The behavior of two real-time computer simulation models of melody recognition was compared with the performance of human subjects in this study. One of the models, INT1, recognized melodies by comparing specific intervals with stored intervals. The other model, CONT1, performed by comparing the contour of the stimulus melody with an array of…

This study examines possibility of ranking journals in physics by means of bibliometric regression models that estimate usefulness as it is reported by 167 physicists in United States and Canada. Development of four models, patterns of deviation from models, and validity and application are discussed. Twenty-six references are cited. (EJS)

Speech samples of 79 dysarthric patients were judged for voice quality, articulation, nasality, and prosody as well as overall intelligibility. Application of a multiple regression model found that intelligibility can be expressed as a linear combination of weighted perceptual dimensions with articulation as the strongest contributor to…

This study examined the relationship of chief executive psychological need for achievement with organizational structure. Models relating formalization, centralization, and integration with hypothesized determinants were investigated using LISREL and multiple regression analyses. Executive need for achievement and size related strongest to most…

Tests hierarchical regression model--library employee's salary is a function of library size, public sector collective bargaining strength, library's ability to pay, cost of living in area, presence of any union and union representing librarians in library--on three salary levels (department head, beginning librarian, clerical worker). (29…

This report describes efforts to test a model of leadership effectiveness that centers on "macro variables" and "discretionary leadership." Macro variables were represented by the complexity of the environment, context, and structure of a unit. Discretionary leadership was defined as influence over and above that typically…

Sixty-nine Israeli school principals completed questionnaires designed to reveal the factors contributing to the leadership styles they used when initiating curricular changes. The principals fell into three leadership categories: "Initiators," who seek change in accordance with long range policies and goals; "Responders," who…

Outlines a path analytic interpretation of data collected in light of the theoretical formulation of a dynamic model of memory. An investigation of industrial trainees' capacity to differentiate various ferrous and nonferrous metals is described which emphasizes the role of relational, strategic, and empirical knowledge in cognitive skill…

This report investigated the determinants of college students' overall evaluations of their academic programs (major field of study). The manner in which students weight the various domains of satisfaction and dissatisfaction in determining their level of overall program satisfaction was examined. The gender differences and field differences in…

In an application of contingency theory, data from 45 Arizona schools were analyzed to determine the relationships between three sets of independent variables (organizational structure, leadership style, and environmental characteristics) and the dependent variable (organizational effectiveness as perceived by principals and teachers). Contingency…

Evaluates the hypothesis that boomtowns enter a period of generalized crisis and loss of traditional values/attitudes; considers impact of energy development on residents' involvement in/attachment to their community, and perceived quality of community services. Uses linear and systemic models on data from three intermountain communities…

Examines the determinants of public school segregation in 65 metropolitan areas in 1968 and segregation changes between 1968 and 1976. Although city and suburban school segregation declined during the 1970s, segregation between cities and suburbs increased. Boundaries between city and suburban school systems appear to foster inequalities within…

Describes a study of 38 students at Eastern Oregon State College which identified mathematics proficiency as the key student characteristic leading to successful completion of computer science courses, and developed a model that accounts for 82 percent of the variation in students' final grades in computer courses for use by advisers. (LRW)

The purpose of this study was to determine the extent to which mastery testing contributes to instructional effectiveness and to determine the size of its effects in different outcome areas, such as aptitude and instructional time. A meta-analytic methodology was used to integrate findings from experimental studies. Twenty studies examined…

Proposes social structural view of poverty rates as a function of local opportunity instead of individual-level focus on who is poor. Defines poverty rates as a function of industrial structure and relative power of labor in a locality. Confirms theoretical model with data from 46 South Carolina counties. (LFL)
