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
Country profile : Italy
Along with a number of other countries, particularly those in southern Europe, Italy has only been a receiving country for international immigration for about 25 years. Italy itself has a long tradition of emigration and it is estimated that there are currently about 60 million Italian emigrants all over the world. In Italian Law, the concept of "immigrant" first appeared as recently as 1986. Previously there was only the general juridical type of the "foreigner", whose residence within the national boundaries was governed by public security law. In the Italian public discourse, up to the end of the 1980s, "immigrants" were internal migrants from less developed southern regions ("Mezzogiorno") who moved towards the more dynamic areas of Northern Italy, a huge phenomenon throughout the twentieth century, and particularly intense in the "golden period" of the industrial development (from the 1950s and the first half of the 1970s): initially migration was mainly towards the so called "industrial triangle" (Milan-Turin-Genoa), afterwards it was also towards the central and north-eastern regions, characterized by the growth of small companies and industrial districts. Based on a historical analysis, we know that today’s aversions and oppositions towards foreign immigrants were directed to migrants from the south of Italy in the past. However, in those times immigration was not a central issue in the political debate, essentially because the internal migrants were citizens and voters and they might be employed as civil servants. The phenomenon of international migration has therefore developed in a national context characterized by certain aspects that should be taken into account throughout the analysis
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
Appropriate Similarity Measures for Author Cocitation Analysis
We 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

Dispelling the Myths Behind First-author Citation Counts
We 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
