Multiple deaths from argon contamination of hospital oxygen supply   总被引:1,自引:0,他引:1  
During the course of routine hospital surgical procedures, three patients lapsed into hypoxic cyanosis. Two expired immediately, another after four days of coma. Investigation of the hospital's central liquid oxygen tank revealed that it had been refilled recently and was labelled both "oxygen" and "argon." Mass spectrometric analysis of gas sampled from the questioned tank revealed a predominance of argon. A discussion of the sampling technique, method of analysis, role of the criminalist, and causes of this accident is presented.  相似文献

System of cities dynamics in newly industrializing nations   总被引:1,自引:0,他引:1  
Rapid industrialization in such countries as Korea, Malaysia, and Taiwan suggests that the complex functional structures of cities in the periphery may appear early in development. This paper proposes a 4-stage framework for the dynamics of a system of cities in a developing country undergoing industrialization and encompassing both nonindustrial and industrial development. The synthesis is assessed with evidence from the newly industrializing Asian nations of Korea, Malaysia, and Taiwan. The 4 stages of cities' industrial change include 1) increasing primacy with industrial satellites, 2) increasing primacy with industrial satellites and nodal towns on a transport network, 3) rapidly increasing primacy with rapidly growing industrial satellites and nodal towns on the transport network, and 4) decreasing primacy with slowly growing industrial satellites and rapidly growing peripheral industrial towns. The 4-stage synthesis suggests that economic development in the periphery may occur even while the primate city maintains its hegemony over control and coordination functions. Peripheral industrial growth does not challenge this hegemony. The growth of industrial cities is, instead, part of a process of regional specialization in which the low cost labor in the periphery becomes an attraction for industry. These stages are not inevitable. Government efforts are necessary to develop rural areas in terms of social improvements (education and health), capital infrastructure (transportation and utilities), and fair payments to farmers for their outputs. These seem to be the lessons learned from the industrialization process in Korea, Malaysia, and Taiwan.  相似文献

The law governing the obligation of therapists to report their patients' previous criminal acts was reviewed. Most often, discussions of this subject fall under the general category of "misprison of a felony," that is, the presumed general obligation of all citizens to report felonies that come to their attention. Review of federal law revealed that the courts have consistently interpreted the federal misprision statute as requiring active concealment of a crime, not a mere failure to report, in order to convict for the offense. State law is more diverse. Only one state has a general misprison statute labeled as such, and several states have recently repealed such statutes. The strong trend in states without statutes is to reject misprison as a common law crime, because of its incompatibility with modern notions of justice. Most states, however, have limited reporting statutes, such as for child abuse or gunshot wounds, that impose similar obligations. Therapists' reporting of past crimes may be affected by clinical and ethical concerns, as well as by obligations to protect future victims. In almost all jurisdictions, however, the fear of prosecution for failure to report a past crime should not be a factor in deciding on a course of action.  相似文献
