Towards a risk informed planning process: the main outcomes of the Armonia Project
No full textThe European Project “Applied multi Risk Mapping of Natural Hazards for Impact Assessment” was aimed at proposing hamonized methodologies to produce integrated risk maps informing more effectively the spatial planning process in areas prone to natural hazards.
On the ground of the work carried out in the Project and of the many questions it has risen, the paper draws out the methodological and operative conclusions that have been achieved, focusing on the following issues:
-the challenge to “harmonize” different disciplinary fields and competencies;
-the wide spectrum of planning systems in Europe and the different perspectives making difficult to choose the “valuable” information for a well informed planning process in risky areas.
From the discussion of the latter questions, the paper will move on describing the methodological framework that the Project has embedded into a decision support system for planners. The latter is designed to link the knowledge-base in terms of hazard, vulnerabilities and risks, with land use planning choices at different scales. The methodology behind the DSS to guide planners in this complex endeavour constitutes a significative innovation with respect to the current European state of art. In order to verify its applicability, a test was carried out in the area of the Arno riverbasin and its results will be shown in the paper.
Finally, the inevitable limitations of the project will be discussed opening the floor for future research needs
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
Un manuale per i centri storici in zona sismica: esperienze e proposte
No full textIl contributo presenta i risultati di una ricerca dal titolo "La salvaguardia dei valori storici, culturali e paesistici nelle zone sismiche italiane", svolta nel biennio 2003-2004 e confluiti in un volume a stampa pubblicato nel 2006.
