作为同被环保部列为首批排污权交易试点地区的湖北和江苏,通过多年的试点工作,两地都取得了一定经验。通过全方位对比两地排污权交易制度,包括初次分配、配套优惠政策以及排污监测等,找出湖北省目前排污权交易工作陷入停滞、排污权交易市场惨淡的原因,提出改善初始分配方式、制定相关激励政策、扩大交易对象和范围、加强环境监管等对策,以期为政府决策提供参考。 相似文献

旅游公路景观协调性评价指标权重模型研究 总被引:3,自引:1,他引:2
为评价旅游公路景观协调性,通过对影响旅游公路景观协调性因素的分析,采用目标分解法初选评价指标,确定公路景观与交通安全、景观与视觉、景观与生态环境协调性3个目标层。在此基础上采用德尔菲法建立景观协调性评价指标体系;将景观协调性指标权重分为价值量权重和信息量权重2部分,在序关系分析法基础上充分利用指标值信息,综合主、客观赋权法,建立旅游公路景观协调性评价指标组合权重模型。结果表明:该模型可客观有效地确定各评价指标的权重。 相似文献

Although a large number of medical error taxonomies have been published, there is little evidence to suggest that these taxonomies have been systematically compared. This paper describes a study comparing 26 medical error taxonomies using a human factors perspective. The taxonomies were examined to determine if they classified systemic factors of medical errors and if they utilized theoretical error concepts in their classifications. Scope of classification was also examined. It was found that two-thirds of the taxonomies classified systemic factors of medical errors and only a third utilized theoretical error concepts. Medical error taxonomies based on theoretical error concepts were more likely to be generic in applicability and also more likely to classify systemic factors and psychological error mechanisms of medical errors. In addition to terminology, the medical error taxonomies also varied in terms of domain-specificity, granularity, and developmental process. Different medical error taxonomies provide different information; how these differences affect medical error management needs to be investigated. 相似文献

The aim of this paper is to suggest an effective procedure to eliminate a major deficiency in impressed current cathodic protection (CP). Current work describes performed activities through jetty cathodic protection troubleshooting as a case study. Although CP troubleshooting is straightforward, sometimes it is very complicated and confusing. To eliminate the appeared imperfection, different procedures were carried out; the root cause of the trouble in the system was shown to be in reversed current. Here the current which passed throughout installed junction were measured to survey reversed current. Current work offers a new approach in CP troubleshooting. 相似文献

Schuler's process model of employee participation in decision-making and job satisfaction (Schuler, 1980; Lee and Schuler, 1982) was tested using a path analytic approach. Reanalysis of Schuler's data and replication on a new sample indicated that (a) participation in decision-making has both direct and indirect effects on job satisfaction; and (b) performance–outcome expectancy, role conflict, and role ambiguity all appear to mediate the relationship between participation and satisfaction. In an extension of the model, organizational level and job involvement were hypothesized to moderate the participation–satisfaction relationship (i.e. function interactively). Although neither variable functions as a moderator, job involvement operates in a fashion similar to participation in the model. In general, consistent results across four independent samples strongly support Schuler's basic process model. 相似文献
