Managing historic cities under a new paradigm for urban conservation
This paper aims to present the limits of current urban heritage conservation practices and tools to cope with contemporary challenges and pressures affecting historic cities. It shows how, from the beginning of the 21st century, the international debate on urban heritage conservation has tried to reconcile heritage conservation with development building a holistic and integrated approach to urban conservation and management. The Historic Urban Landscape (HUL) Recommendation, adopted by UNESCO in 2011, embodies the key principles of a new paradigm for urban conservation and management. The paper discusses these principles and underlines the limits of its early implementation attempts. Finally, it identifies a research gap in the existing literature and presents the relevance, design and methodology of the PhD research that is currently being conducted by the author. It aims to stimulate the discussion on these topics and to test the research methodology chose
Linking Theory with Practice: Assessing the Integration of a 21st Century Approach to Urban Heritage Conservation, Management and Development in the World Heritage Cities of Florence and Edinburgh
Reconciling heritage conservation and development within the management of historic urban environments is recognised as one of the most challenging issues in the field of heritage conservation and urban management by academics and practioners. Existing urban heritage conservation policies, regulatory frameworks and tools operating around the world proved to be inadequate or insufficient in regulating urban transformations in historic urban environments. The "heritage versus development dilemma" has been a central argument in the 21st international discourse on urban heritage conservation management and development. UNESCO, the United Nations, ICOMOS and the Council of Europe have tried to overcome this persisting dichotomy through the adoption of a series of international texts. The evolution of a 21st century international discourse represents the international recognition that a "new paradigm for urban heritage conservation and management" has gradually taken shape since the beginning of the century. From this moment, urban heritage conservation can be seen as an all-encompassing, integrated urban management strategy, which incorporates the perspectives of urban planning and socio-economic development. The contemporary approach suggests moving beyond existing regulatory and management frameworks, recommending a revision of local practices so that they are consistent with the key principles of the new paradigm. However, there is still a need to carry out further research in order to understand how existing and consolidated urban management systems currently operate. This is a fundamental step towards effectively implementing the new paradigm into local practices. This interdisciplinary study aims to advance knowledge in the field of urban heritage conservation and management through a detailed assessment of the level of consistency of existing policies with the key principles of the 21st century approach. To the knowledge of the author, this is the first comprehensive and comparative assessment of multi-scalar (at national, regional, provincial and local levels) and multi-sectorial (including heritage conservation, urban planning and socio-economic development) urban management policies that has been carried out so far. To conduct this study, an original assessment framework was developed by the author with the objective of providing a qualitative evaluation tool which was able to link the international theory with local practices. The thesis focused on the two World Heritage cities of Florence (Italy) and Edinburgh (UK). It systematically demonstrated how some of the key principles of the new paradigm are already integrated into local urban management policies of these two historic urban environments. The study was first conducted by testing the assessment framework on the two case studies. Subsequently, a critical analysis of the two urban management systems was carried out, integrating the assessment results with data collected through semi-structured interviews with local stakeholders involved in the definition and implementation of the assessed policies. Finally, a comparison of Florence and Edinburgh's approaches to urban heritage conservation, management and development were illustrated and discussed. In this way, it was possible to discuss the strengths and weaknesses, opportunities and threats of different urban management systems in incorporating a 21st century international approach. Moreover, the study identified existing similarities and discrepancies between different approaches and to highlight good practices and critical aspects. The research findings constitute a step towards understanding whether a revision of existing policies and tools is necessary and how this could be done. The assessment results could be used by national and local governments to revise their current urban management policies according to the contemporary international approach to urban heritage conservation, management and development
Il ruolo delle Valutazioni di Impatto Ambientale e di Impatto sul Patrimonio Culturale: il caso di Liverpool sito UNESCO
Liverpool è una delle città più importanti del Regno Unito e, fin dalla seconda metà del XVII secolo, una città portuale di rilevanza mondiale. Dagli anni Trenta del XX secolo ed in particolare dalla Seconda Guerra Mondiale in avanti, l’espansione urbana e lo sviluppo economico della città hanno però sofferto di un intenso processo di declino che ha provocato la perdita di molti posti di lavoro ed una forte decrescita demografica. Per rispondere a tali cambiamenti socio-economici, l’inizio del XXI secolo ha visto la promozione di strategie di rigenerazione urbana basate sul patrimonio culturale della città, con l’obiettivo di trasformare l’immagine degradata della città in una realtà nuova, internazionale, creativa e dinamica,
nonché di stimolare la sua crescita economica. In questo contesto, l’articolo pone l’attenzione sull’iscrizione del centro storico di Liverpool nella Lista del Patrimonio Mondiale dell’UNESCO avvenuta nel 2004 con la denominazione “Liverpool-Città Marittima Mercantile”. Tuttavia, il sito UNESCO è oggi minacciato dai potenziali impatti negativi che Liverpool Waters – un importante progetto di rigenerazione urbana collocato
sia nel perimetro del sito UNESCO sia nella sua zona tampone (ulteriore zona di protezione del sito) – può avere sul suo patrimonio culturale. Nonostante sia in grado di attrarre grandi investimenti e di incentivare lo sviluppo economico della città, tale progetto potrebbe infatti irrimediabilmente danneggiare il Valore Eccezionale ed Universale (OUV) del sito, motivo per cui è stato iscritto dall’UNESCO nel 2012 nella lista del Patrimonio Mondiale in pericolo. Il conflitto tra le esigenze della conservazione del patrimonio culturale e quelle del processo di rigenerazione
urbana, evidenti nel caso di Liverpool, non costituiscono però un esempio isolato, come dimostrato da numerosi rapporti sullo stato di conservazione di altri siti UNESCO. Il caso di Liverpool, tuttavia, risulta particolarmente rilevante se si considerano le Valutazioni di Impatto Ambientale e di Impatto sul Patrimonio Culturale che sono state prodotte per conto di attori diversi con interessi divergenti (i promotori del progetto – Gruppo
Peel – e l’English Heritage – organismo pubblico incaricato della gestione del patrimonio culturale nel Regno Unito) nel valutare gli impatti potenziali che il progetto Liverpool Waters potrebbe avere sul Valore Universale ed Eccezionale del sito UNESCO. L’articolo ha l’obiettivo di descrivere criticamente gli strumenti di valutazione utilizzati in questo contesto, quali le Valutazioni di Impatto Ambientali (VIA) e di Impatto sul Patrimonio Culturale (HIA), identificandone i limiti e i punti di forza nel valutare gli impatti dei progetti sul patrimonio culturale e sull’OUV del sito in particolare. L’articolo presenta inoltre una comparazione tra l’HIA eseguita per conto dei rappresentati della conservazione del patrimonio culturale (English Heritage) e dei promotori del progetto (Gruppo Peel), che hanno portato a risultati opposti. In conclusione, l’articolo illustra la scelta effettuata dall’amministrazione locale, Liverpool City Council, riguardo la realizzazione del progetto Liverpool Waters dopo aver preso in considerazione i diversi risultati delle HIA effettuate

Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
