From victims to winners: strategies of negotiation among relocated residents in demolition-compensation events in local China

It has been well documented by researchers that in China’s continual quest for modernisation and urbanisation, many urban and rural residents became displaced and portrayed as victims. A more important question however needs to be explored: do evicted residents learn from others to develop strategies to protect themselves from becoming victims? Through in-depth interviews, primary data collection, documentary research, this study has confirmed that for some evicted residents in Southern China’s urban fringes, when their land was appropriated by local government and developers and they were offered resettlement elsewhere, they did not behave passively to accept the terms of compensation dictated. Instead, they actively learnt from other dwellers who were evicted earlier to become well-organised, resourceful, and sophisticated negotiators in bargaining for their compensation. The group of rural residents proved that they could do better than the evicted urban residents, especially in terms of compensation-negotiation.     

基于需要层次理论的保险代理人分类激励机制指标体系设计

针对保险代理人的具体情况和实际需求，将马斯洛的需要层次理论灵活地应用到实际当中，设计出一系列量化分类指标，运用数理统计方法，进行加权汇总后得出几个总值，对这几个总值的大小进行排序，根据排序的结果科学理性地将保险代理人分成若干类别，在对保险代理人管理过程中可以针对不同类别的代理人采取不同激励措施，进而有效而又低成本地解决保险业对代理人激励不力的问题。     

中国明代白银货币政策与商品竞争力分析

16世纪中叶,由于新航路的开辟,世界市场形成,白银成为世界货币。中国由于是白银贫矿国,在明代之前一直实施铜铸币和纸币政策,只是在明代中叶之后对白银货币实施了放任的政策。由于中国人多地少,劳动力十分廉价,这样以白银为计价单位所表示的商品价格极为低廉。欧洲由于人均土地资源高于中国,人均薪资也高于中国,而且白银供应极为充沛,在一般日用品价格上,远远高于中国。因而,在一般商品价格竞争上,总体不敌中国。当时美洲和日本盛产白银,是世界白银的价格洼地,欧洲又实施了较为自由的贸易政策。这样控制白银的欧洲、日本和掌握世界最低廉商品的中国,相互之间都有极为旺盛的需求,于是,世界市场很快就形成了美洲、日本白银与中国商品交换的格局。     

十月革命与中国共产党的初心构建

十月革命是影响世界历史进程的重大事件，中国共产党从来都把自己的事业看作是十月革命的继续。澄清唯心史观和历史虚无主义对十月革命的错误解读，对于补好理想信念的精神之钙具有重要的理论价值和现实意义。学习和借鉴十月革命的宝贵经验、坚持社会主义的前进方向、坚守共产主义的远大理想，共同构成了中国共产党初心的核心意蕴。     

Partitioned log-rank tests for the overall homogeneity of hazard rate functions

In survival analysis, it is routine to test equality of two survival curves, which is often conducted by using the log-rank test. Although it is optimal under the proportional hazards assumption, the log-rank test is known to have little power when the survival or hazard functions cross. To test the overall homogeneity of hazard rate functions, we propose a group of partitioned log-rank tests. By partitioning the time axis and taking the supremum of the sum of two partitioned log-rank statistics over different partitioning points, the proposed test gains enormous power for cases with crossing hazards. On the other hand, when the hazards are indeed proportional, our test still maintains high power close to that of the optimal log-rank test. Extensive simulation studies are conducted to compare the proposed test with existing methods, and three real data examples are used to illustrate the commonality of crossing hazards and the advantages of the partitioned log-rank tests.     

水平井中砂泥岩互层的双侧向测井响应研究

摘要：针对砂泥岩互层的复杂测井环境，采用三维有限元数值模拟方法，计算了多层介质模型的水平井双侧向测井响应。结果表明，井眼半径、泥浆电阻率和围岩（砂岩、泥岩）的电阻率及侵入半径与电阻率对水平井双侧向测井响应都有不同程度的影响。在砂泥岩地层中，井眼尺寸越大，泥浆电阻率越高，对视电阻率的影响越严重；当目的层厚大于8 m 后，视电阻率受围岩（砂岩、泥岩）影响很小，基本上反映地层的真实电阻率，并且曲线变化规律大致相同，此时可近似为三层介质模型；对于低阻侵入，侵入越深，视电阻率越偏离真实地层电阻率。

公共资源交易领域利益冲突及防治

近年来随着政府采购范围和工程招投标领域的日益扩展,公共资源交易领域腐败现象频发,成为利益冲突易发多发的重点领域。在公共资源交易过程中公职人员自由裁量权滥觞、利益冲突防范机制缺失和委托—代理运行失灵引致利益冲突的发生,而利益冲突直接或间接产生诱发公职人员腐败、侵害公共部门公信力、激化社会矛盾等负面影响。通过健全公共资源交易领域制度体系、完善公共资源交易领域多元防范机制和厘清公共资源交易领域政府角色扮演等措施,才能实现该领域利益冲突问题的有效防治。

An omnibus lack of fit test in logistic regression with sparse data

The usefulness of logistic regression depends to a great extent on the correct specification of the relation between a binary response and characteristics of the unit on which the response is recoded. Currently used methods for testing for misspecification (lack of fit) of a proposed logistic regression model do not perform well when a data set contains almost as many distinct covariate vectors as experimental units, a condition referred to as sparsity. A new algorithm for grouping sparse data to create pseudo replicates and using them to test for lack of fit is developed. A simulation study illustrates settings in which the new test is superior to existing ones. Analysis of a dataset consisting of the ages of menarche of Warsaw girls is also used to compare the new and existing lack of fit tests.
