Music on the Edge of Silence

Description: This paper presents a discussion of functional silence in contemporary classical music with a particular focus on the music of Salvatore Sciarrino and Jürg Frey, two composers whose drastically-contrasting bodies of work both occupy the interstitial space between the audible and inaudible. To begin, I address three main questions: what are the functions of silence in a musical context, how do the characteristics of a work affect our perception of these silences, and how do these functions relat… more

Music as a Woven Narrative to an Absurd Tale in Act One of The Metamorphosis

Description: Act one of The Metamorphosis is based on the novella by Franza Kafka of the same title. In the writing of the act, George Benjamin's Into the Little Hill and Oliver Knussen's Where the Wild Things Are provide a model of using musical material as a storytelling device. Benjamin emphasizes the parallel nature of Crimp's text through the manipulation of similar music between the acts. Knussen uses form and color to emphasize Max's childlike energy and his desire to return home. In act one of The M… more

Information Content of Non-GAAP Earnings of Cross-Listed Companies

Description: To supplement earnings reported under generally accepted accounting principles (GAAP), public companies often voluntarily report alternative measures of earnings called non-GAAP earnings (NGE). These companies assert that NGE exclude the effect of non-recurring transactions, thereby helping users of financial information to better assess the company's past performance and prospects. Because NGE measures are not well defined, managers can exploit the inherent discretion in calculating NGE to mis… more

Rivers, Mountains, and Everything in Between: How Terrain Affects Interstate Territorial Disputes

Description: Geography has been a central element in shaping conflict through the ages, and is especially important in determining which states fight, why they fight, when they fight, and more importantly, where they fight. Despite this, conflict literature has primarily focused on human geography while largely ignoring the geospatial context of ‘where' conflict occurs, or crucially, doesn't occur. Territorial disputes are highly salient issues that quite often result in militarized disputes. Terrain has… more

Fence, Flavor, and Phantasm: Balancing Japanese Musical Elements and Western Influence within an Historical and Cultural Context

Description: Given the diversity found in today's Japanese culture and the size of the country's population, it is easy to see why the understanding of Japanese wind band repertoire must be multi-faceted. Alongside Western elements, many Japanese composers have intentionally sought to maintain their cultural identity through the addition of Japanese musical elements or concepts. These added elements provide a historical and cultural context from which to frame a composition or, in some cases, a composer's c… more

Computational Investigation of DNA Repair Enzymes: Determination and Characterization of Cancer Biomarkers and Structural Features

Description: Genomic integrity is important for living cells' correct functioning and propagation. Deoxyribonucleic acid as a molecule is a subject to chemical reactions with agents that can come from environment as well as from internal metabolism processes. These reactions can induce damage to DNA and thus compromise the genetic information, and result in disease and death of an organism. To mitigate the damage to DNA, cells have evolved to have multiple DNA repair pathways. Presented here is a computat… more

Non-Resonant Uniserial Representations of Vec(R)

Description: The non-resonant bounded uniserial representations of Vec(R) form a certain class of extensions composed of tensor density modules, all of whose subquotients are indecomposable. The problem of classifying the extensions with a given composition series is reduced via cohomological methods to computing the solution of a certain system of polynomial equations in several variables derived from the cup equations for the extension. Using this method, we classify all non-resonant bounded uniserial ext… more
