AMS dating of rock art in the Laura Region, Cape York Peninsula, Australia - protocols and results of recent research

The authors describe rock art dating research in Australia using the oxalate method While the array of dates obtained (which range from c. 1200 to c. 25000 BP) show a satisfactory correlation with other archaeological data, there are mismatches which suggest that some motifs were often imitated by later artists, and/or that the mineral accretions continued to form periodically, perhaps continuously, as a regional phenomenon over a long period of time.

Art after 9/11

This article examines ways in which art can help broaden understandings of contemporary security challenges, especially in view of the limits of conventional forms of strategic and policy analysis. The article focuses especially on responses to 9/11 in literature, the visual arts, architecture, and music, and considers some epistemological questions about the status of art as a way of knowing political events, like those of 9/11, that escape state-based forms of security analysis.
