Against the prior view that primate communication is based only on signal decoding, comparative evidence suggests that primates are able, no less than humans, to intentionally perform or understand impulsive or habitual communicational actions with a structured evaluative nonconceptual content. These signals convey an affordance-sensing that immediately motivates conspecifics to act. Although h...

The growing use of animation in Web pages testifies to the increasing ease with which such multimedia components can be created. This trend indicates a commitment to animation that is often unmatched by the skill of the implementers. The present paper details a set of ten commandments for web animation, intending to sensitise budding animators to key aspects that may impair the communicational ...

This paper proposes a new scheme for partially blind signature based on the difficulty in solving the discrete logarithm problem. Under the assumption of the generic model, random oracle model, and intractable ROS-problem, this paper formally proves that the proposed scheme is secure against one-more signature forgery under the adaptively parallel attack. Previous schemes using two signing equa...

The recent developments in telecommunications and the spreading of the Internet culture, have made closer the possibility of having communicational resources as the once envisioned by science fiction, not too far ago. The use of video in telecommunication is already a real possibility not only for corporations and the aero-spatial industry, but also for any person with not necessarily very soph...

The ever-growing amount of documents (electronic or other) has increased the value of abstracts, and abstracting systems and services, as instruments for concentrating and supplying relevant information. Ongoing research in different disciplines, with abstracting as the common subject matter, points to the usefulness of the paradigm concept. This perspective would provide the coherence necessar...

We present in this paper our reflections about the requirements of new architectures and languages for the Web, confronted with the ones emerging from qualified scientists such as Mc Carthy [1] and Wegner [2]. The contribution highlights if and how these reflections may be concretely realized by means of extensions of non standard models and tools that we have already experimented and that appe...

We present a formal-model of awareness-systems founded upon the focus and nimbus model of Benford et al [2] and of Rodden [19]. The model aims to provide a conceptual tool for reasoning about this class of systems. Our model introduces the notions of aspects, attributes and resources in order to expose the communicational aspects of awareness-systems. We show how the system enables reasoning ab...

We report results of lexical accommodation studies involving three different interpretation settings: human-human monolingual; human-interpreted bilingual; and machine-interpreted bilingual. We found significant accommodation in all three conversational settings, with the highest rate in the human-interpreted setting. There is evidence for longrange mutual accommodation in that setting, as comp...
