造假行为的传播与遏制——基于进化博弈模拟的研究

借鉴进化博弈的思想,一个新的模型建立起来用以模拟造假行为的传播过程,以期找到其广泛传播的路径,并寻找遏制的方法。模型赋予了个体学习的能力,结果显示惩罚程度对造假行为的传播没有影响,但抽查概率却是决定性的。为了提高查处的效率,"连带检查"机制被加入到模型中,即对造假者周围邻居进行检查并施以同样的惩罚。这种机制能够在抽取概率为26%时达到消除造假者的目的,相比之下,没有"连带检查"时必须把抽取概率提高到80%才能达到消除造假者的目的。     

Hazard rate ordering of the second-order statistics from multiple-outlier PHR samples

In this paper, we compare the hazard rate functions of the second-order statistics arising from two sets of independent multiple-outlier proportional hazard rates (PHR) samples. It is proved that the submajorization order between the sample size vectors together with the supermajorization order between the hazard rate vectors imply the hazard rate ordering between the corresponding second-order statistics from multiple-outlier PHR random variables. The results established here provide theoretical guidance both for the winner's price for the bid in the second-price reverse auction in auction theory and fail-safe system design in reliability. Some numerical examples are also provided for illustration.     

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。     

美国中小企业技术创新计划管理实践及启示——以TIP为例

美国技术创新计划(TIP)支持有科技优势的中小企业进行目标明确的变革性技术研发,以促进中小企业的技术创新和提升美国的竞争力。它的资助与管理具有支持企业面向国家需求的变革性研究、设立专门的咨询委员会、坚持以同行评议进行项目遴选等基本特点,以及具有把扁平化的组织管理与"跨办公室"工作模式相结合、"自上而下"与"自下而上"相结合、实行全过程管理与结果管理相结合等工作机制。它为我国科技计划管理改革带来的重要启示在于要面向国家产业需求,支持和引导中小企业的变革性技术研究;倡建中小企业创新联盟,鼓励高校、科研院所为中小企业服务;加强后评估研究工作,重视影响评估对科技计划管理的作用。     

Improved upper bound for the degenerate and star chromatic numbers of graphs

Let \(G=G(V,E)\) be a graph. A proper coloring of G is a function \(f:V\rightarrow N\) such that \(f(x)\ne f(y)\) for every edge \(xy\in E\). A proper coloring of a graph G such that for every \(k\ge 1\), the union of any k color classes induces a \((k-1)\)-degenerate subgraph is called a degenerate coloring; a proper coloring of a graph with no two-colored \(P_{4}\) is called a star coloring. If a coloring is both degenerate and star, then we call it a degenerate star coloring of graph. The corresponding chromatic number is denoted as \(\chi _{sd}(G)\). In this paper, we employ entropy compression method to obtain a new upper bound \(\chi _{sd}(G)\le \lceil \frac{19}{6}\Delta ^{\frac{3}{2}}+5\Delta \rceil \) for general graph G.     

基于分权视角的城市规划管理体制模式及改革建议

关于我国的城市规划管理权限一直存在＂集中＂与＂放权＂的讨论,并且城市规划管理体制也存在差异。通过对全国部分城市的规划管理体制进行梳理,从市、区（县、市）两级分权视角总结出我国城市规划管理体制中的＂垂直型＂、＂半垂直型＂和＂非垂直型＂三种典型模式,分别以南京、北京和上海为案例分析三种规划管理体制典型模式的主要特点和事权划分,并对其各自的优缺点进行比较,最后提出我国城市规划管理体制改革的若干建议,包括将规划决策权＂上收＂与实施管理重心＂下移＂、建立＂市—区—镇（街）＂三级规划管理机构体系、整合市区两级规划部门内部机构设置形成＂大处室＂和＂大科室＂以及完善城市规划委员会制度等。     

Global Governance and State Governance: Two Strategic Considerations in Contemporary China

Governance is a kind of holistic governance and the notion of governing holistically should be established. The holisticity of governance is reflected in the unity and coordination between value rationality and instrumental rationality, normative appeal and practical appeal as well as global governance and state governance. Global and state governances are two strategic considerations in contemporary China. Actively participating in global governance and rationally promoting state governance is the rational choice of contemporary China, which plays a unique and significant role in realizing the social transformation and national rejuvenation and modernization of contemporary China. Deepening state governance with the help of global governance and promoting global governance with the support of state governance is the basic idea and dimension of understanding and grasping the interaction, coordination and overall planning between the two. The restrictions and effects of global governance on state governance are mainly reflected in such considerations as objects, mechanisms, concepts and interests of governance, and modernization of state governance system and improvement of governance capacity can promote and deepen global governance in a more effective way.     

Stereotype and National Attachment in Hong Kong Chinese Context: A Moderated Mediation Model of Perceived Inter-group Relationship and Age

The present study investigated the relationship between Hong Kong people’s stereotype toward Mainland people and their own national attachment (i.e., national identity, constructive patriotism, and uncritical patriotism). The role of inter-group relationship as mediator and age as moderator of that relationship were also tested. A total of 1753 local Hong Kong people aged 17–80 (mean age = 20.35 years, SD = 5.02) completed anonymous questionnaires regarding their stereotypes toward Mainland people, inter-group relationship with Mainland people, and national attachment. As expected, stereotypes toward Mainland people, inter-group relationship and national attachment showed significant positive associations with each other. More interestingly, it was found that the inter-group relationship mediated the relationship between stereotypes toward Mainland people and three domains of national attachment, with this indirect link being weaker for younger Hong Kong adults than for older Hong Kong adults. Implications of the present findings for future research are discussed, as well as potential interventions for increasing subjective national attachment to China, especially in young Hong Kong people.
