This paper investigates a puzzling feature of social conventions: the fact that they are both arbitrary and normative. We examine how this tension is addressed in sociological accounts of conventional phenomena. Traditional approaches tend to generate either synchronic accounts that fail to consider the arbitrariness of conventions, or diachronic accounts that miss central aspects of their norm...

Software modeling is an important activity for maintenance since it can facilitate the software comprehension as well as the understanding of its activities towards evolution, correction and adaptation. In this sense, maintainability and its subcharacteristics as presented in the ISO/IEC 9126 standard should be incorporated to the artifacts produced in the modeling activity aiming at designing ...

Vision perception is ambiguous and visual arts play with these ambiguities. While perceptual ambiguities are resolved with prior constraints, artistic ambiguities are resolved by conventions. Is there a relationship between priors and conventions? This review surveys recent work related to these ambiguities in composition, spatial scale, illumination and color, three-dimensional layout, shape, ...

In this paper we identify the spreading components required to design convention emergence mechanisms. We have empirically tested the effectiveness of our approach to emerge conventions in scenarios where the space of conventions is large. Moreover, we identify their shortcomings when used for the emergence of stable, global conventions despite unreliable communications (be them because of nois...

If you have been driving in Europe recently, you must have had that strange feeling. You see a sign that says 'Deutschland', or 'France', or 'España', and just drive through. No customs barrier, no passport control—just a sign. You say 'Ah!' and carry on; the sign could be a hundred yards further out and it would make no difference. Yet by crossing that line you enter a different world-district...
