Methods Cross-Cultural Analysis Of Trust, Parenting, And Well-Being Of Emerging Adults In The United States And Romania, Matthew Bucaloiu

Honors Theses

Trust is linked to emerging adults’ higher well-being. To our knowledge, few studies explore U.S. and Romanian emerging adults’ trust in others and their parents and their relationships to dimensions of parenting and well-being. This mixed-methods project examines cross-cultural differences and similarities in the relationships between trust, parenting dimensions, and well-being in two countries. With self-report quantitative data from 152 U.S. and 233 Romanian emerging adults, Study 1 found positive correlations between general trust dimensions, trust in mothers and fathers, parental care, and well-being, while psychological control was negatively correlated with trust and well-being. Multiple regression analyses revealed that for …

Constructing Descriptive Representation: A Study Of Contemporary Political Figures In The United States, Emma Zalewski

Honors Theses

Political representation in the United States depends not only on who the officeholders are, but on how they publicly perform identities such as gender, race, class, religion, and profession in ways that shape trust and legitimacy. Existing work on descriptive representation and performativity explains why shared identities matter, but it often treats identity too much like a fixed demographic category rather than a strategic and audience-sensitive rhetorical practice, leaving the question of how politicians actually deploy identity across different political settings unexplored. This project addresses that gap by showing that identity claims are best understood as deliberate performances that vary …

Un-Determining The Overdetermined Body: Anorexia Nervosa And Selfhood In What I Lost By Alexandra Ballard, Maddalena (Maddy) R. Grieco

Honors Theses

This thesis examines the intersection between young adult fiction and anorexia nervosa through the lens of Alexandra Ballard’s 2017 novel, What I Lost. The fictional space of the novel interacts with the larger trends of American culture and society, forming a connection between the external world and the protagonist’s personal experience with anorexia nervosa. Specifically, this thesis explores three external forces–the fashion industry, the transmission of generational ideals and habits, and the institutional recovery center–that are mapped onto the site of the female body, resulting in the expression of anorexia nervosa. The following chapters detail each external influence, respectively, …

Deep Learning Approaches For Voltammetric Analysis Of Coffee, Ryan Koes

Honors Theses

This thesis investigates deep learning approaches for voltammetric analysis of brewed coffee using a low-cost electrochemical system and screen-printed electrodes (SPEs). Traditional analytical methods, such as high-performance liquid chromatography (HPLC) and gas chromatography-mass spectrometry (GC-MS), provide precise quantification of key compounds but require expensive instrumentation and specialized expertise, limiting accessibility. While SPEs offer a more accessible alternative, they yielded poor results with traditional processing; however, when combined with a neural network, the system proved more effective. In experiments with 132 coffee samples, mean errors for caffeine, CGA, and TDS predictions were 52.98 ppm, 70.48 ppm, and 0.08%, respectively. These findings …

Sedimentology, Paleontology, And Depositional Environments Of The Upper Devonian Lock Haven Formation In West Burlington Quarry, North-Central Pa, Michael Harman

Honors Theses

The Upper Devonian Lock Haven Formation in north-central Pennsylvania preserves evidence of significant climactic and evolutionary transitions, including the fin-to-limb transition and initial arborescence. The formation contains abundant sedimentary features, palynomorphs, trace fossils, and fish body fossils, making it crucial for reconstructing these paleoenvironments. However, integrated studies on the Lock Haven Formation are rare. This study characterizes the depositional environments, ichnology, paleontology, and age of the Lock Haven Formation. A recent exposure at the Insinger-Ward West Burlington Quarry reveals three middle to early late Famennian lithofacies associations (FAs). FA1 consists of red sandstone, shale, and mudstone containing rhizoliths (deeply penetrating …

Origins Of Musical Preferences: Infants' Responses To Sung Vocal Timbre, Hayley Leopold

Honors Theses

Understanding the origins of aesthetic preferences remains an important question in psychology, particularly in domains such as music where both biological constraints and cultural learning play important roles. While adults exhibit consistent preferences for certain musical features, including aspects of vocal quality or timbre, it remains unclear whether these preferences reflect early-developing perceptual biases or emerge through experience. The present study addresses this question by adopting a developmental paradigm previously used in the visual domain to examine whether infants’ responses to music align with adult aesthetic evaluations.

Twenty three infants between 8 and 12 months of age participated in a …

Utilizing Computer Modeling To Optimize Electric Fields Within Xenon Time Projection Chambers, Miles Meloni

Honors Theses

XENONnT is a physics experiment designed with the goal of detecting dark matter particles. The detector is a time projection chamber; a series of charged electrodes creates an electric field, surrounding a central body filled with liquid and gaseous xenon. Photomultiplier tubes (PMTs), positioned on either end of the chamber, serve to detect light signals. We seek to minimize the root mean square of the electric field norms experienced by the PMTs. This quantity corresponds to the variance in the electric field observed by the PMTs. Establishing a consistent electric field is important to maintaining these sensitive components. The electric …

Inequality In The Urban Forest: Modeling Tree Canopy Dynamics Through Demographics And Restoration Strategies, Eve Johansson

Honors Theses

Urban tree canopies play an important role in environmental quality, public health, and neighborhood livability, yet their distribution is highly uneven and often reflects historical patterns of inequality. In Brooklyn, long-term processes such as redlining, uneven development, and demographic change have contributed to persistent disparities in access to green space.

This thesis examines how urban tree canopy evolves across space and time in Brooklyn and how different restoration strategies affect long-run outcomes. The analysis uses demographic and canopy data from 1990-2020, considering race, income, employment, and educational attainment. Among these, education is the most consistent predictor of canopy coverage, with …

A Web-Based Wizard-Of-Oz Platform For Collaborative And Reproducible Human-Robot Interaction Research, Sean O'Connor

Honors Theses

The Wizard-of-Oz (WoZ) technique is widely used in Human-Robot Interaction (HRI) research, but two persistent problems limit its effectiveness: existing tools impose technical barriers that exclude non-engineering domain experts (the Accessibility Problem), and the fragmented landscape of robot-specific implementations makes interaction scripts difficult to port across platforms (the Reproducibility Problem- concerning execution consistency and portability, not third-party replication). Through a literature review, I identified three design principles to address both: a hierarchical specification model, an event-driven execution model, and a plugin architecture that decouples experiment logic from robot-specific implementations. I realized these principles in HRIStudio, an open-source, web-based platform providing …

The Discrepancies In Voter Perception Of Male And Female Political Candidates: Biases Of Characteristic Traits And Policy Priority, Julia Piver

Honors Theses

Gender remains a defining factor in how political candidates are perceived by the American electorate, shaping not only evaluations of characteristic traits but also perceived policy priority. These discrepancies are rooted and propelled by traditional gender roles from the 1900s. This thesis shows that the perceptions of female and male political candidates differ depending on the informational environment as well as the voter demographics. I used both a quantitative nationally representative survey and a qualitative interview of students on Bucknell's campus. The date revealed that individuals in lower information environments are more likely to enact gender stereotypes along traditional gender …

Quantitative Assessment Of Roasted Coffee Freshness Over Time Using Multi-Parameter Analysis, Maya Fetzer

Honors Theses

Roasted coffee undergoes continuous chemical and physical degradation after roasting, yet industry freshness standards remain empirically defined rather than grounded in measurable parameters. This study developed a multi-parameter framework for quantifying roasted coffee freshness by integrating gas-phase and solid-phase analysis, backed by human sensory evaluation, across three roast levels — light (City+), medium (Full City), and dark (Vienna) — over a four-month storage period. CO2 off-gassing was monitored continuously for 30 day, gas chromatography-mass spectrometry (GC-MS) tracked volatile compound changes in headspace gas, and Fourier transform infrared-diffuse reflectance spectroscopy (FTIR-DRIFTS) quantified oxidation-associated functional group changes, and microindentation assessed bean stiffness. …

Barriers To Immunity: Understanding Covid-19 Vaccine Uptake In Africa, Emilia Blechschmidt

Honors Theses

This thesis examines the factors influencing COVID-19 vaccine uptake across African countries, with a focus on structural, informational, and behavioral barriers to immunization. Drawing on cross-country data, the study analyzes how access to transportation, reliable information, and healthcare resources shape vaccination rates, alongside the effect of demographics and institutional factors in shaping individual perceptions of risk and vaccine safety.

The findings emphasize that the broader strength and preparedness of national health systems strongly influence vaccine uptake. Countries that demonstrated higher coverage of routine childhood immunizations, such as polio and hepatitis B, also tended to perform better in COVID-19 uptake efficiency …

Combining Haptic Feedback With Electromyography To Study Knee Injury In Stationary Cycling, Christopher Kirby

Honors Theses

Patellofemoral Pain Syndrome (PFPS) is the most prevalent overuse injury in cycling, often linked to altered neuromuscular activation patterns of the quadriceps and hamstrings. While sensory feedback has successfully modified cyclists posture, there is a critical lack of evidence-based interventions targeting the underlying muscle activation imbalances associated with chronic knee pain. This study aimed to develop and validate a novel, real-time biofeedback system that utilizes electromyography (EMG) to trigger vibrotactile cues, aiming to shift muscle onset timing earlier in the pedal stroke to mitigate PFPS-related imbalances. A closed-loop system was engineered by integrating a Delsys EMG system with a SageMotion …

Interpreting Legal Standards Of Proof: An Experimental Study Of Probabilistic Decision-Making, Hayley Leopold

Honors Theses

Legal standards of proof play a central role in structuring decision-making under uncertainty, yet they are typically communicated using qualitative language rather than precise probabilities. This raises an important question: how do individuals interpret and apply these standards when making decisions based on probabilistic evidence? This study examines whether individuals apply legal standards of proof in a manner consistent with their commonly associated probabilistic thresholds, and whether quantification and incentives improve alignment with normative decision-making.

To address these questions, I conducted a controlled behavioral experiment in which participants made legal-style decisions under uncertainty. Participants were assigned roles in a simplified …

Design And Analysis Of Energy Recovery Methods For Reduced Aircraft Emissions, Joshua C. Hauck

Honors Theses

Aircraft flights are an increasingly popular mode of transportation. However, their harmful impacts on the environment are a growing concern. Many engineers have worked to develop fully electric aircraft to address this issue. Although they are much more sustainable than conventional aircraft, electric aircraft encounter severe limitations imposed by current battery technology. One alternative route engineers have taken is developing energy recovery methods (ERMs). These are marketed as devices that reduce aircraft fuel consumption without significantly changing their structure and functionality, making them an excellent short-term solution. However, there is little to no consideration of the tradeoffs induced by the …

Plea Bargaining And The Destruction Of Procedural Justice: A Theoretical And Empirical Critique Of Fairness In The U.S. Legal Sphere, Emma Scillitani

Honors Theses

This thesis examines the legal process of plea bargaining as it currently operates within the criminal justice system in the United States. Through both an empirical and theoretical evaluation of this procedure, it analyzes how plea bargaining exists in practice and whether it can be considered a fair mechanism of case resolution. This project investigates the practice on a molecular level through its presence at a county-level court jurisdiction, which represents broader structural implications of the national legal system. Furthermore, it identifies three central factors that drive the overutilization of plea bargaining: power asymmetry, information, asymmetry, and case processing time. …

Imagined Afterlives: Anti-Black Medical Violences In Contemporary Black Arts, Katie Schadler

Honors Theses

“Imagined Afterlives: Anti-Black Medical Violences in Contemporary Black Arts” is a multi-genre exploration that studies the following works: Venus (1996) by Suzan Lori Parks, Get Out (2017) by Jordan Peele, and Dawn (1987) by Octavia Butler. I respectively study an experimental play, a psychological horror film, and a speculative novel to understand how Black creatives are depicting and responding to anti-Black violences, particularly medical violences. This work brings together Black art spanning from the late 1980s to 2017 as well as historical events and figures from the eighteenth century all the way to a not-so-distant future. While these works defamiliarize …

Group-Based Integer Factorization: Theory And Performance, Phuong Cao

Honors Theses

Integer factorization, the problem of finding a nontrivial factor of a composite integer N=pq for large primes p,q, particularly at the size of RSA moduli, is a notoriously difficult challenge that takes classical methods such as Trial Division and Fermat’s Algorithm trillions of years to solve. This thesis studies four probabilistic algorithms that exploit algebraic group structures to achieve significantly better, subexponential efficiency for certain classes of N: Pollard’s p-1, Williams’ p+1, Lenstra’s Elliptic Curve Method, and Pell’s Conic Method. In each case, the algorithm operates on a group over ℤ/Nℤ that decomposes, via the Chinese Remainder Theorem, into corresponding …

The Impacts Of Artificial Intelligence Grammar Checkers On The Grammatical Skills Of L2 English Speakers, Tessa Brizhik

Honors Theses

In recent years, generative artificial intelligence (AI) has emerged as a widely accessible tool in academia, upon which students have increasingly come to rely and include in their writing process (Alharbi et al., 2023). Across the field of English second language learning, corrective feedback is widely recognized as a major influence for grammatical development (Lyster & Ranta, 1997). Corrective feedback may function implicitly, explicitly, or as an interaction between both mechanisms. Research suggests that grammatical knowledge may be largely acquired implicitly for adults learning a new language, with explicit learning playing a secondary role (Ivanova et al., 2012, Jackson & …

Investigating Bilingual Language Learning Using Artificial Grammars, Kyla Kelly

Honors Theses

Language development research has established that infants can learn language rapidly and without explicit instruction through implicit learning mechanisms like statistical learning. These mechanisms can be used to learn word boundaries, sounds, meanings, and grammar rules of language. One method for investigating this is artificial grammar learning (AGL), in which people are exposed to sequences of nonwords to see if they can unconsciously learn their underlying grammars. While much of statistical learning and AGL research has focused on a monolingual perspective, most of the world’s population is multilingual. Studies like Weiss, Gerfen, and Mitchel (2009) and Mitchel and Weiss (2010) …

Paleoflood Chronology For The West Branch Of The Susquehanna River Using Abandoned Chute Channel Sediments, Pennsylvania, Usa, Juliette A. Vanluven

Honors Theses

Anthropogenic climate change is altering the hydrologic cycle, increasing flood frequency and severity, with associated increased risks in population exposure. This is associated with increasing risks to the population of the Susquehanna River Valley, which supports over 600,000 people today. However, our understanding of the frequencies of large floods is limited by relatively short instrumental records. By studying sediments from an abandoned chute channel in the Robert Allen Natural Area near Williamsport, PA, we can extend the existing flood records using paleoflood slackwater sediments along the West Branch of the Susquehanna River.  Sylvan Dell is an abandoned chute channel that …

Assessing Relations Between Rape Myth Acceptance, Prior Sexual Victimization, And Bystander Intervention Behavior, Zoe Mendel

Honors Theses

Campus Sexual Assault (CSA) remains a very prevalent issue in higher education (Koss et al., 2022). Through cultural norms, sexual violence is often normalized, with blame frequently shifted away from perpetrators and onto victims. Rape myth acceptance (RMA) contributes to harmful harmful attitudes that justify or minimize sexual violence (Lonsway & Fitzgerald, 1994). Prior research suggests that lower endorsement of rape myths is associated with greater prosocial bystander intervention behavior (McMahon, 2010); however, findings on the role of prior victimization are mixed. This study used a mix-method approach, including a survey and interviews. Results indicated that members of Greek life …

Sedimentological Characterization Of Main And Chute Channel Scroll Bars Along The Kantishna River, Alaska, Cooper Sentz

Honors Theses

Scroll bars, arcuate sediment ridges found along the inner banks of river bends, are common floodplain features in meandering river systems that form during lateral channel migration. Two hypothesized formation mechanisms described in prior studies are the aggradation of suspended load onto abandoned inner bank levee (IBL) deposits during overbank flow and the migration of transverse bar packages from the channel bed up onto the point bar during flooding events. To study the sedimentology and geometry of these features, we conduct remote sensing and field analysis on a 60 km portion of the Kantishna River, AK: a highly sinuous, pro-glacial …

Pursuer Evader Surveillance Game, Zijie Mu

Honors Theses

This thesis studies the pursuer evader surveillance game with a triangular obstacle in the short-term. In the game, the pursuer aims to maintain surveillance of the evader as long as possible while the evader aims to break surveillance in a finite time. We classify the player strategies into  ideal ones and best admissible ones. The outcome of the game is determined by line of sight. We reduce the 4D game to a 3D game with a boundary separating two different local regimes. When the evader starts inside the threshold, we show that there exists an admissible evader that maintains an …

Toggling (De) Legitimization: How Presidential Candidates Framed Israel And Antisemitism On The 2024 Campaign Trail, Kate Chasin

Honors Theses

This study explores how Joe Biden and Donald Trump changed the way they framed Israel and antisemitism in speeches on the 2024 campaign trail, depending on whether they were speaking to a Jewish or non-Jewish audience. 55 speeches were examined, containing language on American-Israeli relations, the Israel-Hamas War, and antisemitism, manually categorized by frame, and compared for rhetorical shifts based on whether the audience was Jewish. When speaking to a Jewish audience about Israel, candidates humanized themselves as a campaign tool. When speaking about antisemitism, candidates used the form of hatred as a campaign tool.

Education And The Maternal Childcare Gap: Evidence From The Uk Covid-19 Pandemic, Lara Bakhaya

Honors Theses

This paper examines whether college education shapes working mothers’ access to remote work, flexible working, and childcare hours in the United Kingdom, and whether COVID-19 school closures amplified these inequalities. Using data from the UK Time Use Survey (2016–2021), a repeated cross-sectional diary dataset spanning the pre-pandemic period and five COVID-19 waves, this paper estimates weighted logistic and ordinary least squares regressions on a sample of married or cohabiting, employed mothers. School closures serve as a natural experiment, providing an exogenous shock to caregiving demands that affected all mothers simultaneously regardless of education level. College education significantly predicted working from …
