R-équivalence simultanée de torseurs: un complémentà l'article de P. Gille
No full textRésuméSi K est un corps fertile («large field») et G un groupe fini, on montre que toute famille finie de G-torseurs sur K, qui sont R-équivalents, s'obtient par spécialisation à partir d'un G-torseur géométriquement irréductible sur un ouvert de P1K. Ceci répond notamment à une question de P. Gille (2001, J. Number Theory91, 284–292). Les énoncés sont ensuite reformulés en termes de R-équivalence de points rationnels sur les variétés de la forme GLr, K/G.© 2001 Elsevier Science.If K is a “large” field and G is a finite group, we show that any finite family of R-equivalent G-torsors over K is obtained by specialization from a geometrically irreducible G-torsor over an open subset of P1K. This answers a question of P. Gille (2001, J. Number Theory91, 284–292). The results are also stated in terms of R-equivalence of rational points on varieties of the form GLr, K/G

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

"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
Arithmetical birational invariants of linear algebraic groups over two-dimensional geometric fields
No full textAbstractLet G be a connected linear algebraic group over a geometric field k of cohomological dimension 2 of one of the types which were considered by Colliot-Thélène, Gille and Parimala. Basing on their results, we compute the group of classes of R-equivalence G(k)/R, the defect of weak approximation AΣ(G), the first Galois cohomology H1(k,G), and the Tate–Shafarevich kernel ш1(k,G) (for suitable k) in terms of the algebraic fundamental group π1(G). We prove that the groups G(k)/R and AΣ(G) and the set ш1(k,G) are stably k-birational invariants of G
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
