Research into the effectiveness of online learning has yielded a number of potential models of online learning effectiveness but no verified theoretical frameworks (Garrison & Arbaugh, 2007). Extensive literature exists related to the Community of Inquiry (CoI) model, first proposed by Garrison, Anderson and Archer (2000) to describe the components of an ideal educational experience. The model ...

E-commerce diffusion has apparently taken different paths in different nations partially because of the implications of national technology and the political and economic environments. This paper examines both the diffusion and the impacts of e-commerce in China, based on results of a large-scale survey conducted in 10 countries including China. Findings lead to the conclusion that Chinese firm...

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...

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...

background and aims: several drugs are being used in treatment of hsv infection in human but still introducing an effective safe drug is desirable. methods: we investigated the inhibitory effect of morphine on replication of hsv in vitro. results: the results indicated that a concentration of up to 200 ug/ml morphine had a limited effect on vero cell viability. at this concentration the growth ...

Background and Aims: Several drugs are being used in treatment of HSV infection in human but still introducing an effective safe drug is desirable. Methods: We investigated the inhibitory effect of morphine on replication of HSV in vitro. Results: The results indicated that a concentration of up to 200 ug/ml morphine had a limited effect on Vero cell viability. At this concentration the growt...
