The Green Village project: a rural community's journey towards sustainability

In the South West of the UK, a growing number of rural and urban communities are exploring various pathways to a more sustainable living. The village of Belstone is among these pioneers of change through its Green Village project. It is a relatively affluent community and it has been a major challenge to engage people that are reticent to change their lifestyle and suspicious of the motives of the initiators. Based on a process of action research, this paper explores the attitudes and perceptions towards sustainability and how they influenced the people's engagement. We demonstrate that the partnership was effective in enabling the villagers engaged in the project to take control over the process. Behaviour changes were reported by the villagers actively engaged with the initiative. The Green Village did not “snowball” to the entire community; however, many of those who chose not to engage associated the word “Green” with traits that they did not identify with.     

Integrating waste,manufacturing and industrial symbiosis: an analysis of recycling,remanufacturing and waste treatment firms in Texas

The continually increasing volume of the waste stream has led to numerous calls for strategies to close the loop on material use through industrial symbiosis strategies which direct used material and products (wastes) back to production processes. By use of a survey of recycling, remanufacturing and waste treatment firms in Texas, this paper asks if these firms can operate as a bridge between production and consumption/waste to efficiently increase the flow of used materials and products back to production processes at the local level. The results suggest that while most materials and used products are collected locally, only some can be re(consumed) locally. Moreover, the firms face negative perceptions about their activities from industry and the public at large that likely slow both the rate of entry of new firms into these markets and the expansion possibilities of existing firms. In addition, the types of conventions that characterize the interactions of more successful firms are not well developed in this sector(s). It is unlikely that recycling, remanufacturing and waste treatment firms can become central players in the production, consumption and waste cycle loop until society develops production design, marketing and consumption philosophies that include recycling and remanufacturing at a fundamental level.

基于弹性理念的城市用地开发战略研究——以上海市宝山区为例

随着市场机制的不断完善,城市土地利用的不确定性需要在战略定位上具备更大的弹性以适应市场的发展。基于弹性理念,在对城市用地开发条件进行辨识的基础上,对土地开发的需求进行了弹性预测,依据人口极限计算出土地弹性需求值域的上下限,确定弹性范围,提出适应社会经济发展需要的用地开发战略目标,并找到将其变为现实的正确途径。在结构上从城市用地开发战略目标的确定、城市用地发展方向的定位以及城市用地模式的选择3个方面,对城市用地开发的战略研究做了深入分析。同时,引入新的思想和方法以及多学科多视角,定性与定量相结合来制定城市用地开发的战略目标。最后,利用上海市宝山区作为实例,对基于弹性理念的城市用地开发战略的研究做了实证分析。     

On The Research of Foreign and Domestic Human Capital Theory

Abstract

Human Capital Theory came into being in the middle and later periods of the 20th century. A lot of achievements have been made on the research in its connotation, measures of the value, investment and income, function mechanism and so on, by foreign scholars. In recent 10 years of the new Millennium alternation, the “steal business effect” and the structure of human capital on the mechanism of economic rise has become the two emphasis in current foreign Human Capital Theory's research. On the basis of foreign researches and Chinese situations, domestic scholars have enriched and developed it, but there are many disparities in its methods, aspects and levels between foreign and domestic researches.

稻田土壤砷、镉复合污染阻控技术研究进展

砷（As）和镉（Cd）是稻田土壤中最常见的有毒有害重金属元素,且易从土壤迁移到水稻籽粒中.目前,我国稻田土壤中As和Cd及其复合污染现象普遍,对粮食安全和人体健康均构成了严重威胁.As和Cd在土壤中的环境行为相反,对As-Cd复合污染的同步治理是当前水稻安全生产的关键技术难点.通过综述近年来同步阻控水稻对As和Cd吸收以及转运的若干实用技术,包括水分管理、钝化技术、淋洗技术、电动修复技术、植物修复技术、低累积水稻品种的选取以及叶面阻控技术,归纳并分析了各种技术的处理效果、作用机制和制约因素,提出了主要阻控技术的发展方向,指出构建区域高适配性综合技术模式的重要性,以期为稻田As-Cd复合污染治理和水稻安全生产提供参考.
