This article examines the reassessment of U.S. strategy that Dwight D. Eisenhower directed after replacing Harry S. Truman in the White House in January 1953, as he worked to bring the Korean War to an end and then confronted the problems remaining in its aftermath. Despite much of the rhetoric of the early Eisenhower administration, the outcome of that reassessment fit more closely the objective of containment than key strategic formulations of its predecessor. Why was this so? How did the orientation apply to ending the war in Korea and sustaining the U.S. position there and elsewhere after the armistice? What insights, if any, do the process of reassessment and its outcome provide for the present? Answers to these questions serve to emphasize the dynamic and contingent nature of American strategy in the early Cold War and the importance of flexible, engaged leadership in the White House.  相似文献

Administrators of law enforcement agencies are increasingly caught up in conflicts between demands to increase educational standards for police officers and the need to justify those increased standards based upon job relevance. On the one hand, national commissions suggest four year degree prerequisites for entry level into police work; on the other hand, police administrators are reluctant to impose rigid higher educational requirements because of possible negative ramifications such as a limited recruitment pool, rapid officer turnover, and court mandates to prove the job relevance of a college education. This study addresses these concerns by reviewing current empirical studies and relevant court decisions which add insight into this topic and which will, hopefully, assist administrators in making decisions regarding college educational requirements for hiring and promotion.  相似文献

Researchers are frequently interested in estimating the elapsed time until the occurrence of an event, such as an arrest following release from prison, dissolution of a marriage, and death following the onset of a disease. Estimation is often hindered by the occurrence of a competing event, which prevents the event of interest from being observed, and by limited follow-up periods. A parametric procedure developed in this paper is suitable for dealing with nonrepeatable competing events when the events are correlated and when independent righthand censoring also exists. Weak distributional assumptions are accommodated by using a Box-Cox transformation and by explicit modeling of heteroscedasticity. The procedure is applied to data pertaining to failure on probabation and parole.  相似文献
