Cleantech has emerged in the last decade as a major new investment sector at the forefront of the green economy. It responds to the need for innovative technologies to combat the impact of global environmental, climate and resource trends. Focusing on the cleantech sector, this article explores the central importance of relationality within the financial domain of the green economy. The central aim of this article is to deepen understandings of the operation of cleantech investment by examining the decision‐making processes of cleantech actors, how these are influenced by (and influence) cleantech investment networks, and the relationships between these factors and the macro‐level drivers and discourses focused on the cleantech sector. A relational economic geography approach is used in conjunction with other frameworks (spanning the cultural, structural and actor‐network dimensions of cleantech investment) to investigate: how cleantech investors define the sector; the macro‐ and micro‐level drivers of cleantech investment; and how cleantech networks form and operate to create and disseminate cleantech discourses and to generate the mutual trust and information sharing needed to secure cleantech investments. In so doing, the article seeks to shed greater light on the micro‐level processes contributing to the creation and growth of cleantech investment markets as an essential catalyst and component of the green economy.  相似文献

During recent reinvestigations in the Great Cave of Niah in Borneo, the ‘Hell Trench’ sedimentary sequence seen by earlier excavators was re-exposed. Early excavations here yielded the earliest anatomically-modern human remains in island Southeast Asia. Calibrated radiocarbon dates, pollen, algal microfossils, palynofacies, granulometry and geochemistry of the ‘Hell Trench’ sequence provide information about environmental and vegetational changes, elements of geomorphic history and information about human activity. The ‘Hell’ sediments were laid down episodically in an ephemeral stream or pool. The pollen suggests cyclically changing vegetation with forest habitats alternating with more open environments; indicating that phases with both temperatures and precipitation reduced compared with the present. These events can be correlated with global climate change sequences to produce a provisional dating framework. During some forest phases, high counts of Justicia, a plant which today colonises recently burnt forest areas, point to fire in the landscape. This may be evidence for biomass burning by humans, presumably to maintain forest-edge habitats. There is evidence from palynofacies for fire on the cave floor in the ‘Hell’ area. Since the area sampled is beyond the limit of plant growth, this is evidence for human activity. The first such evidence is during an episode with significant grassland indicators, suggesting that people may have reached the site during a climatic phase characterised by relatively open habitats ∼50 ka. Thereafter, people were able to maintain a relatively consistent presence at Niah. The human use of the ‘Hell’ area seems to have intensified through time, probably because changes in the local hydrological regime made the area dryer and more suitable for human use.  相似文献

The diffusion literature is replete with examples of highly salient policies spreading across subnational governments. However, low-salience policies that do not benefit from a groundswell of public opinion also spread across jurisdictions in patterns that appear similar to those of other, more well-known policy ideas. This research is an investigation of the mechanisms that propagate low-salience policies. I analyze the adoption of the U.S. Green Building Council's (USGBC) Leadership in Energy Efficient Design standard across 119 U.S. cities from 2000 to 2008. The investigation indicates that a knowledge broker, in this case the USGBC, occupies critical roles in linking a low-salience policy to a broader set of widely held societal values, developing a common policy vocabulary, providing a base policy that jurisdictions may freely adapt, and creating a diffusion infrastructure by acting as a communication hub for existing and interested jurisdictions to discuss innovations and progress.  相似文献

西安城市居民绿色出行的群体参照影响与自我价值判断   总被引:1,自引:0,他引:1  
选择本土城市居民为研究对象,以参照群体影响为外界变量,以自我感知价值为内部判断变量,将二者关联绿色出行意愿,意欲明晰是外部群体影响还是自我价值判断最终主导了人们的绿色出行选择。研究结果显示:参照群体的两类影响(信息性影响与规范性影响)对居民绿色出行意愿有显著正向影响;功能性感知价值与社会性感知价值对居民绿色出行意愿有显著正向影响,而情感性感知价值对居民绿色出行意愿影响不显著;中介效应结果表明,绿色出行感知价值在参照群体影响与居民绿色出行意愿之间存在部分或完全中介过程。  相似文献

潮湿土遗址隔水防潮技术对比研究   总被引:3,自引:0,他引:3  
潮湿土遗址的破坏,很大程度上是受水的影响,目前国内几个潮湿土遗址经常使用的防水隔水措施主要有:挡水墙、隔水廊道、拱券法和抽水法。经过对几种方法进行总结评价,可看出拱券法是最有效的方法。  相似文献

王油坊类型龙山文化的南徙之旅呈现东西两途。西线去往宁镇地区,即禹会-牛头岗-江宁点将台和高淳朝墩头;东线前赴环太湖流域,即禹会-南荡,至江阴花山,再东去松江广福林。在其南徙的过程中,江淮是必经之道。江淮属于"廊道"地区,一方面,它的连通性给区域间文化交流带来便利;另一方面,这一开放的区域又易引来外域强势文化的干扰,导致本地文化受损。众多的能流、物质流、信息流,都以高密度、高流速和少停留的方式从此通过,从根本上决定了廊道地区相比于稳定的文化母区,不可能凝聚和沉淀起深厚的文化底蕴,导致江淮地区的社会进程出现断裂相。  相似文献
