So far, research in computer-mediated collaboration has investigated various factors influencing the amount of social presence experienced in online settings. This experimental study broadens the perspective and investigates social presence as a causing factor on participants’ perception on task, medium and collaboration. Therefore an experiment with between subject design was conducted, with m...

Research on virtual learning groups is still in its infancy, despite the related technology’s proliferation in education institutions. This paper reports on an experiment investigating the relationships among type of technology, gender, social presence, and learning outcomes. Using a 2x2 factorial design, each same-gender group collaborated on a learning task, using either videoconferencing, or...

Social Presence is the concept of ‘being there’, of emotional connectedness to another person. As relationships are increasingly formed by spatially disparate partners, supporting social presence has become more important. As many intimate acts involve touching, this paper investigates the impact that heat, one aspect of touch, has upon social presence. This is presented in the form of a therma...

This paper addresses the multi-mode multi-skilled resource-constrained project scheduling problem. Activities of real world projects often require more than one skill to be accomplished. Besides, in many real-world situations, the resources are multi-skilled workforces. In presence of multi-skilled resources, it is required to determine the combination of workforces assigned to each activity. H...

With the growing popularity of information and communication technologies (ICT), researchers from information systems (IS) field are increasingly interested in the factors influencing user satisfaction in computer-mediated environment. Drawing on media synchronicity theory (MST), this study explores how various media characteristics influence user satisfaction through social presence. The resul...

An efficient and environmental-friendly synthetic route to 1,8-dioxodecahydroacridines derivatives have been developed via multi-component one-pot Hantzsch reaction of various aldehydes and ammonium acetate with 2 equivalents dimedone in the presence of Phosphorus pentoxide supported on aluminaas catalyst under solvent-free conditions. The present approach offersseveral advantages such as short...
