ItemModeling cultural dynamics(Routledge, 2017)This chapter provides a broad and selective introduction to diverse literatures on computational approaches to cultural dynamics. It explains the social psychological models of cultural dynamics, and then move to two prominent approaches to cultural dynamics— Axelrod's model of cultural dissemination and evolutionary game theoretic approaches to evolution of cooperation. These approaches focus on complementary aspects of cultural dynamics, and that each has unique strengths in dealing with some aspects, but not others. The Axelrod model has been used to explore the dynamics deriving from transmissions of cultural information and the role of drift and to some extent of importation; however, it does not address invention, or most importantly, selection. The evolutionary game theoretic approaches have a unique strength in examining the importance of the selection process in cultural evolution. The chapter discusses how the existing approaches complement each other, and also point to the gap in the existing theory— neither has addressed the process of invention.

ItemCollaborative business process modeling in multi-surface environments(Springer International Publishing, 2017-01-10)Analyzing and redesigning business processes is a complex task which requires the collaboration of multiple actors such as process stakeholders, domain experts and others. Current collaborative modeling approaches mainly focus on modeling workshops where participants verbally contribute their perspective on a process along with ideas on how to improve it. These workshops are supported by modeling experts who facilitate the workshop and translate participants’ verbal contributions into a process model. Being limited to verbal contributions however might negatively affect the motivation of participants to actively contribute. Interactive technology such as smartphones, tablets, digital tabletops and interactive walls can provide opportunities for participants to directly interact with process models. Multi surface environments where different interactive technologies (e.g. display walls, tabletops, tablets, and mobiles) are combined also allow for orchestrating different modes of collaboration. In this chapter we describe an approach that combines different styles of collaboration using various interactive surfaces in a multi surface environment. Testing this approach in three different settings we found indications that interactive technology not only improves involvement by participants but also speeds up workshops and improves the quality of collaboration outcomes. The studies also revealed means for improving the proposed approach.

ItemResearching Death Online(Routledge, 2017)Death now knocks in a digital age. When the time is nigh, whether from natural causes at a ripe age, or from accidents or illness when young, the word goes out through a range of technologies and then various communities gather offline and online. Digital ethnography in this “death” sphere has been growing in form and possibility over the past two decades as various platforms are designed and become occupied with the desires of the living and dying. Online funerals and commemorative activities are now often arranged alongside the perhaps more somber rites of burial or cremation (Boellstorff 2008, 128). Services such as LivesOn promise that we shall be able to “tweet” beyond the grave; members of online communities encounter each other on commemorative online sites where they grieve for a shared friend but never meet each other “in person”; and it is predicted that soon there will be more Facebook profiles of the dead than of the living.
