The palm oil industry exemplifies the ‘regionalisation without regionalism’ pattern seen in other industries in Asia: extensive, regionally concentrated transnational economic integration accompanied by a low level of formal regional institution-building. Production is concentrated in Malaysia and Indonesia, and Asian countries account for a major share of the market for intermediate products. The ownership structure of palm oil production reflects the dominance of transnational Malaysian and Singaporean firms. There is no authoritative regional institution governing production, investment standards or labour in the industry. A patchwork of both enabling and regulatory governance institutions supports the industry. These are formal and informal, public and private, and are situated at multiple levels: within, below and across the nation state. Although the governance structure surrounding the palm oil industry has supported it well in terms of production volumes and profits, large externalities—environmental and social costs—persist. This article argues that the governance failures associated with the industry stem from different stakeholders' competing interests in contexts of highly unequal wealth and power distribution. Misgovernance is not an unintended consequence of institutions failing to keep up with markets in scale and scope, but is embedded in the multilevel governance regime that supports, and partially regulates, the industry.  相似文献

The Festival of Pacific Arts, hosted by a different Pacific Island state once every four years, is a prime site for the reproduction of the global discourse on heritage. Drawing on ethnographic research conducted at the festival, this paper focuses on how the concept of heritage is employed at the festival as both an instrument of statecraft and a tool for the assertion of grass-roots political and economic agency. We conclude that heritage in the context of the festival is a form of cultural practice involving relationships of power and inequality, expressed in transactions of ownership and value transformations that have become over determined by economic logic and the concept of property.  相似文献

This article examines the relationship between literary and bioarchaeological approaches to slavery, and investigates how the methods and priorities of each discipline might inform each other in understanding what it was like to be enslaved. Both bioarchaeologists and creative writers have attempted to access the inner lives of enslaved people, yet there has been little interaction between them. This paper offers an account of a research project which brought together a literary scholar, two archaeological scientists and seven creative writers to explore how writing might not only communicate a history understood through archaeological evidence, but could itself inform approaches to that evidence. We discuss two key themes which emerged from the project: Conversation and Caring. These themes were crucial to the interdisciplinary process, as it was only through attention to our relationships with each other that we could begin to reassess the nature of material in each of our disciplines.  相似文献

通过考察多元场对钧瓷文化创意产业知识创造、流动及学习创新的影响发现:①场为主体的地理、社会及文化认知等临近等提供了条件,有助于经验意会及符号知识的获得、共享与传播,有利于思想的交流碰撞及创意萌生;②生产现场、地方关系场、地方社会场与临时性场在钧瓷的学习创新中发挥着不同而又相互补充的作用。生产场推动着集群知识积累和增进,地方关系场促进了行业知识、生产经验及家族核心知识的传播传承,地方社会场形成了地方共享知识信息,而临时场建立起外部通道联系,发挥着更新地方知识库的作用;③地方性的历史文化资源与传统以及地理-社会-文化等临近造就了外围地区文化创意经济的动力,但若未来本地知识更新的机制不够强大,则易产生发展锁定,这是需要未来引起关注的问题。  相似文献

全球—地方关系为产业创新研究提供了新的视角。本文基于全球(通道)—本地(蜂鸣)关系视角构建了软件产业集群创新效应研究的理论框架。以西安市软件产业集群为例,采用Stata13定量分析不同尺度创新合作的创新效应及其影响因素。研究发现,本地和国际创新合作均对集群创新具有积极的影响,且后者比前者的创新效应更强,说明搭建外部通道对集群创新的必要性;本地与国际创新合作交互对不同规模的软件企业产生的创新效应不同,对小型软件企业存在减法效应,对中型软件企业存在加法效应,对大型软件企业具有乘法效应。建立领先软件企业带动的开放创新系统,是西安市软件产业集群提升创新效应的有效路径。  相似文献

The paper analyses the emergence of the Artificial Intelligence (AI) cluster in Montreal and investigates two questions: (1) What are the different theoretical interpretations related to the emergence of industrial cluster? And (2) What are the factors underlying the emergence of the AI cluster in Montreal and to what extent have local and global factors been decisive in this respect? The AI cluster emerges through a process that brings into play the interaction between the local initial conditions and the birth of a new industry. Moreover, it also involves an interaction between the local and the global, which is supported by interactions with foreign actors located in different parts of the world.  相似文献

Science Cities: What the Concept of the Creative City Means for Knowledge Production. – The article aims to show that the relationship of science and the city has changed since the 1970s in the context of the knowledgeable society. While cities have principally been regarded as the typical space of science, of new ideas and innovation for centuries, since the 1960s and 1970s universities, research institutes as well as industrial research institutes have relocated to the periphery of cities. There, however, these sites of knowledge have been organized in an ‘urban mode’. That means that the concept of the city as a place of science and innovation has determined the architectural, spatial, and social organization of these sites on the periphery of cities. Certain features of the city have been copied, such as social infrastructures, places of communication, restaurants, cafes etc., while others have been left out – housing, cinema, theatre etc. An ‘urban mode of knowledge production’ in the sense of a very stylized model of the city has become a tool to enhance the production of scientific and technological knowledge. – The article exemplifies this by focusing on a case study, namely of the so‐called ‘Science City’ of the Siemens Company in Munich‐Neuperlach.  相似文献

20世纪90年代中期以来,中国出版业经历着从计划经济向社会主义市场经济转变的历史性进程。从1993年开始到1998年,出版业改革的主线是由“规模数量为主要特征向以优质高效为主要特征”的“阶段性转移”;从1998年开始到2002年,集团化发展成为出版业改革的主题;从2003年开始,企业化转制成为出版业改革与发展的方向和主线。十多年来,出版业的政策走向反映了中共中央、国务院对出版工作的高度重视和大力支持,反映了出版业逐渐加快了产业化、市场化、国际化进程,反映了出版业改革不断深化的脉络。  相似文献

A new classification system is proposed to describe the volumetric formats of clastic lithic products of geological and archaeological origin. In order to build this operative classification, the rectangular block or cuboid is established as the standard geometric format to represent their three‐dimensional format (the X‐axis being length or long diameter, the Y‐axis being the width or intermediate diameter, and the Z‐axis being the thickness or short diameter) on a two‐dimensional diagram. To obtain this graph, each absolute coordinate (X, Y, Z) defining the prisms is projected on to an auxiliary plane with a new set of relative coordinates (x, y, z), expressed as the percentage of their sum. The projection generates a triangular diagram on which the indices of elongation and flatness are represented. A geometric transformation converting the triangular diagram into a quadrangular diagram has been produced in order to better represent the scatter points. Then, a double scale is necessary: (i) an absolute scale to quantify the indices, and (ii) a relative scale to calculate where the graphic locus is projected. This new graph also allows us to work with statistical parameters. Finally, two classic examples of applications selected from the literature are shown.  相似文献
