Psilocybin And Death Anxiety: A Dual-Mechanism Approach To Existential Distress, Annabelle Swain

University Honors Theses

This literature review looks at how psilocybin, the active compound in "magic mushrooms," can help people deal with death anxiety; the deep fear of dying or losing control that shows up in lots of mental health struggles. While traditional treatments like SSRIs and talk therapy work for some people, they don't always get to the root of the problem. Psilocybin works differently. It changes brain activity, especially in networks tied to repetitive, self-focused thinking, as well as creates powerful, emotional experiences that help people rethink how they see life and death. This paper covers recent research showing how one or …

Link Between Adverse Childhood Experiences And Parenting Styles Of African American Fathers, Tatianna P. Johnson

Dissertations

African American fathers may be more susceptible than fathers of other races to having a negative parenting style due to their high levels of adverse childhood experiences (ACEs). ACEs are traumatic experiences during childhood that can affect a person’s mental and physical health, income and adult parenting style. African American adults tend to have experienced multiple levels of ACEs at a higher rate than White and Asian adults (Maguire-Jack et al., 2021). ACEs can lead to adults experiencing higher levels of alcoholism, depression, health-related issues, mental illness, substance use, and academic problems. The purpose of this cross-sectional study was to …

Participants reported adapting workflows to meet religious, language, and communication needs through human and technological tools. The study underscores embedding cultural …

Perceived Obligations Of Older Partners In Living-Apart Together Relationships, Allison M. Martin

Human Development and Family Sciences Undergraduate Honors Theses

Older and middle-aged adults are increasingly in Living-Apart-Together (LAT) relationships characterized by committed romantic relationships without marriage and cohabitation. Because of assumptions that older adults will receive family caregiving as they grow older and need caregiving, it is not clear how people are likely to perceive obligations to provide caregiving assistance. As adults move into old age and incidence rates of Alzheimer’s Disease or Related Dementia (ADRD) increase, questions about the availability of family members to provide needed assistance are complicated by LAT relationships. The purpose of this study was to examine perceived obligations to provide assistance to older adults …

Pediatric Occupational Therapists’ Perception On How Nature-Based Play Affects Fine Motor Development, Abbi M. Rosenow

Human Development and Family Sciences Undergraduate Honors Theses

This study aimed to explore the benefits of nature-based pediatric occupational therapy and the influence of nature and nature-based play on fine motor development. It was hypothesized that nature and nature-based play would positively impact a child’s fine motor skills, and that nature-based occupational therapy would offer unique benefits to a child’s therapeutic experience. To examine these relationships, a survey was distributed to pediatric occupational therapists across the United States. The survey was designed to gather insights into how occupational therapy supports fine motor development, how nature-based play/therapy enhances these skills, and the perceived benefits of incorporating nature into therapeutic …

Role Of Cellular Proteins In The Regulation Of Herpes Simplex Virus Type 1 Gene Expression And Dna Replication, Joseph R. Heath

Electronic Theses and Dissertations

Herpes simplex virus type 1 (HSV-1) is a ubiquitous human pathogen that infects the majority of the human population. To facilitate infection, this virus relies on a combination of host and viral factors. Previous studies have revealed a number of host proteins that associate with the HSV-1 genome throughout infection but their putative role(s) in this process remain undefined. This study aims to examine two such proteins to determine their contributions to HSV-1 gene expression and DNA replication. The first of these factors is Ints3, a subunit of the Integrator complex. This protein complex functions in transcription regulation, and Ints3 …

Cg18562578 Methylquant Assay For The Discrimination Of Monozygotic Twins, Amber P. Chauca

Student Theses

Monozygotic (MZ) twins have identical DNA, making traditional profiling methods insufficient in their discrimination. However, MZ twins can be differentiated by their levels of DNA methylation. Our research group previously developed a methodology to detect cg18562578 DNA methylation levels in MZ twins based on a two- step PCR approach and a cg18562578 MethylQuant Assay. That study generated data for only 64% of the samples it investigated, and showed a discrimination power of 77% to discriminate between MZ twins. Here, we used the same methodology but a different approach to determine DNA methylation in 73 previously unsuccessful twin pairs. We diluted …

Invisible Algorithms, Visible Outcomes: Roles Of Emotional Labor And Work Gamification In Gigs, Yali Zhang, Liaoliao Li, Xiaoyu Ma, Jun Sun, Yifei Dong, Zhaojun Yang

Information Systems Faculty Publications

As algorithm governance becomes increasingly crucial in gig economy ecosystems, understanding the behavioral impact of algorithmic transparency remains a key research gap. Using the stimulus-organism-response framework and uncertainty management theory, this study examines how platform algorithmic transparency affects gig workers’ in-role and extra-role service behaviors, with emotional labor acting as a mediator and work gamification as a moderator. Analyzing survey data from 325 ride-hailing drivers using partial least squares structural equation modeling (PLS-SEM), the findings reveal that greater algorithmic transparency enhances both in-role and extra-role behaviors. Emotional labor mediates this relationship: deep acting strengthens both behaviors, while surface acting primarily …

Influence Of A Summer Bridge Program On African American Students At East Tennessee State University, Carshonda Harris

Masters Theses and Doctoral Dissertations

The purpose of this research was to investigate if there was a significant difference of academic success between African American participants and non-participants of the B.U.C.S. Academy program, a summer bridge program, at East Tennessee State University (ETSU). Although African American students’ enrollment has increased for several years, this population remains underrepresented in comparison to majority groups regarding retention, grade point average, and attainment of bachelor’s degrees (East Tennessee State University, 2021).

Exploring The Mediating Role Of Individual Performance In The Relationship Between Work-Life Balance And Attrition, Grace O. Leasure

Research Psychology Theses

Extensive research has established a relationship between work-life balance and employee attrition. However, limited attention has been given to the potential mediating role of individual performance within this dynamic. The present study aims to address this gap by examining whether individual performance mediates the relationship between work-life balance and attrition. It is hypothesized that higher work-life balance will be associated with lower attrition rates, partially explained by improved individual performance. Data will be collected via employee surveys and analyzed using mediation analysis. Anticipated results may provide organizations with a quantifiable, performance-based justification for investing in work-life balance initiatives.

When Opportunity Knocks, Do Dark Personality Traits Aid In Students’ Rationalization Of Academic Misconduct?, Jacqueline R. Strowd

Dissertations

Concerns about academic misconduct are receiving increased attention within academia due to a proliferation of advanced technologies and reports of the high prevalence with which students engage in misconduct. Contextual factors (e.g., peer acceptance, opportunity) appear to be stronger predictors of students’ propensity for academic misconduct than individual factors (McCabe & Trevino, 1997). The Fraud Triangle Theory (i.e., pressure, opportunity, rationalization) has been adapted to this context and provides a useful theoretical model for considering contextual factors (Cressey, 1973; Wolfe & Hermanson, 2004). Research integrating this theory with the Dark Triad (i.e., Machiavellianism, narcissism, psychopathy) suggests that these traits may …

A Brief Cognitive-Behavioral Intervention For Emotion Regulationand Aggression In Justice-Involved Adolescents: Preliminary Outcomes From A Non-Randomized Trial In Short-Term Juvenile Detention, Cassidy L. Tennity

Dissertations

Justice-involved youth are at risk for a variety of psychosocial difficulties, including anger, aggression, and emotion regulation challenges. Short-term juvenile detention settings offer a unique opportunity to provide psychological interventions to youth before they are returned to the community or sentenced to long-term placements. However, implementation barriers within these settings often hinder the delivery of evidence-based care. This study developed and tested a brief, two-session anger management intervention for adolescents detained in a short-term juvenile detention center in the Southeastern United States, drawing on evidence-based practices from prior work with justice-involved youth. The present study examined implementation outcomes (i.e., feasibility, …

Test Driving Proximity Distances For Teacher Implementation Of Effective Instruction Delivery, Kenneth Joseph Ross Ii

Dissertations

Student noncompliance can disrupt teacher instruction and affect students’ ability to learn in the classroom. Interventions can be provided to teachers within the PBIS tiered system to address noncompliance. One intervention that addresses noncompliance, Effective Instruction Delivery (EID), has been demonstrated to increase levels of compliance above baseline levels. Despite the effectiveness of evidence-based interventions such as EID, there are significant concerns with ensuring the feasibility of evidence-based interventions to match the needs of teachers in the classroom to reduce teacher burn-out. A possible strategy to promote high levels of fidelity is to allow teachers to test drive interventions before …

The Impact Of Gender, Training Year, Medical Specialty And The Covid-19 Pandemic On Resident Wellness, Sara Beachy, Jessica Luzier, Chantel Weisenmuller, Kathleen Bors, Mary Ann Maurer, Amna Anees, Tiffany Lasky, Lisa Calderwood

Department of Family & Community Medicine Faculty Papers

INTRODUCTION: Data are limited as to which factors most strongly impact medical trainees' well-being, and few studies have assessed trainee's wellness at multiple time points during the COVID-19 pandemic. Additionally, much research has not taken an intersectional approach to understanding the ways in which different facets of a resident's identity impact their wellness. Thus, more person-centred, probability-driven statistical approaches that can produce distinct heterogenous groups of individuals are warranted to understand the way in which different identities are associated with resident wellness scores.

METHODS: A latent profile analysis was conducted using institutional data from resident surveys administered from 2019 to …

Reflections Of Linguistic Experiences In A Borderland: Influences On Cultural Identity And Teacher Praxis, Iliana Cantu

Theses and Dissertations

This Autoethnographic dissertation uses autohistoria-teoria to critically analyze my lived curriculum as a Mexican-born raised in the borderland of the Rio Grande Valley. This research aims to understand the influence of my linguistic experiences on my cultural identity and teaching praxis within the same context. Drawing from Anzaldua’s (1987) concept of Borderlands as a contextual lens and Raciolinguistics as a theoretical framework, I examine and reflect on key linguistic experiences that have perpetuated colonizing linguistic practices rather than fostered linguistic diversity. Additionally, Culturally Linguistic Sustaining Pedagogy serves as a framework to critically analyze my teaching praxis in relation to my …

Barriers To Hispanic Post-Secondary Education In Science Fields, Luis Slayton

Theses and Dissertations

The study aimed to examine whether external barriers could be identified and are present throughout a Hispanic individual's educational life. The beliefs of the Hispanic community regarding education and the nature of acquiring an education could be relevant to the factors that impede the completion of high school. A survey approach was chosen as the methodology for the study due to the confidential nature of a questionnaire. Human nature tends to be more honest when not asked personal questions face-to-face. Additionally, there is potential to generalize attributes from a small sample to a larger population, allowing inferences about the identified …

Job Satisfaction And Vocational Services In Persons With Acquired Brain Injury, Claudia Eliza Gonzalez

Theses and Dissertations

The incidence of acquired brain injuries continues to rise world-wide resulting in increased disability status and national costs related to these injuries (Ahonle et al., 2020; BIAA, 2024; CDC, 2003; CDC, 2015; CDC, 2023; Grigorovich, et al., 2017; Tyerman et al., 2017). Long-term health effects associated with acquired brain injuries have social and environmental impacts that influence the individual with the injury beyond acute treatment and rehabilitation (Ahonle et al., 2020; CDC, 2023; Frieden et al., 2015; Grigorovich, et al., 2017; Tyerman et al., 2017). This, in turn, affects employment as many individuals with brain injuries are unable to return …

Exploring Intra- And Interpersonal Connection Through Mindful Moments At A Hispanic-Serving Institution, Yvette Angeline

Theses and Dissertations

The demands of contemporary education have contributed to high levels of stress, anxiety, and burnout among educators (Barton, 2019; Hidajat et al., 2023; Walker, 2022), uncovering a need for pedagogical approaches that prioritize holistic well-being and humanize the learning experience (Palmer, 2009; Salazar, 2013; Wong & Mishra, 2020).

The Impact Of Positive Psychology Use Upon Gls Outcomes For People With Chronic Pain Syndromes, Timothy Michael Curtis

Theses and Dissertations

The essence of being human is realized by our discovery of meaningful purpose throughout each important stage of our lives. If we perceive that we lack this meaningful purpose in our lives, it could become a distressful source of suffering to our sense of well-being emotionally, cognitively and perhaps, spiritually. A strong indicator of well-being comes from a good evaluation we ascertain as to how well we believe outcomes in our lives are consistent with our goals and values, which is also known as satisfaction with life. Research findings indicate that the more someone experiences repeated negative life events, the …

Arginine Vasotocin And Corticosterone In Nesting And Non-Nesting Loggerhead Sea Turtles In X’Cacel-X’Cacelito Sanctuary, Krista Blair Reed

Theses and Dissertations

Sea turtles exhibit distinct behaviors before and after egg laying, however, not all individuals successfully oviposit. Some females display disruptions in their typical nesting behavior, returning to the water without laying eggs, which is referred to as a non-nesting emergence (NNE). NNEs can be due to external disturbances on the beach, but why they occur is often unclear. Arginine vasotocin (AVT) is a neuropeptide involved in various physiological processes, including stimulating smooth muscle contraction of the oviduct to facilitate egg deposition in nesting sea turtles. On the other hand, corticosterone is the primary stress hormone in sea turtles and is …

Comparative Analysis Of Sequential And Non-Sequential Modeling Techniques For Ddos Attack Detection With Explainable Ai, Vincent Agbenyeavu

Theses and Dissertations

Cybersecurity is known today as one of the greatest challenges of the modern era. Among the various types of cyber-attacks that threaten our security, the Distributed Denial of Service (DDoS) attack is among some of the most common, effective, and well-recognized attack strategies. Since this form of attack is meant to disrupt the availability factor covertly, it can be detrimental to the targeted machines and difficult to discover. Because of that, there have been several approaches, as well as solutions that have been devised to detect it as accurately and efficiently as possible. In this study, four sequential data modeling …

Analyzing How Taste And Nutrition Impact Learning And Memory In Honey Bees Through Olfactory Associative Conditioning, Alessandra Elizabeth Perry

Theses and Dissertations

Honey bees detect sweet nectar, but not all sweet-tasting sugars provide nutrition. Unlike fruit flies, which can learn to avoid non-nutritious sweet foods, bees may lack this ability. To test if bees form caloric frustration memory (CFM), we conditioned them using odors paired with L-glucose (sweet but non-nutritious) or D-glucose (sweet and nutritious). Bees rewarded with L-glucose showed lower learning and long-term memory compared to D-glucose. Bees cannot differentiate between an odor associated with rewards containing malaise-causing compounds and an odor associated with a reward alone during differential conditioning. Therefore, we used differential conditioning to determine if lower acquisition in …
