Internet has brought to cultural institutions the chance to use new communication paradigms. In particular the introduction of 3D technology for the network promises to be a powerful means for the diffusion of scientific and humanistic culture, especially for novices that can find in the 3D metaphor a more intuitive paradigm to access cultural information. This work analyzes thc current points ...

Darwin-inspired population thinking suggests approaching culture as a population of items of different types, whose relative frequencies may change over time. Three nested subtypes of populational models can be distinguished: evolutionary, selectional and replicative. Substantial progress has been made in the study of cultural evolution by modelling it within the selectional frame. This progres...

Models of cultural evolution study how the distribution of cultural traits changes over time. The dynamics of cultural evolution strongly depends on the way these traits are transmitted between individuals by social learning. Two prominent forms of social learning are payoff-based learning (imitating others that have higher payoffs) and conformist learning (imitating locally common behaviours)....

In sequential computing, every method of an object can be described in isolation via preconditions and postconditions. However, reasoning in a concurrent setting requires a characterization of all possible interactions across method invocations. Herlihy and Wing [1990]’s notion of linearizability simplifies such reasoning by intuitively ensuring that each method invocation “takes effect” betwee...
