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
Problemática ecológico-política de la ciudad de Ushuaia en el período 1991-2011: un análisis de las relaciones de poder en perspectiva a la viabilidad comunal
Full text linkUshuaia, ciudad fundada por el comodoro Augusto Lasserre el 12 de octubre de 1884,
es una orbe cuya vida social, política y económica fue desde sus comienzos y es en la
actualidad fuertemente impactada por la intervención activa del Estado nacional.
Situada en la margen sur de la isla Grande de Tierra del Fuego, a más de 3 mil
kilómetros de la capital argentina, y poseedora de un clima hostil y una topografía que
no favorece la instalación de asentamientos humanos, la capital fueguina debe su
existencia y su volumen poblacional fundamentalmente a la disputa de nuestro país con
la República de Chile por la soberanía sobre la región.
El origen eminentemente político de la ciudad, la forma en que se implementaron las
políticas de fomento de la población y la motivación de los migrantes para radicarse en
la región conformaron una sociedad ushuaiense cuya dinámica social, política, cultural
y económica gestó una situación ecológico-política preocupante, que aleja a Ushuaia del
horizonte de la viabilidad comunal.
En el presente trabajo se da cuenta tanto de la situación ecológico-política generada,
acotando el período de estudio al lapso de tiempo comprendido entre los años 1991-2011, como de las relaciones de poder político subyacentes a la gestación de dicha
situación; habiéndose realizado el estudio desde la perspectiva de la ecología política, y
considerando en el mismo la complejidad intrínseca a los hechos sociales, los que
fueron analizados en forma holística y multimodal con vistas a brindar elementos útiles
para la concepción de políticas públicas orientadas a preservar la viabilidad comunalUshuaia, founded by Commodore Augusto Lasserre on October 12th, 1884, is a city
whose social, political and economic life has, from its beginnings to this day, been
strongly affected by the active intervention of the national State.
Located on the south bank of the Isla Grande de Tierra del Fuego over three thousand
kilometres away from the capital of Argentina and having a hostile climate and a
topography which do not favour the establishment of human settlements, the capital of
Tierra del Fuego owes its existence and population density mainly to the dispute
between our country and the Republic of Chile about the sovereignty over the region.
The eminently political origin of the city, the way in which settlement policies are
implemented and the immigrants' motivation for settling in the region have shaped an
Ushuanian society whose social, political, cultural and economic dynamics has bred a
worrying ecological-political situation which keeps Ushuaia away from the horizon of
urban feasibility.
This paper recounts both the ecological-political situation generated and the political
power relationships underlying the gestation of said situation (the period under study
has been limited to the time elapsed between the years 1991 and 2011). This study has
been performed from the ecological-political perspective and has considered the
inherent complexity of social events, which were analysed on the basis of a holistic and
multi-modal approach with a view to providing useful elements for the conception of
public policies aiming at preserving urban feasibilityFil: Chiari, Mario E. Universidad Nacional de Tierra del Fuego; Argentina
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
Identification and characterization of Fringilla coelebs Papillomavirus 1 (FcPV1) in free-living and captive birds in Italy
No full textA papillomavirus (PV) was identified by negative-staining electron microscopy in skin lesions of two bird species (Fringillidae) in Italy. Genetic analyses revealed an FcPV1 with a low genetic variability in the E6, E7, E1, E2, and L1 genes and the long control region when compared to the FcPV1 reference strain
