The Unitary Association Method of Relative Dating and Its Application to Archaeological Data

The primary objective of relative dating techniques is to determine a reliable sequence of archaeological deposits. This task becomes more difficult whenever our research steps beyond individual sites to the study of intercommunity relationships because we need to develop some means of associating unconnected deposits in time. Radiocarbon dating, as a stand-alone method, cannot always be used to draw reliable correlations between sites. The relevance of archaeological dates, including absolute dates, relies ultimately on the determination of artifact or sample associations and their respective superpositional relationships. The Unitary Association Method of Relative Dating is an alternative to seriation methods that is less susceptible to spatial variation and offers analytical strengths needed for regional chronological analyses.     

A time and place for everything: an essay on recreation, re-Creation and the Victorians

The institution of more regulated and spatially distinctive work practices from the early-eighteenth century onwards, together with the later Victorian penchant for classification, “cost-benefit analysis” and social theorizing drew increasing attention to the nature and use of leisure time amongst the ordinary mass of people. Mid-nineteenth century theorems began to advocate causal connections between the perceived inactivity of most leisure forms and the moral decline of the working class, and adherents to such theorems sought thereafter to institute new and improving means of recreation, or more extremely, re-Creation as a cure for the Nation's ills. Drawing further strength from constructed contrasts between the precepts of an earlier aristocratic and leisured eighteenth century, the Victorian “recreationists” sought both temporal means (based upon the use of Sunday particularly) and spatial strategies (from the design of the home, through to the set-aside space of the seaside resort) to instil discipline into leisure and to marginalize certain forms of unacceptable behaviour.     

THE LONG-RUN ECONOMIC IMPACTS OF FEDERAL,STATE, AND LOCAL FISCAL POLICIES IN METROPOLITAN AREAS*

ABSTRACT. This paper uses new estimates of metropolitan factor demand and output supply functions to study how federal, state, and local fiscal policies affect metropolitan economies. We illustrate our work with findings for ten metropolitan areas in five states for changes in state corporate income taxes, local property taxes, the federal corporate income tax, an investment tax credit, interest rates, public capital stocks, output prices, and tax and regulatory policies affecting gross wages. It is clear from these simulations that a policy that is nominally the same everywhere will have repercussions that vary widely across regions and cities.     

AN ASSESSMENT OF BACK-SCATTERED ELECTRON PETROGRAPHY AS A METHOD FOR DISTINGUISHING MEDITERRANEAN OBSIDIANS

The recent application by Burton and Krinsley (1987) of back-scattered electron (BSE) petrography to obsidians from sources located in the south-western United States established that this method can effectively resolve and characterize included micro-crystalline phases that have proven difficult to analyse by optical thin-section microscopy. In the first extension of their original study, we have examined, using BSE petrography, obsidians from island sources located in the Mediterranean, including sources known to have been exploited in prehistory. Because of the kinetic contrasts on their crystallization, these microcrystalline phases reflect the magmatic history of the obsidian, providing information about superheating, supercooling, sub-solidus processes, and other phenomena. This information is of significance for the chemical analysis of Mediterranean obsidians and also as the basis for a powerful alternative to existing non-destructive analytical methods for the sourcing of archaeological and art-historical obsidian.     

MULTICOIN: A TOOL FOR CLASSIFYING COINS IN A MULTIMEDIA ENVIRONMENT

Classifying coins found during excavation is a challenging task for the archaeologist. This paper describes a multimedia system designed to assist the archaeologist by enabling him either to classify coins based on a pre-existing catalogue or to draw up his own catalogue for specific purposes. The system can also be used to train novices in the field: following an initial screening, the archaeologist only has to examine coins specifically requiring his expertise. A case study uses coins minted in Salerno 800–1200 AD, but the system has been designed to classify any set of coins by simply changing the underlying knowledge base. Very little training is required to operate the user-friendly system, which runs on multimedia PCs, as it is written using the C++ language and makes full use of the advanced features of Windows 3.11.
