GAMBLING IS HARD WORK: CARD PLAYING IN TIWI SOCIETY

This paper examines the gambling activities of Tiwi women and men of North Australia and situates the activities within the anthropology of work. It is shown that gambling for money redistributes an unequal resource (wages and pensions) while the derivative game using beer rather than money redistributes an equal resource unequally. The principal conclusion is that for women the activity may be equated to foraging — a low risk activity but fundamental for personal status in that it is directed toward providing daily subsistence, while for men the activity closely resembles hunting — a high risk activity where success is less likely but also essential for personal status.

pXRF: a study of inter-instrument performance

Integrating portable X-ray fluorescence (pXRF) instrumentation into archaeological investigations has generated as much interest as skepticism because several characteristics of the technique limit analytical accuracy and precision. This paper seeks to explore inter-instrument performance in order to assess the potential pXRF instrumentation has in examining the elemental composition of lithic raw materials. Two pXRF instruments, Delta and Omega models both manufactured by Olympus Innov-X Systems, were utilized to obtain the trace element signatures of five fine-grained volcanic sources and four obsidian sources in the Great Basin. We compared the two portable instruments to a wavelength-dispersive instrument extensively calibrated with geologic standards and to a commercial benchtop energy-dispersive system. Our results suggest that the relationships between the data produced by these different instruments are complex, and as we look to the future of pXRF use in archaeological analysis we argue that that the same strict protocols applied in laboratory-based XRF analyses, involving instrument calibration, evaluation of inter-instrument performance, and comparison to accepted geologic standards, need to be applied in pXRF analysis.
