Parchi archeologici tra valorizzazione culturale e sviluppo locale archeologico
No full textArchaeological parks play a critical role in promoting a culture-led growth that connects the past and history with contemporary times, leading to a rediscovery of territorial identity and values, and driving innovation that opens to processes of social and economic growth, and supporting partnerships and collaborative frameworks among public and private actors that contribute to social and public value creation, strengthening the culture-led and local dimension of development within local communities. In this way, Campi Flegrei is an archaeological park that is able to bring together preservation and enhancement of archaeological sites, leading to a Community-Park able to act as a social actor which is embedded within territory and local roots and community, and to define a culture led landscape that is driving social innovation perspectives while shaping cultural ecosystems and districts
Cities and sustainable urban planning in transition
No full textSustainable development is advancing through cities that contribute to reducing pollution and energy consumes, managing efficiently energy uses, and behave as drivers of urban sustainability by rethinking an approach to redesigning urban planning. Cities are transitioning towards urban sustainability, meeting the needs of communities without compromising the wealth of future generations. Cities are playing a leading role in advancing towards urban sustainability, designing and implementing urban planning that has a positive impact for urban and natural ecosystems, and enabling citizens as responsible consumers and agents of social change. The future of sustainable urban development relies on cities redesigning urban planning, making healthy and efficient energy-led urban spaces, encouraging behaviours and actions for clean energy production, zero waste and emissions' reduction, promoting responsible consumption
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
Estrazione di DNA genomico da campioni biologici trattati con esteri cianoacrilici: tre diversi metodi a confronto
No full textObiettivo dello studio è stato confrontare tre differenti metodi di estrazione del DNA - Chelex® 100 Chelating Ion Exchange Resin (Bio-Rad), colonnine a scambio ionico NucleoSpin® Tissue (Macherey-Nagel) e microparticelle magnetiche NucleoMag 96 (Macherey Nagel) accoppiate ad estrattore automatico KingFisher mL (ThermoLabsystems) - al fine di tipizzare il profilo genetico di materiale biologico deposto su diversi substrati e trattato con esteri cianoacrilici. A tale scopo sangue, saliva ed una singola impronta digitale impressa per un tempo di 5 secondi sono stati deposti su cinque differenti superfici non porose: vetro, plastica, alluminio, calze di nylon e carta plastificata. Le tracce sono state prelevate e processate con due tempistiche differenti per ricreare sia le condizioni dell’analisi immediata (24 ore) che quelle dell’invecchiamento (30 giorni); per le medesime tempistiche sono stati allestiti anche i corrispettivi campioni negativi (“non trattati” con cianoacrilato). Tutti i campioni sono stati quantificati con RT-PCR e solo per quelli provenienti da estrazione con resina chelante è stata prevista un’amplificazione del gene della beta-globina con successiva corsa su gel di agarosio per osservarne la bontà. I risultati ottenuti - indipendentemente dalla tecnica estrattiva applicata - confermano per le impronte digitali impresse per un così breve tempo (5 secondi) quanto già osservato in un nostro precedente studio: non è possibile ottenere DNA genomico di qualità e quantità utile alla tipizzazione di un profilo genetico idoneo alla comparazione. Per quanto riguarda i differenti metodi a confronto, solo l’uso del Chelex 100 è risultato inadeguato, mentre sferette paramagnetiche e colonnine in silice possono essere considerate pressoché equiparabili. È inoltre possibile aggiungere che il trattamento di esaltazione delle impronte latenti con i cianoacrilati non comporta una successiva inibizione nei processi di estrazione e amplificazione del DNA
