No full textWas ist ein Held, eine Heldin? Eine Figur, die bestimmte menschliche Eigenschaften, verkörpert, die wir für exemplarisch halten und Dinge tut, die vorbildlich sind? Ein normatives Beispiel also, das an unser Handeln appelliert und zur Identifikation, Nachahmung und Wertschätzung einlädt und vielen ein Vorbild ist. In der westlichen Kultur des späten 20. Jahrhundert ist diese Figur etwas aus der Mode gekommen. Das hängt wohl damit zusammen, dass im Zuge der Pluralisierung und Individualisierung der Lebensformen ein Konsens über verbindliche gemeinsame Normen im Schwinden begriffen ist. Das hat Folgen für die Art von Vorbild, die der Held oder die Heldin heute noch sein kann. Die ordnungsstiftende und handlungsorientierende Wirkungsmacht von Held*innen setzt in ihrer klassischen Form ein intaktes normatives Bezugssystem voraus. Doch was, wenn eine solche allgemeine Norm fehlt? Wenn mit der exponierten Stellung eines singulären Menschen keine Garantie auf einen starken Sinn verbunden wäre? Wäre dann das post-exemplarische Zeitalter zugleich ein post-heroisches? Ungeachtet dieser Entwicklung hat sich in der Populärkultur des 20. Jahrhunderts ein neues Genre, das Genre der Superhelden, etabliert, welches sich zur Zeit einer großen Beliebtheit erfreut. Am Beispiel des kinematographischen Bildungsromans Iron Man, wird Cremonini der Frage nachgehen, ob und wann der Superheld auch unter postmodernen Bedingungen als beispielhaft verstanden werden kann. Andreas Cremonini ist Philosoph und freier Wissenschaftler; er publiziert in den Bereichen Psychoanalyse, Phänomenologie und Theorien der Alterität.

No full textBecause of its non invasive nature, NMR is a unique tool for studying the
microstrusture of biological and material samples. This is usually done by monitoring
the diffusion coefficients and relaxation times, whose behavior is related to the
translational and rotational random molecular motion of the system components. These
parameters report on motion on very different time scales, thus providing structural
information at a microscopic scale well beyond the usual image resolution. However,
while relaxation-weighted images are relatively straightforward to record and analyze,
the study of diffusion through MRI calls for an higher level of complexity from both a
theoretical and instrumental point of view and it is nowadays well established in the
form of diffusion tensor imaging (DTI), a technique introduced by Basser et al. in 1994
[1]. Although software modules exist that alleviate the tedious task of setting all the
parameters for the DTI sequence in newer instruments or medical scanners, our old
spectrometer - a 4.7 Tesla Bruker AM WB equipped with a PFG drive unit for
microimaging - did not offer the "turnkey” DT-MRI Bruker acquisition interface. We
got round this by implementing a DTI acquisition module and analyzing the raw data
with an open source DTI reconstruction software [2]. Our experience led us to elaborate
some of the theoretical and methodological basic concepts of DTI, summarized in the
following steps: i) Theoretical basis and assumptions of the equations that lead to the
true and apparent calculation of the diffusion coefficient(s) [3]; ii) Acquisition scheme:
a diffusion-weighted preparation module based on stimulated echo (STEAM) to provide
long diffusion times with minimal T2 relaxation [4] prior to and independent of the
imaging scheme; iii) DTI scheme: the amount of diffusion weighting and at least six not
collinear PFG orientations (icosahedral geometry) to estimate the six independent
elements of the symmetric diffusion tensor; iv) the corrections for cross-terms
interactions [5]; v) reduction of eddy currents that generate image artifacts; vi) diffusion
tensor reconstruction from DTI raw data, providing information on sample
microstructure and architecture for each voxel: mean diffusivity; anisotropy indices and
fiber orientation mapping; vii) Phantoms to test and validate the whole procedure:
isotropic (water, BSA) and anisotropic (fibers and celery) at different anisotropy degre
I Think I Am Philip K. Dick
No full textFor years, noted writer Laurence A. Rickels often found himself compared to novelist Philip K. Dickthough in fact Rickels had never read any of the science fiction writers work. When he finally read his first Philip K. Dick novel, while researching for his recent book The Devil Notebooks , it prompted a prolonged immersion in Dicks writing as well as a recognition of Rickelss own long-documented intellectual pursuits. The result of this engagement is I Think I Am: Philip K. Dick , a profound thought experiment that charts the wide relevance of the pulp sci-fi author and paranoid visionary. I Think I Am: Philip K. Dick explores the science fiction authors meditations on psychic reality and psychosis, Christian mysticism, Eastern religion, and modern spiritualism. Covering all of Dicks science fiction, Rickels corrects the lack of scholarly interest in the legendary Californian author and, ultimately, makes a compelling case for the philosophical and psychoanalytic significance of Philip K. Dicks popular and influential science fiction.Intro -- Contents -- Introjection -- Part I -- Endopsychic Allegories -- Schreber Guardian -- Belief System Surveillance -- Part II -- Deeper Problems -- Veil of Tears -- Go West -- Dick Manfred -- Timing -- Glimmung -- Part III -- Spiritualism Analogy -- Imitating the Dead -- Indexical Layer -- Ilse -- Hammers and Things -- Crucifictions -- Over There -- Martyrology -- Can't Live, Can't Live -- Lola -- Umwelt, Mitwelt, and Eigenwelt -- Outer Race -- The German Introject -- Part IV -- Materialism, Idealism, and Cybernetics -- Startling Stories -- A Couple of Years -- Android Empathy -- Homunculus and Robot -- ALL OF YOU ARE DEAD.

The AM Canum Venaticorum binary SDSS J173047.59+554518.5
No full textThe AM Canum Venaticorum (AM CVn) binaries are a rare group of hydrogen-deficient, ultrashort period, mass-transferring white dwarf binaries and are possible progenitors of Type Ia supernovae. We present time-resolved spectroscopy of the recently discovered AM CVn binary SDSS J173047.59+554518.5. The average spectrum shows strong double-peaked helium emission lines, as well as a variety of metal lines, including neon; this is the second detection of neon in an AM CVn binary, after the much brighter system GP Com. We detect no calcium in the accretion disc, a puzzling feature that has been noted in many of the longer period AM CVn binaries. We measure an orbital period, from the radial velocities of the emission lines, of 35.2 ± 0.2 min, confirming the ultracompact binary nature of the system. The emission lines seen in SDSS J1730 are very narrow, although double-peaked, implying a low-inclination, face-on accretion disc; using the measured velocities of the line peaks, we estimate i ≤ 11°. This low inclination makes SDSS J1730 an excellent system for the identification of emission lines
Freedom of choice or force of circumstance? : Eastern European sex-workers in the Republic of Cyprus ; paper for the conference 'Alltag der Globalisierung. Perspektiven einer transnationalen Anthropologie', January 16-18, 2003, Institute of Cultural Anthropology and European Ethnology, Johann Wolfgang Goethe University, Frankfurt am Main
No full textThis paper focuses on Eastern European migrants who, since the beginning of the 1990s, are entering the Republic Cyprus as “artistes”. This is a visa permit status as well as an euphemism for short-term work permits in the local sex industry. In addition to exploring the migrational experiences of these women and their living and working conditions in the Republic of Cyprus, the paper reconstructs, empirically and analyt ically, the connection between immigration and the local sex industry. Here, several categories of social actors and institutions in Cyprus are actively involved. The rhetoric of government representatives, entrepreneurs and clients in the sex business on the one hand is contrasted with the discourse of local NGO representatives concerned with immigrants’ rights on the other hand. The paper comes to the conclusion that all of these discursive positions ultimately do not do justice to the complex process of decisionmaking that women undergo who migrate into the sex industry. Either, freedom of choice is emphasized – such as by entrepreneurs and the government – or the domination of women – as in the public statements of the NGO. In order to analyze the ambivalent tension between freedom of choice and submission to force by which the women’s decision is characterized, the author employs Michel Foucault’s concept of governmentality, which describes forms of political regulation that use the individual’s freedom of action as an instrument to exercise power
