The way of HNBM rising to the national strategy was analyzed through the aspects of technology features, historical characteristics, irreplaceability, function and value hierarchy, and the key problems. As the major achievement of the practice of scientific research and historical selec- tion, HNBM played an irreplaceable role in the climatic conditions, scientific breed- ing, and seed production in disaster relief, protecting the safety of the seed industry and Iocational advantages. Based on the analysis on the functions, values and ex- isted problems of HNBM, the function and value hierarchical structure of HNBM was established through introducing concepts of value engineering, industrial clusters and regional economy. But to fully achieve the industrial clustering development and functional values of HNBM, it needed to solve the key problems existed in top-level planning, experimental bases, system design, hardware construction and ecological security. Some suggestions were put forward in this paper, including setting up key scientific research protection zones, improving the regulations and policies safeguard mechanism and management system of HNBM, drawing up and carrying out the base development planning of HNBM, and striving for financial support from national policies.展开更多

The increase of land area alleviated the contradiction of supply and demand between human and land, which provided the guarantee for agricultural production and industrial development. However, marine ecological environment has been seriously damaged due to the increasing scale of tideland reclamation. This paper took the Hangzhou Bay in the Yangtze River Delta as a study area to explore the evolution law, socioeconomic effect and eco-environmental effect of reclaimed land from 1985 to 2015. The result showed that as follows:(1) The area of tideland reclamation was 460.67 km^2 with 16.57% cultivated land and 15.93% construction land, and its land use was inefficient;(2) Land use change has spatial and temporal difference, the speed of tideland reclamation had been increasing from 1985 to 2015 in time and the scale of reclaimed land in the southern(84.07%) of Hangzhou Bay was larger than the northern region(15.93%) in space;(3) The evolution law of land use was from tideland to swampland and coastal waters to agricultural facility land, to cultivated land to industrial-mining land to idle land, rural-urban construction land, and formed obviously hierarchical structure;(4) Effect analysis of land use change found that the socio-economic effect had increased but the eco-environmental effect had decreased from 1985 to 2015, it reflected socio-economic effect was acquired through sacrificing eco-environmental effect;(5) It pointed out the existing problems on land extensive inefficient, environmental degradation and economy excessive growth without scientific planning, and offered some suggestions in land comprehensive improvement project, industrial transformation and upgrading and scientific planning and legal safeguardto promote sustainable development in the Hangzhou Bay in the new period.展开更多

An invention, a president, the occurrence of an organization, a historical lesson may directly or indirectly change accounting regulations, and even trigger an accounting revolution. We will put a variety of significant impacts on an accounting, so as to get a fundamental understanding of the close relationship between such events and accounting events, including innovation of accounting theory, and accounting practice; we adopted the "table-style" form of papers, with many self-evident and intuitive tables, we compile a series of major historical events reasonably. Only in accordance with evolution of objective environment, can we design proper accounting practice, and thus innovate and develop accounting.展开更多

Based on the theory of grey system, this paper established GM(1,1) grey predict model for the first time to forecast The number of Scitech novelty search item and The staff number of Sci-Tech Novelty Search. The predicting results are almost close to the actual values, which shows that the model is reliable so that the models could be used to forecast the two factors in the future years. The study will help the scientific management of Sci-Tech Novelty search work for Novelty search organizations.展开更多

The cloud classes are organised with one class from each country in the subjects: language, science, math, social science/history. The teachers from the three classes work together to design teaching they conduct together with assignments the students will be able to solve only in collaboration with their fellow students in the three classes. The three year project ends in 2014 but already now there are some interesting findings on how transnational teaching collaboration works for teachers and students. This paper will focus on the different uses of web based tools of synchronous and asynchronous communication and discuss challenges and benefits in regard to learning and pedagogy with virtual classroom.展开更多

The clustered and visualized document co-citation network of the humor processing knowledge domain was analyzed in terms of common topics and content of co-cited references. Emerging trends of humor processing were detected through reference citation bursts. The combined dataset of 816 bibliographic records and 42,687 references was compiled through a basic topic search. In order to ensure adequate coverage of the field, the search was expanded to include literature that referenced literature found in the initial basic topic search. Results produced a document co-citation network of humor processing with ten clusters, which showed that social cognition and fMRI study both served as important foundations for work in this knowledge domain. Personality studies in humor processing as well as research about the right hemisphere's role in humor processing also received considerable attention. These key areas of study accounted for 4 clusters. The remaining six clusters included studies on sexual selection, figurative language, prejudice, facial expression, sleep deprivation and infant humor perception associated with the knowledge domain. In this study, burst detection in references revealed topics of high interest to researchers as well as emerging trends in humor processing research.展开更多
