The Role Of Executive Functioning On Anxiety And Overcontrol On Neurodiverse Youth, Sydney Przygoda

Theses, Dissertations and Culminating Projects

Autistic youth are at an elevated risk of developing anxiety. Overcontrol, or excessive self-control, shares similar clinical challenges (i.e. rigidity, social perfection) that are often associated with anxiety. Executive functioning (EF) is well-established as being positively associated with anxiety. Taking all this into account, it was predicted that EF may serve as a moderator to the relationship between overcontrol and anxiety. Using both parent and child responses to the Overcontrol in Youth Checklist, Multidimensional Anxiety Scale for Children and Behavior Rating Inventory of Executive Function-2, this current study explored how overcontrol and anxiety are related. Further, it tested the role …

Spatiotemporal Patterns In Diadema Antillarum Settlement In The Florida Keys: Implications For Habitat Restoration, Julia Skowronski

Theses, Dissertations and Culminating Projects

The long-spined sea urchin (Diadema antillarum) is a keystone herbivore in the Caribbean and western Atlantic Ocean. It is found in various marine habitats including coral reefs and seagrass beds. On coral reefs, D. antillarum is part of a grazer assemblage that consumes fast-growing macroalgae and reduces competition with reef-building corals. In 1983–84 and again in 2022, D. antillarum experienced mass mortality, and presently populations have not recovered to their pre-1983 levels. Slow population growth is likely due to limited recruitment success under high post-settlement morality caused by a lack of suitable habitat. Here, patterns in larval settlement were examined …

Betrayal As A Moderator Of Covid-19 Exposure And Ptsd Symptoms, Karly Sara Weinreb

Theses, Dissertations and Culminating Projects

In response to the COVID-19 pandemic, there has been interest in understanding how individuals have fared regarding their mental health symptoms, such as symptoms of PTSD. Prior studies have established a link between COVID-19 and PTSD without considering how COVID-19 may relate to the four PTSD symptom clusters. Further, those who feel betrayed by either an individual or institution tend to have more severe PTSD (Martin et al., 2013). It is possible that individuals felt a level of both interpersonal and institutional betrayal towards other individuals or institutions for exposing them to environments in which there was a risk of …

Vulnerability Of Semantic Networks In Multiple Sclerosis: An Analysis Of Verbal Fluency Data, Sophia Lall

Theses, Dissertations and Culminating Projects

Word finding difficulty is a frequently reported subjective cognitive concern among persons with Multiple Sclerosis (pwMS). Word-finding relies on several information retrieval processes, including search and retrieval from the conceptual store, the phonological store, the syllabary, as well as other stores of information. Neuropsychological assessments, including the semantic verbal fluency measure, can be used to measure word retrieval abilities. Despite this, the MS research literature shows that neuropsychological assessment of semantic verbal fluency yields mixed results in detecting word-finding difficulties. While some studies report finding statistically lower semantic fluency scores in pwMS relative to healthy controls (HC), others found no …

Camus In A Post-Covid World: A Bibliotherapeutic Approach To Coping With Crisis, Jessica Titterington

Theses, Dissertations and Culminating Projects

This thesis examines the usage of absurdist literature, particularly a selection of works by Albert Camus, and their relevance to bibliotherapy. The three selected works are his novels The Plague and The Stranger, as well as his essay The Myth of Sisyphus. By analyzing these works through a psychoanalytic lens and with the consideration of generational theory, utilizing absurdist literature as an alternative “medicine” in times of crisis, especially in instances where immediate medical aid is not available, is shown to be beneficial. This thesis also uses the recent COVID-19 pandemic as a model for global crises and explores the …

Analysis Of Social Behavior Of The African Great Apes During Feeding And Non-Feeding Contexts, Jessica Hale

Master's Theses

The three African great apes, bonobos, chimpanzees and gorillas, despite similar habitats, differ considerably in their sociality and feeding ecology. There have been many studies that have investigated the feeding ecology and social behaviors of these species, but there is extremely limited literature available on how feeding ecology may have affected ape social evolution. Chimpanzees are frugivorous, which forces them into close proximity when foraging given the clumped nature of this resource. Bonobos and gorillas, however, are fallback food consumers, which allow them to spread out as they forage. This thesis project aims to test the hypothesis that differences in …

Educating Srnas On Barriers And Facilitators Of Clinical Learning, Mesud Dedic, Richard Heuermann

Doctor of Nursing Practice Projects

A national survey of 143 Student Registered Nurse Anesthetists (SRNAs) conducted by Clancy and Bruinius (2022) revealed that factors impeding effective SRNA clinical education include unstable preceptorship, hostile environments, limited autonomy, and heavy didactic burdens. Clancy and Bruinius (2022) also found that facilitators of SRNA clinical education include rapport with preceptors, effective feedback, strong clinical site orientation, and beginning of day discussions. This project aimed to enhance second-year SRNAs' clinical success by mitigating these evidence-based barriers and employing these evidence-based facilitators by developing a presentation for SRNAs and assessing its effectiveness through a pre-implementation survey and post-implementation survey. The literature …

Generalizations Of The Hardy Spaces And The Schwarz Boundary Value Problem, William L. Blair

Graduate Theses and Dissertations

We prove that many of the boundary properties associated with functions in the classic holomorphic Hardy spaces on the complex unit disk are present in Hardy classes of solutions to certain nonhomogeneous Cauchy-Riemann equations and higher-order generalizations of these equations. Also, we explicitly solve generalizations of the Schwarz boundary value problem on the complex unit disk and the upper-half plane when the boundary condition is in terms of boundary values in the sense of distributions.
