安全生产工作体制思考

一个切合实际特点、设置科学合理、责权界定清晰、运行顺畅有效的安全生产工作体制是发挥各方作用、共同做好安全工作的基础和前提。从安全生产工作体制的基本内涵出发,回顾了我国不同时期国情特点下的安全生产工作体制。针对当前国情特点和安全生产工作体制状况进行了分析,指出监督（察）与管理是一对矛盾,两种职能由同一部门行使不合理,应当分开,国家监察职责不宜分散而应集中,以减少执法成本和企业负担,并且要加强中介机构、非政府组织（NGO）和第四权力―媒体的作用的观点,提出了当前安全生产工作体制的新思考。     

National Red Listing Beyond the 2010 Target

Abstract: Following creation of the 2010 Biodiversity Target under the Convention on Biological Diversity and adoption of the United Nations Millennium Development Goals, information on status and trends of biodiversity at the national level has become increasingly important to both science and policy. National red lists (NRLs) of threatened species may provide suitable data for reporting on progress toward these goals and for informing national conservation priority setting. This information will also become increasingly important for developing species‐ and ecosystem‐based strategies for climate change adaptation. We conducted a thorough global review of NRLs in 109 countries and analyzed gaps in NRL coverage in terms of geography and taxonomy to determine priority regions and taxonomic groups for further investment. We then examined correlations between the NRL data set and gross domestic product (GDP) and vertebrate species richness. The largest geographic gap was in Oceania, followed by middle Africa, the Caribbean, and western Africa, whereas the largest taxonomic gaps were for invertebrates, fungi, and lichens. The comprehensiveness of NRL coverage within a given country was positively correlated with GDP and negatively correlated with total vertebrate richness and threatened vertebrate richness. This supports the assertion that regions with the greatest and most vulnerable biodiversity receive the least conservation attention and indicates that financial resources may be an integral limitation. To improve coverage of NRLs, we propose a combination of projects that target underrepresented taxa or regions and projects that provide the means for countries to create or update NRLs on their own. We recommend improvements in knowledge transfer within and across regions as a priority for future investment.     

Psychosocial and Ergonomic Factors,and Their Relation to Musculoskeletal Complaints in the Swedish Workforce

A random sample of 1 000 subjects (20–65 years old) from the national population of Sweden received a questionnaire; 70% (n = 695) replied, of whom 532 were occupationally active. Female gender, working with neck and/or body bent forward, arms above shoulders, and precision work tasks were predictors of musculoskeletal symptoms. Neck, shoulder, and upper back symptoms were more common in a strained situation at work (high demands, low control) (adjusted odds ratios [adjOR] 2.76, 2.80, and 2.26, respectively). Among females, neck and shoulder symptoms were more common in an iso-strain situation (high demands, low control and low social support) (adjOR 4.43 and 3.69, respectively), and low back symptoms were more common at low social support combined with a passive work situation (adjOR 3.35). No associations were found between iso-strain model and symptoms among males. In conclusion, iso-strain work situation was associated with neck symptoms among females, even when controlling for ergonomic factors.     

Development and Application of an Agricultural Intensity Index to Invertebrate and Algal Metrics from Streams at Two Scales

Research was conducted at 28‐30 sites within eight study areas across the United States along a gradient of nutrient enrichment/agricultural land use between 2003 and 2007. Objectives were to test the application of an agricultural intensity index (AG‐Index) and compare among various invertebrate and algal metrics to determine indicators of nutrient enrichment nationally and within three regions. The agricultural index was based on total nitrogen and phosphorus input to the watershed, percent watershed agriculture, and percent riparian agriculture. Among data sources, agriculture within riparian zone showed significant differences among values generated from remote sensing or from higher resolution orthophotography; median values dropped significantly when estimated by orthophotography. Percent agriculture in the watershed consistently had lower correlations to invertebrate and algal metrics than the developed AG‐Index across all regions. Percent agriculture showed fewer pairwise comparisons that were significant than the same comparisons using the AG‐Index. Highest correlations to the AG‐Index regionally were ?0.75 for Ephemeroptera, Plecoptera, and Trichoptera richness (EPTR) and ?0.70 for algae Observed/Expected (O/E), nationally the highest was ?0.43 for EPTR vs. total nitrogen and ?0.62 for algae O/E vs. AG‐Index. Results suggest that analysis of metrics at national scale can often detect large differences in disturbance, but more detail and specificity is obtained by analyzing data at regional scales.     

重点生态功能区生态资产保护成效及驱动力研究

重点生态功能区是保障国家生态安全、扩大绿色生态空间的重要区域,在实现全国生态资产保值增值方面发挥着重要作用。然而,现阶段围绕重点生态功能区生态资产保护成效及驱动力开展的研究较少。为明确重点生态功能区生态资产保护的驱动力以及存在的问题,本文利用遥感影像并结合图像解译、GIS空间分析和数理统计等方法对重点生态功能区内生态资产展开分析,并将其与非重点生态功能区进行比较。研究结果显示:重点生态功能区内森林、灌丛、草地和湿地生态资产总面积为349.30万km~2,优级和良级生态资产占生态资产总面积的42.42%,生态资产综合指数为21.19。15年间,重点功能区内生态资产总面积增加0.05%,优级和良级生态资产面积占比分别增加0.59%和0.85%,生态资产综合指数增加2.94。重点生态功能区生态资产面积和质量增幅均小于非重点生态功能区,然而重点生态功能区生态资产指数增量高于非重点生态功能区。生态恢复是驱动重点生态功能区生态资产面积变化的主因,对原有生态资产的保护是促进生态资产指数增加的最主要驱动力(贡献率达81%),城镇化和农业开发对生态资产的不利影响不容忽视(贡献率达-6.81%)。研究表明,对重点生态功能区生态资产保护成效显著,同时还有较大提升空间。本研究也为优化重点生态功能区的城镇化和农业开发的管理提供了证据和参考。     

历史性转变——20o6中国环境保护评述

2006年,从中央到地方都大幅度强化了环境保护的施政力度。中央提出了环境保护与经济增长要并重、同步和综合的要求,这被称为“环境保护的历史性转变”。与此同时,国家出台了20多项以环境保护为重要内容或与环境保护有关的产业政策和其他经济政策。新成立了11个环境保护和核安全的区域督查机构,层层下达了主要污染物排放消减指标。各地也把主要精力放在了推动新型工业化和城市化进程上,出台了大量加强和支持环境保护的经济政策和管理措施。     

国家资源安全及其系统分析

论尊重国家主权和不损害管辖范围以外环境原则

尊重国家主权和不损害管辖范围以外环境原则发轫于环境问题对国家主权提出的挑战,目的是为了在对国家主权予以确认和维护的同时,对其进行适当限制,以避免国家主权的行使危及管辖范围以外环境.该原则的重要性已经为学界所公认,其作为对环境与主权关系之争论的回应,法理基础是建立在国家主权原则、互相尊重主权、禁止权利滥用原则、全球共同利益与可持续发展的理念之上的.尊重国家主权和不损害国外环境原则是对国际环境法主体的权利、义务与责任进行调整.     

农民工参加工伤保险的影响因素研究——基于政策和企业视角的实证分析

为了解我国农民工参加工伤保险的影响因素,提高农民工工伤保险的参保率,通过对全国9个省市共3 848名农民工的问卷调查,应用Logistic回归模型分析政策的因素和企业的因素对农民工参加工伤保险的影响。结果表明,农民工是否参加工伤保险受到各地工伤保险政策以及农民工所在企业两方面的影响。从政策的角度看,个体工商户参加工伤保险的规定、工伤保险基金的统筹水平以及工伤保险的偿付方式对农民工参加工伤保险有显著影响;从企业的角度看,农民工所在企业是否建有工会、企业所有制对农民工参加工伤保险有显著影响。建议各地进一步明确工伤保险政策中对个体工商户的参保要求,继续提高工伤保险基金的统筹水平,增加农民工领取工伤保险偿付的方式。建议劳动保障部门加强对未建有工会的企业,加强对私企,特别是个体工商户的监察力度。     

Forests in common: Learning from diversity of community forest arrangements in Europe

Europe has a wealth of community forest arrangements. This paper aims to transcend the diversity of locally specific terms and forms, to highlight the value of considering them inclusively. Building on methods to make sense of diversity, we use reflexive grounded inquiry in fifteen cases in Italy, Scotland, Slovenia and Sweden. Within four dimensions (forest, community, relationships between them, and relationships with wider society), we identify 43 subdimensions to describe them collectively. Our approach shows how European arrangements contribute to wider discourses of collective natural resource management. Both tradition and innovation in Europe inform options for environmental governance. Arrangements challenge the distinction between ‘communities of place’ and ‘communities of interest’, with implications for social and environmental justice. They exemplify multilevel environmental governance through both vertical and horizontal connections. Emerging from long histories of political and environmental pressures, they have a role in enhancing society’s connection with nature and adaptive capacity.Electronic supplementary materialThe online version of this article (10.1007/s13280-020-01377-x) contains supplementary material, which is available to authorised users.
