Is there a positive counterpart to negligence? In the philosophical literature, there is a widespread asymmetry assumption according to which agents can be blameworthy for unwitting wrongdoing (negligence) but not praiseworthy for unwitting rightdoing. This project empirically ex...

Hedgehog reconstruction of polygons: Non-central sections and slabs

Abstract We show that a polygon can be uniquely determined by the lengths of non-central sections supporting a piecewise-analytic hedgehog in the interior of the polygon. We also prove the analogous result for slab areas: an origin-symmetric polygon can be reconstructed from the...

Catalan Bounds for Symmetric Strength‐Two Orthogonal Arrays

ABSTRACT A Hamming shell construction is a two‐level array obtained by taking every binary vector of a given Hamming weight a prescribed number of times, for each weight in turn. Such arrays are invariant under all permutations of the factors, and they are strength‐two orthogonal...
