Based on a survey to 560 household farms in 6 provincial-level regions of eastern China, this paper studies farmers' application of pesticides, including the amounts of chemical pesticides, use of toxic pesticides and biological pest-control methods. Meanwhile, it summarizes the farmers' perceptions, ranging from pesticides choosing and field application to the awareness on the withdrawal period, possible consequences of overdosing and disposal of the containers. Thereafter, 9 demographic indicators are incorporated as the candidate determinants, including information on the householders, land-using and cropping structure, household income and geographical location. Through the adoption of multivariate OLS and logistic regression models, this paper identifies significant determinants affected farmers' behaviors. Finally, several policy recommendations are put forward, including the countermeasures to increase pesticidal efficiency, decreasing the use of toxic pesticides, improving farmers' capability and awareness on scientific application of pesticides.

In the new rural construction, there are certain development advantages of resource-based rurals, however, there are still bottlenecks in their own development. Basised on the actual survey, used Beimazhong village as an example, we found that the resource-based rural has a series of sustainable development problems: resource depletion, economic restructuring and the lack of technical and management talents. The main path to solve these problems is organizational innovation, viz.building and develping farmers' specialized cooperative, as the same time, all levels of the government and villagers should fulfill their respective responsibilities accordingly. © 2010 IEEE.

A core-shell structured nanocomposite for Hg(II) sensing and removal using superparamagnetic Fe3O4 as the core and silica molecular sieve as the shell is reported. A rhodamine derived sensing probe was covalently grafted into the tunnels of the silica molecular sieve. This core-shell structured nanocomposite was carefully characterized, where its core-shell structure was analyzed and confirmed with electron microscopy images, XRD curves, thermogravimetric analysis and N2 adsorption/desorption isotherms. The sensing performance of the nanocomposite suggested that its emission increased with the increasing Hg(II) concentration, showing emission "Off-On" effect and high selectivity towards Hg(II). The adsorption and removal performance were also investigated and proved to be promising. More importantly, this nanocomposite could be regenerated after usage. © 2014 Elsevier Ltd.

Jidong Economic Zone is an important economic growth pole in Hebei province, also the most dynamic region in economy. Equipment manufacturing industry is a main direction of industrial structure's optimization and upgrading in Jidong economic zone, the share of the proportion of industrial added value increasing year by year. However, there are also some problems such as low enterprise clusters, poor comprehensive supporting ability, and lack of independent innovation capability. The paper summarizes the development characteristics of the equipment manufacturing industry at home and abroad. Then it analyzes the advantages of Jidong Economic Zone and makes strategic positioning for the equipment manufacturing industry's development. Finally, the paper puts forward some development strategies such as integrating into national policy, government supporting, promoting the enterprise's research ability and developing industrial clusters. © (2013) Trans Tech Publications, Switzerland.

The equipment manufacturing industry is the key factor to determine a country's international competitiveness. The paper studies the development characteristics and the status of the equipment manufacturing industry in developed countries and China. Then it puts forward four development directions of the equipment manufacturing in Jidong area: depend on advantageous industries to develop large-scale equipment manufacturing; expand rail transportation equipment manufacturing industry based on the existing foundation; form the Jidong ship and marine engineering equipment industry cluster and attach importance to the development of new equipment manufacturing. © (2013) Trans Tech Publications, Switzerland.
