Di chi è la tua attenzione? La sociologia cognitiva di Eviatar Zerubavel alla prova dell’attenzione
The chapter focuses on the work of Eviatar Zerubavel and his compelling contribution to study of the way we think, our perceptual and cognitive processes, always developed within social contexts, and therefore the shaping of individual attention is not only about the (possibly nefarious) effects of digital technology but has a much longer history that cannot be ignored
Nascosto alla luce del sole. La struttura sociale dell’irrilevanza
Spesso diamo per scontato che ciò che percepiamo sia una rappresentazione fedele del mondo. Eppure, a chi non è capitalo di cercare disperatamente le chiavi o gli occhiali per poi scoprire che si trovavano letteralmente di fronte ai nostri occhi? I nostri organi di senso sono incredibilmente potenti, ma non basta guardare qualcosa per notarla: la nostra mente è selettiva, stabilisce costantemente delle priorità e organizza le informazioni che recepiamo. Alcune cose, che riteniamo rilevanti, vanno in primo piano mentre altre – pensate come
irrilevanti – rimangono sullo sfondo. Che cosa determina, in ultima analisi, ciò che percepiamo e cosa invece ignoriamo? In questo libro affascinante, il noto sociologo Eviatar Zerubavel invita ad esplorare tale questione da una prospettiva insolita: ciò che percepiamo non dipende solo dalla biologia dei nostri organi di senso, ma anche dalla nostra natura sociale. Attraverso una grande quantità di esempi tratti dalla scienza, dal mondo della vita quotidiana, dall’arte e dalle illusioni ottiche, Zerubavel mostra come ciò che notiamo o ignoriamo varia tra
le diverse culture e nel corso della storia. In definitiva, l’ambiente in cui viviamo – il nostro stile di vita, la professione, la nazionalità – giocano un ruolo nel determinare nel modo in cui accediamo al mondo attraverso i sensi
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
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
