Query: A Kochen-Specker Theorem for Unsharp Spin 1 Observables   Unsharp spin observables are shown to arise from the fact that a residual
uncertainty about the actual alignment of the measurement device remains. If
the uncertainty is below a certain level, and if the distribution misalignments
is covariant under rotations, a Kochen-Specker theorem for the unsharp spin
observables follows: There are finite sets of directions such that not all the
unsharp spin observables in these directions can consistently be assigned
approximate truth-values in a non-contextual way.
