The Eurasian Economic Union: Development Prospects and Possible Obstacles

This article analyzes the development prospects and problems for the Eurasian Economic Union (EAEU). It examines issues of integration within the EAEU, as well as interactions with other countries, both CIS (Commonwealth of Independent States) and non-CIS. The main problem of integration within the EAEU is the dominance of redistributive motives over productive ones. This article assesses the extent of Russian oil and gas transfers to EAEU partners and the impact of tax maneuvers on their size. It shows that the creation of mechanisms for redistributing profits within the EAEU will allow a positive economic effect to materialize from free trade agreements with non-CIS countries. The article assesses the risks for the EAEU related to Russia’s introduction of a unilateral ban on food imports from countries on the sanctions list and to the possible establishment of tariffs on trade with Ukraine.     

Fire and restoration of the largest urban forest of the world in Rio de Janeiro City,Brazil

National Park of Tijuca in Rio de Janeiro (Brazil) is about 3,300 ha and considered the largest urban forest in the world. Its floristic composition is typical of Atlantic Rain Forest. The reserve is being altered because of fire occurrences and urban expansion. This study identified locations and causes of forest fires, and makes management recommendations to restore damaged areas. From 1991 to 2000, forest firefighters recorded an average of 75-fire occurrences/year. Identified causes included hot air balloons (24%), intentional (24%), rubbish burning (21%) and religious practices (17%). Primary fuels included invasive grasses and ferns. Although hot air balloons destroyed larger areas of forest in each occurrence, a greater number of fires started in the invasive vegetation along roads that bisect the forest. In response to recurrent forests, invasive vegetation has spread gradually into the forest increasing forest degradation. To decrease fire damage, sites with high fire frequencies and density of invasive vegetation were planted with less flammable species. Results indicate that fire frequency decreased and density of invasive vegetation declined. This approach appears to prevent fire incidence, reduce the need for fire fighting, and preserve existing biodiversity.     

The potential of integrated modelling in conservation biology: A case study of the black‐footed albatross (Phoebastria nigripes)

Conservation biology aims at assessing the status of a population, based on information which is often incomplete. Integrated population modelling based on state‐space models appears to be a powerful and relevant way of combining into a single likelihood several types of information such as capture‐recapture data and population surveys. In this paper, the authors describe the principles of integrated population modelling and they evaluate its performance for conservation biology based on a case study, that of the black‐footed albatross, a northern Pacific albatross species suspected to be impacted by longline fishing

近百年来中国对文物建筑与历史地段的保护

论文以1949年为界,分两大部分叙述了迄今为止大约100年来中国对文物建筑与历史地段的保护。总结出1949年后中国近代文物建筑保护思想观念的演变特征,即前期以具有社会主义特色的保护观念为主,80年代以来发展为逐渐与国际接轨。     

高新技术园区自主创新能力与可持续发展问题研究

建设创新型园区是当前和今后一个时期落实建设创新型国家战略目标的一个重要内容。推进创新型园区建设应以园区社会可持续发展为前提，力求在“全面、协调、可持续”发展的基础上，加快提高自主创新能力。     

关于“建设生态文明”提出的依据及实现的途径

党的十七大适应国内外形势的新变化，顺应各族人民过上更好生活的新期待，提出了实现全面建设小康社会奋斗目标的新要求，并首次将“建设生态文明”写入报告，这是我们党科学发展、和谐发展理念的一次升华。而探讨生态文明形成的理论依据、现实依据以及建设生态文明的实现途径，对理解和落实十七大报告具有一定的借鉴作用。     

开发区类企业的企业化博弈演进分析

基于我国开发区发展瓶颈现象和一个动态博弈模型，指出开发区类企业所具有的特殊的企业形态．该类企业在开发区初创阶段，以完成政府的效用为其义务．政府在开发区发展的各个阶段，其效用函数是不同的．当政府的期望效用基本完成之后，就应当逐渐退出其行政控制．由于政府的政绩诉求和权威惯性，其行政控制的退出往往比较迟缓．通过开发区类企业与政府的利益博弈，开发区类企业逐步完成其纯企业化的过程．这种博弈引发的交易成本可能使得开发区类企业的纯企业化过程时间过长，从而导致整个过程的非效率性．     

能源教育：节约型社会建设的重要途径

节约型社会建设目标的提出,进一步对节能工作提出了挑战。加强节约型社会建设和提高节能工作的效果,从国外经验来看,能源教育是一个现实和有效的途径。本文从能源教育的必要性及国外能源教育的经验入手,提出了中国发展能源教育的若干建议。
