No full textAgent Based Modelling is the most interesting and advanced approach for simulating a complex system: in a social context, the single parts and the whole are often very hard to describe in detail. Besides, there are agent based formalisms which allow to study the emergency of social behaviour with the creation and study of models, known as artificial societies. Thanks to the ever increasing computational power, it's been possible to use such models to create software, based on intelligent agents, which aggregate behaviour is complex and difficult to predict, and can be used in open and distributed systems. Data mining is born in the last decades in order to help users in finding useful knowledge from the otherwise overwhelming amount of data available nowadays from the web and the data collected every day by companies. Data Mining techniques can therefore be the keystone to reveal non-trivial knowledge expressed by the initial assumption used to build the micro-level of the model and the structure of the society of agents that emerged from the simulation

El estudio filosófico de las virtudes en el pensamiento contemporáneo
No full textLa llamada ‘ética de la virtud’ constituye un destacable marco de reflexión y análisis en el campo de la filosofía moral contemporánea. Presentaremos aquí las especulaciones de tres filósofos contemporáneos acerca de las virtudes. Veremos cómo Peter T. Geach, Alasdair McIntyre y Jean-Luc Marion, respectivamente, se aproximan a las virtudes y analizan su naturaleza factual y antropológica así como su función teleológica, cosmológica y cultural dentro de los acuerdos intersubjetivos de caracteres lingüísticos, epistémicos y jurídico-legales, garantizados por los miembros de una comunidad dada.Fil: Le Gall, Sylvain.

Are gall midge species (Diptera, Cecidomyiidae) host-plant specialists?
No full textEspécies de moscas galhadoras (Diptera, Cecidomyiidae) são especialistas em plantas hospedeiras? Apesar do elevado número de espécies da fauna de insetos indutores de galhas na região Neotropical, muito pouco espécies foram descritas. Por outro lado, o morfotipo da galha associado com a espécie da planta hospedeira é em todo o mundo amplamente utilizado como um indicador da espécie de inseto indutor. Este estudo revê as espécies de cecidommídeos descritos e suas galhas para verificar a generalização do uso da morfologia da galha como indicador da espécie de cecidomíideo na fauna brasileira. Nós compilamos dados biológicos e taxonômicos de 196 espécies de cecidomiídeos em 128 espécies de plantas no Brasil. Noventa e dois porcento destas espécies foram monófagas, induzindo galhas em uma única espécie de planta hospedeira, enquanto somente 5,6% das espécies foram oligófagas, induzindo galhas em mais de uma espécie de planta do mesmo gênero. Somente quatro espécies induzem galhas em espécies de plantas de gêneros diferentes. Nós concluímos que o morfo-tipo da galha associado com a espécie da planta hospedeira e com o órgão
atacado são indicadores confiáveis da espécie de insetos indutores de galhas.Are gall midge species (Diptera, Cecidomyiidae) host plant specialists? Despite the speciose fauna of gallinducing
insects in the Neotropical region, little is known about their taxonomy. On the other hand, gall morphotypes
associated with host species have been extensively used as a surrogate of the inducer species worldwide. This study
reviewed the described gall midges and their galls to test the generalization on the use of gall morphotypes as surrogates
of gall midge species in the Brazilian fauna. We compiled taxonomic and biological data for 196 gall midge species
recorded on 128 host plant species. Ninety two percent of those species were monophagous, inducing galls on a single
host plant species, whereas only 5.6% species were oligophagous, inducing galls on more than one congeneric host plant
species. Only four species induced galls on more than one host plant genus. We conclude that gall morphotypes associated with information on the host plant species and attacked organs are reliable surrogates of the gall-inducing species
