The Aesthetics of Minimalist Music and a Schenkerian-Oriented Analysis of the First Movement "Opening" of Philip Glass' Glassworks

Description: Philip Glass' Glassworks (1981) is a six-movement composition for two flutes, two soprano saxophones/clarinets, two tenor saxophones/bass clarinets, two French horns, violas, cellos, and the DX7 electric piano. Glassworks consists of six movements titled "Opening," "Floe," "Island," "Rubric," "Facades," and "Closing." This thesis covers the first movement "Opening." Repetition in musical minimalism confronts traditional prescriptive codes of tonal music and post-tonal music. While challenging the traditional codes, repetition in musical minimalism established new codes for listening to minimal music. This thesis explores the implications of these ideas.

Affective and cognitive components of job satisfaction: Scale development and initial validiation.

Description: Job satisfaction is one of the most commonly studied variables in the organizational literature. It is related to a multitude of employee-relevant variables including but not limited to performance, organizational commitment, and intent to quit. This study examined two new instruments measuring the components of affect and cognition as they relate to job satisfaction. It further proposed including an evaluative (or true attitudinal) component to improve the prediction of job satisfaction. Results provide some evidence of both two and three factor structures of affect and cognition. This study found minimal support for the inclusion of evaluation in the measurement of job satisfaction. Affect was found to be the single best predictor of job satisfaction, regardless of the satisfaction measure used. Further development is needed to define the factor structures of affect and cognition as well as the role of these factors and evaluation in the prediction of job satisfaction.

Affordances of External Representations in Instructional Design: The Effect of Narrative and Imagery in Learning.

Description: Consisting of both theoretical and empirical inquires, this study examines the primary functions of narrative and the relationship between narrative and mental imagery. The study proposes a new framework to interpret semiotic resources. Combining this with the linguistic functional theory of Halliday (1978), a functional method to empirically investigate semiotic representations was also developed. In the empirical inquiry, the study developed a latent construct method to empirically test the effects of narrative in a real learning situation. This study is the first to investigate the functional relationship between narrative and mental imagery, and among the first to suggest a theory and empirically investigate representations of a multimodal nature. The study is also among the first to use latent constructs to investigate the learning experience in a real educational setting. Data were collected from 190 library professionals who enrolled in three sections (two in narrative and one in plain text) of an online course administered through Vista 4.0 and who completed the course and responded to several instruments. Essay data (n = 82 x 2) were analyzed using content analysis based on the narrative analysis framework developed. Quantitative data analysis methods include univariate data analysis, factor analysis, and structural equation modeling that tests the proposed model and verifies the relationships between the latent variables. Overall, the findings support the hypotheses about the functional effects of narrative identified, and narrative is found to provide a favorable and positive learning context which is tested by the proposed model of learning experience measured by several latent constructs (X2 = 31.67, df = 47, p = .9577, RMSEA = .00, SRMR = .047, NNFI = 1.05, CFI = 1.00, and GFI = .94). The results indicate that participants who enrolled in the narrative sections of the course gained higher creative scores and showed better results ...

African-American Parents' Nutritional Habits: Implications for the Prevention of Early Childhood Obesity.

Description: This research study addressed the nutritional beliefs and habits of African-American parents of children aged 3 to 6 years old. Both quantitative and qualitative data collection methods were employed. Quantitative data was collected via the Comprehensive Feeding Practices Questionnaire as well as a demographic questionnaire. Qualitative data was collected from oral interviews conducted by the researcher. Seventy-five parents or guardians participated in the study. Findings for the research questions revealed the participants' beliefs about nutrition directly correlated with food they provided for their children and most believed nutrition rather than genetics played a role in their child(ren)'s weight. Furthermore, parents from lower income families consumed more home cooked meals per week and those with higher incomes did not consume more fast food per week. Food intake restriction and control in feeding was similar among all participants, regardless of restriction and control in feeding was similar among all participants, regardless of education or income level. Suggestions for future research were included.

African Refugee Parents' Involvement in Their Children's Schools: Barriers and Recommendations for Improvement

Description: The purpose of this study was to examine involvement of African refugee parents in the education of their elementary school children. The setting of the study was Northern and Southern Texas. African refugee parents and their children's teachers completed written surveys and also participated in interviews. In the study's mixed-method design, quantitative measures provided data about parent involvement at home, parent involvement at school, frequency of parent-teacher contact, quality of parent-teacher relationship, parent endorsement of children's schools, and barriers to parent involvement. Qualitative data from the open-ended questions provided data on barriers and strategies to improve involvement. Sixty-one African refugee parents responded to the survey and also participated in an in-depth face-to-face or telephone interview. Twenty teacher participants responded to an online survey. Quantitative data gathered from the parent and teacher surveys were analyzed using frequency distributions and analyses of variance. Qualitative data were analyzed by summarizing and sorting information into different categories using Weft QDA, an open-source qualitative analysis software. From these data, I identified barriers to African refugee parent involvement in their children's schools, as well as challenges that teachers face as they try to involve African refugee parents. Results of analyses of variance revealed statistically significant differences in parent involvement between African refugee parents with limited English proficiency and those with high English proficiency. A key finding of the research was that, whereas the overall level of parent involvement for African refugee parents was low, a major barrier to involvement was language. Teachers and parents cited enrolment in English as a second language programs as the best strategy to enhance parent involvement of African refugees. Additionally, parents who reported higher education levels were more involved in their children's education both at home and at school. All groups of African refugee parents reported high endorsement of their children's ...

Age and Responses to the Events of September 11, 2001

Description: Following the terrorist attacks on the United States on September 11, 2001, many turned to the field of psychology for greater understanding of the impact of such events and guidance in supporting our citizens. This study sought to gain greater understanding of the differential impact of the September 11th attack on individuals by investigating the influence of age, psychological hardiness, and repression versus sensitization as forms of coping behavior on psychological health. Both an initial cross-sectional sample (172 young adults & 231older adults) and a short-term longitudinal follow-up (39 young adults & 58 older adults) were included in the study. Older age, psychological hardiness and the use of a repressing coping style were found to each individually relate to greater resilience/less dysfunction at both time one and two. For young adults, high hardy repressors faired best, followed by high hardy sensitizers. Low hardy young adults demonstrated similar levels of dysfunction regardless of coping style (repressions/sensitization). For older adults, coping style impacted both high and low hardy individuals equally, with high hardy repressors demonstrating greater functioning. This study attempted to gain greater insight into explanations for these and previous findings of greater resilience among older adults. In explaining the greater resilience of older adults, it seems that coping style is highly important, while hardiness and the impact of history-graded events does not explain the resilience of older adults.

Age-Dependent Effects Of Chronic GABAA Receptor Blockade In Barrel Cortex

Description: GABAA receptor binding is transiently increased in rat whisker barrels during the second postnatal week, at a time when neurons in the developing rat cortex are vulnerable to excitotoxic effects. To test whether these GABAA receptors might serve to protect neurons from excessive excitatory input, polymer implants containing the GABAA receptor antagonist bicuculline were placed over barrel cortex for a 4-day period in young (postnatal days 8 - 12) and adult rats. In the cortex of young, but not adult rats, the chronic blockade of GABAA receptors resulted in substantial tissue loss and neuron loss. The greater loss of neurons in young rats supports the hypothesis that a high density of GABAA receptors protects neurons from excessive excitatory input during a sensitive period in development.

Agent Extensions for Peer-to-Peer Networks.

Description: Peer-to-Peer (P2P) networks have seen tremendous growth in development and usage in recent times. This attention has brought many developments as well as new challenges to these networks. We will show that agent extensions to P2P networks offer solutions to many problems faced by P2P networks. In this research, an attempt is made to bring together JXTA P2P infrastructure and Jinni, a Prolog based agent engine to form an agent based P2P network. On top of the JXTA, we define simple Java API providing P2P services for agent programming constructs. Jinni is deployed on this JXTA network using an automated code update mechanism. Experiments are conducted on this Jinni/JXTA platform to implement a simple agent communication and data exchange protocol.

Agreement Between Self and Other Ratings in Multi-Rater Tools: Performance, Alternative Measures, and Importance.

Description: Multi-rater tools also referred to as 360-degree feedback tools, are frequently used in addition to traditional supervisory appraisals due to sources (i.e., supervisor, peer, direct report) unique perspectives and opportunities to view different aspects of job performance. Research has found that the differences among sources are most prevalent between self and other ratings, and the direction of agreement is related to overall job performance. Research has typically focused on one form of agreement, the direction of an individual's self-ratings compared to others' ratings. The current study expanded on past research on rater agreement using a data set (n = 215) consisting of multi-rater data for professionals participating in a leadership development process. The study examined the ability to predict job performance with three different measures of self-other agreement (i.e., difference between overall mean scores (difference), mean absolute difference across items (difference), and mean correlation across items (similarity)). The study also examined how the relationships may differ across performance dimensions. The final purpose was to explore how the importance of the performance dimensions, as rated by the participant, may moderate the relationship between self-other agreement and job performance. Partial support for study's hypotheses was found. The direction and difference measures of agreement on the overall multi-rater tool and performance dimensions accounted for a significant amount of the variance in job performance. The relationship between the similarity measure of agreement and job performance, and the moderating effect of importance were not supported in the current study.

Alberto Grau: The Composer, Selected Works, and Influence upon the Venezuelan and International Choral Community

Description: Alberto Grau is arguably one of the most influential contemporary Venezuelan choral composers and conductors of the twentieth and twenty-first centuries. This thesis explores the synthesis of Venezuelan nationalism with global internationalism found within his works. As a student of the nationalistic generation of composers (Vicente Emilio Sojo, Juan Bautista Plaza, and Ángel Sauce) Grau's works display the distinct characteristics found in Venezuelan music. His output also exhibits international influences, using texts associated with social and environmental events and concerns including literary and musical influences of other nations and cultures. The first section of the thesis traces the lineage of Venezuelan choral composers beginning with the colonial period and the Escuela de Chacao to the nationalistic composers from the Santa Capilla generation. The second section describes Alberto Grau's compositional style as exemplified in his work Kasar mie la gaji (The Earth is Tired). The final section of the document comprises interviews with Alberto Grau and his wife, the Venezuelan choral conductor, María Guinand. Guinand studied piano and conducting with Alberto Grau and was his assistant at the Orfeón Universitario Simón Bolívar and the Schola Cantorum de Caracas. She is the founding conductor of the Cantoría Alberto Grau and the editor of the Latin American division of Earthsongs Music. Through interviews and analysis this project informa the reader about the life and compositions of Venezuelan choral composer and conductor Alberto Grau.

Alcohol and Other Drugs: Attitudes and Use Among Graduate/Professional Students at a Health Science Center

Description: Alcohol and other drug use continue to be a major issue on college and university campuses. Few studies have examined alcohol and other drug related issues for a graduate or professional student population. This study examines attitudes, incidents, and consequences of alcohol and other drug use among students enrolled at an academic heath science center. This study incorporated a descriptive research design and utilized the CORE Alcohol and Drug Survey for the collection of data. The data were then analyzed using descriptive statistics and represented in tables as frequencies and percentages. The survey was mailed to all students enrolled in didactic course work at the University of North Texas Health Science Center (UNTHSC) during the fall 2001 semester. This included master's students in physician assistant studies, master's and doctoral students in the biomedical sciences, master's and doctoral students in public health, as well as first and second year medical students. Of the 565 students enrolled in didactic course work, 321 responded to the survey for a return rate of 56.8 %. Statistically significant findings are reported for students at UNTHSC in relation to perceptions of use, actual use, reasons for use, and consequences for use. Similar findings are shown relative to age, gender, marital status, ethnicity, and academic program. Additionally, the UNTHSC students reported statistically significant lower levels of alcohol and drug use, as well as consequences of use than the students represented in the CORE Institutes 2000 national data set. This study identifies the need to investigate alcohol and drug related attitudes, behaviors, and consequences among students studying for professions in health related fields. However, the findings are only relevant to UNTHSC and cannot be generalized to any other population. The study provides personnel at UNTHSC a guide for the development of prevention and intervention programs.

Alexander Johnson's Ni' Concerto (1994) - Concerto no. 1 for Piano and Orchestra: a Discussion of Influences from Africa, Eastern and Western Europe

Description: In the new generation of artists emerging in South Africa, Alexander Johnson is considered the most prolific young composer of his day. In a recent review in the Pretoria News, Johnson has been praised by eminent critic Paul Boekkooi as a composer who has “an ear for the exotic and knows exactly how to bring it off....” He continued by noting that his music is “mentally engrossing, pleasurable to the senses and seems refreshingly free from dogmatic formulas." Johnson writes for musicians and the general public to equal satisfaction. His accessible compositions and catching use of melodic materials have made his writings very popular both in South Africa and abroad. During his residency in Belgrade in 1993-94, Johnson met Croatian pianist Dorian Leljak. Impressed with Johnson's compositional ideas and output, Leljak commissioned a work from Johnson for piano and orchestra. The result was the Niš Concerto, which Johnson completed in April 1994. The world premiere took place on June 23, 1994 with the Niš Philharmonic Orchestra conducted by Anatoli Nowiestski with Dorian Leljak as soloist. The Niš Concerto received its South African premiere in 1995 during a simultaneous celebration for “Europe Day” and the new democracy of the Republic of South Africa. The Delegation of the European Commission of South Africa sponsored the celebration, which took place in the Aula Auditorium on the campus of the University of Pretoria. The performers included the Artium Symphony Orchestra, conducted by Dutch-born Prof. Henk Temmingh and Johnson himself as piano soloist.

Alexander Scriabin (1871-1915): Piano Miniature as Chronicle of his Creative Evolution; Complexity of Interpretive Approach and its Implications.

Description: Scriabin's piano miniatures are ideal for the study of evolution of his style, which underwent an extreme transformation. They present heavily concentrated idioms and structural procedures within concise form, therefore making it more accessible to grasp the quintessence of the composer's thought. A plethora of studies often reviews isolated genres or periods of Scriabin's legacy, making it impossible to reveal important general tendencies and inner relationships between his pieces. While expanding the boundaries of tonality, Scriabin completed the expansion and universalization of the piano miniature genre. Starting from his middle years the 'poem' characteristics can be found in nearly every piece. The key to this process lies in Scriabin's compilation of certain symbolical musical gestures. Separation between technical means and poetic intention of Scriabin's works as well as rejection of his metaphysical thought evolution result in serious interpretive implications. Music of Scriabin provides an excellent opportunity for a performer to find a proper balance between rational and intuitive. The lack of any of these qualities will impoverish his works, making their interpretation incomplete. Following one of main Scriabin's ideas - synthesis of all arts - this study approaches his music not from the narrow analytical, but broad synthetic standpoint. The suggested solution is an informed performance, based on Heinrich Neuhaus's teaching method that encompassed all arts. 'Cross-art' comparative analysis justifies the composer's artistic searches and highlights significance of his ideas, which disclose a strong correlation with the characteristic features of the creative faculty, the nature of music and its synergetic aspects.

Algorithms for Efficient Utilization of Wireless Bandwidth and to Provide Quality-of-Service in Wireless Networks

Description: This thesis presents algorithms to utilize the wireless bandwidth efficiently and at the same time meet the quality of service (QoS) requirements of the users. In the proposed algorithms we present an adaptive frame structure based upon the airlink frame loss probability and control the admission of call requests into the system based upon the load on the system and the QoS requirements of the incoming call requests. The performance of the proposed algorithms is studied by developing analytical formulations and simulation experiments. Finally we present an admission control algorithm which uses an adaptive delay computation algorithm to compute the queuing delay for each class of traffic and adapts the service rate and the reliability in the estimates based upon the deviation in the expected and obtained performance. We study the performance of the call admission control algorithm by simulation experiments. Simulation results for the adaptive frame structure algorithm show an improvement in the number of users in the system but there is a drop in the system throughput. In spite of the lower throughput the adaptive frame structure algorithm has fewer QoS delay violations. The adaptive call admission control algorithm adapts the call dropping probability of different classes of traffic and optimizes the system performance w.r.t the number of calls dropped and the reliability in meeting the QoS promised when the call is admitted into the system.

Aliens and atheists: The Plurality of Worlds and Natural Theology in Seventeenth-Century England.

Description: The plurality of worlds has had a long history in England, which has not gone unnoticed by scholars. Historians have tended to view this English pluralist tradition as similar to those found on the continent, and in doing so have failed to fully understand the religious significance that the plurality of worlds had on English thought and society. This religious significance is discovered through a thorough investigation of plurality as presented by English natural philosophers and theologians, and in so doing reveals much about England in the seventeenth century. As natural philosophers incorporated plurality within the larger framework of natural theology, it became a weapon of science and reason to be used against the unreasonable atheists of late seventeenth-century England.

Alternative Information Processing Formats for Overcoming Information Processing Deficits in Senior Adults

Description: The objective of this study was to examine the effectiveness of alternative advertising presentation formats, and the quantity of information presented in advertisements in overcoming possible information-processing deficits in senior adults that could affect their recall of ad attributes and brand name, the cognitive responses generated, and attitude toward the ad. In addition, the study examined the effectiveness of retirement status as a classification or segmentation variable in comparison with the use of the more traditional classification variable, chronological age. A convenience sample of senior adult volunteers from church groups, social clubs, and civic organizations from the local area were randomly assigned to one of nine experimental conditions. The experiment utilized a simulated magazine to test the effects of presentation formats (3 levels), and quantity of information (3 levels) on senior adult's recall, cognitive responses and attitude toward the test ads. Covariates (gender, wealth, education, activity level, health, and income) were used to reduce variance. The findings clearly indicate that the presentation format of the can ad adversely affected the memory of some senior adults. In addition, the results were significantly different across the different age levels. Retirement status was less beneficial than chronological age in the current study, but did reveal a marginally significant difference between seniors due to the number of attributes contained in the test ads. The implication of findings for advertisers and those who design marketing communications for seniors are numerous, and relate to the marketer's communication goals. Senior adults may prefer print media, but the inappropriate use of presentation format and the number of product attributes in the ads could have an adverse and significant impact when communicating with senior adults. Recognition of the information-processing differences of senior adults would result in more effective marketing communications for this rapidly growing and important segment of our ...

Always Painting the Future: Utopian Desire and the Women's Movement in Selected Works by United States Female Writers at the Turn of the Twentieth Century

Description: This study explores six utopias by female authors written at the turn of the twentieth century: Mary Bradley Lane's Mizora (1881), Alice Ilgenfritz Jones and Ella Merchant's Unveiling Parallel (1893), Eloise O. Richberg's Reinstern (1900), Lena J. Fry's Other Worlds (1905), Charlotte Perkins Gilman's Herland (1915), and Martha Bensley Bruère's Mildred Carver, USA (1919). While the right to vote had become the central, most important point of the movement, women were concerned with many other issues affecting their lives. Positioned within the context of the late nineteenth century women's rights movement, this study examines these "sideline" concerns of the movement such as home and gender-determined spheres, motherhood, work, marriage, independence, and self-sufficiency and relates them to the transforming character of female identity at the time. The study focuses primarily on analyzing the expression of female historical desire through utopian genre and on explicating the contradictory nature of utopian production.

American Choral Music in Late 19th Century New Haven: The Gounod and New Haven Oratorio Societies

Description: This study examines two of the smaller American choral societies that together existed for just over 30 years, 1888 to 1919: The Gounod and New Haven Oratorio Societies of New Haven, Connecticut. These societies are important because, especially in the case of the New Haven Society, they were closely related to Yale University and the work of Horatio Parker. One must assume from the onset that the two choral groups examined in the following pages did not have the prominence of the many larger New England choral societies. However a more detailed knowledge about the struggles, successes, influence and leadership of two smaller societies illuminates a field of research in the history of American choral music that has been largely ignored.

The American Community College's Obligation to Democracy

Description: In this thesis, I address the dichotomy between liberal arts education and terminal vocational training in the American community college. The need is for reform in the community college in relation to philosophical instruction in order to empower citizens, support justice and create more sustainable communities. My call for reform involves a multicultural integration of philosophy into terminal/vocational programs as well as evolving the traditional liberal arts course to exist in a multicultural setting. Special attention is focused on liberating the oppressed, social and economic justice and philosophy of education.

The American Doctrine for the Use of Naval Gunfire in Support of Amphibious Landings: Myth vs. Reality in the Central Pacific of World War II.

Description: The United States Marine Corps and the United States Navy developed during the interwar period a doctrine that addressed the problems inherent in the substitution of naval gunfire for artillery support in an amphibious assault. The invasion of Betio Islet, Tarawa Atoll, in November of 1943 was the first test of this doctrine. It has been said many times since the war that the doctrine basically passed this test and that lessons learned at Tarawa increased the efficiency with which the Marine Corps and Navy applied the prewar doctrine during the rest of the war. An analysis of the planning and execution of naval bombardments in the Central Pacific Campaign, after the invasion of the Gilberts, does not support this claim. This analysis leads the researcher to three conclusions. First, the Japanese developed defenses against many of the effects of the gunfire support doctrine that blunted much of the force of American firepower. American planners were slow to recognize the implications of these changes and, consequently, were slow to react to them. Second, many naval commanders responsible for providing naval gunfire support for Central Pacific operations still equated tonnage of ordnance to effectiveness of bombardment, regardless of their frequent references to "the lessons of Tarawa." Finally, strategic concerns and outright ignorance played a large part in determining the use of naval gunfire, the first taking precedence over the "lessons" and the second leading to the ignoring of the "lessons" all together.

The American Trumpet Sonata in the 1950s: An Analytical and Sociohistorical Discussion of Trumpet Sonatas by George Antheil, Kent Kennan, Halsey Stevens, and Burnet Tuthill.

Description: The trumpet, or some ancestral form of the trumpet, has existed nearly as long as civilization itself. Despite its long history, however, the trumpet's solo repertoire remained limited and relatively unvaried until the second half of the twentieth century. Like most music, the American trumpet sonatas from the 1950s are a reflection of the culture and history surrounding their composition. The purpose of this research is to show how the trumpet sonatas by George Antheil, Kent Kennan, Halsey Stevens, and Burnet Tuthill are both distinctly American and unmistakably from the 1950s. The post-war era in America is often viewed as a time of unbridled optimism stemming from economic prosperity and the nation's military and industrial supremacy. The decade of the 1950s is often viewed today as a simpler, happier time in America's history. The trumpet sonatas of this era reflect this primarily in their ebullient rhythms and brilliant, often heroic melodies. However, darker characteristics of the decade (the rise of communism, for example) also make veiled appearances in these four sonatas. After an overview of the social and musical trends of the decade, the central chapter of the work delineates formal, thematic, and tonal structures of each of the four sonatas and their constituent movements. Highlighted throughout the analyses are similarities between the pieces, especially intervallic structures, motivic rhythms, and melodic construction. The final chapter discusses these similarities further and integrates them into 1950s American history and culture.

Amon Carter: The Founder of Modern Fort Worth, 1930-1955

Description: From 1930 to 1955, Amon Carter, publisher of the Fort Worth Star-Telegram, exerted his power to create modern Fort Worth. Carter used his stature as the publisher of the city's major newspaper to build a modern city out of this livestock center. Between 1930 and 1955, Carter lobbied successfully for New Deal funds for Fort Worth, persuaded Consolidated Aircraft to build an airplane plant in the city, and convinced Burlington Railways to stay in the city. He also labored unsuccessfully to have the Trinity River Canal built and to secure a General Motors plant for Fort Worth. These efforts demonstrate that Carter was indeed the founder of modern Fort Worth.

Amorphization and De-vitrification in Immiscible Copper-Niobium Alloy Thin Films

Description: While amorphous phases have been reported in immiscible alloy systems, there is still some controversy regarding the reason for the stabilization of these unusual amorphous phases. Direct evidence of nanoscale phase separation within the amorphous phase forming in immiscible Cu-Nb alloy thin films using 3D atom probe tomography has been presented. This evidence clearly indicates that the nanoscale phase separation is responsible for the stabilization of the amorphous phase in such immiscible systems since it substantially reduces the free energy of the undercooled liquid (or amorphous) phase, below that of the competing supersaturated crystalline phases. The devitrification of the immiscible Cu-Nb thin film of composition Cu-45% Nb has been studied in detail with the discussion on the mechanism of phase transformation. The initial phase separation in the amorphous condition seems to play a vital role in the crystallization of the thin film. Detailed analysis has been done using X-ray diffraction, transmission electron microscopy and 3D atom probe tomography.
