There is no shortage of warnings concerning the hazards of excessive ambition in consciously-pursued public policy. In the light of these cautions, this paper considers the appropriate ambitions for policy design. The critics have missed the target. There is no need to fear ambition in policy design, provided that openness in communications about policy is secured. 相似文献

Intramyocardial small vessel abnormalities are not commonly recognized. The best known abnormality is fibromuscular dysplasia involving the sinoatrial or atrioventricular nodal arteries. Small vessel disease has been reported as an isolated cardiac anomaly in individuals with sudden death, and may also be associated with other cardiac conditions including hypertrophic cardiomyopathy and mitral valve prolapse. The nature of the association is unknown, and the mechanism causing sudden death is sometimes obscure. We describe pathological changes of the intramyocardial small vessels of three individuals with sudden death. Abnormalities involved small vessels at different levels. In all the cases, the abnormalities were thought to have caused or contributed to the individual's death. The possible mechanisms of this are discussed. 相似文献

The purpose of this highly speculative article is to assess a broad range of possible developments in Cuba over the next five
to seven years that could directly and adversely affect U.S. interests. By definition, therefore, it does not provide equal
treatment to more optimistic and, salubrious scenarios. A key assumption is that the Cuban economy will not sustain a strong
rebound to high levels of growth. Specific observations about how security challenges might impact certain U.S. government
activities are also included according to the article’s terms of reference. No attempt is made to assign numerical or other
probabilities to the counterfactual cases discussed. Finally, the future time frame examined includes treatments of a continuation
of Fidel Castro's regime as well as the emergence of one or more successor governments.
