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
Differential effects of grammatical gender and gender inflection in bare noun production
No full textIn a new series of experiments with the picture–word interference paradigm, we replicated the grammatical gender interference effect in bare noun production in Italian: naming times are slower to picture–word noun pairs sharing the same gender. This effect is independent from the morphological transparency for gender, but responses are significantly slower when the distracters are transparent for gender. Overall, the pattern of results supports the assumption that in bare noun production grammatical gender is always selected, at least in languages like Italian.We assume that the differential effects of the nominal endings are due to the mechanisms involved in the recognition of grammatical gender of the distracter nouns which are sensitive to the morphological transparency for gender: lexical representation of transparent written words leads to a higher level of activation, thus resulting in stronger gender interference
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
Giulio Troili:teoria e prassi della quadratura nel tempo di Valerio Castello e dei protagonisti della grande decorazione a Genova
No full textLa prospettiva, Giulio Troili scrive in Paradossi, «è il polo, dove si raggira l’arte del disegno...apporta luce e splendore alla pittura», è scienza della rappresentazione . Egli si pone sulla strada iniziata da Leon Battista Alberti, percorsa da Piero della Francesca, da Dürer, da Vignola, distinguendo la prospettiva dalla scienza della visione, l’ottica. Abile architetto ed interprete dell’architettura dipinta in prospettiva, la Quadratura, Troili estende le sue informazioni oltre che ai pittori, agli scultori e agli architetti. Con onestà, e lucidità critica, ricorda di aver studiato gli scritti di Alberti, il primo ad usare il velo , di aver consultato le pagine di Piero della Francesca, di essersi entusiamato per i disegni di Dürer. L’artista e scrittore tedesco, servendosi di mezzi meccanici (lo sportello) oltre che matematici, assicurava esattezza prospettica alla prassi artistica. Ha letto gli scritti di Daniele Barbaro, ma soprattutto ha utilizzato quelli di Vignola. Il “Paradosso”, così i contemporanei chiamavano Troili, concorda nella metodica e nelle formulazioni teoriche con la lettura di Le due regole della prospettiva pratica di Vignola, commentate e diffuse nel 1583 dal domenicano Egnazio Danti . Troili continuerà a mantenere viva a Bologna, per tutto il secolo XVII, l’attenzione alla produzione letteraria, architettonica e prospettica, del Barozzi. Architetto del Senato e quadraturista, è partecipe del fascino delle ‘macchine’ che abbraccia tutto il Seicento e che si estende a tutti i campi. Cerca di rendere la pratica della prospettiva architettonica più agevole e celere mediante l’aiuto della sua ‘macchina’: un velo nero applicato ad un telaio mobile. Lo dichiara preferibile alla pratica della graticola, «perché con questo velo si taglia matematicamente, a traverso la piramide visuale, e scioglie qualsivoglia nodo di difficoltà» . Egli, ed è questa la sua grande qualità che lo pone in dialogo con la tradizione bolognese, si muove nella direzione della struttura architettonica illusionistica a successione di piani, valorizzandone l’ardimento tecnico e interpretandola secondo le regole della geometria descrittiva e proiettiva, della stereometria o geometria solida. Credo che possiamo anche noi condividere con i contemporanei l’interpretazione del suo soprannome, “Paradosso”, quale sinonimo di audace
