New papers published in the ejournal Cybermetrics

[Isidro F. Aguillo]

Dear colleagues,

Due to circumstances out of our control, the url of the electronic 
journal has changed to
http://cybermetrics.cindoc.csic.es/.
Please update your records accordingly.

There are two new papers that can be of your interest:
Levene, M.; Fenner, T. & Bar-Ilan, J. (2012). A bibliometric index based 
on the complete list of cited Publications. Cybermetrics, 16(1):Paper 1

We propose a new index, the j-index, which is defined for an author as 
the sum of the square roots of the numbers of citations to each of the 
author’s publications. The idea behind the j-index it to remedy a 
drawback of the h-index - that the h-index does not take into account 
the full citation record of a researcher. The square root function is 
motivated by our desire to avoid the possible bias that may occur with a 
simple sum when an author has several very highly cited papers. We 
compare the j-index to the h-index, the g-index and the total citation 
count for three subject areas using several association measures. Our 
results indicate that that the association between the j-index and the 
other indices varies according to the subject area. One explanation of 
this variation may be due to the proportion of citations to publications 
of the researcher that are in the h-core. The j-index is not an h-index 
variant, and as such is intended to complement rather than necessarily 
replace the h-index and other bibliometric indicators, thus providing a 
more complete picture of a researcher’s achievements

Moskovkin, V. M.; Delux, T. & Moskovkina, M. V. (2012). Comparative 
Analysis of University Publication Activity by Google Scholar (On 
Example of Leading Czech and Germany Universities). Cybermetrics, 
16(1):Paper 2

With the help of the Google Scholar search engine, we have studied in 
detail the aggregated publication structure of the leading universities 
in the Czech Republic and Germany. We have also classified these 
structures and identified structural changes in them for German 
universities. These shifts have been observed in the Free University of 
Berlin and Humboldt University, and they all occurred within 5 years in 
the first decade of the 21st century when the major university 
publication activity moved from the sphere of medical research to the 
area of social sciences and humanities. Prospects for further research 
are in the comparative analysis of university publication activities 
with the help of Web of Science, Scopus and Google Scholar facilities.
