A Teletype Model 37 machine has been modified for the coding of chemical structures. The coding rate of this model is higher than that of other machines of this type. The rationale for choosing this particupar type of input equipment is presented. (6 references) (Author/SM)

ISDED, designed as an international classification system but adaptable to national systems, is an inter-departmental project of Unesco administered by the Office of Statistics. A three stage, five digit system by level, field and programme, ISCED consists of over 450 categories of education with their respective definitions. (JB)

Sooner or later a perfected edition of the present cataloging rules, purged of the noxious compromises, will have to be prepared. (Author)

The use of multiple regression as a data-analytic tool is examined for the cases of balanced and unbalanced designs. The utility of this method for testing specific contrasts, both orthogonal and nonorthogonal is discussed and some interpretive cautions are examined. (Author)

The major premise of the present study was that rules are not only a useful descriptive concept but may actually be acquired by subjects and govern the selection process. (Author)

Addressing the problem of protecting confidential information and data stored in computer databases from access by unauthorized parties, this paper details coding schemes which present such astronomical work factors to potential code breakers that security breaches are hopeless in any practical sense. Two procedures which can be used to encode for…

THE NINE APTITUDES MEASURED BY THE GENERAL APTITUDE TEST BATTERY ARE INTELLIGENCE, VERBAL APTITUDE, NUMERICAL APTITUDE, SPATIAL APTITUDE, FORM PERCEPTION, CLERICAL PERCEPTION, MOTOR COORDINATION, FINGER DEXTERITY, AND MANUAL DEXTERITY. THIS MANUAL PRESENTS (1) PERCENTILE EQUIVALENTS OF APTITUDE OR STANDARD SCORES FOR ADULTS, 10TH GRADERS, AND 9TH…

NORMS ARE SHOWN IN TERMS OF CUTTING SCORES FOR EACH OF THE APTITUDES FOUND TO BE SIGNIFICANT FOR THE OCCUPATION. THE STANDARD ERROR OF AN OBTAINED SCORE FOR EACH APTITUDE OF THE GENERAL APTITUDE TEST BATTERY IS APPROXIMATELY SEVEN POINTS. INCLUDED IN THE MANUAL ARE (1) AN ALPHABETICAL INDEX TO APTITUDE TEST BATTERIES, (2) AN INDUSTRIAL INDEX TO…

Psychologists and linguists often suggest that empathy or role-taking ability is important in the communication process because it enables a speaker to consider in advance the informational demands of his audience. Despite the vintage of the empathy-effective communication hypothesis, it has never been directly tested. In this study, empathy was…

Nearly all organizations are faced with problems of classifying and coding financial data, management and technical information, components, stores, etc. and need to apply some logical and meaningful system of identification. This report examines the objectives and applications of classification and coding systems and reviews eight systems…

The alphanumeric code is a system put forward with the hope that it will bring uniformity in methods of inventory-taking and describing all sorts of audio-visual material which can be used in either French or English. The alphanumeric code classifies audio-visual materials in such a way as to indicate the exact nature of the media, the format, the…

A model dealing with the function of elaboration in word encoding was evaluated using a 2-list recognition procedure that varied encoding time within the presentation list. The model predicted that elaboration, reflected in the incidence of false positives to associates of words presented in the recognition list, would increase as presentation…

This research found storage of information in a short-term memory task to have a detrimental effect upon perceptual processing in a detection task. Additionally, it was determined that the magnitude of the effect was related to the degree of visual similarity, but not acoustic similarity, between the stored information and the perceptual…

Organization theory emphasizes groupings of items on the basis of a variety of characteristics, and the role of the learner as an active processor or encoder of information. Research on organization theory as it is applied to memory and recall of prose is reviewed here. (BW)
