L'invenzione del Mediterraneo. erritori e culture nelle reti di un mare alla ricerca di un progetto comune
No full textCe travail a été présenté au séminaire international « Mediterraneo. Scuola e incontro fra culture [Méditerranée. Ecole et rencontre de cultures], organisé par l’Istituto tecnico di Portici sous l’égide du Conseil de l‘Europe (Ercolano / Naples 10-13 novembre 2003).
L’idée de la Méditerranée ne « va pas de soi »... Si cette mer existe, bien sûr, et s’il existe une réalité physico-géographique, son unité, son identification en tant que région géographique et aire culturelle apparemment définie, relève d’une élaboration idéologique. En d’autres mots, cet article insiste sur l’idée que la Méditerranée n’a pas été toujours pensée comme un ensemble, et que les représentations dont elle est l’objet évoluent dans le temps et même dans les territoires qu’y se réfèrent. Ce travail se veut une contribution visant à comprendre le processus de construction la Méditerranée en tant qu’objet géographique, tout en proposant, dans l’esprit du Séminaire, des pistes méthodologiques inhérentes aux façons d’enseigner le monde Méditerranéen
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
Conservation Law Analysis in Numerical Schema for a Tumor Angiogenesis PDE System
No full textTumor angiogenesis, the formation of new blood vessels from pre-existing vasculature, is a crucial process in cancer growth and metastasis. Mathematical modeling through partial differential equations helps to understand this complex biological phenomenon. Here, we provide a conservation properties analysis in a tumor angiogenesis model describing the evolution of endothelial cells, proteases, inhibitors, and extracellular matrix. The adopted approach introduces a numerical framework that combines spatial and time discretization techniques. Here, we focus on maintaining solution accuracy while preserving physical quantities during the simulation process. The method achieved second-order accuracy in both space and time discretizations, with conservation errors showing consistent convergence as the mesh was refined. The numerical schema demonstrates stable wave propagation patterns, in agreement with experimental observations. Numerical experiments validate the approach and demonstrate its reliability for long-term angiogenesis simulations
Il Cross Border Shopping al confine italo-sloveno. Una ricerca empirica nella provincia di Trieste
No full textIl commercio transfrontaliero, più noto come cross-border shopping, ha origine quando acquirenti di un paese oltrepassano la frontiera per effettuare acquisti nei paesi contigui. Il fenomeno si manifesta in modo diverso nelle varie aree di confine, in quanto molteplici sono i fattori che lo possono influenzare. Per quanto riguarda il confine italo-sloveno, la consistenza del commercio transfrontaliero giustifica pienamente uno studio specifico. Dal punto di vista metodologico, il lavoro è stato diviso in due parti: la prima di carattere teorico e di raccolta dei dati secondari; la seconda di carattere empirico, con ricerche di tipo qualitativo e quantitativo
Cross border shopping. Il quadro di riferimento
No full textIl commercio transfrontaliero, noto a livello internazionale come cross border shopping, al confine italiano nordorientale con la Slovenia, ha sempre inciso in modo significativo sul tessuto economico locale. Da tempo era quindi sentita l'esigenza, sia da parte degli operatori commerciali che delle istituzioni, di effettuare una ricerca sul campo. Da queste premesse ha avuto origine il presente studio: l'area di confine italo-slovena presenta infatti delle peculiarità e dei processi evolutivi che vanno analilzzati anche al fine di supportare gli operatori locali nella ricerca di vantaggi competiitivi differenziali e nel miglioramento delle strategie di marketing
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
