A model of departmental support expenditures is constructed. The requirements for administrative and technical staff and for operating funds of a university's academic units were analyzed, and these were related to a number of quantitative characteristics of the units. (Author/MLW)

Presents the results of a study conducted to determine the allocation of general revenue sharing funds to libraries from 1973 through 1977 and to estimate the impact of these funds on library budgets around the country. Data are summarized in 6 tables and a reference list is included. (Author/JL)

Contrasts aptitude by treatment interaction (ATI) and hierarchical linear modeling (HLM) methods for making cross-level inferences between individual-level and group-level factors in school effectiveness research. Recommends HLM when intraclass correlations are high. ATI is suitable when intraclass correlations are low, but partitioning the…

Assessed association between length of maternity leave and quality of mother-infant interaction. Found a direct association between shorter leave and more negative affect and behavior; mothers with more depressive symptoms or who perceived their infant as having a difficult temperament, and with shorter leaves expressed less positive affect,…

Describes a study that investigated the relationship between an institution's academic library performance measures and undergraduates' library use and educational outcomes. Discusses results of regression analyses and suggests that the most important implication of this study is the creation of a new model of academic library quality. (Author/LRW)

Data on National Direct Student Loan Program borrowers at the University of North Carolina illustrate the use of a discriminant function analysis model and an alternative model identifying characteristics of borrowers who repay and borrowers who default.

The London Education Authority (LEA) stresses the importance of developing the interface between quantitative models of assessment and qualitative assessments, describing an interdisciplinary approach to the development of models of educational accountability, recommends an alternative method, data envelopment analysis, and compares it to the…

The effects on mathematics achievement of having fifth graders engage in elaborative and integrative processing were studied using 121 students. Subjects were randomly assigned to cognitive-processing, fact-sheet, or control groups. Results show that cognitive processing is related to memory and understanding and is more effective for higher…

Outlines an approach to teaching management control activities via the use of case study material, microcomputer technology, and commercially available software. A case study for use by an undergraduate class is described; it includes a single regression analysis, a spreadsheet model, and a description of the man/machine decision process.…
