Southeastern data inconsistent with Paleoindian demographic reconstruction

Southeastern data inconsistent with Paleoindian demographic reconstruction.

Buchanan et al.’s (1) statistical evaluation of radiocarbon dates as a demographic proxy depends on accurate and complete datasets. However, their database is incomplete for the Southeast, where 181 radiocarbon dates from Paleoindian and Early Archaic deposits are now available (2). Only a fraction of these are included in their analysis. Within the more complete dataset only 4 of these determi...

Repairing Inconsistent XML Data with Functional Dependencies

The World Wide Web is of strategic importance as a global repository for information and a means of communicating and sharing knowledge. Its explosive growth has caused deep changes in all the aspects of human life, has been a driving force for the development of modern applications (e.g., Web portals, digital libraries, wrapper generators, etc.), and has greatly simplified the access to existi...

Logical Bilattices and Inconsistent Data

The notion of a bilattice was rst proposed by Ginsberg as a general framework for many applications. This notion was further investigated and applied for various goals by Fitting. In the present paper we develop proof systems, which correspond to bilattices in an essential way. We then show how to use those bilattices for ef-cient inferences from possibly inconsistent data. For this we incorpor...
