This often requires disclosing and sharing personal information via tools such as instant messaging systems and can conflict with the users' wishes for privacy. In this paper we present an initial study investigating this trade-off and discuss implications for the design of instant messaging systems. We present the functionality and design of the PRIMIFaces instant messaging prototype supporting flexible identity management and selective information disclosure. 2008 urn:nbn:de:gbv:wim2-20080314-13452 10.25643/bauhaus-universitaet.1275 Professur Computergestütztes kooperatives Arbeiten OPUS4-745 Bericht Gross, Tom; Oemig, Christoph COBRA: A Constraint-Based Awareness Management Framework The effective and efficient cooperation in communities and groups requires that the members of the community or group have adequate information about each other and the environment. In this paper, we outline the basic challenges of managing awareness information. We analyse the management of awareness information in face-to-face situations, and discuss challenges and requirements for the support of awareness management in distributed settings. Finally, after taking a look at related work, we present a simple, yet powerful framework for awareness management based on constraint pattern named COBRA. 2005 urn:nbn:de:gbv:wim2-20111215-7451 10.25643/bauhaus-universitaet.745 Professur Computergestütztes kooperatives Arbeiten OPUS4-747 Bericht Gross, Tom; Oemig, Christoph 'Sorry, Pal---What I See is Usually Not What You Get!': The Role of Reciprocity in Information Disclosure For efficient distant cooperation the members of workgroups need information about each other. This need for information disclosure often conflicts with the users' wishes for privacy. In the literature often reciprocity is suggested as a solution to this trade-off. Yet, this conception of reciprocity and its enforcement by systems does not match reality. In this paper we present our study's major findings investigating the role of reciprocity among which we found that participants greatly disregarded the above conception. Additionally we discuss their significant implications for the design of systems seeking to disclose personal information. 2006 urn:nbn:de:gbv:wim2-20111215-7474 10.25643/bauhaus-universitaet.747 Professur Computergestütztes kooperatives Arbeiten
