Studio del meccanismo di trasmissione del carico attraverso lo strato di cemento osseo (PMMA) di una artoprotesi totale d'anca
Dalla materia all'opera d'arte
Un viaggio attraverso 40000 anni di storia delle tecniche dell'arte e quindi attraverso i progressi della cultura umana in relazione all'evoluzione, sincronica, della cultura materiale, ergo il susseguirsi di quei fenomeni che in ogni epoca hanno interessato la vita pratica, sociale, religiosa, economica, produttiva del genere umano lungo il continuo divenire delle singole civiltà. L'opera d'arte, infatti, fin dal suo ingresso nella storia della cultura materiale umana nel Paleolitico, rappresenta una sintesi compiuta fra una visione, un pensiero, un'ispirazione intellettuale e la materia. Fra fantasticherie di ogni tipo ed elementi della natura, con le prime a dettare le disposizioni e le regole d'ingaggio ai secondi, alla loro trasformazione, possibile, però, solo mediante l'utilizzo delle mani in sinergia con strumenti a loro volta ideati e governati grazie all'intelletto, poiché solo così può essere possibile mutare un corpo in un altro, in ciò che l'idea ha enucleato in prima istanza
L'opera d'arte e il suo destino nella spirale: dalla materia all'immaterialità

Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
Unblackboxing Waste Management in Practice. A Set of Actions Enabling Circular City Making
This contribution intends to focus on the crisis of waste, particularly on the impact of post-use materials on practices of city making in the European context.
Waste is framed as an evident, perpetual and pervasive phenomenon that has affected both the geosphere and the organosphere. To deal with such an issue, it is needed to imagine new evolved forms of radical co-existence with discards, enabling circular practices.
The waste management infrastructural networks belong to an industrial system and their functioning corresponds to a black box model.
In the age of information and transparency, the notion of unblackboxing is here introduced with the aim to propose a set of actions for circular city making. Actions are based on three main considerations regarding the informational value of waste, the relationship between society and waste and, finally, the relationship between waste and city.
The actions will be described with examples, references and research-driven initiatives provided by the author
Appropriate Similarity Measures for Author Cocitation Analysis
We 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
We 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
