For any poset P let J(P) denote the complete lattice of order ideals in P. J(P) is a contravariant functor in P. Any order-reversing map f: P-+Q can be regarded as an isotone (= order-preserving) map of either P\* into Q or P into Q\*. The induced map of J(Q) to J(P\*) (resp. J(Q\*) into J(P)) will

## Note on the Homotopy Type of Mapping Cones" PETER HILTON I n [2] and [3] we proved certain theorems about the semi-group of homotopy types of based spaces where the composition operation is just the disjoint union with identification of base points. These results were suggested by certain obse
This paper examines the sorting of residents between for-profit and nonprofit nursing homes and the health outcomes of those residents conditional on ownership type. Using data from the 1987 National Medical Expenditure Survey, we find evidence of systematic sorting of residents by ownership type, a
