THE PURPOSE OF THIS STUDY IS TO ESTIMATE THE MANPOWER REQUIREMENTS FOR THE NATION FOR 144 REGIONS THE TYPES OF SKILLS AND WORK ABILITIES REQUIRED BY AGRICULTURE IN THE NEXT 15 YEARS, AND THE TYPES AND AMOUNTS OF EDUCATION NEEDED. THE QUANTITATIVE ANALYSIS IS BEING MADE BY METHODS APPROPRIATE TO THE PHASES OF THE STUDY--(1) INTERRELATIONS AMONG…

BASED ON EMPIRICAL DATA ACCUMULATED FROM TWELVE JUNIOR COLLEGES UNDER THE 2-SEMESTER CALENDAR, THE MODEL DEVELOPED IN THIS STUDY CAN BE USEFUL IN PREDICTING CHANGES IN PLANT USE UNDER THE 4-QUARTER CALENDAR. THIS CALENDAR REVISION HAS FOUR CONSTRAINTS--(1) THE SENIOR INSTITUTIONS IN THE STATE HAVE ADOPTED IT, (2) THE STUDENT'S CHOICE OF QUARTER IN…

The multiple regression or general linear model (GLM) is a parameter estimation and hypothesis testing model which encompasses and approaches the more familiar fixed effects analysis of variance (ANOVA). The transition from ANOVA to GLM is accomplished, roughly, by coding treatment level or group membership to produce a set of predictor or…

If overattribution--the tendency for observers to think actors' attitudes match their behaviors even when behaviors are not freely performed--results from the fundamental attribution error, then observers must believe the coerced behavior is attributionally informative. This assumption was tested by (1) investigating the extent to which attitude…

A two-year study that attempted to measure patterns of pupil attributions for success and failure in mathematics is reviewed. An attribution pattern variable (ATTPAT) was created to categorize individuals studied into three groups. The first group had an attribution pattern thought to lead to generalized low expectancies for success. Students…

This paper is a theoretical discussion of several functions of knowledge systems based on the idea of partial matching, that is, comparison of two or more descriptions by identification of their similarities. Several knowledge system functions are described in terms of partial or best matchings including analogical reasoning, inductive inference,…

Some aspects of simultaneous tests for means are reviewed. Specifically, the comparison of univariate or multivariate normal populations based on the values of the means or mean vectors when the variances or covariance matrices are equal is discussed. Tukey's and Dunnett's tests for multiple comparisons of means, Scheffe's method of examining…

When examining a repeated measures design with independent groups for a significant group by trial interaction, classical analysis of variance or multivariate procedures can be used if the assumptions underlying the tests are met. Neither procedure may be justified for designs with small sample sizes and dichotomous dependent variables. An omnibus…

This paper discusses the theory and presents examples of free-association norms. Examples from several categories of free-association data are given. Their use in experiments on cultural characteristics of the associative structures of words are also explained. A graph of the relationship between primary and secondary associations and tables of…

The evaluation model for mastery testing as proposed by Emrick (1971) represents an empirical approach to determining the most appropriate mastery criterion score that should be established in those testing situations which entail decision making relative to the continued progression or possible recycling of students in a given learning sequence.…

Latent trait test score theory is discussed primarily in terms of Birnbaum's three-parameter logistic model, and with some reference to the Rasch model. Equations and graphic illustrations are given for item characteristic curves and item information curves. An example is given for a hypothetical 20-item adaptive test, showing cumulative results…

The number of students expected to enroll in Montgomery College yearly through 1985 is projected on the basis of a model incorporating past trends, population projections, economic indicators, and other factors on which viable assumptions about the future can be based, into a system of linear equations expressed in matrix notation. The model…

Through Monte Carlo procedures, three different techniques for estimating the parameter theta (proportion of the "shocks" remaining in the system) in the Integrated Moving Average (0,1,1) time-series model are compared in terms of (1) the accuracy of the estimates, (2) the independence of the estimates from the true value of theta, and…

Formal proofs are given of the effectiveness under well-defined conditions of the thesaurus method in information retrieval. It is shown, in particular, that when certain semantically related terms are added to the information queries originally submitted by the user population, a superior retrieval system is obtained in the sense that for every…

This paper provides a broad reexamination of the correlates of faculty age, incorporating several measures of research activity and other related professional achievement variables. The data are derived from a large-scale, nationally representative survey of college and university faculty members; analyses are based on a subsample of all doctorate…
