Abstract

Corporate distress has gained significant importance since the global financial crises and the default of global companies like Enron, WorldCom, American Airlines, Merrill lynch. Keeping in view the scope of this study, block holding in the companies are considered an important driver for corporate default. This study aims to find out whether block holding may have any contribution towards a firm heading to default, although block holding has been supported earlier for solving the agency problem and value maximization for shareholders. The study also addresses the block holding for its influence on the company's performance which may lead to corporate default. The study has been conducted on the Singapore public listed companies and found that the defaulted companies have high concentration of shares as compared to non-defaulted companies. Moreover, this paper provides useful information on the impact of ownership concentration and block holders on firms' default risk. [ABSTRACT FROM AUTHOR]

Abstract

The nonlinear dynamics of low-frequency (in comparison with electron gyro-frequency) electrostatic disturbances in nonuniform dusty electron-positron magnetoplasma with equilibrium sheared flow is investigated. In the linear limit, a local dispersion relation has been derived and analyzed. On the other hand, in the nonlinear case, the temporal behavior of the nonlinear dissipative system can be expressed as a set of three coupled nonlinear equations, which are a generalization of Lorenz-Stenflo equations that admit chaotic trajectories. The results of our present investigation should be very helpful to understand plasma turbulence and wave phenomena in several laboratory and astrophysical plasma systems. [ABSTRACT FROM AUTHOR]
