This paper presents the results of a within-subject experiment testing whether an increase in the monetary stakes by a factor of 50 – which had never been done before – influences individual behavior in a simple ultimatum bargaining game. Contrary to current wisdom, we found that lowest acceptable offers stated by the responder are proportionally lower in the high-stake condition than in the low-stake condition. This result may be interpreted in terms of the type of utility functions which characterize the (...) subjects. However, in line with prior results, we find that an important increase of the monetary stakes in the ultimatum game has no effect on the offers made by the proposer. Yet, the present research suggests that the reasons underlying these offers are quite different when the stakes are high. (shrink)

It is shown that the uncertainty connected with a `random in a broad sense' (not necessarily stochastic) event always has some `statistical regularity' (SR) in the form of a family of finite-additive probability distributions. The specific principle of guaranteed result in decision making is introduced. It is shown that observing this principle of guaranteed result leads to determine the one optimality criterion corresponding to a decision system with a given `statistical regularity'.

Rapprocher Facebook du Kula mélanésien, un système archaïque d’échanges intertribaux décrit par Marcel Mauss, permet de souligner la capacité de la plateforme phare du Web 2.0 à répondre à des besoins socioculturels anthropologiquement attestés. Tous deux obéissent à une contrainte implicite de réciprocité qui, au-delà du contenu matériel des échanges, possède une fonction symbolique : les interactions mises en œuvre et la recherche de partenaires traduisent une quête de prestige, de mana selon le fameux terme chinook. Le Kula et les (...) murs de Facebook offrent une immense vitrine où chacun valorise son mana et scrute celui d’autrui tout en cherchant de nouveaux partenaires. Mobiliser le Kula tel un modèle de Simmel – un schème d’intelligibilité – indique l’ancienneté de ces traits culturels : la combinaison des dimensions matérielle et symbolique dans les échanges entre pairs et, en l’absence d’instance régulatrice, le risque lié à l’emballement de ce processus inévitablement concurrentiel.Our comparison between Facebook and Melanesia’s Kula, an archaic system of inter-tribal exchanges described by Marcel Mauss, has highlighted the ability of the flagship Web 2.0 platform to respond to anthropologically verified socio-cultural needs. Both systems obey an implicit demand for reciprocity, which, over and above the actual content of exchanges, has a symbolic function: the interactions at play and the search for partners reflect a quest for prestige, or mana as it is famously known in Chinook. Kula and Facebook’s walls are a gigantic shop window where anyone can show off their mana and look at other people’s, while also seeking out other partners. The use of the Kula as described by Simmel – as a model of intelligibility – suggests the ancient roots of these cultural traits: the combination of material and symbolic dimensions in exchanges between peers and, if there is no regulating authority, the risk that this inevitably competitive process may run out of control.

Paris a connu au xixe siècle une héroïsation la haussant au rang d’une Babylone ou Babel moderne. Le mur des fermiers généraux, qui enserra Paris jusqu’en 1860, doubla pendant quelques années les fortifications de Thiers, achevées en 1844 et détruites dans les années 1920, contribuant à la perception de la ville comme cocon, puis joyau protégé par son écrin. À l’époque du « Grand Paris », la « reine des cités » balzacienne, aujourd’hui cernée par le boulevard périphérique, restera le (...) cœur incontestable de la capitale future : ne conserve-t-elle pas intactes l’harmonie urbaine et l’aura culturelle façonnées en son siècle d’or?Paris in the 19th century was the theatre of a trend in urban planning that sought to elevate the city to the heroic status of a modern Babylon or Babel. The city wall erected by the “ fermiers généraux” , which enclosed Paris until 1860, was reinforced for a time by the fortifications completed by Thiers in 1844 and pulled down in the 1920s, thus strengthening perceptions of the city as a cocoon, and later a jewel nestling within its protective casket. Balzac’s “queen of cities”, the Grand Paris now encircled by the ring road, was necessarily the heart of the future capital: had it not preserved the essence of the urban harmony and cultural aura that took shape during its golden era?

The present stage in the development of our society is marked by serious changes in social morality. The building of communism is entering a new stage. The man of the communist future is taking shape and being perfected before our eyes. Under these conditions, the Party - and this was emphasized at its Twenty-Fourth Congress - requires of a worker in the arts a thorough examination of contemporary life and of its hero to the full extent of his talent, and (...) demands that his ethical convictions and awareness of spirit be developed. Since this is the case, it is natural that literary criticism faces new, lofty tasks: tasks of analyzing literature in connection with those economic, societal, and moral processes which characterize social existence today. This was stated clearly both at the Party Congress and in the Resolution of the Central Committee of the CPSU "On Criticism in Literature and the Arts" [O literaturno-khudozhestvennoi kritiki].

Le marché du jeu vidéo explose avec l’émergence d’un nouveau type de jeux et de joueurs appelés occasionnels par opposition au jeu traditionnel sur console. Développeurs et éditeurs adaptent divers types de jeux au format court, simple et non technologique du casual game, mais qu’en est-il du jeu de rôle et d’action exigeant l’exposé et le traitement d’un récit long et complexe ? Après avoir esquissé les enjeux du casual game, nous montrons que seule la mobilisation d’un stéréotype mythique ou (...) légendaire permet l’appropriation d’un scénario à un jeu court : sans en avoir conscience, le joueur connaît scènes et personnages ; aussi peut-il s’immerger directement dans l’action. C’est là retrouver le procédé du « feuilleton-roman » d’aventures du XIXe siècle et pourvoir le casual game d’une ascendance culturelle. Ainsi pourrait-on élargir au jeu vidéo l’essai d’analyser les civilisations à travers leurs jeux comme le souhaitait Roger Caillois.The video games market has been booming since the emergence of “casual” gaming, as opposed to core gaming using consoles. Developers and publishers are adapting different types of games to the short, simple and non-technological casual game format, but how does this affect role-playing and action, which demand an exposé and treatment of long and complex narratives? After outlining the issues arising in casual gaming, we show that appropriating a short game scenario only works when it involves a mythical or legendary stereotype: the game player knows the scene and the characters without thinking about them and can therefore plunge directly into the action. The process harks back to the serial adventure story of the 19th century, which may thus be seen as the ancestor of “casual gaming”. Approaches to the analysis of civilisations through their games could there- fore be extended to encompass video games, as suggested by Roger Caillois. (shrink)
