A methodological note on mail survey response rates.
Five mail surveys of broadcast managers during the 1990s yielded consistently low response rates. Implications for research are discussed.

The Kogan Attitudes Toward Old People scale: is it time for a revision?
The Kogan Attitudes Toward Old People scale scale has been used in gerontological research for more than 35 years. Criticisms of the scale, including dated wording and response bias, have increased in the 1990s. Researchers must examine the scale and decide whether a revision is now necessary.

Television news and elderly persons.
Previous studies concerning elderly people have examined either use of all media by older adults or their depiction in television entertainment programs. What has been overlooked has been television news and its effects on elderly people. Careful research is needed to gauge this.

Scanning molecular sieve chromatography of interacting protein systems: nonlinear least-squares analysis of small zone experiments.
A simple routine for nonlinear least-squares analysis is applied to small zone scanning data, where calibration of the gel column requires the use of fully characterized markers of known molecular size. Application of nonlinear least-squares analysis eliminates the difficulty encountered because of scarcity of calibrating markers for gels whose porosities span certain size ranges by providing a sensitive measure of changes in molecular size of the interacting protein system, in order to determine the interaction parameters, size heterogeneity, and the centroid position for time difference chromatographic experiments.
