新型农村合作医疗和财政补贴对我国乡镇卫生院发展的影响

对我国乡镇卫生院2004～2010年实施新型农村合作医疗（简称新农合）后的发展状况进行实证分析,从新农合补偿受益人次与卫生院医疗服务情况、乡镇卫生院盈余及净资产方面探讨新农合和财政补贴对乡镇卫生院发展的影响。得出结论,新农合虽然促进了乡镇卫生院的发展,但乡镇卫生院的发展仍需要财政或上级的经费补偿,最后提出部分建议。     

基于可拓理论的机械设计方案评价方法

基于可拓理论提出了机械设计方案的可拓评价方法。基于物元模型和可拓关联度进行机械设计方案决策。根据专家实际经验知识建立期望设计方案的物元模型和备选设计方案的物元模型,然后通过可拓关联度直接评价方案的优劣,关联度是评价设计方案接近期望方案（理想方案）的度量,关联度越大,设计方案接近期望方案就越好。实例表明基于可拓理论的机械设计方案评价是合理的。

Assessing habitat quality for butterflies on intensively managed arable farmland

The conservation and management of biodiversity requires accurate, repeatable and cost-effective monitoring techniques. In this study, a simple and rapid methodology was employed to measure the quality of different habitats for butterfly species on 10 arable farms in lowland Britain. This habitat monitoring was seven times more rapid than the traditional species-based butterfly monitoring. Data on butterfly abundance were combined with the information gathered on habitat quality at five of the farms using stepwise regression. These models had a consistently high degree of explanatory power for the summary variables of total butterfly abundance and species richness, and the functional groupings of mobile and immobile species. There was good agreement between observed and predicted estimates of species richness and abundance when the models were validated on a further five independent sites. Models to predict the abundance of 11 common butterfly species were also produced. These varied considerably in their predictive power and validity between species. The results clearly demonstrated the beneficial effects of targeted habitat creation for butterflies which is promoted under the Agri-environment Schemes, especially the recently introduced pollen and nectar seed mixtures (WM2) available under the Countryside Stewardship Scheme. The models confirmed the importance of shelter, floristically diverse field margins and the availability of nectar resources from legume species in explaining the abundance of immobile butterfly species in arable landscapes. These sources of nectar and the presence of larval host plants in the crucifer family were important factors in explaining the abundance of mobile species. The results are discussed in terms of the potential of this approach for: (i) assessing habitat quality for butterflies in intensively managed landscapes; (ii) enhancing the value of butterfly monitoring schemes in explaining changes in butterfly abundance at the site and national scale; and (iii) informing habitat management and restoration guidelines for butterfly conservation on arable farmland.     

英国碳削减承诺能源效率体系研究及对我国的启示

英国碳削减承诺能源效率体系是以非能源密集型企业和公共机构为减排义务主体的碳排放权交易体系,在运行机制方面,以价格机制为过渡,以“首要成员”的方式确定减排义务主体,以定价出售方式实行初始配额分配;在保障机制方面,采用间接监测,实行自我认证,并设置了层次分明、形式多样的罚则.它的经验启示我国构建和完善碳排放权交易体系宜制定专项行政法规,对非能源密集型企业和公共机构适用不同的规则,构建约束有力的遵约机制.
