The social behaviour of interacting individuals is typically analysed as a series of multiple dyadic (pair-wise) interactions, rather than a network of interactions among multiple individuals. However, in species where parents feed dependant young, interactions within families nearly always involve more than two individuals simultaneously. Such social networks of interactions at least partly reflect conflicts of interest over the provision of costly parental investment. Consequently, variation in family network structure reflects variation in how conflicts of interest are resolved among family members. Despite its importance in understanding the evolution of emergent properties of social organization such as family life and cooperation, nothing is currently known about how selection acts on the structure of social networks. Here, we show that the social network structure of broods of begging nestling great tits Parus major predicts fitness in families. Although selection at the level of the individual favours large nestlings, selection at the level of the kin-group primarily favours families that resolve conflicts most effectively

L'educació creadora

Aquest treball està basat en un projecte d'investigació envers l'expressió lliure, a partir dels conceptes que ens proporciona l'educació creadora. El seu objectiu principal és donar a conèixer aquesta visió per tal d'afavorir la reflexió i el plantejament d'altres vies educatives. Per a fer-ho, he assistit a conferències, formacions i tallers que sustenten l'àmbit més teòric. En relació a la part empírica del treball, he realitzat un projecte en comú amb la facultat de comunicació audiovisual, el qual es desenvolupa a partir d'un documental que representa el resultat final de la recerca
