Una bella roba. ‘Novellare’ als Erzählkonzept in Boccaccios ›Decameron‹

Der narrative Entwurf von Boccaccios ›Decameron‹ und Boccaccios theoretische Reflexionen über das Erzählen stehen klar im Fluchtpunkt der horazischen Lehre des prodesse et delectare. Vor diesem Horizont entwickelt Boccaccio sein Konzept des novellare, das einerseits ein ‚Wiedererzählen’ (analog zu mhd. erniuwen) beinhaltet und andererseits zu einer neuen Autonomie des Erzählens vorstößt. Beobachten lässt sich dieser Vorgang des Erneuerns weniger in Boccaccios theoretischen Ausführungen (etwa im Schlusswort des ›Decameron‹ oder in den ›Genealogie deorum gentilium‹) als in seiner dichterischen Praxis. Als Schlüsseltext wird im Vortrag die Novelle von der duldsamen Griselda herangezogen, die das ›Decameron‹ beschließt und die mit den Worten una bella roba endet. Das ‚schöne Kleid’ ist einerseits traditionelle Dichtungsmetapher (im Horizont des investire bzw. integumentum), andererseits intradiegetischer Bestandteil des Erzähl-‚Stoffs’ der Novelle. Bei Boccaccio dürfte das Gewand der Griselda, zusammen mit deren wiederholt thematisierter Nacktheit, dazu dienen, eine in die Novelle verpackte stoische Lehre zu vergegenwärtigen, diese in eine Erzählung ‚einzukleiden’. Das Kleid der Griselda wird so zur ‚Pathosformel’ (in der Begrifflichkeit A. Warburgs) bzw. zum ‚Faltenwurf’ (in der Begrifflichkeit G. Didi-Hubermans), mithin zur Verkörperung eines ‚neuen Erzählens’, das sich (im Gegensatz etwa zu Dante) von metaphysischen Entwürfen emanzipiert und in der Autonomie sprachlicher Kunstfertigkeit, bis an die Grenzen des Erzählbaren gehend und didaktische Ansprüche überwindend, die Möglichkeiten literarischer Darstellung ausreizt. Von den Zeitgenossen wurde dieses Experiment zwar wahrgenommen, in seinen Dimensionen aber nur ansatzweise erkannt. Symptomatisch für diese Form der Rezeption ist Petrarcas lateinische Übersetzung der ›Griselda‹-Novelle (›Seniles‹, XVII,3), wobei der Verfasser – seinerseits die Kleidermetaphorik bemühend – das Übersetzen als ein stilo alio retexere auffasst und seine Version den (wohl vorwiegend männlich intendierten Lesern) als auf Gott hin orientierte Lehre anempfiehlt: ut legentes ad imitandam saltem femine constantiam excitarem, ut [...] hoc prestare Deo nostro audeant. Diese Rückführung von Boccaccios erzählerischem Wagnis ins Didaktische zeigt sich auch in der Rezeption von Petrarcas Übersetzung, durch welche die Novelle im Europa des 14. und 15. Jahrhunderts weite Verbreitung fand: In einer der Haupthandschriften von Chaucers ›Canterbury Tales‹, dem Hengwrt Manuscript (Aberystwyth, National Library of Wales), wird die auf der ›Griselda‹-Novelle aufbauende Erzählung des Scholaren (›The Clerk’s Tale‹) mit Bestandteilen aus Petrarcas Übersetzung glossiert; in einer Handschrift aus dem Besitz des Nürnberger Humanisten Hartmann Schedel (München, Bayerische Staatsbibliothek, Clm 504) wird Petrarcas Konzept des stilo alio retexere erläutert als: claram facere, nudare [...], aperire, wobei hier die in Boccaccios Novelle intradiegetisch enthaltene Spannung von ‚Einkleidung’ und ‚Nacktheit’ auf einer lehrhaften Ebene fortwirkt.

Measurement of the W+ W- cross section in sqrt(s) = 7 TeV pp collisions with ATLAS

This Letter presents a measurement of the W+ W- production cross section in sqrt(s) = 7  TeV pp collisions by the ATLAS experiment, using 34  pb(-1) of integrated luminosity produced by the Large Hadron Collider at CERN. Selecting events with two isolated leptons, each either an electron or a muon, 8 candidate events are observed with an expected background of 1.7 ± 0.6 events. The measured cross section is 41(-16)(+20)(stat) ± 5(syst)±1(lumi)  pb, which is consistent with the standard model prediction of 44 ± 3  pb calculated at next-to-leading order in QCD.

Search for a heavy particle decaying into an electron and a muon with the ATLAS detector in sqrt[s] = 7 TeV pp collisions at the LHC

This Letter presents the first search for a heavy particle decaying into an e ± μ(-/+) final state in sqrt[s] = 7 TeV pp collisions at the LHC. The data were recorded by the ATLAS detector during 2010 and correspond to a total integrated luminosity of 35 pb(-1). No excess above the standard model background expectation is observed. Exclusions at 95% confidence level are placed on two representative models. In an R-parity violating supersymmetric model, tau sneutrinos with a mass below 0.75 TeV are excluded, assuming all R-parity violating couplings are zero except λ(311)' = 0.11 and λ312 = 0.07. In a lepton flavor violating model, a Z'-like vector boson with masses of 0.70-1.00 TeV and corresponding cross sections times branching ratios of 0.175-0.183 pb is excluded. These results extend to higher mass R-parity violating sneutrinos and lepton flavor violating Z's than previous constraints from the Tevatron.

Measurement of dijet azimuthal decorrelations in pp collisions at sqrt(s)=7 TeV

Azimuthal decorrelations between the two central jets with the largest transverse momenta are sensitive to the dynamics of events with multiple jets. We present a measurement of the normalized differential cross section based on the full data set (∫Ldt=36  pb(-1)) acquired by the ATLAS detector during the 2010 sqrt(s)=7  TeV proton-proton run of the LHC. The measured distributions include jets with transverse momenta up to 1.3 TeV, probing perturbative QCD in a high-energy regime.

Search for supersymmetry using final states with one lepton, jets, and missing transverse momentum with the ATLAS detector in √s=7 TeV pp collisions

This Letter presents the first search for supersymmetry in final states containing one isolated electron or muon, jets, and missing transverse momentum from √s=7  TeV proton-proton collisions at the LHC. The data were recorded by the ATLAS experiment during 2010 and correspond to a total integrated luminosity of 35  pb(-1). No excess above the standard model background expectation is observed. Limits are set on the parameters of the minimal supergravity framework, extending previous limits. Within this framework, for A(0)=0 GeV, tanβ=3, and μ>0 and for equal squark and gluino masses, gluino masses below 700 GeV are excluded at 95% confidence level.

Search for diphoton events with large missing transverse energy in 7 TeV proton-proton collisions with the ATLAS detector

A search for diphoton events with large missing transverse energy is presented. The data were collected with the ATLAS detector in proton-proton collisions at √s=7 TeV at the CERN Large Hadron Collider and correspond to an integrated luminosity of 3.1 pb⁻¹. No excess of such events is observed above the standard model background prediction. In the context of a specific model with one universal extra dimension with compactification radius R and gravity-induced decays, values of 1/R<729 GeV are excluded at 95% C. L., providing the most sensitive limit on this model to date.

Search for a standard model Higgs boson in the H→ZZ→ℓ(+)ℓ(-)νν decay channel with the ATLAS detector

A search for a heavy standard model Higgs boson decaying via H→ZZ→→ℓ(+)ℓ(-)νν, where ℓ=e, μ, is presented. It is based on proton-proton collision data at √s=7 TeV, collected by the ATLAS experiment at the LHC in the first half of 2011 and corresponding to an integrated luminosity of 1.04 fb(-1). The data are compared to the expected standard model backgrounds. The data and the background expectations are found to be in agreement and upper limits are placed on the Higgs boson production cross section over the entire mass window considered; in particular, the production of a standard model Higgs boson is excluded in the region 340

Effects of Gender on the Incidence of Cardiac Tamponade Following Catheter Ablation of Atrial Fibrillation: Results from a Worldwide Survey in 34,943 AF Ablation Procedures.

BACKGROUND -Cardiac tamponade is the most dramatic complication observed during atrial fibrillation (AF) ablation and the leading cause of procedure-related mortality. Female gender is a known risk factor for complications during AF ablation; however, it is unknown whether women have a higher risk of tamponade. METHODS AND RESULTS -A systematic Medline search was used to locate academic electrophysiologic (EP) centers that reported cases of tamponade occurring during AF ablation. Centers were asked to provide information on cases of acute tamponade according to gender and their mode of management including any case of related mortality. Nineteen EP centers provided information on 34,943 ablation procedures involving 25,261 (72%) males. Overall 289 (0.9%) cases of tamponade were reported: 120 (1.24%) in females and 169 (0.67%) in males (odds ratio 1.83, P<0.001). There was a reciprocal association between center volume and the occurrence of tamponade with substantial lower risk in high volume centers. Most cases of tamponade occurred during catheter manipulation or ablation; females tended to develop more tamponades during transseptal catheterization. No gender difference in the mode of management was observed. However, 16% cases of tamponade required surgery with lower rates in high volume centers. Three cases of tamponade (1%) culminated in death. CONCLUSIONS -Tamponade during AF ablation procedures is relatively rare. Women have an almost twofold higher risk for developing this complication. The risk of tamponade among women decreases substantially in high volume centers. Surgical back-up and acute management skills for treating tamponade are important in centers performing AF ablation.
