Let V be a vector space of signature (p,q). We construct two families of algebraic curvature tensors which generate the space of algebraic curvature tensors on V. We use these families to show that there exist Jordan Osserman algebraic curvature tensors with arbitrary Jordan normal form.

We study the higher-order Jacobi operator in pseudo-Riemannian geometry. We exhibit a family of manifolds so that this operator has constant Jordan normal form on the Grassmannian of subspaces of signature (r, s) for certain values of (r, s). These pseudo-Riemannian manifolds are new and non-trivial examples of higher-order Osserman manifolds.
