Ecosostenibilità come obiettivo progettuale
No full textVengono analizzate le caratteristiche di progetti di quartieri che vantano un elevato livello di complessità e l’obiettivo dell’ecosostenibilità è assunto come uno dei focus fondamentali. Tale approccio implica una forte attenzione al luogo e alle sue specificità bioclimatiche, che definiranno caratteristiche fondamentali del quartiere come la disposizione degli edifici, le tecnologie adottate, i materiali scelti. La termoregolazione naturale di un quartiere richiede un’adeguata lettura del circostante e una notevole perizia, ma i suoi benefici sono tali da poter quasi annullare la spesa energetica per la climatizzazione. I quartieri con questo livello di progettazione, pertanto, necessitano di poche tecnologie, con un notevole risparmio economico: i soldi così risparmiati, generalmente, sono destinati alle aree comuni che si arricchiscono di funzioni, anche complesse, come molte funzioni produttive (agricoltura comune, laboratori, officine specializzate, agenzie di comunicazione). Molti di questi insediamenti, infatti, vantano servizi estremamente avanzati, da quelli di assistenza a quelli culturali; grande rilievo è attribuito alla formazione e all’educazione dei cittadini: a prescindere da tutti i connotati progettuali e tecnici, pertanto, questi quartieri si distinguono dagli altri soprattutto perché considerano la sostenibilità una scelta consapevole

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

No full textVariations 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
