The results presented in this paper arepart of an empirical studyinto thecurrent usage of groupware and the potential of Computer Supported Cooperative Work (CSCW) for strategic management in large-scale Swiss business enterprises. The results were obtained from a survey conducted among 168 organizations. The study is part of the STRATUM research project, the overall goal of which is to investi...

The workshop focuses on the new work ecologies emerging from implementation and use of information infrastructures in healthcare (IIH). As IIH “grows” through organizational and regulatory mechanisms, CSCW researchers grapple with the shifting nature of healthcare data. CSCW has long been concerned with coordination, cooperation, and communication among interdisciplinary occupations in healthca...

Distributed systems have traditionally tackled the problems associated with the inter-connection of a number of computer systems. Until recently the focus of this research has been on the development of solutions to the technological problems involved. The emergence of Computer Supported Cooperative Working (CSCW) has challenged this technological perspective by focusing on the group-working of...

Up to date, research on computer-supported cooperative work (CSCW) focused mainly on the adaptation of collaboration models used in Intranet to the specificity of Internet. No collaboration model deals with the problem of high amount of data resulting from the high number of collaborators. In this paper, a model of document edition in highly concurrent environments is presented. A document mode...

We have designed a new polycentric knee adopting a hydraulic unit and an intelligent mechanism. The biomechanical parameters of this prototype, such as the stance duration, peak knee flexion angle in stance and swing, peak hip flexion angle, and peak hip extension moments were analyzed at three different cadences (88, 96, 104 steps/min) in three amputees, and then compared to those of polycentr...

Groupware and computer supported cooperative work (CSCW) systems are usually considered collaborative, but some kinds of group activity can actually be competitive. People can have different roles which conflict because they are trying to satisfy different intermediate goals associated with their roles, even though there may appear to be a single consistent goal. This paper examines the differe...

photodegradation of dicamba, an ionizable herbicide, using tio2 supported on hzsm-11 zeolite was investigated. four photocatalysts with different weight percentages (wt%) of tio2 were evaluated: 3%, 10%, 30% and 50%. the effects of the catalyst concentration, the initial ph value and the repeatability of the photocatalytic activity after multiple cycles of reuse were also evaluated. results sho...

The monoid $Cb$ of name substitutions and the notion of finitely supported $Cb$-sets introduced by Pitts as a generalization of nominal sets. A simple finitely supported $Cb$-set is a one point extension of a cyclic nominal set. The support map of a simple finitely supported $Cb$-set is an injective map. Also, for every two distinct elements of a simple finitely supported $Cb$-set, there exists...
