The Influence Of Foster Parent Characteristics On The Relational Permanence Of Foster Youth, Yogita Venkata

Honors Undergraduate Theses

Research suggests that lack of permanency is associated with an increased risk of aggression, mental instability, and delinquent behavior in children (Leve et al., 2012). A crucial component of permanency involves establishing stable connections, including relational permanence with peers and adults, which are believed to enhance the well-being of foster youth (Wekerle et al., 2009). Further, the literature suggests a relationship between a parent’s adverse traumatic experiences, their attachments to their own parents, and their ability to regulate their foster child’s relational permanence to supportive adults and peers. Foster parents who have experienced trauma are often insecurely attached to their …

Spatial Distribution And Significance Of Burdens To Environmental Justice In Parramore, Florida: An Urban Resilience Perspective, Lex Tracton

Honors Undergraduate Theses

In response to climate change, economic instability, and rapid urbanization, the notion of urban resilience has gained prominence in city planning and governance. Urban resilience is the ability of a system to adapt to new baseline conditions developing as a result of disturbances. This study is focused on one of urban resilience’s sub-tenets, ecological resilience. Ecological resilience is the ability of a system to sustain ecosystem services following a disturbance (i.e. droughts, flooding, heat waves). The health of the environment prior to a disturbance informs post-disturbance ecological resilience. An already stressed and unbalanced system, or an ecosystem with degraded health, …

Madness As Epistemic Advantage: The Relevance Of Standpoint Epistemology To The Evolution Of Mental Health Care, Aven E. Kazmier

Honors Undergraduate Theses

The intent of this thesis is to examine the potential epistemic advantage possessed by those with lived experience of mental illness. The frequent lack of conceptual alignment between the perspectives of individuals with lived experience and the biomedical model of mental illness has often resulted in epistemic injustice—lived experiential knowledge tends to be devalued and excluded from larger discussions about mental health. I propose that by occupying a marginalized social location and critically engaging with one’s social position, psychopathologized individuals may achieve a standpoint that allows a deeper comprehension of the systems of power that affect the mental health care …

The Influence Of Genes On The Migratory Timing Of Great Reed Warblers, Emily Fackler

Honors Undergraduate Theses

Many organisms migrate; however, there is a lack of knowledge on the mechanisms that drive migration timing, including which genes play a role. The great reed warbler (Acrocephalus arundinaceus), a migratory bird that breeds in Eurasia and overwinters in sub-Saharan Africa, is an excellent model to study the genetics of migration. Each season, some individuals migrate early, whereas others migrate later in the season. In other words, they exhibit differences in their migratory chronotypes. Past research has identified three candidate genes (TOP1, PEAK1, and CPNE4) that influence the migratory chronotypes of another avian species, …

Metaontological Dismissive Strategies: Implications And Applications In Metaphysics Of Race And Gender, Ethan F. Stumpp

Honors Undergraduate Theses

Metaontological discourse, inquiring into the nature, methodology, and aims of ontology, has functioned as the war ground for those skeptical of ontological projects against those who believe that ontological inquiry is substantive (i.e., meaningful, important, worth pursuing). I call the inquiry which engages in determining criteria to distinguish substantive from nonsubstantive inquiry/discourse: “the metaphysics of discourse”. In this project, I identify three frameworks in the metaphysics of discourse: Easy Ontology, The “Merely Verbal” Framework, and Metaphysical Structuralism. My primary concern is to show that these discourse frameworks or dismissive strategies all fail to provide sufficient criteria to properly delineate substantive …

Adaptation Of A Commercially Available Galvanic Skin Response Sensor To Measure Respiration Across The Chest For Heart Rate Variability Monitoring, Breno C. Dobal

Honors Undergraduate Theses

Heart rate variability (HRV) is a naturally occurring cardiovascular phenomenon referring to the changing timing between consecutive heartbeats. The connection between HRV and overall cardiovascular health and autonomic nervous system function has been well established through prior research and well documented in existing literature. The existing studies, however, included shorter HRV subject recording session, using traditional HRV monitoring methods that do not typically combine electrocardiogram (ECG), seismocardiogram (SCG) and galvanic skin response (GSR) respiration monitoring. The inclusion of longer HRV subject recording may allow for further insight on the possible effects of given observable biological phenomenon on HRV.
