Popular measurement invariance testing procedures for latent constructs evaluated by multiple indicators in distinct populations are revisited and discussed. A frequently used test of factor loading invariance is shown to possess serious limitations that in general preclude it from accomplishing its goal of ascertaining this invariance. A process…

The text of an invited address on artificial intelligence (AI) research over the 1963-1968 period is presented. A survey of recent studies on the computer simulation of intellective processes emphasizes developments in heuristic programing, problem-solving and closely related learning models. Progress and problems in these areas are indicated by…

To synthesize knowledge concerning factors which affect occupational achievement through a set of explicit models based upon the concept of the socioeconomic life cycle, six major bodies of data from various sources were collected and subjected to secondary analysis. A number of items of lesser scope were gleaned from additional sources for use in…
