Iron Isotope Transformations In Saanich Inlet, Claire Onak

USF Tampa Graduate Theses and Dissertations

Iron (Fe) is required for many biogeochemical processes, with Fe bioavailability and chemistry being controlled by redox reactions that transform Fe between oxidation states and dissolved and particulate phases. In oxic seawater, Fe is present in the Fe(III) oxidation state, mainly as Fe oxyhydroxides. Under anoxic marine conditions, such as margin sediments under oxygen minimum zones or restricted basins with anoxic bottom water, Fe(III) is reduced to Fe(II), which is highly soluble and can be present at high concentrations ([Fe]). Fe isotope ratios (δ56Fe relative to IRMM-14) can be used to characterize Fe redox transformations, constrain Fe sources of Fe …

Effectiveness Of Contact-Based Strategies On Improving Mental Illness Stigma And Help-Seeking Behaviors Within Families, B. Michelle Wilks

USF Tampa Graduate Theses and Dissertations

Adolescence is a developmental period that often involves extreme physical, psychological, and emotional changes and sometimes the experience of significant personal and social challenges. In addition to these challenges, youth are trying to find their place in the world and developing their identities, which depend heavily on their relationships with others. Adolescents who struggle with their mental health and also fail to develop meaningful connections with others, tend to have poor self-esteem, self-isolate, are ostracized by others, and have a poor social self-concept, all of which are associated with poor mental health and increased risk for suicidal ideation.

An Ecofeminist Ontological Turn: Preparing The Field For A New Ecofeminist Project, M. Laurel-Leigh Meierdiercks

USF Tampa Graduate Theses and Dissertations

Ecofeminists have predominantly refuted oppressive conceptual frameworks by rejecting dualistic logic and value hierarchies, despite the foundational view of ontology that underlies our logic and value systems. I argue that ecofeminists must engage in the creative process of articulating an ecofeminist ontology. I demonstrate that the omission of ontological discourse in ecofeminist scholarships is primarily due to the time period during which ecofeminism gained peak traction and their concerns with essentialism. I also show that feminists experienced an ontological turn in the 2000s that produced a new model for ontological theories that would be beneficial for ecofeminists to embrace. In …

Making The Invisible Visible: (Re)Envisioning The Black Body In Contemporary Adaptations Of Nineteenth-Century Fiction, Urshela Wiggins Mckinney

USF Tampa Graduate Theses and Dissertations

A trend in neo-Victorian adaptations -- both novels and films-- that reimage, and at times reinterpret, canonical Victorian texts is the inclusion of nonwhite, mainly Black, perspectives, which has gained considerable traction in recent years. A vital aspect of this trend is the purposeful attempt to re-establish iconic Victorian characters through Black characterizations. In doing so, filmmakers and authors are reinvigorating familiar texts to provide an inclusionary space for the Black experience previously ignored in the original texts. These adaptations, which revisit and often reinterpret Victorian fiction, have undergone notable transformations by incorporating Black characters to fill voids in traditional …

“Manne, For Thy Loue Wolde I Not Lette”: Eucharistic Portrayals Of Caritas In Medieval And Early Modern English Literature And Drama 1350-1650, Rachel Tanski

USF Tampa Graduate Theses and Dissertations

The religious Reformation in England heralded significant changes in Christian theology, clerical and lay practices, and textual interpretation. These sweeping changes encompassed nearly all avenues of intellectual thought, and debates ranged from whether or not religious texts should be written in the traditional latin or the vernacular, thereby determining whether interpretive authority remained within the clergy or became available to laypersons, to arguments over very specific aspects of theological doctrine, such as the substantive nature of the Eucharist. These debates were not confined among Church officials; politicians, monarchs, commoners, and literary authors engaged in these discussions and had been doing …

The Rust Belt Gothic: Charting The Affective Politics Of Deindustrialization And The Emergence Of A Great Lakes Horror Genre In Film, Micheal B. Raines

USF Tampa Graduate Theses and Dissertations

Within the past decade, a string of notable horror films set within the Steel Belt has emerged. These works collectively invoke the specter of the ‘Rust Belt’ in their narratives: the industrial Midwest’s derelict urban and suburban sprawls in the wake of the economic decline and white flight of the USA’s once-mighty manufacturing sector. Scholarship has commented upon the subtext of these works individually but fails to observe their collective nature as an emergent subgenre in horror fiction, centered upon directly confronting the Steel Belt’s twentieth-century history of stagnation. In this paper, I examine films which share clear aesthetic and …

Count Me In: A Study Of Social Validity, Positive Behavioral Interventions And Supports, And A High School, Amie Dia Davis
