However, because DNA can exhibit marked differences among morphologically similar species, DNA barcoding offers a potential means for oyster identification. We analyzed the complete sequences of the cytochrome oxidase subunit I （COI） of five common Crassostrea species in China （including Hong Kong oyster C. hongkongensis, Jinjiang oyster C. ariakensis, Portuguese oyster C. angulata, Kumamoto oyster C. sikamea, and Pacific oyster C. gigas） and screened for distinct fragments. Using these distinct fragments on a high-resolution melting analysis platform, we developed an identification method that does not rely on species-specific PCR or fragment length polymorphism and is efficient, reliable, and easy to visualize. Using a single pair of primers （Oyster- COI-1）, we were able to successfully distinguish among the five oyster species. This new method provides a simple and powerful tool for the identification of oyster species.展开更多

Based on Chinese culture which can be characterized as lack of afterlife, the pattern of Chinese economic development has distinctive features relative to the economy of the Western world, even to that of Japan and Korea. This paper argues that culture influences economic development through two paths： One is that some cultural factors, as certain institutions, have effects on cost, especially transaction costs. Another point is that culture forms people＇s preferences and influences people＇s choices. With the influences of Chinese culture, Chinese have a weak sense for legal obedience and strong inclination for ＂free riding＂, this would increase social transaction costs. The family centered tradition of Chinese society results in Chinese features such as being good at individual struggles but poor at cooperation, the alienation between civil society and government, a strong sense for competition and a weak sense for legal obedience, seeing material wealth as important and neglecting scientific innovation. Traditional Chinese culture also has effects on the developmental pattern of Chinese enterprises展开更多

Adjusted to media convergence and the needs of network cultural industry development, China has made the lawmaking of media transform from practical service oriented management to functional oriented management of media. This strategy aims to prevent network medium risk effectively according to network communication regularity.展开更多

After the founding of the People＇s Republic of China, he created and continuously improved the socialist economic system and the corresponding political system, led the large-scale socialist economic, political and cultural construction, established the institutional preconditions, ideological guarantees and material basis for socialism with Chinese characteristics, and brouglat about a favorable external environment for China＇s socialist construction. During this process, Mao originated a series of theories about China＇s socialist construction. In proposing to achieve the second combination of the universal truth of Marxism with China＇s realities and to go China＇s own way and explore a path of building socialism which suits China＇s national conditions and has Chinese characteristics, he madea great theoretical contribution to the history of China＇s socialist development. His ideas provided ample ideological gestation and theoretical preparation for the second historic leap of the sinicization of Marxism. They served not only as the starting point of the history and logic of the theory, road and system of socialism with Chinese characteristics but also as one of the guiding principles of China＇s revolution, construction and reform. Mao＇s exploration left us with experience of success and lessons from mistakes, both of which enabled us to store up valuable experience and important inspiration for today＇s construction of socialism with Chinese characteristics. Therefore, whether in terms of historical practice or theoretical logic, Mao is the great founder, explorer and pioneer of the cause of socialism with Chinese characteristics.展开更多
