Overexploitation of Renewable Resources by Ancient Societies and the Role of Sunk-Cost Effects
One of the most persistent mysteries in the history of humankind is the collapse of ancient societies. It is puzzling that societies reaching such high levels of development disappeared so suddenly. It has been argued that overexploitation of environmental resources has played a role in causing the collapse of such societies. In this paper we propose an explanation for the pattern that overexpl...
متن کاملInvestigation of Double-layer Grid Space Structurer Resistance to Progressive Collapse
Considering the vulnerability of double-layer grid space structures to progressive collapse phenomenon, it is necessary to pay special attention to this phenomenon in the design process. Alternate path method is one of the most appropriate and accepted methods for progressive collapse resistant design of structures. Alternate Path Method permits local failure to occur but provides alternate pat...

Climatic conditions have dried up since the late 5th millennium BC as if Paleoclimate research in the northern hemisphere, particularly Iran and neighboring countries, shows unfavorable climatic conditions and several periods of severe drought during 4th millennium BC. Also, based on environmental sedimentological studies on archaeological sites such as Mafin Abad of Islamshahr and Meymanat Aba...
متن کاملOn the Observability of Purely Behavioral Sunk-Cost Effects: Theoretical and Empirical Support for the BISC Model
There is growing interest in whether and how sunk-cost effects for purely behavioral investments occur. In this article, we further discuss Cunha and Caldieraro's (2009) Behavioral Investment Sunk Cost (BISC) model and reconcile Otto's (2010) results with the BISC model predictions. We also report new data from two unpublished experiments that are consistent with the BISC model, and we discuss ...
