Beyond a fragmented and sector-oriented knowledge for a sustainable and resilient urban development. The case of the Metropolitan City of Naples
No full textNumerous scholars have recently focused on the multiple challenges—from the environmental crisis to the impacts of climate change and natural and man-made hazards—threatening cities’ future. Most of them have clearly highlighted the increasing interdependencies among these threats, their close dependency on urban development processes, as well as the need for avoiding “policy silos and promoting cross-sectoral strategies in the face of these challenges. In this line, the contribution explores the interactions among urban development processes, loss and/or degradation of natural resources, climate change and disaster risks. Then, focusing on the Metropolitan City of Naples, it highlights difficulties and opportunities arising from a better integration of the available fragmented and sector-oriented knowledge, as a key step to provide planners and decision makers with a comprehensive understanding of human and natural dynamics capable to support cross-sectoral strategies for a sustainable and resilient urban development
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
Living with Risks: Changes in Risk Perception in the Campi Flegrei Volcanic Area (South Italy)
No full textCampi Flegrei (Southern Italy) is the largest volcanic caldera in Europe and one of the most densely inhabited all over the world. The Campi Flegrei region has been populated for millennia and has been well known for the episodic periods of uplift, subsidence and seismicity since Roman times. Nevertheless, also due to the long time that has passed since the last eruption, the population’s awareness of living in a high-risk area is quite limited. Furthermore, spatial and emergency planning in this area has been long neglected and often ineffective. Hence, following a brief description of the most recent volcanic events occurred in Campi Flegrei, this paper provides an overview of the emergency and spatial plans and of the risk communication activities so far implemented. Then, the results of a survey carried out in the last year highlight the main gaps in hazard and risk awareness as well as in the knowledge of the Disaster Risk Management (DRM) system. A comparison of the survey’s outcomes with those of a previous one, published in 2013, allows for the understanding if residents’ risk perception and awareness have changed due to the still on-going unrest phase. The outcomes of the survey may be useful to drive local authorities towards more integrated policies to improve resilience to disasters and implement holistic DRM at all levels, in line with goal 11, target 11.9 of the Sustainable Development Goals (SDGs)

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
