The social program Habitat was created to overcome the challenges presented in the marginalized urban areas in Mexico due to high concentrations of poverty. This paper presents the results of an impact evaluation of the effects of Habitat on basic infrastructure during the first two years

to form networked virtual supercomputers or metacomputers. While the physical infrastructure to build such systems is becoming widespread, the heterogeneous and dynamic nature of the metacomputing environment poses new challenges for developers of system software, parallel tools, and applications

This article examines the fundamental

This pattern language describes the building blocks of typical distributed object frameworks, such as Java RMI, CORBA,.NET Remoting, web object systems, or web services. The patterns cover the basic infrastructure manner, as it can be observed by developers using a distributed object systems

) workflow automation to generate workflow implementations from workflow specifications. This paper provides a high-level overview of the current workflow management methodologies and software products. In addition, we discuss the infrastructure technologies that can address the limitations of current

This paper presents Scribe, a scalable application-level multicast infrastructure. Scribe supports large numbers of groups, with a potentially large number of members per group. Scribe is built on top of Pastry, a generic peer-to-peer object location and routing substrate overlayed on the Internet

This paper gives the main definitions relating to dependability, a generic concept including as special case such attributes as reliability, availability, safety, integrity, maintainability, etc. Security brings in concerns for confidentiality, in addition to availability and integrity. Basic

The material presented in this appendix summarizes and documents the information collected from 29 basic infrastructure programs administered by the Washington state departments of Community, Trade and Economic Development (CTED), Ecology (DOE), and Health (DOH) that are the focus

Indirection Infrastructure (i3) that offers a rendezvous-based communication abstraction. Instead of explicitly sending a packet to a destination, each packet is associated with an identifier; this identifier is then used by the receiver to obtain delivery of the packet. This level of indirection decouples

residual across countries. At a deeper level, we document that the differences in capital accumulation, productivity, and therefore output per worker are driven by differences in institutions and government policies, which we call social infrastructure. We treat social infrastructure as endogenous
