Closing a Loop: Substance Flow Analysis of Nitrogen and Phosphorus in the Rainbow Trout Production and Domestic Consumption System in Finland

Ongoing eutrophication is changing the Baltic Sea ecosystem. Aquaculture causes relatively small-scale nutrient emissions, but local environmental impact may be considerable. We used substance flow analysis (SFA) to identify and quantify the most significant flows and stocks of nitrogen (N) and phosphorus (P) related to rainbow trout aquaculture in Finland. In 2004–2007, the input of nutrients to the system in the form of fish feed was 829 t N year⁻¹ and 115 t P year⁻¹. Around one-fifth of these nutrients ended up as food for human consumption. Of the primary input, 70% ended up in the Baltic Sea, directly from aquaculture and indirectly through waste management. The nutrient cycle could be closed partially by using local fish instead of imported fish in rainbow trout feed, thus reducing the net load of N and P to a fraction.     

工业园区低碳发展模式评估与规划分析

通过对工业园区低碳发展模式的评估,分析其低碳发展的能源特征、经济特征与人力特征,并确定工业园区二氧化碳减排的潜力能源。基于能源-碳减排(EC)、经济-能源-碳减排(EEC)和人力-经济-能源-碳减排(HEEC)三种不同情景,在未来发展的一定规划期内,对工业园区具有二氧化碳减排潜力的能源进行规划分析,确定其年递减率,从而实现工业园区不同情景下的二氧化碳减排。通过实际案例研究,证明了评估与规划分析模型的可行性。     

Assessing health impacts in complex eco-epidemiological settings in the humid tropics: Modular baseline health surveys

The quantitative assessment of health impacts has been identified as a crucial feature for realising the full potential of health impact assessment (HIA). In settings where demographic and health data are notoriously scarce, but there is a broad range of ascertainable ecological, environmental, epidemiological and socioeconomic information, a diverse toolkit of data collection strategies becomes relevant for the mainly small-area impacts of interest. We present a modular, cross-sectional baseline health survey study design, which has been developed for HIA of industrial development projects in the humid tropics. The modular nature of our toolkit allows our methodology to be readily adapted to the prevailing eco-epidemiological characteristics of a given project setting. Central to our design is a broad set of key performance indicators, covering a multiplicity of health outcomes and determinants at different levels and scales. We present experience and key findings from our modular baseline health survey methodology employed in 14 selected sentinel sites within an iron ore mining project in the Republic of Guinea. We argue that our methodology is a generic example of rapid evidence assembly in difficult-to-reach localities, where improvement of the predictive validity of the assessment and establishment of a benchmark for longitudinal monitoring of project impacts and mitigation efforts is needed.     

我国资源型企业对外直接投资区位选择研究——以铁矿企业为例

世界铁矿资源分布不均匀，导致世界各国对铁矿资源的争夺非常激烈。在资源所在国直接投资是获取铁矿资源的主要方式之一，而投资区位选择又直接关系到铁矿企业与企业所在国对外直接投资的成败。分析了我国铁矿企业对外直接投资现状，指出了其存在的问题，探讨了铁矿资源丰富国家的投资环境，对我国铁矿企业对外直接投资风险的影响，并对我国铁矿企业的对外投资区位选择提出了建议。     

企业生产安全事故的“基因”分析

思索生产安全事故频发共性表象"违法、违章"背后的原因,提出"生产安全事故基因"概念。分析得出"去小概率性"、"社会责任缺失"和"非货币化产出分析能力短缺"3种生产安全事故基因,前两种基因是不可去基因,后一种是可去基因,三者会在不同的条件下以显性或隐性的形式呈现,并作用于生产过程;提出企业组织安全进化的常规对策——完善市场经济环境,创新对策——教育要为"安全"生产服务,强调学历教育系统在创新对策中的重要地位和作用。通过"基因"分析及其对策,为安全生产培养安全管理人员和相关人才,推动安全生产,实现经济与社会和谐发展。     

2008年我国环境保护投资总体特征分析

立足于环保投资数据库,从投资构成、空间分布和行业分布3个方面对我国环保投资进行综合分析。2008年,全国环保投资增幅持续保持较快增长,环保投资弹性系数为1.9,环保投资增速大大超过经济增速,"三同时"项目成为拉动环保投资的主要驱动力。引入了环保投资平衡度的概念,在此基础上对各地区环保投资的合理性进行了初步分析。重点行业环保投资方面,工业治污设施运行费用远远大于同期固定资产投资,一定程度上说明了应对治污运行费用来源给予充分重视,采取措施确保稳定可靠的资金渠道。     

工业类建设项目验收技术规范编制内容探讨

简述了我国建设项目环保验收技术规范颁布实施,以及国外对建设项目实行全过程监管方式现状,指出现行环保验收技术规范在行业性内容、验收监测频次、质量控制措施、总量核算方面存在的问题,提出,应出台总工业类环保验收技术规范,对出台行业类验收技术规范严格把关,并加大验收技术科研力度的建议.     

乡镇工业企业的职业安全卫生工作亟待加强管理

说明目前乡镇工业企业中职业安全卫生问题十分突出。据调查，厂矿工伤事故发生率为８．２３％，每千名职工的工伤发生率为２．６６人，每十万名职工的工伤死亡率为７．０２人。通过对事故的原因进行分析，提出了加强监督管理的建议。     

‘The good district’: Newbury as a seed‐bed for success

This study analyses the behaviour of high technology and new firms in the Newbury District of Berkshire in terms of employment, location, genealogy, and local economic impact. It finds that encouraged by good communications networks and a ‘resident electronics establishment’, the direct, as opposed to the indirect, employment consequences are generally encouraging, but not widely replicable. Moreover, the general picture of employment growth masks important differences in labour demand across occupations, particularly with respect to ‘traditional male’ skilled manual workers.     

Will science parks generate the fifth wave?

The paper examines characteristics of science parks in the face of employment decline, raising doubts about the scale of their success. The paper re‐examines previous research on the existence and causes of long waves of economic growth and decline and concludes that if these are not generated by innovations in production, then it should not be surprising that science parks have not lived up to expectations.
