Formulazione di un modello a reti neurali per il sistema delle imprese presenti nel distretto agro-alimentare del piceno.
L'ipotesi che è alla base di questo lavoro è che un distretto industriale sia un CAS (complex adaptive system) e che la sua capacità di comprensione e di analisi dell'ambiente economico in cui si trova a competere sia il frutto di una sorta di “swarm intelligence”.
Per studiare tale possibilità viene proposta la formulazione di un modello del distretto preso in esame (i.e. il distretto agro-alimentare del Piceno, nelle Marche) costruendo uno schema di rete neurale che possa fungere allo scopo
Contro la diseguaglianza: fondamenti storici e linee di ricerca in economia circolare
Questo breve saggio guarda alla genesi storica delle
idee relative alla CE prendendo in considerazione l’esistenza di
approcci simili, ma con finalità diverse e più sfumate, tra una
presunta prima fase di sviluppo della CE stessa (1.0) e una seconda
(2.0). La diversa declinazione tra le due CE consiste nell’immissione
nella 2.0 del problema delle diseguaglianze facendo
intuire che, in tale prospettiva, si rende necessario un approfondimento
più mirato anche nella ricerca dei fondamenti storici

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
