On April 20, 2010, British Petroleum’s Deepwater Horizon drilling rig in the Gulf of Mexico exploded, creating the largest oil spill in U.S. history. Analysis of 1,161 BP tweets during the crisis response reflected unexpected reputation repair strategies and responsibility attribution. Situational Crisis...

The role of the banking balance sheet as the source and transmitter of systemic risk is explored. We find that the key balance sheet channels of systemic risk are; (i) bank capital structure choice, (ii) interconnectedness and interdependencies among firms, (iii) correlations of asset composition and...

estimators of diversifiable risk and portfolio expected returns to reflect normal market conditions. GARCH (General Auto - Regressive Conditional Heteroskedasticity) models are then used to make forecasts of given time series, from which future predictions of Non - Diversifiable risk, Diversifiable risk...

This paper proposes a novel hybrid algorithm based on quantum-behaved particle swarm optimization (QPSO) algorithm and Nelder-Mead (NM) simplex search method for continuous optimization problems, abbreviated as QPSO-NM. This hybrid algorithm is very easy to be implemented since it does not require continuity...

In this paper, the evolution and control of society risks caused by severe emergency infectious disease will be analyzed and studied. Firstly, the evolution chain of society risks caused by severe emergency infectious disease is constructed to analyze the evolution rule of society risks and identify...
