A Waste of Time? (Private Rates of Return to Higher Education in the 1990s)

Since 1990, there has been considerable debate concerning the benefits of the expansion of higher education and the appropriate way to fund such an expansion. This paper demonstrates that three factors are decisive to the individual contemplating higher education: national economic growth; the relative earnings of graduates and non-graduates; the difference between the average and the marginal student. The results, of analysis based on rates of return, reaffirm the view that a proportion of the costs involved in higher education can be transferred to the graduates themselves in the form of loans. However, there appear to be limits to the costs that can be transferred if all students are to judge that undergraduate study is a worthwhile proposition. Notwithstanding this, most students could be lent more income to study than is now the case and indeed an average student would be advised to take any loans despite the greater debt. Marginal students, however, are making a risky private investment and, therefore, any decisions to further expand may result in students not taking up the places.     

Impact of end-user search training on pharmacy students: a four-year follow-up study.

The Alfred Taubman Medical Library at the University of Michigan has offered instruction in online literature searching to third-year pharmacy students as a component of the course "Drug Information and Scientific Literature Evaluation" since 1983. In the spring of 1989, a follow-up study was conducted to assess the impact of instruction on four classes of graduates. Of a pool of 151 graduates, 90 (60%) responded to a mailed questionnaire on their use of information and computerized literature searching. The respondents were divided into four subgroups: end-user searchers, users of intermediaries, end users who used intermediaries, and those who did not use computerized literature search systems. Seventy-two percent of the respondents used some type of computerized literature searching, and 42% performed their own searches. The four subgroups differed in general computer use, familiarity with MEDLINE search terminology, information use, reasons for using or not using literature searching, and characteristics of searches (i.e., type, time frame, amount, and frequency). Training in end-user search systems appears to have had an impact on the continued use of computerized literature searching several years after the formal educational program.
