Viviendas bioclimaticas en Tapalque: sistema de climatización por muros acumuladores de calor (mac): resultados preliminares Discoli, Carlos Alberto; Viegas, Graciela Melisa; San Juan, Gustavo Alberto Se presenta el desarrollo de sistemas de climatización para invierno conformados por muros acumuladores de calor (MAC) y el análisis comparado de diferentes tecnologías. Los sistemas se diseñaron para climatizar prototipos de viviendas bioclimáticas emplazados en Tapalqué, provincia de Buenos Aires (36° 21´ Lat. Sur, 60° 61´ Long. Oeste). Están incluidos en la fachada norte del prototipo y conformados por una masa de acumulación compuesta por piezas apilables industrializadas construidas con dos tecnologías de hormigón, macizas y mixtas que incorporan vainas de PVC llenas con agua tratada. Están cubiertas con una vidriera de simple vidrio con protección nocturna. Se presentan los diseños tecnológicos, las etapas de industrialización, fabricación y montaje. Se realizaron simulaciones de los sistemas incorporados a la vivienda y mediciones en laboratorio. Las simulaciones registraron una mayor performance en locales con muros acumuladores mixtos. Las mediciones en banco de ensayo corroboraron una diferencia de 2°C en las temperaturas registradas en el interior de los locales.

Insulin modifies aging-related inhibition of 1-stearoyl, 2-achidonoylglycerol phosphorylation in rat synaptic terminals Zulian, Sandra Edith; Ilincheta, Monica Graciela; Giusto, Norma Maria The purpose of the present study was to analyze diacylglycerol kinase (DAGK) activity in synaptic terminals from cerebral cortex (CC) and hippocampus (Hp) from adult (3-4 month-old) and aged (26-28 month-old) rats. The effect of insulin through DAGK activity on synaptosomes from adult and aged rats was also analyzed under conditions favoring saturated or unsaturated phosphatidic acid (PA) formation, using exogenous di-palmitoil glycerol (DPG) or 1-stearoyl-2-arachidonoylglycerol (SAG) as substrates. Results showed that the enzymatic activity preferentially uses 1-stearoyl-2-arachidonoylglycerol (SAG) as substrate, thus indicating the presence of -type DAGK. A significant decrease in DAGK activity transforming SAG into PA was also observed in both tissues from aged rats. Western Blot detection of DAGK showed that enzyme content undergoes no changes with aging. [3H]inositol incorporation into phosphoinosites was also analyzed to evaluate the role of DAGK in their synthesis. Data obtained from 3H-inositol incorporation into phosphoinositides revealed that in synaptosomes from aged rats phosphatidylinositol (PI) synthesis is lower than in adult animals. Interestingly, in the presence of SAG, PI synthesis was restored to adult values. DAGK activity over SAG was more highly stimulated by insulin in CC and Hp synaptosomes of aged rats with respect to adult rats. On the other hand, insulin exerted a stimulatory effect on PI and phosphatidylinositol 4 phosphate (PI(4)P) synthesis in synaptosomal CC from aged rats. Taken together, our findings indicate that in aged rats insulin triggers a stimulatory mechanism that reverts the diminished synaptosomal ability to synthesize arachidonoyl phosphatidic acid (20:4 PA). The recovery of this PA species indicates that insulin positively regulates phosphoinositide synthesis.

A data-driven, two-temperature solar model with Alfven waves van der Holst, B.; Manchester IV, W. B.; Frazin, R. A.; Vasquez, Alberto Marcos; Tóth, G.; Gombosi, T. I. We have developed a new three-dimensional magnetohydrodynamic (MHD) solar wind model coupled to the Space Weather Modeling Framework (SWMF), that solves for the different electron and proton temperatures. The collisions between the electrons and protons are taken into account as well as the anisotropic thermal heat conduction of the electrons. The solar wind is assumed to be accelerated by the Alfv en waves. In this paper, we do not consider the heating of closed magnetic loops and helmet streamers, but do address the heating of the protons by the Kolmogorov dissipation of the Alfv n waves in open field line regions. The inner boundary conditions for this solar wind model are obtained from observations and an empirical model. The Wang-Sheeley-Arge model is used to determine the Alfv n wave energy density at the inner boundary. The electron density and temperature at the inner boundary are obtained from the differential emission measure tomography applied to the extreme ultraviolet images of the STEREO A and B spacecraft. This new solar wind model is validated for solar minimum Carrington rotation 2077 (November 20 through December 17, 2008). Due to the very low activity during this rotation, this time period is suitable for comparing the simulated Corotating Interaction Regions (CIRs) with in-situ ACE/WIND data. Although we do not capture all magnetohydrodynamic variables perfectly, we do find that the time of occurance and the density of CIRs are better predicted than by our previous semi-empirical wind model in the SWMF that was based on a spatially reduced adiabatic index to account for the plasma heating.

La reforma del Estado en la provincia de Córdoba en el tiempo inmediatamente posterior a la crisis del 2001: ¿Qué hay de nuevo? Manzo, Alejandro Gabriel El presente trabajo pretende reflexionar en torno al destino del “neoliberalismo” luego de la crisis del 2001. A tal fin realiza un análisis comparativo entre dos procesos de reformas estatales en la provincia de Córdoba: uno primero, activado en 1999 bajo los auspicios del Banco Mundial y del Banco Interamericano de Desarrollo y, otro segundo, puesto en marcha en el 2004 por el nuevo equipo del gobernador De La Sota. Se cierra el artículo con una mirada crítica sobre este último proceso.; This article pretends to analyze the destiny of “neoliberalism” after the crisis of 2001. To such purpose it realizes a comparative analysis between two State Reforms policies in the province of Córdoba: the first one, activated in 1999 under the patronages of the World Bank and the Inter-American Development Bank and, the second one, constructed in 2004 by the new administration of De La Sota. The article concludes with a critical view of the last mentioned process.

Agents That Learn What Argument to Select In Argumentation-Based Negotiations Monteserin, Ariel José; Amandi, Analia Adriana Argument selection is considered the essence of the strategy in argumentation-based negotiation. An agent, which is arguing during a negotiation, has to decide what arguments are the best to persuade the opponent. In fact, in each negotiation step, the agent must select an argument from a set of candidate arguments by applying some selection criterion. For this task, the agent observes some factors of the negotiation context, for instance trust in the opponent, expected utility, among others. Usually, argument selection mechanisms are defined statically. However, as the negotiation context varies from a negotiation to another, defining a static selection mechanism it is not useful. For this reason, we present in this paper a novel approach to personalize argument selection mechanisms in the context of argumentation-based negotiation. The selection mechanism defines a set of preferences that determine how preferable it is to utter an argument in a given context. Our approach maintains a hierarchy of preferences in order to learn new preferences and update the existing ones as the agent experience increases. We tested this approach in a simulated multiagent system and obtained promising results.

Trypanosoma cruzi I genotypes in different geographical regions and transmission cycles based on a microsatellite motif of the intergenic spacer of spliced-leader genes Cura, Carolina Inés; Mejía Jaramillo, Ana M.; Duffy, Tomás; Burgos, Juan Miguel; Rodriguero, Marcela Silvina; Cardinal, Marta Victoria; Kjos, Sonia; Gurgel Gonçalves, Rodrigo; Blanchet, Denis; De Pablos, Luis M.; Tomasini, Nicolás; Da Silva, Alexandre; Russomando, Graciela Mabel; Cuba Cuba, Cesar A.; Aznar, Christine; Abate, Teresa; Levin, Mariano Jorge; Osuna, Antonio; Gurtler, Ricardo Esteban; Diosque, Patricio; Solari, Aldo; Triana Chávez, Omar; Schijman, Alejandro Gabriel The intergenic region of spliced-leader (SL-IR) genes from 105 Trypanosoma cruzi I (Tc I) infected biological samples, culture isolates and stocks from 11 endemic countries, from Argentina to the USA were characterised, allowing identification of 76 genotypes with 54 polymorphic sites from 123 aligned sequences. On the basis of the microsatellite motif proposed by Herrera et al. (2007) to define four haplotypes in Colombia, we could classify these genotypes into four distinct Tc I SL-IR groups, three corresponding to the former haplotypes Ia (11 genotypes), Ib (11 genotypes) and Id (35 genotypes); and one novel group, Ie (19 genotypes). Genotypes harbouring the Tc Ic motif were not detected in our study. Tc Ia was associated with domestic cycles in southern and northern South America and sylvatic cycles in Central and North America. Tc Ib was found in all transmission cycles from Colombia. Tc Id was identified in all transmission cycles from Argentina and Colombia, including Chagas cardiomyopathy patients, sylvatic Brazilian samples and human cases from French Guiana, Panama and Venezuela. Tc Ie gathered five samples from domestic Triatoma infestans from northern Argentina, nine samples from wild Mepraia spinolai and Mepraia gajardoi and two chagasic patients from Chile and one from a Bolivian patient with chagasic reactivation. Mixed infections by Tc Ia + Tc Id, Tc Ia + Tc Ie and Tc Id + Tc Ie were detected in vector faeces and isolates from human and vector samples. In addition, Tc Ia and Tc Id were identified in different tissues from a heart transplanted Chagas cardiomyopathy patient with reactivation, denoting histotropism. Trypanosoma cruzi I SL-IR genotypes from parasites infecting Triatoma gerstaeckeri and Didelphis virginiana from USA, T. infestans from Paraguay, Rhodnius nasutus and Rhodnius neglectus from Brazil and M. spinolai and M. gajardoi from Chile are to our knowledge described for the first time.

Justicia caballeresca en América Lastra, Silvia Cristina El subconsciente imaginario de los hispano-indianos, sin duda alguna, fue fuertemente configurado por la lectura y la audición de la narrativa caballeresca hispánica de los siglos XVI y XVII. Pero, aún hoy, es materia de conjetura la incidencia paratextual del discurso caballeresco no sólo como estímulo a la emulación de hazañas y vivencias maravillosas –la mirabilia–, sino como configurador y propulsor de un código regenerador-perfectivo en torno de una específica idea de la justicia.; Reading and listening to 16th and 17th century Hispanic chivalric stories undoubtedly configured the imaginary subconscious of HispanicIndians. But even today, we wonder about the paratextual influence of chivalric discourse not only as a factor for the emulation of prowesses and marvellous experiences –mirabilia–, but also as the configuring factor of a perfectiveregenerating code around a specific idea of justice.

Consejeros del príncipe: Intelectuales y populismo en la Argentina de hoy; Counselors to the prince: Intellectuals and populism in today’s Argentina Palermo, Vicente Antonio Este artículo abordará la relación entre intelectuales públicos y política en la Argentina durante las gestiones de Néstor Kirchner y Cristina Fernández de Kirchner tomando en cuenta principalmente a Ernesto Laclau, por una parte, y al grupo de intelectuales Carta Abierta, por otra. Tanto Ernesto Laclau como el núcleo de Carta Abierta mantuvieron intensos vínculos con ambos presidentes así como una vigorosa participación expresada en debates, presencia en los medios y declaraciones. Esta participación, así como los vínculos con los presidentes, que se intensificaron a partir del conflicto entre el gobierno nacional y los sectores agropecuarios en 2008, fueron intensa y directamente políticos, puesto que se proponían incidir en la configuración político cultural argentina y en las decisiones de actores políticos comenzando por los propios presidentes.; In this article we will address the relationship between public intellectuals and Argentinean politics during the mandates of Néstor Kirchner and Cristina Fernández de Kirchner taking mainly into account Ernesto Laclau, on the one hand, and the group of intellectuals Carta Abierta, on the other hand. Both Ernesto Laclau and Carta Abierta group maintained intense links with both presidents as well as a strong participation showed in debates, presence on the media and statements. This participation, as well as links with presidents, that were intensified after the conflict between the national government and the agricultural and livestock sectors in 2008, were intensively and directly political, since they intended to have a bearing on the Argentinean political-cultural composition and on the decisions of political actors, starting by the presidents themselves.

Alcances y limitaciones del derecho a la vivienda: Los asentamientos Rodrigo Bueno y la Aldea Gay y los programas de recuperación de terrenos; The Scope And Limitations Of The Right To Housing: Rodrigo Bueno And Aldea Gay Settlements And Land Recovery Yacovino, María Paula En este artículo, nos preguntaremos acerca de los contenidos y matices que adquiere el derecho a la vivienda en el accionar de algunas agencias estatales de la ciudad de Buenos Aires, en un contexto caracterizado por mecanismos de planificación urbana que provilegian la lógica del urban design por sobre el urban plannig característico de la ciudad moderna (amendola 2000). Para ello, abordaremos los vínculos que ciertas agencias estatales establecen con los pobladores de algunos espacios habitacionales de la pobreza en la ciudad de Buenos Aires, deteniéndonos en el papel del Estado como productor de problemas y clasificaciones sociales. Examinaremos, en particular, la relación entre los "nuevos asentamientos" y las agencias del Estado, a partir del analisis de dos programas estatales que involcuran sendos espacios urbanos en proceso de recualificación: el Programa de Recuperación de Terrenos de la Reserva Ecológica Cosatnera Sur y el Programa de Recuperación de Terrenos del Parque Natural de la Ciudad Universitaria. Veremos cómo el reconocimiento constitucional del derecho a la vivienda es reinterpretado en cada caso de acuerdo a los proyectos urbanos en marcha para las áreas en cuestión y a la capacidad de presión de los sectores involucrados.; In this article, the contents and nuances of the right to housing in the operation of state agencies in the city of Buenos Aires within a context characterized by mechanisms of urban development that prioritize urban design over urban planning of the modern city are discussed. In so doing, the links that certain State agencies establish with the local inhabitants of impoverished housing in Buenos Aires are examined, attending to the role of the State as a producer of social problems and classifications. In particular, the relations between "new settlements" and State agencies are examined by analyzing two State programs regarding urban spaces that are being reclassified: the land recovery programs of the Costanera Sur Ecological Reserve and the Ciudad Universitaria Natural Park. As is seen, the constitutional acknowledgement of the right to housing is reinterpreted in each case, according to the ongoing urban projects in each area and pressure from of the different sectors involved.

O país do futuro, visto da Argentina Palermo, Vicente Antonio Se trata de una discusión a la luz de las trayectorias históricas de ambos países, de aspecto de la cultura política brasileña, y de las percepciones argentinas sobre Brasil, su presente y su futuro.; Como o Brasil é percebido por seu vizinho mais próximo? Que imagens projeta? Qual é a percepção sobre seu futuro? A partir da análise das trajetórias históricas, expressões da cultura política de ambos os países e alguns textos significativos, o artigo identifica traços fundamentais do Brasil – a continuidade do Estado, a persistência da desigualdade, a suposta cordialidade de seu povo – que ajudam a entender a imagem do Brasil que prevalece na Argentina, o que, por sua vez, permite definir melhor a ideia que os próprios argentinos têm de seu país.

Potentiation of omega-3 fatty acid antidepressant-like effects with low non-antidepressant doses of fluoxetine and mirtazapine Laino, Carlos Horacio; Fonseca, Cristina; Sterin, Norma Beatriz; Slobodianik, Nora; Reines, Analia Gabriela Despite the advances in psychopharmacology, the treatment of depressive disorders is still not satisfactory. Side effects and resistance to antidepressant drugs are the greatest complications during treatment. Based on recent evidence, omega-3 fatty acids may influence vulnerability and outcome in depressive disorders. The aim of this study was to further characterize the omega-3 antidepressant-like effect in rats in terms of its behavioral features in the depression model forced swimming test either alone or in combination with antidepressants fluoxetine or mirtazapine. Ultimately, we prompted to determine the lowest dose at which omega-3 fatty acids and antidepressant drugs may still represent a pharmacological advantage when employed in combined treatments. Chronic diet supplementation with omega-3 fatty acids produced concentration-dependent antidepressant-like effects in the forced swimming test displaying a behavioral profile similar to fluoxetine but different from mirtazapine. Fluoxetine or mirtazapine at antidepressant doses (10 and 20 mg/kg/day, respectively) rendered additive effects in combination with omega-3 fatty acid supplementation (720 mg/kg/day). Beneficial effects of combined treatment were also observed at subeffective doses (1 mg/kg/day) of fluoxetine or mirtazapine, since in combination with omega-3 fatty acids (720 mg/kg/day), antidepressants potentiated omega-3 antidepressant-like effects. The antidepressant-like effects occurred in the absence of changes in brain phospholipid classes. The therapeutic approach of combining omega-3 fatty acids with low ineffective doses of antidepressants might represent benefits in the treatment of depression, especially in patients with depression resistant to conventional treatments and even may contribute to patient compliance by decreasing the magnitude of some antidepressant dose-dependent side effects.fluence vulnerability and outcome in depressive disorders.

Picasso alquimista: Una lectura de "Las Meninas"; Alchemist Picasso: a Reading of "Las Meninas" Lucero, Guadalupe Este texto presenta una lectura de la serie Las meninas según Velázquez que Picasso realizó en 1957, articulada en tres momentos: 1) revisión de las interpretaciones clásicas de Las Meninas, que poco después de la aparición de la serie picassiana se reactivan en torno al clásico texto de Michel Foucault que preludia Las palabras y las cosas; 2) presentación de la serie a la luz de una dialéctica de la falsificación y 3) análisis del vínculo forma-contenido a partir de la problematización de la noción misma de "variación", buscando algunas resonancias con la lógica musical de la variación. Consideramos que la radicalidad del ejercicio picassiano se encuentra en el centro de lo que se le reprocha: su potencia falsificante.; The objective of this essay is to reflect on Picasso's Las meninas según Velázquez, painted in 1957. We have chosen three moments to develop our thesis: in the first place, we will develop a critical revisión of the classical lectures on Las Meninas since Foucault published his essay in Les mots et les choses (1966); secondly, and taking as a starting point Rosalind Krauss' essay on Picasso, The Picasso Papers, we will read the series as a dialectic of fake and falsification, and finally we will analyze the relationship between form and content through the problem-posing of musical variation. We would like to point out that what is revolutionary in Picasso's series is indeed their fake power.

Notas acerca de los sentidos del fracaso escolar Lucero, Cristian; Viamonte Leme, Lourdes Notas acerca de los sentidos del fracaso escolar es un ensayo que, como su nombre lo indica, está compuesto por algunas notas en las que se propone revisar de qué manera y desde qué posición teórica e ideológica se ha analizado la situación del fracaso escolar en América Latina.En su desarrollo se reconsideran las bases sobre las cuales se estableció el proyecto educativo de la modernidad y su relación con las distintas culturas y la forma en la que se procesaron dentro de la escuela.Otra de las notas desarrolla una mirada acerca de que manera la igualdad educativa derivó en diversidad y como la concepción, que en la Argentina se tiene este concepto, genera una clausura de las oportunidades de inclusión social.Durante el trabajo se hace expresa referencia a las teorías que miran al fracaso colocando el acento en el sujeto y a aquellas que lo hacen en el proceso socio histórico que genera el fracaso. Finalmente, se ensaya una relación entre los resultados que obtienen los estudiantes en las evaluaciones nacionales (para el caso argentino) e internacionales y el rol de las políticas en la generación del fracaso escolar.

Post- Filosofía y ''psicobiografías'': Rorty, Derrida y la escritura filosófica Acosta, Jazmín Anahí Siguiendo a Derrida, Rorty propone visualizar la práctica filosófica en la “era post-Filosófica” como una praxis escrita (Rorty, 1991). Según la formulación propuesta en “El progreso del pragmatista” (1992), ésta habrá de visualizarse como una forma de la escritura autobiográfica. A la luz del deconstruccionismo derrideano, y asumiendo la defensa rortyana de la “cultura post-Filosófica” como una “cultura literaria”, esta comunicación aborda los intrincados derroteros que, según Geoffrey Bennington (1996) imbrican filosofía, escritura y vida.; Following Derrida‟s steps, Rorty conceptualizes the philosophical practicing in the post-philosophical era as a written praxis (Rorty, 1991). According to Rorty (“The Pragmatist‟s Progress”, 1992), this praxis should be understood as a kind of autobiographical writing. In the light of Derridian deconstruction and assuming the Rortyan defense of a “Post-Philosophical Culture” as a “Literary Culture”, this paper deals with a series of complex issues which, from the point of view of Geoffrey Bennington (1996), link Philosophy, Writing and Life.

Riesgo y Equidad Laplacette, Graciela Ines; Paolino, Melisa Delia; Suárez, Natalia Se presenta una sistematización de la discusión realizada por las integrantes del grupo Equidad y Salud en relación al concepto de equidad y su vinculación con la salud. Se analiza la historia del concepto de riesgo en la epidemiología y su relación con la temática de equidad en salud. Desde una mirada crítica del concepto de riesgo se presentan algunos de sus aspectos históricos, las limitaciones del paradigma de riesgo y la vinculación del concepto de riesgo con las concepciones de salud y equidad.

Humanidad como fin, justificación de principios kantianos de justicia y diferencia deontológica: una teoría kantiana de la acción para los fundamentos del argumento contractualista-constructivista político Marey, Macarena El objetivo de este artículo es exponer un paso argumental para una justificación kantiana de la aplicación jurídico-política del principio de la humanidad que sea plenamente compatible con la tesis de la diferencia deontológica entre ética y derecho. Dicho paso se ubica en el nivel metaético de justificación de los principios de justicia en el marco del contrato originario. Específicamente, mi tesis interpretativa consiste en que este nivel se inicia con una teoría de la acción por la cual la descripción de los rasgos de los agentes o personas que participan de él resulta compatible con el “hecho del pluralismo”.; The aim of this paper is to develop a step within the justificatory argumentation that bases the juridical-political application of the principle of humanity in a way that makes it fully compatible with the thesis of the deontological distinction between ethics and law. This step belongs to the metaethical level that serves to justify Kant’s principles of justice within the original contract. Specifically, my interpretative thesis holds that this level begins with a theory of action by which the description of the agents or persons that participate in the contract is fully compatible with the fact of pluralism.

Las orientaciones de la política exterior del gobierno de Kirchner y sus continuidades y rupturas con el pasado Torres, Miguel Agustín La política exterior del gobierno de Néstor Kirchner debió desarrollarse en un complejo contexto, definido por fuertes condicionamientos. Además de las creencias propias de la dirigencia oficialista, diversos factores internos y externos influyeron sobre la dirección impresa a la inserción externa del período. Este trabajo se propone como objetivo analizar las orientaciones principales de la política exterior de la presidencia Kirchner y señalar sus convergencias y discontinuidades con respecto a algunos lineamientos desarrollados en las relaciones internacionales de Argentina por administraciones precedentes desde el retorno al ciclo democrático en el año 1983.; The foreign policy of the government of Néstor Kirchner had developed in a complex contest, defined by strong constrains. In addition to the beliefs of the ruling party, internal and external factors influenced the address printed on the external insertion of the period. This paper seeks to analyze the main lines of foreign policy of Kirchner presidency and identify their convergences and discontinuities with some guidelines developed in international relations of Argentina by previous administrations since the return to democratic cycle in 1983.

Los límites de la humanidad: El mito de los ch´ullpa en Marcapata (Quispicanchi), Perú; Les limites de l’humanité: Le mythe des ch’ullpa à Marcapata (Quispicanchi), Pérou; The limits of humanity: The myth of the ch’ullpa in Marcapata (Quispicanchi), Peru Sendón, Pablo Federico En este artículo se presenta y discute el mito de los ch’ullpa ¢ seres del tiempo presolar ¢ tal y como es narrado por los miembros del ayllu Collana del distrito de Marcapata (provincia de Quispicanchi, Cusco) en relación con tres tipos de fuentes: a) la información arqueológica relativa a la ubicación geográfica y espacial de los monumentos funerarios que reciben dicho nombre en los Andes Centrales; b) la información etnológica relativa a otras versiones del mismo mito relevadas entre otras poblaciones campesino-indígenas del sur peruano y del altiplano boliviano; c) la información etnohistórica que, al respecto, ha sido recopilada por diversos especialistas. El objetivo principal del balance consiste en sentar las bases de una perspectiva comparativa del mito en cuestión con miras a trascender las especificidades de un estudio de caso concreto.; Cet article présente et discute le mythe des ch’ullpa (entités du temps pré-solaire) raconté par les membres de l’ayllu Collana du district de Marcapata (province de Quispicanchi, Cusco), à partir de trois types de sources: a) les données archéologiques sur la localisation géographique et spatiale des monuments funéraires qui portent ce nom dans les Andes centrales; b) les données ethnologiques d’autres versions du même mythe enregistrées parmi d’autres populations indigènes paysannes du Sud péruvien et de l’altiplano bolivien; c) les données ethnohistoriques compilées à ce sujet par différents spécialistes. L’objectif principal de ce bilan est de poser les bases d’une perspective comparative de ce mythe et d’aller au-delà des caractéristiques d’une étude de cas concret.; This paper presents and discusses the myth of the ch’ullpa – beings of the pre-solar time – such as it is narrated by the members of the ayllu Collana from the district of Marcapata (province of Quispicanchi, Cusco) in relation to three kind of sources: a) the archaeological information about the geographical and spatial localization of the mortuary monuments which received that name in the Central Andes; b) the ethnological information about other versions of the myth registered among other indigenous-peasant populations from Southern Peru and the Bolivian altiplano; c) the ethnohistorical information which, in relation with the myth, has been registered by several scholars. The main objective of the review is to lay the foundations of a comparative perspective of the myth with the aim to transcend the specificities of a case study.

Satisfacción con la vida, bienestar psicológico y bienestar social en estudiantes universitarios de Buenos Aires; Satisfaction with life, psychological and social well being in college students Zubieta, Elena Mercedes; Delfino, Gisela Isabel La salud refiere no sólo al estado completo de bienestar físico y mental sino también social incorporando a la armonía con el medio ambiente como una necesidad crucial del bienestar. Desde una perspectiva psicológica y social, el bienestar no consiste sólo en la ausencia de síntomas o emociones positivas sino también que la persona se valore a sí misma, tenga relaciones positivas con otros y crea que controla su ambiente (Bilbao Ramírez, 2008). Tomando a la satisfacción con la vida, el bienestar psicológico y el bienestar social como indicadores de salud mental (Keyes, 20051), se realizó un estudio empírico con el objetivo de explorar en los niveles de bienestar de estudiantes universitarios de la ciudad de Buenos Aires. Los jóvenes estudiantes de la muestra presentan niveles apropiados de satisfacción vital y bienestar psicológico aunque un cambio se produce en la percepción del bienestar social. Se detecta un importante déficit en la percepción de progreso y cambio social, en la creencia de que la sociedad controla su destino, sabe donde va y traza intencionalmente el horizonte hacia donde quiere llegar en el futuro; en su capacidad para producir bienestar.; Health in not only related to physical and mental status but also social, integrating the harmony with environment as a critical factor in well being. From a psycho-sociological perspective, well being is not only conceived in terms of symptoms absence or lack of positive emotions but also in the extent that individuals value themselves, experience positive relationships with others and feel control of their environment (Bilbao Ramírez, 2008). Taking satisfaction with life and psychological and social well being as mental health indicators (Keyes, 20052) an empirical study was carried out with the objective of exploring well being levels in a convenient sample of college students from Buenos Aires city. Convergent validity between dimensions was also tested. Youth participants show suitable levels in satisfaction with life and psychological well being but and interesting data show up when perceiving social well being. A deficit in social progress and change perception is detected. Participants do not hold hard believes in society controlling its destiny, in knowing where is going and intentionally determined a future where to go together. Society capacity to produce well being is not clearly perceived by participants.

Supersticiosos y marranos: el discurso anti-mágico de Lope de Barrientos a la luz de la "Cuestión Conversa" Cavallero, Constanza Edith Hacia mediados del siglo XV emergen en Castilla, de modo prácticamente simultáneo, los primeros discursos en contra de los "nuevos cristianos" y un género discursivo novedoso: aquel que, forjado en las entrañas de la alta cultura teologal, se orienta a reprobar prácticas y creencias consideradas supersticiosas. Dado que esta concurrencia cronológica no parece aleatoria, se intentará demostrar que ambas formaciones discursivas se hallan estrechamente vinculadas. La genealogía del discurso antisupersticioso en territorio hispano debe ser comprendida, pues, atendiendo a su imbricación con las crecientes tensiones político-sociales respecto de las minorías religiosas y considerando, particularmente, sus intersecciones con aquellos otros discursos, también novedosos, que irrumpen junto con la emergencia de la llamada "cuestión conversa". El presente trabajo analiza, a partir del estudio de la trilogía de escritos anti-mágicos de Lope de Barrientos, en qué medida estos tratados emergen de (e intervienen en) la tumultuosa coyuntura que sucede a la revuelta anticonversa de 1449. Se intentará demostrar, en este sentido, que dicho acontecimiento genera una reconfiguración en las relaciones de poder-saber en territorio castellano, un cambio en los procedimientos de formación de verdad -ligado, sobre todo, a la novedosa necesidad de moldear un "otro-entre-nosotros"- que permitiría explicar las condiciones de emergencia del género reprobador de supersticiones.
