Reproductive and growth data were obtained on 779 and 564 yearling beef heifers and bulls, respectively, that had sires with yearling scrotal circumference data at the San Juan Basin Research Center, Hesperus, CO. Partial regression coefficients of reproductive and growth traits on inbreeding (FXC) and age of the individual and adjusted scrotal circumference of sire (SCSI) were obtained. Growth...

The paper presents a calculus of recursively-scoped records: a two-level calculus with a traditional call-byname λ-calculus at a lower level and unordered collections of labeled λ-calculus terms at a higher level. Terms in records may reference each other, possibly in a mutually recursive manner, by means of labels. We define two relations: a rewriting relation that models program transformatio...

Expert systems have been developed around one expert part ly because the expert has been totally responsible for the soundness of the knowledge base. Without strong aids to help ensure soundness in building expert systems, we must rely on the soundness of the mature cohesiveness of a human expert. As knowledge bases grow this mature expertise will not be adequate. We propose a new method (for e...
