Describes how experts create and use "bundles"--organized, highly selective collections of information--to help solve problems and maintain situation awareness. Based on fieldwork in an intensive care unit, five examples of bundles are described that illustrate the variety of bundles in use. A summary of bundle properties is given. (AEF)

Information retrieval (IR) is driven by a process that decides whether a document is about a query. The purpose of this article is to consider "aboutness" from a fundamental, neutral perspective, to shed light on the nature of aboutness by formalizing properties describing it, and to define a set of reasonable properties of aboutness,…

An upstate New York district became a pilot site for a technology industry initiative to build software systems that eliminate traditional interdepartmental barriers.

Introduces a hybrid method for abstracting Chinese text that integrates the statistical approach with language understandings, incorporating some linguistics heuristics and segmentation into the abstracting process. Initial responses from application to Chinese newspaper articles show that the method contributes much to the flexibility and…

Experimental results show that a word-based arithmetic-coding scheme, a fractional-bit compression algorithm which is known to be time consuming, can achieve a higher compression performance for Chinese text. This article examines how to cascade the word-segmentation model with a faster alternative, the integral-bit compression algorithm.…

Prompted by the "millennium bug," many school districts are in the process of replacing non-Y2K-compliant information systems. Planners should establish a committee to develop performance criteria and select the winning proposal, estimate time requirements, and schedule retraining during low-activity periods. (MLH)

Provides an introduction to articles in this special "Perspectives" issue of "Journal of the American Society for Information Science and Technology."

The effects of long-term hospitalizations can be severe, especially among older adults. In Manitoba, between fiscal years 1991/1992 and 1999/2000, 40 per cent of acute care hospital days were used by the 5 per cent of patients who had long stays, defined as stays of more than 30 days. These proportions were remarkably stable, despite major changes…

How, where and why GIS is taught has been debated heavily in the geography literature. This article is a contribution to that debate, because it offers a new perspective from which to teach GIS: problem-based learning. In a problem-based learning classroom, theoretical foundations and the real world of problems are understood as constitutive of…

The 2004 recipient of NCA's Gerald M. Phillips Award for Distinguish Applied Scholarship, Brent Ruben's professional record spans more than three decades and has focused in four major areas: organizational development, communication/information systems, medical/health communication, and intercultural communication.

Once upon a time, there was the mainframe. Only a handful of applications were available on this great big computer. A few hearty users took advantage of these applications, often accessing them one at a time. Folks generally did not expect to use any application with another. Why would they? Now, of course, the world is very different. College…

The author of this article describes the central IT structure of her institution, the University of Wisconsin at Madison. Based on her experiences, she observes that building and maintaining a community of support that spans the central IT organization and the distributed IT support providers presents real challenges. As such, she believes that…

In the wake of Hurricane Katrina, organizations are reexamining their strategies for ensuring the continuity of their core operations. Business continuity has become a focus for higher education institutions nationwide as they watch Gulf Coast administrators who are experiencing the very real problems of recovering from a natural disaster. For…
