You can get copies of my publications in several ways:
On Web of Science use the search term "au=stewart n and (ad=warwick or
au=wills aj)" or my Researcher ID (A-1555-2010)
I have a Google Scholar account
The DOI links after each paper should take you directly to the
publisher's web page where you can download the PDF, providing you have a
subscription.
Check the boxes after the papers and fill in your e-mail at the bottom
of the page and I will e-mail the papers to you immediately. This is useful
if you do not have a subscription to the journal.
