"The First Fruits Of A Woman's Wit": Reclaiming The Childbirth Metaphor In Aemilia Lanyer's Salve Deus Rex Judaeorum, Carolyn Mae Shakespear

Theses and Dissertations

The childbirth metaphor adopts imagery from female bodies carrying and delivering children to describe the effort and relationship of a poet to his/her poem. This was a commonly used trope in the renaissance, particularly by male authors. This thesis examines the way early modern woman poet, Aemilia Lanyer uses the childbirth metaphor in her poem, Salve Deus Rex Judaeorum. Lanyer ultimately considers not only the physical realities of childbirth in her use of the metaphor, but also the emotional, social, and theological consequences. By doing so, I argue that Lanyer reclaims the metaphor from her male contemporaries in order to …

The Role Of Caloric Intake On Achilles Tendon Health In Pre-Professional Ballet Dancers, Annie G. Smedley

Theses and Dissertations

Background: Achilles tendinopathy is a common and debilitating condition among female ballet dancers due to the large repetitive loading forces placed on their Achilles tendons during rehearsals and performances. Tendon health problems in females are exacerbated by a lack of understanding about how energy availability influences tendons. Ballet dancers, as aesthetic athletes, are vulnerable to low energy availability and can enter a spectrum disorder, relative energy deficiency in sport, that consists of low energy availability (with or without disordered eating), menstrual cycle dysfunction, and low bone mineral density (BMD). Aims: 1) To investigate the relationship between insufficient caloric intake and …

Catchment Water Storage Mediates River Flow Sensitivity To Climate Change, Brian Charles Brown

Theses and Dissertations

As patterns of precipitation and evapotranspiration change, human water security and aquatic ecosystem health depend on understanding how catchment characteristics interact with climate to control river flow. We tested factors that mediate sensitivity of river flow to fluctuations in climate using a set of 1,148 data-rich, climate diverse catchments in various parts of the world from 2001-2020. We extrapolated these results to an additional 2,012 catchments with sparser data. Using features such as vegetation, land use, hydrology, and local climate, we found that catchments with high aridity to runoff ratios (Fuh's parameter) had 380% higher runoff sensitivity to fluctuations in …

The Relationship Of Self-Determination And Self-Construal On College Adjustment, Rayhane Baniardalan

Theses and Dissertations

This study investigated the interplay between self-construal (individualistic vs. collectivistic), basic psychological needs (autonomy, competence, relatedness), and college adjustment among a diverse student population. Contrary to expectations, self-construal did not directly predict overall adjustment. However, horizontal individualism (valuing personal achievement over group success) was negatively associated with adjustment. Supporting self-determination theory (SDT), all three basic psychological needs were positively correlated with all three domains of college adjustment (academic, social, and psychological). The strongest correlations were between relatedness and social functioning, and competence and social functioning. Racial differences in adjustment could not be examined due to sample limitations. Interaction effects between …

The Evaluation Of Non-Specific Risk Indicators In Improving Detection Of Psychosis-Spectrum Liability, Thomas W. O'Kane

Theses and Dissertations

Psychosis-spectrum disorders remain a leading cause of disability for both individuals and society, with early identification and prevention efforts representing a promising avenue of research for addressing these concerns. One potential impediment to improving early risk identification is the historical focus on indicators thought to be exclusive to the psychosis-spectrum. This focus often comes at the expense of non-specific risk factors (e.g., disrupted sleep, adverse childhood experiences) which contribute to the risk of developing psychosis as well as other mental illnesses. Research suggests the inclusion of these non-specific factors may improve our ability to identify those at risk. The present …

Perceptions Of Violent Content And Their Relationships On Aggressive Behavior: The Effects Of Implicit Beliefs On Aggression In Relation To Video Content, Logan Mccombs

Theses and Dissertations

Previous research shows that consuming violent media can lead to increased aggression in thoughts, feelings, and behaviors. Several other factors also contribute to such behaviors but have not been thoroughly studied including implicit beliefs about aggression in relation to media content. This two-part study consists of (1) an exploratory iterated principal-factor method to create an implicit belief measure about consuming violent media in conjunction with correlational analyses and (2) between subjects hierarchical linear regression models to determine what effects implicit beliefs have on subsequent aggression after participants view either a violent of nonviolent video, while controlling for violent media consumption …

The Influence Of Religious And Political Discrepancies On Parent-Adolescent Social Cohesion, Emily De Schweinitz Taylor

Theses and Dissertations

American youth are leaving organized religion at historical levels. Given that religious and political similarity (consensual solidarity) tends to strengthen affectual solidarity (emotional connection) in parent-adolescent dyads, decreasing adolescent religiousness and increasing political disagreements may threaten family social cohesion. However, during adolescence, youth empathy skills tend to increase and adolescents’ conflict with their parents tends to eventually subside. Based on principles outlined in intergenerational family solidarity theory, I hypothesized that adolescent empathy skills and authoritative parenting style would buffer the negative relational effects of religious and political discrepancies within the parent-adolescent relationship. I used Waves 2-4 (referred to as Times …

One important predictor of academic success and retention at the secondary level is student sense of school belonging. This thesis explores NHPI college students' perceptions of how their university instructors foster or undermine their sense of school belonging. A snowball sample of 97 NHPI students participated in 18 focus groups that included students from various islands and ethnicities in Oceania who were attending one U.S. university in the Pacific Rim. Focus group data were transcribed …

A Phenomenological Study Of Lived Experiences Of Muslim Women In Leadership At Institutions Of Higher Learning, Nora Bouzihay

Theses and Dissertations

Institutions of higher education (IHE) are increasingly prioritizing diversity, necessitating the recruitment of more faculty and staff leaders from marginalized populations to better support the university and underrepresented minority student groups. However, Muslim women leaders, as a religious minority group, have been largely overlooked in higher education minority research. This qualitative phenomenological study delves into the lived experiences of Muslim women leaders in North American IHE. Despite numerous legislative policies aimed at combating gender inequity in the United States, minority women in IHE leadership positions continue to face disparities. This study works to understand lived experiences through culturally responsive leadership …

Spatiotemporal Variation In Regeneration And Herbivory In Stable And Seral Aspen Stands, Sterling Burgess Kerr

Theses and Dissertations

Aspen forests are strongly influenced by disturbances like fire and ungulate herbivory, which can impact plant community composition and succession. Human activities alter these disturbances, affecting their timing, extent, and severity. Chapter 1 explores the effects of large-scale prescribed fire and mechanical thinning treatments on aspen regeneration and vulnerability to ungulate herbivory. Results show that while aspen regeneration was hindered by chronic ungulate herbivory in untreated areas, mechanical thinning and prescribed fire stimulated aspen regeneration. However, mechanically thinned plots were vulnerable to ungulate herbivory, with only prescribed fire having reduced browsing. Chapter 2 investigates herbivory patterns and recruitment across stable …

Methods For Finding Best Coset Codes For Physical-Layer Security, Andrew Glenn Swain

Theses and Dissertations

Finding best coset codes for secrecy over the binary erasure wiretap channel remains a difficult problem. Greater understanding of the structure of coset codes is necessary to reduce the problem space in which we search for these best codes. This dissertation presents new necessary conditions for a code to be best, including a condition that states that a code must maximize the minimum distance of both itself and its dual. It introduces and evaluates the accuracy of new heuristics to approximate the code's equivocation based on a code's weight enumerator polynomial. We also present a new tool for visualizing the …

Predicted Strength And Ductility Of Roof Truss Diaphragms With Tension-Only Rod Bracing And Hillside Washer Rod Connections, Emma Jean Brown

Metal buildings with roof truss diaphragms and tension-only rod bracing are a common structural system for single story industrial and commercial buildings. Despite the widespread use of metal building diaphragms in modern construction, there is limited knowledge on their strength and ductility under seismic loads. In this study, finite element models of diaphragm subassemblies and a full-size diaphragm were created to determine the strength and ductility of metal building diaphragms with tension-only rod bracing using hillside washer rod connections. Finite element models of two-tier diaphragm specimens that had been previously tested in the laboratory were created. Girders and purlins were …

Associations Between Young Children's Problematic Media Use And Physiological Regulation -- Does Temperament Act As A Mediator?, Noah Alexander Chojnacki

Theses and Dissertations

Given the ubiquity of media use, especially among young children, the current study examines the impact of problematic media use (PMU) on children's (N = 418, M age = 53.62 months, SD = 3.38 months, M and SD are taken from the full sample of 418 children) physiological functioning. With previous studies reporting relations between media use, temperament, and physiological regulation, it was hypothesized that children with greater levels of PMU would have lower levels of baseline respiratory sinus arrhythmia (RSA; a measure of physiological regulatory capacity). It is further hypothesized that, higher levels of negative affect, and lower levels …

Association Between Handgrip Strength And Muscle Mass In Children 6 To 10 Years Old, Samantha Velázquez Villalobos

Theses and Dissertations

Measuring body composition in children is important due to the rise of childhood obesity and changes that occur during pre-pubertal years. Sarcopenia, defined as a muscle mass loss and function, is increasingly recognized in pediatric populations, particularly in childhood obesity. Therefore, it is necessary to have measurements which not only provide an overall picture of body composition, but that can distinguish between muscle and fat mass. Methods of body composition such as Dual Energy X-ray Absorptiometry (DEXA) provide accurate assessments of body composition, but they are resource-intensive and impractical for routine monitoring in clinical or community settings. To address this, …

Exploring Mesolimbic Circuitry Modulation By Opiates, Interleukin-10, And Psychostimulants, Joakim W. Ronström

Theses and Dissertations

The mesolimbic dopamine (DA) system originates in the ventral tegmental area (VTA) and projects to the nucleus accumbens (NAc) and other areas including the basolateral amygdala (BLA), prefrontal cortex, and the hippocampus. Drug use induces reward and leads to dysregulation in these brain areas and eventually to substance use disorders (SUDs). Chapter 1 introduces the mesolimbic DA system and its relationship to drug use and their relevance to each chapter. Chapter 2 explores opioid effects on BLA circuitry which is known to play a role in the emotional response including anxiety and stress in SUDs. We showed that morphine induced …
