Globalization in an Age of Crisis: Multilateral Economic Cooperation in the Twenty-First Century
Get PDFCoping with Shocks and Shifts: The Multilateral Trading System in Historical Perspective
Get PDFThis paper provides a historical look at how the multilateral trading system has coped with the challenge of shocks and shifts. By shocks we mean sudden jolts to the world economy in the form of financial crises and deep recessions, or wars and political conflicts. By shifts we mean slow-moving, long-term changes in comparative advantage or shifts in the geopolitical equilibrium that force economies to undergo disruptive and potentially painful adjustments. We conclude that most shocks (financial crises and regional wars) have had relatively little effect on trade policy, but that shifts pose a greater challenge to the system of open, multilateral trade.
Asteroseismic models for the exoplanet host star HD 19994: A preliminary approach
No full textInternational audienceWe present preliminary models for HD 19994, a star which is part of a binary system and also harbors an extrasolar planet. We compute evolutionary tracks with the Toulouse-Geneva evo- lution code, using four different metallicity values. Large and small separations are computed, and the echelle diagrams are given for a few models. From the currently known spectroscopic data, we found that HD 19994 could be either an overmetallic main sequence star with a mass range between 1.24 and 1.36 Mȯ or a less massive subgiant star, with a mass range of 1.18-1.28 Mȯ and a solar metallicity. We also found that, in some cases, the small separations can become negative at a given frequency, which is related to the presence of a convective and helium-rich core. This is a preliminary approach: a more precise asteroseismic study of this star, based on recent (November 2007) data from the HARPS spectrograph will be given later

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
