Re-imagining the Borders of US Security after 9/11: Securitisation, Risk, and the Creation of the Department of Homeland Security

The articulation of international and transnational terrorism as a key issue in US security policy, as a result of the 9/11 attacks, has not only led to a policy rethink, it has also included a bureaucratic shift within the US, showing a re-thinking of the role of borders within US security policy. Drawing substantively on the 'securitisation' approach to security studies, the article analyses the discourse of US security in order to examine the founding of the Department of Homeland Security, noting that its mission provides a new way of conceptualising 'borders' for US national security. The securitisation of terrorism is, therefore, not only represented by marking terrorism as a security issue, it is also solidified in the organisation of security policy-making within the US state. As such, the impact of a 'war on terror' provides an important moment for analysing the re-articulation of what security is in the US, and, in theoretical terms, for reaffirming the importance of a relationship between the production of threat and the institutionalisation of threat response. © 2007 Taylor & Francis

Persistent topology for natural data analysis - A survey

Natural data offer a hard challenge to data analysis. One set of tools is being developed by several teams to face this difficult task: Persistent topology. After a brief introduction to this theory, some applications to the analysis and classification of cells, lesions, music pieces, gait, oil and gas reservoirs, cyclones, galaxies, bones, brain connections, languages, handwritten and gestured letters are shown

From music to mathematics and backwards: introducing algebra, topology and category theory into computational musicology

International audienceDespite a long historical relationship between mathematics and music, the interest of mathematicians is a recent phenomenon. In contrast to statistical methods and signal-based approaches currently employed in MIR (Music Information Research), the research project described in this paper stresses the necessity of introducing a structural multidisciplinary approach into computational musicology making use of advanced mathematics. It is based on the interplay between three main mathematical disciplines: algebra, topology and category theory. It therefore opens promising perspectives on important prevailing challenges, such as the automatic classification of musical styles or the solution of open mathematical conjectures, asking for new collaborations between mathematicians, computer scientists, musicologists, and composers. Music can in fact occupy a strategic place in the development of mathematics since music-theoretical constructions can be used to solve open mathematical problems. The SMIR project also differs from traditional applications of mathematics to music in aiming to build bridges between different musical genres, ranging from contemporary art music to popular music, including rock, pop, jazz and chanson. Beyond its academic ambition, the project carries an important societal dimension stressing the cultural component of 'mathemusical' research, that naturally resonates with the underlying philosophy of the “Imagine Maths”conference series. The article describes for a general public some of the most promising interdisciplinary research lines of this project

Reclaiming the political : emancipation and critique in security studies

The critical security studies literature has been marked by a shared commitment towards the politicization of security – that is, the analysis of its assumptions, implications and the practices through which it is (re)produced. In recent years, however, politicization has been accompanied by a tendency to conceive security as connected with a logic of exclusion, totalization and even violence. This has resulted in an imbalanced politicization that weakens critique. Seeking to tackle this situation, the present article engages with contributions that have advanced emancipatory versions of security. Starting with, but going beyond, the so-called Aberystwyth School of security studies, the argument reconsiders the meaning of security as emancipation by making the case for a systematic engagement with the notions of reality and power. This revised version of security as emancipation strengthens critique by addressing political dimensions that have been underplayed in the critical security literature

First demonstration of multi-vendor and multi-domain EON with S-BVT and control interoperability over Pan-European testbed

The operation of multi-domain and multi-vendor EONs can be achieved by interoperable Sliceable Bandwidth Variable Transponders, a GMPLS / BGP-LS-based control plane and a planning tool. This paper reports the first full demonstration and validation this end-to-end architecture

Security (studies) and the limits of critique: why we should think through struggle

This paper addresses the political and epistemological stakes of knowledge production in post-structuralist Critical Security Studies. It opens a research agenda in which struggles against dominant regimes of power/knowledge are entry-points for analysis. Despite attempts to gain distance from the word ‘security’, through interrogation of wider practices and schemes of knowledge in which security practices are embedded, post-structuralist CSS too quickly reads security logics as determinative of modern/liberal forms of power and rule. At play is an unacknowledged ontological investment in ‘security’, structured by disciplinary commitments and policy discourse putatively critiqued. Through previous ethnographic research, we highlight how struggles over dispossession and oppression call the very frame of security into question, exposing violences inadmissible within that frame. Through the lens of security, the violence of wider strategies of containing and normalizing politics are rendered invisible, or a neutral backdrop against which security practices take place. Building on recent debates on critical security methods, we set out an agenda where struggle provokes an alternative mode of onto political investment in critical examination of power and order

On regional security governance once again: how analysis of the Southern Caucasus can advance the concept

Already introduced to the academic and political debate some years ago, the concept of “security governance” still needs to be clarified. In particular, four main shortcomings need to be overcome to make the concept more useful for an assessment of current security dynamics: in the first place, attention has been devoted more to “governance” than to “security”, while failing to consider the role of the understandings and perceptions of the actors involved in the governance system. Second, the literature on the actors (governmental or not) involved is still fragmented. Third, the literature on security governance has too often been detached from reflections on regionalism, while it would be useful to further explore the relationship between cognitive definitions of regional and security dynamics. Fourth, the literature has predominantly focused on Europe and the transatlantic area, overlooking processes of “region-building” in security terms in other “unexpected” geographical spaces. After proposing avenues to overcome the current gaps in the literature, the Southern Caucasus is chosen as a case study to show the different instances of security governance emerging, thanks to definitions of the region in security terms that have involved regional and external actors, of a state and non-state nature
