贸易、外商直接投资、经济增长与环境污染

选取1990—2002年中国30个省市贸易、外商直接投资(FDI)、经济和环境相关数据，从定性和定量描述的角度探讨贸易、FDI对我国环境库兹涅茨曲线(ECK)的影响。研究表明：贸易对中国的ECK没有直接影响。但考虑到贸易对经济增长的贡献，以及它在引进先进污染防治技术和环境管理思想方法方面的积极作用，积极发展对外贸易将有助于改善我国经济增长带来的环境污染问题。另一方面。FDI与污染物排放之间呈现出显著的正相关关系。在中国接受经济全球化影响的过程中，由于部分地区急于吸引外资，加之环境管理体系的不完善，外商直接投资在某些方面对我国环境造成了一定的负面影响。     

Making sense of invulnerability at work—a qualitative study of police drivers

This paper reports a qualitative study of 54 police drivers who were interviewed about their views on police driver training, driving strategies and their accident involvement. Study of the transcribed interviews indicated that officers constructed narratives of themselves as being highly aware of hazards presented by other road users and they used a variety of discursive devices to minimise their own culpability and attribute risk elsewhere. Rather than maintaining a straightforward ‘illusion of invulnerability’ they were formulating a ‘topography of risk’ in which they were responding to hazards presented by suspects or other road users. Their meticulously detailed accounts of the circumstances surrounding accidents serve to place them as knowledgeable and impartial participants and create a sense of expertise and authority. Training initiatives could profitably seek to challenge this ‘topography of risk’ and sense of authority so that drivers more fully appreciate the hazard they may present to themselves and the public.     

中国的能源工业及其污染防治

能源工业是我国的基础工业,也是经济发展的战略重点,同时又是重要的污染源。由于我国能源以煤炭为主,所以能源工业的污染主要是煤的开采利用带来的。因此,应当把煤炭开采、利用造成的污染作为防治重点,从节能降耗、提高燃烧效率、改善能源结构、消除煤炭开采、利用中产生的污染等几个方面入手,从根本上解决能源工业的环境问题,努力处理好经济发展和环境保护的关系,实现能源与环境的协调发展和经济的持续增长。     

震后灾害损失快速评估

本文论述了震后灾害损失快速评估的三种方法,分别适用于城市、整个受灾区及农村。文中还提供了一系列平均统计数据,如建筑物震害率,平均损失率等,为当地无详细资料时参考使用。并以地震烈度和人口密度为参数,给出快速评估人员伤亡的经验公式。最后还讨论了地震间接损失的估算方法。     

基于高程的环境库兹涅茨曲线实证分析

本文利用GIS的空间分析技术。以高程带为取样单元。研究在高程带上三种主要的大气污染物与经济发展之间的定量关系。以重庆市为例,验证环境库兹涅茨在高程上是否存在。研究结果发现。污染物浓度随高程的增加呈非单调下降的趋势。人均GDP随高程的增加先增大后减小。在高程上。污染物浓度与经济发展之间的关系和两者在时间序列和国别（或地区）序列上环境库兹涅茨曲线研究的结论相似。其中。TSP和NOx分别与人均GDP之间呈较稳定的呈“N”形和饲“U”形关系。受人口密度和高程影响较大；而SO2与人均GDP之间关系不稳定。

The risk assessment–policy gap: An example from the UK contaminated land regime

Risk-based regulation assumes that risk assessment can evaluate risks against policy objectives. However, policy goals are often ambiguous and require risk assessors to interpret them for use in risk assessment. This risk assessment-policy gap stems partly from normative and imprecise policy language but is rooted more fundamentally in society's uncertain expectations for the environment. Until this uncertainty is resolved, the democratic and regulatory effectiveness of risk regulation will be undermined by ad hoc policy decisions abdicated to risk assessors.     

Ranging of songs with the song type on use of different cues in Carolina wrens: effects of familiarity

Male territorial song birds are usually spaced far apart and most often hear conspecific song after it has been degraded by propagation through the environment. Their ability to use the degradation of songs to assess the distance of a singing rival without approaching (called ranging) presumably increases the efficiency of defending a territory. In order to assess degradation in a song the receiver needs to compare the characteristics of the received song to its characteristics at the source or at different distances. Earlier experiments on ranging in species with song repertoires have suggested that prior familiarity with the particular song type is necessary for ranging. Here I show that male Carolina wrens (Thryothorus ludovicianus) can use either temporal or spectral characteristics for ranging song types which they were unlikely to have heard previously. Playbacks consisting of only one song prevented subjects' close-range experience with the loudspeaker, and flights beyond the loudspeaker provided direct evidence for over-assessment of distance when songs were degraded. Because ranging of songs was not affected by the degree of familiarity with the song type, this experiment provides no evidence that song repertoires hinder ranging in Carolina wrens, as suggested by Morton's ranging hypothesis. Instead, at least approximate ranging of songs is evidently possible by assessment of degradation in general features of a species' songs.

PROFILE: Integrating Sustainability and Environmental Impact Assessment

/ Environmental impact assessment (EIA) has been identified as an important instrument for facilitating sustainability. However, to do so requires the integration of sustainability into EIA theory and practice. The sustainability concept is a valid and important environmental management perspective. However, many issues and obstacles need to be addressed further if the concept is to be translated into practical strategies. Sustainability can potentially infuse EIA with a clearer sense of direction, an ethical foundation, a mechanism for establishing priorities and assessing choices, and a means of linking EIA to other environmental management instruments. Conceptually, EIA and sustainability can be integrated, but frameworks should be refined, adpated to context, and linked to related initiatives. Sustainability should be explicitly incorporated into EIA legislation, guidelines, and institutional arrangements. An experimental approach to testing, assessing, and sharing experiences is suggested.A framework is first presented that defines and characterizes the sustainability concept. A further framework is then described for integrating sustainability into EIA at the conceptual level. The integration of sustainability and EIA at the regulatory level is next addressed through an overview of sustainability initiatives in EIA requirements in Canada. The Canadian examples include many promising initiatives but these and other experiences will need to be monitored, shared, and integrated into comprehensive environmental management strategies. Finally, means of incorporating sustainability into each activity in the EIA planning process are identified.KEY WORDS: Sustainability; Environmental impact assessment     

Advisory Committee: A Powerful Tool for Helping Decision Makers in Environmental Issues

/ It has been suggested that the general public should be moreinvolved in environmental policy and decision making. It is important forthem to realize that they will have to live with the consequences ofenvironmental policies and decisions. Consequently, policy makers shouldconsider the concerns and opinions of the general public before makingdecisions on environmental issues. This raises questions such as: How can weintegrate the perceptions and reactions of the general population inenvironmental decisions? What kind of public participation should weconsider? In the present study, using a new regional ecosystem model, weattempted to integrate these aspects in its decision making model byincluding the formation of an advisory committee to resolve problems relatedto waste management. The advisory committee requested the activeparticipation of representatives from all levels of the community: economic,municipal, and governmental intervenors; environmental groups; and citizens.Their mandates were to examine different management strategies available inthe region, considering all the interdisciplinary aspects of each strategy,elaborate recommendations concerning the management strategies that are mostsuitable for all, and collaborate in communication of the information to thegeneral population. The results showed that at least in small municipalitiessuch an advisory committee can be a powerful tool in environmental decisionmaking. Conditions required for a successful consultation process, such aseveryday lay language and the presence of a facilitator other than ascientific expert, are discussed.KEY WORDS: Public consultation; Environmental policies;Interdisciplinary aspects; Municipal sewage sludge management; Generalpopulation; Decision-making process
