    The purpose of this article is to explore the ways in which the EU’s counter-terrorism discourse, the 'fight against terrorism', is constructed, and the ways in which it functions both rhetorically and in practice. It argues that that 'EU identity' is constituted through and is central to the constitution of EU counter-terrorism policy. The approach taken is constructivist in nature drawing on a discourse analysis of primarily European Council policy documents, as well as the reports and speeches of the EU Counter-Terrorism Co-ordinator. In particular, it identifies three strands of the discourse that it is argued play a key role in the construction of a terrorist 'other'. These three strands include: terrorism as crime and as an emotive act of violence; terrorism as an act perpetrated solely by non-state actors; and terrorism as a 'new' and 'evolving' threat. The article proceeds in three steps. First, it outlines the theoretical considerations that underpin this research, including its empirical application. Second, it demonstrates how each strand of the discourse is constructed. Third, it discusses the functioning of the discourse, including the contested nature of the 'terrorism knowledge' that underpins the EU's counter-terrorism approach. The article concludes by reflecting on what this case study contributes to our understanding of EU counter-terrorism policy, as well as explaining how the notion of the terrorist 'other' could provide the basis for a future research agenda that deepens our understanding of how the identity of the EU is constituted

    Acousto-Ultrasonic Monitoring of Glueline Curing

    Get PDF
    Hard maple electrodes were bonded with three types of epoxies in a lap joint and acousto-ultrasonic transmission monitored during curing. The electrodes, 3.2 x 25 x 115 mm, were lapped for a 25- x 25-mm bond area. Standard acoustic emission sensors, 175 kHz transmitter and 75 kHz receiver, were used to provide an RMS voltage output, which increased as the adhesive cured. The transmission increase was quantified using a halftime to cure. The increase in transmission is comparable to the predicted increase in longitudinal modulus. Increasing glueline thickness from 0.05 to 0.5 mm caused an increase in apparent cure time as measured by the halftime. By controlling glueline temperature, an activation energy was determined from the halftime to cure

    Modalités spatio-temporelles de la dispersion d'alevins de saumon atlantique (Salmo salar L.) à l'émergence

    Nous avons Ă©tudiĂ© la dispersion (vitesse, durĂ©e, distance) d'alevins de saumon atlantique Ă  l'Ă©mergence dans un ruisseau expĂ©rimental.Le rythme journalier de dĂ©valaison suit Ă©troitement le rythme d'Ă©mergence des alevins, ce qui montre une bonne corrĂ©lation entre les deux activitĂ©s, tout au moins en dĂ©but de pĂ©riode. Les histogrammes de capture des alevins Ă©chantillonnĂ©s tous les 10 m prĂ©sentent des caractĂ©ristiques de forme similaires (durĂ©e, asymĂ©trie et aplatissement). Jusqu'au pic des captures, prĂšs de 50 % des alevins dĂ©valent en 5 jours. Ils se dispersent Ă  partir de la frayĂšre sur 50 m en 3 ou 4 nuits et forment une cohorte homogĂšne d'aprĂšs leur rythme de dĂ©valaison et leur taille. AprĂšs le mode, les captures sont plus Ă©talĂ©es dans le temps (environ 10 jours) et montrent plus de variabilitĂ© en fonction de la distance. Les alevins rĂ©sidents ne sont pas distribuĂ©s uniformĂ©ment dans les cinq biefs : les densitĂ©s, de mĂȘme que les poids moyens, tendent Ă  augmenter vers l'aval. Plus de 50 % de la population d'alevins survivants s'est Ă©tabli dans les 50 m en aval de la frayĂšre. Les rĂ©sultats rĂ©vĂšlent deux vagues de dĂ©valants. La premiĂšre vague de dispersion, aussitĂŽt aprĂšs l'Ă©mergence, est rapide et importante. Elle ne dĂ©pendrait pas directement de la compĂ©tition territoriale et de la densitĂ©, mais permettrait d'Ă©viter des densitĂ©s localement trop Ă©levĂ©es et d'utiliser plus efficacement les zones productives situĂ©es en aval de la frayĂšre. La deuxiĂšme vague d'alevins dĂ©valants correspondrait aux Ă©mergents tardifs et aux poissons soumis aux effets de la compĂ©tition territoriale.We have analysed the dispersal patterns (rate, duration, extent) of Atlantic salmon fry at emergence. The rate and duration of movement, and the distance travelled were measured in an experimental stream, located near S-PĂ©e-sur-Nivelle, in SW France. A batch of 8 850 eyed eggs, from the grilse wild stock of the Nivelle River, was buried in the gravel substrate at the upstream end of a series of 5 sections, each 10 m long by 3 m wide. Shortly before emergence, drift nets equipped with fry traps were installed at the downstream end of each section. The nets sampled about 1/10 of the flow, except for those nets at the downstream end of the last section which collected all downstream moving fry. The traps were visited every morning and the fry enumerated. At the time of peak movements, samples were collected for length-weight measurements. At the end of the dispersal period, fry which had settled in the different sections (residents) were captured with electro-fishing gear and measured.The pattern of downstream movement of fry in a set of drift nets was closely related to the pattern of emergence from an artificial redd upstream of the nets. Hence, emergence and downstream dispersion were well synchronized, at least during the first part of the dispersal from the redd. The time-frequency histograms of fry sampled every 10 m showed the same pattern and general shape (duration, skewness and kurtosis). Until the peak of captures, nearly 50 % of all downstream moving fry were caught within 5 days in each section. Dispersion from the redd over 50 m occurred within 3-4 nights. During this first period, the fry exhibited similar characteristics with respect to activity patterns and sizes. After the modal day of capture, catches were more evenly spread over time (about 10 days) and showed greater variability in relation to the distance travelled from the redd.Resident fry were not uniformly distributed in the 5 sections : densities, as well as average weights, increased from upstream to downstream. Over 50 % of the surviving fry (75.3 % of planted eggs) settled within 50 m downstream from the redd.Our results showed two waves of downstream dispersion. The first dispersal wave, occurring soon after emergence, was swift and implied large numbers of fry. It was not the result of territorial competition or density, since it occurred before the onset of aggressive behaviour. Rather, this first wave appeared as process to avoid the formation of clumps and allow for a more efficient use of the more productive zones, generally located downstream from the redd. The second wave of downstream moving fry corresponded to late emerging fry and to those fry which, 10-12 days after emergence, were displaced by territorial competition

    Exhaled nitric oxide in ethnically diverse highĂą altitude native populations: A comparative study

    ObjectivesAndean and Tibetan highĂą altitude natives exhibit a high concentration of nitric oxide (NO) in the lungs, suggesting that NO plays an adaptive role in offsetting hypobaric hypoxia. We examined the exhaled NO concentration as well as partial pressure of several additional highĂą altitude native populations in order to examine the possibility that this putative adaptive trait, that is, high exhaled NO, is universal.MethodsWe recruited two geographically diverse highland native populations, Tawang Monpa (TM), a Tibetan derived population in NorthĂą Eastern India (n = 95, sampled at an altitude of ~3,200Ăą m), and Peruvian Quechua from the highland Andes (n = 412). The latter included three distinct subgroups defined as those residing at altitude (QĂą HAR, n = 110, sampled at 4,338Ăą m), those born and residing at seaĂą level (QĂą BSL, n = 152), and those born at altitude but migrant to seaĂą level (QĂą M, n = 150). In addition, we recruited a referent sample of lowland natives of European ancestry from Syracuse, New York. Fraction of exhaled NO concentrations were measured using a NIOX NIMO following the protocol of the manufacturer.ResultsPartial pressure of exhaled nitric oxide (PENO) was significantly lower (pĂą <Ăą .05) in both highĂą altitude resident groups (TM = 6.2Ăą 屝 0.5 nmHg and QĂą HAR = 5.8Ăą 屝 0.5 nmHg), as compared to the groups measured at sea level (USA = 14.6Ăą 屝 0.7 nmHg, QĂą BSL = 18.9Ăą 屝 1.6 nmHg, and QĂą M = 19.2Ăą 屝 1.7 nmHg). PENO was not significantly different between TM and QĂą HAR (pĂą <Ăą .05).ConclusionIn contrast to previous work, we found lower PENO in populations at altitude (compared to seaĂą level) and no difference in PENO between Tibetan and Andean highland native populations. These results do not support the hypothesis that high nitric oxide in human lungs is a universal adaptive mechanism of highland native populations to offset hypobaric hypoxia.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/151909/1/ajpa23915.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/151909/2/ajpa23915_am.pd
