The Role of Telematics in Integrating Ireland into Europe's Information Society

This article is an evaluation of Ireland's participation in the Telematics Applications Programme (TAP), which was part of the European Commission's Fourth Framework Programme for the period 1994-1998. TAP was primarily concerned with public sector bodies and their ability to adapt to the Information Society. The article explores Irish participation in the programme and examines the contribution of this participation to the clustering of telematics experimentation within Ireland and to the increasing integration with other European regions arising from project networks. The role of the TAP programme in furthering Europe's information society in Ireland is assessed.     

Bear dentine aspartic acid racemization analysis: a proxy for the dating of Pleistocene cave infills

A high correlation between chronometric determinations based on aspartic acid racemization ratios and radioactive dating methods is described from samples of cave bear (Ursus deningeri and Ursus spelaeus) dentine. For samples from a very restrictive environment, as deep cave bear sites are (in view of their highly stable geochemical and thermal history), an age calculation algorithm was obtained. It has been found that there is a very close relationship between collagen preservation, from total aspartic acid in the > 3500 D fraction, and the amino acid racemization.     

The Material Characterization of a Santamarian Ceremonial Axe

The characterization of a ceremonial bronze axe is described. The axe is assigned to the Santamarian culture of north‐west Argentina, c. 1000–1470 ad, and was selected to increase presently limited knowledge of prehistoric metallurgy in the Andean region of Argentina. The characterization methods used were electron probe microanalysis, gamma radiography, X‐ray diffraction, optical metallography and microhardness testing. The axe was well cast in a bivalve mould, with the only defects in the area of an ancient fracture. The analysis showed that it is made from a tin bronze with a, probably, accidental addition of lead. Arsenic was found as a surface contamination, probably deriving from arsenic in the water of the stream in which the axe was found. The axe shows that Santamarian craftsmen had the skill to decorate the axe in an artistic style with a strong local accent while providing a functional, annealed and cold‐worked cutting edge.     

An investigation of soil phosphorus distribution within occupation deposits from a Romano-British hut group

A simple scheme for soil sampling and subsequent analysis for total soil phosphorus using perchloric acid digestion is described and its application illustrated by samples from the native farmstead of the Roman period at Cefn Graeanog in North Wales. The floor deposits of three distinctive buildings were analysed, and the data obtained enhanced by Trend Surface Analysis to produce generalized maps of the phosphorus distribution, together with levels of significance of such distribution patterns. These were then used to clarify the details of the interpretation of the usage of the various types of building. Data for soil phosphorus concentration clearly reveal the pattern of erosion of constructed floors, the presence of features such as hearths and drains, and can be used to reveal patterns not otherwise discernible by excavation techniques.     

The digital restoration of painted patterns on the No. 2 Qin bronze chariot based on hyperspectral imaging

The No. 2 Qin bronze chariot unearthed from Qinshihuang's Mausoleum is world famous for its huge size and colourful painted patterns. However, since it had been buried for a long time and was affected by its harsh environment, its painted patterns have been severely damaged. The traditional restoration methods, which mainly rely on expert experience, are manual, inefficient and lack scientific support. Moreover, to protect the important cultural relics, any invasive operations, such as sampling analysis, are strictly prohibited. This paper presents a method that combines hyperspectral imaging and computer technology for the digital virtual restoration of the bronze chariot's patterns. It is non-destructive, more efficient and more scientific. The method reproduces the damaged patterns with the following approaches: restoring the missing edges of the patterns; and distinguishing the different pigments. The obtained result implies that the method can digitally reproduce some of the damaged patterns, and that it can be used as a reference for recreating the patterns of the other painted bronze.     

Reconstructing subsistence at the Yingpanshan and Gaoshan sites in Sichuan province,China: Insights from isotope analysis on bone samples and charred crop remains

During the Neolithic period, the Chengdu Plain was a key region where two important crops, rice and millet, were cultivated together. Millet was probably introduced from north-western China c.3500–3300 cal. bce , and rice came from the Middle Yangtze River c.2600 cal. bce . In this study, human and faunal remains, as well as charred crop grains, were collected from the Yingpanshan (3300–2600 cal. bce ) and Gaoshan (2500–2000 cal. bce ) sites where the dominant crop was millet and rice, respectively. Carbon and nitrogen isotope analyses were conducted on human bones and the ecofact samples in order to reconstruct the subsistence at the sites. The results indicate that the diets of two individuals recovered from the Yingpanshan site consisted of both C₃- and C₄-based foods, predominantly the former. By contrast, Yingpanshan pigs consumed a large quantity of C₄ fodder. This result, combined with the ecofact evidence, suggests that millet was the main crop at the Yingpanshan site. It also highlights the fact that the two Yingpanshan individuals might be non-locals and/or belonged to later periods. On the other hand, the diet of the Gaoshan community was dominated by C₃-based foods. When considering the archaeobotanical evidence at Baodun, a site contemporaneous with and near to the Gaoshan site, it can be stated that rice was an important food resource for the Gaoshan community. This study also suggests how crops were managed at the two sites. The Yingpanshan people might have used manure for growing millet. Both manuring and irrigation might have also been practised by Gaoshan's rice farmers. However, more studies are required to understand the extent of manuring and irrigation in their agricultural economies.
