Invasion Of Microplastics Into The Reproductive Tissues Of Feral And Domestic Felines, Emma K. Quade

Honors Undergraduate Theses

Although plastics have many useful properties in modern society, once these materials are introduced into the environment, they can cause extensive damage. Following degradation into microplastics (MP), plastic particles less than 5 mm in size, these contaminants can make their way into a variety of different environments and organisms. There are many studies that have investigated the prevalence of MP in marine environments, but fewer studies have looked into terrestrial systems, and even less that have focused on contamination in companion animals. This study sought to investigate the invasion of MP into the reproductive tissues of felines, Felis catus, …

Brief Therapy Dog Interactions May Increase Self-Efficacy And Lower Perceived Stress And Cortisol In High School Students: A Preliminary Study, Dawn Melzer, Deirdre Yeater, Madison Derubis, Christiana Rose Kohlroser, Barbara J. Pierce

Psychology Faculty Publications

The present study examined changes in high schoolers’ perceived stress, general self-efficacy and cortisol levels after a brief interaction with a certified therapy dog. High school students completed self-report measures of perceived stress and general self-efficacy and provided salivary cortisol samples both before and after a 10-min interaction with a certified therapy dog. Following the interaction, students reported reductions in perceived stress scores, exhibited lower salivary cortisol concentrations and demonstrated increases in self-efficacy scores compared to before the interaction. Although higher self-efficacy scores were observed, general self-efficacy is generally regarded as a stable construct; therefore, these findings may reflect a …

The Disruption Of Gastrointestinal Hormonal Control Of Digestion In Nile Tilapia By Omeprazole, Rema Abutaha

Theses and Dissertations (Comprehensive)

Stomach acidity is a critical feature of the digestive system, facilitating the breakdown of protein through the activation of the protease pepsin. Gastric acid is secreted by H⁺/K⁺ ATPase, the gastric proton pump. A previous study on Nile tilapia (Oreochromis niloticus) showed that inhibiting the production of stomach acid using the proton pump inhibitor omeprazole (omz), reduced growth that correlated with an acceleration of the rate of gastric emptying. This contrasts with omz exposure studies in mammals in which there is a delay in gastric emptying and no impact on growth. To understand the mechanism …

The Effect Of The Affordable Care Act Medicaid Expansion On The Risk Of Hospital Closure And Adolescent Hpv Immunization In Rural Counties, Juliette Des Rosiers

Scripps Senior Theses

From 2005 to 2025, over 200 rural hospitals shut their doors, often citing increased operational costs, staffing shortages, low patient volume, regulatory barriers, financial challenges exacerbated by the COVID-19 pandemic, and uncompensated care as common contributors to the closures. Rural patients are often referred by their primary care physician to a hospital for regular immunizations, since smaller clinics have less capacity to provide immunizations due to a shortage of pediatricians and limited vaccine stock. A crucial vaccine that is not required by schools and underutilized in rural areas is that against human papillomavirus (HPV), a virus that infects cutaneous and …

Advances in statistical techniques for analyzing biological data have driven the need for larger sample sizes, which are ultimately made possible through team science efforts. Findings from these efforts have led to a significant shift in approaches to biological data collection over the past decade, from traditional approaches relying on single measures or assays collected by individual investigators in small lab-based studies to high-dimensional methodologies embedded within large cohorts or multi-site studies. These recent large scale consortium efforts necessitate careful consideration across the full data pipeline, from pre-data generation and sample collection to processing and statistical analysis, while addressing challenges …

Differentiation Of Cell Populations In Saliva-Skin Mixtures Using Autofluorescence Profiling, Kara Fairfax

Master of Science in Forensic Science Directed Research Projects

While DNA profiling of sexual assault evidence can identify biological contributors, determining the tissue source of recovered profiles remains a significant challenge, particularly in cases of suspected oral assault involving mixtures of epithelial cells. The initial goal of this study was to identify non-genetic signatures for differentiating two types of epithelial cells relevant to oral assaults, saliva epithelial cells and epidermal skin cells. To develop tissue-specific signatures, reference cell populations from saliva and epidermal skin surfaces were collected from 20 donors and analyzed using full spectrum flow cytometry.

Results from single-source reference samples showed that saliva-derived particle populations exhibited higher …

Some New Ecological Aspects Of The Lesser Sunda Endemic Drepanosticta Berlandi (Odonata: Zygoptera: Platystictidae), Muhammad Zulhariadi, Muhammad Setyo Nugroho, Nurul Hidayani

Makara Journal of Science

Drepanosticta berlandi is an endemic damselfly in the Lesser Sunda region of Indonesia, which was first recorded on Lombok Island in the 19th century. Albeit recognized for a century, information on its ecology is still lacking; hence, this study aims to reveal its distribution and habitat preferences. The research was conducted at the Tibu Ijo Waterfall tourist area in West Lombok Regency using line transects combined with field survey in the Kekait River and on footpaths on both sides of the river. Vegetation density, topography, and land survey temperature (LST) were measured at the sampling area using ArcGIS 10.4.1 software. …

Developing A Tool To Measure Resistance To Sustainable Food Choices: A Pilot Study In Ireland And The Netherlands, Kate Flanagan, Bart Sinteur, Patricia J. Bulsing, John M. Kearney

SURE Journal: Science Undergraduate Research Experience Journal

Consumer uptake of a sustainable diet is critical for addressing environmental challenges and promoting public health. Understanding why consumers resist adopting sustainable eating habits can inform targeted interventions and policies. This pilot study examines whether a newly developed scale can effectively detect consumer resistance to a sustainable diet. Currently, there is a lack of research on a tool to measure consumer resistance to a sustainable diet, highlighting the need for a reliable instrument.

The aim of this study is to develop a scale, based on existing literature, to measure consumer resistance to a sustainable diet. Additionally, the study aims to …

The Chemistry Of Color: A Comparative Analysis Of Natural And Synthetic Dyes In Textile Application, Caitlyn Pinaga Cpht

Honors Program Theses and Research Projects

The Chemistry of Color: A Comparative Analysis of Natural and Synthetic Dyes in Textile Application examines how color functions at the intersection of chemistry, culture, and environmental responsibility. This project traces the evolution of dyeing from ancient natural pigment traditions, rooted in ecological knowledge, agricultural practices, and cultural identity, to the industrial rise of synthetic dyes, whose laboratory precision enabled unprecedented consistency, brightness, and global textile expansion. Through experimental swatch analysis, the study compares the behavior of natural dyes derived from plants and food sources with modern fiber-reactive and synthetic dye classes on a range of fibers including cotton, bamboo …

From Collision To Coexistence: Data-Driven Approaches To Reducing Wildlife Rehabilitation Center Intakes, Alice Anastos

Honors Projects

This project investigates the primary anthropogenic drivers of wildlife admissions at Lake Erie Nature and Science Center using a quantitative analysis of 10,172 intake records from the WILD-ONe database. Window collisions were by far the leading cause of admission, accounting for 54% of all intakes. Orphaning represented 12%, followed by vehicle collisions (5%) and domestic cat attacks (4%). By integrating findings from current wildlife rehabilitation research, this study identifies evidence-based strategies, such as bird-safe window treatments, public education on natural animal behavior, and targeted urban planning, that can substantially reduce preventable injuries. These results underscore the need for context-specific outreach …

Exploring The Relationship Between Loneliness And Real-Time Measurements Of Gsr And Hrv During Concept Mapping, And Cortisol And Oxytocin Levels, Jangwon Seo

Masters Theses

This study attempts to explore loneliness among college students from a bio-physio-psycho-social perspective, and it utilizes real-time physiological measurements (GSR and HRV) and biomarkers (cortisol and oxytocin) in conjunction with psychosocial assessments. The study employs both qualitative and quantitative methods, which involve concept mapping exercises, with the aim of comprehending the full nature of how loneliness interacts with physiological and psychological processes. At Time 1 (T1) we found significant positive correlations between loneliness and elevated GSR levels, which is indicative of increased sympathetic arousal (r = .35, p < .01). Additionally, there were significant negative correlations between loneliness and mean RR intervals in HRV that indicated autonomic dysregulation featured by increased sympathetic activities as well as reduced parasympathetic functions (r = -.28, p < .05). However, at Time 2 (T2), these correlations were not significant indicating possible temporal fluctuations due to adaptive responses or extraneous variables such social support systems or coping mechanisms. The qualitative data from concept mapping enriched the analysis by providing deeper insights into the cognitive and emotional processes underlying loneliness. Despite limitations like demographic skewness, funding constraints, logistical challenges, etc., this, therefore, highlights the need for multidimensional investigations of psychological phenomena. This has implications for future research as well as clinical practice, which could include using these integrative measures to develop holistic interventions for mental health disorders.

Applicability Of Cementochronology To Estimate Season-Of-Death In Humans: Insights From Modern Documented Collections, Olga Ibarra-Sanchez

Theses and Dissertations

Dental cementum is characterized by lifelong deposition of alternating opaque annuli in fall/winter and translucent bands in spring/summer. This study aims to test the applicability of cementochronology to estimate season-of-death, by observing the properties of the last layer, with direct implications for forensic anthropology and bioarchaeology. The sample includes canine teeth from 146 adults (84 males, 62 females), age-at-death ranging from 20-97 years (mean=61.7 years, SD=18.6 years), from two contemporary skeletal collections. Of these individuals, 78 (53.4%) died in spring/summer and 68 (46.6%) died in fall/winter. Overall accuracy was low at 64.4% (94/146). Accuracy was higher for spring/summer deaths 100.0% …

Artificial Light At Night Can Worsen Competitive Outcomes Between Native And Invasive Grasses, Shannon M. Murphy, Kylee Grenis, Anna A. Sher

Biological Sciences: Faculty Scholarship

Artificial light at night (ALAN) is an important global disturbance that affects community dynamics, but how it affects species interactions, such as competition, is not well understood and needs investigation. In plant communities, some exotic-invasive plant species seem to be facilitated by ALAN, which may alter competitive outcomes with native plant communities and promote invasion. Despite these intriguing results, whether ALAN affects competitive outcomes between native and invasive species is understudied. Here we tested how ALAN affects competitive outcomes between two native prairie grasses and two grasses that are exotic-invasive in North America. We planted each native species with a …
