Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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

Downscaling ERA-5 reanalysis data for coastal climate applications (and evaluation of uncertainty of coastal data)
Full text linkThe management of coastal zones requires precise data concerning past wind/wave regimes and future climate trends. Many studies have been based on low resolution reanalysis data that cannot allow a detailed description of the variability induced by local conditions. We present a feasibility study where a simple dynamical downscaling of ERA5 reanalysis data is applied through a cascade of regional atmospheric/wave models. A long-term goal of this study is to identify the long-term trends in the last 30-35 years in order to better understand the effects linked to the impact of climate change along the coast. The methodology applied is based on:- a high resolution atmospheric model (WRF-ARW), run at a horizontal resolution of about 3 km;- a finite element wave model (WW3), able to compute high-resolution waves along the coast, at a resolution up to 300-400 meters. Our target area is the North-Western Mediterranean, characterized by a marked variability in wind/wave regimes. The evaluation period is 3 months and the quality assessment has been performed by using regional observed data (coastal buoys and anemometers).
Results show that regional downscaled data provide lower errors in the mean wave parameters and wind regimes with respect to global data and some significative improvements with respect to studies based on past reanalysis data. Moreover we present results concerning the use of the multiple members of the ERA5 data to improve the downscaled information

Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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
