The Impact Of Eye-Movement Desensitization And Reprocessing On Self-Reported Test Anxiety In College Students, Renee Wilson Dec 2023

The Impact Of Eye-Movement Desensitization And Reprocessing On Self-Reported Test Anxiety In College Students, Renee Wilson

Graduate Theses and Dissertations

Test Anxiety (TA) has become a major concern for college students. Experiencing mental concern about test-taking perpetuated by physiological hyperarousal directly affects students’ ability to be successful in college. Eye Movement Desensitization and Reprocessing (EMDR) is a multi-faceted therapeutic approach that aims to process dysfunctional negative cognitions which originate with negative past experiences to an adaptive state. Developed by Francine Shapiro in 1989, the Adaptive Information Processing (AIP) model undergirds the 30-second, therapist-initiated, bi-lateral eye-movements. These movements identify and reprocess emotionally disturbing experiences, linked to an individual’s emotional expression, by deliberatively triggering a connected trauma network. This dissertation examined the …


A Mixed-Methods Exploration Of Emergency Service Use In Autistic Youth And Young Adults, Rebecca S. Bradley Dec 2023

A Mixed-Methods Exploration Of Emergency Service Use In Autistic Youth And Young Adults, Rebecca S. Bradley

Graduate Theses and Dissertations

Autistic youth are at an increased risk for needing emergency services as compared to neurotypical peers. In fact, approximately 20% of autistic youth will interact with police by the age of 21, and rates of emergency department visits are 30 – 70% higher among autistic individuals than neurotypical peers. While research has begun to explore the nature of emergency service use in this group, researchers have not yet assessed important individual-, family-, and community-level factors that may be associated with these encounters. This study aimed to address this gap in the field by 1) characterizing families of autistic children who …

Examining The Hormonal Underpinnings Of Affiliation Motivation In Oral Contraceptive Users, Hormonal Iud Users, And Naturally Cycling Women, Mikayla Tolliver

Graduate Theses and Dissertations

Affiliation is important for women during times of stress. Although, affiliation has been linked to women’s hormones across the menstrual cycle, many women use hormonal contraceptives which disrupt the links between hormones, psychology, and behavior. This study examined how hormonal contraceptives (hormonal IUD vs. the oral contraceptive pill) and menstrual cycle phase (follicular vs. luteal) are associated with affiliative motivations following the Trier Social Stress Test (TSST). Further, this study examined women’s cortisol reactivity and whether cortisol reactivity mediated affiliative motivation following the stressor. I found that oral contraceptive pill users projected more stress and rejection onto others’ faces and …


Deep Learning Frameworks For Accelerated Magnetic Resonance Image Reconstruction Without Ground Truths, Ibsa Kumara Jalata Dec 2023

Deep Learning Frameworks For Accelerated Magnetic Resonance Image Reconstruction Without Ground Truths, Ibsa Kumara Jalata

Graduate Theses and Dissertations

Magnetic Resonance Imaging (MRI) is typically a slow process because of its sequential data acquisition. To speed up this process, MR acquisition is often accelerated by undersampling k-space signals and solving an ill-posed problem through a constrained optimization process. Image reconstruction from under-sampled data is posed as an inverse problem in traditional model-based learning paradigms. While traditional methods use image priors as constraints, modern deep learning methods use supervised learning with ground truth images to learn image features and priors. However, in some cases, ground truth images are not available, making supervised learning impractical. Recent data-centric learning frameworks such as …

Characterization Of Highly Doped N-Type And P-Type Silicon Carbide Ohmic Contacts, Tanner Rice Dec 2023

Characterization Of Highly Doped N-Type And P-Type Silicon Carbide Ohmic Contacts, Tanner Rice

Graduate Theses and Dissertations

Silicon Carbide (SiC) is a rather new material that possesses unparalleled properties when compared to Silicon. Due to its larger band gap alongside other thermal properties, SiC can survive in hotter, more radiation intensive environments, whether that be within the crust of the earth or in the reaches of space. As a desirable semiconductor for these applications, CMOS is an especially important device due to its low power consumption. However, creating a good contact between the metal and semiconductor optimally requires two different metals for the n -type and the p-type semiconductor. This greatly increases the processing time, as separate …


The Spatial And Temporal Distribution Of Large Rock Blocks And Control On Landscape Evolution In The Ozarks, Chelsea Moran Dec 2023

The Spatial And Temporal Distribution Of Large Rock Blocks And Control On Landscape Evolution In The Ozarks, Chelsea Moran

Graduate Theses and Dissertations

Geologists often use landscape form to infer landscape processes through time. While climate and tectonics shape geomorphic form, the potential range of spatial or temporal scales that can shape any specific landscape can render landscape process-form based hypotheses too general for consideration. Contributions by mathematical modeling have helped bridge the gap between inferring processes from form, notably in how sediment transport dynamics shape hillslopes. However, few models encapsulate the movement of large rock blocks ( >2 meters across) and their potential impact as hillslope sediment transport disruptors. The Upper Buffalo River watershed (BRW) in the Ozarks of northern Arkansas has …

Examining The Relationship Between Student Age And Modality Choice In A Community College’S New Student Orientation Program: A Preregistered Study To Examine The Assumption Of Self-Directed Learning, Amy L. Foree

Graduate Theses and Dissertations

Abstract Understanding and navigating college rules, resources, and expectations is a considerable barrier for students accessing and transitioning to college (Conley, 2007; Williams, 1996; Hooker & Brand, 2010; Ardoin, 2013; Sheppard, 2012). To improve students’ acquisition of pertinent, time-sensitive information, many institutions have implemented mandatory new student orientations (NSO). Orientations provide information such as academic policies and procedures, institutional expectations, campus resources, and financial aid assistance. They also allow students to meet faculty, staff, and other new students. By providing these resources, institutions acclimate students to their new environment. Although colleges realize that new student orientations support students’ success, they …

Human-Bat Interactions In A Disease Emergence Hotspot: Implications For Human Health And Bat Conservation, Reilly Tempest Jackson Dec 2023

Human-Bat Interactions In A Disease Emergence Hotspot: Implications For Human Health And Bat Conservation, Reilly Tempest Jackson

Graduate Theses and Dissertations

Bats are an ecologically important taxon that can host zoonotic pathogens. Globally, many bat species are synanthropic and live closely with humans, often roosting in man-made structures. The spatial overlap between humans and bats creates opportunities for human-bat contact, which can lead to human exposure to bat-borne pathogens and conflicts that cause bat mortality. Despite this risk, little is known about the drivers and characteristics of these human-bat interactions in buildings and work is needed to understand this aspect of the wildlife-urban interface. In Chapter I, I present a literature review that identifies the geographic and taxonomic trends in reported …

Development Of A Historic Digital Elevation Model (Hdem) From Archival Aerial Imagery Over The Black Mountain Alluvial Fan, Canada, Emma Menio

Graduate Theses and Dissertations

In a rapidly changing Arctic, reconstructing landscapes pre-warming is essential to understanding impacts due to climate-inducted geomorphic change. High-latitude elevation datasets extend temporally back to the 2000s, while region-wide warming became measurable in the 1980s. Historic aerial imagery archives provide datasets of high-resolution imagery from the mid- to late- 1900s with stereo-capability that can be harnessed to create historic digital elevation models, or hDEMs. A major issue with reconstructing a surface from the past is finding a way to constrain it in space, given a lack of ground control from that era, especially at high latitudes. The main purpose of …


Age, Size, And Composition Of Selected Old-Growth Shortleaf Pine Stands In The Upper Buffalo River, Arkansas, Willa Avery Thomason Dec 2023

Age, Size, And Composition Of Selected Old-Growth Shortleaf Pine Stands In The Upper Buffalo River, Arkansas, Willa Avery Thomason

Graduate Theses and Dissertations

Shortleaf pine (Pinus echinata) approaches the westernmost limits of its range in the Arkansas Ozarks. Despite heavy logging of shortleaf pine throughout its range during the 19th and 20th centuries, the species was not easily accessible for harvest and transportation in the most rugged areas of the Boston Mountains and, as a result, there are a few extant stands of old-growth shortleaf pine in the region. The shortleaf pine stands in the interior Boston Mountains are unusual in that they exist primarily above bluff lines at topographic breaks in the hardwood canopy and are not disturbed by fire as frequently …
