Fractus I for Trumpet in C and Electronic Sound: A Critical Examination of the Compositional Process

Description: Fractus I is a composition for trumpet in C and live electronic sound. The electronics were primarily created using SuperCollider, an environment and programming language for real time audio synthesis. This project investigates SuperCollider's pattern and task functionality as a means of supporting and enriching the compositional process. Fractus I develops several different code architectures in order to randomize as well as synchronize various musical elements. The piece exploits SuperCollider as both an audio synthesis tool and a performance conduit. Additionally, the nature of SuperCollider's patterns and tasks influences the form and content of the composition. The project underscores SuperCollider as a powerful, versatile and open-ended tool for musical composition and examines future directions and improvements.

A Framework for Analyzing and Optimizing Regional Bio-Emergency Response Plans

Description: The presence of naturally occurring and man-made public health threats necessitate the design and implementation of mitigation strategies, such that adequate response is provided in a timely manner. Since multiple variables, such as geographic properties, resource constraints, and government mandated time-frames must be accounted for, computational methods provide the necessary tools to develop contingency response plans while respecting underlying data and assumptions. A typical response scenario involves the placement of points of dispensing (PODs) in the affected geographic region to supply vaccines or medications to the general public. Computational tools aid in the analysis of such response plans, as well as in the strategic placement of PODs, such that feasible response scenarios can be developed. Due to the sensitivity of bio-emergency response plans, geographic information, such as POD locations, must be kept confidential. The generation of synthetic geographic regions allows for the development of emergency response plans on non-sensitive data, as well as for the study of the effects of single geographic parameters. Further, synthetic representations of geographic regions allow for results to be published and evaluated by the scientific community. This dissertation presents methodology for the analysis of bio-emergency response plans, methods for plan optimization, as well as methodology for the generation of synthetic geographic regions.

Framework for Evaluating Dynamic Memory Allocators Including a New Equivalence Class Based Cache-conscious Allocator

Description: Software applications’ performance is hindered by a variety of factors, but most notably by the well-known CPU-memory speed gap (often known as the memory wall). This results in the CPU sitting idle waiting for data to be brought from memory to processor caches. The addressing used by caches cause non-uniform accesses to various cache sets. The non-uniformity is due to several reasons, including how different objects are accessed by the code and how the data objects are located in memory. Memory allocators determine where dynamically created objects are placed, thus defining addresses and their mapping to cache locations. It is important to evaluate how different allocators behave with respect to the localities of the created objects. Most allocators use a single attribute, the size, of an object in making allocation decisions. Additional attributes such as the placement with respect to other objects, or specific cache area may lead to better use of cache memories. In this dissertation, we proposed and implemented a framework that allows for the development and evaluation of new memory allocation techniques. At the root of the framework is a memory tracing tool called Gleipnir, which provides very detailed information about every memory access, and relates it back to source level objects. Using the traces from Gleipnir, we extended a commonly used cache simulator for generating detailed cache statistics: per function, per data object, per cache line, and identify specific data objects that are conflicting with each other. The utility of the framework is demonstrated with a new memory allocator known as equivalence class allocator. The new allocator allows users to specify cache sets, in addition to object size, where the objects should be placed. We compare this new allocator with two well-known allocators, viz., Doug Lea and Pool allocators.

A Framework of Automatic Subject Term Assignment: An Indexing Conception-Based Approach

Description: The purpose of dissertation is to examine whether the understandings of subject indexing processes conducted by human indexers have a positive impact on the effectiveness of automatic subject term assignment through text categorization (TC). More specifically, human indexers' subject indexing approaches or conceptions in conjunction with semantic sources were explored in the context of a typical scientific journal article data set. Based on the premise that subject indexing approaches or conceptions with semantic sources are important for automatic subject term assignment through TC, this study proposed an indexing conception-based framework. For the purpose of this study, three hypotheses were tested: 1) the effectiveness of semantic sources, 2) the effectiveness of an indexing conception-based framework, and 3) the effectiveness of each of three indexing conception-based approaches (the content-oriented, the document-oriented, and the domain-oriented approaches). The experiments were conducted using a support vector machine implementation in WEKA (Witten, & Frank, 2000). The experiment results pointed out that cited works, source title, and title were as effective as the full text, while keyword was found more effective than the full text. In addition, the findings showed that an indexing conception-based framework was more effective than the full text. Especially, the content-oriented and the document-oriented indexing approaches were found more effective than the full text. Among three indexing conception-based approaches, the content-oriented approach and the document-oriented approach were more effective than the domain-oriented approach. In other words, in the context of a typical scientific journal article data set, the objective contents and authors' intentions were more focused that the possible users' needs. The research findings of this study support that incorporation of human indexers' indexing approaches or conception in conjunction with semantic sources has a positive impact on the effectiveness of automatic subject term assignment.

Framework to Evaluate Entropy Based Data Fusion Methods in Supply Chain Management

Description: This dissertation explores data fusion methodology to deduce an overall inference from the data gathered from multiple heterogeneous sources. Typically, if there existed a data source in which the data were reliable and unbiased, then data fusion would not be necessary. Data fusion methodology combines data form multiple diverse sources so that the desired information - such as the population mean - is improved despite redundancies, inaccuracies, biases, and inflated variability in the data. Examples of data fusion include estimating average demand from similar sources, and integrating fatality counts from different media sources after a catastrophe. The approach in this study combines "inputs" from distinct sources so that the information is "fused." Another way of describing this process is "data integration." Important assumptions are 1. Several sources provide "inputs" for information used to estimate parameters of a probability distribution. 2. Since distributions for the data from the sources are heterogeneous, some sources are less reliable. 3. Distortions, bias, censorship, and systematic errors may be more prominent in data from certain sources. 4. The sample size of sources data, number of "inputs," may be very small. Examples of information from multiple sources are abundant: traffic information from sensors at intersections, multiple economic indicators from various sources, demand data for product using similar retail stores as sources, polling data from various sources, and disaster count of fatalities from different media sources after a catastrophic event. This dissertation seeks to address a gap in the operations literature by addressing three research questions regarding entropy base data fusion (EBDF) approaches to estimation. Three separate, but unifying, essays address the research questions for this dissertation. Essay 1 provides an overview of supporting literature for the research questions. A numerical analysis of airline maximum wait time data illustrates the underlying issues involved in EBDF methods. This ...

Framing Bilingual Education Policy: Articulation and Implementation in Texas

Description: Language education policy and its implementation have been controversial and ongoing issues throughout the United States, especially in the border state of Texas, with its large population of students who are learning English. This dissertation reports two studies, the first of which was a frame analysis of problems and solutions as represented by the five bills amending the Texas Education Code with regard to bilingual education and English as a second language programs. These laws, passed in 1969, 1973, 1975, 1981, and 2001, have been enacted since 1968, the year the Bilingual Education Act (BEA) was passed. The problem framed consistently by these state policy documents was inadequate instruction for children who come to school speaking languages other than English. More variability was seen in the framing of solutions, with approaches changing from the authorization of instruction in languages other than English, to the establishment of mandated bilingual programs, to the extension of special language programs, and to the establishment of dual language immersion programs. The primary ideology influencing the policy documents was the monolingual English ideology; however, alternative ideologies are apparent in the policies that allow for dual language immersion programs. Geographic information systems (GIS) analysis was used in the second study to investigate the geographic locations of particular programs and the demographics of students they served. Choropleth maps showed variability in program distribution across the state with distinct patterns apparent in only two programs. The maps indicated that districts with high percentages of student enrollment in one-way dual language programs tended to be located in and near the major metropolitan areas, whereas many districts offering early exit transitional bilingual programs tended to be located along the Texas-Mexico border. Despite the literature on bilingual/ESL program effectiveness, the predominant program in the border region of Texas is among those considered ...

Framing Femininity as Insanity: Representations of Mental Illness in Women in Post-Classical Hollywood

Description: From the socially conservative 1950s to the permissive 1970s, this project explores the ways in which insanity in women has been linked to their femininity and the expression or repression of their sexuality. An analysis of films from Hollywood's post-classical period (The Three Faces of Eve (1957), Lizzie (1957), Lilith (1964), Repulsion (1965), Images (1972) and 3 Women (1977)) demonstrates the societal tendency to label a woman's behavior as mad when it does not fit within the patriarchal mold of how a woman should behave. In addition to discussing the social changes and diagnostic trends in the mental health profession that define “appropriate” female behavior, each chapter also traces how the decline of the studio system and rise of the individual filmmaker impacted the films' ideologies with regard to mental illness and femininity.

France and the Little Entente, 1936-1937: the Work of Yvon Delbos

Description: This thesis studies France"s relations with the Little Entente during the term of Foreign Minister Delbos. It relies primarily on published diplomatic papers and memoirs. It discusses Delbos's background, the histories of Czechoslovakia, Yugoslavia, and Rumania from 1919-1936, and the formation of the Little Entente. The thesis focuses on France's efforts after the Rhineland crisis to strengthen her Eastern European alliances. Delbos chose the Little Entente over the Soviet Union as France's primary Eastern European alliance. Delbos's proposed Mutual Assistance Pact between France and the Little Entente and his Eastern European trip in December, 1937, failed owing to Yugoslavian and Rumanian opposition. German economic domination and intimidation of, and British disinterest in, Eastern Europe contributed to Yugoslavian and Rumanian rejection of France's overtures.

France and the United States: Borrowed and Shared National Symbols

Description: This thesis analyzes and demonstrates the similarities and differences between some of the national symbols of France and the United States. This includes the shared and borrowed aspects of each one and the ways in which each culture is reflected through, and built around them. The flags, national anthems, and several national icons such as France's Marianne and Uncle Sam are discussed. This analysis deals with the historical contexts and cultural meanings of the symbols, showing the changes each has undertaken in form and in national and international importance. Through the study of national symbols, this thesis reveals the similarities along with the differences between the two nations, which are often perceived as being highly dissimilar and even opposing in belief systems, cultures, and histories.

Frances Farenthold: Texas' Joan of Arc

Description: Born in 1926, Frances "Sissy" Tarlton Farenthold began her exploration of politics at a young age. In 1942, Farenthold graduated from Hockaday School for Girls. In 1945, she graduated from Vassar College, and in 1949, she graduated from the University of Texas School of Law. Farenthold was a practicing lawyer, participated in the Corpus Christi Human Relations Commission from 1964 to 1969, and directed Nueces County Legal Aid from 1965 to 1967. In 1969, she began her first term in the Texas House of Representatives. During her second term in the House (1971-1972), Farenthold became a leader in the fight against government corruption. In 1972, she ran in the Democratic primary for Texas governor, and forced a close run-off vote with Dolph Briscoe. Soon afterwards in 1972, she was nominated as a Democratic vice-presidential candidate at the Democratic convention, in addition to her nomination as the chairperson of the National Women's Political Caucus. Farenthold ran in the Democratic primary for governor again in 1974, but lost decisively. From 1976 until 1980, she was the first woman president of Wells College, before coming back to Texas and opening a law practice. For the next three decades, Farenthold practiced law, taught at the University of Houston, and furthered her activism for the environment, as well as women's, minority's, gay and lesbian, and immigrant's rights. She currently lives in Houston and continues working towards these goals.

Francis Poulenc's Sonata for Horn, Trumpet and Trombone: A Structural Analysis Identifying Historical Significance, Form and Implications for Performance

Description: Research has been conducted on Francis Poulenc and his prominent 20th century sonata for brass instruments. Poulenc and members of the French compositional collaboration known as Les Six have all been subjects of research. Francis Poulenc's Sonata for Horn Trumpet and Trombone is a crucial piece in the development of brass chamber music during the 20th century. As one of the first works written for modern brass instruments, it demonstrates a highly crafted compositional style representative of Poulenc's early period. Research includes background and historical significance of the Sonata, analysis of form and compositional techniques, biographical information on Francis Poulenc and the members of Les Six and a section on implications for the performance of the work. This study is necessary due to the lack of research available for the piece especially considering its relevance to the development of brass chamber music. This study explores the compositional style of Francis Poulenc and his contribution to the brass ensemble repertoire.

Francis Thompson as a Myth-Maker

Description: The purpose of this paper is to establish that Francis Thompson, the English poet who lived from 1859 until 1907, is a myth-maker. In doing this, it will be necessary to define the term "myth-maker." The theme will then be developed by considering it in relation to the following topics: a brief resume of the events of his life having a direct bearing upon his mythic system, difficulties the student of his work must face, proof that he is a myth-maker of noteworthy significance, a consideration of the nature of his myth, a discussion of his most notable mythic values, and a special look at his mythic development of "The Hound of Heaven."

Franco-German Diplomatic Relations 1871-1939

Description: My purpose is to sketch briefly the diplomatic background of the existing relations between France and Germany from 1871 to 1939. I have told the story chronologically, because I believe that we must follow events as they unfold themselves if we are to understand why statesmen made their decisions. I have attempted to mass all the important facts that I could find on Franco-German Diplomatic Relations from 1871 to 1939 without self-interests or prejudices to either of the two nations. My intentions were to seek a general knowledge of the drift of Franco-German Diplomatic affairs during this period of seventy years.

Francophone Baptist Publications: Its Organization and Operation

Description: The problem of this study was to describe the operation and organization of Francophone Baptist Publications and to learn the publication needs of missionary personnel in the six countries served by the organization. Information for the study was gathered from Baptist history books, minutes from organizational meetings, questionnaires, and personal interviews with office and missionary personnel. The study revealed that although 47 per cent of those receiving questionnaires responded, only 28 per cent knew the materials and the organization sufficiently to evaluate them. This led to the conclusion that a lack of communication between the center and the missionaries exists and that the center should keep the market informed of materials available. The responses indicated that the present publications priorities do not reflect the real needs of the missionary personnel.

Frankel's Hypothesis of a Relation Between Phobic Symptoms and Hypnotic Responsiveness: Its Generalization to Agoraphobia

Description: The present study was designed to test Frankel and Orne's hypothesis that persons with a clinically significant phobia also show high susceptibility to hypnosis. The hypnotic susceptibility scores of 10 persons who sought treatment with hypnosis for agoraphobia were compared with the susceptibility scores of a control group of 20 persons having comparable motivation to succeed in hypnosis. The susceptibility measure was the Stanford Hypnotic Susceptibility Scale: Form C (SHSS:C, Weitzenhoffer & Hilgard, 1962). The groups were also compared on: a) the Archaic Involvement Measure (AIM; Nash, 1984); b) the Field Depth Inventory (FDI; Field, 1965); and c) the Tellegen Absorption Scale (TAS; Tellegen & Atkinson, 1974). No significant differences were found between the groups on the dependent measures. Factors which qualify the results are discussed.

Franz Liszt: (1811-1886): The Two Episodes from Lenau's Faust as a Unified Work

Description: Franz Liszt composed his Two Episodes from Lenau's Faust between 1856 and 1861. The composer intended to portray two emotionally contrasting scenes from Lenau's Faust in a set for orchestra, the first being The Night Procession and the second The Dance in the Village Inn. Liszt created a duet version of the orchestral set, and also a solo piano version of The Dance in the Village Inn, known as the Mephisto Waltz No. 1. The set was not performed together due to the immense popularity of The Dance in the Village Inn but also due to an unfortunate publication history resulting in the pieces being published separately by Schuberth publishers, published years apart from each other. As a result The Night Procession is largely forgotten today and The Dance in the Village Inn is interpreted as a single work outside of its context in a set. In this dissertation the works are examined from within its context in a set. Background information includes information on Liszt's student Robert Freund (1852-1936), and a solo piano transcription of the orchestral alternative ending to The Dance in the Village Inn. A comparison between Liszt's orchestral, solo and duet versions of the Mephisto Waltz No. 1 and the Liszt-Busoni Mephisto Waltz No. 1 is also made.

Free Association as a Mnemonic Device for Retention in Younger/Older People

Description: The purpose of this study was to determine whether and to what extent free association following exposure to written material would affect the memory of that material, and whether the effect upon memory would vary with age of the subject. A test of learning (immediate retention) resulted in a significant difference in performance between young and old women--the older learning less. Free association was not found to be significant as a mnemonic aid to either age group, and was compared with characteristics of other more common mnemonics. Suggestions for additional research are discussed.

Free Radical Chemistries at the Surface of Electronic Materials

Description: The focus of the following research was to (1) understand the chemistry involved in nitriding an organosilicate glass substrate prior to tantalum deposition, as well as the effect nitrogen incorporation plays on subsequent tantalum deposition and (2) the reduction of a native oxide, the removal of surface contaminants, and the etching of a HgCdTe surface utilizing atomic hydrogen. These studies were investigated utilizing XPS, TEM and AFM. XPS data show that bombardment of an OSG substrate with NH3 and Ar ions results in the removal of carbon species and the incorporation of nitrogen into the surface. Tantalum deposition onto a nitrided OSG surface results in the initial formation of tantalum nitride with continued deposition resulting in the formation of tantalum. This process is a direct method for forming a thin TaN/Ta bilayer for use in micro- and nanoelectronic devices. Exposure to atomic hydrogen is shown to increase the surface roughness of both air exposed and etched samples. XPS results indicate that atomic hydrogen reduces tellurium oxide observed on air exposed samples via first-order kinetics. The removal of surface contaminants is an important step prior to continued device fabrication for optimum device performance. It is shown here that atomic hydrogen effectively removes adsorbed chlorine from the HgCdTe surface.
