The use of computational diagrams and nomographs for the calculations that frequently occur in college administration is examined. Steps in constructing a nomograph and a four-dimensional computational diagram are detailed, and uses of three- and four-dimensional diagrams are covered. Diagrams and nomographs are useful in the following cases: (1)…

A model is proposed to explain the retrieval characteristics of an information retrieval system. (Author)

New models trace shifts among job losers, leavers, and entrants during economic change. (Author/AG)

A service is proposed to help authors of scientific papers to select journals to which to submit their manuscripts. The service could optimize the common interests of authors, readers/users, and science, by providing authors with a tool for reaching those readers who can most benefit from the information. (Author/LS)

The results of data analysis based on the multiplicative binomial model (MLTBIN) are compared with dichotomous data analyzed by using the simple logistic model (SLM). Specifically, the paper focuses on the issues of fit to these Rasch Models and estimates of item difficulty. The data indicate that the SLM and MLTBIN are not comparable in the…

Depending on their programming knowledge, students can become involved with the use of the computer in the construction and analysis of mathematical models, either through observing and/or interacting with a model developed by a programmer, or by becoming involved in the process of constructions and testing of models. The Bush-Mosteller Simple…

Describes a model developed to forecast energy demands and determine trends in demand for primary fuels. The energy model essentially considers primary energy sources as competing commodities in a market. (MLH)

Explores the properties of independent variables in information retrieval systems and defines a class of basic variables named M-factors. (Author/PF)

Considers conceptual and methodological components of information science evaluation studies. (Author)

A brief introduction is presented on how multiple regression and linear model techniques can handle data analysis situations that most educators and psychologists think of as appropriate for analysis of variance. (Author/BJG)

The major portion of this article considered the multiple regression model, used for industrial prediction situations, and fourteen separate episodes the author discussed in trying to make that model work. (Author/RK)

Outlines the facts being presented in the literature about mathematical models, their related components, and their practical and theoretical uses. (Author)

In this paper the mathematical structures of Bourbaki, the Piagetian developmental structures, and Polya's heuristic structures are compared. (SD)

A universal separation of speech and language is described by the use of one mathematical frame of reference. Also described are the accruing new comparisons and measurements made possible by a theoretically adequate separation of speech and language. (Author/RM)
