Indicators of sustainable production: framework and methodology

This paper presents a new tool for promoting business sustainability — indicators of sustainable production. It first introduces the concept of sustainable production as defined by the Lowell Center for Sustainable Production, University of Massachusetts Lowell. Indicators of sustainable production are discussed next, including their dimensions and desirable qualities. Based on the Lowell Center Indicator Framework, the authors suggest a new methodology of core and supplemental indicators for raising companies' awareness and measuring their progress toward sustainable production systems. Twenty-two core indicators are proposed and a detailed guidance for their application is included. An eight-step model provides a context for indicator implementation. The paper concludes with a summary of the strengths and weaknesses of the methodology as well as recommendations for testing the indicators.     

试论地震台站的组织结构和激励机制建设

本文对地震台站在新时期的台站管理进行了论述。指出在防震减灾基础建设的重要时期,地震台站的管理,首先需要转变管理理念,同时应完善组织结构建设,建立激励机制。这是完成中国地震局确定的《与时俱进、开拓创新,为全面实现地震台站的现代化而奋斗》重要工作之一。     

分子生物学在渔业环境保护中的运用

分子生物学理论和技术在渔业环境保护与监测工作中的应用越来越得到人们的重视：生物体的多种酶已被用作监测水环境污染的指标；金属硫蛋白等生物体解毒体系在监测和防治水体重金属污染方面发挥显著作用；核酸是生物体遗传信息载体，以核酸质量变化监测水环境污染已取得较好的效果。据此就分子生物学在今后渔业环境保护中的运用提出了观点。

A New Modus Operandi for the Agricultural Economics Profession

Agricultural economics has, until the 1990s, enjoyeda reputation for relevance and usefulness to theagri-food industry and policy-makers. Thatreputation has been jeopardized by a growinginfatuation with models and quantification, and aconcomitant underemphasis placed on many complexproblems and issues of society. An illustrativeexample is explored, using agriculturalactivity-related damage to the natural resourcebase, environment and ecology. Agriculturaleconomists are urged to respond by broadening theirterms of reference and joining forces with otherdisciplines.     

建立我国安全生产应急救援标准体系的初步构想

我国安全生产应急救援工作日益受到政府和企业的重视，但是应急救援标准非常薄弱，造成应急管理和实际救援工作困难，建立安全生产应急救援标准体系是应急救援工作和保护人民生命财产的迫切需要。在总结国内外应急救援标准工作的基础上，本文提出了我国安全生产应急救援标准体系框架以及标准制定的原则和重点。     

NUTRIENT CONCENTRATION CRITERIA AND CHARACTERIZATION OF PATTERNS IN TROPHIC STATE FOR RIVERS IN HETEROGENEOUS LANDSCAPES1

ABSTRACT: A method is demonstrated for the development of nutrient concentration criteria and large scale assessment of trophic state in environmentally heterogeneous landscapes. The method uses the River Environment Classification (REC) as a spatial framework to partition rivers according to differences in processes that control the accrual and loss of algae biomass. The method is then applied to gravel bed rivers with natural flow regimes that drain hilly watersheds in New Zealand's South Island. An existing model is used to characterize trophic state (in terms of chlorophyll a as a measure of maximum biomass) using nutrient concentration, which controls the rate of biomass accrual, and flood frequency, which controls biomass loss. Variation in flood frequency was partitioned into three classes, and flow data measured at 68 sites was used to show that the classes differ with respect to flood frequency. Variation in nutrient concentration was partitioned at smaller spatial scales by subdivision of higher level classes into seven classes. The median of flood frequency in each of the three higher level classes was used as a control variable in the model to provide spatially explicit nutrient concentration criteria by setting maximum chlorophyll a to reflect a desired trophic state. The median of mean monthly soluble reactive phosphorus and soluble inorganic nitrogen measured at 68 water quality monitoring sites were then used to characterize the trophic state of each of the seven lower level classes. The method models biomass and therefore allows variation in this response variable to provide options for trophic state and the associated nutrient concentrations to achieve these. Thus it is less deterministic than using reference site water quality. The choice from among these options is a sociopolitical decision, which reflects the management objectives rather than purely technical considerations.     

论知识经济下经济安全评估及策略

随着知识经济的来临,经济全球化趋势越来越明显,国家间的经济联系不断增强,同时也随之产生的国家间的经济竞争不断加剧,使得国家经济安全受到威胁。笔者针对当前的经济发展特征,就如何提高国家经济安全水平以增强国际竞争力探讨了影响国家经济安全的因素。从多方面的、综合性的影响经济安全因素中,找到影响经济安全的基本要素,据此从统计的可行性角度,科学地构建了评估经济安全的指标体系。所构建的指标体系对综合评价一个国家和地区的经济安全具有一定的合理性和科学性。最后,提出了有关保证经济安全的策略,以便当我国在知识经济来临之时,保证经济快速发展,能在经济全球化中不断提高自己的国际竞争力。
