Abstract
A simple theory for material culture change
Robert Laxton
C D Litton
3 - 10
A formal model of type change within a class of artefacts is constructed which, it is hoped, will describe such processes in many archaeological situations. The theory predicts the familiar sigmoidal curve for the rise in popularity of an artefactual type at the expense of other types fulfilling the same function. The examples used all come from one report, the 1951 survey of the Mississippi Alluvial Valley, so that comparisons of various kinds can be made. Au(abr)
An algorithm for fitting circles and ellipses to megalithic stone rings
Ian O Angell
John W Barber
11 - 16
The authors, who represent the 'rope and pegs' side in the debate on the mathematical sophistication required for constructing megalithic rings, offer a simple objective algorithm for obtaining ellipse and circle fits for any given site, which may then be used in a statistical study of site metrology. Further, the dangers of accepting a fit composed of a number of circular arcs for a particular site are demonstrated by comparing Thom's results for Avebury with those produced by the new method.

The drawing of archaeological sections and plans by computer
J M Duncan
Peter L Main
17 - 26
Describes an experimental package of computer routines (GRASP) for the drawing of archaeological sections and plans, in a form suitable for publication, from the pencil sketches made on site. The final effect is developed interactively on a graphical display; a variety of conventions, stippling densities, fade-off borders between layers etc is available, and text can be positioned on the drawing as required. The finished drawing is then plotted by digital plotter. Au(abr)
Archaeological context sorting by computer
Edward C Harris
27 - 29
Draws attention to some ambiguities in the report on the computer analysis of the Bishophill (York) sequence, and suggests a revised sequence diagram.
