Econeapolis: the park of Sebeto (1987 & 1989)
No full textThe basin of the Sebeto covers a triangular area of about 20km2, bordered to the north-east by the “Pendino” which saw the first settlement of Neapolis, in 474 B.C., and the hill of Capodichino, now the site of the airport; to the south-east the slopes of Vesuvius; and to the south, the sea.
The subsoil is alluvional and volcanic, while the surface soil is prevalently volcanic. The area was always marshy, and it conserved its natural state of equilibrium until it was built over during the last century. In the recent past three factors in particular have compromised this equilibrium: the imposition of a road network, the location of highly polluting factories and the sharp increase in residential density and building activity.
The first proposal for the Park of Sebeto goes back to 1987, and was presented during the Exhibition celebrating the 500th Anniversary of the Faculty of Architecture. It derived from the urgent need to liberate the city centre by decentralising factories that produced pollution and redistributing the urban modal points throughout the metropolitan area. The area which can still be safeguarded of the Sebeto basin covers some 900 hectares and was proposed as a Great Park with naturalistic, agricultural and recreational attributes.
The project included the repristination of the extant water courses and those which had been suppressed, and the creation of an artificial lake as a catchment area for the flood waters which cause periodic flooding in the eastern area of the city

No full textDalla tradizione positivista ottocentesca è derivato, come è noto, il mito dello sviluppo continuo dell’industrialesimo e dell’onnipotenza dell’uomo rispetto all’equilibrio biologico del pianeta.
Di fatto, i principali sistemi di sviluppo sociale, economico e tecnologico si sono strutturati nella convinzione che le risorse di energia della terra fossero illimitate.
Oggi, questa convinzione è palesemente in crisi. I “segnali di allarme” che vengono emessi dai sistemi biologici da cui dipende la vita del pianeta autorizzano Lester Brown ad affermare: “il bisogno di adattare la vita umana simultaneamente alle capacità di rigenerazione dei sistemi biologici della terra è ai limiti delle risorse rinnovabili e richiederà una nuova etica sociale. L’assenza di questa nuova etica è l’adeguamento: l’adeguamento del numero e delle aspirazioni degli esseri umani alle risorse e alla capacità della terra” (1992).
L’esplosione a catena della bomba demografica innescata dalla rivoluzione industriale e dilatatasi con legge esponenziale, ha trascinato con se una conseguente esplosione urbana che, potenziata dall’economia consumistica, ha determinato una pressione dell’ambiente naturale, praticamente incontrollabile.
In pratica: “la gente sta contemporaneamente in due modi. Come tutte le cose viventii noi abitiamo il mondo naturale, creato lungo 5 miliardi di storia della Terra da processi fisici, chimici e biologici. L’altro mondo è creato da noi; case automobili, fattorie, fabbriche, laboratori, vestiti, cibi, libri, dipinti, musica, poesia (e) poiché vivono entrambi i modi gli uomini sono coinvolti nello scontro fra l’ecosfera e la tecnosfera. Quella che chiamiamo crisi ambientale una sfilza di problemi irrisolti che vanno dagli accumuli di rifiuti tossici allo sconvolgimento del clima planetario, è un prodotto dell’innaturale accoppiamento tra processi ciclici, conservatori e perfettamente coerenti dell’ecosfera e quelli lineari, innovativi, ma ecologicamente disarmonici delle tecnosfere” (B.C.)
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
