„In die Ferne sehe ich ausgezeichnet“ : Eine Motivstudie zu Augen in Marlen Haushofers Roman Die Wand.

Lundström, Petra January 2018 (has links)
In Haushofers Roman Die Wand werden die Augen auffällig betont und der Sehvorgang ausführlich geschildert. Diese Arbeit beschäftigt sich mit den Fragen: Wie und wo wird das Augenmotiv im Roman betont? Welche Funktionen haben die vielen Schilderungen von Augen und Schauen? Und welche Themen können dadurch behandelt werden? Dies wird durch ausgewählte Szenen und Textabschnitte diskutiert. Meine kurze Präsentation von dem Motiv Augen und Schauen in der Literaturgeschichte dient in diesem Aufsatz als ein theoretischer Grund.

Alban Berg as Liedkomponist: An Analytical Study of his Two Settings of "Schliesse mir die Augen beide," 1907 and 1925

Ray, Karen, 1951- 05 1900 (has links)
Alan Berg's two musical settings of Theodor Storm's poem"Schliesse mir die Augen beide" have received little in the way of scholarly analytical attention. The three major chapters of this thesis deal with the two settings on three different levels. Chapter II surveys the political and cultural milieu in which Berg functioned as a young composer of Lieder in the years 1900-1910. Chapter III examines the special quality of lyricism which is often attributed to Berg and his works. Chapter IV provides more definitive and complete musical analyses of the two settings than have heretofore been available. The question of what role songwriting played in the development of Berg's compositional process is addressed in the conclusion.

Statistical Evaluation of Correlated Measurement Data in Longitudinal Setting Based on Bilateral Corneal Cross-Linking

Herber, Robert, Graehlert, Xina, Raiskup, Frederik, Veselá, Martina, Pillunat, Lutz E., Spoerl, Eberhard 13 April 2023 (has links)
Purpose In ophthalmology, data from both eyes of a person are frequently included in the statistical evaluation. This violates the requirement of data independence for classical statistical tests (e.g. t-Test or analysis of variance (ANOVA)) because it is correlated data. Linear mixed models (LMM) were used as a possibility to include the data of both eyes in the statistical evaluation. Methods The LMM is available for a variety of statistical software such as SPSS or R. The application was applied to a retrospective longitudinal analysis of an accelerated corneal cross-linking (ACXL (9*10)) treatment in progressive keratoconus (KC) with a follow-up period of 36 months. Forty eyes of 20 patients were included, whereas sequential bilateral CXL treatment was performed within 12 months. LMM and ANOVA for repeated measurements were used for statistical evaluation of topographical and tomographical data measured by Pentacam (Oculus, Wetzlar, Germany). Results Both eyes were classified into a worse and better eye concerning corneal topography. Visual acuity, keratometric values and minimal corneal thickness were statistically significant between them at baseline (p < 0.05). A significant correlation between worse and better eye was shown (p < 0.05). Therefore, analyzing the data at each follow-up visit using ANOVA partially led to an overestimation of the statistical effect that could be avoided by using LMM. After 36 months, ACXL has significantly improved BCVA and flattened the cornea. Conclusion The evaluation of data of both eyes without considering their correlation using classical statistical tests leads to an overestimation of the statistical effect, which can be avoided by using the LMM.

Trematodes modulate aquatic food webs by altering host feeding behaviour

Vivas Muñoz, Jenny Carolina 01 November 2019 (has links)
Parasiten können den Energietransfer in Lebensgemeinschaften über trophische Kaskaden beeinflussen, indem sie Änderungen in den Konsumenten-Ressourcen-Interaktionen induzieren. In der vorliegenden Arbeit wurde die Rolle von Trematoden auf das Freßverhalten ihrer Wirte auf zwei trophischen Ebenen untersucht. Vier verschiedene Süßwasserschnecken-Trematoden-Systeme wurden verwendet, um zu testen, ob ein allgemeines Muster für die Auswirkung von Infektionen auf die Grazingaktivität von Schnecken auf das Periphyton nachgewiesen werden kann. Die Grazingraten auf Periphyton bei infizierten Schnecken entweder höher, niedriger oder ähnlich denen derjenigen von nicht infizierten Artgenossen. Augenparasiten können die Leistungsfähigkeit ihres Wirtes beeinträchtigen, was die Auswirkungen auf das Erkennen von Beutetieren, Raubtieren und Artgenossen hat. Mit Tylodelphys clavata experimentell infizierte Flussbarsche wurden mit zwei verschiedenen Beutetierarten eingesetzt, um das Fraßverhalten in Konkurrenz mit nicht infizierten Artgenossen zu untersuchen. Die Entfernung, aus der infizierte Fische die beiden Beutetierarten attackierten, war im Vergleich zu nicht infizierten Artgenossen signifikant kürzer. Die Tendenz war, dass nicht infizierte Fische mehr von den verfügbaren Beutetieren verzehrten. Um zu prüfen, ob der Fisch als Kompensation seine Beutepräferenz verändert, wurde die Beutezusammensetzung von Flussbarschen aus dem Müggelsees mittels Mageninhalts- und Stabilisotopenanalysen untersucht. Beide Methoden ergaben, dass sich die Fische mit zunehmender Intensität der Infektion selektiver ernährten, während sich geringer infizierte Fische Generalisten herausstellten. Die Ergebnisse dieser Studie bestätigen, dass Trematoden eine wichtige Rolle in Nahrungsnetzen spielen können, indem sie das Freßverhalten ihres Wirtes verändern. Darüber hinaus können Trematoden so die Stärke der Interaktion ihrer Wirte mit anderen Arten auf verschiedenen trophischen Ebenen beeinflussen. / Parasites can influence energy transfer through communities via trophic cascades by inducing alterations on consumer-resource interactions. This study evaluated the role of trematodes on their host’s feeding behaviour at two trophic levels. Four different freshwater snail–trematode systems were used to test whether a general pattern can be detected for the impact of infections on snail periphyton grazing activity. Mass-specific periphyton grazing rates of infected snails were higher, lower, or similar to rates of non-infected conspecifics. The variation across systems may result from differences on how the parasites use the resources of the snail and thus affect its energy budget. Eye parasites can impair their host’s sensory performance with important consequences for the detection of prey, predators and conspecifics. European perch experimentally infected with Tylodelphys clavata were used to evaluate their feeding behaviour under competition with non-infected conspecifics, for two different prey species (Asellus aquaticus and Daphnia magna). The distance at which infected fish attacked both prey species was significantly shorter in comparison to non-infected conspecifics. Additionally, infected fish had more unsuccessful attacks and there was a general tendency that non-infected fish consumed more of the available prey. To evaluate whether fish alter their prey preference as a compensatory mechanism, perch from Lake Müggelsee were sampled and their diet was evaluated using both stomach content and stable isotope analyses. Both methods indicated that with increasing infection intensity fish had a more selective diet, while less intensively infected fish appeared to be generalist feeders. The results from this study confirm that trematodes can play a relevant role within food webs by altering their hosts’ feeding behaviour. Furthermore, in this way trematodes can affect the interaction strengths of their hosts with other species at various trophic levels.
