Title Diversity of statistical modeling approaches in multilevel social network analysis
Author BRAILLY Julien, LAZEGA Emmanuel
Keywords Affiliation, ERGM, Multilevel analysis, Multilevel substructure, Social network, Stochastic network analysis
Topic None
Abstract This article presents some different statistical approaches for multilevel network analysis including the multilevel-p2 models for egocentric network data analysis and the Exponential Random Graph Models (ERGMs) for neo-structural multilevel data. First, we study the stochastic models based on dependence assumptions between dyads, including a hierarchical approach using jointly different networks studies. After presenting the ERGMs, we investigate how multilevel dependence may be introduced in them. We conclude then by the Robins and Wang formalization [2010] which seems to be the most successful attempt to treat the dependencies between the two partially nested networks of different levels.

Title Log-periodic expansions of Russian and Roman territories
Author BRISSAUD Ivan, CHALINE Jean, GROU Pierre, NOTTALE Laurent
Keywords Evolution, Roman territories, Russian territories, Universality
Topic None
Abstract Log-periodic expansions of Russian and Roman Territories Territories of the Russian Empire and of the Roman Empire expanded over a period of several centuries, but independently of the time and of the geographic areas. Their evolution took the form of a series of jumps followed by a pause indicating a deceleration mode from a critical time. Such a system could be described by a log-periodic law. This type of behaviour can observed in the chronology of various phenomena (species evolution of echinoderms, dinosaurs, rodents, equids, primates and hominids; human ontogeny, financial crashes and earthquakes…).

Title A proof theoretical framework for argumentation modeling
Author QUATRINI Myriam, FOUQUERE Christophe
Keywords Argumentation, Dialogue acts, Formalization of dialogues, Linear logic, Ludics
Topic None
Abstract In this paper, we are interested in argumentative dialogues, we continue the approach introduced by Lecomte et Quatrini [2010], who proposed a formalization of dialogues within the framework of Ludics. We illustrate our proposal in two very different cases: the controversies exemplifying Schopenhauers stratagems in [Schopenhauer 1830] and an adjudication dialogue studied by Prakken [2008].
