Municipal civil protection plans: Origins, development,and new actions of land-use planning (part II)
No full textLa normativa degli ultimi venti anni dà ai piani
comunali di protezione civile un valore crescente tra
le attività di pianificazione del territorio, ma i relativi
caratteri specifici stentano ad affermarsi tra gli addetti.
Questo contributo, nella sua prima parte (pubblicata
sul n. 95), ha restituito il percorso, dalla genesi a oggi,
della pianificazione di protezione civile nel nostro paese,
ricostruendone l’evoluzione tra norme e indirizzi. L’esito
culminato nel D.Lgs. 1/2018 definisce i ruoli di sindaci,
strutture amministrative comunali, regioni, volontariato
e prefetture. Questa seconda parte espone il nuovo ruolo
del piano di protezione civile comunale nel quadro
del ‘Sendai Framework for Disaster Risk Reduction’ e
offre spunti per la cruciale direttiva nazionale sulla
pianificazione di protezione civile in fase di stesura.

However, its peculiar characteristics are not always mastered by professionals. In its first part (see 'Territorio' no. 95), this article presented the path, from genesis to current references, of civil protection planning in Italy, reconstructing the mutual evolution of regulatory and governance actions. The result defines the roles of mayors, municipal structures, regions, volunteers, and prefectures after the Legislative Decree 1/2018. In this article's second part, the role of municipal civil protection plan in the framework of Sendai Framework for Disaster Risk Reduction is described. Lastly, themes to be considered for the next crucial national directive on civil protection planning are suggested
Testing the use of reimbursement data to obtain damage curves in urbanised areas: the case of the Piedmont flood on October 2000
No full textThis article analyses the assessment of economic damages in urbanised flooded areas by testing the use of reimbursement data to obtain damage curves. Data coming from field observation of the 2000 flood in Piedmont, Italy, are used and the influence of local features and topography, as well as urban patterns are studied. Our starting point is the assessment of individual flooded elements, whose damages result from slightly more than 7000 refund claims. Damage functions estimation is carried out by using water depth and flow velocities obtained by 2D inundation model. Results show the relationship of damage versus water depth and versus flow velocity are strongly nonlinear and urban patterns playing a major role in explaining the amount of damage under given conditions. Moreover, results provide useful information for future ex ante estimation of potential flood damages and rewarding risk reductions and management actions
An experience of urban transformation in multan-Pakistani punjab
No full textThis publication concerns studies, programmes and designs for the project Sustainable Social Economic and Environmental Revitalization in the historic core of Multan City in Pakistani Punjab developed by several Politecnico di Milano Departments and Fondazione Politecnico di Milano, an institution that cooperates with Politecnico di Milano in the research fields of architecture, engineering and industrial design. The activities are part of the Debt Swap Agreement signed in 2006 between the governments of Italy and Pakistan for development in the social sectors. Besides the extraordinarily valuable architecture of the Walled City of Multan and its dense and hard-working population, there is a physical and environmental condition that is extremely problematic and that may threaten the continuity of life in the historic part of a city, well known for being among the world’s most ancient settlements. The social and cultural interest and the academic challenge of a new opportunity to deal with great traditions pushed the researchers to face the urgency and delicacy of a very complex theme. After the analysis, the surveys and the proposals, the Politecnico group completed the first operational phase reorganizing one of the main City Gate Place, building a new open pavilion and restoring a huge public building and the Gate. The last activity, planned and not yet implemented, refers to the Sarafa Bazaar Project, an integrated system for the urban arrangement through infrastructures systems as sewerage, public lighting and shading, new paving and conservation of historic building’s façades
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
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
