The latest revisionism in the study of political tolerance has produced some of the most provocative well-designed research in the field of political science. In particular, the work by Sullivan, Piereson, and Marcus offers one of the most fully specified and rigorously executed models of public opinion formation. Yet this contemporary revisionism is flawed. This paper argues that these researchers misconceptualize tolerance, that this misconception contaminates their measurement process, that the resulting model is misspecified, and that the political conclusions offered are not supported in fact or principle. More generally this paper argues that the field of public opinion as a whole has been trapped by limited conceptions about the nature of cognitive constraint and by simplistic and inadequate methods for measuring and identifying this constraint. To remedy this, a developmental measure of cognitive moral stages is fashioned along lines suggested by Kohlberg. This measure satisfies a number of tests for both validity and reliability and appears to be one of the most powerful predictors of tolerance and intolerance — if not the most powerful single predictor. 相似文献

The policy sciences have advanced in the past by introspection, and there appears to be a need for a return to such self-conscious examination of the field of inquiry. A design orientation offers a useful framework for such an examination. It requires reconsideration of some of the fundamental premises of policy inquiry. This article explores what impact design might have on the conventional process framework and then proceeds to discuss the development of a design perspective. 相似文献

The level of degradation of DNA as a means for determining the time of death has been proposed as a valid adjunct to the classic thanatochronologic methods. The twofold aim of this work was to determine which organ might reveal both a correlation between the percentage of degradation of the DNA and the time lapse since death, and would be easiest to sample and yield the most reproducible results even in technically unfavorable situations such as on-the-spot investigations at the scene of death. A comparison of the spleen, blood, and liver showed that hepatic tissue best meets these specific needs because it shows a virtually linear correlation between the time elapsed since death and the level of degradation of the DNA, and it can easily be sampled at the scene of death by use of a common biopsy needle. 相似文献
