The concept of presence, i.e. the sensation of ‘being there’ in a mediated environment, has received substantial attention from the virtual reality community, and is becoming increasingly relevant both to broadcasters and display developers. Although research into presence is still at an early stage of development, there is a consensus that presence has multiple determinants. To identify and te...

In its quest for knowledge and understanding the Information Systems (IS) field has generally been torn between positivist and interpretivist approaches. However, in this paper an approach that accepts many of the underlying beliefs of both positivism and interpretivism is presented: the fictive approach. This blended approach – most comprehensively developed by Vaihinger reveals how much of wh...

Design science is an established approach in IS research and the literature provides us with a fruitful discussion on its basic concepts, for instance, the IS research cycle (Hevner, March, Park and Sudha 2004), IT artifacts (Orlikowski and Iacono 2001; Weber 2003), or design theories (Markus, Majchrzak and Gasser 2002; Walls, Widmeyer and El Sawy 1992). However, many authors advocating the sta...

Critical realism is emerging as a viable philosophical paradigm for conducting social science research, and has been proposed as an alternative to the more prevalent paradigms of positivism and interpretivism. Few papers, however, have offered clear guidance for applying this philosophy to actual research methodologies. Under critical realism, a causal explanation for a given phenomenon is infe...

Information and Communications Technologies (ICT) penetration is growing at exponential rates and affecting societies, countries and organizations, which has led to a need for understanding whether they contribute to development. To ascertain whether ICT are contributing to development, the example of a current ICT, Twitter is used, along with the aim of this research: To understand and explain...

This paper presents a conceptual model to allow communities self-detecting fake and inappropriate news on social network sites based on collective intelligence and inspired by Viable Systems Approach. The model is grounded on an extension of the Gruber model (on which Collective Knowlegde Systems are based) which incorporates a Consensus Method typically used in the Group Decision Making.

Egocentered networks are common in social science research. Here, the unit of analysis is a respondent (ego) together with his/her personal network (alters). Usually, several variables are measured to describe the relationship between egos and alters. In this paper, the aim is to estimate the reliability and validity of the averages of these measures by the multitrait-multimethod (MTMM) approac...
