  We prove two ZFC theorems about cardinal invariants above the continuum which
are in sharp contrast to well-known facts about these same invariants at the
continuum. It is shown that for an uncountable regular cardinal $\kappa$,
$\mathfrak{b}(\kappa) = {\kappa}^{+}$ implies $\mathfrak{a}(\kappa) =
{\kappa}^{+}$. This improves an earlier result of Blass, Hyttinen, and Zhang.
It is also shown that if $\kappa \geq {\beth}_{\omega}$ is an uncountable
regular cardinal, then $\mathfrak{d}(\kappa) \leq \mathfrak{r}(\kappa)$. This
result partially dualizes an earlier theorem of the authors.
