<i>Aralia fragrans</i> (D. Don) Jebb & J. Wen, une nouvelle combinaison dans les Araliaceae.
No full textHedera fragrans D. Don et Aralia leschenaultii (DC.) J. Wen sont identiques, le premier étant nomenclaturalement prioritaire. Une nouvelle combinaison, Aralia fragrans, est ainsi nécessaire. Aralia fragrans appartient à Aralia sect. Pentapanax et est largement distribué en Asie, y compris le Bengladesh, Bhutan, la Chine (Yunnan), l\u27Inde, le Nepal, le Sri Lanka, la Thailande du nord (Chiang Mai), et le Nord Vietnam (Lao Cai). Cette espèce semble très affine de Aralia kingdon-wardii J. Wen, Lowry & Esser.Hedera fragrans D. Don and Aralia leschenaultii (DC.) J. Wen are identical, but the former has nomenclatural priority.

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

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
