Social presence, or the subjective experience of being present with another existing person, varies with the interaction medium. In general, social presence research has mainly focused on uni-directional aspects of each exchanged message, not on bidirectional interactions. Our primary purpose is to introduce such bidirectional evaluation by quantifying the degree of social presence with a few statistical measures. To this end, we developed a software called “TypeTrace” that records all keystrokes of online chat interactants and reenacts their typing actions and (...) analyzed the results from different chat conditions, mainly focusing on the characterization of bi-directional interactions. We also compared the chat interaction patterns with the patterns from phone call datasets to investigate the difference of live communication in different media. The hypothesis of the experiment was that either richness or concurrency of communication is important for organizing social presence. Richness is defined by the variety of information at a time in communication and the concurrency is the number of temporal thread being processed at the same time. Our results show that when we merely increase the richness of information by presenting the typing process, the cognition of others' presence does not significantly increase. However, when the information concurrency is augmented by introducing the transmission of realtime text, we found that the transfer entropy between the interactants becomes considerably higher, and the social presence and emotional arousal, intimacy increased. High transfer entropy was also observed in the phone call dataset. This result shows that the mere augmentation of information richness does not necessarily lead to increased social presence, and concurrent communication is another critical factor for fostering vivid conversation in digital environments.

This paper compares two case studies of prepaid card technology where the same ``technology'' is applied in two separate industries, the public telephone industry and the pachinko game industry in Japan. The different outcomes in the two areas are analyzed in terms of the functions of what is introduced here as ``socio-technological aggregates''. A socio-technological aggregate is composed of an initiating innovator component and heterogeneous components necessary for the technology to function in a given society. The analysis of technology as (...) an STA gained insights from the phenomena of aggregates in other areas: the socio-literary aggregate created by Russell McCormmach in Night Thoughts of a Classical Physicist; by the ``collage'' phenomenon created by Picasso, Braque; and others, and the socio-musical aggregates of John Cage. Two important aspects of an STA are: the bonding/managing component that dictates how a technology is applied; and the evaluator component that triggers multimodality. (shrink)

The genesis for this volume was in the bombing of Japan during World War II, where the author, as a young boy, watched the bombers overhead, speculating about the lives of the pilots and their relationship with those huddled on the ground._ From this disturbing diorama, Professor Hiroshi Kojima, the translator of Martin Buber into Japanese, unfolds a new approach to Buber's “I-Thou” relation, drawing upon insights from Husserl, Heidegger, and others in the tradition of continental philosophy to extend (...) and deepen Buber's thought. In chapters that reflect upon a wide range of phenomena—from religion, science, and technology, to imagination, embodiment, and power—Professor Kojima articulates a conception of what it means to be a human being that stands as an alternative to atomism and alienation of the modern world. Analyses of haiku and other aspects of Japanese culture demonstrate how Kojima's theory can illuminate the spiritual traditions of both East and West. Original in its thought and revealing in its insight into Japanese thought and culture, _Monad and Thou__ represents the life's work of one of Japan's great thinkers. (shrink)

This paper proposes a class of independence axioms for simple acts.

Furthermore, in order to provide the axiomatization of simple acts, we generalize Kajii et al. into an infinite state space. Our axiomatization theorem relates (...) Choquet expected utility to multi-prior expected utility through the core of a capacity that is explicitly derived within our framework. Our result in this paper also derives Gilboa, Eichberger and Kelsey, and Rohde as a corollary. (shrink)
