The Power Of Presidential Rhetoric: The State Of The Union And Legislative Productivity, Kaylar M. Recker

Graduate Research Theses & Dissertations

Congressional scholars have long debated what factors influence legislative productivity. Mayhew argues that “landmark enactments” are more likely to occur under divided-party control of government, while Binder takes exception to this contention by incorporating legislative demand and different types of divided-party governments. Dodd and Schraufnagel argue that topical legislative productivity is the best measure of legislative competence and quasi-divided government is especially counterproductive, when accounting for polarization. This research incorporates all of these factors: divided government, legislative demand, and polarization; however, my interest is more about the imperial presidency thesis, which argues that presidents have become too powerful relative to …

The Monster As Queer Opportunity: Monstrous (Re)Construction, Embodiment, And Approbation On The Boulet Brothers' Dragula, Adam Harrison Reedy

Graduate Research Theses & Dissertations

While mainstream tides in the drag industry have largely come to signify the art form’s growing popularity, there exist multiple alternative artists and communities who have yet to find space for their expressions to thrive and find praise. The Boulet Brother’s Dragula is constructed out of such need, giving a space to alternative, radical, or “monster” drag artists who have experienced the pains of ridicule, alienation, and alterity in both queer and heteronormative spaces. Prior research on drag artistries has often glossed over alternative drag artistries, comparing them to popular or heteronormative representations while also focusing disproportionately on gender presentation. …
