Scrittori di libri nell’editoria del Novecento
Get PDFIl saggio esamina il ruolo dell’autore nell’editoria novecentesca, focalizzandosi su come molti scrittori non si siano limitati a comporre testi, ma abbiano anche partecipato attivamente alla progettazione materiale e editoriale dei propri libri. A partire dalle riflessioni di studiosi come Petrucci, Cadioli e Ferretti, è messo in luce quanto la figura del “letterato-editore” sia centrale nel Novecento italiano, e se ne seguono le evoluzioni attraverso casi emblematici come quello di Italo Calvino. L’intervento analizza le implicazioni filologiche e critiche della collaborazione autoriale alle scelte editoriali (dalla disposizione dei testi alle strutture peritestuali), sottolineando la rilevanza delle “variazioni d’autore” apportate agli indici delle diverse edizioni della stessa opera, ciascuna potenzialmente portatrice di un atto creativo a tutti gli effetti. L’intreccio tra le attività degli scrittori e quelle della redazione di una casa editrice viene letto come spazio privilegiato per comprendere la modernità letteraria, le trasformazioni dell’autorialità e il rapporto tra produzione editoriale e identità letteraria.The essay examines the role of the author in twentieth-century publishing, focusing on how many writers not only composed texts but also actively participated in the material and editorial design of their own books. Drawing on the reflections of scholars such as Petrucci, Cadioli, and Ferretti, the study highlights the centrality of the "writer-editor" figure in twentieth-century Italian literature, tracing its evolution through emblematic cases such as that of Italo Calvino. The article analyzes the philological and critical implications of authorial involvement in editorial decisions—from text arrangement to peritextual structures—emphasizing the significance of “authorial variations” introduced in the tables of contents across different editions of the same work, each potentially constituting a fully-fledged creative act. The intersection between the work of writers and that of editorial teams is interpreted as a privileged space for understanding literary modernity, transformations in the notion of authorship, and the relationship between editorial production and literary identity
Comparative analysis of concentrating solar power and photovoltaic technologies: Technical and environmental evaluations
No full textSolar energy is an important alternative energy source to fossil fuels and theoretically the most available energy source on the earth. Solar energy can be converted into electric energy by using two different processes: by means of thermodynamic cycles and the photovoltaic conversion.
Solar thermal technologies, sometimes called thermodynamic solar technologies, operating at medium (about 500 C) and high temperatures (about 1000 C), have recently attracted a renewed interest and have become one of the most promising alternatives in the field of solar energy utilization.
Photovoltaic conversion is very interesting, although still quite expensive, because of the absence of moving components and the reduced operating and management costs.
The main objectives of the present work are:
- to carry out comparative technical evaluations on the amount of electricity produced by two hypothetical plants, located on the same site, for which a preliminary design was made: a solar thermal power plant with parabolic trough collectors and a photovoltaic plant with a single-axis tracking system;
- to carry out a comparative analysis of the environmental impact derived from the processes of electricity generation during the whole life cycle of the two hypothetical power plants.
First a technical comparison between the two plants was made assuming that they have the same
nominal electric power and then the same total covered surface.
The methodology chosen to evaluate the environmental impact associated with the power plants is the Life Cycle Assessment (LCA). It allows to analyze all the phases of the life cycle of the plants, from the extraction of raw materials until their disposal, following the ‘‘from cradle to grave’’ perspective. The environmental impact of the two power plants was simulated by using the software SimaPro 7.1, elaborated by PRé Consultants and using the Eco-Indicator 99 methodology.
Finally, the results of the analysis of the environmental impact are used to calculate the following parameters associated to the power plants: EPBT (Energy Pay-Back Time), CO2 emissions and GWP100
(Global Warming Potential over a 100 year time horizon)
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
