生态城市特征性指标的辨析及其应用

生态城市是依据生态学原理提出的一类社会、经济、自然协调发展的城市.基于生态城市内涵建立的城市特征性指标对城市特征性要素的量化和评价,是将生态城市个性这一主观观念变为可操作性目标的主要途径.基于城市复合生态系统理论和生态城市"健康、安全和发展"内涵,探讨了生态城市特征性指标的辨析方法.以厦门为例构建了厦门生态城市特征性指标体系.评价结果揭示了厦门城市特有的生态环境和资源的总体状态为亚健康状态(0.69)、比较脆弱的中警状态(0.39)和一般持续的发展状态(0.63).与现实的分析调研结果相符.这表明生态城市特征性指标有助于研究者辨识和评价城市生态系统的特定复合特征,更有针对性地明确城市生态规划和建设的重点行动领域,从而为城市实施可持续发展战略提供决策依据.     

有机化改性海泡石对六六六吸附性能的探讨

分别采用阴阳离子表面活性剂对海泡石进行有机化改性处理,并对改性海泡石进行了吸附六六六实验.结果表明,未经有机化改性的海泡石对六六六各异构体去除能力由小到大依次为:γ-六六六(12.66%)、δ-六六六(12.79%)、α六六六(17.35%)、β-六六六(33.57%).经DOSO3Na有机化改性的海泡石对六六六各异构体的去除能力由小到大依次为:β-六六六、γ δ-六六六、α-六六六.经CTMAB有机化改性的海泡石对六六六各异构体的去除能力由小到大依次为:β-六六六、α-六六六、γ δ-六六六.有机化改性海泡石使体系中β-六六六大幅度增加,可能为有机化海泡石催化α、γ、δ各异构体向β异构体转化.     

Critical perspectives of sustainable development research and practice

Sustainable development has been intensely debated for more than twenty years, but real progress of our societies to become more sustainable is very slow. Therefore this special issue provides a forum for critical perspectives of Sustainable Development Research and Practice. The papers are grouped into three clusters: a. Sustainability Science, b. Economic Problems and c. Corporate Contributions to Sustainable Development.Although a single special issue cannot address the entire array of issues pertaining to progress of sustainability related research, the selected papers highlight special aspects of sustainability research either due to their theoretical contributions or because they report on valuable empirical evidence. The main goal of sustainability research should be to contribute to our understanding of sustainability problems and to develop and help to implement solutions to solve them. This can be described as the relevance of sustainability research. A precondition to gain relevance is the rigor of sustainability science: it has to be based on solid scientific principles and methods. Additionally it has to be regarded that Sustainable Development is dynamic and that it has both normative and practical aspects. It is concluded that sustainability science and practice should be based upon these four central aspects: rigor, relevance, normative aspects and dynamic     

环境科学领域中欧科技教育合作的探讨

欧盟高等教育有着悠久的历史,在环境科学领域处于世界领先水平。随着欧盟一体化进程的深入推进,中国工业化和城市化步伐的加快,环境科学领域面临着新的机遇和挑战,必将给中欧之间的科技教育合作创造更多的机会。面对新形势,有必要认真分析中欧在环境科学领域科技教育合作的现状与机遇,总结经验,找出问题,提出对策,进而促进中欧合作的健康发展。

基于AHP-熵权法的基层地震科普能力评价*

为提高基层地震科普评价工作的客观性和精准性,根据“环境-投入-产出-效果”的评价框架,建立涵盖保障能力、队伍能力、设施能力、产出能力、活动能力5类26项指标的基层地震科普能力评价指标体系,选用AHP-熵权法计算指标的组合权重;以天津为例进行验证,并提出相关工作建议。结果表明:建立的评价模型对于开展定量化的区域基层地震科普能力评价具有较强的参考价值,评价结果与实际情况基本相符;天津市基层地震科普在硬件建设方面取得较好成效,但整体能力依然偏弱,16个区平均得分仅为0.344 8;发展不平衡、软实力不足是制约当前发展最重要的2个因素;提出相关的工作建议可为优化基层科普工作布局、提高工作实效提供有益参考。     

Advancing injury and violence prevention through data science

Introduction: The volume of new data that is created each year relevant to injury and violence prevention continues to grow. Furthermore, the variety and complexity of the types of useful data has also progressed beyond traditional, structured data. In order to more effectively advance injury research and prevention efforts, the adoption of data science tools, methods, and techniques, such as natural language processing and machine learning, by the field of injury and violence prevention is imperative. Method: The Centers for Disease Control and Prevention’s (CDC) National Center for Injury Prevention and Control has conducted numerous data science pilot projects and recently developed a Data Science Strategy. This strategy includes goals on expanding the availability of more timely data systems, improving rapid identification of health threats and responses, increasing access to accurate health information and preventing misinformation, improving data linkages, expanding data visualization efforts, and increasing efficiency of analytic and scientific processes for injury and violence, among others. Results: To achieve these goals, CDC is expanding its data science capacity in the areas of internal workforce, partnerships, and information technology infrastructure. Practical Application: These efforts will expand the use of data science approaches to improve how CDC and the field address ongoing injury and violence priorities and challenges.
