| 6 | Irrigation Water Use Efficiency of Farmers and Its Determinants: Evidence from a Survey in Northwestern China显示文摘Irrigation water shortage is becoming an increasingly serious problem in agricultural production. In this case, it is very important for policy makers to take measures to improve irrigation water use efficiency, especially in the water-scarce areas. In this paper, the data envelopment analysis (DEA) techniques, based on the concept of input-specific technical efficiency were used to develop farm-level technical efficiency measures and sub-vector efficiencies for irrigation water use. The Tobit regression technique was then adopted to identify the factors that influence irrigation water efficiency differentials under the shortage of water resources. Based on a sample data of 432 wheat farmers in northwestern China, our experimental results of the DEA analysis showed the average technical efficiency of 0.6151. It suggested that wheat farmers could increase their production by as much as 38.49% by using inputs more efficiently. Further, the mean irrigation water efficiency of 0.3065, suggested that wheat farmers could produce the same quantity of wheat using the same quantity of inputs but with 69.35% less water. The results of the Tobit regression analysis showed that the farmer’s age, income, education level, and the farm size tended to affect the degree of irrigation water efficiency positively, and the channel conditions and different irrigation methods made a significant impact on irrigation water use efficiency. Furthermore, the arrangements of exclusive water property rights and competitive water price mechanism have effectively encouraged the water saving behavior of farmers. These results are valuable for policy makers since it could help to guide policies towards high irrigation water use efficiency. | WANG Xue-yuan College of Economics, Zhejiang Gongshang University, Hangzhou 310018, P.R.China | 2010 | Agricultural Sciences in China2010，9，9： | 16 |

| 11 | A PRICE-SETTING NEWSVENDOR MODEL UNDER CVAR DECISION CRITERION WITH EMERGENCY PROCUREMENT显示文摘In this paper,we consider a newsvendor model in which a risk-averse manager faces a stochastic price-dependent demand in either an additive or a multiplicative form.An emergency purchase option is allowed after the realization of demand to satisfy the units that are short.By adopting conditional value-at-risk(CVaR) as the decision criterion,we aim to investigate the optimal pricing and ordering decisions,and the effects of parameter changes in such a setting.We provide sufficient conditions for the uniqueness of the optimal policy for both demand models.We perform comparative statics analysis to show how the optimal pricing and ordering decision behaves when changing parameters.We also compare our results with those of the newsvendor with a general utility function and with CVaR criterion under lost sales assumption.Our key results include:(i) For both demand models,the optimal selling price is decreasing in risk aversion.Hence,the optimal price of a risk-averse newsvendor is not greater than the optimal price of a risk-neutral newsvendor.(ii) In contrary to the lost sales case,for the multiplicative demand model,the optimal order quantity may not be monotonic in risk aversion. Consequently,the optimal risk-averse order quantity may be lower or higher than the optimal risk-neutral counterpart.(iii) For the additive model,the optimal order quantity is strictly increasing in the emergency purchase price,while for the multiplicative model the optimal order quantity has no such a monotonic property.Some numerical examples are conducted to verify our claims and gain more insights about the risk-averse decision-making behaviors. | Minghui XU School of Economics and Management,Wuhan University,Wuhan 430072,China | 2010 | Journal of Systems Science and Systems Engineering2010，19，1： | 12 |
| 12 | Valuing water quality in China:purpose,approach and policy显示文摘The economic valuation of water quality in a rapidly developing country such as China should be undertaken to determine when the benefits from rapid growth begin to exceed the costs from the same. The best approach is to ascertain the total economic valuation of the environmental resource. This includes all of the various uses of the resource, and even those values that are unconnected to individual use (e.g. natural and aesthetic values). A method known as contingent valuation (CV) is used to ascertain these forms of value. This approach is demonstrated here in an application to river water quality in the Beijing area. A CV study is reported in which Beijing area citizens reported an average willingness to pay about 1.3% of annual income in order to prevent further deterioration of river water quality. Aggregation over the representative population indicates that the perceived cost of further river quality deterioration is in the neighbourhood of USD 60 million. Such a measure provides some indication of the socially desired “stopping point”—— in the pursuit of economic growth at the expense of environmental quality. | Timothy Swanson,Brett Day,Susana Mourato Centre for Social and Economic Research on the Global Environment, Department of Economics, and School of Public Policy, University College London, Gower Street, London WC1E 6BT, United Kingdom | 1999 | Journal of Environmental Sciences1999，11，3： | 12 |
| 13 | The evolution of cooperation in asymmetric systems显示文摘Explaining the 'Tragedy of the Commons' of the evolution of cooperation remains one of the greatest problems for both biology and social science.Asymmetrical interaction,which is one of the most important characteristics of cooperative systems,has not been sufficiently considered in the existing models of the evolution of cooperation.Considering the inequality in the number and payoff between the cooperative actors and recipients in cooperation systems,discriminative density-dependent interference competition will occur in limited dispersal systems.Our model and simulation show that the local but not the global stability of a cooperative interaction can be maintained if the utilization of common resource remains unsaturated,which can be achieved by density-dependent restraint or competition among the cooperative actors.More intense density dependent interference competition among the cooperative actors and the ready availability of the common resource,with a higher intrinsic contribution ratio of a cooperative actor to the recipient,will increase the probability of cooperation.The cooperation between the recipient and the cooperative actors can be transformed into conflict and,it oscillates chaotically with variations of the affecting factors under different environmental or ecological conditions.The higher initial relatedness(i.e.similar to kin or reciprocity relatedness),which is equivalent to intrinsic contribution ratio of a cooperative actor to the recipient,can be selected for by penalizing less cooperative or cheating actors but rewarding cooperative individuals in asymmetric systems.The initial relatedness is a pivot but not the aim of evolution of cooperation.This explains well the direct conflict observed in almost all cooperative systems. | WANG RuiWu1 & SHI Lei2 1 State Key Laboratory of Genetic Resources and Evolution,Kunming Institute of Zoology,Chinese Academy of Science,Kunming 650223,China 2 Statistics and Mathematics College,Yunnan University of Finance and Economics,Kunming 650221,China | 2010 | Science China(Life Sciences)2010，53，1： | 11 |

| 15 | The endocrine regulation network of growth hormone synthesis and secretion in fish: Emphasis on the signal integration in somatotropes显示文摘In teleosts, growth hormone (GH) production is governed by multiple neuroendocrine factors from the hypothalamus and other regulators from the pituitary and peripheral organs. Exploring the principles followed by pituitary somatotropes when differentiating and integrating the signals from these regulators at the cellular and intracellular level is essential for understanding the endocrine regulation network of growth hormone synthesis and secretion in fish. This paper discusses recent advances in the action mechanisms of GH regulation factors, including the neuroendocrine regulators, pituitary level factors and peripheral factors, primarily involved in their receptor systems as well as in post-receptor signal transduction pathways. | LI WenSheng & LIN HaoRan State Key Laboratory of Biocontrol, Institute of Aquatic Economic Animals and the Guangdong Provincial Key Laboratory for Aquatic Economic Animals, School of Life Sciences, Sun Yat-sen University, Guangzhou 510275, China | 2010 | Science China(Life Sciences)2010，53，4： | 11 |
| 16 | Arsenic trioxide promotes mitochondrial DNA mutation and cell apoptosis in primary APL cells and NB4 cell lines显示文摘This study aimed to investigate the effects of arsenic trioxide(As2O3) on the mitochondrial DNA(mtDNA) of acute promyelocytic leukemia(APL) cells.The NB4 cell line was treated with 2.0 μmol/L As2O3 in vitro,and the primary APL cells were treated with 2.0 μmol/L As2O3 in vitro and 0.16 mg kg-1 d-1 As2O3 in vivo.The mitochondrial DNA of all the cells above was amplified by PCR,directly sequenced and analyzed by Sequence Navigatore and Factura software.The apoptosis rates were assayed by flow cytometry.Mitochondrial DNA mutation in the D-loop region was found in NB4 and APL cells before As2O3 use,but the mutation spots were remarkably increased after As2O3 treatment,which was positively correlated to the rates of cellular apoptosis,the correlation coefficient:rNB4-As2O3=0.973818,and rAPL-As2O3=0.934703.The mutation types include transition,transversion,codon insertion or deletion,and the mutation spots in all samples were not constant and regular.It is revealed that As2O3 aggravates mtDNA mutation in the D-loop region of acute promyelocytic leukemia cells both in vitro and in vivo.Mitochondrial DNA might be one of the targets of As2O3 in APL treatment. | MENG Ran1,ZHOU Jin2,SUI Meng3,LI ZhiYong4,FENG GuoSheng1 & YANG BaoFeng2 1 Division of Neurology,the Ninth Clinical Medical College of Beijing University(Shijitan Hospital),Beijing 100038,China 2 The First Hospital of Harbin Medical University,Harbin 150001,China 3 Management Information System,University of International Business and Economics,Beijing 100029,China 4 Department of Radiology,Cambridge University Hospitals NHS Foundation Trust Box 219 Level 5,Addenbrooke’s Hospital Cambridge CB2 0QQ,UK | 2010 | Science China(Life Sciences)2010，53，1： | 10 |
