[Method] The research was made by comparison, according to the development impetus. [Result] The results show that foreign agricultural informatization is mainly divided into three categories： the first category is the government leading; the second category is the industry self-help; the third category is typical demonstration. Since the reform and opening, Chinese agricultural informatization has made considerable achievements. [Conclusion] The agricultural informatization is significant to promote the update of the traditional agriculture, and it is also essential to Chinese agricultural sustainability.展开更多
The present paper discusses the typical problems in a C-E translation exercise by non-English-major postgraduates. It concludes by providing some implications to translation teaching and learning.

Based on some influential definitions, and achievements made in sociology and anthropology, this paper makes an attempt to summarize and discuss some characteristics of culture. With regard to the categorization of culture, we put forward the idea that it is closely related to the definition and features of culture, and also that it is closely related with human cognition and different perspectives, and thus culture category is an open system just as culture in general. Cultural development as product of human evolution and development is both a need and reality, going on through cultural transmission. In the process, it is human nature to encounter cultural conflicts like culture shock, the solution of which partially depends on cultural studies, on a close relationship with the main school of culture or dominating culture and on seeking similarities and accepting differences, and in a word, on friendly and cordial contacts and understanding through linguistic communication.展开更多

The task assignment problem in HC environment can be formally defined as for a given set of tasks and machines, assigning tasks to machines to achieve the minimum makespan. In this paper we propose a new task scheduling heuristic, high standard deviation first (HSTDF), which considers the standard deviation of the expected execution time of a task as a selection criterion. Standard deviation of the ex- pected execution time of a task represents the amount of variation in task execution time on different machines. Our conclusion is that tasks having high standard deviation must be assigned first for scheduling. A large number of experiments were carried out to check the effectiveness of the proposed heuristic in different scenarios, and the comparison with the existing heuristics (Max-min, Sufferage, Segmented Min-average, Segmented Min-min, and Segmented Max-min) clearly reveals that the proposed heuristic outperforms all existing heuristics in terms of average makespan.展开更多
