This paper presents an ethnographic analysis of the nature and role of gestural action in the performance of a remote collaborative physical task. The analysis focuses on the use of a low-tech prototype gesturing system, which projects unmediated gestures to create a mixed reality ecology that promotes awareness in cooperative activity. CSCW researchers have drawn attention to the core problem ...

We propose in this paper, an approach for defining in a systematic manner, ways-ofworking providing guidelines for the development of information systems. It is a modelling approach in which a given way-of-working is constructed by instantiation of a way-of-working model allowing to deal with a large variety of situations in a flexible, decision-oriented manner. The paper presents the way-of-wo...

The revision brings all the material up to date and includes the standards recently adopted by the National Nutrition Committee. "Probably the most complete and simply w...

Euler’s partition theorem says that the number of ways to partition an integer into odd parts is the same as the number of ways to partition it into distinct parts. We show how the combinatorics of “l-sequences” gives rise not only to a generalization of Euler’s theorem (discovered by Bousquet-Melou and Eriksson in 1997), but also to a generalization of Sylvester’s bijective proof. This is join...

Self-evidencing describes the purported predictive processing of all self-organising systems, whether conscious or not. in itself is therefore not sufficient for consciousness. Different systems may however be capable self-evidencing different, specific and distinct ways. Some these ways can matched up with, explain, several properties This carves out a distinction nature between those that are...

Possible worlds semantics has been very useful in modelling not only the intensionality of necessity and possibility, future and past. It has also found its place in modelling the intentionality of propositional attitudes like belief and knowledge. There is something fruitful in analysing a belief as a set of possible worlds. The belief is the set of possible worlds in which the belief is true....

One may remember or forget these messages but briefly one takes them in, and for a moment they stimulate the imagination by way of either memory or expectation. The publicity image belongs to the moment. We see it as we turn a page, as we turn a corner, as a vehicle passes us. Or we see it on a television screen while waiting for the commercial break to end. Publicity images also belong to the ...
