I cannot get the link to work and would be very much interested in reading the article. Perhaps it is only busy, but would you mind checking the link anyway?

You might use GOOGLE with "pier luigi luisi" as a search phrase. This should turn up references or even publically available papers. (Maybe GOOGLE SCHOHLAR would be useful.)
