Transcription of Baroque Works for Classical Guitar: J S Bach's Sonata in D Minor (Bwv 964) As Model

Description: Continuing the common practice of composers of the Baroque period to transcribe their own or other composers' works for a different instrument, this dissertation contributes to studies of J. S. Bach's repertory as the source of program material for the classical guitar. It is from differences revealed through a comparative analysis of Bach's Violin Sonata No. 2 (BWV 1003) and his harpsichord arrangement thereof – Sonata in D minor (BWV 964) – that principles of transcription are derived and or… more

Traveling Wave Solutions of the Porous Medium Equation

Description: We prove the existence of a one-parameter family of solutions of the porous medium equation, a nonlinear heat equation. In our work, with space dimension 3, the interface is a half line whose end point advances at constant speed. We prove, by using maximum principle, that the solutions are stable under a suitable class of perturbations. We discuss the relevance of our solutions, when restricted to two dimensions, to gravity driven flows of thin films. Here we extend the results of J. Iaia and S… more

Warrior Women in Early Modern Literature

Description: Fantasies about warrior women circulated in many forms of writing in early modern England: travel narratives such as Sir Walter Ralegh's The Discoverie of Guiana (1595) portray Amazon encounters in the New World; poems like Edmund Spenser's The Faerie Queene (1596) depict women's skill with a spear; and the plays of Shakespeare, John Fletcher, and others stage the adventurous feats of women on the battlefield. In this dissertation, I analyze the social anxieties that emerge when warrior women t… more

The Ways of Reflection: Heidegger, Science, Reflection, and Critical Interdisciplinarity

Description: This thesis argues that there is a philosophical attempt directed at combating the fragmentation of the sciences that starts with Heidegger and continues today through Trish Glazebrook's interpretations of the former's concept of "reflection," and Carl Mitcham and Robert Frodeman's concept of "critical interdisciplinarity" (CID). This is important as the sciences are both more implicated in our lives and more fragmented than ever. While scientific knowledge is pursued for its own sake, the pe… more

Zinc Oxide Nanoparticles for Nonlinear Bioimaging, Cell Detection and Selective Cell Destruction

Description: Light matter interactions have led to a great part of our current understanding of the universe. When light interacts with matter it affects the properties of both the light and the matter. Visible light, being in the region that the human eye can "see," was one of the first natural phenomenon we used to learn about our universe. The application of fundamental physics research has spilled over into other fields that were traditionally separated from physics, being considered two different scien… more

Ab Initio and Density Functional Investigation of the Conformer Manifold of Melatonin and a Proposal for a Simple Dft-based Diagnostic for Nondynamical Correlation

Description: In this work we address two problems in computational chemistry relevant to biomolecular modeling. In the first project, we consider the conformer space of melatonin as a a representative example of “real-life” flexible biomolecules. Geometries for all 52 unique conformers are optimized using spin-component scaled MP2, and then relative energies are obtained at the CCSD (T) level near the complete basis set limit. These are then used to validate a variety of DFT methods with and without empiric… more

Ability of Offenders with Psychopathic Traits to Simulate Cognitive and Affective Empathy

Description: The accurate assessment of psychopathy constitutes a critical component of forensic assessments addressing offender populations. Among the core characteristics of psychopathy, the interpersonal component of deception and empathic deficits are prominently observed in offenders with psychopathic traits. Given the negative consequences of being classified as a psychopath, offenders may be likely to minimize their psychopathic traits. In particular, no research has investigated whether offenders… more

Accessing the Power of Aesthetics in Human-computer Interaction

Description: In information systems design there are two schools of thought about what factors are necessary to create a successful information system. The first, conventional view holds that system performance is a key, so that efficiency characteristics such as system usability and task completion time are primary concerns of system designers. The second, emerging view holds that the visual design is also the key, so that visual interface characteristics such as visual appeal, in addition to efficiency ch… more

Accuracy and Interpretability Testing of Text Mining Methods

Description: Extracting meaningful information from large collections of text data is problematic because of the sheer size of the database. However, automated analytic methods capable of processing such data have emerged. These methods, collectively called text mining first began to appear in 1988. A number of additional text mining methods quickly developed in independent research silos with each based on unique mathematical algorithms. How good each of these methods are at analyzing text is unclear. … more

Alchemies

Description: This thesis consists of a collection of poems and a critical preface. The preface is a discussion of Elizabeth Bishop's descriptive mode, as demonstrated by three of her poems: "Sandpiper," "The Monument," and "Santarém." I argue for Bishop's descriptions as creative acts, and examine the gestures that help her make the reader aware of the shaping power she exercises.
