Shanghai is a megacity located in a hazard-prone region, but one in which local residents have not actively engaged in disaster risk management. This paper aims to identify factors of perception that influence residents' propensity to adopt risk-mitigating measures. It presents results of a structured questionnaire survey administered to Shanghai residents. Results show that risk-mitigating measures are deemed to be important if people: (1) have frequently experienced extreme weather; (2) believe that extreme weather events are severe in Shanghai; and (3) are concerned about other public risks confronting international society, such as energy security and terrorism. It is important to note that the third point has resulted in greater impacts than the other two factors. A cultural explanation is offered in this paper. Public risk awareness emanates from a generic concern over the security of the human world. This generic concern acts as a socio-cultural backdrop that contextualises the ways in which individuals respond to natural hazards. The significance of this factor indicates the need for broadening the analytical scope of risk perception research in China. These findings are useful for local policymakers, emergency managers and community and aid organisations seeking to develop creative strategies for risk education and communication.

Based on ESTs of Japanese flounder (Paralichthys olivaceus) in the public database, EST-SSR makers were developed after mining and evaluating SSRs in them by bioinformatics methods. 5 927 non-redundant ESTs of Japanese flounder were screened and 390 SSRs were mined out. The frequency of these EST-SSRs was 7.95% and the average distance of distribution was 7.9 kb in non-redundant ESTs. The dinucleotide repest motif was dominant type (59.02%) with repeat motif AC being the most common (16.91%). The distribution of trinucleotide, tetranucleotide and hexanucleotide repeats were dispersive. 30 primer pairs for EST-SSRs were designed, 27 primer pairs showed the amplification, and 17 primer pairs showed polymorphisms, the rates of polymorphic EST-SSRs were 62.96% with the alleles per locus ranging from 2 to 6 (mean 3.5). The observed (HO) and expected (HE) heterozygosities of these EST-SSRs were 0.280.92 and 0.31550.8033, respectively. Two EST-SSR loci significantly deviated from the HardyWeinberg equilibrium (HWE) expectation, and theremaining 15 loci were in HWE. These new EST-SSR markers would provide sufficient polymorphism for population genetic studies and genome mapping of Japanese flounder.

ABSTRACT:The history of tourism development in Guangxi is short, but the growth rate is very alarming. Because economic growth is subject to tourism resources, tourism market, the level of socio-economic development of the region, regional economic structure and a series of natural and cultural factors that make tourism economy in space showing non-equilibrium features. From the geographical pattern of the macro economy, the process of industrialization in Guangxi on spatial development can be basically divided into three different economic zones, namely mature eastern zone, growth in the near-developing western areas and western areas of the original. But only as a framework and general background of Guangxi tourism spatial layout, and specializes in Guangxi economic space tourism is still rare for layout, paper tries to use methods of regional economics, quantitative indicators do describe, analyze Current Situation of Guangxi tourism unbalanced development of its causes.
