THE STUDY DEMONSTRATED THAT THE RATIO OF UNSKILLED TO SKILLED EMPLOYMENT AND UNEMPLOYMENT VARIES FROM THE PEAK TO THE TROUGH OF THE BUSINESS CYCLE. DATA PRIMARILY FROM "EMPLOYMENT AND EARNINGS AND MONTHLY REPORT ON THE LABOR FORCE," MARCH 1967 WERE USED IN RELATING THE ANNUAL UNEMPLOYMENT RATES FOR CRAFTSMEN AND LABORERS TO BUSINESS CYCLE PEAKS…

AN ATTEMPT IS MADE TO ESTABLISH A THEORETICAL FOUNDATION FOR GROUP PROPERTY AND LIABILITY INSURANCE AND TO ADVANCE THE GENERAL HYPOTHESIS THAT THE PRINCIPLES USED IN INSTALLING AND ADMINISTERING GROUP LIFE AND HEALTH INSURANCE ARE APPLICABLE TO THE INSTALLATION AND ADMINISTRATION OF GROUP PROPERTY AND LIABILITY INSURANCE. A SURVEY WAS CONDUCTED TO…

THREE STRUCTURED Q SORTS CONTAINING LIBERAL, CONSERVATIVE, PROGRESSIVE, AND TRADITIONALIST STATEMENTS ENABLED THE INVESTIGATOR TO TEST THE HYPOTHESIS THAT INDIVIDUALS WHO ARE LIBERAL IN THEIR SOCIAL ATTITUDES WILL TEND TO BE PROGRESSIVE IN THEIR EDUCATIONAL ATTITUDES, WHEREAS INDIVIDUALS WHO ARE CONSERVATIVE IN THEIR SOCIAL ATTITUDES WILL TEND TO…

Provided are hypotheses and evaluation forms to evaluate vocational-occupational-technical education (V.O.T.E.) programs whose purposes include the mainstreaming of handicapped students. Materials are geared toward testing the following five hypotheses: most occupational administrators can cite specific examples of formal or informal evaluations…

The testing of a priori contrasts, post hoc contrasts, and experimental error rates are discussed. Methods for controlling the experimental error rate for a set of a priori contrasts tested simultaneously have been developed by Dunnett, Dunn, Sidak, and Krishnaiah. Each of these methods is discussed and contrasted as to applicability, power, and…

A procedure was developed within hypothesis-testing logic that allows researchers to support a hypothesis that has traditionally been the statistical or null hypothesis. Four activities involved in attainment of this goal were discussed: (1) development of statistical logic needed to define the sampling distribution associated with the hypothesis…

The Chi-Square Test for Hierarchical Dependency (THD) is presented. The THD tests the hypothesis that all members of a population who possess a certain skill are a subset of the members who possess another skill. This hypothesis is basic to the writings of several prominent theorists, such as Gagne and Piaget. The THD is designed as an improvement…

Utilizing a datafile compiled by Gene Summers from various censuses of governments publications, the following hypotheses were tested: (1) a relationship exists between county government revenue and the level of manufacturing, the size of the population in the county, and the median family income; and (2) a change in the former is due to changes…

A theory of Socratic tutoring was developed in the form of pattern-action rules for a computer program. The rules were derived from analyses of a variety of tutorial dialogs. The 23 rules were designed to formalize causal knowledge and reasoning, and they included such abilities as forming hypotheses, distinguishing between necessary and…

Stability of Type I error rates and power are investigated for three forms of the Box test and two forms of the jackknife test with equal and unequal sample sizes under conditions of normality and nonnormality. The Box test is shown to be robust to violations of the assumption of normality when sampling is from leptokurtic populations. The…

Faced with a nonstandard, complicated practical problem in statistical inference, the applied statistician sometimes must use asymptotic approximations in order to compute standard errors and confidence intervals and to test hypotheses. This usually requires that he derive formulas for one or more asymptotic sampling variances (and covariances)…

Methods of internal labor market analysis for three organizational areas are presented, along with some evidence about the validity and utility of conceptual descriptions of such markets. The general concept of an internal labor market refers to the process of pricing and allocation of manpower resources with an employing organization and rests…

The primary purpose of this study was to determine empirically whether an individual's cognitive style differentially influences his hypothesizing behavior within a relatively simple information processing task. A characteristic of cognitive style explored is the manner in which an individual perceives and analyzes a stimulus configuration;…

This monograph contains the second section, operations at the variable level, of a report of studies done in Helsinki, Finland, describing school achievement in terms of ability, trait, situational, and background variables. The report (1) investigates the structure of school achievement, (2) describes school achievement in terms of selected…

This paper presents an integrative theoretical framework for the conceptualization of the marriage relationship in terms of Kelly's psychology of personal constructs. Personal construct theory offers a productive model which can account for research findings related to most of the variables found to be relevant to marital success. Personal…
