What is illegal behavior? An intuitively plausible answer is that illegal behavior is behavior which the government discourages by the use of coercion. Although such coercion theories are generally out of favor today, the usual objections to such a theory can be plausibly answered, and moreover the theory has significant advantages over other ways of understanding the notion of illegal behavior. 相似文献

This article discusses alternative promotion strategies that public policy makers can use to increase the effectiveness and efficiency of technology transfer programs. Three transfer strategies are described; the passive, the role-directed, and the organization-directed strategies. Factors influencing the selection of one of these transfer strategies by policy makers are considered in detail. 相似文献

When random assignment fails: Some lessons from the Minneapolis Spouse Abuse Experiment 总被引:1,自引:0,他引:1
Richard A. Berk Gordon K. Smyth Lawrence W. Sherman 《Journal of Quantitative Criminology》1988,4(3):209-223
In this paper, we consider what may be done when researchers anticipate that in the implementation of field experiments, random assignment to experimental and control groups is likely to be flawed. We then reanalyze data from the Minneapolis Spouse Abuse Experiment in a manner that explicitly models violations of random assignment. As anticipated, we find far larger treatment effects than previously reported. The techniques developed should be useful in a wide variety of settings when random assignment is implemented imperfectly. 相似文献

We have shown first, that if the electoral college was abolished the theoretically measured power of voters would increase and second, that in presidential elections the measure of voting power used does in fact have a highly significant impact on the decision as to whether or not to vote. Thus, the analysis predicts that the abolition of the electoral college would have a significant impact on voter participation. From a policy viewpoint, if we view participation in elections as desirable, this could be used as an argument in favor of direct election of the president. From a scientific viewpoint, we are able to make a strong and unambiguous prediction about the results of a (possible) future event from theoretical considerations. If the electoral college should be abolished, it will be possible to test our predictions. In addition, we have provided a further test of the rational behavior view of electoral participation and have shown that this model applies to presidential elections. Finally, we have shown that the theoretical measure of voting power does predict actual behavior. 相似文献

In a variety of settings, procedures that permit predecision input by those affected by the decision in question have been found to have positive effects on fairness judgments, independent of the favorability of the decision. Two major models of the psychology of procedural justice make contrary predictions about whether repeated negative outcomes attenuate such input effects. If such attenuation occurs, it would lessen the applicability of procedural justice findings to some real-world settings, such as organizations, where procedures often provide repeated negative outcomes. The present laboratory investigation examined the procedural and distributive fairness justments produced by high- and low-input performance evaluation procedures under conditions of repeated negative outcomes. Thirty-five three-person groups of male undergraduates participated in a three-round competition. Groups either were or were not allowed to specify the relative weights to be given to two criteria used in evaluating their performance. All groups received negative outcomes on each of the three rounds. A second experimental factor varied whether or not the group learned after losing the second round that it could not possibly win the third and final round of the competition. Measures of procedural and distributive fairness showed that the high-input procedure led to judgments of greater procedural and distributive fairness across all three rounds. The input-based enhancement of fairness occurred regardless of whether reward was possible. The implications of these findings for theories of procedural justice and for applications of procedural justice to organizational settings are discussed. 相似文献
