Racial/Ethnic Disparities In Longitudinal Trajectories Of Arrest Probability After Traumatic Brain Injury, Mickeal Pugh Jr

Theses and Dissertations

Traumatic Brain Injury (TBI) is one of the leading causes of disability across the globe, and epidemiological studies have documented a rise in this condition over the recent years. Post-TBI functional impairments can persist beyond the acute phase of the injury, and specific psychosocial and injury-related factors have predicted variability in these outcomes. Previous literature has documented profound racial/ethnic disparities in TBI risk, cause, treatment, and rehabilitation. Prior investigation has revealed an overlap between incarceration and TBI, which showed that incarcerated persons typically endorsed a history of TBI. Criminal justice literature has shown stark racial/ethnic differences in incarceration rates, which …

Estimating Affective States In Virtual Reality Environments Using The Electroencephalogram, Meghan R. Kumar

Theses and Dissertations

Recent interest in high-performance virtual reality (VR) headsets has motivated research efforts to increase the user's sense of immersion via feedback of physiological measures. This work presents the use of electroencephalographic (EEG) measurements during observation of immersive VR videos to estimate the user's affective state. The EEG of 30 participants were recorded as each passively viewed a series of one minute immersive VR video clips and subjectively rated their level of valence, arousal, dominance, and liking. Correlates between EEG spectral bands and the subjective ratings were analyzed to identify statistically significant frequencies and electrode locations across participants. Model feasibility and …

Psychological Sense Of Community Among Older Adults In Puerto Rico Two Years After Hurricane María, Thomas D. Buckley

Hurricane María devastated Puerto Rico in 2017 and resulted in adverse long-term outcomes. Psychological sense of community (PSOC) may serve as a protective factor against the effects of Hurricane María for older adults in Puerto Rico. Using a three-paper format, this dissertation draws on a resilience framework and theories of PSOC and the Ecological Theory of Aging to examine the role of PSOC among older adults in Puerto Rico two years after Hurricane María.

Paper one is a scoping review of the concept of PSOC in research with community dwelling older adults. I begin by presenting findings on study characteristics …

Collaborative And Culturally Responsive Practices Of Transition Professionals To Support Black Students With High Incidence Disabilities, Amber Ruiz

Theses and Dissertations

Black students with high incidence disabilities have some of the most concerning postsecondary transition outcomes compared to their White and nondisabled peers (Awsumb et al., 2020; Hussar et al., 2020; Joint Legislative Audit and Review Commission [JLARC], 2020). Different government reports cited the lack of collaborative practices and various transition researchers imply the need for culturally responsive practices when supporting Black students (Federal Partners in Transition [FPT], 2015; Government Accountability Office [GAO], 2012; Thoma et al., 2016). To address these gaps in the literature, this study explored the collaborative and culturally responsive practices of transition professionals to support Black students …

The Role Of Community Belongingness In The Mental Health And Well-Being Of Black Lgbtq Adults, Keith Justin Watts

Theses and Dissertations

The impact of racial and sexual minority stigma, prejudice, and discrimination on the mental health and well-being of Black and LGBTQ individuals, respectively, has been well documented in the literature. Research on these relationships for Black LGBTQ individuals who are multiply marginalized due to their position at the social intersections of gender identity, sexual orientation, and race/ethnicity is less common. Belongingness to identity-based communities can protect against the negative impact of these minority stressors for Black and LGBTQ individuals and aid coping processes. However, Black LGBTQ individuals often experience stigma and discrimination in their racial, sexual, and gender minority communities …

A Case Of Misalignment Of Reasoning, Affect, And Performance In The Transition-To-Proof, V. Rani Satyam

Journal of Mathematics and Science: Collaborative Explorations

Learning how to prove is known to be difficult for undergraduate students. Understanding students’ growth in the multiple arenas that make up proving is crucial for supporting them. Across four interviews over a semester, I examine one student who showed growth in his reasoning but whose proofs were still incorrect, yet he showed high levels of positive affect including confidence throughout. Investigating this single-subject case serves as an example of the interplay between development and performance. The question of whether we can say this student is a better prover than before––fundamentally, how to weigh reasoning versus affect versus performance––motivates the …

Evaluation Of Five Methods To Develop Latent Prints On Thermal Paper, Jenna Pregent

Master of Science in Forensic Science Directed Research Projects

Forensic latent fingerprint laboratories determine the proper techniques for fingerprint visualization based on the substrates upon which they are deposited. Typical forensic analysis of thermal paper evidence involves the application of ninhydrin and/or 1,2-indanedione dissolved in a polar solvent. However, polar solvents create an undesirable reaction with the thermal paper’s internal properties and often lead to discoloration of the evidence. When this occurs, not only are the fingerprints less likely to be visible due to the loss of contrast, but the evidentiary print on the receipt may be lost entirely. This research sought to compare five development methods to determine …

Identification And Optimization Of Mirna Biomarkers For Body Mass Index (Bmi) Estimation In Forensic Samples, Jennifer J. Shealy

Master of Science in Forensic Science Directed Research Projects

DNA profiles do not provide as much evidentiary value when either all known samples can be excluded or when there is no known suspect. DNA phenotyping is a technique used for investigative purposes to predict externally visible characteristics (EVCs) based on specific markers found in the genome. Most phenotyping panels are currently restricted to markers stable over a lifetime within an individual and are not able to predict environmental or metabolic impacts on EVCs. It is known that miRNA expression levels change due to environmental and metabolic factors, such as BMI, and research has proven associations between circulating plasma miRNAs …

Victimization And Psychological Wellbeing Among Sexual And Gender Minority Emerging Adults: Testing The Moderating Role Of Emotional Comfort From Companion Animals, Jennifer L. Murphy, Camie A. Tomlinson, Angela Matijczak, Kelly O'Connor, Shelby Mcdonald

Graduate Research Posters

Introduction: Human-animal interaction science is a growing field, largely due to the potential psychosocial benefits companion animals provide to humans. One way companion animals may influence psychosocial outcomes is through their ability to provide emotional comfort, though few studies have examined relationships between sexual and gender minority stressors (i.e. discrimination, victimization, rejection), human-animal interaction, and psychological wellbeing. To address this gap in the literature, the current study evaluates whether, and to what extent, the association between gender-based victimization and psychological wellbeing (i.e., anxiety, depression, self-esteem) varies as a function of emotional comfort from companion animals among emerging adults.

Methods: Data …

Family Learning Culture Assessment: Development Of Metrics Of The Collective Epistemic Orientations And Achievement Motivations In Diverse Families, Catina Venning

Graduate Research Posters

The family, in educational psychology research, is unidimensional. It is either a covariate, a tool for school agenda or narrowly defined by a single person, usually the mother and her college educational attainment. These diminutions of family hamper efforts to fully understand critical contextual factors that impact student learning, like family. Inspired by Cultural Historical Activity Theory (CHAT) and Family Communication Practices (FCP), Family Learning Culture Theory (FLCT) emerged as the conceptual framework for a exploratory research project, which interviewed three middle-class family representatives, of high school students in two school districts in a Southeastern city in the United States. …

The Effect Of Self-Rated Health And Race/Ethnicity On The Relationship Between Feelings Of Content And Frequency Of Seeing Their Primary Care Provider, Alexandra Wynn, Kristina Beatrice Hood

Graduate Research Posters

Racial and ethnic minorities face significant health disparities as they are less likely to receive preventive health services, receive lower-quality care and have worse health outcomes for many chronic conditions than White people (Hostetter, Klein, 2018). Thus, it is important to analyze what psychological and social factors affect these populations and how they contribute to healthcare engagement. One psychological correlate that has not been focused on is self-rated health. Self-rated health has mainly been analyzed for its relationship with personality and physiological factors but little research has focused on how it influences seeking medical care. Fair/poor self-rated health was found …

Relations Between Sexual And Gender Minority Stress, Personal Hardiness, And Psychological Stress In Emerging Adulthood: Examining Indirect Effects Via Human-Animal Interaction, Camie A. Tomlinson, Jennifer L. Murphy, Angela Matijczak, Shelby E. Mcdonald

Graduate Research Posters

Introduction: Although there is emerging evidence that companion animals are important sources of comfort and support for many LGBTQ+ (lesbian, gay, bisexual, transgender and other sexual and gender minority identities) individuals, little is known about the interplay between sexual and gender minority (SGM) stress, human-animal interaction (HAI), and psychological adjustment in this population. To address this gap in the literature, the current study examined the role of HAI in relations between SGM stress (i.e., microaggressions, victimization) and psychological adjustment (i.e., self-efficacy, psychological stress) during emerging adulthood.

Methods: Our sample included LGBTQ+ young adults between the ages of 18 and 21 …

Background: There has been exponential growth in the number of direct-to-consumer genetic testing kits sold in the past decade. Consumers utilize direct-to-consumer genetic tests for a number of reasons which include learning about one’s ancestry and potential ways to manage health. Emerging adults tend to be early adopters of new technologies; however, there has been little research regarding the opinions about direct-to-consumer genetic testing in emerging adults.

Methods: Data came from a study conducted in an upper-level biology course focusing on understanding undergraduate science students’ overall experiences with receiving personalized genetic testing results from 23andMe. The present study used data …

The Association Of Menthol Cigarette Use With Any Mental Illness (Ami) And Serious Mental Illness (Smi) Among Us Smoekrs, Augustus White

Graduate Research Posters

ABSTRACT

Background: Mental illness affects 1-in-5 adults in the United States (US). Previously, those with mental illness have been shown to be 70% more likely to smoke cigarettes than the general population. However, little is known regarding whether the use of menthol cigarettes (one of only two available “characterizing flavors” of cigarettes) might impact the association between tobacco use and mental illness. Such information is critical in light of the disproportionately high rate of use of menthol cigarettes observed among African American smokers, as well as to inform recent legislative proposals that seek to ban the sale of menthol cigarettes. …

Cultural Socialization And Ethnic-Racial Identity Mediated By Positive And Negative Conversations About Race: Exploring Differences Among Students Of Color And White Students, Maria J. Cisneros, Eryn Delaney, Chelsea D. Williams, Sabrina Hawa, Chloe Walker, Fantasy Lozada, Su Jinni, Danielle Dick

Graduate Research Posters

Objectives: The current study examined associations between cultural socialization and ethnic-racial identity (ERI) via positive and negative conversations about one’s ethnicity/race. Differences between students of color (SOC) and White students (WS) were explored.

Method: Diverse college students 18-22 (M age = 18.46) participating in a university-wide study provided self-reports of childhood cultural socialization, engagement in conversations about ethnicity/race during college, and ERI.

Results: Cultural socialization was associated with more positive conversations about race, and, in turn, greater ERI exploration, resolution, and affirmation among SOC and WS. Additionally, negative conversations about race were associated with greater ERI exploration and …

Prolactin Drives A Dynamic Stat5a/Hdac6/Hmgn2 Cis-Regulatory Landscape Exploitable In Er+ Breast Cancer, Justin M. Craig

Theses and Dissertations

The hormone prolactin has been implicated in breast cancer pathogenesis and regulates chromatin engagement by the transcription factor, STAT5A. STAT5A is known to inducibly bind promoters and cis-regulatory elements genome-wide, though the mechanisms by which it exerts specificity and regulation of target gene expression remain enigmatic. We previously identified HDAC6 and HMGN2 as cofactors that facilitate prolactin induced, STAT5A mediated gene expression. Here, multi-condition STAT5A, HDAC6, and HMGN2 ChIP-seq with parallel condition RNA-seq are utilized to reveal the cis-regulatory landscape and cofactor dynamics underlying prolactin stimulated gene expression in breast cancer. We find that prolactin regulated genes are …
