What strategic logics underlie terrorist groups’ use of linked suicide attacks? Are the goals that groups seek to achieve when sending linked bombing teams somehow inherently different than when sending individual suicide bombers? To answer these questions, this article introduces three typologies of linked suicide bomber detonation profiles—simultaneous, sequential, and nonproximate—and theorizes why terrorist groups might view each type of linked suicide bombing to be preferable to deploying a single suicide bomber. Improvements resulting from using an individual attacker include: ensuring a higher likelihood of successfully hitting a given target (simultaneous detonations); causing more casualties than a single bombing (sequential-wave detonations); and engendering wider-spread shock and awe (nonproximate detonations). Drawing on an original dataset detailing the entirety of Boko Haram’s suicide bombing efforts from 2011 to 2017, we then examine the extent to which these linked bombing typologies do actually appear to successfully lead to an improvement over the deployment of single suicide bombers. While we find that sequential-wave and nonproximate suicide bombings demonstrate evidence of hypothesized improvements over the deployment of single suicide bombers, our data show that deploying simultaneous suicide attackers does not lead to higher efficacy at targeting when compared to the deployment of individual bombers. In attempting to account for this fact, we argue that Boko Haram’s simultaneous detonation teams likely fail to show an improvement over single-bomber attacks because they tend to be composed of what we call “unenthusiastic and under-trained” bombers: teams of often uncommitted women, and sometimes children, which it deploys in tandem in a bid to avoid individual defection and increase the likelihood of at least one detonation in an attack. We conclude by suggesting what the process of linked bombing reveals about both terrorist groups in general and Boko Haram specifically.  相似文献

Although survey data identify no significant predictor of intolerance among the Russian population, young people are considered to display heightened levels of ethnic intolerance and radical variants of xenophobia. Drawing on survey and semi-structured interview data from a study of patriotism among young people in two cities in the North-West region of Russia, this article explores the strength of ethnic self-identification and ethnically exclusive notions of Russianness and compares levels and forms of ethnic intolerance. Identifying that routine expression of xenophobic sentiments coexists alongside a commitment to principles of ethnic equality, the article considers what the ambiguities and contradictions in the articulation of intolerance tell us about how young people negotiate complex contemporary multicultural societies.  相似文献

This paper examines the way that women’s relationship to peace is constructed in international institutions and international law. It identifies a set of claims about women and peace that are typically made and considers these in light of women’s experience in the conflicts in Bougainville, East Timor and the Solomon Islands.

As child support debt owed nationally persists at enormous levels, both noncustodial parents and the custodial families who are not receiving support suffer significant hardships, and states are forced to expend greater resources on collection and enforcement efforts. This paper presents findings from an evaluation of a demonstration program developed to help noncustodial parents with large child support debts reduce their debt while simultaneously increasing child support paid to families, through gradual forgiveness of arrears conditional on payment of current child support obligations. The evaluation employs a randomized experimental design, nonexperimental analyses using propensity score matching and multilevel modeling techniques, and focus groups and follow‐up interviews. Results show a pattern of effects that suggests individuals responded to the program as intended. State‐ and family‐owed child support debt balances decreased for program participants, and participants paid more toward their child support obligations and arrears and made more frequent child support payments. The study findings suggest promise for the effectiveness of this program model in reducing child support debt burdens and in increasing families' receipt of child support, and they also point to ways in which the implementation of the program might be improved. © 2011 by the Association for Public Policy Analysis and Management.  相似文献
