Industrial Knowledge Bases as Drivers of Open Innovation?

The article presents an analysis of a large-scale survey with the aim of understanding differences in the open, interactive and distributed nature of external innovation relations amongst firms belonging to different industrial knowledge bases. The thesis is that the source of critical innovation relevant knowledge differs between industrial knowledge bases, making the character and the need of openness contingent on these specificities. Accordingly, we anticipate that we will observe systematic variations in how industries access and combine innovation-related external knowledge. In our analyses we attempt to address a gap in the literature by examining how industrial knowledge bases affect the recombination of knowledge by analysing the different extents, forms (formal and informal) and geography of inbound open innovation. The article illustrates that features and structures of inbound open innovation align, to a large extent, with the industries' knowledge bases and that there is a interplay between an industry's knowledge base, the internal organisation of innovation processes and the channels and geography of inbound open innovation.     

我国素质教育模式下的中小学校园空间设计浅析

相对于过去的应试教育,素质教育是依据人的发展和社会发展的实际需要而产生的。总体而言,目前我国中小学校园规划、建筑设计理念、设计标准是与传统教育的以“教师为中心”、“编班授课”特征相匹配的,不能完全满足素质教育的要求。要创造适合素质教育的校园环境,就必须探讨素质教育对中小学校园外部及内部空间设计过程中的促进与影响。     

科研机构向公众开放活动中的问题研究——以中科院为例

Eye-tracking Analysis in Landscape Perception Research: Influence of Photograph Properties and Landscape Characteristics

Abstract

The European Landscape Convention emphasises the need for public participation in landscape planning and management. This demands understanding of how people perceive and observe landscapes. This can objectively be measured using eye tracking, a system recording eye movements and fixations while observing images. In this study, 23 participants were asked to observe 90 landscape photographs, representing 18 landscape character types in Flanders (Belgium) differing in degree of openness and heterogeneity. For each landscape, five types of photographs were shown, varying in view angle. This experiment design allowed testing the effect of the landscape characteristics and photograph types on the observation pattern, measured by Eye-tracking Metrics (ETM). The results show that panoramic and detail photographs are observed differently than the other types. The degree of openness and heterogeneity also seems to exert a significant influence on the observation of the landscape.
