摘要：Landscape design for a green community should be favorable for the ambient ecological environment and for enhancement of both the local climate of a residential area and the environmental quality of life. This paper presents optimization methods for plant landscape design that take account of results of comparisons of noise reduction effects, heat island temperature decreases and effects on ventilation. These methods are based on different plant configurations and various luminous environments, such as exterior sunshine and shaded areas after the simulation of exterior luminous, acoustic and thermal environments of a residential area using the analytic software ECOTECT, CADNA/A, and PHEONICS. Three different types of residential buildings are simulated including a faculty apartment in the Xixi Campus of Zhejiang University, the Huaqing Villa and the Gangwan Jiayuan faculty apartment of Zhejiang University, China, based on green building design theory. In addition, the methods and process flow of landscape design of green residential areas are also described for the improvement of the exterior physical living environment.

摘要：艺术管理机制是艺术管理研究的核心领域,也是影响我国艺术管理改革的关键点。我国的艺术管理在发展过程中受西方艺术管理观念的影响较大,这种西化的管理方式虽对中国艺术管理体制的改革具有一定的启发作用,但在全球艺术市场竞争日趋激烈的背景下,其暴露出来的弊端也愈来愈明显。在跨文化交流中,我们应立足本国国情,构建具有本土特色的管理方式和话语体系,形成艺术管理的中国机制。基于霍夫斯泰德的国家文化模型,艺术管理的中国机制需从管理原则、管理风格、管理方向、管理者、管理方法及管理的人文情怀上进行立体架构,以此促进我国艺术管理机制的特色化发展。

摘要：将延迟决策引入到双寡头有限理性广告博弈模型中,研究了其对系统的影响,并对该模型进行了稳定性分析.在此基础上,以累计利润为指标,通过数值模拟与仿真发现延迟变量的引入并不一定能够为企业带来竞争优势,而这主要取决于引入延迟变量的时间点和延迟变量系数的大小.同时对延迟变量系数与系统参数的稳定域之间的关系做了探讨,指出在混沌时如果延迟变量系数取得适当,将会极大地提高自身的竞争优势和系统的稳定性.另外,对混沌时降低单位广告所产生的平均需求的两种方式对企业的不同影响做了研究,并指出通过降低广告制作成本来降低单位广告所产生的平均需求将会为企业赢得更大的竞争优势.
