Resting Autonomic Activity, Emotional Reactivity, And Executive Function In Preschool-Age Children Who Stutter, Dana J. Meyerson

Theses - ALL

Purpose: This study investigated whether preschool-aged children who stutter (CWS) differ from children who do not stutter (CWNS) in autonomic physiological reactivity and regulation during a phrase-repetition task paired with affective image-viewing conditions. Additionally, the study investigated whether individual differences in executive function skills, specifically inhibitory control, predicted variability in physiological responses across participants. Methods: Forty-three preschool-aged children (18 CWS, 25 CWNS) completed three laboratory visits that involved collection of electrocardiogram (ECG) recordings at rest and during a phrase-repetition task paired with visual stimuli of either neutral (fixation cross) or negative (IAPS) emotional valence. Inhibitory control was assessed using the …

Intersectionality, Epistemic Injustice, And Silencing: The Operationalization And Reification Of Intersectionality In Academic Research And Institutional Practices, Emery Lockwood

Theses - ALL

Intersectionality is a powerful analytic tool that can be used to better understand the role that oppression plays in society and how it shapes the way people affected by multiple systems of oppression interact with society. Recently, the unit of analysis for intersectionality has started to shift from intersecting systems of oppression to overlapping identities, which has changed intersectionality from being a tool used to analyze systemic oppression to individual’s experiences. This work explores the implications this shift has on academic research and the practice of several disciplines. Using a lens of epistemic injustice through theories of hermeneutical bastardization (Drury, …

Longitudinal Association Between Sleep Disturbance And Disordered Eating In Adolescents: The Mediating Role Of Emotion Dysregulation, Antonia Louise Hamilton

Theses - ALL

Accruing evidence suggests a significant relationship between sleep disturbances and disordered eating. Early adolescence is a period of heightened vulnerability for sleep disturbances and disordered eating. However, the longitudinal relationship between sleep disturbance and disordered eating remains unclear in early adolescent samples. The current study aims to examine if sleep disturbance longitudinally predicts disordered eating in early adolescents three years later, how the odds of having clinically significant disordered eating change per each unit increase in sleep disturbance, and if emotion dysregulation mediates these relationships. It is hypothesized that baseline sleep disturbance will predict greater disordered eating at follow-up, and …

Novel Origin Of Sperm Heteromorphism In The Drosophilidae, Karan Bhatt

Theses - ALL

Sperm heteromorphism, the production of two or more discrete sperm types or morphs within a single testis, occurs in diverse taxa. This phenomenon is believed to represent a division of labor by male gametes, with only one morph (the "eusperm") participating in fertilization and the other morph(s) specialized to perform some other (typically unknown) function within the female reproductive tract. One of the most intensively investigated systems is the Drosophila obscura species group, for which sperm heteromorphism evolved once in the common ancestor to the group, with all examined descendent species exhibiting sperm length heteromorphism. The absence of additional sperm …

Exploring The Role Of Astrocyte System Xc– In Excitatory/Inhibitory Balance, Samantha Olivia Sutton

Theses - ALL

Astrocytes play a central role in maintaining excitatory/inhibitory (E/I) balance in the central nervous system by supporting intracellular glutathione (GSH) synthesis and regulating extracellular glutamate. System xc– (Sxc–), an obligate cystine/glutamate antiporter encoded by SLC7a11, couples the import of L-cystine with the export of L-glutamate. It is highly expressed throughout the cortex, hippocampus, striatum, and cerebellum, where its activity provides cystine—the rate-limiting substrate for cysteine-dependent GSH production—and contributes to ambient glutamatergic tone. Although global loss of Sxc– alters seizure threshold and redox homeostasis, whether these effects arise specifically from the loss of astrocytic Sxc– has remained unresolved. This thesis examined …

Investigating The "Tend-And-Befriend" Stress Response As A Risk Factor For Sexual Victimization Among College Women, Emily Kathleen Presutti

Theses - ALL

Sexual victimization of college women is a significant public health concern on U.S. college campuses. Traditional research on the human stress response has focused on the "fight-or-flight" model, which may not adequately capture female-typical responses in stress-inducing situations. Using a mixed-methods design, we sought to determine whether the "tend-and-befriend" stress response serves as a potential correlate of sexual victimization among college women and examine whether it contributes additional variance beyond established correlates of sexual victimization such as alcohol use, history of sexual victimization, and involvement in campus party culture. The study was conducted in two phases. In Phase I, 128 …

Operational Context's Impact On Cockpit Behavior: Case Studies In Aviation, Nick Mehrdad Loghmani

Dissertations - ALL

This thesis examines instances where pilots in a tightly regulated environment, the modern airline cockpit, exhibit diverging responses when presented with identical information. Despite explicit standardization of procedures, instrumentation, and Crew Resource Management, observable patterns of operational divergence persist. The study adopts distributed cognition (Hutchins, 1995) as the primary lens and analyzes the crew–procedures–artifacts system using cockpit transcripts and flight data. Operational context is the evolving set of roles, procedures, cognitive artifacts (including automation), constraints, and environmental conditions, while the operational configuration denotes its time-indexed instantiation at moment t. Within this frame, the thesis documents when cues do—and do not—propagate …

Hepatocyte-Specific Lrp1 Silencing Exacerbates Brain Amyloidosis Without Compensatory Ldl Receptor Family Involvement, Brian Carson, Josephine Chu, Devaraj V. Chandrashekar, Jerome Garcia, Rachita K. Sumbria, Derick Han

Pharmacy Faculty Articles and Research

Background

LDL receptor related protein 1 (LRP1) is a major hepatic receptor involved in lipoprotein metabolism, protease degradation, transmembrane receptor modulation, and clearance of excess protein, such as Aβ. Decreased expression of LRP1 due to liver injury can impair receptor-mediated clearance, increasing Aβ availability in the periphery. We investigated the effects of hepato-specific silencing of LRP1 on Aβ deposition in the brain. Additionally, other LDL family members (LRP5, LRP6, and LDLR) that may participate in Aβ clearance were monitored in the liver to ensure non-compensatory effects of LRP1 silencing.

Method

4-month-old male double transgenic (APP/PS1) AD mice were injected with …

Policies Of Pain: Neoliberal Rhetorics Of The Opioid Epidemic In Culture And Policy, Gina Arlene Stinnett

Dissertations - ALL

This dissertation outlines and examines the Neoliberal rhetorics of choice and responsibility, and how these rhetorics are utilized in policy and culture related to the Opioid Epidemic in the United States. Through this examination of neoliberal rhetorics in policy and culture, I unpack the circular influence these two have on each other—i.e., cultural assumptions inform policy decisions, and established policy can slowly influence cultural assumptions. The key area in which these two influence each other is through rhetoric, therefore I argue that in addition to an economic and cultural structure, neoliberalism is a rhetorical structure—it shapes our society specifically through …
