The Italian payback effect: the causal impact of the great recession on political discontent
No full textGrounding on the theories of economic voting and political opposition, this paper investigates whether the Italian Local Labour Markets (LLMs) most affected by the Great Recession reacted in the ballot box voting against the domestic institutions or in favour of anti-European parties. We exploit a recent econometric technique in the counterfactual framework, which adopts a non-parametric generalisation of the difference-in-differences estimator. Our findings show a causal negative impact on the share of Berlusconi's party, the incumbent party during the crisis, statistically significant in those LLMs with the lowest institutional quality and in the Centre and in the Islands of Italy. We find no causal effect on the anti-European vote whatsoever. People living in the LLMs that suffered the most the effects of the Great Recession used their vote to harm the party in charge, which they deemed responsible for the economic consequences, with a payback effect
Multiple-energy x-ray holography: Polarization effect
No full textWe present the theory for multiple-energy x-ray holography (MEXH), using a multipole expansion for the scattered field. We find that light polarization plays a crucial role in the reconstruction of the image, and we suggest how to use it in order to eliminate aberration effects. The method we propose is alternative to the scattered-wave-included Fourier transform method, but has the advantage that no theoretical calculations are required to redefine the hologram
Atomic holography: does a polarized light beam improve the image?
No full textPerforming three measurements (holograms) on the same sample with the same beam but different polarization, spurious spots can be reduced and the holographic image appears to be better. The change of polarization requires nothing more than a rotation of the sample around the beam's direction. For the reconstruction of the image one applies the standard Fourier transform (FT) techniques on a combination of the holograms obtained. The resulting image is better than that obtained with an unpolarized beam
Multiphonon Effects in Atom Surface Scattering: the Case of Pt(111)
No full textIn this paper we show that the huge structures recently observed experimentally ith the He-surface atom scattering technique by using hot beams can be related with some confidence to multiphonon scattering events
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Calculation of Debye-Waller factor for atom-surface scattering:He on Ag(111)
No full textBy a consistent application of the distorted-wave Born approximation, the Debye-Waller exponent for the scattering of He atoms from the Ag(111) surface is directly computed. When diffraction is negligible, as in this case, the decrease in specular intensity is simply obtained by summing the scattering due to all possible one-phonon processes. Using one-phonon computed intensities that agree with experiment along high-symmetry directions of the surface Brillouin zone, we find that the computed Debye-Waller exponent agrees with experiment and corresponds to an effective Debye temperature of 241 K. All corrections to the eikonal-type formula, 2W=4pz2〈uz2〉, are automatically included. In particular, the contribution of phonons with high parallel momentum is sharply cut off
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
