Fare memoria durante una pandemia. Spazi e corpi simulati nelle pratiche di commemorazione durante il lockdown
Get PDFThis paper seeks to provide an investigation of the use of memory spaces and the practice of commemoration during the first wave of the Covid-19 pandemic, when people were forced to stay at home due to the lockdown. In particular, the authors point out how the reconfiguration of urban and domestic spaces, together with the increasing use of electronic and technological devices, has contributed to the production of new forms of memorial gathering, in which the collective subject has taken on different semiotic configurations each time. All the case studies in this article are related to a specific memorial day: the Italian commemoration of the 25th April, the date of Nazi-fascist liberation in 1945
Pre-emptive Memories. Anticipating narratives of Covid-19 in practices of commemoration
No full textThis article explores the narratives of the Covid-19 crisis in Italy, in the ways that they intersect with cultural memory processes. Moving from the hypotheses that the Covid-19 crisis, in Italy, has undergone two distinct narrative phases, we focus on the comparison between the forms taken, during the first lockdown, by an important (but also somehow divisive) memory ritual: the celebration of April 25 (the day that Italy was liberated from Nazi-Fascism) and the newly established commemorations of Covid-19 casualties. The aim is to observe the osmoses between two discursive domains (memory discourse vs. emergency discourse). To do so, we propose the concept of ‘pre-emptive memory’, which can be defined as an act of – unwitting – anticipation, pre-figuration and re-combination of the future cultural memory of an ongoing event in the present

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
Material model calibration by indentation, imprint mapping and inverse analysis
No full textThe identification of elastic–plastic material parameters by means of indentation tests and their finite element simulation is considered in this paper with the innovative provision of measuring the imprint geometry besides the indentation curves. The inverse analysis is carried out by a deterministic approach using conventional algorithms. The proposed methodology is validated using ‘‘pseudo-experimental’’ (computer generated) data with and without noise. Also friction between the indenter tool and the indented specimen is dealt with by inverse analysis and investigated through a parametric study. Sensitivity with respect to the sought parameters is examined for measurable quantities, including residual displacements on the specimen surface
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
