Organizations have been increasingly providing communities of workers with resources, time, physical space and collaborative technologies to enhance the exchange and flow of knowledge and information. In this paper the results of a multi-organizational survey of four work-based communities is presented. These results offer insights into the resource usage, time use for various work activities, and reported individual, community and organizational benefits. A descriptive model is developed and discussed to show the relationships between community participation, time use, and individual and organizational outcomes.

Our study examined WiInf-Central, the "virtual homeplace" of a student community at the University of Hamburg, focusing on the processes of social identity and community building. After a detailed description of WiInf-Central we review our theoretical approaches, based on Social Identity Theory and Communities of Practice, and then set out our research questions and design. Finally, we present and discuss our results, followed by some comments on the theoretical and practical implications of our findings.

In this study, we focus on participants called lurkers, who do not post any messages in an online community such as interactive mailing lists and bulletin board systems. We propose a method of classifying participants including lurkers based on two criteria: what types of actions they take outside the online community, and whether or not the online community affects their thoughts. In addition, based on the results of interviews, we propose hypotheses regarding factors that characterize the categories of lurkers. We conduct a questionnaire survey of all participants in two in-house online communities to verify our method and test the hypotheses. There are a considerable number of lurkers who have a strong and wide influence outside the online community. We conclude that such lurkers cannot be neglected in an evaluation of online communities within a company. We also discuss the possibility of online community management by focusing on not only posters but also lurkers who are indirect contributors to increasing the influence of an online community on its outside environment.

In this paper we describe a current group configuration that is used to support people with cognitive disabilities (hereinafter referred to as "clients") in the workplace. A client receiving face-to-face, often one-to-one assistance from a dedicated human job coach is characteristic of this "traditional" model. We compare this traditional model with other group configurations that are used in cooperative and distributed work practices. In so doing, we highlight requirements that are unique to task support for people with cognitive disabilities. A survey of technologies that have been developed to provide clients with greater levels of independence is then presented. These endeavors often attempt to replace human job coaches with computational cognitive aids. We discuss some limitations of such approaches and then present a model and prototype that extends the computational job coach by incorporating human caregivers in a distributed one-to-many support system.

A number of people are exchanging e-mail messages everyday using mobile phones and PDAs. as well as PCs. E-mail is useful not only for one to-one communication but group communication through mailing lists. However, conventional mailing lists are not as widely used as they should be, because creating and maintaining a mailing list is not an easy task. We propose a simple and powerful mailing list service system called QuickML, with which people can easily create a mailing list and control the member account only by sending e-mail messages. QuickML allows people to enjoy group communication at any place, at any time, and by anyone.

Reconciliating divergent data is an important issue in concurrent engineering mobile computing and software configuration management. Currently, a lot of synchronizers or merge tools perform reconciliations. However, they do not define what is the correctness of their synchronisation. In this paper, we propose to use a transformational approach as the basic model for reasonning about synchronisation. We propose an algorithm and specific transformation functions that realize a file system synchronisation. Unlike classic synchronizers, our synchronizer ensures properties of convergence, causality and intention preservation and is extensible to new data types.

In order to support co-located collaboration, many researchers are now investigating how to effectively augment tabletops with electronic displays. As far back as 1988, orientation was recognized as a significant human factor issue that must be addressed by electronic tabletop designers. As with traditional tables, when people stand at different positions around a horizontal display they will be viewing the contents from different angles. One common solution to this problem is to have the software reorient objects so that any given individual can view them 'right way up.' Yet is this the best approach? If not, how do people actually use orientation on tables? To answer these questions, we conducted an observational study of collaborative activity on a traditional table. Our results show that the strategy of reorienting objects to a person's view is overly simplistic: while important, it is an incomplete view of how people exploit their ability to reorient objects. Orientation proves critical in how individuals comprehend information, how collaborators coordinate their actions, and how they mediate communication. The coordinating role of orientation is evident in how people establish personal and group spaces, and how they signal ownership of objects. In terms of communication, orientation is useful in initiating communicative exchanges and in continuing to speak to individuals about particular objects and work patterns as collaboration progresses. The three roles of orientation have significant implications for the design of tabletop software and the assessment of existing tabletop systems.

In this paper, we present results from the study of a free software development virtual organization, the GNU Enterprise (GNUe) project, and how they develop software in a globally distributed free software development project. In particular, examples of how they mitigate and resolve conflict are presented. Conflict arises over the use of a non-free tool to create GNUe graphic, and over the use of a non-free tool for GNUe documentation. The GNUe developers resolve the conflict using internet relay chat (IRC), threaded email discussions, and community digests. We characterize the GNUe developers as an occupational subculture within the occupational community of free/open source software (F/OSS) developers and show how the beliefs in free software and freedom of choice, and values in cooperative work and community assist GNUe contributors in mitigating and resolving conflict. In addition, we show how, despite fluctuating boundaries of membership in a virtual organization, daily discussions on the GNUe IRC serve to build and perpetuate the global community of GNUe contributors as well as F/OSS developers in general.

Genre analysis is an approach to study organizational structures, focusing on communication patterns, which can be applied to the specific context of meetings. This research investigates the impact of genre analysis on the design of meetingware. The paper describes how genre analysis was used to develop meetingware for several organizations and meeting genres. The paper covers the whole design process, from genre elicitation to validation. The obtained results indicate that genre analysis impacts meetingware design in five major dimensions: organizational integration, situated nature, meeting lifecycle view, focus on communication patterns, and preservation of the meeting context.

Heterogeneity aspects in mobile collaborative systems, such as differences in user's interest, semantic conflicts across different domains and representations, and disparate device capabilities, cause difficulties in developing software applications. One of the key problems for collaborative applications is maintaining a consistent shared state. In this paper, we describe a framework that manages several aspects of heterogeneity to maintain consistency across the collaborating sites. We assume graph data structure for application state representation. Our framework is based on structural and semantic mappings between graph structures. The mapping can be customized to meet different requirements through user-defined policies and rules. An important constraint is efficient use of scarce system resources. We describe several applications built using the framework to collaboratively share XML documents. The XML documents in our case are 2D/3D representations of virtual worlds. We also show the performance results of our framework which demonstrate its feasibility for mobile scenarios.
