Medicine has made increasing use of meta-analysis, largely as a quantitative procedure for combining results of clinical trials. Meta-analysis begins with a comprehensive review of the literature. The next step is a systematic analysis of the quality and content of each study. Finally, results are combined statistically and conclusions are drawn from this new overview of the data. This paper presents a brief historical perspective on the use of meta-analysis in medicine with emphasis on the medical library. The authors conclude that in the future, medical librarians will play a significant role in the application of this useful technique. 相似文献

Chaos theory, informational needs, and natural disasters 总被引:2,自引:0,他引:2
Timothy L. Sellnow Matthew W. Seeger Robert R. Ulmer 《Journal of Applied Communication Research》2002,30(4):269-292
This study applies chaos theory to a system-wide analysis of crisis communication in a natural disaster. Specifically, we analyze crisis communication during the 1997 Red River Valley flood in Minnesota and North Dakota. This flood, among the worst in modern American history, consumed entire metropolitan areas, displacing thousands of people. The conditions and decisions leading to the disaster, and the subsequent reactions are retraced. Communication related to river crest predictions (fractals), the shock at the magnitude of the crisis (cosmology episode), novel forms of reorganizing (self-organization), and agencies that aided in establishing a renewed order (strange attractors) are evaluated. Ultimately, we argue that preexisting sensemaking structures favoring rationalized, traditional views of a complex system led officials to make inappropriately unequivocal predictions and ultimately diminished the effectiveness of the region's crisis communication and planning. 相似文献

Executives recognize the value of maintaining access to information. More managers filter their own e-mail rather than have assistants do this task. Organizing and storing data for future use are left to the personal preference of the individual manager. Is this in the best interest of the organization? Are data being stored in a manner causing them to be irretrievable in the future? Are irrelevant data being stored? This study investigates the strategies used to store and retrieve e-mail. The results revealed that the primary search strategy was a reliance on memory. The labels assigned to the e-mail folders triggered the user's memory. Although, in the short term, memory is sufficient for organizing and retrieving information, the lack of transferability and preservation of this information poses a danger. The association between the electronic file label and the stored information is unique to the manager and may lead to inaccessibility of relevant corporate knowledge in the future. 相似文献
