Observations and light curve solutions of the eclipsing binaries USNO-B1.0 1395-0370184 and USNO-B1.0 1395-0370731
We present follow-up photometric observations in Sloan filters g', i' of the
newly discovered eclipsing stars USNO-B1.0 1395-0370184 and USNO-B1.0
1395-0370731. Our data revealed that their orbital periods are considerably
bigger than the previous values. This result changed the classification of
USNO-B1.0 1395-0370184 from ultrashort-period binary (P=0.197 d) to
short-period system (P=0.251 d). The light curve solutions of our
observations revealed that USNOB1.0 1395-0370184 and USNO-B1.0 1395-0370731
are overcontact binaries in which components are K dwarfs, close in masses
and radii. The light curve distortions were reproduced by cool spots with
angular radius of around 20°

Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
