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

故宫乾隆花园符望阁一层明间南向宝座的栏杆罩镶嵌着一组精美绝伦貌如金纱窗的漆纱隔心。类似的隔扇装修不仅在故宫,甚至全国范围内也是独一无二的。符望阁保护修复过程中,发现漆纱隔心存在损毁严重、工艺失传、复制难度大等问题。为对该组漆纱进行研究,运用剖面显微分析、扫描电镜与能谱仪分析、显微红外光谱及多种色谱-质谱联用等实验室科技手段,明确了漆纱由内而外"织物纱芯-双面贴纸样-双面上漆贴金-双面纸样上施绘"四层基本结构关系,以及单侧14个亚层所用的无机、有机材料,为漆纱的保护和复制提供了科学依据。  相似文献

The underwater of Sydney Harbour has its own histories, visual and literary representations, and narrators, but its contributions to Australian culture are yet to be fully recognised. Among European narrators were dress-divers whose technologies enabled access to an otherwise alien, inhuman world. This article discusses early dress diving in Sydney Harbour, focusing on an account by the explorer, Frank Hurley (1885–1962), of diving at Shark Island in 1921. Hurley's account is compared to the experiences of the harbour's professional dress-divers. His departures from reality are read as a science-fictionalisation of Sydney's submarine realm influenced by Jules Verne (1828–1905).  相似文献

In light of recent reflexive ethnography based on frameworks of performativity, this work develops a phenomenological interpretation of my white, male, gaijin (foreign), English-speaking positionality inside Japan's private English conversation schools (eikaiwa). These eikaiwa are ubiquitous in modern urban areas. They are patronized predominantly by women who seek career enhancement, study and/or work abroad, and international romance. To understand the gendered participation patterns inside the eikaiwa I develop a phenomenological understanding of my positionality through a framework based on Occidentalism. This framework is grounded in the ideo-geographically specific notions of seken (surveillance) and akogare (desire). Akogare is instantiated and intensified inside eikaiwa by the performative aspects of staff, students and instructor practices in addition to eikaiwa texts and advertising and popular media discourses while seken, especially gender-normative seken, directed at women is minimized. This framework allows me to present a nuanced account of the interaction of my positionalities with those of the informants.  相似文献
