Nancy Cochran 《Policy Sciences》1980,12(2):113-129
In considering the efficacy of program evaluation researchers have not put language in proper perspective. They have not acknowledged that information gained from applied research is partly determined by situational factors, that language is selective and goal-oriented, justifying activity as often as it describes it, or that some important action cannot be expressed. The importance of language distinguishes applied social assessment from the natural science models of research from which it was derived. Examples from a wide range of applied situations are used to illustrate that, as an anticedent-consequent model of objective quantified assessment, evaluation is also inconsistent with the complex, resourceful, emergent social processes it is intended to measure. Three alternatives to quantification are discussed to illustrate interventions that may be made when the disadvantages of program evaluation outweigh the advantages.Preparation of the paper was supported by National Institute of Mental Health post-doctoral training grant 5T222-MH00180.

A meta-analytic review of the weapon focus effect 总被引:7,自引:0,他引:7
Nancy Mehrkens Steblay 《Law and human behavior》1992,16(4):413-424
This meta-analytic review examined 19 tests of the weapon focus effect—the hypothesis that the presence of a weapon during
commission of a crime will negatively affect an eyewitness's ability to later identify the perpetrator. A significant overall
difference between weapon-present and weaponabsent conditions was demonstrated, with weapon presence leading to reduced identification
accuracy. Overall, the size of the effect was small (.13) for the dependent measure of lineup identification and moderate
(.55) for feature accuracy. Discussion focuses on those factors that appear to mediate and facilitate the weapon focus effect.

The effect on juror verdicts of judicial instructions to disregard inadmissible evidence was evaluated using meta-analysis. One hundred seventy-five hypothesis tests from 48 studies with a combined 8,474 participants were examined. Results revealed that inadmissible evidence (IE) has a reliable effect on verdicts consistent with the content of the IE. Judicial instruction to ignore the inadmissible evidence does not effectively eliminate IE impact. However, if judges provide a rationale for a ruling of inadmissibility, juror compliance may be increased. Contested evidence ruled admissible accentuates that information, resulting in a significant impact on verdicts. Suggestions for how the courts may mitigate the impact of inadmissible evidence more effectively are discussed. 相似文献
