Cosmological horizons, Noether charges and entropy Donnay, Laura; Giribet, Gaston Enrique It has recently been shown that, in the vicinity of their event horizons, black holes exhibit an infinite-dimensional symmetry. This symmetry captures relevant physical information about the black hole, and in particular about its thermodynamics. Here, we show that the same holds in a cosmological setup. More precisely, we show that around the de Sitter cosmological horizon, an infinite set of diffeomorphisms preserving a sensible set of boundary conditions emerges. These boundary conditions are similar to those considered by Price and Thorne in the context of the membrane paradigm, and permit to accommodate interesting gravity solutions. As for other boundary conditions considered previously, they are preserved by an infinite-dimensional asymptotic isometry algebra that includes supertranslations and two copies of the Virasoro algebra. This symmetry has associated a set of Noether charges that turn out to be conserved, finite, and integrable. We derive these charges explicitly using the covariant formalism and analyze their physical meaning by evaluating them to the case of de Sitter space. In this case, the zero-mode of the charge is found to account for the Gibbons-Hawking entropy of the cosmological horizon. We then consider a much more general set of solutions, including asymptotically de-Sitter black holes and asymptotically Taub-NUT-de Sitter black holes.

A history of the homosexual liberation front and left-wing politics in Argentina; Una historia del frente de liberación homosexual y la izquierda en Argentina; Uma história da Frente de Libertação Homossexual e a esquerda na Argentina. Insausti, Santiago Joaquin Emerging during the seventies in Argentina during the political radicalization and inspired by the rise of the New Left, the Homosexual Liberation Front (Spanish acronym FLH) attempted an alliance with a variety of organizations on the left. My research will trace the mutations in the political discourse and strategies shaping the attempts at allying with the left-wing over time, as well as the tensions and contradictions that it created among both the rank and file, within the FLH, and other organizations.; Surgido en la década del setenta en Argentina en un clima de radicalización política y dentro del marco de la nueva izquierda, el “Frente de Liberación Homosexual” apostará a una alianza con las organizaciones de izquierda. La investigación analizará diacrónicamente tanto las mutaciones en los discursos políticos y en las estrategias de lucha que se articularon en el diseño de esta alianza como las tensiones y contradicciones que esta propuesta generó en relación con las bases, al interior de la agrupación, y con el resto de las organizaciones militantes.; Surgindo durante os anos setenta na Argentina em meio à radicalização política e inspirada pelo surgimento da Nova Esquerda, a Frente de Libertação Homossexual (FLH) tentou uma aliança com as organizações de esquerda. Esta pesquisa visa conhecer, diacronicamente, tanto as mutações no discurso político do FLH e suas estratégias de luta que se articularam no projeto dessa aliança, quanto as tensões e contradições surgidas em relação às bases, dentro do próprio FLH, e com as outras organizações ativistas.

Nota a Verg., Aen. 10.800: El escudo como clave de lectura del enfrentamiento desigual entre Eneas y Lauso Sisul, Ana Clara Al oponerse a Eneas en defensa de su padre herido, Lauso ocupa el lugar de un guerrero consagrado siendo, aún, inexperto. La escena evidencia el conocido motivo virgiliano de la batalla desigual, anticipado en la introducción del personaje en el décimo canto de la Eneida (mox illos sua fata mament maiore sub hosteen Verg. Aen. 10.438) y explicitado en las palabras que el protagonista pronuncia, en vano, para disuadirlo de combatir(...maioraque viribus audes en Aen. 10.811). En este breve trabajo destacamos otro modo utilizado por Virgilio para señalar el desequilibrio: la variación léxica en la nomenclatura de los escudos de los personajes. A continuación, explicitaremos cómo funciona esta estrategia.

A high-quality genome of Eragrostis curvula grass provides insights into Poaceae evolution and supports new strategies to enhance forage quality Carballo, José; Santos, B. A. C. M.; Zappacosta, Diego Carlos; Garbus, Ingrid; Selva, Juan Pablo; Gallo, Cristian Andrés; Diaz, Alejandra Raquel; Albertini, Emiliano; Cáccamo, Mario José; Echenique, Carmen Viviana The Poaceae constitute a taxon of fowering plants (grasses) that cover almost all Earth?s inhabitable range and comprises some of the genera most commonly used for human and animal nutrition. Many of these crops have been sequenced, like rice, Brachypodium, maize and, more recently, wheat. Some important members are still considered orphan crops, lacking a sequenced genome, but having important traits that make them attractive for sequencing. Among these traits is apomixis, clonal reproduction by seeds, present in some members of the Poaceae like Eragrostis curvula. A de novo, high-quality genome assembly and annotation for E. curvula have been obtained by sequencing 602Mb of a diploid genotype using a strategy that combined long-read length sequencing with chromosome conformation capture. The scafold N50 for this assembly was 43.41Mb and the annotation yielded 56,469 genes. The availability of this genome assembly has allowed us to identify regions associated with forage quality and to develop strategies to sequence and assemble the complex tetraploid genotypes which harbor the apomixis control region(s). Understanding and subsequently manipulating the genetic drivers underlying apomixis could revolutionize agriculture.

Normalismo y mujeres. Las maestras en el Quién es Quién en La Plata (1972): trayectorias de una élite intelectual y profesional; Normalism and women. Teachers in the Who is Who in La Plata (1972): trajectories of intellectual and professional elite Rodríguez, Laura Graciela En este artículo abordaremos un tema poco tratado aún y es el estudio de un grupo de maestras normalistas pertenecientes a distintas generaciones, que fueron consideradas parte de la élite intelectual y profesional de la ciudad capital de la provincia de Buenos Aires y por esa razón, sus nombres aparecieron en la edición del diccionario biográfico Quién es Quién en La Plata del año 1972. En este trabajo nos proponemos analizar quiénes fueron estas 31 maestras destacadas a partir de un estudio basado en esta fuente, donde relevaremos: en qué institución/es estudiaron y en qué año/s se titularon, cuál era su estatus civil, qué trabajos tuvieron y cuáles fueron sus otras actividades por fuera del ámbito laboral.; In this article we will present the study of a group of normal teachers belonging to different generations, which were considered part of the intellectual and professional elite of the capital city of the province of Buenos Aires and for that reason, their names appeared in the edition of the biographical dictionary, Who's Who in La Plata of the year 1972. In this work we propose to analyze who were these 31 teachers featured from a study based on this source, where we will show: on what institution they studied and what year/s were titled, what was their civil status, jobs had and which they were their other activities.

"Trasvasamiento generacional no es trasvasamiento ideológico". La revista Extra y el conflicto interno en el peronismo (1973-1974); Generational transfer is not ideological transfer: The Extra magazine and the internal conflict in Peronism (1973-1974) Iturralde, Micaela; Borrelli, Marcelo Hernan Este artículo analiza el posicionamiento editorial de la revista Extra dirigida por Bernardo Neustadt frente al conflicto interno en el peronismo desde la asunción de Héctor Cámpora a la presidencia en mayo de 1973 hasta el fallecimiento del entonces presidente Juan Domingo Perón en julio de 1974. El objetivo es analizar discursivamente el tratamiento que dio a estas disputas, a la creciente radicalización política de sus facciones y al proceso de "depuración ideológica" contra su sector revolucionario de izquierda desde fines de 1973. El trabajo concluye que Extra intentó posicionarse como representante del "centro político", destacando el rol de Perón como eje para la "unidad nacional" y criticando a los sectores revolucionarios de la izquierda peronista.; This article analyzes the editorial positioning of the magazine Extra directed by Bernardo Neustadt against the internal conflict in Peronism since the assumption of Héctor Cámpora to the presidency in May 1973 until the death of the then president Juan Domingo Perón in July 1974. The objective is to discursively analyze the treatment that gave rise to these disputes, to the growing political radicalization of their factions and to the process of "ideological depuration" against their leftist revolutionary sector since the end of 1973. The paper concludes that Extra tried to position itself as representative of the "political center", highlighting the role of Perón as the axis for "national unity" and criticizing the revolutionary sectors of the Peronist left.

A High-Density Linkage Map of the Forage Grass Eragrostis curvula and Localization of the Diplospory Locus Zappacosta, Diego Carlos; Gallardo, Jimena Alicia; Carballo, José; Meier, Mauro Sebastián; Rodrigo, Juan Manuel; Gallo, Cristian Andrés; Selva, Juan Pablo; Stein, Juliana; Ortiz, Juan Pablo Amelio; Albertini, Emidio; Echenique, Carmen Viviana Eragrostis curvula (Schrad.) Nees (weeping lovegrass) is an apomictic species native to Southern Africa that is used as forage grass in semiarid regions of Argentina. Apomixis is a mechanism for clonal propagation through seeds that involves the avoidance of meiosis to generate an unreduced embryo sac (apomeiosis), parthenogenesis, and viable endosperm formation in a fertilization-dependent or -independent manner. Here, we constructed the first saturated linkage map of tetraploid E. curvula using both traditional (AFLP and SSR) and high-throughput molecular markers (GBS-SNP) and identified the locus controlling diplospory. We also identified putative regulatory regions affecting the expressivity of this trait and syntenic relationships with genomes of other grass species. We obtained a tetraploid mapping population from a cross between a full sexual genotype (OTA-S) with a facultative apomictic individual of cv. Don Walter. Phenotypic characterization of F1 hybrids by cytoembryological analysis yielded a 1:1 ratio of apomictic vs. sexual plants (34:27, X2 = 0.37), which agrees with the model of inheritance of a single dominant genetic factor. The final number of markers was 1,114 for OTA-S and 2,019 for Don Walter. These markers were distributed into 40 linkage groups per parental genotype, which is consistent with the number of E. curvula chromosomes (containing 2 to 123 markers per linkage group). The total length of the OTA-S map was 1,335 cM, with an average marker density of 1.22 cM per marker. The Don Walter map was 1,976.2 cM, with an average marker density of 0.98 cM/marker. The locus responsible for diplospory was mapped on Don Walter linkage group 3, with other 65 markers. QTL analyses of the expressivity of diplospory in the F1 hybrids revealed the presence of two main QTLs, located 3.27 and 15 cM from the diplospory locus. Both QTLs explained 28.6% of phenotypic variation. Syntenic analysis allowed us to establish the groups of homologs/homeologs for each linkage map. The genetic linkage map reported in this study, the first such map for E. curvula, is the most saturated map for the genus Eragrostis and one of the most saturated maps for a polyploid forage grass species.

Experiencias en el proceso de reaparición de detenidas y detenidos desaparecidos sobrevivientes en la Sub-Zona 51 durante la última dictadura militar (1976-1983) y en el resto de la década del ‘80 (1983-1989) Rama, Cristian Nahuel El presente trabajo intenta exponer algunos avances de mi tesis de doctorado en Historia, la cual busca indagar en las experiencias de un conjunto de detenidas y detenidos desaparecidos sobrevivientes de los espacios de detención clandestina de la Sub-Zona 51 en distintos contextos políticos, durante la última dictadura cívico-militar y en el resto de la década del 80.La relevancia que justifica el estudio de estos actores está en el hecho de que fueron protagonistas de la conflictividad política de los años 60 y 70, siendo por ello de los principales sujetos represaliados. Además, porque al haber sobrevivido a esa experiencia resultaron ser uno de los principales canales para conocer los alcances de la represión clandestina dictatorial. Se presentará en este trabajo la delimitación del objeto de estudio y el problema de investigación, los principales objetivos, la metodología a utilizar, el marco teórico elegido y algunos de los resultados preliminares.; The present work tries to expose some advances of my thesis of doctorate in History that proposes to investigate in the experiences of a set of detainees disappeared survivors of the spaces of clandestine detention centers of the Sub-Zone 51 in different political contexts, during the last military dictatorship and in the rest of the decade of the eighties. The relevance that justifies the study of these actors is the fact that they were protagonists of the political unrest of the sixties and seventies, being for this reason some of the main subjects of repression; and also, because having survived that experience turned out to be one of the main channels for knowing the scope of dictatorial clandestine repression. The delimitation of the object of study and the research problem, the main objectives, the methodology to be used, the theoretical framework chosen and some of the preliminary results will be presented; O presente trabalho tenta expor alguns avanços da minha tese de doutorado em História, que propõe indagar nas experiências de um conjunto de detentas e detentos desaparecidos sobreviventes dos espaços de detenção clandestina da Sub-Zona 51 em diferentes contextos políticos, durante a última ditadura militar e no resto da década do 80. A relevância que justifica o estudo destes atore estáem que foram protagonistas da conflitividade política dos anos 60 e 70, sendo por isso dos principais sujeitos represaliados. Ademais, porque ao ter sobrevivido a essa experiência resultaram ser um dos principais canais para conhecer os alcances da repressão clandestina ditatorial. Apresentar-se-á a delimitação do objeto de estudo e o problema de investigação, os principais objetivos, a metodologia a ser utilizado, o marco teórico eleito e alguns dos resultados preliminares.

Comparison of the optical light curves of hydrogen-rich and hydrogen-poor type II supernovae Pessi, Priscila Jael; Folatelli, Gaston; Anderson, J. P.; Bersten, Melina Cecilia; Burns, C.; Contreras, C.; Davis, S.; Englert Urrutia, Brenda Nahir; Hamuy, M.; Hsiao, Eric; Martinez, Laureano; Morrell, Nidia Irene; Phillips, M. M.; Suntzeff, N.; Stritzinger, M. D. Type II supernovae (SNe II) show strong hydrogen features in their spectra throughout their whole evolution, while type IIb supernovae (SNe IIb) spectra evolve from dominant hydrogen lines at early times to increasingly strong helium features later on. However, it is currently unclear whether the progenitors of these SN types form a continuum in pre-SN hydrogen mass or whether they are physically distinct. SN light-curve morphology directly relates to progenitor and explosion properties such as the amount of hydrogen in the envelope, the pre-SN radius, the explosion energy, and the synthesized mass of radioactive material. In this work, we study the morphology of the optical-wavelength light curves of hydrogen-rich SNe II and hydrogen-poor SNe IIb to test whether an observational continuum exists between the two. Using a sample of 95 SNe (73 SNe II and 22 SNe IIb), we define a range of key observational parameters and present a comparative analysis between both types. We find a lack of events that bridge the observed properties of SNe II and IIb. Light-curve parameters such as rise times and post-maximum decline rates and curvatures clearly separate both SN types and we therefore conclude that there is no continuum, with the two SN types forming two observationally distinct families. In the V band a rise time of 17 d (SNe II lower and SNe IIb higher), and a magnitude difference between 30 and 40 d post-explosion of 0.4 mag (SNe II lower and SNe IIb higher) serve as approximate thresholds to differentiate both types.

Generaciones y configuraciones militantes en un sindicato docente: ATEN, 1997-2007; Generations and militant configurations in a teachers trade union: ATEN, 1997-2007 Aiziczon, Fernando Cristian El siguiente artículo tiene como objetivo indagar los cambios generacionales ocurridos en la militancia del sindicato docente neuquino ATEN (Asociación de Trabajadores de la Educación de Neuquén) en torno a la última gran huelga de 2007, en la que fue asesinado el maestro Carlos Fuentealba. A partir de entonces, se puede delimitar una trayectoria política generacional contemporánea en la militancia gremial de ATEN, tomando como punto de partida previo la primera gran huelga docente ocurrida en 1997. Considerando el impacto retrospectivo que ocasionó la última acción huelguística (2007), y sobre el análisis de entrevistas orales y documentos sindicales, el artículo demarca los períodos históricos en que las nuevas generaciones comprenden la construcción de su identidad y despliegan su militancia al interior del sindicato. Nuestra hipótesis es que el modo traumático en que fue experimentada la última gran huelga arroja luz sobre transformaciones previas que venían operando en la subjetividad de las nuevas generaciones de docentes, las que indican un cuestionamiento a las prácticas que constituyeron la novel tradición de este sindicato.; The following article aims to enquire about the generational changes that occurred in the trade union militancy of teacher’s ATEN (Association of Education Workers of Neuquén) around the last great strike in 2007, where the teacher Carlos Fuentealba was assassinated. Thereafter it can be delimited a contemporary generational political trajectory in ATEN’s unión militancy, taking as a starting point the first great strike that took place in 1997. Considering the retrospective impact caused by the last strike action (2007), and on the analysis of oral interviews and trade union documents, this article demarcates historical periods in which the new generations understand the construction of their identity and deploy their militancy within the union. Our hypotesis is that the traumatic way in which the last strike was experienced, shed light about previous transformations that were operating in the subjetivity of the new generations of teachers, which indicates a question mark on the practices that constituted the novel tradition of this trade union.

Polycerasoidol, a Natural Prenylated Benzopyran with a Dual PPARα/PPARγ Agonist Activity and Anti-inflammatory Effect Bermejo, Almudena; Collado, Aida; Barrachina, Isabel; Marqués, Patrice; El Aouad, Noureddine; Franck, Xavier; Garibotto, Francisco Matías; Dacquet, Catherine; Caignard, Daniel H.; Suvire, Fernando Daniel; Enriz, Ricardo Daniel; Piqueras, Laura; Figadère, Bruno; Sanz, María-Jesús; Cabedo, Nuria; Cortes, Diego Dual peroxisome proliferator-activated receptor-α/γ (PPARα/γ) agonists regulate both lipid and glucose homeostasis under different metabolic conditions and can exert anti-inflammatory activity. We investigated the potential dual PPARα/γ agonism of prenylated benzopyrans polycerasoidol (1) and polycerasoidin (2) and their derivatives for novel drug development. Nine semisynthetic derivatives were prepared from the natural polycerasoidol (1) and polycerasoidin (2), which were evaluated for PPARα, -γ, -δ and retinoid X receptor-α activity in transactivation assays. Polycerasoidol (1) exhibited potent dual PPARα/γ agonism and low cytotoxicity. Structure–activity relationship studies revealed that a free phenol group at C-6 and a carboxylic acid at C-9′ were key features for dual PPARα/γ agonism activity. Molecular modeling indicated the relevance of these groups for optimal ligand binding to the PPARα and PPARγ domains. In addition, polycerasoidol (1) exhibited a potent anti-inflammatory effect by inhibiting mononuclear leukocyte adhesion to the dysfunctional endothelium in a concentration-dependent manner via RXRα/PPARγ interactions. Therefore, polycerasoidol (1) can be considered a hit-to-lead molecule for the further development of novel dual PPARα/γ agonists capable of preventing cardiovascular events associated with metabolic disorders.

Exports, Terms of Trade and Economic Growth: Evidence from Countries with Different Level of Openness Dabús, Carlos Darío; Delbianco, Fernando Andrés This paper explores the effects of the ratio exports/GDP and the terms of trade on growth among countries with different level of development and openness. These effects vary among subgroups of countries with different openness and per development level. Nonetheless, in general the evidence seems to support the hypothesis stated in this research. In less developed or better endowed for export countries one or both of the explanatory variables mentioned above encourage for economic growth. Specifically, in advanced economies only the ratio exports/GDP is growth promoting when these are open, and have high per capita but small global GDP and/or relative advantages to be growth export-led. In turn, exports or and the terms of trade trends to promote growth in lower middle income countries. Unfortunately, the surprising results came from the poorest countries. They do not are benefited from a more favourable foreign environment. On the contrary, exports are not significant while an improvement in the terms of trade diminishes their growth.

Movilización, derechos indígenas y antropología en colaboración Castelnuovo Biraben, Natalia Sabrina; Castilla, Malena; Valverde, Sebastián En el presente artículo, nos proponemos analizar la dinámica de movilización de un colectivo de investigadores, docentes y estudiantes de la Facultad de Filosofía y Letras de la Universidad de Buenos Aires ―y de otros centros y universidades― junto con agrupamientos indígenas, instituciones, diversos poderes y variadas organizaciones de la sociedad civil. El proceso de organización y movilización se originó tanto a partir de la campaña de estigmatización y criminalización de las comunidades indígenas, como en virtud de la prórroga de la Ley N.° 26.160. En el marco de este propósito general, queremos poner de relieve las articulaciones entre diferentes grupos de trabajo con la dirigencia y los agrupamientos indígenas. Consideramos sumamente importante abordar, en el marco de la revista QueHaceres del Departamento de Ciencias Antropológicas, el modo en que los profesionales de la carrera nos involucramos en esta dinámica novedosa y establecimos una relación de colaboración con los pueblos originarios.

PhiA, a peptidoglycan hydrolase inhibitor of brucella involved in the virulence process del Giudice, Mariela Giselda; Romani, Alexis Mariano; Ugalde, Juan Esteban; Czibener, Cecilia The peptidoglycan in Gram-negative bacteria is a dynamic structure in constant remodeling. This dynamism, achieved through synthesis and degradation, is essential because the peptidoglycan is necessary to maintain the structure of the cell but has to have enough plasticity to allow the transport and assembly of macromolecular complexes in the periplasm and outer membrane. In addition, this remodeling has to be coordinated with the division process. Among the multiple mechanisms bacteria have to degrade the peptidoglycan are the lytic transglycosidases, enzymes of the lysozyme family that cleave the glycan chains generating gaps in the mesh structure increasing its permeability. Because these enzymes can act as autolysins, their activity has to be tightly regulated, and one of the mechanisms bacteria have evolved is the synthesis of membrane bound or periplasmic inhibitors. In the present study, we identify a periplasmic lytic transglycosidase inhibitor (PhiA) in Brucella abortus and demonstrate that it inhibits the activity of SagA, a lytic transglycosidase we have previously shown is involved in the assembly of the type IV secretion system. A phiA deletion mutant results in a strain with the incapacity to synthesize a complete lipopolysaccharide but with a higher replication rate than the wild-type parental strain, suggesting a link between peptidoglycan remodeling and speed of multiplication.

Políticas públicas y derechos humanos en Argentina (2003-2015): interpretaciones, controversias y disputas en el Movimiento de derechos humanos; Human rights policies in Argentina (2003-2015): interpretations and controversies in the Human Rights Movement Andriotti Romanin, Enrique Salvador; Tavano, Carolina Sofia El artículo propone analizar el vínculo entre algunas organizaciones de derechos humanos de la Argentina con los gobiernos kirchneristas, observando, por un lado, las políticas públicas reparatorias más destacadas vinculadas al tratamiento del pasado dictatorial (1976-1983), impulsadas desde diferentes agencias estatales en el período 2003-2015; y, por otro lado, la repercusión (o no) que tuvieron esas políticas en las representaciones sobre el gobierno y el Estado construidas al interior de las organizaciones que cooperaron y confrontaron con los gobiernos kirchneristas. El abordaje metodológico es cualitativo, permitiendo el tratamiento de diferentes fuentes: entrevistas, documentos de las organizaciones y manifestaciones en la prensa escrita, consultándose, también, documentos oficiales, leyes y decretos, y manifestaciones de funcionarios para indagar las políticas públicas desplegadas en ese período.; This article proposes to analyze the link between some Human Rights organizations from Argentina and the kirchner governments, observing, on the one hand, the public policies that stood out most, linked to the treatment of the dictatorial past (1976-1983), promoted by different state agencies between 2003-2015, and on the other hand, the repercussions (or not) that those public policies had in the government and State representations built within the organizations, which cooperated and confronted the kirchner governments. The methodological approach is qualitative, allowing the treatment of different sources: interviews, documents from the organizations and their testimonies in the written press, also consulting official documents, laws and decrees, and testimonies of public officials, to study the public policies developed in those years.

La (re)invención del pasado como gesto de (des)composición de la Pedagogía; (Re)invention of the past as a gesture to (de)compose Pedagogy Ramallo, Francisco El registro del pasado en la educación suele olvidar su potencia pedagógica, construyendo paradójicamente relatos fosilizados y nostálgicos. Sin embargo el cruce matricial de la investigación narrativa y la pedagogía crítica convoca a componer historias que vigorizan y habitan un pasado más sensible y amable con la vida. En este texto se propone perturbar las perspectivas clásicas de la Historia de la Educación con la intención —siempre parcial, fluida, y provisoria— de intervenir en la colonialidad y la normalización de la legitimidad de ‘el’ relato educativo. Particularmente el objetivo aquí es (re)inventar un pasado —el del bachillerato argentino—, a partir de una metodología de investigación narrativa —que pondera tanto los datos del campo como las reflexiones sobre qué se realiza con ellos—; trasgrediendo sus formas e invirtiendo su enunciación como un modo de propiciar gestos que se encaminen a lo que aquí se denomina (des)composición de la pedagogía. Preocupación que deviene en primordial para dejar de interpretarla apenas como ciencia social que estudia la educación, pues de ese modo suele quedar relegada a su uso sistémico, técnico y disciplinar. Las historias recogidas del bachillerato argentino, además, la dislocan de su noción clásica para intentar comprenderla como una narrativa en la que se verbalizan relaciones humanas de educación en un sentido extendido y vital. En síntesis activan un poder discursivo como condición para restaurar otros modos de conocer, ser y saber.; The processes of recording the past in education commonly forget their pedagogic power, thus paradoxically contributing to nostalgic, fossilized accounts. However, the matrix junction of narrative research and critical pedagogies fosters the composition of stories that invigorate and inhabit a more sensitive past —one which is more polite towards life. We hereby aim at disturbing the classical perspectives of History of Education with the partial, fluent and provisional intention of intervening in coloniality and the normalization of the legitimacy of “the” educational narrative. Specifically the objective is a (re) of a past —the past of Argentinian high schools— from a methodology of narrative research —which weighs both the data of the field and the reflections on what is done with them—; by the abolishment of its forms and the inversion of its enunciation as a means to fostering gestures leading to what we call a (de) composition of pedagogy. Preoccupation that becomes paramount to stop interpreting it as a social science that studies education, because in this way it is usually relegated to its systemic, technical and disciplinary use. The stories collected from the Argentinian high schools, dislocate it from its classical notion to try to understand it as a narrative in which human relations of education are verbalized in an extended and vital sense. In short, they activate a discursive power as a condition to restore other ways of knowing, being and knowing.

La Shoá como posmemoria y religión civil: un ejemplo en la literatura argentina contemporánea; Shoah as postmemory and civil religion: an example in contemporary Argentine literature Niemetz, Diego A partir de su especificidad, la Shoá se ha convertido tanto en un objeto de las representaciones como en un objeto de análisis, cuyo estudio excede el campo historiográfico. El concepto de posmemoria (surgido en la década de 1990 para dar cuenta de los relatos que los hijos o nietos de los sobrevivientes del genocidio heredaban de sus mayores) es un ejemplo sobre cómo la trascendencia de la Shoá como experiencia problemáticamente transmisible, obliga a extender las fronteras de la comprensión y, por lo tanto, a desarrollar herramientas y estrategias más eficaces. En este trabajo se analiza "Camino a Auschwitz" una novela gráfica de la literatura argentina contemporánea, que puede leerse como un ejemplo de la posmemoria y que permite, por lo tanto, considerar la pertinencia en la actualidad del concepto. Nuestra hipótesis es que la posmemoria en el arte es la manifestación de la relación que los descendientes entablan con las historias heredadas y que, al mismo tiempo, reflejan la pervivencia, en las vidas de los descendientes, del trauma masivo ocasionado por la maquinaria nazi.; From its specificity, the Shoah has become both an object of representations and an object of analysis, whose study exceeds the historiographical field. The concept of postmemory (emerged in the 1990s to name the stories that the children or grandchildren of genocide survivors inherited from their elders) is an example on how the Shoah, as a problematically transmissible experience, forces to extend the frontiers of understanding and, therefore, to develop more effective tools and strategies. In this paper we analyze "Camino a Auschwitz", a graphic novel of contemporary Argentine literature, which can be read as an example of postmemory and which allows, therefore, to consider the relevance of the concept at the present time. Our hypothesis is that postmemory in art is the manifestation of the relationship between the descendants and the inherited stories. At the same time, these stories, reflect the persistence, in the lives of the descendants, of the massive trauma caused by the Nazi machinery.

La violencia en la institución familiar: estilos de crianza, disciplina y maltrato infantil; Violence in the family institution: parenting styles, discipline and child abuse Matrángolo, Gisela Maricel Las conductas de maltrato infantil suelen ocurrir en el marco de las prácticas de crianza, especialmente en la implementación de pautas disciplinares. En la mayoría de los casos la reprimenda basada en castigos físicos se encuentra naturalizada. En este sentido, distintos estudios indican que frecuentemente, aquellos adultos que han sufrido distintas formas de maltrato en su infancia tienden a reproducirlas sobre sus hijos, de modo que se refuerza la idea de que las pautas de crianza son, en gran medida, aprendidas a partir de la propia experiencia del cuidador. En el caso del maltrato infantil, distintos estudios indican que este tipo de sucesos, altamente estresantes, en muchos casos se configura como traumático, estableciéndose en gran medida como precursores en el desarrollo de distintos trastornos psiquiátricos en la adultez. El presente trabajo tiene como objetivo realizar una revisión del estado del arte de la problemática del maltrato infantil y el desarrollo de trastornos psiquiátricos en la adultez, para este fin se analizaron materiales de distintas bases de datos como Scielo, PsycINFO, Redalyc, Scopus, EBSCO.; Child abuse behaviors usually occur within the framework of parenting practices, especially in the implementation of disciplinary guidelines. In most cases the reprimand based on physical punishment is naturalized.In this sense, different stu dies indicate that frequently, those adults who have suffered different forms of abuse in their childhood tend to reproduce them on their children,so that the idea that parenting patterns are, to a large extent, learned by from the caregiver's own experience.In the case of child abuse, different studies indicate that this type of events, highly stressful,in many cases is configured as traum atic, establishing itself largely as precursors in the development of different psychiatric disorders in adulthood. The present work has as objective to make a review of the state of the art of the problem of child abuse and the development of psychiatric disorders in adulthood, for this purpose we analyze materials from different databases such as Scielo, PsycINFO, Redalyc, Scopus, EBSCO.

Los archivos norteamericanos como recursos para la investigación de la historia argentina del siglo XX; Os arquivos norte-americanos como recursos para a investigação da história argentina do século xx Lvovich, Abraham Daniel En este artículo nos proponemos presentar lo que entendemos son los principales usos potenciales de los archivos públicos de los Estados Unidos como recursos para la investigación histórica sobre la Argentina.

Juventud y Estado en Argentina: analizando la relación entre la educación y la problemática de la seguridad en los márgenes de la ciudad de Rosario; Youth and State in Argentina: analyzing the relationship between education and the problem of security in the margins of the city of Rosario Alucin, Silvia Vanesa En el presente trabajo nos proponemos analizar las formas en que el problema de la seguridad atraviesa a la institución escolar, haciendo foco en su capacidad de construir subjetividades a través de la coordinación y tensión de distintas formas de interpelación, que asociamos a una política de la compasión, una política de la represión y una política del derecho. Partimos teórica y metodológicamente de una perspectiva antropológica, que nos permite explorar la cotidianidad escolar de dos escuelas periféricas de la ciudad de Rosario, provincia de Santa Fe, Argentina. A partir de estas experiencias concretas de instituciones y agentes estatales, llevamos el análisis de las causas de la inseguridad más allá de las condiciones materiales, para reflexionar sobre tres problemáticas que atraviesan a la escuela: el desdibujamiento entre lo legal y lo ilegal, la estigmatización –tanto de lugares como de personas–y la erosión de los imaginarios de futuro.; In the present work we propose to analyze the ways in which the security problem crosses the school institution, focusing on its capacity to construct subjectivities through the coordination and tension of different forms of interpellation, which we associate with a politics of compassion, a policy of repression and a policy of right. We start theoretical and methodological from an anthropological perspective, which allows us to explore the school everyday of two peripheral schools in the city of Rosario, province of Santa Fe, Argentina. Based on these concrete experiences of state institutions and agents, we take the analysis of the causes of insecurity beyond material conditions to reflect on three problems that cross the school: the blurring between legal and illegal, stigmatization –of places and people– and erosion of the imaginary of the future.
