Trend towards multiple authorship in occupational medicine journals
No full textAbstract Background There is an established trend towards an increasing number of authors per article in prestigious journals for medicine and health sciences. It is uncertain whether a similar trend occurs to the same extent in journals for specific medical specialties. Methods Journals focusing on occupational medicine were selected for analysis with regard to single or multiple-authorship per peer-reviewed paper. Data were collected from PubMed for publications between 1970 and 2007. These were analysed to calculate the average number of authors per multiple-author article per year and the percentage of single-author articles per year. The slope and average of these journals were then compared with that of previously studied non-occupational medicine journals. Results The results confirm a trend towards a linear increase in the average number of authors per article and a linear decrease in the percentage of single-author articles. The slope for the average number of authors for multiple-author articles was significantly higher in the Journal of Occupational and Environmental Medicine than in the other occupational medicine journals. Computational analysis of all articles published showed that Occupational Medicine (Oxford) had a significantly higher percentage of single-author articles than the other occupational medicine journals as well as major journals previously studied. Conclusion The same trend towards multiple authorship can be observed in medical specialty journals as in major journals for medicine and health sciences. There is a direct relationship between occupational journals with higher impact factors and a higher average number of authors per article in those journals.</p
The nomenclature of the lycophyte species Phlegmariurus mingcheensis Ching (Huperziaceae)
No full textIn 1982, Ren Chang Ching twice described the same lycophyte species under the names Lycopodium mingcheense (published in April; the original "minchegense" spelling being a correctable error) and Phlegmariurus mingcheensis Ching (published in May). Phlegmariurus mingcheensis cannot be taken as a combination based on Lycopodium mingcheense because in the original publication a different holotype was indicated and the name Lycopodium mingcheense was not mentioned. The correct names for this species in Huperzia, Lycopodium, and Phlegmariurus are Huperzia mingcheensis (Ching) Holub (basionym: Phlegmariurus mingcheensis), Lycopodium mingcheense Ching, and Phlegmariurus mingcheensis Ching, respectively. The recent lectotypification of the name Lycopodium mingcheense using P.S. Chiu 2069 (PE) was redundant since this specimen was clearly indicated as the holotype in Ching's original publication. The recent new name Phlegmariurus mingjoui X.C. Zhang is an illegitimate superfluous name

Mapping the Discipline of the Olympic Games An Author-Cocitation Analysis
Get PDFThe authors conducted an author cocitation analysis on prominent authors writing about the Olympics during the 1990s. Author cocitation is an established bibliometric technique that can be used to measure the relative similarities of topics written about by the cited authors. This enables a visual representation of the “intellectual space” of the discipline, in this case the Olympics, to be created for the period under review. So core and peripheral research areas are identified, along with their major contributors. The representation appears as a two-dimensional cluster-enhanced map. Subject expertise was then applied to the results to place labels on the generated clusters of authors and their topics
