宪政运行的成本结构

分析宪政运行的成本结构，对于宪法实施、宪政评价和宪政社会的构建都有重要的时代意义。宪政运行成本就是宪政运行过程中所产生和付出的代价和费用，具有交易费用的性质。宪政运行的成本结构包括立宪成本、行宪成本、守宪成本和违完成本等。     

基于加权群体AHP的企业资信评价方法

本文研究加权群体AHP方法及其在企件资信评价中的应用问题,建立了反映各专家或决策者优先权及各判断矩阵可信度的两种加权距离法,从主观和客观两方面切实有效地反映了各专家或决策者意见对最终评判结果的影响。企业资信评价是银行信贷风险管理的重要基础工作之一,各企业资信等级的正确评定取决于许多相关因素,需要各方面专家或决策者进行综合评判,合理的评判结果应反映各专家或决策者对各企业及信贷风险状况了解和认识的程度,同时应反映各专家或决策者对各企业评判所给出的判断矩阵的可信度,因此,本文建立以各专家或决策者优先权及各判断矩阵可信度为权系数的加权距离法,较好地解决了该问题。     

A Minimum Distance Estimation Approach to the Two-Sample Location-Scale Problem

As reported by Kalbfleisch and Prentice (1980), the generalized Wilcoxon test fails to detect a difference between the lifetime distributions of the male and female mice died from Thymic Leukemia. This failure is a result of the test's inability to detect a distributional difference when a location shift and a scale change exist simultaneously. In this article, we propose an estimator based on the minimization of an average distance between two independent quantile processes under a location-scale model. Large sample inference on the proposed estimator, with possible right-censorship, is discussed. The mouse leukemia data are used as an example for illustration purpose.     

议论的技巧--论证说

时下有关论证的说法很多 ,有过程论 ,层次论 ,方法论 ,结构论等 ,本文认为论证是技巧 ,是“统合技巧”。它统合了诸如句法、词法、语法、修辞法、逻辑法、章法等方法 ,构成篇章修辞方法 ,完成一篇议论文的表达。

金融危机10年来中国股市动态演化与市场稳健研究——一个基于复杂网络视角的实证

将复杂网络理论最小生成树（MST）算法和滑窗分析相结合，在2008年全球金融危机和2015年中国股市震荡的背景下，以2003年至2017年的上证A股收益率数据作为实证样本，构建股票市场动态关联网络，并从网络节点移除和连边变化两个角度出发，对其在不同时期的动态演化特征和市场稳健性质进行探讨。研究结果表明：网络结构整体上在金融危机之前和之后较为松散，而在金融危机和股市震荡期间则变得非常紧凑，节点的度分布和影响强度分布更加聚集。这意味着在金融危机和股市震荡期间，系统重要性公司的影响力持续增强，其股价的变化对其它公司将产生更为显著的影响；不同类型的事件对股市网络连通性和稳健性的影响程度不同，区域性事件（股市震荡）比全球性事件（金融危机）对市场的冲击更大；短期来看，金融危机和股市震荡对网络连边的稳健性并没有造成太大的冲击，整个研究时段网络的存活比率都维持在较高的水平。但随着步长的增加，网络的存活比率急剧下降，这意味着股市网络相关结构的长期稳健性是减弱的。     

Online coupon consumption problem

Nowadays, it is popular that the dealer makes profits by selling a kind of discount coupons, which can be used as money to purchase commodities with total cost less than or equal to the face value of the coupon. We can purchase a coupon at a price of 0<s≤1 times its face value and the number of potential purchasable coupons is a given integer l. The customer has the option to buy the goods by cash completely or by a discount coupon. However, each piece of goods can only use one coupon and the coupon used must have enough balance for the goods. The objective is to minimize the total cost for purchasing all the goods. In this paper, we reduce the problem to a special bin packing model. We consider the online problems for all 0<s≤1 and 1≤l≤∞. We present optimal online algorithms for all 0<s≤1 when l=∞ and l=1. For 2≤l<∞, we give both a lower bound and an algorithm, and show the algorithm is optimal for l=2. A preliminary version of this paper appeared in the proceedings of the 1st International Symposium on Combinatorics, Algorithms, Probabilistic and Experimental Methodologies, Lecture Notes in Computer Science.

Contested news values and media performance during the Umbrella Movement

Social crises are a huge challenge to the performance of the media. The norms and routines of news making with which journalists comply can become problematic in the context of intensive public sentiment and empathy. News values, including the sacred belief in objective reporting, are questioned in the light of controversies over editorial judgment within and outside the newsroom. I examine the contested news values that manifested in the Umbrella Movement of Hong Kong in 2014. In particular, I focus on the arguments and deliberations regarding news objectivity, which involved several parameters of the performance of the media during this social crisis.     

印度对华化工产品反倾销的贸易效应分析

随着印度对华化工产品反倾销的频发,其所产生的贸易效应越发值得关注。通过构建半对数线性回归方程,以10位编码的化工行业涉案产品的月度数据作为基础进行实证检验,考察不同阶段贸易破坏效应和贸易转移效应的存在性及其大小,指出印度对华化工产品采取反倾销措施不仅会对我国产生负的贸易破坏效应,同时会引起竞争国对印出口增加,存在正的贸易转移效应。然而对于不同产品,破坏效应出现的时间和大小是有区别的,贸易转移效应则并非普遍存在。     

2020年:我国经济转型升级大趋势

2020年是我国经济转型升级的重要关节点.适应经济转型升级大趋势,推进由工业大国向服务业大国的转型,意味着经济的结构性升级.这不仅是一个经济增长新常态的形成过程,还伴随着经济结构新常态、利益结构新常态、制度创新新常态的形成;这不仅涉及经济领域的改革,还涉及社会、文化、生态等领域的改革;这不仅需要政府发展理念的变革,还需要政府角色的转换.推进服务业主导的转型与改革,将成为“十三五”时期提质增效、转型创新的主要推动力.
