Declarative networking is an approach where distributed computations are modeled and programmed using declarative formalisms based on extensions of Datalog. On a logical level, programs (queries) are specified over a global schema and are computed by multiple distributed computing nodes over which the input database is partitioned. These nodes can perform local computations and communicate asyn...

Cost-effectiveness analysis (CEA) offers decision makers a structured, rational approach with which to improve the return on resources expended. But decades after its widespread promotion to the medical community, policy makers in the United States remain reluctant to use the approach formally. Indeed, the resistance to economic evidence in the United States in an era of evidence-based medicine...

Modern clinical practice relies on evidence-based medicine (EBM) and evidence-based guidelines (EBGs). The critical evaluation of EBGs value is therefore an essential step to further improve clinical practice. In our opinion, correlating levels of evidence and grades of recommendation can be an easy tool to quickly display internal consistence of EBGs.
