In this study, we use restlessness as an input for a rice crisis indicator, since restlessness rather than rice price provides a comparable year-to year context. We outline the significant increase in the use of unprecedented restlessness (UR) as an indicator for rice crises. The UR approach involves a precedence analysis, in contrast with the existing approach, the price shock analysis. We test UR as a new indicator for rice crises at the national level, which can be applied in Asia and other c...

The purpose of this research is to determine the unwanted condition as a strategic criterion in measuring the economic resilience of a city A new approach in determining economic resilience was developed to overcome the weaknesses of the index method commonly used internationally Based on the output of this research, the development priority program for each city becomes distinctive depending on the status of the city’s economic resilience Quality improvement programs are used for cities that do...

Abstract In this chapter, we introduce a novel chaotic system with a closed curve consisting of four quarter circles of equilibrium points. The equilibrium curve is symmetric about the straight lines x = ± y . Thus, the new chaotic system exhibits hidden chaotic attractor. The complex behavior of the new chaotic system has been verified by using phase portraits and Lyapunov exponents. We also show that the new chaotic system has multistability and coexisting chaotic attractors for different init...

Natural disasters due to excessive rainfall often cause huge losses in the form of impacts including casualties and economic losses. To minimize casualties, disaster mitigation is needed, while financing for disasters (emergency response) and financing after disasters (rehabilitation and reconstruction) can be carried out with insurance. This paper aims to determine mitigation efforts and insurance premiums for natural disasters. The method as a mitigation effort is studied based on several meth...

In this paper, a fractional-order model of a financial risk dynamical system is proposed and the complex behavior of such a system is presented. The basic dynamical behavior of this financial risk dynamic system, such as chaotic attractor, Lyapunov exponents, and bifurcation analysis, is investigated. We find that numerical results display periodic behavior and chaotic behavior of the system. The results of theoretical models and numerical simulation are helpful for better understanding of other...
