Effects Of Violent And Nonviolent Life Stressors Among Urban Early Adolescents: Testing Competing Models Of Comorbid Distress And Externalizing Symptoms, Erin Thompson

Theses and Dissertations

The strong association between stressful life events and the wide-ranging spectrum of psychopathology has led some to advocate for the reconceptualization of traumatic stress. There has been a longstanding debate on whether these symptoms are best represented by using dimensional versus categorical approaches. Moreover, further understanding of the risk factors associated with various dimensions or patterns of comorbid emotional and behavioral problems could inform future research and intervention efforts. The current study tested competing variable- and person-centered approaches and examined how stressful life events are associated with different patterns of distress and externalizing symptoms among a predominantly African American and …

College Students’ Perceptions Of Popular Diets And Orthorexia Nervosa, Madison W. Weinstock

Theses and Dissertations

Data suggest that individuals’ purported dietary patterns influence others’ perceptions of them. However, few studies have investigated how adherence to specific popular diets might influence these perceptions. This study investigated female undergraduates’ (n = 463) perceptions of vignette characters described as adhering to specific dietary practices perceptions of a vignette character in a sample of 463 female undergraduates. Characters described as adhering to a Clean Eating diet were viewed most positively, followed by individuals on the Ketogenic diet or nondieters. Characters following an Intermittent Fasting diet, and those with Orthorexia Nervosa were viewed most negatively. These findings support the …

Acute Stress Disorder In Neonatal Intensiver Care Unit Mothers: Modeling Risk Factors And Trauma Appraisals Modeling, Allison Baylor 5435882

Theses and Dissertations

Postpartum mental health is a public health priority, particularly for mothers with infants in the Neonatal Intensive Care Unit (NICU), who may have experienced a precipitous birth, followed by a traumatic NICU hospitalization. However, little research has focused on NICUrelated posttraumatic stress (PTSS), despite its presumed prevalence and ripple effects on infant development, family functioning, and provider burnout during the critical early bonding period. In particular, little research has evaluated: early posttraumatic stress (Acute Stress Disorder symptoms, ASD), index and sequential traumas related to NICU/birth, and relations among preexisting risk factors, and trauma appraisals/ objective trauma characteristics (related to infant …

Developmental Trajectories In Cannabis Use: Predispositions, Peers, And Activity Participation, Nathaniel S. Thomas

Theses and Dissertations

This study examined the overall and conditional influences of a polygenic score for cannabis initiation, various forms of activity participation, peer deviance, and time on recent cannabis use. Data came from a longitudinal sample of undergraduate college students and was stratified into European American (N_EA=3010) and African American (N_AA=1308) subsamples for genetic analyses. Engagement with church activities predicted lower probability of cannabis use. Peer deviance predicted higher probability of cannabis use Engagement with community activities moderated in the influence of the polygenic risk score in the EA subsample, such that any level of engagement with community …

Relationships Among Parkinson’S Disease Symptoms, Stigma, And Mental Health: A Strengths-Based Perspective, Richard S. Henry

Theses and Dissertations

As rates of Parkinson’s disease (PD) increase, so does the need to examine some of the negative social consequences experienced by people with PD. Symptoms of PD have been linked to greater experiences of stigma, and the more visible symptoms of PD increase an individual’s likelihood for experiencing stigmatization and social rejection. Individuals who experience high levels of stigma generally have poorer mental health outcomes. While these relationships are well documented, little is known about whether stigma mediates the relationship between PD symptoms and mental health outcomes. Additionally, some past research suggests that the personal strengths of social support and …

A Critical Multiple Case Study Analysis Examining The Implementation Of The Every Student Succeeds Act (Essa) To Promote Positive School Climate, Weade W. James

Theses and Dissertations

This study explored the role of federal policy in improving school climate, and examined how federal policy, specifically the Every Student Succeeds Act (ESSA) is being implemented at the state-level to address school climate issues. A qualitative multiple-case study design with content analysis was used as the leading approach to understanding how states are implementing ESSA’s school climate measure for accountability. ESSA is the nation’s federal education law that was enacted in 2015 and replaced No Child Left Behind (NCLB). I compared states’ implementation of ESSA’s school climate and safety (SCS) measure, including how states are measuring SCS and whether …

Bidirectional Associations Between Passive And Active Technology Use And Sleep: A Longitudinal Examination In Young Adolescents With And Without Adhd, Elizaveta Bourchtein

Theses and Dissertations

Many adolescents do not receive recommended amounts of sleep, and prevalence rates of sleep problems are particularly high among adolescents with attention-deficit/hyperactivity disorder (ADHD). One factor that may contribute to these sleep difficulties is technology use, and there is some evidence that the association between technology use and sleep may be bi-directional. Further, type of technology use (i.e., passive versus active) may be differentially associated with sleep. To date, most studies have evaluated these associations cross-sectionally and relied upon global and subjective ratings of technology use and sleep, which masks important day-to-day variability. The present study evaluated bi-directional associations between …

Sleep Behaviors And Thoughts As Links Between Social Rhythmicity And Mental Health Outcomes, Sahar Sabet

Theses and Dissertations

Social rhythmicity refers to the regularity with which one engages in social and lifestyle activities. Considerable research has recognized that social rhythms have important implications for health and well-being. For example, disturbances in social rhythms are one potential factor that may contribute to the development of anxiety and depressive disorders. Existing research on social rhythm irregularity has heavily focused on its link with bipolar disorder and, to a lesser extent, with depression. Less is known about the association of social rhythms with anxiety or with subclinical levels of depression. Furthermore, it is unclear how social rhythms are tied to mental …

Validation Of Ninein As An Ethanol-Related Quantitative Trait Gene: Reassessment, Design, And Functional Validation Of Reference Genes For Qpcr Analysis Of Brain Tissue In Mice, Jessica L. Jurmain

Theses and Dissertations

The increasing use of quantitative real-time polymerase chain reaction (qPCR) as a method for quantifying gene expression has led to an increased demand for standardization of data analysis methods to ensure accurate reporting and robust, reproducible results. The exponential nature of qPCR amplification results in the potential magnification of what are usually very small sources of error. Relative gene expression calculations circumvent this issue by normalizing target gene expression data to within-sample expression of a previously validated, stably expressed reference gene or genes. Multiple studies discussed herein have found that qPCR data are more reliable and reproducible when multiple reference …

From Small Beginnings To Large-Scale Harm: On Demagoguery And Misogyny In The Classroom And Writing Center, Shannon Roberson

Theses and Dissertations

My project is grounded in the rhetorical concept of aretê—excellence or virtue—as it relates to education and educational spaces within demagogic and misogynist cultural forces. The problems of demagoguery and misogyny stem from small-scale perpetuation of agonistic norms that go unaddressed in U.S. culture, a culture that is deeply identity-driven. These forces persist on social media platforms and within patriarchal systems of education.

For my project, I suggest rhetorical media literacy education of small-scale demagoguery moments on social media as a way to bring awareness to larger-scale events. On a micro-scale, social media influencers cultivate behaviors that mimic demagogic …

Quantification And Modeling Of Bladder Biomechanics Mechanisms Linking Spontaneous Rhythmic Contractions And Dynamic Elasticity To Detrusor Overactivity, Zachary E. Cullingsworth

Theses and Dissertations

Overactive bladder (OAB) is a chronic condition affecting approximately 20% of adults in the United States. Detrusor overactivity (DO) is the presence of non-voiding contractions in the detrusor (bladder) muscle during filling and is present in some individuals with OAB. DO is currently identified visually during a urodynamics (UD) study involving pressure catheters and filling and voiding of the bladder to evaluate function. UD provides limited subtyping of DO, and an incomplete understanding of mechanisms contributing to OAB.

Aim 1 of this study was to develop objective tools to quantify, subgroup and better understand …

The Moderating Role Of Developmental Assets On Relations Between Child Maltreatment, Trauma, And Dating Violence, Stephanie A. Hitti

Theses and Dissertations

Teenage dating violence (TDV) is prevalent and associated with an array of psychosocial and health problems. Thus, numerous studies have focused on the identification of risk and protective factors for TDV. Child maltreatment has been consistently identified as a risk factor for TDV victimization and perpetration. However, potential underlying mechanisms that may partially explain the relations between child maltreatment and TDV victimization and perpetration are not well understood. The present study explored indirect relations between child maltreatment and TDV victimization and perpetration via trauma symptoms, and examined whether internal and external developmental assets moderated relations between (a) child maltreatment and …

Integrative And Contextual Learning In College Algebra -An Interdisciplinary Collaboration With Economics, Choon Shan Lai, Glenn Henshaw, Tao Chen, Soloman Kone

Journal of Mathematics and Science: Collaborative Explorations

Many students consider mathematics too abstract and useless for their academic and career goals. Meanwhile, instructors in quantitative disciplines such as economics find many students mathematically underprepared for their courses. The disconnect between students’ perceptions of the utility of mathematics and their life and career may have contributed to some of the under-performance in learning mathematics. Addressing this problem requires collaboration across disciplines to develop an understanding of each other’s needs, more specifically to develop an integrative platform that allows students to apply mathematical skills in interdisciplinary contexts (Ganter & Barker, 2004). We collaboratively designed and implemented an integrative platform …

Work Hope And Work Volition: Exploring The Influence Of Community College Students’ Rurality And Socioeconomic Status, Jesse A. Wingate

Theses and Dissertations

Data from a sample of community college students (N = 478) in Virginia were used to examine relations among rurality, socioeconomic status, work hope, and work volition. Socioeconomic status, work hope, and work volition were positively associated. However, rurality, measured both as a continuous and categorical variable, was not correlated with work hope or work volition. Additional analyses showed convergence between measures of work hope and work volition confirming construct similarity. Results, limitations, implications, and recommendations for future study are included.

Preventative And Therapeutic Effects Of Bmsc Exosome On Periodontal Disease, Jin Ha Kim

Theses and Dissertations

Periodontitis is an inflammatory disease caused by the imbalance between host immune response and bacterial infection. Strategies to manage the uncontrolled, excessive immune response and to promote tissue healing are in great demand. Therapies based on mesenchymal stem cells (MSCs) are promising and the clinical effects of MSCs are largely mediated by their secretome, especially exosomes. Previously, we isolated and purified exosomes secreted by human bone marrow mesenchymal stem cells (hBMSC). These exosomes have proliferative, chemotactic, anti-inflammatory and anti-osteoclastic function in vitro. In this study, we had two hypotheses: 1) hBMSC exosomes would prevent periodontal inflammation and alveolar bone loss …

Unpacking "Giftedness": Research And Strategies For Promoting Racial And Socioeconomic Equity, David B. Naff, Genevieve Siegel-Hawley, Amy Jefferson, Michael Schad, Morgan Saxby, Kathryn Haines, Zoey Lu

MERC Publications

Giftedness as a construct continues to be contested in academia, in the classroom and around kitchen tables. It means different things to different communities and, as a result, acquiring the "gifted" label looks different around the country. Once labeled, student giftedness produces different responses depending on state and district guidelines. A constant among the patchwork of defining, identifying and responding to student giftedness, though, is a serious racial and economic disparity in who is considered gifted and who is not. This report provides key takeaways from research literature on gifted and talented (GT) programs. It is organized according to five …
