The Porticoes of Bologna: Methodology for sustainable restoration
No full textThe restoration, in this specific case, should be understood in the broadest sense of its meaning: no more, therefore, the restoration of a single monument, but the restoration of an urban tissue, the historical centre of Bologna, that counts about 38 kilometres of porticoes built since the XI century; many of them could be considered as examples of vernacular architecture. The research proposes methodological criteria of inter-vention based on the different types of flooring present in the local building situation in relation to their spe-cific conditions of degradation. The courses of action with their operational indications, indifferent to the con-cept of distinction between greater or lesser architectures, are proposed as a cultural act for the protection and enhancement of the entire urban heritage
Bela pseudoappeliusi n. sp. (Neogastropoda: Mangeliidae) from the Plio-Pleistocene of Italy
No full textABSTRACT - A new species of mangeliid, Bela pseudoappeliusi (Neogastropoda, Conoidea), is described from the Plio-Pleistocene of
Italy. The systematic description is based on a series of eleven specimens selected from the numerous findings in northern and central Italy
(Piedmont, Emilia-Romagna, Tuscany and Lazio). The new species shows affinities to Bela (s.l.) appeliusi (Bellardi, 1877) with regard to
particular features such as shell dimension, teleoconch sculpture and aperture morphology. The study includes a detailed survey of the type
locality as well as a brief account of occurrences at other localities

No full textLa classificazione dei taxa plio-pleistocenici della famiglia Mangeliidae è da sempre un argomento difficile, che si presta a controverse interpretazioni.
Gli autori, come nei precedenti volumi, hanno posto alla base delle loro analisi il reperimento dei tipi e le loro definizioni originali, pietre miliari della ricerca tassonomica. Questo approccio ha permesso di verificare,
ad esempio, come alcune specie siano definite da serie tipo ormai scomparse e da descrizioni non sufficienti a caratterizzarle. Gli autori, in questi casi, hanno determinato gli esemplari studiati sulla base dell’iconografia
(quando possibile dei tipi) e delle pubblicazioni successive, pur con il beneficio del dubbio, esteso anche a tutte le citazioni precedenti della specie, che suggerisce la necessità di reperire dei topotipi e designare un neotipo.
Questi casi documentano la serietà della loro revisione (vedi nota dei curatori
del vol. 1). Nella determinazione degli esemplari fossili gli autori hanno preso in considerazione
anche i taxa attuali del Mediterraneo con relative problematiche tassonomiche, condizione indispensabile per affrontare la classificazione e la determinazione delle specie plio-pleistoceniche. Può essere motivo di
discussione l’elevato numero di nuove specie proposto; ma negli studi sulla biodiversità è più opportuno segnalare nuovi taxa che trascurarne le peculiarità ed affossarne forse per sempre la possibilità di una distinzione. Saranno le ricerche future che decreteranno la validità o meno di queste nuove
specie. La classificazione e la determinazione dei Conoidea hanno sempre rappresentato
uno scoglio notevole e come conseguenza la loro utilizzazione per analisi biogeografiche e/o sulla biodiversità è sempre stata limitata. In letteratura infatti sono stati prevalentemente utilizzati gruppi con classificazioni
più consolidate (ad esempio i bivalvi) e quindi con distribuzioni stratigrafiche, biogeografiche ed ecologiche più affidabili. Vorremmo ricordare, concludendo, che l’obiettivo di partenza degli autori era proprio quello di fornire un contributo alla possibilità di utilizzare correntemente questo taxon per analisi biogeografiche e paleoecologiche nel Plio-Pleistocene
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
