I “graffi” della protesta Street art, barriere artificiali e forme di espressione del dissenso
No full textStreet art is any art – specifically visual art – developed in public
spaces. It can include traditional graffiti artwork, stencil, sculpture,
sticker art, street poster art, video projection, guerrilla art, flash mobbing, wheatpasting, etc. Typically, the term is used to refer to unsanctioned
or “prohibited” art, as opposed to institutional artistic initiatives. So, is
it possible to speak about street art as a form of protest art? If so, what
are the signs, texts, codes and practices through which graffiti, stencils
and other forms of street art can serve as means to express opposition
and dissent? The present paper aims at answering these questions at first
through a general historic introduction that will try to contextualize and
describe the street art phenomenon and its evolution over time, then
focusing on two specific case studies whose purpose is to investigate,
from a semiotic point of view, its role in the expression of dissent and
protest acts. Especially, we will deal with the use of graffiti, stencils
and posters as means of protest against two very known and discussed
examples of separation barrier
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
Subcutaneous immunoglobulin therapy for refractory skin thickening in rapidly progressive systemic sclerosis: A case report and literature review
Get PDFThe use of immunoglobulin is a therapeutic option with increasing evidence of efficacy for different rheumatologic autoimmune systemic diseases. Some studies concerning immunoglobulin use in systemic sclerosis have been published with encouraging results. We present the case of a young woman diagnosed with rapidly progressive diffuse cutaneous systemic sclerosis, refractory to therapy with methotrexate and rituximab, which presented a relevant skin improvement after one year of subcutaneous immunoglobulin (2 g/kg cumulative monthly dose, refracted in weekly administrations). Furthermore, a narrative literature review of the evidence for alternative treatments with a focus on immunoglobulin use for systemic sclerosis skin involvement was carried out
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
