Numerical tables of mathematical functions are in continual demand by scientists and engineers for preliminary surveys of problems before programming for computing machines. This handbook was designed to provide scientific investigators with a comprehensive and self-contained summary of the mathematical functions that arise in physical and…

Catastrophes that can have disastrous impacts on information systems are discussed. An information system designer must assume that eventually a disaster will occur, and therefore must plan accordingly. Several approaches to disaster recovery are described, and five key lessons regarding disaster are given. (Author)

It is shown that Trueswell's empirical 80/20 rule arises from type of stochastic model for library loans presented by Burrell and Cane. Particular attention is paid to previously suggested uses of rule in identifying "core collection" for library noting that length of time period is of crucial importance. (20 references) (EJS)

Discusses the use of tables versus graphs and describes a study that investigated how easily the information presented in each format is understood. Emphasizes the needs of the reader for simplification and clarity and considers implications for editors and referees when making suggestions to authors of journal articles. (LRW)

This article demonstrates how to construct two types of graphs, the line plot, and the stem and leaf plot. States that these graphing techniques improve students' ability to understand tabular data. An instructional model is presented for directing lessons which use the two types of graphs. (JDH)

It is shown that there is no ambiguity in Bradford's theory of distribution. Starting with two basic postulates laid down by Bradford, a mathematical expression is derived such that its curve agrees with the experimentally plotted data for periodicals in fields of applied geophysics and lubrication. Five references are listed. (Author/EJS)

Presents a summary of research on the effect of tabular and graphic presentation on reader reaction, reader retention, and reading time that found that comprehension, reaction, and reading time are enhanced by graphic aids. (JOW)

Discusses the notion that knowledge grows exponentially and describes its growth mathematically by an exponential function. Growth patterns in subfields of knowledge or research areas are described citing related research. Interpretation of growth rate statistics and forecasts are included. Thirty-three references and statistics used for graphs…

Structural models that yield circumplex inequality patterns are reviewed, focusing on a model developed by T. W. Anderson (1960). A modification is proposed to this model to allow for negative correlations. This model may be reparameterized as a factor analysis model with nonlinear constraints on the factor loadings. (SLD)

Graphs don't always show what the graphers say they do. The most notorious recent example of a misleading graph is the one produced by the U.S. Department of Education that plots National Assessment of Educational Progress (NAEP) reading scores against total federal spending on education. This graph was taken apart by Howard Wainer and Daniel…

The Position Analysis Questionnaire (PAQ) is a structured job analysis procedure that provides for the analysis of jobs in terms of each of 187 job elements, these job elements being grouped into six divisions: information input, mental processes, work output, relationships with other persons, job context, and other job characteristics. Two…

Statistics on brodcast and production hours of public television stations and licensees in the United States, Puerto Rico, and American Samoa for fiscal year 1971 are compiled. The major objective is to provide the public boadcasting community--including legislators, administrators, and researchers, as well as the communications industry as a…

Florida's urbanized rural population consists of 3 segments: persons in places under 2,500 population; persons in suburbs or open country but not on farms; and persons in other urban territory. This urbanized rural population continues to grow, despite annexation and consolidation by urban communities, and the wide disparity that once existed…

A quantitative comparison of peer versus bibliometric procedures for rating the quality of U.S. universities is presented. The quality of graduate faculty is measured by the Roose-Andersen peer rating, while bibliometric ratings are based on the number, average "quality," and total influence of university papers in each field.…
