Excellent job Aarti.
I still maintain that alot of people are not clear on the different models and why one should be prefered over the other. I am one such person. James did a great job explaining the models at the NCUC outreach in Dublin for which I am deeply thankful.
However It might be useful by way of introduction and/or explanation to write a quick sentence about each model so that there can be context to your article.I'm sure readers will appreciate it. Otherwise some people may not appreciate your critical analysis of the current dilemma.
Keep up the great work.I'm looking forward to further articles.
Warm regards
