Washington's relationships with the “leveraged allies” preferred by realists—those countries that have little choice but to follow America's lead—have long been considered more reliable than in its relationships with the “natural allies” favored by idealists: prosperous, democratic nations that share the goals and interests of the United States. President Bush's foreign policy requires these natural allies, but many U.S. government officials are more wary. Uganda under President Museveni is a model “natural ally” candidate, with its relatively humane and democratic internal policies, but its greater capacity to act without American leverage, approval, or supervision is likely to worry realist career diplomats. 相似文献

Assessing the Effect of Batterer Program Completion on Reassault: An Instrumental Variables Analysis
The main objective of this paper is to investigate the utility of using the instrumental variables (IV) method to estimate batterer program efficacy, i.e., the program effect among batterers who complete batterer programs. This method takes account of possible confounding due to unmeasured traits of compliers and non-compliers. A structural model is used to estimate the impact of program completion on reassault using instrumental variables (IV) regression. Data on 640 batterers enrolled at three batterer programs are used. Results obtained from IV regression are compared with those obtained from a more traditional regression analysis. The results indicate that usual regression methods yield estimates of program effect that may be biased due to confounding by unmeasured batterer characteristics. Unfortunately, IV estimates may be unreliable due to failure of some of the assumptions on which they are based. If equations are adequately identified by the non-linear functional form used to estimate them, then IV results indicate that among a very select group of batterers, program completion significantly reduces the probability of reassault. The implications of confounding due to program non-compliance, program non-enrollment and attrition for future evaluations of batterer programs are discussed. 相似文献

This study reports findings from a study of nine juvenile drug courts (JDCs) from across the US. A quasi-experimental design, with one-to-one matching on possible confounders and sociodemographics, was used for the outcome assessment (n?=?1372). Baseline and outcome data were drawn from justice system records. Although there is variation across sites and, to some extent, outcomes, these JDCs were generally ineffective in reducing recidivism. Similar findings have emerged in other recent studies of JDCs. Given the results of this study and others, it is essential that juvenile courts work to improve the effectiveness of JDCs by increasing adherence to known principles of effective intervention. 相似文献
