The Fifth and Sixth Clarinet Concertos by Johann Melchior Molter: A Lecture Recital Together with Three Additional Recitals

Description: The dissertation consists of four recitals: one chamber music recital compiled from two years' series of chamber music performances in residence, two solo recitals, and one lecture recital. The repertoire of these programs was chosen with the intention of demonstrating the capability of the performer to deal with problems arising in works of varying types and of different historical periods. The lecture recital, The Fifth and Sixth Clarinet Concertos by Johann Melchior Molter, begins with perhaps the first performance of the Concerto No. 4 in D Major, Mus. Hs. 337, for clarinet in D with orchestral accompaniment reduced for piano. Bibliographical, historical and technical information is marshaled to justify the solo designation of Badische Landesbibliothek concerto manuscripts 334 and 328 to D clarinet rather than clarino. An investigation into the formal and stylistic aspects shows these two questionable works to be comparable to the composer's other four clarinet concertos. The analysis is followed by a short discussion of the problems involved in the transcription and performance of the works. The lecture concludes with the first performance of the Concerto No. 6 in D Major, Mus. Hs. 328, for clarinet in D with orchestral accompaniment reduced for piano.

Two-state and two-state plus continuum problems associated with the interaction of intense laser pulses with atoms

Description: Two mathematical methods are utilized (one a form of adiabatic approximation, and the other closely related to the Zener method from collision theory) in order to calculate the probability of three-photon ionization when strong counter propagating pulses are tuned very near a two-photon resonant state. In this case the inverted populations predicted by Grischkowsky and Loy for smooth laser pulses lead to larger ionization probabilities than would be obtained for a square pulse of equal peak power and energy per pulse. The line shape of the ionization probability is also quite unusual in this problem. A sharp onset in the ionization probability occurs as the lasers are tuned through the exact unperturbed two-photon resonance. Under proper conditions, the change can be from a very small value to one near unity. It occurs in a very small frequency range determined by the larger of the residual Doppler effect and the reciprocal duration of the pulse. Thus, the line shape retains a Doppler-free aspect even at power levels such that power broadening would dwarf even the full Doppler effect in the case of a square pulse of equal energy and peak power. The same mathematical methods have been used to calculate line shapes for the two-photon excitation of fluorescence when the atoms see a pulsed field due to their time of passage across a tightly focused cw laser beam. Thus,the mathematical methods used above permitted accurate analytical calculations under a set of very interesting conditions.

Female Friendship Films: A Post-Feminist Examination of Representations of Women in the Fashion Industry

Description: This thesis focuses on three fashion industry themed female friendship films: Pret-a-Porter/Ready to Wear (1994) by Robert Altman, The Devil Wears Prada (2006) by David Frankel, and The September Issue (2009) by R.J. Cutler. Female interpersonal relationships are complex – women often work to motivate, encourage and transform one another but can just as easily use tactics like intimidation, manipulation, and exploitation in order to save their own jobs and reputations. Through the lens of post-feminist theory, this thesis examines significant female interpersonal relationships in each film to illustrate how femininity is constructed and driven by consumer culture in the fashion industry themed films.

Surface Textures of Unglazed Pottery

Description: "This study, "Surface Textures of Unglazed Pottery," will record and evaluate a series of experiments performed that can be achieved on unglazed ceramic ware....The problem will be limited to experiments using a red clay from Horatio, Arkansas, a buff clay from Trenton, New Jersey, and a tan clay from Athens, Texas. The specimens will be fired at the temperature of 1643 degrees Fahrenheit...Experiments performed with the three clays will fall into three categories: (1) textures resulting from introduction of foreign matter into the clay (2) textures resulting from surface treatments of green ware and (3) textures resulting from surface treatments of bisque-fired ware. The experiments will be described and the fired clay specimens -- tiles 2"x2"x1/4" will be evaluated according to aesthetic and practical standards. Plates showing fired clay tiles resulting from the experiments will accompany the text [in volume 2]."-- leaf 1.

Good Nature and Prudence: Moral Concepts of Character in Eighteenth-Century Fiction

Description: To appreciate fully the ethical dimensions inherent in the literature of the eighteenth century it is necessary to understand the moral bias of an author, a bias often best ascertained by a study of the treatment he accords good nature and prudence. Although several scholarly articles and portions of longer studies recognize the importance of these virtues for individual writers, no single work has appeared which traces fully the history of the idea of good nature and prudence as complementary virtues in the eighteenth century. The present study provides a systematic analysis of these virtues as treated in theology, ethical philosophy, and fiction from the later seventeenth century to about 1800.

Calculation of transport coefficients in an axisymmetric plasma

Description: A method of calculating the transport coefficient in an axisymmetric toroidal plasma is presented. This method is useful in calculating the transport coefficients in a Tokamak plasma confinement device. The particle density and temperature are shown to be a constant on a magnetic flux surface. Transport equations are given for the total particle flux and total energy flux crossing a closed toroidal surface. Also transport equations are given for the toroidal magnetic flux. A computer code was written to calculate the transport coefficients for a three species plasma, electrons and two species of ions. This is useful for calculating the transport coefficients of a plasma which contains impurities. It was found that the particle and energy transport coefficients are increased by a large amount, and the transport coefficients for the toroidal magnetic field are reduced by a small amount.

An Empirical Investigation of Marascuilo's Ú₀ Test with Unequal Sample Sizes and Small Samples

Description: The study seeks to determine the effect upon the Marascuilo Ú₀ statistic of violating the small sample assumption. The study employed a Monte Carlo simulation technique to vary the degree of sample size and unequal sample sizes within experiments to determine the effect of such conditions, Twenty-two simulations, with 1200 trials each, were used. The following conclusion appeared to be appropriate: The Marascuilo Ú₀ statistic should not be used with small sample sizes and it is recommended that the statistic be used only if sample sizes are larger than ten.

Motivation and Resilience in Art Education: Insight and Inspiration From the Lives and Careers of Two Taiwanese College Art Teachers

Description: This narrative study explores how two Taiwanese college art teachers’ lives and teaching experiences illustrate the ways they cultivate resilience and motivation to sustain professional commitments amidst challenges in their teaching careers. I use the life story interview as my methodology and a three-dimensional space approach to code and analyze my data to retell their stories about how resilience and motivation have guided them as they negotiated dilemmas in teaching. The participants’ stories demonstrate that in order to be motivated, teachers must satisfy their basic needs, which, in the language of Maslow’s need theory, include secure income, safety, love and belonging, respect, and personal accomplishment. To be resilient, art teachers need to facilitate self-efficacy as an essential belief to face challenges, and they also must gain support from family members, students, school administrators, and fellow members of professional organizations as external support resources. This study also illuminates the significance of international educational exchanges, the teaching knowledge constructed through layers of life and professional experience, and the importance of creating dialogue to address teachers’ challenges. Recommendations for future study include exploring further the relationship between motivation and resilience, specifying how gender difference affects the ways participants tell their stories, investigating how teachers in diverse cultural and geographical settings develop motivation and resilience, considering how teachers construct career-affirming memories from both positive and negative life experiences, and exploring uses of social media to engage a broader audience, sharing participants’ stories without the limitations of time and space.

Rational Design of Metal-organic Electronic Devices: a Computational Perspective

Description: Organic and organometallic electronic materials continue to attract considerable attention among researchers due to their cost effectiveness, high flexibility, low temperature processing conditions and the continuous emergence of new semiconducting materials with tailored electronic properties. In addition, organic semiconductors can be used in a variety of important technological devices such as solar cells, field-effect transistors (FETs), flash memory, radio frequency identification (RFID) tags, light emitting diodes (LEDs), etc. However, organic materials have thus far not achieved the reliability and carrier mobility obtainable with inorganic silicon-based devices. Hence, there is a need for finding alternative electronic materials other than organic semiconductors to overcome the problems of inferior stability and performance. In this dissertation, I research the development of new transition metal based electronic materials which due to the presence of metal-metal, metal-?, and ?-? interactions may give rise to superior electronic and chemical properties versus their organic counterparts. Specifically, I performed computational modeling studies on platinum based charge transfer complexes and d10 cyclo-[M(?-L)]3 trimers (M = Ag, Au and L = monoanionic bidentate bridging (C/N~C/N) ligand). The research done is aimed to guide experimental chemists to make rational choices of metals, ligands, substituents in synthesizing novel organometallic electronic materials. Furthermore, the calculations presented here propose novel ways to tune the geometric, electronic, spectroscopic, and conduction properties in semiconducting materials. In addition to novel material development, electronic device performance can be improved by making a judicious choice of device components. I have studied the interfaces of a p-type metal-organic semiconductor viz cyclo-[Au(µ-Pz)]3 trimer with metal electrodes at atomic and surface levels. This work was aimed to guide the device engineers to choose the appropriate metal electrodes considering the chemical interactions at the interface. Additionally, the calculations performed on the interfaces provided valuable insight into binding energies, charge redistribution, change in the energy ...

A New Chromophoric Organic Molecule Toward Improved Molecular Optoelectronic Devices

Description: The characterization of 2,3,6,7,10,11-hexabromotriphenylene, Br6TP, is presented toward its potential use as an n-type organic semiconductor and metal-free room temperature phosphor. The crystal structure shows both anisotropic two-dimensional BrBr interactions and inter-layer ?-stacking interactions. Photophysical characteristics were evaluated using solid-state photoluminescence and diffuse reflectance spectroscopies, revealing significantly red-shifted excitations in the visible region for the yellow solid material (compared to ultraviolet absorption bands for the colorless dilute solutions). Correlation of spectral, electrochemical, and computational data suggest the presence of an n-type semiconducting behavior due to the electron-poor aromatic ring. The material shows excellent thermal stability as demonstrated by thermogravimetric analysis and infrared spectra of a thin film deposited by thermal evaporation. The potential for Br6TP and its analogues toward use in several types of photonic and electronic devices is discussed.

Practical Astronomy

Description: This dissertation is a collection of poems preceded by a critical preface. The preface considers Anthony’s Hecht’s long poem, “The Venetian Vespers,” and the ways in which the temporally unsettled situation of the poem’s speaker parallels a problem facing narrative-meditative poets. The preface is divided into two main sections that explore divisions of this larger conflict. The first discusses the origins and effects of the speaker’s uprootedness in time, and the ways in which he tries to both combat and embrace this dislocation by temporarily losing himself in the immediacy of observing visual art. In this section I connect the dilemma of the speaker, who wishes to escape his memory by focusing outwards, to the dilemma of a representational poet who, despite his position towards the past, must necessarily confront or recollect memories and emotions in order to create authentic descriptions or characters. The second section focuses on the production and appreciation of artistic works (both visual and literary) and how the meaning, production and appreciation of beauty are inseparable from its existence within the physical limits of time. Here I discuss the significance of Hecht’s character who is surrounded with beauty yet describes himself as a person who only observes and does not create anything. Through this character, I argue that Hecht reveals a fundamental conflict that exists between artistic creation and chronological time, and that his poem embodies a particular and paradoxical view of beauty that resonates deeply with the motivations and struggles of writing poems.

Nonparametric Estimation of Receiver Operating Characteristic Surfaces Via Bernstein Polynomials

Description: Receiver operating characteristic (ROC) analysis is one of the most widely used methods in evaluating the accuracy of a classification method. It is used in many areas of decision making such as radiology, cardiology, machine learning as well as many other areas of medical sciences. The dissertation proposes a novel nonparametric estimation method of the ROC surface for the three-class classification problem via Bernstein polynomials. The proposed ROC surface estimator is shown to be uniformly consistent for estimating the true ROC surface. In addition, it is shown that the map from which the proposed estimator is constructed is Hadamard differentiable. The proposed ROC surface estimator is also demonstrated to lead to the explicit expression for the estimated volume under the ROC surface . Moreover, the exact mean squared error of the volume estimator is derived and some related results for the mean integrated squared error are also obtained. To assess the performance and accuracy of the proposed ROC and volume estimators, Monte-Carlo simulations are conducted. Finally, the method is applied to the analysis of two real data sets.

The Harmonic Interval of the Seventh in the Works of Representative Composers of Italian Madrigals, 1542-1614

Description: This study is an attempt to shed some light on the treatment of one dissonance—the seventh—in the works of the following composers: Cipriano de Rore (1516-1565); Philippe de Monte (1521-1603); Giaches de Wert (1535-1596); Luca Marenzio (1553-1599); Carlo Gesualdo (ca. 1560-1613); and Claudio Monteverdi (1567-1643). The purpose of this thesis is to discover (1) the frequency of occurrence of primary (relatively accented) sevenths and their inversions (^ chords, etc.) in a selection of each composer's madrigals; and (2) the methods of handling sevenths employed by each composer, with particular emphasis on the relationship between these methods and sixteenth century theory.

Dolores Dyer: Women's Basketball and the American Dream

Description: Dolores Dyer played from 1952-1953 for the Texas Cowgirls, a barnstorming women's basketball team that provided a form of entertainment popular throughout the United States in that era. The story of Dyer's life demonstrates how a woman could attempt to achieve the American dream—a major theme in American history—through success in athletic competition. Dyer's participation with the Texas Cowgirls also provides a look into the circumstances that limited women's participation in professional sport during the mid-twentieth century. Women's sports studies, although some are very thorough, have gaps in the research, and women's barnstorming basketball is one of the areas often overlooked. In light of this gap, this thesis relies on a variety of sources, including primary documents from unpublished collections, archived materials, and original oral histories from several members of the Texas Cowgirls team. This thesis contains analysis of the socioeconomic factors that influenced Dolores Dyer's maturation into a professional basketball player, examines what the American dream meant to her, and evaluates the extent to which she achieved it. Overall, it constructs a social history that can serve as a foundational source for further study of women in sports during the twentieth century.

Design, Synthesis and Screening of Homoleptic and Heteroleptic Platinum(ii) Pyridylazolate Complexes for N-type Semiconducting and Light-emitting Devices

Description: A series of heteroleptic and homoleptic platinum(II) complexes has been synthesized and characterized towards their use in thin film devices such as organic light-emitting diodes (OLEDs) and organic thin film transistors (OTFTs). Pyridylpyrazolate- and pyridyltetrazolate-containing ligands were selected due to their structural rigidity and ease of functionalization. Single-crystal x-ray diffraction studies of two selected heteroleptic complexes show strong aggregation with preferential stacking into vertical columns with a varying degree of overlap of the neighboring square planar molecular units. It is shown that the close proximity of the molecules to one another in the stack increases semiconducting character, phosphorescence quantum yields, and shorter radiative lifetimes. The potential for these materials towards incorporation into high-efficiency doping free white OLEDs (DFW-OLEDs) for solid-state lighting and display applications has been realized and will be expanded upon by present and future embodiments of materials in this thesis.

Social Networking, Workplace, and Entertainment Literacies: the Out-of-school Literate Lives of Newcomer Latina/o Adolescents

Description: Studies indicate that Latina/o immigrant youth engage in a wide range of sophisticated literacy practices outside of school that are often transnational, crossing various linguistic, cultural, and social spaces. Technology has further afforded immigrant youth the opportunity to develop transnational capabilities which are rare in the mainstream population, yet needed in the 21st century of global connectedness. However, Latino immigrant youth drop out of school at disproportional rates, suggesting that their literacy practices are not recognized or valued by the educational system. Using a New Literacy Studies perspective that recognizes multiple literacies that are meaningful within their sociocultural traditions, this collective case study investigated the range, form, and purpose of the out-of-school literacies of four Latina/o adolescent English Learners who are new arrivals. The qualitative methodology employed constructivist interviews, digital and actual artifacts, and observations. Findings demonstrated that the most prevalent out-of-school literacies the participants practice take place on the social networking site of Facebook, in their workplaces, and through the entertainment media sources of music and television. A cross-case analysis suggests that the literacy practices in these spaces have unique and purposeful roles for the individuals that allow them to connect to their home countries and maintain their Latina/o identities. Additionally, the participants use their out-of-school literacy practices to acquire English, support themselves, and establish a place to succeed. The five aforementioned spaces that their Facebook, workplace, and entertainment literacy practices fill are virtually absent from their in-school literacies. This study suggests literacy pedagogy and research must not continue to impose a narrow monolingual, monocultural, monoliterate, and monomodal view of Latina/o immigrant students which essentially divests them of their greatest resources. Their literacy practices demonstrate that they are transnational, transcultural, emergent bilinguals who competently engage in multimodal means of communication across multiple linguistic, cultural, social, and geographic borders.

A Revolution in Warfare? the Army of the Sambre and Meuse and the 1794 Fleurus Campaign

Description: During the War of the First Coalition, the Army of the Sambre and Meuse, commanded by Jean-Baptiste Jourdan, played the decisive role against Coalition forces in the Low Countries. Created in June 1794, the army defeated the Allies at the battle of Second Fleurus on 26 June 1794 and commenced the Coalition’s retreat to the Rhine River. At the end of the year, Jourdan led the army to winter quarters along the left bank of the Rhine and achieved France’s historically momentous “natural frontier.” Despite its historical significance, the Army of the Sambre and Meuse has suffered from scant historical attention. Based largely on archival research, this thesis provides a detailed examination of the army’s performance during the Fleurus campaign. In addition, this thesis pursues several broader themes. A detailed study of the Sambre and Meuse Army provides insight into institutional military change during the late eighteenth century. While historians traditionally argue that the French Revolution inaugurated an attendant “revolution in military affairs,” this thesis presents evidence of evolutionary changes and continuities. Another important theme is the question of the combat effectiveness of French field armies during the Revolutionary epoch. Although historians typically present the French armies as unique and superior to their Old Regime opponents, this thesis demonstrates the effective parity between the armies of Revolutionary France and the Old Regime on the battlefield.

Southern Roots, Western Foundations: the Peculiar Institution and the Livestock Industry on the Northwestern Frontier of Texas, 1846-1864

Description: This dissertation challenges Charles W. Ramsdell's needless war theory, which argued that profitable slavery would not have existed west of the 98th meridian and that slavery would have died a natural death. It uses statistical information that is mined from the county tax records to show how slave-owners on the northwestern frontier of Texas raised livestock rather than market crops, before and during the Civil War. This enterprise was so strong that it not only continued to expand throughout this period, but it also became the foundation for the recovery of the Texas economy after the war.

The Useful Arts

Description: This creative nonfiction dissertation is a series of braided narratives that chronicle the author's career as a trombonist in the John Smith Ensemble. As an amateur trombonist, the author is shocked to be hired as a professional musician for an orchestra that plays on PBS and at Carnegie Hall. She quickly realizes, however, that the job requires her to play the trombone quietly in front of an unplugged microphone while a CD recording of another, more talented trombonist is blasted out toward an unknowing audience. The job also requires the author to tour around America. The scenes of from this tour are braided with scenes wherein she reflects on her life as a professional fake musician and her past failed attempts at getting a job.
