Erratum to: Lava discharge during Etna’s January 2011 fire fountain tracked using MSG-SEVIRI
No full textIn the paper by Gouhier, M., Harris, A., Calvari, S., Labazuy,
P., Guéhenneux, Y., Donnadieu, F., Valade, S, entitled “Lava
discharge during Etna’s January 2011 fire fountain tracked
using MSG-SEVIRI” (Bull Volcanol (2012) 74:787–793,
DOI 10.1007/s00445-011-0572-y), we present data from a
Doppler radar (VOLDORAD 2B). This ground-based Lband
radar has been monitoring the eruptive activity of the
summit craters of Mt. Etna in real-time since July 2009 from a
site about 3.5 km SSE of the craters. Examples of applications
of this type of radar are reviewed by Donnadieu (2012)
and shown on the VOLDORAD website (http://wwwobs.
univbpclermont.fr/SO/televolc/voldorad/).
Although designed and owned by the Observatoire de
Physique du Globe in Clermont-Ferrand (OPGC), France,
VOLDORAD 2B is operated jointly with the INGV-Catania
(Italy) in the framework of a technical and scientific collaboration
agreement between the INGV of Catania, the French
CNRS and the OPGC-Université Blaise Pascal in Clermont-
Ferrand. The system also utilizes a dedicated micropatch
antenna designed at the University of Calabria (Boccia et al.
2010) and owned by INGV. The objective of the joint acquisition
of the radar data by INGV-Catania and the OPGC is
twofold: (1) to mitigate volcanic risks at Etna by better assessing
the hazards arising from ash plumes and (2) to allow detailed
study of volcanic activity and its environmental impact.
In the paper by Gouhier et al. (2012), we failed to
highlight this important collaboration between the INGV
Catania and the OPGC; a cooperation essential for the past,
current and future generation of such valuable data sets.
Specifically we wish to acknowledge the roles of Mauro
Coltelli, Michele Prestifilippo and Simona Scollo for their
important input into this project, and pivotal role in setting
up, and maintaining, this collaborative deployment.Published12611.5. TTC - Sorveglianza dell'attività eruttiva dei vulcaniJCR Journalrestricte

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
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

Mapping the Discipline of the Olympic Games An Author-Cocitation Analysis
No full textThe 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
