A brief commentary from the Museum Association of New York (MANY) on the unprecedented gap posed by baby-boomer retirement. Based, in part, on MANY's white paper, “Who's Next? Questioning the Future of Museum Leadership in New York State,” this essay deals with questions of succession, leadership and general differences in New York's museum community.  相似文献

In this essay, we respond to the narratives and essays in this issue by examining organizational power issues related to researchers and institutional research boards (IRBs). Rather than taking a singular perspective on power, we use multiple perspectives and suggest that the cumulative analyses provide the best understanding of IRBs and organizational power.  相似文献

Analysis of Statistical Question Classification for Fact-Based Questions   总被引:1,自引:0,他引:1  
Question classification systems play an important role in question answering systems and can be used in a wide range of other domains. The goal of question classification is to accurately assign labels to questions based on expected answer type. Most approaches in the past have relied on matching questions against hand-crafted rules. However, rules require laborious effort to create and often suffer from being too specific. Statistical question classification methods overcome these issues by employing machine learning techniques. We empirically show that a statistical approach is robust and achieves good performance on three diverse data sets with little or no hand tuning. Furthermore, we examine the role different syntactic and semantic features have on performance. We find that semantic features tend to increase performance more than purely syntactic features. Finally, we analyze common causes of misclassification error and provide insight into ways they may be overcome.  相似文献

Librarians offer a unique perspective on e-books: on one hand they collect these resources and train users as part of their jobs, while on the other hand, they may be users of e-books themselves. With recent increases in research expectations for Canadian academic librarians, this study aimed to discover: when librarians do research, do they use e-books and how often are they using them? This study examines the results of a survey of 392 academic librarians from across Canada. The survey generated data on librarians' use of, and attitudes towards, e-books. While a number of studies examine the use and opinions of e-books among other user groups, this study examines how librarians search for or use e-books differently than other user groups. Results will help librarians to improve their liaison work and make more informed collection development decisions at their own institutions.  相似文献
