Literary texts of medieval England feature trees as essential to the individual and communal identity as it intersects with nature, and the compelling qualities and organic processes associated with trees help vernacular writers interrogate the changing nature of this character. The early depiction of trees demonstrates an intimacy with nature that wanes after the tenth-century monastic revival, when the representation of trees as living, physical entities shifts toward their portrayal as allegorical vehicles for the Church's didactic use. With the emergence of new social categories in the late Middle Ages, the rhetoric of trees moves beyond what it means to forge a Christian identity to consider the role of a ruler and his subjects, the relationship between humans and nature, and the place of women in society. Taking as its fundamental premise that people in wooded regions develop a deep-rooted connection to trees, this dissertation connects medieval culture and the physical world to consider the variety of ways in which Anglo-Saxon and post-Norman vernacular manuscripts depict trees. A personal identification with trees, a desire for harmony between society and the environment, and a sympathy for the work of trees lead to the narrator's transformation in the Dream of the Rood. …

In the domain of music education philosophy there are, at present, two foundational systems that purport to be self-contained philosophies of music education. These are music education as aesthetic education, often referred to as MEAE, espoused by Bennett Reimer, and the praxial philosophy of music education posited by David Elliott. The debate between these two philosophies has been contentious and has had the effect of fracturing the philosophical underpinning of the music profession in an irreconcilable way. It is the purpose of this dissertation to introduce a third voice, that of the Danish philosopher Knut Løgstrup, to serve as a synergy between the philosophies of Reimer and Elliott and lead toward a framework of thinking for music education philosophy. I assert that the philosophies of Reimer and Elliott represent a modern articulation of an ancient dialectic between Platonic and Aristotelian ideals. Thus, the Reimer philosophy has its foundation in Platonic thought and Elliott has embraced an Aristotelian philosophical perspective. Løgstrup's position provides a third fundamental viewpoint that includes both Platonic and Aristotelian thinking and can therefore provide a synergy for these two music education philosophies. He refers to his philosophy as an ontological ethics. As a methodological approach, I utilize …

The search for a fundamental theory of matter and forces in the universe has ever since attracted the interest of physicists. The large success of the gauge theories in the description of low-energy phenomena nourishes the hope that gauge symmetries are the clue to a unified description of all fundamental processes at high energy scales. Particle collision experiments of the past decades have probed the structure of matter with increasing resolution. The phenomena observed in collision experiments at current energy scales are described with a large precision by the Standard Model of particle physics. Nevertheless, many open questions in the Standard Model suggest that it is an effective low-energy theory of a more fundamental theory: the numbers of free parameters of the model, the numbers of generations, the hierarchy between the electroweak scale and the Planck scale, the pending integration of gravity and the evolution of the strengths of the fundamental forces at large energy regimes. In addition, recent cosmological data suggest that the density of ordinary matter which is described by the Standard Model, corresponds only to a small fraction of the matter density in the universe. Many of the above mentioned problems are addressed by an extension of …

This dissertation is a study of morale in the western Confederacy from early 1864 until the Civil War's end in spring 1865. It examines when and why Confederate morale, military and civilian, changed in three important western states, Mississippi, Alabama, and Tennessee. Focusing on that time frame allows a thorough examination of the sources, increases the opportunity to produce representative results, and permits an assessment of the lingering question of when and why most Confederates recognized, or admitted, defeat. Most western Confederate men and women struggled for their ultimate goal of southern independence until Federal armies crushed those aspirations on the battlefield. Until the destruction of the Army of Tennessee at Franklin and Nashville, most western Confederates still hoped for victory and believed it at least possible. Until the end they drew inspiration from battlefield developments, but also from their families, communities, comrades in arms, the sacrifices already endured, simple hatred for northerners, and frequently from anxiety for what a Federal victory might mean to their lives. Wartime diaries and letters of western Confederates serve as the principal sources. The dissertation relies on what those men and women wrote about during the war - military, political, social, or otherwise - …
