With the rapid development of electronic commerce, supply chain management is facing more and more new challenges. Therefore, it is particularly important to study the development of clear direction of supply chain. However, the supply chain is composed of different interest subjects, each subject in order to achieve the maximization of their own interests and adopt different measures, is a complex, huge system, has brought the huge challenge to the supply chain management. In this paper, the research on Supply Chain Management in the current situation, characteristics and the modem supply chain management are summarized, and combined with new challenges of supply chain management to predict future research direction is the development of supply chain management, in order to make the supply chain management to the greatest extent satisfy the consumer e-commerce mode increasingly popular. 展开更多

In indigenous and contemporary societies, different elements of social and political institutions have come up with various inner mechanisms that are unique to their societies that can adjudicate in conflict situations. In traditional, indigenous Yoruba societies, agba (elders) were usually relied upon as agents and institutions of conflict resolution in view of certain qualities possessed by this category of people. This paper focuses attention on the role of agba (elders) in conflict resolution at various levels of Yoruba life. We acknowledge that agba (elders) have performed these roles in traditional, indigenous Yoruba societies. The opinion expressed in this paper is that agba, as theoretical and practical conflict resolution mechanism, can be philosophically developed and used as an alternative model to the current means of resolving conflicts through wars and terrorism and other forms of violence by aggrieved individuals and groups in national and international arenas. 展开更多

By applying the con- traction mapping fixed point theorem, we prove the existence of unique almost periodic positive solution. Moreover, we investigate the exponential stability of Mmost periodic solution by means of Lyapunov functional. 展开更多
