This article analyzes the choice of tactics by armed groups. We claim this choice is largely determined by the capacity of the rebel groups to control territory. Groups that are not able to liberate territory remain underground and have to rely mainly on bombings. Groups with territorial control engage in guerrilla-like attacks in which there is a physical encounter with the enemy. This conjecture is tested and largely confirmed at three levels: a cross-sectional analysis of the distribution of tactics in 122 armed groups, using compositional data analysis; a geographical analysis of the distribution of tactics in the largest cities as opposed to the rest of the country; and a case study of Hezbollah.  相似文献

Safety perceptions of residents are often analysed through surveys and compared with factual crime developments. Using the Dutch city of Rotterdam as an urban context of improved crime levels, this article provides a critique on standardised surveys in the research of safety perceptions and its presupposed connection to factual crime. Contrasting survey results from the Rotterdam Safety Index with qualitative data from 64 in-depth interviews in four districts, the qualitative narrative contradicts findings from the survey and implies more nuanced and diversified policy responses to safety issues. Because of the tendency of surveys to connect safety perceptions to factual crime, their unsuitability to catch subtle perceptions and their inability to expose new viewpoints, we argue for de-quantification: a lesser dependency on—but not a repeal of—survey data in this area, supplemented by a periodic qualitative approach in the research of crime and safety information (qualitative monitoring).  相似文献

This article examines the policies implemented by both the Obama and Trump Administrations toward Cuba to evaluate the claim that the ‘Thaw’ of relations between Washington and Havana represents a significant change in US foreign policy toward the island nation. Despite the appearance that the change in policy is a fundamental shift, I argue that the changes in US policy toward Cuba under both Obama and Trump represent changes in the means for pursuing the same historical objectives pursued by the Washington for the past few decades. In other words, the overall strategy and objective of US hegemony in Cuba is the same, with the only change being the means for achieving these ends. The central implication of this is that the ‘Thaw’ in relations between Cuba and the US represents a new, more ‘consensual’ means to instigating the same objective of provoking American-orchestrated political, economic, social and ideological changes in the island nation.  相似文献

Nineteen Y-specific short tandem repeat (STR) loci have been amplified in 768 samples from the Iberian Peninsula in order to evaluate their usefulness in forensic casework. Two previously published multiplex reactions by Thomas et al. [Hum. Genet. 6 (1999) 577] (MS1, modified here: DYS19, DYS388, DYS390, DYS391, DYS392 and DYS393) and by Ayub et al. [Nucl. Acids Res. 28 (2000) e8] (CTS: DYS434, DYS435, DYS436, DYS437, DYS438 and DYS439) plus a novel one reported here (EBF: DYS385, DYS389, DYS460, DYS461, DYS462 and amelogenin) have been used. DYS385, DYS439 and DYS391 were the most informative loci with allele diversities of 0.7997, 0.6683 and 0.5940, respectively. A total of 635 different haplotypes were observed, of which 573 (90.24%) were found in single individuals. The overall haplotype diversity was 0.9988 and that obtained by each multiplex system was 0.9812 for EBF, 0.9292 for MS1 and 0.9089 for CTS.  相似文献
