Dopo il paesaggio l'architettura
No full text“Il paesaggio non esiste”, così esordiva un saggio di Emilio Battisti, architetto-progettista milanese invitato a dare il suo contributo teorico alla prima edizione del LId’A nel 20025. In quella affermazione netta, decisa, provocatoria quanto basta a catalizzare le curiosità, le affinità, le aderenze e i distinguo dei tanti studiosi della materia, può condensarsi il nucleo fondativo di un dibattito che, animando le indagini sul territorio negli ultimi decenni, ha per certi versi paralizzato un pensiero operativo sul territorio. Consapevoli che tutti i punti non possono diventare luoghi è necessario affermare che tutto non può essere paesaggio. L’estinzione delle grandi urgenze della città moderna, i temi connessi alla limitatezza delle risorse, la dimensione ecologica, esautorando le proiezioni urbanistiche a lungo termine, hanno incluso le indagini sul territorio nella dimensione salvifica del paesaggio inglobando in essa la scala dell’architettura. Questa, privata della necessità di rispondere ad una precisa esigenza funzionale, ha avvolto il suo statuto linguistico nell’inseguimento di modelli riflettenti le pratiche espressionistiche dell’arte confluenti in un grado zero della sua scrittura riconoscibile in una estetica della sparizione della sua presenza sul territorio. Il sistema dei collegamenti infrastrutturali e le dovute sinergie con l’esistente, la messa in sicurezza dei suoli in riparo al dissesto idrogeologico del territorio, il contenimento della dispersione urbana con la conseguente rimodulazione delle aree di margine, il restauro del Moderno, la demolizione di ampi brani di costruito, il recupero dei centri storici collinari, la reinterpretazione del patrimonio archeologico in una accezione di fruibilità contemporanea, delineano le propedeuticità di una chirurgica discesa di scala in opposizione alle estensive, quanto aleatorie, politiche di salvaguardia prive di gerarchie di intervento. In tale quadro, dopo la lunga stagione ad appannaggio delle scienze che si occupano del territorio, auspicare una provocatoria fine del paesaggio consente di riposizionare le priorità applicative sulla scala dell’architettura
Notes on the Critique of Revisionism: Lenin, Mao and Us

subjective body of the communism of the Twentieth century in at least
two turning points, the October Revolution and the Cultural Revolution.
The author examines the common points and the singularities of

The Area of the Strait Reading Theories and Strategies for a Metropolitan Dimension
No full textAbstractExtending across a peninsular strip going from Gioia Tauro to Melito Porto Salvo on the Calabrian side, and from Milazzo to Giardini Naxos on the Sicilian side, the Strait of Sicily sees theAspromonte massif and the Peloritani mountain range as two facing stage sets of land sketching in the gulf a water piazza of a landscaping room. Described in the proposal by Giuseppe and Alberto Samonà, Ludovico Quaroni, Antonio Quistelli, Sergio Musmeci, Paolo D’Orsi Villani and Leonardo Urbani, it outlines, in the county seats of Reggio Calabria and Messina, the prevalence of a Euclidean space, identifiable in the exact metrics given by the recurrence of the measuring step of the blocks drawn in the reconstruction plans. The geographical dimension and the human nature of the district identify into the longitudinal extension the characterizing element of a territory and with it the main issue of its own logistics coverage. In this scenario the water piazza of the Strait is cut through on a daily basis by the network linking the two sides, like strings of commuter traffic between two strips of land whose distance has always been too small to make out their separate destinies yet too broad to facilitate their joining. It follows the need to reflect upon the infrastructure of the entire surrounding area which, while proposing a study on the themes of accessibility and crossing, also outlines a strategy running on harbours and airports as gateways to the entire area to scale with nature and the size of its traffic
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
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
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

The album of Mattia De Rossi’s drawings. Projects for the Galleria Colonna ai Santi Apostoli
Full text linkThe study proposed here on Mattia De Rossi, a pupil of Gian Lorenzo Bernini and his most trusted collaborator, is part of an investigation that the author is doing on the figure of the architect, making use of an obvious investigative tool: his drawings.
In particular, the exceptional discovery of a bound volume of about 200 drawings of Mattia is a resource of great effectiveness for the study of his professional figure. Among the sheets of the collection, those relating to the construction site of the Galleria Colonna in the eponymous palace in Piazza SS. Apostoli in Rome, are presented.
These drawings explain the important contribution of Mattia and the creative process that led him to the definitive version of the central hall of the gallery. The drawings are also the only graphic documents related to the project of the Galleria Colonna, now only partially known through hypothetical reconstructions.
The case of the Palazzo Colonna is similar to other projects included in the volume, which enlighten us on De Rossi's career, and which explain his position in several important Roman buildings of the second half of seventeenth centur
