Glassmaking using natron from el-Barnugi (Egypt); Pliny and the Roman glass industry

Pliny the Elder describes the discovery of a process for making natron glass, which was widely used for much of the first millennium bc and ad. His account of glassmaking with natron has since been corroborated by analyses of archaeological glass and the discovery of large-scale glass production sites where natron glass was made and then exported. Analyses of Egyptian natron have shown it to be a complex mixture of different sodium compounds, and previous experiments to make glass with Egyptian natron have been unsuccessful. Here, natron from el-Barnugi in the Egyptian Nile delta, a site which also probably supplied Roman glassmakers, is used to produce glass. The experiments show that high-quality glass, free of unreacted batch or bubbles, could have been produced from natron in its unprocessed form in a single stage, that larger quantities of natron would be required than has previously been anticipated, that the presence of different sodium-containing compounds in the deposit aided melting, and that negligible waste is produced. The implications for the identification of glass production sites, for the organisation of trade and for the supply of natron within and outside Egypt are discussed in the light of Pliny’s accounts.     

A Note on Adjusting National Input-Output Data for Regional Table Construction

Regional analysts face a trade-off between timeliness and detail of commodity-industry data. The trade-off exists because the Bureau of Economic Analysis national aggregated annual update tables are published for years more recent than those for which the disaggregated benchmark accounts are available. Conventional wisdom holds that regionalization should precede aggregation, so a disaggregated foundation table is preferred to an aggregation of that same table. This paper shows that the Table Disaggregation and Adjustment (TDA) method of Jackson and Comer (1993) produces a better foundation for regionalization than an unadjusted benchmark, price-updated benchmark, or aggregated annual update table.     

On “political education”

Three forms of the Situational Attitude Scale (SAS), measuring attitudes toward Aborigines, New Australians and a neutral form, were administered to 314 white Australian university and college students (New Australians are immigrants from non‐English speaking European countries). Data were analysed, using fixed effects analysis of variance at .05 and Scheffé post hoc tests at .10. Results showed that white Australian students have a positive bias in favour of both Aborigines and New Australians, although they were more negative toward New Australians. The results support the general hypothesis that the more culturally visible the minority group, the more likely the group is to be perceived unfavourably by the majority culture. Results are discussed in terms of similar findings in Denmark and Japan.     

SHOPPING AND LEISURE: IMPLICATIONS OF WEST EDMONTON MALL FOR LEISURE AND FOR LEISURE RESEARCH

In the context of three alternative approaches to the meaning of leisure (activity, time, and experience), this article uses West Edmonton Mall (with its vast array of shops and unique complex of recreational facilities) as a starting point to explore four relationships between shopping and leisure. These are: independence (shopping as purchasing); shopping for leisure (the purchase of goods for use in subsequent leisure time); shopping and leisure (when shops and leisure facilities are juxtaposed in a single facility like West Edmonton Mall); and shopping as leisure (when shopping begins to take on the attributes of leisure as an experience). It is concluded that the last category offers the most interesting questions for future research.
