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
Efficacia della combinazione xilazina-tiletamina-zolazepam e azaperone per il contenimento farmacologico del cervo sardo (Cervus elaphus corsicanus)
No full textIl cervo sardo (Cervus elaphus corsicanus) è un ungulato selvatico di media taglia,
endemico in Sardegna ed appartenente alle specie rare (lista rossa delle specie minacciate IUCN).
Ventisette esemplari di cervo sardo sono stati catturati con teleanestesia durante un programma di
reintroduzione usando una combinazione di tiletamina e zolazepam con xilazina nota con la
denominazione di “wiener mischung”. I dosaggi medi ± DS sono stati 1.0±0.1 ml/capo pari a
(1.6±0.1 mg/Kg) per le femmine e 1.2±0.2 ml/capo pari a (1.2±0.2 mg/Kg) per i maschi. Terminate
le operazioni, dopo 38±6 minuti, cinque cervi individuati in modo random (4 femmine e 1
maschio), hanno ricevuto azaperone EV alla dose di 0.5 mg/Kg. Prima del trasporto, in tutti i
soggetti è stato somministrato atipamezolo IM 0.13 mg/Kg. L’uso della “wiener mischung” è
sembrata adeguata per l’immobilizzazione chimica sul campo del cervo sardo, soprattutto per il
breve tempo di induzione, il volume ridotto e l’ampio margine di sicurezza. I risultati ottenuti
supportano l’idoneità dell’uso dell’azaperone nelle operazioni di cattura del cervo sardo per ridurre
lo stress, prevenire i danni da trasporto e migliorare la qualità della rimessa in libertà.Sardinian deer (Cervus elaphus corsicanus) is a medium-size wild ungulate, endemic
in Sardinia, catalogued as a rare species (IUCN Red list of Threatened Species). Twenty-seven
sardinian deer were captured with teleanaesthesia in the course of a restocking programme using the
combination of tiletamine HCl and zolazepam HCl with xilazine known as “wiener mischung”.
Mean± SD dosages were 1.0±0.1ml (1.6±0.1 mg/Kg) for females and 1.2±0.2 ml (1.2±0.2 mg/Kg)
for males. At the end of the operations, after 38±6 minutes, five deer randomly selected (4
females,1 male) were injected with azaperone EV 0.5 mg/Kg. Before transport, in all deer was
injected atipamezole IM 0.13±0.01 mg/Kg. The use of the so called “wiener mischung” seems
adequate for chemical immobilization of sardinian deer under field conditions, mainly because of
its short induction time, small volume to be darted and wide safety margin. The results obtained
support the suitability of the use of azaperone in capture of sardinian deer in order to reduce stress
response, to prevent damages of transport and to better the quality of release operations
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
Valutazioni cliniche ed anatomopatologiche riferibili a stress durante la cattura ed il trasporto del cervo sardo (Cervus elaphus corsicanus)
No full textLa cattura del cervo, che solitamente viene effettuata a scopo di trasferimento per reintroduzioni in areali vocati, costituisce uno stress di notevole entità, anche se viene effettuata in teleanestesia. Una combinazione anestetica di xilazina, tiletamina e zolazepam è stata utilizzata per la cattura di 10 soggetti nel periodo Novembre 2009 - Febbraio 2010 in Sardegna. Dopo 30 minuti di anestesia, terminate le operazioni programmate, la xilazina è stata antagonizzata con atipamezolo in tutti i soggetti. Per la successiva fase di trasporto e liberazione, nella metà dei soggetti è stato somministrato azaperone 0,5 mg/kg. In questo gruppo la fase di liberazione è stata calma mentre è stata agitata nellì'altro gruppo, nel quale si è verificato un decesso a distanza di 16 ore. La somministrazione di un tranquillante dopo l'antagonizzazione della xilazina può ridurre le patologie da stress da cattura
