燃煤锅炉改造问题及节能环保改造措施

在现代社会的发展中,燃煤锅炉是工业发展中常用的供暖设备、供热设备,尤其在北方地区得到了十分广泛的应用。但是,在使用燃煤锅炉过程中,一定区域内会产生很多燃煤灰尘、SO2气体,现已成为很多地区的大气污染源之一。为了有效控制燃煤锅炉污染物排放量,相关部门需要实行烟气除尘、脱硫方式,做好燃煤锅炉节能改造工作,减少大气污染物的排放量。论文重点分析了燃煤锅炉改造问题及节能环保改造措施。

The failure of agri-environment measures to promote and conserve grassland biodiversity in Slovenia

The effectiveness of four grassland-specific agri-environment measures (AEM), implemented in the frame of the European Agricultural Fund for Rural Development (EAFRD) in the period 2007–2013 in Slovenia was studied. We questioned whether the measures – “extensive grassland maintenance”; “preservation of special grassland habitats”; “preservation of grassland habitats for butterflies” and “bird conservation in humid extensive meadows in Natura 2000 sites” did genuinely support the conservation (maintenance or improvement) of high nature value (HNV) grasslands in Slovenia. The HNV grasslands were defined on the basis of national fine-resolution field mapping of habitat types. Two main outcomes emerged: AEM did not reach the vast majority of HNV grasslands in Slovenia (only 3%); the proportion of HNV grassland area included in AEM was negligibly low (1). Moreover, even this very limited interest in AEM did not target only grasslands of HNV, but any permanent grasslands regardless of their conservation value: forty-one percent (41%) of the grassland areas included in the AEM were actually non-HNV grasslands (2). The absence of pre-selection criteria for grasslands along with an absence of monitoring of the effectiveness and efficiency of the measures and low interest in the subsidies among farmers, led to almost complete failure of the AEM to promote and conserve species-rich extensive grasslands in Slovenia between 2007 and 2013. Even with some minor differences, the same concept was maintained for the currently running EAFRD 2014–2020, which raises serious concern.     

能力导向的工程素养培养模式研究--高等工科院校教师需要“双师素质”

从我国高等工科院校“重理论、轻实践”的现状出发，提出了高等工科院校迫切需要“双师素质”教师。在明确“双师素质”内涵的前提下，提出了“双师素质”教师培养的途径和措施，即改变工科教育的教育观念与教育模式，加强工科院校教师的工程教育，引进科研院所、企业的高级工程技术人才，减轻教师的理论教学工作量加强科研实践，制定职务聘任等方面相应的配套政策。     

Assessing land use plan implementation: Bridging the performance-conformance divide

The assessment of land use plan implementation is a contentious issue. The debate centers on whether the crucial evaluation element is conformance of development to plan directives or alternatively, plan performance, i.e. the degree to which the plan is actually used. An analytic framework combining both conformance and performance in the evaluation of (regional) land use plans is applied to the case of the Central District Plan in Israel. Qualitative and quantitative simulation methods are exploited. Qualitative analysis reveals that both performance and conformance are greater than indicated by non-contextualized, numeric evaluations. Additionally, high conformance does not necessarily imply good plan performance. Quantitative simulation suggests that plan performance with respect to land values and densities is initially pronounced as expectations for development are subdued but subsequently tends to wane merging with the counterfactual trend. Findings imply that plan assessment needs to consider the transaction costs of land use re-designation and actors’ perceptions of the probability that plan amendments will be approved. These perceptions differ across actors as a function of the political influence that they wield.
