New methods and new systems are needed to lter or to selectively distribute the increasing volume of electronic information being produced nowadays. An e ective information ltering system is one that provides the exact information that ful lls a user's interest with the minimum e ort by the user to describe it. Such a system will have to be adaptive to the user changing interest. In this paper ...

This paper introduces the narrative network as a device for representing patterns of “technology in use.” The narrative network offers a novel conceptual vocabulary for the description of information and communication technologies (ICTs) and their relationship to organizational forms. We argue that as ICTs have become increasingly modular and recombinable, so have organizational processes and f...

In this paper we study topology of the variety of closed pla-nar n-gons with given side lengths l1,. .. , ln. The moduli space M ℓ where ℓ = (l1,. .. , ln), encodes the shapes of all such n-gons. We describe the Betti numbers of the moduli spaces M ℓ as functions of the length vector ℓ = (l1,. .. , ln). We also find sharp upper bounds on the sum of Betti numbers of M ℓ depending only on the num...

The Village Voice project is a study of the efficacy of a localized ontology in the dissemination of narrative. It seeks to understand how community members can articulate their lives in ways that allow each other to reflect on the makeup of their overall community, and how they represent their community's needs to those outside of the group. I utilize a knowledge model, or ontology, created by...

The following narrative was written by Nancy MacRae, an occupational therapy professor at the University of New England. Her experience from the other side of the health care relationship reminds us all how very different the client/patient view is and what an invaluable learning opportunity this perspective can afford. We can all be humbled by the real life client role, yet the learning and di...

BACKGROUND Dissemination of psychotherapeutic modules to local counselors seems a key requirement for coping with mental health disasters in conflict regions. We tested a train-the-trainer (TTT) dissemination model for the treatment of posttraumatic stress disorder (PTSD). METHODS We randomly assigned widowed or orphaned survivors of the 1994 Rwandan genocide with a PTSD diagnosis to narrativ...

Using the example of a failed software implementation, we discuss the role of artifacts in shaping organizational routines. We argue that artifact-centered assumptions about design are not well suited to designing organizational routines, which are generative systems that produce recognizable, repetitive patterns of interdependent actions, carried out by multiple actors. Artifact-centered assum...

BACKGROUND Sharing interim data, results or result extrapolations is an important issue that can affect trial integrity. The different ways in which Data Safety Monitoring Boards (DSMBs) share interim results with non-DSMB members and the acceptability of such practices are poorly understood. Our objective was to undertake a narrative review specifically on what kind of interim results, if any,...
