Air pollution can have a significant influence on the weathering of monuments and on the deterioration of museum objects and prehistoric cave paintings. Three important mechanisms of stone weathering will be discussed, and an overview of analysis techniques invoked for the assessment of the degradation processes will be given. The effects of several air pollutants on works of art are reviewed, ...

Dance has been with us since prehistoric times. Now the psychiatric profession is beginning to accept its potential as a means of treating mental disorder.

In an extension of the work of Drs. Hunt and Lipo published in Antiquity (2005), I surveyed the prehistoric roads of Rapa Nui (Easter Island) using ArcGIS software and satellite images of the island. A pre-determined set of criteria was utilized, though there was much potential for error with both false positives and negatives. A great deal of progress was made in identifying potential location...

We have been searching for evidence of Chagas disease in mummified human remains. Specifically, we have looked for evidence of alteration of intestinal or fecal morphology consistent with megacolon, a condition associated with Chagas disease. One prehistoric individual recovered from the Chihuahuan Desert near the Rio Grande exhibits such pathology. We present documentation of this case. We are...

We consider the empirical relevance of two opposing hypotheses on the causality between income and democracy: The Democratic Transition claims that rising incomes cause a transition to democracy, whereas the Critical Junctures hypothesis denies this causal relation. Our empirical strategy is justified by Unified Growth Theory, which hypothesizes that the present international income differences...

The delta 15N values of bone collagen from Eskimos and from Northwest Coast Indians dependent on salmon fishing are about 10 per mil more positive than those from agriculturalists in historic times. Among prehistoric humans, two groups dependent on marine food sources show bone collagen delta 15N values that are 4 to 6 per mil more positive than those from two agricultural groups. The nitrogen ...
