William Harold Fletcher (b. 1923): His Life and Career in Music Education at Oklahoma Christian University, 1950-2012Stephens, April January 2012 (has links)
The purpose of this study was to examine the life of William Harold Fletcher (b. 1923) and his contributions to music education. The study is divided into a prologue, six chapters, and an epilogue: Early Life (1923-1941), College Studies and Military Service (1941-1948), Central Christian College: The Formative Years (1948-1960), Oklahoma Christian College: The Department of Music (1960-1980), The Department of Music (1980-2012), and Discussion and Conclusion. Fletcher, the first faculty member at Central Christian College (1950), dedicated his career to creating a strong music program for the college (now named Oklahoma Christian University). For the first thirteen years of its existence, Fletcher was the music department's sole full-time faculty member. He conducted, taught, and produced musical productions that were well received by the community. His contributions to music education include teacher, composer, conductor, and philosopher. Though not maintaining a highly politicized career, Fletcher's contribution to the field of music education remains substantial. His teaching methods and passion for music have inspired students for more than sixty years. Fletcher has received multiple honors for his teaching including the dedication of the Oklahoma Christian University music department as "The Harold and Mary Helon Fletcher Center for Music." This dissertation presents a glimpse of William Harold Fletcher the teacher, musician, composer, and free-spirited individual.

The Ethics of Joseph Fletcher And His Views Of Genetic control / Etik av Joseph Fletcher,och hans syn på genetisk kontrollFru, Fidelis Chungong January 2004 (has links)
<p>As we approach the 21st Century, our society is increasingly being faced with technological advances. One of such areas of advancement is the reasearch involving human genes. The human genome-mapping project(HGMP) started on the first of october 1990 with a group of over 350 labs. but by late 90's, many important advances had been discovered concerning how to improve the human specie. With these advances came ethical questions and concerns.Both moral and legal questions have been raised as to the effectiveness and safty of this technology. It is the contention of this paper to give a clearer meaning and understanding of the ethics of genetic control.As such I will discuss the wide spread fears and anxiety brought about by the introduction of this new technology. To make this aim more comprehensible, I will pay particular attention to Joseph Fletcher and his books on Genetic control, and Humanhood: Essays In Biomedical Ethics. Fletchers ardent support for genetic control has developed worldwide debates from both ethicists and philosophers as to the safty and efficiency of genetic engineering.</p>

Men on the road: beggars and vagrants in early modern drama (William Shakespeare, John Fletcher, and Richard Brome)Kim, Mi-Su 30 September 2004 (has links)
This dissertation examines beggars, gypsies, rogues, and vagrants presented in early modern English drama, with the discussion of how these peripatetic characters represent the discourses of vagrancy of the period. The first chapter introduces Tudor and early Stuart governments' legislation and proclamations on vagabondage and discusses these governmental policies in their social and economic contexts. The chapter also deals with the literature of roguery to point out that the literature (especially in the Elizabethan era) disseminated such a negative image of beggars as impostors and established the antagonistic atmosphere against the wandering poor. The second chapter explores the anti-theatrical aspect of the discourses of vagrancy. Along with the discussion of early playing companies' traveling convention, this chapter investigates how the long-held association of players with beggars is addressed in the plays that are dated from the early 1570s to the closing of the playhouses in 1642. In the third chapter I read Shakespeare's King Lear with the focus on its critical allusions to the discourses of vagrancy and interpret King Lear's symbolic experience of vagrancy in that context. The chapter demonstrates that King Lear represents the spatial politics embedded in the discourses of vagrancy and evokes a sympathetic understanding of the wandering poor. Chapter IV focuses on Beggars' Bush and analyzes the beggars' utopian community in the play. By juxtaposing the play with a variety of documents relating to the vagrancy issue in the early seventeen century, I contend that Beggars' Bush reflects the cultural aspirations for colonial enterprises in the early Stuart age. Chapter V examines John Taylor's conceptualization of vagrancy as a trope of travel and free mobility, and discusses the "wanderlust" represented in A Jovial Crew: Merry Beggars as an exemplary anecdote showing the mid seventeenth century's perceptions on vagrancy and spatial mobility. Thus, by exploring diverse associations and investments regarding vagrants, this study demonstrates that the early modern discourses of vagrancy have been informed and inflected by shifting economic, socio-historical, and national interests and demands.

Magneto-sensitive rubber in the audible frequency rangeBlom, Peter January 2006 (has links)
The dynamic behaviour in the audible frequency range of magneto-sensitive (MS) rubber is the focus of this thesis consisting of five papers A-E. Paper A presents results drawn from experiments on samples subjected to different constant shear strains over varying frequencies and magnetic fields. Main features observed are the existence of an amplitude dependence of the shear modulus referred to as the Fletcher-Gent effect for even small displacements, and the appearance of large MS effects. These results are subsequently used in Paper B and C to model two magneto-sensitive rubber isolators, serving to demonstrate how, effectively, by means of MS rubber, these can be readily improved. The first model calculates the transfer stiffness of a torsionally excited isolator, and the second one, the energy flow into the foundation for a bushing inserted between a vibrating mass and an infinite plate. In both examples, notable improvements in isolation are obtainable. Paper D presents a non-linear constitutive model of MS rubber in the audible frequency range. Characteristics inherent to magneto-sensitive rubber within this dynamic regime are defined: magnetic sensitivity, amplitude dependence, elasticity and viscoelasticity. A very good agreement with experimental values is obtained. In Paper E, the magneto-sensitive rubber bushing stiffness for varying degrees of magnetization is predicted by incorporating the non-linear magneto-sensitive audio frequency rubber model developed in Paper D, into an effective engineering formula for the torsional stiffness of a rubber bushing. The results predict, and clearly display, the possibility of controlling over a large range through the application of a magnetic field, the magneto-sensitive rubber bushing stiffness. / QC 20100816

Iterative Reconstruction Algorithms for Polyenergetic X-ray Computerized TomographyRezvani, Nargol 19 December 2012 (has links)
A reconstruction algorithm in computerized tomography is a procedure for reconstructing the attenuation coefficientscient, a real-valued function associated with the object of interest, from the measured projection data. Generally speaking, reconstruction algorithms in CT fall into two categories: direct, e.g., filtered back-projection (FBP), or iterative. In this thesis, we discuss a new fast matrix-free iterative reconstruction method based on a polyenergetic model.
While most modern x-ray CT scanners rely on the well-known filtered back-projection algorithm, the corresponding reconstructions can be corrupted by beam hardening artifacts. These artifacts arise from the unrealistic physical assumption of monoenergetic x-ray beams. In this thesis, to compensate, we use an alternative model that accounts for differential absorption of polyenergetic x-ray photons and discretize it directly. We do not assume any prior knowledge about the physical properties of the scanned object. We study and implement different solvers and nonlinear unconstrained optimization methods, such as a Newton-like method and an extension of the Levenberg-Marquardt-Fletcher algorithm. We explain how we can use the structure of the Radon matrix and the properties of FBP to make our method matrix-free and fast. Finally, we discuss how we regularize our problem by applying different regularization methods, such as Tikhonov and regularization in the 1-norm. We present numerical reconstructions based on the associated nonlinear discrete formulation incorporating various iterative optimization methods.
