We develop a model of the peace dividend and use it to predict the fiscal consequences of a reduction in the demand for military spending. The model is based on the assumption that the political process responds to political demands and costs in a way that maximizes net political benefits. The predictions of our model on how a peace dividend will be allocated over nonmilitary spending, tax relief, and deficit reduction is tested against the experience of eight major wars in United States history.  相似文献

For much of the nineteenth century, Canadian education-related international activities resided outside the realm of traditional diplomacy. This situation was exacerbated by Canada's colonial link with Great Britain. Obstacles that prevented educationalists from playing a more substantive role in diplomacy were local, imperial, and ecclesiastical in origin. Educational activities were also a tool in the service of governments in the era between the zenith of British Imperialism in the 1890s and the founding of the United Nations in 1945. In the post-1945 era there was greater collaboration between the federal Ministry of External Affairs and provincial ministries of education. Education also emerged in the late twentieth century as part of the new diplomacy. A flowering of new international governmental organizations dedicated to furthering creative diplomacy brought new energy to this field.  相似文献

A case of kidnapping involving the concept of paternity testing is described. The couple arrested and charged with kidnapping stated the child in their possession was their biological daughter. Serological tests were performed on liquid blood samples in an effort to determine if the couple could have been the biological parents of the child. Two genetic inconsistencies were discovered in the 15 blood marker systems analyzed.  相似文献

An important problem in the political economy of the UK is that the disparity of unemployment rates across its regions is much more marked than the corresponding dispersion of wage rates. One possibility is that this is due to the attitude of trade unions to their members in different regions. If unions wish to preserve parity between members in different regions then they will value wage equality between regions over and above wage levels. This may then persuade them to overlook inter-regional productivity differences in setting wages. The price that low-efficiency regions will then pay for this desire for wage equality is higher unemployment rates.Much of the research for this paper was carried out while the author was visiting the Trade Union Economics Research Institute (FIEF), Stockholm in 1989. An earlier version of this paper was presented at a seminar there and the author is gratefully to Villy Bergstrom, Paul Chen, Douglas Hibbs, Eva Udden-Jondal and other institute members for several useful comments. Comments from Kevin Lee, John Spencer and an anonymous referee have also substantially improved the paper. The usual disclaimer applies.  相似文献

A dissecting intramural haematoma of the coronary artery is an infrequent cause of sudden and unexpected death. Most cases are women and in a significant number of these women, the haematoma occurred at term to 80 days postpartum. Because the intimal rupture and communication with the lumen were not found in most of the cases, the site of rupture has been considered to be a vasa vasorum. The authors report on a case of one woman who was at a later postpartum period (106 days). The microscopic finding of the dissected coronary artery revealed two intimal tears in a section. The case showed that the dissecting intramural haematoma of the coronary artery is caused not only by the rupture of the vasa vasorum but also by the rupture of the intima.  相似文献

The purpose of this investigation was to identify inmate personal and demographic data that may be used to further define or profile persons with a greater likelihood of being at risk for serving a jail sentence. This study was explorative. The survey administration was similar in format to that conducted by the U.S. Department of Justice. Chaplains were used as survey proctors. Pilot studies were conducted to determine the suitability of survey content. Surveys consisted of 172 items. Subjects included four hundred inmates: males comprised 88.75 percent of the sample, Caucasians 58.25 percent, Blacks 37 percent, Hispanics 3.25 percent and other 1.5 percent of the sample. Respondents ranged in age from 15 to 64 years with an average age of 30.3 years. Less than two percent of the contacted inmates refused participation in the survey. Results are presented for demographic data, select legal/criminal data, select drug and alcohol use data, employment data, health, parent/family data, education data, social data, and “other”.  相似文献
