Trayectorias tecnological creativas y redes largas
No full textIl saggio è stato scritto per un libro uscito con contributi di economisti e sociologici dell'America Latina il cui incontro è stato promosso dalla rete LENTISCO (Latin American Network on Technology Innovation and Co-Development Studies. Il saggio esamina le possibilità di realizzare traiettorie tecnologiche alternative alle logiche del neoliberismo i cui prodotti siano nella direzione di una maggiore qualità della vita per le persone che lavorano in questa traiettoria, per gli utenti dei prodotti e per la valorizzazione e tutela delle risorse ambientali
For a polycentric Europe. How to save innovation from liberism
No full textIl libro finanziato dalla Comunità Europea (porgetto INTERREG III) presenta una analisi delle politicheeconomiche europee viste dal punto di vista della innovazione tecnologica rilevandone le contraddizioni interne (una politica economica e tecnologica più orientata al modello di economia solidale per le nazioni stati membri e una politica più orientata al modello neolibersita nei confronti delle nazioni fuori dall'Europa). Dopo questa analisi generale il libro riporta numerose buone patriche considerando sei tematiche a partire dalla innovazione tecnologica: (a)Innovazione e partecipazione; (b)Innovazione e relazioni tra nazioni; (c) Innovazione nelle direzioni tradizionali dell'artigianato, industria e agricoltura; (d)Innovazione in materia di ambiente ed energie rinnovabili; (e) Innovazione e qualità della vita;(f)Innovazione creatività ed arte
Traiettorie tecnologiche e reti lunghe
No full textIl saggio presenta una definizione originale di "traiettoria tecnologica creativa" per identificare delle traiettorie tecnologiche che, sulla base di dieci criteri individuati, producono complessivamente un aumento della qualità della vita in alternativa alle strategie neoliberiste in cui si cerca solo il maggior profitto dell'impresa . Nel saggio sono presentati quattro casi internazionali di traiettorie tecnologiche creative (il caso dell'Associazione Migrzie e sviluppo del Marocco, il caso dell'UCIRI produttore di caffè in Messico, il caso della Grameen Bank nel Bangladesh in India, il caso delle innovazioni tecnologiche a favore di persone disabili e anziane del Danish Centre in Danimarca)
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
Description and validation of an analytical method for the determination of paromomicyn sulfate in medicated animal feeds
No full textA procedure for the extraction of paromomycin from different animal feed matrices (rabbit, chicken, pig feeds) and its subsequent determination via a reversed-phase ion-pair HPLC separation coupled with pulsed amperometric detection is described. The procedure optimised in terms of the extracting solvent and the solid phase extraction stationary phase allows the total recovery of the aminoglycoside antibiotic. The criteria used for the validation of the analytical method applied to the cited matrices are the linear dynamic range of the response, the detection limit, the repeatability, the intermediate repeatability and the accuracy. A comparison with a method described in the literature for the bulk analysis of this antibiotic is made
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
Trayectoria tecnological creativas y redes largas
No full textIl saggio affronta i temi della innovazione tecnologica cercando alternative al modello neoliberista e proponendo una analisi innovativa del concetto di "traiettoria tecnologica creativa" . Questa analisi ritenuta importante per nazioni come il Cile presenta alcune concrete esemplificazioni di questo concetto. Il saggio riprende un saggio già scritto dai due autori ma ripensato per il contesto, quello cileno, in cui è stato collocato
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
