Michael Daugherty has created his niche in the music world by composing works inspired by icons of American popular culture. Red Cape Tango is the final movement of his Metropolis Symphony, a work inspired by the life and times of the comic book character Superman. This movement in particular deals with the death of the superhero through the use of musical elements, most notably the Latin Sequence of the Mass for the Dead, Dies irae. Daugherty's ingenuity in blending profoundly dark subjects with humor is particularly evident in this work. Death is personified as a temptress and lures Superman through the power of a seductive tango. This study concentrates on Daugherty's compositional style and its impact in musical circles. A transcription for wind orchestra was created by another composer/conductor precisely because of the need to bring such an important work to another medium, thus making it accessible to a wider audience. In addition, this study looks at the changes in instrumentation necessary to create a second, equally formidable version of the work.

The developments of nuclear medicine lead to an increasing demand for the production of radioisotopes with suitable nuclear and chemical properties. Furthermore, from the literature it is evident that the production of radioisotopes using charged-particle accelerators instead of nuclear reactors is gaining increasing popularity. The main advantages of producing medical isotopes with accelerators are carrier free radionuclides of short lived isotopes, improved handling, reduction of the radioactive waste, and lower cost of isotope fabrication. Proton-rich isotopes are the result of nuclear interactions between enriched stable isotopes and energetic protons. An interesting observation is that during the production of proton-rich isotopes, fast and intermediately fast neutrons from nuclear reactions such as (p,xn) are also produced as a by-product in the nuclear reactions. This observation suggests that it is perhaps possible to use these neutrons to activate secondary targets for the production of neutron-rich isotopes. The study of secondary radioisotope production with fast neutrons from (p,xn) reactions using a particle accelerator is the main goal of the research in this thesis.

Thomas Lovell Beddoes' female dramatic characters are, for the most part, objectified and static, but these passive women perform a crucial narrative and thematic function in the plays. Alongside the destructive activity of the male characters, they dramatize masculine-feminine unions as idealized and contrived and, thus, unstable. Desire, power and influence, as well as the constrictive aspects of physicality, all become gendered concepts in Beddoes' plays, and socially normative relationships between men and women, including heterosexual courtship and marriage, are scrutinized and found wanting. In The Brides' Tragedy, Floribel and Olivia, the eponymous brides, represent archetypes of innocence, purity, and Romantic nature. Their bridegroom, Hesperus, embodies Romantic masculinity, desiring the feminine and aspiring to androgyny, but ultimately unable to relinquish masculine power. The consequences of Hesperus' attempts to unite with the feminine other are the destruction of that other and of himself, with no hope for the spiritual union in death that the Romantic Hesperus espouses as his ultimate desire. Death's Jest-Book expands upon the theme of male-female incompatibility, presenting heterosexual relationships in the context of triangulated desire. The erotic triangles created by Melveric, Sibylla, and Wolfram and Athulf, Amala, and Adalmar are inherently unstable, because they depend upon the …

The main objective of this document is to explore the life and spiritual convictions of composer Peter Lieberson, and the creation of his Piano Concerto. Lieberson is a sought after composer who has won many awards and commissions. His works have been premiered and performed by some of the best musical artists of the late twentieth- and early twenty-first-century, such as Peter Serkin, Emmanuel Ax, Yo-Yo Ma, and Pierre Boulez. This study is divided into six chapters. After the Introduction, a biographical summary of Peter Lieberson's life, his spiritual beliefs and compositional style is presented. Chapter II contains background information on the Piano Concerto, along with biographical sketches of Peter Serkin, for whom the work was written, and Seiji Ozawa, music director of the Boston Symphony Orchestra and conductor of both the premier performance and Serkin's recording of the piece. Chapter III is a selective survey of the compositional techniques used in Lieberson's Concerto, in terms of the application of twelve-tone theory and the resulting octatonic, pentatonic, and whole-tone scales. Chapter IV introduces a general overview of the influence of Buddhism as a source of inspiration in the Piano Concerto. Chapter V examines aspects of performance practice issues. Chapter VI …

For the past quarter century, the public has been educated and warned about the dangers of smoking, and both smokers and health researchers have been in search of cost-effective, smoking cessation programs that will lead to long-term cessation. This study used a randomized experimental design to investigate the effectiveness of adding Web-based support materials to a nationally sponsored self-help smoking intervention. There was no significant increase in abstinence rates nor progression through the stages of change by those participants who had access to the Web site. However, there were some overall significant trends that suggested these self-help interventions were successful at decreasing daily rates of smoking and nicotine dependency, as well as tended to encourage repeated quit attempts. Although Web-based supports did not appear to increase the effectiveness of the nationally sponsored self-help intervention, this study demonstrated overall 12 week follow-up abstinence rates of 30-32%--greater than what might be expected, given average success rates of other self-help interventions. This study also supports the notion that women may face additional barriers to smoking cessation. Limitations and implications for future research are discussed.

The purpose of this study was twofold: to determine the construct validities of comparable AD/HD instruments that were developed according to our current, DSM-IV classification system for AD/HD; and to identify potential +neurocognitive and socioemotional markers for AD/HD. The sample consisted of 145 children ages 8 to 11 years of age who were diagnosed with Attention Deficit Hyperactivity Disorder (AD/HD), or Central Auditory Processing Disorder (CAPD). Children were administered a battery of neurocognitive tests and completed a self-report measure of personality. Parents completed several, AD/HD instruments pertaining to their children. The AD/HD instruments used in this study were the Attention Deficit Disorder Evaluation Scale-Home Version (ADDES), Attention Deficit Hyperactivity Disorder Test (ADHDT), and the Attention Problems and Hyperactivity scales from the BASC-Monitor (BASC-M). Of interest was how each AD/HD instrument compared to the DSM-IV, particularly in terms of the cross-consistency of AD/HD subtype classifications. The findings showed that the AD/HD instruments classified participants differently from the initial, DSM-IV entry diagnosis. Rates of agreement were better for some of the AD/HD instruments than for others yet there was little overall consistency. The neurocognitive measures used in the study were the Cognitive Assessment System-Basic Battery scales. The socioemotional measures used in the …

Constructed wetlands are considered an inefficient technology for long-term phosphorus (P) removal. The P retention effectiveness of subsurface wetlands can be improved by using appropriate substrates. The objectives of this study were to: (i) use sorption isotherms to estimate the P sorption capacity of the two materials, masonry sand and light weight expanded shale; (ii) describe dissolved P removal in small (2.7 m3) subsurface flow wetlands; (iii) quantify the forms of P retained by the substrates in the pilot cells; and (iv) use resulting data to assess the technical and economic feasibility of the most promising system to remove P. The P sorption capacity of masonry sand and expanded shale, as determined with Langmuir isotherms, was 60 mg/kg and 971 mg/kg respectively. In the pilot cells receiving secondarily treated wastewater, cells containing expanded shale retained a greater proportion of the incoming P (50.8 percent) than cells containing masonry sand (14.5 percent). After a year of operation, samples were analyzed for total P (TP) and total inorganic P (TIP). Subsamples were fractionated into labile-P, Fe+Al-bound P, humic-P, Ca+Mg-bound P, and residual-P. Means and standard deviations of TP retained by the expanded shale and masonry sand were 349 + 169 and 11.9 …

The musical developments of the 20th century have expanded the role of the accompanist. As the compositional output of our time increases, and the opportunity to perform as soloist with an orchestra diminishes, piano reductions of an orchestral score are becoming the most frequent vehicle for concerto performances of twentieth and twenty-first century instrumental literature. While the current state of research provides solid support to many accompanists, it is in the area of instrumental accompanying, especially with regard to the challenges of playing a reduction of an orchestral score with an instrumental soloist, that the lack of discourse becomes strikingly evident. It is the goal of this study to provide the instrumental accompanist with concrete, practical approaches and considerations in order to perform an orchestral reduction in a manner consistent with the integrity of the score. Problems such as identifying the represented orchestral instruments, delineating importance of musical lines, and basic uses and misuses of pedal, articulation, and rubato are discussed. The pianist is led through ways of deciphering and negotiating specific passages, in order to guide the accompanist through the possible pitfalls and challenges unique to many orchestral reductions. By focusing on twentieth century reductions, providing examples of problems …

The compositions of Fisher Aubrey Tull are widely performed and many have become standard repertoire. Tull's compositions encompass a multiplicity of performance media including works for orchestra, chorus, symphonic band, jazz band, brass choir, and solo and chamber works. Tull's compositional output for the trumpet is prolific and is acknowledged to be music of high quality. An examination of Trumpet and Brass Programs, compiled and published annually by the International Trumpet Guild, shows Tull's solo and ensemble works for trumpet to be frequently performed. Furthermore, his compositions for trumpet have been performed and recorded by internationally acclaimed artists including Vincent DiMartino, Terry Everson, Håkan Hardenberger, Anthony Plog, Carl "Doc" Severinsen and Allen Vizzutti.This study investigates Fisher Tull's eight solo works for trumpet, which include: Vignette for Trumpet and Piano (1954); Concerto No. 1 for Trumpet and Orchestra (1964); Concerto No. 2 for Trumpet and Band (1974); Three Bagatelles for Trumpet and Piano (1975); Eight Profiles for Solo Trumpet (1978); Rhapsody for Trumpet and Band (1980); Sonata for Trumpet and Piano (1986); and Chromutations for Solo Trumpet (1988). Histories of each composition are chronicled. An analysis of formal organization and significant style features examines musical structure, harmonic language, rhythmic character, instrumentation, …

There is a lack of clarity in the current literature in how potential etiological factors interact and result in disordered eating. The purpose of this study was to examine an expanded model of Personality, Social Support, Appraisal/Coping Processes, Abuse History, Internalization of Sociocultural Standards, Psychological Disturbances, and Body Disparagement in the development of disordered eating. The current model was evaluated using 276 women in their transition to college, a time period highly associated with symptoms believed to increase a woman's risk for the development of disordered eating including perceived difficulty coping, weight gain, and negative affect. Structural equation modeling was used to allow simultaneous examination of the causal relationships between the factors. Structural analyses confirmed that college women with previous stressful experiences appraised the adjustment to college as more stressful and reported feeling less able to cope with the transition. Those women who identified the transition as overwhelming were also aware of increased negative mood and psychological states since beginning the school semester. Further, women with previous traumatic sexual experiences appeared to be at additional risk for increased negative affective symptoms. The resulting model confirmed that those women who experience negative mood states and those that endorse strong internalization of …

A biological monitoring tool to assess water quality using bivalve gape behavior was developed and demonstrated. The purpose of this work was to develop methodologies for screening water quality appropriate to the goals of the watershed paradigm. A model of bivalve gape behavior based on prediction of behavior using autoregressive techniques was the foundation of the bivalve biomonitoring system. Current technology was used in developing the system to provide bivalve gape state data in a continuous real-time manner. A laboratory version of the system, including data collection and analysis hardware and software, was developed for use as a toxicological assay for determination of effective concentrations of toxicant(s) or other types of stress on bivalve gape behavior. Corbicula fluminea was monitored and challenged with copper, zinc, and chlorpyrifos using the system. Effective concentrations of 176±23µg/L copper, 768±412µg/L zinc, and 68µg/L chlorpyrifos were observed using a natural water with high dissolved organic carbon concentrations. A rugged field version of the bivalve biomonitoring system was developed and deployed in two locations. The field systems were fitted with a photovoltaic array, a single board computer, and a CDPD telemetry modem for robust remote operation. Data were telemetered at a time relevant rate of once …

The purpose of this study was to determine if there was a relationship between training in learning style adaptation and successful completion of community college courses. The rationale for conducting this study was based on the need for students to learn how to adapt their learning style in order to more effectively learn in any situation. It is also important that community colleges implement strategies that assist in student retention. The learning styles of entry-level community college students were measured using Kolb's Learning Style Inventory Version 3. Students enrolled in entry-level college courses at a small North Texas community college were studied. The Chi-square Test of Independence with a 2 x 2 design was employed. Findings indicated that there was no statistically significant difference in the relationship between students receiving training in learning styles adaptation and successful completion of entry-level college courses, and that students who attended a learning styles training session and those who did not attend a learning styles training session had an equal chance of succeeding in entry-level community college courses. Findings also indicated that students with Accommodating and Assimilating learning styles are less likely to successfully complete an entry-level college course than are students with Diverging …

The thermochemistry of several species, and the kinetics of various H atom radical reactions relevant to atmospheric and combustion chemistry were investigated using ab initio theoretical techniques and the flash photolysis / resonance fluorescence technique. Using ab initio quantum mechanical calculations up to the G3 level of theory, the C-H bond strengths of several alkanes were calculated. The bond strengths were calculated using two working reactions. From the results, it is apparent that the bond strengths decrease as methyl groups are added to the central carbon. The results are in good agreement with recent experimental halogenation kinetic studies. Hydrogen bond strengths with sulfur and oxygen were studied via CCSD(T) theory, together with extrapolation to the complete basis set limit. The results for the bond dissociation energies (ground state at 0 K, units: kJ mol-1) are: S-H = 349.9, S-D = 354.7, HS-H = 376.2, DS-D = 383.4, and HO-H = 492.6. These data compare well with experimental literature. The rate constants for the isotopic reactions of H + H2S, D + H2S, H + D2S, and D + D2S are studied at the QCISD(T)/6-311+G(3df,2p) level of theory. The contributions of the exchange reaction versus abstraction are examined through transition state …

The purpose of this study determined whether use of student random drug testing provided an effective means to reduce drug usage by secondary school students. The participants included 50,214 7th through 12th grade students in 12 selected public schools. All school districts participated in the Texas School Survey of Substance Use in 1994, 1996, 1998, and 2000. The six districts in the experimental group used drug testing as a method of reducing drug usage among students. The six districts in the control group did not use drug testing. Although athletes and students involved in extracurricular activities remain the focus of random dug testing, this research focused on an entire school population to determine whether drug testing only a select group of students reduced reported drug usage in the entire school. Two questions guided the research: First, does the use of random drug testing have an impact on student drug usage? Second, does the year of implementation of random drug testing have an impact on students' self-reported drug usage? The findings for each research question were categorized according to nine illegal drugs. The researcher used a one-way repeated measures factorial design. The data were analyzed via the univariate (split-plot) 2 x …

A study was conducted to evaluate the sorption characteristics of six disinfection byproducts (DBPs) on four sorbents. To investigate sorption of volatile organic compounds (VOCs), specially designed experimental batch and continuous flow modules were developed. The investigated compounds included: chloroform, 1,2-dichloroethane (DCE), trichloroethylene (TCE), bromodichloromethane (BDCM), methyl tertiary butyl ether (MTBE), bromate and bromide ions. Sorbents used included light weight aggregate (LWA), an inorganic porous material with unique surface characteristics, Amberlite® XAD-16, a weakly basic anion exchange resin, Amberjet®, a strongly basic anion exchange resin, and granular activated carbon (GAC). Batch experiments were conducted on spiked Milli-Q® and lake water matrices. Results indicate considerable sorption of TCE (68.9%), slight sorption of bromate ions (19%) and no appreciable sorption for the other test compounds on LWA. The sorption of TCE increased to 75.3% in experiments utilizing smaller LWA particle size. LWA could be a viable medium for removal of TCE from contaminated surface or groundwater sites. Amberlite® was found unsuitable for use due to its physical characteristics, and its inability to efficiently remove any of the test compounds. Amberjet® showed an excellent ability to remove the inorganic anions (>99%), and BDCM (96.9%) from aqueous solutions but with considerable elevation of pH. …

The preparation of layered double hydroxides via co-precipitation of a divalent/trivalent metal solution against a base results in 1 mm LDH particles with a disorganized metal lattice. Research was performed to address these morphological issues using techniques such as Ostwald ripening and precipitation via aluminate. Another interesting issue in layered double hydroxide materials is the uptake and orientation of anions into the interlayer. Questions about iron cyanide interlayer anions have been posed. Fourier transform infared spectroscopy and powder x-ray diffraction have been used to investigate these topics. It was found that factors such as orientation, anion charge, and anion structure depended on the divalent/trivalent metal ratio of the hydroxide layer and reactivity time. The cyanide self-addition reaction is an important reaction of classical prebiotic chemistry. This reaction has been shown to give rise to amino acids, purines and pyrimidines. At cyanide concentrations similar to that expected on the early earth, hydrolysis to formamide rather than self-addition occurs. One theory to alleviate this side reaction is the use of minerals or clays that are thought to concentrate and catalyze prebiotics of interest. Layered double hydroxides have been studied as a catalyst for this reaction.

In this study of A Midsummer Night's Dream, The Merchant of Venice, and Measure for Measure I argue that the surface plots of these comedies point us to a philosophic understanding seldom discussed in either contemporary public discourse or in Shakespearean scholarship. The comedies usually involve questions arising from the conflict between the enforcement of law (whether just or not) and the private longings (whether noble or base) of citizens whose yearnings for happiness tend to be sub- or even supra-political. No regime, it appears, is able to respond to the whole variety of circumstances that it may be called upon to judge. Even the best written laws meet with occasional exceptions and these ulterior instances must be judged by something other than a legal code. When these extra-legal instances do arise, political communities become aware of their reliance on a kind of political judgment that is usually unnoticed in the day-to-day affairs of public life. Further, it is evident that the characters who are able to exercise this political judgment, are the very characters whose presence averts a potentially tragic situation and makes a comedy possible. By presenting examples of how moral and political problems are dealt with by …

The procedural survey on sexual harassment procedures sent to 300 Texas principals had a response rate of 48.3 %. The mean score on the procedural survey for all 300 principals was 69.30 %. Eighteen research questions were addressed in detail in Chapter 4. Only five showed a significant correlation or effect size. Question 5 asked if there was a correlation between gender and the mean score of the survey instrument regarding sexual harassment procedures. The mean score of women was significantly higher than men. Question 6 asked if there was a correlation between the number of students in a school and the mean score of the survey instrument regarding sexual harassment procedures. This revealed that a significant correlation appeared between principals who worked at larger schools. Question 10 asked if there was a correlation between the location of the school, whether rural, urban, or metroplex and the mean score of the survey instrument. Principals of urban and metroplex schools scored significantly higher. Question 13 asked if there was a correlation between the hours of sexual harassment training attended in the last year and the mean score of the survey instrument regarding sexual harassment procedures. The results of this analysis revealed …

This dissertation asserts the British primacy in the deliberations of the League of Nations Council between the two world wars of the twentieth century. It maintains that it was British imperial policy rather than any other consideration that ultimately carried the day in these deliberations. Given, as examples of this paramountcy, are the discussions around the finalization of the borders of the new republic of Turkey, which was created following the collapse of the Ottoman Empire at the end of the First World War. These discussions focused on three areas, the Mosul Vilayet or the Turco-Iraqi frontier, the Maritza Delta, or the Turco-Greek frontier, and the Sanjak of Alexandretta or the Turco-Syrian frontier.

The scope of this study includes relevant background information on Peter Schat and his compositions and process, an explanation of the Tone Clock system and a detailed analysis of one of his compositions, the Etudes for Piano and Orchestra, Opus 39. The intent is to demonstrate how the Tone Clock naturally evolved from the practices of the Second Viennese School and how it relates to both new and existing modern music. The study is divided into five chapters. Chapter 1 presents a brief introduction to Peter Schat and the Tone Clock. Chapter 2 provides a more detailed biography of Peter Schat and traces the development and evolution of his compositional techniques, ultimately culminating in the Tone Clock. Chapter 3 provides a basic explanation of the Tone Clock itself, with demonstrations of various components through musical examples and illustrations. Chapter 4 is a detailed analysis of the Etudes for Piano and Orchestra, Opus. 39. Chapter 5 summarizes the results of the study, with special attention to the impact of the Tone Clock on performance from the perspective of the performer. The analysis of the Etudes was completed by using the Tone Clock as an analytical tool, aided by the composer's original …

This study uses teacher employment data provided by the State Board for Educator Certification to examine the similarities and differences between initial employment and attrition rates of teachers trained in three prevalent types of Texas teacher preparation programs; alternative certification programs (ACP), the centers for professional development of teachers (CPDT), and traditional certification programs (TCP). The population for the study includes all Texas teachers who completed training in these programs in 1995, 1996, and 1997. The study found that ACP participants gain employment as Texas public school teachers at a significantly higher rate than their CPDT and TCP trained peers in year-one after completion of their training. However, ACP completers experience higher attrition rates in each of the subsequent years investigated. The study concludes that the overall cumulative attrition rate of new teachers trained in these programs is not as pronounced as originally presumed, but that low production levels cannot keep up with the growing demand for new teachers. Teacher preparation program leaders must seek ways to recruit and train more teachers.

The purpose of this study was to develop profiles that described teachers with infrequent and frequent teacher-directed student use of the Internet for curricular purposes. Responses to the teachers' self-reported needs, beliefs, demographics, Internet skill levels, and other information were examined as the basis for the study. The study was descriptive in nature, utilized correlation and causal-comparative methods, and employed a convenience sample. The population consisted of 3,187 public school teachers from Nebraska and four service regions in upstate New York. Data related to the research questions were gathered using an online survey. After minimum access was determined, frequencies, percentages, t tests, and correlations were used to examine the data. Teachers with infrequent (<15 mins. /week) teacher-directed student use of the Internet comprised 63% of the sample. Teachers from elementary and high school levels were almost equally represented in the infrequent use group. The majority of the high school level teachers were assigned to language arts, mathematics or science courses. Teachers in the frequent (>. 90 mins. /week) use group were predominately (75%) high school level, with the majority teaching computer and business subjects. Significant differences were found between the use groups regarding beliefs about the Internet's effect on students …

The first diamond mine in North America was discovered in 1906 when John W. Huddleston found two diamonds on his farm just south of Murfreesboro in Pike County, Arkansas. Experts soon confirmed that the diamond-bearing formation on which Huddleston made his discovery was the second largest of its kind and represented 25 percent of all known diamond-bearing areas in the world. Discovery of the field generated nearly a half century of speculative activity by men trying to demonstrate and exploit its commercial viability. The field, however, lacked the necessary richness for successful commercial ventures, and mining was eventually replaced in the early 1950s by tourist attractions that operated successfully until 1972. At that time the State of Arkansas purchased the field and converted it to a state park. Thus this work tell the rich and complicated story of America'a once and only diamond field, analyzes the reasons for the repeated failures of efforts to make it commercially viable, and explains how it eventually succeeded as a tourist venture.

This dissertation provides a history of Spanish-Comanche relations during the era of Spanish Texas. The study is based on research in archival documents, some newly discovered. Chapter 1 presents an overview of events that brought both people to the land that Spaniards named Texas. The remaining chapters provide a detailed account of Spanish-Comanche interaction from first contact until the end of Spanish rule in 1821. Although it is generally written that Spaniards first met Comanches at San Antonio de Béxar in 1743, a careful examination of Spanish documents indicates that Spaniards heard rumors of Comanches in Texas in the 1740s, but their first meeting did not occur until the early 1750s. From that first encounter until the close of the Spanish era, Spanish authorities instituted a number of different policies in their efforts to coexist peacefully with the Comanche nation. The author explores each of those policies, how the Comanches reacted to those policies, and the impact of that diplomacy on both cultures. Spaniards and Comanches negotiated a peace treaty in 1785, and that treaty remained in effect, with varying degrees of success, for the duration of Spanish rule. Leaders on both sides were committed to maintaining that peace, although …
