Clínica Médica; ArgentinaLa prevalencia de Insuficiencia Cardíaca (IC) está en aumento debido al envejecimiento
de la población, la supervivencia de eventos coronarios agudos y la eficacia en la prevención de los
mismos. Afecta a un 2-3% de los individuos, aumentando a un 10-20% en pacientes que se encuentran entre 70 y 80 años. La edad promedio es de 75 años. Las etiologías más frecuentes son el daño
miocárdico agudo (70%), el aumento de la resistencia períferica con HTA y las taquiarritmias. Los
pacientes con IC pueden presentar empeoramiento de la función renal siendo éste un predictor independiente de mal pronóstico. En pacientes internados por cuadros de Insuficiencia Cardíaca Aguda
Descompensada (ICAD) el daño renal se asocia a hospitalizaciones más prolongadas, aumento de la
mortalidad y reingresos en el primer año.Fil: Otaduy, Cintia. Hospital Córdoba. Clínica Reumatológica; ArgentinaFil: Bosio, Luis. Hospital Córdoba. Infectología; ArgentinaFil: De la Vega, Marcos.

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
An experimental approach to the study of interpersonal violence in Northeastern Patagonia (Argentina), during the late Holocene
Get PDFThis paper incorporates an experimental approach to the study of violence patterns in Northeastern Patagonia (Argentina) during the late Holocene. The underlying hypothesis considers a close association between socio-ecologic alterations during the Medieval Climatic Anomaly (MCA) (ca. 1150-600 years BP; Stine, 1994, 2000) and a probable increase in conflict levels. In order to test this hypothesis, human skulls (n = 986) were analyzed for bone lesions, discriminating late bone lesions, such as those produced by metal tools. The experimental approach used swine (Sus scrofa domestica) skulls, as proxies for human skulls, and incorporated original sabers. From this discriminating analysis, it can be inferred that no significant increase in violence signs were recorded until the first stages of Hispanic-indigenous contact (first half of 17th century). These findings emphasize the need for a revision of the implications of the dynamics of human populations in Northeastern Patagonia during the late Holocene.Fil: Gordón, Florencia.

Evidencias de trauma en el periodo formativo en el valle de San Francisco, Jujuy, Argentina
Get PDFLas sociedades que vivieron durante el Período Formativo en el noroeste de Argentina, fueron interpretadas como grupos sin diferencias sociales estructurales y con relaciones de interacción entre sí. Esto configura un escenario con ausencia de conflictividad social lo cual se vería reflejado en el registro arqueológico. En este trabajo se presenta el caso de dos individuos procedentes de la región piedemontana de las Yungas de Jujuy, Argentina con cronologías que los adscriben al Período Formativo (800 aC-500 dC), con evidencias de lesiones vitales en el cráneo las cuales dan cuenta de la presencia de violencia interpersonal entre los grupos tradicionalmente denominados San Francisco.Societies that lived during the Formative period in northwestern Argentina, have been interpreted as groups without social structural differences and with relations of interaction with each other. This sets up a scenario without social conflict, which would be reflected in the archaeological record. This paper presents the case of two individuals from the region of the Yungas pedemontanas of Jujuy, Argentina, with chronologies that ascribe the Formative Period (800 BC – 500 AD), with evidence of skull injuries which account the presence of interpersonal violence among groups traditionally called “San Francisco”.Fil: Ortiz, Gabriela del Carmen.

Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
