A review of literature dealing with moon phases and psychiatric emergencies was undertaken. (Editor)

Within lay explanation of actions, several significant inferences are assumed to follow from the partition between endogenous and exogenous attributions. An endogenous action is judged to constitute an end in itself; an exogenous action is judged to serve as a means to some further end. (Editor/RK)

In numerous applications of the analysis of variance, it is necessary to compute the power of F tests having numerically high alpha (significance) levels. This article tabulates the power of F tests for a variety of degrees of freedom. (Author/JKS)

Demonstrates the value of dynamic analysis of event-history data for the sociological study of change in categorical variables. An event history records dates of events that occur for some unit of analysis (i.e., an individual's marital or employment status, or outbreaks of riots or wars). (Author/AV)

A rigorous definition for a factor analysis model and a complete solution of the factor score indeterminacy problem are presented in this technical paper. The meaning and application of these results are discussed. (Author/JKS)

A simple roof is presented: that the squared multiple correlation of a variable with the remaining variables in the set of variables is a lower bound to the communality of that variable. (Author/JKS)

The use of interaction and non-linear terms in multiple regression poses problems for determining parsimonious models. Several computer programs for using these terms are discussed. (JKS)

A study conducted to examine the characteristics of the literature available to students in Nigeria focused on the references to periodical articles that were cited in selected social science theses and dissertations submitted to the University of Ibadan during 1965-70. Information recorded for each reference included place of publication, age,…

This article is a critique of a study which concluded that there is a relationship between the use of obstetrical drugs and the behavior of infants during the first month of life. (BRT)

This article is a reply to a critique of the authors' study which concluded that there is a relationship between the use of obstetrical drugs and the behavior of infants during the first month of life. (BRT)

This article demonstrates how to construct two types of graphs, the line plot, and the stem and leaf plot. States that these graphing techniques improve students' ability to understand tabular data. An instructional model is presented for directing lessons which use the two types of graphs. (JDH)

A study of the use of the OCLC interlibrary loan subsystem revealed that nearly two weeks elapse between the entry of a request into the subsystem and receipt of the item. Comparison with other studies shows little change since 1979. (Author/EM)

Study determines that solutions derived by multiple group analysis and item-total correlation analysis were generally most interpretable from a psychological perspective. It was concluded that their application to test construction is preferred over Procrustean or confirmatory maximum likelihood approaches. (RB)

Describes two new measures of consistency which refer to the extent to which more closely related scale types are found together in Holland's Self-Directed Search sort. One measure is based on the hexagonal model for use with three-point codes. The other is based on conditional probabilities for use with two-point codes. (Author/ABL)

Suggests that improving the data collected for a study will lead to the development of better models to analyze that data. Also urges researchers to have a more critical attitude toward the literal interpretation of test results. (RB)
