متن کاملCatastrophe Archetypes
We propose an Integrated Systemic Theory of Catastrophes (ISTC) using System Dynamics to model and to understand common systemic structures and behaviours of catastrophes. Current catastrophe research concentrates on a specific field and does not capture complex multi-field catastrophe scenarios that cannot be reduced to a single scientific field. For example, when looking at famines the elemen...
متن کاملElectromechanical Catastrophe
A transducer is a system that couples two loads. For example, an electromechanical transducer couples a mechanical force and an electrical voltage. A two-load, nonlinear system can exhibit rich behavior of bifurcation, which can be displayed in a three-dimensional space, with the horizontal plane representing the two loads, and the vertical axis representing the state of the system. In this thr...
متن کاملAn error catastrophe in cancer?
A comparison between the evolution of cancer cell populations and RNA viruses reveals a number of remarkable similarities. Both display high levels of plasticity and adaptability as a consequence of high degrees of genetic variation. It has been suggested that, as it occurs with RNA viruses, there is a threshold in the levels of genetic instability affordable by cancer cells in order to be able...
متن کاملDo Firms Manage Catastrophe and Non-Catastrophe Risks Differently?
Recent disasters and historical insurance payouts have triggered renewed interest in how firms manage their left-tail exposure. Using a unique dataset of fully described insurance policies purchased by large U.S. firms, we provide the first consistent estimates of premium elasticity of corporate demand for insurance for both catastrophe and noncatastrophe risks. We do so by combining this datas...
