This article argues that political learning with regard to civil-military relations in Chile has proved an obstacle to democratization. In the postauthoritarian period, both the armed forces and political parties have referred to history when considering civil-military reform, especially with regard to how to avoid a repeat of the conflict of the Unidad Popular period. Meanwhile, the military also utilizes the Spanish example when resisting changes it feels are inimical to its interests. The 'lessons' each takes from the past directly influence political strategies and the overall result is that while civilian rule continues, democratic civil-military relations are not necessarily advanced.  相似文献

This study investigates the types of factors which can lead to government acquisition, or the “spin-in” of bio-defense technologies from small bio-technology firms. Empirical findings suggest that for small biotechnology R&D firms desiring to increase “spin-in” technology transfer, there appears to be two distinct and important influence groups—the scientific community within federal agencies, institutes, and centers, and the more managerial, policy-oriented decisions makers. We found that personal communication and networking appear to be the primary factor that leads to a successful technology transfer, however, the form and substance of personal communication and networking will differ between the two influence groups.  相似文献

As foreign secretary from November 1924 to June 1929, Austen Chamberlain dominated British foreign policy. Central to his diplomatic strategy was the maintenance of the European balance of power and, in this circumstance, pursuit of a leadership role for Britain within the League of Nations. The foundation upon which Chamberlain based his European strategy lay with his determination to have Britain play the vital role of stabilizing relations between France and Germany, whose mutual antipathy after the Great War, compounded by the severity of the Treaty of Versailles, threatened continental security. By October 1925, his work bore fruit with the conclusion of the Locarno agreements. For the remainder of his tenure at the Foreign Office, Chamberlain used Locarno - and Germany's membership in the League that was part of that settlement - as the diplomatic mechanism to underwrite his strategic conception of the balance of power. This article addresses the neglected issue of the strategic base of Chamberlain's European policy and addresses three criticisms of his record as foreign secretary.  相似文献

Three case histories of men who suffered posttraumatic stress disorders after committing homicides are presented. These men were relatively young and had chaotic childhoods and minimal criminal histories. Each had killed a woman with whom he had a significant but intensely turbulent emotional relationship. The killings all occurred during altered mental states that were unrelated to the use of drugs or alcohol. The clinical significance and some of the medicolegal implications of this phenomenon are discussed.  相似文献

In accordance with Puppe's rule, the analysis of skull fractures may provide evidence on the sequence in which multiple blunt injuries of the skull occurred. In cases of multiple gunshot wounds of the skull determination of the sequence in which the gunshot wounds took place is much more difficult. In some cases, however, analysis of the skull fractures here can also allow the order in which gunshot wounds occurred to be established.  相似文献
