With the support of national policy of building Yunnan into a gateway in China’s opening up to the Southwest, Yunnan Province offered the great opportunity for second time of starting an undertaking for tourism, and the landscape agriculture welcomes a new development opportunity. On the...

In this paper, a stochastic Lotka–Volterra competitive model with time-dependent delays is investigated. Sufficient conditions for global asymptotic stability of the positive equilibrium are established. The obtained result demonstrates that time-dependent delays have important impacts on the...

In this paper, the deterministic and stochastic SIRS epidemic models with nonlinear incidence are introduced and investigated. For deterministic system, the basic reproductive number R0 is obtained. Furthermore, if R0≤1, then the disease-free equilibrium is globally asymptotically stable and...

In this paper, we analyze in quantitative terms the influence of family control on the pattern of corporate investment, using firm-level data from Indonesia, Korea, Malaysia, the Philippines, and Thailand to regress the investment function and focusing on the family ownership structure that...
