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
Pro Urbe Magica. Quando l’arte disfa il presente tecno-capitalista attraverso il reincanto critico
No full textNelle pagine di questa tesi proverò ad avventurarmi nel tentativo di ricostruire una delle possibili storie di come sia nato un certo modo magico di fare architettura e urbanità a partire dai linguaggi artistici e quando sia emersa, invece, la separazione tra queste dimensioni un tempo unite in un fare relazionale e sensibile, strutturando la disincantata dicotomia tra estetica e politica. Si tratterà di prendere sul serio il ruolo che l’arte potrebbe avere nella possibilità di reincantare l’urbano immaginando e costruendo stati magici d’immanenza ovvero luoghi e momenti in cui fare esperienza delle forze della vita in sé (Deleuze e Guattari 1969). Per fuggire alla cattura tecno-capitalista e superare l’ontologia diabolica che si è imposta, nel presente, come unico modo trascendente di abitare il mondo, l’ipotesi avanzata è che la via più percorribile potrebbe essere proprio quella di ripartire dal punto in cui la forbice si è divaricata, ricostruendo il legame tra estetica e politica. L’idea che percorre l’intera tesi infatti è che, fin dalle origini, l’arte ha generato diversamente architettura e urbanità ricreando stati d’unione magici e che questa pratica progettuale, quasi del tutto dimenticata dagli architetti e dagli urbanisti ipnotizzati dalla trascendenza della tecnica, viene ciclicamente riattivata da artiste, filosofe e poeti capaci di vedere quello che c’è al di là delle separazioni imposte dal disincanto e di creare nuovi stati urbani d’immanenza. A questa possibilità, sempre destituente prima di farsi istituente, di salpare Pro Urbe Magica osservando il potenziale eversivo dell’arte nel disfare il presente e creare spazi di reincanto critico oltre la cattura tecno-capitalista, saranno dedicate le pagine di questa tesi
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
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
