E-file adoption: A study of U.S. taxpayers’ intentions

The United States Congress has set ambitious goals for the diffusion of e-government initiatives. One of congress’ goals for the 2007 tax year was for 80% of tax and informational returns to be filed electronically (IRS., 2004). In 2008, 90 million Americans choose to e-file (IRS., 2009); however, Congress’ goal of 80% adoption has still fallen short. This paper integrates the Unified Theory of Acceptance and Use of Technology (UTAUT) model, online trust, perceived risk, and optimism bias into a comprehensive model of e-file adoption. To empirically test the model a survey is administered to 260 United States taxpayers. Structural equation modeling is used to evaluate relationships between these concepts and intention to use. Results indicate performance expectancy, social influence, facilitating conditions, and optimism bias all have a significant impact on e-file intention. Trust in the internet and trust in the e-file provider were shown to significantly influence perceived risk. Implications for practice and research are discussed.

E-government adoption: A cultural comparison

E-government diffusion is an international phenomenon. This study compares e-government adoption in the U.K. to adoption in the U.S. In particular, this study seeks to determine if the same factors are salient in both countries. Several studies have explored citizen acceptance of e-government services in the U.S. However, few studies have explored this phenomenon in the U.K. To identify the similarities and differences between the U.K. and the U.S. a survey is conducted in the U.K. and the findings are compared to the literature that investigates diffusion in the U.S. This study proposes a model of e-government adoption in the U.K. based on salient factors in the U.S. A survey is administered to 260 citizens in London to assess the importance of relative advantage, trust and the digital divide on intention to use e-government. The results of binary logistic regression indicate that there are cultural differences in e-government adoption in the U.K. and the U.S. The results indicate that of the prevailing adoption constructs, relative advantage and trust are pertinent in both the U.S. and the U.K., while ICT adoption barriers such as access and skill may vary by culture. Implications for research and practice are discussed.

Analysis and design on macro architecture of an on-demand E-government system

The existing E-government systems in China are always tight coupling, which are difficult to be replanted and adapted to the new EG business requirements. The paper schemes out an On-Demand architecture for E-government System. It discusses the process macro point of view. As for of the ＂On-Demand＂ design in macro Service On Demand （macro-SOD）, it applies the theoretical thoughts of SOA （Service Oriented Architecture）, that is ＂services oriented＂, into the encapsulation of system functional components. In the paper, we discuss the divisions and the main types of macro EG ser＇Aces. The new system works more efficiently with characters of loose coupling, reusable components, dynamic application integration, dynamic workflow modeling and etc. The researching fruits will benefit the application theories of information system＇s design and solve the problems of existing EG systems.
