This article briefly describes the topics "beta coefficient"--a measurement of the price volatility of a company's stock in relationship to the overall stock market--and "market share"--an average measurement for the overall stock market based on a specified group of stocks. It then selectively recommends a database (file) on…

This paper reports the results of two studies of the readability of FORTRAN programs, i.e., the ease with which a programmer can read and analyze programs already written, particularly in the processes of maintenance and debugging. In the first study, low-level characteristics of 202 FORTRAN programs stored on the general-use UNIX systems at Bell…

This paper presents the major characteristics of the Chinese Character Code for Information Interchange (CCCII) and indicates its intended application for the interchange of Chinese information among computer systems and communication facilities, especially in library networks. It is considered sufficient for present day library applications,…

This article presents the results of a survey to investigate the current issues of computer use in public parks and recreation agencies and to document the experiences of agencies pioneering the use of electronic data processing. (PD)

A model which relates the access control and indexing functions. The model is based on concept protection which allows a practically unbounded number of levels (subsets) of protection without requiring a fixed hierarchy among the levels. This protection is offered independently for each of the user operations allowed. (Author)

Points out a viable and tested alternative to the use of lengthy account numbers. This alternative uses simple numbers and appends the lengthy numbers with their various sort keys and distribution codes to the tables of account names. (Author/DN)

This discussion paper seeks to highlight the need for standardization in the development of computer and telecommunications systems in Australian libraries to ensure an inbuilt capacity to interconnect with other systems. It presents a proposal for the establishment of an on-going mechanism responsible for identifying and developing standards…

A number of basic concepts relating to debugging are identified and a gross theory of debugging is described. (Author)

False drops occur in a system of random superimposed coding for edge-notched, punched, and feature cards. Formulae for the false dropping fraction are derived, and figures and tables are given for the calculated values in the most popular scheme. (Author/LS)

This handbook lists step-by-step the procedures for making Statistical Package for the Social Sciences (SPSS) runs on the interactive computer. The programs follow the Loma Linda University Revision 2.1 as adapted for the Data General Eclipse Systems. The four-step process includes instructions for developing the codebook, building the data and…

This manual contains a step-by-step explanation of a computer system designed specifically to enable the registration, examination, certification and recertification of pesticide applicators. The subsystems included are application processing, exam result processing, training and renewal processing. In addition, the system includes two management…
