Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Codice Internazionale sulla Commercializzazione dei sostituti del latte materno : le conoscenze delle ostetriche
No full textObiettivi. Scoprire le violazioni del Codice Internazionale sulla Commercializzazione dei sostituti del latte materno in Italia e valutare la conoscenza del codice da parete delle ostetriche.
Metodi. È stato eseguito uno studio randomizzato di un campione di 108 ostetriche, somministrando dei questionari.
Risultati. Il 40% delle ostetriche ha dichiarato di non conoscere il codice. Solo il 27% delle ostetriche afferma di sapere le regole sull’etichettatura e il 32% di conoscere le norme sulla commercializzazione dei sostituti del latte materno. Riguardo agli articoli che regolano la pubblicità (73%) e la promozione (76%) degli alimenti per lattanti, la percentuale di conoscenza è alto, ma non sufficiente. All’ultima domanda, le ostrtriche hanno dichiarato che in Italia il codice non è così divulgato.
Conclusioni. Le ostetriche italiane non conosco molto bene il codice e questo avvenimento influenza le violazioni del Codice Internazionale. Quindi tutte le ostetriche dovrebbero conoscere queste regole e utilizzare quest’ultime nella loro pratica professionale. Pertanto dovrebbe essere fatta una campagna per informare tutte le ostetriche sul Codice Internazionale sulla Commercializzazione dei Sostituti del Latte Materno
Variations on the Author
No full text“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
No full textWe 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
Bologna medievale, GIS e Google Earth: nuove forme di pubblicazione e fruizione per la ricerca
No full textSi presentano qui i risultati preliminari di una ricerca in progress sull’analisi degli spazi pubblici e privati in Bologna medievale. Per il XIII secolo è disponibile una massa particolarmente ingente di fonti documentarie che consentono di avere una buona quantità di informazioni sul patrimonio immobiliare urbano e sulla destinazioni degli spazi. Il trattamento seriale di tali fonti ha consentito di realizzare un sistema informativo geografico (GIS) che sta restituendo una interessante descrizione degli spazi urbani e della composizione dei patrimoni immobiliari familiari. Il GIS fornisce un valido aiuto alla ricerca grazie alla capacità di raccogliere e visualizzare sulla città le informazioni che si hanno su di essa, ma consente inoltre di distribuire in forma grafica tali dati su Web, anche attraverso semplici sistemi di navigazione territoriale. Per questo motivo è stata avviata una ulteriore fase del progetto che ha come obiettivo la pubblicazione delle informazioni contenute nel GIS sul visualizzatore territoriale 3D Google Earth per poter raggiungere e coinvolgere anche utenti non necessariamente esperti di tematiche storiche
Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
