Academic culture

For this module (2) I'm going to focus on the current theory around cost/ benefit analysis of implementing e-leanring into HE. The research will focus on the cultural differences within academic departments and how this may effect the design of any cost benefit evaluation. A number of questions:

Even if you can develop a more meaniful representation of the costs and benefits for e-learning within a given academic context, will other cultural and social factors etc. still limit the uptake?

How does this research idea relate to general change management strategies?

Is academic culture that well researched to make this research valid?

Are there any philosophical or epistomological objections to using a cost benefit approach in the literature - is the term itself difficult in some academic contexts?
