Description
The number of adjacencies of a permutation, zero appended. An adjacency is a descent of the form $(e+1,e)$ in the word corresponding to the permutation in one-line notation. This statistic, $\operatorname{adj_0}$, counts adjacencies in the word with a zero appended. $(\operatorname{adj_0}, \operatorname{des})$ and $(\operatorname{fix}, \operatorname{exc})$ are equidistributed, see [1].

Description
The number of fixed points of a parking function. If $(a_1,\dots,a_n)$ is a parking function, a fixed point is an index $i$ such that $a_i = i$. It can be shown [1] that the generating function for parking functions with respect to this statistic is $$ \frac{1}{(n+1)^2} \left((q+n)^{n+1} - (q-1)^{n+1}\right). $$
