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 …

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 …


Ceramics And Trade In Mesoamerica: Identity And Resistance In The Maya Culture, Mason A. Swanson Jan 2026

Ceramics And Trade In Mesoamerica: Identity And Resistance In The Maya Culture, Mason A. Swanson

Williams Honors College, Honors Research Projects

The region of Mesoamerica has been researched extensively by archaeologists over the past decades. There are numerous cultures and civilizations that occupied Mesoamerica over thousands of years. This paper will focus on the Maya, one of the most researched and examined of the cultures of Mesoamerica. By examining the ceramics and trade of the Maya one can reconstruct how the Maya identity was viewed in the past. Often the Maya are suggested to have experienced a collapse at the end of the Classic period around (AD 900). This, however, is an oversimplification of the events that occurred. The goal of …


Catalan And Hyper-Catalan Numbers: Combinatorial Applications To Polynomial Equations, Leilani Natale Jan 2026

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 …


Moving Positively: A Review Of Positive Psychology Interventions In Counseling, Spencer M. Fleming, Ingrid Weigold Ph. D Jan 2026

Moving Positively: A Review Of Positive Psychology Interventions In Counseling, Spencer M. Fleming, Ingrid Weigold Ph. D

Williams Honors College, Honors Research Projects

Positive psychology is a relatively new and developing subfield of psychology which examines the machinations and roles of various character strengths and traits such as growth, well-being, meaning, life satisfaction, character strengths, and more. Positive psychology holds various implications for counseling, therapy, individual growth, and self-determination. However, current literature on positive psychology interventions (PPIs) are scattered, nuanced, and lack overall consensus. Thus, encompassing research is necessary to identify common trends, areas for improvement, and a clear direction moving forward. The present review analyzes positive psychology interventions (PPIs) within psychology and counseling. This review examined forty-eight articles, including fifteen meta-analyses, on …


Presidential Slaves: The Story Of Black People In The Lives Of Antebellum U.S. Presidents, Nika Davis Jan 2026

Presidential Slaves: The Story Of Black People In The Lives Of Antebellum U.S. Presidents, Nika Davis

History Dissertations

The historical narrative about American slavery included many topics such as the African slave trade, the Middle Passage, slave culture, rebellions, religion, and abolition.  This study revealed more information to be examined in the record of American slavery relating to the presidents of the United States and their enslaved laborers.  This oversight proved prevalent during the years leading to the American Civil War from 1820-1860.  Therefore, this dissertation focused upon the enslaved and free Black people who intersected with the presidents and their friends, political acquaintances, and family.  By studying their lives, this dissertation revealed that the slaves associated with …


Finding, Founding, And Forging: Queer Formulations Of Family In Nineteenth-Century British Novels, Brian Hicks Jan 2026

Finding, Founding, And Forging: Queer Formulations Of Family In Nineteenth-Century British Novels, Brian Hicks

Theses and Dissertations

This dissertation examines how nineteenth-century British novels imagine and negotiate queer formulations of family at moments when biological kinship, marriage, and inheritance were increasingly formalized as social and legal imperatives. Reading canonical texts by Austen, Shelley, Wilde, Brontë, and Hardy, alongside the proto-modern and modernist work of Joseph Conrad and Virginia Woolf, I argue that these novels resist consanguinity as the sole basis of family and instead theorize queer kinship as something found, founded, or forged through affinity, care, and shared orientation rather than blood or reproduction. Drawing on queer theory, feminist criticism, phenomenology, and Foucauldian accounts of power and …

Will It Tear? Creating A Collegiate Athlete Cutting Mechanics Grading Process, Abigail Savoy, Matthew Morgan, Nicholas Totaro

Distinguished Undergraduate Researcher Program

Collegiate athletes push their bodies to compete at the top level of their sport. Through 5 years, collegiate athletes had 729 ACL tears. To aid in training and the reduction of injury risk, there are several procedures for grading the ability of an athlete to make a cut or change-of direction motion. Through this research project, we defined a procedure for analyzing motion capture video and data of the cutting mechanics of collegiate athletes. This was done to identify which athletes have a higher or lower risk of an ACL injury by comparing knee valgus and other biomechanical indicators on …


Characterizing The Role Off The Sp1/Klf Transcription Factor Huckebein In The Drosophila Melanogaster Ventral Nerve Cord, Benjamin Almond Jan 2026

Characterizing The Role Off The Sp1/Klf Transcription Factor Huckebein In The Drosophila Melanogaster Ventral Nerve Cord, Benjamin Almond

Distinguished Undergraduate Researcher Program

Over the course of embryonic development, the ectodermal cell layer gives rise to a vast array of neurons and glia patterned across the central nervous system (CNS). Neurulation and specification is achieved in the ectoderm through temporospatial patterns of transcription factor (TF) expression, many of which are conserved across evolutionary history. These conserved regulatory motifs allow the use of Drosophila melanogaster to study the mechanisms of neurodevelopment across the animal kingdom. The huckebein (hkb) gene encodes a conserved SP1/KLF TF known to play important roles in cell cycle regulation, tissue morphogenesis during tubular organ development, and gut specification in Drosophila. …

Physiological Leptin Replacement Does Not Reverse Metabolic Adaptations To Starvation In Sprague Dawley Rats, Sydney Junot, Layla Deprimo, Camille Meaux, Arline Narez, David Mcdougal Jan 2026

Physiological Leptin Replacement Does Not Reverse Metabolic Adaptations To Starvation In Sprague Dawley Rats, Sydney Junot, Layla Deprimo, Camille Meaux, Arline Narez, David Mcdougal

Distinguished Undergraduate Researcher Program

Historically, low insulin levels were the signaling event considered responsible for metabolic adaptations to starvation, such as increased sympathetic outflow and increased serum levels of ketones, glucagon, and free fatty acids. Leptin, a hormone produced by adipose tissue, is known to decrease in response to caloric restriction. Recent work in the field suggested that leptin infusion in the final hours of a 48-hour fast reversed all metabolic adaptations to starvation, thus raising questions about an underappreciated role of leptin in the starvation response. This study tested whether physiological leptin replacement, maintaining fed plasma leptin concentrations, during a 72-hour fast in …


Passing In Plain Sight: Visibility, Activism, And Identity, Rei Zimmerman Jan 2026

Passing In Plain Sight: Visibility, Activism, And Identity, Rei Zimmerman

Distinguished Undergraduate Researcher Program

The act of passing would seem to be the opposite of activism because it is an act meant to avoid detection. While the language of passing is, itself, problematic, African-descended people passing as white might be read as attempting to capitulate to a racial binary. Similarly, trans people passing as cis or cishet might be read as attempting to capitulate to the gender binary rather than challenging it. But this paper explores the potential for reading passing as a surprising act of activism that foregrounds resistance, resilience, and solidarity rather than disappearance. I focus on Leslie Feinberg’s groundbreaking trans novel …


Developing A Comparative Framework For Organic Matter Loss Using Standardized Soils To Mimic Urbanized Areas, Madison Woodson, Michael (M.P.) Hayes Jan 2026

Developing A Comparative Framework For Organic Matter Loss Using Standardized Soils To Mimic Urbanized Areas, Madison Woodson, Michael (M.P.) Hayes

Distinguished Undergraduate Researcher Program

Rapid urbanization is an ongoing challenge to the natural ecosystem across Louisiana as the state invests in development to accommodate the challenges of flooding in nearby towns and cities. Across Louisiana waterways, flooding from urban developments along with coastal subsidence and relative sea level rise increase the transport of complex organic matter into local water channels. These events lead to higher concentrations of nutrients, specifically bioavailable carbon which can be lost from breakdown of soil organic matter in water. To better understand and predict organic matter transportation due to flooding events caused by urbanization, we studied the availability of organic …

Impacts Of Real Microplastic Leachates On The Development And Behavior Of Developing Zebrafish (Danio Rerio), Emma Tsai, Melanie Wilson, Mohamed Ateia, Ahmed Abdelmoneim Jan 2026

Impacts Of Real Microplastic Leachates On The Development And Behavior Of Developing Zebrafish (Danio Rerio), Emma Tsai, Melanie Wilson, Mohamed Ateia, Ahmed Abdelmoneim

Distinguished Undergraduate Researcher Program

Plastic pollution in aquatic environments has increased, raising concerns about the toxicity of microplastics (MPs) and their additives to developing organisms. Additives from the MPs can desorb into the surrounding environment, generating leachates that may impact early development. This study evaluated the effects of early developmental exposure to MP leachates on early developing zebrafish (Danio rerio), quantifying effects on larval survival, development, activity, and behavioral responses to acute stressors. MPs—acrylonitrile butadiene styrene (ABS), polyethylene terephthalate (PET), polyamide 66 (PA66), and reinforced glass fiber (MIX)—were processed into particles (< 500 µm) and incubated in embryo media for 24 hours under UV-C, 35 °C, and agitation to generate leachates. Zebrafish embryos were exposed from 6 to 120 hours post-fertilization (hpf) to varying leachate dilutions (corresponding to 0.063 to 10,000 mg MPs/L). At 120 hpf, larvae were assessed for survival, prevalence of morphological defects, overall growth, baseline activity, and behavioral responses to acoustic, visual, and peripheral irritant stressors. MIX leachate significantly increased mortality, while PET leachate exposure reduced growth. No significant morphological defects were observed across treatments. ABS, PA66, and PET leachates altered larval activity and behavioral stress responses. These preliminary findings suggest that MP leachates pose varying developmental and behavioral risks to developing organisms at critical exposure concentrations. Understanding these risks is crucial for assessing the environmental impact of MPs pollution and informing regulatory policies.


Anxiety Disorders Do Not Modulate Performance Monitoring During Visuomotor Learning, Olivia Perry, Leo Barzi, Kaylie Grimm, Leah Charles, Christopher Hill Jan 2026

Anxiety Disorders Do Not Modulate Performance Monitoring During Visuomotor Learning, Olivia Perry, Leo Barzi, Kaylie Grimm, Leah Charles, Christopher Hill

Distinguished Undergraduate Researcher Program

Humans experience different levels of anxiety throughout their daily lives. Some individuals even experience chronic, unprovoked anxiety that leads to a diagnosis of a psychological disorder known as generalized anxiety disorder. Many neurological diseases develop anxiety as a comorbidity and hinder therapeutic interventions. However, we don’t understand how anxiety disorders may affect the development and learning of new motor skills. Thus, the purpose of this study is to evaluate how different levels of anxiety may affect your ability to learn a new skill. We recruited physically healthy, right-handed young adults with and without a diagnosis of an anxiety disorder. Participants …

Bayou Bride: Combining Alligator Leather And Digital Textile Printing In Bridalwear, Martha Rigney, Casey Stannard

Distinguished Undergraduate Researcher Program

Alligator leather is attractive to luxury consumers because of its unique texture and beauty. However, due to the shape of alligator hides, differing scale patterns, and the hardness of the leather, it is less appealing for usage in apparel. One strategy to retain the visual appeal of alligator leather while improving comfort and versatility is to create photo-realistic digitally printed “alligator” textiles alongside real leather. Discovering new ways to use alligators is crucial to the alligator industry, which is experiencing a price slump. This project focused on the bridal market; the utilization of sublimation dye printing allowed me to experiment …


Feelings And Futures: Social Design Addressing Identity And Engagement Of Adolescent Girls In A Community-Based Organization, Eseoghene Mukoro Jan 2026

Feelings And Futures: Social Design Addressing Identity And Engagement Of Adolescent Girls In A Community-Based Organization, Eseoghene Mukoro

Distinguished Undergraduate Researcher Program

Community organizations can provide numerous benefits to adolescent youth in various aspects of their lives—socially, psychologically, and physically, to name a few. Unfortunately, many youth-serving organizations aim to serve youth without directly involving their perspectives in the creation of their respective programs. At the Gardere Initiative, adolescent girls appear to have low levels of engagement and belonging, while their male counterparts enjoy activities and spaces catered to them. This poses a question of how this community organization might better serve the desires and life context of these adolescent girls.
Social Design is the practice of designing an intervention (product, service, …

The Healing Power Of Nanoparticles: Bioengineering Gelatin Films With Lignin-Graft-Plga Nanoparticles For Enhanced Tissue Repair, Marie Howe, Cristina Sabliov, Thanida Chuacharoen, Willyam Nikiema

Distinguished Undergraduate Researcher Program

Fish gelatin, a biocompatible material, can be methacrylated to enable its photo-crosslinking and formation of hydrogels for tissue-repair applications (1). This study investigated the incorporation of lignin-grafted PLGA nanoparticles (LNPs) into 3D-printed fGelMA hydrogels as controlled drug delivery systems. Lignin has UV absorbing properties, which could potentially interfere with photocrosslinking of fGelMA (2). These LNPs possess hydrophobic PLGA core and hydrophilic lignin forming the shell providing ample opportunities for delivery of drugs of different chemistries (3). Fluorescent LNPs (FLNPs) were engineered by covalently bonding a fluorophore to the shell prior to nanoparticle synthesis to allow for fluorophore tracking. The understanding …


Motor Planning And Execution During Feeding In Autistic Children, Iresa Lincoln Jan 2026

Motor Planning And Execution During Feeding In Autistic Children, Iresa Lincoln

Distinguished Undergraduate Researcher Program

Autism is one of the most common pediatric developmental disability diagnoses, diagnosed in approximately 1 in 31 children in the U.S. and 1 in 100 children globally. Autism is often characterized by differences in social communication and repetitive patterns of behavior, activities,
or interests; however, prevalence of clinically significant motor differences in autistic individuals is between 50-95%. These motor differences often interfere with activities of daily living and community participation. Research assessing motor control in autism has yielded mixed findings as to whether the motor differences observed in autistic individuals are associated with differences in motor planning or motor execution. …

Evaluation Of Liberty® Herbicide For Zygosity Verification In Transgenic Maize (Zea Mays) Expressing The Bar Gene From Streptomyces Hygroscopicus, Isabel Hau Jan 2026

Evaluation Of Liberty® Herbicide For Zygosity Verification In Transgenic Maize (Zea Mays) Expressing The Bar Gene From Streptomyces Hygroscopicus, Isabel Hau

Distinguished Undergraduate Researcher Program

Maize (Zea mays) is a major global crop cultivated for food and feed. Most commercial varieties grown in the United States contain herbicide-resistant traits to facilitate weed management. One such herbicide trait is Liberty-Link, which contains the bialaphos resistance (bar) gene from Streptomyces hygroscopicus that confers resistance to glufosinate-ammonium, the active
ingredient in Liberty herbicide. This bar gene is also widely used as a selectable marker in plant transformation. In non-transgenic plants, glufosinate-ammonium inhibits plant glutamine synthetase by acting as a glutamate analog, thereby disrupting amino acid biosynthesis and leading
to plant death. In contrast, transgenic plants expressing the bar …


Measuring The Rise And Fall Of Plasma 25-Hydroxyvitamin D Concentrations In Blue-Tongued Skinks (Tiliqua Scincoides) Following Ultraviolet B Exposure And Withdrawal, Ashleigh Godke, Haerin Rhim, M. Graciela Aguilar, Keishla Marrero-Acosta, Mark Mitchell Jan 2026

Measuring The Rise And Fall Of Plasma 25-Hydroxyvitamin D Concentrations In Blue-Tongued Skinks (Tiliqua Scincoides) Following Ultraviolet B Exposure And Withdrawal, Ashleigh Godke, Haerin Rhim, M. Graciela Aguilar, Keishla Marrero-Acosta, Mark Mitchell

Distinguished Undergraduate Researcher Program

Species-specific husbandry guidelines remain limited for blue-tongued skinks (Tiliqua scincoides), especially in relation to ultraviolet B (UVB) lighting and vitamin D requirements. This study aimed to determine whether UVB exposure is necessary for these skinks and how long 25-hydroxyvitamin D (25-OHD) concentrations persist after UVB withdrawal. Eleven adult skinks who had been fed with wet cat food were exposed to 12 or 2 h of UVB per day for four weeks. Plasma 25-OHD concentrations were very low at the baseline, and significantly increased post-UVB in both groups (p < 0.01), with the 12-hour group increasing from baseline concentrations of 18.5 [12.8–20.5] nmol/L to 820 [730–1251.3] nmol/L and the 2-hour group increasing from baseline concentrations of 22 [15.5–22] nmol/L to 635 [401–892.5] nmol/L. Following the discontinuation of UVB exposure, 25-OHD gradually declined and was not significantly different from baseline concentrations at 7 and 4 months for the 12-hour and 2-hour groups, respectively. Dietary vitamin D3 (2.5 IU/g as dry matter basis), provided through wet cat food alone, appeared insufficient to support sustained plasma 25-OHD concentrations. These findings strongly suggest that blue-tongued skinks rely on UVB exposure to increase their 25-OHD concentrations. Moreover, the shorter 2-hour exposure provided a significant rise in 25-OHD concentrations and remained above baseline for 4 months, suggesting the shorter exposure can benefit these animals, while potentially reducing secondary risks associated with UVB exposure.
