This article argues that an Islamist militant group with a relatively homogenous ethnic make-up is more likely to be supported by those of the same ethnicity even if the group makes no reference to and even downplays the importance of ethnicity. Using survey data from an original survey carried out in Pakistan in 2013, with 7,656 respondents, this hypothesis is tested in a multiple regression analysis of support for the Pakistani Taliban. The results demonstrate that co-ethnicity between the respondent and the Islamist militant group is the most important predictor of support for the militant group.  相似文献

Scholars concerned with the formation of states, specifically the relationship between state formation and war, hold one of two positions. Some agree with Charles Tilly’s historiological conclusion that war is decisive for the establishment of stateness and specify key concepts, in order to explain presumed discrepancies between past and present. Others point towards the international sphere in its current form and advocate a ‘war breaks states’ perspective. This paper argues that both standpoints neglect the ‘sub-national’ level. While proponents of the ‘war breaks states’ thesis are missing para-sovereign zones of rule, supporters of the ‘war makes states’ approach take a juridical view of statehood and focus on ‘state strength’. The failed states paradigm guiding contemporary security and development policy hinders an adequate analysis of the actual situation on the ground. Discussing the shortcomings of failed states approaches and state formation theorising, the paper proposes a conceptualisation in terms of socio-political variation instead of a mere dichotomisation of order. Some conclusive questions are raised, indicating future research directions linked to the historical sociology of state formation.  相似文献

A simple model allowing an analysis of the interaction between economic policy decisions and rent-seeking by private agents competing for political influence, is developed. Rent-seeking may be of the directly unproductive type, requiring resources that are withdrawn from productive activities, or it may manifest itself as income transfers (corruption) to political decisionmakers. In the political-economic equilibrium of the model the extent of rent-seeking, economic policy decisions, income inequality, etc. are endogenously determined.  相似文献

Human blood is the body fluid most commonly encountered at crime scenes, and blood detection may aid investigators in reconstructing what occurred during a crime. In addition, blood detection can help determine which items of evidence should be processed for DNA-STR testing. Unfortunately, many common substances can cause red-brown stains that resemble blood. Furthermore, many current human blood detection methods are presumptive and prone to false positive results. Here, the developmental validation of a new blood identification test, Rapid Stain Identification™-Blood (RSID™-Blood), is described. RSID™-Blood utilizes two anti-glycophorin A (red blood cell membrane specific protein) monoclonal antibodies in a lateral flow strip test format to detect human blood. We present evidence demonstrating that this test is accurate, reproducible, easy to use, and highly specific for human blood. Importantly, RSID™-Blood does not cross-react with ferret, skunk, or primate blood and exhibits no high-dose hook effect. Also, we describe studies on the sensitivity, body fluid specificity, and species specificity of RSID™-Blood. In addition, we show that the test can detect blood from a variety of forensic exhibits prior to processing for DNA-STR analysis. In conclusion, we suggest that RSID™-Blood is effective and useful for the detection of human blood on forensic exhibits, and offers improved blood detection when compared to other currently used methods.  相似文献

The principles that behavior is strongly influenced by the behavior of friends, and that people select each other to be friends on the basis of common characteristics, are based in large part on the many studies of adolescents that found the behavior of friends to be similar. In most of these studies, subjects were asked to describe, the behavior of their friends, and this information was then related to subjects' reports of their own behavior. The research on adolescent smoking and drinking described in this paper departs from that tradition by including friend reports of friend behavior so that results based on the different sources for measuring friend behavior can be compared. Subject report of friend behavior is a stronger correlate, of adolescent behavior than friend report of friend behavior, but the two sources for measuring friend behavior produce the same correlations with subject behavior when using longitudinal designs and controlling for prior subject behavior. The findings are discussed in the context of theoretical and methodological considerations of peer influence and selection.This research was supported by grants from the National Institute on Alcohol Abuse and Alcoholism (AA04099) and the National Institute on Drug Abuse (DA02480) of the U.S. Department of Health and Human Services.Received his Ph.D. from Florida State University.
