A Light Weight Name Service and its use within a Collaborative Editor.

This paper presents the LWNS a light weight name service specially designed for groupware applications and an example of its use. The chosen application, called Duplex, is a collaborative editing environment for users connected through the Internet. It proposes a model based on splitting the document into independent parts, maintained individually and replicated within a distributed kernel. Naming is an important aspect of such application since objects (document parts) are replicated and distributed over the large heterogeneous network. However, this set is small (typically a few dozen elements) and composed of objects whose names are contextual to the document. Replicas are however maintained in heterogeneous file systems with no global naming scheme consistent with the name space of the collaboration.

A Light Weight Name Service and its use within a Collaborative Editor

\begin{abstract} This paper presents the LWNS a light weight name service specially designed for groupware applications and an example of its use. The chosen application, called {\sc Duplex}, is a collaborative editing environment for users connected through the Internet. It proposes a model based on splitting the document into independent parts, maintained individually and replicated within a distributed kernel. Naming is an important aspect of such application since objects (document parts) are replicated and distributed over the large heterogeneous network. However, this set is small (typically a few dozen elements) and composed of objects whose names are contextual to the document. Replicas are however maintained in heterogeneous file systems with no global naming scheme consistent with the name space of the collaboration. This requires a dedicated name service specially designed to solve this problem in large scale distributed applications. \end{abstract

Unusual spread of a penicillin-susceptible methicillin-resistant Staphylococcus aureus clone in a geographic area of low incidence.

We describe the unusual spread of a penicillin-susceptible methicillin-resistant Staphylococcus aureus (MRSA) clone in hospitals in western Switzerland, where the incidence of MRSA is usually low. During a 2-year period, this clone had been responsible for several outbreaks and had been isolated from >156 persons in 21 institutions. Molecular typing by pulsed-field gel electrophoresis (PFGE) demonstrated that all of these isolates belonged to the same clone. In 1 of the outbreaks, involving 30 cases, the clone was responsible for at least 17 secondary cases. In contrast, during the period of the latter outbreak, 9 other patients harboring different MRSA strains, as assessed by PFGE, were hospitalized in the same wards, but no secondary cases occurred. These observations suggest that this clone, compared with other MRSA strains, had some intrinsic factor(s) that contributed to its ability to disseminate and could thus be considered epidemic
