Pilot data indicate psychiatry residents use online resources daily for their education in various settings. Resident perceptions of individual website's trustworthiness, ease of use, and sources of clinical decision-making and personal learning suggest potential opportunities for educators to better understand the current use of these resources in residency training. Reported barriers including lack of faculty guidance suggest opportunities for academic psychiatry. Further study is necessary at multiple sites before such results may be generalized.
This paper describes the design and implementation of SecondSite, a cloud-based service for disaster tolerance. SecondSite extends the Remus virtualization-based high availability system by allowing groups of virtual machines to be replicated across data centers over wide-area Internet links. The goal of the system is to commodify the property of availability, exposing it as a simple tick box when configuring a new virtual machine. To achieve this in the wide area, we have had to tackle the related issues of replication traffic bandwidth, reliable failure detection across geographic regions and traffic redirection over a wide-area network without compromising on transparency and consistency.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
