From a literature review to a conceptual framework for sustainable supply chain management

Academic and corporate interest in sustainable supply chain management has risen considerably in recent years. This can be seen by the number of papers published and in particular by journal special issues. To establish the field further, the purpose of this paper is twofold. First, it offers a literature review on sustainable supply chain management taking 191 papers published from 1994 to 2007 into account. Second, it offers a conceptual framework to summarize the research in this field comprising three parts. As starting point related triggers are identified. This allows putting forward two distinct strategies: (1) supplier management for risks and performance, and (2) supply chain management for sustainable products. It is evident that research is still dominated by green/environmental issues. Social aspects and also the integration of the three dimensions of sustainability are still rare.Both practitioners in companies and academics might find the review useful, as it outlines major lines of research in the field. Further, it discusses specific features of sustainable supply chains as well as limitations of existing research; this should stimulate further research.     

鸟粪石分析与表征技术综述

对X射线衍射（XRD）、傅里叶红外光谱（FT—IR）和拉曼光谱（Ralnan）、热分析（TGA）及化学分析法等技术用于分析和表征鸟粪石的最新研究进展进行了综述。表明X射线衍射、傅里叶红外光谱和拉曼光谱等能定性判断所得沉淀中是否含有鸟粪石,而难以定量分析鸟粪石含量。通过元素分析以及由此而建立的鸟粪石含量计算方法可以定量确定沉淀中鸟粪石的含量。热分析能提供热性能信息从而为所得沉淀的干燥处理过程提供有用的依据。     

国内旅游地水环境研究综述

水环境问题是旅游环境研究的重点领域之一。本文从研究理论、方法、区域和内容方面对国内水环境研究作一系统综述,并指出目前我国旅游水环境的研究理论较侧重水环境专业理论,与旅游结合的理论运用不足;研究方法注重一般的环境影响评价方法,社会方法运用较少;研究区域注重水域型旅游地,海滨海岛及山岳、古村落等旅游地较少;研究内容侧重旅游对水环境的自然影响,水资源利用及社会影响研究较少。     

我国农村室内空气污染干预状况综述

概述了1994-2006年国内外对我国农村室内空气污染干预的研究成果,从中总结了改炉改灶、健康教育与行为干预、开发和使用清洁能源、社会动员等4项干预措施.其中,使用改良炉灶和清洁能源可直接而有效地改善室内空气质量; 健康教育、行为干预与社会动员通过帮助人们改变不良的生活方式达到改善室内空气质量的目的,这些措施在我国农村室内空气污染干预中取得了很好的效果.建议结合我国各地实际,采用综合干预措施控制农村室内空气污染.     

Supercritical water oxidation for the destruction of toxic organic wastewaters： A review

The destruction of toxic organic wastewaters from munitions demilitarization and complex industrial chemical clearly becomes an overwhelming problem if left to conventional treatment processes. Two options, incineration and supercritical water oxidation （SCWO）, exist for the complete destruction of toxic organic wastewaters. Incinerator has associated problems such as very high cost and public resentment; on the other hand, SCWO has proved to be a very promising method for the treatment of many different wastewaters with extremely efficient organic waste destruction 99.99% with none of the emissions associated with incineration. In this review, the concepts of SCWO, result and present perspectives of application, and industrial status of SCWO are critically examined and discussed.     

制糖废水的主要处理工艺及发展方向刍议

制糖废水是一种高浓度的有机废水,按污染程度可分为低浓度废水、中浓度废水、高浓度废水三种类型。这种废水的主要处理工艺有物化法和生化法,以及各种方法相结合的组合工艺。本文就这种废水的处理方法作简要综述,分析各处理工艺的优缺点,为制糖废水的处理提供参考,最后提出制糖废水的处理发展方向。

China’s Total Emission Control Policy: A Critical Review

Abstract

As part of a comprehensive environmental management system, many countries establish emission control targets for mass emissions of a pollutant. Such targets are often the key objective of an environmental policy, such as an emission trading program. In China, however, it is more than just an objective of one particular policy; it has become a concept that has influenced many national environmental policies and activities. The objective of this article is to review the implementation of the total emission control policy in the past 10 years and explore emerging issues in its implementation. The article has three sections: a summary of the implementation experience, issues with the design and implementation of the policy, and policy recommendations.     

Ethnographic understandings of ethnically diverse neighbourhoods to inform urban design practice

The aim of this paper is to inform urban design practice through deeper understanding and analysis of the social dynamics of public outdoor space in ethnically diverse neighbourhoods. We hypothesise that findings from ethnographic research can provide a resource that improves cultural literacy and supports social justice in professional practice. The primary method is a meta-synthesis literature review of 24 ethnographic research papers, all of which explore some dimensions of public open space use and values in UK urban contexts characterised by ethnic and racial diversity. We summarise thematic understandings and significance of neighbourhood places of shared activity, parks, spaces of passing-by and of retreat. We evaluate the implications for intercultural social dynamics, exploring the spatial and temporal dimensions of conviviality and racism in public open space. We then argue that it is possible to develop principles for urban design practice informed by this work, and propose four for discussion: maximising straightforward participation, legitimising diversity of activity, designing in micro-retreats of nearby quietness and addressing structural inequalities of open space provision. We conclude that ethnographic research can provide detailed insights into the use of the public realm and also inform a more nuanced understanding of outdoor sociality relevant for an increasingly diverse society. The challenge is two-fold: for ethnographers to become less cautious in engaging with decisions and priorities regarding how cities change, and for urban designers to explicitly embed informed understandings of difference into their broad desire for inclusive public space.     

清洁生产审核中无/低费方案的产生及实施

清洁生产审核是实施清洁生产最有效的,也是最具可操作性的方法。在清洁生产审核预评估和评估阶段提出可行的无/低费方案,并按照"边审核边实施"的原则对所提的无/低费方案加以实施,能够使企业在短时间内达到"节能、降耗、减污、增效"的目的。以某化肥企业为例,找出企业存在的问题,评估企业的产排污情况,有针对性地提出了无/低费方案,并得以实施,为企业创造了一定的经济效益和环境效益。
