Conoscenza e gestione dei rischi tra frammentazione e settorialità. Il caso Napoli.
No full textLa molteplicità dei rischi che interessano il nostro Paese e la fragilità dei sistemi urbani e territoriali esposti richiedono un sostanziale ripensamento degli approcci e degli strumenti finora utilizzati per conoscere, prevenire e mitigare i rischi. Il prevalere di logiche emergenziali, l’elevata frammentazione delle conoscenze, la segmentazione delle competenze e la settorialità degli strumenti hanno, infatti, limitato l’“utilizzabilità” delle conoscenze disponibili nei processi decisionali orientati al governo del territorio e affidato la gestione dei rischi ad ambiti prevalentemente “tecnici”, con una limitata attenzione alla compatibilità tra scelte di uso del suolo e rischi e un ridotto o nullo coinvolgimento delle comunità locali. In questo lavoro, a partire da un approfondimento delle indicazioni fornite dalla Sendai Framework 2015-2030 per accrescere l’efficacia delle politiche di riduzione dei rischi e dall’esame di alcune delle numerose buone pratiche avviate nel corso dell’ultimo decennio in ambito europeo, si focalizza l’attenzione sulla Città Metropolitana di Napoli, area a elevata urbanizzazione e caratterizzata dalla compresenza di molteplici ed eterogenei fattori di rischio, con l’obiettivo di evidenziare i principali gap conoscitivi e le principali barriere che continuano a ostacolare sia un’accurata diagnosi dei rischi che possono interessare il territorio metropolitano sia la piena applicazione dei principi espressi dalla Sendai Framework per garantirne una più efficace gestione
Flood Risk Mitigation: from Engineering to Ecosystem-Based Measures. The Benevento Case Study
No full textBook of proceedings: Annual AESOP Congress, Spaces of Dialog for Places of Dignity, Lisbon, 11-14th July, 2017In the last two decades Europe has faced a strong increase of flooding events. Out of 325 flood events recorded from 1980 to 2012, indeed, more than 200 occurred in the 2000s (EEA, 2012). Among all natural hazards, more than 64% of the damages are due to hydro-meteorological events, namely to floods and landslides, with costs higher than 13 billion euros since 2000 (EEA, 2013a). If on the one hand the increase of heavy downpours can be ascribed to climate change, on the other hand the amount of damage has to be imputed to the significant, and sometimes uncontrolled, urbanization processes (EEA, 2017). Therefore, both of these matters have to be addressed in order to prevent future flood disasters. Climate change, intended as “a statistically significant variation in either the mean state of the climate or in its variability, persisting for an extended period”, is caused by “internal processes” or by “persistent anthropogenic changes in the composition of the atmosphere or in land use” (IPCC, 2001). The subversion of natural patterns has led not only to the increase of the sea level and of the mean temperatures but also to “changes in the frequency and magnitude of heavy precipitations” (EEA, 2017) that are expected to become even more frequent over the 21st century. Meanwhile, the population’s strong migration toward cities has enhanced the growth of urban areas with the consequent processes of land take and soil sealing (EC, 2012). In Europe, since the 1950s, the amount of impervious surfaces has registered an increase equal to 78%, with an increase of only 33% of the population (EC, 2012)Published versio
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
