Centers for disease control and prevention lead guidelines: do pediatricians know them?

American Academy of Pediatrics (AAP) fellows responded to a questionnaire measuring knowledge of 1991 Centers for Disease Control and Prevention (CDC) guidelines. Generalists' scores on a knowledge scale were positively correlated with reporting CDC and AAP documents as knowledge sources, and negatively correlated with private practice, medical school as a knowledge source, and age. However, private practitioners who read AAP documents scored well.     

Server consolidation using performance modeling

Server consolidation is crucial to improving a corporation's bottom line by providing savings in hardware, software, maintenance, facility, and labor costs. In today's cost-cutting environment, consolidation efforts can provide significant savings in IT expenditures. Overall potential consolidation benefits include: lower total cost of ownership, improved service levels and availability, and reduced business risks, resulting from consistent business management and resiliency. To fully realize consolidation benefits, businesses must focus on the performance and service levels provided to users in addition to reducing unused capacity. We present a new way to analyze consolidation alternatives using performance modeling and stepwise refinement, a methodology for efficient and effective modeling.
