An analysis of Islamic State’s Dabiq magazine

This article analyses Dabiq magazine to explore the strategic logic of Islamic State (IS) appeals to English-speaking Muslims. It offers the field a conceptual framework through which to analyse IS’s communications strategy and a top-down empirical study of Dabiq’s contents. This paper argues that Dabiq appeals to its audiences by strategically designing in-group identity, Other, solution and crisis constructs which it leverages via value-, crisis- and dichotomy-reinforcing narratives. By fusing identity- and rational-choice appeals, IS provides its audiences with a powerful ‘competitive system of meaning’ that is designed to shape its readership’s perceptions, polarise their support and drive their radicalisation.     

Embedding the War on Terror: State and Civil Society Relations

The global war on terror was used by the Bush administration and its allies to defend a US dominated geopolitical configuration. To this end, counter‐terrorism measures (CTMs) were introduced which strengthened the alignment of development aid with diplomacy and defence. The broad, adverse effects of CTMs on civil liberties and human rights are well documented. Despite the advent of a new US administration and a ‘soft power’ approach to international relations, the legacy of the war on terror remains embedded in the laws, policies and attitudes of many states and regimes that continue to enclose the lives of citizens. This article describes the experiences of civil society organizations (CSOs) as ‘securitization’ processes unfolded. Studies over two years involving some forty countries provide an on‐the‐ground view to probe the gains and losses of securitization, both for governments in the US‐led ‘coalition of the willing’ and for civil society in terms of the pressures emerging from a development‐for‐security agenda. The authors identify some of the perverse zero‐sum effects on governments of CTM philosophy and the means employed. Findings also show asymmetry between northern and southern CSOs in terms of their negative‐sum subordination, found in the definition of security and in the vulnerability to new risks involved in undertaking development work.     

Adaptive Cell Tower Location Using Geostatistics. 基于地统计学的适应性基站发射塔选址研究

In this article, we address the problem of allocating an additional cell tower (or a set of towers) to an existing cellular network, maximizing the call completion probability. Our approach is derived from the adaptive spatial sampling problem using kriging, capitalizing on spatial correlation between cell phone signal strength data points and accounting for terrain morphology. Cell phone demand is reflected by population counts in the form of weights. The objective function, which is the weighted call completion probability, is highly nonlinear and complex (nondifferentiable and discontinuous). Sequential and simultaneous discrete optimization techniques are presented, and heuristics such as simulated annealing and Nelder–Mead are suggested to solve our problem. The adaptive spatial sampling problem is defined and related to the additional facility location problem. The approach is illustrated using data on cell phone call completion probability in a rural region of Erie County in western New York, and accounts for terrain variation using a line‐of‐sight approach. Finally, the computational results of sequential and simultaneous approaches are compared. Our model is also applicable to other facility location problems that aim to minimize the uncertainty associated with a customer visiting a new facility that has been added to an existing set of facilities.
