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
Enriching sociology by studying the super-rich. Introduction
Full text linkraditionally, sociology has focused on the middle and working classes, but the disproportionate influence of the super-rich calls for a deeper analysis. This Introduction highlights how this elite holds significant control over economic, cultural, and political resources, influencing global social dynamics. Additionally, it discusses how the wealth of the super-rich translates into political power and how their consumption choices impact the environment and society. Finally, it emphasizes the importance of examining the origins, reproduction, and responsibility of this elite to better understand contemporary inequalities. By providing an overview of the three contributions to the Special Issue by Khan and O'Brian, Mears and Delpierre, it offers a perspective on the most relevant issues related to the role of the super-rich and the dynamics that sustain their privileges
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
Visioni di genere e forme della femminilità : soggetti, codici, significati
No full textLe immagini delle soggettività sono tipicamente codificate in base al genere. Molte sono le nozioni di “genere” (gender) che si sono attestate in letteratura. Prima di riflettere sui “codici” visivi attraverso cui si costruisce culturalmente un’immagine di genere sono quindi utili alcune premesse. Le prime, e più ovvie, riguardano la posizione teorica in cui ci collochiamo, vale a dire una prospettiva che cerca di coniugare e integrare la sociologia, la semiotica, gli studi di genere e la critica femminista. Ed è perciò un tipo di sguardo che pensa il genere come l'insieme dei significati sociali e culturali associati al femminile e al corpo femminile, o, meglio, come la somma dei suoi abiti, e cioè delle interpretazioni che nel corso della storia hanno di volta in volta definito la sessualità e il corpo delle ‘donne’ rispetto, in contrapposizione o in opposizione a quello degli ‘uomini’. Il soggetto femminile si costituisce e agisce cioè come soggetto sessuato introiettando determinate rappresentazioni del proprio genere e della propria sessualità eterosessualmente normata, facendole proprie. In questo capitolo, dopo una breve introduzione su alcuni strumenti semiotici di analisi dell’immagine, riprenderemo alcuni dei più classici studi sulla rappresentazione visuale del femminile e del genere, e in particolare quelli di Laura Mulvey, di Ervin Goffman e di Teresa de Lauretis
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
