Mobilizing Artists: Green Patriot Posters,Visual Metaphors,and Climate Change Activism

This essay examines the Canary Project's Green Patriot Posters campaign as activist art that collectively comments on the cultural coherence of our current relations to the environment, particularly in terms of global warming, sustainability, and the concept of linear economic growth. Aspiring to bring together artists under the eco-activist umbrella, the Canary Project relies on an old WWII-inspired frame with a narrow premise of that period's conservation efforts. Within this framework, a range of visual designs question, subvert, and promote continued economic growth and an ontology that “more” equals “better.” An analysis of the up–down orientational metaphors underscores a typology of these valuations and reveals one way to assess implications of such artistic efforts. That is, artistic expressions adapt and play with the contingent nature of metaphors, offering elaborations, extensions, and alternatives on basic structural elements and, hence, remark on how we orient ourselves and productively imagine being of/in the world anew.     

中国低碳城市关注度研究

本文通过文献计量和社交大数据挖掘的方法统计到包含"低碳"和"城市"的文献共8 574篇,新浪微博51 081条。利用文献代表学者对于低碳城市的观点,利用新浪微博代表公众对于低碳城市的关注度,分别统计文献和新浪微博中城市出现频率以及关键词出现频率并进行分析。结果表明与低碳城市相关的文献和新浪微博从2010年开始增长,2013年达到峰值,2014年后略有回落。文献和新浪微博中出现频率最高的前30位城市基本一致,城市出现频率与城市行政地位和政策支持力度高度相关,另外文献和新浪微博中均未统计到的城市还有3个。词频统计结果表明:公众和学者对于低碳城市认知相差较大,学者更关注低碳城市建设和经济之间的关系,以及低碳城市对环境的影响程度。公众对于低碳城市的关注角度主要是从日常生活出发,更偏向于把低碳城市理解为低碳生活。建议政府进一步加大低碳城市的宣传力度,通过调整政策加大对非低碳试点城市和欠发达城市的扶持力度。并出台低碳城市的考核细则和评价标准,进一步理顺低碳发展与经济建设和环境保护的关系。     

环境库兹涅茨曲线理论与国家环境法律间关系的研究

研究表明,经济发展与环境退化之间经常呈现倒U型曲线关系,许多学者将其定义为环境库兹涅茨曲线(EnvironmentalKuznets Curves,EKC),并将其运用到对发展中国家和发达国家的先污染,后治理的发展模式的解释之中。但是环境库兹涅茨曲线假说本身并不完善。在摒弃了传统计量模型指标后,以国家环境立法和国家环保投资作为目标研究EKC。结果表明,环境改善的重要条件是政府的支持,尤其是以环境法律的形式。

Chemical Controversy: Canadian and US News Coverage of the Scientific Debate about Bisphenol A

This study analyzes how newspapers covered the scientific controversy surrounding the health effects of exposure to Bisphenol A (BPA). Specifically, it examines whether framing, sources of scientific information, and balancing of competing sides in the debate differed across national political contexts and journalistic approaches. In regard to the former, it compares coverage in Canada (represented by the Globe and Mail), which had banned BPA in baby bottles and cups, to coverage in the United States (represented by the New York Times and Washington Post), which had not. In regard to the latter, it compares coverage in two US newspapers that took a conventional journalistic approach (the New York Times and Washington Post) to coverage in a US newspaper that launched an investigative series regarding BPA (the Milwaukee Journal Sentinel). The study concludes by considering what the findings suggest about how social forces shape coverage of scientific controversies involving environmental issues.     

企业环境寻求、污染密集型生产区际转移与环境监管

在当前强调产业结构调整的政策背景下,产业有序转移必须以有利于或者加强环境保护为基本目标。环境规制差异造成了不同经济地域之间污染密集型生产的比较优势调整,强化了高污染产业进行生产区位选择的动机,以规避来自政府的环境监管。环境治理成本的不同是高污染企业区际转移的重要驱动因素,企业环境寻求策略推动了污染密集型生产由环境规制强度高的地区向环境规制松弛地区的转移。企业污染密集型生产的区际转移受到环境要素产品生产比较优势的明显影响,这些环境要素产品与区际环境规制差异、企业市场内部化战略以及污染密集型产品的生命周期密切关联。借鉴一般均衡分析框架,可以明晰企业环境寻求策略下污染密集型生产转移的内在机制。一方面,环境成本差异决定了非环境友好产品生产转移的意愿,高强度的环境规制使得企业生产的边际环境治理成本和平均环境治理成本提高,污染密集型生产外迁的动力加强,生产效率高的企业对环境规制强度更加敏感。污染密集型生产承接地提高环境规制强度能形成对环境负面影响的有力对冲,遏制环境恶化趋势。另一方面,合理的区际环境政策差异能在产业有序转移中发挥重要作用。合理设定区际环境规制级差与碳信征信系统建设,加强分类监管与行业节能减排,建立拟承接生产项目的效率筛选机制,提高区域市场开放程度、降低产业优惠政策所形成隐性市场保护等环境监管手段是保证欠发达地区通过产业承接实现跨越式发展的关键所在。     

我国在国际贸易中表现出“环境相对比较优势”吗?——兼与王奇老师商榷

我国在国际贸易和国际分工中是否表现出环境相对比较优势?本文通过考察进出口产品结构变化和我国吸引的外国直接投资的行业结构变化趋势对这一问题进行了实证分析,结果发现我国进出口产品结构没有向污染密集型产品转变,外商投资的行业结构也没有偏向污染密集型产业.虽然我国目前经济增长的自然资源和环境成本较大,但这主耍是国内资源使用效率低下和国内消费升级、产业结构转变造成的.实际上,参与国际贸易和国际分工使我国的经济结构向更清洁的方向转变,有利于减轻我国经济增长中的环境压力.因此,本文认为虽然目前我国的环境规制水平较一些发达国家低,但这并不等同于我国经济具有或表现出了环境相对比较优势,所谓的环境相对比较优势在实际上是不存在的.     

21世纪以来中国产业扶贫研究脉络与主题谱系

反贫困历来是发展研究中的最重要议题之一,尤其是进入21世纪以来,产业扶贫已日趋成为具有中国特色的反贫工作重心任务,受到学界和社会的热切关注,因此有必要对其研究脉络与热点主题等内容进行深入探索,以更好地促进产业扶贫实践的发展。本研究以2000—2015年间CNKI数据库收录的1 982篇产业扶贫研究的期刊论文为样本,采用文献计量分析法和可视化知识网络分析工具Cite Space,首先对中国产业扶贫研究总体现状进行了概述,然后着重分析了产业扶贫研究历经的四个演进阶段:初创期、探索期、爆发期和深化期,并描述了研究的整体发展脉络所沿着的四条轨迹,即产业扶贫主体由政府主导逐渐演变为政府主导、市场力量和社会参与并重;扶贫对象由农村贫困地区和人口逐步转向城市贫困人口,农村和城市扶贫两者并重;扶贫渠道由财政资金扶持逐步扩散到科技扶贫、智力扶贫、旅游扶贫等多元化方式;扶贫思路由农村推进向城市扶贫过渡,再到协调区域发展的精准扶贫战略。在此基础上挖掘和探讨了当前研究的热点主题,包括产业扶贫的发展历程、内涵与理论基础、模式与机制、现实困境与对策,以及经济效应等五个方面。最后指出当前研究成果在理论深度与体系构建、实践模式提炼、研究视角和地域、实证研究方法等方面存在不足,并提出了未来重点研究方向需要从高度重视产业扶贫与精准扶贫和参与式治理之间的内在逻辑,加快推进产业扶贫的本土化特色研究,以及鼓励跨学科视角的研究、注重规范研究与实证研究的协同三大方面展开探索。     

Framing environmental indicators: moving from causal chains to causal networks

In recent years, there has been a boom in environmental assessment reports utilizing environmental indicators. Most of these publications are based on the casual chain frameworks (e.g., Pressure–State–Response (PSR), Driving force–State–Response (DSR), and Driving force–Pressure–State–Impact–Response (DPSIR)). These frameworks have made an important contribution by emphasising the importance of causality. However, the reliance on simple uni-directional chains is at the same time not very conducive to a good understanding of the complexity of the processes behind environmental indicators. This limits the usefulness of these frameworks for environmental (impact) assessments. In this paper we propose an enhanced DPSIR (eDPSIR) framework for environmental indicators that takes inter-relations of indicators into account by relying on the use of causal networks rather than causal chains. It will be shown how the concept of causal networks can increase insight into the inter-relation of environmental issues and associated indicators, can facilitate the identification of key indicators for particular kinds of questions, and can provide a useful first step to the establishment of dose–response functions. Working with causal networks can contribute to more appropriate environmental policies and better management decisions.     

Secondary arsenic minerals in the environment: A review

Information on arsenic (As) speciation in solid materials is critical for many environmental studies concerned with As stability and/or mobility in natural As-impacted soils and mining or industrial sites contaminated by As. The investigation of these systems has provided evidence for a number of secondary As minerals that have often played a significant role in As mobility in the solid phase–water system. This paper presents a list of environmentally important secondary As minerals in contaminated soil and waste systems, summarizes the information about their origin, occurrence, environmental stability and thermodynamics, and proposes several important avenues for further investigation.     

贸易、外商直接投资、经济增长与环境污染

选取1990—2002年中国30个省市贸易、外商直接投资(FDI)、经济和环境相关数据，从定性和定量描述的角度探讨贸易、FDI对我国环境库兹涅茨曲线(ECK)的影响。研究表明：贸易对中国的ECK没有直接影响。但考虑到贸易对经济增长的贡献，以及它在引进先进污染防治技术和环境管理思想方法方面的积极作用，积极发展对外贸易将有助于改善我国经济增长带来的环境污染问题。另一方面。FDI与污染物排放之间呈现出显著的正相关关系。在中国接受经济全球化影响的过程中，由于部分地区急于吸引外资，加之环境管理体系的不完善，外商直接投资在某些方面对我国环境造成了一定的负面影响。

The Impact on Environmental Kuznets Curve by Trade and Foreign Direct Investment in China

1 INTRODUCTIONAs the globalization of world economy speeds up,international trade and foreign investment mainly bytransnational corporations are continuously expanding.It is against this background that the relationship betweentrade, FDI, economic growth and environmental pollutionstarted to attract close attention from scholars both athome and abroad (Dean, 1992; 2001; Copeland andTaylor, 2003; OECD, 1997; Beladi, 1999; MA, 2003).Although the idea that "economy and environment win-w…     

A follow up of the decrease of non exchangeable organically bound tritium levels in the surroundings of a nuclear research center

In the past decades limited amounts of tritium were handled on the CEA site of Bruyères le Châtel with authorised atmospheric releases. A small fraction of the tritium released entered into environmental samples under three forms: (i) as part of free water (TFWT - Tissue Free Water Tritium), or associated with organic matter in two ways; either (ii) bound to the oxygen and nitrogen atoms of the material as exchangeable organically bound tritium (E-OBT), or (iii) bound to carbon atoms as non exchangeable organically bound tritium (NE-OBT). The first two components provide only a picture of atmospheric tritium concentrations at the sampling time as they are in equilibrium with atmospheric moisture and soil humidity. Unlike these exchangeable forms, however, NE-OBT is tightly bound to the organic matter and provides an integrated record of atmospheric tritium during the growing phase of the vegetation. We mapped NE-OBT in tree leaf samples in an area of about 25 × 30 km² around the centre of the CEA site and compared the results with those obtained during a previous sampling exercise in 1989. At this time, the activity levels were almost ten times higher than those observed presently in a similar area almost 20 years later which is consistent with the decrease of atmospheric releases issued from the centre. As the activity levels are now close to environmental background specific attention was also paid to the analytical procedure to ensure reliable low level NE-OBT detection.     

The Impact on Environmental Kuznets Curve by Trade and Foreign Direct Investment in China

Abstract

Based on data of trade, foreign direct investment (FDI), economic development and environmental conditions in China's 30 provinces between 1990–2002, this paper deals with the impact on Environmental Kuznets Curve (EKC) of trade and FDI in China. The results show no direct impact on EKC of trade, on the one hand. However, trade contributes significantly to economic growth, and has played a positive role in introducing advanced pollution prevention technology and environmental management methodology to China. Therefore, a proactive trade policy will help solve the environmental pollution problem brought by economic growth. On the other hand, there is a positive correlation between FDI and pollutant emission, which proves that FDI does have some negative influence on environment in China due to hasty introduction of foreign capital and inadequate environmental management system in China.
