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
Autolesività non suicidaria (NSSI) e disturbo da comportamento suicida (SBD) nella recente pubblicazione del DSM-5
No full textNon-suicidal self-injury (NSSI) and suicidal
behavior disorder (SBD) have been included
as diagnostic categories as conditions for
further study in the diagnostic and statistical
manual of mental disorders (DSM-5). Both
behaviors were defined for the first time in
a classificatory system to standardize further
research in this field, but are not recognized
as a clinical entity yet. The aim of this paper
was to introduce both concepts and to address
some discussions preceding their introduction
in DSM-5. Further we present some
data on the prevalence of NSSI and SBD. A
literature research was conducted in order to
compare existing studies using the published
criteria for NSSI and SBD to understand the
prevalence of both conditions. Globally, our
results showed that the comparability of
prevalence studies is limited, since different
criteria for NSSI and SBD have been utilized
in the years before inclusion into DSM-5. The
introduction of NSSI and SBD as diagnosis
will lead to a better comparability of future
studies. Especially the implementation of
NSSI as a diagnostic entity would allow to
avoid premature labeling of adolescent patients
with the diagnosis of Borderline Personality
Disorder. Further, the recognition
of these independent diagnoses can help to
consider them as prognostic factors of psychiatric
disorders, as well as risk factors for
completed suicide. From the perspective of
prevention, we conclude that the standardization of the definitions of both behaviors will
spark urgently needed intervention studies
in order to develop more specific therapeutic
treatments for adolescents and adults with
NSSI and SBD

No full textDispelling 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
