Abstract The scope of CSCW has been a topic of sporadic debate for many years, but in a programmatic article from 2005, three esteemed CSCW researchers – Andy Crabtree, Tom Rodden, and Steve Benford – now forcefully argue that CSCW should ‘move its focus away from work’. It is thus time to reconsider CSCW, to rethink what it is and why it might be important. This paper focuses on CSCW’s scope: ...

This paper reports fieldwork from an organization in the pnnt industry, examining a workflow system introduced to the shopfloor. We detail the indigenous methods by which members order their work, contrast this with the order provided by the system, and describe how members have attempted to accommodate the two. Although it disrupted shopfloor work, the system's use was a contractural requireme...

The combination of Multimedia and Computer Supported Cooperative Work (CSCW) poses a significant challenge to the computing and communication infrastructure. Although local multimedia applications offer sophisticated capabilities, multimedia in communications is usually limited to more or less trivial picturephone functionality. Based on the idea of window sharing, our Joint Viewing and Teleope...

Computer-Supported Cooperative Work (CSCW) is a research field where the role played by individuals as members of groups is fundamental. The human being is not considered as an individual entity, but it is considered as a being embedded into the society, where he works and interacts. From the beginning, many CSCW systems have arisen. Some taxonomies appeared in order to find a way to classify a...

Alexandrov’s Theorem states that every metric with the global topology and local geometry required of a convex polyhedron is in fact the intrinsic metric of some convex polyhedron. Recent work by Bobenko and Izmestiev describes a differential equation whose solution is the polyhedron corresponding to a given metric. We describe an algorithm based on this differential equation to compute the pol...

A generalization of the classical one-dimensional Darboux transformation to arbitrary n-dimensional oriented Riemannian manifolds is constructed using an intrinsic formulation based on the properties of twisted Hodge Laplacians. The classical two-dimensional Moutard transformation is also generalized to non-compact oriented Riemannian manifolds of dimension n ≥ 2. New examples of quasi-exactly ...

The best extant statement of the epistemic regress problem makes assumptions that are too strong. An improved version assumes only that that reasons require support, that no proposition is supported only by endless regresses of reasons, and that some proposition is supported. These assumptions are individually plausible but jointly inconsistent. Attempts to explain support by means of unconcept...

The classical Waring problem deals with expressing every natural number as a sum of g(k) k powers. Similar problems were recently studied in group theory, where we aim to present group elements as short products of values of a given word w 6= 1. In this paper we study this problem for Lie groups and Chevalley groups over infinite fields. We show that for a fixed word w 6= 1 and for a classical ...

We consider positive de nite and radial functions. After giving general results concerning the smoothness of general positive de nite and radial functions, we investigate the class of compactly supported, positive de nite, and radial functions, where every function consists of a univariate polynomial within its support. Especially, we show that these functions necessarily possess an even number...
