L’ecosostenibile è verde?
No full textOggi la sostenibilità non è più solo un requisito riferibile alla materia di cui un prodotto è fatto, e le cose sono molto più complesse tanto che un prodotto green non è più indiscutibilmente verde: un colore da solo non riesce a rappresentare un concetto così articolato. Ecologia e sostenibilità so-no infatti divenuti concetti multiformi, densi e fortemente carichi di molteplici significati, arrivando ad investire fattori molto distanti tra loro come il processo produttivo, il consumo di energia e di risorse naturali, ma anche il livello culturale e ciò ha consentito di fatto di comunicare questo con-cetto in molti modi tra cui la strategia di marketing, la comunicazione aziendale, la filosofia di brand, ecc.
Ma il colore, soprattutto se verde, è capace ancora di indicare eticità, naturalità, salubrità e be-nessere, in alcuni settori come ad esempio l’agroalimentare biologico la cui “immagine” è ancora fortemente riferita al colore verde, associato a genuinità e natura. Così, al colore delle spighe del grano si preferisce in questi casi quello verde della clorofilla, anche se sempre più si sceglie di raf-forzare il messaggio con simboli che rimandano a certificazioni di qualità (iso, CE, ecc.) o a de-nominazioni di categorie (dop, dco, dopg, ecc).
E sempre in verde sono le energie rinnovabili, il cibo a chilometro zero, le vacanze, l'innovazione e le migliori tecnologie.
Dunque, se è vero che abbiamo palette infinite per rappresentare l’ecologia, molto spesso ci mancano ancora le categorie di pensiero per moltiplicarla
Ecology and colour – the emerging design perspective
No full textUntil some time ago it was possible to identify a sort of popular correspondence between ecology and colour. In fact, sustainability of a product could be expressed with the green colour. Many products
were characterised by a blend of colours: the memory of the various materials was combined in the new product; for this reason they used to appear varied and personalised, being clearly recycled. In
other cases the material, either semifinished or crafted, could exhibit unambiguous signs or symbols related to nature. Among the examples is the laminate whose weave incorporates natural elements in
transparency, although this does not grant real sustainability. Our question is whether and how color can still be considered an ecological metaphor, or whether colour is being used in different ways due
to changes occurring in the wider issues of sustainability, connected with environmental policy, productive processes, sensorial culture. Ecology is an increasingly complex concept. It can be
expressed through various features; since it is free from stereotypes and commonplaces, it can be represented by various colours. Colour is an essential cognitive driver (function), poetic syntax (decoration), historical and cultural subject (communication); we intend to verify whether, in the design perspective, it still proves consistent with its conceptual framework: bio-diversity, decomposability, handicraftness, quality of life, sobriety, smoothness, frailty, mimesis, lightness, edibility, ...
technology, expressive freedom, playfulness; within a continuous dialogue with matter, object, space,
memory. In such a framework we will address the concept of sustainable sensoriality. Colours can represent a powerful ecological metaphor in some design scenarios
Ecology of Colour: From the supremacy of green colour to new scenario between colour and ecology
No full textColour in sustainability is green. The green colours is still able to show ethical, natural, healthy and well-being orientations in areas such as the biological agroindustrial sector whose ‘image’ is still related to the green colour, associated to authenticity and nature. In such a way the chlorophyll green is preferred to the wheat ear yellow, although the message is strengthened with symbols showing quality certifications (ISO, CE, etc.) or with category labels (DOP, DCO, DOPG, etc.). Green is always the colour of renewable energies, zero kilometre food, holidays, innovation and smart technologies. Therefore, it is true that we can represent ecology with infinite colour scales, but very often we still lack the thought categories allowing us to multiply it.

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
