Archaeologists, along with other Quaternary researchers, seldom rely upon a single radiocarbon determination to provide an estimate of the age of the phenomenon which is the object of their study. There is an evident need for an explicitly formulated procedure for comparing sets of radiocarbon determinations from the same and from adjacent strata or sites, and for combining these where statistical and archaeological criteria indicate that this combination is warranted. The present contribution provides explicit modelling for a series of recommended procedures, a critique of previous methods, and paradigms for application of the recommended procedures.  相似文献

It has been said that serving on the U.S. Supreme Court is like being a member of an exclusive club. Yet within this club, there are even more exclusive clubs that only a small number of Justices are permitted to join. These shadowy associations are unseen by the public, receive no publicity, and are not even known to the Justices who are excluded. The existence of these secretive organizations has recently been revealed through the release of Justice Harry Blackmun's papers at the Library of Congress. This article is the first serious attempt to research the existence, membership, and practices of these clandestine alliances. Ultimately, as with many High Court practices, these newly uncovered connections may be in need of reform, and I offer a number of solutions to define membership criteria and improve their functioning.  相似文献

This paper argues the importance of the contribution that multivariate statistical techniques can make to the analysis of data from trace element characterization of sources of raw material and of artefacts. A threephase analysis is outlined: for the delimitation of sources of the raw material; the representation of the interrelationships of these sources; and the systematic and explicit allocation of artefactual material within the available universe of source groups. A model is developed using obsidian from New Zealand sources and presented as an example of the method.  相似文献

Theoderic the Great has long been considered a supremely able ruler whose reign ushered in a period of unprecedented peace and prosperity to the Italian peninsula. A common explanation for this was his ability to provide justice swiftly and equitably by means of a highly Romanized judiciary. But as in the later empire, corruption and venality posed serious challenges, as did problems associated with the limitations of a pre‐modern government. While Theoderic attempted to remedy these structural weaknesses through the creation of new offices, the available evidence challenges long‐held assumptions as to just how successful he was in this regard.  相似文献

This paper describes the discovery of the first open‐air Upper Palaeolithic site to be found in Scotland, at Howburn, near Biggar in South Lanarkshire. An account is given of the composition and distribution of the lithic assemblage, which is discussed in terms of its British and north‐west European context. Provisional parallels drawn are with the Late Hamburgian (Havelte) sites and assemblages of southern Scandinavia, northern Germany and the Netherlands. There is no absolute dating evidence for the site, but an age in the region of 12,000 14C yr BP, towards the end of the earlier (Bølling) Lateglacial Interstadial stage, is proposed on the basis of the lithic artefacts.  相似文献
