Designing simple library hierarchies using linear programming

The problem of designing a best three level library hierachy is considered from two different points of view. While the form of the optimization problems obtained is a little more complicated, it is shown that at most the methods of linear programming suffice to solve them. Certain design parameters may be specified by the problem solver, and it is shown that the best objective function values are convex in these, thus making possible the extraction of considerable additional, useful information. Finally, the methodology is extended to longer hierarchies and found to be feasible if the length is moderate.     

FACTORS INFLUENCING THE SELECTION OF A GERONTOLOGY CERTIFICATE PROGRAM

Educational programs in academic gerontology with differing formats and requirements have emerged in a variety of educational institutions across Canada and the United States during the past decade. In 1986 and 1987, two gerontology certificate programs were initiated in Calgary, Alberta, Canada. One program is offered through the Faculty of Continuing Education at the local university, the other through the community college's Department of Nursing and Allied Health. Although both programs are multidisciplinary, they differ in their relative emphasis on theory, practice, and research.

The above and other differences were examined by a survey designed to probe why students from a variety of disciplines selected one of these programs over the other. It was hypothesized that variables such as preferred learning style, previous experience with specific types of educational facilities, and influence of peers and work setting would be factors influencing program selection. The results of this study lead to recommendations regarding the status of gerontological credentials in Canada and the need for students to be more aware of program choices.
