THE MATHEMATICAL TEACHING OF DE GIORGI AND ITS DESIGN REALITY
No full textEnnio De Giorgi was one of the greatest Italian mathematicians of the twentieth
century. Born in Lecce on February 8, 1928 and died prematurely in Pisa on October 25,
1996, he carried out his activity at the Scuola Normale Superiore of Pisa from 1959 to 1996.
The IPSAPA conference to which this book is dedicated was the first that took place after
twenty years of his death. The President, former pupil and assistant of his, therefore, decided
to remind him so that the relevance for the world of applications of his methods in research
and teaching might clearly appear. To illustrate these less publicized aspects, still of great
importance, some geometric themes useful in cartographic and design disciplines were
chosen. Above all his famous regularity theorem is interpreted in its urbanistic meaning. It is
actually meaningful both in planning for the future and in historical analysis of urban
evolution

No full textTHE INTERTWINED THREADS: CARDS, FRAGMENTS, MEMORIES
No full textThe note is mainly based on the structural bonds that connect the landscape-cultural mosaic. Sometimes there are clear and well-coordinated links, sometimes they are instead fragments of the past or vague intuitions for the future that must be replaced in a coherent framework. By transferring what was affirmed by De Mauro (1990) we can imagine a vague and imprecise conceptual framework where "we speak ill and we understand each other badly", but where interaction and negotiation allow us to refine a possible understanding. The palimpsest is one of the tools that allow time travel, while protocols are those that reduce the likelihood of false interpretations, even if they limit the fantasy of artistic perception. The conclusion recalls the splendid synthesis of the changing fate of the fragments of spiritual and material life that was given by Calvino in one of his invisible cities. Clarice, a city that alternates splendor and misery, succeeds in regenerating and reusing all the material signs of its past, in improper and paradoxical ways, because in the end the order of succession of the eras has been forgotten
FROM ORDER TO ERRATICITY
No full textAccording to the laws of physics, order has a cost, in terms of the creation of some form of disorder somewhere else, as the entropy states. The paper considers examples taken from everyday’s life, and their empirical solutions. There exist exact methods for creating and maintaining order, found at the origin of artificial intelligence by Simon, referred to as linked lists. Unlike what is generally supposed erraticity is not a pure randomness problem, but rather must take into account actual bifurcations, possibly not reversible. Since we are interested also on the cultural side of mosaic, it is correct to start from persons whose life has been important, but erratic, with relevant turns in their activity, or in their long time fortune. The examples we give, should suggest the reader to look for other examples according to his own inspiration. An exercise, that is only sketched in the paper, is to look for the turning points that we can find in the history of landscape or in the history of towns. When does erraticity arise, how long does it remain undefined and subject to randomness, when becomes irreversible
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
