Y a-t-il des politiques migratoires nationales ?

Depuis une vingtaine d’années, l’historiographie prête une attention de plus en plus fine au rôle des États dans le contrôle des migrations internationales, entendu dans ses aspects à la fois politiques et économiques. De la reconstitution du cadre légal des politiques publiques, à la sociographie de leur mise en œuvre quotidienne par les fonctionnaires en contact avec les migrants, émergent des aspects toujours plus nombreux de la « tyrannie du national ». On peut cependant, en croisant les ..

Trotsky e o Facebook: as “jornadas de junho”, o problema da estratégia e a disputa nas (novas e velhas) mídias │ Trotsky and Facebook: the "June journeys", the problem of strategy and the dispute in (old and new) media

RESUMO O objetivo deste artigo é reintroduzir o problema teórico da estratégia política emancipatória e do sujeito social no debate contemporâneo em torno dos novos movimentos sociais e de seus usos das novas tecnologias de informação e comunicação. Com o foco voltado para os grandes eventos que ocorreram nas ruas do Brasil em junho de 2013, o artigo discute a legislação brasileira e sul-americana de mídia e analisa a cobertura desses eventos pelos meios comerciais e alternativos, pela lente das teorias da luta cultural e da guerra de posição, de Gramsci. Palavras-chave: Estratégia; Mídia Comercial e Alternativa; Internet; “Jornadas de Junho”. ABSTRACT The aim of this paper is to re-introduce, in the contemporary debate about new social movements and their use of new information and communication technologies, the theoretical problem of political emancipatory strategy and of the social subject. Focusing on the big events that happened in the streets of Brazil in June 2013, the paper discusses Brazilian and South-American legislation on media and analyzes the coverage of these events by commercial and alternative media, through the lens of Gramsci's theories of cultural struggle and war of position.

Direitos das mulheres e a encontrabilidade da informação no portal da câmara dos deputados: perspectivas brasileiras rumo à Agenda 2030 das Nações Unidas

Objective. The article objective is to find out if the work developed by the information and documentation professionals, in the Information Architecture from the Chamber of Deputies’ portal, is allowing the Information Findability that helps to reach the objectives proclaimed in the Agenda 2030, regarding Women’s Rights.Method. The research is exploratory-evaluative with a bibliographic design and a qualitative approach.Results. Four research interfaces/sources were identified in the Information Architecture, from the Chamber of Deputies’ portal, with possibilities of finding similar information on the women’s rights, which are now complete, sometimes conflicting, requiring that the legislative data made available be confirmed, from the verification of proposals authorship, dates of filing, processing and filing or conversion into law.Conclusions. It is concluded that the analyzed portal does not have a fully effective Information Architecture, because it contains pervasive, repeated and misleading information in four different environments, and does not have an efficient classification, which is perfected in the finding of accurate and effective information. The information and documentation professionals of the portal should reevaluate taxonomy, as a classificatory structure for the organization of knowledge, regarding women´s interests and rights, taking into account the objectives described in the Agenda 2030, also considering the attributes of Information Competence and Information Ethics.Objetivo. El objetivo del artículo es conocer si el trabajo desarrollado por los profesionales de la información y la documentación, en la Arquitectura de la Información del portal de la Cámara de Diputados, está permitiendo la Encontrabilidad de la Información que ayude a alcanzar los objetivos proclamados en la Agenda 2030, respecto a los Derechos de las Mujeres.Método. La investigación es exploratoria-evaluativa con un diseño bibliográfico y un enfoque cualitativo.Resultados. Se identificaron cuatro interfaces/fuentes de investigación en la Arquitectura de la Información, del portal de la Cámara de Diputados, con posibilidades de encontrar información similar sobre los derechos de las mujeres, que en la actualidad son completas, a veces contradictorias, requiriendo que se confirmen los datos legislativos puestos a disposición, a partir de la verificación de la autoría de las propuestas, fechas de presentación, tramitación y archivo o conversión en ley.Conclusiones. Se concluye que el portal analizado no cuenta con una Arquitectura de la Información plenamente eficaz, ya que contiene información omnipresente, repetida y errónea en cuatro entornos diferentes, y no cuenta con una clasificación eficiente, que se perfeccione en la búsqueda de información precisa y eficaz. Los profesionales de la información y la documentación del portal deben reevaluar la taxonomía, como estructura clasificatoria para la organización del conocimiento, en relación con los intereses y derechos de las mujeres, teniendo en cuenta los objetivos descritos en la Agenda 2030, considerando también los atributos de la Competencia Informativa y la Ética de la Información.Objetivo. O objetivo do artigo é averiguar se o trabalho desenvolvido pelas/os profissionais da informação e documentação, na Arquitetura da Informação do portal da Câmara dos Deputados, está permitindo a Encontrabilidade da Informação que auxilie o alcance dos objetivos apregoados na Agenda 2030, no que tange aos Direitos das Mulheres.Método. A pesquisa é exploratório-avaliativa com delineamento bibliográfico e abordagem qualitativa.Resultados. Foram identificadas quatro interfaces/fontes de pesquisa na Arquitetura da Informação do portal da Câmara dos Deputados com possibilidades de encontrabilidade de informações semelhantes sobre os Direitos das Mulheres, que ora se completam, ora se apresentam conflituosas, exigindo que os dados legislativos disponibilizados sejam confirmados, a partir da verificação de autoria das proposições, datas de propositura, tramitação e arquivamento ou conversão em lei.Conclusões. Conclui-se que o portal analisado não possui uma Arquitetura da Informação plenamente eficaz, por conter informações pervasivas, repetidas e equivocadas em quatro ambientes diferentes, não possuindo classificação eficiente, que se perfaça na Encontrabilidade da Informação precisa e efetiva. As/os profissionais da informação e documentação do portal devem reavaliar a taxonomia, enquanto estrutura classificatória para organização do conhecimento, no que tange aos interesses e Direitos das Mulheres e em atenção aos objetivos descritos na Agenda 2030, considerando, ainda, os atributos da Competência em Informação e da Ética em Informação

Spacings of Quarkonium Levels with the Same Principal Quantum Number

The spacings between bound-state levels of the Schr\"odinger equation with the same principal quantum number $N$ but orbital angular momenta $\ell$ differing by unity are found to be nearly equal for a wide range of power potentials $V = \lambda r^\nu$, with $E_{N \ell} \approx F(\nu, N) - G(\nu,N) \ell$. Semiclassical approximations are in accord with this behavior. The result is applied to estimates of masses for quarkonium levels which have not yet been observed, including the 2P $c \bar c$ states and the 1D $b \bar b$ states.Comment: 20 pages, latex, 3 uuencoded figures submitted separately (process using psfig.sty

SEIS: Insight's Seismic Experiment for Internal Structure of Mars.

By the end of 2018, 42 years after the landing of the two Viking seismometers on Mars, InSight will deploy onto Mars' surface the SEIS (Seismic Experiment for Internal Structure) instrument; a six-axes seismometer equipped with both a long-period three-axes Very Broad Band (VBB) instrument and a three-axes short-period (SP) instrument. These six sensors will cover a broad range of the seismic bandwidth, from 0.01 Hz to 50 Hz, with possible extension to longer periods. Data will be transmitted in the form of three continuous VBB components at 2 sample per second (sps), an estimation of the short period energy content from the SP at 1 sps and a continuous compound VBB/SP vertical axis at 10 sps. The continuous streams will be augmented by requested event data with sample rates from 20 to 100 sps. SEIS will improve upon the existing resolution of Viking's Mars seismic monitoring by a factor of ∼ 2500 at 1 Hz and ∼ 200 000 at 0.1 Hz. An additional major improvement is that, contrary to Viking, the seismometers will be deployed via a robotic arm directly onto Mars' surface and will be protected against temperature and wind by highly efficient thermal and wind shielding. Based on existing knowledge of Mars, it is reasonable to infer a moment magnitude detection threshold of M w ∼ 3 at 40 ∘ epicentral distance and a potential to detect several tens of quakes and about five impacts per year. In this paper, we first describe the science goals of the experiment and the rationale used to define its requirements. We then provide a detailed description of the hardware, from the sensors to the deployment system and associated performance, including transfer functions of the seismic sensors and temperature sensors. We conclude by describing the experiment ground segment, including data processing services, outreach and education networks and provide a description of the format to be used for future data distribution.Electronic supplementary materialThe online version of this article (10.1007/s11214-018-0574-6) contains supplementary material, which is available to authorized users

Rationalizing Systems Analysis for the Evaluation of Adaptation Strategies in Complex Human‐Water Systems

LFP and oscillations - what do they tell us?

This review surveys recent trends in the use of local field potentials—and their non-invasive counterparts—to address the principles of functional brain architectures. In particular, we treat oscillations as the (observable) signature of context-sensitive changes in synaptic efficacy that underlie coordinated dynamics and message-passing in the brain. This rich source of information is now being exploited by various procedures—like dynamic causal modelling—to test hypotheses about neuronal circuits in health and disease. Furthermore, the roles played by neuromodulatory mechanisms can be addressed directly through their effects on oscillatory phenomena. These neuromodulatory or gain control processes are central to many theories of normal brain function (e.g. attention) and the pathophysiology of several neuropsychiatric conditions (e.g. Parkinson's disease)

Humility, Self-Awareness, and Religious Ambivalence: Another Look at Beckett's ‘Humanistic Quietism’

This is the accepted manuscript. The final version is available from Edinburgh University Press at http://www.euppublishing.com/doi/abs/10.3366/jobs.2014.0104. This article provides a commentary on the opaque and often contradictory arguments of ‘Humanistic Quietism’, Samuel Beckett's 1934 review of Thomas MacGreevy's Poems. Using Beckett's complicated relationship to both his own Protestant upbringing and the Catholicism of MacGreevy as a starting point, the article proposes new ways of understanding Beckett's ambivalent comments about MacGreevy's interiority, prayer-like poetry, humility, and quietism. It draws on Beckett's comments on Rilke, André Gide, and Arnold Geulincx, as well as his familiarity with Dante, to unpack the review's dense allusions and make sense of Beckett's aesthetic allegiances. </jats:p
