Non-destructive fabric analysis of prehistoric pottery using high-resolution X-ray microtomography: a pilot study on the late Mesolithic to Neolithic site Hamburg-Boberg

The characterisation of prehistoric pottery fragments presents a quite complex task. In provenance studies, petrographic and chemical analyses of the ceramic materials are employed to investigate potential production areas in respect to the geolocial background. Moreover, also the production technology of the firing process, as well as the forming techniques used by the prehistoric potters are of great interest. Their investigation is most often accompanied by a destructive preparation of the samples. In this paper, we want to present high-resolution X-ray microtomography (μ-CT), a non-destructive and non-invasive method, as a supplementary research tool in the study of prehistoric pottery.     

The Price of Peace: A Predictive Model of UN Peacekeeping Fiscal Costs

This study devised a predictive model of peacekeeping fiscal costs based on an analysis of all United Nations peacekeeping operations since 1945. Our results indicate that the costs of a peacekeeping operation were significantly influenced by the length of that mission and the size of the force deployed. Beyond these factors, the historical development from observer to second generation missions has produced more costly operation.     

The pattern of spondylosis deformans in prehistoric samples from west‐central New Mexico

A Pre‐Columbian skeletal sample (n=42) from two ancestral Pueblo sites in the Rio Grande valley of west‐central New Mexico was examined for frequency and severity of spondylosis deformans (vertebral osteophytosis). No significant sex differences were detected. Degenerative changes in the collective sample are generally confined to no more than well‐defined horizontal lipping at the joint margins. Advanced proliferative osteophytic change is infrequent even in the oldest age category. Not surprisingly, the lumbar vertebrae were the most frequently and most severely involved vertebral segment for all three adult age cohorts defined. The cervical vertebrae were the least involved. This pattern generally conforms with observations made on other archaeological samples from west of the Mississippi River, but it contrasts with the general pattern of more extensive cervical involvement in Pre‐Columbian North American samples from the Eastern Woodlands. This possible east–west difference is hypothesized (Bridges, P.S. 1994. American Journal of Physical Anthropology 93: 83–93) to be related to differential burden bearing habits.
