  It is well known that an ordered normed vector space $X$ with normal cone
$X_+$ has an order-preserving norm that is equivalent to the original norm.
Such an equivalent order-preserving norm is given by \begin{equation} \sharp x
\sharp = \max \{ d(x, X_+), d(x, - X_+)\}, \qquad x \in X. \end{equation} This
paper explores the properties of this norm and of the half-norm $\psi(x) =
d(x,-X_+)$ independently of whether or not the cone is normal. We use $\psi$ to
derive comparison principles for the solutions of abstract integral equations,
derive conditions for point-dissipativity of nonlinear positive maps, compare
Collatz-Wielandt numbers, bounds, and order spectral radii for bounded
homogeneous maps and give conditions for a local upper Collatz-Wielandt radius
to have a lower positive eigenvector.
