保定电厂冲灰水下渗污染地下水的数学模型

在对保定电厂储灰场冲灰水、地下水化学成分和环境水地质条件分析的基础上，运用一维均质数学模型，对灰水下渗污染地下水的状况进行了数值模拟预测。结果表明，灰水下渗已造成储灰场周围地下水污染，但短时间内不会对距储灰场5000m处的保定市水源地水质造成影响。     

对我国农业现代化深层次问题的思考

中国农业现代化不可能照搬西方发达国家，必须从实际出发，吸收欧美等国先进科学技术和经验及教训，合理利用自然资源，保护生态环境，同时还要利用具有中国特色的传统技术和国外的高新技术，建设符合国情的非传统农业现代化，并实施可持续发展战略。在此背景下，文章分析了农业现代化过程中面临的深层次问题，提出了发展对策。     

Ecological Determinants of Distribution Decline and Risk of Extinction in Moths

Abstract:  For successful conservation of species it is important to identify traits that predispose species to the risk of extinction. By identifying such traits conservation efforts can be directed toward species that are most at risk of becoming threatened. We used data derived from the literature to determine ecological traits that affect distribution, distribution change, and the risk of extinction in Finnish noctuid moths (Lepidoptera, Noctuidae). The ecological traits we examined included body size, larval specificity, length of the flight period, and overwintering stage. In addition, in monophagous species we examined the effects of resource distribution. Larval specificity, length of the flight period, and the overwintering stage each had an independent effect on the risk of extinction when the effects of other traits were controlled by entering all traits into the same regression model. Not a single trait predicted the risk of extinction when analysis was conducted without controlling for the other traits. This discrepancy among the results suggests that a single trait may not be enough to allow prediction of the risk of extinction. Instead, it seems that for successful, predictive conservation science data on several ecological characteristics are needed.

Meeting the Climate Change Challenge (MC3): The Role of the Internet in Climate Change Research Dissemination and Knowledge Mobilization

This paper explores the role that Internet and online technologies played in research dissemination and knowledge mobilization in a recent climate change research project, MC³. In addition, the team looked at the potential of online expert-practitioner research collaborations for these purposes. Electronic communication was seen as a key element for creating distributed networks essential to the project and for building new practitioner/research knowledge collaboratives. The paper discusses how online communication strategies and technologies were used for wide dissemination of its research outcomes. MC³'s research dissemination and knowledge mobilization strategies are analyzed, using engagement as the primary measure, to gain insights on the effectiveness and challenges of using Internet-based tools for communicating climate change innovations and actions.     

“Talking of citizenship … ” Exploring the contribution an intergenerational,participatory learning project can make to the promotion of active citizenship in sustainable communities

The value of participating in community projects for the creation of a sustainable community is widely recognised but there remains little research into the multiple dispositions, knowledge, and competencies necessary for building and maintaining such a community. This article examines a small intergenerational social learning project that brought together students from a local community college and members of the town community association to explore the concept of sustainability-focused citizenship. The project was founded on themes of active citizenship, social learning, and intergenerational interaction, and was jointly evaluated by the participants and the researcher. This article presents two key ways in which this community-based learning project contributed to the promotion of citizenship for a sustainable community – firstly, as effective preparation for citizenship for sustainability, through the development of knowledge, disposition, and competencies, and secondly, in the performance of citizenship during the course of the workshops, through the encounter with, and negotiation of, difference.     

Marginal recycling: place and informal recycling in St. John's,Newfoundland

Informal recycling networks are systems through which impoverished populations earn money and residents recycle waste which might otherwise go into a landfill. These networks, in which people voluntarily self-organise to collect recyclables, occur throughout the world. This article discusses results of an exploratory, qualitative study of one such network in St. John's, Newfoundland and Labrador which identifies motivational characteristics of the network and their implications for public policy. Through close attention to particularities of place, the research identified community interaction and community inclusion as two of the most active motivating factors within the studied network. The findings suggest public recycling programmes can increase public participation through greater attention to place-based motivational factors. Such participation could contribute to increased sustainability and reach of recycling programmes.
