Theatre constitutes a form of collective creativity. This idea is not as self-evident as one might expect. To some extent the collective Character of this art form had to be rediscovered over the course of the twentieth century, as theatre emancipated itself from the primacy of the literary text and thus from the primacy of the author. In fact, the collective character of this art form was fully brought into view again only with the debates about a post-dramatic theatre of the last few decades. In this essay I will tum back to the point in cultural history when literature started to dominate theatre and when the supremacy accorded the author began to annul theatre's collective character. This paradigmatic shift in the evolution of theatre occurred during the eighteenth century, and it is represented primarily by Johann Christoph Gottsched. In the following I will investigate Gottsched's efforts to reform the theatre of his age from a mediological point of view.
HDL, through sphingosine-1-phosphate (S1P), exerts direct cardioprotective effects on ischemic myocardium. It remains unclear whether other HDL-associated sphingophospholipids have similar effects. We therefore examined if HDL-associated sphingosylphosphorylcholine (SPC) reduces infarct size in a mouse model of transient myocardial ischemia/reperfusion. Intravenously administered SPC dose-dependently reduced infarct size after 30 minutes of myocardial ischemia and 24 hours reperfusion compared to controls. Infarct size was also reduced by postischemic, therapeutical administration of SPC. Immunohistochemistry revealed reduced polymorphonuclear neutrophil recruitment to the infarcted area after SPC treatment, and apoptosis was attenuated as measured by TUNEL. In vitro, SPC inhibited leukocyte adhesion to TNFα-activated endothelial cells and protected rat neonatal cardiomyocytes from apoptosis. S1P3 was identified as the lysophospholipid receptor mediating the cardioprotection by SPC, since its effect was completely absent in S1P3-deficient mice. We conclude that HDL-associated SPC directly protects against myocardial reperfusion injury in vivo via the S1P3 receptor.
Reforms or bankruptcy?

Almost 20 Greek academic economists from renowned universities in Europe and the US have prepared a one-page statement regarding the Greek crisis. In their statement the economic experts call upon the Greek public to accept the economic program of structural reforms, privatization, efficient tax collection, and shrinking of the public sector proposed and financed by the EU partners and the IMF. Among the signatories are this year's Nobel Prize winner Christopher Pissarides and Michalis Haliassos, Director of the Center for Financial Studies and Professor for Macroeconomics and Finance at the House of Finance.
This dissertation consists of three essays, which study the implication of financial frictions in business cycles and monetary policy making. The first essay develops a Dynamic Stochastic General Equilibrium (DSGE) model to study how the instability of the banking sector can amplify and propagate business cycles. Model simulations show that in an economic down turn, in addition to credit demand contraction induced by low firm net worth, low bank capital
position can create strong credit supply contraction, and have a quantitatively significant effect on business cycle dynamics. The second essay studies the optimal Taylor-type monetary policy rules based on the model developed in the first chapter and find that with interest rate smoothing, 'leaning against the wind' can significantly dampen the procyclicality of financial distortions, and increase the welfare of the economy. The third chapter examines the role of households frugality in a financial crisis and finds that higher savings by more frugal households provide an important cushion for the fall in private investment funding.

Contrary to widely held perceptions, workers in the southern European states that are most afflicted by the sovereign debt crisis work hard. However, labor productivity in these countries lags far behind the EU average. Structural reforms to boost productivity should be at the top of the reform agenda.
Neoma, a new genus of Cerambycidae (Coleoptera: Cerambycidae: Prioninae: Macrotomini) is described for Mallodonopsis corrosus Bates, 1879, compared to related genera (Aplagiognathus Thomson, 1861; Archodontes Lameere, 1903; and Mallodonopsis Thomson, 1861), and its tribal position discussed. A lectotype for Mallodonopsis corrosus is here designated with the species redescribed and figured.
The monotypic aesaline genus Lucanobium Howden and Lawrence (Coleoptera: Lucanidae) was previously known only from Venezuela. A second species is here described as new from French Guiana, extending the range of the genus approximately 1800 km to the southeast. The generic description of Lucanobium is updated with respect to the discovery of a second species.
