The Political Philosophy of Rabelais’s Pantagruel: Reconciling Thought and Action

Description: Political thinkers of the Renaissance, foremost among them Niccolò Machiavelli and Desiderius Erasmus, authored works commonly referred to as “mirrors of princes.” These writings described how princes should rule, and also often recommended a certain arrangement or relationship between the intellectual class and the political powers. François Rabelais’s five books of Pantagruel also depict and recommend a new relationship between these elements of society. For Rabelais, the tenets of a philosop… more

Lines by Someone Else: the Pragmatics of Apprompted Poems

Description: Over the last sixty years, overtly intertextual poems with titles such as “Poem Beginning with a Line by John Ashbery” and “Poem Ending with a Line by George W. Bush” have been appearing at an increasing rate in magazines and collections. These poems wed themselves to other texts and authors in distinct ways, inviting readers to engage with poems which are, themselves, in conversation with lines from elsewhere. These poems, which I refer to as “apprompted” poems, explicitly challenge readers to… more

First Principles Study of Metastable Beta Titanium Alloys

Description: The high temperature BCC phase (b) of titanium undergoes a martensitic transformation to HCP phase (a) upon cooling, but can be stabilized at room temperature by alloying with BCC transition metals such as Mo. There exists a metastable composition range within which the alloyed b phase separates into a + b upon equilibrium cooling but not when rapidly quenched. Compositional partitioning of the stabilizing element in as-quenched b microstructure creates nanoscale precipitates of a new simple he… more

Contributions to Descriptive Set Theory

Description: In this dissertation we study closure properties of pointclasses, scales on sets of reals and the models L[T2n], which are very natural canonical inner models of ZFC. We first characterize projective-like hierarchies by their associated ordinals. This solves a conjecture of Steel and a conjecture of Kechris, Solovay, and Steel. The solution to the first conjecture allows us in particular to reprove a strong partition property result on the ordinal of a Steel pointclass and derive a new boundedn… more

Was There a Trumpet Sonata Before the Trumpet Sonata? an Investigation of Girolamo Fantini’s Trumpet Sonatas with Respect to Other Stile Moderno Solo Instrumental Sonatas

Description: In 1638 Girolamo Fantini wrote eight multi-sectional trumpet sonatas. This dissertation compares these sonatas with recognized stile moderno solo instrumental sonatas by Biagio Marini and Dario Castello in order to show that Fantini’s sonatas are stile moderno trumpet sonatas. This study looks at how form, texture, motivic organization, and instrumental effects function in the works of Castello, Marini, and Fantini. This comparison shows how and to what degree Fantini uses stile moderno chara… more

Racial Microaggressions: Relationship to Cardiovascular Reactivity and Affect Among Hispanic/Latinos and Non-Hispanic Whites

Description: Racial microaggressions are a type of perceived discrimination entailing a brief pejorative message by a perpetrator, whether verbal or nonverbal, intentional or unintentional, about a target person that operates below the level of conscious awareness. Research supports a relationship between perceived discrimination and worse mental and physical health outcomes, with the literature centered mainly on non-Hispanic blacks. Less research exists on how perceived discrimination, specifically raci… more

Foreignizing Mahler: Uri Caine’s Mahler Project As Intertraditional Musical Translation

Description: The customary way to create jazz arrangements of the Western classical canon—informally called swingin’-the-classics—adapts the original composition to jazz conventions. Uri Caine (b.1956) has devised an alternative approach, most notably in his work with compositions by Gustav Mahler. He refracts Mahler’s compositions through an eclectic array of musical performance styles while also eschewing the use of traditional jazz structures in favor of stricter adherence to formal ideas in the original… more
