On the basis of analytical and observational work during Phase 1 of this project, an experiment was developed to test the effects of systematic variations in the level of the independent variable "instructional cue" (I.C.). The first phase of the research consisted of the development of a precise operational definition of the variable. This was…

An introduction to the problems of variable-length message transmission in distributed loop computer networks, with a summary of previous accomplishments in the area, begins this technically-oriented document. An improved technique, overcoming some of the inadequacies in presently used techniques, is proposed together with a conceptual model of…

This report by the Computer Utilization Group which was set up in 1960 by the Organization for Economic Cooperation and Development (OECD) consists of two parts: 1) a brief statement of conclusions, recommendations and suggestions for research by the data bank panel and a list of the panel members and 2) the background report prepared by Klaus…

The subject of access control mechanisms in computer systems is concerned with effective means to protect the anonymity of private information on the one hand, and to regulate the access to shareable information on the other hand. Effective means for access control may be considered on three levels: memory, process and logical. This report is a…

This report presents the results of a survey to ascertain the extent of computer use in Canadian education. Of 307 administrative units responding to the questionnaire, 83 indicated they used electronic data processing services. Business management services accounted for most of the computer use, while administrative and instructional services…

The aim was to design a seminar which would allow time for each individual to grow into the subject, to reflect, to participate in discussions, to come back to points as appropriate -- the antithesis of a 'crash course'. The intention was to give all participants a representative introduction to the whole range of what is now available, and to…

Libraries, as well as larger information networks, are necessarily based upon the storage of information files consisting in many cases of written materials and texts such as books, serials, abstracts, manuscripts and archives. At the present stage of the "information explosion" no librarian can afford to ignore the contribution of…

This second volume of a research report on manpower information availability compares alternative sources of manpower data in a poverty area of Philadelphia. The first volume recognizes the need for data, yet it ignores the statistical problems of comparability, comprehensiveness, and accessibility inherent in the agency records which were…

This report is based on hearings that the subcommittee held on July 1, 1970, entitled "Economy in Government Property Management--Procurement of Data Processing Equipment" as well as General Accounting Office and General Services Administration reports. It focuses upon the phenomenal growth in the use of automatic data processing equipment by the…

Engineering and technician enrollments for Fall 1969 are reported for associate and bachelor's degree programs in engineering technology and industrial technology, and for engineering degrees at the bachelor's, master's, and doctor's levels. Statistical tables were produced by a computer analysis of data from 269 engineering schools and 558 other…

The characteristics of the Intrex subject/title inverted file are analyzed. Basic statistics of the inverted file are presented including various distributions of the index words and terms from which the file was derived, and statistics on stems, the file growth process, and redundancy measurements. A study of stems both with extremely high and…

The third phase of a four-phase program developed by the Federal Library Committee Task Force on Library Automation in conjunction with its overall objective of reviewing and reporting upon the status of automation in Federal libraries is reported. The first phase of the overall program appraised the current activities in library automation and…

A major design objective of the Natural Resource Information System entailed the use of remote sensing data as an input to the system. Potential applications of remote sensing data were therefore reviewed and available imagery interpreted to provide input to a demonstration data base. A literature review was conducted to determine the types and…

Training programs for data processing personnel are plagued by the rapid turnover of the technology involved. An attempt was made to provide a self-paced training plan for a large, data processing staff. Factor analyses of questionnaires about the skills and tasks involved divided the population into specialization groups. Within the…

An automated SDI service based on tapes supplied by DDC, Science Abstracts, and Engineering Index is evaluated as a component element of the entire HDL information system. Current studies for improving the efficiency are briefly described,--in particular, the establishment of a parameter reference service that should shorten the lead-time for the…
