This dissertation is a performance guide for the euphonium solos Pearls I and Pearls II, written by Roland Szentpali. This performance guide allows performers to better understand the jazz styles within each movement and provides them with a resource for performing these particular pieces as well as other jazz influenced pieces. This performance guide is specific to euphonium repertoire and written for euphonium performers and educators. This is also a resource for a solo work in the repertoire that is performed regularly as well as a new work that will soon be published. A brief history of the development of euphonium repertoire and the influence of jazz is provided. The performance guide analyzes each movement and provides insight to extended techniques, common performance problems, errata, and jazz styles that each movement is based on. The guide also provides several suggestions for interpretation and for performance preparation. Illustrations from the scores have been provided for each example.

Lowell Liebermann, born in New York City in 1961, is one of America's most distinguished living composers. In addition, he often conducts and performs as pianist in his own works. His musical language is unique and unmistakably rooted in the grand tradition of Western music; however, his style combines old and new, simple and complex, emotional and intellectual aspects. It combines tuneful, catchy melodies with a rich harmonic language, all framed by a strong formal design. This study begins with presenting primary information on this concerto excerpted from an interview with Lowell Liebermann. This interview served as a reference for subsequent sections, and a transcript of the interview is appended to the end of this study. In the third chapter, the musical language of the composer is discussed. Chapters four and five constitute the main body of this dissertation. The goal of these two chapters is to understand the basic three-pitch motive of the work, to demonstrate how it operates at various levels, and to see how the raw material corresponds at a larger structure level. It is the author's hope that this study will guide performers to better understand Liebermann's Concerto No. 1 for Piano and Orchestra, Opus 12.

This dissertation examines the role of noise in shaping the form of several recent musical compositions. This study demonstrates how the contrast of noisy sounds and harmonic sounds can impact the structure of compositions. Depending on context, however, the specific use and function of noise can vary substantially from one work to the next. The first portion of this paper describes methods for quantifying noise content using FFT analysis procedures. A number of tests on instrumental and synthetic sound sources are described in order to demonstrate how the analysis system may react to certain sounds. The second part of this document consists of several analyses of whole musical works. Works for acoustic instruments are examined first, followed by works for electronic media. During these analyses, it becomes clear that while the use of noise in each work is based largely upon context, some common patterns do exist across different works. The final portion of the paper examines an original work which was written with the function of noise specifically in mind. The original work is put through the same analysis procedures as works seen earlier in the paper, and some conclusions are drawn regarding both the possibilities and limitations of …

Early interactions between parents and infants are thought to be critical of later development. In particular joint attention has been an area of research and investigations. This study sought to measure joint attention behaviors in infants from 5 to 33 weeks of age under naturalistic conditions: in the home with the mother as the interaction partner given no instructions. Videotapes of the infant-parent interactions were observed and data were collected on behaviors related to joint attention. Given observations occur at younger ages than other studies considered, engagement data results indicate increasing trends for 3 of the 5 infants observed while the direction of infant gaze results indicate patterns consistent with descriptions currently in the literature. Parent behavior data indicate high levels of support in engaging infant attention. Furthering an understanding of joint attention by observing at earlier ages in infant development may be useful in informing teaching programs for infants who have not developed joint attention skills.

Disney animation represents a powerful source of economic and cultural production. However, following the death of Walt Disney, the animation division found itself struggling to survive. It was not until the 1989 release of the hugely successful animated film The Little Mermaid that Disney would reclaim its domination among children's cultural producers. Additionally, The Little Mermaid inaugurated a shift in Disney's portrayals of gender as the company replaced the docile passive princess characteristic of its previous animated films with a physically active and strong willed ambitious heroine. Grounded in an understanding of Disney's cultural significance as dominant storyteller, the present study explores gender in The Little Mermaid by means of narrative performativity. Specifically, I analyze the film's songs "Part of Your World," "Under the Sea," and "Poor Unfortunate Souls" as metonymic narrative performances of gender that are (1) embodied, (2) materially situated, (3) discursively embedded and (4) capable of legitimating and critiquing existing power relations.

This study was conducted to analyze the performance differences between alternative education campuses in Texas that used teacher-directed strategies and those that used self-directed strategies. The study was also conducted to inform educators of the results these two strategies had achieved with at-risk students during the three years of 2006-2008. The study used the results from the Texas Assessment of Knowledge and Skills test as reported in the AEIS annual reports from the Texas Education Agency. Alternative education schools were grouped according to the strategy used to educate at-risk students. The results of the statistical tests showed the two strategies had similar performance results and there was no statistical difference between the two. The results offered several implications concerning the ability of at-risk students to achieve in alternative education schools including possible reasons why students who were previously unsuccessful became successful in alternative settings. The report also addressed the number of students who continued to be unsuccessful even when placed on an alternative education campus. Possible reasons for this continued inability to succeed are discussed. Recommendations for further research were listed at the conclusion of the study.

Professors in mass communications departments of higher education institutions continue to search for the best way to prepare graduates for the ever-changing world of print, broadcast, and online media. Business administration theories have long been used in other areas, including education. While some application of strategic planning has been documented with regards to education, there is not much to reference in this area. The study investigated the use of strategic planning in developing a course of action for curriculum convergence in mass communication programs. The study used a purposive sample to determine if administrators are utilizing this method as a part of curriculum convergence. The results indicated a use of this method among institutions involved in curriculum convergence.

Hungarian pianist, composer, conductor, teacher and administrator, Ernst von Dohnányi (Ernö Dohnányi in Hungarian), was considered one of the most versatile musicians and the first architect of Hungary's musical culture in the late nineteenth and early twentieth-century. Dohnányi composed the Four Rhapsodies, op. 11, between 1902 and 1903, and among his many piano compositions, op. 11 are regarded as some of his most substantial works. Without directly imitating the earlier works of Liszt and Brahms, Dohnányi contributed to the rhapsody tradition with op. 11 by using his own unique stylistic compositional elements in the textural and formal structure. Texture and form are the most indicative characteristics of his rhapsodic language because of the improvisational nature that permeates his compositional style in the rhapsodies. In this dissertation the works are examined from within its textural and formal structure. Within texture, rhythm and accompanimental figurations are examined. Each rhapsody's structural organization, including references to eighteenth-century forms, and the cyclical elements in the work is analyzed. Background information on Dohnányi and a brief history of the rhapsody in the 19th century is also included.

The preface to this collection "Dust Clouding: Ambiguity and the Poetic Image," highlights the ways in which poets such as W.S Merwin and Donald Revell use ambiguity and the poetic image to strengthen their poems and encourage equality between reader and writer. Hand Amputees have an Altered Perception of Images at Arm's Length is a collection of poems and poem like adventures.

Male or female, young or old, the characters of this collection inhabit a liminal space of trauma and social dislocation in which elements of the real and fabulous coexist in equal measure. The ghosts that populate the stories are as much the ghosts of the living, as they are the ghosts of the dead. They represent individual conscience and an inescapable connection to the past.

This thesis imparts the outcomes of a seven-week long quasi-experimental study that explored whether or not L2 learners who received intensive and highly focused indirect feedback on one type of treatable error - either the third person singular -s, plural endings -s, or definite article the - eventually become more accurate in the post-test as compared to a control group that did not. The paired-samples t-test comparing the pre-test and post-test scores of both groups demonstrates that the experimental group did no better than the control group after they received indirect corrective feedback. The independent samples t-test measuring the experimental and control group's accuracy shows no significant difference between the two groups. Effect sizes calculated, however, do indicate that, had the sample sizes been bigger, both groups would have eventually become more accurate in the errors targeted, although this would not have been because of the indirect feedback.

Post-civil war democratization is a critical element of building sustainable peace in the post-civil war states. At the same time, studies of democratic transition and survival suggest that the post-civil war environment is not hospitable to either the transition to or survival of democracy. The post-civil war environment is contentious. Former protagonists are fearful about their security and at the same time they want to protect their political and economic interests. The central argument of this study is that former rivals can agree to a transition toward democracy to the extent that a stable balance of power exists between the government and rebel groups, a balance that eliminates the sort of security dilemma that would encourage one or both to resume armed conflict. And the balance should ensure access to political power and economic resources. This study identifies factors that contribute to the establishment of such a balance of power between former protagonists and factors that affects its stability. These factors should affect the decision of former protagonists on whether or not they can achieve their political and economic interests if they agree to a transition toward democracy once civil war ends. Factors that are conducive to a transition toward …

The major advantages of radio frequency identification (RFID) technology over barcodes are that the RFID-tagged objects do not require to be in line-of-sight with the reader for their identification and multiple objects can be read simultaneously. But when multiple objects are read simultaneously there is always a problem of collision which reduces the efficiency of the system. This thesis presents a comprehensive study of the dynamic framed slotted ALOHA (DFSA)-based anti-collision multi-tag identification algorithms for passive RFID system. Performance of various DFSA algorithms is compared through extensive simulation results. In addition, a number of simple performance improvement techniques have also been investigated in this thesis, including improved estimation techniques for the number of tags in each read cycle and a low-complexity heuristic stopping criterion that can be easily implemented in the practical system.

While the relationship between academic variables and admission into medical school has been well documented, the relationship between socioeconomic background and admission has not been extensively examined. In 2001, the Texas Legislature passed HB 1641, which allowed for the use of socioeconomic variables in the admission of graduate and professional school students. Additionally, the Grutter v. Bollinger decision in 2003 removed a prohibition on the use of race or ethnicity in the admission of students in the state of Texas. The study examined the role medical school admissions selectivity as it relates to the socioeconomic background during a race neutral admissions cycle in 2005 and a race sensitive admissions cycle in 2006. The results of data analysis found that in a race neutral admissions cycle socioeconomic background was a significant factor in the admission of applicants to medical school. However, it was not a significant factor for applicants from underrepresented minority groups. The analysis also found that socioeconomic background was a significant factor in the admission of applicants to medical school in a race sensitive admissions cycle as well. Finally, the study found that variances in selectivity led to differences in the socioeconomic makeup of entering students across different medical …

This dissertation deals with three topics in descriptive set theory. First, the order topology is a natural topology on ordinals. In Chapter 2, a complete classification of order topologies on ordinals up to Borel isomorphism is given, answering a question of Benedikt Löwe. Second, a map between separable metrizable spaces X and Y preserves complete metrizability if Y is completely metrizable whenever X is; the map is resolvable if the image of every open (closed) set in X is resolvable in Y. In Chapter 3, it is proven that resolvable maps preserve complete metrizability, generalizing results of Sierpiński, Vainštein, and Ostrovsky. Third, an equivalence relation on a Polish space has the Laczkovich-Komjáth property if the following holds: for every sequence of analytic sets such that the limit superior along any infinite set of indices meets uncountably many equivalence classes, there is an infinite subsequence such that the intersection of these sets contains a perfect set of pairwise inequivalent elements. In Chapter 4, it is shown that every coanalytic equivalence relation has the Laczkovich-Komjáth property, extending a theorem of Balcerzak and Głąb.

Frederic Woodman Root was a vocal pedagogue and writer of the late nineteenth century. He wrote over eighteen books on vocal pedagogy, and numerous articles on singing. Since his death, most of his works have fallen into obscurity. The purpose of this document was to codify the vocal pedagogy of Frederic Woodman Root, discussing his particularly thorough methodology, and to bring his methods back into the public eye. His method is broken down into the various components of basic musicianship, the General Principle, the Three Vowel Forms, registers, breathing, and agility. Examples from Root's exercises are included and discussed.

Because racism remains a significant issue in society, and many victims of racism do not speak up for themselves when faced with racism, it is important to explore how witnesses to racist events may react and intervene upon observing racism toward others. Thus, the current study explored how participants (bystanders) reacted verbally to racist comments made by a confederate during a partner activity, as well as how participants discussed their reactions in post-interviews. Forty college students participated in the study, and three of the participants verbally intervened upon hearing the racist statements. Ajzen's theory of planned behavior was utilized as a framework, and examination of the results indicated that components of the theory as well as social constructions of racism and appropriateness of intervention behaviors affect intervention outcomes. Theoretical, methodological, and practical implications, as well as suggestions for future research are included.

The history of the saxophone and its development as a performance medium in Japan is short when compared with other European countries and the United States. In this short history, the saxophone performance level in Japan has increased dramatically. At the same time, compositions for the saxophone by Japanese composers have gained more popularity in the world as can be seen in the program of the World Saxophone Congress and the North American Saxophone Alliance conference. The saxophone history in Japan, including contributions of Arata Sakaguchi (1910-1997), Ryo Noda (b.1948), and Nobuya Sugawa (b.1961), is discussed in order to understand the increase of performances of pieces for saxophone by Japanese composers. The success of many original compositions, especially those that incorporate the synthesis of Eastern and Western music, is another significant element examined in this document. Yoshimatsu approaches music for classical saxophone as a new genre. He seeks all possible sounds that the saxophone can create - beautiful tone to "noise like" - in his compositions. The blending of other musical styles in one piece is one of Yoshimatsu's compositional styles, which can be observed in Fuzzy Bird Sonata; however, he does not limit himself to a single style. This …

Macroinvertebrates associated with the aquatic plant, water stargrass (Heteranthera dubia), were sampled from 12 waterbodies in four regions of the United States from June to August 2005. Taxa richness, evenness, and diversity were lowest in the Lower Midwest (LMW) region, and higher in Northern sites, especially the Upper Midwest (UMW), and Northeast (NE). While relative abundance varied from site to site and region to region, utilization of the plant by functional groups remained fairly constant. Collector-gatherers consistently comprised the largest portion of invertebrates sampled. The shredder/ herbivore functional group comprised an average of 17 % of total groups. Through an exhaustive literature review, it was found that shredder/ herbivores of water stargrass have not been reported in the literature. Because of this, the herbivore group was analyzed separately and consisted of 2,383 specimens representing 23 species. The most common groups were Rhopalosiphum sp., Nectopsyche spp. and chironomids. No differences were found in herbivore diversity or evenness between sampling regions, but species richness was significantly different.

Proteomic techniques were used to analyze the protein profile of earthworm, Lumbricus terrestris, coelomic fluid collected by either whole body dissection method or the coelomic cavity puncture method. Data demonstrated that collection of coelomic fluid using the coelomic cavity puncture method protocol resulted in a 32% reduction, 377 +/- 4.5 vs 253+/- 19.9 (p=0.0007), in the number of individual proteins. It was determined that the coelomic cavity puncture method yielded a "cleaner" preparation, one less contaminated with extraneous proteins from intestinal tissue, gut contents, and body wall materials. This protocol was used in all later studies. The same proteomic techniques were used to evaluate the effects that exposure to Cu (1.0 μg/cm2) as CuSO4 had on the earthworm coelomic fluid profile. Comparison of protein profile from exposed earthworms demonstrated a significant reduction in the number of proteins expressed (184 ± 2.64 vs 253 ±19.9 p=0.0192) when compared to control organisms. Cu exposure also resulted in a modulation of the protein profile with treated earthworms expressing 47 new proteins that were not identified in unexposed worm coelomic fluid. Additionally, 116 proteins found in coelomic fluid collected from normal worms were absent in Cu exposed organisms. Finally, 137 proteins were conserved or …

For an introductory macroeconomics course, the discussion of historical relevance helps foster important learning connections. By comparing the Great Depression to the 2008-2009 recession, a macroeconomics instructor can provide students with connections to history. This paper discusses the major causes of each recession, major fiscal policy and monetary policy decisions of both recessions, and the respective relevance in teaching the relationship of each policy to gross domestic product. The teaching points addressed in this paper are directed towards an introductory college-level macroeconomics course, incorporating a variety of theories from historical and economic writers and data from government and central bank sources. A lesson plan is included in an appendix to assist the instructor in implementing the material.

The focus of this study is to provide a clear understanding of Vaughan Williams' Violin Concerto in D Minor. In terms of form and compositional technique, this concerto is particularly challenging, because of Vaughan Williams' use of rhythmic motives and modes. This study is undertaken through an analysis. For a better understanding, a historical background, including overall form of each movement and key relationships, is explored and discussed. Then, Vaughan Williams' use of a ritornello-like motive, melody and modality as unifying elements is also identified and examined. In identifying the major features of Vaughan Williams' compositional style of this violin concerto, musicians will be able to understand better his unique musical expression. This study may serve as an introduction to the music of Vaughan Williams for musicians and society worldwide. It is hoped that it will motivate all violinists to perform this concerto more frequently.

Alpine zooplankton are exposed to a variety of stressors in their natural environment including ultraviolet radiation. Physiological coping mechanisms such as the accumulation of photoprotective compounds provide these zooplankton protection from many of these stressors. Elevated levels of carotenoid compounds such as astaxanthin have been shown to help zooplankton survive longer when exposed to ultraviolet radiation presumably due to the strong antioxidant properties of carotenoid compounds. This antioxidant capacity is important because it may ameliorate natural and anthropogenic stressor-induced oxidative stress. While previous researchers have shown carotenoid compounds impart increased resistance to ultraviolet radiation in populations of zooplankton, little work has focused on the toxicological implications of PAH induced phototoxicity on zooplankton containing high levels of carotenoid compounds. This thesis discusses research studying the role that carotenoid compounds play in reducing PAH induced phototoxicity. By sampling different lakes at elevations ranging from 9,500' to 12,700' in the front range of the Colorado Rocky Mountains, copepod populations containing different levels of carotenoid compounds were obtained. These populations were then challenged with fluoranthene and ultraviolet radiation. Results discussed include differences in survival and levels of lipid peroxidation among populations exhibiting different levels of carotenoid compounds, and the toxicological and ecological implications of …

The analysis of computer music presents new challenges to the field of music theory. This study examines the fixed media composition Phoné by John Chowning from its aesthetic perspective, compositional theory and computer sound synthesis techniques. Fast Fourier Transform analyses are used to create spectrograms. The findings from the spectrograms are juxtaposed with compositional philosophies of John Chowning, Jean-Claude Risset, Pierre Schaeffer and Arnold Schoenberg and the techniques are represented via PureData patches.
