Cet article traite des écrits épistolaires de Helen Maria Williams et Rachel Charlotte Biggs, deux voyageuses anglaises qui se sont rendues en France au cours la Révolution française sous Terreur. L’analyse porte, à travers les représentations l’espace fêtes civiques, sur approches antithétiques idéaux révolutionnaires : premi&#...

Abstra t. Early risk predi tion involves three di erent aspe ts to be onsidered when an automati lassi er is implemented for this task: a) support for lassi ation with partial information read up to di erent time steps, b) support for dealing with unbalan ed data sets and ) a poli y to de ide when a do ument ould be lassi ed as belonging to the relevant lass with a reasonable on den e.

Most juridical systems contain the principle that an act is only unlawful if the agent conducting the act has a `guilty mind' (`mens rea'). Different law systems distinguish di erent modes of mens rea. For instance, American law distinguishes between `knowingly' performing a criminal act, `recklessness', `strict liability', etc. I will show we can formalize several of these categories. The form...

In many real world applications, systematic analysis of rare events, such as credit card frauds and adverse drug reactions, is very important. Their low occurrence rate in large databases often makes it difficult to identify the risk factors from straightforward application of associations and sequential pattern discovery. In this paper we introduce a heuristic to guide the search for interesti...

Suppose that the integers are assigned i.i.d. random variables f! x g (taking values in the unit interval), which serve as an environment. This environment deenes a random walk fX n g (called a RWRE) which, when at x, moves one step to the right with probability ! x , and one step to the left with probability 1 ? ! x. Solomon (1975) determined the almost-sure asymptotic speed v (=rate of escape...

In this paper I review and compare the main sources of information about ka’ulayawaa festivals among Wayùu, an Amerindian people inhabiting in semiarid Guajira peninsula (Northern Colombia Venezuela). For their peculiar mix songs, dances, imitative plays competitive games, inserted into a same festive framework, these are particularly interesting to be studied as expressive metacommentaries (in...

The dynamical evolution of many economic, sociological, biological and physical systems tends to be dominated by a relatively small number of unexpected, large changes ('extreme events'). We study the large, internal changes produced in a generic multi-agent population competing for a limited resource, and find that the level of predictability actually increases prior to a large change. These l...
