Evolutionary Stasis In Life History Traits Between Xenophallus Clades Isolated During Pliocene Marine Incursions, Elias Johnson, Jerald B. Johnson

Library/Life Sciences Undergraduate Poster Competition 2025

Why do some species fail to evolve? The chiral livebearer, Xenophallus umbratilis, is found in Central America. Populations within this species have been isolated from each other for millions of years due to marine incursions, big rivers, and ecological filters downstream, leading to divergent clades (figure below). However, these isolated populations persist under similar ecological conditions, including the absence of predators and in similar headwater habitat types.

The search process yielded evidence of both overrepresentation and underrepresentation of English learners in special education, with some studies indicating disproportionality in specific disability categories. Underrepresentation was found to be present in categories of emotional behavioral disability, speech and language impairment, other health impairment, attention-deficit hyperactivity disorder, and autism. Overrepresentation was found to be present in multiple disability categories, especially with specific learning disabilities and speech language impairment. Potential variables that could be contributors to overrepresentation were found to be educators’ …

Understanding The Individual Behavioral Variation Of Asian Elephants (Elephas Maximus) As An Indicator Of Human Elephant Conflict, Julia Brzezicki

Masters Theses & Specialist Projects

Human-Elephant Conflict (HEC) is an increasingly common event that arises from resource competition due to overlaps in human and elephant environments. Using a conservation behavior approach, the behaviors of elephants can be studied to enhance conservation efforts to mitigate HEC by better predicting which elephants engage in HEC. To understand the factors that affect individual behavioral types of adult Asian elephants (Elephas maximus), my project examined the behavioral patterns displayed by an elephant population in Sri Lanka. I collected demographic and behavioral data of a subset of 15 adult elephants to determine individual differences in five behavioral categories: Affiliation, aggression, …

A Systematic Study Of The Highly Endemic Spider Beetle Fauna (Coleoptera: Ptinidae: Ptininae) Found In The Coastal Deserts Of Perú, Marlena Askren

Masters Theses & Specialist Projects

Spider beetles are small, often flightless insects that occur in hyperarid environments around the world. They exhibit interesting morphology and behavior that allows them to conserve water they obtain from plant material, dung, and other detritus. One hyperarid region in which they are found is the Pacific coast of Perú and northern Chile. The Sechura Desert, Peruvian Coastal Desert, and Atacama Desert make up the arid coast where spider beetles occur from north to south.

Incorporating Mindfulness Techniques In Therapeutic Practices To Impact A Patient’S Pain Perception, Abigail E. Masters

2025 Honors Symposium

Background: Chronic pain is a widespread condition that affects millions of individuals and leads to substantial healthcare costs, with estimates in the U.S. ranging from $560 billion to $635 billion annually. Traditional pain management heavily relies on opioid prescriptions, which, while effective in the short term, have contributed to the ongoing opioid crisis due to risks of addiction and dependency. As a result, there is a growing interest in alternative, non- pharmacological approaches to pain management, including mindfulness-based interventions (MBIs). MBIs have been increasingly recognized for their ability to help patients modulate pain perception and improve overall well-being. This study …

Dissertations of Practice

This convergent mixed-methods study explored how secondary school English as a Foreign Language (EFL) teachers in Uruguay changed their pedagogical content knowledge (PCK) of social emotional learning (SEL), and their beliefs about their role in SEL integration, after participating in a six-week online professional development (PD) course. Amid increased international emphasis on the importance of social and emotional competencies (SECs) for students’ academic and personal success, Uruguay’s EFL national curriculum calls for the promotion of these competencies, yet offers limited guidelines or training for their EFL educators. The PD course was designed by the researcher to address this gap, providing …

Crosslinking Effects On High-Oleic Soybean Oil-Based Anionic Polyurethane Dispersions, Zoran Petrović, Jasna Djonlagić, Jian Hong, Milica Lovrić Vuković

National Institute for Materials Advancement

Waterborne polyurethane dispersions are known as non-toxic, non-flammable, environmentally friendly products widely used in the coatings industry. We prepared a series of anionic dispersions based on the polyol from high-oleic soybean oil, isophorone diisocyanate and dimethylol propionic acid. Stable anionic dispersions were achieved when the acid content in formulations ranged from 7.7 to 10.8 wt%. All dispersions in this series had average particle sizes of 163–211 nm with unimodal size distribution. Utilization of the high-oleic oil, with three double bonds on average, and the resulting trifunctional polyol, renders crosslinked products with improved hydrophobicity and excellent chemical and physical properties. Also, …

Impulsivity And Investment Risks: A Behavioral-Economic Analysis Of Magnitude Effects In Decision-Making, Samuel C. Latty

Psychology

Human decision making involves weighing probabilistic outcomes and uncertainty alongside the magnitude of potential gains and losses. Delay discounting refers to a perceived decline in the present value of a reward as the delay to acquisition increases. Impulsivity can be reflected by an individual's preference for smaller, immediate reward compared to larger, delayed reward. Experimental manipulation of tasks such as the Iowa Gambling Task (IGT) have been introduced to evaluate individual sensitivity to risk in monetary decision-making scenarios. In the current study, we compared two versions of the IGT, one with original magnitudes and one with high magnitudes. We proposed …

The Winning Combination: A Study Of The Experiences Of Black Women Head Women Basketball Coaches On The Division I Level, Monique Bernoudy

Dissertations of Practice

Black women serving as NCAA college head women’s basketball coaches have limited representation and opportunities especially at the most elite Division I Football Bowl Subdivision (FBS) level. In Division I FBS women’s basketball programs, White women hold 38% of the head coaching positions and Black women hold 22. This is troubling because women’s basketball rosters reflect a quantity of Black women assistant coaches (37%) and Black women student-athletes (46%) which exceed the quantities of their White peers, yet they fail to rise in equitable quantities into head coaching positions. There is no plausible explanation for the inequitable representation of Black …

Biocultural Mobility: The Impact Of Osteoarthritis On Rural Kentuckians, Alexandria Anderson

Mahurin Honors College Capstone Experience/Thesis Projects

OA has a complex etiology, with various biological, mechanical, and sociocultural factors affecting its acquisition and progression. Like most diseases, OA has a differential prevalence among populations; it is disproportionally more common in underserved communities, including rural areas. This thesis presents (1) a study comparing selected OA treatment type and patient travel time, (2) a study comparing OA comorbidity amount and rurality, and (3) a discussion of exploratory interdisciplinary methods in …

The Effects Of The Replication Crisis Instruction On Skepticism, Ericka Hoppes

Mahurin Honors College Capstone Experience/Thesis Projects

Over the past decade, there has been growing concern regarding the Replication Crisis in psychology. The crisis has called into question the credibility of psychological research by highlighting the field’s difficulty in reproducing findings (Open Science Collaboration, 2015), as well as the prevalence of questionable research practices amongst psychologists (e.g., p-hacking, falsifying data, incomplete reporting of measures, etc.). Given that the crisis presents psychological research through a critical lens, learning about the aspects of the crisis can be a useful pedagogical tool for helping students develop a healthy sense of skepticism regarding scientific studies. The present study investigated how teaching …

The Birth Experience During The First Wave Of Covid-19 Lockdown In New York Hospitals: A Qualitative Study, Emily Morse Small M.S.

Selected Full Text Dissertations, 2011-

In 2020, alongside the onset of the SARS-CoV-2 (COVID-19) pandemic, 209,338 births occurred in New York State (Osterman et al., 2022). While much of the public adjusted to working or learning in a virtual world, many hospitals in New York remained open to treat those in need of care. Women nearing the end of their pregnancy, many of whom felt that they had no other choice, found themselves headed to the hospital—to the labor and delivery unit. Many studies completed outside of the United States on the birth experience during the pandemic found an increase in the likelihood of negative …

Contraceptive Counseling For Transgender & Gender Diverse Patients: Provider Knowledge & Experience, Kathryn Callahan

Yale Medicine Thesis Digital Library

Many transgender and gender diverse (TGD) individuals have contraceptive needs. Contraceptive counseling in this population is often nuanced due to the diverse experiences and healthcare goals of TGD individuals. Testosterone therapy is an important component of gender affirming care for some transgender and gender diverse (TGD) individuals. A common misconception among patients and providers is the role of testosterone in pregnancy prevention. Testosterone is not an effective form of contraception due to its inconsistent suppression of ovulation. Previous studies have shown that some patients who use testosterone for contraception do so based on guidance from their healthcare provider. Therefore, this …
