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

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
Survey of pulmonate snails of central Minnesota .1. Lymnaeidae
No full textAquatic snails were collected at 148 sites from various wetland habitats in central Minnesota between May and September, 1988. Ten lymnaeid species were collected, including Lymnaea palustris, L. stagnalis, L. exilis, L. caperata, L. catascopium, L. megasoma, L. Fossaria modicella, L. (F.) parva, L. (F.) bulimoides, and L. (F.) dalli. These species were found at 30-, 18-, 15-, 12-, 11-, 7-, 20-, 9-, 1.4-, and 0.7% of the collection sites, respectively. Lymnaeids were found most frequently in still water of near neutral pH with a small particle size substrate. However, individual lymnaeid species showed great variability in habitat type selection. Lymnaea megasoma and L. exilis were found in slightly acidic water. Lymnaea catascopium was found in the deeper open water of lakes and slow moving rivers, while L. caperata and L. (Fossaria) spp. were found in temporary wetlands and mud flats. Wetland habitat reduction during the drought of 1987-1989 may have influenced distribution of the amphibious species. Those species recovered from shallow temporary wetlands in this study may have a wider distribution during periods of normal rainfall.PT: J; CR: BAKER FC, 1911, CHICAGO ACAD SCI SPE, V3 BAKER FC, 1929, NAUTILUS, V4, P95 BAKER FC, 1929, NAUTILUS, V42, P131 BAKER FC, 1935, AM MID NAT, V16, P256 BAKER FC, 1936, NAUTILUS, V49, P127 BURCH JB, 1980, WALKERANA, V1, P81 BURCH JB, 1982, T POETS SOC, V1, P217 CLARKE AH, 1973, MALACOLOGIA, V13 DANIELS LE, 1909, NAUTILUS, V22, P119 DAWLEY C, 1947, AM MIDL NAT, V38, P671 EDDY S, 1982, TAXONOMIC KEYS COMMO EGGERS SD, 1987, WETLAND PLANTS PLANT SARGENT HE, 1895, NAUTILUS, V9, P87 SARGENT HE, 1995, NAUTILUS, V9, P125 SHAW S, 1971, 39 US DEP INT FISH W; NR: 15; TC: 2; J9: J FRESHWATER ECOL; PG: 9; GA: HK695Source type: Electronic(1
