Federal Reserve officials and many observers of monetary policy claim that the implementation of monetary policy has become more “transparent” over the last decade. This paper argues that monetary policy is anything but transparent because multiple and conflicting goals for monetary policy still exist, precise targets for these goals never are defined, the Fed’s economic model is unknown to the public and, by confusing its apparent intermediate target variable with its true policy instrument, actions taken to be stimulative can be contractionary and vice versa.  相似文献

Two cases of suicide with bandsaws, undertaken by workers in carpenters' workshops are reported and discussed. Their choice of this method was based on the fact that they knew how dangerous such machines were. Both cases were watched by witnesses, who could not intervene due to the speed of the events. It was possible to exclude accident or homicide.  相似文献

In a re-examination of 334 fatal multiple car accidents, without any reasonable explanation besides possible intoxication, 205 drivers were found responsible for the accident. Twenty-one of these accidents happened between midnight and 0600 h and 11 of the drivers were found to be intoxicated with a blood/alcohol content (BAC) of more than 0.080%. The remaining 184 accidents took place during the rest of the day and 55 drivers were intoxicated. By comparing this apparent over-representation of intoxicated drivers in night-time accidents with that of a control group of no less than 15,923 drivers, it was possible to convert this over-representation into an under-representation. This decline in accidents while under influence seems to indicate another human accident factor specific to night-time traffic. It is concluded that fatigue is an overlooked but most obvious cause of otherwise unexplainable accidents in the night-time traffic.  相似文献

Fatal traumatic thrombosis of the left internal carotid artery occurred in a 38-year-old man following minor blunt cervical trauma during an altercation. There was no external injury observed on the head, face, or neck. Neurologic deficit developed soon after the injury, which progressed to right hemiplegia. His condition deteriorated and he expired on the sixth hospital day. The gross and microscopic findings of the internal carotid artery are presented and the significance of minor cervical blunt trauma and the possible mechanism for the vascular lesion are discussed.  相似文献

The authors describe a special case of suicide, committed by a self-constructed nailgun. The inshot-wound, localized in the mouth, primarily remained undiagnosed. The patient survived two weeks and died of pulmonary embolism.  相似文献
