This is an historical and critical study of the discipline of musicology. The study is divided into two major sections: a retrospective of musicology, and a critique of musicology. The retrospective is an historical-chronological survey of selected writers on music beginning with the ancient Greeks and ending at the close of the 19th century. The writings of these musicologists are scrutinized for content, methodology and continuity of ideas and concepts. / The critical part of the study is in the Kantian mode using a methodology derived from the phenomenology of Edmund Husserl. This part is a critical study of the sources, scope and limits of musicology as delineated in the retrospective and as found in the 20th century through phenomenological critique of the sub-regions within the discipline. From the critical study it is demonstrated that the field of musicology exhibits one fundamental characteristic: an attempt to be a systematic study of musical phenomena. Within this field there are many sub-regions which share the above-mentioned common musicological characteristic but which are different from each other in essential ways; these differentia are fully described in the critique. / Finally, the study may be read in two ways: as a critique of musicology as described above; or as an example of applied phenomenology. / Source: Dissertation Abstracts International, Volume: 45-09, Section: A, page: 2898. / Thesis (Ph.D.)--The Florida State University, 1984.

The sacred and the profane perpetuate life in a dialectical fashion for it is by virtue of one that the other is defined and recognized. Flannery O'Connor establishes a fictional dichotomy between the sacred and the profane. In exploring the tragic sense of the human condition, O'Connor illustrates the need for grace which manifests itself in the grotesque, the violent and the absurd. Like the Old Testament prophets, O'Connor's club-footed freaks, martyred mothers and Christ-obsessed Bible thumpers carry the burden of Truth--the penetrating intrusion of the Sacred into a world that proudly proclaims the autonomy of the Profane. While the elements of the profane may parallel O'Connor's use of the grotesque, its ultimate purpose is not to shock and horrify the reader but to heighten the mystery of Grace. / Source: Dissertation Abstracts International, Volume: 45-06, Section: A, page: 1780. / Thesis (Ph.D.)--The Florida State University, 1984.

Giambattista Vico is slowly emerging from too often convenient dismissal as an unsystematic and obscure philosopher to command more considered and serious attention from scholars whose interests range from sociology to literary criticism. This dissertation attempts to interpret Vico's major ideas through the insights of the sociology of knowledge and psychoanalysis. This study focuses especially on Vico's idea of Providence as a mechanism of social ordering and social preservation. / After introductory remarks on Vico's thought, the First Chapter deals with Vico's biographical data. The Second Chapter attempts to explicate Vico's idea on Religion and Providence as they function in the genesis of human self-consciousness and human social order. The Third Chapter elaborates, specifically, Vico's ideas of Providence as a binding force that moves man toward preservation and social order. In the Fourth Chapter the notion of Providence is applied to human institutions. The idea of Providence is subsequently applied to history (Chapter Five). A Conclusion attempts to re-evaluate Vichian studies in the light of the proposed sociological and psychological insights. / Source: Dissertation Abstracts International, Volume: 45-09, Section: A, page: 2897. / Thesis (Ph.D.)--The Florida State University, 1984.

Counterflow Heat Transfer in He II Contained in Porous Media

Unknown Date (has links)
This dissertation presents a study of steady He II (superfluid helium) counter flow heat transfer in porous media. Porous insulation were suggested as potential alternatives to conventional fully impregnated insulations in superconducting magnet technology. Superconducting magnets are usually cooled with He II. Use of porous insulation requires thus a good knowledge of the behavior of He II within porous materials, when set in motion or exposed to a heat source. The present work was focused on the design of an apparatus capable of performing both steady and transient counterflow measurements in He II saturating a porous material with a geometry similar to potential candidate porous insulations. Those will most likely be composed of tapes of pre-impregnated woven ceramic fibers, forming a highly anisotropic compound, with a wide pore size distribution. The samples were provided by Composite Technology Development Inc. and are circular pellets (3.08 mm thick and 28.58 mm in diameter) of 20 compressed layers of pre-impregnated woven magnet insulation. The porous material was carefully characterized prior to experimental runs in He II. The samples exhibit a porosity and a permeability of respectively 20+-1% and 0.95x10^-14 m^2 for water measurements. The woven fiber rovings, composing the insulation, were found to be 0.04 mm^2 of average cross sectional area with fibers of average diameter of 10.6 micron. The He II experimental apparatus is composed of a vacuum insulated open channel whose top extremity is closed to a Minco heater. The temperature differences and pressure drops across the porous plug were measured by two Lakeshore barechip Cernox 1050BC thermometers and a Validyne DP10-20 differential pressure sensor. Applied heat fluxes ranged up to 0.5 kW/m^2 of sample cross section. Steady temperature differences, up to 570 mK, and pressure drops, up to 1800 Pa (limit of the sensor), measurements were performed at bath temperatures ranging from 1.6 to 2.1 K. In the low heat flux regime, the permeability data corroborate room temperature measurements. In the high heat flux regime however, we show evidence of the failure of previous models based on the inclusion of the tortuosity in the turbulent equation. We propose to include a constriction factor denoting an average maximum change in cross section in the heat path in addition to the increased path length denoted by the tortuosity. In the turbulent regime, this constriction factor is predominant as it enters in the model with a cubic power. Measurements of the critical characteristics, corresponding to the point of transition from the laminar regime, where Darcy law is applicable to the non-linear regime, where the heat flux adopts its characteristic cubic relationship, corresponding to the appearance of turbulence within He II are also reported. We obtained critical heat fluxes ranging from 20 to 70 W/m^2, Reynolds numbers of 0.5 to 4 and normal fluid velocities from 0.5 to 2.5 mm/s, varying with bath temperature. To confirm the room temperature measurements of permeability, we also conducted a forced flow experiment. Unfortunately, the flow range covered is outside of the laminar regime and does not permit an accurate estimation of the permeability. The results are however favorably comparable to earlier data recorded in the turbulent regime in similar flow conditions but with very different materials. / A Dissertation submitted to the Department of Mechanical Engineering in partial fulfllment of the requirements for the degree of Doctor of Philosophy. / Degree Awarded: Spring Semester, 2010. / Date of Defense: November 12, 2009. / Cryogenics, Heat Transfer, Magnet Insulation, Porous Media, Counterflow, Superfluid Helium / Includes bibliographical references. / Steven W.

In the southernmost Appalachians, bimodal volcanics of Pumpkinvine Creek Formation (PCF) and its proposed equivalent, the Hillabee Greenstone (HG) have indistinguishable ages (~460 Ma) and trace element-REE pattern similar to an arc/back-arc type setting. Eplison 143Nd values of felsic members of the HG and PCF indicate involvement of Grenville crust during petrogenesis. U-Pb dates (900-1500)Ma of detrital zircons in PCF meta-sandstone cluster around 1100Ma. Nd-model ages of the Ashland-Wedowee Supergroup metasediments range between 943-1439 Ma and cluster around 1000 Ma. Rb-Sr whole rock and U-Pb zircon dates of the Mulberry Rock Gneiss also demonstrate an Ordovician age (~460 Ma). It is concluded that the PCF-HG arc formed on the Laurentian continental margin on Ashland-Wedowee sediments during Ordovician and remained outboard of the continent until final closure during Alleghenian orogeny. Geochronological investigations of the Tres Piedras Granite of northcentral New Mexico have revealed a sharp discordancy between Rb-Sr whole-rock and U-Pb zircon ages. Analyses of fifty individual zircons (most concordant) by LA-MS-ICPMS yield a ~1730 Ma magmatic crystallization age. Rb-Sr whole-rock isochron ages from separate localities are 1490+/-20 Ma and 1497+/-42 Ma. Sphene/whole-rock/biotite isochron ages and initial 87Sr/86Sr ratios from separate localities are indistinguishable from those of whole-rock isochrons. In both cases feldspar plots above the isochrons and appeared to be an open system as evidenced by 4% difference in 87Sr/86Sr in the core and rim of feldspar. Taken altogether, these data are interpreted to reflect a large (kilometer) scale redistribution and rehomogenization of strontium isotopes during an independently, well-documented metamorphic event in the region. The geochemical character of the Kutch volcanics, northwest of Deccan Traps, India, have been investigated in order the magma's origin. Sr-Nd-Pb isotopic ratios and trace element patterns identifies three end members: Reunion plume-type alkali basalts, Mahabaleshwar-type alkali basalts and crustally contaminated tholeiites. The first type of alkali basalts that can be generated by very low degree of partial melting (1.6-1.8%) of Reunion plume like source at garnet stability field; the tholeiites can be explained by crustal contamination of Indian-MORB like magma. High 207Pb/204Pb (15.61-15.83) ratio of the tholeiites agrees well with the Pb-isotopes of local Archean crust. / A Dissertation submitted to the Department of Geological Sciences in partial fulfillment of the requirements for the degree of Doctor of Philosophy. / Degree Awarded: Fall Semester, 2006. / Date of Defense: November 1, 2006. / Pumpkinvine Creek Formation, Back Arc Lavas, Isotopic Homogenization, Hillabee Greenstone, Kutch Volcanics / Includes bibliographical references. / A.

Husserl's Phenomenology and the Foundations of Natural Science develops a reading of Husserl's phenomenology as a response to the philosophical problems motivated by the metaphysics of early natural science; in particular, the problems which grew from the methodological distinction between a real objective world and the so-called "subjective" world in which we live. / Husserl's unfulfilled claim in the Ideas ((SECTION) 33) that the epoche and reductions will be developed in a graded series is taken to heart, and this graded series is developed in terms of its still inchoate appearance in the Crisis. Epoche is read as the act which motivates the event of reduction and the first act of epoche is read as the suspension of the objective scientific world, i.e., "Nature," while reduction(,1) is read as the disclosure of the "life-world," or, as a return to the "things-themselves." The second act of epoche is read as a suspension of these "things of the world" and reduction(,2) is read as reduction to the appearances. / The role of constitutional analyses in Husserl's phenomenology is then developed as the third requisite step in Husserl's attempt to provide phenomenological foundations for the natural sciences. It is shown that epoche without reduction is blind, while reduction without constitution is mute. Only with the well-connected descriptions which are the constitutional analyses of the synthetic processes of consciousness, does the "constructive" work of phenomenology begin. Constitutional analyses of reduced experiences are argued (and shown) to provide the constructive/synthetic element via which the world of "life" and the world of natural science are regained--eventually, as phenomenologically grounded. / The dissertation concludes by summarizing phenomenology's role as a "meaning-restorative" to meaning-depleted sciences, and by defending Husserl's notion of "reduction." / Source: Dissertation Abstracts International, Volume: 44-06, Section: A, page: 1815. / Thesis (Ph.D.)--The Florida State University, 1983.

Writing Memory: The Latino Community and Continuity in the Writings of Julia Alvarez, Judith Ortiz Cofer, and Achy Obejas.

Unknown Date (has links)
This is a study of narratives of three women authors of Spanish Caribbean origin writing in English in the United States- Julia Alvarez, Judith Ortiz Cofer, and Achy Obejas. The investigation theorizes the function of memory in narratives, used to carve a collective ethnic identity of the specific Latino groups, in order to maintain a continuity of the displaced community. The texts targets the second generation immigrants who find themselves in conflict with a society where they are at the margins because of differences from the dominant norms of society. Marginalization is countered by the creation of a link to the continuing cultures and establishing a collective identity, molded out of the collective memories of the people of the community. The texts look at three kinds of memories, namely the historical, the autobiographical, and the ethnic memory, which are instrumental in the construction of a collective, at different levels- the national, the personal, and the cultural. The textual narrative as an implement to circulate the notion of a common bond between the author, the narrator, the text, and the reader allows for the emergence of the Latina voice, as the subject through the female narrator and the characters, indicative of a social force resisting marginalization, and telling her history in her own terms. / A Dissertation submitted to the Department of Modern Languages and Linguistics in partial fulfillment of the requirements for the degree of Doctor of Philosophy.. / Degree Awarded: Fall Semester, 2005. / Date of Defense: October 19, 2005. / Caribbean Latina Writers, US Latino Literature / Includes bibliographical references. / Roberto G.

A study in the theology of Paul Tillich as it relates to the experience of worship and preaching in particular. As a fundamental point-of-departure, attention is given to the sacramental-prophetic dialectic from which preaching springs. Then, in order to contextualize the sermon more clearly, Tillich's understanding of the dynamics of worship is delineated. A further narrowing of focus brings the preacher and his task into clear relief, whereupon an analysis of Tillich's personal philosophy and practice of ministry follows. Lastly, the Tillichian sermon is considered as the critical point where theology meets human need. / The major thrust of this dissertation may be reduced to a thesis statement: Paul Tillich's vocation as a Christian apologist is demonstrated in his preaching. It is not enough to label him as a "philosophical theologian," as a "Christian humanist" or an "existentialist." He was an apologist at the core of his being, and as such he had a passion for communicating the Christian faith to the outsider. Consequently, his sermons provide a good introduction to his theology, an important body of literature with abiding value and a model for preaching. / Source: Dissertation Abstracts International, Volume: 44-09, Section: A, page: 2794. / Thesis (Ph.D.)--The Florida State University, 1983.

Southern Baptists have grown from a membership of 365,346 to 14 million since their organization in 1845. Yet they are a silent people on many issues. Patriots who supported the colonists during the American Revolutionary War, hawks in matters of national defense, crusaders in matters relating to personal morality, they have been largely silent on many social actions which excite other denominations. They led no peace marches during the sixties, waved no banners for women's rights in the seventies, and remain aloof from the liberation theologies of the eighties. Whence came this strange reticence to become involved in certain kinds of social political action? / The answer to this question comes partly from the historical development of the Baptists in early seventeenth-century England where, as a result of religious persecution, they began to contend for the separation of church and state. Part of the answer arises from the development of the individualism necessary for survival on the American frontier. However, the thesis of this dissertation contends that the answer mainly comes from a theology which reflects individualism. Beginning with the concept of a God who demands personal righteousness and providing with a view of a depraved humanity in need of an individual, ontological change based on the substitutionary death of Christ and effected by the Holy Spirit in those who repent of their sins and trust Christ for personal salvation, Southern Baptists believe social change results when redeemed people apply Christian principles in society. Consequently, the local church qua church studiously avoids involvement in economic, political, and social issues except as these derive from, or impinge upon, personal righteousness. / Source: Dissertation Abstracts International, Volume: 46-01, Section: A, page: 0173. / Thesis (Ph.D.)--The Florida State University, 1984.

A study of relativism structured around the fact that there are differences between arguing for a general thesis of relativism and arguing for a limited thesis applicable to a restricted domain of thought and life. Differences between relativism and its chief competitors, skepticism and reductionism, are discussed in detail. Relativism in contemporary debate often turns out to be skepticism or reductionism instead. The discussion illuminates what is required for genuine relativism whether general or limited. It makes plain that there are both intellectual and practical consequences involved in whether one is relativist, skeptic, or reductionist as one opposes alleged absolutisms. / The first two chapters examine problems in interpreting the general relativism of Protagoras. The argument, going back to the Theaetetus, which is meant to show that relativism is self-contradictory is discussed. Limited forms of relativism easily escape the argument. A general relativist thesis is made implausible by the argument, but is not necessarily defeated. / In chapter three tools sharpened in the study of Protagoras are applied to contemporary debates about general relativism in linguistics, anthropology, science, and philosophy. I find many drawing unwarranted relativist conclusions on the basis of skeptical arguments. In chapter four the same tools are applied to discussions of more limited relativist theses in philosophy, ethics and science. Here confusions arise in distinguishing between relativism and reductionism. / In the conclusion I review how general relativism is implausible and is not supported by most of the contemporary arguments offered for it. Limited relativist theses, in philosophy, ethics, and science, are seen to be more plausible. I suggest that a moderate skepticism should be carefully distinguished from both relativism and reductionism, and I offer seasons why moderate skepticism may be the most fruitful response to absolutisms. This is illustrated by an examination of important practical differences that arise when the problem of public policy about abortion is approached from the different perspectives of relativism, skepticism, and reductionism. / Source: Dissertation Abstracts International, Volume: 47-12, Section: A, page: 4409. / Thesis (Ph.D.)--The Florida State University, 1986.
