The slums affect the future of the metropolis
No full textThis work, that is part of a current research, is aimed to tackle the problem of uncontrolled city growth. Urban sprawl has recently become a critical issue not only from the spatial point of view, but also for overcrowding.
The main objective of this study is to point out the need for a proper planning of the largest urban areas in the world by means of a strategic project. Also, the need for a functional organization of the so-called slums is worth considering.
Slums are usually left out from the well-organized urban system. Although they can easily be identified within the city, they are not formally recognized from the perspective of soil occupation and the related social issues.
In the light of this, planners are increasingly given important responsibilities as well as a set of different tasks. In fact, besides the multi-disciplinary approach, they should deepen the correlation between space and the population.
The explosion of megacities, along with the prospect of further settlements in the world, involve a mixture of people, cultures, religions, education, interests, and technologies which undermine the traditional planning methodologies. In fact, this situation affects the functional integration and the development of a participatory process.
This current research will provide new methods and new models so as to analyze the phenomenon, both large-scale and the small-scale aspects
Urbanistica conflittuale tra città e slum. Criticità di Governance
No full textCon questo lavoro si vuole porre in evidenza il profondo cambiamento storico che le città contemporanee stanno attualmente vivendo. In molti Paesi del mondo, in ambienti diversi, per contesto, aspetti culturali, sociali ed economici, le grandi metropoli si confrontano con nuove realtà insediative: gli slum. Questi 'nuovi luoghi', spesso a ridosso della città o all'interno della stessa, portano alla necessità di una riprogettazione del tessuto urbano consolidato. È dunque, sempre più di attualità, l'esigenza che la pianificazione delle grandi aree urbane, localizzate nei diversi continenti, affronti, attraverso un disegno strategico il problema dell'organizzazione funzionale, non solo delle realtà esistenti, ma anche e soprattutto degli slum che hanno infranto la 'diga' dell'urbanistica ufficiale proponendosi con forza come la chiave di volta per il futuro sviluppo della città
Il cambiamento multietnico dell'abitare nei centri storici. Un quartiere di Cagliari come modello di discussione.
No full textCon questo saggio gli autori si propongono di analizzare le trasformazioni, anche spontanee, disordinate e repentine nelle città, come sfide costruttive per l'urbanistica contemporanea.
Mediante un caso esemplificativo: un quartiere del centro storico di Cagliari, si ragiona sulle determinanti urbanistiche ed edilizie, che interagiscono con la nuova domanda insediativa composta, in gran parte, da quella che caratterizza le nuove migrazioni nella città
Beni comuni dello spazio urbano
No full textIl libro, pur considerando che il tema dei beni comuni, o common good, è molto trattato in letteratura con riferimenti e formule ampie, si sofferma sugli aspetti meno dibattuti che riguardano la connessione dei beni comuni con le peculiarità territoriali e soprattutto con la città, considerata il principale riferimento di studio e di creatività. Infatti lo spazio urbano, o urban space, non soltanto svolge un ruolo chiave per conoscere ed interpretare l’habitat su cui si fondano i contenuti e le regole dei beni comuni, ma consente inoltre di sviluppare un processo integrato per modellare e rimodellare le complessità tra principi, aspirazioni degli abitanti e diversi interessi. La città, dunque, come artefatto e come spazio di relazioni positive che, guidata da una buona urbanistica, può incoraggiare la progettualità e l’affermazione di beni comuni sia pubblici che privati. Questo percorso, tuttavia, non è facile perché è influenzato da fattori politici e religiosi, della tradizione e dell’economia che caratterizzano le infinite realtà del mondo, dove si preferisce ignorare il divario sociale ed economico tra le popolazioni privilegiate delle città formali e tutti coloro che vengono privati delle necessità primarie come l’istruzione, l’assistenza sanitaria e i servizi indivisibili. Un aspetto non marginale della politica urbanistica perché da un lato confligge con la giustizia sociale e dall’altro può condizionare le istituzioni democratiche fino a distorcere il significato epistemologico di “bene comune” e la sua traducibilità in fatti concreti. L’argomento del libro è suddiviso in tre parti. Nella prima si esaminano i beni comuni negli aspetti giuridici, economici, sociali e culturali con le applicazioni al territorio. Nella seconda parte il racconto si sofferma sui beni comuni riferiti alla grande dimensione dell’ecosistema e dell’ambiente. Nell’ultima parte, che comunque sottintende tutte le pagine del volume, si affronta la tematica dei beni comuni e la relazione con gli spazi urbani nei quali si possono costruire e affermare. Infine, a conclusione dei diversi capitoli gli autori prospettano alcuni interrogativi con l’intento di attivare un dibattito, sia pure virtuale, per approfondire gli argomenti e per riflettere sugli scenari possibili di intervento
The Paths of History for Multicultural Tourism: a Smart Real World in the Metropolitan City of Cagliari (Italy)
Full text linkRecently, the ways of visiting and enjoying the city have changed substantially, as well as the interest in places which are less visited in the classic points of interest-POIs (Matoga et al., 2018). This brings to light new forms of a multicultural tourism, which however activate fruition processes not yet planned and managed within the classic rules of sustainable development, resilience and the protection of cultural and historical authenticity of places. For these reasons, the main objective of this article is to focus on cultural integration in the Metropolitan City of Cagliari, constituted by 17 Municipalities in the South of Sardinia (Italy), in order to provide smart tourism solutions in a real context. The territory of the Metropolitan City of Cagliari is characterised by different types of undervalued or little known POIs (nuraghes, churches, historic centres, religious manifestations, religious festivals, and manifestations of identitarian tradition), which, however, are part of a heritage of absolute value that cannot be compared. Therefore, the working hypothesis is to redefine the concept of cultural good in its tangible or intangible form, in order to constitute a system with other POIs located in the metropolitan context. In relation to these assumptions, the paper wants to propose an integrated model of singular POIs and habitats, after describing the historical and cultural peculiarities of the Metropolitan City of Cagliari
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
