Contribution to the Investigation of Structure and Origin of the East African Graben by Gravimetry

IntroductionGeophysics as its nameindicates has to do withthe physics of the earth and its surrounding at-mosphere . Gilbert’s discovery that the earth be-haves as a great and rather irregular magnet andNewton’s theory of gravitation may be said toconstitute the beginning of geophysics . Miningand the search of metals date from the earliestti mes , but the scientific record began with thepublicationin 1956 of the famous treatise De remetallica by Georgius Agricola , whichfor manyyears was …     

应急调水效益补偿的博弈分析

应用博弈论原理与方法求解应急调水的合理补偿量,解决调水各方的利益冲突.提出了水权交易、行政调节、流域协商3种补偿的方式,用博弈原理对这3种方式进行了分析,求解在纳什均衡条件下,利用水权交易方式和行政调节方式实现水资源配置目标的补偿量方案,并对流域协商方式的博弈特性进行了分析,并给出算例,分别解出两种补偿方式的补偿方案.不同的补偿方式对应着不同的补偿量,在实际应用中可根据应急调水的实际情况,选择一种方式或多种方式联合应用,为管理者的决策提供参考.

基于预报及库容补偿的水库汛限水位动态控制研究

结合清江流域梯级水电站工程特性及防洪任务,以不降低梯级防洪标准为原则,建立基于预报及上游水布垭水库库容补偿的汛限水位动态控制模型,推求隔河岩水库汛期汛限水位动态控制方案。计算表明,该模型在不降低水库及梯级原有的防洪标准前提下,能有效利用上游水布垭水库的防洪库容,分担隔河岩水库部分防洪任务,并显著提高其发电量。其中,多年平均弃水量减少4．1444亿m~3,发电量增加1．2172亿kW·h。     

城市规模与高管工资溢价区域差异分析

利用2008—2017年中国A股上市公司和地级市层面数据,采用回归模型进行实证分析并作检验后发现：① 高管薪酬显著地受相邻地区同行薪酬的正向影响,但更多地还是由公司情况及高管自身水平决定;② 城市规模和城市的集聚经济正相关,集聚经济对高技能劳动力的工资水平有促进作用,形成工资溢价,不同城市规模产生的集聚经济效应是产生工资溢价的主要原因;③ 不同规模城市等级对高管薪酬的影响呈现差异化特征,因为不同城市厂商的生产率水平不同,大城市能够为高技能劳动力提供更好的学习机会,表现为水平效应和增长效应;④ 房屋价格对工资有正向影响,人均绿地面积的提高及城市居住环境的改善,会使工资水平有所上升,但超大城市可能因其生活成本及房价过高等因素的影响对高管薪酬正向影响相对减弱。     

Impact of farmer households’ livelihood assets on their options of economic compensation patterns for cultivated land protection简

With rapid urbanization and the socio-economic transformation, cultivated land protection has gradually become a major concern in China. The economic compensation plays a crucial role in promoting cultivated land protection and improving the utilization ratio of cultivated land. Farmer household＇s satisfaction has a great influence on the effectiveness of compensation. Therefore, households＇ willingness to select the economic compensation pattern for cultivated land protection has been considered and re-examined. By employing Participatory Rural Appraisal method （PRA）, 3 villages and 392 households were investigated and sampled in mesa and hilly areas of Chongqing. Then a quantitative analysis framework of household livelihood hexagon has been developed to quantify the livelihood assets of differ- ent farmer households. Finally, the Gray Relation Model and Probit Regression Model have been employed to explore the coupling relationship between the household livelihood assets and their compensation pattern options. The results show that there are both qualitative and spatial heterogeneity in household livelihood assets. We found that the inequality of livelihood assets is evident for five household types. There is a spatial trend that the higher the eleva- tion, the less livelihood assets are. In addition, their options of economic compensation pat- tern vary from Chengdu Pattern to Foshan Pattern due to their difference in livelihood assets and difference in location. In detail, there is a coupling relationship between household live- lihood assets and their compensation pattern; negative correlation is observed between natural assets value and household pattern options, while the other livelihood assets have positive impacts on compensation pattern in varying degrees, which from the top are psy- chological assets, human assets, physical assets, financial assets, and social assets respec- tively. A conceptual compensation pattern system has been designed to meet the demands for farmer households mainly according to their shortage in livelihood assets. In addition, compensation method, compensation standard, the basis of compensation and the source of compensation funds have been proposed accordingly.
