The Rhetoric Of Writing: A Rhetorical Analysis of Modern Writing Memoirs

Illich, Lindsay P. 14 January 2010 (has links)
This dissertation analyzes concepts of the writing self in works about writing by professional creative writers (writers, poets, and essayists). Through a rhetorical analysis of these texts, I observe that writers view the writing self as a complex structure that is fully conscious as a rhetorical agent, an embodied self that interacts with the world and actively chooses linguistic representations of that experience, and maintains a concept of self that is subject to influences which the writers do not fully understand (such as inspiration and insight). The discourse used by writers to describe their writing processes challenges recent critiques of expressionism and the model of social construction that pervades contemporary composition scholarship. Chapter II examines Virginia Woolf's use of the central metaphor for invention in A Room of One's Own, a river, which sharply calls into question a unified view of the self which is central to critiques of expressivism by composition scholars. Woolf's concept of invention requires a negation of the self and harmony with nature (widely conceived as the entire world, including texts). Chapter III, an analysis of two writing memoirs by contemporary professional creative writers, Annie Dillard's The Writing Life and Donald Hall's Life Work, finds that Dillard and Hall use metaphors that establish freedom (rhetorical agency) and bodily presence as primary characteristics of their writing processes. Chapter IV, an analysis of two collections of essays about writing by professional creative writers, argues that the writers' use of metaphors of inspiration and instrumental metaphors creates a concept of the writing self that maintains a sense of writerly control (rhetorical agency) alternating with a sense of a diminished control; ultimately, the two concepts coexist in the minds of the writers. Chapter V proposes that the rhetorical situation of the contemporary composition classroom affects students' creativity adversely. The chapter also suggests further analyses of writing memoirs can provide new ways of understanding writing processes (as opposed to one writing process model) and therefore contribute substantially to composition scholarship and pedagogy.

Characterization of AlxGa1-xN/GaN grown on GaN-template by plasma-assisted MBE

Chen, Yu-chih 01 July 2009 (has links)
In order to develop high speed photo-electronic device, first, we grew one layer of GaN by MOPVE to decline lattice mismatch. Then we used PA-MBE to grow AlxGa1-xN/GaN heterostructure III-V semiconductor. Via changing the content of aluminum, we can confer the characteristic of these samples. In these samples, we controlled the content of aluminum by changing the vapor of aluminum. And then we used X-ray diffraction, SEM, AFM, low temperature Hall measurement and SdH to study the characteristic of these samples. Throughout X-ray diffraction, the aluminum content x are 1.76%, 2.3%, 14.33%, 22.03% and 37.26%. Due to (004) AlGaN Rocking Curve F.W.H.M. are only 300 arcsec, the quality of the five samples are extraordinary. In addition, SEM and AFM measurement indicate that this series samples¡¦ interface are very smooth, and the roughest sample is only 2nm. It can make sure that samples were grown in mode of two-dimensional (2D). With low temperature Hall measurement, we can find out the Coulomb scattering which is from the defect are very small in the sample A, B, C, D. And the mobility of this series samples are very high, the highest mobility is sample A at 8K which is 19593 cm2/Vs. We can observe the oscillation of the sample C, D obviously in SdH measurement indicate that the 2DEG is confined in the potential well.

Study of AlGaN/GaN quantum structure fabricated by Focus ion beam

Chang, Yung-Shi 28 July 2009 (has links)
We have observed a large spin-splitting in device made of AlxGa1-xN/GaN quantum wires. Based on this observation, we proposed a new spintronic application, the spin-hall quantum-ring interferometer, by the spin-Hall effect, Rashba and Dresselhaus effects. This device we use the ICP Etch System to etch the contact pattern, and then use the Multi-Target Sputter to deposit the protecting layer, and then use the E-Beam Evaporator to make the contact. Finally, using the Focus Ion Beam, we fabricate the quantum-ring and gate successfully. This thesis is focused on discussing the design of the fabrication and try to solve the problem in order to be able to detect the signal of the quantum-ring interferometer at low temperature and high magnetic condition.

Mesure des champs magnétiques alternatifs et continus dans les plasmas naturels : développement d'un magnétomètre searchcoil à bande étendue.

Leroy, Paul 01 February 2007 (has links) (PDF)
Le CETP a une expertise reconnue depuis de nombreuses années dans le domaine des capteurs de champs magnétiques alternatifs en environnement spatial (plasmas naturels et magnétosphère). Ces magnétomètres nommés searchcoils, sont constitués d'un noyau en matériau ferromagnétique sur lequel est bobiné un fil de cuivre. De récentes améliorations ont été apportées aux searchcoils en travaillant sur la forme de leur noyau magnétique : des instruments plus petits et plus légers, à sensibilité égale, ont pu être réalisés pour la mission multisatellite THEMIS par exemple. Par principe, le searchcoil ne permet pas de mesurer les champs magnétiques continus. Dans les expériences spatiales, cette mesure est confiée au magnétomètre fluxgate. Les capteurs de champs magnétiques issus des technologies employées pour la microélectronique (dépôts en couches minces, semi-conducteurs), tels que les capteurs à effet Hall ou les magnétorésistances, n'ont pas des sensibilités comparables à celles des fluuxgates, et ce, à au moins trois ordres de grandeur près ! Le point de départ de notre travail est d'ajoindre au searchcoil un capteur de champ magnétique continu issu de la microélectronique en utilisant le noyau magnétique pour améliorer sa sensibilité et tenter d'atteindre les performances des fluxgates. Ce nouvel instrument aurait pour intérêt de proposer une mesure redondante sur le champ magnétique continu, en utilisant une technologie différente du fluxgate, sans augmentation de l'encombrement puisque le searchcoil est peu modifié par l'introduction du microcapteur.
