Herbert Howells composed three large works for chorus and orchestra: a requiem (Hymnus Paradisi), Latin mass (Missa Sabrinensis) and finally a Stabat Mater. Writings, performances and recordings of the Stabat Mater, however, have been few. As the Stabat Mater is believed to be the culmination of his musical prowess, it is important to bring this major work to light. Chapter 1 begins with a brief introduction to Herbert Howells, then continues as a brief biographical sketch. Howells's life is discussed from birth, as organ scholar, student at the Royal College of Music, his teaching professorship at the same institution, and important compositions by decade until his death. Chapter 2 is an overview of the Hymnus Paradisi and Missa Sabrinensis. The chapter gives historical information on each work, including reasons for commission, dates of composition and performance, orchestration and choral composition, type of soloists, conductor and recordings. Chapter 3 is an in depth study of the Stabat Mater. The chapter includes reasons for the genesis of the work, current and past events that affected the composition, musical influences, and the death of his son Michael Kendrick Howells. A second section to this chapter addresses the text of the Stabat Mater, including …

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, …

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 …

Accurate assessment of sleep-wake patterns is important for sleep researchers and clinicians. Actigraphs are low-cost, non-intrusive, wrist-worn activity detectors used to estimate sleep-wake patterns in a natural environment for several nights. Although actigraphy shows good sensitivity (sleep detection), it has consistently demonstrated poor specificity (wakefulness detection while lying in bed relatively motionless). Because insomnia is characterized by wakefulness in bed, actigraphy may not be a valid objective measure of wakefulness for this group. It is possible that refinement of actigraphy software settings for sleep/wake algorithms might improve specificity. The current studies investigated this hypothesis by comparing wake parameters from 48 combinations of actigraphy settings to determine which sleep/wake algorithms best inform insomnia diagnosis and treatment. In the first study, none of the 48 actigraphy setting combinations consistently discriminated between adults with insomnia (n = 69) and non-insomnia (n = 80) on all three wake parameters, and no setting clearly discriminated between groups for the composite variable, total wake time. Similarly, in the second study, no setting combinations consistently discriminated between adults treated for insomnia (n = 18) and controls with untreated insomnia (n = 26) on all three wake parameters. Although two setting combinations discriminated between groups for the composite …

The effects of multiple interventions in organizational development change were studied in a comprehensive meta-analytic review. Thirteen organizational interventions were assessed on five outcome variables based upon previous research of six major meta-analytic reviews. Findings based on 138 studies indicated that there were no significant effects of multiple interventions on positive organizational change as opposed to individually implemented interventions. The findings are not congruent with previous findings of organizational development change, and possible issues surrounding these differences are discussed.

James Sellars has established himself as one of America's foremost composers whose eclectic style reveals a wealth of influences. His artistic combination of various traditional and avant-garde techniques, along with his sensitive and expert craftsmanship has earned him an important position in contemporary American music. Sellars' compositional styles have encompassed neo-Romanticism, in his early days, through post-serialism and Dada to an eclectic, post-Romantic style utilizing popular elements including electro-acoustic techniques. His extensive catalog of over 150 compositions includes works for orchestra, opera, chorus, dance, chamber, voices with ensemble, solo voice, piano, instrumental solos, band, and media. Sellars' compositions for piano solo span a 38-year period and total 17 works, the most important of which are his six one-movement sonatas, which represent, according to Sellars, "a journey from modernism to post-modernism." Their value lies in their eclectic stylistic approaches, artistic nd technical challenges, and pianistic effectiveness. The first three sonatas, incorporating post-serial elements, fall into a modernist stylistic stance while numbers four through six, in postmodern style, contrast one another drastically. Sonata Brasileira, recalls the broad sweeping gestures of the Romantic period; Sonata V reveals the influence of the absurdist Dada movement; and the last sonata Patterns on a Field, blends …

Organizational change and development (OCD) has been studied by researchers to identify the effectiveness of change initiatives. Because of the broad scope of interventions in OCD, these studies have covered a range of areas including multiple interventions and the methodological rigor used by researchers. However, few have looked at organizational versus individual change within an organization, to examine whether individual change is more effective than organizational change. The purpose of this study is to determine if organizational change occurs in a top down or bottom up manner. A meta-analysis was conducted using 238 field experiments. Each study was coded for intervention and organizational outcome and for individual or organizational level variables. Effect sizes were calculated for each study, each level, and each level by intervention and outcome measure. Results indicate that while OCD interventions overall had a moderate effect size, the level of intervention or outcome was not a moderating variable.

Archive Activism is a memoir of activism rooted in a new way to converse with history—by rescuing it. Archive activists discover documents and other important materials often classified, “gone missing,” or sealed that somehow escaped the fireplace or shredder. It is an approach to LGBTQ advocacy and policy activism based on citizen archivery and original archival research to effect social change. Research=Activism is the formula growing out of Charles Francis’s personal story as a gay Texan born and raised during the 1950s and 1960s in Dallas. The rescues range in time and place from Francis’s first encounter with a raucous, near-violent religious demonstration in Fort Worth to attics loaded with forgotten historic treasures of LGBTQ pioneers. Archive Activism tells how Francis helped Governor George W. Bush achieve his dream of becoming president in 2000 by reaching out to gay and lesbian supporters, the first time a Republican candidate for president formally met with gay and lesbian Americans. This inspired Francis to engage with deleted LGBTQ history by forming a historical society with an edge, a new Mattachine Society of Washington, DC. For the first time, Archive Activism reveals how LGBTQ secrets were held for decades at the LBJ Presidential Library …

This mixed-methods dissertation used an explanatory sequential design to examine art and mathematics preservice teachers' perceptions and attitudes towards integrating art and mathematics (IAM) after an IAM workshop. The conceptual framework of this study has its basis in three theoretical sources: constructivism, multiple intelligence theory, and semiotics. Each of these sources provides a conceptual lens to examine art integration in the curriculum and the teacher's role in facilitating this instructional process. Participants of this study included two sub-groups at a large university in Saudi Arabia. The first sub-group was preservice teachers of art education. The second sub-group was preservice teachers of mathematics. Quantitative and qualitative results indicated that the IAM workshop had positive impacts on art and mathematics preservice teachers' attitudes and perceptions of IAM. Participants attributed more value to art, were more willing to apply IAM, and felt that there was less barriers for applying IAM. The study also indicated differences between art and mathematics preservice teachers' attitudes towards IAM. The differences were due more to art value than willingness or barriers. After the IAM workshop, mathematics preservice teachers put more emphasis on the importance of art to mathematics, especially with respect to making mathematics a more enjoyable subject.

Taxonomic composition and spatio-temporal variability of macroinvertebrates inhabiting snags were examined from an 8-km segment of the Elm Fork of the Trinity River. Seventy-seven macroinvertebrate taxa were collected from submerged wood during the study. Assemblages were highly variable spatially and temporally, especially among seasons. An ordination of species and environment did not find snag taxa to have striking correlations with many of the selected environmental variables, although there were some trends in flow-mediated species distributions. There were significant seasonal differences in the abundances of some taxa, particularly among the Chironomidae (Diptera). The Tribe Orthocladiini was numerically abundant during the winter, while the Tribes Chironomini and Tanytarsini dominated the summer and autumn. Additionally, this study included a secondary production and microdistribution analysis of a population of the caddisfly Cyrnellus fraternus. Distributions of C. fraternus were restricted to snags, the most stable substratum for retreat building and for resisting periodic high waters. Larvae were not found in the soft sand and mud benthic habitats near submerged wood. The insects were multivoltine with a minimum of three generations per year. Pupae were collected July through September and adults emerged from May through October. The population overwintered as larvae. Estimated annual production was 1,015.4 …

This study investigates the correlation between students' learning styles, computer competency and student satisfaction in Web-based distance learning. Three hundred and one graduate students participated in the current study during the Summer and Fall semesters of 2002 at the University of North Texas. Participants took the courses 100% online and came to the campus only once for software training. Computer competency and student satisfaction were measured using the Computer Skill and Use Assessment and the Student Satisfaction Survey questionnaires. Kolb's Learning Style Inventory measured students' learning styles. The study concludes that there is a significant difference among the different learning styles with respect to student satisfaction level when the subjects differ with regard to computer competency. For accommodating amd diverging styles, a higher level of computer competency results in a higher level of student satisfaction. But for converging and assimilating styles, a higher level of computer competency suggests a lower level of student satisfaction. A significant correlation was found between computer competency and student satisfaction level within Web-based courses for accommodating styles and no significant results were found in the other learning styles.

Team-based management is a popular contemporary method of redesigning jobs in order to more effectively utilize the human potential of employees. The use of such management techniques should result in increased satisfaction and team commitment; however, many research studies have failed to demonstrate increases in affective outcomes on the part of the employee. The research question examined in this study is, "What specific job dimensions and situational factors result in higher levels of satisfaction and team commitment?" The Job Characteristics Model (Hackman & Oldham, 1975) provided a basis for this study. The model was designed for individual contributors and has not been extensively used in team research. As expected it was found that within a team-based environment higher levels of the five core job dimensions of skill variety, task identity, task significance, autonomy, and job feedback were associated with increased satisfaction and team commitment. Organization-based self-esteem was found to mediate the relationship between the five core job dimensions and the affective outcome variables. Contrary to expectations, however, it was found that consultative team members experienced higher levels of satisfaction and commitment than substantive team members. In addition, consultative team members reported higher levels of two core job dimensions, skill variety …

Frank Reaugh (1860–1945; pronounced “Ray”) was called “the Dean of Texas artists” for good reason. His pastels documented the wide-open spaces of the West as they were vanishing in the late nineteenth century, and his plein air techniques influenced generations of artists. His students include a “Who’s Who” of twentieth-century Texas painters: Alexandre Hogue, Reveau Bassett, and Lucretia Coke, among others. He was an advocate of painting by observation, and encouraged his students to do the same by organizing legendary sketch trips to West Texas. Reaugh also earned the title of Renaissance man by inventing a portable easel that allowed him to paint in high winds, and developing a formula for pastels, which he marketed. A founder of the Dallas Art Society, which became the Dallas Museum of Art, Reaugh was central to Dallas and Oak Cliff artistic circles for many years until infighting and politics drove him out of fashion. He died isolated and poor in 1945. The last decade has seen a resurgence of interest in Reaugh, through gallery shows, exhibitions, and a recent documentary. Despite his importance and this growing public profile, however, Rounded Up in Glory is the first full-length biography. Michael Grauer argues for Reaugh’s …

The purpose of this study was to evaluate the effects of a training package consisting of response restriction and the reinforcement of self-evaluation on letter reversal errors. Participants were 3 typically developing boys between the age of 5 and 7. The results indicated that the training package was successful in correcting reversals in the absence of a model during training and on application tests. These improvements maintained during subsequent follow-up sessions and generalized across trainers. Fading was not always necessary in correcting reversals, but was effective in correcting reversals that persisted during the overlay training procedures. The advantages to implementing a systematic intervention for reducing letter reversal errors in the classroom, as well as directions for future research, are discussed.

The primary purpose of this study was to use some of the action methods of playback theatre to facilitate the acquisition of knowledge through the experience of building community. The impact of action methods on group dynamics and the relationship among methods, individual perceptions, and the acquisition of knowledge were analyzed. The researcher suggested that playback theatre action methods provided a climate in which groups can improve the quality of their interactions. The Hill Interaction Matrix (HIM) formed the basis for the study's analysis of interactions. Since the researcher concluded there were significantly more interactions coded in the "power quadrant" after training, the researcher assumed that playback theatre action methods are a catalyst for keeping the focus on persons in the group, encouraging risk-taking behaviors, and producing constructive feedback between members. Based on session summaries, individual interviews, and an analysis of the Group Environment Scale (GES), the training group became more cohesive, became more expressive, promoted independence, encouraged self-discovery, and adapted in innovative ways. The experience of an interconnected community created a space where positive growth could occur. The researcher concluded that the process of community building is intricately connected with a person's ability to make meaning out of experiences. …

Ben Thompson was a remarkable man, and few Texans can claim to have crowded more excitement, danger, drama, and tragedy into their lives than he did. He was an Indian fighter, Texas Ranger, Confederate cavalryman, mercenary for a foreign emperor, hired gun for a railroad, an elected lawman, professional gambler, and the victor of numerous gunfights. As a leading member of the Wild West’s sporting element, Ben Thompson spent most of his life moving in the unsavory underbelly of the West: saloons, dance-houses, billiard halls, bordellos, and gambling dens. During these travels many of the Wild West’s most famous icons—Wyatt Earp, Doc Holliday, Bat Masterson, Wild Bill Hickok, John Wesley Hardin, John Ringo, and Buffalo Bill Cody—became acquainted with Ben Thompson. Some of these men called him a friend; others considered him a deadly enemy. In life and in death no one ever doubted Ben Thompson’s courage; one Texas newspaperman asserted he was “perfectly fearless, a perfect lion in nature when aroused.” This willingness to trust his life to his expertise with a pistol placed Thompson prominently among the western frontier’s most flamboyant breed of men: gunfighters.

This study assessed alumni of the College and University Teaching Program at the University of North Texas and how they perceived the training they received. Three hundred sixty alumni holding a college and university teaching degree were surveyed. One hundred forty-two usable questionnaires were returned. A response rate of 39.4 % was achieved. A survey instrument was used to gather alumni perceptions of learning experiences, academics, and professional benefits as a result of earning a doctorate in the major of college and university teaching at the University of North Texas. Alumni were asked their perceptions on the following: 1) the quality of graduate professional education in college and university teaching degree program, 2) whether they thought the goals and objectives of the program were met, and 3) their recommendations regarding the college and university teaching degree program. It is the overall opinion of the alumni that the quality of the graduate education in college and university teaching degree program was high. The majority of alumni indicated that the program should be reinstated and continued and if the program was still available they would recommend it to others.

"Harry Partch's Keyboard Innovation" is a computer-assisted demonstration that introduces the tuning system used primarily by the twentieth-century American composer, Harry Partch. The multimedia product was developed in Director 6.0, and it includes sound and video clips from CDs and videocassettes of Partch's works produced by Phillip Blackburn and distributed by the American Composers Forum. The content of the demonstration involves a 43-tone microtonal tuning system and its application in the music literature. This demonstration will discuss the chronological order in which these prototypes were developed and also includes samples of the tuning of notes in Partch's scale that the novice can experiment with interactively. These tones were synthesized using the Csound scores shown in Appendix B. Materials for this demonstration are based on Harry Partch's Genesis of a Music.

Pinned down by a posse, the wounded outlaw’s companions urged him to escape through the gulch. “Don’t wait for me,” he replied, “I’m all in and might as well end it right here.” Placing his revolver to his right temple, he pulled the trigger for the last time, thus ending the life of the notorious “Kid Curry” of the Wild Bunch. It is long past time for the publication of a well-researched, definitive biography of the infamous western outlaw Harvey Alexander Logan, better known by his alias Kid Curry. In Wyoming he became involved in rustling and eventually graduated to bank and train robbing as a member—and soon leader—of the Wild Bunch. The core members of the gang came to be Butch Cassidy, the Sundance Kid, George “Flatnose” Currie, Elzy Lay, Ben “the Tall Texan” Kilpatrick, Will Carver, and Kid Curry. Kid Curry has been portrayed as a cold-blooded killer, without any compassion or conscience and possessed of limited intelligence. Curry indeed was a dangerous man with a violent temperament, which was aggravated by alcoholic drink. However, Smokov shows that Curry’s record of kills is highly exaggerated, and that he was not the blood-thirsty killer as many have claimed. Mark …

Relationships between the collective actors within interorganizational relationships are a growing area of research in management. Interorganizational networks continue to be a popular mechanism used by organizations to achieve greater performance. Organizations develop competencies to work with other organizations, but the confidence of these organizations to use these strengths for a competitive advantage has yet to be empirically examined. The purpose of this study is to examine organizational efficacy, how competencies may related to that efficacy, and the relationship of efficacy with performance. The goal of this study is to observe the relationship among trust, dependence, information quality, continuous quality improvement, and supplier flexibility with organizational efficacy. In addition, the relationship between organizational efficacy and performance is also observed. There are two primary research questions driving this study. First, what is the relationship between trust, dependence, information quality, continuous quality improvement, supplier flexibility and organizational efficacy? Second, what is the relationship between organizational efficacy and performance? The theories supporting the hypotheses generated from these questions include theories such as social cognitive theory, quality improvement, and path-goal theory. Data collected from the suppliers of a large university support the hypotheses. Regression analysis and structure coefficients were used to analyze the data. …

Few studies have investigated methods for establishing neutral stimuli as conditioned reinforcers in human subjects. Conditioned reinforcers, however, can alleviate some of the problems encountered in applied behavior analytic (ABA) therapy for children with autism, such as satiation and suitability of reinforcers for specific environments. A series of reversals evaluated the effects of a conditioning procedure involving pairing a neutral stimulus, the remote control stimulus (RCT), with an identified reinforcer. Phase 1 demonstrated that the RCT was neutral. In Phase 2, alternating pairing and testing conditions were run. During testing the effects of pairing were evaluated by the effectiveness of the RCT in maintaining a response in the absence of a previously available reinforcer (extinction test) and in increasing a new response over a baseline level (learning test). Results from the extinction test suggest that under some pairing conditions the RCT can acquire properties of a reinforcer.

The purpose of this study was to identify perceived barriers to faculty participation in distance education courses in a 4-year university. The literature review was divided into four general areas, each of which may act as a barrier to faculty participation; training, administrators, rewards/compensation, and faculty characteristics/demographics. The research population consisted of 570 faculty and 59 administrators from the eight UNT schools/colleges. Dr. Kristin Betts developed the survey instrument in 1998 for similar research conducted at the George Washington University. Analysis of the collected data revealed that there was no statistically significant relationship found between faculty characteristics and faculty participation in distance education. Faculty participants and administrators disagreed on which factors, from a list of 34 items, had motivated faculty to participate in distance education. Nonparticipants and administrators disagreed on which of the factors, if not available, would be barriers to faculty participation in distance education. Participants and nonparticipants disagreed regarding the level to which selected rewards and compensations had motivated faculty to participate, and the lack of which would inhibit faculty participation in distance education. Finally, 71% of the participants had participated or planned to participate in distance education training compared to only 33% of the nonparticipants. It is …

In this research, hyperspectral and multispectral images were utilized for vegetation studies in the greenbelt corridor near Denton. EO-1 Hyperion was the hyperspectral image and Landsat Thematic Mapper (TM) was the multispectral image used for this research. In the first part of the research, both the images were classified for land cover mapping (after necessary atmospheric correction and geometric registration) using supervised classification method with maximum likelihood algorithm and accuracy of the classification was also assessed for comparison. Hyperspectral image was preprocessed for classification through principal component analysis (PCA), segmented principal component analysis and minimum noise fraction (MNF) transform. Three different images were achieved after these pre-processing of the hyperspectral image. Therefore, a total of four images were classified and assessed the accuracy. In the second part, a more precise and improved land cover study was done on hyperspectral image using linear spectral unmixing method. Finally, several vegetation constituents like chlorophyll a, chlorophyll b, caroteoids were distinguished from the hyperspectral image using feature-oriented principal component analysis (FOPCA) method and which component dominates which type of land cover particularly vegetation were correlated.

Abstract Attracting and developing information technology (IT) professionals is one of the top concerns for companies. Although much research has been conducted about the job behavior and attitudes of IT professionals over the last three decades, findings are inconclusive and contradictory. This suggests that something may be missing in how we examine this phenomenon. Most of this research is drawn from theories of motivation, very little examines the effect of social relationships on IT professionals' behavior and attitude. Yet, social capital theory suggests that job behavior and attitude may be greatly influenced by these relationships. This suggests that IT professionals' social capital warrants empirical examination. The primary research question that this dissertation addresses is how social capital affects IT professionals' work attitude and behavior including job satisfaction, organizational citizenship behavior, job performance and turnover intention. The research model in this dissertation examines the influence of three aspects of social capital on IT professionals' job attitude and work behavior: tie strength, the number of ties and the structural holes. Data were collected from 129 IT professionals from a range of jobs, organizations and industries. Results indicate that tie strength in the organization of an IT professional is positively related to job …
