Rethinking authenticity in digital art preservation

In this paper I am discussing the repositioning of traditional conservation concepts of historicity, authenticity and versioning in relation to born digital artworks, upon findings from my research on preservation of computer-based artifacts. Challenges for digital art preservation and previous work in this area are described, followed by an analysis of digital art as a process of components interaction, as performance and in terms of instantiations. The concept of dynamic authenticity is proposed, and it is argued that our approach to digital artworks preservation should be variable and digital object responsive, with a level of variability tolerance to match digital art intrinsic variability and dynamic authenticity

D+s production at central rapidity in Pb Pb collisions at sqrt{s_NN} = 2.76 TeV with the ALICE detector

We present the measurement of the D+s production in pp collisions at sqrt{s} = 7 TeV and in Pb Pb collisions at sqrt{s_NN} =2.76 TeV performed with the ALICE detector at central rapidity through the reconstruction of the hadronic decay channel D+s-> K+K-pi+. The preliminary results of the D+s nuclear modification factor will be presented

D+s production at central rapidity in pp collisions at 7 TeV with the ALICE experiment

We present the preliminary pt differential cross section in pp collisions of the D+s meson measured in the mid-rapidity region of ALICE with an integrated luminosity of 4.8 nb^-1. The ratios between all the D meson preliminary pt differential cross sections measured in the ALICE experiment (D+s,D0,D+,D*+) are also presented and compared with the results of other experiments.Comment: Presented at the 2011 Hadron Collider Physics symposium (HCP-2011), Paris, France, November 14-18 2011, 3 pages, 5 figur

Paradoxes versus formalism in economics. Evidence from the early years of game theory and experimental economics

This paper argues that the acceptance of two recent methodological advances in economics, namely game theory and laboratory experimentation, was affected by the history dependence constraining the formalization of economics. After an early period in which the two methods were coolly received by economists because their applications challenged some basic hypotheses of mainstream economics, their subsequent acceptance was the result of the corroboration of those same hypotheses. However, the recent emergence of some paradoxes has finally revealed that the effectiveness of game theory and experimental techniques in economics is improved when descriptively implausible and normatively unsatisfactory assumptions such as the centrality of individual maximization in decision theory and the definition of rationality as consistency in preferences are revised.paradoxes, game theory, experiments, individual maximization, economic rationality

Linking Strategic Interaction and Bargaining Theory. The Harsanyi - Schelling Debate on the Axiom of Symmetry

This paper analyses the early contributions of John Harsanyi and Thomas C. Schelling to bargaining theory. In his work, Harsanyi (1956) draws Nash’s solution to two-person cooperative games from the bargaining model proposed by Zeuthen (1930). Whereas Schelling (1960) proposes a multi-faceted theory of conflict that, without dismissing the assumption of rational behaviour, points out some of its paradoxical consequences. Harsanyi and Schelling’s contrasting views on the axiom of symmetry, as postulated by Nash (1950), are then presented. The analysis of this debate illustrates that, although in the early 1960s two different approaches to link strategic interaction and bargaining theory were proposed, only Harsanyi’s insights were fully developed later. Lastly, the causes of this evolution are assessed.bargaining, game theory, symmetry
