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
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
The downfall of the law of 19 february 2004 n. 40: between ratio legis and parallelism whith nonequivalent legal devices [La caduta delle legge 19 febbraio 2004 n. 40: tra ratio legis e analogie con istituti non equiparabili medico]
No full textBecause of its rigour, the Italian law bearing the denomination “Regula-tions on medically assisted reproduction” has been strongly debated from the very beginning and gradually dismantled by jurisprudence. In this article, the authors re-mark that the path followed by jurisprudence is characterized by the total absence of care regarding the unborn child’s rights. The authors rather suggest that the ap-proach of jurisprudence should be guided by considerations on the substance of the law at issue, investigating all the issues involved, including those concerning the posi-tion of the unborn baby, as stated by the ratio of the same law
PE-CVD of acid/base coatings from Acrylic Acid and Allylamine vapors
No full textDifferent plasma processes were investigated to obtain coatings characterized by N- and O-functional groups at their surface. From the literature, big efforts are evident devoted to designing new surfaces with chemical composition and chemical-physical properties tightly controlled. This paper demonstrates how it is possible to obtain coatings with acid and basic properties at different extent, by simply adjusting the acrylic acid/allylamine chemical composition of the gas feed in a plasma deposition process. The deposited films exhibit tuneable acid-base properties, very attractive to manufacture sensors, and biomaterials, and for applications in tissue engineering field
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
