Nuove forme dell’abitare / New Forms of Living Space. Letture e trascrizioni intorno alla Scuola di Architettura di Sarasota in Florida / Readings and Transcripts from Florida’s Sarasota School of Architecture
No full textNell’America degli anni ’50 una rivoluzione epocale segna il passaggio dalla modernità alla contemporaneità, avviando quel processo di post-modernità che ha attraversato la seconda metà del secolo scorso. I linguaggi architettonici di quegli anni, con particolare riferimento alla singolarità degli eventi del secondo dopoguerra ed alla modernizzazione e sviluppo degli stati del sud (California e Florida in primis), determinarono un mutamento sostanziale del quale ancora oggi riconosciamo i caratteri
principali negli esiti dell’architettura contemporanea realizzata fino alla fine del ‘900. Il tema di indagine scelto, parallelamente al percorso svolto all’interno del modulo di Composizione, è stato quello dell’Architettura Americana degli anni ‘50 e ’60 individuando nell’abitazione monofamiliare del dopoguerra (con particolare riferimento al fenomeno della Scuola di Sarasota in Florida) il riferimento più appropriato per la comprensione dell’approccio esigenziale-prestazionale e dell’utilizzo critico dei diversi sistemi costruttivi. Si sono scelte alcune residenze esemplificative del periodo storico e del contesto analizzato, rappresentative dei vari tipi costruttivi facilmente individuabili ed abbastanza diversi tra loro.La ricerca è stata condotta all’interno della cooperazione accademica tra l’Università della Florida (Scuola di Architettura di Gainesville) e l’Università degli Studi “Gabriele d’Annunzio” di Chieti-Pescara (Dipartimento di Architettura di Pescara), coordinata dalla prof.ssa Martha Kohen e dal prof. Carlo Pozzi.
L’Università della Florida ha messo a disposizione del prof. Domenico Potenza gli archivi delle Collezioni Speciali della George A. Smathers Libraries, attraverso la collaborazione di Martha Kohen (Coordinatrice della SOA-George Smathers Library, Special Collection), John Nemmers (Responsabile del Dipartimento delle Collezioni Speciali e dell’Area Studi della George A. SmathersLibraries) e Anzhelica Arbatskaia (M. Arch. della Scuola di Architettura di Gainesville)
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
Chemical composition and volatile constituents of Anthyllis barba-jovis
No full textSix flavonol glycosides were isolated and identified from the aerial parts of Anthyllis barba-jovis L. (Leguminosae), together with two coumarins and D-pinitol, a taxonomic marker of Leguminosae family. The structural elucidation of all compounds was based on their (1)H- and (13)C-NMR spectral data and bidimensional experiments. The total flavonoid content was also determined, according to the method described in the Italian pharmacopoeia. In order to complete the phytochemical investigation on A. barba-jovis, the essential oils from flowers and seeds were obtained by hydrodistillation and analysed by GC-MS; fresh flowers were analysed also directly by solid phase micro extraction (SPME)
A new Isoflavone from Genista corsica
No full textA new isoflavone (1), dihydroisoderrondiol [(3''S,4''R)-5,7,3'',4''- tetrahydroxy-2'',2''-dimethyl- 3'',4''dihydropyrano(5'',6'';3'',4'')isoflavone], was isolated from aerial parts of Genista corsica, together with 11 previously known compounds [daidzein, isoprunetin, isoderrone (2), ficuisoflavone (3), luteolin, luteolin 4'-O-β-glucoside, luteolin 7-O-β-glucoside, taxifolin, 5- methoxytaxifolin, sucrose, and D-pinitol]. The structure of 1 was elucidated by spectroscopic methods
