Peer reviewedWerts, Charles E.; And Others – Educational and Psychological Measurement, 1973
Purpose of this paper is to provide an alternative formulation which allows for the model parameters to be determined given the structural specification of zero mean error and independence among errors for different items and between errors and true scores. (Authors)

In this paper the amount of frustration in a section of books is derived from a model that includes the effects of variable book circulation and the nondeterministic nature of book use. (Author/DH)

Stanfel, Larry E. – Information Storage and Retrieval, 1973
A review is given of doubly-chained trees for information retrieval. It is shown that the chaining steps may be of different cost depending upon whether the step is vertical or horizontal. The problem of constructing an optimal retrieval tree is formulated mathematically and a solution procedure given. (5 references) (Author/KE)

Peer reviewedCooper, Michael D. – Journal of the American Society for Information Science, 1972
A Mathematical model for use in studying how to minimize the cost of operating a mechanized retrieval system is developed. Through the use of cost analysis, the model provides a method for comparative evaluation between information retrieval systems. (15 references) (Author/SJ)

Peer reviewedCody, R. D. – Journal of Geological Education, 1972
Presents the derivation of rotation and reflection matrix representation of symmetry operators as used in the initial discussion of crystal symmetry in elementary mineralogy at Iowa State University. Includes references and an appended list of matrix representations of the important crystallographic symmetry operators, excluding the trigonal and…

Peer reviewedKrauze, Tadeusz K.; Hillinger, Claude – Journal of the American Society for Information Science, 1971
A mathematical model is presented which explains the observed exponential growth rates of citations and references in a scientific discipline. The independent variables are the growth rate of the number of articles published and the decay rate of citation of old literature. (13 references) (Author)
Descriptors: Citations (References), Growth Patterns, Mathematical Models, Scholarly Journals
