Critical Performances

Philosophers of music commonly distinguish performative from critical interpretations. I would like to suggest that the distinction between critical and performative interpretations is well captured by an analogy to legal critics and judges. This parallel draws attention to several features of performative interpretation that are typically overlooked, and deemphasizes epistemic problems with performative interpretations that I believe are typically blown out of proportion and ultimately fail to capture interesting features of performative interpretation. There is an important distinction to be made between critical and performative interpretation, but its source lies in a difference between the authority of critical and performative interpretations

IBIS/PICsIT in-flight performances

PICsIT (Pixellated Imaging CaeSium Iodide Telescope) is the high energy detector of the IBIS telescope on-board the INTEGRAL satellite. PICsIT operates in the gamma-ray energy range between 175 keV and 10 MeV, with a typical energy resolution of 10% at 1 MeV, and an angular resolution of 12 arcmin within a \~100 square degree field of view, with the possibility to locate intense point sources in the MeV region at the few arcmin level. PICsIT is based upon a modular array of 4096 independent CsI(Tl) pixels, ~0.70 cm^2 in cross-section and 3 cm thick. In this work, the PICsIT on-board data handling and science operative modes are described. This work presents the in-flight performances in terms of background count spectra, sensitivity limit, and imaging capabilities.Comment: 8 pages, 4 figures.

Performances of peace: Utrecht 1713

The Peace of Utrecht (1713), which brought an end to the War of the Spanish Succession, was a milestone in global history. Performances of Peace aims to rethink the significance of the Peace of Utrecht by exploring the nexus between culture and politics. For too long, cultural and political historians have studied early modern international relations in isolation. By studying the political as well as the cultural aspects of this peace (and its concomitant paradoxes) from a broader perspective, this volume aims to shed new light on the relation between diplomacy and performative culture in the public spher

Actuation performances of anisotropic gels

We investigated the actuation performances of anisotropic gels driven by mechanical and chemical stimuli, in terms of both deformation processes and stroke--curves, and distinguished between the fast response of gels before diffusion starts and the asymptotic response attained at the steady state. We also showed as the range of forces that an anisotropic hydrogel can exert when constrained is especially wide;indeed, changing fiber orientation allows to induce shear as well as transversely isotropic extensions.Comment: 11 pages, 11 figure
