Indicator framework for sustainable production planning and controlling

Production facilities serve to transform raw materials into products, usually with the goal of achieving a designated output, in terms of quantity and quality, with the minimum of cost and labour. With the aid of production planning and controlling (PPC) systems, raw material inputs, and labour can be planned to achieve a determined output of products. In general, the role of environmental and social aspects is neglected in production planning processes. Because of the growing pressure from politics and customers, sustainable production of products is becoming more important. One possibility for supporting sustainable manufacturing is, to integrate sustainable aspects in the production planning process. This paper presents input and output information for current PPC systems and discusses the need for additional information necessary for sustainable PPC. For this approach, a text review of cooperate social responsibility (CSR) reporting indicators provided by the GRI was performed. Based on the text review, an input-output model has been developed for conventional and another one for sustainable PPC systems. Through the comparison of the two input-output models, challenges and requirements for sustainable PPC systems have been defined as a basis for future work and analyses.     

泥石流坝后侵蚀坑纵剖面形态及最大深度实验研究

泥石流拦砂坝坝后侵蚀坑形态和深度是泥石流冲刷基础研究的薄弱环节。通过室内水槽实验,探讨了泥石流坝后侵蚀坑的形态和不同实验控制条件下侵蚀坑深度的变化规律等。由实验观察可知,侵蚀坑纵剖面整体上呈现两端浅中间深的形态特征,其最深点的位置随水槽坡度增大向下游方向发展;侵蚀坑坑内上游坡度较下游坡度陡,对于具有相同级配的粘性砂和无粘性砂,无粘性砂的侵蚀坑坑内坡度较粘性砂的缓;侵蚀坑的最大深度受沟床纵坡、泥石流的容重、沟床组成物质的性质(特征粒径、粘性)等因素的影响较大;泥砂粘性的存在将大大削弱侵蚀的深度。

地域系统研究进展与展望

在述评国内外地域系统研究的基础上．分析了目前在“生态”框架下进行综合地域系统研究中存在的问题。①生态区是一个开放系统。任何尺度下的生态区都是由不同的生态系统组成。因此生态区的同质性是相对的，导致区划单元界线划定存在分歧。②受基础数据资料精度的限制．指标选取较多考虑是否能够满足数理统计需要而在一定程度上忽视了生态学上的意义和作用。③人类活动在生态区中既受到自然因子的制约．也对自然因子产生偏移，区域社会经济发展模式是自然、人文因子综合作用的结果．因而生态区包含自然因子和人文因子的信息。文中指出掌握自然-人文因子相互作用机制实现自然-人文因子的拟合是综合地域系统研究的核心．运用自然-人文因子空间化技术进行多源数据的融合是划分综合地域系统必须解决的关键技术．同时对将自然-人文空间化技术手段应用于综合地域系统划分中需要解决的问题进行了探讨。     

Food for Thought: Audience Engagement with Sustainability Messages in Branded Content

Branded platforms are a growing “gray-zone” of marketing and media messages, in which corporations and news journalists partner to create content that supports strategic corporate goals while aligning with a publication’s scope of editorial coverage. As corporations are key influencers of and contributors to environmental communication, this trend has the potential to change environmental dialogue. In this article, we closely examine messages about food and sustainability, created in partnership by Chipotle Mexican Grill and the Huffington Post news site. We illustrate how use of a branded platform expanded the scope of environmental topics, issues, and frames that Chipotle addresses, how frames identified here connect to frames in coverage of science-related issues, as identified by other scholars, and discuss how branded platforms allow corporations to draw attention to polarizing environmental issues while protecting stakeholder relationships and brand reputation.     

Mitigating urban sprawl effects: a collaborative tree and shade intervention in Phoenix,Arizona, USA

Communities in Phoenix are confronted with numerous challenges that adversely affect human health and safety, with disproportionate impacts on low-income communities. While some challenges are being addressed at the city level, new alliances at the neighbourhood level are initiating community development programmes and projects. This article reports on an intervention study carried out in collaboration with community representatives, city staff, and non-profit organisations to mitigate adverse effects of urban sprawl in the Sky Harbour Neighbourhood in Phoenix. Participatory research was conducted to design and test a tree and shade intervention. Challenges associated with navigating community desires and broader principles of sustainable development are discussed. The study offers a replicable and adaptable intervention research design aimed at empowering communities to meet urban challenges.     

化工园区突发环境事件应急预案编制的研究

我国的化工园区为促进经济和社会发展做出了重要贡献。由于化工园区内危险化学品种类多、有毒有害物质数量大、环境风险等级高,存在着发生重特大事故的现实性和可能性。但是,我国至今尚未制定化工园区突发环境事件应急预案编制技术规范,相关研究也未见报道。在当前化工园区安全生产事件高发并严重影响周边环境的情况下,研究化工园区突发环境事件应急预案编制方法,提高应对安全生产事故以及次生突发环境事件的能力尤为重要。通过分析化工园区环境风险物质、环境风险工艺和环境风险受体三个方面的环境风险的特性,初步拟定了化工园区突发环境事件应急预案编制调查评估、建章立制、预案编写三个阶段的技术路线,明确了开展环境风险评估、加强应急能力建设、完善环境风险防范措施和环境应急处置措施的四项编制要点,在此基础上提出了化工园区突发环境事件应急预案由综合预案、现场处置预案、专项预案、环境风险评估报告、环境应急资源调查报告六部分组成的结构框架。
