"Madri e Matrigne: la metropoli vittoriana di Peter Carey"
No full textAlla luce del più recente dibattito sulla rappresentazione dello spazio urbano nella letteratura postcoloniale, questo saggio analizza due romanzi: Jack Maggs e Oscar and Lucinda dell'australiano Peter Carey. La rappresentazione della Londra vittoriana nei due testi offre una importante esemplificazione di una 'metropoli' intesa etimologicmante come 'terra madre', ma anche, attraverso una sovversione parodica, come 'matrigna' e ostile, riproponendo così, in una prospettiva postcoloniale, il problema della identità e della appartenenza
L'innovazione di prodotto per la transizione ecologica: Il riciclo del laterizio e del vetro
Full text linkIn the thematic environment of conscious use and material resource recycling, the Department of Architecture of the Roma Tre University is currently conducting a research line focused on environmental product innovation. This line consists of two application studies involving manufacturing companies in the construction sector. Both types of research address the issue of additives in the mix design of bricks and concrete, respectively, to achieve better-performing products. The results led to the prototyping of two products: a brick, made from waste replacing a fraction of clay with a mixture of bentonite sludge and metal residues, and a concrete screed mix, made from construction and demolition glass waste replacing natural aggregates
Londra 1851. Trasparenze e ombre del Crystal Palace in Mayhew e Dickens
No full textNel saggio ci si occupa dell’anno 1851 e della realizzazione del Crystal Palace e della Great Exhibition voluta quale segno ‘visivo’ eccellente della grandezza dell’Impero britannico nel suo farsi e della centralità occupata nel mondo dalla città di Londra. Fortemente voluta dalla regina Vittoria e soprattutto da suo marito Alberto, la Great Exhibition ebbe molti sostenitori ma anche detrattori, i quali molto ironizzarono l’avvenimento sulle pagine del Punch. In realtà, la finalità di tale esposizione universale fu quella di obbligare i visitatori stranieri così come i sudditi di sua maestà, ma in concreto doveva servire a mascherare con le luci del vetro del Palace ideato da Paxton, le forti contraddizioni sociali, politiche e d economiche di un momento storico cruciale che vedeva il passaggio dalla prima alla seconda fase della Rivoluzione Industriale. Sotto quella ‘big glass bubble’ (Carlyle) si incontrarono civiltà e popoli diversi azzerando per un periodo limitato e solo i quello spazio, le enormi differenze tra barbari e civilizzati. Forte fu l’impatto visivo di tanto vetro da divenire oggetto privilegiato in alcuni romanzi: l’analisi prosegue, infatti, con lo studio di Bleak House di Dickens e il meno noto ma non meno significativo 1851 The Adventure of Mr and Mrs Sandboys and Family who Came up to London to Enjoy Themselves, and to See the Great Exhibition di Henry Mayhew, accompagnato dalle incisione di George Cruikshank
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

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
