金融危机下民营制造业可持续发展路径与政府责任

制造业仍然是中国国民经济的支柱产业.金融危机对外向型的中国制造业造成了严重的冲击,应对危机的根本途径是在提高国际竞争力和承担社会责任之间取得平衡,走可持续发展道路.在中国制造业中,民营企业已经占据主体地位,但是国际竞争力并不强.增强民营制造业企业的国际竞争力是我国制造业乃至整个国民经济摆脱困境的必然选择.目前,我国民营制造企业虽有一定发展,但总体上还处于国际分工价值链的低端,"硬竞争力"和"软竞争力"都明显不足,既受到技术、资金的硬件限制,又没有形成优秀的品牌和企业文化.要提高其国际竞争力,既取决于民营制造企业自身的努力,又要靠政府提供有利的发展环境.民营制造业企业要自主创新、以质取胜、加强管理,并且要增加社会责任感.政府需要在准入条件、融资环境和税收环境方面提供支持.     

Seasonal variation of organochlorine contaminants in bonito (Sarda sarda L. 1758) and anchovy (Engraulis encrasicolus L. 1758) in Black Sea region, Turkey

The concentrations of indicator polychlorinated biphenyls (PCBs) and organochlorine insecticides were determined in bonito (Sardasarda L. 1758) and anchovy (Engraulisencrasicolus L. 1758) from the Black Sea, Turkey. Concentrations of total indicator PCBs ranged between <1-17.0 in bonito, and <1-17.5 ng/g fresh weight in anchovy, and total of 1,1,1-trichloro-2,2-bis-chlorophenyl-ethane and its metabolites’ (DDTs) concentrations ranged between 13.4-26.3, and 2.96-19.0 ng/g fresh weight in bonito and anchovy respectively. PCB 52, p,p′-DDE and endosulfan (α + β) were found dominant in both of the fish species. Except endosulfan, and some DDT metabolites, none of the studied organochlorine pesticides was detected in the fish samples. Concentrations of PCBs in anchovy were found higher than those in bonito, whereas DDT and endosulfan concentrations were found similar in both of the fish species. All of the fish samples had residue concentrations below the maximum residue limits (MRL) recommended by FAO/WHO Codex Alimentarius Commission.     

借鉴国际经验助推我国汞污染场地修复

汞污染问题已经成为国内外关注的环境热点问题。我国是汞的生产、使用和排放大国,涉汞行业众多,汞污染场地问题突出。发达国家在汞污染场地治理方面有着丰富的经验。本文通过借鉴美国和英国的相关经验,从完善法规标准、健全管理制度、增强科技支撑和完善投融资政策四个方面为我国未来开展汞污染场地修复工作提出政策建议。     

中国与欧盟的航空安全信息分类法比较

为探讨中国和欧盟政府间进行航空安全信息交换的可行性,从中国和欧盟各自航空安全信息系统的信息结构和报告内容出发,对中国和欧盟的航空安全信息分类法进行比较。结果表明,两个分类法的信息结构是相同的,不同之处在于主题差异、部分差异和属性差异。笔者认为,虽然存在3种差异,但两个分类法都是基于国际民航组织航空安全信息分类法设计的,信息报告内容具有很大的相似性,因此,从信息内容上看,中欧进行航空安全信息交换是可行的。同时,对如何改进我国航空安全信息分类法提出了建议。     

国际环境制度对能源安全战略的重大影响

能源安全一直是国际政治和经济领域的重大问题。在追求可持续发展和全球化不断推进的2l世纪,国际环境制度的逐步形成为能源安全赋予了新的涵义,生态安全已经成为能源安全的重要组成部分。以保障能源供应为主要出发点的传统能源安全观逐渐向着涵盖能源供应、经济竞争力和环境质量三大要素的“综合能源安全观”的方向发展。

Proliferating Principles; Or How to Sup with the Devil without Getting Eaten

The international humanitarian system is seen by many to be in crisis. The reasons for this are complex but include the perception held by many that there is an increasing ambivalence on the part of powerful states to invest military, political and financial resources in upholding humanitarian principles, and a growing feeling that much humanitarian action both ignores human rights issues and can prolong conflict. As a result, much attention has focused on the notion of 'humanitarian principles' and there has been a proliferation of statements and initiatives on this topic in recent years.     

Establishing the link between ammonia emission control and measurements of reduced nitrogen concentrations and deposition

In the context of international efforts to reduce the impactsof atmospheric NH₃ and NH₄ ⁺ (collectively, NH_x), it is important to establish the link between NH₃emissions and monitoring of NH_x concentrations and deposition. This is equally relevant to situations where NH₃emissions changes are certain (e.g. due to changed source sectoractivity), as to cases where NH₃ abatement technologies havebeen implemented. Correct interpretation of adequate atmosphericmeasurements is essential, since monitoring data provide the onlymeans to evaluate trends in regional NH₃ emissions.These issues have been reviewed using available measurements and modelling from nine countries. In addition to historic datasets,the analysis here considers countries where NH₃ source sector activity changed (both increases and decreases) and countries where NH₃ abatement policies have been implemented.In The Netherlands an `ammonia gap' was identified between the expected reduction and results of monitoring, and was attributedinitially to ineffectiveness of the abatement measures. The analysis here for a range of countries shows that atmospheric interactions complicate the expected changes, particularly sinceSO₂ emissions have decreased at the same time, while at manysites the few years of available data show substantial inter-annual variation. It is concluded that networks need to beestablished that speciate between NH₃ and aerosol NH₄ ⁺, in addition to providing wet deposition, and sample at sufficient sites for robust regional estimates to be established. Such measurements will be essential to monitor compliance of the international agreements on NH₃ emission abatement.
