At present,China is facing rapid economic and social development as well as the shortage of land for construction. In fact,various countries and regions are faced with similar problems in the process of urbanization and industrialization,and the land readjustment is often adopted for construction land consolidation to promote economical and intensive land use and solve the supply and demand conflict of construction land. Based on the land readjustment experience of Germany,Japan,China Taiwan and South Korea,we perform a comparative analysis on the implementation background,concept,purpose,procedures and core principles,and borrow ideas from their experience,in order to provide a reference for China to adopt suitable land readjustment tools during construction land consolidation. 展开更多

As a consequence, million hectares of land exchanged hands. The ways the transfers happened combined with their geographic concentration in Sub-Saharian Africa, have earned the phenomenon the name of "land grab". The agricultural sector considered a "sunset industry" when commodities prices were declining, is now attractive to financial investors. These foreign investments may be good as they may improve agricultural productivity or instead bad as they may benefit only financial investors. Some results in terms of environmental and local communities' worsening conditions have already emerged. This paper aims to investigate what drives the big size transfers of land, to empirically estimate their effects in terms of local employment and to assess the environmental effects produced by the rapid transformation in the use of vast amount of land in terms of CO2 emissions. It is also proposed to use the estimation in terms of local employment impact as a way of distinguishing between foreign direct investment and land grabbing. 展开更多

The article seeks to examine the East Look Policy(ELP)in Iran’s Foreign Policy(IFP)(2005-2013).We believe that states,due to different factors,may adopt different policies in their FP.So,the main research question is:Why did Iranian state adopt ELP in its FP in duration of Mahmoud Ahmadinejad era?With regard to the question,our hypothesis is“there are some factors in Iran’s internal environment that we called them micro-level factors and some variable in external environment that we called them macro-level variables in formation of ELP in IFP”.To prove this hypothesis,we use James Rosenau’s foreign policy theory that has been stood on two micro-and macrolevel analysis to examination of FP of any state.Regarding Rosenau’s theory,there are four factors on micro-level include:individual of policy-maker,his/her role in political system,social values,and governmental structure.In addition,in macro-level,there are some variables,such as the logic of anarchy,the action of other states(especially US),and nuclear sanctions imposed by the US and Western nations. 展开更多

Basic situation of the current ecological environment construction in land consolidation and rehabilitation of China is introduced. The related advanced experience abroad is summarized from mainly four aspects, namely policy, system as well as subject development, planning guidance, design method of project planning and engineering study, and practical countermeasures to China's ecological environment construction in land reclamation are proposed. In terms of policy, system and subject, relevant regulations, policies and system construction should be strengthened and the framework of policy, system and subject development in ecological landscape construction of China's land reclamation should be proposed, integrating ecological environment construction into land reclamation. At the level of strategic planning, the spatial layout and construction key points of green infrastructure in land reclamation of "urban multi-functional developing region, eastern economic developed region, central modern agricultural region and northwestern ecological fragile region" should be achieved. At the level of project planning design, ecological principles, sustainable landscape design principles and vernacular landscape design methods are to be integrated into the planning procedure to form operable technique regulations or introductions. At the level of engineering design, engineering technique system, standards and regulations of ditches, roads, forests and channels with local distinctions should be formulated according to the characters and strategic demands of urbanization, industrialization, agriculture modernization and ecological environment preservation in different regions. 展开更多

Foreign body ingestion in children is considered an emergency. The most common ingested foreign bodies are coins;however, the ingestion of disc batteries is on the rise requiring urgent rigid esophagoscopy. In the literature, multiple foreign body ingestion is very rare and only a few cases of multiple coins and multiple battery ingestion have been reported in the past. Herein, a case of simultaneous coin and battery ingestion requiring foreign bodies removal on two sequential endoscopies due to improper initial evaluation in a pediatric patient is reported which, to our knowledge, is the first reported case. 展开更多
