41	Psalms, Hymns, and Commercial Songs: Tradition and Innovation in James Lyon's "Urania" La Spata, Adam 08 1900 (has links) This dissertation asserts the value of James Lyon's Urania to the field of American music history as a vital contribution to the development of music in the British colonies prior to the War for Independence. While previous scholarship acknowledges Urania's importance as the first publication in America to contain music by a native-born composer, this study argues that its subscription list and selection of anthems (both of which were new to the field of American music publishing) contribute to the status this compilation is due. The confluence of the English chapel tradition and American singing school tradition contributes to the theological universality and accessibility of its twelve anthems. An introductory chapter discusses the secondary literature upon which this study is based - notably that of Oscar Sonneck and Richard Crawford - and posits applications for the idea presented herein beyond the field of musicology. Chapter 2 provides biographical information on James Lyon and contextualizes Urania within the broader framework of the English chapel tradition and the American singing-school tradition. Chapter 3 discusses the marketability of music in colonial America and explores the biographies of the subscribers to Urania using modern databases. Chapter 4 concerns the confluence of music and sacred text by placing Urania as a spiritual and cultural descendant of the theological universality preached during the Great Awakening. It concludes with an analysis of the anthems, taking into account both text and music. Chapter 5 concludes the study by showing how Urania affected music in the generations after its publication. My dissertation concludes with four appendices. Appendix A is an annotated list of Lyon's subscribers. Appendix B parses out basic information on the anthems, notably the texts. Appendices C and D provide critical notes and editions of the anthems, respectively.

42	Searching for Songs of the People: The Ideology of the Composers' Collective and Its Musical Implications Chaplin-Kyzer, Abigail 05 1900 (has links) The Composers' Collective, founded by leftist composers in 1932 New York City, sought to create proletarian music that avoided the "bourgeois" traditions of the past and functioned as a vehicle to engage Americans in political dialogue. The Collective aimed to understand how the modern composer became isolated from his public, and discussions on the relationship between music and society pervade the radical writings of Marc Blitzstein, Charles Seeger, and Elie Siegmeister, three of the organization's most vocal members. This new proletarian music juxtaposed revolutionary text with avant-garde musical idioms that were incorporated in increasingly greater quantities; thus, composers progressively acclimated the listener to the dissonance of modern music, a distinctive sound that the Collective hoped would become associated with revolutionary ideals. The mass songs of the two Workers' Song Books published by the Collective, illustrate the transitional phase of the musical implementation of their ideology. In contrast, a case study of the song "Chinaman! Laundryman!" by Ruth Crawford Seeger, a fringe member of the Collective, suggests that this song belongs within the final stage of proletarian music, where the text and highly modernist music seamlessly interact to create what Charles Seeger called an "art-product of the highest type."

43	<b>Closed Vessel Burning Rate Measurements of Composite Propellants Using Microwave Interferometry</b> Shane A Oatman (18396357) 17 April 2024 (has links) <p dir="ltr">Burning rate as a function of pressure is one of the primary evaluation metrics of solid propellants. Most solid propellant burning rate measurements are made at a nearly constant pressure using a variety of measurement approaches. This type of burning rate data is highly discretized and requires many tests to accurately determine the burning rate response to pressure. It would be moreefficient to measure burning rate dynamically as pressures are varied. Techniques used to make transient burning rate measurements are reviewed briefly and initial results using a microwave interferometry (MI) technique are presented. The MI method used in tandem with a closed bomb enables nearly continuous measurement of burning rates for self-pressurizing burns, capturing burning rate data over a wide range of pressures. This approach is especially useful for characterization of propellants with complex burning behaviors (e.g., slope breaks or mesa burning). The burning rates of three research propellants were characterized over a pressure range of 0.101-24.14 MPa (14-3500 psi). One research propellant exhibited a slope break at a pressure of 6.63 MPa (960 psi). Using MI in a closed pressure vessel, 14 propellant strand burns resulted in a nearly continuous burning rate curve over a pressure range of 0.41-24.13MPa (60-3500psi) that reasonably matched conventional burning rate measurements. The development of this technique provides an opportunity to quickly characterize the burning rate curve of solid propellants with greater fidelity and efficiency than traditional quasi-static pressure testing techniques.</p> microwave interferometry burning rate Burning rate interferometry Spatially Composite propellants slope break exponent break lab scale propellant testing crawford bomb closed bomb pressure vessel
44	Elementary school children’s acceptance and use of digital school libraries at Crawford Preparatory Pretoria School in Gauteng Province, South Africa Moyo, Sharon 05 1900 (has links) The use of the digital school library depends on many factors, including end-users‘ acceptance. The issue of designing information systems that will be used appropriately is growing and thus user acceptance of new technology is now receiving much attention by researchers. Without acceptance, discretionary users will seek alternatives, while even dedicated users will most likely manifest dissatisfaction, negating many, if not all, the presumed benefits of the digital library. Whereas the traditional focus of digital libraries has drawn research on technological developments, there is a call for user-focused research. This study sought to identify the dynamics of elementary children‘s (11- to 13- year olds) decision-making in the context of accepting or resisting making use of digital school libraries at Crawford Preparatory Pretoria School in Gauteng. To be accepted, the digital library must satisfy basic usability requirements and be perceived as useful by the children. The constructs of the Technology Acceptance Model, perceived ease of use and perceived usefulness were used to generate an understanding of acceptance of the digital school libraries. The study adopted a quantitative case study research approach to compare the empirical data and the TAM theory. Data triangulation of a wide range of data collection methods, including observation, questionnaires, focus groups and tasks given to the children to work on using the International Children‘s Digital Library was analysed. The findings revealed that, just like adults, children make decisions regarding accepting and using the digital school library based on how easy it is to use and how relevant it is to their needs. The study recommends that software designers, teachers and librarians work with the children when designing digital school libraries to ensure that their acceptance factors are taken into consideration when designing for them. / Information Science / M.

46	Overeating, Obesity, and Weakness of the Will Sommers, Jennifer Heidrun 28 August 2015 (has links) The philosophical literature on akrasia and/or weakness of the will tends to focus on individual actions, removed from their wider socio-political context. This is problematic because actions, when removed from their wider context, can seem absurd or irrational when they may, in fact, be completely rational or, at least, coherent. Much of akrasia's apparent mystery or absurdity is eliminated when people's behaviours are considered within their cultural and political context. I apply theories from the social and behavioural sciences to a particular behaviour in order to show where the philosophical literature on akrasia and/or weakness of the will is insightful and where it is lacking. The problem used as the basis for my analysis is obesity caused by overeating. On the whole, I conclude that our intuitions about agency are unreliable, that we may have good reasons to overeat and/or neglect our health, and that willpower is, to some degree, a matter of luck. / Graduate / 0630 / 0573 / 0422 / felshereeno@aol.com akrasia action theory addiction agency Alison McIntyre applied ethics Bernard Williams body studies Bourdieu Cartesian dualism Christine Korsgaard compulsion continence deviance diet Distinction Donald Davidson dualism externalism incontinence inequality internalism intuition Irving K.
