Al Qaeda has crafted a successful media strategy that is adeptly suited for the war of ideas against the United States. Osama bin Laden and Ayman al-Zawahiri have demonstrated a great ability to lead plural groups and exploit innovation with the use of technology. This article explores how they have connected with diverse audiences around the world with a constant message. The repetition of their platform themes and use of “message projection opportunities” demonstrate a great understanding of human nature, marketing strategy, global media, and world politics. In line with Prospect Theory, bin Laden and Zawahiri's messaging strategy emphasizes stemming losses over solidifying gains. Only through a better understanding of Al Qaeda's media strategy and all of its strengths, weaknesses, and idiosyncrasies can the United States truly recognize what it is up against and begin to construct an effective and comprehensive counter strategy. 相似文献

Most methodological work on project appraisal in developing countries have so far been primarily concerned with industrial projects and distortions in the foreign trade sector.1 In this paper interest is focused on projects in the rural sector and in particular on a neglected aspect of labour cost valuation, viz. valuation of individuals’ work effort expended. 相似文献

Although foreign fighting is hardly new, scholarly research on the phenomenon is only a decade old. Since 2005, there has also been a dramatic rise in the number of transnational insurgents fighting in the Middle East, and they appear to have become the face of the jihad movement. However, of the dozens of foreign fighter contingents around the world in recent decades, only about half have been Islamists. In this article, I contend that the difference between the other contemporary and historical foreign fighter groups and the jihadis is not one of mobilization or effectiveness, but of persistence. Most other foreign fighters demobilized at the end of their conflicts and reintegrated. I argue that the primary factor that accounts for the persistence of the jihadis was the policies of their home and host states that prevented reintegration and created cohorts of stateless, and now professionalized, actors who perpetuate in weakly-governed conflict zones. In presenting this argument, I first attempt to establish a common working definition of foreign fighter based on the first decade of discourse in this emerging field of study, and present a comparative examination of the largest recorded foreign fighter mobilizations. 相似文献

Gerasimov's plastic facial reconstruction method is notoriously difficult to repeat from the published literature. Primarily, this is because of the method's underlying qualitative basis but other factors contribute including: misreports in the secondary literature of Gerasimov's method essence; a lack of published details concerning Gerasimov's modeling mastic; Gerasimov's deviation from his own published nose projection prediction guidelines; and continued refinement of the methods in the 15 years following their foremost publication. As Gerasimov cannot be consulted to resolve these issues, we provide solutions via one of his five former principal students. This includes clarification of Gerasimov's method and use of soft tissue depths; the constitution of his modeling mastic; methods used for nose projection prediction; and refinements made to his methods following their primary publication. 相似文献

Fiscal, administrative, and political tensions among the partners in the federal system have not eased, and perhaps have grown, since the demise of the U.S. Advisory Commission on Intergovernmental Relations in 1996. Yet no governmental organizational capacity exists to address big intergovernmental questions in an ongoing manner through nonpartisan or bipartisan research, data collection, deliberation, and policy formulation. 相似文献

By pooling independent study means (), the T‐Tables use the central limit theorem and law of large numbers to average out study‐specific sampling bias and instrument errors and, in turn, triangulate upon human population means (μ). Since their first publication in 2008, new data from >2660 adults have been collected (c.30% of the original sample) making a review of the T‐Table's robustness timely. Updated grand means show that the new data have negligible impact on the previously published statistics: maximum change = 1.7 mm at gonion; and ≤1 mm at 93% of all landmarks measured. This confirms the utility of the 2008 T‐Table as a proxy to soft tissue depth population means and, together with updated sample sizes (8851 individuals at pogonion), earmarks the 2013 T‐Table as the premier mean facial soft tissue depth standard for craniofacial identification casework. The utility of the T‐Table, in comparison with shorths and 75‐shormaxes, is also discussed. 相似文献

Cold case squads have garnered much attention; however, they have yet to undergo significant empirical scrutiny. In the present study, the authors interviewed investigators and reviewed 189 solved and unsolved cold cases in Washington, D.C., to determine whether there are factors that can predict cold case solvability. In the interviews, new information from witnesses or information from new witnesses was cited as the most prevalent reason for case clearance. The case reviews determined that there were factors in each of the following domains that predicted whether cases would be solved during cold case investigations: Crime Context, Initial Investigation Results, Basis for Opening Cold Case, and Cold Case Investigator Actions. The results suggest that it is possible to prioritize cold case work based on the likelihood of investigations leading to clearances. 相似文献
