Due to the rapid development,Internet has become the main field for brand building.Under this circumstance,the image of the brand is always consistent with the consumers' perception.Therefore,this study uses the method of text mining of search engine to explore the categories of brand archetype based on Brand Personality Theory from the perspective of Internet.The results find that 12 brand archetypes,including caregiver,sage,hero,innocent,dominator,creator,vitality,explorer,stylish woman,lover,cooperator,and vogue gentleman,have a high degree explanation.Deeper study uses case study to verify the reasonability and effectiveness of the classification standard. 展开更多

The work of world crop germplasm resources are increasingly emerging the developing trend of globalization in collection scope, systematization in resources management, modernization in existing equipments, standardization in technical specification and informationization in shared service. This paper gives you an introduction on current situation of distribution of tropical crop germplasm resources, in-situ conservation, collection and preservation, evaluation and appraisal and innovation and utilization in china; analysis on existing key problems in protection and utilization of China's tropical crop germplasm resources; proposal of complementary study and collection and construction of geographical information base; reasonably layout of plantation and upgrade and preservation of equipments; development and research of related technical standards and carry-out of system evaluation and appraisal; improvement of share mechanism and efficiency; innovation and breakthrough in key points; and talents training and maintenance of work continuance, etc. Basing on these, the proposal of protection and utilization of China's tropical crop germplasm resources are further strengthened. 展开更多
