Qualitative Analyses

Although a mature technique, Raman spectroscopy remains not widely used as a routine analytical technique. The advantages of Raman spectroscopy, such as minimal sample preparation and relatively uncomplicated spectra, combined with technical advances, including more stable diode lasers, higher quality filters, and better polychromators and array detectors, have led to a renaissance in sensitive and versatile Raman spectrometers. The lack of appropriate databases for routine analysis, which represents the last barrier to the technique's widespread use, is beginning to be overcome, as described in this review.

User Tasks

A methodology and a computer based program for testing documentation organization and location aids (tab-dividers, indices, tables of content and headings) was developed and used to aid the design and evaluation of documentation. The methodology and program allow computer analogs of documents to be tested before they were actually produced (based on detailed outlines). The documentation testing program presents the test subject a series of goal oriented user tasks. The subject then selects from a set of books and uses the existing location aids or paging to locate the heading that contains the information required to accomplish the task. The program automatically records use of the table of contents, tab-dividers, and index as well as the heading under which the subject believes the information will be found. The subject is allowed to make changes and additions to the tables of content, the index, and main body headings as the test progresses. The program runs in two modes. One mode provides feedback to the test subject on whether the final location is correct and tests how rapidly information can be found. Another model provides no feedback on the correctness of the locations and is used for developing models for the documentation based on user search paths and information content assumed to be under headings. The program has been used to evaluate documentation for a large computer operating system (HP-UX, a variant of UNIX*) and the results show promise.

Dr. Robert S. Harnack and associates have developed a revolutionary method designed to eliminate the disadvantages, but to retain and improve the advantages of unit teaching. The electronic computer is applied to provide teachers with pre-planning suggestions from a large Computer-Based Resource Unit coded to the students' individual characteristics and objectives.
