The application of knowledge engineering techniques to expert and consultative systems has tended to out-run the development of a conceptual basis for such applications. This paper presents some conceptual analysis, within the domain of knowledge engineering, of expertise, rule-following and, in particular, of competence, which is perhaps the crucial concept in the area. Examples are given from...

Definitions Also referred to as crib or cot death, SIDS has been defined by the National Institutes of Health Consensus Development Conference on Infantile Apnea and Home Monitoring as “the sudden death of an infant or young child, which is unexplained by history and in which a thorough postmortem evaluation fails to demonstrate an adequate cause of death.” A thorough postmortem evaluation incl...

OBJECTIVES To evaluate and compare birthweight and scores as predictors of neonatal mortality in a Neonatal Intensive Care Unit (NICU). METHODS The survey included 494 newborns admitted to the neonatal intensive care unit (NICU) of a general hospital in Porto Alegre, southern Brazil, immediately after delivery, between March 1997 and June 1998.

We evaluated a comprehensive hospital-based infant safe sleep education program on parental education and safe sleep behaviors in the home using a cross-sectional survey of new parents at hospital discharge (HD) and 4-month follow-up (F/U). Knowledge and practices of infant safe sleep were compared to the National Infant Sleep Position Study benchmark. There were 1092 HD and 490 F/U surveys. Su...

We have identified a new Dictyostelium p21-activated protein kinase, PAKc, that we demonstrate to be required for proper chemotaxis. PAKc contains a Rac-GTPase binding (CRIB) and autoinhibitory domain, a PAK-related kinase domain, an N-terminal phosphatidylinositol binding domain, and a C-terminal extension related to the Gbetagamma binding domain of Saccharomyces cerevisiae Ste20, the latter t...
