Power Play: The President\u27s Role in Shaping Renewable Energy Regulation and Policy
Full text linkWith the impacts of climate change becoming more and more apparent every day, finding means of effective action to mitigate its effects become increasingly critical. While localized work can play an important role, federal action is necessary to have the most widespread and effective impact, especially on interconnected issues such as clean energy. Congressional action is the avenue of change at this level, however in an increasingly partisan and divided environment, progress on this front is far short of what is needed.
Looking to the president is logical here, both as a single actor more insulated from partisan fights, but also as head of the branch in charge of implementing the nation’s laws. This paper looks to explore what means of influence the president has on the action taken by federal agencies and how such methods can be made more effective. Through a principal-agent framework, the role of regulatory and appointment powers are examined with a variety of historical and contemporary case studies. While only a subset of the powers afforded to a president, the areas explored offer wide latitude for action, in areas that are particularly important for energy development. The paper concludes with some reflections for the future, suggesting how these considerations can be practically applied
\u3ci\u3eOnkel Toms Hütte\u3c/i\u3e: Translation, Intervention, and Nation
No full textUncle Tom’s Cabin is one of the most influential novels in American history and has a complicated series of meanings in America from its publication to present. The novel became an international bestseller in its time—outsold only by the bible. Onkel Tom’s Hütte, the German version, became nearly as popular in Germany as in America. This project studies the (mis)translation of the novel in German culture and how the choices made in its adaptations, appropriations, and truncations mirror German historical attitudes towards Blackness, abolition, and American democracy. The German versions of Onkel Toms Hütte in the late 1850s-1900 decontextualized through removal of the novel from its intended audience and political context, politicized, and commodified the novel through interventions of translation and translators. The German versions removed the novel more from its source than just the journey across an ocean and a language barrier suggests. Through the multifaceted nature of German practices, along with the workings of copyright laws, an erstwhile religious, sentimental American text became a trade object that sought to intervene in, or at the very least, reflect the German nation building process
Modeling Oyster Growth Dynamics in FLUPSY Systems to Develop a Decision Support Tool for Seed Management
No full textAs the Gulf of Maine warms and lobsters move north to colder waters, Maine’s working water front has begun to diversify. There is a thriving new ecosystem of aquaculturists looking to keep Maine’s waterfront traditions alive in a lasting, sustainable way. One of the most popular aquaculture industries is oyster farming. With an increasing number of oyster farms developing in Midcoast Maine each year, we seek to develop a decision support tool to aid farmers in seed management. Oyster farmers can choose weather or not to use an upweller on their farm, and our goal is to provide guidance on this choice, as well as on upweller management. We begin by culminating and synthesizing data from previous literature and oyster farmers. We then use this data to first build a basic analytical model of a cohort of oysters based on an exponential growth model. We expand this model to include biological differences among oysters as well as management practices. Finally, we walk through a case study, illustrating how our tool could be used to make seed management decisions on an individual farm scale

The Current Support Theorem in Context
Full text linkThis work builds up the theory surrounding a recent result of Erlandsson, Leininger, and Sadanand: the Current Support Theorem. This theorem states precisely when a hyperbolic cone metric on a surface is determined by the support of its Liouville current. To provide background for this theorem, we will cover hyperbolic geometry and hyperbolic surfaces more generally, cone surfaces, covering spaces of surfaces, the notion of an orbifold, and geodesic currents. A corollary to this theorem found in the original paper is discussed which asserts that a surface with more than cone points must be rigid. We extend this result to the case that there are more than cone points. An infinite family of cone surfaces which are not rigid and which have precisely cone points is also provided, hence demonstrating tightness
Religious Negotiation and Identity Formation: Reading Material Religion in Oaxaca’s “Guelaguetza Oficial”
Full text linkThe Oaxacan Guelaguetza Oficial is a folk-dance festival in the state of Oaxaca, Mexico which takes place on the last two Mondays of July each year. This state-sponsored celebration of Oaxacan identity is intertwined within histories of Indigenous religious belief and Catholic everyday practice. The Guelaguetza Oficial can be traced back to late 19thcentury celebrations venerating the Virgen del Carmen Alto. Oaxaqueños today predominantly practice an Indigenous-Catholic tradition whose rituals, festive scripts, pantheon of popular saints, and immanent understandings of heavenly power over earthly events can be traced back to negotiations between Indigenous forms of popular belief and institutionalized Catholic practice. Through historical and present-day religious tensions between existing modes of Indigenous religious belief and institutionalized Oaxacan Catholic practice, this thesis asserts that while Indigeneity often represented an obstacle to different structures of power in Mexican history, hegemonic institutions eventually came to accept the lasting presence of Indigenous identity and religious life to varying degrees within Mexican society and culture. This resulting reading of Guelaguetza demonstrates how religion is fundamentally implicated in the history of public festival and popular culture in Oaxaca. Furthermore, this thesis argues that Indigenous-Catholicism has not lost its prominence in public space in Oaxaca despite the reforms of post-1910 Oaxacan state and Mexican national politics and the effects of globalized neoliberal economies in the late 20th and early 21st centuries
Properties of Slicing Conditions for Charged Black Holes
Full text linkWe consider an earlier analysis by Baumgarte and de Oliveira (2022) of static Bona-Massó slices of stationary, nonrotating, uncharged black holes, represented by Schwarzschild spacetimes, and generalize that approach to Reissner-Nordström (RN) spacetimes, representing stationary, nonrotating black holes that carry a nonzero charge. This charge is parametrized by the charge-to-mass ratio λ ≡ Q/M, where M is the black-hole mass and the charge Q may represent electrical charge or act as a placeholder for extensions of general relativity. We use a height-function approach to construct time-independent, spherically symmetric slices that satisfy a so-called Bona-Massó slicing condition. We compute quantities such as critical points and profiles of geometric quantities for several different versions of the Bona-Massó slicing condition. In some cases we do this analytically, while in others we use numerical root-finding to solve quartic equations. We conclude that in the extremal limit as λ → 1, all slices that we consider approach a unique slice that is independent of the chosen Bona-Massó condition.
We then study dynamical, i.e. time-dependent, Bona-Massó slices by analytically predicting the qualitative behavior of the central lapse, i.e. the lapse at the black-hole puncture, for a particular slice that Alcubierre (1997) proposed to mitigate gauge shocks. These shock-avoiding slices are a viable alternative to the very common so-called 1 + log slices but exhibit different behavior in dynamical simulations. We use a perturbation of the radial coordinate at the location of the puncture to recover approximately harmonic late-time oscillations of the central lapse that Baumgarte and Hilditch (2022) observed in numerical simulations
Vienna Secession
Full text link‘Vienna Secession’ is a poetry manuscript broken into four distinct sections: “The Vienna Secession,” “Waltzes,” “Short Talks,” and “Other.” Most of the manuscript is in dialogue with Secessionist artists, or the ethos of the Vienna Secession. However, others, like the haikus, are exercises of form and responses to other contemporary poets, such as Robert Hass or Richard Wright. The manuscript explores different genres, including ekphrasis, prose, and experimental poems, like the ‘Waltzes,’ which employ 3/4 meter to emulate the Viennese waltz.
The heart of the project is its sonic awareness—pulling from W.H. Auden, August Kleinzahler, and other musically-oriented poets. Outside the ‘Short Talks’ section, the poems’ sonic and phonetic qualities are integral to their style and meaning. At times this may be subtle, or even indiscernible, but overall, careful attention is paid to the sound and rhythm of the poems. The manuscript should be considered in both musical and literary terms.
Rainer Maria Rilke’s ‘Duino Elegies’ and advice in ‘Letters to a Young Poet’ are instrumental in creating these poems. As a ‘first statement,’ many poems battle with the insecurities of a young poet and exemplify the grapple of an aspiring creative. The poems consider antiquated things through contemporary frameworks; relationships, communication, masculinity, and suffering, to name a few. A general incentive of the work is to provide fresh perspectives on historical art and to import its most apposite sentiments into our current moment
