At a time of increased social usage of net and collaborative applications a robust and detailed theory of social presence could contribute to our understanding of social behavior in mediated environments, allow researchers to predict and measure differences among media interfaces, and guide the design of new social environments and interfaces. A broader theory of social presence can guide more ...

It has long been a challenge for online game providers that, after playing a game for a certain period of time, online game players frequently switch to alternative games without much hesitation. Current IS continuance theories, that are mainly developed to interpret user continuance of general utilitarian IS, are ineffective to interpret user continuance of hedonic IS. In this study, based on ...

Video instant messaging tools are not as widely used as we would have predicted and have so far failed to fulfill their promise to become an indispensable tool of social presence, interacting within the workgroup environment and creating a sense of community. Whilst users are becoming comfortable with videoconferencing and software video meetings, the use of video in “awareness” is still very u...

By default, presence delivered using the presence event package for the Session Initiation Protocol (SIP) is represented in the Presence Information Data Format (PIDF). A PIDF document contains a set of elements, each representing a different aspect of the presence being reported. When any subset of the elements change, even just a single element, a new document containing the full set of eleme...

In this paper I shall present a treatment of lexical and grammatical tone and vowel length in Hausa, as implemented in an emerging bidirectional HPSG of the language based on the Lingo Grammar Matrix (Bender et al., 2002). I shall argue in particular that a systematic treatment of suprasegmental phonology is indispensible in an implemented grammar of the language, both for theoretical and pract...

In this paper an estimator for speech enhancement based on Laplacian Mixture Model has been proposed. The proposed method, estimates the complex DFT coefficients of clean speech from noisy speech using the MMSE  estimator, when the clean speech DFT coefficients are supposed mixture of Laplacians and the DFT coefficients of  noise are assumed zero-mean Gaussian distribution. Furthermore, the MMS...

The Geopriv Location Object introduced by the Presence Information Data Format-Location Object (PIDF-LO), RFC 4119, defines a basic XML format for carrying geographical information of a presentity. This document defines PIDF-LO extensions to convey information about moving objects. Elements are defined that enable expression of spatial orientation, speed, and heading of the presentity. Informat...

Our present paper will invert the discussion, as it were, and ask a different question. What bearing does the change in the content of social thought have on religious understanding? We will argue that it has had a profound impact both on the scientific study of religion and on the believer's appropriation of the faith. It is not surprising that theory development would impact upon the scientif...
