Here we are working in the measurement theory framework. The appropriate measurement method is to use the successive intervals of Adams and Messick, which are well suited for univariate conditions when responses are given in relation to one descriptive variable; here we examine the multivariate extension, the first formal properties and the possibility to explicit the interaction between variables. Number 188, Winter 2009 Language   French Read the article Title «The battle of the swimmers». Illustration of a conflict between individual preferences and the collective interest Author COLLARD Luc, LOYER Frédéric Keywords Equilibrium, Experimental game theory, Social contract, The prisoner's dilemna Topics Decision Theory, Equilibrium, Game Theory, Social Psychology Abstract How do persons behave «in the flesh» when they are instructed to choose between the unsatisfactory caution of a selfish decision, and the risky satisfaction of an altruistic decision? We ask 64 adult sportsmen to play a typical game «the prisoner's dilemna» in the swimming pool. The "battle between the swimmers" shows that, the specialists of combat sport who are the most selfish used to the systematic fighting spirit. Their expected gain is greater than that of the altruistic players who are nevertheless driven by a respectable moral sense (p<0,05 in T of Student). In vivo, Nash equilibrium [1950] is stronger than Harsanyi equilibrium [1977]. Number 188, Winter 2009 Language   French Read the article Title Log periodic evolution of monastic orders Author BRISSAUD Ivan Keywords Log periodicity law, Monastic orders, Temporal tree structure Topics History, Periodic functions, Time Series, Trees Abstract After the VIth century various religious and monastic orders, all of which influenced the social, economical and political life of their time, succeeded each other. These orders all attempted to promote a stricter respect of the fundamental (religious) rules. But failing to achieve this goal, each order was supplanted by a new one. The succession of jumps in this evolutionary tree shows an acceleration between Benedictine up to Mendicant orders (XIIIth century) similar to what has been observed for various phenomena (evolution of hominidae, financial market crash, earthquake.). This suggests that it might be relevant to apply a log periodic system to this chronology. The deduced values of the critical times and of the self similarity factor are Tc = 1290+/-40 and g = 2,14+/-0,30. No deceleration steps are observed after Tc. This could be explained by the predominance of the secular clergy. Number 188, Winter 2009 Language   French Read the article Title Gianluca Manzo, La spirale des inégalités.
