  Let $UC(K)$ denote the Banach space of all bounded uniformly continuous
functions on a hypergroup $K$. The main results of this article concern on the
$\alpha$-amenability of $UC(K)$ and quotients and products of hypergroups. It
is also shown that a Sturm-Liouville hypergroup with a positive index is
$\alpha$-amenable if and only if $\alpha=1$.
