Laelapid mites (Mesostigmata) ectoparasites of Oligoryzomys (Rodentia: Cricetidae) in north-eastern and central Argentina; Ácaros laelápidos (Mesostigmata) ectoparásitos de Oligoryzomys (Rodentia: Cricetidae) en el noreste y centro de la Argentina Savchenko, Ekaterina; Melis, Mauricio Ezequiel; Lareschi, Marcela Laelapidae mites are distributed throughout the world and include many species that are common parasites of cricetid rodents. Although knowledge of the host associations of laelapids is well recorded for the Oligoryzomys species in Buenos Aires province in Argentina, this information is scarce or null for other regions of the country and for some species of this genus. Here we report new records of laelapid mites associated with Oligoryzomys flavescens, O. fornesi and O. nigripes, obtained during collections carried out for more than a decade in north-eastern and central Argentina, covering a wide geographic range that includes sympatric sites for these rodents. Herein, laelapids associated with these rodents are reported for the first time in the provinces of Chaco and Formosa; and also for the first time records of laelapids in O. fornesi. All three rodent species are associated with the laelapids Androlaelaps fahrenholzi, Gigantolaelaps wolffsohni, Mysolaelaps microspinosus and Mysolaelaps parvispinosus. Laelaps schatzi is reported only for O. flavescens and O. fornesi, while Laelaps paulistanensis was exclusive to O. nigripes, regardless of locality. The results support the view that species reflect the distribution of each host, with the exception of M. parvispinosus. Information on the distribution of ectoparasites and their hosts is relevant to many biological questions, especially when the host and / or the ectoparasite play an important role in the transmission of pathogens of public health importance.

Clostridium piliforme infection (Tyzzer disease) in horses: retrospective study of 25 cases and literature review García, Juan Agustín; Navarro, Mauricio A.; Fresneda, Karina; Uzal, Francisco Alejandro Tyzzer disease (TD) is caused by Clostridium piliforme, a gram-negative and obligate intracellular bacterium. The disease occurs in multiple species. A triad of lesions, namely colitis, hepatitis, and myocarditis, is described in cases of TD in some species, such as rats and mice. We carried out a retrospective analysis of 25 equine cases with a diagnosis of TD; 24 of 25 cases occurred in foals <45 d old; the remaining foal was 90 d old. There were 12 males and 12 females; no sex information was available for one foal. The affected breeds were Quarter Horse, Thoroughbred, Arabian, Paint, and Hanoverian. Most of the cases (19 of 25) occurred in the spring. There were 9 cases of sudden death; the remaining animals had diarrhea, fever, distended abdomen, depression, weakness, non-responsiveness, and/or recumbency. Gross findings included icterus, hepatomegaly with acinar pattern, serosal hemorrhages, pulmonary edema, and/or fluid content in small and large intestine. Microscopically, all foals had severe, multifocal, necrotizing hepatitis. Necrotizing lymphohistiocytic colitis was observed in 10 of 25 foals, and multifocal necrotizing myocarditis was found in 8 of 25. Gram-negative, Steiner-positive, intracytoplasmic filamentous bacteria were observed in hepatocytes, enterocytes, and myocardiocytes, respectively. PCR detected C. piliforme DNA in the liver (24 of 24), colon (20 of 24), and heart (5 of 25). Our results indicate that necrotic hepatitis is the hallmark of TD in horses; the so-called triad of lesions is not a consistent characteristic of the disease in this species.

Scaling laws for nanoporous metals under uniaxial loading Saffarini, Mohammed H.; Voyiadjis, George Z.; Ruestes, Carlos Javier Significant attention in the literature is directed toward the development of scaling relations that relate the properties of nanoporous metals to bulk materials in order to help in their design. Although nanoporous gold has been under extensive study to develop the proper scaling relations, the literature still lacks a specific model that predicts its properties based on a combination of surface parameters, ligament size, and relative density. This work is part of the ongoing trials to introduce such scaling relations. Therefore, utilizing literature-reported results, the authors are proposing scaling relations that account for the coupling effect of surface area to solid volume ratio, ligament size, and relative density to predict the elastic modulus, yield stress, and ultimate stress under uniaxial loading. Moreover, a comparison between the proposed model and existing scaling laws in the literature is presented. Graphic abstract: [Figure not available: see fulltext.]

A Tale of Two Cities: The Tenants' Strikes of 1907-1908 in Buenos Aires and New York: Exploring the Global Historical Roots of Tenants' Organization Poy Piñeiro, Lucas Martín Labor and social historiography paid attention to tenants? strikes throughout history, but comparative studies are still scarce. Case studies are important to help us understand the peculiarities of past struggles, but broader assessments are also critical to evaluate the general trends that shaped working-class resistance in different times and places. Drawing upon a variety of secondary and primary sources, this article examines the tenants? strikes that took place in 1907-1908, with a difference of some months, in Buenos Aires and New York. Although most of the participants were unaware of the events taking place more than 8,500 km away, both strikes had many things in common. Thousands of tenants, many of them migrants, with a strong prominence of women, acted together in order to put an end to the voracious and predatory rule of landlords. They all had to face attacks from the media and the state?they all had to build on their experiences of resistance in order to develop the necessary organizational resources to accomplish their goals. The article focuses on the peculiarities of urban development and working-class formation in both cities, on the motley population that filled its tenement houses and conventillos, on the role played by socialist and anarchist organizers, on the reaction of the state and the ruling class towards the tenants? struggles, and on the prominent role played, in both cases, by migrant workers and women. Its goal is to highlight similarities and differences of these two cases of tenants? strikes, in order to enrich our understanding of the global historical roots of the ongoing struggle against landlords and capitalist market forces.

Un bricolaje de actores y problemas sociales: la sociografía en la Argentina, 1913-1963; A bricolage of actors and social problems: sociography in Argentina, 1913-1963; Uma bricolagem de atores e problemas sociais: a sociografia na Argentina, 1913-1963 Lazarte, Lautaro; González Bollo, Hernán Gustavo La sociografía es el capítulo menos pensado de la historia de la sociología argentina. Fue un trabajo original de conocimiento de lo social, que volcó en el papel actores y problemáticas, como trabajadores no calificados, obreros industriales, empleados, representaciones del mundo rural, clase alta y moradores de villas de emergencia. Esta tarea se desarrolló en medio del dominio de la sociología de cátedra, la universidad bajo el peronismo clásico (1946-1955) y la creación de la carrera de Sociología (UBA, 1957). Estuvo integrada por reformistas sociales, funcionarios e intelectuales del interior argentino, fue legítima precursora de la sociología científica y contiene una variedad de posiciones en el trabajo de campo, estatal y universitario, con sus obras mayores, referentes, preguntas, rutinas, metodologías y logros cognitivos. Este artículo pretende integrar estas perspectivas bajo tres objetivos: a) estudiar a los pioneros y la matriz inicial de temas de la sociografía argentina; b) rastrear su expansión geográfica, más allá del Área Metropolitana de Buenos Aires, en particular, sus impulsores en el noroeste argentino (NOA); c) reconstruir una gama de objetos de mayor formalización, académicos y estadísticos.; Sociography is the least thought of chapter in the history of Argentine sociology. It was an original work of social knowledge, which portrayed on paper the people and the problems, into the paper, such as unskilled workers, industrial workers, employees, representations of the rural world, the upper classes and slum dwellers. This work was developed in the midst of the dominance of professorial sociology, the university under classical Peronism (1946- 1955) and the creation of the Sociology degree (UBA, 1957). It was composed of social reformers, civil servants and intellectuals from the Argentine interior. It was a legitimate precursor of scientific sociology, and contains a variety of positions achieved through fieldwork, and state and academic contributions, that resulted in major works, referents, questions, routines, methodologies and cognitive achievements. This article aims to draw together these perspectives under three objectives: a) to study the pioneers and the initial matrix of topics of Argentine sociography; b) to trace its geographical expansion, beyond the Buenos Aires Metropolitan Area, in particular, its promoters in northwestern Argentina (NOA); c) to reconstruct a range of more formalized, academic and statistical objects.; A sociografia é o capítulo menos pensado da história da sociologia argentina. Foi um trabalho original de conhecimento do aspecto social, que colocou no papel atores e questões, tais como trabalhadores não qualificados, operários de fábricas, empregados, representações do mundo rural, da classe alta e de moradores de favelas. Esta tarefa foi desenvolvida em meio do domínio da sociologia de cátedra, da universidade sob o peronismo clássico (1946-1955) e da criação do curso de Sociologia (UBA, 1957). Composta por reformistas sociais, funcionários e intelectuais do interior argentino, foi precursora legítima da sociologia científica e contém uma variedade de posições no trabalho de campo, estatal e universitário, com suas principais obras, referências, perguntas, rotinas, metodologias e realizações cognitivas. Este artigo visa integrar estas perspectivas sob três objetivos: a) estudar os pioneiros e a matriz inicial de temas da sociografia argentina; b) traçar sua expansão geográfica além da região metropolitana de Buenos Aires e, em particular, seus promotores no noroeste da Argentina (NOA) e c) reconstruir uma série de objetos de maior formalização, acadêmicos e estatísticos.

La corrupción como problema público en la televisión argentina: interacción entre medios y audiencias; Corruption as a social problem in Argentine TV: interaction between media and audiences Zunino, Esteban; Focas, Brenda Marisa La corrupción irrumpió como un problema público en la Argentina durante la década de los noventa, promovido por un conjunto de grupos sociales emergentes que lo instituyeron a partir de estrategias de denuncia. Ya en los años dos mil, el asunto se estabilizó en las agendas mediática y pública, aunque ligada a otros actores, casos y discursos circulantes. El presente trabajo pretende analizar la relación entre la construcción mediática la corrupción y su percepción pública en los cuatro conglomerados urbanos más importantes de Argentina: Área Metropolitana de Buenos Aires (AMBA), Córdoba, Rosario y Mendoza. A partir de un abordaje metodológico que triangula grupos focales desarrollados en las cuatro ciudades y un análisis de contenido sobre las noticias en los noticieros centrales de los canales trece y once de Buenos Aires, diez y ocho de Córdoba, tres y cinco de Rosario y nueve y siete de Mendoza, se pretende analizar cuál es la relevancia mediática y social del problema. Los resultados evidencian una alta importancia del tema en las agendas informativas, sobre todo en las de los medios de Buenos Aires, que presentan una cobertura partisana del problema. En relación con los públicos, el trabajo muestra que, si bien las audiencias expresan cierta distancia y desinterés con estas noticias, se observan procesos de recepción que pululan entre la polarización afectiva y la saturación cognitiva frente al tema.; Corruption emerged as a public problem in Argentina during the 1990, promoted by emerging social groups that instituted it based on reporting strategies. Already in the 2000s, the issue stabilized in the media and public agendas, although linked to other actors, cases, and discourses. This paper aims to analyze the relationship between the media construction of corruption and its public perception in the Argentinian major cities: Buenos Aires, Cordoba, Rosario, and Mendoza. Based on a methodological approach that triangulates focus groups and a content analysis of the central news programs of channels 13 and 11 of Buenos Aires, 10 and 8 of Cordoba, 3 and 5 of Rosario and 9 and 7 of Mendoza, it is intended to analyze the mediatic and social relevance of the problem. Results evidence a high relevance of corruption in the news agendas, especially in those of the Buenos Aires media, which is consistent with some audience’s perceptions. A partisan coverage awakens a polarized and affective reception that affects the processes of victimization. Likewise, the greater visibility of the issue in Buenos Aires raises divergences linked to the geographical variable, both at the level of content and perception. In relation to the public, results show that, although the audiences express a certain distance and disinterest, reception processes are observed that swarm between affective polarization and cognitive saturation.

The circadian clock gates Drosophila adult emergence by controlling the timecourse of metamorphosis Brandon, Mark Thomas; Bustos González, Liliana; Cascallares, Maria Guadalupe; Conejera, Felipe; Ewer, John The daily rhythm of adult emergence of holometabolous insects is one of the first circadian rhythms to be studied. In these insects, the circadian clock imposes a daily pattern of emergence by allowing or stimulating eclosion during certain windows of time and inhibiting emergence during others, a process that has been described as “gating.” Although the circadian rhythm of insect emergence provided many of the key concepts of chronobiology, little progress has been made in understanding the bases of the gating process itself, although the term “gating” suggests that it is separate from the developmental process of metamorphosis. Here, we follow the progression through the final stages of Drosophila adult development with single-animal resolution and show that the circadian clock imposes a daily rhythmicity to the pattern of emergence by controlling when the insect initiates the final steps of metamorphosis itself. Circadian rhythmicity of emergence depends on the coupling between the central clock located in the brain and a peripheral clock located in the prothoracic gland (PG), an endocrine gland whose only known function is the production of the molting hormone, ecdysone. Here, we show that the clock exerts its action by regulating not the levels of ecdysone but that of its actions mediated by the ecdysone receptor. Our findings may also provide insights for understanding the mechanisms by which the daily rhythms of glucocorticoids are produced in mammals, which result from the coupling between the central clock in the suprachiasmatic nucleus and a peripheral clock located in the suprarenal gland.

¿Juramento hipo... qué?: La participación de médicos en el aparato represivo durante la última dictadura cívico militar argentina (1976-1983); Hipocratic Oath ... What? The participation of doctors in the repressive apparatus during the last Argentine civic-military dictatorship (1976-1983) Casartelli, Marina Paola La participación de profesionales de la salud constituyó un elemento central para la concreción y funcionamiento del plan sistemático de exterminio desatado por las Fuerzas Armadas durante la última dictadura cívico militar en Argentina. Desde la atención a las mujeres embarazadas detenidas ilegalmente, la confección de certificados de nacimiento falseados de los bebés nacidos en cautiverio, la participación en sesiones de tortura, entre otros, el accionar de varios médicos demostró su compromiso con los fines del aparato represivo que pretendía aniquilar a un sector de la sociedad calificado como subversivo. En el presente trabajo propongo, a partir de una metodología cualitativa, un análisis de sentencias judiciales con el objetivo de vislumbrar las maneras en que los médicos han servido a los fines del terrorismo de Estado y finalmente condenados en posteriores juicios penales por la comisión de dichos delitos. Este análisis me permitirá indagar en la responsabilidad de los médicos en torno a los crímenes de la dictadura, como también en la manera en que los tribunales han interpretado los mismos. Como se verá a continuación, los delitos en cuestión fueron comprendidos como parte del aparato represivo y, por ello mismo, condenados bajo la figura jurídica de delitos de lesa humanidad.; The participation of health professionals was a central element for the implementation and operation of the systematic plan of extermination unleashed by the Armed Forces during the last civic-military dictatorship in Argentina. From the care of illegally detained pregnant women, the preparation of falsified birth certificates of babies born in captivity, the participation in torture sessions, among others, the actions of several doctors demonstrated their commitment to the aims of the repressive apparatus that was intended annihilate a sector of society, branded as subversive. In the present work I propose, based on a qualitative methodology, an analysis of judicial sentences in order to glimpse the ways in which doctors have served the purposes of State terrorism and finally convicted in subsequent criminal trials for the commission of said crimes. This analysis will allow me to inquire into the responsibility of doctors regarding the crimes of the dictatorship, as well as the way in which the courts have interpreted them. As will be seen below, the crimes in question were understood as part of the repressive apparatus and, for this reason, were condemned under the legal status of crimes against humanity.

Nouvelles pratiques de mobilité active et collective dans la ville de Buenos Aires; Prácticas emergentes de movilidad activa y colectiva en la ciudad de Buenos Aires Di Virgilio, Maria Mercedes; Ramos Mancilla, Oscar Des pratiques de mobilité active naissent dans la ville de Buenos Aires : il s’agit de promenades collectives à pied ou en bicyclette. Ces pratiques font partie de l’ensemble d’alternatives à la mobilité quotidienne, mais leurs caractéristiques spécifiques rendent possibles d’autres sortes d’interactions et d’échanges liés aux environnements urbains. Ce travail propose une approche ethnographique de ces pratiques pour comprendre leur insertion dans le cadre plus vaste des courants et des déplacements et pour identifier la capacité d’action des personnes participant aux promenades dans les transformations de la ville.; En la ciudad de Buenos Aires, están emergiendo prácticas de movilidad activa. Se trata de paseos colectivos que se realizan a pie o en bicicleta. Estas prácticas forman parte del conjunto de alternativas para la movilidad cotidiana pero, por sus características específicas, posibilitan otro tipo de interacciones e intercambios vinculados a los entornos urbanos. En este trabajo, realizamos un acercamiento etnográfico a estas prácticas para comprender las maneras en las que se insertan en el marco más amplio de los flujos y desplazamientos, y para identificar la capacidad de agencia en las transformaciones de la ciudad de las personas que participan en los paseos.

Nuevas reglas sobre la investigación de accidentes de aviación en la Argentina. Su articulación con el Código Aeronáutico y el Anexo 13; new rules on the investigation of aviation accidents in argentina. How they tie in with the aeronautical code and annex 13 Capaldo, Griselda Delia Los bajos índices de siniestralidad registrados en el transporte aéreo se deben a la investigación sistemática de los accidentes sufridos por la aviación civil, tanto doméstica como mundial. Esa investigación técnica está sujeta a un amplio abanico de normas nacionales e internacionales. El propósito de este trabajo es analizar el sistema legal vigente en Argentina, sobre todo a partir de la última ley sobre seguridad en el transporte, y compararla con las normas recomendadas por la Organización de Aviación Civil Internacional. Se incluyen someras referencias a los organismos de un número selecto de países, escogidos al azar entre varios, que tienen a su cargo la tarea de investigar los accidentes aeronáuticos.; The low accident rates in air transport are a consequence of the systematic investigation of accidents registered by civil aviation, at both domestic and global levels. That technical inquiry is governed by a wide range of national and international rules and standards. The purpose of this work is to analyze the current legal system in Argentina, especially from the latest law on transport safety, and to compare it with the standards recommended by the International Civil Aviation Organization. Additionally, brief references to agencies in charge of investigating aircraft accidents in a select number of countries —randomly chosen— are also included.

I dannati della terra: The italian left facing the third world on the eve of 1968 Mestman, Mariano Ernesto The Italian film I dannati della terra (The Damned of the Earth) (Orsini and Filippi 1968) is a prominent example of the connection between the European cinema of intervention and the Third World struggles of the 1960s. Set as a ‘film within a film’, the movie tells the story of a leftist filmmaker, Fausto Morelli, who faces the challenge of finishing a film about the liberation struggles of sub-Saharan Africa by building on the documentary footage that was bequeathed to him by his student and friend, the young Abramo Malonga, an African (Bantu). This article recovers overlooked and little-known documents about the film to show that it is the expression of an active cinematic Third Worldism forged in previous years between the legacy of the Resistenza Partigiana (Italian Resistance) and the Third World struggles of the 1960s. At the same time, the article analyses the ways in which the film ‘dialogues’ with experimental trends of the contemporary avant-garde artistic scene in order to challenge the viewer to debate the ‘open ideological hypothesis’ of the film and take an active part in the political struggles of the time.

Multimodal neurocognitive markers of frontal lobe epilepsy: Insights from ecological text processing Moguilner, Sebastian Gabriel; Birba, Agustina; Fino, Daniel; Isoardi, Roberto Andrés; Huetagoyena, Celeste; Otoya, Raúl; Tirapu, Viviana; Cremaschi, Fabian; Sedeño, Lucas; Ibáñez, Agustín; García, Adolfo Martín The pressing call to detect sensitive cognitive markers of frontal lobe epilepsy (FLE) remains poorly addressed. Standard frameworks prove nosologically unspecific (as they reveal deficits that also emerge across other epilepsy subtypes), possess low ecological validity, and are rarely supported by multimodal neuroimaging assessments. To bridge these gaps, we examined naturalistic action and non-action text comprehension, combined with structural and functional connectivity measures, in 19 FLE patients, 19 healthy controls, and 20 posterior cortex epilepsy (PCE) patients. Our analyses integrated inferential statistics and data-driven machine-learning classifiers. FLE patients were selectively and specifically impaired in action comprehension, irrespective of their neuropsychological profile. These deficits selectively and specifically correlated with (a) reduced integrity of the anterior thalamic radiation, a subcortical structure underlying motoric and action-language processing as well as epileptic seizure spread in this subtype; and (b) hypoconnectivity between the primary motor cortex and the left-parietal/supramarginal regions, two putative substrates of action-language comprehension. Moreover, machine-learning classifiers based on the above neurocognitive measures yielded 75% accuracy rates in discriminating individual FLE patients from both controls and PCE patients. Briefly, action-text assessments, combined with structural and functional connectivity measures, seem to capture ecological cognitive deficits that are specific to FLE, opening new avenues for discriminatory characterizations among epilepsy types.

Geometric morphometrics reveal complex shape variation patterns at different geographic scales in the patagonian gastropod Trophon geversianus Nieto Vilela, Rocío Aimé; Vrdoljak, Juan Esteban; Giulianelli, Sebastian Jesus; Bigatti, Gregorio; Marquez, Federico Environments with strong gradients in physical conditions, such as rocky intertidal, induce animal morphological strategies to face them. The gastropod Trophon geversianus inhabit within the intertidal and subtidal habitats of Patagonian rocky shores. Although there is a wide knowledge of the phenotypic differences of this species regarding habitats (i.e., intertidal/subtidal), little is known about the interaction between habitat and latitude. Here, we studied form variation (size and shape) by using 3D geometric morphometric of T. geversianus shells from alive gastropods and analyzed the phenotypic effect from micro-scale(habitat), macro-scale (latitude), and the interaction habitat-latitude (site). Lastly, we tested the classification accuracy of the shape variable for each predictor variable and a synthetic variable (from a cluster analysis). We found that habitats and sites had the greatest influence on shape variation. Moreover, we found that the largest shell sizes were more likely to be located in subtidal habitats. Also, the size differences between sites were not negligible. Finally, habitat demonstrated the highest classification accuracy for shape, even higher than genetically determined (sex) and synthetic variables. We found that the gastropods from the intertidal habitat presented a globular morph with shorter spire and larger relative size of the shell aperture, while subtidal gastropod showed an elongated morph, with smaller aperture and longer spire. We present evidence of the complexity of size and shape variation in T. geversianus, highlighting that site-dependence on shape variation must be considered in geometric morphometrics studies at a latitudinal scale.

Kartographie der Gegenoffensive: Das Gespenst des Feminismus; Cartography of the Counteroff ensive: The specter of feminism Gago, Maria Veronica Die feministischen Bewegungen weltweit und die sich darin artikulierenden Feminismen fordern die etablierten Mächte heraus, und diese haben eine dreifache – kirchliche, ökonomische und militärische – Gegenoff ensive entfacht, gestützt unter anderem auf die öff entliche Verurteilung der ›Gender-Ideologie‹. Dabei werden verschiedene Taktiken genutzt. So wird die ›Gender-Ideologie‹ mit dem Kolonialismus verknüpft oder der Feminismus als triviale Politik der Mittelklasse infantilisiert und den allgemeinen Nöten großer Teile der Bevölkerung entgegengestellt.; Feminist movements around the world and the feminisms articulated within them are defying the established powers. Th e latter have unleashed a counter-off ensive based, among other things, on the public condemnation of ‘gender ideology’. Various tactics are used to achieve this. For example, ‘gender ideology’ is linked to colonialism, or feminism is infantilised as a trivial middle-class policy and set against the general needs of large parts of the population.

La significatividad del ciclo del agua: un camino para explorar modos de construir una educación científica intercultural; The significance of water cycle: exploring ways to build an intercultural scientific education; O significado do ciclo da água: exploração de maneiras de construir uma educação científica intercultural Bonan, María Leonor; Bonanata, Julieta; Gonzalez, Maria Lorena; Pittaro, Ana; Chadwick, Geraldine; Azpiazu Garrido, Santiago Martín El presente artículo de investigación presenta parte de los resultados de un proyecto desarrollado por el Grupo de Investigación en Educación Científica Intercultural (Grupo ieci) del Instituto cefie de la Facultad de Ciencias Exactas y Naturales (fcen) de la Universidad de Buenos Aires (uba). Para su realización se intervino en algunas instituciones educativas a las que asisten estudiantes, mayoritariamente, del pueblo originario qom. Siendo parte de una investigación-acción sobre Educación Científica Intercultural (eci), el objetivo específico de este trabajo fue encontrar puntos de contacto o vínculos entre conocimientos científicos y vernáculos, mediante una temática común; con este fin, se decidió trabajar con una comunidad qom de las provincias de Chaco y Formosa, Argentina. Asimismo, se diseñaron una serie de actividades didácticas exploratorias con la intención de develar la aparición de componentes culturales científicos y vernáculos sobre el agua, uno de los elementos más importantes para la vida humana. Esto se desarrolló al poner en diálogo tres relatos ancestrales donde intervinieron distintos seres de la cultura qom relacionados con el tópico elegido y los procesos que atraviesa el agua desde la mirada de la ciencia escolar. Parte de los objetivos generales de la investigación fueron la creación de materiales didácticos interculturales para generar conciencia de la diversidad cultural que integra nuestra sociedad.; This work presents part of the research results of the Research Group in Intercultural Scientific Education (ise Group) of the cefie Institute of the Faculty of Exact and Natural Sciences (fens) of the University of Buenos Aires (uba). To develop this process, some educational institutions that are attended by students from the qom native people, were intervened by the investigators. Being part of an action research on Intercultural Scientific Education (eci), its specific objective was to find points of contact or links between scientific knowledge and vernacular through a common theme in a qom community of Chaco and Formosa provinces, Argentina. A series of exploratory didactic activities were designed in such a way as to reveal the appearance of scientific cultural components and vernacular on water, one of the most important elements for human life. Starting from putting into dialogue three ancient stories where different beings from the qom culture intervene related to the chosen topic and the processes that water goes through from the school science point of view. Part of the general research is the creation of intercultural teaching materials to raise awareness of the cultural diversity that integrates our society.; Este artigo apresenta parte dos resultados da pesquisa do Grupo de Pesquisa em Educação Científica Intercultural (Grupo peci) do Instituto cefie da Faculdade de Ciências Exatas e Naturais (fcen) da Universidade de Buenos Aires (uba). Realizou-se em instituições educacionais frequentadas por estudantes, principalmente, da etnia qom. Como parte de uma pesquisa-ação sobre Educação Científica Intercultural (ice), o objetivo específico era encontrar pontos de contato ou vínculos entre o conhecimento científico e o vernáculo por meio de um tema comum. Para esse fim, decidiu-se trabalhar com uma comunidade qom das províncias de Chaco e Formosa, Argentina. Da mesma forma, uma série de atividades didáticas exploratórias foi projetada de forma a revelar componentes culturais científicos e vernaculares na água, um dos elementos mais importantes para a vida humana. Começou-se por analisar comparativamente três histórias antigas em que diferentes seres da cultura qom, relacionados ao tópico escolhido e aos processos pelos quais a água passa do ponto de vista da ciência escolar, intervêm. Parte da pesquisa geral é a criação de materiais interculturais de ensino para aumentar a conscientização sobre a diversidade cultural que integra nossa sociedade.

El voto transnacional de los grupos migrantes en Argentina Cruset, Maria Eugenia; Silva, María Paz; Malagamba, María Lara Los nuevos estudios en ciencias sociales han permitido entender los procesos migratorios como fenómenos dinámicos que no se circunscriben a las fronteras de los Estados nación y que dan una proyección de acción en origen y en destino a los grupos migrantes. Esto nos lleva a reformular conceptos tradicionales como el de ciudadanía política. En este trabajo, analizaremos el voto transnacional de los inmigrantes italianos, croatas y paraguayos en la Argentina.; New studies in Social Sciences have allowed us to understand migratory processes as dynamic phenomena that are not circumscribed to the borders of nation-states and that give a projection of action in origin and destination to migrant groups. This leads us to reformulate traditional concepts such as political citizenship. In this paper we will analyze the transnational vote of Italian, Croatian and Paraguayan immigrants in Argentina.

Evaluación de la memoria emocional en niños: metodologías y problemas éticos; Evaluation of emotional memory in children: methodologies and ethical problems Jaume, Luis Carlos; Gago Galvagno, Lucas Gustavo; Elgier, Angel Manuel; Azzollini, Susana Celeste La investigación de la memoria emocional lleva ya algunas décadas de prolíficos estudios publicados, estudiando a adultos y niños. Muchos de los estudios que evalúan la memoria emocional en niños incluyen la evocación de recuerdos relacionados con emociones estresantes o aversivas. Este estudio propone examinar las metodologías utilizadas en estudios de memoria emocional con niños, analizando cuáles aspectos han sido poco estudiados en la literatura sobre esta temática. Se concluye problematizando aspectos sobre la metodología y la ética en los estudios existentes sobre la memoria emocional en niños y evaluando posibles direcciones para las futuras investigaciones.; All-Research on emotional memory has been growing for several decades now, studying both adults and children. Many of the studies assessing emotional memory in children include the evoking of memories related to stressful or aversive emotions. This study proposes to examine the methodologies used in studies of emotional memory with children, analyzing which aspects have not been widely studied in the literature on this subject. It concludes by problematizing aspects of methodology and ethics in existing studies of emotional memory in children and evaluating possible directions for future research.

Información dura-pública y blanda-privada publicada por candidatos y candidatas en Instagram durante la campaña electoral en Argentina 2019; Hard-public information and soft-private information posted by candidates on Instagram during the 2019 Argentinian electoral campaign García Beaudoux, Virginia Inés; Slimovich, Ana En este artículo se presentan los resultados de una investigación que explora las características de las publicaciones efectuadas en Instagram por candidatos y candidatas a cargos electivos en Argentina durante la campaña para las elecciones 2019. Se analizó la proporción de información dura-pública e información blanda-privada o politainment que publicaron, y qué tipo de publicación recibió más likes. Los resultados indican la necesidad de redefinir las categorías analíticas “información dura” e “información blanda” tal como se las utiliza actualmente para estudiar este tipo de fenómenos de comunicación política.; This paper presents the results of a research that explores the main features of Instagram publications of the candidates that participated in the electoral campaign that took place in Argentina in 2019. The proportion of hard-public information and soft-private information or politainment was analyzed, as well as which type of publications received more “likes”. The results indicate the need to redefine the analytical categories hard information and soft information as they are currently used to study political communication phenomena.

Protección social, políticas de cuidados y discapacidad para personas mayores: Argentina 2016-2020; Social protection, care and disability policies for the elderly: Argentina 2016-2020 Venturiello, María Pía; Cirino, Estefanía Claudia; Palermo, María Cecilia El elevado envejecimiento demográfico acompañado de un sostenido crecimiento de la discapacidad son fenómenos que influyen en las transferencias intergeneracionales, en el aumento de la demanda de los servicios de salud y de cuidados de larga duración y en las políticas de previsión social para las personas mayores. Este escenario plantea desafíos sociales y políticos a nivel estatal: ¿se cumplen las leyes de protección integral para las personas con discapacidad? ¿Cómo afectan las reformas previsionales en la situación de los jubilados y pensionados actuales y futuros? ¿Qué rupturas y continuidades se encuentran entre las políticas públicas llevadas a cabo en los últimos dos gobiernos del país? En un contexto de fragmentación de las políticas de protección social, las estrategias del Estado dirigidas hacia personas mayores y hacia personas con discapacidad no conforman un sistema integral y continuo. Esto se refleja en las medidas tomadas en las últimas dos gestiones de gobierno encabezadas por Mauricio Macri (2016-19) y Alberto Fernandez (2019-en curso). En el contexto actual de pandemia por Covid-19, estas cuestiones se han visto agravadas al construirse mecanismos que implican una desprotección sobre los derechos de los ciudadanos de estos grupos. En este trabajo se analizan las transformaciones acaecidas en las políticas de protección social en Argentina referidas a previsión social, salud y cuidados para las personas de 60 años y más y con alguna discapacidad, describiendo las principales medidas implementadas durante estos gobiernos. El interés se centra en describir las normativas teniendo en cuenta continuidades y/o rupturas destinadas a dicha población. La metodología se basa en el relevamiento de fuentes secundarias (leyes y decretos, revisión bibliográfica, análisis de encuestas poblacionales, rastreo de diarios nacionales).; The high demographic aging accompanied by a sustained growth in disability. These are phenomena that influence intergenerational transfers, the increase in demand for health and long-term care services, and social security policies for the elderly. This scenario poses social and political challenges at the state level: are the comprehensive protection laws for people with disabilities being complied with? How do pension reforms affect the situation of current and future retirees and pensioners? What breaks and continuities are found between the public policies carried out in the last two governments of the country? In a context of fragmentation of social protection policies, the State's strategies aimed at the elderly and people with disabilities do not make up a comprehensive and continuous system.
