As Richard says, we do not have insitutional licences for these products.
You, of course, are free to buy and use them should you wish, and both are quite cheap.
If you want free alternatives you could try...
Storybook http://storybook.en.softonic.com/ instead of Scrivener (it doesn't come with a word processer but does facilitate organising and planning)
and VUE perhaps for concept mapping. http://vue.tufts.edu/
You might also want to look at this list of mind mapping softare.
