This need leads the authors to consider the formation of dynamic virtual organizations tailored to each particular abuse case. In the authors＇ approach the partner selection of these collaborative networks is done through a software tool that combines two technologies from the field of artificial intelligence, specifically multi-agent systems and expert systems. In addition, these partners come from the breeding environment constituted by all the agencies or individuals, either in a region or locality, which have the potential of response.展开更多

In the aspect of marine tourism, Guangxi and ASEAN cooperation has a solid foundation. This paper first gives the concept of the Marine Silk Road, and then analyzes the Guangxi and ASEAN tourism cooperation mechanism of the line, implementation steps and conditions under the 21 century Marine Silk Road strategy in order to provide reference for the related workers.展开更多

China faces unprecedented opportunities for development, although there are many challenges it must face, It has become a strategic choice for all automotive enterprises to implement supply chain management in order to achieve competitive advantages. At present, most researches on supply chain partnerships have been carried out based on enterprises in developed countries. Very few theoretical and empirical studies have been based on developing countries, and in particular, only a few scholars have examined supply chain partnerships in China. Based on the joint ventures, this paper is a review of partner theories and process of partner relationship. With respect to the supply chain partnership strategy and process and partners＇ capability literature, there is limited research on the special background such as joint ventures or Chinese automotive industry. Some literature on partners＇ capabilities is based in favor of the operational aspects.展开更多

Moscow has effectively sacrificed the goals of modernization and development for the sake of geopolitical ambitions. The question about the price of Russia＇s revisionist enterprise is relevant for many states that are not satisfied with the unfair and often discriminating rules of the world order, first of all China. Russia hopes to inspire other states dissatisfied with the ＂unipolar＂ world order to challenge the West more boldly, but the result of its assault on the prin- ciples of nonintervention and territorial integrity might work in the opposite way. The states of East Asia could take a good measure of the risk inherent to embarking on the course of projecting power at the expense of modernization and become even more committed than before to upholding their unique prosperity-producing peace. China has a vested interest in Russian internal stability and must be worried by the prospect of a post-Putin crisis.展开更多
