No full textWe propose a nonperturbative procedure to fix generic covariant gauges on the lattice. Varying the gauge parameter, this gauge fixing provides a concrete method to check numerically the gauge dependence of correlators measured on the lattice. The new algorithm turns out to converge with a good efficiency. As a preliminary physical result, we find a sensitive dependence of the gluon propagator on the gauge parameter. ©2000 The American Physical Society
Ricerca & Innovazione nella Politica di Coesione 2014-2020. Quanto conteranno le questioni di genere?
No full textLa ricerca e l’innovazione (R&I) costituiscono una delle quattro
priorità-chiave della Politica di Coesione 2014-2020 che ha come obiettivo
generale la crescita economica e l’occupazione. Le università saranno beneficiarie
d’investimenti per R&I, perché sono sede di enormi patrimoni di conoscenze e
concentrano numeri elevati di giovani adulti in formazione, dai quali ci si aspetta
la capacità di affrontare i problemi della società con vigore e preparazione. La
Commissione europea e l’OECD ritengono essenziale che l’innovazione sociale
debba entrare nelle università, per stimolare la creatività e lo spirito d’iniziativa
mettendo in gioco tutto il capitale umano disponibile. Purtroppo, il rapporto SHE
figures 2012 della Commissione europea indica che tutto il sistema accademico
europeo è caratterizzato da disparità di genere, che si accentua passando dalle fasi
iniziali a quelle finali della carriera. Questa disparità nasce da opacità nelle
decisioni, pregiudizi, scarsa conoscenza dei fatti. In questo clima relazionale,
sorgono dei dubbi molto seri sulla capacità delle università di realizzare quelle
innovazioni sociali e tecnologiche, da cui dipende la possibilità di stimolare
l’economia e far aumentare i posti di lavoro, come voluto dalla Politica di
Coesione 2014-2020
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
