核能发展:步履艰难中拓展无限空间

福岛核泄漏事故之后,国务院常务会议慎重重启核电建设步伐,核能仍然是我国能源战略的重要组成部分。发展核能是从环境保护、经济发展、政治稳定等诸多因素综合考虑的结果,是时代的必然选择。现阶段,稳步有序推进核能正常发展;确保安全第一,是核能发展的必备条件和基础保障;积极开展技术革新,为核能发展拓展无限空间。     

The many faces of accessibility: engineers' perception of information sources

Numerous studies of engineers' information seeking behavior have found that accessibility was the factor that influenced most their selection of information sources. The concept of accessibility, however, is ambiguous and was given various interpretations by both researchers and engineers. Detailed interviews with 32 engineers, in which they described incidents of personal information seeking in depth, uncovered some of the specific factors that are part of the concept. Engineers selected sources because they had the right format, the right level of detail, a lot of information in one place, as well as for other reasons. When looking for human information resources, the engineers most frequently selected sources with which they were familiar, while saving time was the most frequently mentioned reason for selecting documentary sources. Future research should continue to examine the concept of accessibility through detailed empirical investigations.
