Preliminary Report Of Animal Bones From Hrísheimur, Mývatn District, Northern Iceland, Sophia Perdikaris, Thomas H. Mcgovern

School of Global Integrative Studies: Faculty Publications

In 2000 and 2001 the FSl / NABO project Landscapes of Settlement in Northern Iceland collected animal bones from the heavily eroded site of Hrísheimur south of lake Mývatn. The 2001 season produced a substantial archaeofauna from a 2 x 2 meter test excavation of a midden deposit that apparently fills a small sunken-feature structure. While further excavations are planned to collect more material and to better understand the deposit and site as a whole, it may be useful to provide an interim overview of the bone materials recovered from the largest context (003) of the midden deposit tested in …

School of Global Integrative Studies: Faculty Publications

Executive Summary

During rescue excavations in downtown Reykjavík in 1999 nearly 100 kg of well-preserved animal bone was recovered in investigations at Tjarnargata 3 C by Fornleifastofnun Islands (FSÍ) directed by Mjöll Snaesdóttir. This bone collection (or archaeofauna) was largely sieved (4 mm and 1 mm mesh wet screen) and represents one of the largest archaeofauna recovered from Iceland to date. Analysis was carried out at City University of New York’s Northern Science & Education Center’s two zooarchaeology laboratories at Brooklyn College and Hunter College in 2000-01. The analyzed bone materials were returned for long term curation at the National …

Discounting And Reciprocity In An Iterated Prisoner’S Dilemma, David W. Stephens, Colleen M. Mclinn, Jeffrey R. Stevens

Jeffrey Stevens Publications

The Iterated Prisoner’s Dilemma (IPD) is a central paradigm in the study of animal cooperation. According to the IPD framework, repeated play (repetition) and reciprocity combine to maintain a cooperative equilibrium. However, experimental studies with animals suggest that cooperative behavior in IPDs is unstable, and some have suggested that strong preferences for immediate benefits (that is, temporal discounting) might explain the fragility of cooperative equilibria. We studied the effects of discounting and strategic reciprocity on cooperation in captive blue jays. Our results demonstrate an interaction between discounting and reciprocity. Blue jays show high stable levels of cooperation in treatments with …
