L' Adoration des mages, panneau d'une collection privée belge : étude interdisciplinaire autour du panneau central d'un triptyque démembré
No full textL’article présente les résultats de l’étude interdisciplinaire du panneau de l’Adoration des mages issu d’une collection privée belge, menée à l’Institut royal du Patrimoine artistique en 2015. La recherche en histoire de l’art ainsi que l’étude technique de l’œuvre, appuyé sur la documentation de l’imagerie scientifique (RX, RIR), ont permis de mettre en exergue que l’Adoration constituait le panneau central d’un triptyque dont les volets ont aujourd’hui disparu. La comparaison avec les triptyques de Milan et Fécamp permettent de suggérer la composition originale du retable
Evolution des flux de travailleurs frontaliers en Belgique, de 1972 à 1982 [Un essai d'utilisation des statistiques annuelles établies par l'Institut National d'Assurance Maladie-Invalidité (INAMI) ]
No full textEvolution of the movements of Belgian workers who live near the frontier from 1972 to 1982. An attempt to use the yearly statistics of the National Institute for Health and disablement insurance (INAMI).
Abstract : The author offers a summary of the recent evolution (1972-1982) of the movements of the Belgian workers who live near the border in perusing the yearly I. N. A. M.I. statistics. Beyond the preliminary quantitative study of the movements of the active population at the various frontiers of the Belgian Kingdom, R.S. wants to show the demographic profile of this very particular population. A study based on the scale of the Belgian « arrondissement » well localizes the frontier movements.L'auteur propose un bilan de l'évolution récente (1972-1982) des flux de travailleurs frontaliers en Belgique dépouillant les statistiques annuelles de l' INAMI. Au-delà de l'approche quantitative préalable des navettes de population active aux différentes frontières du royaume, R. SEVRIN veut présenter le profil démographique de cette population très particulière. Une étude, menée à l'échelle de l'arrondissement belge, permet de bien localiser les mouvements frontaliers.Sevrin Robert.

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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

We obtain the induced action F [h, b] for chiral W3 gravity in the c~ ___ limit from the induced action of a gauged Sl(3, R) Wess-Zumino-Witten model by imposing constraints on the currents of the latter. In the process we find a closed gauge algebra for the gauge sector of W3 gravity in which the currents T and W become auxiliary fields. An explicit realization of T and W in terms of the gauge fields is given. In terms of new fields r and s, which are a generalization of Polyakov's f variable for ordinary gravity, the complete induced action l-'[h, b; c~ _ 0o] becomes local
Square Dancing with the Stars to Enhance Dynamic Hirschman Linkages?
No full textIn this Presidential Address, the author takes the reader on a reconnaissance of his life and time as a regional scientist. He points out scenery he found scintillating along the way, hoping that some may pick up the banner and chew on a few of the ideas for a while. He suggests a revisit to Albert O. Hirschman’s notion of key sectors and more empirical analysis related to Marcus Berliant’s and Masahisa Fujita’s notion of knowledge creation and transfer.Presidential Address, San Antonio, Texas, March 29, 2014 (53rd Meetings of the Southern Regional Science Association
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

The Field theory limit of multiloop string amplitudes
No full textWe report on recent progress in the use of string techniques for the computation of field theory amplitudes. We show how one-loop renormalization constants in Yang-Mills theory can be computed using the open spinning string, we review the calculation of two-loop scalar amplitudes with the bosonic string, and we briefly indicate how the technique can be applied to the two-loop vacuum bubbles of Yang-Mills theory
