Recycling of non-metallic automotive shredder residues and coal fly-ash in cold-bonded aggregates for sustainable concrete
No full textIn order to achieve the relevant objectives of EC directive on end-of-life of vehicles (2000/53/CE), innovative solutions such as recycling automotive shredder residues are required. This paper deals with the design and characterization of concrete mixtures containing artificial aggregates obtained through the cold-bonding pelletization of non-metallic fraction of automotive shredder residues, commonly named car fluff. In this work, car fluff was pelletized with blended cementitious mixtures containing coal fly ash, another industrial by-product. Produced artificial aggregates were characterized by determining main environmental, physical and mechanical properties. Then, they were employed as lightweight aggregates for manufacture of sustainable concrete. Experimental results showed good mechanical properties of concrete containing these aggregates and leaching behaviour of hardened specimens confirmed the environmental effectiveness of the here studied car fluff recovery process
Fourth Industrial Revolution: Current Practices, Challenges, and Opportunities
No full textThe globalization and the competitiveness are forcing companies to rethink and to innovate their production processes following the so-called Industry 4.0 paradigm. It represents the integration of tools already used in the past (big data, cloud, robot, 3D printing, simulation, etc.) that are now connected into a global network by transmitting digital data. The implementation of this new paradigm represents a huge change for companies, which are faced with big investments. In order to benefit from the opportunities offered by the smart revolution, companies must have the prerequisites needed to withstand changes generated by “smart” system. In addition, new workers who face the world of work 4.0 must have new skills in automation, digitization, and information technology, without forgetting soft skills. This chapter aims to present the main good practices, challenges, and opportunities related to Industry 4.0 paradigm
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
Un progetto di trascrizione ed edizione digitale del codice Napoli, Biblioteca Nazionale, MS XIII.B.29
Full text linkL’articolo delinea gli obiettivi del progetto di trascrizione ed edizione
digitale del manoscritto Napoli, Biblioteca Nazionale, MS XIII.B.29. Il codice,
preziosissimo in quanto unico esempio di letteratura inglese tardomedievale conservato
in Italia, contiene romanzi cavallereschi e un poema agiografico che conobbero
ampia circolazione nell’Inghilterra del quattordicesimo e quindicesimo secolo,
oltre ad un ricettario medico finora poco conosciuto. A parte la sua rilevanza
filologica e letteraria (la maggior parte dei testimoni delle opere ivi contenute
si differenzia talvolta anche in modo marcato rispetto al resto delle rispettive
tradizioni testuali), la presenza di note in italiano e, soprattutto, di un’illustrazione
che testimonierebbe la sua possibile appartenenza a Tommaso Campanella pongono
il codice in una posizione di sicuro interesse storico e contestualizza in
modo peculiare la sua fruizione nell’ambiente culturale napoletano del sedicesimo
e diciassettesimo secolo. L’obiettivo principale del progetto consiste, dunque,
nel fornire uno strumento che permetta la più ampia fruizione e lo studio di un
manoscritto finora praticamente sconosciuto ma unico nel suo genere. Oltre a dettagliare le modalità di marcatura dei testi e di codifica degli elementi paratestuali,
si fornirà un piano preliminare di edizione, che verrà realizzato attraverso
l’interfaccia open source EVT
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
