Applicazioni del telerilevamento termico da piattaforma satellitare ed aerea per aree urbane
No full textThe work deals with the employment of tools and techniques of thermal remote sensing from satellite and aerial platforms in urban areas. Thermography at city scale from satellite platforms is firstly discussed, with particular emphasis on the assessment of the Urban Heat Island phenomenon: different methods for the atmospheric corrections, the estimation of emissivity and the calculation of the Land Surface Temperature are dealt with. Afterwards an experimentation performed over the urban area of Bologna using ASTER images is described: the results show the presence of an Urban Heat Island in the study area, although its magnitude is difficult to estimate. The Central Europe Energycity Project - aimed at developing a GeoWeb Spatial Decision Support System as regards the reduction of energy consumption and greenhouse gas production in seven cities of Central Europe - is later introduced, describing the procedures for aerial and ground surveys and the processing workflow of digital datasets to create maps of roof surface temperature. Finally the experimentation performed on the city of Treviso using thermal aerial imagery acquired in winter 2010 is described, with the creation of a georeferenced mosaic of brightness temperature by means of both geometric and radiometric corrections. The results show that accurate surface temperature measurements may be obtained only by the implementation of different processing stages and after the exact assessment of emissivity values; moreover, knowing the spectral band of acquisition of the thermal sensor proved to be essential
Un journal « mal conçu et mal rédigé » : le Corriere d’Italia (1807-1808), ou comment relire les pratiques politiques des exilés italiens dans le Paris napoléonien
No full textLe 15 août 1807, un nouveau journal paraît à Paris : intitulé Corriere d’Italia, il est rédigé entièrement en italien et sortira tous les jours jusqu’au printemps suivant sous les presses de l’imprimeur Guitard. Sa ligne éditoriale lui vaut le soutien de l’Empereur, toujours intéressé à contrôler la diffusion des nouvelles au-delà des Alpes. C’est pourquoi il décrète un financement gouvernemental visant à permettre sa diffusion dans la Péninsule, et cela malgré l’opposition du vice-roi du royaume d’Italie Eugène de Beauharnais et du ministre des Affaires étrangères Ferdinando Marescalchi. Après une analyse des questions concernant la distribution du Corriere, cet article envisage d’enquêter sur sa ligne éditoriale, afin de comprendre les propos politiques qui soutiennent cette initiative. Par ce biais, nous nous proposons sinon de remettre en cause, du moins de nuancer, le clivage classique entre pratiques politiques et pratiques culturelles, ces dernières étant moins une simple alternative aux premiers qu’une façon de réarticuler, dans un autre contexte et sous d’autres formes, l’engagement des années précédentes.Il 15 agosto 1807, un nuovo giornale, il Corriere d’Italia, comincia le sue pubblicazioni a Parigi. Redatto esclusivamente in italiano, esso sarà pubblicato fino alla primavera successiva per i tipi dello stampatore francese Guitard. Grazie alla sua linea editoriale, il giornale conquista il sostegno dell’Imperatore, sempre attento al controllo della circolazione di notizie oltreconfine. Infatti, nonostante l’opposizione del Viceré del Regno d’Italia Eugenio di Beauharnais e del ministro degli Esteri Ferdinando Marescalchi, Napoleone ordina il suo finanziamento per facilitarne la diffusione nella penisola. Dopo un’analisi delle vicende inerenti la distribuzione del Corriere, l’articolo approfondisce le caratteristiche della sua linea editoriale per meglio comprendere i propositi che animarono una simile iniziativa. In tal modo, ci si propone di attenuare la dicotomia fra pratiche politiche e pratiche culturali e di considerare quest’ultime non come una semplice alternativa alle prime, ma come uno strumento per riarticolare, in un nuovo contesto e sotto altre forme, l’impegno degli anni precedenti.On 15 August 1807, in Paris a new newspaper appears, whose title is the Corriere d’Italia. Drafted in Italian, it would be published every day until the spring by the French printer Guitard. Thanks to its editorial-line, this newspaper wins the Emperor’s support, who is always interested in controlling the dissemination of news beyond the Alps. In fact, despite the opposition of the Viceroy of the Kingdom of Italy Eugène de Beauharnais and the Minister of Foreign Affairs Ferdinando Marescalchi, Napoleon decrees a government funding to allow facilitate its diffusion in Italy. After examination of the distribution of the Corriere, this paper deepens its editorial line in order to understand the political purposes supporting this initiative. In this way, the aim is to reduce the dichotomy between political practices and cultural practices: the latter is not a simple alternative to the first one, but a way of re-articulating, in another context and under other forms, the commitment of previous years

Il l’informe aussi que, dans le cadre de ce concours, d’autres mémoires avaient été envoyés. Au total, la commission chargée..
Comment (et pourquoi) parler de Révolution sous le Consulat : la Correspondance politique et confidentielle inédite de Louis XVI, par Helen Maria Williams
Full text linkInternational audienceIn 1803, the publication of the Correspondence of Louis XVI raises the attention of the Napoleonic censorship, preoccupied by the resurgence of the Bourbon party. However, the text has a different purpose, because the king’s letters are accompanied by some observations aiming to reveal his duplicitous conduct. The author, Helen Maria Williams, is an English woman who moved to France at the beginning of the Revolution. By writing about the king and the end of his power, she aims to analyse the first revolutionary period in order to defend the activities of her friends, the Girondins, and to propose a new institutional solution for Consular France. This editorial operation is clearly part of a real political project which aims to extend the political battle that had started in 1789.Further evidence of this plan is the fact that the publisher of her work is her partner, John Stone, himself a revolutionary man from England, and that they translate in English the Correspondence to distribute it in the United States.En 1803, la parution de la Correspondance de Louis XVI suscite l’attention de la censure napoléonienne, préoccupée par le resurgissement des partisans des Bourbons. Néanmoins, le texte s’avère avoir un but différent, car les lettres du roi sont accompagnées par des observations visant à faire connaître la duplicité de sa conduite. L’auteure, Helen Maria Williams, est une femme anglaise installée en France dès le début de la Révolution. En traitant du roi et de la fin de son pouvoir, elle vise à analyser la première période révolutionnaire pour défendre l’activité de ses amis girondins et pour proposer une nouvelle solution institutionnelle pour la France du Consulat. Il s’agit donc d’une opération éditoriale qui s’inscrit dans un projet politico-historiographique visant à prolonger la bataille politique commencée en 1789. Cela est d’ailleurs prouvé par le fait que l’éditeur est son compagnon, John Stone, lui aussi d’origine anglaise et ayant un passé révolutionnaire, et que les deux traduisent en anglais la Correspondance pour la faire paraître également aux États-Unis
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
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
Il reporting di sostenibilità nel settore pubblico
No full textIl presente studio si pone l’obiettivo di investigare il tema del sustainability reporting (SR) in ambito pubblico. A partire dalla proposta dell’International Public Sector Accounting Standards Board (IPSASB), finalizzata a rilasciare un framework di regole ad hoc per la realizzazione dei report sostenibilità, lo studio intende tracciare lo stato dell’arte sul tema nell’ottica di proporre una sintesi organica dello scenario in evoluzione individuando le tematiche e le principali indicazioni rese dai partecipanti alla consultazione IPSASB. Il metodo di ricerca è di tipo qualitativo con approccio interpretativo e documentale di fonti primarie e secondarie ( comment letters, siti web istituzionali, articoli scientifici, report settoriali/professionali). I risultati della ricerca sono orientati a tracciare lo stato dell’arte sul tema del sustainaibility reporting in ambito pubblico al fine di individuare gli ambiti e i principi rilevanti che dovranno essere le fondamenta di un futuro standard di sostenibilità per le organizzazioni pubbliche. L’originalità del lavoro di ricerca deriva dalla raccolta di evidenze teoriche sul tema di recente introduzione e in forte evoluzione
Le accademie venosine dei Piacevoli e dei Rinascenti. I testi, il canone e le politiche culturali
No full textThis essay examines several aspects hitherto little surveyed, relating to the two Academies born in Venosa between the sixteenth and seventeenth centuries: the Piacevoli and the Rinascenti. The analysis focuses mainly on the texts and lessons. For the former Academy, the “mythicized” cult of Horace is highlighted. Thanks to this, the local elites try to give
Venosa a symbolic centrality. For the latter Rinascenti, on the other hand, a greater modernistic trend can be identified and, moreover, the connection with the Accademia degli Oziosi in Naples. Finally, at the political level, my analysis emphasizes the difference between the two experiences. The Piacevoli had the local patriciate as their fulcrum, with the support of Scipione de’ Monti; for the Rinascenti, however, the political-cultural initiative of Prince Emanuele Gesualdo was decisive
