La Valse And The Parisian Salon: Nostalgic Continuities And Sonorous Modernisms, Claire Weydt

Graduate Theses, Dissertations, and Problem Reports (ETD)

Immediately following World War I and the death of prominent French composer Claude Debussy, French composers and music critics were concerned that the war created an unbridgeable chasm between generations of composers who, through their various aesthetic allegiances, worked to define musical sounds as undeniably French. Numerous scholars have characterized this process as an aesthetic rupture brought on by the World Wars. French composer Maurice Ravel (1875-1937), however, seems to have bridged this gap, at least for some influential critics. My project challenges notions of wartime rupture by resituating musical modernism within a framework of aesthetic continuity. Ravel’s choreographic poem …

Using Visual Prompts To Analyze Ejection Fraction In Echocardiograms, Kevin Reisch

Graduate Theses, Dissertations, and Problem Reports (ETD)

Left ventricular ejection fraction (LVEF) is a critical biomarker for heart failure, but manual estimation from echocardiograms is time-consuming. Artificial intelligence can be used to accelerate this process, allowing clinicians to focus on other critical tasks. Current methods typically train models from scratch on echocardiogram datasets; however, this approach is limited by the scarcity of large medical imaging datasets, which are expensive and difficult to acquire. We present a transfer learning approach that leverages pretrained models from massive datasets, enabling continuous improvement as foundation models advance. Our method employs visual prompting to generate trainable masks for echocardiogram videos, transforming the …

Rethinking Compliance: How Goal Congruence Can Lead To Noncompliance And Positive B2b Performance, Paige Harrison Fender

Graduate Theses, Dissertations, and Problem Reports (ETD)

Traditional marketing theories (e.g., agency theory) suggest that aligning goals with a partner firm will enhance compliance and lead to better overall performance for both firms. The research on positive deviance, in contrast, suggests that a firm may deviate from contractual terms in order to accomplish shared goals and enhance performance. Merging these perspectives and pulling from more nuanced discussions of compliance, this dissertation explores the potential deleterious effects of goal congruence on compliance. Specifically, we examine the conditions in which goal congruence leads to both compliance and noncompliance and how these conditions impact performance.

Reconnection-Driven Electron Acceleration, Ripudaman Singh Nirwan

Graduate Theses, Dissertations, and Problem Reports (ETD)

Magnetic reconnection converts the magnetic energy available in a plasma to the kinetic energy of its constituent particles. In the simplest case, it occurs between anti-parallel magnetic field lines meeting in a plane. Another variant known as ‘component reconnection’ involves field lines reconnecting at an angle, giving a non-zero magnetic field component perpendicular to the plane of reconnection. This component is known as the ‘guide field’ and it is normalized to the reconnecting field in the literature. The guide field controls the particle-scale dynamics of reconnection and influences the ensuing particle acceleration.

Component reconnection occurs in the Earth’s magnetosphere, along …
