屋面工程施工中基层质量的管理

要在屋面工程施工中保证基层质量防止屋面渗漏,必须让操作人员了解工程的技术要求,提高操作技术水平和质量意识并严把建材质量关,从而保证施工中的各关键环节（屋面板安装、灌板缝、板端头缝、找坡层、保温层、节点和细部处理、找平层、防水层等）的精心施工、认真养护和整体质量。     

我国发展清洁能源的驱动机制研究

大力发展清洁能源是实现低碳经济的主要途径,也是我国的基本国策。现阶段,我国清洁能源发展虽已取得一定成绩,但仍存在生产成本高、融资难、市场拉动力不足等障碍因素。为此,基于清洁能源发展相关利益主体的视角,构建了由政府扶持、利益诱导和需求拉动等我国清洁能源发展的内在驱动机制。

中国企业全球攻略:“三位一体”廓清贸易障碍

当今形势下,全球化战略成为中国企业的必然选择。中国企业应从战略高度上,以全球为市场、以学习为手段,来积蓄国际化经营的知识经验和管理技能,培育能带来持久竞争优势的战略资源与核心能力,构筑全新的竞争优势。但金融危机爆发以来,国际贸易保护主义重新抬头,各国因自身利益而产生的贸易摩擦越来越多。作为世界贸易大国,受国际国内双重因素影响,我国也面临着国际贸易摩擦的高发期,贸易摩擦日益成为阻碍我国企业全球化战略发展的消极因素。为有效破解国际贸易壁垒,妥善处理贸易摩擦问题,推动国内企业向国际型企业成功转变,必须从国家、行业、企业三个层面入手化解国际贸易摩擦。     

后危机时代绿色壁垒对河南省农产品出口的影响及对策

后危机时代绿色壁垒贸易保护主义又有新发展,表现在其实施范围扩大、实施形式增多、实施国增多和实施更加严格。河南省是农业大省,但农产品出口总量较低,出口产品以低附加值的初级产品和半成品为主,绿色贸易壁垒对其农产品出口带来严重不利影响,主要表现在缩减出口范围,减缓出口增速,影响出口市场的巩固与扩大,不利于开拓新兴市场等方面。为此,需要从政府与企业两个层面采取有效措施构建应对绿色贸易壁垒的政策体系。     

国际贸易中的动物福利问题研究及我国的对策

动物福利的出现,一方面是经济发展和社会进步的表现;另一方面,是由于发达国家和发展中国家之间存在着巨大的差异。文章对动物福利和动物福利壁垒内涵作深入的剖析,从市场准入限制、产业竞争力影响和贸易抑制影响等方面分析了动物福利壁垒所产生的经济效应;指出动物福利壁垒对我国出口贸易的影响越来越明显。因此,正确认识动物福利问题、增强动物福利意识、加强动物福利立法、建立预警机制、改革农牧业的生产方式、加大投入和依法抵制新贸易保护主义是我国应对动物福利壁垒的主要策略和措施。

New Evidence of Psychological Barrier from the Oil Market

The authors examine how stock returns were affected when the oil price reached the psychological barrier of US$100 per barrel for the first time in history. Using an event study approach, 4 key results emerge. First, the authors show that a psychological barrier event in the oil market does affect stock returns. Second, they show that a psychological barrier event in the oil market is a source of return drift—a phenomenon well explained and understood with respect to nonoil news events. Third, the psychological barrier affects small/medium-sized stocks and not large stocks. Last, the authors show that successful trading strategies can be devised based on the information that the oil price psychological barrier significantly impacts the market and that it contributes to return drift.     

Optimal dividend policies for piecewise-deterministic compound Poisson risk models

This paper considers the optimal dividend payment problem in piecewise-deterministic compound Poisson risk models. The objective is to maximize the expected discounted dividend payout up to the time of ruin. We provide a comparative study in this general framework of both restricted and unrestricted payment schemes, which were only previously treated separately in certain special cases of risk models in the literature. In the case of restricted payment scheme, the value function is shown to be a classical solution of the corresponding HJB equation, which in turn leads to an optimal restricted payment policy known as the threshold strategy. In the case of unrestricted payment scheme, by solving the associated integro-differential quasi-variational inequality, we obtain the value function as well as an optimal unrestricted dividend payment scheme known as the barrier strategy. When claim sizes are exponentially distributed, we provide easily verifiable conditions under which the threshold and barrier strategies are optimal restricted and unrestricted dividend payment policies, respectively. The main results are illustrated with several examples, including a new example concerning regressive growth rates.
