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
A comparative study on distance-based inconsistency indices defined over Abelian linearly ordered groups
No full textPairwise comparisons have been a long-standing technique for comparing alternatives/criteria and their role has been pivotal in the development of modern decision-making methods. Pairwise comparisons can be performed within several theoretical frameworks such as multiplicative, additive and fuzzy preference systems, which are particular instances of a more general framework based on Abelian linearly ordered groups. Although, in this general algebraic framework, three distance-based inconsistency indices have been proposed, no comparative study has been conducted on them; thus, this paper aims at filling this gap. In particular, we look for relationships and functional relations between these inconsistency indices and whenever a functional relation does not exist, we analyze their correlation and determine the regression curve of an index on another one
Approcci e strumenti a supporto per la valutazione diagnostica delle piaghe da decubito e il rilievo delle aree geografiche con più elevata necessità di cure domiciliari
No full textIl capitolo descrive l’approccio ottimale sperimentato durante le attività di progetto finalizzato al rilievo della forma della piaga da decubito nell’immagine scattata al paziente. Esso è composto da tre fasi: una fase di compressione lossy dell’immagine basata sull’impiego della Fuzzy Transform bidimensionale, che permette di ridurre la complessità computazionale necessaria alla segmentazione delle immagini, una fase successiva in cui è impiegato un metodo ibrido di Fuzzy clustering per l’image segmentation e, una terza fase in cui è applicato il metodo di Canny con soglie di isteresi di image detection per il riconoscimento della forma della piaga.
Viene, inoltre, presentato un approccio basato su metodi decisionali multi-criterio per valutare contemporaneamente una molteplicità di aspetti, spesso tra loro contrastanti, sia nella classificazione e diagnosi delle piaghe del paziente che nella successiva personalizzazione del percorso terapeutico assistenziale. Allo scopo di ottimizzare i tempi di guarigione, differenti aspetti, quali ad esempio costi, qualità della vita del paziente e numero di accesi in cure domiciliari, possono essere valutati.
Infine, sono mostrati i risultati di uno studio svolto sull’intero territorio campano della distribuzione e della concentrazione di popolazione residente anziana, maggiormente soggetta al fenomeno delle piaghe da decubito. Tale studio è successivamente focalizzato sui cinque capoluoghi e sui centri urbani più densi per analizzare la presenza di aree urbane dove è maggiormente o massicciamente presente popolazione di fascia di età anziana con condizioni peggiorative legate ad elevato impatto all’ondata di calore, al fine di rilevare le zone maggiormente colpite dalla malattia e in cui è necessario un maggior presidio medico una maggiore frequenza di cure domiciliari
