科学发展观与中国传统文化

从分析传统发展模式的种种弊端与现阶段我国经济增长方式存在的主要问题入手,论述了科学发展观的科学含义和现实意义,并试图从中国传统文化的角度去挖掘科学发展观深邃的思想内涵。     

The Impact of BSE and FMD on Ethics and Democratic Process

The recent crises of BSE and FMD in the United Kingdom have revealed widespread concerns on the part of farmers and consumers about government regulations and handling of animal movements, animal welfare, and food safety. Both crises raised issues of government accountability and the lack of openness in public debate. The issues of democratic process and decision-making were especially strong in relation to the mass slaughter policy of the government to control FMD. This article explores public disquiet about these matters, as expressed through the reports of two public inquiries, and the perceived links between government decision-making and the needs of global agribusiness, to the detriment of family farms and animal welfare. In light of the growing evidence about the environmental and economic costs of agribusiness, the argument is made that strong programs of citizen action, such as the Devon Foot and Mouth Inquiry, that are grounded in an ethical stance on animal welfare can challenge the perspectives of central governments about concepts of cost, efficiency, and safety in agriculture.     

“良心”与地震预报

地震科学水平和地震预报的社会实践，形成研究人员不同的“良心”心理活动。积极的“良心”心理活动，有促进地震预报研究发展，相对提高预报成功率的作用；消极的心理活动，则干扰地震预报决策，或涣散军心，增加预报失误。为此，在震情严峻的情况下，应减轻预报人员的心理负担，在基层地震部门，更要疏导地震工作者的消极心理，以提高地震预报的质量     

Timing of hurricane emergency actions

Emergency actions to prepare for hurricanes often require more time than is available from official public warnings. This means that the preparedness official must decide not onlywhat to do butwhen to do it. The action decision system, described here, developed for use in the State of Florida, reformats the hurricane track forecast, a 72-h projection, prepared at the National Hurricane Center in Miami, to specify the probability of a strike at each of 12 vulnerable coastal communities, and then normalizes the value in terms of a composite of probabilities computed for historic hurricanes that struck the respective communities. The normalization, a ratio of the two probability values, current and historic, expressed as a percentage is defined as the level of risk. When this level reaches or exceeds 100% the risk level is defined as critical and the system recommends that emergency actions to prepare begin immediately.The system is founded upon individual hurricane climatologies and decision procedures that are tailored for use at each community. The action recommendations generated by the risk analyses with a 93% level of confidence relieve the preparedness official of the need to make meteorological decisions in timing evacuations and other critical measures, even when these must begin before official hurricane warnings are received.The work that provided the basis for this publication was supported by funding under a Cooperative Agreement with the Federal Emergency Management Agency.

Community and individual reaction to environmental hazards: Developing a measurement technology

This study was an attempt to develop an efficient method of monitoring and assessing how members of a community react to a toxic hazard in their community. The intent was to develop a short instrument which could be applied in multiple settings, or in the same setting several times. The methodology was a short questionnaire that addressed six issues: sources of information about the hazard, beliefs about justice and responsibility, beliefs about why the hazard is a problem, extent of active concern, involvement in community affairs, and satisfaction with life. A mailed questionnaire was developed and tested in a community near an EPA Superfund site in the United States. Results of the effort are discussed relative to the particular community studied, and relative to furthering the assessment technology begun in this research.     

FLOOD WARNINGS AND FLOOD RESPONSES FOR THE RED RIVER OF THE NORTH1

ABSTRACT The flooding conditions in the basin of the Red River of the North are reviewed in terms of the accuracy of the flood forecasts and the response of both the floodplain occupants and government agencies to these forecasts. The flood prediction methods in Canada and the United States are compared. The accuracy of these prediction measures for the major floods in recent history is reviewed. The differences between the way in which the American and Canadian authorities approach the flood emergencies are outlined. The accuracy of the forecasts are plotted against a number of parameters which reflect the efficiency of the flood fighting measures initiated by those flood forecasts. The significant features of these plots are discussed.     

Living with Pollution in Egypt

Environmental issues are increasingly discussed in Egypt, and there is some progress in dealing with pollution. This paper examines the environmental understandings of Egyptians living in four localities. People are preoccupied with such pollution problems as dirty streets, dirty air and water, and noise, for they aspire to live in a clean, healthy environment. To achieve this, they pressure the government, and take certain individual and collective actions themselves, although direct political action is rare.     

Conservation of Biodiversity: How Are We Doing?

A question rarely raised in discussions on biodiversity conservation, but surely the biggest question of all, is “How much time do we have left before the mass extinction underway surpasses our best efforts to contain it?” This prompts a further prime question because—and unlike all other problems, whether environmental or otherwise—the biotic crisis threatens to leave a severely impoverished planet for millions of years ahead; “Why do we not undertake the necessary actions to get on top of the problem before it gets on top of us?”     

Take Action Now: Motivational Framing and Action Requests in Climate Advocacy

This article explores similarities and differences between Internet-mediated climate change advocacy organizations and their legacy counterparts. It relies on a content analysis of advocacy emails produced by Environmental Defense Fund, Natural Resources Defense Council, Sierra Club, Greenpeace USA, League of Conservation Voters, Climate Reality Project, 1Sky, and 350.org. The study finds differences and similarities in strategic Internet use, including greater emphasis by climate groups on high threshold, offline actions; greater emphasis by legacy groups on low threshold, online actions; and high reliance by both framings that demand accountability from political elites. Implications for Internet-mediated and climate advocacy are discussed.     

混合污染物联合毒性评价模型曲线和实际浓度效应曲线之间交叉现象的研究进展

许多研究在使用评价模型进行混合物联合作用模式判别时发现,混合污染物的评价模型曲线和浓度效应曲线之间存在交叉的现象,表现为联合作用模式随混合物浓度发生变化。虽然交叉现象不断被报道出来,但是该现象形成机制的研究却非常欠缺。本文系统分析了文献中出现的交叉现象,探讨了交叉现象可能的形成原因和机制,提出了化合物的hormesis效应是导致交叉现象的关键因素:混合组分中某些化合物在低浓度时会对受试生物的某些蛋白、基因等的表达量产生刺激作用,影响其他化合物对机体产生的效应,从而改变混合组分的联合作用模式。该研究不仅为交叉现象形成机制的进一步探索提供了理论依据,还为混合物的生态毒理评估和环境风险评价提供理论指导。
