Núñez Demarco, Pablo Andrés Se describe en este trabajo una nueva unidad compuesta por cuarcitas, metaconglomerados, esquistos calcáreos, filitas y mármoles, afectadas por metamorfismo medio por deformación dúctil. Litotipo y área tipo de esta unidad se localiza al margen del camino vecinal que unía la Estancia Vidal con el poblado de Polanco, en el paso de la Cañada del Bañado Grande (33°52’23.57” S 54°59’11.18” O), entre la cañada Tarumán y la cañada de los Talas, en la Estancia Tarumán. Esta unidad se encuentra suprayaciendo al basamento cristalino (gnéisico milonítico) en el departamento de Lavalleja y subyace a los Mármoles de Polanco, a las cuarcitas de Cerro de los Bueyes y a la Formación Barriga Negra.

Fostering urban transformations in Latin America: Lessons around the ecological management of an urban stream in coproduction with a social movement (Buenos Aires, Argentina) Graziano, Martín; de Groot, Grecia Stefanía; Pilato, Laura Daniela; Sánchez, María Laura; Izaguirre, Irina; Pizarro, Haydee Norma Collaborative community-based approaches are proposed as a way to overcome the difficulties exerted by a broad range of social-ecological traps that emerge at the reconfiguration of social-ecological systems onto sustainable paths. Despite this, a deep examination of the social-ecological processes and interactions that constrain these approaches in different urban contexts is still necessary to improve their success. Latin American countries have institutional, political, and social characteristics that could constrain the pathways to sustainability in different ways from countries of the Global North, particularly in their metropolitan areas. Here, we present an experience (2015–2018) held in cooperation with workers of a social cooperative framed in an urban social movement from Argentina, related to the ecological rehabilitation of a highly degraded urban stream through the management of the riparian vegetation and the reintroduction of native macrophytes. The methodology involved a codesign approach based on a set of participatory action-research tools, together with resilience system analysis through causal loop diagrams, and three different interventions of a 200-m reach at the upstream area of the San Francisco stream (Buenos Aires, Argentina). The participatory diagnostic showed a strong negative effect of the current management guidelines on the riparian and aquatic vegetation, reflecting a positive feedback loop that reinforces this negative state, and revealed a hierarchical governance regime associated with the management of the watershed. Furthermore, it detected a strong motivation of local workers to generate transformative actions in terms of the sanitary and social-ecological improvements of the local habitat. The management actions showed a relatively high short-term survival of the macrophyte transplants (30–60% in a period of 2–4 months), displaying a strong spatial structure of the survival units, and downscaling to about 10% in the long term (6–12 months after interventions). A combination of biophysical and social processes related both to institutional and rigidity traps affected the survival of the transplants, reflecting the inertia of the current management programs to ecological improvements of the stream. In summary, the present work highlights the social-ecological constraints arising from transformative collective actions toward the ecological management of a stream at a highly vulnerable and bureaucratic urban context, with implications for social-ecological urban transformations in Latin America and the design of effective participatory governance actions in alliance with local social movements.

Wheat grains damaged by Fusarium graminearum: alterations in yield, toxicity and protein composition Ortega, Leonel Maximilano; Moure, María Candela; Astoreca, Andrea Luciana; Alberione, Enrique Javier; Alconada Magliano, Teresa Maria The aim of this study was to investigate alterations on wheat grains, in relation to yield and quality parameters, such as infection degree, protein composition and toxicity caused by isolates of Fusarium graminearum with different aggressiveness. The disease degree on wheat samples was evaluated by the parameters like incidence, severity, damaged kernels percentage, yield, deoxynivalenol content and protein constitution, which were analyzed employing accurate quantitative statistics. High and positive correlations among the disease degree parameters were found, as well as negative correlations between them and yield, meanwhile, the total protein content was correlated with yield but was not correlated with the disease degree. The data analysis showed that the effect of the isolate was more significant than the cultivar in the disease degree for almost all the studied variables. The variability in the content of the deoxynivalenol mycotoxin showed a positive tendency in relation to the infection degree. As a novel approach, the aggressiveness of the different isolates ranged from high to low allowing us to evaluate a wide range of the aftereffects of the disease.

Quality of Life and Nutritional Parameters of Celiac Patients in Mar Del Plata, Argentina Motta, Estela Leonor; García, Virginia María; Barragán, Santiago; Belloni, Juan; Chisari, Andrea Nancy Background: Celiac disease (CD) is one of the most common causes of chronic malabsorption. The changes that occur in the diet due to the influence of gluten free diet (GFD) lead to a lower content in the intake of fiber and vitamins. Some authors point out that the higher cost of GF foods, the lower availability of those in social events, the impaired patient’s quality of life, could influence the degree of adherence to the GFD. Our aims were to evaluate the nutritional status, identifying the factors that are associated with adherence to the gluten-free diet (DLG) and the quality of life of a group of CD patients in Mar del Plata. Methods: CD patients were recruited from outpatient of clinic and gastroenterology unit of Oscar Alende Hospital, Mar del Plata and Argentina Celiac Association and had blood drawn for micronutrients concentration. Quality of life was evaluated by SF12 questionnaire, factors and adherence to GFD were determined by factors questionnaire and the Celiac Dietary Adherence Test (CDAT). Results: 47% of the participants had high adherence to GFD. The large supply of gluten-free foods without options during social events was significantly associated with the worst adherence to GFD. The average concentrations of folic acid, magnesium, iron and vitamin B12 were within the normal ranges; however, 6.7, 7.0 and 33.3% of the low adherent group showed low serum concentrations of iron, vitamin B12 and folate, respectively, while 7.7 and 53.8% of the high adherent exhibited low serum concentrations of iron and folate, respectively. Approximately 14.2% had anemia, only 7.1% had iron deficiency anemia. 54% of patients reported eating corn-based foods 3 or more times per week. The general perception of health was low in the age range between 18 and 40 years (34.3 ± 22.0) and the energy and vitality values were low in the same group (37.5 ± 25.2). Conclusions: Evaluation of quality of life and micronutrients indicate the need to support the patients in their treatment and to increase the supply of GF foods and the supplementation with vitamins and micronutrients of the GFD.

Las ruinas de la modernidad (Schlegel, Simmel, Onfray, Ponte y el Che Guevara); The ruins of modernity (Schlegel, Simmel, Onfray, Ponte and el Che Guevara) Iriarte, Luis Ignacio En este trabajo propongo un breve recorrido histórico por el concepto de ruina. En las primeras páginas, describo las relaciones entre el estudio romántico de las ruinas y el diseño de un proyecto de modernidad. Luego de analizar las ideas que aportan Georg Simmel y Michel Onfray, describo las transformaciones que se producen en el concepto en la actualidad. Como hipótesis principal, sostengo que a partir del último tercio del siglo XX las ruinas se convierten en elementos deconstructivos de los discursos de la modernidad. Exploro esta idea a través de los libros de Antonio José Ponte La fiesta vigilada y Cuentos de todas partes del imperio. Finalmente, analizo los usos contemporáneos de un resto en particular: la foto que Alberto Korda le sacó al Che Guevara en 1960, convertida en uno de los íconos centrales de la cultura contemporánea.; In this paper I propose a brief historical analysis of the concept of ruin. In the first pages, I describe the relationships between the romantic study of the ruins and the creation of a modernity project. After analyzing the ideas proposed by Georg Simmel and Michel Onfray, I describe the transformations that occur in the concept of ruin today. As a main hypothesis, I argue that from the last third of the twentieth century the ruins become deconstructive elements of the discourses of modernity. I explore this idea through the books of Antonio José Ponte The guarded party and Tales from all over the empire. Finally, I analyze the contemporary uses of a particular rest: the photo that Alberto Korda took from Che Guevara in 1960, and which became one of the central icons of contemporary culture.

La estructura represiva de la Armada Argentina desde una perspectiva regional: Apuntes y consideraciones sobre la Fuerza de Tareas 6 durante la última dictadura militar en Argentina; The repressive structure of the Argentine Navy from a regional perspective: Notes and considerations on Task Force 6 during the last military dictatorship in Argentina Barragán Sáez, Paula Eva Ivonne; Iturralde, Micaela Durante la última dictadura militar en la Argentina (1976-1983) las tres fuerzas militares desplegaron un vasto entramado represivo a lo largo de todo el territorio. La Armada Argentina (ARA) desarrolló un sistema de once Fuerzas de Tareas (FT) y múltiples sedes clandestinas. El conocimiento disponible ha permitido iluminar su funcionamiento dentro de los límites geográficos de la Ciudad de Buenos Aires y principalmente en torno a los desempeños de la FT N° 3 con sede en la Escuela de Mecánica (ESMA). En este artículo proponemos reconstruir las dinámicas y lógicas represivas a escala subnacional, centrándonos en la actividad represiva de la FT N° 6 en la costa atlántica de la Provincia de Buenos Aires. Buscaremos avanzar en la reconstrucción de instancias de articulación entre las fuerzas militares presentes a nivel regional; indagar y profundizar el conocimiento sobre las formas de gestión de los detenidos- desaparecidos; y problematizar, los modelos explicativos predominantes sobre el fenómeno represivo en su fase concentracionaria. El diseño metodológico propuesto se centra en el abordaje sistemático de fuentes provenientes de los procesos judiciales que persiguen los crímenes cometidos por dicha FT en sus diferentes instancias de instrucción, elevación a juicio oral y sentencias.; During the last military dictatorship in Argentina (1976-1983) the military forces deployed a vast repressive network along the territory. The Argentine Navy (ARA) developed a system of eleven Task Forces (FT) and multiple clandestine headquarters. The available knowledge has allowed to illuminate its operation in the geographical limits of the City of Buenos Aires and mainly the performances of the FT N°3 based in the School of Mechanics (ESMA). In this article we propose to reconstruct the repressive dynamics at the subnational level, focusing on the repressive activity of the FT N° 6 on the Atlantic coast of the Province of Buenos Aires. We will seek to advance in the reconstruction of instances of articulation between the military forces present at the regional level; investigate and deepen knowledge about the management methods of disappear; and to problematize, the predominant explanatory models about the repressive phenomenon. The methodological design focuses on the systematic approach of sources from the judicial processes that prosecute the crimes committed by the FT Nº6 in its different instances of instruction, elevation to oral proceedings and sentences.

El papel del Estado en la definición de la política argentina de hidrocarburos: ¿hacia cuál referencial sectorial?; The role of the State in defining the hydrocarbons policy in Argentina: Toward which sectorial referential? Solanas, Facundo; Martínez, Adriana Verónica El propósito de este trabajo es analizar el papel del Estado en Argentina en las últimas tres décadas, a partir de las políticas de hidrocarburos, en especial las referidas al petróleo, a fin de dar cuenta de sus diversas transformaciones. Si los años noventa se caracterizaron por un abrupto cambio referencial en el papel del Estado y, en particular, en su capacidad pro-ductiva y regulatoria en materia de hidrocarburos, pese a la crisis del paradigma neoliberal a comienzos del nuevo milenio, las políticas energéticas en la materia siguen estrategias sectoriales propias del referencial anterior. A partir del análisis de fuentes documentales y datos cuantitativos, este trabajo propone demostrar de qué forma la política petrolera, pese a la compra por parte del Estado de 51 % de las acciones de Yacimientos Petrolíferos Fiscales (YPF), continúa siendo establecida por el mercado.; The purpose of this paper is to analyze the role of the State in Argentina in the last three decades, based on oil policies, in order to understand its different transformations. The 90s were characterized by an abrupt referential change in the role of the state but especially in the productive and regulatory capacity on hydrocarbons. Despite of the neoliberal paradigm crisis on the beginning of the new millennium, energy policies on hydrocarbons still maintained the previous referential sector strategies. From the analysis of documentary sources and quantitative data, this paper aims to demonstrate how oil policy remains managed by market forces despite the fact that 51% of Yacimientos Petrolíferos Fiscales (ypf ) shares were purchased by the State.

Literatura policial y literatura mundial; Crime fiction and world literature Maltz, Hernán Joel Elaboramos una aproximación entre el género policial y algunos debates recientes en torno a la problemática de la literatura mundial. Luego de mencionar la incorporación de lo global como tema de algunas ficciones, de explicitar el lugar de enunciación del analista y de repasar brevemente los aportes que piensan dicha intersección, planteamos dos abordajes: por un lado, nos apoyamos en los trabajos de Casanova y Moretti para pensar la literatura policial desde una perspectiva global y asimétrica; por otro, a partir de Luhmann, elaboramos otra aproximación teórica desde una perspectiva sistémica.; The article proposes an approach to crime fiction and recent debates around the problem of world literature. After determining the incorporation of the global as a theme in some fictions, evincing the place of enunciation of the analyst, and briefly reviewing the contributions that explore that intersection, two approaches are offered. On the one hand, and following the works by Casanova and Moretti, crime fiction is considered from a global and asymmetric perspective. On the other, and inspired by Luhmann, another theoretical approach is elaborated from a systemic perspective.

Nota sobre las ciencias económicas y el trabajo del economista; Note on the economic sciences and economist's work Crespo, Ricardo Fernando Esta breve nota recoge las ideas acerca de la clasificación de las ciencias económicas de John Stuart Mill, Carl Menger, y John Neville Keynes, las combina con otras ideas de economistas actuales, en orden a proponer la necesidad de considerar una multiplicidad de ciencias económicas trabajando conjuntamente.; This brief note picks up John Stuart Mill, Carl Menger, and Neville Keynes ideas on the classification of economic sciences, and combines them with other ideas of contemporary economists in order to propose the convenience of considering a multiplicity of economic sciences working together.

La familia católica de Comodoro Rivadavia y el peronismo: conflictos antes y después del golpe de Estado de 1955; The Catholic family of Comodoro Rivadavia and Peronism: conflicts before and after 1955 Carrizo, Gabriel Alejandro; Vicente, Mariana Paola Este artículo presenta el análisis de dos preocupaciones que expresaba la Iglesia católica entre finales del primer peronismo y la denominada "Revolución Libertadora": la educación y la familia. Para ello se enfoca la mirada sobre los posicionamientos de distintas organizaciones que conformaban la "familia católica" de la ciudad de Comodoro Rivadavia: la Liga de Madres y la Liga de Padres de Familia, el Partido Demócrata Cristiano, el periódico católico De Pie y la Congregación Salesiana. Se demuestra que los cuestionamientos expresados en el tramo final de la experiencia peronista, mantuvieron vigencia ante las autoridades surgidas del golpe de 1955 y en el caso educativo marcaron el antecedente inmediato al conflicto por la "Laica o Libre".; This article presents the analysis of two concerns that expressed by the Catholic Church between the end of the “first Peronism” and the denominated "Revolución Libertadora": education and family. Thats why, the focus is on the positions of different organizations that made up the "catholic family" of Comodoro Rivadavia: “Liga de Madres” and the “Liga de Padres”, “Partido Demócrata Cristiano", the Catholic newspaper “De Pie” and Salesian Congregation. It shows that the questions expressed in the final section of the Peronist experience remained valid in the face of the authorities that emerged from the 1955 putsch and marked in the educational case the immediate antecedent to the conflict by the "Laic or Free".

Lengua y literatura en tiempos del Ni una menos: Emancipación, feminismos, luchas sociales Carbone, Rocco Este trabajo pretende entramar algunas reflexiones sobre la lengua inclusiva y la literatura argentina (urbana) del siglo XXI. La lengua –“la palabra (la palabra autorizada) todavía es mayoritariamente de los hombres”[1]– y la literatura son instituciones patriarcales, condición que en la Argentina comienza a ponerse en tela de juicio. La hipótesis que me gustaría probar aquí es que la lengua y literatura empezaron a despatriarcalizarse a partir de las conmociones sociales (culturales: en sentido amplio) visibilizadas por un movimiento feminista plural, colectivo de protesta: Ni una menos. Para entramar una reflexión sobre la lengua inclusiva –elemento cultural sobre el cual no hay acuerdo en el universo hispanohablante– y mostrar cómo se expresa un sector de la literatura argentina del siglo XXI (escrita por mujeres), haré pie en tres categorías reflexivas: emancipación, patriarcado y feminismo(s). Luego trataré de entrar en los pliegues de la lengua inclusiva y a manera de conclusión propondremos propondré una cita de una novela de Ana Ojeda (Buenos Aires, 1979), Vikinga Bonsái (2019).

Video etnográfico boliviano de la década del ochenta: (Otra) identidad, historia y territorio; Bolivian ethnographic video of the eighties: (Other) identity, history and territory Aimaretti, Maria Gabriela La problematización de las narrativas de identidad nacional, el "redescubrimiento" del mundo indígena, el territorio y la historia, fueron asuntos que la nueva agenda democrática empujó a tratar a los jóvenes videastas bolivianos. En efecto, la salida de las dictaduras, la organización política creciente de los sectores indígenas, su protagonismo en federaciones y sindicatos, y la autovaloración cultural e ideológica que se manifestaba en prácticas y discursos, fueron factores contextuales que catalizaron el interés de realizadores noveles como Eduardo López Zavala y Néstor Agramont, quienes estaban construyendo un camino propio dentro de la escena audiovisual local articulándose de modo diverso con el campo documental, la investigación histórica y etnográfica, la educación popular y la antropología.Este trabajo aborda una de las tendencias de producción del video boliviano de la década del ochenta, la etnográfica, circunscribiendo su atención a los videos que López Zavala y Agramont concretaron en el marco del Centro de Educación Popular QHANA: Levantémonos todos (1987) -que muestra formas de organización político-comunitarias y, asociado a ello, la defensa de las reservas en recursos naturales de la zona del salar de Uyuni-, y, El camino de las almas (1989) -el cual tematiza el robo y comercialización de tejidos tradicionales. Tras comentar el escenario de inscripción de ambos materiales, y examinar algunas aportaciones conceptuales respecto de las nociones de territorio y paisaje, analizaremos los videos atendiendo a las figuraciones con las cuales se representó la Otredad indígena, el pasado y los conflictos sociales, y la noción de derechos.; The problematization of the narratives of national identity, the “rediscovery” of the indigenous world, the territory and history, were issues that the new democratic agenda pushed to treat the bolivian young filmmakers. Indeed, the outcome of dictatorships, the growing political organization of the indigenous sectors, their prominence in federations and unions, and the cultural and ideological self-valorization manifested in practices and discourses, were contextual factors that catalyzed the interest of new filmmakers as Eduardo López Zavala and Néstor Agramont, who were building their own path within the local audiovisual scene, articulating themselves in a diverse way with the documentary field, historical and ethnographic research, popular education and anthropology. This work focuses on one of the production trends of the Bolivian video of the eighties, the ethnographic, circumscribing its attention in the videos that López Zavala and Agramont materialized within the framework of the QHANA Popular Education Center: Levantémonos todos (1987) – which shows forms of community-political organization and, associated with it, the defense of the reserves in natural resources of the Uyuni salar area –, and, El camino de las almas (1989) – which thematizes the theft and commercialization of traditional abb. After commenting the historical context of both materials; and examine some conceptual contributions about the notions of territory and landscape, we will analyze the videos taking into account the representations with which the other indigenousness was represented, the past and social conflicts, and the notion of rights.

Building decolonizing pedagogies: notes from work praxis in social organizations; La construcción de pedagogías descolonizadoras: notas desde la praxis del trabajo en organizaciones sociales; A construção de pedagogias descolonizadoras: notas desde a práxis do trabalho em organizações sociais Guelman, Anahí; Palumbo, María Mercedes This article is based on the work and reflections expressed in the qualitative research carried out in self-managed cooperative and productive ventures by an Argentinean social organization. A series of provisional notes are presented regarding the characteristics that, based on fieldwork and aligned with previous research, we consider key in conceptualizing decolonizing pedagogies. As posited in this article, thinking about decolonizing pedagogies implies addressing: 1) place of knowledge and “other” epistemic subjects; 2) potential of labor as an educational principle; 3) inserting training into daily life and the community; 4) openness to emotions; and finally, 5) collective framework. The reflections on these five aspects seek to open possibilities of problematizing and discussing pedagogies with the purpose of decentralizing colonial education.; El presente artículo parte de las elaboraciones y reflexiones producidas en el contexto del trabajo de investigación de tipo cualitativo realizado en emprendimientos productivos autogestivos-cooperativos desarrollados por una organización social en la Argentina. Se esbozan una serie de notas provisorias en torno a las características que, partiendo del trabajo de campo realizado y en diálogo con los antecedentes investigativos, nos resultan centrales en la conceptualización de las pedagogías descolonizadoras. Como se propone en el artículo, pensar pedagogías descolonizadoras implica abordar el lugar de los saberes y de los sujetos epistémicos otros, la potencialidad del trabajo como principio formativo, la inserción de la formación en la cotidianeidad y la comunidad, la apertura a lo afectivo y, finalmente, el marco colectivo. Las reflexiones desarrolladas en torno a estos cinco aspectos pretenden contribuir a la apertura de horizontes de problematización y discusión sobre las pedagogías en un gesto de descentramiento de la educación colonial.; O presente artigo baseia-se nas afirmações e reflexões produzidas no contexto do trabalho de pesquisa de tipo qualitativo realizado em empreendimentos produtivos autogestivos-cooperativos desenvolvidos por uma organização social na Argentina. Esboçamos uma série de notas provisórias em torno às características que, a partir do trabalho de campo realizado e em diálogo com os antecedentes de pesquisa, consideramos centrais na conceitualização das pedagogias descolonizadoras. Como proposto no artigo, pensar pedagogias descolonizadoras implica abordar o lugar dos conhecimentos e dos sujeitos epistêmicos outros, a potencialidade do trabalho como princípio formativo, a inserção da formação na cotidianidade e a comunidade, a abertura para o afetivo e, finalmente, o marco coletivo. As reflexões desenvolvidas em torno a estes cinco aspectos visam contribuir para a problematização e discussão sobre as pedagogias, em um gesto de descentramento da educação colonial.

Los de afuera no son de palo: notas reflexivas sobre una investigación de amor en varones gays; The others matter: reflexive notes on a research about love among gay men Marentes, Maximiliano En el presente trabajo propongo un ejercicio de reflexividad metodológica sobre las categorí­as con las que fui comparado en mi investigación sobre amor en varones gais. El objetivo es reconocer que dichas categorí­as no son arbitrarias sino que adquieren un sentido particular en la conformación de parejas, entendidas estas como una red que se ensambla por más de dos personas. Así­, ser comparado con un levante, un tercero en discordia, un terapeuta y un amigo lleva a dinamizar el lugar de investigador, al tiempo que aporta información sobre el amor gay realmente existente.; In this paper I propose an exercise of methodological reflexivity on the categories to which I was compared in my research about love among gay men. e aim is to recognize that those categories are not arbitraries but get particular sense in the conformation of couples. I understood the couples as a network assembled for more than two individuals. So, being compared to a guy trying to date, a third party, a therapist and a friend makes the researcher role more dynamic, at the same time that provides information about really existing gay love.

Narrativas dominantes y violencia epistémica en la historiografía de las danzas argentinas: posibilidades de desobediencia; Dominant Narratives and Epistemic Violence in Argentine Dances Historiography: Possibilities of Disobedience Cadús, María Eugenia El artículo analiza la violencia epistémica en la historiografía de la danza argentina y ofrece un camino hacia la desobediencia epistémica. En tanto la narrativa dominante de la historia de ladanza argentina se centra en la idea de "La Danza (con mayúscula) 'en'Argentina", se asume que esta declaración epistémica implica un punto de vistapolítico, ideológico y estético particular que enfatiza una perspectiva colonialista. En primer lugar analizamos la concepción de "Danza" (con mayúscula) que refiere a la danza escénica como práctica dominante principalmente danza moderna y contemporánea, y ballet en cuanto oculta un posicionamiento eurocéntrico y universalista. Por otra parte, analizamos la preposición "en" que implica una identidad basada en la danza concebida como una importación colonial y evita definir loque Walter Mignolo denomina como locus de enunciación. A través del análisis crítico de esta frase, fundamentado en el examen de textos centrales en la historiografía de las danzas argentinas, el artículo propone un "desenganche epistémico". En segundo término, se exponen ciertas claves para un cambio epistémico decolonial tales como la "lugarización", el cuestionamiento del "presentismo" y la linealidad temporal tendiente a la teleología del modernismo, y la inclusión de Otredades a partir del cuestionamiento de la lógica de archivo dominante por medio del concepto de "repertorio" y de "montaje". El texto aborda los siguientes interrogantes: ¿Cómo se construyen las genealogías en la historia de la danza argentina? ¿Cómo se crea el canon?¿Cuál es la hegemonía en los estudios de danza argentina? ¿Qué archivos son privilegiados? ¿Qué voces y cuerpos son silenciados a través de esta narrativa?¿Cuáles son las claves para una desobediencia epistémica en la historiografía de la danza o las danzas argentinas?.

La huelga de estudiantes en la Escuela Práctica de Agricultura y Ganadería “Las Delicias” (Entre Ríos, 1918); The strike of students in the Practical School of Agriculture and cattle raising “Las Delicias” (Entre Ríos, 1918) Cian, Janet Priscila A inicios del siglo XX en Entre Ríos se impulsó la enseñanza agrotécnica de carácter provincial, aunque también tuvo participación el Ministerio Nacional de Agricultura que organizó una escuela en 1900. En este artículo se reconstruye la situación institucional de la Escuela Práctica “Las Delicias”, que fue marco de la huelga estudiantil ocurrida en 1918, para explicar los motivos de la misma, entre los cuales tuvieron un papel decisivo las dificultades en la organización escolar y la fragilidad de la política de enseñanza agrícola nacional. Esto permite poner en cuestión que dicha huelga haya sido una derivación del descontento estudiantil que estaba desarrollándose en las instituciones educativas universitarias de otras provincias y en los institutos secundarios de la ciudad de Paraná.; At the beginning of the 20th century in Entre Ríos, provincial agrotechnical education was promoted, although the National Ministry of Agriculture, which organized a school in 1900, also participated. In this article, the institutional situation of the Las Delicias Practical School which was the framework of the student strike in 1918, is reconstructed to explain the reasons for it, among which the difficulties in school organization and the fragility of the national agricultural education policy were decisive. This allows to question whether this strike was a derivation of the student discontent that was developing in the university educational institutions of other provinces and secondary schools in the city of Paraná.

Insights from quantitative and mathematical modelling on the proposed WHO 2030 goals for Chagas disease Cohen, Joel E; zu Dohna, Heinrich; Gurtler, Ricardo Esteban Chagas disease (CD) persists as one of the neglected tropical diseases (NTDs) with a particularly large impact in the Americas. The World Health Organization (WHO) recently proposed goals for CD elimination as a public health problem to be reached by 2030 by means of achieving intradomiciliary transmission interruption (IDTI), blood transfusion and transplant transmission interruption, diagnostic and treatment scaling-up and prevention and control of congenital transmission. The NTD Modelling Consortium has developed mathematical models to study Trypanosoma cruzi transmission dynamics and the potential impact of control measures. Modelling insights have shown that IDTI is feasible in areas with sustained vector control programmes and no presence of native triatomine vector populations. However, IDTI in areas with native vectors it is not feasible in a sustainable manner. Combining vector control with trypanocidal treatment can reduce the timeframes necessary to reach operational thresholds for IDTI (<2% seroprevalence in children aged <5 years), but the most informative age groups for serological monitoring are yet to be identified. Measuring progress towards the 2030 goals will require availability of vector surveillance and seroprevalence data at a fine scale, and a more active surveillance system, as well as a better understanding of the risks of vector re-colonization and disease resurgence after vector control cessation. Also, achieving scaling-up in terms of access to treatment to the expected levels (75%) will require a substantial increase in screening asymptomatic populations, which is anticipated to become very costly as CD prevalence decreases. Further modelling work includes refining and extending mathematical models (including transmission dynamics and statistical frameworks) to predict transmission at a sub-national scale, and developing quantitative tools to inform IDTI certification, post-certification and re-certification protocols. Potential perverse incentives associated with operational thresholds are discussed. These modelling insights aim to inform discussions on the goals and treatment guidelines for CD.

Perspectivas darwinistas sobre la mente y la conducta humanas: alcances, limitaciones e implicancias educativas; Darwinian perspectives on the human mind and behavior: scope, limitations and educational implications Gonzalez Galli, Leonardo Martin En este trabajo caracterizo las aproximaciones darwinistas a la conducta y mente humanas, especialmente la psicología evolucionista, y analizo las principales críticas que dichas aproximaciones han recibido. A tal fin recurro a la crítica de Jean Marie Schaeffer a la tesis de la excepcionalidad humana y a la perspectiva semántica de las teorías científicas de Ronald Giere. Concluyo que las principales críticas (reduccionismo, determinismo y sesgo ideológico) no son aplicables a la psicología evolucionista en tanto programa de investigación. Concluyo también que no se puede sostener a priori que el enfoque darwiniano no sea aplicable a la mente y conducta humanas. Finalmente discuto algunas implicancias educativas de estos debates.; In this work I characterize Darwinian approaches to human behavior and mind, especially evolutionary psychology, and analyze the main criticisms that these approaches have received. To this end I resort to Jean Marie Schaeffer’s criticism of the thesis of human exceptionality and the semantic perspective of scientific theories of Ronald Giere. I conclude that the main criticisms (reductionism, determinism and ideological bias) are not applicable to evolutionary psychology as a research program. I also conclude that it cannot be held a priori that the Darwinian approach is not applicable to the human mind and behavior. Finally, I discuss some educational implications of these debates.

Adaptación lingüística, estructura factorial y fiabilidad del Inventario de Perspectiva Temporal de Zimbardo para Buenos Aires; Linguistic adaptation, factorial structure and reliability of Zimbardo Time Perspective Inventory for Buenos Aires Brenlla, María Elena; Zapater, Joaquín; Germano, Guadalupe La perspectiva temporal es un término psicológico que refiere al modo en que las personas ordenan sus experiencias en categorías temporales. Se asocia con la salud mental, las conductas de riesgo y los proyectos a futuro. El Inventario de Perspectiva Temporal de Zimbardo (ZTPI; Zimbardo y Boyd, 1999) es un cuestionario autoadministrable que evalúa la perspectiva temporal. En este artículo se informan los resultados del estudio psicométrico del ZTPI, realizado en Buenos Aires, sobre la base de la adaptación española del inventario. En este sentido, un propósito fundamental fue analizar si la adaptación española del ZTPI es igualmente válida para su uso en Argentina. Para ello, se llevó a cabo una adaptación lingüística del instrumento que redundó en cambios en la redacción y contenido en la presente versión para adecuarlas a las particularidades del habla en Argentina. Con esta versión, se realizó un estudio piloto con una muestra de 323 personas adultas cuyos datos permitieron el análisis básico de sus propiedades psicométricas. Las evidencias de validez interna corroboran la estructura de cinco componentes del estudio original. La fiabilidad de los ítems en cada factor fue satisfactoria (valores α entre .59 y .78). Los resultados de validez externa muestran asociaciones significativas entre pasado negativo y malestar psicológico (r = .43; p < .005), presente fatalista y locus de control (r = .45; p < .005), presente hedonista y autoeficacia generalizada (r = .31; p < .005). Respecto a la variabilidad obtenida en las puntuaciones del ZTPI se sugiere que, en parte, se debe al nivel educativo y, secundariamente, al sexo. Conforme aumenta la edad, el patrón de orientación al presente hedonista decrece. Lo contrario sucede con el predominio de la orientación futura.; Time perspective is a psychological term that refers to the process by which a person sorts out personal experiences into temporal categories. It is associated with mental health, risk behaviors, cognitive and emotional empathy, and future goals. The Zimbardo Time Perspective Inventory (ZTPI) from Zimbardo & Boyd (1999) is a self-administered questionnaire consisting in 56 items with 5 answer options. It examines time perspective in a quantifiable way. The questionnaire was translated and adapted to many languages and cultures, most of which reported satisfactory psychometric evidences. The Spanish version of the ZTPI was first made in Spain by Diaz-Morales (2006). Based on this version, two other Spanish speaking countries, Chile and Mexico, made their own version of the questionnaire. In Argentina, there is a version of the ZTPI valid only for teenagers. In the present work the original ZTPI was translated by 3 experts and a linguistic adaptation was done in order to adequate the items to Argentinean speech. A pilot test using the Diaz-Morales version was carried out. Based on the independent and blinded translations, and on the results of the pilot test, an analysis was made. Many items of the Spanish versions were kept, but 34 of the 56 items were changed so as to be compressible for Argentinians. This work resulted in an Argentinian version of the ZTPI, specially done for that culture. Using this version, a pilot study was done with a sample of 323 adults from Buenos Aires. The analysis shows that the reliability of items was satisfactory (values between a = .59 to a = .78). Internal validity evidences confirm the 5 factors structure shown by the authors. External validity was analyzed showing significant associations among negative past and psychological distress (r = .43; p < .005), present fatalistic and locus of control (r = .45; p < .005) and present hedonistic and Self-efficacy (r = .31; p < .005). To study the error variance due to passing of time, test-retest was carried out, showing high and positive correlations. This means that scores of time perspective show time stability. In conclusion, the results of the psychometric analysis are satisfactory. This indicates that the ZTPI is a reliable and valid instrument that can be used to evaluate time perspective in adults from Buenos Aires. An analysis of the variability of ZTPI punctuations was done. It suggests that they are due to two main reasons: educational level and sex. Regarding educational level, significant variations were shown in four of the five factors. The only factor that showed no difference was the positive past. Considering sex, significative differences were shown in four of the five factors of the test, in which medias were higher in women than in men. No differences were shown in hedonistic present factor. With respect to the age, present hedonistic orientation decrease as age grows. On the other hand, as age grows future orientation grows too. These three variables (educational level, sex and age) explain the variability, but it is a partial significance. This implies that time orientation can be understood as a personality characteristic. Consequently, the different punctuations people get in the ZTPI are due to individual differences. Suggestions are made in order to make a definitive adaptation of the ZTPI for Argentina. The most important are increasing the sample with people from other regions of the country and increase the sample to make test-retest. Finally, future research could be oriented to make a short version of the ZTPI and use the questionnaire for evaluation in clinical samples to understand how time perspective works in psychopathologies and then use time orientation as a valid variable for diagnosis and treatment.

Acerca de la problemática de la reparación de los crímenes de Estado; About the problem of State crimes reparation Schneider, Ludmila Nair La problemática de la reparación de los actos criminales ejercidos por representantes del Estado contra su propia población ha cobrado un impulso sin precedentes tras la Segunda Guerra Mundial. Desde entonces, programas de diverso alcance han configurado intentos por reparar a las víctimas de graves violaciones a los derechos humanos perpetradas durante dictaduras militares o conflictos internos en diversas latitudes. En este paradigma se inscribe esta presentación, cuyo objetivo principal consiste en describir y analizar los lineamientos a partir de los cuales se ha abordado hasta el momento la reparación de los crímenes de Estado. La intención que guía este análisis es identificar sus alcances y limitaciones para construir a partir de una mirada crítica sobre los mismos un marco teórico para la comprensión de la problemática de la reparación. Para ello, se situará la reparación en el marco de la consolidación de la perspectiva de las víctimas, cuyo punto más álgido de desarrollo lo constituye la concepción de reparación integral. Dado que en ese escenario se sitúa la perspectiva de la justicia transicional, que ha hegemonizado los desarrollos relativos al campo de las reparaciones en las últimas décadas, serán analizados sus postulados principales, profundizando en las múltiples tipologías que se han construido desde la justicia transicional para categorizar las medidas tendientes a la reparación. Para finalizar, se presentarán algunas conclusiones preliminares que deberán ser retomadas en futuros trabajos como puntos de partida para la elaboración de un marco conceptual que permita profundizar la comprensión de la reparación.; The problem of repairing criminal acts pursued by representatives of the State against its own population has gained an unprecedented momentum after the Second World War. Since then, programs of varying scope have configured attempts to repair the victims of serious human rights violations perpetrated during military dictatorships or internal conflicts throughout the world. This presentation is part of this paradigm, whose main objective is to describe and analyze the guidelines from which the reparation of State crimes has been addressed up to now. The intention that guides this analysis is to identify its scope and limitations in order to construct, from a critical view of them, a theoretical framework for the understanding of the problem of reparation. Reparation will be placed within the framework of the consolidation of the perspective of the victims, whose highest point of development is the concept of integral reparation. Given that the perspective of transitional justice, which has hegemonized the developments related to the field of reparations in the last decades, is situated in this scenario, its main postulates will be analyzed, deepening in the multiple typologies that have been constructed from transitional justice to categorize the measures tending to repair. To conclude, some preliminary conclusions will be presented that should be taken up in future work as starting points for the elaboration of a conceptual framework that allows deepening the understanding of reparation.
