Mémifier la politique. Genre, stéréotypes et détournement
No full textDans Mémifier la politique. Genre, stéréotypes et détournement, l’ouvrage explore un phénomène émergent de la communication publique : les mèmes. Ces artefacts numériques, conçus pour la viralité et la visibilité dans les espaces numériques, ne peuvent plus être réduits à de simples expressions frivoles en marge des discussions politiques. Ils doivent être compris comme des pratiques quotidiennes par lesquelles les citoyens s’engagent politiquement et redéfinissent les cadres de l’idéologie dominante.
En tant qu’artefacts politico-culturels divertissants, les mèmes génèrent des significations collectives et partagées, se propageant « de cerveau en cerveau ». Ils participent ainsi à un processus de "mémification" de la sphère publique, caractérisé par deux dynamiques principales : d’un côté, l’offre de nouvelles opportunités de participation et de mobilisation ; de l’autre, une imprégnation de l’idéologie dominante.
Cette contribution analyse deux dimensions critiques : (1) les problèmes liés aux mécanismes de stéréotypage de genre face aux opportunités de polyvocalité et d’élargissement de la participation ; (2) les processus de recadrage et de détournement visant à subvertir les cadres stéréotypés à travers le langage fluide de l’anti-idéologie. Ces deux aspects sont explorés et illustrés par une étude de cas récente en Italie
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
INFLUENZA DI TRATTAMENTI OMEOPATICI E DI CAMPI ELETTROMAGNETICI DEBOLI A BASSA FREQUENZA SU MODELLI VEGETALI
No full textL’efficacia dell’omeopatia è tuttora oggetto di acceso dibattito e, nonostante le numerose ipotesi formulate, il suo meccanismo d’azione non è ancora stato totalmente chiarito e non esiste una teoria comunemente accettata. Situazione analoga si riscontra per quanto riguarda gli effetti biologici dei campi elettromagnetici deboli a bassa frequenza. Tali effetti, che dipendono in modo complesso dalla intensità e frequenza del campo magnetico e dalla durata del trattamento, sono stati ampiamente studiati sull’uomo e sugli animali e, negli ultimi anni e in misura sicuramente minore, sulle piante. Anche in questo caso sono state formulate numerose ipotesi per spiegare l’interazione di tali campi con il bio-oggetto, ma finora non si hanno risposte certe. Omeopatia ed elettromagnetismo potrebbero essere interpretate, alla luce del relativamente recente paradigma fisico quanto-elettrodinamico, come due facce della stessa moneta spendibile per soddisfare, in chiave sia teorica che sperimentale, le esigenze di complesse dinamiche biologiche in cerca di una propria riconoscibile e specifica identità. A tal proposito, i nostri campioni sono stati anche valutati geneticamente. Una migliore comprensione del meccanismo d’azione sia dei medicinali omeopatici che dei campi elettromagnetici deboli potrebbe essere raggiunta grazie all’uso di modelli in vitro e in vivo nei quali la correlazione trattamento/effetto è più diretta e quindi più facilmente interpretabile. Tra questi, i modelli vegetali presentano numerosi vantaggi come l’assenza di effetto placebo e di problemi etici, l’impiego di materiale biologico economico e pressoché inesauribile, la possibilità di condurre un elevato numero di prove in tempi ragionevolmente brevi e di poter quindi disporre di un’ampia base di dati per un’approfondita analisi statistica. Scopo della nostra ricerca è: i) fornire un contributo sperimentale per la valutazione degli effetti biologici delle alte diluizioni omeopatiche e di trattamenti elettromagnetici, mediante esperimenti standardizzati basati su modelli vegetali; ii) identificare un’eventuale similarità tra gli effetti biologici della potentizzazione omeopatica e dell’esposizione elettromagnetica. In particolare sono stati studiati un modello di germinazione in vitro del polline (Betti et al, Bioelectromagnetics, 2010, submitted) e un modello fitopatologico rappresentato dall’interazione tabacco/virus del mosaico del tabacco (Betti et al, Homeopathy, 2003; Trebbi et al, Bioelectromagnetics, 2007)
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
