USGS Materials Maps
Visitors can learn about the relatively new field of imaging spectroscopy, which allows specific absorption features, caused by chemical bonds in materials, to be mapped spatially. Topics include an introduction to the procedure, environmental applications, vegetation and biota mapping, lithologic, and mineral mapping. A set of links provides access to reports, accompanied by spectroscopic images, on the use of this new tool in chosen locations.

The Eighth H.W. Arndt Memorial Lecture: Rehabilitating the Unloved Dollar Standard
The international dollar standard is an accident of history that greatly facilitates international trade and exchange. But erratic U.S. monetary and financial policies, have upset the U.S. and a world economy thus makes foreigners unhappy. Paradoxically, the asymmetrical nature of the dollar standard also makes many Americans unhappy because they cannot control their own exchange rate. Although nobody loves the dollar standard, it is a remarkably robust institution that is too valuable to lose a

Quelles machines pour enseigner la langue ?
This paper first presents a history of Computer-Assisted Learning (CAL), setting its origins in the 1920s with the invention of mechanical learning machines. The use of the computer then allowed the development of different types of language learning activities: comprehension tasks, simulations, etc. However, without the contribution of natural language processing (NLP), these activities are of limited use. We address the problem of the integration of NLP in CALL systems while summing up the cha
