Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Urban heat island (UHI) effects are amplified by disparities in community-level cooling infrastructure—such as urban public parks and open spaces (PPOS)—with the most severe impacts occurring in communities that lack sufficient city-wide cooling resources. We found that the underserved community of South Los Angeles, as compared to their neighboring West Los Angeles counterparts, suffers a double burden of inequitable (1) access to and (2) absence of cooling materials and surfaces within these spaces, resulting in significantly hotter temperatures. Identifying these inequities requires high-resolution temporal and spatial mapping of surface temperatures, which has been previously limited. In this community-based participatory research …

In the face of danger, crowds of civilians decided to leave their homes and escape, among others, to Poland in search of shelter. Materials and methods: The research was conducted on groups of refugees from Ukraine who registered in the first days of the war in Sopot and Pruszcz Gdanski. The refugees came from Kharkov, Mariupol, Kherson, Zaporizhzhia, and western Ukraine (not involved in hostilities). People from the war zone areas mostly came with only hand luggage. The respondents were divided …


Living In Liberal Areas Reduced Covid-19 Vaccine Hesitancy Among Conservatives, Brittany L. Kmush, Rachel E. Dinero Mar 2026

Living In Liberal Areas Reduced Covid-19 Vaccine Hesitancy Among Conservatives, Brittany L. Kmush, Rachel E. Dinero

Population Health Research Brief Series

Political divisions shaped public health responses throughout the COVID-19 pandemic, with conservatives expressing higher vaccine hesitancy than liberals. But does where conservatives live matter? This brief summarizes findings from a study using survey data from 683 U.S. adults (ages 18-94) collected March-April 2023, combined with 2020 presidential election results by zip code. The authors found that liberals consistently had low vaccine hesitancy and high uptake regardless of where they lived, but conservatives living in lower Trump vote share communities reported lower vaccine hesitancy and higher vaccination and booster uptake than conservatives in high Trump vote share communities. This pattern was …

Patient Presentation Affects Medical Student Comfort During Sexual Health Encounters, Harshith Jella, Emily J. Noonan, Laura Weingartner Mar 2026

Patient Presentation Affects Medical Student Comfort During Sexual Health Encounters, Harshith Jella, Emily J. Noonan, Laura Weingartner

The Cardinal Edge

BACKGROUND

Previous research has identified some disparities between the care that masculine- and feminine-presenting patients experience with regards to sexual health. These disparities could cause feelings of unease and also difficulty with patient-physician communication. In medical education, standardized patients can help students identify and address implicit biases that could propagate as providers.

METHODS

The study population consisted of second year medical students (n=100) from the University of Louisville who completed sexual history-taking during a standardized patient encounter. Coders evaluated the phrases used, perceived comfort levels, and SP feedback among masculine- and feminine-presenting standardized patients.

RESULTS

While the patient presentation did …

Hallucinogens For Mood And Anxiety Disorders: A Critical Review Of Psychedelic-Assisted Therapies, Georgia Chlebek

The Cardinal Edge

In quite a few people worldwide, there are several mental disorders that prevent the brain from operating in the “proper” way, depression, anxiety, and post-traumatic stress disorder (PTSD) being among the most common. Luckily, there are several medications that are produced and used to treat these disorders, but some medications are hard to access, and others simply don’t help the patient. Firstly, these medications take time to study and prove safe for public use, though in some cases time is not readily available. In other cases, these medications are going through shortages and becoming increasingly difficult for patients to access …


Intergenerational Hypertension Transmission Before And After South Africa's Democratic Transition, Winfred A. Avogo Mar 2026

Intergenerational Hypertension Transmission Before And After South Africa's Democratic Transition, Winfred A. Avogo

Faculty Publications – Sociology and Anthropology

Background: Apartheid's structural violence produced profound cardiovascular inequalities among Black South Africans through processes that accelerate biological aging ("weathering") and transmit health disadvantage across successive generations. Whether South Africa's 1994 political transition interrupted this intergenerational transmission remains unknown. This study tests whether parent-to-offspring hypertension transmission weakened among cohorts born after apartheid's end, using the 1994 transition as a natural experiment. Methods: This study analyzed 30,438 parent-offspring dyads from five waves (2008–2017) of South Africa's National Income Dynamics Study, representing 11,655 unique offspring aged 18 years and older. Hypertension was defined as blood pressure ≥140/90mmHg or use of antihypertensive medication. Logistic …

Conjoined Twins And Abortion Restrictions: Navigating 'Ban State' Challenges, A Case Report, Beau Morgan Nrp

Pursuit - The Journal of Undergraduate Research at The University of Tennessee

This case report highlights an unusual scenario of a conjoined twin pregnancy resulting from intrauterine insemination in a state with restrictive abortion laws. Despite a diagnosis deemed not compatible with life, the patient faced legal barriers preventing termination within their home state. Forced to seek care out-of-state, the patient underwent a successful termination at ten weeks and three days after lengthy and expensive travel. This case stresses the complex challenges posed by restrictive abortion laws, impacting patient access to essential medical interventions. The case demonstrates the critical intersections between medical care, medical ethics, legal constraints, and patient outcomes in managing …


The Schizophrenia Effect: Families Facing Schizophrenia-Spectrum Disorders, Ginger A. Christmas Mar 2026

The Schizophrenia Effect: Families Facing Schizophrenia-Spectrum Disorders, Ginger A. Christmas

Doctoral Dissertations and Projects

Schizophrenia is primarily known for its bizarre psychosis, as the brain struggles to distinguish between what is real and what is not. This qualitative study employed constructive, interpretative phenomenological analysis (IPA) to explore the idea that families with a family member diagnosed with a schizophrenia-spectrum disorder (SSD) in the United States have specific needs, which may include social and spiritual support and integration into treatment. While the needs of families facing SSD have been studied in non-Western countries, the schizophrenia effect on families in the U.S. remains less understood. A purposive sample of 11 individuals, representing 15 family members with …


Redesigning Online Graduate Orientation To Foster Academic Resilience And Prevent Underperformance, Stella Michael-Makri, David E. Rodriguez Mar 2026

Redesigning Online Graduate Orientation To Foster Academic Resilience And Prevent Underperformance, Stella Michael-Makri, David E. Rodriguez

Journal of Academic Underperformance

Graduate students in fully online programs often begin their academic journey without adequate preparation for the emotional, structural, and cultural challenges of graduate-level work. For students who are first-generation, racially marginalized, international, or returning to education after time away, this lack of scaffolding can lead to early disengagement, underperformance, or attrition. Orientation, often treated as a checklist of logistical tasks, represents a missed opportunity for meaningful academic intervention. This manuscript proposes a five-module conceptual model for online graduate orientation designed to proactively support online graduate students in the domains of emotional regulation and academic identity, time management and executive functioning, …

Glynn, Elysia Poggi Davis, Tallie Z. Baram, Caroline M. Nievergelt, Giovanni Castillo, Christian Cortes, Christine Y. Chang, Dewleen Baker, Victoria B. Risbrough

Psychology Faculty Articles and Research

Background

Unpredictability in the child’s environment has recently emerged as a significant and unique form of early life adversity (ELA). Cross-sectional studies have linked childhood unpredictability with increased post-traumatic stress disorder (PTSD) symptoms in adults; however, no prospective studies have tested the link between childhood unpredictability and PTSD risk in later life, nor what processes, such as increased anhedonia symptoms, might mediate such risk. Here, we leveraged three distinct prospective, longitudinal cohorts to test the hypothesis that unpredictability during childhood contributes to adult PTSD via worsening anhedonia symptoms.

Methods

Participants were male service members (n=314), adult females (n=170), and adolescents …

The Effectiveness Of Mode Deactivation Model Group Counseling In Improving The Emotional Wellness Of Junior High School Students, Ananda Dwi Rahmadanti, Muya Barida, Sri Hartini, Aprilia Setyowati

Buletin Konseling Inovatif

This study was motivated by the low level of emotional wellness among some junior high school students, characterized by difficulties in recognizing, understanding, and managing emotions adaptively, thereby impacting social behavior and learning processes at school. Previous studies have shown that emotion regulation-based interventions are effective in improving adolescents' emotional well-being. However, counseling interventions in schools that specifically target emotional regulation patterns to improve students' emotional wellness are still relatively limited in guidance and counseling services. Therefore, this study aims to examine the effectiveness of group counseling using the Mode Deactivation Counseling (MDC) model in improving the emotional wellness of …

The Phoenix Trauma Response Model (Ptrm): An Integrative And Innovative Approach To Trauma Recovery And Growth, Latesha S. Holloman, Lauren B. Robins, Tammie Willis, Courtney V. Morris Mar 2026

The Phoenix Trauma Response Model (Ptrm): An Integrative And Innovative Approach To Trauma Recovery And Growth, Latesha S. Holloman, Lauren B. Robins, Tammie Willis, Courtney V. Morris

Journal of Human Services Scholarship and Interprofessional Collaboration

Trauma is increasingly understood as a developmentally consequential experience that shapes identity, regulation, and relational functioning across the lifespan. Although trauma-informed care, resilience theory, posttraumatic growth, and narrative approaches have expanded understanding of recovery, few frameworks articulate a structured developmental progression that integrates prevention, intervention, and intergenerational transformation within a unified model. The Phoenix Trauma Response Model (PTRM) addresses this gap by introducing a cyclical, phase-based framework organized around four interrelated processes: Recognition, Reframing, Reclamation, and Replication of Strength. Central to the model is the construct of conversion potential, defined as the structured capacity to translate distress into purposeful …


An Odd Protocol For An Agent-Based Model Of Hepatitis C Virus Transmission In A Homogeneous Syringe-Sharing Network, Seun Ale, Que Thi Nguyet Nguyen Dr., John D. Kelleher Prof., Elizabeth Hunter Dr. Mar 2026

An Odd Protocol For An Agent-Based Model Of Hepatitis C Virus Transmission In A Homogeneous Syringe-Sharing Network, Seun Ale, Que Thi Nguyet Nguyen Dr., John D. Kelleher Prof., Elizabeth Hunter Dr.

Reports

The model described in this ODD is an agent-based model of hepatitis C virus (HCV) transmission among people who inject drugs (PWID). The model assumes homogeneous mixing among syringe-sharing agents, without any form of heterogeneity in the agents interactions or syringe-sharing attitude. All syringe-sharing PWID are treated as identical in terms of their interaction frequency and syringe-sharing probability. Interactions are generated dynamically using proximity-based sampling at each timestep (one day), allowing agents to form syringe-sharing interactions based on spatial closeness. The number of daily interaction events is fixed at the population level, and each syringe-sharing agent has the same probability …
