This paper relates the discussion of articulation work (and of disarticulation) to issues of the creation and control of collective communication spaces. Four different types of settings are examined occupationally segregated terrains, emergency situations, scarce-resource settings and performance-intensive settings. What is articulated in such settings is seen as dependin~l on the properties o...

This article gives an analysis of topological and homological properties for loop spaces of configuration spaces. The main topological results are given by certain choices of product decompositions of these spaces, as well as “twistings” between the factors. The main homological results are given in terms of extensions of the “infinitesimal braid relations” or “universal YangBaxter Lie relations”.

This paper introduces the concept of an approach merotopological space and studies its categorytheoretic properties. Various topological categories are shown to be embedded into the category whose objects are approach merotopological spaces. The order structure of the family of all approachmerotopologies on a nonempty set is discussed. Employing the theory of bunches, bunch completion of an app...

In this abstract, we try to build a bridge between Guarino’s notion of quality fields/patterns and the Theory of Conceptual Spaces (CS). For that, we employ an extension of CS called Holistic-Structure Spaces.

Biological macromolecules, living in the confines of a cell, often adopt conformations that are unlikely to occur in free space. In this paper, we investigate the effects of confinement on the shape of a semiflexible chain. Results of Monte Carlo simulations show the existence of a shape transition when the persistence length of the polymer becomes comparable to the dimensions of the box. An or...

This paper investigates an important, yet under-researched topic in CSCW, namely shared, or common, information spaces. We provide some background to work in the area, and then proceed to examine features of such spaces. The work involved in both putting information in common, and in interpreting it, has often not been sufficiently recognized. Through a number of situations we discuss the influ...
