The main purpose of the paper is to estimate the efficiency of a big public university in Italy using individual student-level data, modeling exogenous variables in human capital formation through a heteroscedastic stochastic frontier approach. Specifically, a production function for tertiary education has been estimated with emphasis on…

Can people make perfect use of task-relevant information in working memory (WM)? Specifically, when questioned about an item in an array that does not happen to be in WM, can participants take into account other items that are in WM, eliminating them as response candidates? To address this question, an ideal-responder model that assumes perfect…

Purpose: Whilst beneficial, the use of evidence to improve teaching and learning in schools is proving difficult to achieve in practice. The purpose of this paper is to shed new light on this issue by examining the applicability of a model of rational behaviour as relates to the notion of evidence-informed practice (EIP). Specifically, exploring…

A statistical model for characterizing the growth patterns of data base utilization and for estimating future utilization levels of demand has been developed for information retrieval organizations. Illustrations of the model applied to a typical information retrieval organization are given and discussed. (5 references) (Author)

THE LOGIC AND METHOD FOR THE DEVELOPMENT OF A MATHEMATICAL MODEL REPRESENTING ASPECTS OF THE VOCATIONAL REHABILITATION PROCESS ARE PRESENTED. THE PROJECT GOALS INCLUDED BUILDING A CONCEPTUAL STRUCTURE WITHIN WHICH VARIOUS FACTORS INFLUENCING REHABILITATION OUTCOME COULD BE MORE CLEARLY UNDERSTOOD, AND PREDICTING SOME OF THE VARIATIONS IN OUTCOME…

The Cobb-Douglas model applied to value added as a function of labor, capital, purchases of information services, and purchases of other input is used to investigate the use of information by the industrial sector of Croatia, Yugoslavia. It is concluded that less than an optimal amount of information resources is being used. (13 references)…

The strongest path in the information-energy model is the direct linkage between information and bureaucratic development. (Author/IRT)

The data collected in higher education research are not always quantitative or continuous. Statistical methods using the log-linear model provide the institutional researcher with a powerful set of tools for addressing research questions when data are categorical. (Author/MSE)

A communication model suggests that in almost all cases where dissemination and utilization of knowledge has taken place, one or more of seven general factors can be identified as having been active in aiding the phenomena. The proposed factors are: linkage, structure, capacity, openess, reward, proximity, and synergy. In order to use this model…

Indicates that citation data conform to the Brookes model, that a scientific journal which is used as an archive ages slowly, and that one which supports a research front ages quickly--aging being dependent not only on the material, but on the user. (Author/SW)

Proposes a model for technical journal deselection based on the Bradford law of distribution. The model's operational prescriptives, characteristics of the Bradford distribution in the field of pediatrics, and relevance to collection management are discussed. (42 references) (KRN)

A statistical analysis was performed to test the hypothesis that, if profit-maximizing firms have limited information about the general productivity of new workers, they may choose to use easily observable characteristics such as years of education to discriminate statistically among workers. Information about employer learning was obtained by…

The relationship between employer learning and statistical discrimination was explored through a statistical analysis that included a test for statistical discrimination or "rational" stereotyping in environments where agents learn over time. The test is used to study the working hypothesis that, because firms have only limited…

The findings of a study undertaken at the University of Pittsburgh in 1975 to determine the extent of materials use and the full cost of such use in the university library system are presented in this 272-page report. Intended to serve as a foundation for improved acquisitions policies, this report covers circulation and in-house use of…

A pilot project was designed to test the efficacy of profiling welfare recipients and referring them to welfare-to-work services targeted toward their specific work histories and skills. The general framework of Michigan's Work First program was used to illustrate how profiling can be designed and administered. A profiling model was proposed that…
