Living Room. La percezione dello spazio domestico al tempo della pandemia nell’opera di 9 artisti contemporanei / The Perception of Domestic Space in a Time of Pandemic in the works by 9 contemporary artists
No full textThe experience of the previous lockdown and the ongoing social distancing have marked a clear boundary between the “before” and “after” the pandemic, creating conditions that led us to think differently on many aspects of our life from both an individual and a collective point of view. These aspects, inevitably, have also changed our perception of the domestic space. Conceived as a sort of contemporary Wunderkammer, "Living Room" is a chamber of wonders where the concept of domestic space, physical and mental, plays an essential role. This idea has been evoked, displayed and exhibited according to its possible “atmospheres” through the interplay of the works by the 9 artists: Cesare Bignotti, Eleonora Chiesa, Clorophilla, Isabelle Fordin, Loredana Galante, Monika Grycko, Fabio Moro, Matteo Pulvirenti, Dana Wyse
Grafica pubblicitaria per Sanremo e la Riviera: alle origini del turismo in Liguria

Passaggi dentro la reggia: ragioni e percorso della mostra
No full textTesto di accompagnamento al percorso espositivo della mostra "We Linked Passages. Maestri del Novecento dalla collezioni private genovesi": la mostra presenta all’interno delle sale di Palazzo Reale diciannove lavori di grandi maestri della seconda metà del Novecento, italiani e stranieri, inseriti all’interno del sistema della dimora storica.
Il titolo, preso dall’ultima opera del percorso espositivo, del pittore e musicista americano Ben Patterson, sottolinea la volontà di collegare mondi solo in apparenza distanti: quello dell’arte antica a quello dell’arte contemporanea; il complesso di una residenza aristocratica all’universo delle poetiche e dei linguaggi dell’arte contemporanea; il patrimonio dei musei nazionali a quello delle raccolte private genovesi; il meglio dell’arte italiana al meglio dell’arte internazionale.
Le opere, prestate da generosi e appassionati collezionisti, solitamente invisibili al pubblico, sono state scelte per creare dialoghi, reazioni e contaminazioni per contrasto o per assonanza
Ru3(CO)12 in Acidic Media. Intermediates of the Acid-Cocatalyzed Water-Gas Shift Reaction (WGSR)
No full textThe elucidation of the WGSR promoted by ruthenium carbonyls in acidic media started with the detection of the Ru(0), Ru(I), and Ru(II) intermediate complexes, namely Ru-3(CO)(12), Ru-2[mu-eta(2)-OC(CF3)O](2)(CO)(6), and fac-[Ru(CF3COO)(3)(CO)(3)](-), which accumulate when CF3COOH is employed as an acid cocatalyst. Under catalytic conditions, the three were found to interconvert through elementary steps which produce CO2 and H-2. In fact, Ru(0) is oxidized by H+ to Ru(I) and half the hydrogen of the catalytic cycle is supplied by this reaction. On the other hand, Ru(I) disproportionates to Ru(0) and Ru(II), and this latter species undergoes nucleophilic attack by H2O. The decomposition of the metallacarboxylic acid intermediate gives back Ru(I), while H-2 and CO2 are produced in a 1/2 molar ratio. The two alternating pathways for dihydrogen formation, namely Ru(0) oxidation by H+ and the decomposition of a metallacarboxylic acid intermediate, involve H-2 reductive elimination from the same RuHCF3COO(CO)(2)L(2) intermediate (L = H2O, ethers). These findings define an acid-cocatalyzed WGSR whose distinctive features are (i) the intervention of a disproportionation reaction to generate a Ru(II) electron poor complex, whose CO ligands can undergo nucleophilic attack by water, (ii) the generation of the hydride intermediate for dihydrogen production through two distinct reaction patways, and (iii) the reductive elimination of H-2 from the hydride intermediate without involving H+ from the medium
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
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
