    Progettare città aumentate antifragili

    E’ venuto il momento di entrare nel Neoantropocene (Carta, 2017), che definisco come una nuova era in cui l’umanità, invece di essere il problema, progetta e mette in atto la transizione verso lo sviluppo ecologico, riattivando l’antica alleanza tra componenti umane e naturali come forze coagenti: un antropocentrismo sensibile, rispettoso e temperato volto a riposizionare l’umanità in uno schema integrato, ibrido, con la natura. E lo strumento del nuovo paradigma urbano ecologico non può che essere una nuova “urbanistica circolare” (Carta, Lino, Ronsivalle, 2016), capace di progettare e rigenerare città, territori e paesaggi riattivando i loro naturali metabolismi, lavorando sugli scarti, progettando il riciclo e contrastando l’obsolescenza programmata delle città dell’Antropocene predatorio con la sua famelica necessità di espansione. Serve un nuovo paradigma di sviluppo a prova di cambiamento ambientale che fornisca anche rinnovata sostenibilità economico-ecologica (Raworth, 2017) all’alleanza tra dimensione urbana e rurale, guidando adeguate strategie reticolari (Schröder, Carta, Ferretti, Lino, 2017). Un progetto di nuovi pattern insediativi che eliminino il concetto di periferia come scarto prodotto dalla famelica espansione edilizia e relativa concentrazione di valori immobiliari e finanziari, stimolando la creatività degli habitat resilienti che stanno producendo pratiche dell’audacia in varie parti dell’Europa (Schroeder, Carta, Ferretti, Lino, 2018)

    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

    REPETTO D, Guillermo. Influenza humana y aviaria: pasado, presente y futuro. Rev. chil. pediatr., feb. 2006, vol.77, no.1, p.12-19. ISSN 0370-4106. Se revisa la epidemiolog\ueda de la influenza en los \ufaltimos a\uf1os y el brote en curso de influenza aviaria y sus riesgos para el hombre. En el siglo pasado hubo tres pandemias graves de influenza humana causadas por distintos subtipos de virus A que se extendieron por todo el mundo. Seg\ufan las evidencias cl\uednicas, de laboratorio y epidemiol\uf3gicas disponibles, existe un riesgo real de una nueva pandemia que eventualmente afectar\ueda al hombre derivada de la epidemia aviaria, A/H5N1, cuyo principal reservorio son aves migratorias. Se inici\uf3 en Hong Kong en el a\uf1o 2003 propag\ue1ndose con gran rapidez a la poblaci\uf3n av\uedcola en varios pa\uedses de Asia, Rusia, Macedonia, Colombia y Turqu\ueda. Chile no ha sido afectado. La trasmisi\uf3n ave-hombre est\ue1 documentada en un n\ufamero reducido de casos pero se teme que el virus, mediante recombinaci\uf3n gen\ue9tica con cepas humanas, adquiera la capacidad de infectar y trasmitirse al hombre dando curso a su diseminaci\uf3n explosiva. Se discute la estrategia, indicaciones y limitaciones de su prevenci\uf3n y tratamiento incluyendo vigilancia epidemiol\uf3gica, empleo de f\ue1rmacos antivirales e inmunizaci\uf3

    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

    Dispelling the Myths Behind First-author Citation Counts

    We 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 text
    We 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
