Prodromi di un’Eresia. Note metafisiche e temi iconografici per un’archeologia dei cieli mesopotamici, in Galluzzi, P. (ed.), Galileo. Immagini dell'Universo dall'antichità al telescopio, Firenze 2009, pp. 54-59.
No full textL’osservazione empirica dei cieli fu una conquista relativamente recente delle scienze moderne, ma di cruciale importanza, poiché – come noto – sostituì alla centralità teorica e figurata della Terra la multidimensionalità
dell’universo. Nello specifico poi delle percezioni, e per introdurre la nostra esplorazione dei cieli nella terra tra i due
fiumi, è bene ricordare che “cosmo” è un termine greco, ma non sappiamo con esattezza quando e dove assunse il valore di ordine, né tantomeno quello di Ordine Celeste. Questo breve saggio intende dunque
ripercorre, ex oriente, il tratto più antico di quella tradizione che ha connesso Babilonia a Gerusalemme, due epicentri
dell’astronomia e dell’ideologia previsionale vicino-orientali che certo non furono ignoti all’orbita alessandrina. D’altronde, il cielo nostrum, antico e vicinoorientale, evoca anche le atmosfere notturne delle Mille e una notte, ma per convenzione, tradizione e fatale assenza di altre informazioni, una delle prime poetiche separazioni del cielo
dalla terra può essere retrodatata – con una buona approssimazione – alla stesura del Poema della Creazione, l’Enuma Elish, redatto poi all’epoca di Nabucodonosor I di Babilonia (1124-1103 a.C.). Il progetto avrebbe previsto
la produzione di un’umanità al servizio degli dei, e – secondo miti ancor più antichi – l’edificazione dell’Esaghila, dimora degli Anunnaki, le seicento divinità del cielo e della terra. In questa divisione, nella separazione delle due unità, prende dunque vita l’ordine celeste e il suo doppio, quello umano poggiato su un disco piatto, galleggiante sull’oceano primordiale, e finito solo dal limite che ne segnerebbero gli astri.Empirical observation of the heavens was a relatively recent achievement of modern science, but of crucial importance, since - as noted - substituting the theoretical centrality of the Earth and figured the multidimensionalitàdell'universo. Specifically then perceptions, and to introduce our exploration of the heavens in the land between the duefiumi, remember that "cosmos" is a greek word, but we do not know exactly when and where he assumed the value of your order, nor to Celestial Order. This short essay will dunqueripercorre, former East, the oldest part of the tradition that has connected Babylon to Jerusalem two epicentridell'astronomia and ideology forecast near-eastern and some were not unknown to the orbit of Alexandria. On the other hand, the sky nostrum, ancient and vicinoorientale, also evokes the nocturnal atmosphere of the Arabian Nights, but by convention, tradition and fatal absence of other information, one of the first poetic separations cielodalla land can be backdated - with a good approximation - the drafting of the Poem of Creation, the Enuma Elish, then drawn at the time of Nebuchadnezzar I of Babylon (1124-1103 BC). The project would previstola production of a humanity in the service of the gods, and - according to ancient myths even more - the building dell'Esaghila, home of the Anunnaki, the six hundred gods of heaven and earth. In this division, the separation of the two units, thus takes the order of celestial life and his double, the human resting on a flat disk floating in the primordial ocean, and just finished from the edge that it would mark the stars
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
MR brain imaging of fucosidosis type I
No full textSUMMARY: Fucosidosis is a rare autosomal recessive lysosomal storage disease with the main clinical findings of progressive neuromotor deterioration, seizures, coarse facial features, dysostosis multiplex, angiokeratoma corporis diffusum, visceromegaly, recurrent respiratory infections, and growth retardation. Fucosidosis type I rapidly evolves toward a progressive neurologic deterioration and death. We report MR imaging findings of the brain of three patients with fucosidosis type I, including previously unreported findings, to expand the knowledge of the neuroradiologic spectrum of the disease
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
