Thank you Melinda!

I figured since I had my name on the article, that was already enough for

And thank you too for suggesting uploading a web version. Reading the T&F
page you found, it looks like I can post a preprint version and so I put a
copy here <>. Despite
subsequent revisions, it is still quite close to the published version.
