Refining The Geochronologic Framework Of The Early Cretaceous Nonmarine Western Interior Basin, Usa, Jack Fekete
Refining The Geochronologic Framework Of The Early Cretaceous Nonmarine Western Interior Basin, Usa, Jack Fekete
Graduate Theses and Dissertations
The Early to mid-Cretaceous marks a period of dynamic shifts in tectonism, depositional environments, climate, and biota across the mid-North American continent. However, despite their importance for understanding crucial biotic and geologic transitions during this period, nonmarine Early Cretaceous strata of the Western Interior Basin (WIB) remain poorly constrained geochronologically. Radiometric dating of syndepositional detrital minerals, such as ash-fall zircon, offers a solution to refining geochronologic frameworks. However, a magmatic lull in the Cordilleran magmatic arc during the Early Cretaceous limited the delivery of syndepositional zircon to the WIB, impeding such refinement. In this dissertation, I developed and tested new …

Co-Creating Play:Utilizing Comics To Potentialize Participatory Self-Determination In Marginilized Young Adults, Marlin Mcknight
Graduate Theses and Dissertations
Storytelling has long served as a vital mechanism for preserving cultural heritage, transmitting values, and fostering intergenerational connection (Moeshlin, 2024). Despite this significance, graphic narratives such as comics and graphic novels have been historically marginalized—dismissed as trivial “children’s media” or reduced to entertainment rather than recognized as culturally resonant tools (McCloud, 1993). This marginalization intensified as comics evolved to depict adult themes and, at times, harmful stereotypes, triggering social backlash that stigmatized their utility for younger audiences (Segran, 2020). Consequently, scholarly exploration of comics’ therapeutic potential has stagnated, hindered by the medium’s tumultuous history. This study bridges this gap by …
