Underlying this approach is the notion that sustained personal contacts with members are necessary to generate the generalised reciprocity norms that mobilise workers in times of need an...

The purpose of this research is to develop a research model that examines the impact of mobile social capital on technology adoption through IT artifact Influence. To do so, we suggest that mobile networks of practice as social actors affect technology use through the userIT artifact interaction in which mobile social capital lies, thus differentiating it from social capital and bestowing uniqu...
