Juventud negada y negativizada: Representaciones y formaciones discursivas vigentes en la Argentina contemporánea
Ultima década , 2005, DOI: 10.4067/S0718-22362005000200002
Abstract: this article delivers an analysis and description of the current representations and speeches regarding the contemporary young people of argentina. this representation was built based on the field job carried out with several actors (young people, old people, communications media) during years 1998 and 2004 in the city of la plata (province of buenos aires) as a part of the doctoral investigation of the authoress (chaves, 2005). the analysis of the speeches allowed the identification of several representations over the young as well as the acknowledgement of discursive formations in which such representations were included. the note includes as well a systematization of characterizations for the young people of argentina and/or latin america, carried out by other authors. as well, equivalencies are established with the offered proposal. finally, it is interpreted that the hegemonic visions towards the young people of latin america are due to the legislature juridic and restrictive model. it is said that the young people is known by the ?great no?, it is unfit (according to the juridic model) or negative (according to the restrictive model); the young are not allowed to exist as a total entity (in transition, uncomplete, nor infant nor grown up) or their practices are condemned (they are problematic youths, uncommitted, rebels or delinquents and offenders).
O trágico, o c?mico e a "distancia artística": arte e conhecimento n'A Gaia Ciência, de Nietzsche
Chaves, Ernani;
Kriterion: Revista de Filosofia , 2005, DOI: 10.1590/S0100-512X2005000200011
Abstract: this reading of the gay science intends to show some important elements which, in this book, gravitate around the theme of "distance". analysing particularly three aphorisms of the book, our goal is to clarify the movement, in the text and in nietzsche's thought as well, from distance as ferne, with its romantic source, to distance as distanz. however, in the end, we intend to show that nietzsche dislocates the romantic theme of the ferne, taking it as an "artistic distance", which becomes the distinctive trace between the perspectives of art and knowledge.
Dissec??o da artéria carótida

Revista Brasileira de Cardiologia Invasiva , 2008, DOI: 10.1590/S2179-83972008000300018
Abstract: carotid artery dissections usually have a good prognosis and should be thought as a potential etiology of stroke and transient ischemic attacks (tias) in young patients. noninvasive imaging techniques, in particular magnetic resonance imaging (mri) (t1- and t2-weighted, fat-suppressed t1) and magnetic resonance angiography (mra) of head and neck with and/or without gadolinium, should be used routinely for screening of patients with internal carotid artery (ica) dissection. computed tomographic angiography (cta) can be an alternative or adjunctive diagnostic technique used for evaluation of dissection. conventional angiography should be reserved for selected cases where the diagnosis remains indeterminate after initial studies have been performed. further studies are necessary to evaluate the best therapeutic options for patients with arterial dissection.
Mito e política: notas sobre o conceito de destino no "jovem" Benjamin
Chaves, Ernani;
Trans/Form/A??o , 1994, DOI: 10.1590/S0101-31731994000100002
Abstract: the concept of myth is one of the keys to understand the thought of walter benjamin. the aim of this paper is to follow its genesis from the first formulations of the concept of "destiny", as presented in destiny and character, written in 1919. the present paper is divided in two parts. the first reconstructs benjamin's arguments, showing them tobe within the domain of the theory of rights and their necessary insertion in a "temporality" mode, defined by "repetition"; the second part attempts to demonstrate that benjamin's positions were closely linked to a political stand: their aim was, in name of an avowed anarchism, to fight against all nationalist "myths" (that brought germany to war) and the need of "leaders" (führer) for the people. examples of this political bias, based on benjamin's confrontation with zionism, are presented.
Considera??es sobre o ator: uma introdu??o ao projeto nietzschiano da fisiologia da arte
Chaves, Ernani;
Trans/Form/A??o , 2007, DOI: 10.1590/S0101-31732007000100005
Abstract: together with the project of revaluation of all values, the schema of a "physiology of art" gains a central role in nietzsche's last writings. that's a perspective that supposes a defeat both of the "artist's metaphysics" of the initial period and of the critique of romanticism that characterizes a second moment. taking as a starting point the discussion about the pertinence of utilization of the term physiology in nietzsche's work, this article intends to present, in general terms, the reaching of this project to the discussion of the relations between art and truth, art and illusion. in conclusion, the intention here is to show the importance of this idea of a physiology of art taking as a reference the figure of the actor.

Abstract: Autorregressive integrated moving average models ARIMA, were adjusted to series of monthly sun bright for 32 meteorological stations of The National Federation of Coffee Growers of Colombia. The structure of the adjusted models was ARIMA(0; 1; 1) * (0; 1; 1)12 this is a moving average with a seasonality component each 12 month, the estimated parameters were sufficient to describe the behavior of the series, they were statistically different from zero and non correlated. The estimated forecasts were found very approximated to observed values, they are actualized monthly, this characteristic allow to readjust the model when the pattern series change and to plan activities related with absorption of solar energy. The greatest forecast error was 23% and it is considered acceptable. Se ajustaron modelos ARIMA a series mensuales de brillo solar obtenidas en 32 estaciones meteorológicas de la Federación Nacional de Cafeteros de Colombia. La estructura de los modelos ajustados fue ARIMA(0; 1; 1)*(0; 1; 1)12 de promedios móviles con componente estacional de 12 meses. Los parámetros estimados fueron suficientes para describir el comportamiento de la serie. Los pronósticos obtenidos fueron muy cercanos de los valores observados, actualizados mensualmente. Esta característica permite reajustar el modelo cuando haya cambios en el patrón de la serie y planificar actividades relacionadas con la absorción de la energía solar. El mayor error de pronóstico fue de 23 %, considerado como aceptable.
Juventud negada y negativizada: Representaciones y formaciones discursivas vigentes en la Argentina contemporánea
Mariana Chaves
Ultima Década , 2005,
Abstract: En este artículo se brinda una descripción y análisis de las representaciones y discursos vigentes acerca de las y los jóvenes en la Argentina urbana contemporánea. Esta caracterización fue construida con base al trabajo de campo con diversos actores (jóvenes, no-jóvenes, medios de comunicación) realizado entre los a os 1998 y 2004 en la ciudad de La Plata (Provincia de Buenos Aires, Argentina) como parte de la investigación doctoral de esta autora (Chaves, 2005). El análisis de los discursos permitió identificar diversas representaciones sobre la juventud y reconocer formaciones discursivas en las que dichas representaciones entraban en juego. El escrito ofrece también una sistematización de caracterizaciones realizadas por otros autores para la juventud argentina y/o la juventud latinoamericana y se establecen equivalencias con la propuesta realizada. Finalmente se interpreta que las miradas hegemónicas sobre la juventud latinoamericana responden a los modelos jurídico y represivo del poder. Se sostiene que la juventud está signada por el gran NO , es negada (modelo jurídico) o negativizada (modelo represivo), se le niega existencia como sujeto total (en transición, incompleto, ni ni o ni adulto) o se negativizan sus prácticas (juventud problema, juventud gris, joven desviado, tribu juvenil, ser rebelde, delincuente).
Reconciliation or Bust?
Elisabeth Chaves
Journal of Critical Globalisation Studies (JCGS) , 2012,
Abstract: Mainstream economics posits the economy as a disembedded sphere generally governed by its own rules and principles. In reality, the economy is comprised of social relations, and conflicting interests configure those relationships. As a result, our political economy is the outcome of that conflict, a reconciliation between democracy and capitalism, variously termed democratic capitalism, embedded liberalism, or the welfare state...
Modelo de rendimiento potencial del cultivo de plátano (Musa AAB Simmonds)
Chaves Bernardo
Agronomía Colombiana , 2009,
Abstract: El plátano es un producto básico en la alimentación para más de 400 millones de habitantes de las regiones tropicales y subtropicales del mundo. Los modelos del desarrollo de cultivos se han convertido en una herramienta de mucha utilidad para investigadores que estudian procesos fisiológicos básicos, y agricultores que los usan en la toma de decisiones para el manejo del cultivo. Con el objetivo de desarrollar un modelo de producción potencial de plátano, se usaron los datos de dos experimentos con la variedad Dominico-Hartón en Colombia, en los cuales se midieron variables fisiológicas de crecimiento y desarrollo, así como variables climáticas. Con base en los resultados se estimó el coeficiente de extinción de la luz (k) en 0,2817 y el uso eficiente de la luz (LUE) en 1,63 g MJ-1 . En la etapa vegetativa, las hojas, el tallo y el cormo incrementaron su materia seca por partes iguales, pero en la etapa reproductiva las hojas y el cormo perdieron masa, mientras que el tallo continuó en aumento, aunque no tan aceleradamente como en la primera etapa. Del análisis de sensibilidad se deduce que LUE es el parámetro más sensible y, por lo tanto, los esfuerzos se deben dirigir a mejorar la conversión de luz incidente en materia seca.
