+
+ \larger \larger Prior work by the authors showed that randomly given
+ barnstars to very active editors (top 1\% in a month) resulted in
+ more edits and a positive feedback loop in English Wikipedia.
+
+ \begin{itemize}
+ \larger \larger
+ \item Like before, gives barnstars to \e{randomly} selected users --
+ but this time to editors of varying activity level (e.g.,
+ 91-95$^{\mathrm{th}}$, 96-99$^{\mathrm{th}}$, and 100$^{th}$
+ percentile of editing in the month). Plus a ``control'' group of
+ other editors who do not receive the award.
+ \item Follow post-award activity on Wikipedia.
