Hominin evolution took a remarkable pathway, as the foraging strategy extended to large mammalian prey already hunted by a guild of specialist carnivores. How was this possible for a moderately sized ape lacking the formidable anatomical adaptations of these competing 'professional hunters'? The long-standing answer that this was achieved through the elaboration of a new 'cognitive niche' relia...

In recent years there have been several successful examples of crowdbases systems, used for very different purposes and built on a variety of technological artefacts, some ad-hoc, some generic. We presume it is possible to give a precise characterisation of what we call crowd-based sociocognitive systemsand postulate that it is possible to formulate a framework to model and implement actual cro...

Information explosion has led to diminishing awareness: disciplines are becoming increasingly specialized; individuals and groups are becoming ever more insular. This paper considers how awareness can be enhanced via text-based knowledge discovery. Knowledge representation is motivated from a socio-cognitive perspective. Concepts are represented as vectors in a high dimensional semantic space a...

Institutional theory has proven to be a central analytical perspective for investigating the role of larger social and historical structures of Information System (IS) adaptation. However, it does not explicitly account for how organizational actors make sense of and enact IS in their local context. We address this limitation by showing how sensemaking theory can be combined with institutional ...

The radical utilization of collaborative learning processes in Three-Dimensional (3D) multi-user virtual worlds has been widely investigated. However, a study to delineate a comprehensive pedagogical model aimed at facilitating the same productive-argumentative knowledge practices is still lacking. This chapter presents the most reliable principles of contemporary socio-cognitive learning theor...

This paper is an invitation to carry out science and engineering for a class of socio-technical systems where individuals – who may be human or artificial entities – engage in purposeful collective interactions within a shared web-mediated social space. We put forward a characterisation of these systems and introduce some conceptual distinctions that may help to plot the work ahead. In particul...

this article analyses the effects of post-zionism in israeli ,society and state. by using the discoursive analysis in social theory, the author argues that discourses such as post-zionism are the results of socio-political and economic conditions (processes), but their evolution is basically the result of the mental and value activities of their proponent, rather than the socio-political proces...
