Fotografia, patrimonio, paesaggio. Tra inventario e raffronto
No full textLa prima immagine fotografica della storia è una fotografia di paesaggio. Si tratta di una ‘eliografia’ su lastra di peltro e bitume, ottenuta nel 1826 o 1827 da Joseph-Nicéphore Niépce, un gentiluomo francese di provincia con la passione per la tecnica e le invenzioni. Quasi tutti i manuali di storia della fotografia pubblicati dopo il 1952, anno del suo ritrovamento, si aprono con questa veduta dalla casa di famiglia a Saint-Loup-de Varennes, con il titolo Point de vue. La paternità di questa immagine è stata a lungo in discussione, perché i tentativi di riprodurla fallivano davanti all’impossibilità di trovare un punto di vista che le corrispondesse da una delle finestre della casa. Si scoprì poi che la finestra era stata spostata durante una ristrutturazione e l’immagine corrisponde effettivamente alla vista che si godeva dalla precedente apertura. Per questo, oggi è impossibile effettuare uno scatto di raffronto. Secondo Susan Sontag: “Le fotografie sono preziose perché danno informa-zioni. Dicono cosa c’è, fanno un inventario. Per le spie, i meteorologi, i conduttori di inchieste, gli archeologi e gli altri informatori professionisti, esse hanno un valore incalcolabile” (Sontag, 2004:20-21). Il loro valore do-cumentario si basa sul fatto che le immagini possano essere conservate e osservate in un momento diverso da quello in cui sono state scattate (Brunetta, Minici Zotti, 2014), confrontando lo stato in cui il soggetto si trovava quando fu immortalato, quello attuale, e uno o più stati futuri. A partire dal celebre prologo di Point de vue, le pagine seguenti propongono una riflessione sulla fotografia come strumento di documentazione, il suo rapporto con la memoria e la pratica del foto-raffronto
BEST BEFORE? ADVANCED GEOMATICS FOR PRESERVATION AND PRESERVATION OF ADVANCED GEOMATICS
Full text linkThis discussion paper deals with the task of preserving past geometrical surveys and keeping them in use. The continuous advancement in technology caused a quick ageing of both survey techniques and their outcomes. This may result into a predetermined expiration date after which they risk losing their quality and usefulness (hence the title «Best Before»). Facing this risk, this paper focuses on the unceasing relevance of past surveys both as a legacy in the history of technique and as a fundamental source of information on heritage buildings, and thus a support to the preservation activity. The present paper offers an overview of the most recent attempts of preserving and keeping in use the paper surveys of the past
Il consumo di suolo nella montagna lombarda. Un confronto tra piano e progetto urbano nel Novecento
Full text linkIl testo confronta due forme di pianificazione che hanno governato lo sviluppo del
territorio e regolato il consumo del suolo montano nel corso del Novecento: il progetto
urbano degli anni Trenta-Quaranta e la pianificazione concordata degli anni Sessanta-
Duemila. L’analisi si concentra sul caso di Sondalo in Alta Valtellina, un centro abitato
d’impronta medievale dove, tra il 1932 e il 1940, fu costruito un Villaggio Sanatoriale di
oltre 600.000 mc. Questo grandioso esempio di urbanistica modernista fu progettato per
iniziativa statale nella forma di una megastruttura. Dopo la guerra, l’abitato di Sondalo è
cresciuto grazie allo sviluppo economico e demografico propiziato dal grande sanatorio,
secondo le indicazioni del Piano Regolatore e degli strumenti di pianificazione e
programmazione sovralocali (PTCP, PTA). Gli autori propongono un confronto sugli esiti
che queste due forme di urbanizzazione hanno prodotto sullo sviluppo territoriale e sul
consumo di suolo in questo tratto di montagna lombarda
GIS OR BIM? A COMPARISON APPLIED TO THE CONSERVATION MANAGEMENT PLAN OF A 20th CENTURY ARCHITECTURAL HERITAGE
Full text linkThis paper discusses the impact of the advanced systems of architectural survey and modelling to the research on the Conservation Management Plan (CMP) for architectural heritage, particularly when such a tool is applied to the 20th century architectural heritage. The authors focus on a comparison between the Building Information Modelling (BIM) technology and the Geographic Information Systems (GIS). The Conservation Management Plan for the National Art Schools of Havana in Cuba is used as case study. Given the plurality of buildings and various levels of interest in such a context, conservation and management needs, the need to share the results with non-specialized stakeholders, the need to combine different scales of analysis and different typologies of materials, the results point out the advantages of a GIS platform. The conclusions open to further possibilities of integrating GIS and BIM to the specific task of effectively conserving and managing the 20th century architectural heritage
ADVANCED GEOMATICS AND CONSERVATION MANAGEMENT PLAN FOR PRESERVING 20th CENTURY ARCHITECTURAL HERITAGE
Full text linkThis paper discusses the relationship between advanced geomatics and Conservation Management Plan (CMP), by deepening the case of a CMP dedicated to the conservation of the 20th century architectural heritage. A number of issues have already been discussed on how the advanced survey techniques contribute to the conservation field for the last decades (e.g. Laser Scanner, HDR, GIS, intelligence vs. abundance, B.I.M, VT/IM etc.). The authors analyse pros and cons of each technique with respect to the main purposes of a CMP: 1.knowledge, 2.value assessment, 3.data sharing and dissemination of results, 4.support for conservation and restoration activities, 5.support for the planned conservation of buildings / facility management over time. With respect to the research on the CMP for the National Art Schools of Havana, the conclusions focus on the need to share results to non-specialist stakeholders, and on the possibility to combine different scales of analysis and a plurality of buildings with various levels of interest and conservation needs

Assessment of climate-driven flood risk and adaptation supporting the conservation management plan of a heritage site. The national art schools of Cuba
Full text linkThis work illustrates the contribution of flood risk assessment and adaptation to set up a conservation management plan for a masterpiece of 20th-century architecture. Case study is the iconic complex, internationally known as the National Art Schools of Cuba. It consists of five buildings built in the early 1960s within a park of Habana next to the Caribbean Sea. The path of the river (Rio Quibù) crossing the estate was modified to fit the landscape design. The complex has then been exposed to the risk of flooding. The School of Ballet, located in a narrow meander of the river, slightly upstream of a bridge and partially obstructing the flow, is particularly subject to frequent flash floods from the Rio Quibù, and it needs urgent restoration. Keeping ISA Modern is a project aimed at preserving the Schools complex. Based upon in situ surveys on the Rio Quibù and local area measurements during 2019, numerical modelling, and previous work by the Cuban National Institute of Hydraulic Resources, we pursued a flood risk analysis for the area, and a preliminary analysis of available risk reduction strategies. Using HEC-RAS 2D software for hydraulic modelling, we evaluated the flooded area and the hydraulic conditions (flow depth, velocity) for floods with given return periods. Our results show that SB is a building most subject to flooding, with high levels of risk. Defense strategies as designed by Cuban authorities may include a (new) wall around the School of Ballet and widening of the river channel, with high impact and cost, although not definitive. Temporary, light, permanent, and low cost/impact flood proofing structures may be used with similar effectiveness. We demonstrate that relatively little expensive hydraulic investigation may aid flood modelling and risk assessment in support of conservation projects for historically valuable sites. This may support brainstorming and the selection of (low to high cost) adaptation and risk reduction measures in the coastal areas of Cuba in response to ever increasing extreme storms and sea level rise controlling flood dynamics under transient climate change
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
