Two possible modifications of the Bousfield et al. (1958) RR-IAR memory model were proposed to explain why backward associations between critical stimulus and experimental words do not result in increased experimental word false positive rates, while forward associations do. (Author)

Analyzes some of the results of The Survey of Canadian English as they concern the classroom teaching of language.

This National Institute of Education report discusses problems of data aggregation and disaggregation which arise whenever the unit on which variables are measured is different from the unit of analytical, conceptual or policy-related interest. For example, researchers may want to know the effects of family background, of peer groups, or of school…

The present study was undertaken to test the hypothesis that aggressive offenders have a greater amount of theta activity in their electrocortical rhythms than nonaggressive offenders, and also to examine the more general question of whether such individuals are cortically underaroused, underreactive, or more easily dearoused.

Treats the problem of testing an ordered hypothesis based on the ranks of the data. Statistical procedures for the randomized block design with more than one observation per cell are derived. Multiple comparisions and estimation procedures are included. (Author/RC)

Multidimensional scaling (MDS) a highly reliable measurement technique, often requires an overwhelming task of the subject in the data collection procedure. This investigation was designed to determine the loss of precision in solution associated with five degrees of systematic reduction in the data collection task. Data were simulated via Monte…

OUTLINED IN THIS ARTICLE IS AN APPROACH FOR DETERMINING LEVELS OF INCOME WHICH TYPIFY EQUIVALENT LEVELS OF POVERTY FOR FAMILIES IN DIFFERENT CIRCUMSTANCES. THE INDEX IS CONSTRUCTED WITH DESCRIPTIONS OF SUCH FAMILY CIRCUMSTANCES AS NUMBER AND AGE OF PERSONS AND GEOGRAPHICAL LOCATION. THE INDEX CAN BE USED TO DEFLATE FAMILY INCOME SO THAT IT IS…

This preliminary study attempted to determine the most effective search strategies for the topic "health effects" in relation to specific chemicals and/or pollutants--in this case, asbestos--for each of five selected Lockheed DIALOG data bases: BIOSIS Previews, Chemical Abstracts Condensates (Chemcon), NTIS, Enviroline, and Pollution…

The purpose of this study was to analyze Work Experience and Diversified Cooperative Training in-service teacher-coordinator perceptions to determine: (1) acceptance/rejection of 13 postulates, (2) acceptance/rejection of concepts/elements complementing the postulates, (3) the rank ordering of accepted concepts/elements, (4) acceptance/rejection…

Pennsylvania, one of the cooperating states in the Cooperative Accountability Project (CAP), was commissioned to complete an Impact Study which would provide a measure of interest, reaction, and benefits as described by readers of CAP publications and participants in CAP conferences or other activities. In part I of the study, evaluation forms…

An empirical assesssment of the space distortion properties of two prototypic hierarchical clustering procedures is given in terms of an occupancy model developed from combinatorics. Using one simple example, the single-link and complete-link clustering strategies now in common use in the behavioral sciences are empirically shown to be space…

A general guide to organizing and conducting reliable and useful community surveys is reported. Organization for the survey involves identifying and contacting relevant community groups, and meeting with organizational representatives. Constructing a questionnaire involves careful wording and ordering of questions, and determining if questions…

This paper briefly describes one model for interinstitutional cooperation in a continuing program of institutional research activities involving planned patterns of data collection and analysis (surveys, tests, follow-up data on student progress, etc.). Some of the advantages of continuing collaboration by several colleges with a central resource…

This study examined overlapping membership of voluntary associations as the basis of a statistical technique for analyzing community structure. An underlying assumption was that organizations select certain membership linkages in preference to others within a community. Thus one would expect to find points of integration and cleavage among…
