Making Space for Stories: Ambiguity in the Design of Personal Communication Systems

Pervasive personal communication technologies offer the potential for important social benefits for individual users, but also the potential for significant social difficulties and costs. In research on face-to-face social interaction, ambiguity is often identified as an important resource for resolving social difficulties. In this paper, we discuss two design cases of personal communication systems, one based on fieldwork of a commercial system and another based on an unrealized design concept. The cases illustrate how user behavior concerning a particular social difficulty, unexplained unresponsiveness, can be influenced by technological issues that result in interactional ambiguity. The cases also highlight the need to balance the utility of ambiguity against the utility of usability and communicative clarity.Comment: 10 page

Apparatgeist and Mobile Communication: Considering Interpersonal Communication Practices

Mobile communication is embedded into our daily life increasing our connection to social networks. The development of mobile communication occurred during the second half of the twentieth century and has become domesticated into everyday life. One consequence of the widespread adoption of mobile communication device use is an increase in connectivity. This increase in connection has led to a shift in interpersonal relationships. People now must be aware of when to connect and disconnect to develop meaningful relationships in private, public, and social realms. This project seeks an understanding of how the consequence of increased connectivity and the development of the socio-logic of perpetual contact shapes interpersonal relationships. The project discusses concepts from relational dialectics theory, ideas from Hannah Arendt concerning technology relating to the human condition and private, public, and social realm, and dialogic ethics approach to using mobile communication. James E. Katz and Mark A. Aakhus’ theory of Apparatgeist provides a groundwork for understanding the consequences of mobile communication within the ‘Spirit’ of the historical moment. Mobile communication devices are a defining feature of contemporary life and should be used responsibly in a way that respects the importance of practicing dialogue and engaging in rhetorical listening and understanding

A Theory-Driven Design Framework for Social Recommender Systems

Social recommender systems utilize data regarding users’ social relationships in filtering relevant information to users. To date, results show that incorporating social relationship data – beyond consumption profile similarity – is beneficial only in a very limited set of cases. The main conjecture of this study is that the inconclusive results are, at least to some extent, due to an under-specification of the nature of the social relations. To date, there exist no clear guidelines for using behavioral theory to guide systems design. Our primary objective is to propose a methodology for theory-driven design. We enhance Walls et al.’s (1992) IS Design Theory by introducing the notion of “applied behavioral theory,” as a means of better linking theory and system design. Our second objective is to apply our theory-driven design methodology to social recommender systems, with the aim of improving prediction accuracy. A behavioral study found that some social relationships (e.g., competence, benevolence) are most likely to affect a recipient’s advice-taking decision. We designed, developed, and tested a recommender system based on these principles, and found that the same types of relationships yield the best recommendation accuracy. This striking correspondence highlights the importance of behavioral theory in guiding system design. We discuss implications for design science and for research on recommender systems

Taking things into account: learning as kinaesthetically-mediated collaboration

This paper presents research on participant learning processes in challenge course workshops using the framework known as Cultural-Historical Activity Theory (CHAT). CHAT views learning as a shared, social process rather than as an individual event. Participants\u27 experiencing and learning was mediated by the physical and social conditions of the experience and by the contributions of other participants. The concept of mediation suggests that the meaning participants make of experience is not an individual event, but instead is enacted as a creative, collaborative process using cultural and institutional tools. The recognition that people\u27s physical, social and reflective learning processes are mediated, challenges longstanding assumptions about the radical autonomy of learners, about ‘direct experience,’ and about the centrality of independent, cognitive reflection in experiential learning. Empirical data showing processes of mediation are presented, and the implications for research and theory are discussed

Your Privacy Is Your Friend's Privacy: Examining Interdependent Information Disclosure on Online Social Networks

The highly interactive nature of interpersonal communication on online social networks (OSNs) impels us to think about privacy as a communal matter, with users' private information being revealed by not only their own voluntary disclosures, but also the activities of their social ties. The current privacy literature has identified two types of information disclosures in OSNs: self-disclosure, i.e., the disclosure of an OSN user's private information by him/herself; and co-disclosure, i.e., the disclosure of the user's private information by other users. Although co-disclosure has been increasingly identified as a new source of privacy threat inherent to the OSN context, few systematic attempts have been made to provide a framework for understanding the commonalities and distinctions between self- vs. co-disclosure, especially pertaining to different types of private information. To address this gap, this paper presents a data-driven study that builds upon an innovative measurement for quantifying the extent to which others' co-disclosure could lead to actual privacy harm. The results demonstrate the significant harm caused by co-disclosure and illustrate the differences between the identity elements revealed through self- and co-disclosure
