In four studies, recognition memory for faces rated as similar to a prototype was found to be inferior to memory for faces rated as unusual in appearance. This result was obtained under both incidental and intentional learning conditions, at presentation rates ranging from 3 to 15 sec, and with retention intervals from 3 to 24 hr. A fifth experimentâ€¦ (More)

We give a homotopy theoretic characterization of stacks on a site C as the homotopy sheaves of groupoids on C. We use this characterization to construct a model category in which stacks are the fibrant objects. We compare different definitions of stacks and show that they lead to Quillen equivalent model categories. In addition, we show that these modelâ€¦ (More)

We give a homotopy theoretic characterization of sheaves on a stack and, more generally, a presheaf of groupoids on an arbitary small site C. We use this to prove homotopy invariance and generalized descent statements for categories of sheaves and quasi-coherent sheaves. As a corollary we obtain an alternate proof of a generalized change of rings theorem ofâ€¦ (More)

We extend the notion of algebraic stack to an arbitrary subcanonical site C. If the topology on C is local on the target and satisfies descent for morphisms, we show that algebraic stacks are precisely those which are weakly equivalent to representable presheaves of groupoids whose domain map is a cover. This leads naturally to a definition of algebraicâ€¦ (More)

The purpose of this paper is to give a new presentation of some of the main results concerning Landweber exactness in the context of the homotopy theory of stacks. We present two new criteria for Landweber exactness over a flat Hopf algebroid. The first criterion is used to classify stacks arising from Landweber exact maps of rings. Using as extra inputâ€¦ (More)

Let I be a small indexing category, G : I â†’ Cat be a functor and BG âˆˆ Cat denote the Grothendieck construction on G. We define and study Quillen pairs between the category of diagrams of simplicial sets (resp. categories) indexed on BG and the category of I-diagrams over N(G) (resp. G). As an application we obtain a Quillen equivalence between theâ€¦ (More)

Part One of this series described how an Operations Improvement process, computer simulation, and a focus on the dollars per patient day or unit of service ($PPD) can enhance a hospital's cost-reduction efforts. Part Two will address the organizational culture issues that can hamper or support nursing's cost-reduction efforts.

By creating and promoting an "intrapreneurial climate" with appropriate "actions" within the department of nursing, nurses may exploit their creativity and commitment to health care without leaving the organization. This article discusses an approach to fostering nurse intrapreneurship and gives examples of success achieved at Stanford University Hospital.
