Terrorism as Ritual Process and Cultural Trauma: a Performative Analysis of ISIS\u2019s Attacks in Europe

Sociological reflection on Islamist terrorism focussed itself almost exclusively on the religious aspect of radicalisation of Islam, spending little efforts to widen the analytic perspective to the effects of ISIS actions on the (re)definition of the identity and the collective memory of the targeted nation. This article will offer a different point of view, providing a cultural sociological reading of Paris Attacks, aimed at understanding its performative aspects. We will approach Paris Attacks as an example of social drama (Turner, 1982) and will focus on the ritual efforts spent by France to manage, repair and define the cultural trauma (Alexander et al., 2004) deriving from the attacks. Data will consist of a performative analysis of ISIS\u2019s strategy in Europe and of the counter-terrorist demonstration held in Paris on the 9th of January 2015; and of a frame analysis of the speech pronounced by Francois Hollande on November 16th 2015, after the Paris attacks, and of all the articles published on the main French newspapers during the first week after the events. In the conclusions, we will discuss how those events help to conceive a new kind of cultural trauma that is typical of the age of weak events and of distrust in public institutions

Jihad online : how do terrorists use the internet?

Terrorism is designed to attract attention to the terrorist's cause and to spread fear and anxiety among wide circles of the targeted population. This paper provides information about the ways terrorists are using the Internet. The threat of terrorism is real and significant. As the Internet becomes a major arena for modern terrorists, we need to understand how modern terrorism operates and devise appropriate methods to forestall such activities

Measuring stellar magnetic fields with the low resolution spectropolarimeter of the William Herschel Telescope

Despite the influence of magnetic fields on the structure and evolution of stars is largely demonstrated from the theoretical point of view, their observational evidence in non-degenerated stars is still rather scanty and mainly circumscribed to bright objects (V<10). Stellar magnetic fields are commonly measured on the basis of circular spectropolarimetry at high/middle resolution across the profile of metal lines. The present sensitivity of telescopes and spectrographs makes this still an almost prohibitive method for faint stars. In principle, stellar magnetic fields can be also measured on the basis of low resolution spectropolarimetry, with very important results obtained at the 8 m ESO telescopes with FORS1. The trade off between S/N and spectral resolution in measuring stellar magnetic fields justify an attempt, here presented, to perform these measurements at the 4.5 m William Herschel Telescope. HD3360, one of the stars with the weakest known magnetic field, and the magnetic chemically peculiar stars HD10783, HD74521 and HD201601 have been observed with the spectropolarimeter ISIS in the 3785-4480 A range. Measured stellar magnetic fields, from Stokes I and V spectra with S/N > 600, show an internal error of <50 G selecting the whole interval and <200 G within a Balmer line. Ripples in the Stokes V spectra of HD3360 result in an instrumental positive magnetic field certainly not larger than 80 G.Comment: 7 pages, 4 figures, MNRAS in pres

Variable stars in the dwarf irregular galaxy NGC 6822: the photometric catalogue

Deep B,V time-series photometry obtained with the ESO Very Large Telescope has been used to identify variable stars in the dwarf irregular galaxy NGC 6822. We surveyed a 6.8x6.8 arcmin area of the galaxy and detected a total number of 390 candidate variables with the optimal image subtraction technique (Alard 2000). Light curves on a magnitude scale were obtained for 262 of these variables. Differential flux light curves are available for the remaining sample. In this paper we present the photometric catalogue of calibrated light curves and time-series data, along with coordinates and classification of the candidate variables. A detailed description is provided of the procedures used to identify the variable stars and calibrate their differential flux light curves on a magnitude scale.Comment: 22 pages, 19 figures only as JPEG.

Balancing Autonomy Rights and Protection:Children’s Involvement in a Child Safety Online Project

Researchers who involve children in their research are faced with the challenge of choosing between differing theoretical approaches which can prioritise children’s autonomy rights or their ‘vulnerability’ and their need to be protected. Somewhat confusingly, ethical guidelines seem to reflect a combination of these approaches. Even when researchers have settled on their preferred approach, they may find that this then has to be modified in accordance with gatekeeper requirements. In the context of children’s involvement in a child safety online project, this paper highlights the difficulties encountered because of a tension between children’s autonomy rights, educational norms in a school setting and child protection concerns, and considers whether an appropriate balance was achieved
