Switzerland's participation in the highly political Marshall Plan was considered the utmost commitment the West could expect from this neutral country during the unfolding Cold War. In military matters, though, the national doctrine seemed to be applied most rigidly. Indeed, the Swiss refrained from establishing substantial contacts with their direct neighbours as well as with the chief sponsors of European security. Neutrality, however, did not prevent the Swiss from entertaining uniquely British-oriented military relations, that culminated during the Korean war in a high degree of coordination of defence, wherein Field-Marshal Montgomery played a crucial mediatory role.  相似文献

Single-nucleotide polymorphisms of Y chromosome (Y-SNPs) are a class of markers of interest in forensic investigations, because many of them show regional specificity, providing useful information about the geographic origin of a subject or evidence under investigation. A first multiplex with 7 SNPs (M35, M89, M9, M170, M172, M45, M173), which occur in the basal branches of the phylogenetic tree and are able to assign a subject to known most frequent European haplogroups, was designed. SNP genotyping was accomplished by hot-start PCR with primers amplifying fragments between 96 and 136 nucleotides, minisequencing, and capillary electrophoresis of extension products. Ninety seven subjects of known geographic provenance were studied, of which 68 from Europe. Of these, 57 had mutations found more frequently in European haplogroups and 11 more frequent in Asian populations. Subjects from non-European countries were also examined and had haplogroups common in their regions of provenance. Experiments with low molecular weight DNA gave positive amplification from 1 ng of DNA for all seven SNPs.  相似文献

What explains the adoption of military innovations? In this article, we assess the empirical validity of adoption capacity theory by reconsidering one methodologically important case analyzed by Michael Horowitz: the diffusion of suicide terrorism. We show that, when addressing problems in Horowitz's research design, the case of suicide terrorism fails to support adoption capacity theory. We argue that, in order to account for the diffusion of this innovation, one needs to take into consideration the tactical incentives to overcome technologically superior enemies. The results of our quantitative and qualitative analyses suggest that terrorist groups fighting against very powerful states in terms of conventional capabilities are more likely to employ suicide attacks than those fighting against poorly equipped ones. Our findings are important because they provide systematic evidence in support of Kalyvas and Sànchez-Cuenca's argument that suicide terrorism is driven by tactical considerations and because they provide confidence in the external validity of Berman and Laitin's hardness of targets hypothesis. Our results also question Lyall and Wilson's finding that highly mechanized armies are inherently inadequate to win counterinsurgency operations. The superior conventional capabilities of a counterinsurgency army might in fact make traditional insurgent tactics ineffective and thus give insurgents an incentive to adopt suicide attacks.  相似文献

Material recovered from 374 fingerprints left by eleven laboratory workers on three different substrates (glass, wood, metal) at a standard pressure time of 30 s, with and without preliminary handwashing, was submitted to morphological, quantitative, and type analysis. Morphological and agarose-gel electrophoresis analysis showed that a non-negligible amount of epidermal corneal cells presented apoptotic alterations. The quantity of DNA recovered from fingerprints ranged between 0.04 to 0.2 ng, and in a significant number of experiments no DNA was detected. Handwashing reduced the amount of DNA recovered from fingerprints. The "shedder status" of the donor was a very important factor, causing inter-individual variations in the amount of DNA left by fingerprints. Spurious alleles from laboratory-based and secondary transfer contamination, stutters, and other artifacts described when analyzing low-copy-number DNA and capable of affecting correct profiles were observed.  相似文献

Since its introduction, colonoscopy has played an important role as a diagnostic, therapeutic, and screening tool. In general, colonoscopy is regarded as a safe procedure, but complications may occur. The most dreaded of these complications is colonic perforation. Bacteremia postprocedure may occur, and although it is not uncommon, it rarely results in clinically significant complications. Patients with IBD (inflammatory bowel disease) are a high‐risk population for bacteremia, which may leads to bowel wall overstepping by the bacteria. With regard to that, we report a fatal case of gas gangrene complicating colonoscopy polypectomy without bowel perforation in a healthy adult. To the best of our knowledge, only two other cases of retroperitoneal gas gangrene associated with colonoscopy polypectomy without bowel perforation have been described in international literature, but none of which was completed by a molecular biology analysis.  相似文献

The commitment of the EU to the external promotion of the respect for human rights allegedly distinguishes its foreign policy from that of traditional powers. Yet there is the perception that EU's statements are not always consistent with internal practices. This article analyses one set of EU's inconsistencies that has not been sufficiently studied: the discrepancy between internal and external human rights standards. The article focuses on the promotion and protection of freedom of religion or belief, which has become a priority of the EU's foreign policy. It is submitted that the EU's external position generally reflects values common to the Member States, but is sometimes contradicted by the practice of domestic authorities. The human rights standards identified in the EU's foreign policy may arguably serve as a reference for legal reform and the interpretation of fundamental rights in Europe.  相似文献
