招投标活动公开、公平、公正原则探析

招投标活动在我国正式推行近二十年来 ,仍存在许多众人皆知的违背公开、公平、公正原则的现象 ,发人深省。本文在分析公开、公平、公正的内涵之后 ,指出应围绕程序公开与公平、人际公平与公正、结果公平与公正 ,以及实施有效监督这四个方面 ,探求确保招投标活动真正遵循公开、公平、公正原则的对策

重塑城市公园开放性——“开放街区化”的理念和启示

研究公园开放的内涵区别于管理开放的研究视角,依据城市空间密度变化和市民步行需求变化,从城市步行空间视角,反思通过管理手段开放的收费公园在空间状态上并未真正开放的现实问题,问题的出现在于收费管理模式引致的空间模式滞后。以公园城市为理念指导、开放街区化为技术路径,鉴别城市中心公园在城市步行网络中现有状态与应承角色之间的差异。多尺度比较传统公园模式与"开放街区"尺度的不协调性,理清传统公园空间模式向开放公园空间模式的转变途径,提出以外部城市空间步行肌理重塑内部公园交通,构建公园空间开放度评价体系(PSOA法)量化开放程度,以期定量描述空间的开放状态,改善并解决空间的开放问题,更好地应对城市中心地区的空间变化需求,服务城市步行体系,实现以人为本的公园空间和管理的双重开放。

A spectral directional reflectance model of row crops

A computationally efficient reflectance model for row planted canopies is developed in this paper through separating the contributions of incident direct and diffuse radiation scattered by row canopies. The row model allows calculating the reflectance spectrum in any given direction for the optical spectral region. The performance of the model is evaluated through comparisons with field measurements of winter wheat as well as with an established 3D computer simulation model. Especially the systematic comparisons with the computer simulation model demonstrate that the model can adequately simulate the characteristic distribution of directional reflectance factors of row canopies, which is shown in the polar map of reflectance as a high or low value stripe approximately parallel to the row orientation, besides the hotspot effect. Physical mechanisms causing the dynamics were proposed and supported by comparison studies. The features of reflectance distributions of row canopies, which are distinctively different from those of homogeneous canopy, imply that it is problematic to use one-dimensional radiation transfer model to interpret radiation data and estimate the structural or spectral parameters of row canopies from reflectance measurements. Finally, further improvements needed for the current model are briefly discussed.     

山地城市附属绿地开放适宜性评价研究

研究提出通过附属绿地开放来提升山地城市平坦开放性公共绿地数量与需求不均衡的困境。为提供一个科学的山地城市附属绿地开放适宜性评价方法,建立了由景观功能性、开放需求性和边界特性3个控制层及14个指标共同组成的评价指标体系,并采用AHP层次分析法和熵权法确定指标的权重。以承德市鹰手营子矿区中心城区居住用地、文化设施用地、教育科研用地和行政办公用地4类附属绿地作为研究对象,对其进行综合评价,根据分值计算发现,青少年宫、三合建筑公司等附属绿地为适宜开放的附属绿地,祥泰小区、左岸兰阁花园等附属绿地为较适宜开放的附属绿地,档案馆和区政府等附属绿地为不适宜开放的附属绿地。

Open strategy: Literature review,re-analysis of cases and conceptualisation as a practice

An increasing number of organisations (e.g., Daimler, IBM and Red Hat) have adopted what has been called “open strategy”: involving large groups of people in strategy making via information technology (IT). Our review of the recently emerged research stream on open strategy reveals inconsistencies in the use of explicit definitions and implicit conceptualisations of open strategy. To support future discourse and research, we develop a theoretically coherent and comprehensive conceptualisation of open strategy as a practice in this paper. This conceptualisation is based on a structured review of existing publications and re-analysis of well-documented open strategy cases. We use the strategy-as-practice lens and the concept of Idealtypus as theoretical foundations. The paper proposes a research agenda for open strategy.
