La réception conjointe de l'"Avesta" et du "Livre des Rois" en France (1771-1914) / The joint reception of "Avesta" and "The Shahnameh" in France (1771-1914)

Tavakoli, Helia 23 November 2018 (has links)
Consacrée à la réception en France de deux grands textes canoniques de la littérature persane, l’Avesta et le Shâh-Nâmeh (Livre des rois) de Ferdowsi, la thèse examine les circonstances de la publication de la traduction de l’Avesta par Anquetil-Duperron et les travaux critiques de William Jones sur cette entreprise, et analyse le débat entre ces deux chercheurs, et notamment l’implication de Voltaire dans cette vaste controverse et la contribution de Louis Langlès, qui a le premier révélé aux Français l’œuvre de Ferdowsi en 1788. Ensuite, notre recherche repose principalement sur l’étude des échanges de vues et correspondances des hommes de lettres de la période révolutionnaire, napoléonienne et romantique par rapport aux deux œuvres. Elle examine la place que tient le Shâh-Nâmeh dans le champ des études comparatistes, alors tout nouvellement défini en France par Jean-Jacques Ampère, et les discussions portant sur la valeur historique et poétique de l’œuvre dans le cadre de réflexions sur l’ancienneté et l’origine du monde. L’épopée persane intervient à plusieurs reprises dans les débats de la période concernant l’Antiquité, la chevalerie, et le genre même de l’épopée. Outre Ampère, Volney, Silvestre de Sacy et Sainte-Beuve sont les figures marquantes de cette étude ainsi que le rôle important joué par Mary Clarke et Helmina von Chézy. / Devoted to the reception in France of two great canonical texts of Persian literature, the Avesta and the Shâh-Nâmeh (Book of Kings) of Ferdowsi, the thesis examines the circumstances of the publication of the translation of the Avesta by Anquetil- Duperron and the critical works of William Jones on this company, and analyzes the debate between these two researchers, including the involvement of Voltaire in this vast controversy and the contribution of Louis Langles, who first revealed to the French the work of Ferdowsi in 1788. Next, our research is mainly based on the study of exchanges of views and correspondences of the men of letters of the revolutionary period, Napoleonic and romantic compared to the two works. It examines the place of Shâh-Nâmeh in the field of comparative studies, then newly defined in France by Jean-Jacques Ampère, and the discussions on the historical and poetic value of the work as part of reflections on antiquity and the origin of the world. The Persian epic is a part of the debates of antiquity, chivalry, and the genre of the epic. Besides Ampère, Volney, Silvestre de Sacy and Sainte-Beuve are the key figures of this study as well as the important role played by Mary Clarke and Helmina von Chézy.

School principal influence actions, climate, culture, and school performance

Unknown Date (has links)
This quantitative, non-experimental study was conducted to investigate the link between school principal influence actions, climate, culture, and school performance. Additionally, this study sought to determine if the influence of these variables or the relationship among them is altered by individual and/or institutional characteristics. The first phase of the study was conducted to determine whether or not the Customer Survey aligned to distinct dimensions. Two factors were identified: Staff Attitudes and Student Disruptions. The second part used regression to examine the relationships among four constructs and test the seven hypotheses. / Includes bibliography. / Dissertation (Ph.D.)--Florida Atlantic University, 2014. / FAU Electronic Theses and Dissertations Collection

Estudo do ponto invariante com a temperatura (ZTC) em SOI-FInFETS tensionados e radiados. / Study of zero temperature coefficient ZTC) on SOI-FinFETs strained and irradiated.

Nascimento, Vinicius Mesquita do 17 February 2017 (has links)
Este trabalho foi realizado tendo como objetivo o estudo do ponto invariante com a temperatura (ZTC - Zero Temperature Coefficient) para transistores com estrutura SOI FinFET em relação aos efeitos de tensionamento e radiação, através da utilização de dados experimentais e de um modelo analítico. Foram analisados primeiramente os parâmetros básicos de tensão de limiar e transcondutância, nos quais está baseado todo o modelo e verificado a influência dos efeitos do tensionamento e da radiação nos mesmos, para analisar o comportamento da tensão de porta no ponto ZTC em dispositivos do tipo n. Foram utilizados dispositivos com três dimensões de largura de aleta (fin) diferentes, 20nm, 120nm e 370nm e comprimento de canal de 150nm e de forma comparativa em dispositivos de 900nm, em quatro lâminas diferentes, sem/com tensionamento e/ou sem/com radiação. A tensão de limiar sofre grande influência do tensionamento, enquanto a radiação tem menor efeito na tensão de limiar na faixa estudada, passando a ter maiores significâncias nos dispositivos tensionados com maior largura de aleta. A transcondutância também sofre maior influência do efeito de tensionamento, sendo neste parâmetro a alteração pelo efeito da radiação muito menor. Contudo estes dois parâmetros geram outros dois parâmetros essenciais para análise do ZTC, que são obtidos através das suas variações em relação a temperatura. A variação da tensão de limiar em relação à temperatura e a degradação da transcondutância também pela temperatura (ou fator c: degradação da mobilidade pela temperatura), influenciam diretamente na eventual variação do ponto de ZTC com a temperatura. Quando estas influências são pequenas ou atuam de forma a compensarem-se mutuamente, resultam em valores de ZTC mais constantes com a temperatura. A tensão de limiar influência direta e proporcionalmente no valor da tensão de ZTC em amplitude, enquanto a degradação da mobilidade (transcondutância) atua mais na constância do ZTC com a temperatura. Com base nestes mesmos parâmetros e com ajustes necessários no modelo foram estudados dispositivos com as mesmas características físicas, porém, do tipo p, onde os resultados encontrados tiveram relação a característica de funcionamento deste outro tipo, ficando claro a inversão da significância dos efeitos quanto a variação da temperatura. O modelo simples e analítico utilizado para o estudo do ZTC foi validado para esta tecnologia, já que foi encontrado valores de erro entre valores experimentais e calculados com um máximo de 13% incluindo toda a faixa de temperatura e a utilização dos efeitos de radiação e tensionamento, tendo mostrado valores discrepantes somente para alguns casos de largura da aleta maiores, que mostraram ter uma pequena condução pela interface canal/óxido enterrado antes da condução na primeira interface, não prevista no modelo. / This work was performed with the aim of the study of the invariant point with temperature (called ZTC - Zero temperature Coefficient) for transistors made with SOI FinFET structure in relation to the mechanical stress and irradiation effects, through of the use of experimental data and an analytical model. Were first analyzed the basics parameters as threshold voltage and transconductance, in which all the model is based and was verified the influence of the mechanical stress and irradiation effects on these parameters, for analyze the gate voltage\'s behavior on ZTC point in n type devices. Were used devices with three different width fin dimensions, 20nm 120nm and 370nm and channel length of 150nm and in a comparative way with 900nm length devices, in four different waffles, with/without mechanical stress and/or with/without irradiation. The threshold voltage suffers big influence from stress, while the irradiation has less effect on the threshold voltage in the studied band, becoming to have more significance on the stressed devices with larger fin width. The transconductance also suffers more influence of the stress effect, being on this parameter the variation caused by irradiation effect smaller. However, these two parameters generate others two essentials parameters for the ZTC analysis, they are obtained through of the previous parameters variation by the temperature. The threshold voltage variation by the temperature and the tranconductance degradation by the temperature (or c factor: mobility degradation by the temperature), influence directly on the eventual variation of the ZTC point by the temperature. When these influences are small or act by the way to compensate mutually, result at ZTC values more constant with the temperature. The threshold voltage influence direct proportionality on the ZTC voltage\'s value at amplitude, while the mobility (transconductance) degradation act more on ZTC stability with the temperature. Based in these same parameters and with necessaries adjusts on the model, were studied devices with the same physic characteristics, but of the p type, where the founded results had relation with the work characteristics of this other type, becoming clear the inversion of significance of the effects by the temperature variation. The simple and analytical model used for the ZTC study was validated for this technology, since it was found error values between experimental data and calculated data with a maximum of 13%, shown discrepant values only for some cases of larger fin widths, that shown to have a small conduction by the channel/buried oxide interface before of the first interface\'s conduction, not previewed in the model.

The Ineuitabile of Honorius Augustodunensis: A Study in the Textures of early Twelfth-Century Augustinianisms

Hannam, Walter January 2013 (has links)
Thesis advisor: Steven F. Brown / Despite several centuries of scholarly activity, one of the most outstanding figures of the twelfth-century renaissance, Honorius Augustodunensis, remains an elusive figure. Almost nothing is known of his life--where he was born, where exactly he lived, or where he died. Yet in his own day, Honorius's considerable literary output was extremely popular, was copied in profusion, and housed in libraries across Europe. Unfortunately, most studies of Honorius's works have consisted of very general surveys that oversimplify his thought and present Honorius himself as a `simplistic' thinker. Based upon a new critical edition of the two surviving recensions of Honorius's dialogue, Inevitabile, this study seeks to redress this problem. After a careful review of the scholarly literature on the text, from 1552 to 1996, several passages from both redactions of the Ineuitabile are carefully analyzed to illustrate both the complexity of Honorius's use of his sources (auctores/auctoritates), and his masterful blending of literary allusion with dialectic, which is the foundation of his theological methodology. Finally, it is shown that the doctrine of predestination in the earliest recension of the Inevitabile, which has traditionally been labelled `Augustinian', is in fact based, in large measure, on the teachings of John Scottus Eriugena. This study seeks to change the way that Honorius's texts are read and interpreted, in the firm conviction that only by engaging with the intricacies of his sources and methodology, can his true achievement be understood and the purpose behind his vast corpus of writings be grasped. / Thesis (PhD) — Boston College, 2013. / Submitted to: Boston College.

Within High Schools - - Influences on Retention among the Indigenous People of Northeast India

Pudussery, Paul Chacko January 2009 (has links)
Thesis advisor: Robert J. Starratt / A qualitative case study of three high schools was conducted to identify and profile school practices employed in educating a traditionally low-achieving subpopulation in northeast India. By the considerably higher than average retention and graduation rates among their students who come from indigenous tribal communities, these schools stand out as effective. The study was centered on the following research questions: 1) What were the teaching practices that characterize three high schools with successful records of graduating (upwards of 100%) indigenous Northeast India tribal students? 2) How were these successful schools affected by the school leadership? A body of related literature provided the theoretical rationale and informed the researcher in collecting data, doing analysis, and processing interpretation. The researcher reviewed specific categories of literature focused on the following: dropout influences, effective teaching practices, school leadership, indigenous tribal life contexts, spirituality, and worldview of the peoples of Northeast India. The findings indicated that these three schools with low dropout rates reflected authentic and effective teaching practices that were student-friendly and based on a coherent mix of various principles of learning, instructional strategies, classroom management, and the personal dedication of the teaching faculties. Furthermore, the schools tried to create an atmosphere of social connectedness and community, based on the values of the indigenous people of that area. The school leadership was proactive in an effort to sustain the sense of community through a variety of school activities and cooperation with parents. The researcher found that the ethos of the schools motivated students to focus on their studies in view of a better economic future. A contextualized pedagogy that took into account the background and learning styles of a wide variety of students helped the students to focus on their learning in the various academic disciplines. Pedagogical practices that promoted academic achievement in concert with indigenous values sustained the interest of the students and moved them to actively involve themselves in the life of the school. The leadership provided the necessary vision and direction to make the objectives and goals of the school understood and obtainable. The visible presence of the principal and his/her affirming interaction also helped to maintain the motivation of the community on all levels of operation. The findings of this research have implications for educational practice, policy, teacher preparation and school leadership in the context of rural India. / Thesis (PhD) — Boston College, 2009. / Submitted to: Boston College.

Stendhal, Shakespeare et La Chartreuse de Parme / Stendhal, Shakespeare and La Chartreuse de Parme

Breffi, Ferdinand 11 May 2019 (has links)
La Chartreuse de Parme est marquée par des matériaux « shakespeariens » recueillis par Stendhal, tout au long de sa pratique des pièces du dramaturge et de leurs multiples remodelages dans les arts. De quel(s) Shakespeare s’agit-il, entre 1800 et 1840 ? Faut-il s’atteler à celui traduit par Pierre Letourneur, à celui transmis par des réécritures parfois infidèles, ou au Shakespeare dans le texte, lu plus tardivement mais avec précision par Stendhal ? Ou à un Shakespeare mythique, construit tout au long de la vie intellectuelle de Stendhal ? Comment ces « Shakespeare » fonctionnent-ils dans le paysage intime du romancier ? Faut-il s’en tenir à l’auteur de 1838 ? Comment articuler ce Stendhal du crépuscule, avec celui de l’aube, un jeune Henri Beyle qui cherche à copier Shakespeare, dans son rêve de création théâtrale ? Comment, dans le texte du roman, s’interroger sur la présence préalable de l’auteur de pamphlets, qui, entre 1818 et 1825, affirme à travers le nom de Shakespeare le modèle d’une liberté esthétique qui manque à Paris, où étouffent les idées nouvelles ? Quelles conséquences l’imaginaire shakespearien de Stendhal a-t-il eu sur le texte de La Chartreuse de Parme ? Si le Stendhal de l’accomplissement chartreux recouvre les phases multiples de la construction de son imaginaire le plus intime, et si son innutrition shakespearienne est constituée par la démultiplication des matériaux shakespeariens qu’il rencontre et dont il se saisit constamment et pleinement, la question se pose, massive : comment lire, dans l’écriture de La Chartreuse de Parme les traces, les échos et les interactions des pièces de Shakespeare ? / La Chartreuse de Parme is marked by Shakespearean elements collected by Stendhal in his study of the playwright and his many imitations in the arts. But which Shakespeare(s) is it, between 1800 and 1840? Should we focus on the one translated by Pierre Letourneur, sometimes approximately, or should we focus on Shakespeare read in the original by Stendhal? Or even, on a mythical Shakespeare, constructed by Stendhal throughout his life? What part do these "Shakespeares" play in the intimate thoughts of the writer? Should we limit ourselves to the writer of 1838? How to reconcile the Stendhal of the twilight, with the one of the dawn, when a young Henri Beyle tried to imitate Shakespeare, in his dream of playwriting? How are we to take into account the presence, in the novel, of the pamphlet writer, who, from 1818 to 1825, uses Shakespeare’s name in order to propose an aesthetic freedom of which Paris is notably lacking? How much influence did the world of Shakespeare, as it was perceived by Stendhal, have on the text of La Chartreuse de Parme? In La Chartreuse de Parme, Stendhal uncovers the full extent of his imaginary world. His Shakespeare is made of the many Shakespearean materials he has come across, and he uses them without restraint. Then, the question is raised: how should one read, in La Chartreuse de Parme, the traces, echoes and interplays of Shakespeare's plays?

Caractérisation de la cinématique du genou : identifier les effets de différents paramètres sur la cinématique du genou en utilisant la modélisation / Knee kinematic characterization : 3D rigid body model : characterization of parameters effects on knee kinematics

Geais, Laurent 04 October 2011 (has links)
La cinématique de l’articulation du genou est complexe. Elle est déterminée par des paramètres géométriques et des paramètres mécaniques. Les paramètres géométriques sont principalement définis par la géométrie des os, des surfaces articulaires et par les insertions des différents tissus mous. Les paramètres mécaniques sont définis par les caractéristiques des tissus mous exprimés par les lois qui relient les distances entre leurs insertions et les efforts qu’ils génèrent. Les muscles, tendons et ligaments sont caractérisés par leur constante de raideur et leur pré-tension à une position donnée de l’articulation du genou : l’extension totale. Cette thèse analyse à l’aide d’un modèle multi-corps rigides le comportement de l’articulation du genou. La première partie de la thèse décrit la constitution du modèle. La seconde partie positionne le modèle dans des conditions aux limites. La troisième partie présente les résultats du modèle et les compare à différentes publications de la bibliographie. La quatrième et dernière partie fait varier les différents paramètres mécaniques et quantifie leur influence sur la cinématique du genou. Une synthèse des résultats permet de mettre en évidence les paramètres les plus influents sur la rotation interne/externe du tibia par rapport au fémur et sur l’avancée/recul du fémur par rapport au tibia pendant le mouvement de flexion du genou. / Knee kinematic is complex. It depends of geometric parameters and mechanical parameters. Geometric parameters are mainly defined by bone geometry, articular surfaces and by several soft tissues insertions. Mechanical parameters are defined by soft tissues characteristics designed by laws which link distances between their insertions and generated forces. Muscles, tendons, and ligaments are characterized by linear stiffness and pre-load at one specific position of knee joint: full extension. This work analyzes with rigid-body simulation tool, the knee joint comportment. First part of this work describes model construction. Second part places model inside external loads and constrains. Third part shows model results and compares them to several bibliographies. Last and forth part tests several values of each mechanical parameter. This part evaluates influence of parameter to knee kinematic. Synthesis of results helps to show most influent parameters on internal/external rotation of tibia relative to femur and on femur anterior/posterior displacement during knee flexion movement.
