La apariencia estética como el aparecer del demos: política(s) y estética(s) de la democracia en la propuesta de Juliane Rebentisch; The aesthetic appearance as the demos appear: Politics and aesthetic of the democracy in the proposal of Juliane Rebentisch Cristobo, Matias La Teoría Crítica ligada a la tradición del Instituto de Investigación Social de Frankfurt ha sido frecuentemente periodizada teniendo en cuenta las sucesivas generaciones de pensadores que la animaron. Desde este recorte temporal, la llamada “tercera generación” de la Teoría Crítica renovó sus principales líneas de investigación incorporando a la tradición alemana de pensamiento los desarrollos del posestructuralismo francés. En esta misma dirección, una representante de la “cuarta generación”, Juliane Rebentisch, encuentra en las teorías de Claude Lefort y Jacques Rancière nuevas formas de abordar problemas propios del idealismo alemán, tal como el de la apariencia estética, en su vínculo siempre conflictivo con la política. El objetivo de nuestro trabajo es desentrañar la tesis central de Rebentisch en lo que concierne a su reinterpretación de la estetización de la política.; Critical Theory linked to the tradition of the Institute for Social Research in Frankfurt has often been timed considering successive generations of thinkers who encouraged her. From this temporary cut, the so-called “third generation” of Critical Theory renewed its main research incorporating the German tradition of thinking developments of French post-structuralism. In the same direction, a representative of the “fourth generation”, Juliane Rebentisch, finds in the theories of Claude Lefort and Jacques Rancière new ways of addressing problems of the German idealism, such as aesthetic appearance and its always difficult link with politics. The objective of our work is to unravel the central thesis of Rebentisch regarding his reinterpretation of the aestheticization of politics.

Escritura académica, argumentación y prácticas de enseñanza en el primer año universitario; Academic Writing, Argumentation and Teaching Practices in the First Year of Higher Education Molina, Maria Elena Este artículo muestra cómo docentes de la carrera de Profesorado y Licenciatura en Letras de una universidad pública argentina lograron entramar prácticas de escritura académica con prácticas de enseñanza, a fin de actualizar en sus aulas los potenciales epis- témicos de la escritura. Enmarcados en un estudio de casos múltiples, configurado como una investigación didáctica naturalista, los resultados expuestos aquí provienen de dos fuentes de datos: entrevistas a alumnos y recolección de materiales de trabajo (con- signas de escritura y producciones de alumnos). El análisis de tales datos estuvo guiado por la codificación y la contextualización, buscando las relaciones de similitud y contigüidad entre ellos. Desde el punto de vista teórico, teniendo como antecedentes los estudios sobre escribir a través del currículum (WAC), esta investigación retoma la noción de transposición didáctica propuesta por Chevallard para caracterizar de qué formas se entraman prácticas de enseñanza con escritura, en particular, cuando los docentes trabajan en sus clases una práctica de escritura disciplinar. Así, hallamos que, para transponer en el aula prácticas de escritura que resultasen potencialmente epistémicas y no propedéuticas, los docentes precisaron trabajar con una escritura argumentativa y vigilar cuidadosamente que las circunstancias de producción de tales prácticas fuesen similares a las que se desarrollan en el ámbito de las comunidades disciplinares a las que aspiran a pertenecer sus alumnos.; This article shows how teachers of the career of Linguistics and Literature, form an Argentine public university, intertwine teaching and writing practices to work in their classrooms with the epistemic potential of writing. From a multiple case study configured as a naturalist didactic research, this inquiry works with two kinds of data: interviews with students and collection of documents (writing assignments and texts produced by students). The strategies of coding and contextualization guided to data analysis, paying attention to the relations of similarity and contiguity between them. From the theoretical point of view, having the studies on writing across the curriculum (WAC) as background, this research returns to the notion of didactic transposition proposed by Chevallard. This notion allows us to explore how the teachers intertwine teaching and writing practices by working in their classes with a disciplinary writing practice. Thus, we found that to bring into the classroom a writing practice that would potentially become epistemic and not preparatory (i.e., as a simple exercise for the future), teachers needed to work with argumentative writing and to carefully check the production circumstances of such practices. These circumstances are similar to the ones developed within the disciplinary communities to which the students were aspiring to belong.

Una aproximación a la participación política femenina: entre los Centros Cívicos y la primera constitución del Partido Peronista Femenino (Córdoba, 1946-1949) Spinetta, Marina Ines en el presente trabajo se aborda la participación política femenina alentada por el peronismo cordobés, desde comienzos de 1946 con el surgimiento de los llamados Centros Cívicos o Centros Peronistas Femeninos, hasta la constitución primaria del Partido Peronista Femenino en Córdoba, tarea delegada en la primera dama provincial, Leonor Leiva Castro de San Martín, entre mediados de 1948 y fines de 1949, momento en que se asiste a la reestructuración del movimiento con la llegada de la delegada censista.; In this study women’s political participation encouraged by the Cordovan Peronism addressed, since the beginning of 1946 with the emergence of so-called civic centers or centers Female Peronist until the primary constitution of Female Peronist Party in Cordoba, a task delegated to the First Lady provincial, Leonor Castro Leiva San Martín, between mid-1948 and late 1949, time to witness the arrival of the delegates enumerators and restructuring of the movement.

Effect of pre and postharvest application of fungicides on postharvest decay of Bosc pear caused by Alternaria—Cladosporium complex in North Patagonia, Argentina Lutz, María Cecilia; Sosa, María Cristina; Colodner, Adrian D. In recent years, decays by Alternaria spp. and Cladosporium spp. constituted a hazard to “Bosc” pear fruit during cold storage with significant economic losses (about 50%) in the Rio Negro and Neuquen Valleys. Studies with new fungicides that potentially have good activity against these key pathogens of “Bosc” pears were carried out. During the years 2011, 2012 and 2013, commercial formulations of pyraclostrobin + boscalid (Pyr + Bosc), cyprodinil + fludioxonil (Cyp + Flu), fludioxonil (Flu), pyrimetanil (PyrM) and myclobutanil (Myc) were studied by in vitro and in vivo tests. Commercial formulations of Flu, PyrM and Myc were added to the study to be used and have a use register for pome fruits in Argentina. In vivo tests were applied postharvest on laboratory and semicommercial scale, and, preharvest, to orchard. In vitro tests showed high percentages of inhibition of mycelial growth and conidia germination of both Alternaria and Cladosporium, however Flu was highlighted in the inhibition of Alternaria (EC50 = 0.0014) and Pyr + Bosc to Cladosporium (EC50 = 1.14 × 10−8 ). In vivo assays on semi-commercial scale, showed that fungicides evaluated (Pyr + Bosc, Cyp + Flu, Flu and Pyr) applied postharvest only reduced the natural incidence of Alternaria-Cladosporium complex (4 months at −1/0 °C), between 24 and 35%, while on wounds artificially inoculated, the reduction achieved was between 91 and 98%. These results suggest that for the control of Alternaria-Cladosporium complex in Bosc pears, postharvest interventions are insufficient. In this sense, the results obtained of preharvest application of Pyr + Bosc showed that the control of the incidence of this decay after 4 months of cold storage was 44.6% of Alternaria-Cladosporium and 95% of B. cinerea. The results of this study indicate that preharvest applications, with the fungicide Pyr + Bosc, reduce the incidence of decay in postharvest, so this might be an important strategy to reduce postharvest losses in the irrigated valleys of Rio Negro y Neuquen.

Nitrogen-fixing rhizobial strains isolated from Desmodium incanum DC in Argentina: Phylogeny, biodiversity and symbiotic ability Toniutti, Maria Antonieta; Fornasero, Laura Viviana; Albicoro, Francisco Javier; Martini, María Carla; Draghi, Walter Omar; Alvarez, Florencia; Lagares, Antonio; Pensiero, Jose Francisco; del Papa, Maria Florencia Desmodium spp. are leguminous plants belonging to the tribe Desmodieae of the subfamily Papilionoideae. They are widely distributed in temperated and subtropical regions and are used as forage plants, for biological control, and in traditional folk medicine. The genus includes pioneer species that resist the xerothermic environment and grow in arid, barren sites. Desmodium species that form nitrogen-fixing symbiosis with rhizobia play an important role in sustainable agriculture. In Argentina, 23 native species of this genus have been found, including Desmodium incanum. In this study, a total of 64 D. incanum-nodulating rhizobia were obtained from root nodules of four Argentinean plant populations. Rhizobia showed different abiotic-stress tolerances and a remarkable genetic diversity using PCR fingerprinting, with more than 30 different amplification profiles. None of the isolates were found at more than one site, thus indicating a high level of rhizobial diversity associated with D. incanum in Argentinean soils. In selected isolates, 16S rDNA sequencing and whole-cell extract MALDI TOF analysis revealed the presence of isolates related to Bradyrhizobium elkanii, Bradyrhizobium japonicum, Bradyrhizobium yuanmingense, Bradyrhizobium liaoningense, Bradyrhizobium denitrificans and Rhizobium tropici species. In addition, the nodC gene studied in the selected isolates showed different allelic variants.Isolates were phenotypically characterized by assaying their growth under different abiotic stresses. Some of the local isolates were remarkably tolerant to high temperatures, extreme pH and salinity, which are all stressors commonly found in Argentinean soils. One of the isolates showed high tolerance to temperature and extreme pH, and produced higher aerial plant dry weights compared to other inoculated treatments. These results indicated that local isolates could be efficiently used for D. incanum inoculation.

Neural network-based state estimation for a closed-loop control strategy applied to a fed-batch bioreactor Rómoli, Santiago; Serrano, Mario Emanuel; Rossomando, Francisco Guido; Vega, Jorge Ruben; Ortiz, Oscar; Scaglia, Gustavo Juan Eduardo The lack of online information on some bioprocess variables and the presence of model and parametric uncertainties pose significant challenges to the design of efficient closed-loop control strategies. To address this issue, this work proposes an online state estimator based on a Radial Basis Function (RBF) neural network that operates in closed loop together with a control law derived on a linear algebra-based design strategy. The proposed methodology is applied to a class of nonlinear systems with three types of uncertainties: (i) time-varying parameters, (ii) uncertain nonlinearities, and (iii) unmodeled dynamics. To reduce the effect of uncertainties on the bioreactor, some integrators of the tracking error are introduced, which in turn allow the derivation of the proper control actions. This new control scheme guarantees that all signals are uniformly and ultimately bounded, and the tracking error converges to small values. The effectiveness of the proposed approach is illustrated on the basis of simulated experiments on a fed-batch bioreactor, and its performance is compared with two controllers available in the literature.

Inflation expectations, learning, and supermarket prices: Evidence from survey experiments Cavallo, Alberto; Cruces, Guillermo Antonio; Perez Truglia, Ricardo Information frictions play a central role in the formation of household inflation expectations, but there is no consensus about their origins. We address this question with novel evidence from survey experiments. We document two main findings. First, individuals in low inflation contexts have significantly weaker priors about the inflation rate. This finding suggests that rational inattention may be an important source of information frictions. Second, cognitive limitations also appear to be a source of information frictions: Even when information about inflation statistics is available, individuals still place a significant weight on inaccurate sources of information, such as their memories of the price changes of the supermarket products they purchase. We discuss the implications of these findings for macroeconomic models and policymaking.

A Dead Time Compensator Based on Linear Algebra (DTCLA) Camacho, Oscar; Scaglia, Gustavo Juan Eduardo; Quintero, Lucia O. This paper proposes a dead time compensator based on a combination of the linear algebra control methodology (proposed by Scaglia, 2009) and an internal model structure (Smith predictor), to solve elevated dead time system problems. Moreover, the process transfer function of the nonlinear system linearized at some operation point is approximated by a second order plus dead time transfer function. The controller performance is judged by simulations and it is evaluated using the ISE performance index. We compared this approach against a typical DTC-PID controller with improved results.

¿Una temática "en boga" o un problema silencioso? Primeras reflexiones sobre el abordaje etnográfico de una problemática socio-ambiental en una localidad rural (Córdoba, Argentina); A theme in vogue or a silent problem? First reflections on the ethnographic approach of a socio-environmental problem in a rural town (Córdoba, Argentina); Uma temática “em voga” ou um problema silencioso? Primeiras reflexões sobre a abordagem etnográfica de uma problemática socioambiental numa localidade rural (Córdoba, Argentina) Caisso, Lucía Este artículo presenta algunos puntos de reflexión surgidos de los inicios de una investigación etnográfica que busca abordar el modo en que inciden las transformaciones estructurales del agro pampeano en la vida cotidiana de una localidad rural del centro-norte cordobés. Específicamente, se interesa por explorar la politicidad existente en torno de la problemática de las fumigaciones con agrotóxicos y su asociación con distintas patologías, y los desafíos que presenta el trabajo de campo en este universo social y a propósito de esta temática. En un recorrido que nos invita a reconocer como "problema silencioso" aquello que concebimos inicialmente como "temática en boga", volvemos a una de las cuestiones centrales de toda antropología: la distancia existente entre el mundo social y los supuestos que poseemos sobre él quienes lo investigamos.; This article presents some reflection points arisen from the beginnings of an ethnographic investigation that tries to tackle the way in which the structural transformations of the Pampean agricultural space influence in the daily life of a rural town of the central northern of Cordoba. Specifically, it is interested in exploring the existing political character around the problems of fumiga-tions with agro-toxics and their association with different pathologies, and the challenges presented in the fieldwork in this social universe and in relation to this subject. In a journey that invites us to recognize as “silent problem” what we initially conceived as a “theme in vogue”, we return to one of the central questions of all Anthropology: the existing distance between the social world and the assumptions we, investigators, make about it.; Este artigo apresenta alguns pontos de reflexão surgidos aos inícios de uma pesquisa etnográfica que procura abordar o modo em que as transformações estruturais do espaço agrícola pampeano incidem na vida cotidiana de uma localidade rural do centro-norte de Córdoba. Especificamente, se interessa por explorar o aspecto político em torno à problemática das fumigações com agro-tóxicos e sua associação com distintas patologias, e os desafios que o trabalho de campo apresenta neste universo social a propósito desta temática. Em um caminho que nos convida a reconhecer como “problema silencioso” aquilo que concebemos inicialmente como “temática em voga”, voltamos a uma questão central de toda a Antropologia: a distância existente entre o mundo social e os supostos que os pesquisadores possuímos sobre o sujeito.

Politizando la escena ética. La lectura butleriana de la propuesta levinasiana; Politicizing the ethical scene. The butlerian reading of the levinasian proposal Canseco, Alberto Edmundo Fabricio Luego de la caída de las Torres Gemelas, Judith Butler procuró responder al nuevo contexto político a través de una serie de reflexiones filosóficas. Éstas estaban orientadas principalmente a la formulación de una crítica judía pos-sionista de las políticas de guerra contemporáneas y de los supuestos ontológicos de corte liberal que las sostenían. Este intento la obligó a revisar autor*s que no habían sido estudiad*s en sus teorizaciones anteriores. En este artículo, quisiera detenerme en una de esas revisiones, aquella que se refiere a la propuesta ética de Emmanuel Levinas. A propósito de la especificidad de esta recepción, quisiera sostener que Butler asume el planteo de Levinas, entendiendo, sin embargo, que es necesario politizar la escena ética y esta operación es llevada adelante a través de una vuelta a la filosofía de G.W.F. Hegel.

Arm and interarm abundance gradients in CALIFA spiral galaxies Sánchez-Menguiano, L.; Sánchez, S. F.; Pérez, I.; Debattista, V. P.; Ruiz-Lara, T.; Florido, E.; Cavichia, O.; Galbany, L.; Marino, R. A.; Mast, Damian; Sánchez-Blázquez, P.; Méndez-Abreu, J.; De Lorenzo-Cáceres, A.; Catalán-Torrecilla, C.; Cano-Díaz, M.; Márquez, I.; McIntosh, D.H.; Ascasibar, Y.; García-Benito, R.; Gónzalez Delgado, R. M.; Kehrig, C.; López-Sánchez, Á.R.; Mollá, M.; Bland-Hawthorn, J.; Walcher, C. J.; Costantin, L. Spiral arms are the most singular features in disc galaxies. These structures can exhibit different patterns, namely grand design and flocculent arms, with easily distinguishable characteristics. However, their origin and the mechanisms shaping them are unclear. The overall role of spirals in the chemical evolution of disc galaxies is another unsolved question. In particular, it has not been fully explored if the H ii regions of spiral arms present different properties from those located in the interarm regions. Here we analyse the radial oxygen abundance gradient of the arm and interarm star forming regions of 63 face-on spiral galaxies using CALIFA Integral Field Spectroscopy data. We focus the analysis on three characteristic parameters of the profile: slope, zero-point, and scatter. The sample is morphologically separated into flocculent versus grand design spirals and barred versus unbarred galaxies. We find subtle but statistically significant differences betweenthe arm and interarm distributions for flocculent galaxies, suggesting that the mechanisms generating the spiral structure in these galaxies may be different to those producing grand design systems, for which no significant differences are found. We also find small differences in barred galaxies, not observed in unbarred systems, hinting that bars may affect the chemical distribution of these galaxies but not strongly enough as to be reflected in the overall abundance distribution. In light of these results, we propose bars and flocculent structure as two distinct mechanisms inducing differences in the abundance distribution between arm and interarm star forming regions.

El protocolo de actuación para el funcionamiento de los convenios de sustracción internacional de niños y el código procesal civil y comercial de la provincia de Santa Fe Feuillade, Milton César En la reunión anual de la Comisión Nacional de Acceso a Justicia, realizada el 28 de abril de 2017 fue aprobado el Protocolo de Actuación para el funcionamiento de los Convenios de sustracción internacional de niños. Lo que queda pendiente es el antecedente jurisprudencial de la CSJN1 a fines de 2016 donde se establecía la necesidad que el poder legislativo dicte una ley reguladora del procedimiento interno que cumpla con las finalidades de las Convenciones de las que Argentina es parte en la materia, así como la aplicación del art. 2642 del Código Civil y Comercial en los casos de situaciones en los que no hay Tratado con un Estado. Se han presentado proyectos que perdieron estado parlamentario2 y actualmente hay proyectos que deberían ser tratados3 . Remarcamos la importante labor de grupos de investigación con propuestas que se desarrollan en la Universidad de Buenos Aires en conjunto con el Delegado para Latinoamérica de la Conferencia de la Haya.

Crítica de la figura del Protágoras en el libro IV de la Metafísica de Aristóteles; Critique of the Figure of Protagoras in Book IV of Aristotle’s Metaphysics Tabakian, Diego Alejandro En su defensa del Principio de no-contradicción (PNC) (Metaph. Γ. 4-6 y 8), Aristóteles discute con varios interlocutores, desde los presocráticos hasta el sofista Protágoras, ampliamente conocido en la Antigüedad por trastocar el concepto de verdad (ἀλήθεια) con su doctrina de la "homo mensura", declarando la imposibilidad del discurso falso. Consideramos que una lectura atenta del Libro Γ que rescate la figura del abderita puede mostrar cómo la crítica del sofista es clave para la constitución del pensamiento aristotélico en torno al problema de la verdad. En la primer sección (§1), expondré algunas consideraciones sobre el PNC que son relevantes para entender las motivaciones detrás de las críticas aristotélicas al sofista. A continuación (§2), analizaré dos de los argumentos aristotélicos contra los adversarios que discuten de mala fe: la "refutación" de Metaph. Γ. 4 y el "argumento de las apariencias contrarias" de Metaph. Γ. 5. Mi hipótesis es que algunos elementos teóricos esbozados en Γ. 4 permiten reconstruir una crítica aristotélica seria contra Protágoras en Γ. 5. Finalmente (§3) expondré una síntesis del camino recorrido y ofreceré algunas conclusiones.; .When positing the principle of non-contradiction (PNC) (Metaph. Γ. 4-6 & 8), Aristotle discusses with a number of interlocutors, from the Pre-Socratics to Protagoras, being the latter well-known in Antiquity for subverting the concept of truth (ἀλήθεια) with his doctrine of the “homo mesura”, stating the impossibility of false discourse. I think that a careful reading of Book Γ that rescues the figure of the Abderite could show how the critique of the Sophist would be the key when developing the Aristotelian thought on the question of truth. In the first section (§1) I shall offer some considerations concerning the PNC that are relevant in order to understand the motivations underlying the Aristotelian critique against this sophist. Next (§2) I shall analyze two Aristotelian arguments against those adversaries who discuss in bad faith: on the one hand, the “refutation” in Metaph. Γ. 4 and, on the other hand, the “argument of the contrary appearances” in Metaph. Γ. 5. My hypothesis is that some of the theoretical arguments sketched in Γ. 4 allow us to reconstruct a serious Aristotelian critique against Protagoras in Γ. 5. Finally (§3) I shall present a synthesis of the path traced within the article and offer some conclusions.

Las disputas por los territorios en los albores del Estado nación: la frontera oriental de Corrientes durante la segunda mitad del siglo XIX; Territorial Disputes at The Dawn of The Nation State: The Eastern Border of Corrientes During The Second Half of the Nineteenth Century; Disputas sobre territórios na aurora do Estadonação: a fronteira oriental de Corrientes durante a segunda metade do século XIX Bressan, Raquel Valeria La organización del Estado nacional argentino implicó una significativa transformación de la forma en que los Estados provinciales habían configurado su territorio durante la primera mitad de siglo XIX a partir de la existencia de fronteras abiertas. Este artículo tiene como objetivo reconstruir las distintas posturas y argumentos que se pusieron en juego y que delinearon la definición de la configuración territorial de la provincia de Corrientes durante la segunda mitad del siglo XIX. Si bien las dirigencias correntinas no alcanzaron sus anhelos de incorporar la región de las Misiones bajo la jurisdicción provincial, el análisis de diversas fuentes permite evidenciar los puntos de tensión con respecto a cuál era la mejor forma de desarrollo para los territorios fronterizos y, a su vez, cómo el Congreso nacional se constituyó en un ámbito privilegiado para arbitrar las heterogéneas posturas políticas y determinar pautas de acción para los espacios disputados.; The construction of the Argentine state unfolded within a political environment where provincial boundaries were formulated out of largely open frontiers. This paper seeks to explore this situation for the case of Corrientes and it rebuilt different positions and arguments about how boundaries must be defined during the second half past of 19th century, a period in which the province struggled (and failed) to incorporate the Missions territory under its jurisdiction. The analysis of various approaches to this questions permits a broader understanding of how Argentine politicians hoped to develop borderland spaces in more general terms and how the national Congress sometimes acted as referee or mediator among contending factions.; A organização do Estado nacional argentino implicou uma significativa transformação na forma em que os Estados provinciais haviam configurado seu território durante a primeira metade do século XIX, a partir da existência de fronteiras abertas. Este artigo pretende reconstruir as distintas posturas e argumentos que se colocaram e que delinearam a definição da configuração territorial da província de Corrientes durante a segunda metade do século XIX. Ainda que as diligências de Corrientes não alcançaram seus anseios de incorporar a região das Misiones sob a jurisdição provincial, a análise de diversas fontes permite evidenciar os pontos de tensão com respeito a qual era a melhor forma de desenvolvimento para os territórios fronteiriços e como o Congresso Nacional se constituiu em um âmbito privilegiado para arbitrar as posturas políticas heterogêneas e determinar pautas de ação para os espaços disputados.

Frente el autoritarismo, la creación: La experiencia de AIDA y su relectura en el film El Exilio de Gardel (Fernando Solanas, Francia / Argentina, 1985) Cristiá, Moira Inés En octubre de 1979, un grupo de artistas e intelectuales franceses y extranjeros encabezados por la directora de teatro Ariane Mnouchkine crearon AIDA (Association internationale de défense des artistes victimes de la répression dans le monde), con el objetivo de denunciar la censura y las violaciones de Derechos Humanos de artistas en distintos países. La asociación proponía acciones creativas, de manera de ejercer presión internacional sobre los regímenes victimarios. Fundada en París, AIDA se desplegó por varias ciudades francesas, por otros países europeos y en Estados Unidos, empleando las redes de contactos de los miembros para articular acciones. El caso de la represión de la dictadura argentina mereció una importante campaña de repudio, potenciada por la presencia de algunos exiliados argentinos en el comité ejecutivo de la asociación. Bajo el título “Cien artistas argentinos desaparecidos” se coordinaron una serie de manifestaciones de solidaridad en distintas ciudades que incluyeron marchas, elaboración de pinturas y postales, así como de un libro sobre la represión cultural en Argentina publicado en París y, poco después, en Madrid. La mayor manifestación de AIDA de esta campaña, una particular marcha realizada en París el 14 de noviembre de 1981, fue filmada, entre otros, por el cineasta argentino Fernando Solanas, miembro activo de la asociación. La experiencia del exilio, y de la AIDA en particular, aparecen como materia prima de su film de ficción El Exilio de Gardel (1985), así como las imágenes capturadas en aquella jornada son incorporadas a las rodadas para el film. Sustentado en archivos poco explorados (documentos escritos y visuales, correspondencia), prensa y entrevistas, este artículo intentará delinear la acción realizada por AIDA y analizar la manera en la que Fernando Solanas construyó su obra reelaborando la memoria de su experiencia en la asociación. El estudio de esta película permitirá colaborar, a partir de un análisis empírico, a la reflexión y teorización sobre la función de la creación como espacio de resistencia, de acción en la esfera pública transnacional y de memoria de experiencias vitalespersonales y colectivas.; In October 1979, a group of French and foreign artists and intellectuals headed by theater director Ariane Mnouchkine created AIDA (Association Internationale de défense des artistes victimes de la répression dans le monde), with the aim of denouncing censorship and violations of Human Rights of artists in different countries. The Association proposed creative actions, in order to exert international pressure on the victimization regimes. Founded in Paris, AIDA was deployed in several french cities, in other european countries and in the United States, using member networks to articulate actions. The case of the repression of the Argentine dictatorship deserved an important campaign of repudiation, boosted by the presence of some argentine exiles in the executive committee of the association. Under the title One hundred argentine artists who disappeared, a series of demonstrations of solidarity were coordinated in different cities, including marches, paintings and postcards, as well as a book on cultural repression in Argentina published in Paris, and shortly afterwards in Madrid. The biggest manifestation of AIDA of this campaign, a particular march in Paris on November 14, 1981, was filmed, among others, by argentine filmmaker Fernando Solanas, an active member of the Association. The experience of exile, and of AIDA in particular, appear as raw material of his fiction film The Exile of Gardel (El Exilio de Gardel, 1985), as well as the images captured on that day are incorporated into the film. Based on little explored archives (written and visual documents, correspondence), press and interviews, this article will try to outline the action taken by AIDA and analyze the way in which Fernando Solanas built his work reelaborating the memory of his experience in the Association. The study of this film will allow to collaborate, from an empirical analysis, to the reflection and theorization on the function of creation as a space of resistance, of action in the transnational public sphere and of memory of personal and collective life experiences.; Em outubro de 1979, um grupo de artistas e intelectuais franceses e estrangeiros encabeçados pela diretora de teatro Ariane Mnouchkine criaram AIDA (Association internationale de défense des artistes victimes de la répression dans le monde), com o objetivo de denunciar a censura e as violações aos Direitos Humanos de artistas em diferentes países. A associação proponha ações criativas, de modo de exercer pressão internacional sobre os regímenes homicidas. Fundada em Paris, AIDA se expandiu a outras cidades francesas, a outros países europeus e aos Estados Unidos, usando as redes de contatos dos membros para articular ações. O caso da repressão da ditadura argentina mereceu uma importante campanha de repudio, potenciada pela presencia de alguns exiliados argentinos no comité executivo da associação.

Do cuidado com o outro á mudança educativa: uma larva? Uma borboleta? Ambas? Ou nenhuma dessas? (Sobre a borboleta); El cuidado del otro al cambio educativo: ¿una oruga? ¿una mariposa? ¿ambas? ¿o ninguna? (A propósito de la mariposa ) Skliar, Carlos Bernardo Carlos Skliar nos invita al en con el otro, acontecimiento que nos atraviesa, nos arrebata y nos destituye de cualqueier certeza que pueda sostenernos. El desdoblamiento de la palabra no fue un simple juego de lenguage, sino la posibilidad de una tartamudez que destruye los mecanismos que sostienen las convenciones lógicas de la lengua, generando intensidades, efectos, disyunciones... incomodando la calma del pensamiento común y tranquilizador. Lanzándonos en la aventura de pensar que el otro es aquél que se afirma por su diferencia, resquebrajando nuestras convicciones. Con estos escritos, Skliar nos co mueve para una conversación en la cual el testigo del proceso de transformación de una larva en mariposa puede llevar en si la potencia de algo no-decible, pero que produce, aunque por contornos imprecisos, la posibilidad de una nueva ética, una ética del “cuidado con el otro para promover un cambio educativo”, incitándonos a pensar “una parte crucial del problema educativo”…; Carlos Skliar nos convida ao em com o outro, acontecimento que nos atravessa, nos arrebata e nos destitui de qualquer certeza que possa nos assegurar. O desdobramento da palavra não foi um simples jogo de linguagem, mas possibilidade de uma gagueira que destrói os mecanismos que sustentam as convenções lógicas da língua, gerando intensidades, efeitos, disjunções... colocando em desconforto a calmaria do pensamento comum e tranquilizador. Lançando-nos na aventura de pensar que o outro é aquele que se afirma por sua diferença, rachando nossas convicções. Com esses escritos, Skliar nos co move para uma conversação em que o testemunho do processo de transformação de uma larva em borboleta pode carregar em si a potência de algo não-dizível, mas que produz, mesmo que por contornos imprecisos, a possibilidade de uma nova ética, uma ética do “cuidado com o outro à mudança educativa”, incitando-nos a pensar “uma parte crucial do problema educativo”...; Carlos Skliar invites us to the other, an event that crosses us, snatches us and remove us of any certainty that can assure us. The unfolding of the words was not a mere play of language, but a possibility of a stuttering that destroys the mechanisms that support the logical conventions of the language, generating intensities, effects, disjunctions ... putting in discomfort the calm and reassuring of common thinking. Taking us on the adventure of thinking that the other is the one who affirms himself by his difference, cracking our convictions. With these writings Skliar moves us to a conversation which witness the process of transformation from a caterpillar into a butterfly can carry within itself the power of something no speakable but which produces, even if by imprecise contours, the possibility of a new ethics, an ethic of "caring for the other to promote an educational change," prompting us to think "a crucial part of the educational problem" ...

Arte rupestre en el Altiplano de Lípez (Potosí, Bolivia); Rock art in the highlands of Lípez (Potosí, Bolivia) Nielsen, Axel Emil Contamos con escasa información sobre el arte rupestre del Altiplano de Lípez. En los años 1980-2000 solo se publicaron referencias a dos sitios. En el presente breve informe, el autor da a conocer otros ocho sitios con arte rupestre que fueron localizados en el curso de prospecciones realizadas en distintos sectores de Lípez.; Information about rock art in the highlands of Lípez is scarce.

Nuevos paisajes urbanos en la frontera: las “paseras” paraguayas entre Posadas (Argentina) y Encarnación (Paraguay) y el plan de obras de Yacyretá (2009-2010); New urban landscapes at the border: the paseras between Posadas (Argentina) and Encarnación (Paraguay) and Yacyretá work plan (2009-2010) Linares, María Dolores El objetivo del presente artículo es describir los cambios en el espacio urbano fronterizo de Posadas (Argentina)-Encarnación (Paraguay), como consecuencias de la ejecución de las obras del Plan de Terminación Yacyretá (etapa final de la Represa Hidroeléctrica Binacional Yacyretá) en los últimos diez años y analizar su impacto en la práctica fronteriza de “comercio hormiga” llevado a cabo por las mujeres paraguayas “paseras”. Para ello se utilizaron entrevistas multisituadas al actor transfronterizo “pasera” entre los años 2009 y 2010, las cuales se procesaron mediante la técnica de “relatos de vida comparados”. También se empleó documentación inédita de la Empresa Binacional Yacyretá como fuentes secundarias; The objective of the present article is to describe the changes in the urban landscape at the border area of Posadas (Argentine)-Encarnación (Paraguay) in the last ten years: the Plan de Terminación Yacyretá (final stage of the Represa Hidroeléctrica Binacional Yacyretá) and analyze its impact on the cross-border dynamics of informal trade by the Paraguayan women called “paseras”. We made multi-situated interviews to the trans-frontier actor called “pasera” between the years 2009 and 2010, which were processed by “compared life-stories” tecniques and we used unpublished documents of the Empresa Binacional Yacyretá as secondary sources.

El Mercosur y sus crisis: análisis de interpretaciones sobre el fracaso de la Integración regional sudamericana; Mercosur and its crisis: explanations for the failure/ success of South American regional integration efforts Botto, Mercedes Isabel El Mercosur atraviesa hoy su crisis más grave. Todos los gobiernos, sin excepción, se han pronunciado sobre la necesidad de desandar los compromisos previos, convirtiendo a la unión aduanera en una mera zona de libre comercio. Esta no es su primera crisis ni tampoco predice el fin del bloque; sin embargo nos lleva a preguntar sobre el porqué de este derrotero zigzagueante que contribuye a la perdida de legitimidad y credibilidad entre las elites políticas y la opinión pública, en general. Para la mayoría de los estudiosos de las ciencias políticas y/o de la economía internacional, la explicación de este fracaso se encuentra en la ausencia de voluntad política y de complementariedad estructural entre los países miembros. La idea que buscamos demostrar en estas páginas es que si bien estas explicaciones son válidas y hasta complementarias, son insuficientes. En este sentido, sostenemos, la necesidad de superar las teorías que se apoyan en factores de índole endógenos para incluir factores exógenos que como la dependencia externa, la incertidumbre financiera y las estrategias cambiantes de las grandes corporaciones transnacionales ejercen un peso determinante sobre las fluctuaciones que caracterizan los intentos de integración latinoamericanos.; Mercosur today traverses its most severe crisis. All Governments, without exception, have spoken about the need to retrace the previous commitments, turning the customs union into a mere free trade area. This is not the first crisis and it does not predict the end of the block. However, leads us to ask about the why of this zigzagging course that contributes to the loss of legitimacy and credibility among political elites and public opinion in general. For the majority of scholars of political science and/or the international economy, the explanation for this failure lies in the absence of political will and structural complementarity between Member countries. The idea that we seek to demonstrate in these pages is that these explanations are valid and even complementary, they are insufficient In this regard, we hold, the need to overcome the theories which rely on endogenous factors to include exogenous factors such as the external dependency, financial uncertainty and changing strategies of transnational corporations exert a decisive weight fluctuations that characterize American integration efforts.
