Valutazione ambientale strategica, piani urbanistici comunali e piani dei parchi. Un quadro operativo per l’integrazione della Strategia regionale per lo sviluppo sostenibile della Sardegna
Full text linkLa concezione della sostenibilità, nel governo del territorio, va oltre la tutela dell’ambiente in quanto, oltre il profilo ambientale, include quelli economici e sociali.
Si evidenzia, quindi, la necessità di rendere compatibili le esigenze dello sviluppo economico con quelle della tutela delle risorse naturali, e dell’equità e del progresso sociale. In quest’ottica, la Regione Sardegna ha approvato la Strategia regionale per lo sviluppo sostenibile (SRSvS), quale declinazione della Strategia nazionale, in coerenza con l’Agenda 2030 delle Nazioni Unite.
Il volume presenta e discute i risultati di una ricerca sviluppata durante lo svolgimento del Laboratorio di ricerca azione SOSLab1 del Progetto SOSLabs, condotto, presso l’Università di Cagliari, nell’ambito del bando emanato nel 2019 dalla Direzione Generale per lo Sviluppo Sostenibile, per il Danno Ambientale e per i Rapporti con l’Unione Europea dell’allora Ministero dell’Ambiente e della Tutela del territorio e del mare (oggi Ministero dell’Ambiente e della Sicurezza energetica).
Gli esiti si basano su un approccio metodologico che integra la SRSvS nella prassi della pianificazione territoriale e urbanistica nel contesto comunale e metropolitano, tramite un modello in cui la costruzione del piano è permeata dalla valutazione.
Si assume quale riferimento scientifico e tecnico la valutazione ambientale strategica (VAS), in virtù del suo essere profondamente innervata nel processo di piano, quasi ad identificarsi con il piano stesso, sia nelle fasi preparatorie, che attuative. La metodologia di integrazione della SRSvS nel processo di pianificazione e valutazione è applicata, sperimentalmente, a due piani urbanistici: il Piano urbanistico comunale preliminare del Comune di Cagliari e il Piano del Parco naturale regionale di Tepilora
A Methodological Approach for Identifying Hotspots of Regulating Ecosystem Services: Insights from Campania and Sardinia, Italy
No full textThe assessment of ecosystem services (ESs) plays a vital role in spatial planning and land-use decision-making. While ecosystems provide both tangible and intangible benefits essential for sustaining life, land-use changes driven by spatial planning influence the distribution and health of ecosystems, thereby affecting ES provision. To effectively identify priority areas for ES supply, it is essential to analyze ES hotspots, i.e., clusters of areas where individual ESs or bundles of ESs are delivered at high levels. Within this context, this study introduces a methodological approach for delineating ES hotspots. The first step involves a biophysical assessment of ESs, which here focuses on three regulating ESs: habitat quality, reflecting ecosystems’ capacity to provide niches and nurseries for wildlife; carbon storage and sequestration, indicating their role in climate mitigation; and land surface temperature, serving as a measure of local temperature regulation by vegetation and unsealed soils. In the second step, various spatial statistical techniques for hotspots identification are integrated to reduce the sensitivity associated with relying on a single method. The proposed approach is applied in the Italian regions of Campania and Sardinia, revealing significant differences in the extent and the spatial distribution of areas that serve as hotspots for all three ecosystem services. The proposed approach to ES delineation can be readily applied in any context where ES biophysical assessments are available. Besides aiding the identification of key areas for ES supply, it provides planners and decision-makers with robust, easily communicable information that can be effectively understood by a broader audience
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
Do the construction of new major cultural infrastructure and related urban beautification contribute to stimulate economic development, social upward mobility, social mix and public engagement? A comparative study concerning London, Cagliari and Rome.
Full text linkCultural policies have assumed increasing importance in urban regeneration processes. However, the contemporary academic debate makes a clear distinction between “urban Regeneration” and “urban Renaissance” on the basis that interventions really solve social and urban inequalities or rather exacerbate them by fostering gentrification.
The aim of this study is to contribute to this debate. For this reason, three examples of cultural regeneration that tried to achieve the regeneration of a whole neighbourhood by combining the opening of an art centre with a series of activities addressed to the local community are analysed. The first one is the Bankside programme, developed between the XX and XXI Century in the ward of Cathedrals in the London Borough of Southwark. The second one is the Local Centre for the Arts and Culture La Vetreria realised during the first decade of the XXI Century in the neighbourhood of Is Bingias in Cagliari. The third one is the Auditorium Parco della Musica constructed during the first decade of the XXI Century in the neighbourhood of Flaminio in Rome.
After identifying in the literature the difference between Regeneration and Renaissance, the parameters to conceptualise gentrification and the methodologies applied in previous studies, a methodological framework is specifically tailored for this study. Accordingly, the analysis is organised in two complementary parts. The first one focuses on the tangible (hard) effects of the opening of the three cultural centres through visual, quantitative and qualitative analysis. The second one focuses on the intangible (soft) part and enquires about the activities of the regeneration programmes through qualitative research.
It shows that the construction of new cultural infrastructure and the related urban beautification are not able, on their own, to determine economic development, social upward mobility, social mix and public engagement. On the contrary, they are part of a complex set of factors that, as a whole, contribute either to accelerate the already existing patterns or collaborate in promoting local strategies within a set of congruent actions. Consistently, the Tate Modern Gallery, while collaborates to determine the improvement of the area in many respects, encourages gentrification, La Vetreria does not improve either the neighbourhood conditions or the socio-economic status of the local community and the Auditorium Parco della Musica contributes to ameliorate the area without determining any major negative consequences.
This study provides a threefold cognitive contribution, of which the constituents are illustrated below.
(i) Methodological aspect: it develops a comprehensive multi-method approach that assembles visual, quantitative and qualitative analysis, explicitly drawing from the epistemological analysis of literature both in terms of conceptualisations and methodological frameworks, and by distinguishing between tangible and intangible effects.
(ii) Empirical aspect: it is a pioneering work structured around a rigorous longitudinal, comparative ward level analysis, never done before in none of the studied contexts, based on the process of raw data from a variety of sources and the building of a multi-factor analysis that interpret relationships and patterns of change over two decades, complemented by visual and qualitative analysis; applied to the three case studies analysed.
(iii) Theoretical aspect: it critically bridges between theoretical and methodological debates ongoing in the international arena on the subject matter. While the empirical findings contribute to this wide debate, the study also challenges the effectiveness of cultural Regeneration by critically opposing state-led gentrification versus social upward mobility, and records a case of supergentrification, thus contributing to an additional theoretical phenomenon that has recently emerged
Beyond environmental protection and conservation: local-level implementation of the 2030 Agenda to deliver universal goals and targets. Lessons from Sardinia, Italy.
Full text linkAccording to the 2030 Agenda, sustainability is no longer restricted to environmental protection and conservation, but it also needs to consider economic and social issues. This poses new challenges to urban planning and territorial management, that require new procedures to practically implement the global goals into local policies to effectively deal with counteractive priorities. This study proposes an innovative approach aimed at harmonizing local plans and the Sardinia’s Regional Strategy for Sustainable Development. A new tool, which integrates the objectives of the Regional Strategy for Sustainable Development into local plans and simultaneously assesses the efficiency of these strategies in the related spatial context is defined and applied
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
Overtourism: How the city of Cagliari is losing its soul
Full text linkThis study contributes to expanding the knowledge on overtourism by delving into the
case study of the Italian city of Cagliari, which has undergone through a series of urban regeneration
programs and implemented a set of policies to encourage tourism growth. The overarching por-
trayal of Cagliari depicts a city in the midst of a touristification process, which is profoundly altering
the physical landscape and the social composition of its neighborhoods, progressively transformed
into entertainment hubs. In the overcrowded urban spaces that ensue, former residents frequently
experience discomfort, prompting many to seek relocation. Consequently, the traditional local com-
munities are fading away, heralding a gradual and irreversible vanishing of the soul of the city
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
