On-line serials collection analysis.

A design for an on-line serials decision-making and collection analysis system is proposed. It is composed of four basic components: citation data, conventional serial records data, utility/cost ratio compilation and journal ranking techniques, and user interface software. The system would have the ability to respond specifically to user interest profiles and to integrate locally generated data. It is postulated that such a system is capable of satisfactorily resolving the major criticisms of the use of citation data for selection purposes: that libraries are diverse in their interests and that no aggregate list can be more than generally relevant; that the inclusion of cost data is essential and that citation ranking without regard to cost can be misleading; and that other relevant data should be considered as well.

Intracoronal pressure during crown cementation.

A model system was developed which recorded the intracoronal pressure during crown cementation at three locations simultaneously. Peak pressures and residual pressures were greatest with zinc phosphate cement. The zinc oxide-eugenol cement generated the smallest amount of peak and residual pressures. The polycarboxylate cement exhibited an intermediate pressure intensity. The uneven intracoronal pressure in the cement suggests a complex flow pattern capable of developing the separation of phases that earlier work reported. However, the small residual pressure indicates that these internal back pressures appear to play a limited role in preventing a complete seating of a crown.

Systematic serials selection analysis in a small academic health sciences library.

This paper describes the implementation of a straightforward quantitative technique to analyze the serials collection of the Medical Library at the University of Missouri-Kansas City (UMKC). Our simplified operations research approach resulted in a savings of nearly $1400 per year in subscriptions costs without reducing the net number of seven hundred titles or causing an imbalance in the subject distribution of our collection. By detailing both the rationale behind the process and the actual steps followed at UMKC, we hope to demonstrate that operations research techniques can be used practically and successfully even in small health sciences libraries. In the Appendix a more general and more rigorous operations research approach to the analysis of serials collections is also presented in a fashion that is, as far as possible, not mathematically forbidding.
