ISIS and the climate of fear -- a political-psychology perspective

2014年6月のイスラーム国（以下ISIS）のメディアへの華々しい登場以降、米国政治を規定する主要な要因の1つとして「恐怖心」がかつてない程の重要性を帯びてきている。本稿では政治心理学的な分析手法を援用しつつ、ISISが何よりも「テロ攻撃集団」としていかに「恐怖心」を醸成するための洗練された戦略を実践しているか、またそれが統計的には圧倒的に中東現地のムスリム一般住民を標的にしており、本来的にS.ハンティントン的な「西欧文明に敵対するイスラーム」という問題を内包していないにもかかわらず、米国エスタブリッシュメントによる他者への「恐怖心」によって如何に本質が曲解されて「ムスリム排斥」のような情緒的な政治主張に向かわせているかの契機を分析する。筆者は論稿中でマキャベリから以降最近に至るまでの政治学関係の議論を渉猟しつつ、「恐怖心」をめぐる問題が「テロル」との関係においていかに扱われてきたかを再検討し、西欧のメディアにおける「テロ集団」としてのISISの登場が政治学的な観点から提起している問題の新しさと古さを跡付けようとする。同時に現在の米国社会を覆っているイスラモフォビアの情緒的反応についてもその淵源が古くかつ政治的に根深い問題から発していることを指摘している。本論稿の分析は直接的にはISISによって政治的な雰囲気が大きく変容するなかで大統領選挙の年を迎えている米国の国内政治を扱うものであるが、ここでの議論は「アラブの春」以降のシリア危機に発する難民問題に直面している欧州（EU）や、2015年11月のパリのテロ多発事件以降緊迫した雰囲気に覆われているフランスの政治状況にも通底しており、その意味では偶々2014年にISIS によって惹起されたとはいえそれ自体が自律的な展開の契機を内包する現代社会の政治的な抑圧的システムのグローバルな拡大と拡散に警鐘を鳴らそうとするものである。

Preliminary approach to neutron instrument selecction at ESSB-Bilbao based on experience at ISIS molecular spectroscopy group

Collaborative efforts between the Neutronics and Target Design Group at the Instituto de Fusión Nuclear and the Molecular Spectroscopy Group at the ISIS Pulsed Neutron and Muon Source date back to 2012 in the context of the ESS-Bilbao project. The rationale for these joint activities was twofold, namely: to assess the realm of applicability of the low-energy neutron source proposed by ESS-Bilbao - for details; and to explore instrument capabilities for pulsed-neutron techniques in the range 0.05-3 ms, a time range where ESS-Bilbao and ISIS could offer a significant degree of synergy and complementarity. As part of this collaboration, J.P. de Vicente has spent a three-month period within the ISIS Molecular Spectroscopy Group, to gain hands-on experience on the practical aspects of neutron-instrument design and the requisite neutron-transport simulations. To date, these activities have resulted in a joint MEng thesis as well as a number of publications and contributions to national and international conferences. Building upon these previous works, the primary aim of this report is to provide a self-contained discussion of general criteria for instrument selection at ESS-Bilbao, the first accelerator-driven, low-energy neutron source designed in Spain. To this end, Chapter 1 provides a brief overview of the current design parameters of the accelerator and target station. Neutron moderation is covered in Chapter 2, where we take a closer look at two possible target-moderator-reflector configurations and pay special attention to the spectral and temporal characteristics of the resulting neutron pulses. This discussion provides a necessary starting point to assess the operation of ESSB in short- and long-pulse modes. These considerations are further explored in Chapter 3, dealing with the primary characteristics of ESS-Bilbao as a short- or long-pulse facility in terms of accessible dynamic range and spectral resolution. Other practical aspects including background suppression and the use of fast choppers are also discussed. The guiding principles introduced in the first three chapters are put to use in Chapter 4 where we analyse in some detail the capabilities of a small-angle scattering instrument, as well as how specific scientific requirements can be mapped onto the optimal use of ESS-Bilbao for condensed-matter research. Part 2 of the report contains additional supporting documentation, including a description of the ESSB McStas component, a detailed characterisation of moderator response and neutron pulses, and estimates ofparameters associated with the design and operation of neutron choppers. In closing this brief foreword, we wish to thank both ESS-Bilbao and ISIS for their continuing encouragement and support along the way.

Revealing the Face of Isis

This reply to Gash’s (Found Sci 2014) commentary on Nescolarde-Selva and Usó-Doménech (Found Sci 2014b) answers the questions raised and at the same time opens up new questions.

The Goodness of Simultaneous Fits in ISIS

In a previous work, we introduced a tool for analyzing multiple datasets simultaneously, which has been implemented into ISIS. This tool was used to fit many spectra of X-ray binaries. However, the large number of degrees of freedom and individual datasets raise an issue about a good measure for a simultaneous fit quality. We present three ways to check the goodness of these fits: we investigate the goodness of each fit in all datasets, we define a combined goodness exploiting the logical structure of a simultaneous fit, and we stack the fit residuals of all datasets to detect weak features. These tools are applied to all RXTE-spectra from GRO 1008−57, revealing calibration features that are not detected significantly in any single spectrum. Stacking the residuals from the best-fit model for the Vela X-1 and XTE J1859+083 data evidences fluorescent emission lines that would have gone undetected otherwise.
