基于SCP范式对我国财产保险业的发展现状分析

中国自1980年恢复财产保险业务以来,财产保险业得到了快速发展。通过利用\"市场结构——市场行为——市场绩效\"理论分析财产保险业的发展状况,了解财产保险业发展过程中的内在矛盾,对今后财产保险业的快速发展有着重要的意义.     

非物质文化遗产的知识产权保护模式探析

非物质文化遗产是智力成果的范畴,应当属于知识产权保护的范围。而现有的知识产权制度无法发挥切实的保护作用。因此,要完善知识产权制度中的保护模式,才能使非物质文化遗产得到有效保护,使我国在这一领域中处于领先的地位。     

从《中华人民共和国物权法(草案)》谈城乡规划及其管理观念的转变

城乡规划代表公共利益,物权法保护物权人的合法权益;城乡规划及其管理代表一种调整和规范土地及地上建筑物等不动产物权的设立、行使的公共行政权力,物权法赋予了物权人对其不动产相关物权享有直接支配、排他性干涉的权力;在城乡规划及其管理工作方面,如何平衡上述两种权力?本文从城乡规划及其管理的主要环节--编制、实施、监督检查、批后管理四方面做出了阐释.     

Variation diminishing property of densities of uniform generalized order statistics

Let f _*,r , r ≥ 1, denote the density function of rth uniform generalized order statistics as defined by Kamps (1995) or Cramer and Kamps (2003). We prove the following variation diminishing property: the number of zeros in (0,1) of any linear combination does not exceed the number of sign changes in the sequence (a ₁, . . . ,a _r ). This result is applied to study monotonicity and convexity properties of f _*,r .     

独立审计质量的经济学分析

本文通过对审计质量的经济学分析,提出高质量的审计是增进契约效率的内生需要,中小股东和上市公司之间的“隐性契约”是推动审计质量提高的重要力量。我国特有的经济环境背景,决定了审计质量的提高存在着制度性障碍,审计质量是各方利益相互均衡的结果。     

国防知识产权与国防科技奖励的关联演化机理研究

本文通过详细阐述国防知识产权与国防科技奖励关联演化趋势,关联演化特征进行了深度的剖析。国防科技奖励与国防知识产权对于促进国防科技成果的产生、提高国防科技创新能力均具有重要的作用。最后结果表明,二者之间存在相互促进的关联演化关系,呈现出一种螺旋式的关联演化趋势。     

我国物业税开征的必要性及难点应对策略

"物业税"一词最早在我国被正式提出是在中国共产党十六届三中全会上通过的《中共中央关于完市场经济体制若干问题的决定》之中。该文件明确提出了:"实施城镇化建设税费改革,条件具备时对不动产开征统一规范的物业税,相应取消有关收费"。目前,世界上大多数成熟的市场经济国家都对房地产征收物业税,并以财产的持有作为课税前提、以财产的价值为计税依据,而在我国,物业税仍主要停留于理论层面,只在几个试点城市空转运行,关于物业税开征的利弊争论一直存在,是否开征物业税以及如何征收都是尚待解决的难题。     

A genetic algorithm based approach to transactional and QoS-aware service selection

As there are various risks of failure when Web services are deployed in unreliable environment, the execution of a composite Web service (CWS) requires the transaction mechanism to guarantee its reliable execution. However, the existing service selection approaches consider QoS and transaction separately and have not considered that transactional properties may affect the QoS such as the execution time of a CWS. This work addresses the importance of considering transactional properties and how the transactional properties affect the QoS simultaneously in the process of service selection by a QoS-aware and transactional-aware selection approach. First, a performance evaluation method is proposed to calculate the execution time of a transactional CWS. Then, a genetic algorithm based approach, which takes into account the execution time, price, transactional property and successful execution rate of CWS, is presented to achieve global optimisation service selection. Finally, experimental results show the efficiency and effectiveness of the approach.
