The goodness of fit and statistical significance of seriation solutions

This paper presents a method for determining the statistical significance and goodness of fit of seriation solutions based on correspondence analysis. The basic assumption is that seriation solutions corresponding to relative chronological sequences should have unimodal distributions of types across assemblages in a sequence. In order to evaluate significance of chronological signal in data, the observed number of modes of a seriation solution based on correspondence analysis is compared to a distribution of number of modes generated by randomization of the original data table. A quantitative measure of the goodness of fit is presented. The method is tested on two data sets: 1) archaeological data with a known chronological ordering 2) non-archaeological data without a chronological patterning. The method successfully detected a significant chronological signal in the former, and failed to detect it in the latter.

Removal of Rock Art Affected by the Raising of the Clanwilliam Dam Wall,Western Cape Province,South Africa: Techniques and Procedures

The commissioning by South Africa’s Department of Water and Sanitation of a new and higher wall for the Clanwilliam Dam will increase dam storage and provide additional water for emerging and existing commercial farmers. But there is a cost to South African heritage. The raising of the wall will flood 27 rock art sites as well as other archaeological and historical resources. In partial mitigation of this impact on heritage the removal of particular pieces of rock art was approved by Heritage Western Cape, the provincial heritage agency. This report focuses on the removal process and techniques used to cut out three pieces of rock art under the management of PGS Heritage between 18 April 2016 and 7 May 2016 from the sites designated CDE02 and CDW10. Publication of the techniques used and the procedures followed will add to the sparse literature on rock art removal and increase the accessibility and availability of information about the removed stones.     

Vagueness and Archaeological Interpretation: A Sensuous Approach to Archaeological Knowledge Formation through Finds Analysis

The rapid development of natural scientific methods coupled with the recent popularity of new materialist philosophies in archaeological theory has raised discussion about the possibility of a return to empiricism in archaeology. While empiricism as a pragmatic philosophy is in line with archaeology’s hands-on character, the recent development has left some concerned about the vanishing role of vagueness and ambiguity in archaeological interpretation. In this setting, the exactitude of natural scientific methods is seen as a process of simplification that compromises the tacit dimensions of archaeological knowledge. This article discusses vagueness as an elementary part of all archaeological knowledge formation, with a particular emphasis on the role of perception and senses in finds analysis. Archaeological finds analysis is explored as an example of epistemologically vague and creative hypothesis formation.     

Physical activity and social status in Early Bronze Age society: The Mokrin necropolis

This paper investigates the social structure of an Early Bronze Age society whose members were buried at the necropolis of Mokrin (Serbia, Southeastern Europe), by comparative analysis of musculo-skeletal markers (MSM) of activity and social status as induced on the basis of grave contents. The main objective of the analysis is to determine whether quantitative and qualitative differences in activity are related to social status. Besides using an overall measure of activity, we attempted to isolate different qualitative aspects (facets) of activity through factor analysis of MSM scores. No correlation between social status and overall labor intensity was found. However, there are clues that social status and a single facet of activity are related. Positive correlation between vertical status and the intensity of use of upper arm and shoulder muscles was found among male individuals, while negative correlation between the aforementioned variables was found among the females. The general conclusion based on the results of this study is that there is no simple correlation between the overall labor intensity and social status.
