Parker, Edwin B.; And Others – 1967
An examination of 500 citations in 17 behavioral science journals was made for four time periods: 1950, 1955, 1960 and 1965. Fewer journals were examined in the earlier periods because some of the journals began after 1950, 1955, or 1960. The citations were examined to find out what sources were cited by which journals in which proportions.…

Eleven indexes of rurality and their effect on the classification of Michigan's 83 counties were investigated. The indexes were based on different concepts of rurality: (1) percent of employment in agriculture, fishing, and forestry; (2) population density and distance to urban centers; and (3) economic conditions. Index rankings were compared to…

The purpose of this paper is to suggest a technique of cluster analysis which is similar in aim to the Interactive Intercolumnar Correlation Analysis (IICA), though different in detail. Two methods are proposed for extracting a single bipolar factor (a "contrast compenent") directly from the initial similarities matrix. The advantages of this…

The report is introduced by a discussion on the rationale for selecting the research methodology used and an explanation of the…
