This post takes a look at the Eigenfactor score of journals against their prices and finds that there is a very weak correlation. So weak that there is probably no actual correlation between journal prices and the quality of the research within them.
In my last several posts I discussed how the Thomson Reuter’s Journal Impact Factors (TRJIF) and the 5 year impact factor has no correlation with the prices of journals. Well, Thomson Reuter’s is not the only metric for measure the presumed quality of journals, there is also Eigenfactor score. This not only looks at citations, but at the quality of those citations by using a page rank algorithm. Basically, are journals receiving citations from other high ranked journals.
As before the these scores were compared against the price of journals and price per page. Since, the same database was used as the Thomson Reuter’s the same twelve journals were used again.
|Archaeology, Ethnology and Anthropology of Eurasia||
|The Journal of the Polynesian society||
|Archaeology in Oceania||
|International Journal of Osteoarchaeology||
|Journal of Material Culture||
|Journal of Archaeological Method and Theory||
|Journal of Anthropological Archaeology||
|Journal of Archaeological Science||
These results for the Eigenfactor are slightly better for commercial publishers then with the Impact Factor but still the results are not positive. A very weak correlation is observed with over all journal price and an even weaker one is seen for cost per page.
Weak R^2 means there is probably no corrilation between journal prices and this measurement of journal quality.
