Wardle

1.  Engagement, Imagination, and Alignment.
Engagement would be when Alan started his job and sent emails to the staff and faculty.
Imagination would be the way Alan saw himself as "GOD" when in reality he was just a tool for the staff and faculty.
Alignment would be what Alan did not do as far as trying to get along because of his imaged job title.  It would be hard to give up what you were taught lust to have someone else tell you that its wrong now do it this way or its the highway.

3.  Because he imagined himself as something he wasn't.  So in his mind everyone else was wrong and he was right.  Well when he was hired they should have explained his job title in more detail then maybe he wouldn't have had his "God" complex.

5.  I agree with Gee and Wardle both.  Because when he started his job he wasn't in the dominate discourse.  And Wardle because of his imagined position in the work place.
