creatures ever to live on earth had become extinct. Dinosaurs were not the only victims of this "mass extinction." There were many other species that were killed off.

The apparently sudden mass extinction of dinosaurs marks the boundary between the Cretaceous and Tertiary periods.

For American options‚ the effect is unambiguous: Increasing the time to maturity always increases an option’s value because it increases the uncertainty of the spot exchange rate at maturity.

The article by Donald Flynn‚ Gary Pann‚ Mark Keil‚ and Magnus Mähring (October 2009) introduces a practical and good de-escalation management maturity (DMM) model by combining different approaches that have been suggested for managing de-escalation in IT projects. The authors provide a de-escalation management maturity (DMM) model which captures the progressive levels needed to manage de-escalation. De-escalation1 is the art of not escalating a situation and bringing about the
