Understanding self-evaluations of effectiveness by forestry advisory committee members: a case of Ontario's Local Citizens Committee members

Researchers have devised many criteria that could assist with the development of an effective public participation process. Few studies, however, have linked these criteria to the effectiveness of decision-making resulting from these processes. We assess whether several criteria postulated by others for designing an effective decision-making process are associated with evaluations of the effectiveness of decision-making by advisory group members from a forest management planning process in Ontario, Canada. Data were collected by written questionnaires from 197 advisory group members in 2001. Four criteria were linked to the effectiveness evaluations including process control (influence), trust in decision-makers, information credibility, and process efficiency. The criterion of knowledge along with contextual variables related to experience, economic dependence on forestry, and geographical residence were not associated with evaluations of effectiveness.     

溧阳市1985~2011年环境空气质量变化规律的模糊综合评价

选用模糊综合评价法,对溧阳市1985~2011年环境空气质量进行了综合评价,选用SO2、NO2、TSP/PM10作为评价因素,通过计算各评价因素权重分配系数和隶属度,分析了长期空气环境质量变化趋势。结果表明:TSP/PM 10为1985年以来溧阳市首要环境空气质量制约因素,20世纪80年代中期全市空气质量主要隶属于一级标准,20世纪80年代后期主要隶属于二级标准,20世纪90年代初期主要隶属于三级标准,20世纪90年代中后期至今主要隶属于二级标准,近几年受TSP/PM1 0因素影响,在三级标准的隶属度有上升趋势;自20世纪90年代中期始,NO 2超越SO2成为继PM 10之后制约空气质量的第2大因素;经济发展对环境空气质量的规模效应较为显著,技术减排效应逐步显现。     

岷江上游河流健康状况的表征及评价

河流健康状况评价是河流管理和河流生态系统监控的基础。本文针对水电开发程度较高的岷江上游开展河流健康状态标识及评价研究。尝试从河流结构、生态环境功能、社会服务功能3个方面袁征河流的健康状况,其中引入鱼类生物完整因子,结合岷江上游水生生态特点及国外研究现状拟定了12个指标对该因子进行表述;并采用多目标模糊评价模型,在确定岷江上游指标权重与指标标准特征值前提下,开展健康评价。评价结果表明：岷江上游由于电站的建设导致枯水期减水河段的河流动力大幅度下降;蜿蜒度以及水质状况良好;减水河段长度比及纵向连通性较差,岷江上游鱼类生物完整性属差的状态,社会环境功能指标一般。河流的综合健康状况处于较差状态,需采取一定措施对其进行生态修复以期恢复到相对健康的状态。     

省级环境保护规划引入第三方评估的分析及建议

为进一步提升省级环境保护规划评估的公开透明程度和技术水平,也为了丰富省级环境保护规划评估的技术手段,有必要在省级环境保护规划的实施情况的评估工作中引入第三方评估。文章在对第三方评估存在的优缺点和实际操作中可能存在的问题进行分析的基础上,提出以下建议:全面加强第三方评估制度的建设;制定第三方评估任务范式合同及相关技术标准;明确被评估机构和人员在评估过程中的权责;参与省级环境保护规划评估的相关组织和机构应加大评估专业技术的学习和研究,提升评估技术水平。     

Preventing femoral fractures among elderly: The community safety approach

The current picture of fatal injuries in Sweden is dominated by falls, which account for about 40%. Furthermore, falls are by far the most dominating cause of hospital in-patient care (57%). The aetiologic mechanisms behind falls and fractures are complicated, with a multifactorial causal pattern.The Lidköping Accident Prevention Programme — one of the few comprehensive community intervention programs in the world — provides an opportunity to discuss links between a multifactorial intervention program and related injuries in the elderly. The incidence of femoral fractures in Lidköping shows a significantly declining trend for females (− 6.6% per year) and a − 5.4% decline for males during the study period of 1987–1992. The control area of Skaraborg County showed a minor decrease and Sweden as a whole showed an increasing trend during the same period.In spite of the methodological problems of attributing effects in quasi-experiments, there is some support for the claim that the declining trend in the trial area was largely the result of the intervention program. This conclusion is further strengthened by the recently published report from the USA showing that a multiple-risk-factor intervention strategy resulted in a significant reduction in the risk of falling among elderly persons in the community.     

工厂安全性评价指标体系科学性的间接测定方法

工厂安全性评价指标体系是评价工厂安全性工作的测定标准，指标体系的科学性和合理性与工厂安全性评价工作密切相关。工厂安全性评价指标体系科学性的间接测定方法是，采用直接测定结果作为间接测定指标体系的样本，再利用各指标之间的相关量，求出间接测定结果，通过直接评价结果与间接评价结果的比较，检查直接评价结果的准确程度，以分析修正指标体系。

Environmental impact assessment in flanders,belgium: An evaluation of the administrative procedure

Two years of experience with EIA in Flanders (northern Belgium) was evaluated in order to gain perspective on the effectiveness of the administrative procedure. The four essential characteristics of the EIA procedure that were evaluated are: completeness, open and public character, objectivity, and verifiability. Representatives of all parties involved in the EIA procedure were interviewed. The result of the evaluation is a list of major problems with EIA. Recommendations for a more efficient procedure are suggested at a time when a proposal for a new, comprehensive, and permanent EIA decree is being discussed. The evaluation of the administrative procedure for EIA in Flanders shows that several vital characteristics of the EIA procedure are lacking. This reduces the obligatory and open nature of the process, resulting in insufficient guarantees that the environment receives the altention it deserves during the decision-making process.
