MINI-PERCUTANEOUS PROCEDURE (MIPP): A NEW SET
No full textWe are presenting our instrumental set for mini-percutaneous procedure (MIPP-set), manufactered in collaboration with RUSCH Medical Company, along with our indications and clinical experience.From January 2002 to December 2006, we treated with MIPP 63 patients. The procedures stone-free rate was 98,3%. The limits of this technique are: major operation times and consequently major costs; more difficulties in vision and operability. The advantages are: less trauma, reduction of bleeding, possibility of tubeless procedures and shorter recovery times. Supine position is certainly a step forward in terms of reducing operative times and percentage of clearance of the fragments. The progress mainly in optics and the miniaturization of instruments will make the procedure more useful and effective
LA MINI-PERCUTANEA IN POSISZIONE SUPINA: SOLO VANTAGGI ?
No full textLa minipercutanea in decubito prono è ormai
una metodica consolidata per la maggior parte
degli Endourologi. La posizione supina, alla
luce della nostra esperienza offre numerosi
vantaggi. ll paziente può posizionarsi da solo
nel decubito ottimale evitando rischi di posture
viziate serrza compromettere l’ intubazione
anestesiologica. Il cateterismo ureterale è agevolmente
eseguito sollevando solamente l'arto
inferiore controlaterale; non è quindi necessario
variare il decubito del paziente anestetizzato,
manovra alquanto problematica in pazienti
obesi o di grossa taglia. II decubito supino
non provoca compressione sul torace rendendo
quindi possibile l'utilizzo della metodica
percutanea anche in pazienti con gravi deficit
respiratori o nei grandi obesi. L’accesso transcolico,
complicanza rara ma possibile risulta
più improbabile in quanto in tale decubito si
verifica un aumento dello spazio rene-colon
come documentato da valutazione TC nei due
decubiti. Il contemporaneo dominio della via
escretrice, retrograda ureteroscopica ed anterograda
percutanea con strumenti rigidi e flessibili
rende possibile la completa clearance
litiasica anche in casi particolarmente complessi.
L’irrigazione attraverso il cateterino ureterale
rende agevole la fuoriuscita per gravità
dei frammenti litiasici residui dopo la trissia
laser diminuendo inoltre il tempo operatorio.
In considerazione di tali vantaggi riteniamo
che il decubito supino sia attualmente da considerarsi
auspicabile nella percutanea standard
ed ottimale nella minipercutanea
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
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
