非法用工单位伤亡人员一次性赔偿程序的探讨

2004年1月1日生效的《工伤保险条例》规定了非法用工单位向伤亡人员赔偿的标准和争议解决的程序，但是非法用工单位不属于法律上合法的主体，劳动仲裁机关和法院不能对不存在的主体作出裁定和判决，就算作出裁判，也不可能得到执行，从而使得该条例规定的对非法用工单位伤亡人员的赔偿成为一纸空文。为此，笔者从劳动争议和诉讼主体认定，程序保障和伤亡人员及时得到救助三个方面提出建议，以确保条例得到执行。     

ACCURACY OF LAKE AND STREAM TEMPERATURES ESTIMATED FROM THERMAL INFRARED IMAGES1

Emitted thermal infrared radiation (TIR, λ= 8 to 14 μm) can be used to measure surface water temperatures (top approximately 100 μm). This study evaluates the accuracy of stream (50 to 500 m wide) and lake (300 to 5,000 m wide) radiant temperatures (15 to 22°C) derived from airborne (MASTER, 5 to 15 m) and satellite (ASTER 90 m, Landsat ETM+ 60 m) TIR images. Applied atmospheric compensations changed water temperatures by ?0.2 to +2.0°C. Atmospheric compensation depended primarily on atmospheric water vapor and temperature, sensor viewing geometry, and water temperature. Agreement between multiple TIR bands (MASTER ‐ 10 bands, ASTER ‐ 5 bands) provided an independent check on recovered temperatures. Compensations improved agreement between image and in situ surface temperatures (from 2.0 to 1.1°C average deviation); however, compensations did not improve agreement between river image temperatures and loggers installed at the stream bed (from 0.6 to 1.6°C average deviation). Analysis of field temperatures suggests that vertical thermal stratification may have caused a systematic difference between instream gage temperatures and corrected image temperatures. As a result, agreement between image temperatures and instream temperatures did not imply that accurate TIR temperatures were recovered. Based on these analyses, practical accuracies for corrected TIR lake and stream surface temperatures are around 1°C.     

基于生态足迹的武汉城市圈生态承载力评价和生态补偿研究

在推进新型城镇化和生态建设的背景下,客观定量评价区域生态环境状态,是当前我国生态建设重要而紧迫的任务之一。高密度的人类活动会对自然生态系统产生超负荷的压力,通过生态承载力的分析能够定量测度这种状况,为区域可持续发展提供借鉴意义。基于生态足迹模型,计算了2008年和2013年武汉城市圈各县域单元的生态足迹/承载力,并进行了时空变化分析。研究发现武汉城市圈各县域单元的生态足迹和生态承载力在空间上存在显著的差异性,生态足迹逐年增加,生态承载力的变化相对较小,出现两级分化的现象。根据生态足迹/承载力进行跨区县生态补偿测算,得到2008年和2013年武汉城市圈48个县域的转移支付情况,表明如果运用财政转移支付的手段,整个区域能够达到生态系统供给和需求动态平衡的目标,缓解武汉城市圈的生态压力,实现武汉城市圈的可持续发展。     

Landscape consequences of aggregation rules for functional equivalence in compensatory mitigation programs

Mitigation and offset programs designed to compensate for ecosystem function losses due to development must balance losses from affected ecosystems with gains in restored ecosystems. Aggregation rules applied to ecosystem functions to assess site equivalence are based on implicit assumptions about the substitutability of functions among sites and can profoundly influence the distribution of restored ecosystem functions on the landscape. We investigated the consequences of rules applied to the aggregation of ecosystem functions for wetland offsets in the Beaverhill watershed in Alberta, Canada. We considered the fate of 3 ecosystem functions: hydrology, water purification, and biodiversity. We set up an affect‐and‐offset algorithm to simulate the effect of aggregation rules on ecosystem function for wetland offsets. Cobenefits and trade‐offs among functions and the constraints posed by the quantity and quality of restorable sites resulted in a redistribution of functions between affected and offset wetlands. Hydrology and water purification functions were positively correlated with one another and negatively correlated with biodiversity function. Weighted‐average rules did not replace functions in proportion to their weights. Rules prioritizing biodiversity function led to more monofunctional wetlands and landscapes. The minimum rule, for which the wetland score was equal to the worst performing function, promoted multifunctional wetlands and landscapes. The maximum rule, for which the wetland score was equal to the best performing function, promoted monofunctional wetlands and multifunctional landscapes. Because of implicit trade‐offs among ecosystem functions, no‐net‐loss objectives for multiple functions should be constructed within a landscape context. Based on our results, we suggest criteria for the design of aggregation rules for no net loss of ecosystem functions within a landscape context include the concepts of substitutability, cobenefits and trade‐offs, landscape constraints, heterogeneity, and the precautionary principle.     

Framing of Geoengineering Affects Support for Climate Change Mitigation

The growing recognition that climate change mitigation alone will be inadequate has led scientists and policymakers to discuss climate geoengineering. An experiment with a US sample found, contrary to previous research, that reading about geoengineering did not reduce conservatives’ skepticism about the existence of anthropogenic climate change. Moreover, depending on how it is framed, geoengineering can reduce support for mitigation among both conservatives and non-conservatives. When geoengineering is framed as a major solution, people worry less about climate change, leading to reduced mitigation support. When framed as disastrous, people perceived geoengineering as riskier, also leading to a decrease in mitigation support. A more moderate framing of geoengineering as a partial solution is less susceptible to moral hazard effects. Overall, results suggest that geoengineering will not lessen political polarization over anthropogenic climate change, and could undercut support for mitigation efforts. Instead, framing geoengineering as a small piece to solving a big puzzle seems to be the best strategy to weaken this potential moral hazard.     

环境司法专门化下的特殊环境诉讼规则

我国的环境司法处于发展初期,有关环境纠纷的司法救济程序散落在不同的部门法中。为了维护国家环境安全和公共环境利益,构建环境司法专门化势在必行,但是在特殊的环境保护法院进行专门化的环境审判过程中,出现环境诉讼保护对象的争议性、生态环境损害责任承担的特殊性等问题亟待解决,环境民事公益诉讼和生态环境损害赔偿诉讼等特殊环境诉讼规则应运而生,虽然目前还面临着一些困境,但是整体上构建环境司法体系的进程依然在不断推进。     

农地整理项目农户耕地损失补偿额度的实证研究——基于耕地资源价值与农户受偿意愿

从耕地资源价值出发,测算农地整理项目农户耕地损失补偿额度,并基于湖北省孝感市和潜江市的农户调查数据分析农户的受偿意愿及其影响因素。研究表明:基于耕地资源价值体系,测算得到孝感市和潜江市农地整理项目农户耕地损失补偿额度分别为1 449 695.76、1 784 296.17元/hm~2;农户所期望得到的耕地损失补偿标准远低于耕地资源价值体系测算出来的理论值,两市农户对耕地损失的平均受偿意愿额度为336 197.95元/hm~2,可以农户受偿意愿为主、耕地农业生产价值和社会保障价值为辅,制定农地整理项目农户耕地损失补偿标准;受教育程度对补偿标准有显著负向影响,农户文化程度的提高有助于提高其对农地整理事业的认知程度,进而促进我国农地整理事业的发展;土地权属调整是解决农户耕地损失的一项重要措施,做好农地整理项目土地权属调整工作需充分尊重农户的意愿,并以农业现代化作为土地权属调整的目标。     

Connotation and principles of ecological compensation in water source reserve areas based on the theory of externality

Understanding the connotation and principles of ecological compensation in water source reserve areas is the basis and guarantee for establishing and improving the ecological compensation mechanism of water source reserve areas. First, this paper reviews the three stages of ecological compensation research progress. Based on the review, using the theory of externality, the ecological environment system of water source reserve areas is then analyzed. This paper argues that the connotation of ecological compensation in water source reserve areas is a kind of institutional arrangement, which is designed to internalize externalities. Finally, based on the understanding of the connotation of ecological compensation in water source reserve areas, five principles for establishing and improving the ecological compensation mechanism are proposed, including the principle of fairness and justice, the principle of equivalence of equality and responsibility, the principle of flexibility and effectiveness, the principle of “earmark funds, and implementation by law,” and the principle of government compensation supplemented with market compensation.     

家庭农场土地征收补偿问题研究

随着未来家庭农场数量的逐渐增加与经营土地面积的不断扩大,与快速城镇化相伴随的土地征收区域不可避免会与家庭农场经营的土地范围相交叉或重叠。家庭农场主通过整合作为集体经济组织成员分得的承包地和市场化交易获得的承包地实现土地适度规模经营,因此,在家庭农场土地被征收时,应确保家庭农场主获得科学合理的补偿标准,并妥善处理家庭农场主与拥有不同类型农地权利的众多相关主体之间的利益分配关系。本文采用文献资料法和理论分析法,区分点状征地、线状征地和面状征地三种不同情况,分析了家庭农场土地征收的后期生产经营影响,在土地承包关系"长久不变"的政策框架下,深入剖析了家庭农场土地征收涉及的农地权利类型。然后,构建起家庭农场土地征收补偿标准理论模型,以及家庭农场主、政府、集体经济组织、农民等权利主体之间的收益分配理论模型。具体而言,家庭农场主根据自有土地、通过土地流转获得的土地、通过土地退出获得的土地所占的比重以及不同类型土地权利所对应的价值标准分得相应的征地补偿收益;政府通过税收参与征地补偿收益分配;集体经济组织凭借土地所有者身份依法分得相应比例的补偿收益;农民获得的征地补偿收益为承包经营权价值扣除其让渡给家庭农场主的农地权利价值后的剩余部分。最后,本文从四个方面提出了相应的对策和建议:1做好家庭农场发展规划;2提高征地补偿标准并将间接损失纳入补偿范围;3建立家庭农场规模化经营土地的征收补偿收益分配机制;4保障抵押权人(金融机构)对征地补偿享有优先受偿权。
