From Resume To Risk Factor: The Connections Between Occupation, Chronic Disease, And Mental Health In The United States, Nemo Thomas, Joshua Dumond, Nicole Real

Undergraduate Student Symposium

Mental health affects various aspects of overall health, including physical, emotional, and social well-being, which influences behavior and management of disease. Furthermore, occupational types (blue-collar, white-collar, and grey-collar) can influence how individuals manage stress. This can be due to the various responsibilities an individual has or the work environment that one is consistently exposed to, which can lead to detrimental mental health outcomes. This study examined the relationship between occupational type and the occurrence of individuals' self-reported levels of distress, anxiety, hopelessness, restlessness, sadness, and worthlessness. The data from this study was obtained from the IPUMS NHIS 2024 surveys, a …

Psychological Separation As A Developmental Moderator Of Cognitive Maladjustment, Tanvi Rudrangi, Kaleigh Cummings, Misha Patel

Undergraduate Student Symposium

Developing a personal identity is a central task of late adolescence (Erikson, 1968). Emerging adulthood, a developmental period spanning the late teens to mid-twenties, is characterized by increased independence and self-focus, providing opportunities for life skill development and self-understanding. Despite this emphasis on self-focus, emerging adults' psychosocial adjustment remains closely tied to parent relationships, particularly the process of separation-individuation from parents. The present study examined whether paternal psychological separation moderates the relationship between self-focused life perspectives and maladaptive cognitions of ego inflation/superiority. Participants included 95 emerging adults (ages 18-25, M=20.7, 60 women). Paternal separation was assessed using the 69-item Psychological …

Undergraduate Student Symposium

Cerebral amyloid angiopathy (CAA) is a common cerebrovascular disease characterized by beta-amyloid (Aβ) accumulation in the cerebral vasculature, resulting in vascular cognitive impairment and dementia (VCID) along with other neuropathologies such as inflammation. Given that medications approved to treat CAA currently do not exist, this highlights that there is a pressing need for more innovative approaches to drug discovery. In this study, classical renin-angiotensin system (RAS)-inhibiting antihypertensive drugs were repurposed to investigate their efficacy for mitigating CAA-associated neuropathology and cognitive decline, while additionally evaluating for sex-specific outcomes. Male and female Tg-SwDI mice were treated for 4 months with non-hypotensive doses …

The Functional Movement Screening In Collegiate Soccer Players, Sophia White, Karina Manrique

Undergraduate Student Symposium

About 70% of soccer injuries are non-contact, resulting from underlying mobility, stability, or movement pattern issues. Soccer players are particularly susceptible to ankle, knee, and hip injuries due to the high demands on lower body mobility, stability and repetitive dynamic motions. Functional Movement Screening is a popular evaluation method that is used to find asymmetries and dysfunctional movement patterns that could put athletes at risk for injury. Scores from the FMS test have been linked to injury risks. The purpose of this study is to conduct and evaluate the FMS performances among collegiate soccer players (n=26) to decrease injury risk, …

Evaluting Practical Limitations Of Signal Detection Theory In Clinical Behavioral Research, Xinlei Zhang, Prarthana Harikrishnan

Undergraduate Student Symposium

Deficits in inhibitory control - the ability to suppress automatic, impulsive responses - has been widely considered as a potential biomarker for mental health disorders. Signal Detection Theory (SDT) has provided a systematic measurement method for inhibitory control in clinical behavioral assessment. To evaluate the feasibility of inhibitory control as a biomarker, researchers have used meta-analysis to examine its effect size (Hedge's g) in differentiating between individuals with mental health disorders and healthy controls. Values of g>0.8 indicate that inhibitory control may serve as a clinically useful biomarker for distinguishing patients from healthy individuals, whereas g<0.8 suggests limited clinical utility. However, our study found that a limitation of SDT - its lack of reliability when participants show perfect performance - would lead to distorted and misleading results when evaluating the efficacy of inhibitory control as a biomarker. In our computational simulation, we found that when applying SDT to a clinically useful biomarker (for example, true effect size g = …

Effects Of Invasive Water Hyacinth On Boldness And Habitat Preference In Mosquitofish, Nicolas Borca, Chancellor Rockwell Marks

Undergraduate Student Symposium

Eastern mosquitofish (Gambusia holbrooki) are small freshwater fish that play an important role in aquatic food webs. Their behavior, especially boldness and risk-taking, can change depending on the type of habitat they occupy. In this study, we investigated how mosquitofish respond behaviorally to the presence of the floating invasive plant water hyacinth by comparing their boldness, preference for cover, and predation rates between water hyacinth and its native competitor, pennywort. Fish boldness was measured using a two-factor latency experiment. Fish were collected from freshwater locations in South Florida that either had the invasive plant or were free of …

We investigated the influence of training and player position on joint power composition among players training for the National Football League draft. Forty-eight draft-eligible players performed pre- and post-training camp running trials at 23.4 km/h. We used motion capture software and MATLAB to calculate bilateral peak hip, knee, and ankle joint power. Compositional data analysis (CoDA) was used, in which positive/generated and negative/absorbed power compositions were expressed as isometric log-rations: hip versus knee + …

Perceived Family Influences On Sexual Decision-Making Among Emerging Adults, Hassan Gowani, Mariana Santiago-Lopez

Undergraduate Student Symposium

Research on familial influences on sexual decision-making has focused primarily on adolescents, resulting in limited understanding of how family relationships may influence emerging adults' sexual decision-making. To fill this gap in the literature, we asked participants (ages 18-29) to indicate yes/no to "Do you think that your family has played a role in your current decision to be or not to be sexually active?" and then provide qualitative responses to "Please elaborate on why you think your family has or hasn't played a role in your current decision to be or not to be sexually active." Based on preliminary analysis, …

Time-Lapse Microscopy To Characterize Astrocyte Precursor Cells Migration Using A Double Reporter Mouse Line, Megan Hilliard, Sravika Chirla, Maria Ramirez

Undergraduate Student Symposium

Astrocytes, the most abundant non-neuronal cell type in the brain, are a diverse population of cells that play a central role in regulating synaptic activity, supporting neuronal energy demands, and modulating interactions among neurons, glia, and blood vessels. Astrocytes originate from astrocyte precursor cells (APCs) in the subventricular zone, from where they migrate to the cortex postnatally. Once in the cortex, APCs continue to proliferate and then undergo morphological and functional maturation. Using a double reporter mouse line engineered to express enhanced green fluorescent protein (eGFP) under the control of the entire glutamate transporter 1 (GLT1) gene and tdTomato (tdT) …

Acute Effects Of D- And L-Beta-Hydroxybutyrate On Vigilance (Sustained Attention And Reaction Speed) In Healthy Adults: A Randomized, Double-Blind, Placebo-Controlled Trial, Catherine Holen

Undergraduate Student Symposium

Exogenous beta-hydroxybutyrate (BHB) supplements are increasingly promoted for cognitive and performance benefits but controlled human data--particularly comparing BHB isomers--remains sparse. This study evaluated whether a low dose, acute ingestion of D-BHB or L-BHB influences vigilance (sustained attention, reaction speed) and fine motor control in fasted, non-keto-adapted healthy adults. A total of 136 participants (20.5 ± 1.4 years; 70.2 ± 15.6 kg) were randomized into three groups: D-BHB (n = 47), L-BHB (n=46), or placebo (n = 43). Measures included the Psychomotor Vigilance Test (PVT reaction time) and the central nervous system tap test. Assessments were conducted at baseline and 60 …

The Effect Of Verbal Encouragement With Swearing On High Intensity Exercise Performance, Ella Kern

Undergraduate Student Symposium

Verbal encouragement has not been shown to reliably enhance performance on the Wingate Anaerobic Test (WAnT); however, research has found that when individuals swear during the WAnT, average power increases. This study examined whether incorporating swearing into verbal encouragement during a WAnT enhances performance, self-confidence, and psychological flow compared to standard verbal encouragement without swearing. Forty-one physically active participants (25 females, 16 males; age 20.8 ± 0.78 years) completed two counterbalanced laboratory visits involving verbal encouragement with swearing (VES) and without swearing (VE) while performing the WAnT on a Wattbike Air ergometer. Average power, fatigue index, self-confidence, and psychological flow …

Does A Competitive Season Alter Elastic Bounce Mechanics In University Distance Runners?, Marcus Marek Tortorella

Undergraduate Student Symposium

The spring-mass model (SMM) describes the body's center of mass oscillation during running as a bouncing system, where energy is absorbed and released, producing two asymmetries that represent muscle-tendon elastic function: (1) landing-takeoff (LTO; % relative difference propulsion to braking time), and (2) rebound (REB; % relative difference effective aerial to contact time). Additional SMM-derived variables, such as vertical stiffness(kvert) and step frequency (SF) may provide insight into the influence of a competitive season on running elastic bounce mechanics in university distance runners. The purpose of this study was to examine the impact of a competitive cross-country season …

Genetic Diversity Of Invasive Grey-Headed Swamphens In Florida Compared To Native Gallinules, Monica Maurer

The grey-headed swamphen (Porphyrio poliocephalus), established in southeast Florida since 1996, continues to expand into the northern Everglades and Lake Okeechobee despite prior eradication attempts. This study is comparing the genetic diversity of invasive grey-headed swamphens to the genetic diversity of native purple (P. martinica) and common (Gallinula galeata) gallinules to better understand invasion history, competitive potential, and ecosystem impacts. Muscle tissue samples of P. porphyrio collected by the Florida Museum of Natural History from 1999-2023 and the Florida Fish and Wildlife Conservation Commission (FWC) …

Developing A Novel Protocol To Isolate Mitochondria From The Cnidarian Aiptasia Pallida For Bioenergetic Studies , Chelsea Nguyen, Kiran Sajnani

Undergraduate Student Symposium

The symbiotic relationship between cnidarian hosts and photosynthetic dinoflagellates relies on a dynamic exchange of metabolites between key organelles including chloroplasts and mitochondria. Understanding how temperature affects this exchange is pivotal to determine its role in metabolic dysbiosis, but methodological challenges in isolating mitochondria from cnidarian tissue must be addressed. The aim of this project is to develop a reproducible homogenization and isolation protocol of mitochondria from the upside-down sea jelly Cassiopea xamachana, to be used as a model for subsequent bioenergetic studies. Mesogleal tissue from laboratory acclimated C. xamachana was finely minced, and several mechanical homogenization methods were …

Passion Versus Predisposition: How Engagement, Personality, And Trait-Anxiety Predict Homesickness, Bala Sivani Padala, Porsha Adoghe, Alyssa Harris

Undergraduate Student Symposium

Homesickness is a prevalent condition affecting many college students. Several factors contribute to homesickness, including, but not limited to, adjustment difficulty, missing family and friends, rumination, and loneliness. To better understand homesickness, we explored how engagement, anxiety, and personality moderate each factor. Engagement and personality were hypothesized to negatively correlate with homesickness. Trait anxiety was hypothesized to positively correlate with homesickness. We examined these variables by having participants complete a Google form that included questions from four surveys: the Utrecht Homesickness Scale (UHS), the National Survey of Student Engagement (NSSE), the State-Trait Anxiety Inventory (STAI), and the Ten-Item Personality Inventory …

Biomechanical Stress And Asymmetrical Loading: Comparing Unilateral Landings Across Volleyball Hitter Positions, Nihar Patel

Undergraduate Student Symposium

Jump-based movements in volleyball, particularly unilateral landings, generate substantial injury risk to the anterior cruciate ligament (ACL). These landings create asymmetrical ground reaction forces and patellar joint instability, with outside and right-side hitters most affected since they often land on a single leg after spiking. Prior studies show that unilateral landings produce higher peak forces and reduced knee flexion compared to bilateral landings, increasing biomechanical stress. Lead-limb dominance and player position further influence landing mechanics and loading patterns. Using VERT, a wearable sensor that records jump height, frequency, and landing impact, along with synchronized video analysis, this study compares landing …

This project developed a data science approach to build a structured database that consolidates evidence of glyphosate exposure and neurological health outcomes, with a primary focus on the United States. A systematic search of scientific databases identified over seventy peer-reviewed studies, primarily U.S.-based with some global representation. Data for six primary health outcomes (depression, anxiety, reported suicide, ADHD, Parkinson's disease, and Alzheimer's disease) were extracted. Each study was reviewed for design type, study location, exposure assessment methods, health …

Repurposing Nilotinib In A Metabolically Compromised Mouse Model Of Alzheimer's Disease, Maria Ramirez Aleman, Victoria Pullido-Correa, Ariana Hernandez, Chana Vogel, Ana Carvalho, Daniel Lopez, Esperanza Barrios, Katilin Martin, Dylan Kuni, Maria A. Paiz

Undergraduate Student Symposium

Diet-related metabolic disorders, including obesity, prediabetes, and type 2 diabetes, significantly increase the risk of Alzheimer's disease (AD). Despite substantial research, effective disease-modifying therapies remain limited. Nilotinib, a tyrosine kinase inhibitor approved for leukemia, has shown neuroprotective effects in preclinical AD models, including reduced amyloid-β pathology and improved cognition. In vitro studies also suggest nilotinib enhances mitochondrial bioenergetics. However, its efficacy under conditions of metabolic dysfunction remains unclear. This study therefore evaluated the effects of nilotinib in an AD mouse model with diet-induced metabolic impairment. Male and female B6129SF1/J control and 3xTg-AD mice were fed a low-fat (LFD) or high-fat …

Temperature-Driven Changes In Lysis Kinetics Of Bacteriophages Infecting Gordonia Rubripertincta, Bianca Gonzalez, Jyothi Vivekananda

Undergraduate Student Symposium

Antibiotic resistance represents a significant global health crisis creating a necessity for alternative treatments to combat drug-resistant pathogens. One alternative treatment is bacteriophages, such as those targeting Gordonia rubripertincta, a gram-positive, aerobic actinomycete bacterium which has shown intrinsic resistance to some antibiotics. Furthermore, G. rubripertincta can cause endocarditis and CNS infections in immunocompromised individuals. Phages that successfully target G. rubripertincta (Alyssamiracle, Fribs8, Genamy16, and NovaSharks) have been discovered by NSU students. The phages work in a lytic manner, bursting the bacteria and releasing its viral progeny. The goal of this research was to evaluate the lysis kinetics of these …

Training Language Models For Bilateral Trade With Private Information, Dirk Bergemann, Soheil Ghili, Xinyang Hu, Chuanhao Li, Zhuoran Yang

Cowles Foundation Discussion Papers

Bilateral bargaining under incomplete information provides a controlled testbed for evaluating large language model (LLM) agent capabilities. Bilateral trade demands individual rationality, strategic surplus maximization, and cooperation to realize gains from trade. We develop a structured bargaining environment in which LLMs negotiate via tool calls within an event-driven simulator, separating binding offers from natural-language messages to enable automated evaluation. The environment serves two purposes: as a benchmark for frontier models and as a training environment for open-weight models via reinforcement learning. In benchmark experiments, a round-robin tournament among five frontier models (15,000 negotiations) reveals that effective strategies implement price discrimination …

A Model For Professional Organization Membership Support: Trust, Commitment, Membership Value, And Relationship Quality Commitment, Shawn F. Clouse, Nader H. Shooshtari, Simona Stan, Liz Kohl

AMTP Proceedings 2026

Members of professional associations join these organizations for reasons that include benefits and services to members, advocacy and lobbying on behalf of members and their interests, networking opportunities, and a sense of community and identification with fellow association members. Members are likely to commit to the association and remain as members to the extent they are satisfied with what the association provides and if they perceive the benefits to exceed the costs (not just monetary) of membership. This survey of members of a professional association investigates the relationship between trust, relationship quality commitment, membership dues value and commitment (normative, affective, …

When Faces Do Not Help: Visual Design And Engagement For B2b Technology Brands On Instagram, Ali Jamei, Sima Sabahi

AMTP Proceedings 2026

Firms increasingly use visual content on social media to connect with customers, yet most evidence on what drives engagement comes from consumer or personal contexts. This study examines how simple visual features in Instagram photos posted by B2B technology brands relate to engagement, interpreted through processing fluency. The dataset contains 600 photos from 30 B2B technology brands. For each image, we record likes and comments, collect brand and post level metadata, and use Microsoft Azure computer vision tools to detect faces, classify their age group and gender, and identify the dominant background color.

Transactional Platforms Under Goal Duality: Managing Tensions With Coordination Strategies, Nikolina Koporcic, Vesna Damnjanovic, Johan Frishammar, Vinit Parida

AMTP Proceedings 2026

While traditional transaction platforms like Airbnb emphasize economic value creation, some emerging platforms increasingly strive to pursue both economic and social goals. Balancing these dual goals creates tensions, especially in resource-constrained contexts, requiring innovative coordination strategies. Drawing on collective action theory and platform literature, we investigate how four start-up platforms pursuing dual goals manage these tensions. Using case study data from 64 interviews and extensive secondary sources, we identify six core tensions related to mission, user inclusion, scalability, operational control, community engagement, and stakeholder communication. We demonstrate how three key coordination strategies—framing, convening, and multivocality—help alleviate these tensions. Our study …

Deploying Root-Cause Analysis (Rca) Agents: An Implementation Blueprint For Ai-Augmented Marketing Analytics, Seojoon Oh

AMTP Proceedings 2026

Artificial intelligence is widely adopted in marketing, yet many organizations struggle to translate analytical outputs into timely action. This paper presents a practitioner-oriented blueprint for deploying root-cause analysis (RCA) agents within AI-augmented marketing analytics systems. We propose a three-layer reference architecture—semantic data layer, autonomous RCA agent, and action layer—that enables continuous anomaly detection, causal diagnosis, explanation generation, and recommendation delivery. Through simulated e-commerce use cases, we demonstrate how RCA agents identify performance disruptions such as email engagement declines and checkout failures, and translate diagnostic findings into actionable guidance. Beyond system design, we outline organizational workflows, trust-building validation loops, scalability pathways …
