Diffusion of scientific credits and the ranking of scientists

Recently, the abundance of digital data enabled the implementation of graph based ranking algorithms that provide system level analysis for ranking publications and authors. Here we take advantage of the entire Physical Review publication archive (1893-2006) to construct authors' networks where weighted edges, as measured from opportunely normalized citation counts, define a proxy for the mechanism of scientific credit transfer. On this network we define a ranking method based on a diffusion algorithm that mimics the spreading of scientific credits on the network. We compare the results obtained with our algorithm with those obtained by local measures such as the citation count and provide a statistical analysis of the assignment of major career awards in the area of Physics. A web site where the algorithm is made available to perform customized rank analysis can be found at the address http://www.physauthorsrank.orgComment: Revised version. 11 pages, 10 figures, 1 table. The portal to compute the rankings of scientists is at http://www.physauthorsrank.or

Court of Milan holds video sharing platforms liable for copyright infringement

On January 2011 and May 2011 the Court of Milan released two interesting decisions in Reti Televisive Italiane S.p.A. v Italia On Line S.r.l. (published on 7 June 2011) and Reti Televisive Italiane S.p.A. v Yahoo! Italia S.r.l. and Yahoo! Inc. (published on 9 September 2011). The Court found that the Internet Service Providers Italia On Line and Yahoo! Italia are liable for copyright infringement in connection with the uploading of several videos on their platforms and cannot rely on the hosting provider exemption under the E-Commerce Directive. The two decisions are particularly interesting as the Court of Milan “created” from scratch a new category of Internet Service Provider liability, i.e. the so-called “active hosting” liability

‘Communication to the Public’ in FAPL v QC Leisure and Murphy v Media Protection Services (Joined Cases C-403/08 and C-429/08)

On 4 October 2011 the Court of Justice of the European Union released its decision in FAPL v QC Leisure and Murphy v Media Protection Services (Joined Cases C-403/08 and C-429/08). Amongst the many aspects dealt with, the Court gave its interpretation of ‘communication to the public’ under Article 3(1) of the Info Society Directive and concluded that the showing of live Premier League matches in pubs does amount to such communication

Los humos del mercedario: el postre americano de 'La villana de Vallecas'

El estudio de cómo se representan en las obras áureas algunos objetos de la vida cotidiana, como el tabaco, avanza la comprensión de las mismas, como es el caso de 'La villana de Vallecas', de Tirso de Molina. Utilizando la dicha comedia y fuentes tratadísticas de la época, este artículo muestra que el tabaco –como el chocolate– fue objeto de la fascinación del mercedario, que vio en él un ambiguo símbolo del Nuevo Mundo, del consumismo avant la lettre y de la sensualidad. The study of how some everyday objects, such as tobacco, are represented in Golden Age works contributes to our understanding of these works, as is the case with Tirso de Molina’s 'La villana de Vallecas'. Utilizing sources including this comedy and contemporary treatises, this article shows that tobacco –like chocolate– was an object of fascination for the Mercedarian, who saw in it an ambiguous symbol of the New World, of consumerism avant la lettre, and of sensuality

Who gets what? The interactive effect of MPs’ sex in committee assignments in Portugal

This article investigates the role of key individual-level factors, namely expertise, seniority and preferences in women’s assignments to legislative committees. It focuses on Portugal and draws on biographical data on MPs in five elections until 2009 and interviews with 20 legislators in 2014. The results show that female and male MPs have a similar probability of being appointed to powerful and economic issue committees, but female MPs are more likely to be appointed to social issue committees regardless of expertise and seniority. Although this outcome might be the product of their own preferences, it is influenced by embedded gender norms.info:eu-repo/semantics/publishedVersio

20 years of network community detection

A fundamental technical challenge in the analysis of network data is the automated discovery of communities - groups of nodes that are strongly connected or that share similar features or roles. In this commentary we review progress in the field over the last 20 years.Comment: 6 pages, 1 figure. Published in Nature Physic

Export performance : the case of the exports of cork stoppers from Portugal to emergent economies

Export performance has always been a non-consensual topic in the field of International Business, despite being one of the most researched areas. This dissertation starts aiming at understanding the influence of internal factors to the firm, export market characteristics and export marketing strategy in the export venture of a firm. After presenting a literature review, it was explained the research questions, and a conceptual framework was presented. This dissertation’s methodology has been that of a case study, where exports of cork stoppers from Portugal to emergent economies were studied. The results support the contention that commitment with export activity, contribution of firm’s resources to the success of the venture, international business knowledge, export market characteristics, and export venture marketing strategy adaptation (influenced by the factors previously mentioned) are key factors to a successful export venture performance. Then theoretical and managerial findings are discussed and directions for further research are given

Current blockage in sheared flow: Experiments and numerical modelling of regular waves and strongly sheared current through a space-frame structure

Space-frame structures supporting marine renewable energy devices such as offshore wind turbines are exposed to complex hydrodynamic forces resulting from the coexistence of waves and currents. Previous investigations on the interaction of such structure acting as an obstacle array with regular waves and in-line uniform current reported a reduced fluid loading due to current blockage. This paper documents laboratory-scale experimental evidence for reduced fluid loading on a truss structure exposed to regular waves with in-line sheared current in shallow water. Strongly sheared current of different speeds is generated and profiled using purposely-built wire resistance arrays in a wave-current flume, and a range of regular waves are created using a piston-type wavemaker. The global hydrodynamic force time history on a truss structure is measured for a range of sheared current speeds and regular wave heights. For all test cases, two loading configurations are considered, with the truss positioned end-on and diagonal to the incident flow direction. Comparisons are made with the analytical current blockage model for steady uniform current by Taylor (1991) and Taylor et al. (2013), and with the numerical simulations conducted in OpenFOAM using a porous tower model following the approach by Santo et al. (2015). Under the same input condition, the diagonal loading configuration is observed to attract higher forces and therefore it should not be ignored when assessing the survivability of such structures. Overall, good agreement in terms of the peak forces and the shapes of force time history is achieved, all with a single and consistent value for each of Cd and Cm. On the other hand, predictions using standard Morison with no blockage and the present API recommendation with the same Cd and Cm result in force overpredictions for all cases of regular waves with in-line current. For steady sheared current flow through a porous tower, apart from the dominant lateral flow divergence, numerical flow visualisation reveals an existence of vertical flow interaction in the porous tower. This is attributed to the non-uniform loading with water depth and was not observed previously for uniform current flow. This study provides the first experimental validation and justification on the use of a simple porous block in representing a complex geometry of real space-frame structures when exposed to combined large regular waves and in-line current
