A probation risk-assessment instrument developed by the State of Wisconsin is receiving wide use throughout the nation and has been recognized by the National Institute of Corrections as part of a "model system." However, this has been done without extensive validation on populations other than Wisconsin probationers and parolees. The validity of the instrument for a population of City of New York probationers is assessed in this study. It was found that many of the variables contained in the instrument did not predict risk for the sample. On this basis. the validation of risk instruments before they are fully adopted is recommended. In addition, based on an analysis of split halves of our sample, the general weakness of statistically derived models is noted. 相似文献

As public resources become scarcer, private donations for capital projects and public services may become increasingly important. Modern donors, using the new philanthropy philosophy common now in the nonprofit sector, may desire more control over the use of their funding than in the past. This research examines the effects of private donations on capital decision making, and explores the balancing act required by public officials between best practices and private norms in this process. The study uses the city of Omaha, Nebraska case, where corporate and individual donors have made significant financial contributions for the construction of a convention center/arena and a baseball stadium. Findings include both costs and benefits of this approach, and may be beneficial for theory‐building related to this relatively unexplored topic, as well as for practitioners faced with similar needs and demands. 相似文献

This article focuses on the immigration‐related demands currently being placed on local police in the United States and the emergence of what we call a “multilayered jurisdictional patchwork” (MJP) of immigration enforcement. We report results from nationwide surveys of city police chiefs and county sheriffs and intensive fieldwork in three jurisdictions. The enforcement landscape we describe is complicated by the varying and overlapping responsibilities of sheriffs and city police, and by the tendency for sheriffs to maintain closer relationships with federal Immigration and Customs Enforcement (ICE) authorities. We conclude by reflecting on the implications of the MJP—for immigrants, for their communities, and for the evolving relationship between levels of government in the federal system. 相似文献

The initial encounters between Al Qaeda and the U.S. military taught both a series of lessons that reverberate across the battlefields of Afghanistan today. Both sides entered the fray with preconceived ideas of their enemy—ideas that disappeared on the battlefields of the Shahi-Kot valley. The United States was determined not to repeat the mistakes of the siege of Tora Bora. Their battleplan called for a lightning fast operation using highly mobile U.S. and Afghan forces to envelop the enemy, but failures of intelligence and the fog of war transformed Anaconda into a long, slow struggle against an often invisible foe. Al Qaeda had all the advantages of terrain and defense but was unable to cause the massive casualties they thought would drive the American invaders from Afghanistan. Both sides left the battlefield with valuable lessons that have prevented any similar encounters since silence returned to the Shahi-Kot. 相似文献
