Social Health Among Adolescents In The Global School-Based Student Health Survey (Gshs), Luke Pontoriero, Sarah Simon, Lauren Anderson

Seaver College Research And Scholarly Achievement Symposium

Background: Social health is a function of the quantity and quality of relationships, including with family members and peers. Adolescents who report being lonely or having no close friends have a low quantity of relationships, and those who feel that their peers are unkind and their parents are not understanding have low quality relationships. We examined whether poor social health is associated with violent behavior.

Methods: We analyzed data from the Global School-based Student Health Survey (GSHS), which employs a standardized two-stage cluster sampling method and a validated questionnaire to explore health and risk behaviors among nationally representative samples of …

Genome Analysis Of Aeromonas Hydrophila Strain S14-452, Zarin Tasnim Raya

Undergraduate Research Conference

The Aeromonas hydrophila are gram-negative, opportunistic bacteria that can infect many groups of organisms, mainly fish and amphibians. In channel catfish, A. hydrophila causes fatal bacterial septicemia, leading to massive economic losses for catfish farmers. Therefore, an understanding of its genome will aid in identifying its virulence factors, metabolic pathways and survival mechanisms within the host. This study details the draft genome sequence of A. hydrophila strain S14-452, isolated from channel catfish exhibiting bacterial septicemia during a disease outbreak at a catfish farm.

A. hydrophila strain S14-452 was sequenced using the Illumina iSeq 100 System. Assembly was performed with SPAdes, …

Self-Efficacy As A Moderator Of The Effectiveness Of A Sleep Hygiene Intervention, Sabrina Krebs, Nataria Joseph, Janet Trammell

Seaver College Research And Scholarly Achievement Symposium

Interventions that address sleep hygiene knowledge and behaviors have yielded inconclusive results. The aim of the current study was to assess the effectiveness of an online sleep hygiene intervention on modifying sleep hygiene behavior and sleep quality, hypothesizing that the use of a sleep hygiene intervention will be more effective at increasing sleep hygiene behaviors and sleep quality compared to the control. In addition, we hypothesized that self-efficacy may moderate this effect, with the intervention being more effective among those with high levels of self-efficacy compared to those with low levels. Participants included 66 college students (78.3% female). Participants were …

Failure For Avon, Failure For Labour A Waterworks Project And The Shortcomings Of Left-Wing Groups In Pre-Wwi Aberdeen, Garrett Mast

The Thetean: A Student Journal for Scholarly Historical Writing

On September 16th, 1909, the Aberdeen Daily Journal ran a single article that encompassed one and a half pages of the ten- page printing. This article did not discuss any national or international news, but rather a town council meeting for the city of Aberdeen in northern Scotland. This meeting was anything but standard procedure, lasting six and a half hours, a record for the council with at least 27 of the 34 councillors participating in the debate. The debate discussed the rather mundane question of from which river the council should seek approval for pumping new drinking water.1 “The …

Pain For Profit The Motivations Of Slave Surgeons In The Eighteenth To Nineteenth Century Caribbean, Gabe Smock

The Thetean: A Student Journal for Scholarly Historical Writing

When late eighteenth- century British surgeon Dr. Alexander Falconbridge ventured belowdecks to check on the hundreds of slaves chained there, he had no illusions about the horrors of the Middle Passage. After all, this was not his first voyage providing medical care for slaves until they disembarked at the infamous markets of colonial Kingston, Jamaica. He took a moment to brace himself, then ventured down into the damp air below only to encounter a sight so awful that it was difficult to put into words when he recounted the experience years later to Parliament. As a consequence of being packed …

Psilocybin Impairs The Extinction Of Contextual Fear In Adult Female, But Not Male, Rats, Lillianna P. Puppel, Aleece K. Al-Olimat, Kylie M. King, Marisa J. Savini, Claire E. Miller, Colin R. Del Valle, Heather R. Sparkman, Brooke E. Bramlage, Phillip R. Zoladz

ONU Student Research Colloquium

Fear-related disorders are often treated with exposure therapy, a technique based on the concept of extinction. However, this type of therapy is ineffective for many individuals, so finding a pharmacological adjunct that augments the extinction of fear could lead to better treatment outcomes. In recent preclinical work, investigators have shown that psychedelics can accelerate the extinction of fear, potentially through their impact on neurotrophic signaling. We previously found that psilocybin exerted sex-dependent effects on the extinction of conditioned fear to an isolated cue (i.e., a tone). Specifically, psilocybin enhanced the extinction of cue fear in male rats but impaired it …

Cognitive Function And Cardio-Pulmonary Responses Following One Night Sleep Deprivation Among College-Age Students, Jacob S. Kreger, Andrew Schroeder, Michael Ranney

ONU Student Research Colloquium

The relationship between sleep and quality of life has been extensively studied. Previous research suggests that even one night of sleep deprivation negatively impacts cognitive ability and stress levels. In this study, physiological stress markers—heart rate (bpm), blood pressure (systolic, diastolic, mean arterial pressure), respiratory rate (rpm), and oxygen saturation (%)—were measured while participants rested. Cognitive function was assessed using the Stroop color test. Twenty five healthy college students (ages 18-23, male and female) were grouped based on sleep duration (0-4, 4-6, and 7-9 hours), each group consisting of male and females. It was hypothesized that shorter sleep durations would …

Efficacy And Safety Of Concomitant Surgical Ablation During Mitral Valve Replacement: A Systematic Review, Omar Hamodat, Saif Almuzainy, Rand Yahya, Razan Alzaatreh, Samiullah Haroon, Salam Koniali

Journal of the Saudi Heart Association

Objectives: Atrial fibrillation (AF) is a common comorbidity in patients undergoing mitral valve surgery (MVS), significantly increasing the risk of thromboembolism, heart failure, and mortality. Surgical ablation has recently been given a Class IA recommendation for concomitant MVS, reinforcing its role in restoring sinus rhythm and improving outcomes in this population. However, concerns about procedural complexity, extended operative time, and postoperative risks have limited its widespread adoption. This systematic review aims to synthesize evidence from recent randomized controlled trials to evaluate the safety and efficacy of surgical ablation for AF in patients undergoing MVS, addressing critical gaps in current clinical …

The Role Of Urbanization And Corticosterone In Auditory Sensory Processing In House Sparrows (Passer Domesticus), Brooke Fox, Ashley Lauraine, Hannah Peterson

24th Annual A. Paul and Carol C. Schaap Celebration of Undergraduate Research and Creative Activity (2025)

Urban habitat expansion will introduce new anthropogenic challenges for wildlife populations, including habitat fragmentation, novel predators, and pollution. These challenges may hinder animal communication and contribute to increased stress levels. This study will investigate the physiological consequences of stressors on the house sparrow (Passer domesticus). Specifically, we will examine how urbanization affects stress hormone (i.e., corticosterone, CORT) levels and its relationship to auditory processing. It is predicted that urbanization may impose novel stressors on animals, leading to differences in this hormone across urban and rural birds. We seek to understand if differences in CORT levels could impact animals' …

Experimental Validation Of Bio-Inspired Control: 4 Story Shear Structure, Vamsee Vemana

24th Annual A. Paul and Carol C. Schaap Celebration of Undergraduate Research and Creative Activity (2025)

With the rise of rapid urbanization, skyscrapers are increasingly common, making them vulnerable to environmental pressures such as high winds and earthquakes. These forces threaten the structural stability of tall buildings, necessitating the development of active control methods to mitigate their effects and maintain structural integrity. Traditional control systems utilize numerous sensing nodes that feed data into a centralized system, which then determines the appropriate actions for the actuators. However, this centralized approach can introduce substantial lag due to the overwhelming amount of data being processed. By transitioning to a decentralized wireless system, where sensors directly feed data to control …

Court Briefs

Introduction

When Fred Korematsu stood in the San Francisco federal district court in 1942 to challenge the constitutionality of a criminal charge that he had violated an exclusion order issued pursuant to Executive Order 9066, he was represented by pro bono counsel funded by the San Francisco office of the American Civil Liberties Union (ACLU). But just four days after Fred’s attorneys filed a motion to dismiss his criminal charges, ACLU director Roger Baldwin—wanting to avoid angering President Roosevelt—conveyed the “national board’s decision to prohibit test cases from challenging Roosevelt’s authority to issue Executive Order 9066.” Instead, local ACLU affiliates …

Ecosystems are experiencing changing global patterns of mean annual precipitation (MAP) and enrichment with multiple nutrients that potentially colimit plant biomass production. In grasslands, mean aboveground plant biomass is closely related to MAP, but how this relationship changes after enrichment with multiple nutrients remains unclear. We hypothesized the global biomass–MAP relationship becomes steeper with an increasing number of added nutrients, with increases in steepness corresponding to the form of interaction among added nutrients and with increased mediation by changes in plant community diversity. We measured aboveground plant biomass production and species diversity in 71 grasslands on six continents representing the …

The Impact Of Consuming An Electrolyte Drink Pre Vs Post-Workout On Recovery As Measured Through Urinary Indicators In Collegiate Cross-Country Runners, Laura Taylor, Aidan Becher, Madelynn Struck, Momodou Colley

24th Annual A. Paul and Carol C. Schaap Celebration of Undergraduate Research and Creative Activity (2025)

BACKGROUND: Hydration is crucial in sports, as dehydration can decrease strength, endurance, and power. Drinking electrolytes before and after intense exercise can promote hydration. Few studies have compared the difference in consuming electrolytes pre/post-workout. The impact of consuming electrolyte drinks can be assessed by comparing pre/post-workout urinary biomarkers (UB). PURPOSE: To determine if drinking electrolytes before/after a workout improves post-workout recovery as measured by heart rate (HR) and UB in collegiate Cross Country (CC) runners. METHODS: 21 CC runners (43% men, 20±3 years) were divided into four groups. For four weeks (Sep-Oct 2024), participants consumed Liquid IV (LIV) or a …

Foraging Efficiency Of Rural And Urban House Sparrows, Passer Domesticus, Among Natural And Unnatural Obstacles, Annie Waldron, Katie Kowalyk, Mara Gutierrez

24th Annual A. Paul and Carol C. Schaap Celebration of Undergraduate Research and Creative Activity (2025)

Urbanization may lead to food displacement for many animals. Urban birds are exposed to man-made objects that can result in variable food locations, unlike rural birds who inhabit areas where food locations are typically consistent. The introduction of unnatural obstacles may affect a sparrow's ability to find and reach food sources. Scientific studies have yet to find a significant increase in problem-solving skills related to foraging in urban versus rural birds. Our research seeks to determine the foraging efficiency of rural and urban house sparrows when exposed to obstructed food sources. Novel objects near a food source may scare birds …

The Impact Of Perfusion Techniques On Inflammatory Response During Cardiopulmonary Bypass; A Scoping Review, Rodolfo Alfaro

Student Works

Background: Cardiopulmonary bypass (CPB) is an essential part of cardiac surgery, but it leads to SIRS (systemic inflammatory response syndrome) which in turn increases postoperative complications. There are many proposed approaches to reduce inflammation, but there is no clear best practice on the approach to use. This scoping review aims to explore the literature and classify the studies that investigate the effects of various CPB perfusion techniques on inflammatory responses to determine the possible best practices and the gaps that exist in the literature.

Methods: The present scoping review was conducted according to the Preferred Reporting Items for Systematic Reviews …

Characterization Of Fibrotic Liver Tissue Microstructure For Predicting Shear Wave Speed Variability: A Machine-Learning-Based Computational Study, Emily J. Miller, Yongmei M. Jin, Jingfeng Jiang

Michigan Tech Publications

Objective: This study aimed to establish a link between the microstructure of simulated fibrotic liver tissues and the measured shear wave speed variability using a machine-learning-based approach. Approach: Fibrotic liver tissues were simulated using biphasic random fields. The underlying microstructure of the simulated fibrotic liver pathology (sFLP) was characterized using spatial pattern distribution analysis.A machine learning (ML) technique was implemented to identify top-rated spatial characteristic (SC) features and provide context for shear wave speed (SWS) variability, ultimately enabling us to use the SWS variability to infer its underlying tissue microstructure. Different combinations of top-three features were tested to understand the …

Traumas And The Development Of Personality Disorders, Madeline Raine Marler

Doctor of Psychology (PsyD)

Whereas studies have examined associations between traumatic experiences and the development of various disorders, a notable gap in the literature persists on the impacts of trauma timing and type (intergenerational vs. personal, chronic vs. singular) on the development of psychiatric diagnoses. This qualitative study utilizes a grounded theory approach, thematic analysis, and various coding techniques to explore linkages between trauma and the development of personality disorder(s). The population referenced for this dissertation was sourced from accessible archival data, consisting of transcript dynamic intake or follow-up interviews, Traumatic Antecedent Interviews (TAIs), and chart reviews from a long-established psychoanalytic clinic. The qualitative, …

Analysis Of Psychoactive Compounds In The Web-Building Behavior Of Mangora Maculata, Diane R. Castner

Undergraduate Honors Thesis Projects

The arachnid central nervous system (CNS) functions in an analogous way to the human CNS, despite spiders not having a central brain. Previous studies on spider behavior and web formation have investigated the impacts of stimulants, depressants, sedatives, and hallucinogens, but the impacts of serotonin reuptake inhibitors (SSRIs), such as fluoxetine are unknown. This study examined the impacts of caffeine, nicotine, ethanol, and fluoxetine on the web building behavior of Mangora maculata. Webs were characterized by 9 metrics: web entirety, size of web, radial angles, cell length, number of large holes, frequency of forking of spiral threads, radial angle consistency, …

Investigating The Effects Of Sex And Estrous Cycle On The Incubation Of Cue-Induced Oxycodone Craving, Bhumiben Pradipkumar Patel

Theses and Dissertations

The overprescription and misuse of opioids like oxycodone has played a significant role in the ongoing opioid crisis. While effective painkillers, drugs like oxycodone are also reinforcing and often misused. While sex and ovarian hormones can impact the analgesic effects of these drugs, the impact of these factors on oxycodone reinforcement are not fully understood. This relationship between ovarian hormones and opioid reward is further complicated by the fact that opioid use can disrupt ovarian hormone levels and produce reproductive cycle irregularities. Using a rat model of drug craving and relapse vulnerability, we found that chronic oxycodone exposure produced reproductive …

Investigating The Impact Trichoderma Virens On Maize Phytohormones During Drought, Salt, And Cold Stress, Kathryn Spencer

Theses

Abiotic stresses are becoming increasingly frequent and severe due to climate change, leading to significant reductions in crop yields. Though sessile, plants are not defenseless. They can invite plant-growth promoting microbes to colonize their rhizosphere and help reprogram their chemical defense systems. Through these partnerships, plants can more rapidly and robustly recover from environmental stressors compared to those grown in isolation. In this study, the role of the beneficial microbe Trichoderma virens in phytohormone production was explored in maize, a globally important staple crop, under drought, salt, and cold stress, with or without microbial inoculation. Using a liquid chromatography mass …
