Ideological and pedagogical tensions in an environmental sustainability education project: A review of adult education practices around Lake Fundudzi,South Africa

ABSTRACT

Research in poor communities in South Africa faces intellectual challenges and tensions which offer lessons for evaluating environmental education (EE). This article illuminates five such tensions that emerged during the course of an adult environmental education programme, implemented from 1999 to 2002, in communities surrounding the catchment of Lake Fundudzi in South Africa: tensions arose between traditional and modern concepts of community; between traditional and post-apartheid structures of local governance; between liberal empowerment and traditional conservationist ideologies; and also within and between environmental ideologies and research paradigms. Paramount among the lessons learned is the need to develop multi-, inter- and transdisciplinary (MIT) practices that are sensitive to local community and environmental needs, and to solutions expressed through local residents, community workers and academics – in other words, the recognition and affirmation of local indigenous knowledge systems (IKSs).     

分子印迹技术在毒品检测中的应用

分子印迹技术具有优越的识别性和选择性,在毒品检测中具有重要的研究潜力。分子印迹技术应用与打击毒品犯罪相结合,已成为当今法庭科学工作者研究的热点问题。本文阐述了分子印迹技术的基本原理,并对其在固相萃取、吸附分析、化学发光、传感器、色谱分析等毒品检测技术中的应用情况进行了综合概括,并展望了分子印迹技术领域的发展趋势。     

分子印迹技术及其在司法鉴定领域的应用

分子印迹技术（MIT）是制备对特定目标分子具有分子识别功能聚合物（MIPs）的一门技术,由于MIPs具有的选择性,被广泛应用于各领域。对MIT和MIPs进行了介绍,并对其在司法鉴定领域的应用进行了综述。
