Le Soulier de satin, tour à tour perçu comme oeuvre Dada, drame baroque ou pièce àclef, est une oeuvre dont l’étude de la création et la réception permet de mieuxappréhender les liens de Paul Claudel avec son temps. Dans cette pièce, Claudeleffectue la somme de l’héritage artistique de remise en cause de la société positiviste desa jeunesse et livre le récit de sa vocation poétique, enracinée dans la penséebaudelairienne et mallarméenne sur la modernité. La prégnance du paradigme picturalpour livrer son manifeste esthétique et l’utilisation de l’image sous toutes ses formespour entrer en dialogue avec le sens du texte vérifient la concordance d’intérêts entreClaudel et les artistes de sa génération. L’originalité du dramaturge réside dans sonrecours à l’image pour faire de son oeuvre un ex-voto qui retrace l’itinéraire de saconversion, l’inspiration thomiste le conduisant à privilégier l’image dans l’économiedu salut à l’oeuvre dans la pièce. L’oeuvre révèle enfin son affinité avec l’art modernepar son utilisation de procédés et de formes propres à l’art moderne, comme le collageet le montage, ou redécouverts par la modernité, comme l’empreinte ou la planéité,procédés et formes que Claudel emploie de manière polysémique et dialectique. Eninscrivant la question de sa vocation poétique, de sa conversion et de la réception de sonoeuvre par ses contemporains au coeur de la pièce, avec Le Soulier de satin, Claudeldonne une oeuvre qui s’inscrit pleinement dans le programme de la modernité tout enrévélant son originalité propre. / The Satin Slipper has been received alternately as a Dada work, a Baroque drama or a‘pièce à clé’, and studying both its first production and its reception allows one to graspbetter Claudel’s relationships with his days. In this work, Claudel adds up together theartistic legacy of his questioning the positivist society of his youth and gives thenarrative of his poetic vocation, which is rooted in the Baudelairean and Mallarméanthoughts on modernity. Claudel delivers his aesthetic manifesto through the primacy ofthe pictural paradigm and makes the reader establish a dialogue with the meaning of thetext, and all this makes him meet the concerns of the artists of his generation. Theplaywright’s originality lies in his resorting to the image to make his work into an exvoto that traces the itinerary of his conversion, as the Thomistic inspiration drives himto favour the image, in God’s plan at work in the play. Ultimately, the work discloses itscloseness to modern art through the use of devices and forms that are proper to modernart, such as collages and montages, or that were rediscovered by modernity, like theimprint or the planeness, that Claudel uses in a polysemous and dialectical way. As heincludes the questions of his poetic vocation, his conversion and the reception of hiswork by his contemporaries in the heart of the play, Claudel thrusts The Satin Slipperdeeply into the programme of modernity, original though it may be revealed.

Studies have shown elementary teachers may not be well prepared to use technology in their classrooms. This study examines one elementary teacher’s feelings of technology self-efficacy (TSE), needs and pedagogical strategies when using the interactive whiteboard (IWB) to teach elementary science. It employed a single case study design, where the researcher and participant worked together during supportive professional development (PD) sessions. Data sources are twelve PD sessions, the Computer Technology Integration Survey (adapted for IWB use in the classroom), and two interviews, three in-class observations of IWB science lessons, and three lesson debriefs. Descriptive and thematic analysis show the participant’s TSE was positively influenced by the PD. Five factors were determined to influence TSE: the participant’s level of interest, attitude, experience with technology, student assistance, and familiarity with the setting. Teacher, contextual and IWB- level needs were explained. Pedagogical strategies for technology use based on interactive IWB features are also discussed. Findings could contribute to current trends in teacher PD, continuing education, and preservice teaching programs related to science teaching. / Plusieurs enseignants ne sont pas bien préparés pour utiliser la technologie en classe. En particulier, le tableau blanc interactif (TBI) n’est pas utilisé de façon optimale par les enseignants lorsqu’ils enseignent les sciences et la technologie à l’élémentaire. Cette thèse présente l’étude de cas unique d’une enseignante de l’élémentaire ayant cheminé dans un processus de développement professionnel (DP) pour l’aider à intégrer le TBI en sciences et technologie. Douze sessions de DP, un questionnaire sur l’efficacité avec le TBI (CTIS adapté), deux entrevues, trois sessions d’observation en classe et trois discussions sur les leçons constituent les sources de données. La participante est devenue plus confiante pour utiliser le TBI suite au DP. Elle a rehaussé son sentiment d’autoefficacité et accru son intérêt et sa connaissance du TBI. Elle a acquis des compétences techniques et une connaissance des contenus d’enseignement adaptés au TBI, bien que plusieurs besoins perdurent. Certaines stratégies pédagogiques avec le TBI expérimentées en classe par l’enseignante sont discutées. Cette thèse peut contribuer à fournir des pistes pour aider les enseignants au primaire à mieux intégrer le TBI en sciences et technologie, que ce soit lors de leur formation initiale à l’enseignement ou en cours d’emploi.

Big amounts of data are produced every day in companies. By analyzing and visualizing the data a lot of insights can be gained. The company Solution Xperts wanted to create a system that could import and visualize Big Data. In this work a system was created and evaluated. The report shows that it can be difficult to visualize Big Data, but when a system is created it can easily be adapted to data coming from different companies and provide a lot of value to companies and organizations.

The main problem addressed by this dissertation is the accurate and automated determination of electron microscope imaging conditions. This enables the restoration of the object wave, which confers direct structural information about the specimen, from sets of differently aberrated images. An important member in the imaging chain is the image recording device, in many cases now a charge-coupled device (CCD) camera. Previous characterisations of these cameras often relied on the unjustified assumption that the Modulation Transfer Function (MTF) also correctly describes the spatial frequency dependent attenuation of the electron shot noise. A new theory is therefore presented that distinguishes between signal and noise transfer. This facilitates the evaluation of both properties using a detailed Monte-Carlo simulation model for the electron and photon scattering in the scintillator of the camera. Furthermore, methods for the accurate experimental determination of the signal and noise transfer functions are presented. In agreement with the Monte-Carlo simulations, experimental results for commercially available CCD cameras show that the signal transfer is significantly poorer than the noise transfer. The centrepiece of this dissertation is the development of new methods for determining the relative aberrations in a set of images and the absolute symmetric aberrations in the restored wave. Both are based on the analysis of the phase information in the Fourier domain and give each Fourier component a weight independent of its strength. This makes the method suitable even for largely crystalline samples with little amorphous contamination, where conventional methods, such as automated diffractogram fitting, usually fail. The method is then extended to also cover the antisymmetric aberrations, using combined beam tilt and focal series. The applicability of the new method is demonstrated with object wave restorations from tilt and focal series of complex inorganic block oxides and of carbon nanotubes filled with one-dimensional inorganic crystals. The latter specimens allowed for the first time a direct comparison between the phase shift in the restored object wave of a specimen with precisely known thickness and the value predicted by simulations.

After dedicating over two years to pursuing an MFA degree focused on ceramics and sculpture, I find myself transported back to a familiar setting from my past: a tableau reminiscent of what remained in the dining space after four young children finished a meal and exited the room. Revisiting the scene recalls happy times despite the disorder. What helped maintain my sanity during the relentless repetition of the every-day-long task was the realization that every day, innocents are learning to become aware of the world around them. For my thesis exhibition, I created a tableau as a loud reminder of those messier times in my home. My exhibition features an oversized wooden toddler's chair and table, surrounded by scattered meal-time remnants exaggerated in scale predominantly crafted from ceramic. The food items are strewn about in seemingly random arrangements, creating a chaotic still life. Perhaps the disproportionate size of the furniture and the disorderliness subconsciously acknowledge the monumental challenge of caring for children, a task that once felt never-ending but has since become a distant memory. Viewers may find solace in the mundane subject matter and in the ease of recognizing the familiar elements on display.

Wachsfigurenkabinette waren nicht immer die billigen Sensationsmaschinen, als die sie heute verstanden werden. Vor der Erfindung und Verbreitung von Photographie und illustrierten Zeitschriften waren sie Bildmedien, die der Vermittlung von visuellen Informationen dienten. Kein anderes Medium konnte die Protagonisten der Weltgeschichte so unmittelbar darstellen wie die Sammlungen lebensgroßer Wachsfiguren. Das Material Wachs trug wesentlich zu ihrem Erfolg bei, denn es ermöglichte die täuschend echten und bis dahin realistischsten Darstellungen von bekannten Persönlichkeiten. Die Operationsweise dieses Mediums wird am Beispiel von Madame Tussauds Wachsfigurenkabinett genauer untersucht. Dazu wurde, soweit möglich, die Reiseroute, der Aufbau und die “Besetzung” der Ausstellung rekonstruiert, sowie die soziale Herkunft der Besucher in der ersten Hälfte des 19. Jh.s ermittelt. Es wird deutlich, daß Marie Tussaud eine talentierte Portraitkünstlerin und ambitionierte Schaustellerin war, deren sorgfältig gestaltete Ausstellung vor allem Besucher der aufstrebenden Mittelschicht mit Interesse an Menschenkenntnis anzog. Das Wachsfigurenkabinett fiel damit in die Kategorie der “nützliche Unterhaltung”, die der Wissens- und Charakterbildung diente. Madame Tussaud ist vielleicht die bekannteste Betreiberin eines Wachsfigurenkabinetts – keinesfalls aber die erste. Die Geschichte der kommerziellen Ausstellung lebensgroßer Wachsfiguren reicht ins beginnende 17. Jh. zurück, wobei sich das Konzept der Kabinette im Laufe der Jahrhunderte stark gewandelt hat. In dieser Arbeit werden drei Ausstellungsformen unterschieden: a) das barocke Figurengruppen-Kabinett, das programmatische oder allegorische Geschichten erzählt, b) die aufklärerische Portraitgalerie (wie z.B. Madame Tussauds), in der Persönlichkeiten als charakteristische Individuen vorgestellt werden, c) das moderne Tableau-Kabinett, wo alltägliche oder außergewöhnliche Ereignisse auf bis dahin unübertroffen realistische Weise wiedergegeben werden. Als Nachrichtenkanal und als Medium für realistische Wirklichkeitswiedergabe sind Wachsfigurenkabinette seit den 1920er Jahren überholt. Als Spiel mit der menschlichen Sinneswahrnehmung bleiben sie jedoch vorerst aktuell. / Waxworks were not always the cheap sensation spinners as which we perceive them today. Before the invention and wide-spread use of photography and illustrated magazines they were an important medium for distributing visual information. No other form of communication could offer such immediate representations the protagonists of world history. Perhaps the greatest part in their success took the material wax which allowed the creation of deceptively lifelike and hitherto most realistic depictions of celebrated individuals. In this thesis, Madame Tussaud’s serves as a prime example for examining the mode of operation of a waxwork exhibition. As far as the sources allow, the itinerary, the ‘cast’ and display of the exhibition is reconstructed, as well as the number and the social background of its visitors during the first half of the 19th century. It emerges that Marie Tussaud was a talented portrait artist and a show woman of ambition whose carefully constructed exhibition attracted mainly middle-class visitors with an interest in human classification. Thus, the waxworks was a ‘rational entertainment’ that was thought to further the development of knowledge and character in its visitors. While Madame Tussaud’s was perhaps the most famous waxworks, it was not the first one. The history of commercial exhibition of life-sized wax figures goes back to the 17th century. Their concept, however, changed significantly over the centuries. Three forms of waxworks are differentiated here: a) the baroque waxworks of groups of figures narrating programmatic and allegorical stories, b) the enlightened portrait gallery – such as Madame Tussaud’s – where celebrities are presented as individual characters, c) the modern tableau waxworks, that represents extraordinary as well as everyday events in a realistic way that was hitherto unprecedented. As a channel for the distribution of news and as a medium for representing reality waxworks have become outdated. As a tickle for the senses, however, they will yet remain effective.

El propósito de nuestra investigación es analizar la imagen del París surrealista para luego ver su posterior recepción y variación por parte de Julio Cortázar en Rayuela. Los criterios analíticos de nuestra investigación constan en la importancia de la promenade y la visión en la construcción de la imagen de la ciudad a manera de espacio interior. Para comprender los orígenes e inserción en la tradición por parte de los surrealistas, fue necesario establecer los orígenes de las poéticas urbanas de la ciudad de París a finales del siglo XVIII, comprender el auge de París como tema literario a mediados del siglo XIX, analizar la importancia de la tradición noctámbula y la incidencia de Baudelaire en el París moderno para situar a los surrealistas en su manera de comprender la ciudad como un espacio psíquico e interior. Por último, comprenderemos los distintos elementos surrealistas de la construcción de París en Rayuela de Cortázar gracias a los textos escritos durante su período de interés surrealista (1947-1949) y su posterior variación en Rayuela. / The purpose of our investigation is to analyze the image of Paris forged in four Surrealist texts published between 1926-1928 in order to understand the Surrealist elements that allowed Julio Cortázar to forge his own image of the city in the novel Rayuela. Our analytical criteria are the importance of the regard and the promenade in the construction of the city as an interior and personal space. To understand the importance of the Surrealist production, it was necessary to visit the origins of Paris as a literary text in the late eitheenth century, the importance of the tradition noctámbule in the XIXth century, the incidences of Baudelaire's work regarding the modern Paris and the change of century that allowed the Surrealist movement to understand the city as an interior and psychic space. Through the establishment of certain criteria and images, we analyzed Paris in Cortázar's novel Rayuela as a Surrealist product, even if Cortázar himself never felt as as a Surrealist writer.

Le corpus d’œuvres et la synthèse des études menées sur les images de dévotion à l’époque médiévale n’ont jamais approfondi, dans le contexte européen, la question des peintures mariales ayant fonction de porte-reliques. Le modèle de tableau-reliquaire : panneau unique, diptyque et triptyque comprenant le portrait de la Vierge à l’Enfant peint sur bois (plus rarement sur verre églomisé) enchâssé dans un large cadre incrusté de reliques (parfois de pierres précieuses) se répandit particulièrement sur le territoire de la Petite-Pologne à partir des environs de 1420. Les reliquaires polonais, connus jusqu’au début du XVIe siècle, doivent sans doute être considérés comme une adaptation des types iconiques et formels de provenance byzantine, lesquels furent réinterprétés dans la peinture du Trecento italien. Il s’agit notamment du modèle siennois de retable portatif marial popularisé dès les années 1330-1340. D’après l’étude comparative des œuvres, relative à leurs caractéristiques similaires et leur ancienneté, on envisage l’arrivée d’un tel concept formel en Pologne soit directement de l’Italie, soit par l’intermédiaire de la Bohême.L’expansion des tableaux-reliquaires, typiques de l’art toscan, s’inscrivit au XVe siècle en Europe centrale dans le mouvement général du renouveau de piété, qu’était la devotio moderna. De sorte qu’à côté des représentations singulières, spécialement vénérées au cours des offices liturgiques et paraliturgiques, on voit se répandre des reliquaires moins coûteux dans l’espace privé. Appréciés dans l’intimité des couvents – franciscains et dominicains –, ainsi que dans celle du quotidien des laïcs, ils étaient utilisés comme des autels domestiques ou bien comme des autels pliables de voyage. Ces images d’affection religieuse constituent un phénomène artistique du bas Moyen Âge. Et, quelques-uns des reliquaires semblables connus postérieurement n’assurent pas une véritable continuité de l’ancien modèle à l’époque moderne. / Scholarly investigation of devotional images from the medieval period has never explored, in a European context, the question of Marian paintings functioning as portable relics. The model of the « picture-reliquary » : a single, diptych, or triptych panel comprsing the por-trait of the Virgin and Child painted on wood (or, more rarely, on gilded glass, verre églomisé) set in a large framework encrusted with relics (occasionally with precious stones) was particularly widespread in the territory of Little Poland from c. 1420. Polish reliquaries, known until the beginning of the 16th century, should be considered as an adaptation of iconic types and forms of Byzantine provenance, which were reinterpreted in the painting of the Italian Trecento. Of particular note is the Siennese model of the portable Marian altar piece made popular from the 1330s-40s. From the comparative study of the works, concerning their similarities and their antiquity, one envisages the advent of such a formal concept in Poland either directly from Italy, or by the intermediary of Bohemia.The diffusion of picture-reliquaries, typical of Tuscan art, forms part of the general movement toward a renewal of piety in central Europe in the 15th century, the devotio moderna. As a result, alongside singular representations, especially venerated in the course of liturgical or paraliturgical offices, one sees less costly reliquaries spread in private space. Appreciated in the intimate setting of convents – Franciscan and Dominican – as well as that of the daily life of the laity, these relics were used as domestic altars or as folding altars for travel. These images of religious affection constitute an artistic phenomenon of the late Middle Ages. And, several similar reliquaries known later do not guarantee a veritable continuity of the ancient model to the modern era. / Die erhaltenen Überblicksdarstellungen und Spezialuntersuchungen zu den Frömmigkeitsbildern des Mittelalters haben sich niemals – im europäischen Kontext – mit der Frage derjenigen Mariendarstellungen auseinandergesetzt, die die Funktion von Tragereliquien inne hatten. Das Modell des Reliquien-Bildes – einfaches Tafel-bild, Diptychon oder Triptychon mit einer Darstellung der Jungfrau mit dem Kind, gemalt auf Holz (seltener auf Glas), umschlossen von einem breiten Rahmen, in den Reliquien (mitunter auch Edelsteine) eingefügt sind – verbreitet sich ca. ab 1420 ins-besondere auf dem Gebiet Kleinpolens. Diese polnischen Reliquiare, bekannt bis zum Beginn des 16. Jahrhunderts, können ohne Zweifel als Adaptation ikonischer und formaler Typen byzantinischer Provenienz angesehen werden, die in der Malerei des italienischen Trecento wiederinterpretiert wurden. Dabei handelt es sich vor allem um das Sieneser Model des marianischen Tragaltars, verbreitet seit den Jahren 1330-1340. Folgt man den vergleichenden Untersuchungen der erhaltenen Stücke mit Blick auf ihre übereinstimmenden Charakteristika und ihr Alter, wird das Auf-greifen eines solchen formalen Konzepts in Polen entweder direkt aus Italien oder indirekt über Böhmen wahrscheinlich.Die Ausbreitung dieser Tafel-Reliquiare, typisch für die toskanische Kunst, verbindet sich im 15. Jahrhundert in Mitteleuropa mit der umfassenden Bewegung einer Er-neuerung der Frömmigkeit, bekannt auch unter dem Namen devotio moderna. Dies führt dazu, daß neben einzelnen, vor allem im Rahmen liturgischer oder paraliturgi-scher Veranstaltungen verehrten Darstellungen, zunehmend weniger kostspielige Reliquiare auch in den privaten Raum vordringen. Gehütet sowohl in der Intimität der Klöster – franziskanisch und dominikanisch – als auch im täglichen Lebensraum der Laien, wurden sie als Hausaltäre oder auch als zusammenklappbare Reisealtäre verwendet. Diese Darstellungen religiösen Affekts stellen ein künstlerisches Phäno-men des Spätmittelalters dar. Einige der ähnlichen, allerdings später entstandenen Reliquiare garantieren allerdings keine überzeugende Kontinuität vom alten Modell hin zur Neuzeit.

The present thesis investigates the music and career of Jeffrey Lewis (born 1942). The thesis is broadly divided into three sections. First is an account of the composer’s life, told mainly through an overview of his works, but also through a sketch of his early years in South Wales, his studies in Cardiff, Darmstadt, Kraków and Paris, his academic career in Leeds and Bangor, and his subsequent early retirement from academia. There follows a more detailed study of six works from the period 1978 – 1985, during which certain features of Lewis’s musical language came to the fore, perhaps most notably a very individual and instantly recognisable use of modal language. After an Epilogue, the thesis concludes with an Appendix in the form of a Catalogue in which all Lewis’s known compositions are listed, together with details of performances, broadcasts and recordings. Lewis’s music often plays with our temporal expectations; the close interrelationship between texture, structure, harmony and melody, and its effect upon our perception of the passage of time, are explored in the main analyses. These are conducted partly by means of comparison with other works by Lewis or his contemporaries. Memoria is examined in relation to a similarly tranquil score, Naaotwá Lalá, by Giles Swayne. The following chapter discusses the extra-musical inspiration for Epitaph for Abelard and Heloise, whose relationship to Tableau is then explored in the next. The difficulties of creating a large-scale structure that unifies the work’s various harmonic elements are also investigated. The analysis of Carmen Paschale considers it in relation to Lewis’s other choral music, whilst the final analytical chapter compares and contrasts two three-movement works, the Piano Trio and the Fantasy for solo piano. Lewis’s melodic writing in the Piano Trio is discussed in relation to that of James MacMillan, and the origins of the first movement of Fantasy in Oliver Knussen’s Sonya’s Lullaby are explored. In the Epilogue, the possible reasons for Lewis’s current neglect are explored, various influences on Lewis’s musical thinking are laid out, and his achievements are assessed.

Cette recherche aborde la problématique de la relation à la formation dans un processus d’autoformation en ligne. Elle pose la question du rapport au pouvoir dans ce type de situation d’apprentissage. La médiation pédagogique humaine et la médiatisation technologique y sont au centre des préoccupations. Il s’agit d’aborder, au travers de la conception même des instruments d’investigation, les concepts: de contrôle, d’autodirection, d’autonomie, d’efficacité, de compétence, d’autodétermination en relation avec la notion de motif d’engagement. Les dispositions et les prédispositions liées à l'autoformation sont également observées. On se propose de comprendre les orientations motivationnelles et les motifs qui éclairent l’engagement au regard de la perception de soi dans un contexte d’autoformation. Nos réflexions portent également sur le concept d'alterdidaxie par opposition aux démarches autodidactes dans un contexte d'autoformation./<p><p>This research approaches the problems in relation to training in the process of e-learning. It raises the question of the self-directed learning’s power in this type of training situation. The human teaching mediation and the technological mediatization are both in the center of the concerns. This research is an approach, through the design even of instruments of investigation, to the concepts :control, autodirection, autonomy, effectiveness, competence, self-determination in relation with the engagement. Competences and readiness scales related to the adults’ self-training are also observed. One proposes to observe motivational directions and the engagement’s reasons in relation with the perception of oneself as self-directed learners in a context of self-training. Our reflections also relate to the concept of Alterdidacticism in opposition to the self-educated steps, to the Autodidacticism in a context of adults’ self-training.<p><p> / Doctorat en Sciences Psychologiques et de l'éducation / info:eu-repo/semantics/nonPublished
