CCD UBV and Gaia DR3 based analysis of NGC 189, NGC 1758 and NGC 7762 open clusters
This paper presents photometric, astrometric, and kinematic analyses of the open clusters NGC 189, NGC 1758 and NGC 7762 based on CCD UBV photometric and Gaia Data Release 3 (DR3) data. According to membership analyses, we identified 32, 57 and 106 most probable member stars with membership probabilities P⩾0.5 in NGC 189, NGC 1758 and NGC 7762, respectively. The color excesses and photometric metallicities of each cluster were determined separately using UBV two-color diagrams. The color excess E(B-V) is 0.590±0.023 mag for NGC 189, 0.310±0.022 mag for NGC 1758 and 0.640±0.017 mag for NGC 7762. The photometric metallicity [Fe/H] is -0.08±0.03 dex for both NGC 189 and NGC 1758, and -0.12±0.02 dex for NGC 7762. Distance moduli and ages of the clusters were obtained by comparing PARSEC isochrones with the color-magnitude diagrams constructed from UBV and Gaia photometric data. During this process, we kept as constant color excess and metallicity for each cluster. The estimated isochrone distance is 1201±53 pc for NGC 189, 902±33 pc for NGC 1758 and 911±31 pc for NGC 7762. These are compatible with the values obtained from trigonometric parallax. Ages of the clusters are 500±50 Myr, 650±50 Myr and 2000±200 Myr for NGC 189, NGC 1758 and NGC 7762, respectively. Galactic orbit integration of the clusters showed that NGC 1758 completely orbits outside the solar circle, while NGC 189 and NGC 7762 enter the solar circle during their orbits

CCD UBV and Gaia DR3 based analysis of NGC 189, NGC 1758 and NGC 7762 open clusters
This paper presents photometric, astrometric, and kinematic analyses of the
open clusters NGC 189, NGC 1758 and NGC 7762 based on CCD UBV photometric and
Gaia Data Release 3 (DR3) data. According to membership analyses, we identified
32, 57 and 106 most probable member stars with membership probabilities in NGC 189, NGC 1758 and NGC 7762, respectively. The color excesses and
photometric metallicities of each cluster were determined separately using UBV
two-color diagrams. The color excess is mag for NGC
189, mag for NGC 1758 and mag for NGC 7762.
The photometric metallicity [Fe/H] is dex for both NGC 189 and
NGC 1758, and dex for NGC 7762. Distance moduli and ages of
the clusters were obtained by comparing PARSEC isochrones with the
color-magnitude diagrams constructed from UBV and Gaia photometric data. During
this process, we kept as constant color excess and metallicity for each
cluster. The estimated isochrone distance is pc for NGC 189, pc for NGC 1758 and pc for NGC 7762. These are compatible
with the values obtained from trigonometric parallax. Ages of the clusters are
Myr, Myr and Myr for NGC 189, NGC 1758
and NGC 7762, respectively. Galactic orbit integration of the clusters showed
that NGC 1758 completely orbits outside the solar circle, while NGC 189 and NGC
7762 enter the solar circle during their orbits.Comment: 25 pages, 11 figures and 6 tables, accepted for publication in

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
Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
RADIAL VELOCITIES AND METALLICITIES OF RED GIANT STARS IN THE OLD OPEN CLUSTER NGC 7762
We present and discuss radial velocity and the very first metallicity measurements for nine evolved stars in the poorly known old open cluster NGC 7762. We isolated eight radial velocity cluster members and one interloper. Radial velocities are in good agreement with previous studies. NGC 7762 turns out to be of solar metallicity within the uncertainties ([Fe/H] = 0.04 ± 0.12). For this metallicity, the cluster age is 2.5 ± 0.2 Gyr, and falls in an age range where only a few old open clusters are known. With respect to previous studies, we find a larger distance, implying the cluster is located {900}-50+70 pc from the Sun. For most of the elements we measure solar-scaled abundance ratios. We searched the literature for open clusters of similar age in the solar vicinity and found that NGC 7762 can be considered a twin of Ruprecht 147, a similar age cluster located only 300 pc from the Sun. In fact, as well as age, metallicity and abundance ratios are very close to Ruprecht 147 values within the observational uncertainties
