Modern healthcare's need for knowledge sharing and bridging the researchpractice-gap requires new forms of collaboration, in which clinicians of varying clinical and research expertise work together over geographical and organisational borders. To support such distributed communities of practice (CoPs), an understanding of their collaboration processes, outcomes, challenges, and enablers is needed. The paper examines these issues through a case study of a long-running CoP, the Swedish Oral Medicine Network (SOMNet). SOMNet's main form of collaboration is monthly telephone conference meetings centred on case consultations. Cases are submitted by the clinicians via a Web-based system. The methods used were interviews, observations, and a questionnaire.The work adds to previous research by studying a distributed CoP explicitly focused on supporting the transfer of scientific results from researchers to practitioners.We found that the regular meetings give a rhythm to the community. The centrality of cases means an immediate benefit for the submitter while the share an overarching goal of general improvement and harmonisation of patient care.However, the present study focuses on distributed collaboration where there are more than two types of participants, which sets it apart from the common format of teleconsultations. The studied distributed CoP makes the case discussions available to a larger group of clinicians, while adding challenges related to handling a larger and heterogeneous group. This study also has commonalities with the format of the MDTM, but without the emphasis on the coordination between the different roles and disciplines involved in caring for a specific patient, and with more loosely coupled participants.Within the studied collaboration, there is little variation with respect to the discipline, but much variation in the other aspects, such as degree of specialisation, experience, focus on clinical work or on research, access to external evidence, location, and level of partici- 2004).

DATA GAMESWe would like to add to the ever-growing list of things that can be done with games by proposing, discussing and exemplifying data games. A data game is a game that allows the player(s) to explore data that is derived from outside the game, by transforming the data into something that can be played with. In other words, games as a form of interactive data visualisation. We believe that games, through their procedural and interactive nature, can provide possibilities for visualisation over and beyond traditional methods. Data games differ from most other types of serious games in that they do not (intentionally) have an agenda; they are tools for the player to use to explore data with as few constraints as possible.

Abstract-With increasing amounts of open data, especially where data can be connected with various additional information resources, new ways of visualizing and making sense of this data become possible and necessary. This paper proposes, discusses and exemplifies the concept of data games, games that allow the player(s) to explore data that is derived from outside the game, by transforming the data into something that can be played with. The transformation takes the form of procedural content generation based on real-world data. As an example of a data game, we describe Open Data Monopoly, a game board generator that uses economic and social indicator data for local governments in the UK. Game boards are generated by first collecting user input on which indicators to use and how to weigh them, as well as what criteria should be used for street selection. Sets of streets are then evolved that maximize the selected criteria, and ordered according to "prosperity" as defined subjectively by the user. Chance and community cards are created based on auxiliary data about the local political entities.

Abstract. SOMWeb is a Web-based system designed to support a clinical community of practice. Their collaboration centers on the discussion of oral medicine cases at monthly telephone conferences. SOMWeb facilitates the collaboration by, e.g., providing forms for entering case data and by providing easy access to current and previous cases. Through interviews, log analysis, and analysis of cases several impacts on the collaboration can be identified. These include the impact on membership, case submission, chairpersonship, and the community of practice as a whole. Further, it can be concluded that the rhythm provided by the telephone conferences ensures that the system has regular use.
