Die Erfindung des Paratextes : Überlegungen zur frühneuzeitlichen Textualität

Ausgehend von einem 2008 erschienenen Sammelband zur "Pluralisierung des Paratextes" setzt sich der Aufsatz mit der Anwendung des Paratextbegriffs bei Texten der Frühen Neuzeit auseinander. Es wird gezeigt, dass gerade vom Gegenteil von Pluralisierung gesprochen werden müsste und dass der Begriff Genettes erst ab der Neuzeit Gültigkeit besitzt, so dass nach Wegen zu suchen ist, wie mit Texten der Frühen Neuzeit adäquat umgegangen werden kann. Mit Blick auf verschiedene Ansätze der Forschung wird dargestellt, welche Bedeutung der Typographie zukommt und auf welche Weise Texte durch die je spezifische Gestaltung und Materialität an sozialen Netzwerken teilhaben. Vorgestellt wird der Begriff der "Soziotextualität", der den Begriff des Paratextes als eine spezifische Form von Soziotextualität umfasst

Thermodynamics of Strongly Correlated One-Dimensional Bose Gases

We investigate the thermodynamics of one-dimensional Bose gases in the strongly correlated regime. To this end, we prepare ensembles of independent 1D Bose gases in a two-dimensional optical lattice and perform high-resolution in situ imaging of the column-integrated density distribution. Using an inverse Abel transformation we derive effective one-dimensional line-density profiles and compare them to exact theoretical models. The high resolution allows for a direct thermometry of the trapped ensembles. The knowledge about the temperature enables us to extract thermodynamic equations of state such as the phase-space density, the entropy per particle and the local pair correlation function.Comment: 4 pages, 5 figure

Millimeter-long Fiber Fabry-Perot cavities

We demonstrate fiber Fabry-Perot (FFP) cavities with concave mirrors that can be operated at cavity lengths as large as 1.5mm without significant deterioration of the finesse. This is achieved by using a laser dot machining technique to shape spherical mirrors with ultralow roughness and employing single-mode fibers with large mode area for good mode matching to the cavity. Additionally, in contrast to previous FFPs, these cavities can be used over an octave-spanning frequency range with adequate coatings. We also show directly that shape deviations caused by the fiber's index profile lead to a finesse decrease as observed in earlier attempts to build long FFP cavities, and show a way to overcome this problem

Impact of chronic somatoform and osteoarthritis pain on conscious and preconscious cognitive processing

The study investigates the impact of chronic pain (CP) on conscious and preconscious cognitive processes and on guessing behavior, and examines the mediating effect of a depressive state. Twenty-eight patients with CP due to hip osteoarthritis, 32 patients with a somatoform disorder including pain symptoms, and 31 participants who did not have CP were examined within the framework of a modified Process-Dissociation-Procedure. Neutral, health threatening and general threatening stimuli were presented acoustically in a lexical decision task. Parameters of conscious processing, preconscious processing, and of chance were estimated by a multinomial modelling procedure. CP-patients with osteoarthritis showed the lowest level of conscious processing and the highest level of guessing behavior. Patients with somatoform pain tended to react preconsciously to health threatening stimuli but overall showed a profile similar to that of controls who did not have CP. The impact of the threatening quality of stimuli on different levels of cognitive processing was weak. Depression did not mediate between the experience of pain and estimates of conscious and preconscious processing. Perspective: The impact of CP on preconscious and conscious cognitive processing depends on types and causes of pain. The experience of CP caused by inflammation or physical damage tends to reduce the probability of conscious processing and to provoke memory biases. CP in the context of a somatoform disorder seems to have less impact on cognitive functions
