Cut-off Sampling Design: Take all, Take Some, and Take None

Extended Abstract. Sampling is the process of selecting units (e.g., people, organizations) from a population of interest so that by studying the sample we may fairly generalize our results back to the population from which they were chosen. To draw a sample from the underlying population, a variety of sampling methods can be employed, individually or in combination. Cut-off sampling is a pr...

Visiting Some Relatives of Peirce's

The notion of a relational grammar is extended to ternary relations and illustrated by a fragment of English. Some of Peirce's terms for ternary relations are shown to be incorrect and corrected. Binary relations have been studied extensively by Peirce and Schrr oder in the nineteenth century, and in this century by Tarski and his students. No comparable attention has been paid to ternary relat...

Skeletons of Some Relatives of the N-cube Skeletons of Some Relatives of the N-cube

We study the skeleton of several polytopes related to the n-cube, the halved n-cube, and the folded n-cube. In particular, the Gale polytope of the n-cube, its dual and the duals of the halved n-cube and the complete bipartite sub-graphs polytope.

Applying the metaphor in Warner’s editorial, we could say that in Canada older anesthesiologists are “in the driver’s seat,” whereas in the United States, they usually are “backseat drivers” – involved in the crucial parts of the anesthetic but otherwise leaving patient care to the individual actually “behind the wheel....
