科技信息时代下构建我国水权交易制度推进水资源信息化管理

当前,我国水资源管理基础设施薄弱,监控手段缺乏,远不能满足水资源管理工作的需要,必须以各级水资源管理系统建设为抓手,全面推进水资源信息化,提高水资源管理能力与水平,落实最严格的水资源管理制度。为提高水资源利用效率、实现水资源经济价值,建立水权交易体系尤为必要。水权交易制度是以市场对水资源的使用权进行配置的制度,建立健全水权交易制度是实现水资源高效和持续利用的最佳途径。鉴于我国目前的水权制度的不足之处,建立水权交易制度应当遵循环境保护和可持续发展原则、宏观调控与市场调节相结合原则、平等自愿等原则。     

New results for path-based shared protection and link-based Hamiltonian cycle protection in survivable WDM networks

In this paper, we study the path-based shared protection (PBSP) and the link-based Hamiltonian cycle protection (LBHCP) schemes for tolerating single-link failures in survivable wavelength-division-multiplexing networks. Although previous work indicated that PBSP can perform better than link-based shared protection including the case of LBHCP, from theoretical analysis and simulation results in this paper, we can clearly see that this indication of previous work is not suitable for LBHCP since it can have a better resource utilization ratio and a faster recovery time than PBSP. Therefore, the new result of this paper is a modification for the previous inaccurate idea and it also can well guide future work of researchers.

Internal preference mapping and the issue of satiety

Internal preference mapping (IPM) and Landscape Segmentation Analysis® (LSA) are two techniques broadly used to unfold consumers’ overall product liking ratings and create spatial maps that will provide further insights on consumers’ preferences. IPM is based on a vector model while LSA involves an ideal point model. Through a simulation and the analysis of 27 market research data sets, it is shown that IPM consistently creates a hedonic dimension that prevents the identification of satiety prone attributes (intensities higher or lower than a optimal level being disliked by the consumers) on that dimension. As a result, subsequent steps taken upon generating an IPM map such as the investigation of drivers of liking, population segmentation and the estimation of optimal product profiles have also a strong likelihood of resulting in distorted results, the level of distortion being dependent on the actual configuration of the underlying structure that IPM tried to uncover. It is also shown that a technique based on ideal points such as LSA does not exhibit this systematic artifact when unfolding liking data. Consequently, sensory scientists and market researchers should use caution when interpreting and using results issued from an internal preference mapping analysis.

历史公共园林的价值探讨——以北京内城最大的水系公共园林什刹海地区为例

公共园林在中国古典园林体系中占有重要的地位。随着城市化进程的加快,大型公共园林与城市公共空间和社会生活的联系也越来越紧密。什刹海地区是北京城中轴线上典型的城市公共空间,是首都居民最为喜爱的公共游览区。同时,这里也是北京内城最大的一处水系公共园林,以什刹海为例,从生态、审美、文化和社会等方面来思考历史公共园林的价值,将对今后城市公共空间建设、生态文明建设以及和谐社会的构建具有启发意义。
