Interictal Avoidance Of Sensory Stimuli Among Individuals With Migraine, Daniel Rogers

Electronic Theses and Dissertations

Migraine is the most debilitating neurological disorder worldwide and is associated with high economic and psychological costs. Common behavioral strategies for coping with migraine include avoidance of stimuli believed to precipitate an attack, though literature suggests that avoidance behaviors may serve to exacerbate migraine-symptoms and increase disability. Although the incorporation of trigger avoidance in modern conceptualizations of headache-related disability represents a more comprehensive understanding of disability occurring outside of migraine attacks (interictally), extant literature has emphasized trigger avoidance to the exclusion of other factors. Learning principles suggest stimuli that exacerbate migraine may take on similar eliciting properties as pain and …

Manipulations Of A Memory Interference Paradigm, Lindsay Kyle Crawford

Electronic Theses and Dissertations

The AB/DE, AC/FG paired associate learning task, which has been utilized in numerous experimental studies, is purported to induce both proactive (PI) and retroactive interference (RI) simultaneously. However, until now, there have not been any studies validating or determining the optimal format of this paradigm. As such, the purpose of this series of experiments was to make manipulations to the task in order to maximize its efficacy. Across the series of experiments implemented herein, we manipulated various aspects of the paradigm (e.g., semantic relatedness of the word pairs, number of trials) driven by theoretical underpinnings of memory interference theory. Experiments …

Rap1a Overlaps The Age/Rage Signaling Cascade In Type 2 Diabetes Mellitus, Stephanie Burr

Electronic Theses and Dissertations

Diabetic individuals have an increased risk for developing cardiovascular disease due to stiffening of the left ventricle, which is thought to occur, in part, by increased AGE/RAGE signaling. Advanced glycation end products (AGEs) accumulate within the body over time, and under hyperglycemic conditions, the formation and accumulation of AGEs is accelerated. AGEs exert their effect by binding to their receptor (RAGE) and can induce myofibroblast differentiation, oxidative stress, cell-extracellular matrix contraction, and cell migration. Previous findings from our lab have demonstrated that preventing the production of Rap1a, a Ras-like GTPase signaling protein, in cardiac fibroblasts will decrease type 2 diabetes …

Gestures Of Dissent: Self-Fashioning Performance From Southern Women Writers During The Fin De Siécle, Elisa Fuhrken

Electronic Theses and Dissertations

This project explores Southern women writers during the latter half of the nineteenth-century who asserted and crafted a modernized identity by turning to various modes of transgressive performance and performance spaces. For women of the nineteenth-century, this meant extricating themselves from a domestic, sentimental identity and apprehending a more fluid, dynamic type of being. The modes of performance, such as spectatorship, orality, and gesture, allowed these women to express and articulate an alternative feminine identity while also engaging with an embodied epistemology. This thesis looks at three Southern women writers: Sherwood Bonner’s novel Like Unto Like and her travel letters …

Methylene Blue As Light And Reactive Oxygen Species Sensitive Ligand: Appicability In Hybrid Drug And Material Synthesis, Huy Dao

Electronic Theses and Dissertations

Methylene blue (MB) with a 10-N-carbamoyl linkage was discovered and developed as a multifunctional far-red (660 nm) photocleavable ligand capable of rendering a series of MB conjugated compounds with off-to-on fluorescence switch properties through the controlled release of MB. The released MB was successfully demonstrated to be an effective photosensitizer, imaging probe, and therapeutic agent. The complete release of MB was achieved with a cumulative light dose of 15 J/cm2. The photosensitivity was demonstrated to be dependent on the type of chemical bond at 10-N of the phenothiazine ring which links MB to a side group. Specifically, the urea bond-based …

This study analyzes the implementation of two elements: engaging teachers in a book study on culturally responsive teaching strategies and targeted counseling …

The Role Of Social Anxiety In Prosocial Behavior Following Exclusion, Hannah Friedman

Electronic Theses and Dissertations

Social anxiety (SA) causes significant distress and impairment in several areas of daily life. Individuals with SA experience increased rates of exclusion and have more difficultly forming meaningful interpersonal relationships. Exclusion is associated with increased SA and motivations for social withdrawal in emerging adulthood. In non-SA individuals, the desire for compensatory social interaction following exclusion often produces prosocial behaviors (e.g., increased effort to help the group). Prosocial behavior levels following exclusion are not uniform, however, as an individual’s response may vary depending on the type of exclusion experienced. Although previous work has observed decreased levels of prosocial behavior in non-SA …

1.5 Generation Korean-American Young Adults' Bilingualism And Their Identity In The U.S., Hanna Kim

Electronic Theses and Dissertations

Since the 20th century, particularly post-1965, there has been rapid growth in the Korean-American population in the U.S. The number of 1.5 generation Korean-Americans has also increased. 1.5 generation Korean-Americans can take advantage of learning both languages and cultures in the two countries which can help them become bilingual and bicultural individuals. However, previous studies about the language experience and identity of Korean-Americans have mainly focused on the first or second-generations (Kang, 2013; M. Park, 2005) rather than 1.5 generations. Some of these studies have focused more on children at an early age (E. S. Park, 2005; Zhou, 1997) instead …

Electronic Theses and Dissertations

This study examines the effects of non-native phonotactic constraints on the perception of nasal-initial consonant clusters (NICC), specifically whether native English speakers can perceive NICC as accurately as native Swahili speakers. The ABX task was conducted over Zoom to test L1 English speakers (N=12) and L1 Swahili speakers (N=12). Stimuli with four conditions were used: 1) The stimuli had one of the three nasal sounds (/m/, /n/, and /?/) in word-initial consonant clusters; 2) The stimuli had NICC composed of a nasal sound followed by either a voiced or voiceless consonant; 3) The consonant clusters were composed of sounds that …

The Trajectory Of Resilience, Meaning In Life, Social Support, Posttraumatic Growth, And Posttraumatic Stress For Emerging Adult Trauma Survivors, Marcela C. Weber

Electronic Theses and Dissertations

BACKGROUND: The literature suggests the relationship between posttraumatic growth (PTG) and posttraumatic stress (PTS) is curvilinear, and that type or severity of trauma may affect this relationship. The relationship between depression, anxiety, and PTG is understudied. It is well established that meaning in life predicts PTG, PTS, and resilience, yet most of the research has measured general perceived meaning rather than meaning beyond-the-self, specifically, which was initially theorized by mid-century Humanistic psychologists. Mixed findings about whether searching for meaning is beneficial or harmful suggests potential moderators of search for meaning should be explored. METHOD: Participants (N = 628) were emerging …

The Perceptions That Um First-Generation College Students Have Regarding The Impact Of Campus Engagement On Their Success At The Institution, Martin B. Fisher

Electronic Theses and Dissertations

First-generation students are often underprepared for college and have lower persistence rates (Balemian & Feng, 2013), and they face a unique set of challenges in their transition to college that many of their peers do not (Pelco, Bell, & Lockeman, 2014). Consistent with national statistics, data obtained from UM’s Office of Institutional Research, Effectiveness, and Planning indicate first-generation students at UM persist and graduate at lower rates than their peers whose parents have a bachelor’s degree.

There are many reasons why first-generation students have lower success rates, and, for some students, a lack of engagement is one of them (Pascarella, …

Navigating Internalized Stigma And Identity Development In Bipolar Disorder I: A Grounded Theory Investigation., Kaylyn L. Watterson

Electronic Theses and Dissertations

Mental illness stigma occurs at multiple levels in Western societies. Internalized stigma, the application of negative stereotypes and prejudice about mental illness to self-concept, has deleterious effects on mental health for adults living with a serious mental illness. Historically, research on stigma in serious mental illness has centered on schizophrenia. Recently, researchers and clinicians have drawn attention to bipolar disorder I, an affective disorder that creates disruptions in functioning and increased risk for substance abuse and suicide. Despite the growing literature establishing the relationship between recovery in serious mental illness and identity, little is known about how adults in long-term …
