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
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
Video-based quantification of body movement indicates negative symptoms: a replication
No full textObjective: In schizophrenia, abnormalities in nonverbal behaviors
have always been considered as highly relevant. However, due to
methodological limitations, nonverbal behavior was rarely quantified
objectively. Recent methodological advances now allow a quantification
of body movement from ordinary video recordings. We
showed that patients’ objectively measured amount of movement in
social role-play interactions was closely associated with their symptom
profiles (Kupper, Ramseyer, Hoffmann, & Tschacher,
Schizophrenia Research 2010). In the present study, a replication of
these results in the context of semi-standardized PANSS (Positive and
Negative Syndrome Scale) interviews was intended.
Methods: 17 patients with schizophrenia were analyzed during the
initial 15-min sequence of a videotaped PANSS interview using
Motion Energy Analysis (MEA). The amount of patients’ movement
was then correlated with their PANSS symptom scores.
Results: Sizeable and significant correlations between negative symptoms
and reduced movements (r = -.68, p<0.01) and reduced
movement speed (r = -.80, p<0.001) were found. Moreover, cognitive
symptoms were related to reduced movement speed (r = -.70, p<.01).
Conclusion: Negative symptoms were reliably indicated by patients’
nonverbal behavior in psychopathology interviews. Hence, the main
result of our earlier study, examining patients’ nonverbal behavior in
role play tests, was replicated for the less structured interactions in
psychopathological interviews. Results could encourage the use of
MEA in a wide range of videotaped social interactions of patients
with schizophrenia and other psychiatric disorders
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
