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

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

Recent formal models of legislatures have proved that equilibrium outcomes are extremely unlikely without either (1) extreme restrictions upon preferences or (2) constraints upon the agenda. The implication is that constant instability or dictatorial manipulation is the norm in politics. This paper argues to the contrary, that legislatures (and other political processes) are characterized by some regularities, and that equilibrium models are the appropriate technique to use in describing these regularities. Examples from economic theory are used to illustrate this principle. The assumption of equilibrium is methodological, committing the researcher to develop models that have specific empirical implications. Using analogies from the economic theories of general equilibrium, oligopoly, and demand revealing processes, some potentially fruitful means of developing equilibrium political models are described. Assuming that legislators may freely make binding contracts has both empirical and normative advantages. Finally, institutional restrictions on legislative agendas may assure equilibrium. These include ‘constitutional’ rules, agreements to share ‘pork barrel’ projects evenly, limitation of committees to specific policy arenas, and the election of leaders who then determine the voting agenda.  相似文献

The energy industry, especially the petroleum, is critically important to today's society. This industry has historically been accused of being a “good old boy” network that is extremely reluctant and slow to accept technology and change. A closer analysis of the industry shows that it is highly fragmented consisting mostly of firms who operate in only a limited number of functional areas. The analysis also shows that there are many critical current and future problems which could be addressed with technology from any diverse disciplines and industries. Case analyses of existing technology flow through to successful utilization by the petroleum industry describes the technology transfer process and the role played by the different firms inside and outside the industry.  相似文献

A micromethod based on the absorption elution technique was shown to be applicable to the detection of M and N blood groups of dried bloodstains on cotton cloth. Each antigen M and N was tested using two different types of antisera. Two hundred different bloodstains, stored up to six months, were analyzed. Conclusive results were obtained for M typing on 2.5-mm-long bloodstained threads. For N typing, some cross-reactivity of homozygous M stains with anti-N sera was observed. This may be explained by the structure of the M and N antigens on the red cell membrane.  相似文献
