    Comparing international coverage of 9/11 : towards an interdisciplinary explanation of the construction of news

    Get PDF
    This article presents an interdisciplinary model attempting to explain how news is constructed by relying on the contributions of different fields of study: News Sociology, Political Communications, International Communications, International Relations. It is a first step towards developing a holistic theoretical approach to what shapes the news, which bridges current micro to macro approaches. More precisely the model explains news variation across different media organization and countries by focusing on the different way the sense of newsworthiness of journalists is affected by three main variables: national interest, national journalistic culture, and editorial policy of each media organization. The model is developed on the basis of an investigation into what shaped the media coverage of 9/11 in eight elite newspapers across the US, France, Italy and Pakistan

    Tax avoidance as an anti-austerity issue: the progress of a protest issue through the public sphere

    Get PDF
    Theorists of left and right agree that periods of crisis are fertile times at which to precipitate change. However, protesters on the periphery of the public sphere must overcome barriers, or what Habermas called ‘sluice gates’, if their discourse is to be publicly and politically influential. This study of newspaper discourse and activity in parliament and the public sphere over a six year period takes tax justice campaigning in the UK as a case study, and in particular protest group UK Uncut’s attempt to mobilize opposition to austerity by advocating a crackdown on tax avoidance as an alternative to cuts. It finds that whilst UK Uncut successfully amplified existing arguments previously raised by experts, trade unions and the left-leaning press, austerity barely figured in debate about tax avoidance once it was picked up by other actors in the public sphere on the other side of the 'sluice gates'. The reasons for this were structural and discursive, related to the role and interests of receptive actors at the institutional centre of the public sphere, and their ability, along with the conservative press, to transform the moral framing of tax avoidance from the injustice of making the poor pay for the financial crisis through cuts, into the 'unfairness' of middle class earners paying higher taxes than wealthier individuals and corporations. The latter reifies the 'hardworking taxpayer', and implies a more instrumental and clientalistic relationship to the state, and an essentially neoliberal sense of fairness. Where neoliberal ideology was challenged, it was in social conservative terms – nationalist opposition to globalisation, framing multinational corporations as a threat to the domestic high street – rather than protesters’ social democratic challenge to market power and social injustice. This indicates how a progressive message from the periphery can be co-opted into the currently resurgent right-wing populism

    Detecting the direction of a signal on high-dimensional spheres: Non-null and Le Cam optimality results

    Full text link
    We consider one of the most important problems in directional statistics, namely the problem of testing the null hypothesis that the spike direction θ\theta of a Fisher-von Mises-Langevin distribution on the pp-dimensional unit hypersphere is equal to a given direction θ0\theta_0. After a reduction through invariance arguments, we derive local asymptotic normality (LAN) results in a general high-dimensional framework where the dimension pnp_n goes to infinity at an arbitrary rate with the sample size nn, and where the concentration κn\kappa_n behaves in a completely free way with nn, which offers a spectrum of problems ranging from arbitrarily easy to arbitrarily challenging ones. We identify various asymptotic regimes, depending on the convergence/divergence properties of (κn)(\kappa_n), that yield different contiguity rates and different limiting experiments. In each regime, we derive Le Cam optimal tests under specified κn\kappa_n and we compute, from the Le Cam third lemma, asymptotic powers of the classical Watson test under contiguous alternatives. We further establish LAN results with respect to both spike direction and concentration, which allows us to discuss optimality also under unspecified κn\kappa_n. To investigate the non-null behavior of the Watson test outside the parametric framework above, we derive its local asymptotic powers through martingale CLTs in the broader, semiparametric, model of rotationally symmetric distributions. A Monte Carlo study shows that the finite-sample behaviors of the various tests remarkably agree with our asymptotic results.Comment: 47 pages, 4 figure

    Substantiating a political public sphere in the Scottish press : a comparative analysis

    Get PDF
    This article uses content analysis to characterize the performance of the media in a national public sphere, by setting apart those qualities that typify internal press coverage of a political event. The article looks at the coverage of the 1999 devolved Scottish election from the day before the election until the day after. It uses a word count to measure the election material in Scottish newspapers the Herald, the Press and Journal and the Scotsman, and United Kingdom newspapers the Guardian, the Independent and The Times, and categorizes that material according to discourse type, day and page selection. The article finds a number of qualities that typify the Scottish sample in particular, and might be broadly indicative of a political public sphere in action. Firstly, and not unexpectedly, it finds that the Scottish newspapers carry significantly more election coverage. Just as tellingly, though, the article finds that the Scottish papers offer a greater proportion of advice and background information, in the form of opinion columns and feature articles. It also finds that the Scottish papers place a greater concentration of both informative and evaluative material in the period before the vote, consistent with their making a contribution to informed political action. Lastly, the article finds that the Scottish sample situates coverage nearer the front of the paper and places a greater proportion on recto pages. The article therefore argues that the Scottish papers display features that distinguish them from the UK papers, and are broadly consistent with their forming part of a deliberative public sphere, and suggests that these qualities might be explored as a means of judging future media performance

    Compton scattering on the nucleon at intermediate energies and polarizabilities in a microscopic model

    Get PDF
    A microscopic calculation of Compton scattering on the nucleon is presented which encompasses the lowest energies -- yielding nucleon polarizabilities -- and extends to energies of the order of 600 MeV. We have used the covariant "Dressed K-Matrix Model" obeying the symmetry properties which are appropriate in the different energy regimes. In particular, crossing symmetry, gauge invariance and unitarity are satisfied. The extent of violation of analyticity (causality) is used as an expansion parameter.Comment: 35 pages, 15 figures, using REVTeX. Modified version to be published in Phys. Rev.

    The Majorana experiment: an ultra-low background search for neutrinoless double-beta decay

    Full text link
    The observation of neutrinoless double-beta decay would resolve the Majorana nature of the neutrino and could provide information on the absolute scale of the neutrino mass. The initial phase of the Majorana experiment, known as the Demonstrator, will house 40 kg of Ge in an ultra-low background shielded environment at the 4850' level of the Sanford Underground Laboratory in Lead, SD. The objective of the Demonstrator is to determine whether a future 1-tonne experiment can achieve a background goal of one count per tonne-year in a narrow region of interest around the 76Ge neutrinoless double-beta decay peak.Comment: Presentation for the Rutherford Centennial Conference on Nuclear Physic

    Complete one-loop analysis of the nucleon's spin polarizabilities

    Get PDF
    We present a complete one-loop analysis of the four nucleon spin polarizabilities in the framework of heavy baryon chiral perturbation theory. The first non-vanishing contributions to the isovector and first corrections to the isoscalar spin polarizabilities are calculated. No unknown parameters enter these predictions. We compare our results to various dispersive analyses. We also discuss the convergence of the chiral expansion and the role of the delta isobar.Comment: 4 pp, REVTE
