I present a model of the interaction between a government, a terrorist organization, and potential terrorist volunteers in which, as a result of an endogenous choice, individuals with low ability or little education are most likely to volunteer to join the terrorist organization. However, the terrorist organization screens the volunteers for quality. Consequently, the model is consistent with two seemingly contradictory empirical findings. Actual terrorist operatives are not poor or lacking in education. And yet lack of economic opportunity and recessionary economies are positively correlated with terrorism. The model also endogenizes the effect of government counterterrorism on mobilization. Government crackdowns have competing effects on mobilization: they decrease the ability of terrorists to carry out effective attacks (making mobilization less attractive), and they foment ideological opposition to the government and impose negative economic externalities (making mobilization more attractive). This provides conditions under which government crackdowns increase or decrease mobilization.  相似文献

This article examines processes of identity formation in Darfur,now part of the Republic of Sudan, over the last four centuries.The basic story is of four overlapping processes of identityformation, each of them primarily associated with a differentperiod in the region's history: namely, the ‘Sudanic identities’associated with the Dar Fur sultanate, Islamic identities, theadministrative tribalism associated with the twentieth-centurySudanese state, and the recent polarization of ‘Arab’and ‘African’ identities, associated with new formsof external intrusion and internal violence. It is a story thatemphasizes the much-neglected east-west axis of Sudanese identity,arguably as important as the north-south axis, and redeems theneglect of Darfur as a separate and important locus for stateformation in northern Sudan, paralleling and competing withthe Nile Valley states. It focuses on the incapacity of boththe modern Sudanese state and international actors to comprehendthe singularities of Darfur, accusing much Sudanese historiographyof ‘Nilocentrism’, namely, the use of analyticalterms derived from the experience of the Nile Valley to applyto Darfur.  相似文献

The purpose of this paper is to measure and explain variations in productive efficiency of municipal governments in Belgium. Technical efficiency is evaluated using a non-parametric method based on the Free Disposal Hull (FDH) reference technology. We first calculate input, output, and graph Farrell efficiency measures for a cross-section of all 589 Belgian municipalities. In a second stage of the analysis we explain the calculated differences in efficiency in terms of variables related to the structural characteristics of municipalities and to the institutional environment.  相似文献

Interpreting a myocardial inflammation as causal, contributory or as of no significance at all in the cause of death can be challenging, especially in cases where other pathologic and/or medico-legal findings are also present. To further evaluate the significance of myocardial inflammation as a cause of death we performed a retrospective cohort study of forensic and clinical autopsy cases. We revised the spectrum of histological inflammatory parameters in the myocardium of 79 adult autopsy cases and related these to the reported cause of death. Myocardial slides were reviewed for the distribution and intensity of inflammatory cell infiltrations, the predominant inflammatory cell type, and the presence of inflammation-associated myocyte injury, fibrosis, edema and hemorrhage. Next, the cases were divided over three groups, based on the reported cause of death. Group 1 (n = 27) consisted of all individuals with an obvious unnatural cause of death. Group 2 (n = 29) included all individuals in which myocarditis was interpreted to be one out of more possible causes of death. Group 3 (n = 23) consisted of all individuals in which myocarditis was reported to be the only significant finding at autopsy, and no other cause of death was found. Systematic application of our histological parameters showed that only a diffuse increase of inflammatory cells could discriminate between an incidental presence of inflammation (Group 1) or a potentially significant one (Groups 2 and 3). No other histological parameter showed significant differences between the groups. Our results suggest that generally used histological parameters are often insufficient to differentiate an incidental myocarditis from a (potentially) significant one.  相似文献

This article examines the medical literature published in France in the period 1800–1870 on the subject of puberty and menstruation to argue that, in conjunction with the extension of school life for bourgeois girls, the period saw the emergence of a distinctive conception of feminine adolescence that pre-dates the better-known concepts articulated in the late nineteenth century. It goes on to look beyond the scientific discourse to ask what impact this new medical understanding had on the management of girls’ puberty, examining first the way it affected school practice, before using a detailed case-study of the life of Solange Dudevant to highlight the ways in which medicalised understandings of puberty and menstruation co-existed with other forms of knowledge.  相似文献

The arrest in May 1942 of Liao Chengzhi – a CCP spy chief as well as the son of a celebrated KMT elder assassinated in 1925 – is considered a Big Case in China. Using the original KMT case file on Liao Chengzhi, van de Ven describes how the KMT's secret service turned the Jiangxi Provincial Committee and then arrested leading members of the CCP in south China and thereby eliminated its organization there. The article further uses letters by prominent CCP and KMT personalities involved in the case to suggest the existence of a revolutionary aristocracy bound by personal relations and with an elite code of conduct. When the political will was present, members of this elite deployed their personal connections in the search for solutions to complex political problems.  相似文献

The fundamental distinction between Ricardo and Marx is once more examined, chiefly with reference to the current spread, among some leftwing economists, of a neo-Ricardian school. So a crucial point seems to be the particular meaning, which is quite a-Ricardian, of the first section of the Capital. Anyhow, this section is often misunderstood, because of its difficulty, and its philosophical form.  相似文献
