Un cuento de tres zorros… Lycalopex gymnocercus (Fischer, 1814), L. culpaeus (Molina, 1972) y Cerdocyon thous (Linnaeus, 1766) en La Rioja, República Argentina, ¿coincidencia o simpatría?; A tale of three foxes… Lycalopex gymnocercus (Fischer, 1814), L. culpaeus (Molina, 1972) and Cerdocyon thous (Linnaeus, 1766) in La Rioja, Argentina, coincidence or sympatry? Fariñas Torres, Thamara; Chemisquy, Maria Amelia En este trabajo se presenta el primer registro de una posible distribución simpátrica entre tres especies de zorros, el zorro cangrejero Cerdocyon thous, el zorro colorado Lycalopex culpaeus y el zorro gris L. gymnocercus, obtenido mediante el uso de trampas cámara y observación directa en el valle de Huaco, provincia de La Rioja, Argentina. Estos registros resaltan la importancia de realizar relevamientos de fauna en zonas poco estudiadas de Argentina.; This work presents the first record of a possible sympatric distribution of three species of foxes, the crab-eating fox (Cerdocyon thous), the Andean fox (Lycalopex culpaeus), and the Pampas fox (L. gymnocercus) which was obtained through the use of camera traps and direct observation in the Huaco Valley, Province of La Rioja, Argentina. These records once again highlight the importance of conducting faunal surveys in poorly studied areas of Argentina.

Nanomedicines against Chagas disease: A critical review Morilla, María José; Ghosal, Kajal; Romero, Eder Lilia Chagas disease (CD) is the most important endemic parasitosis in South America and represents a great socioeconomic burden for the chronically ill and their families. The only currently available treatment against CD is based on the oral administration of benznidazole, an agent, developed in 1971, of controversial effectiveness on chronically ill patients and toxic to adults. So far, conventional pharmacological approaches have failed to offer more effective and less toxic alternatives to benznidazole. Nanomedicines reduce toxicity and increase the effectiveness of current oncological therapies. Could nanomedicines improve the treatment of the neglected CD? This question will be addressed in this review, first by critically discussing selected reports on the performance of benznidazole and other molecules formulated as nanomedicines in in vitro and in vivo CD models. Taking into consideration the developmental barriers for nanomedicines and the degree of current technical preclinical efforts, a prospect of developing nanomedicines against CD will be provided. Not surprisingly, we conclude that structurally simpler formulations with minimal production cost, such as oral nanocrystals and/or parenteral nano-immunostimulants, have the highest chances of making it to the market to treat CD. Nonetheless, substantive political and economic decisions, key to facing technological challenges, are still required regarding a realistic use of nanomedicines effective against CD.

Ostracods from the Cretaceous–Palaeogene boundary at El Matuasto Section, Neuquén Basin, Argentina: taxonomy, palaeoecological and palaeobiogeographical inferences Ceolin, Daiane; Santos Filho, Marcos Antonio B.; Concheyro, Graciela; Fauth, Gerson This work presents a taxonomic, palaeoecological and palaeobiogeographical study of the ostracod fauna around the Cretaceous–Palaeogene boundary from the El Matuasto section, Neuqu en Basin, Argentina. The analysis of 64 samples resulted in the recovery of 82 marine ostracod species, of which four are new: Hemiparacytheridea condilomata, Paramunseyella stictus, Hysterocythereis acuminata and Aleisocythereis? picnus. In addition, the genera Sapucariella, Monoceratina, Aracajuia, Microceratina and Pelecocythere are reported for the first time from the Neuqu en Basin. Palaeoecological inferences indicate fluctuations in abundance and diversity, occurring alongside environmental change from an inner to medium shelf during the Maastrichtian and to an outer shelf in the Danian. The Maastrichtian fauna was less abundant than that in the Danian, which shows a rapid recovery after the Cretaceous–Palaeogene boundary. During the Danian, a small interval also shows a sudden decrease in abundance and diversity that could potentially be related to the Dan-C2 event. In addition, the described genera and species in this study suggest a strong palaeobiogeographical affinity with the Para ıba Basin, northeastern Brazil.

Epistemic Decentering: Toward a More Equitable Pedagogy Levitt, Peggy; Rutherford, Markella; Saferstein, Ezequiel Andres To date, most post- and decolonial responses to inequality in cultural and intellectual institutions have focused on regaining control over “theory” and epistemology. Alexander’s reflection urges us to expand the boundaries of the battleground. Diversifying content is important. But that will not do the trick if it is not accompanied by a range of other shifts in how we engage with these materials and with one another—in the institutions where we study and work, and in the disciplinary infrastructures that organize our work. To make more meaningful progress toward intellectual and cultural equality, we need to decenter how we listen, smell, feel, and touch as well as how we see. We need to decenter our pedagogical and scholarly relationships. This article lays out why that urgently matters and offer concrete suggestions for moving forward.

La Banda de la Policia de San Juan (Argentina) como agente de difusión popular de la ópera; The San Juan Police Band (Argentina) as an agent for the popular diffusion of opera Gerico, Yanet Hebe A través de diversas mediaciones la ópera circuló por distintos espacios por fuera del teatro. Este trabajo hace foco en la banda como agente de difusión popular del género lírico. Específicamente, aborda la inclusión de arreglos musicales basados en fragmentos operísticos en el repertorio de la Banda de Policía de San Juan (Argentina) durante la primera mitad del siglo XX y busca contextualizar su ejecución en retretas realizadas al aire libre. Para ello, el estudio profundiza en estos eventos como espacio de sociabilidad, en la relación de la agrupación con la audiencia y en los modos en que la prensa periódica moldeó ese vínculo.Se detalla el trabajo de relevamiento y clasificación de los arreglos musicales de ópera localizados en el Archivo Histórico de la Banda de Policía de San Juan. Las fuentes empleadas incluyen artículos hemerográficos y partituras musicales manuscritas e impresas existentes en el mencionado repositorio.Tomando a San Juan como sociedad receptora de este género migrante, estas creaciones ad hoc se consideran como una de las modalidades de adaptación de las obras originales a las especificidades del conjunto y a las necesidades y prácticas de consumo locales. Esta investigación permite avanzar en el estudio de los efectos de la recepción socio-estética de la ópera llegada a nuestro país gracias a la inmigración y a la itinerancia de compañías europeas.; Opera circulated in different spaces outside the theater. This paper focuses on bands as agents that contributed to the dissemination of this lyrical genre. Specifically, it analyzes the inclusion of musical arrangements based on operatic fragments in the repertoire of the Police Band of San Juan (Argentina) during the first half of the twentieth century and seeks to contextualize their performance in open-air events. In this sense, the study delves into these events as a space for sociability, in the relationship between the band and the audience, and the ways in which the press shaped this link. This paper also let us show our classification of opera musical arrangements located in the Historical Archive of the San Juan Police Band. We understand that these ad hoc creations have been adapted to the specificities of the ensemble and to local needs and consumption practices. The sources studied here include newspaper articles, as well as manuscript and printed musical scores. This research allows us to continue studying the effects of the socio-aesthetical reception of opera in Argentina thanks to immigration and the itinerancy of Italian opera companies.

The State of Open Science Practices in Psychometric Studies of Suicide: A Systematic Review Flores Kanter, Pablo Ezequiel; Alvarado, Jesus M. The adoption of open science practices (OSPs) is crucial for promoting transparency and robustness in research. We conducted a systematic review to assess the frequency and trends of OSPs in psychometric studies focusing on measures of suicidal thoughts and behavior. We analyzed publications from two international databases, examining the use of OSPs such as open access publication, preregistration, provision of open materials, and data sharing. Our findings indicate a lack of adherence to OSPs in psychometric studies of suicide. The majority of manuscripts were published under restricted access, and preregistrations were not utilized. The provision of open materials and data was rare, with limited access to instruments and analysis scripts. Open access versions (preprints/postprints) were scarce. The low adoption of OSPs in psychometric studies of suicide calls for urgent action. Embracing a culture of open science will enhance transparency, reproducibility, and the impact of research in suicide prevention efforts.

Ontología procesual de la enfermedad e identidad personal; Process Ontology of Illness and Personal Identity Córdoba, Mariana; Alassia, Fiorela Romina; Perez Marc, Gonzalo En el presente artículo nos proponemos argumentar en favor de una concepción procesual de la identidad de la persona enferma. Para ello, recorreremos algunas de las principales respuestas que ha dado la filosofía a la pregunta por la identidad personal, así como ciertas propuestas sobre cómo concebir la enfermedad y la identidad de la persona enferma. A partir de la adopción de un enfoque procesual de la ontología, pondremos el foco en una interpretación procesual-relacional no dualista de los organismos biológicos.; In this paper, it is our purpose to argue for a processual conception of ill-person- identity. To do so, we will review some of the main answers that philosophy has given to the question of personal identity. We will review certain proposals on how to conceive illness and ill-person-identity, as well. Within the frame of a processual approach to ontology, we will focus on a non-dualistic processual-relational interpretation of biological organisms.

O prédio de 336 m2 faz parte de uma rede de centros infantis construídos nos últimos anos em vários municípios. Foram instalados instrumentos para monitorar o comportamento higrotérmico interno e uma estação meteorológica na área externa; foram realizadas pesquisas de percepção ambiental com os funcionários; o consumo de energia foi registrado juntamente com o levantamento dos equipamentos e a materialização de sua envoltória; foram analisados os históricos de consumo e as termografias. O objetivo era obter um conhecimento profundo de seu comportamento para propor possíveis medidas de reabilitação para melhorar sua eficiência energética. Os resultados são apresentados, juntamente com recomendações de intervenção para sua sustentabilidade.; With funding from a Euroclima+ project, a winter and summer audit of a high social impact building in a vulnerable area of the AMBA was carried out. The 336 m2 building is part of a network of children's centers built in recent years in several municipalities. Instruments were installed to monitor indoor hygrothermal behavior and a weather station was installed outside, environmental perception surveys were conducted with employees, energy consumption was recorded together with the survey of the equipment and materialization of its envelope, historical consumption and thermographs were analyzed. The aim was to obtain a thorough knowledge of their behavior in order to propose possible rehabilitation measures to improve their energy efficiency. The results are presented, together with recommendations for intervention for its sustainability.

El encanto de un final; The charming of an ending Topuzian, Marcelo El trabajo, en primer lugar, analiza un recurso de evaluación característico e institucionalizado en la cátedra de Teoría y Análisis Literario ‘C’ de la carrera de Letras de la Universidad de Buenos Aires: el examen o coloquio final. Se tienen especialmente en cuenta –además de su carácter oral– su masividad, la implicación en él de los docentes auxiliares y, sobre todo, el propósito de síntesis personal que lo guía. A continuación, se exploran las actitudes respecto de la teoría literaria como disciplina y como corpus que pueden desprenderse de esta concepción de la evaluación: una presentación que es histórica y que incluso no esquiva pensar su eventual –o actual– clausura (el tópico del ‘fin de la teoría’), pero que también busca enfatizar su conexión con el presente más inmediato y también, por qué no, con el futuro. En este último sentido se discute el rol de la cátedra en la difusión en Argentina de los estudios culturales, especialmente en relación con las perspectivas sobre los mismos provenientes de las ciencias sociales. Se llama finalmente la atención sobre los presupuestos políticos que orientan estas actitudes y se extraen conclusiones a propósito del rol de la teoría literaria en la formación superior en los estudios literarios, en tiempos de completa rehabilitación de los enfoques históricos sobre la literatura.; The paper, first of all, analyzes a characteristic and institutionalized evaluation resource in the Literary Theory and Analysis ‘C’ course of the Literature Department of the University of Buenos Aires: the final exam or colloquium. In addition to its oral character, its massiveness, the involvement of teaching assistants in it and, above all, the purpose of personal synthesis that guides it are especially taken into account. Next, we explore the attitudes towards literary theory as a discipline and as a corpus that can be derived from this conception of evaluation: a presentation that is historical and that does not even avoid thinking about its eventual -or actual- closure (the topic of the ‘end of theory’), but that also seeks to emphasize its connection with the most immediate present and also, why not, with the future. In this last sense, the role of the course in the diffusion of cultural studies in Argentina is discussed, especially in relation to the perspectives on them coming from the social sciences. Finally, attention is drawn to the political assumptions that guide these attitudes and conclusions are drawn about the role of literary theory in higher education in literary studies, in times of complete rehabilitation of historical approaches to literature.

Discursividades disidentes, fronteras enunciativas y espacios de decir periféricos: Reflexiones sobre el lenguaje no sexista, el lenguaje inclusivo y los discursos con perspectiva de género; Dissident discursiveness, enunciative frontiers and outlying speech spaces: Reflections on non-sexist language, inclusive language and discourses with gender perspective Tosi, Carolina Luciana; Hermida, Maria Eugenia Este trabajo presenta la continuación del dosier “Discursividades disidentes. Reflexiones sobre el lenguaje no sexista, el lenguaje inclusivo y los discursos con perspectiva de género” (publicado en el volumen VII, número 2 de esta revista). El presente dosier se configura como un espacio de diálogo en torno a las prácticas vinculadas con la perspectiva de género y como un marco para la indagación de los rasgos que caracterizan las nuevas construcciones discursivas, las disputas que generan y las posibilidades de reflexión en pos de contribuir con los actuales debates en el área de las ciencias sociales y humanísticas. Los artículos que recopila y pone en diálogo esta segunda entrega se centran en explorar las lógicas, las trampas y las oportunidades relativas a un habla otra, pero ya no en los sitios habituales o hegemónicos. Por el contrario, los cuatro textos ponen el foco en analizar prácticas discursivas producidas en espacios alternativos y logran construir un archivo otro, en el que se entrecruzan el lenguaje inclusivo, la Educación Sexual Integral, los feminismos y las disidencias sexogenéricas. Se trata de investigaciones, realizadas en Argentina, Chile y Brasil, que nos invitan a adentrarnos en espacios de decir periféricos y traspasar las fronteras enunciativas impuestas por las matrices discursivas de poder.; This work presents the second issue of the dossier “Dissident discursiveness. Reflections on non-sexist language, inclusive language and discourses with gender perspective” (published in this review, in Volume VII, Issue 2). The present dossier constitutes a space for dialogue about the discursive practices related to the gendered perspective, as well as a frame for inquiring in the features of new discursive constructions, the disputes that they arise and the possibilities that they offer to think and contribute to the present debates in the various disciplines of the Social Sciences and the Humanities. The articles gathered in this issue explore the logics, the traps and the opportunities related to an outlying speech in contexts which are not considered hegemonic. As a result, the dossier presents an alternative archive of inclusive language, sexual education, feminisms and dissident sexual identities, that reveals practices and resistances in Argentina, Chile and Brazil.

Disparate response of decapods to low pH: A meta-analysis of life history, physiology and behavior traits across life stages and environments Ocampo, Emiliano Hernan; Nuñez, Jesus Dario; Ribeiro, Pablo Damián; Pérez García, Macarena; Bas, Claudia Cristina; Luppi, Tomas Atilio We employed a meta-analysis to determine if the presumed resilience of decapods to ocean acidification extends to all biological aspects, environments, and life stages. Most response categories appeared unaffected by acidification. However, certain fitness-related traits (growth, survival, and, to some extent, calcification) were impacted. Acid-base balance and stress response scaled positively with reductions in pH, which maintains homeostasis, possibly at the cost of other processes. Juveniles were the only stage impacted by acidification, which is believed to reduce recruitment. We observed few differences in responses to acidification among decapods inhabiting contrasting environments. Our meta-analysis shows decapods as a group slightly to moderately sensitive to low pH, with impacts on some biological aspects rather than on all specific life stages or habitats. Although extreme pH scenarios may not occur in the open ocean, coastal and estuarine areas might experience lower pH levels in the near to medium future, posing potential challenges for decapods.

Trophic ecology of Geoffroy's cat (Leopardus geoffroyi) and mammal prey availability in semi-arid environments of central Patagonia, Argentina; Ecología trófica del gato montés (Leopardus geoffroyi) y disponibilidad de presas de mamíferos en ambientes semiáridos de la Patagonia central, Argentina D´Agostino, Romina Laura; Udrizar Sauthier, Daniel Edgardo Research on the dietary composition of felids can help improve the perception of rural workersand their tolerance towards this group, which is threatened by human-wildlife conicts. In this context, the purpose of this study was to quantify the diet of Leopardus georoyi in Península Valdés (Patagonia, Argentina) to obtain baseline knowledge of the species dietary habits, trophic ecology, and degree of prey consumption. To this end, 160 fresh scat samples, collected from 2013 to 2016, were analyzed. Ten mammal species, one tinamou bird, one lizard genus, and one insect order were identied. The most frequently consumed prey (63.84%) were small-sized mammals (< 1 kg), accounting for the highest biomass contribution (37.2%). The frequency of each mammal species in the diet was not correlated with their capture frequency (measured through Sherman live traps and pedestrian diurnal transects). This study is the rst to report on the diet of L. georoyi in Argentinean central Patagonia, and it provides information not only on ecological aspects but alsoon the natural history of this felid species.; La investigación sobre la composición de la dieta de los felinos puede ayudar a mejorar la percepción y la tolerancia de los trabajadores rurales hacia esta especie de carnívoro felino que se ve amenazada por el con icto entre humano-vida silvestre. En este contexto, el propósito de este estudio fue cuanti car la dieta de Leopardus geo royi en Península Valdés (Patagonia, Argentina) con la nalidad de obtener un conocimiento básico sobre la ecología tró ca y el grado de consumo de presas. Para ello, se analizaron 160 muestras de heces frescas recogidas entre 2013 y 2016. Se identi caron 10 especies de mamíferos, una especie de tinamú, un género de lagarto y un orden de insecto. Se encontró que las presas consumidas con mayor frecuencia (63.84%) eran los mamíferos de pequeño tamaño (< 1 kg) que, a su vez, representaron la mayor contribución de biomasa (37.2%). La frecuencia de cada especie de mamífero en la dieta no se correlacionó con su frecuencia de captura (medida a través de trampas de captura viva tipo Sherman y transectos diurnos pedestres). Este trabajo es la primera aproximación a la dieta de L. geoffroyi realizada en la Patagonia central argentina y aporta conocimientos no solo sobre aspectos ecológicos, sino también sobre la historia natural de esta especie de felino.

Contextos institucionales de las mujeres candidatas a gobernadoras en las provincias argentinas (1983-2019); Institutional contexts of women candidates for governors in the Argentine provinces (1983-2019) Berman, Luciana Este artículo busca avanzar en la comprensión sobre la participación política-electoral de las mujeres en las elecciones ejecutivas en las 23 provincias argentinas y la Ciudad Autónoma de Buenos Aires entre 1983 y 2019. A partir de la reconstrucción de las 1.878 candidaturas en 236 comicios provinciales durante 36 años de democracia ininterrumpida y del análisis de los regímenes electorales y sus modificaciones, se analizan los contextos institucionales en los que las mujeres participaron en elecciones como candidatas a gobernadoras o a vicegobernadoras. Se toman las constituciones provinciales para determinar el régimen electoral, las reformas políticas y constitucionales y las leyes que, específicamente, tengan que ver con la participación electoral de las mujeres, con el objetivo de encontrar si esas leyes refieren a las candidaturas ejecutivas. Los hallazgos principales muestran que no hubo un efecto derrame que incorporara mujeres como candidatas a los ejecutivos a partir de las leyes de cuotas y de paridad legislativas, dado que el porcentaje de participación fue bajo durante todo el período en todas las provincias y para ambos cargos en competencia, sobre todo para la Gobernación.; Ths article seeks to advance the understanding of women’s political and electoral participation in the executive elections in the 23 Argentinian provinces and the Autonomous City of Buenos Aires between 1983 and 2019. Starting from the reconstruction of the 1878 candidatures in 236 provincial elections during 36 years of uninterrupted democracy and the analysis of the electoral regimes and their modifications, the institutional contexts in which women participated in elections as candidates for governors or lieutenant governors are analysed. The provincial constitutions are taken to determine the electoral regime, the political and constitutional reforms, and the laws that specifically have to do with the electoral participation of women, seeking to find out if these laws refer to executive candidacies. The main findings show that there was no spillover effect that incorporated women as executive candidates from the legislative affirmative measures, given that the percentage of participation was low throughout the period, in all provinces and for both competing positions, above all for the government.

Mujeres en el encuadre: la construcción de fetiches profanos y la atracción de los públicos; Women in the Frame: the Construction of Profane Fetishes and the Attraction of Publics Flores, Silvana Noelia El objetivo de este artículo es estudiar un ciclo de films mexicanos que acusan una fórmula narrativa basada en la confección de cuadros de desnudos femeninos: La fuerza del deseo (Miguel M. Delgado, 1955), El seductor (Chano Urueta, 1955), La ilegítima (Chano Urueta, 1956) y La Diana cazadora (Tito Davison, 1957). Estos aprovecharon el aligeramiento de los códigos de la censura, y representaron al cuerpo femenino como fetiche profano e instrumento de atracción del público. Realizaremos un análisis narrativo y de la puesta en escena de dichos films, focalizando en las secuencias específicas en las que sus personajes participan de la confección de los cuadros. Los pondremos en confrontación con sus referencias en otras cinematografías y con sus implicancias estético-narrativas en el enfoque industrialista, destacando las propuestas publicitarias que emplearon para su instalación en el mercado nacional e internacional.; The objective of this article is to study a group of Mexican films that accuse a narrative formula based in artistic works of female nudes: La fuerza del deseo (Miguel M. Delgado, 1955), El seductor (Chano Urueta, 1955), La ilegítima (Chano Urueta, 1956) and La Diana cazadora (Tito Davison, 1957). They took advantage of the lightening of the censorship codes and represented the female body as profane fetish and as an instrument of attraction of the public. We will make a narrative and staging analysis of those films, focusing in the specific sequences where their characters participate in the making of paintings or sculptures. We will put them in confront with their references in other cinematographies and with their aesthetic-narrative implications in the industrialist focus, highlighting the publicity proposals used for their installation in the national and international market.

Ideas e ideologías en la Argentina de los años 20: el antifascismo antes del antifascismo; Идеи и идеологии в Аргентине в 1920-е гг.: антифашизм до антифашизма; Ideas and ideologies in Argentina in the 1920s: anti-fascism before anti-fascism Pasolini, Ricardo Oscar El artículo intenta desarrollar un análisis de las ideas que se elaboraron acerca del antifascismo en la Argentina de los años 20. Para ello, estudia una serie de revistas culturales de orientación ideológica cosmopolita y/o de izquierda (Nosotros, Los pensadores, Claridad, Valoraciones, Izquierda, Sagitario). Se propone la hipótesis de que en un contexto global de circulación de ideas, el modelo político fascista se analiza con curiosidad, se impugna su componente antiobrero y autoritario, pero es reconocido como una expresión específica de la vida política italiana, de imposible desarrollo en Argentina. A diferencia de lo que sucederá en la década de 1930, el antifascismo fue un componente no central del debate político nacional durante esos años.; В статье предпринята попытка анализа представлений об антифашизме, сложившихся в Аргентине в 1920-е годы. Для этого автор обратился к исследованию серии культурных журналов космополитической и/или левой идеологической ориентации (Nosotros, Los pensadores, Claridad, Valoraciones, Izquierda, Sagitario). Выдвигается гипотеза о том, что в глобальном контексте распространения идей фа шистская политическая модель привлекала всеобщее внимание, при этом оспаривается ее антирабочая и авторитарная составляющая, и фашизм признается специфическим выражением итальянской политической жизни, неприемлемым как вариант возможного развития Аргентины. В отличие от того, что произошло в 1930-е годы, в предыдущее десятилетие антифашизм не был центральным компонентом национальных политических дебатов.; The article attempts to develop an analysis of the ideas that were developed about anti-fascism in Argentina in the 1920s. To do so, it studies a series of cultural magazines with a cosmopolitan and/or left-wing ideological orientation (Nosotros, Los pensadores, Claridad, Valoraciones, Izquierda, Sagitario). The hypothesis is proposed that in a global context of circulation of ideas, the fascist political model is analyzed with curiosity, its anti-worker and authoritarian component is challenged, but it is recognized as a specific expression of Italian political life, of impossible development in Argentina. Unlike what would happen in the 1930s, anti-fascism was a non-central component of the national political debate during those years.

Extractivismo, narrativas del desarrollo y el mito del «efecto derrame»: el caso de la minería del litio en Argentina; Extractivisme, récits de développement et mythe de «l’effet de retombée»: le cas de l’exploitation minière du lithium en Argentine; Extractivism, development narratives and the myth of the «trickle-down efect»: the case of lithium mining in Argentina Gómez Lende, Sebastián El litio es un metal clave actualmente para la transición energética posfósil, la electromovilidad y la economía verde. En ese contexto, su explotación aparece en la narrativa del capital y el Estado como un nuevo El Dorado capaz de promover el enriquecimiento del erario público y lograr el desarrollo nacional, regional y local. Valiéndose de estadísticas e informes oficiales, bibliografía académica, reportes corporativos e información periodística, este artículo contrasta el discurso hegemónico (el mito) con las condiciones materiales objetivas (la realidad) de la minería del litio en Argentina, cuarto productor y exportador mundial de este mineral. Para ello, utiliza cinco categorías de análisis: los discursos de las élites políticas domésticas; la dinámica exportadora del sector; la política tributaria y la recaudación impositiva; las políticas de «responsabilidad social empresarial»; y el acceso a servicios básicos de la población local implicada. Los hallazgos refutan el imaginario «efecto derrame» propalado por el discurso hegemónico, demostrando que el boom exportador de la actividad implica magros aportes al fisco, evasión impositiva y persistentes déficits infraestructurales.; Le lithium est actuellement un métal clé pour la transition énergétique post-fossile, l’électromobilité et l’économie verte. Dans ce contexte, son exploitation apparaît dans le récit du capital et de l’État comme un nouvel Eldorado capable de favoriser l’enrichissement du trésor public et de réaliser le développement national, régional et local. À l’aide de statistiques et de rapports officiels, de bibliographies universitaires, de rapports d’entreprises et d’informations journalistiques, cet article oppose le discours hégémonique (le mythe) aux conditions matérielles objectives (la réalité) de l’exploitation minière du lithium en Argentine, quatrième producteur et exportateur mondial de ce minéral. Pour ce faire, cinq catégories d’analyse sont utilisées: les discours des élites politiques nationales; la dynamique des exportations du secteur; la politique fiscale et la perception des impôts; les politiques de responsabilité sociale des entreprises; et l’accès aux services de base pour la population locale concernée. Les résultats réfutent l’imaginaire «effet de retombée» propagé par le discours hégémonique, prouvant que le boom des exportations de cette activité implique de maigres contributions au Trésor, l’évasion fiscale et des déficits infrastructurels persistants.; Lithium is currently considered as a key metal to ensure the post-fossil energetic transition, electromobility, and the «green» economy. In the state’s and capital’s narrative, its exploitation appears as a new Eldorado, capable of promoting the enrichment of the public treasury and conquering the national, regional and local development. On the basis of official statistics and reports, scholar bibliography, corporative reports and journalistic information, this paper contrast the hegemonic discourse (the myth) and the objective material conditions (the reality) of the lithium mining in Argentina (i.e. the fourth major producer and exporter of such mineral) by using five categories of analysis: the speeches of the domestic political elites; the exports dynamics of the sector; the tax policy and collection; the policies of Corporate Social Responsability; and the access of the local communities to the basic services. The findings refute the imaginary «trickle down-effect» spread by the hegemonic discourse, demonstrating that the export boom of such activity results in meager contributions to the treasury, tax evasion tactics, and persistent infrastructural deficits.

Environmentally friendly surface treatments used to avoid algal colonization on mortars Correa, María Verónica; Rastelli, Silvia Elena; Gómez de Saravia, Sandra Gabriela Biodeterioration is a major problem with construction materials. Presence of biofilm, biofouling, or biopatina, causes decomposition processes of the material both on its surface manifesting as undesirable aesthetic alterations as well as within the material. In this study, two environmentally friendly treatments were evaluated in an attempt to prevent the growth of phototrophic biofilms on mortar surfaces. Those surfaces were treated using a water-based solution with surfactants with and without thymol 1 %. The algaecide effect was evaluated, leaving a set of samples without treatment as a control of algae growth. The inoculum used in the tests was an algae community isolated from the mausoleum studied. Samples were inoculated with this community and they wereincubated under controlled photoperiod and temperature conditions for 30, 60 and 120 days. For surfaces treatments stability assay, other mortars samples were inoculated 30, 60 and 90 days after surface treatments were applied. For surfaces studies were used stereoscopic microscopy, Environmental Scanning Electron Microscopy and epifluorescence microscopy, also surface contact angle and colour and bright were measured. Both treatments inhibited algal growth in mortar surfaces. We propose that these surface treatments would be potentially useful for cleaning and preventing phototrophic formation of biofilms on historic buildings.

Fingerprinting of monovarietal olive oils from Argentina and Uruguay via stable isotope, fatty acid profile, and chemometric analyses Spangenberg, Jorge Enrique; Lantos, Irene Johanna Tracing methods of non-European EVOOs commercialized worldwide are becoming crucial for effective authenticity controls. Limited analytical studies of these oils are available on a global scale, similar to those of European EVOOs. We report for the first time the fatty acid concentrations, bulk-oil 2H/1H, 13C/12C, and 18O/16O ratios and fatty acid 13C/12C ratios of 43 authentic monovarietal EVOOs from different geographical regions in Argentina and Uruguay. The samples were obtained from a wide range of latitudes and altitudes along an E–W profile, from lowlands near the Atlantic Ocean to the pre-Andean highlands near the Pacific Ocean. Principal component scores were used to cluster EVOOs into three groups— central-western Argentina, central Argentina, and Uruguay—based on nine stable isotope ratios and the oleic-linoleic acid concentration ratio. The bulk 2H/1H and 18O/16O values and 13C/12C of palmitoleic and linoleic acids provide good tools for differentiating these oils via linear discriminant analysis.

Emergencia en la emergencia: La protección social en tiempos del Covid-19 en la Argentina; Emergency in the emergency: Social Protection in the time of Covid-19 in Argentina Krmpotic, Claudia Sandra; Lucuix, Maria Beatriz En este artículo, se recupera una modalidad como es el estudio de coyuntura a partir de datos primarios y secundarios como vía de abordaje descriptivo de experiencias recientes. Se exponen rasgos distintivos de las políticas sociales de alcance nacional como resultado de una revisión de contenidos en la información pública, y de un estudio de caso a partir del procesamiento de datos sobre dos barrios periurbanos de ciudades intermedias de la Provincia de Misiones. A modo de hipótesis de trabajo, nos preguntamos si la pandemia ha promovido un fortalecimiento del papel estatal con algún tipo de innovación frente al nuevo fenómeno epidemiológico, o si, en todo caso, las acciones respondieron a la acumulación de bienestar del que ya se disponía con una sostenida tendencia asistencial, mientras se fortalecieron las redes de cuidado intrahogar y los soportes comunitarios.; In this article, we use primary and secondary data as a descriptive approach to recent experiences in the form of a situational study. The article highlights distinctive features of national social policies by reviewing public information contents, including a case study based on data processing from two peri-urban neighbourhoods in intermediate cities in the province of Misiones. As a working hypothesis, we discuss whether the pandemic has strengthened the role of the goverment with some innovation in the face of the new epidemiological phenomenon, or whether the policies responded to the accumulation of the already available welfare with a sustained assistential tendency while, at the same time, intra-household care networks and community support were strenghtened.
