Adoption of Instant Messaging

Su, Po-fang 20 August 2004 (has links)
Nowadays, the internet is an unseperatable part of human life and instant messaging software becomes an important role of communication channel. There are 40 million global IM registration popularity who use IM and billions of messages are sent everyday. In Taiwan, there are 6.5 million registration popularity and IM is the third important internet appilication, besides WWW and e-mail. As IM has become more and more important, there was few academic researchs published. We investigated consumer IM adoption behavior by focus group interview and structural equation model analysis. After holding a focus group interview, some antecedent of adopting IM was found out. Then we integrated technology acceptance model with media richness, computer self-efficacy and subjective norm as the antecedents of perceived usefulness(PU) and perceived ease of use(PEU) and analysised this structural equation model with LISREL. We found that subjective norm is an antecedent of PU, media richness and computer self-efficacy are PEU¡¦s antecedents. Finally, we made some suggestion for practice and other researchers base on the result.

Kutlay, Aysegul 01 February 2012 (has links) (PDF)
In this study, the factors affecting the acceptance of mobile homecare system were examined. These factors were assessed by taking Unified Theory of Acceptance and Use of Technology (UTAUT) as a theoretical model. The main feature of this thesis (differing from the other studies in the literature) is that the user acceptance study model is analyzed on a system that is not realized yet. So, this study has two dfferent perspectives. The first one is the examination the results of UTAUT for a system in the design phase. The other one is the investigation of the relations of factors that affect the acceptance of mobile homecare by patients with chronic diseases. For these purposes, a homecare system model was formulated based on similar studies in the literature. A quantitative research was conducted on this formulated system. The results were evaluated by Structural Equation Model. According to the results of structural model, all hypotheses were supported and consistent with the earlier study results, which were based on completed and in-use systems. Therefore, this study shows that, for systems in the design level, the acceptance models can also be applicable and may give similar results. The results also show that performance expectance was the most significant predictor for patients
