Proměny tendencí v sebereflexivním vyprávění: kontrastivní studie. / Changing Tendencies in Self-Conscious Narratives: A Contrastive Interpretation

Sedláček, Martin January 2017 (has links)
Thesis Abstract The present thesis investigates correlations between a selection of metafictional texts and narrative theory. The selection consists in two sets of self-reflexive texts. The first one explores metafictional tendencies in the 17th and 18th century novels. To achieve this, the selection largely ignores their provenience. In addition to Henry Fielding's Tom Jones and Laurence Sterne's Tristram Shandy, it also examines Cervantes's Don Quixote. The latter set of texts focuses on post-War American metafictions (John Barth's Lost in the Funhouse, Donald Barthelme's Snow White, Kurt Vonnegut's Slaughterhouse-Five). These represent a coherent body of works from a particular period. Metafiction is generally understood as fiction about fiction. The present thesis challenges those assumptions and suggests interpreting metafiction within the framework of Michel Foucault's epistemes. Metafiction is not conceived of as a separate genre of literature but in the context of broader cultural tendencies in the understanding of representation. Representation is a key concept in metafiction and the increasing degree of narrative self-awareness is viewed in this light. The thesis emphasizes this contrastive and interdisciplinary approach. The text is divided into five chapters. Chapter one is a theoretical...

EI Eridani and the art of doppler imaging : a long-term study / EI Eridani and the art of doppler imaging : a long-term study

Washüttl, Albert January 2004 (has links)
Das Verständnis magnetisch verursachter Aktivität auf Sternen sowie der zugrundeliegenden Dynamoprozesse ist von fundamentaler Bedeutung für das Verständnis von Entstehung und Entwicklung von Sternen sowie des Lebens im Universum. Sichtbare Erscheinungen dieser stellaren Aktivität sind u.a. Sternflecken, welche als Indikatoren des zugrundeliegenden Magnetfeldes dienen. Solche Flecken können auf anderen Sternen als der Sonne nicht direkt beobachtet werden, zumal mit den heutigen technischen Mitteln eine Auflösung der Oberfläche selbst der benachbarten Sterne unmöglich ist. Eine indirekte Rekonstruktionsmethode namens 'Doppler Imaging' erlaubt es jedoch, auf die Temperaturverteilung auf der Sternoberfläche zu schließen. Für diese Arbeit wurden elf Jahre kontinuierlicher spektroskopischer Beobachtungen des aktiven Doppelsterns EI Eridani herangezogen, um insgesamt 34 Dopplerkarten zu erstellen. In der Folge wird versucht, eine Grundlage zu schaffen für die Analyse des zweidimensionalen Informationsgehalts dieser Karten. Drei Oberflächenkartenparameter werden vorgeschlagen: gemittelte Temperatur, getrennt für verschiedenen stellare Breitenbänder; relative Fleckenhäufigkeit; und, zum Zwecke der Auswertung der strukturellen Temperaturverteilung, Längen- und Breiten-Ortsfunktion der Sternfleckenhäufung. Die resultierenden Werte zeigen deutlich, daß kein zeitlicher Zusammenhang mit dem photometrischen Aktivitätszyklus besteht. Die Morphologie der Fleckenverteilung bleibt während des kompletten Beobachtungszeitraums im wesentlichen konstant. Im Gegensatz zur Sonne gibt es also, im beobachteten Zeitraum und innerhalb der bestehenden Genauigkeit, keinen Fleckenzyklus auf dem aktiven Stern EI Eri. Darüberhinaus wurde eine ausführliche Studie der stellaren Parameter von EI Eri und eine vorläufige Abschätzung der differentiellen Rotation auf EI Eri durchgeführt, die eine anti-solare Ausrichtung aufzuweisen scheint, d.h. der Pol rotiert schneller als der Äquator. / Understanding stars, their magnetic activity phenomena and the underlying dynamo action is the foundation for understanding 'life, the universe and everything' - as stellar magnetic fields play a fundamental role for star and planet formation and for the terrestrial atmosphere and climate. Starspots are the fingerprints of magnetic field lines and thereby the most important sign of activity in a star's photosphere. However, they cannot be observed directly, as it is not (yet) possible to spacially resolve the surfaces of even the nearest neighbouring stars. Therefore, an indirect approach called 'Doppler imaging' is applied, which allows to reconstruct the surface spot distribution on rapidly rotating, active stars. In this work, data from 11 years of continuous spectroscopic observations of the active binary star EI Eridani are reduced and analysed. 34 Doppler maps are obtained and the problem of how to parameterise the information content of Doppler maps is discussed. Three approaches for parameter extraction are introduced and applied to all maps: average temperature, separated for several latitude bands; fractional spottedness; and, for the analysis of structural temperature distribution, longitudinal and latitudinal spot-occurrence functions. The resulting values do not show a distinct correlation with the proposed activity cycle as seen from photometric long-term observations, thereby suggesting that the photometric activity cycle is not accompanied by a spot cycle as seen on the Sun. The general morphology of the spot pattern on EI Eri remains persistent for the whole period of 11 years. In addition, a detailed parameter study is performed. Improved orbital parameters suggest that EI Eri might be complemented by a third star in a wide orbit of about 19 years. Preliminary differential rotation measurements are carried out, indicating an anti-solar orientation.

The relation between interstellar turbulence and star formation

Klessen, Ralf S. January 2004 (has links)
Eine der zentralen Fragestellungen der modernen Astrophysik ist es, unser Verständnis fuer die Bildung von Sternen und Sternhaufen in unserer Milchstrasse zu erweitern und zu vertiefen. Sterne entstehen in interstellaren Wolken aus molekularem Wasserstoffgas. In den vergangenen zwanzig bis dreißig Jahren ging man davon aus, dass der Prozess der Sternentstehung vor allem durch das Wechselspiel von gravitativer Anziehung und magnetischer Abstossung bestimmt ist. Neuere Erkenntnisse, sowohl von Seiten der Beobachtung als auch der Theorie, deuten darauf hin, dass nicht Magnetfelder, sondern Überschallturbulenz die Bildung von Sternen in galaktischen Molekülwolken bestimmt.<br /> <br /> Diese Arbeit fasst diese neuen Überlegungen zusammen, erweitert sie und formuliert eine neue Theorie der Sternentstehung die auf dem komplexen Wechselspiel von Eigengravitation des Wolkengases und der darin beobachteten Überschallturbulenz basiert. Die kinetische Energie des turbulenten Geschwindigkeitsfeldes ist typischerweise ausreichend, um interstellare Gaswolken auf großen Skalen gegen gravitative Kontraktion zu stabilisieren. Auf kleinen Skalen jedoch führt diese Turbulenz zu starken Dichtefluktuationen, wobei einige davon die lokale kritische Masse und Dichte für gravitativen Kollaps überschreiten koennen. Diese Regionen schockkomprimierten Gases sind es nun, aus denen sich die Sterne der Milchstrasse bilden. Die Effizienz und die Zeitskala der Sternentstehung hängt somit unmittelbar von den Eigenschaften der Turbulenz in interstellaren Gaswolken ab. Sterne bilden sich langsam und in Isolation, wenn der Widerstand des turbulenten Geschwindigkeitsfeldes gegen gravitativen Kollaps sehr stark ist. Überwiegt hingegen der Einfluss der Eigengravitation, dann bilden sich Sternen in dichten Gruppen oder Haufen sehr rasch und mit grosser Effizienz. <br /> <br /> Die Vorhersagungen dieser Theorie werden sowohl auf Skalen einzelner Sternentstehungsgebiete als auch auf Skalen der Scheibe unserer Milchstrasse als ganzes untersucht. Es zu erwarten, dass protostellare Kerne, d.h. die direkten Vorläufer von Sternen oder Doppelsternsystemen, eine hochgradig dynamische Zeitentwicklung aufweisen, und keineswegs quasi-statische Objekte sind, wie es in der Theorie der magnetisch moderierten Sternentstehung vorausgesetzt wird. So muss etwa die Massenanwachsrate junger Sterne starken zeitlichen Schwankungen unterworfen sein, was wiederum wichtige Konsequenzen für die statistische Verteilung der resultierenden Sternmassen hat. Auch auf galaktischen Skalen scheint die Wechselwirkung von Turbulenz und Gravitation maßgeblich. Der Prozess wird hier allerdings noch zusätzlich moduliert durch chemische Prozesse, die die Heizung und Kühlung des Gases bestimmen, und durch die differenzielle Rotation der galaktischen Scheibe. Als wichtigster Mechanismus zur Erzeugung der interstellaren Turbulenz lässt sich die Überlagerung vieler Supernova-Explosionen identifizieren, die das Sterben massiver Sterne begleiten und große Mengen an Energie und Impuls freisetzen. Insgesamt unterstützen die Beobachtungsbefunde auf allen Skalen das Bild der turbulenten, dynamischen Sternentstehung, so wie es in dieser Arbeit gezeichnet wird. / Understanding the formation of stars in galaxies is central to much of modern astrophysics. For several decades it has been thought that the star formation process is primarily controlled by the interplay between gravity and magnetostatic support, modulated by neutral-ion drift. Recently, however, both observational and numerical work has begun to suggest that supersonic interstellar turbulence rather than magnetic fields controls star formation. <br /> <br /> This review begins with a historical overview of the successes and problems of both the classical dynamical theory of star formation, and the standard theory of magnetostatic support from both observational and theoretical perspectives. We then present the outline of a new paradigm of star formation based on the interplay between supersonic turbulence and self-gravity. Supersonic turbulence can provide support against gravitational collapse on global scales, while at the same time it produces localized density enhancements that allow for collapse on small scales. The efficiency and timescale of stellar birth in Galactic gas clouds strongly depend on the properties of the interstellar turbulent velocity field, with slow, inefficient, isolated star formation being a hallmark of turbulent support, and fast, efficient, clustered star formation occurring in its absence. <br /> <br /> After discussing in detail various theoretical aspects of supersonic turbulence in compressible self-gravitating gaseous media relevant for star forming interstellar clouds, we explore the consequences of the new theory for both local star formation and galactic scale star formation. The theory predicts that individual star-forming cores are likely not quasi-static objects, but dynamically evolving. Accretion onto these objects will vary with time and depend on the properties of the surrounding turbulent flow. This has important consequences for the resulting stellar mass function. Star formation on scales of galaxies as a whole is expected to be controlled by the balance between gravity and turbulence, just like star formation on scales of individual interstellar gas clouds, but may be modulated by additional effects like cooling and differential rotation. The dominant mechanism for driving interstellar turbulence in star-forming regions of galactic disks appears to be supernovae explosions. In the outer disk of our Milky Way or in low-surface brightness galaxies the coupling of rotation to the gas through magnetic fields or gravity may become important.

The Divided Stage and Its Audience:The Representation of Subjectivity in Laurence Sterne¡¦s Tristram Shandy

F. Chiou, Theresa 19 July 2004 (has links)
Being classified in the ¡§anti-tradition of unclassifiable books,¡¨ Laurence Sterne¡¦s The Life and Opinions of Tristram Shandy, Gent. has fascinated generations of readers and critics with its seemingly chaotic richness. The narrator Tristram appears to hide his ultimate purpose and unity beneath a cloak of oddity and confusion, which defies any attempt on the reader¡¦s part to ever pinning it down, and thus opens ground for various debates and critiques. Taking Tristram¡¦s many futile efforts at tracing back the origin of his life as the starting point, this thesis attempts to explore the author-narrator¡¦s deliberate use of oddity and confusion. The impossibility of ever finding a coherent and definite beginning of one¡¦s life is read in my study as a metaphor of one¡¦s losing battle at pinning down the concept of self, the embodiment of the ungraspable subjectivity. Not even Locke¡¦s epistemology or the eighteenth-century knowledge of anthropology can serve as an adequate framework of reference for the account of one¡¦s life, if it is to be interpreted as subjectivity. The fact that men are different from one another arises from their individual hobbyhorse, the manifestation of subjectivity, which resists attempts to be defined exactly and thus makes itself unfathomable. This discovery is the very basis of my reading of Tristram Shandy. Since subjectivity refuses to be grasped, my thesis then proceeds to investigate the way in which Tristram represents this ungraspable subjectivity. The concept of staging is employed in this thesis to explore Sterne¡¦s deployment of subjectivity. On the stage where the many facets of each character¡¦s singular microcosm are presented, it is demonstrated that the reader is also drawn into Tristram¡¦s game play, only with the peculiar result that in discovering subjectivity (theirs and ours,) we trespass boundary and assume Tristram¡¦s subjectivity.

Mischievous partners and systemless systems : Laurence Sterne's Tristram Shandy and Friedrich Schlegel's concept of irony

Frock, Clare January 1992 (has links)
This thesis considers Laurence Sterne's Tristram Shandy in light of Friedrich Schlegel's concept of irony. Departing from previous criticism, which focuses on Sterne's playful narrative techniques, the discussion here elucidates other ways in which Tristram Shandy exemplifies the kind of irony Schlegel theorizes. These ways include: Sterne's "Mischgedicht" method, which amalgamates in a single work many types of style, or diverse permutations of form and content; the depiction of Parson Yorick, who epitomizes Socratic irony as Schlegel defines it in the 108th Lyceum fragment; Sterne's gentle satirizing of systematic thinkers, including his own narrator, Tristram; and Sterne's attitude toward words, knowledge, and reading. At the end of chapter 5, Sterne's irony is unraveled and reconstructed. This disentangling leads to a proposed refutation of recent interpretation of both Sterne and Schlegel. These studies see Sterne and Schlegel's irony as implying lack or flux of meaning. It is the strong contention of the following thesis that an essential aspect of Sterne and Schlegel's shared ironic world view is the continual, optimistic attempt to understand life, which necessarily presupposes a sincere and profound belief in both meaning and the reliable conveyance of it.
