According to the results,(1) corn production cost in China is the highest among these three countries;(2) the rapid growth of labor cost and land cost is the major factor that promotes the increase of total corn production cost in China;(3) the level of agricultural mechanization in China has been gradually improving, and the gap between agricultural mechanization levels in China and other two countries is constantly narrowing;(4) differing from the U.S. and Brazil,China exhibits a "high input, low output" agricultural production mode. Based on the above analyses, corresponding suggestions have been presented to reduce corn production cost in China.展开更多

This is further exacerbated by the fact that most passenger rail services operate on corridors that are shared with freight traffic. A capacity analysis is one alternative to address the situation and there are various approaches, tools, and methodologies available for application. As the U.S. continues to develop higher speed passenger services with similar characteristics to those in European shared-use lines, understanding the common methods and tools used on both continents grows in relevance. There has not as yet been a detailed investigation as to how each continent approaches capacity analysis, and whether any benefits could be gained from cross-pollination. This paper utilizes more than 50 past capacity studies from the U.S. and Europe to describe the different railroad capacity defini- tions and approaches, and then categorizes them, based on each approach. The capacity methods are commonly di- vided into analytical and simulation methods, but this paper also introduces a third, "combined simulation- analytical" category. The paper concludes that Europeanrail studies are more unified in terms of capacity, concepts, and techniques, while the U.S. studies represent a greater variation in methods, tools, and objectives. The majority of studies on both continents use either simulation or a combined simulation-analytical approach. However, due to the significant differences between operating philosophy and network characteristics of these two rail systems, European studies tend to use timetable-based simulation tools as opposed to the non-timetable-based tools commonly used in the U.S. rail networks. It was also found that validation of studies against actual operations was not typically completed or was limited to comparisons with a base model.展开更多

A qualitative content analysis in which data (the academic papers) are coded in preparation for comparison and interpretation is chosen to find the similarities and differences of smart grid development in different national contexts. Trough a comparative analysis of the smart grid development in USA, Europe and China, this paper conducts a transferable framework of smart grid solution with global and local features.展开更多

While the effort made by the returnees and the Communist regime has been studied, the role played by the U.S. government remains unclear. Relying mostly on archived government documents and published individual recollections, this paper shows that Washington provided most of its assistance to the Chinese students through the emergency aid program, which not only covered all the educational costs for about three quarters of them, but also paid travel expenses for about two thirds of the returnees. In addition, Washington assisted many students in obtaining visas from the British government for their transfer in Hong Kong and offered them room, board, and other services while they were waiting for their transportation in San Francisco. The examination of the helping hand extended by Washington to these returning Chinese students can enhance our understanding of the complex and dynamic nature of Sino-American relations during the Cold War.展开更多
