The Significance of Dmitri Shostakovich's Piano Sonata Op.12

Description: The aspiration of this dissertation is to bring forth the significance of Shostakovich's Piano Sonata Op.12. This sonata is a hybrid of the German musical tradition, Russian Modernism, and Liszt's thematic transformation technique. It demonstrates Shostakovich's highly intellectual compositional skills influenced by the education that he received at St. Petersburg Conservatory as well as the exposure to modern music in the 1920s. This dissertation discusses composition techniques, such as the harmonic piers adapted from Alexander Scriabin, neighboring-tone technique, which involves the application of semitone cell throughout the piece, as well as the technique of thematic transformation borrowed from Liszt. These all come together by Shostakovich's design in the most controversial sonata form. The Piano Sonata Op.12 also sheds light on Shostakovich's early compositional style and proves its contribution to the evolution of sonata genre in the twentieth-century.

Perceived attributes of diffusion of innovation theory as predictors of Internet adoption among faculty members of Imam Mohammed Bin Saud University.

Description: The Internet is the most common communication and research tool worldwide. Perusal of the World Wide Web quickly reveals the variety of information available. Internet adoption can be considered the late 20th century's most important event. In academic environments today, Internet use among faculty members has been widely expanded, with professors now integrating Internet technology into classroom activities. Imam Muhammad Bin Saud Islamic University (IMSU) is a pioneering public university in Saudi Arabia. Until recently, some faculty members at IMSU were unable to access the Internet through the university. It is important to study the effects of this delay on faculty members regarding research and academic activities. This study identified the statistically significant differences in demographic characteristics of Internet adopters and non-adopters among faculty members at IMSU, examined whether faculty members' perceptions of the Internet affected adoption, determined if the university administration's decisions impacted faulty members' decisions to adopt the Internet, identified factors motivating faculty members to adopt the Internet, identified obstacles influencing faculty members' decisions to use the Internet, and determined whether innovation characteristics as perceived by faculty members predicted Internet adoption. Using Rogers' diffusion of innovation theory, the influence of eight attributes were examined regarding Internet adoption among IMSU faculty members. Multiple regression and chi-square techniques were conducted to analyze the data and answer research questions. Statistically significant differences were identified among Internet adopters and non-adopters regarding gender, age, academic rank, discipline, and English proficiency. The data revealed 54.7% of IMSU faulty members used the Internet for research and academic activities twice a month or less, indicating a low Internet adoption rate. Statistically significant differences were noted among adopters and non-adopters relative to income level and English proficiency. Multiple regression analysis showed that all attributes of innovation individually predicted Internet adoption. The combination of all attributes indicated the …

An Analysis of the Characteristics of Female Juvenile Offenders as Predictors of Resocialization or Recidivism.

Description: Because there has been a paucity of research on the educational needs of females with academic, behavioral, and emotional problems involved with the juvenile justice system, this study has been an attempt to classify and compare specific characteristics of this population. In particular, it examined their demographics, disability prevalence rates, along with academic, behavioral, and emotional functioning levels, in order to further understand their relationship to the resocialization or recidivism of the different groups of female juveniles incarcerated in the state of Texas, and contribute to the research for further developing successful prevention and intervention programs. Various demographic factors of the female juveniles in this study were examined: (a) offender type, (b) county of commitment, (c) race/ethnicity, (d) age at first referral, and (e) English language proficiency. Prevalence rates of special education disabilities were determined. Academic functioning was measured by (a) IQ; (b) last school grade completed; (c) Test of Adult Basic Education (TABE) reading gain score; and (d) TABE math gain score. Behavioral functioning was indicated through (a) offense history, (b) documented behavior incidents, and (c) total risk score. Emotional functioning included DSM-IV diagnoses and treatment needs. Due to the design of the research being a descriptive exploration, the findings produced this compilation of attributes. The population of study typically reached an education level of 8th grade or less before becoming incarcerated. Their IQ is usually in the range of 80 to 90 points, with their reading and math achievement levels lagging about five years behind those of their age group. Their gains in reading and math are usually two to three levels per year. The female juveniles averaged 10 documented behavior incidents during their periods of incarceration. Their Global Assessment of Functioning (GAF) scores at intake showed they had moderate mental health symptoms and/or moderate difficulty in social, …

A regulatory role for N-acylethanolamine metabolism in Arabidopsis thaliana seeds and seedlings.

Description: N-Acylethanolamines (NAEs) are bioactive acylamides that are present in a wide range of organisms. Because NAE levels in seeds decline during imbibition similar to ABA, a physiological role was predicted for these metabolites in Arabidopsis thaliana seed germination and seedling development. There is also a corresponding increase of AtFAAH (fatty acid amide hydrolase), transcript levels and activity, which metabolizes NAE to ethanolamine and free fatty acids. Based on whole genome microarray studies it was determined that a number of up-regulated genes that were responsive to NAE were also ABA responsive. NAE induced gene expression in these ABA responsive genes without elevating endogenous levels of ABA. It was also determined that many of these NAE/ABA responsive genes were associated with an ABA induced secondary growth arrest, including ABI3. ABI3 is a transcription factor that regulates the transition from embryo to seedling growth, the analysis of transcript levels in NAE treated seedlings revealed a dose dependent, inverse relationship between ABI3 transcript levels and growth, high ABI3 transcript levels were associated with growth inhibition. Similar to ABA, NAE negatively regulated seedling growth within a narrow window of early seedling establishment. When seedlings are exposed to NAE or ABA within the window of sensitivity, the induction of genes normally associated with the ungerminated desiccation tolerant state resumed. The NAE tolerant FAAH overexpressor and the NAE sensitive FAAH knockout both had a NAE/ABA sensitive window similar to the wild type A. thaliana. The abi3-1 ABA insensitive mutant does not undergo growth arrest upon exposure to ABA, but NAE did induce growth arrest when treated within the sensitivity window. This evidence showed that although NAE functions within an ABA dependent pathway, it also functions in an ABA independent signaling pathway. The FAAH overexpressor is tolerant to NAE through its ability to quickly metabolize NAE from the …

The Global Village Playground: A qualitative case study of designing an ARG as a capstone learning experience.

Description: The Global Village Playground (GVP) was a capstone learning experience designed to address institutional assessment needs while providing an integrated, contextualized, and authentic learning experience for students. In the GVP, students work on simulated and real-world problems as a design team tasked with developing an alternate reality game that makes an impact on the United Nations Millennium Development Goals. The purpose of this study was to evaluate the effectiveness of the design of the GVP as a capstone experience. The research design follows a qualitative case study approach to gather and analyze data collected from the instructors and students participating in the pilot implementation of the GVP. Results of the study show predominantly favorable reactions to various aspects of the course and its design. Students reported to have learned the most through interactions with peers and through applying and integrating knowledge in developing the alternate reality game that was the central problem scenario for the course. What students demonstrated to have learned included knowledge construction, social responsibility, open-mindedness, big picture thinking, and an understanding of their relationship to the larger society and world in which they live. Challenges that resulted from the design included the amount of necessary to build consensus and then develop an overarching game concept, the tension between guided and directed instruction, and the need to foster greater interdependence among students while encouraging them to become more self-directed.

The Assimilation of Baroque Elements in Ferruccio Busoni's Compositions as Exemplified by the Fantasia nach Bach and the Toccata

Description: Ferruccio Busoni (1866-1924) has a firmly established reputation as one of the giant pianists of his age, yet his compositions are largely neglected both in musicological circles and on the concert stage. A better understanding of his thought processes might lead to a greater appreciation of his art, and the acknowledgement of his reverence for the music of Bach is an important key to such an understanding. Busoni's Fantasia nach Bach and Toccata, although two decidedly dissimilar compositions in terms of purpose and conception, represent two manifestations of Busoni's respect for Bach, whether it be in the form of assimilating Bach's compositions into one of his own, or by creating an original work to the same mold as some of Bach's works.

The Museum of Coming Apart

Description: This dissertation comprises two parts: Part I, which discusses use of second person pronoun in contemporary American poetry; and Part II, The Museum of Coming Apart, which is a collection of poems. As confessional verse became a dominant mode in American poetry in the late 1950s and early 60s, so too did the use of the first-person pronoun. Due in part to the excesses of later confessionalism, however, many contemporary poets hesitate to use first person for fear that their work might be read as autobiography. The poetry of the 1990s and early 2000s has thus been characterized by distance, dissociation, and fracture as poets attempt to remove themselves from the overtly emotional and intimate style of the confessionals. However, other contemporary poets have sought to straddle the line between the earnestness and linearity of confessionalism and the intellectually playful yet emotionally detached poetry of the moment. One method for striking this balance is to employ the second person pronoun. Because "you" in English is ambiguous, it allows the poet to toy with the level of distance in a poem and create evolving relationships between the speaker and reader. Through the analysis of poems by C. Dale Young, Paul Guest, Richard Hugo, Nick Flynn, Carrie St. George Comer, and Moira Egan, this essay examines five common ways second person is employed in contemporary American poetry-the use of "you" in reference to a specific individual, the epistolary form, the direct address to the reader, the imperative voice, and the use of "you" as a substitute for "I"-and the ways that the second-person pronoun allows these poems to take the best of both the confessional and dissociative modes.

Stimuli-responsive microgels for self-assembled crystalline structures and controlled drug release.

Description: Tissue response to PNIPAM and HPC nanoparticles has been studied by implantation method. The results suggest that both PNIAPM and HPC nanoparticles possess good biocompatibility and they may serve as a good carrier for the applications of controlled delivery. Rheological properties of dispersions of IPN microgels composed of PNIPAM and PAAc have been studied. It is found that the IPN microgel dispersion can undergo a sol-gel transition at temperature above 33°C. In vivo drug release experiments suggest that the gelation procedure creates a diffusion barrier and thus leads to slow release. An emulsion method has been used to grow columnar crystals by mixing PNIPAM microgel dispersions with organic solvents. Effect of both temperature and microgel concentration on formation of columnar crystals has been studied. PNIPAM-co-NMA microgels have been used for the fabrication of crystalline hydrogel films by self-crosslinking microgels. The hydrogel film exhibits an iridescent. The thermally responsive properties and mechanical properties of this film have been studied. Melting temperature (Tm) of colloidal crystals self-assembled with PNIPAM-co-AAc microgels has been investigated as a function of pH, salt concentration and microgel concentration. It is revealed that Tm increases as pH value increases; Tm decreases with increase of salt concentration; Tm increases as microgel concentration increases. Phase behavior of PNIPAM-co-HEAc microgel dispersions has been investigated. It is observed that these microgel dispersions exhibit liquid, crystal, and glass phase. As microgel size increases, crystal phase shifts to low concentration range. As temperature increases, crystal phase shifts to high concentration ranges. These colloidal crystals can be stabilized by NaOH-induced gelation. Effect of NaOH concentration on formation of physical gelation has been investigated.

A Performance Guide to Luigi Nono's Post-Prae-Ludium No. 1 "Per Donau"

Description: Luigi Nono's work Post-Prae-Ludium No.1 "per Donau" represents a model for the emerging genre of electroacoustic tuba music. It is important to preserve this electroacoustic work because of its value to the tuba literature. Not only is it one of the first electroacoustic works for the tuba, but it also was composed by a man who is highly regarded in the field of music composition. Its preservation will be difficult because of the rapid advancement in technology. Within the last three decades of existence, the technology has evolved three times. An examination of the performance practice in Post-Prae-Ludium was undertaken to understand the demand on the performer required to play this work. This study will look at both non-traditional performance practices, as well as an inherent problem of how the advancement of technology can actually threaten the survival of a work dependent upon a specific version of electronic technology. Nono worked in collaboration with Giancarlo Schiaffini to compose a work for tuba and live electronics. Correspondence with Schiaffini has provided his thoughts on the collaboration of Post-Prae-Ludium with Nono and given a better understanding of how to perform the work. Technology will change, and these current adaptations of Post-Prae-Ludium may not be valid in one or two decades. However, with the description and instruction given by Nono and Schiaffini, in addition to recordings made of Post-Prae-Ludium, there is a record from which to reproduce this work. This study provides a source allowing performers to reproduce this work, thereby preserving it for future performers.

Increasing glottal closure in an untrained male chorus by integrating historical, scientific, and clinical practice into choral voice building exercises

Description: An examination of the historical treatises of Manuel Garcia II and Giambattista Mancini, scientific studies pertaining to glottal closure, and Vocal Function Exercises used in clinical speech pathology led to an exploratory study that attempted to increase the glottal closure in an untrained university male chorus using only choral voice building exercises. The exploratory study used a single group, pre-test post-test design, and data was recorded using audio recordings of the entire chorus as well as electroglottograph measurements of individual subjects. The data show an increase in glottal closure as measured by closed quotient values, and an increase in energy in the upper partials of the recorded acoustic signal from the chorus.

Metabolic Syndrome and Psychosocial Factors

Description: Metabolic syndrome is a constellation of risk factors, including abdominal obesity, hypertriglyceridemia, low HDL cholesterol, high blood pressure, and high fasting glucose, that commonly cluster together and can result in cardiovascular disease. The prevalence of metabolic syndrome and the components that comprise the syndrome vary by age and by racial/ethnic group. In addition, previous research has indicated that the risk factors contributing to metabolic syndrome may be exacerbated by exposure to perceived stress. This study utilized data from the 2002, 2004, and 2006 Health and Retirement Study (HRS) and National Health and Nutrition Examination Survey (NHANES) data sets. It was hypothesized that depression and anxiety (conceptualized as stress in this study) increase the risk of presenting with metabolic syndrome while social support decreases the risk of metabolic syndrome. While results of cross-sectional analysis do not indicate a significant relationship between depression and metabolic syndrome (t = -.84, ns), longitudinal analysis does indicate a significant relationship between depression and metabolic syndrome over time (t = -5.20, p <.001). However, anxiety is not significantly related to metabolic syndrome when the relationship is examined through cross-sectional analysis (t = -1.51, ns) and longitudinal analysis (&#967;² = 13.83, ns). Similarly, social support is not significantly related to metabolic syndrome when examined in cross-sectional (&#967;² = .63, ns) and longitudinal (t = 1.53, ns) analysis. Although level of stress is not significantly related to metabolic syndrome as a whole, there is a significant relationship between stress and both triglyceride level (t = -2.94, p = .003) and blood glucose level (t = -3.26, p = .001).

Christian Liberal Arts Higher Education in Russia: A Case Study of the Russian-American Christian University

Description: This is a case study of the historical development of a private Christian faith-based school of higher education in post-Soviet Russia from its conception in 1990 until 2006. This bi-national school was founded as the Russian-American Christian University (RACU) in 1996. In 2003, RACU was accredited by the Russian Ministry of Education under the name Russko-Americansky Christiansky Institute. RACU offers two state-accredited undergraduate academic programs: 1) business and economics, and 2) social work. RACU also offers a major in English language and literature. The academic model of RACU was designed according to the traditional American Christian liberal arts model and adapted to Russian higher education system. The study documents the founding, vision, and growth of RACU. It provides insight into the academic, organizational, and campus life of RACU. The study led to the creation of an operational framework of the historical development of RACU. The study also provides recommendations for the development of new Christian liberal arts colleges and universities based on the experience and the underlying structure of RACU.

Ethnic Identity of Mexican American Children in the Post Industrial Age

Description: Ethnic identity of Mexican American children under the current socio-political climate was studied. Mexican American children were expected to display symptoms of ethnic ambivalence and self-rejection. Using the Kenneth and Mamie Clark (1947) Brown doll/White doll experiment as a model, data were gathered using a mixed model. This approach combed features of experimental designs, survey research, and qualitative methods. Both quantitative and qualitative data were gathered from a purposive sample of 104 children and some of their parents. They were between the ages of 3 to 15, resided in northeastern Texas, and most were White (n=70) or Hispanics (mostly Mexican American) (n=21) the remainder being Asian (n=13). Children self-identified across ethnic lines, and treated play preference, self-identification, and attractiveness separately. Children did not reflect social stereotypes and society's hierarchy. Instead, they portrayed other ethnic groups positively. Current theoretical approaches provided argue that strong ethnic identification and cultural incorporation displayed by the children may be a result of better integration and assimilation; conversely, it may be a product of the “false consciousness” driven by a global market and the culture of individualistic consumerism. An alternative theoretical perspective argues that the apparent cultural incorporation of children was a result of the social cultural evolution of race and ethnic relations in America. Children in this study were merely showing the next stage of the evolution explaining why Mexican American ethnic identity remained strong amidst the current socio-political climate. Implications and suggestions suggest that educators and policy makers should remain vigilant in promoting and facilitating multicultural programs in schools. Parents should play a role in promoting ethnic pride and appreciation of other cultures in order to ensure cultural incorporation. It is important for the social scientist to remain vigilant on the topic and not lose focus under the guise of greater assimilation between minorities …

John Nelson Darby: His Contributions to Contemporary Theological Higher Education

Description: This study investigated the contributions of John Nelson Darby to selected institutions of contemporary theological higher education. A qualitative approach to the investigation was employed. Archival foraging occupied a greater part of the research data and yielded rich returns as evidenced in the literature review. Purposeful sampling was also utilized. The faculty and administration of three institutions, Moody Bible Institute, Dallas Theological Seminary, and Emmaus Bible College, were mailed questionnaires comprising 22 questions to ascertain their opinions of Darby's contributions to their institutions. Of the 22 questions, 21 were of a Likert type scale offering 5 options: Strongly agree, Agree, Not sure, Disagree, and Strongly disagree; and 1 open-ended question. A response rate of 45% (N=27) was achieved. All results were statistically significant at the p=.05 level utilizing chi-square goodness-of-fit tests.

Computational Studies on Group 14 Elements (C, Si and Ge) in Organometallic and Biological Compounds.

Description: A series of computational studies were carried out on Group 14 (C, Si and Ge) elements in organometallic and biological compounds. Theoretical studies on classical and H-bridged A3H3+ (A=C, Si and Ge) as p ligands with different organometallic fragments at B3LYP and B3P86 level reveal a reverse charge transfer from ligand to metal in Si and Ge complexes whereas in C complexes there is a small charge transfer from metal to ligand. The H-bridged complexes are more stable than the complexes based on Si3H3+ and Ge3H3+ ligands with terminal hydrogens. The stability of the bridged systems increases from Si to Ge. Corrective scale factors for computed harmonic CºO vibrational frequencies for 31 organometallic complexes have been determined at the HF and B3LYP levels. The scaled B3LYP frequencies exhibit a greater reliability than do HF frequencies. Experimental data have shown that Si/Ge-substituted decapeptides are advantageous over their C analog in vitro and in vivo studies in modern hormone therapy. A computational investigation was carried out on the synthesized decapeptides focusing on position 5 containing Si and Ge. The results have shown that there are some differences in C, Si and Ge-containing analogs. However, further investigations are needed to elucidate the observed advantages of Si/Ge over C analogs.

Direct and Indirect Effects of Parenting Style with Child Temperament, Parent-Child Relationship, and Family Functioning on Child Social Competence in the Chinese Culture: Testing the Latent Models

Description: Interactional and contextual models have been conceptually proposed in understanding parental influences on children. Yet, empirical model testing has been limited. The purpose of this exploratory study was to investigate the direct and indirect effects of parenting style on child social competence using structural equation modeling in a sample of 544 Chinese families with 6-9 years old children, mainly singleton, residing in Nanjing, China. Five latent models were tested: (a) the direct model between parenting style and child social competence, (b) child temperament as a moderator, (c) parent-child relationship as a mediator, (d) the interaction model between parenting style and family functioning, and (e) bidirectional models of parenting style concurrently with parent-child relationship, and family functioning predicting child social competence. Findings showed: (a) The direct relationship between parenting style and child social competence was significant in both parents with authoritative parenting style on the positive direction, whereas authoritarian and permissive parenting styles on the negative direction; (b) child temperament did not moderate parenting style on child social competence; (c) father-child relationship mediated paternal parenting style on child social competence, whereas maternal parenting style did not; (d) family functioning neither moderated nor mediated the relationship between parenting style and child social competence for both parents; and (e) The four-factor prediction models on child social competence turned out to be unidirectional. For the mothers, the best model was from family functioning to mother-child relationship, to maternal parenting style, and finally to child social competence. Maternal parenting style was the significant proximal factor. For the fathers, it was from family functioning to paternal parenting style, to father-child relationship, and then to child social competence. Father-child relationship had the direct impact, whereas the influence of paternal parenting style was distal through father-child relationship. Findings from this study suggest that the Chinese parents should use …

State and local level implementation of schoolwide positive behavior support: An examination of the Texas Behavior Support Initiative (TBSI).

Description: This study examined the current status of schoolwide positive behavior support efforts in Texas. The study specifically (a) examined the impact of statewide positive behavior interventions and supports (PBIS) training on the rates of discipline records, in-school ¬suspensions, out-¬of¬-school suspensions, disciplinary alternative education placements, and expulsions of public schools in Texas; (b) investigated the overall effectiveness of schoolwide positive behavior support; and (c) determined the differences between rates of discipline records, in-school ¬suspensions, out-¬of¬-school suspensions, disciplinary alternative education placements, and expulsions in schools participating in the Texas Behavior Support Initiative (TBSI): Schoolwide PBS Project when compared with matching schools who did not participate in the project. This study demonstrated that schools can significantly reduce problem behavior in their schools when implementing PBIS with fidelity. Creating effective systems of PBIS required training, coaching, and on¬site technical assistance by trained and experienced PBIS facilitators.

Susan Botti's Cosmosis: A Conductor's Analysis with Performance Considerations

Description: In 2005, composer Susan Botti won the coveted Prix de Rome in musical composition and spent eleven months in residency at the American Academy in Rome. That same year, the University of Michigan Wind Symphony, under the direction of Michael Haithcock, premiered her exciting new work Cosmosis at the College Band Directors National Association Conference in New York City. The bi-annual conference is a venue for the premiere of new works for wind ensembles and bands, and the 2005 conference saw the world premiere of nine works for winds and percussion, many of which were performed in the legendary Carnegie Hall. What made the debut performance of Cosmosis exciting and notable was the composer's own appearance as soprano soloist, and the inclusion of a chorus of women augmenting the ensemble of winds and percussion. Such a combination of elements is unique, and created a fresh and powerful sonority. Botti's inventive approach to composition has expanded the repertoire for both women's chorus and wind ensemble with this distinctive work. This study is intended to serve as a guide to the study and performance of Cosmosis. The information provides a detailed examination of the work from its conception to its premiere performance. The work is based on the poetry of American poetess May Swenson, and Botti's interpretation of the poetry in music unveils interesting parallels between these artistic disciplines. The research provides a contextual framework from which the conductor may begin study of the work, and which may lead to an informed performance of the work.

Motives, Allusions, and Eclecticism: A Panametric Analysis of the First Movement of Christian Lindberg's Mandrake in the Corner Based on the Method of Jan LaRue

Description: For more than 20 years, Christian Lindberg has been internationally recognized as the premiere trombone soloist of our time. Few, however, are familiar with his compositions. For over ten years, he has composed many solo and ensemble works for trombone. Many prominent musical organizations in the world have performed Lindberg's music, including the Chicago Symphony Orchestra, the St. Paul Chamber Orchestra, and the University of North Texas Wind Ensemble. Today, Christian Lindberg has commission requests up to 2010. Christian Lindberg completed Mandrake in the Corner, a three movement concerto for trombone, in 1999. The purpose of this dissertation is to present an analysis of the first movement of Mandrake in the Corner to provide the first in depth study of Lindberg's compositional style. This analysis borrows freely from the method of Jan LaRue, which focuses on sound, harmony, melody, rhythm, and growth of musical structure on the small, middle, and large levels. The focus of this study centers on the aspects of melody, harmony, and rhythm to explain how the piece works despite the lack of a second theme or change of key in the first movement.

The Choral Works of Robert Ward: A View of His Compositional Approach to Text Settings and His Use of Symbols and Allusions

Description: Robert Eugene Ward's impressive body of work encompasses almost every genre of music. He has composed symphonies, operas, large orchestral pieces, chamber works, solo instrumental pieces, extended choral works, short choral pieces, ceremonial works, a ballet, theatre pieces, and even jazz and swing band pieces. Ward's name is recognized in most musical circles but usually only for his opera The Crucible, a work for which he earned a Pulitzer Prize in 1962. In fact, a survey of all the dissertations, articles, interviews, and books written about Robert Ward shows that the vast majority of these studies focus on his most famous opera. His choral works, though they comprise some of Ward's most expressive work, have received little attention. Ward's works show a deliberate use of symbols and allusions. While this use is far from an innovative concept in composition, Ward distinguishes himself with a consistent and purposeful application of these devices establishing an unmistakable interweaving of text, composition, and context. This study examines several of Ward's short choral compositions as they relate to the composer's use of symbols and allusions. Comparisons are made to Ward's use of these devices in his operatic works as a means of determining the consistency of their use throughout his vocal works. Chapter 1 looks at the composer's background, influence, and experience as to their impact on his approach to composition. Chapter 2 lays the groundwork for the discussion of symbols and allusions in music by establishing their basis and function in literary arts in general. The final chapter explores Ward's use of symbols and allusions in four of his choral works.

A paleozoological perspective on predator extermination and white-tailed deer (Odocoileus virginianus Boddaert) overabundance in central Texas.

Description: Archaeological and paleontological datasets are used in conservation to add time-depth to ecology. In central Texas several top carnivores including prehistoric Native American hunters have been extirpated or have had their historic ranges restricted, which has resulted in pest-level white-tailed deer (Odocoileus virginianus texana) populations in some areas. Predator extermination has dramatically reduced the average body size of members of the extant predator guild, and large carnivores most capable of hunting white-tailed deer are extirpated. Character release in the remaining “large” predatorsmesocarnivoresis a predicted outcome related to the adaptive vacuum at the top of the trophic hierarchy. Differences in body size of deer between prehistory and modernity are expected given that a lack of predation likely has increased intraspecific competition for forage among deer resulting in smaller body size today. In fact modern deer from settings without harvest pressure are significantly smaller than those from harvested areas and from prehistoric deer. From a natural history perspective, this research highlights potential evolutionary causes and effects of top-predator removal on deer populations and related components of biological communities in central Texas.

Analysis of the Expression Profiles of Two Isoforms of the Antifungal Protein Osmotin from Gossypium hirsutum

Description: The expression of two cotton osmotin genes was evaluated in terms of the mRNA and protein expression patterns in response to chemical inducers such as ethylene, hydrogen peroxide, and sodium chloride. Reverse transcriptase-polymerase chain reactions (RT-PCR) indicated that osmotin mRNAs are expressed constitutively in root tissues of cotton plants, and that they are rapidly induced in leaf and stem tissues upon ethylene treatment. Real time RT-PCR indicated that osmotin transcript levels were induced 2 to 4 h after treatment with ethephon. The osmotin mRNA levels appear to increase 12 h after treatment, decrease, and then increase again. The osmotin protein expression patterns were analyzed in Western blot analyses using an anti-osmotin antibody preparation. A 24-KDa protein band was detected from cotton plants treated with the inducers. The 24-KDa osmotin proteins were induced 4 h after treatment with ethephon, while down-regulated 96 h after treatment. Multiple osmotin isoforms were observed to be induced in cotton plants upon treatment with ethephon by two-dimensional gel electrophoresis. One goal of this dissertation research was to genetically engineer two cotton osmotin genes to routinely overproduce their antifungal proteins in transgenic Arabidopsis and cotton plants as a natural defense against fungal infections, using co-cultivation with Agrobacterium tumefaciens cells harboring pCAMBIA 2301 vector constructs containing the osmotin genes. Many transgenic Arabidopsis and cotton plants were generated. However, genomic blotting analyses indicated the absence of the osmotin transgenes, but the presence of GUS genes from the vector cassette. Alkaline blot analyses of the vector DNAs from transformed Agrobacterium cells confirmed that an anomalous DNA structural rearrangement or aberrant recombination event probably occurred in the Agrobacterium cells, interdicting the integration of osmotin transgenes into the Arabidopsis and cotton plants. This research provides crucial baseline information on expression of cotton osmotin mRNAs and proteins.

The historical significance of professional contributions of a leader in the field of emotional and behavioral disorders in special education: A qualitative case study of Richard J. Whelan.

Description: Historical documentation of the impact of PL 88-164 on the field of emotional and behavioral disorders (E/BD) and the development and implementation of teacher-training programs for children and youth identified as E/BD is limited. This study was designed to document the historical significance and professional contributions of Dr. Richard J. Whelan, Professor Emeritus, University of Kansas and his work in the development of teacher preparation training programs in the field of E/BD in institutions of higher education (IHE). The second purpose of this study was to document the legislative and program initiatives that have impacted the services, education, teaching, and research initiatives in the field of E/BD as interpreted by Dr. Whelan. The final purpose of this study was to examine the views of Dr. Whelan regarding the need for future developments in the field of E/BD. Legislative and policy efforts continue to change the climate in which children are educated. The field of special education relies on the efficacy of the training programs in IHE to provide appropriate teaching and research efforts in a manner that is consistent with the current needs of students with E/BD, their families, and the schools in which they seek to be educated. As this study revealed, understanding the history of the field, the foundational framework from which research and evidence-based practices have emerged, is paramount to forward movement in the field and necessary to the measurement of effective interventions and strategies in support of the students, their families, and those who choose this field as their lifework. It is the foundation from which educational theory is developed, researched, revised, and reflected.

The relationship between Adlerian personality priorities of clients and counselors and the therapeutic working alliance.

Description: The purpose of this research was to determine if a relationship exists between quality of the therapeutic working alliance and counselors' and clients' Adlerian personality priorities. Variables included counselors' and clients' Adlerian personality priorities and ratings of working alliance. Information for counselors' and clients' Adlerian personality priorities was obtained on the Allen Assessment for Adlerian Personality Priorities (AAAPP; Allen, 2005). Working alliance was measured with the Working Alliance Inventory- short revised (WAI-SR; Hatcher & Gillaspy, 2006). Participants included 14 counselors and 31 clients from a community counseling clinic on a university campus in the southwest United States. Results suggested that match between counselors' and clients' Adlerian personality priorities is related to counselors' perceptions of quality of the therapeutic working alliance. Statistically significant values were found on one hypothesis, as well as large effect sizes.
