At a recent workshop, experts discussed the benefits, risks, and research priorities associated with using genetically manipulated insects in the control of vector-borne diseases.
Pyrethroid resistance is becoming widespread in Anopheles gambiae mosquitoes, coinciding with expanded use of insecticide-treated nets (ITNs) throughout Africa. To investigate whether nets in use are still protective, we conducted household trials in northern and southern Benin, where An. gambiae mosquitoes are susceptible and resistant, respectively, to… (More)
Long-lasting insecticidal bednets (LLINs) are one of the major ways to control malaria, and they are widely accepted worldwide by communities in areas affected by malaria. One LLIN costs about US$5 to manufacture and is effective for about 5 years. They have two kinds of protective effects—one for the people directly under the nets, and one for the… (More)

Canonical data modeling (CDM) is a method for reducing the total cost of integrating information systems. CDM enhances model-driven development (MDD) by making explicit situations in which data components are being reused (i.e., shared across systems). In this paper, we present cost models for data modeling and data integration, with and without CDM. We… (More)
1. Introduction The U.S. Government operates seven distinct radar networks providing weather and aircraft surveillance for public weather services, air traffic control, and homeland defense. A next-generation, multifunction phased array radar (MPAR) concept has been proposed that could provide enhanced weather and aircraft surveillance services with… (More)
304 Insecticide-treated nets (ITNs) have been shown to reduce the burden of malaria in African villages by providing personal protection and, if coverage of a community is comprehensive, by reducing the infective mosquito population. We do not accept the view that scaling-up this method should be by making villagers pay for nets and insecticide, with… (More)
