The Solo Style Of Jazz Clarinetist Johnny Dodds: 1923 - 1938, Patricia A. Martin Jan 2003

The Solo Style Of Jazz Clarinetist Johnny Dodds: 1923 - 1938, Patricia A. Martin

LSU Doctoral Dissertations

The purpose of this study is to explore the personality, background, influence and playing style of Johnny Dodds (1892-1940), a New Orleans jazz clarinetist. Jazz is an art form that has been passed down aurally for over a hundred years. Although the development of jazz and the performers who played it have been the subject for numerous jazz historians, there are still scant resources available for a musician to learn jazz clarinet style. The ease with which a musician can emulate an early jazz clarinetist depends on the amount of time devoted to listening and emulating whatever recordings are available. …

Southern Opposition To Civil Rights In The United States Senate: A Tactical And Ideological Analysis, 1938-1965, Keith M. Finley Jan 2003

Southern Opposition To Civil Rights In The United States Senate: A Tactical And Ideological Analysis, 1938-1965, Keith M. Finley

LSU Doctoral Dissertations

Contrary to many historical accounts that depict white resistance to civil rights legislation in the United States Senate as relying exclusively on filibusters and overt racism, southern senators adopted a more moderate approach in the late 1930s when they realized that civil rights activism would continue until Jim Crow collapsed. Following strategic delay, a tactical model that enabled them to thwart civil rights advances for decades, they granted minor concessions on bills only tangentially related to civil rights and emasculated more substantive measures, rather than always utilizing the filibuster. The level of northern support for a given civil rights proposal …

Investigation Of Bond Slip Between Concrete And Steel Reinforcement Under Dynamic Loading Conditions, John Henry Weathersby Jan 2003

Investigation Of Bond Slip Between Concrete And Steel Reinforcement Under Dynamic Loading Conditions, John Henry Weathersby

LSU Doctoral Dissertations

Structural failures during recent earthquakes and terrorist attacks have demonstrated shortcomings in the design procedures for reinforced concrete structures. Earlier research has demonstrated that a major limitation of the Finite Element (FE) modeling of the response of reinforced concrete is the accurate modeling of the interaction of the concrete with the steel reinforcement. Presently, there are insufficient data on the dynamic nonlinear interaction between the concrete material and the steel reinforcement to develop a numerical model of this interaction. The primary objective of this study was to experimentally investigate the dynamic interaction (bond slip) of reinforcement with concrete and gain …

Pollen Dispersal And Deposition In The High-Central Andes, South America, Carl A. Reese

LSU Doctoral Dissertations

This dissertation uses fossil (ice core) and modern pollen samples collected throughout the central Andes to investigate the paleovegetational changes in the area as well as the modern dispersal and depositional characteristics of pollen in this region of South America. The results of the fossil pollen study on Mt. Sajama reveal a vegetation history that closely corresponds to the chemical and physical records already published from the mountain. Pollen becomes abundant after 15,000 B.P. and suggests the occurrence of two distinct phases between 15,000 and 12,000 B.P. (a short interstadial and the Deglacial Climatic Reversal). After 12,000 B.P., there is …

Role Of Endothelin-1 In The Gastrointestinal Tract Of Horses In Health And Disease, Ramaswamy Monickarasi Chidambaram Jan 2003

Role Of Endothelin-1 In The Gastrointestinal Tract Of Horses In Health And Disease, Ramaswamy Monickarasi Chidambaram

LSU Doctoral Dissertations

Gastrointestinal tract disease is the leading natural cause of death in horses and horses with ischemic intestinal disease have the greatest mortality. We hypothesized there is basal synthesis of endothelin-1 (ET-1) in the intestinal tract of healthy horses that is likely involved in regulating vasomotor tone, secretion and motility and that ET-1 synthesis increases with gastrointestinal tract disease, which may be involved in the pathophysiology of these disorders. Plasma ET-like immunoreactivity was increased in horses with naturally-acquired gastrointestinal disease, compared with normal horses; values were greatest in horses with large intestinal strangulation obstruction, enterocolitis and peritonitis. There was an association …

Atomic And Electronic Structure Of Bulk Intermetallic And Heteroepitaxially Grown Surface Alloys, Orhan Kizilkaya

LSU Doctoral Dissertations

It has been well documented that the surfaces of solids may differ from their bulk counterpart. The symmetry that a bulk possesses is broken at the surface. Due to this broken symmetry in the reduced dimension of the surface, the energetic of the surface also differs from the bulk counterpart. Reconstruction, charge redistribution, and surface alloying are phenomena that minimize the surface free energy. Surface properties of scientifically and technologically important bimetallic systems are the main focus of this dissertation. Specifically, surfaces of bulk alloy or heteroepitaxially grown metal-on-metal systems have been investigated primarily with two indispensable surface techniques, scanning …

The Relationship Between Obstructive Sleep Apnea Syndrome And Insomnia: Implications For Treatment, Danae L. Drab Jan 2003

The Relationship Between Obstructive Sleep Apnea Syndrome And Insomnia: Implications For Treatment, Danae L. Drab

LSU Doctoral Dissertations

Obstructive sleep apnea syndrome (OSAS) is a sleep-disordered breathing condition that causes disrupted sleep. Although OSAS is most often associated with daytime hypersomnolence, a number of OSAS patients complain of insomnia, i.e., disorders of initiating or maintaining sleep. If the insomnia in patients with OSAS is secondary to the medical condition, then it would be expected to abate with the successful treatment of OSAS. If, however, the insomnia is primarily of a psychological nature, thus considered primary or psychophysiological insomnia, little to no change in insomnia symptoms would be expected after the treatment of OSAS. The present study examined the …

Radical Dialectics In The Experimental Poetry Of Berssenbrugge, Hejinian, Harryman, Weiner, And Scalapino, Camille Martin

LSU Doctoral Dissertations

In this dissertation, I focus on the work of five contemporary experimental poets - Mei-mei Berssenbrugge, Lyn Hejinian, Carla Harryman, Hannah Weiner, and Leslie Scalapino - in order to demonstrate various aspects of a philosophical dynamic at work in their poetry. The critical debates surrounding experimental poetry often tend to be structured as a dualistic opposition with, for example, the forces of coherence, narrative linearity, and transparent referentiality on one side, and the forces of semantic disruption, narrative discontinuity, and linguistic materiality on the other. On each side, critics attempt to bolster the essential value of one term or set …
