This paper presents a comprehensive framework for describing the diffusion of the Internet in a country. It incorporates insights gained from in-depth studies of about 25 countries undertaken since 1997. The framework characterizes diffusion using six dimensions, defining them in detail, and examines how the six dimensions relate to underlying bodies of(More)
The idea of a National Information Infrastructure (NII) is in the air. The Clinton ad? ministration feels the NII can "transform the lives of the ~ > ; American people" [5], and NII has made the covers of ; ~ v ~ j Time and Newsweek. 1 The NII is old hat to members of the computer science corn! munity.

Determination of an appropriate wheelchair cushion to optimize loading on buttock tissue is crucial to pressure ulcer prevention. Standardized test methods aim to simplify selection by helping clinicians and users identify a class or category of cushions that will meet the important medical need of adequate pressure distribution. The objective of this(More)
If the 1, be considered a market ph’enome“on, with sustained double-digit growth and no apparent end in sight to the upward spiral. Recent lnrernet numbers arc stunning. Between ,Janwry 199.1 and January 1994, the number of hosts grew from 1,~313,000 to 2,217,OOO; an impressive 69% increase j7]. Over 70 countries have full TCP/IP Internet connectivity, and(More)
Early experiences with Web-based groupware point to new collaboration opportunities within and between organizations. We report the results of a study of more than 100 organizations that have used Web-based groupware to understand better how they are using it and what advantages and disadvantages they have experienced. We then use these data to develop a(More)
Over the years, we covered the globe with cities then linked them with railroads, highways, telephone lines, power grids, canals, and so forth. We are now deploying the Internet, and several organizations and projects are tracking this global diffusion [4]. This column describes one such project, the MOSAIC Group (www.agsd.com/ mosaicgroup.html) study of(More)
Everyone knows the Internet is growing rapidly, but measuring that growth with a degree of precision is difficult. At first it was easy to follow network diffusion. The Arpanet Completion Report [2] contains maps, topology diagrams, and traffic and performance statistics beginning with a sparse 4-link map drawn in 1969 and running through 1975 when the(More)
T good news is that the Internet has grown like a weed, and many welcome it as a tool for productivity and enlightenment; the bad news is that it is almost unknown in developing nations (see Table 1). This column offers the hypothesis that computer networks can improve life in developing nations at a relatively low cost. Dimensions of Development(More)
Imagine a modern personal computer. It has a direct-manipulat ion, WYSIWYG user interface, and programs for drawing, painting, writing, and other tasks. It is connected to a LAN with email, database, print, and other services. The LAN may be connected to other LANs, forming an internet, and it may be connected to a wide-area network like the Internet. That(More)
