## 10 Discussion  
Previous research on the same field has provided evidence of the effects that Trust has on Intention to use e-Government services [58] and Perceived Risk has on Continuance Intention for teachers in Greece [51]. Findings from the present study suggest that in the presence of both attitudinal variables (trust, perceived risk) and operational variables (compatibility, advantage, _etc._) it is the second set that has a significant effect on intention to use. In more detail: Compatibility, Relative advantage and Job relevance, along with Perceived usefulness and Perceived ease of use are the five factors that influence intention to use e-Government services. Trust, Perceived Risk, Image, Subjective norm and Output quality, although included in the model, do not significantly affect intention to use. Thus, perceived social forces or social influence processes _i.e._, subjective norm and image, and trust and perceived risk, are weak predictors of intention to use, compared to cognitive factors and intrinsic characteristics of innovation compatibility. In a previous work, the authors suggested that for an effective adoption of e-Government websites, state government agencies should communicate websites to citizens through widespread and attractive awareness campaigns. Emphasizing advantages of the websites and real benefits that users would gain will lead to higher levels of perceived usefulness which subsequently will lead to higher levels of intention to use e-Government websites [58]. On the other hand, it becomes more important to raise the issue of Trust. If the state wishes to promote the use of e-Government services, then it is in its best interests to alter Trust of the citizens in e-Government [58]. Considering this finding, policy makers could focus on raising teachers' Trust in the internet as a means of getting information and accomplishing transactions, for example, training teachers in IT and internet skill on a regular basis. The present paper modifies and enriches previous findings, but considers the importance of operational variables. The analysis suggests that in the presence of operational factors, it is the operational factors that influence intention to use e-Government websites, compared to trust and perceived risk. Practical implications and suggestions should not avoid enhancing trust of citizens on the one hand and diminishing their perception of risk using e-Government on the other. What the findings of this paper suggest is that along with emphasizing and augmenting social benefits of using e-Government services, a greater and primary effort should be made in providing efficient and effective e-Government practices. These could satisfy citizens and engage them to use e-Government services further. Raising trust and diminishing perceived risk are important steps, but providing results and efficient solutions to citizens through e-Government services is more important in raising their intentions to use them. If a campaign could give a solution aimed at enhancing the trust of citizens and diminishing their perception of risk, along with empowering a citizen's image, it would not have the expected results unless it provides practical implications regarding ease of use, recognition of relative advantage and especially usefulness. Users find e-Government systems useful when they relate to their intrinsic characteristics, their interest and their working settings. Users will use e-Government systems if they help them to work more efficiently and effectively. Two axes arise regarding usefulness of educational e-Government systems in Greece. The first concerns the provision of useful information that citizens want or the information that will help them to perform administrative transactions. More specifically, this information usually concerns the legislative framework and practical solutions, such as filling in and submitting an application or a form. The second axis concerns teachers training in modern and prevailing pedagogic, psychological teaching models.
