Creator: Kim, Min Joung
Description: The etudes of Chopin are masterworks of the piano literature and are designed to go beyond mere technical exercises; moreover, each etude represents not only a technical study but also has a distinct musical character. Alarmingly, the current trend seems to be to assign the Chopin etudes at an increasingly young age to students who are not yet equipped either technically or musically to handle them. As Chopin’s pupil, Carl Mikuli, commented in the preface to his Chopin edition, the etudes were meant for “more advanced students.” If Chopin had intended his etudes for students at an intermediate level, he would have assigned them to most of his students; however, only a limited number of students had his permission to work on their master’s etudes. As a teacher, I have always felt the need to devise a systematic teaching plan to guide students to handle the challenges of these pieces both physically and musically. This study examines the repertoire which might help prepare a student to learn the etudes without overstraining his/her muscular and mental ability. Rooted in Chopin’s teaching and his recommendation of the pieces to learn before tackling the etudes themselves, this pedagogical study guide intends to help ...

Cosmology, Extraterrestrial Life, and the Development and Character of Western European Thought in the Seventeenth and Eighteenth Centuries

Cosmology, Extraterrestrial Life, and the Development and Character of Western European Thought in the Seventeenth and Eighteenth Centuries

Access: Use of this item is restricted to the UNT Community.
Date: August 2011
Creator: Simpson, Emily
Description: Cosmology, as an all-encompassing theoretical construction of universal reality, serves as one of the best indicators for a variety of philosophical, scientific, and cultural values. Within any cosmological system, the question of extraterrestrial life is an important element. Mere existence or nonexistence, however, only exposes a small portion of the ideological significance behind the contemplation of life outside of earth. The manners by which both believers and disbelievers justify their opinions and the ways they characterize other worlds and their inhabitants show much more about the particular ideas behind such decisions and the general climate of thought surrounding those who consider the topic. By exploring both physical and abstract structures of the universe, and specifically concepts on the plurality of worlds and extraterrestrial life, Western European thought in the seventeenth and eighteenth centuries reveals not an era of pure advancement and modernization, but as a time of both tradition and change.

Development of Indium Oxide Nanowires as Efficient Gas Sensors

Development of Indium Oxide Nanowires as Efficient Gas Sensors

Access: Use of this item is restricted to the UNT Community.
Date: December 2011
Creator: Gali, Pradeep
Description: Crystalline indium oxide nanowires were synthesized following optimization of growth parameters. Oxygen vacancies were found to impact the optical and electronic properties of the as-grown nanowires. Photoluminescence measurements showed a strong U.V emission peak at 3.18 eV and defect peaks in the visible region at 2.85 eV, 2.66 eV and 2.5 eV. The defect peaks are attributed to neutral and charged states of oxygen vacancies. Post-growth annealing in oxygen environment and passivation with sulphur are shown to be effective in reducing the intensity of the defect induced emission. The as-grown nanowires connected in an FET type of configuration shows n-type conductivity. A single indium oxide nanowire with ohmic contacts was found to be sensitive to gas molecules adsorbed on its surface.

Development of Silicon Nanowire Field Effect Transistors

Access: Use of this item is restricted to the UNT Community.
Date: December 2011
Creator: Nukala, Prathyusha
Description: An economically reliable technique for the synthesis of silicon nanowire was developed using silicon chloride as source material. The 30-40 micron long nanowires were found to have diameters ranging from 40 – 100 nm. An amorphous oxide shell covered the nanowires, post-growth. Raman spectroscopy confirmed the composition of the shell to be silicon-dioxide. Photoluminescence measurements of the as-grown nanowires showed green emission, attributed to the presence of the oxide shell. Etching of the oxide shell was found to decrease the intensity of green emission. n-type doping of the silicon nanowires was achieved using antimony as the dopant. The maximum dopant concentration was achieved by post-growth diffusion. Intrinsic nanowire parameters were determined by implementation of the as-grown and antimony doped silicon nanowires in field effect transistor configuration.

Date: May 2011
Creator: Choi, Da Jeong
Description: Dream of a Thousand Keys is a concerto for piano and orchestra, which consists of four movements presenting multiple dimensional meanings as suggested by the word "key." I trace the derivation of Korean traditional rhythmic cycles and numerical sequences, such as the Fibonacci series, that are used throughout the work, and explore the significant role of space between the soloist and piano that are emphasized in a theatrical aspect of the composition. The essay addresses the question of musical contrasts, similarities, and metamorphosis. Lastly, I cover terms and concepts of significant 21st-century compositional techniques that come into play in the analysis of this work.

Economic Mobility into the Planter Class in Texas, 1846-1860

Economic Mobility into the Planter Class in Texas, 1846-1860

Access: Use of this item is restricted to the UNT Community.
Date: December 2011
Creator: Nelson, Robert Nicholas
Description: This study examines upward economic mobility into the planter class in Texas during the antebellum statehood period, 1846-1860. Using quantitative methods to analyze data from census and tax records, this study addresses several questions regarding the property owning experience of Texas planters. Did any of the 1860 planters, men or women, rise to that status from another class? If so, how many rose from small slaveholder or small planter origins, and how many advanced from plain folk origins? In what ways did the amount and nature of wealth of these individuals change in the period studied? In what ways do these findings provide insights into the debate over planter dominance versus ‘plain folk’ inclusive herrenvolk democracy and the relationship between the planters and the other classes? Did the experiences of female planters differ from that of male planters? Did female planter experiences in Texas differ from female planters in other parts of the Old South? The results of these questions demonstrate that economic class mobility into the richest class was significant but limited and that women’s experiences were closely tied to those of male kin.

Gentrification in Oklahoma City:  Examining Urban Revitalization in Middle America

Gentrification in Oklahoma City: Examining Urban Revitalization in Middle America

Access: Use of this item is restricted to the UNT Community.
Date: August 2011
Creator: Petty, Clint C.
Description: Gentrification applies not only to the largest and oldest cities; it is a multi-scalar phenomenon playing out in smaller and less prominent settings as well. This study examines temporal changes in property values, demographic characteristics, and types of businesses in the central Oklahoma City area. A major urban revitalization project which began in 1993 created strong gentrification characteristics near the renewal's epicenter, the Bricktown entertainment district. Data suggest that several specific neighborhoods in the surrounding area exhibited rising property values, improving educational attainment rates, decreasing household sizes, and a shift toward cosmopolitan retail activity. While it is evident that Bricktown has been transformed, the socio-economic traits of surrounding neighborhoods have been altered by the ripple effects of urban renewal.

The Klezmer Influence in Paul Schoenfield’s Klezmer Rondos

Access: Use of this item is restricted to the UNT Community.
Date: December 2011
Creator: Trimble, Mark
Description: Paul Schoenfield’s Klezmer Rondos is a work for flute, male vocalist, and orchestra revised in 1994 according to the score given to me by the composer. A review of current research in klezmer heritage music is the starting point to place Klezmer Rondos in the context of art music infused with klezmer flavor. Klezmer music can be defined as the instrumental folk music of Eastern European Jews, however because of its adaptability and quality of assimilating other cultures within it, this heritage music is constantly in flux. By looking at the research in this field, I describe how the sound of klezmer music has evolved and how popular notions have been formed. The body of this research explores the main musical aspects of Klezmer Rondos that can be tied to the klezmer tradition: scales and thematic materials, improvisatory elements, ornamentation, and instrumentation. Klezmer Rondos moves beyond a simple arrangement of vernacular music for orchestra; it is a fusion of contemporary art music with the elements of klezmer style.

The Lexicographer's Daughter: A Memoir

Access: Use of this item is restricted to the UNT Community.
Date: May 2011
Creator: Lovell, Bonnie Alice
Description: This creative nonfiction dissertation is a memoir of the author's search for the somewhat mysterious hidden past of her father, the lexicographer Charles J. Lovell, who died in 1960, when the author was nine. Her father's early death left the author with many unanswered questions about his past and his family and so she undertakes a search to answer, if possible, some of those questions. Her search takes her to Portland, Maine; New Bedford, Massachusetts; and Pasadena, California, where she tries to discover the facts and uncover the forces that shaped her father's life. Along the way, she realizes how profoundly his death affected and shaped her own life, contributing to the theme of loss that pervades the memoir. In addition, she begins to realize how much her mother, Dixie Hefley Lovell, whose significance she previously overlooked, shaped her life. Ultimately, she comes to understand and accept that some of her questions are unanswerable.

The Martial Arts of Medieval Europe

The Martial Arts of Medieval Europe

Access: Use of this item is restricted to the UNT Community.
Date: August 2011
Creator: Price, Brian R.
Description: During the late Middle Ages and into the Renaissance, fighting books—Fechtbücher—were produced in northern Italy, among the German states, in Burgundy, and on the Iberian peninsula. Long dismissed by fencing historians as “rough and untutored,” and largely unknown to military historians, these enigmatic treatises offer important insights into the cultural realities for all three orders in medieval society: those who fought, those who prayed, and those who labored. The intent of this dissertation is to demonstrate, contrary to the view of fencing historians, that the medieval works were systematic and logical approaches to personal defense rooted in optimizing available technology and regulating the appropriate use of the skills and technology through the lens of chivalric conduct. I argue further that these approaches were principle-based, that they built on Aristotelian conceptions of arte, and that by both contemporary and modern usage, they were martial arts. Finally, I argue that the existence of these martial arts lends important insights into the world-view across the spectrum of Medieval and early Renaissance society, but particularly with the tactical understanding held by professional combatants, the knights and men-at-arms. Three treatises are analyzed in detail. These include the anonymous RA I.33 Latin manuscript in the Royal ...

Mary Jones: Last First Lady of the Republic of Texas

Access: Use of this item is restricted to the UNT Community.
Date: December 2011
Creator: Fish, Birney Mark
Description: Abstract This dissertation uses archival and interpretive methods to examine the life and contributions of Mary Smith McCrory Jones in Texas. Specifically, this project investigates the ways in which Mary Jones emerged into the public sphere, utilized myth and memory, and managed her life as a widow. Each of these larger areas is examined in relation to historiographicaly accepted patterns and in the larger context of women in Texas, the South, and the nation during this period. Mary Jones, 1819-1907, experienced many of the key early periods in Anglo Texas history. The research traces her family’s immigration to Austin’s Colony and their early years under Mexican sovereignty. The Texas Revolution resulted in her move to Houston and her first brief marriage. Following the death of her husband she met and married Anson Jones, a physician who served in public posts throughout the period of the Texas Republic. Over time Anson was politically and personally rejected to the point that he committed suicide. This dissertation studies the effects this death had upon Mary’s personal goals, her use of a widow’s status to achieve her objectives, and her eventual emergence as a “Professional Widow.” Mary Jones’s attempts to rehabilitate her husband’s public ...

Measuring Atmospheric Ozone and Nitrogen Dioxide Concentration by Differential Optical Absorption Spectroscopy

Measuring Atmospheric Ozone and Nitrogen Dioxide Concentration by Differential Optical Absorption Spectroscopy

Access: Use of this item is restricted to the UNT Community.
Date: December 2011
Creator: Jerez, Carlos J.
Description: The main objective was to develop a procedure based on differential optical absorption spectroscopy (DOAS) to measure atmospheric total column of ozone, using the automated instrument developed at the University of North Texas (UNT) by Nebgen in 2006. This project also explored the ability of this instrument to provide measurements of atmospheric total column nitrogen dioxide. The instrument is located on top of UNT’s Environmental Education, Science and Technology Building. It employs a low cost spectrometer coupled with fiber optics, which are aimed at the sun to collect solar radiation. Measurements taken throughout the day with this instrument exhibited a large variability. The DOAS procedure derives total column ozone from the analysis of daily DOAS Langley plots. This plot relates the measured differential column to the airmass factor. The use of such plots is conditioned by the time the concentration of ozone remains constant. Observations of ozone are typically conducted throughout the day. Observations of total column ozone were conducted for 5 months. Values were derived from both DOAS and Nebgen’s procedure and compared to satellite data. Although differences observed from both procedures to satellite data were similar, the variability found in measurements was reduced from 70 Dobson units, with ...

The “Nigger Trinity”: Engaging the Discourse in Post Civil Rights/Post 1960s America

Access: Use of this item is restricted to the UNT Community.
Date: December 2011
Creator: Bell, Adrian Shane
Description: The cultural and popular media landscape of the United States of America changed after the Civil-Rights movement of the 1960s. The word “Nigger” was changed during that same period of American history. There are several authors and a comic that helped change this word during the 1960s. The post Civil-Rights American has a different experience and understanding with this word than those born before 1970. This work triangulates the current cultural location of the word “Nigger,” “nigga,” and “the n-word” using linguistics, law, and two media case studies. The “Nigger” trinity is a model that adds value to the discourse that surrounds this one word in post civil-rights/post 1960s America.

Creator: Bush, Mary Gwen
Description: This dissertation is composed of two parts. Part I discusses the evolution of meditative poetry as a genre, with a particular emphasis on the influence of women poets and feminist critical theory. Part II is a collection of poems. Although several popular and critically-acclaimed poets working today write meditative poems, meditative poetry as a genre has not been systematically examined since M.H. Abrams’s essay on the meditative mode in Romantic poetry, “Structure and Style in the Greater Romantic Lyric.” Because one of the driving forces of meditative poetry is a longing for, or recognition of, a state of perception that lies between individual being and some form of universal ordering principle, meditative poetry might seem to be antithetical to a postmodern world that is fragmentary, contingent, and performative; indeed, earlier definitions of meditative poetry, tied to historical and cultural understandings of the individual and the Universal, no longer reflect “how we know” but only “how we knew.” However, this essay argues that there is a contemporary meditative structure that allows for a continued relationship between the individual and the Universal without resorting to the essentialism implicit in the genre as traditionally described. This new structure owes much to feminist theory, ...

Portrait of a southern Progressive: The political life and times of Governor Pat M. Neff of Texas, 1871-1952

Access: Use of this item is restricted to the UNT Community.
Date: May 2011
Creator: Stanley, Mark
Description: Pat M. Neff was a product of his political place and time. Born in Texas in 1871, during Reconstruction, he matured and prospered while his native state did the same as it transitioned from Old South to New South. Neff spent most of his life in Waco, a town that combined New South Progressivism with religious conservatism. This duality was reflected in Neff's own personality. On moral or religious issues, he was conservative. On economic and social issues, he was Progressive. He thus was a typical Southern Progressive who de-emphasized social and political change in favor of economic development. For instance, as governor from 1921 to 1925, his work to develop and conserve Texas' water resources brought urbanization and industrialization that made the New South a reality in the state. Neff was a devout Baptist which influenced his politics and philosophy. He was president of Baylor University, a Baptist institution, for fifteen years after leaving the governor s office and he led the Southern Baptist Convention (SBC) in the 1940s. He combined Progressive and Christian values as he argued for the establishment of the United Nations and advocated forgiveness and brotherhood after World War II. The war's end marked the ...

Scene Analysis Using Scale Invariant Feature Extraction and Probabilistic Modeling

Scene Analysis Using Scale Invariant Feature Extraction and Probabilistic Modeling

Access: Use of this item is restricted to the UNT Community.
Date: August 2011
Creator: Shen, Yao
Description: Conventional pattern recognition systems have two components: feature analysis and pattern classification. For any object in an image, features could be considered as the major characteristic of the object either for object recognition or object tracking purpose. Features extracted from a training image, can be used to identify the object when attempting to locate the object in a test image containing many other objects. To perform reliable scene analysis, it is important that the features extracted from the training image are detectable even under changes in image scale, noise and illumination. Scale invariant feature has wide applications such as image classification, object recognition and object tracking in the image processing area. In this thesis, color feature and SIFT (scale invariant feature transform) are considered to be scale invariant feature. The classification, recognition and tracking result were evaluated with novel evaluation criterion and compared with some existing methods. I also studied different types of scale invariant feature for the purpose of solving scene analysis problems. I propose probabilistic models as the foundation of analysis scene scenario of images. In order to differential the content of image, I develop novel algorithms for the adaptive combination for multiple features extracted from images. I ...

Southern Attitudes Toward the West, 1783 to 1803

Southern Attitudes Toward the West, 1783 to 1803

Access: Use of this item is restricted to the UNT Community.
Date: May 2011
Creator: Zemler, Jeffrey Allen
Description: This dissertation argues that the strong relationship that historians see between the South and West in the early 19th century, which allowed them to form what scholars have termed the Old South, had its origins in the twenty-year period after the American Revolution when a group of far-sighted southerners worked to form a political bond between the two regions. They did so by tirelessly defending the West and westerners against political and economic attacks, often from northerners but sometimes from people within their own region. Within the ongoing debate over the emergence of a southern consciousness, historians have overlooked one important factor in its development-the West. Although it would be incorrect to argue that southern consciousness began in the 1780s or 1790s, it would not be remiss to argue that southerners began to look at the trans-Appalachian West during this period as something more than just virgin territory. A few southerners, particularly James Madison, saw the South's political future entwined with the West's advancement and worked to ensure that a strong political relationship developed between the two regions. For people like Madison, this political merger of the two sections is what they meant when they talked about a "southern and ...

Access: Use of this item is restricted to the UNT Community.
Date: August 2011
Creator: McWilliams, Steven P.
Description: This study examined a new model of paclitaxel-induced neuropathic pain and the effects of systemic paclitaxel on the gap junction protein subunit Cx43 and potassium inwardly-rectifying channel Kir4.1 within the dorsal root ganglia. In the new neuropathic pain model, subplantar injections of paclitaxel resulted in decreased conduction velocities of A-beta fiber compound action potentials in the sciatic (5.9%) and tibial nerves (6.8%) as well as in M (10.6%) and H (10.2%) waves. By using repeated recordings it was found that following paclitaxel injection, conduction velocities in the contralateral plantar nerve increased (9.2%). Systemic injections of paclitaxel resulted in reduced Kir4.1 immunolabeling in the dorsal root ganglia compared to vehicle injections. This reduction was observed in total labeling (32.4%) as well as in areas of intense labeling (28.7%). Reductions in overall Cx43 immunolabeling (25%) and area (25%) following systemic paclitaxel injections were not statistically significant. The results of these studies suggest that subplantar injections of paclitaxel can result in reduced peripheral nerve conduction velocities. The results also show that a unilateral neuropathy can result in contralateral changes in conduction velocities. The effects of paclitaxel on reducing Kir4.1 levels suggest that neuropathic pain caused by paclitaxel may share mechanisms in common with ...
