User involvement is assumed to be beneficial to innovation processes. Intermediary user organisations contribute to articulating societal demands for innovations. However, the learning processes inside these organisations are still not understood well. Therefore, this paper empirically investigates intermediaries using an event history approach. It yields characteristic learning mechanisms, e.g. concerning the management of expectations or actively building a case. If intermediaries overcome challenges regarding positioning, representation and the level of proactivity, they can play a precarious role in demand articulation in the context of new technologies. 相似文献

This column reports the results of a survey conducted of medical librarian participants in medical informatics training at the University of Pittsburgh. This small study was undertaken in order to identify issues in training different kinds of library and information science practitioners in medical informatics. 相似文献

This paper investigates the number of expansion terms to use in automatic query expansion by examining the behavior of eight
retrieval systems participating in the NRRC Reliable Information Access Workshop. The results demonstrate that current systems
are able to obtain nearly all of the benefit of using a fixed number of expansion terms per topic, but significant additional
improvement is possible if systems were able to accurately select the best number of expansion terms on a per topic basis.
When optimizing average effectiveness as measured by mean average precision, using a fixed number of terms increases the score
a large amount for a small number of topics but has little effect for most topics. The analysis further suggests that when
a topic is helped by automatic feedback, the increase is from a set of terms that reinforce each other rather than from the
system finding a single excellent term. 相似文献

Those entering the world of publishing standards for the first time may find it a baffling alphabet soup—with NISO, ANSI,
BISG, IEEE, NIST, and ANSC floating on a broth bubbling with activity. Jacob and Rings sort out the acronyms, explaining what
each of these groups does and how they interact.

to the library and information science areas, and for assessing their impact and potential impact on OCLC and its strategic
planning processes. 相似文献

Abstract The aim of this study was to understand the role that agricultural consultants in New Zealand were undertaking in the Research, Development and Extension (RD&E) system—and in particular in relation to environmental extension. New Zealand does not have a public extension service and hence there is a strong reliance on consultants and regional councils for environmental management information and advice. As they are independent of the formal RD&E system there is no guarantee that RD&E outcomes are reaching farmers, nor that effective environmental extension is occurring. The study used a combination of case studies, phone interviews with informed persons and a national web survey to explore the role of the consultant. The study found that agricultural consultants are playing an important role in working with farmers to improve agricultural production. There are, however, indications that gaps have developed over time between agricultural consultants and the agricultural research sector which limit the effectiveness of the RD&E system. Agricultural consultants are playing a minimal role in proactive environmental extension because insufficient market forces are driving this role. The paper suggests that a national database of agricultural consultants could improve the flow of tailored information between research and agricultural consultants and also suggests mechanisms where consultants could be better integrated into the RD&E system and provide feedback to research programs. Market failure in the area of environmental extension could be addressed by publicly funded incentive programs. 相似文献

This article assesses the quality of 12 American doctoral programs by counting the number of publications of their Ph.D. graduates in a large number of criminology and criminal justice journals, and in 20 more “academic” journals. While half of the Ph.D. graduates had no publications, the 4 percent who were the most productive (the “stars”) accounted for one third of all journal articles. Publication rates up to graduation predicted publication rates after graduation. The University of Maryland, Michigan State University, the University of California at Irvine, Florida State University, and Sam Houston State University had the most productive Ph.D. graduates in academic journals. There was a significant correlation between the productivity of a program's Ph.D. graduates and the productivity of its faculty members. The academic publication rate was influenced most by prevalence (the percentage of Ph.D.s with at least one publication), rather than by the percentage of “stars” or the frequency of publications. 相似文献
