Lecture Notes in Computer Science- P5:This year, we received about 170 submissions to ICWL 2008. There were a total of 52 full papers, representing an acceptance rate of about 30%, plus one invited paper accepted for inclusion in this LNCS proceedings. The authors of these accepted papers came from many different countries. | 10 . Liao and . Lu research in online learning 21 and online shopping 20 revealed that perceived ease of use was not a good predictor of intention to use. Further research on the application of TAM in different environments is necessary. The Perceived Characteristics of Innovating PCI Constructs Rogers 27 identified attributes of innovation that are fundamental to acceptance behavior including relative advantage complexity compatibility trialability and observability. Based on the work of Rogers and others Moore and Benbasat 23 expanded the innovation characteristics into seven constructs and developed an instrument to measure the perceptions. These constructs are relative advantage ease of use compatibility image result demonstrability visibility and trialability. The first PCI construct namely relative advantage presents the degree to which a potential adopter considers the innovation as providing an advantage over previous ways of performing the same task. The second construct ease of use is similar to Rogers concept of complexity 27 and captures the extent to which a potential adopter considers the use of the target system to be free of effort 13 . Moore and Benbasat s construct of compatibility is consistent with that of Rogers the level to which an innovation is perceived as being consistent with the existing values needs and past experiences of potential adopters. 23 . Moore and Benbasat 23 indicated that the image construct which is a part of relative advantage in Rogers framework can independently predict innovation use. The image construct denotes the perception when using an innovation in terms of improving the social status of the potential adopter. Furthermore Rogers attribute of observability is divided into two constructs of result demonstrability and visibility defined respectively as the tangibility of the results of using an innovation and the extent to which potential adopters see the innovation as being visible in the adoption .
