Assessing the Economic Value of the Unmovable Cultural Assets for Improving Their Resilience: The Case Study of the Church of Santa Maria dei Miracoli
No full textCultural Heritage is exposed to many stresses and risks due to climate change, natural events, and human actions. During the last decade, the interest in risk reduction and risk assessment is getting significant attention, also for cultural assets. The current challenge is improving their resilience to safeguard and valorize them for future generations. This contribution is related to the European project of ResCult, “Increasing Resilience of Cultural heritage: a supporting decision tool for the safeguarding of cultural assets.”(2017; 2018). The present paper focuses on assessing the economic value of the Church of Santa Maria dei Miracoli (Venice, Italy) as a component of the risk assessment. The proposed contribution applies the Travel Cost Method (TCM) to evaluate the economic value of the considered cultural asset. Finally, this contribution discusses the current state of the art of risk assessment in the European context, focusing the attention on its fragmentation. Moreover, the present paper reflects on the possible implementation of the proposed method at the European scale
Evaluation of Ecosystem Services in Mining Basins: An Application in the Piedmont Region (Italy)
Full text linkMining activities impact on the territorial system in various ways, affecting its environmental
and socio-economic components. Specific evaluation tools can support decision-making
processes in the context of the sustainable planning and management of mining activities. Within the
evaluation procedures of mining activities, a growing interest in the analysis of Ecosystem Services
(ES) is emerging. ES refer to the benefits that the natural system delivers to society, linking the health
of ecosystems and human well-being. Starting from a real-world case related to the adoption of
the Regional Plan of Mining Activities (PRAE) of the Piedmont region (Northern Italy), the paper
aims to explore the ES valuation by considering three different mining quarries. The state of the
art of the basins is compared with alternative planning scenarios from the point of view of the
ES produced. The valuation is developed through GIS and the Simulsoil software, detecting the
biophysical benefits produced and estimating their economic performance. The simulation results
can be used to support the formulation of planning strategies, estimating the trade-offs in terms of
competitive land-use values. The study also demonstrates that the integration of ES into Strategic
Environmental Assessment (SEA) can produce a comprehensive impact assessment of a mining
project, guaranteeing the protection and valorisation of the environmental system
New Cohesion Policy 2021–2027: The Role of Indicators in the Assessment of the SDGs Targets Performance
No full textThis contribution aims to develop an integrated model of analysis and assessment for the valorisation and management of green spaces, with particular regard to historic gardens. The model is based on the combination of two main tools: on the one hand, the Geographic Information Systems (GIS), employed for the classification and geolocation of green areas, following the Italian legislation in force on Minimum Environmental Criteria (CAM), and on the other hand, an extended version of the SWOT Analysis, that aims at identifying the strengths, weaknesses, opportunities and threats both at the state of the art and a potential future scenario. The combination of the two tools is applied to a real case study in Northern Italy: the Royal Gardens of the City of Turin (Italy), known for their historical, social, economic and ecosystem-urban values. GIS systems and SWOT analysis can be used in parallel and provide distinct results, or be combined, in the ex-ante, in-itinere and ex-post phases of the assessment process, thus providing valid support to planners and Decision Makers, in the definition of strategic guidelines of valorisation and management of historical green heritage in the medium and long term, as well as professionals and specialized bodies to optimize the care and management of this heritage
COME ESPLORARE LA RESILIENZA NEI SISTEMI URBANI E TERRITORIALI? UNA PANORAMICA SUI MODELLI DINAMICI
No full textIl presente paper offre un’indagine sui modelli dinamici nel supportare i processi decisionali relativi a
politiche e azioni per rendere le città più resilienti. Il concetto resilienza urbana è stato recentemente
riconosciuto come una questione importante nella pianificazione territoriale e urbana. La resilienza urbana è
definita come la capacità del sistema urbano e delle sue dimensioni di cambiare, adattarsi e trasformarsi a
perturbazioni e shock. In questo senso, l’impiego di strumenti di valutazione a supporto dei pianificatori e dei
Decision Makers è utile per valutare la natura dinamica e multidimensionale della resilienza e dei suoi effetti
sulle performance di scenari di trasformazione urbana. Questo documento analizza la famiglia di modelli
dinamici che consiste in una serie di metodi matematici che utilizzano un insieme di equazioni differenziali
ordinarie per prevedere il comportamento evolutivo di sistemi complessi nel tempo. Questi modelli sono
considerati utili per la valutazione di sistemi urbani complessi, soprattutto se integrati in quadri metodologici
ampi per raggiungere obiettivi di resilienza urbana. Tra i diversi modelli dinamici, il presente contributo si
focalizza su due modelli specifici: i System Dynamics Model, impiegati nella pianificazione e modellizzazione
degli scenari, e i sistemi cooperativi Lotka-Volterra che sono adatti per prevedere future dinamiche territoriali
a partire da un sistema di indicatori e indici
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
