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.

Occupational differentiation of farmers has important significance for promoting the development of agricultural modernization and the modernization of the State. Occupational differentiation of individual farmers in China is different in degree, and farmers ' occupational differentiation in this article is divided into three types - the professional farmers (undifferentiated ones), part-time farmers and totally differentiated farmers engaged in non-agricultural industries. Based on differences in degree of specialization, these three categories of farmers were compared in the aspects of individual characteristics, family characteristics, employment status to identify their patterns and characteristics, and thus to provide the basis for the reasonable boot vocational differentiation of the farmers. © 2012 IEEE.

Terrestrial vegetation dynamics are closely influenced by both climate and by both climate and by land use and/or land cover change (LULCC) caused by human activities. Both can change over time in a monotonic way and it can be difficult to separate the effects of climate change from LULCC on vegetation. Here we attempt to attribute trends in the fractional green vegetation cover to climate variability and to human activity in Ejina Region, a hyper-arid landlocked region in northwest China. This region is dominated by extensive deserts with relatively small areas of irrigation located along the major water courses as is typical throughout much of Central Asia. Variations of fractional vegetation cover from 2000 to 2012 were determined using Moderate Resolution Imaging Spectroradiometer (MODIS) vegetation index data with 250 m spatial resolution over 16-day intervals. We found that the fractional vegetation cover in this hyper-arid region is very low but that the mean growing season vegetation cover has increased from 3.4 % in 2000 to 4.5 % in 2012. The largest contribution to the overall greening was due to changes in green vegetation cover of the extensive desert areas with a smaller contribution due to changes in the area of irrigated land. Comprehensive analysis with different precipitation data sources found that the greening of the desert was associated with increases in regional precipitation. We further report that the area of land irrigated each year can be predicted using the runoff gauged 1 year earlier. Taken together, water availability both from precipitation in the desert and runoff inflow for the irrigation agricultural lands can explain at least 52 % of the total variance in regional vegetation cover from 2000 to 2010. The results demonstrate that it is possible to separate the satellite-observed changes in green vegetation cover into components due to climate and human modifications. Such results inform management on the implications for water allocation between oases in the middle and lower reaches and for water management in the Ejina oasis. © Author(s) 2014.

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.

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.

This study measures the production efficiency of corn in Hebei Province, China, basing on an inputoriented DEA model with the assumption of Variable Return to Scale (VRS). In this framework, 2 outputs and 6 inputs are included, based on the agricultural product survey conducted by Price and Cost Inspection Bureau of Hebei in 2008. The 44 counties sampled are treated as the Decision Making Units (DMUs). The result shows that, 22 counties are fully efficient and in the status of constant returns to scale; in 7 counties, production efficiency can only be improved through adjusting the farming scales; in the rest 15 counties, production efficiency can be improved through either reducing the inputs or compressing the farming scales. Slack analysis of outputs shows that comparing with technical improvement, much more margin lies in the socio-economic optimization. Meanwhile, the liquid inputs are similar in the efficient and inefficient counties, with less slack and radial movements; large differences, slack and radial movements exist amongst inputs connecting with the construction of agricultural infrastructure. Furthermore, production efficiency in corn and wheat are compared with the adoption of Crosstabs Analysis. Finally, policy implications are put forward, concerning the adjustment of farming scales, marketing facilitation thus improve the added value, construction of irrigating infrastructure and agricultural mechanization.

From the melamine incident of Sanlu milk powder in 2008 to the illegal food additives incident of Bright Dairy in 2012, the food safety problems of milk have been plaguing the Chinese National diet. This paper analyzed consumer willingness to pay for food safety in Shanghai China through a case study of GAP certified milk. Shanghai consumers were selected for the survey, in which a contingent valuation was conducted. The study found that consumers were willing to pay for GAP certificated milk at an average price of 2.38 RMB/250 ml, 18.5% higher than the ordinary milk price. The results of the binary logistic regression model showed that the factors that affect consumers' willingness to pay include gender, income, the price of GAP certified milk and whether there were preschoolers in the household as statistically significant.
